Since the hard copper busbar is usually used for conductive connection, its processing accuracy and consistency are crucial to the electrical performance.

The copper bar limiting device is used for limiting a copper bar, and comprises: a base block and two clamping arms, which are symmetrically arranged on the base block. The clamping arm comprises a connecting portion, an inclined portion and a supporting portion connected in sequence from bottom to top. The connecting portion is connected to the base block, the inclined portion is inclined toward the direction of the clamping arm opposite thereto, and a buffer area for installing the copper bar is formed between the two inclined portions. The supporting portion is arranged above the buffer area. When the copper bar is arranged between the two clamping arms, the supporting portion is arranged to abut against the outer wall of the copper bar. In this way, the patent improves the welding quality and welding efficiency of the copper bar.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 7One embodiment of the present invention is: a limiting device for copper busbar manufacturing, comprising a base 1, a supporting electrode 2 is fixedly installed on the top of the base 1, and also comprises a limiting device; wherein the limiting device comprises a fixing frame 3, a lifting plate 4, a convex tube 5, a roller 6 and a cylindrical rod 7, the fixing frame 3 is fixedly installed on the top of the base 1, the lifting plate 4 slides through the top of the fixing frame 3, the convex tube 5 is fixedly installed on the inner wall of the lifting plate 4, the roller 6 is rotatably installed on the circumferential surface of the convex tube 5, the cylindrical rod 7 is fixedly installed on the surface of the lifting plate 4, a through groove is opened inside the fixing frame 3, and the circumferential surface of the cylindrical rod 7 contacts the inner wall of the through groove. By setting a slidable lifting plate 4, the operator can quickly adjust the height of the hard copper busbar according to different welding requirements, and ensure that the hard copper busbar will not deflect during the adjustment.

[0021] A T-shaped rod 8 slides through the top of the convex tube 5, a spring 9 is arranged between the T-shaped rod 8 and the convex tube 5, a T-shaped plate 10 is fixedly installed on the top of the T-shaped rod 8, and a contact plate 11 is fixedly installed on the bottom of the T-shaped plate 10. The contact plate 11 can be automatically adjusted according to the thickness of the hard copper busbar and a stable pressure is applied downward, thereby effectively improving the quality of welding.

[0022] The T-shaped plate 10 contacts the top of the convex tube 5, and arc surfaces are provided on both sides of the bottom of the contact plate 11. The convex tube 5 provides support for the T-shaped plate 10, so that the T-shaped plate 10 is effectively supported in the initial position.

[0023] When the present embodiment is working, the first hard copper bar is controlled to pass through the lifting plate 4, and the hard copper bar contacts the top of the lifting plate 4 during movement. The lifting plate 4 provides support for the hard copper bar, and at the same time, the outer wall of the hard copper bar contacts the circumferential surface of the two rollers 6, so that the hard copper bar moves and drives the two rollers 6 to rotate, and the two rollers 6 cooperate to limit the moving direction of the hard copper bar, ensuring that the hard copper bar maintains a straight path during movement. At the same time, the top of the hard copper bar contacts the arc surface 1 of the contact plate 11 during movement, and the hard copper bar moves to squeeze the arc surface 1, and the contact plate 11 is squeezed and moves upward, and the contact plate 11 moves and drives The T-shaped plate 10 moves upward, and the movement of the T-shaped plate 10 drives the T-shaped rod 8 to move upward. The T-shaped rod 8 moves and stretches the spring 9. The spring 9 applies a reaction force to the T-shaped rod 8 during the deformation process, so that the contact plate 11 applies pressure to the hard copper bar passing below to ensure that the hard copper bar remains stable during the welding process. When the first hard copper bar contacts the top of the supporting electrode 2, the operator repeats the above operation, controls the second hard copper bar to move from the other side to contact the top of the supporting electrode 2, and then adjusts the positions of the two hard copper bars so that the ends of the two hard copper bars contact each other, and then performs the welding operation. The roller 6 is used to rotate the hard copper bar. The moving direction of the hard copper bar is limited to ensure that the ports of the hard copper bar can be accurately aligned. At the same time, the contact plate 11 can be automatically adjusted according to the thickness of the hard copper bar and exert a stable pressure downward to effectively improve the quality of welding. When the hard copper bar is tower welded, the first hard copper bar is first controlled to contact the supporting electrode 2, and then after the second hard copper bar passes through the lifting plate 4, the lifting plate 4 is manually controlled to move upward, and the lifting plate 4 moves to drive the cylindrical rod 7 to move upward, and at the same time, the lifting plate 4 moves to drive the convex tube 5 to move upward, and the convex tube 5 moves to drive the roller 6 and the T-shaped rod 8 to move upward, and the T-shaped rod 8 moves to drive The T-shaped plate 10 moves upward, and the movement of the T-shaped plate 10 drives the contact plate 11 to move upward, thereby driving the second hard copper bar to move upward. When the lifting plate 4 moves to the predetermined position, it pushes the second hard copper bar to move toward the supporting electrode 2. The second hard copper bar contacts the top of the first hard copper bar during the movement. The positions of the two hard copper bars are adjusted to ensure that the overlapping parts are aligned before performing tower welding. By setting a slidable lifting plate 4, the operator can quickly adjust the height of the hard copper bar according to different welding requirements and ensure that the hard copper bar will not deflect during the adjustment, thereby improving the convenience of operation.

