[0034] When the second servo motor 5 drives the first slider 7 and the laser welding structure to slide left and right, the auxiliary slider 16 also slides left and right on the auxiliary guide rail 15, thereby providing assistance for the laser welding module to move left and right.

[0035] When the third servo motor 8 drives the first rotating structure and the laser welding module to move up and down, the vertical guide rail 19 moves up and down in the fixed slider 18, thereby providing assistance for the laser welding module to move up and down.

At the same time, the first servo motor and the fifth servo motor also continuously adjust the position of the assembly (including front and back movement and rotation), so that the laser welding module and the assembly cooperate closely to complete the multi-point laser welding of the diagonal iron and the side plate.
