The second level of the 1uf capacitor C2 for the coupling of the two-stage amplifier. The first stage of the amplifier input and ground to R3; the second stage amplifier input and ground indirect R7. The op amp is the equivalent resistance of the negative input terminals are equal, thus reducing the operational amplifier offset voltage. Rectangular pulse signal of the photocell output pulse is not a rule, but similar to the raised cosine signal. Will produce distortion, then the amplified signal shaping. The material of Laser Pointers is being purchased.
CD4093 Schmitt trigger can be used for shaping function to improve the pulse waveform, and to ensure follow-up encoder coding. Schmitt trigger not only the waveform shaping, hysteresis characteristics can also be effective to overcome the noise 8 Hangzhou University of Electronic Science and Technology graduate and interference, as long as the size of the noise and interference in the hysteresis, there would be the wrong output. Schmitt Trigger is the trigger level slowly varying signal is still applicable when the input signal reaches the threshold voltage, the circuit state conversion by the positive feedback process of the circuit inside the edge of the output voltage waveform becomes very steep. star laser pointer can be standardized if necessary.
Schmitt trigger the identification of effective pulse as shown in Figure 4-5. Inverted output Figure 4-5 Figure 4-4 Schmitt trigger voltage transfer characteristics (a) phase output; (b) signal of the Schmitt trigger the identification of effective pulse 4.3 coding circuit [11] 38 Road channel, it must be encoded in order to signal recognition and transmission. 38 signals in accordance with the design code for the 1-38, off target signal is recorded as the number of 0. Multiple detector receives the signal, corresponding to the detector code is to take a large detector for effective priority encoder can be encoded preference. The reasonable purchase of star laser pointer should be planned.
Commercial single priority encoder encoding input is at most 8-way, to constitute a more road priority encoder 6 8-3 priority encoder can be used to expand 40-6 priority encoder device. 4.3.1 The encoding circuit shown in Figure 9, Hangzhou University of Electronic Science and Technology graduate design the 4-640-6 priority encoder circuit diagram 4.3.2 Circuit Theory (1) the priority encoder (74HC148) 8-3 Line Priority Encoder menu 3-7. Eight input lines to be encoded I 7 ~ I 0 8 take one yards, logic 0 is valid, the encoded output A2 A1 A0 with the anti-code. It can be seen that the encoder input is 0 the highest priority encoder, and low if the input is meaningless. The supply management of star laser pointer is included in the procedure.

The detector will be a small number of lead and design accuracy is not high; detector quantity expensive, can not promote; only a rough indication hit or not, can not hit the target accurately show the ring number and orientation. Therefore, we intend these directions for further research and exploration. This design uses a semiconductor laser and semiconductor surface array of detectors to simulate bullets, and shooting targets, with a realistic simulation, and high accuracy. From the signal processing section laser targeting system, each shot accurately display the results of 5-10 ring and off target, each ring number can be divided into eight offset direction.

Current lasers are generally used in semiconductor laser output power of this laser does not damage the eyes, and high efficiency, low power consumption, can not only get rid of the large and heavy power equipment, laser itself can also be made small very light. Photodetector [6] the shape of a shooting target, point detectors and the detectors, usually in larger quantities to constitute a multiple signal detection pathway. The design of waterproof laser pointer should be updated.
According to the response of the photodetector position to determine the laser shot hit the target. Laser target practice with the to Mitsuyo bombs in the form of shooting training is the most common type of laser weapon simulator. The initial laser targeting system can only aim and shoot training with the development of computer and microprocessor technology, its use expanded to a variety of weapons simulation training. With the deepening of research and exploration, the function of the laser targeting system will further improve and be even closer to the performance of weapons and equipment in actual use, enhanced realism. At the same time, by combining with electronic technology, to further improve the automation of laser simulation, intelligent level. The manufacture system of waterproof laser pointer should be upgraded.
