1.Application of laser welding machine in automobile seat screw rod
The automobile seat screw rod is equipped with 2kW fiber laser, two stations and a production capacity of 500pcs / h, which is specially used for the welding of automobile electric seat adjustment screw rod. The safety and reliability of car seats is very important, which requires that the laser welding machine must be stable and reliable. Therefore, the welding quality real-time monitoring system is adopted in the system configuration to monitor the welding quality in real time. If there is any abnormality, it will be automatically identified to ensure that the defective products flow into the next process.
2.Application of laser welding machine in high pressure fuel rail of engine
The welding of the high-pressure fuel rail of the engine is mainly to manually put the oil pipe and fuel injection nozzle into the fixture, press the start button, and the automatic detection system will automatically identify whether the placement position and type of fuel injection nozzle are correct, and then enter the next procedure for welding. If it is incorrect, an alarm will be sent out. After welding, judge whether the welding is normal according to the system information during welding, the good products enter the next processing link, and the bad products are put into the bad product box. This is mainly to use the laser welding machine for precise positioning before brazing, so as to ensure that there will be no offset in the brazing process, so that the design accuracy can be accurately achieved after welding.
The development of automobile industry puts forward higher requirements for welding quality. Laser welding machine is more and more widely used in automobile production. It gives full play to its advanced, fast and flexible processing characteristics in automobile industry. It is not only higher than traditional welding methods in productivity, but also significantly improved in welding quality.
3.Application of laser welding machine in automobile sensor
With the intelligence of the automobile, there are more and more sensors on the automobile. A large part 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. In this system, CCD visual positioning module is used to determine the welding position through CCD. At the same time, because there are many kinds of sensors, different tooling fixtures are required. Therefore, the auto sensor welding system also adopts the tooling fixture automatic identification system, By identifying different fixtures, the control system automatically calls the corresponding programs and welding parameters.
4.Application of laser welding machine in relay sealing
The relay sealing laser welding machine is fully computer programmed, which can realize full-automatic butt welding and sealing welding. The relay sealing laser welding machine exclusively studies the laser welding of complex plane, straight line and circular arc. First, it has been invested in the welding of various elbow pipes, kettle, bathroom hardware, tee pipe, faucet and shower equipment. It implements long-distance flexible non-contact welding where it is difficult to weld. It also has strong flexible control ability, and multi beam simultaneous welding provides more precise welding technology.
Advantages of relay sealing laser welding machine
1.Automatic fixture customization to realize mass production.
2.Corrosion resistance, high temperature resistance, cavity life extension, laser xenon lamp life increase.
3.The welding quality is more stable, with all appropriate spots required for welding.
4.It is suitable for various complex welds, spot welding of various devices, and seam welding of thin plates within 1mm.
5.CCD camera monitoring system is selected to facilitate observation and accurate positioning, and the energy distribution of welding spot is uniform.
