Figures 1 to 7A battery cover welding tool shown in the figure includes: a workbench 3 and a rotary clamping mechanism 4, a processing station and two limit blocks 5 are provided on the workbench 3, the two limit blocks 5 are arranged on both sides of the processing station and the spacing is adjustable, the rotary clamping mechanism 4 is arranged on the workbench 3, the rotary clamping mechanism 4 includes a rotating rod 41 and a clamping block 42, the clamping block 42 is arranged at the end of the rotating rod 41, and a welding hole 43 is opened on the clamping block 42, and the rotary clamping mechanism 4 is configured to press the workpiece on the processing station onto the workbench 3.

[0031] For example, in the embodiment of the utility model, the tool is used to weld the cover plate 1 and the connecting piece 2. The processing station is any position on the workbench 3. The cover plate 1 is placed on the processing station, and the connecting piece 2 is set on the cover plate 1. By controlling the two limit blocks 5, the two sides of the cover plate 1 are clamped and fixed. The rotating rod 41 is vertically arranged on the workbench 3.

Figure 1 As shown in FIG. 1 , it is a schematic diagram of the overall structure of the tooling during the installation stage. The rotary clamping mechanism 4 is located on one side of the cover plate 1 in the initial state. Figure 2 As shown, it is a schematic diagram of the overall structure of the tooling in the welding stage. When welding work is required, the motor controls the rotating rod 41 to rotate 90 degrees, so that the clamping block 42 is located directly above the connecting piece 2 and the cover plate 1, and the motor then controls the rotating rod 41 to descend, so that the clamping block 42 presses the connecting piece 2 and the cover plate 1 on the workbench 3, and the welding hole 43 matches the welding point area between the connecting piece 2 and the cover plate 1. The laser welds the connecting piece 2 and the cover plate 1 through the welding hole 43. After welding is completed, the motor controls the rotating rod 41 to return to the initial state position.

[0032] The embodiment of the utility model provides a battery cover plate welding tool, by arranging limit blocks 5 on both sides of the cover plate 1, the limit blocks 5 are arranged at intervals and the spacing is adjustable, so that cover plates 1 of different sizes can be clamped and fixed on the workbench 3 by two limit blocks 5, and then the connecting piece 2 and the cover plate 1 are pressed on the workbench 3 from above by a rotating clamping mechanism 4, and the connecting piece 2 and the cover plate 1 are welded through welding holes 43, so that the welding of cover plates 1 and connecting pieces 2 of different sizes can be realized on the workbench 3, which can effectively solve the problem of low compatibility of battery cover plate welding tooling in the prior art.

[0033] Optionally, a V-shaped groove 51 is formed on one side of the two limit blocks 5 that are close to each other.

[0034] For example, in the embodiment of the present utility model, Figure 6As shown, the tool is suitable for cylindrical batteries. Since the cover plate 1 is circular, a V-shaped groove 51 is provided on the side of the limit block 5 close to the cover plate 1, so that the limit block 5 can be more evenly stressed when clamping and fixing the cover plate 1. The circular cover plate 1 can be completely clamped in the two V-shaped grooves 51, so that the cover plate 1 is more firmly fixed on the workbench in the horizontal direction, thereby improving the stability of the battery cover plate welding tool.

[0035] Optionally, a first mounting hole 52 is formed on the limiting block 5 , and a second mounting hole 31 matching the first mounting hole 52 is formed on the workbench 3 . A plurality of second mounting holes 31 are arranged at intervals along the sliding direction of the limiting block 5 .

[0036] For example, in the embodiment of the utility model, the first mounting hole 52 and the second mounting hole 31 cooperate to fix the limit block 5 after clamping the cover plate 1, thereby preventing the limit block 5 from being displaced during welding, thereby ensuring the welding accuracy and improving the stability of the battery cover welding tool. By providing a plurality of second mounting holes 31, the limit block 5 can be fixed at different positions when processing cover plates 1 of different sizes, thereby improving the compatibility of the battery cover welding tool.

[0037] Optionally, the first mounting hole 52 is a bar-shaped hole.

[0038] Illustratively, in an embodiment of the utility model, the length direction of the strip hole is consistent with the sliding direction of the limit block 5. By setting the first mounting hole 52 as a strip hole, when the limit block 5 and the workbench 3 need to be fixed between the two second mounting holes 31, the matching position of the first mounting hole 52 and the second mounting hole 31 can be moved so that the limit block 5 can be fixed at any position along its sliding direction, thereby further improving the compatibility of the battery cover welding tooling.

[0039] Optionally, a strip push block 6 is further included. A pole hole 32 is opened on the workbench 3. Slide grooves 33 arranged along the sliding direction of the limit block 5 are opened on both sides of the pole hole 32. The strip push block 6 can be slidably set in the slide groove 33.