Laser weapon simulators are the development trends of the following aspects: can simulate more and more weapons, laser weapons simulator is moving the series, the direction of development of the components of a laser shooting simulator is modified can be applied to other weapons systems. Series, a component of the benefit is ease of use, replacement and maintenance, while prices are cheap. Shooting Simulator from the laser to laser engagement simulator, the organic combination of advanced laser engagement simulator can make tanks, fighting vehicles, anti-tank weapons training, each weapon is both attacker is an attacker, fully mimic the actual operational environment. This is another goal of the good purchase of waterproof laser pointer.

Not only improve the skills of the soldiers to use weapons, you can also teach them how to protect themselves in the war. Hangzhou University of Electronic Science and Technology graduate design using a variety of new technologies to increase simulation realism, such as a computer to record and control the process of training exercises, to assess the performance of soldiers in the exercises. The design idea of this design in order to achieve a good signal detection and data conversion, transmission as the main purpose; signal detection, signal encoding and data transmission as the main design. The design of a single pulse signal amplifier circuit in the signal detection and signal shaping circuit; in terms of signal coding, to solve the multi-channel signal encoding, but also consider the preference to coding. The core goal of Laser Pointers will be introduced.
Synchronization (see Chapter II hardware design part) off target approach, targeting and signal acquisition, transmission, off target and the target is classified as a class processing; data transmission using a UART serial communication. R & D direction and key technologies. Rational division of the photodetector of the laser target, to improve the accuracy of the system; single-pulse amplification and shaping of small-signal; the expansion of multi-channel priority encoder; and PCs for data transfers, facilitate the statistics of the results, save, display and query. The main technical indicators of the laser pulse: shooting distance: serial output frame format: greater than 1ms 30 meters Shots + hit number of photoelectric detectors. Laser pulse response amplitude. The supply management of waterproof flashlights has been enhanced.
About 10 mv Hangzhou University of Electronic Science and Technology undergraduate graduation design of the overall design of the laser targeting system is a set of optical power in one system, and its working principle is a laser beam from the laser gun, hit a photoelectric sensor, photoelectric sensor convert optical signals into electrical signals, the signal after signal processing by the microcontroller to the computer's serial port, and then on the computer results show that query and save. The laser targeting system block diagram of the structure shown in Figure 3-1. The system includes a semiconductor laser guns, modular detectors, digital signal processing and transmission circuit, and computer data processing program of four parts. It is finding the better supplier of waterproof flashlights.
Each targeting laser gun emits a laser pulse. If the laser pulse hit the photoelectric target, the use of photovoltaic effect, photoelectric target detector to convert optical signals into electrical signals, so the detection of the laser detector response signal detection. The response of the photodetector is a single pulse signal, the entire testing process including: signal amplification, waveform shaping, the detection output is a standard pulse digital signal. The target for the division of a laser target is divided into 38 detector, center ring 10 to a detector; 9.8.7.6 ring of eight detectors; ring with five detectors. According to different targets on the detector to determine the location of the hit, including the number of rings: 10.9.8.7.6.5. It is developing the competitive supplier of waterproof flashlights for the enterprise.
Deviation from the direction: left. Right. Upper left. Lower left upper right. Bottom right. If the signal hit the junction of two or four detectors, only take one piece, note the following conditions are met: high number of rings for the effective detector; deviation from the direction of the diagonal (for example: on the upper right in two directions, select upper right). Different detectors according to the above requirements, as well as the needs of the hardware circuit design, coding, as shown in Figure 3-2 (right). Figure 3-2 target classification and numbering 3.3 coding standard 38 signals according to the above principle of coding, coding results are shown in Table 3-1. Off target and no signal is recorded as the number of 0. Encoded, each number corresponds to the location information of each detector, including the ring number and the offset direction. The product of waterproof flashlights is in the better quality.

The ultrasonic welding used in the manufacture of copper or aluminum to the electrical interface is also more common in the welding of composite materials. Another common solid-state welding process is explosion welding (Explosion welding), and its principle is to form a connection under high temperature and high pressure material produced in the explosion. The impact of the explosion makes the material a short period of time to show plasticity to form the solder joint, this process produces only a small amount of heat. This process is usually used to connect the welding of different materials, such as aluminum components connected to the hull or composite board. The advice and suggestion of cheap Laser Pointer is from the technical personnel.
