Flying laser welding technology is appeared on the market at home and abroad in recent years a new type of high efficient welding technology, compared with traditional laser welding technology, laser welding is flying through the use of the robot control of laser welding is a new type of scanning process, for more welding can greatly improve production efficiency.
Laser welding flight scanning head can be laser welding from the location of the 500 mm outside, in the case of not mobile scanning head, through the movement of the scanning mirror, welding can be scanned for similar light.
Such a high speed, mobile location precision welding way, high-speed welding due to the scan head itself and external volley feeling of the space, so called 'flying welding'.
Zhongtai flying car welding production line laser welding has been successfully used on the door, the formation of a number of technical precipitation, which lay a foundation for subsequent large-scale application of the advanced technology.
Flying laser welding system, real time trigger, robot, scanning by laser head (
, optical components, such as through the optical fiber transmission of solid-state laser laser room located at a distance, it is to provide the driving force of welding energy.
Scan head is located in the laser optical fiber cable ends, laser focus precise positioning to will be in the middle of the welding.
Scanning head inside the two guide beam scanning mirror with normal lens focus on common focus plane of the beams, the welding range ellipse in general to a certain size.
In addition, the scan head also is equipped with an electric lens, you can move up and down along the Z axis direction focus plane.
Laser welding and traditional laser welding is not the same as the main difference is that the laser beam positioning method, laser welding technology by the incident laser beam to scan mirror flight of X, Y axis on the two mirrors, computer control the Angle of the mirror, achieve any deflection of the laser beam.
Through the lens of negative linear movement, the focus position in Z direction produce certain adjustment range, through a certain power density of laser focus in processing different locations on the surface of the workpiece to realize welding connection.
Compared with the resistance spot welding, the use of laser welding, continuous mobile scanning head and scanning mirror rapid positioning of the laser focus, to avoid the torch from a welding position to another position, shorten the reset time.
In laser welding work within the scope of flight, from starting point focused laser beam repositioned to the other side only need 30 ms.
For example, for the thickness of the sheet metal pieces of 0.
8 mm body, usually each welding point about 3 s using resistance spot welding is complete, but using laser welding flight time is less than 0.
4 s and welding effect is better than that of resistance spot welding, the welding efficiency increased 7 times.
Therefore, the application of laser welding flight greatly improved the production tempo.
Compared with the traditional resistance spot welding process, laser welding flight with weld characteristics of non-contact, flexible, welding lap surface may be smaller.
Traditional spot welding in order to ensure the quality of solder joint and avoid spot welding, welding defects such as the door window frame welding edge of 12 mm at least.
The zhongtai automobile research and development of a new application of laser welding technology flight car door window frame, its minimum window frame welding position of weld edge is 5 mm.
Application of laser welding flight can to A certain extent, reduce weight, also can reduce the window frame in black edge width, enlarges the a-pillar vision, raise the safety of the vehicle.
Compared with spot welding, arc welding, laser welding in the doors can be much reduced when welding the welding deformation, is conducive to the late assembly accuracy of debugging, especially steel cover class parts accuracy requirement, and matching function requirements are higher, make the assembly accuracy is guaranteed.