[0040] For example, in the embodiment of the present utility model, a pole 11 is also included, such as Figure 1 and Figure 7As shown, in the welding process, the cover plate 1 and the pole 11 are usually fixed into an integral structure. By opening a pole hole 32 on the workbench 3, when the cover plate 1 is placed on the workbench 3, the pole 11 can be extended to the bottom of the workbench 3 through the pole hole 32, and the cover plate 1 is placed on the table top of the workbench 3. The pole hole 32 plays a certain limiting role in placing the cover plate 1 on the workbench 3. During the welding preparation process, it is convenient for the operator to place the cover plate 1 in a suitable processing area. The limit block 5 slides on the table top of the workbench 3, and a slide groove 33 is opened on the table top of the workbench 3, so that the strip push block 6 slides under the limit block 5. After placing the cover plate 1 and the pole 11, the limit block 5 is controlled to move so that the two limit blocks 5 clamp and fix the cover plate 1, and then the limit block 5 is fixed on the workbench 3, and then the strip push block 6 is pushed in the slide groove 33 so that the ends of the two strip push blocks 6 clamp the pole 11, and then the strip push block 6 is fixed to the limit block 5, so that the strip push block 6 is fixed on the workbench 3. With this structure, the overall structure of the cover plate 1 and the pole 11 is more firmly fixed on the workbench, further improving the stability of the battery cover welding tooling.

[0041] Optionally, a third mounting hole 53 is formed on the limiting block 5 , and a fourth mounting hole 61 matching the third mounting hole 53 is formed on the strip-shaped push block 6 , and a plurality of fourth mounting holes 61 are arranged at intervals along the sliding direction of the limiting block 5 .

[0042] Illustratively, in an embodiment of the utility model, the limit block 5 and the strip push block 6 are fixed by means of a third mounting hole 53 and a fourth mounting hole 61. By providing a plurality of fourth mounting holes 61, the strip push block 6 can be fixed to the limit block 5 at different positions, so that the position of the strip push block 6 can be adjusted to clamp poles 11 of different sizes, thereby further improving the compatibility of the battery cover welding tooling.

[0043] Optionally, the third mounting hole 53 is a bar-shaped hole.

[0044] Exemplarily, in an embodiment of the utility model, the length direction of the strip hole is consistent with the sliding direction of the limit block 5. By setting the third mounting hole 53 as a strip hole, when the limit block 5 needs to be fixed with the strip push block 6 between the two fourth mounting holes 61, the matching position of the third mounting hole 53 and the fourth mounting hole 61 can be moved so that the strip push block 6 can be fixed at any position along its sliding direction, thereby adapting to poles 11 of all sizes, further improving the compatibility of the battery cover welding tooling.

[0045] Optionally, a sliding block 7 is further included. The sliding block 7 is mounted on one side limit block 5 , and the sliding block 7 is slidably arranged on the workbench 3 along the sliding direction of the limit block 5 .

The welding sheet 21 is arranged on the top of the cover plate 1, the top sheet 23 is arranged on the top of the sliding block 7, and the folding sheet 22 is used to connect the welding sheet 21 and the top sheet 23. Figure 1 and Figure 5 As shown, the connecting sheet 2 is a structure composed of a welding sheet 21, a folding sheet 22 and a top sheet 23. After the welding sheet 21 is welded to the cover plate 1, the top sheet 23 is located above the welding sheet 21 by bending the two sides of the folding sheet 22, and then the top sheet 23 is connected to the external device for charging and discharging. By providing a sliding block 7, a mounting groove matching the top sheet 23 is provided on the sliding block 7, so that the top sheet 23 is installed in the mounting groove on the top of the sliding block 7, and the sliding block 7 supports the top sheet 23. At the same time, the sliding block 7 can be slidably arranged on the workbench 3 along the sliding direction of the limit block 5, so as to adapt to connecting sheets 2 of different models and sizes, so that the connecting sheet 2 is more stably arranged on the workbench 3, so that the welding sheet 21 is more stably arranged on the cover plate 1. Thereby, the stability of the battery cover welding tooling is further improved.

[0048] Illustratively, in an embodiment of the utility model, the sliding block 7 is fixed on the workbench 3 by the cooperation of the fifth mounting hole 71 and the sixth mounting hole 34. By setting the fifth mounting hole 71 and the sixth mounting hole 34, the sliding block 7 can be fixed after the connecting plate 2 is installed to prevent the sliding block 7 and the connecting plate 2 from being displaced during the welding process. At the same time, multiple sixth mounting holes 34 are provided to facilitate the fixing of the sliding block 7 at different positions when installing connecting plates 2 of different sizes, thereby further improving the compatibility of the battery cover welding tooling.