Narrow weld: the smallest angle deformation and lateral contraction to save the cost of technology: the welding speed, high production efficiency; optimize the design of more traditional means, can reduce the cost; no need accessories; prior to welding only need very simple standard working material optimization : Social and welding materials, varieties, a wide range of acceptable materials of different types of welding automation of the production process: electrical parameters of all the process parameters, so you can easily carry out the measurement control and testing in other words, electron beam welding its depth is relatively deep, laser welding 15mm maximum depth of electron beam welding can reach 95mm or larger, as the case may be. led disco lights can have the new performance and function the customer needs.
They have co-operation with companies such as Rofin Sinar. Using a CO2 laser-based remote welding equipment, the use of the scanning lens to the reflected beam high-speed welding body parts more than one welding position. In a typical part of the Fiat Marea models, remote CO2 laser welding has also been used to replace resistance spot welding, in order to eliminate the cost by the adhesive on the rear tailgate. In this application, the total laser seam welding time is 5s. 43 laser weld in the welding of the door frame of the model, only 30s can be done to replace the traditional resistance spot welding. In this application, the repeatability of positioning time fell as much as 94%. The drawing of led disco lights should be prepared at the same time.
The operator simply accept a small amount of training can be mastered. The welding time is slower, because of the consumable electrode electrode must be changed frequently. Also need to clear the welding flux welding slag. In addition, this technology is often used for welding ferrous metals, welding cast iron, nickel, aluminum, copper and other metals need to use a special electrode. Lack of experience of the operator is often difficult to grasp the special position of the welding. MIG arc welding (Gas metal arc welding, GMAW), also known as metal - inert gas welding or MIG welding is a semi-automatic or automatic welding process. It uses electrodes of continuous wire feed as an electrode and inert or semi-inert gas mixture to protect the solder joints. Especially the commission of led disco lights should be carefully and exactly carried out.
Other solid-state welding processes, including extrusion welding (Co-extrusion welding), cold welding (Cold welding), diffusion welding (the Diffusion welding), Friction Welding (Friction welding) (Friction Stir Welding (Friction stir welding), high frequency welding ( High) frequency welding), hot pressing, welding (Hot pressure welding), induction welding (Induction is welding), hot rolled welded (Roll welding) [25]. The connector type common type of welded joints: (1) butt joints; V-shaped butt joint; lap joint; T-shaped connector. The welded connection between the workpiece can be a variety of joint form. The production task of the green led disco lights is very tense.

At present, Germany's Volkswagen in the Audi A6, Audi A4, Golf and Passat and other roof using this technology, the BMW 5 Series, Opel Vectra models, and the Swedish Volvo models production of laser welding is a rush . In China, Shanghai Volkswagen has been used in many models of laser technology to weld the roof and side wall outer plate, such as the Passat, Touran, etc.; Shanghai GM new Regal, LaCrosse platform application of laser welding technology. Figure 1 is the new Regal Shanghai GM's roof and side wall of the welding device used in the of 4kW pump laser, weld identification, tracking systems and real-time monitoring of weld quality systems are all integrated in the laser welding head. The lead time of disco laser would be no less than one or two days.
It uses a tungsten electrode and the plasma gas to generate the arc. Plasma arc welding arc more concentrated relative to the protection of the gas tungsten arc welding, plasma arc welding of horizontal control is particularly important, this technology require a higher mechanical systems. More stable because of its current, tungsten inert gas shielded arc welding, deep welding, welding speed faster. It can welding the tungsten inert gas shielded arc welding of almost all metals, the only welding magnesium. Automatic welding of stainless steel is an important application of plasma arc welding. A variant of the process is plasma cutting for steel cutting. Submerged Arc Welding (Submerged Arc welding, SAW), is a high efficiency of the welding process. The meeting is to discuss the quality problem of cheap Laser Pointer.
