In the automobile production and manufacturing process, a large number of welding processes are involved, and laser brazing is a brazing process which is completed by utilizing high energy density of laser to realize rapid heating of local or micro areas. In the automobile industry, laser brazing equipment in a welding workshop has high quality and strength, and a welding bead is attractive and has strong corrosion resistance, so that the method is a good choice for various automobile manufacturers. Because the automation rate of modern factories is high, the production beat is fast, if the laser brazing is accidentally broken in the welding process, after the welding wire is adhered to the automobile body, the robot continues to move, the wire guide module of the laser lens is pulled and deformed to cause the TCP (tool center point) of the lens to shift, and the wire guide module needs to be artificially corrected to restore the initial TCP position. At present, when a guide wire module is restored, restoration is completely carried out by a manual method, and TCP is verified by using a welding wire head to check TCP corresponding to a sharp object or by using a laser spot and the welding wire head to be matched. However, the wire guide module cannot be controlled to deviate in the rotating direction by using the welding wire head to check the TCP corresponding to the sharp object, TCP verification is carried out by using the laser spot and the welding wire head in a matching manner, the recovery needs to be carried out by experience and naked eye observation, and the effect is not obvious. The conventional method for correcting the guide wire module is labor-consuming and needs to be verified respectively for different vehicle types, so that the production time is seriously influenced. And the wire guiding module is fixed by the bolt, and because the external force can still be dragged and deviated, the TCP still has deviation after the wire guiding module is recovered artificially, and cannot be reset accurately.
