[0042] The working principle of the present invention is: when working, the required material plates are placed in the placement grooves 18 respectively, and then the first second electric push rods 50 drive the grab plate 15 to move, so that the first grab plate 15 is attached to the material plate in the first placement groove 18, and then the corresponding pneumatic suction cup 16 is started to adsorb the material plate, and the grab plate 15 is reset after adsorption. After the grab 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 gear 20 to rotate, and the second gear 20 rotates.

Each rotation of the hollow shaft 27 can realize the switching of the position of the grab plate 15 once, and 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 table 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 table 17 will move synchronously, so that the corresponding material plate can be moved to the bottom of the grab plate 15, so as to realize the grabbing of the material plates one by one, and splice the material plates. After the splicing is completed, the moving component drives the U-shaped frame 8 to move toward the rotating cylinder 3. After reaching the set position, the telescopic component The sliding arm 9 is driven 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 of the hollow tube 41, and 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 to drive the transverse slider 32 to move. The movement of the transverse slider 32 can 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 on the current side. After the welding of the current side is completed, the fourth servo motor 23 intermittently reverses to drive the rotating cylinder 3 to rotate, so that the chassis rotates side by side, and then rotates according to the rotation of the second servo motor 34. The welding of each side is completed at the same time. Since the rotating cylinder 3 is reversed during welding, the sliding table 17 will also be reset to the initial position. Then, the material plate is driven upward for a distance under the action of the stepping assembly to facilitate the subsequent grabbing. After the welding of the four sides is completed, 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. Then the grab plate 15 is retracted and separated from the material plate. The right-angle positioning groove plate 29 can clamp the chassis formed by welding. 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. The driving arm 35 drives the flip connection block 36 to flip, flip the clamped chassis 90 degrees, and then releases 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.

10. A welding method for the automatic welding equipment for the wiring chassis according to claim 9, characterized in that: The following steps are involved: Step 1: During operation, the required material plates are placed in the placement grooves (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 groove (18), and then the corresponding pneumatic suction cup (16) is started to adsorb the material plate. After adsorption, the grabbing plate (15) is reset. 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. 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 achieve 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 table (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 table (17) will move synchronously, so that the corresponding material plate is moved to the bottom of the grab plate (15), thereby achieving 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, the first servo motor (30) then 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 to drive the transverse sliding block (32) to move, and the movement of the transverse sliding block (32) can 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 to drive the rotating cylinder (3) to rotate, so that the chassis rotates side by side, and then the welding of each edge is completed in sequence. 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 grasping; 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, and 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), and the welded chassis is removed 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, and the clamped chassis is flipped 90 degrees, and then the clamping of the chassis is released, and the chassis falls onto the conveyor (4), and is sent out by the conveyor (4) to complete the unloading of the chassis.