With the birth of a new generation of lasers, the laser's life span can reach 50000h, which greatly reduces the cost of the use of laser welding equipment. However, in order to obtain the desired quality of welding, gas protection is essential, which also caused the increase in processing costs; laser welding depth to width ratio is less than the electron beam welding, is generally less than 10:1 (in the gear laser welding the weld depth of 4 to 6 mm, and therefore this aspect is still relatively applicable), not suitable for the welding of large thickness of the workpiece; laser welding of aluminum alloy and other high-reflectivity materials welding there are still some technical difficulties, we must filler wire and other auxiliary means, in order to achieve better welding effect. disco laser can be used by the customer to point to the star.
Warm-up can reduce the temperature gradient of the welding region, thereby reducing the thermal fracture. But the warm-up will also reduce the mechanical properties of the parent material, and can not be applied in the parent material is fixed. Using the appropriate form of joint compatibility better fill the alloy can reduce the thermal fracture appears. Aluminum alloy surface should be cleaned before welding, to remove oxides, grease and loose impurities. The surface cleaning is very important, because the welding of the aluminum alloy, the excess hydrogen will cause a bubble, too much oxygen in the formation of scum. Welding underwater welding under extreme environment to work in factories and repair shops can control the environment, some of the welding process can be carried out in a variety of environments such as outdoors, underwater, (such as space) vacuum. The technical personnel shall provide more advices of disco laser.
Dedicated lathe the processability ф1000m length 14m less than the parts. All structural parts using CNC cutting cutting edge milling machine to be assembled structures reinforcement to the underside of the knife check to increase the contact surface of the assembled parts to ensure a degree of parallelism, an increase of the rigidity and strength of the overall structure. Hydraulic support structure used in all our company developed a special six-axis boring machine and four-axis gantry boring machine for the overall processing and reliable way to ensure the structural hole between the position requirements and consistency of the structure size to solve the hole axial and position tolerance requirements of the problem, ensure R0.5 and R1mm, concentricity requirements, completely solved the structure of the assembly quality and interchangeability requirements. It is to guide the production of the new type of disco laser.

With the rapid development of technology, laser welding is gradually replaced by the electron beam welding, as the preferred technical solutions. The scope of application of laser welding, and welding, from the gear drive system parts welding, body welding, the backplane ranging from thick steel plate welded door welding and other fields. Therefore, the field of automobile manufacturing is the largest in the current industrial production of laser welding technology industries from auto parts to body manufacturing, laser welding has become one of the most important in the automobile manufacturing welding method. Generally speaking, laser welding in the automotive applications include welding of three areas: auto parts, laser welding laser welding in the automobile manufacturing began in the gears of the gearbox. More and more customers are getting interested in the cheap Laser Pointer.

Laser welding and laser brazing continuous, remote laser welding is growing rapidly, its advantages have been highlighted. The workshop should manage the production plan of stage lighting effects.
Inversely proportional to the weldability of steel of different steel materials with its own hardening characteristics, hardening characteristics is generated during the martensitic steel welding cooling capacity. Depends on its chemical composition the hardening characteristics of steel, a steel material containing a higher proportion of carbon and other alloying elements, and its hardening characteristics of indicators of higher weldability is relatively low. To compare different alloy steel weldability, can be used in a method called the equivalent carbon content, it can reflect the different alloy steel weldability of plain carbon steel. For example, chromium and vanadium on the the weldability impact than copper and nickel, the impact factor of alloying elements than carbon should be small. The higher the equivalent carbon content of alloy steel, the weldability lower. The provider should deliver stage lighting effects in the good quality and high performance.
Such as controlling the content of oxygen in the air, the inflammable and explosive materials to separate stacked. Welding smoke extraction equipment commonly used to pumping the bulk of harmful gases, and high efficiency baffle air filter to filter. Economic and development trends of the economic costs of welding is an important factor of industrial applications. Welding the cost of many factors, such as equipment, manpower, raw materials and energy costs. Welding equipment costs vary widely for different processes, manual metal arc welding and gas welding relatively low-cost, laser welding and electron beam welding the higher cost. Due to the high cost of some of the welding process, it is generally used in the manufacture of important components. The automatic welding equipment and welding robot equipment costs are also high. The workshop will definitely manage the lean production of stage lighting effects well.