[0024] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device for improving the stability of the lifting plate 4 is provided inside the fixing frame 3, and a protective device for improving the reset safety is provided on the stabilizing device; the stabilizing device includes a carrying box 121, a sliding plate 122, a hollow tube 123, a rubber plate 124, a spring 125, a triangular plate 126 and a rectangular plate 127, the carrying box 121 is fixedly installed inside the fixing frame 3, the sliding plate 122 slides through the inner wall of the carrying box 121, and the hollow tube 123 is fixedly installed at the far end of the sliding plate 122. On the side away from the carrying box 121, the rubber plate 124 slides through the inner and outer walls of the carrying box 121, the spring piece 125 is arranged between the rubber plate 124 and the carrying box 121, the triangular plate 126 is fixedly installed on the bottom of the rubber plate 124, and the rectangular plate 127 is fixedly installed on the circumferential surface of the hollow tube 123. The inner wall of the hollow tube 123 contacts the circumferential surface of the cylindrical rod 7. The synergistic effect of the hollow tube 123 and the sliding plate 122 provides additional supporting force for the cylindrical rod 7, effectively reducing the shaking of the lifting plate 4 during movement, thereby ensuring the smooth progress of the tower connection operation.

[0025] The rubber plate 124 has a corrugated groove on one side away from the spring piece 125, and the rectangular plate 127 has an arc surface 2 on one side away from the hollow tube 123. The corrugated groove of the rubber plate 124 is in close contact with the hollow tube 123 to ensure that the hard copper busbar located at a high position remains stable during the tower welding process.

[0026] The protective device includes a C-shaped frame 131, a buffer block 132, a Z-shaped piece 133, a connecting frame 134, a fixed rod 135, a rotating piece 136 and a bottom plate 137. The C-shaped frame 131 is fixedly installed on a side of the carrying box 121 close to the cylindrical rod 7, the buffer block 132 slides through the inner and outer walls of the C-shaped frame 131, the Z-shaped piece 133 is arranged between the buffer block 132 and the C-shaped frame 131, the connecting frame 134 is fixedly installed on the surface of the C-shaped frame 131, the fixed rod 135 is fixedly installed on the inner wall of the connecting frame 134, the rotating piece 136 is rotatably installed on the circumferential surface of the fixed rod 135, and the bottom plate 137 is fixedly installed on the bottom of the connecting frame 134. The top of the buffer block 132 contacts the rectangular plate 127, and the buffer block 132 applies thrust or resistance according to the moving direction of the rectangular plate 127, which not only ensures that the rectangular plate 127 can move upward smoothly, but also prevents the sliding plate 122 from colliding when it is reset.

[0027] The Z-shaped piece 133 itself is elastic, and a torsion spring is provided between the rotating piece 136 and the fixing rod 135. By providing the torsion spring, it is ensured that the rotating piece 136 can be smoothly reset to the initial position after rotation.

[0028] The shape of the rotating piece 136 is set to be a "J" shape, and a third arc surface is opened on a side of the bottom plate 137 close to the rotating piece 136, and the third arc surface contacts the curved surface of the rotating piece 136. By setting the rotating piece 136 with elasticity, intermittent resistance is applied to the rectangular plate 127 in the resetting process, thereby effectively controlling the resetting speed of the rectangular plate 127.

