When the special device for welding the cathode plate is used, firstly, the cathode plate 5 to be welded is placed on the sliding bracket 4 positioned at the welding side; then, the slide carriage 4 and the cathode plate 5 to be welded disposed thereon are moved on the glidepath 2 on the welding side at a constant speed by friction driving of the driving friction roller 32 and the driven friction roller 33 of the welding guide mechanism 9. While the cathode plate 5 to be welded moves, the gas shielded welding is performed on one surface of the outside of the joint of the cathode bottom plate and the cathode conductive cross beam by using the fixed welding gun 18. After one side of the cathode plate 5 to be welded is welded, the sliding bracket 4 and the cathode plate 5 to be welded arranged on the sliding bracket are slid onto the sliding guide rail 23 of the first rotating guide frame 3 along the welding straight rail 15 of the lower slide rail 2 and the upper slide rail 8 of the welding side. The electromagnetic switch 22 is stepped on by a foot to power off the positioning electromagnet 21, so that the sliding guide rail 23 of the first rotating guide frame 3 is separated from the lower slide rail 2 on the welding side. The first rotary guide frame 3 is rotated to the turnover side of the main body frame 1, and then the sliding guide rail 23 of the first rotary guide frame 3 is butted with the glide slope 2 of the turnover side; subsequently, the slide bracket 4 and the cathode plate 5 to be welded disposed thereon are slid onto the turn-down side glide slope 2 from the first rotating guide frame 3 along the slide guide rail 23 and the turn-down ramp 14 of the upper slide 8.

After that, the slide bracket 4 and the cathode plate 5 to be welded arranged thereon are pushed to slide to the lower part of the lifting clamping jaw 44 of the lifting turnover mechanism 6 positioned at the middle along the lower slide way 2 at the turnover side and the turnover inclined rail 14 of the upper slide way 8. Because the middle part of the intersection of the two sections of the inclined rails arranged in the V shape of the upper slide way 8 turn-over inclined rail 14 is a lifting high point, when the sliding bracket 4 slides to the middle part of the inclined rail along the upper slide way 8 turn-over inclined rail 14, the sliding bracket 4 and the cathode plate 5 to be welded arranged on the sliding bracket 4 are close to vertical, so that the clamping of the lifting clamping jaw 44 is facilitated (as shown in fig. 23). The lifting control rod 37 of the lifting turnover mechanism 6 swings upwards, and drives the turnover rotating rod 42 and the lifting clamping jaw 44 at the lower end of the turnover rotating rod to descend to the upper edge of the cathode plate 5 to be welded through the driving connecting rod 38 and the hinging connecting rod 40. Then, the jaw control rod 36 is swung downwards, and the lifting frame 43 sleeved on the turn-over rotating rod 42 is pulled to ascend by the lifting steel wire 39; and the first jaw 45 and the second jaw 46 of the lifting jaw 44 are actuated to open by the elevation of the jaw hinge shaft 77 of the lifting frame 43. When the opened lifting claw 44 is aligned with the clamping portion (the insulating strip flange) of the upper end portion of the cathode plate 5 to be welded, the claw control lever 36 is released, and the lifting claw 44 pulls the lifting frame 43 downward by gravity, so that the first claw 45 and the second claw 46 of the lifting claw 44 are closed to clamp the cathode plate 5 to be welded.

After the lifting clamping jaw 44 clamps the cathode plate 5 to be welded, the lifting control rod 37 is swung downwards to drive the turning rotating rod 42 and the cathode plate 5 to be welded clamped by the lifting clamping jaw 44 at the lower end of the turning rotating rod to ascend together, so that the cathode plate 5 to be welded is separated from the sliding bracket 4; then, the lifting frame 35 of the lifting and turning mechanism 6 slides along the sliding beam 12 at the upper part of the middle supporting frame 7 in a direction away from the main body frame 1, so that the cathode plate 5 to be welded is separated from the side part of the main body frame 1 by a certain distance, and the turning of the cathode plate is prepared. The suspended cathode plate 5 to be welded, the lifting clamping jaw 44 on the upper part of the suspended cathode plate and the tripod 76 of the lifting frame 43 are driven to rotate around the rotating shaft of the turning rotating rod 42 rotating the connector 74, so that the surface of the cathode plate 5 to be welded, which is not welded, is rotated to the outside. After the cathode plate 5 to be welded rotates in place, the lifting frame 35 of the lifting turnover mechanism 6 slides towards the direction close to the main body frame 1, so that the cathode plate 5 to be welded moves back to the position above the sliding bracket 4; the lifting control rod 37 is swung upwards to enable the turned cathode plate 5 to be welded to fall back onto the sliding bracket 4, and then the clamping jaw control rod 36 is swung downwards to enable the first clamping jaw 45 and the second clamping jaw 46 of the lifting clamping jaw 44 to be opened, so that the cathode plate 5 to be welded is separated from the lifting clamping jaw 44.

Pushing the slide bracket 4 and the cathode plate 5 to be welded which has been turned over thereon, along the lower slide way 2 on the turned-over side and the turning-over ramp 14 of the upper slide way 8, slides onto the slide rail 23 of the second rotating guide frame 10. Then, the second rotating guide 10 is rotated to the welding side of the main body frame 1, and the slide rail 23 of the second rotating guide 10 is abutted against the lower slide 2 of the welding side. After that, the slide bracket 4 and the cathode plate 5 to be welded turned over thereon are slid onto the welding-side glide slope 2 from the second rotating guide frame 10 along the slide guide rail 23 and the welding straight rail 15 of the upper slope 8. The welding guide mechanism 9 drives the sliding bracket 4 and the turned cathode plate 5 to be welded to move at a constant speed again, and the fixed welding gun 18 is utilized to weld the other surface of the joint part of the cathode bottom plate and the cathode conductive cross beam; realizing the double-sided welding of the cathode plate. The application of the special device for welding the cathode plate can reduce the number of operators, reduce the labor intensity of workers and improve the operation efficiency; in addition, the abrasion of the wire feeding pipe can be avoided, the replacement cost is reduced, and the welding quality is improved.
