The output end of the third motor 406 is fixedly connected with a universal joint group 407. The universal joint group 407 is rotatably connected to the bent frame 405. A plurality of worm gears 408 are fixedly connected to the outer wall of the universal joint group 407. Worm wheels 409 are meshed and driven on both sides of the worm gear 408. A rotating rod 410 is fixedly connected to the worm wheel 409. The bottom end of the rotating rod 410 is rotatably connected to the bent frame 405. One end of the rotating rod 410 is rotatably connected with an abutting wheel 411. A rubber layer is arranged on the outer wall of the abutting wheel 411, which has the function of protecting the inner wall of the bent busbar groove 601. The electric push rod 403 is used to drive the connecting frame 404 to move downwards, so that the bent frame 405 on the connecting frame 404 can be inserted into the inner side of the bent busbar groove 601. Then, the third motor 406 is used to drive the connected universal joint group 407 to rotate.

[0037] As shown Figure 7 in the figure, a ring rack 501 is fixedly connected to the inner wall of the lower side of the rotating seat 5. The ring rack 501 is meshed and driven with the adjusting wheel 102. A plurality of rollers 502 are rotatably connected to the lower surface of the rotating seat 5 in an annular structure.

[0038] As shown Figure 8 in the figure, a plurality of bent busbars 601 are placed on the placement rack 6. The inner wall of the bent busbar 601 abuts against the outer wall of the abutting wheel 411. A fixed limiting plate 602 is fixedly connected to one side of the placement rack 6. The fixed limiting plate 602 is adapted to one side of the bent busbar 601.

[0039] As shown Figure 8 in the figure, the automatic feeding mechanism 7 includes a reciprocating lead screw 701. The bottom end of the reciprocating lead screw 701 is rotatably connected to the placement rack 6. The top end of the reciprocating lead screw 701 is fixedly connected with a driven wheel 702. The driven wheel 702 is meshed and driven with the driving wheel 201. A moving frame 703 is slidably fitted on the outer wall of the reciprocating lead screw 701. One end of the moving frame 703 passes through the fixed limiting plate 602 and is fixedly connected with a lifting plate 704. By driving the connected electric push rod 403 to rotate clockwise with the second motor 401, the bending frame 405 is driven to move above the bent busbar 601 to be welded. At this time, the second motor 401 drives the driving wheel 201 on one side to rotate through the connected sector gear 402, so that the driving wheel 201 can drive the reciprocating lead screw 701 connected to the driven wheel 702 to rotate, and the reciprocating lead screw 701 can drive the lifting plate 704 connected to the moving frame 703 to move up by a distance equal to the height of one bent busbar 601.

[0040] As shown Figure 9 in the figure, one side of the movable limiting plate 8 is adapted to the other side of the bent busbar 601. A transmission wheel 801 is fixedly connected to the bottom end of the movable limiting plate 8. A transmission rack 802 is meshed and driven below the transmission wheel 801. A T-shaped frame 803 is fixedly connected to the transmission rack 802. One side of the T-shaped frame 803 is slidably fitted with the placement rack 6. Both ends of the other side of the T-shaped frame 803 are fixedly connected with a tension spring 804. The other end of the tension spring 804 is fixedly connected with the placement rack 6. A contact shaft 805 is rotatably connected to the lower side of the T-shaped frame 803. The outer wall of the contact shaft 805 is in sliding contact with the outer wall of the guiding ring 103. The tension spring 804 drives the T-shaped frame 803 to automatically reset. The contact shaft 805 will move out of the concave part of the guiding ring 103. At this time, the T-shaped frame 803 connected to the contact shaft 805 will be driven to move, so that the T-shaped frame 803 drives the connected transmission rack 802 to move, and the transmission rack 802 can drive the movable limiting plate 8 connected to the transmission wheel 801 to rotate and stand up.

[0041] Working principle: When welding the bent busbar 601 is required, first, the first motor 101 drives the connected adjusting wheel 102 to rotate, so that the adjusting wheel 102 drives the rotating seat 5 connected to the annular rack 501 to rotate clockwise, causing the placing rack 6 with the bent busbar 601 to be welded placed on the front side to rotate to one side. At this time, the driven wheel 702 connected to the reciprocating lead screw 701 on the placing rack 6 meshes with the driving wheel 201;

[0042] At this time, the contact shaft 805 will move out of the concave part of the guiding ring 103. At this time, it will drive the T-shaped frame 803 connected to the contact shaft 805 to move, so that the T-shaped frame 803 drives the connected transmission rack 802 to move, so that the transmission rack 802 can drive the movable limiting plate 8 connected to the transmission wheel 801 to rotate and stand up, cooperating with the fixed limiting plate 602 to limit the bent busbar 601;

[0043] Then, the second motor 401 drives the connected electric push rod 403 to rotate clockwise, thereby driving the bending frame 405 to move above the bent busbar 601 to be welded. At this time, the second motor 401 drives the driving wheel 201 on one side to rotate through the connected sector gear 402, so that the driving wheel 201 can drive the reciprocating lead screw 701 connected to the driven wheel 702 to rotate, so that the reciprocating lead screw 701 can drive the lifting plate 704 connected to the moving frame 703 to move up a distance equal to the height of one bent busbar 601;

[0044] Then, the electric push rod 403 drives the connecting frame 404 to move downwards, so that the bending frame 405 on the connecting frame 404 can be inserted into the inner side of the bent busbar 601. Then, the third motor 406 drives the connected universal joint group 407 to rotate. At this time, the universal joint group 407 drives the connected worm 408 to rotate, so that the worm 408 can drive the two side worm wheels 409 to rotate, so that the worm wheels 409 can drive the connected rotating rod 410 to rotate, so that the abutting wheel 411 on the rotating rod 410 can abut against the inner side of the bent busbar 601 to achieve clamping. Then, the electric push rod 403 drives the bending frame 405 to move up, and then the second motor 401 continues to drive the electric push rod 403 to rotate, driving the bent busbar 601 to be welded to rotate to the other side for welding;

[0045] At this time, the second motor 401 drives the driving wheel 201 on the other side to rotate through the connected sector gear 402, so that the driving wheel 201 can drive the reciprocating lead screw 701 connected to the driven wheel 702 to rotate, so that the reciprocating lead screw 701 can drive the lifting plate 704 connected to the moving frame 703 to move down a distance equal to the height of one bent busbar 601, facilitating the placement of the welded bent busbar 601.
