9. A welding method for the automatic welding equipment for a cable tray chassis according to claim 8, characterized in that: The following steps are involved: Step 1: During operation, the required material plates are placed in the placement slots (18) respectively, and then the first and second electric push rods (50) drive the grabbing plate (15) to move, so that the first grabbing plate (15) is attached to the material plate in the first placement slot (18), and then the corresponding pneumatic suction cup (16) is started to adsorb the material plate, and the grabbing plate (15) is reset after adsorption. After the grabbing plate (15) is reset, the fourth servo motor (23) drives the motor gear to rotate intermittently, and the motor gear drives the third gear (25) to rotate. The rotation of the third gear (25) can drive the linkage shaft (46), and the rotation of the linkage shaft (46) can drive the first synchronous belt (22) and the first synchronous wheel (21) to operate, and the operation of the first synchronous belt (22) and the first synchronous wheel (21) can drive the second The gear (20) rotates, and the rotation of the second gear (20) can drive the first gear (19) to rotate. The rotation of the first gear (19) can drive the hollow shaft (27) to rotate 90 degrees each time. Each rotation of the hollow shaft (27) can realize the position switching of the grab plate (15) once. At the same time, each rotation of the linkage shaft (46) can drive the fourth gear (45) to rotate accordingly. The rotation of the fourth gear (45) can cooperate with the rack (47) to move the sliding platform (17). When the fourth gear (45) rotates each time, it can drive the placement slot (18) to move one station, so that when the grab plate (15) switches its position, the sliding platform (17) will move synchronously, so that the corresponding material plate will move to the bottom of the grab plate (15), thereby realizing the grabbing of the material plates one by one and splicing the material plates; Step 2: After the splicing is completed, the moving assembly drives the U-shaped frame (8) to move toward the rotating cylinder (3). After reaching the set position, the telescopic assembly drives the sliding arm (9) to synchronously retract into the hollow box (42), so that the right-angle positioning groove plate (29) positions the four corners of the spliced ​​material plate. After the positioning is completed, the fourth electric push rod (57) drives the locking pin to be pulled out to release the lock on the hollow tube (41); Step 3, then the first servo motor (30) drives the first threaded rod (13) to rotate and drive the lifting block (12) to move, so that the welding gun (11) moves to the welding position, and the second servo motor (34) drives the second threaded rod (33) to rotate, and the second threaded rod (33) rotates and drives the transverse slider (32) to move, and the transverse slider (32) moves to drive the welding gun (11) to move along the edge of the spliced ​​material plate in the avoidance groove (37) to complete the welding work of the current edge. After the welding of the current edge is completed, the fourth servo motor (23) intermittently reverses and drives the rotating cylinder (3) to rotate, so that the chassis rotates side by side, and then completes the welding of each edge in turn. Since the rotating cylinder (3) reverses during welding, the sliding table (17) will also reset to the initial position, and then the material plate is driven upward for a distance under the action of the stepping assembly to facilitate subsequent continued grabbing; Step 4: After the four sides are welded, the fourth electric push rod (57) drives the locking pin to be inserted into the locking hole (58) again to lock the hollow tube (41), and then the grab plate (15) is retracted and separated from the material plate. The right-angle positioning groove plate (29) can clamp the welded chassis, and then the moving assembly drives the U-shaped frame (8) away from the rotating cylinder (3) to remove the welded chassis from the rotating cylinder (3). After removal, the first electric push rod (7) drives the driving arm (35) to move, and the driving arm (35) drives the flip connection block (36) to flip, flipping the clamped chassis 90 degrees, and then releasing the clamping of the chassis. The chassis falls onto the conveyor (4) and is sent out by the conveyor (4) to complete the unloading of the chassis.