[0029] When the present embodiment is working, when the hard copper bar is connected to the tower, the cylindrical rod 7 moves to drive the hollow tube 123 to move upward, and the hollow tube 123 moves to drive the rectangular plate 127 to move upward. At the same time, the hollow tube 123 moves to drive the sliding plate 122 to move upward. When the sliding plate 122 moves, the carrying box 121 provides the necessary supporting force for the sliding plate 122, so that the sliding plate 122 provides additional supporting force for the cylindrical rod 7 through the hollow tube 123. The cylindrical rod 7 moves more smoothly under the action of the additional supporting force, thereby ensuring that the lifting plate 4 is more stable during the movement. The synergistic effect of the hollow tube 123 and the sliding plate 122 provides additional supporting force for the cylindrical rod 7, effectively reducing the shaking of the lifting plate 4 during movement, thereby ensuring the smooth progress of the tower connection operation. The circumferential surface of the hollow tube 123 moves The hollow tube 123 moves and squeezes the triangular plate 126, and the triangular plate 126 is squeezed and moves in the direction of the spring sheet 125. At the same time, the movement of the triangular plate 126 drives the rubber plate 124 to move in the direction of the spring sheet 125. The rubber plate 124 squeezes the spring sheet 125 during movement, and the deformed spring sheet 125 exerts a reaction force on the rubber plate 124, so that the corrugated groove of the rubber plate 124 is in close contact with the circumferential surface of the hollow tube 123, and a clamping force is exerted on the hollow tube 123 under the influence of the reaction force, so that the hollow tube 123 moved to the designated area can remain stable, and the corrugated groove of the rubber plate 124 is in close contact with the hollow tube 123, so as to ensure that the hard copper bar located at a high place remains stable during the tower welding process, and prevent the quality of welding from being reduced due to shaking or displacement; When the rectangular plate 127 moves upward, the pressure on the buffer block 132 gradually decreases, so that the deformed Z-shaped piece 133 recovers and drives the buffer block 132 to move upward. The movement of the buffer block 132 exerts an upward thrust on the bottom of the rectangular plate 127. Under the action of the additional thrust, the rectangular plate 127 moves more smoothly. After the Z-shaped piece 133 is completely restored, the buffer block 132 stops moving, while the rectangular plate 127 continues to move and separates from the surface in contact with the buffer block 132. When the rectangular plate 127 is reset, the rectangular plate 127 moves downward. The top of the buffer block 132 is moved to contact with the rectangular plate 127, so that the rectangular plate 127 moves to drive the buffer block 132 to move downward, and the buffer block 132 moves to squeeze the Z-shaped piece 133. The deformed Z-shaped piece 133 applies a reaction force to the buffer block 132, so that the buffer block 132 slows down the speed of the rectangular plate 127 moving downward. The buffer block 132 applies a thrust or resistance according to the moving direction of the rectangular plate 127, which not only ensures that the rectangular plate 127 can move upward smoothly, but also prevents the sliding plate 122 from colliding when it is reset. The arc surface 2 of the bottom plate 137 contacts the curved surface of the rotating piece 136 during movement, so that the rectangular plate 127 moves and drives the rotating piece 136 to rotate upward. The rotating piece 136 stretches the torsion spring during rotation. At the same time, the rotating piece 136 rotates and separates from the arc surface 3 of the bottom plate 137. When the rectangular plate 127 separates from the rotating piece 136, the deformed torsion spring recovers and drives the rotating piece 136 to reset. When the rectangular plate 127 resets, the arc surface 2 moves downward and contacts the inner concave surface of the rotating piece 136, so that the rectangular plate 127 continues to move and squeeze the rotating piece 136. The rotating piece 136 is deformed due to being squeezed, and the deformed rotating piece 136 applies additional resistance to the contacting rectangular plate 127. The moving speed of the rectangular plate 127 is effectively controlled by the additional resistance. When the rectangular plate 127 is separated from the rotating piece 136, the deformed rotating piece 136 quickly recovers under the action of its own elasticity. By providing the rotating piece 136 with elasticity, intermittent resistance is applied to the rectangular plate 127 in the process of resetting, so the resetting speed of the rectangular plate 127 is effectively controlled, thereby improving the protective effect.
