We all know that welding tips are widely used, especially in the automotive industry, because some countries have used laser welding tips in the automotive industry since 1969. In addition to being widely used in automotive body welding, laser welding heads are also widely used. In various automotive parts, such as automotive high voltage relays, filters, torque sensors, turbochargers, oil rails, cylinder gaskets, spark plugs, segmented motor stators, seat adjustment screws, airbags, etc. However, the requirements for different parts of the car are different. At present, many laser welding head manufacturers can no longer meet the requirements.
1. Application of laser welding head on car seat screws
Car seat screws are equipped with 2KW fiber laser, double station, capacity 500PCS/H, specially used for welding of car electric seat adjustment screws. The safety and reliability of car seats are very important, which requires the laser welding head to be stable and reliable. Therefore, the system configuration adopts the real-time welding quality monitoring system to monitor the welding quality in real time. Any anomalies are automatically identified to ensure that defective products flow into the next process.
2. Application of laser welding head in high pressure fuel rail of engine
The welding of the high-pressure fuel rail of the engine is mainly to manually put the fuel pipe and the fuel nozzle into the fixture, press the start button, the automatic detection system will automatically identify whether the position and type of the fuel nozzle are correct or not, and enter the next welding procedure after correct. If not, an alert message will be issued. After welding, judge whether the welding is normal or not according to the system information during welding. High-quality products go to the next processing step, while bad products go into boxes of inferior products. Its main purpose is to use the laser welding head for precise positioning before brazing to ensure that no deviation occurs during the brazing process, so that the design accuracy can be accurately achieved after the welding is completed.
The development of the automobile industry has put forward higher requirements for welding quality. Laser welding heads are more and more widely used in automobile production. They take full advantage of the advanced, fast and flexible machining characteristics of the automotive industry. Not only do they have higher productivity than traditional welding methods, but they also significantly improve welding quality.
3. Application of laser welding head in automotive sensor
With the intelligentization of cars, there are more and more sensors on the car. Most of these sensors are used such as torque sensor, ESP, oxygen sensor, engine position sensor and speed sensor. The size of the sensor is small and the welding position is also small. The system adopts CCD visual positioning module, and the welding position is determined by CCD. At the same time, due to the wide variety of sensors, different jigs and fixtures are required. The automotive sensor welding system also adopts the fixture and fixture automatic identification system. The corresponding programs and welding parameters automatically call up and identify the different fixtures and fixture control systems.
4, the application of laser welding head in relay sealing
The relay sealing laser welding machine is completely programmed by computer and can realize fully automatic butt welding and sealing welding. The relay sealing laser welding head specializes in laser welding of complex plane lines and arcs. Various elbow pipes, kettles, bathroom hardware, tees, faucets and shower fixtures have been welded, and long-distance flexible non-contact welding has been implemented for hard-to-weld places. In addition, it has powerful and flexible control capability, and multi-beam simultaneous welding provides more precise welding technology.
Advantages of relay sealing laser welding machine:
(1) Automated employee customization to achieve mass production;
(2) Corrosion resistance, high temperature resistance, prolong the service life of the cavity, and prolong the service life of the laser xenon lamp;
(3) The welding quality is more stable, and the light spots required for welding are suitable;
(4) Adapt to various complex welds, spot welding of various devices, and seam welding of 1mm thin plates;
(5) The CCD camera monitoring system is selected, which is convenient for observation and accurate positioning, and the energy distribution of the solder joints is uniform.
