It can be in judging whether upper lower girder welds completion, if integral solder is complete by increasing a detection judgment step S700 At then latch assembly leaves location hole, and upper lower girder is released blanking by pusher motor, if integral solder does not complete, carries out down The welding of one pad.

Further, the girder method for laser welding, wherein further include step before the step S200:

The height of side welding plate has been adapted to by the distance that upper and lower adjustment mechanism adjusts upper lower girder.

The height of upper support frame is adjusted by about the first adjustment mechanism, about the second adjustment mechanism adjusts lower bracing frame Highly, the distance between the upper lower girder for being individually positioned in upper support frame and lower bracing frame can be adjusted, to be suitable for side welding plate Height.

The girder method for laser welding that the present invention uses, compared with existing technique, the method for the present invention is set by automation Standby a series of actions, the feeding and welding of lower girder and side welding plate in completion, compared to traditional girder Joining Technology, production High-efficient, the quality of production is high, and cost of labor is low.

It should be understood that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations, to ability It for field technique personnel, can modify to technical solution illustrated in the above embodiments, or special to part of technology Sign is equivalently replaced;And all such modifications and replacement, it should all belong to the protection domain of appended claims of the present invention.