In recent years, the company has developed Datong, Yangquan, Long coal, Shenyang and Fuxin, Liaoyuan, Xingtai more than 20 domestic and foreign group companies (Bureau) of the complete set of support equipment. Galvanizing process. Introduction to plating process. Electroplating concept: electroplating is the use of the electrolytic process for processing the part surface. Plating parts is the cathode, the metal ions in the bath in the role of the DC current in the metal deposited on the surface to form a uniform, dense metal coating. Plating conditions: the essential conditions of the plating is the external dc power supply, bath and plated pieces and anode composition of the electrolytic device. Exclude the interference of other cations, and uniform coating, solid solution required to contain the plating metal cations do the plating solution in order to keep the coating metal cation concentration constant. stage lighting effects can be submitted and accomplished timely.

Laser and metal interaction process, the metal melt is only one of the physical phenomena. Sometimes the light is not mainly converted into metal melting, and other forms of performance, such as vaporization, plasma formation. However, to achieve a good molten weld metal melt to become the main form of energy conversion. Therefore, we must understand the various physical phenomena arising from the interaction between laser and metal as well as the relationship of these physical phenomena and laser parameters, and thus by controlling the laser parameters, the laser energy is mostly converted into the energy of the molten metal to reach welding purpose. Therefore, the good effect of green laser pointer 5mw for the star gazing can be realized.
Laser welding the welding process several effects. Laser welding plasma welding process. Plasma formation in conditions of high power density laser processing and will appear in the plasma. Plasma generation material atoms or the division of energy excitation ionization, any substance in the receiving outside energy and temperature, the atoms or molecules by the energy (light, heat, electric field, etc.) excitation will produce ionization, which formed by the free movement of electrons with positively charged ions and neutral atoms in plasma. Plasma is often referred to as the fourth state of matter at the macro level to maintain a neutral state. Laser welding, the premise of the formation of plasma is heated to a temperature gasification. cheap Laser Pointers can be used for the city environment.
Metal by the laser heating gasification in the bath above the formation of high temperature metal vapor. The free electrons in the metal vapor. Free electrons in the laser irradiation area by the inverse bremsstrahlung radiation absorbed energy is accelerated until it has enough energy to collisions, ionization of metal vapor and surrounding gas, the electron density and thus increase the avalanche. This process can be approximated by the classic model of microwave heating and plasma is produced to describe. . Power of 10 W / cm, the average electron energy is dramatically increased with irradiation time longer a constant value (about 1cV) 7 2 10 Harbin Institute of Technology in the electron energy, the ionization rate advantage, the avalanche ionization The electron density is rising sharply. Because they might like the green laser beam light emitted by green laser pointer 5mw.
Finally reach the value of the electron density and recombination rate, but also with the protection of gas. Laser plasma processing of metal vapor plasma, This is because the ionization energy of the ionization energy of the metal material below the protective gas, metal vapor ionization than the surrounding gas is easy. If the laser power density is high, while the surrounding gas flow is not sufficient, may also make the surrounding gas dissociation and formation of plasma. The plasma behavior of high power laser deep penetration, the plasma in the top of the bath will cause the absorption and scattering of light, changing the focus position, reduce the concentration of the laser power and heat, can affect the welding process. green laser pointer 5mw is used to show others which stars they want to observe.
The plasma radiation absorbed laser energy by inverse bremsstrahlung, inverse bremsstrahlung is an important mechanism of the plasma absorption of laser energy is due to collisions between electrons and ions. Said simply: in the laser field, the high-frequency oscillation of the electronic collision and Guo will be a corresponding vibration can become irregular movement, the laser energy into plasma thermal energy of motion, the laser energy is plasma absorption. Plasma on the laser absorption rate and the electron density and is proportional to the vapor density, increase with the growth of the laser power density and time, and is proportional to the square of the wavelength. The same plasma. green laser pointer 5mw is for many different purposes.
