The sensor is a detecting device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information transmission, processing, storage and display. Requirements for records, records, and controls. Sensors have long penetrated into areas such as industrial production, space development, ocean exploration, environmental protection, resource surveys, medical diagnostics, bioengineering, and even cultural relics protection.
Whether the sensor green laser pointer has a high technical added value is reflected in whether the technology content and processing technology involved are high. Some sensors require metal packaging due to the condition of their application environment. Generally, laser welding machines are used for welding and sealing. The welding quality is high, and the welding process requires small deformation and cannot damage internal components and microcircuits.
Sensor laser welding machines can be used for almost all metal welding. Compared with the traditional welding technology, the sensor laser welding machine has high efficiency, deep width ratio, no need for subsequent processing, and small heat-affected zone.
The main parameters affecting the welding of green laser pointer are welding current, pulse width, pulse frequency, etc. The main effects are as follows:
1. As the current increases, the width of the weld increases, the welding process gradually splashes, the surface of the weld appears to be oxidized, and there is a rough feeling.
2. As the pulse width increases, the width of the weld increases. The effect of pulse width variation on the effect of laser welding of stainless steel ultra-thin plates is very significant. A small increase in pulse width may cause the sample to be oxidized and burned through.
3. As the pulse frequency increases, the solder joint overlap rate increases and the weld width increases first. After that, it remains basically unchanged. Observed under the microscope, the weld seam is getting smoother and more beautiful. However, when the pulse frequency is increased to a certain value, the welding process is severely splashed, the weld seam becomes rough, and oxidation occurs on the upper and lower surfaces of the welded part.
4. Laser welding of ultra-thin plate material is suitable for positive defocusing. In the case of the same amount of defocusing, the surface of the weld obtained by defocusing laser welding is smoother and more beautiful than that of negative defocusing.
Sensor green laser pointer welding machine advantage: the sensor is very sensitive to the sensitivity, for its welding process we can only choose the welding machine with the same precision as it is to achieve the maximum effect, to avoid errors. Laser welding machines are gradually replacing the status of traditional welding machines and are accepted by the majority of sensor manufacturers.
1, can be processed at the welding point, especially suitable for mold polishing that needs to be repaired;
2. It can make long distances, high temperatures, dust, vibration, etc. in harsh environments such as welding;
3. It does not affect the welding after etching, the oxidation rate is low, and the color of the processed parts is complete;
4, the laser can be divided into time interval and power, suitable for a variety of applications, multiple worktables can be welded at the same time;
5. It uses an advanced laser power real-time feedback control system. Therefore, it can avoid the impact on the power fluctuation of the laser power, the temperature of the water and the aging of the xenon lamp. It can make solder joints of the same size and depth.
