Description

Technical Field

[0001] The utility model relates to the technical field of new energy batteries, in particular to a clamping device for battery assembly. Background Art

[0002] Lithium battery packs are mostly composed of several round batteries. During assembly, the round batteries are generally arranged into a rectangular array according to a certain number of rows and columns based on the assembly specifications, and then the batteries are clamped and fixed before welding and assembly can be carried out.

[0003] For example, the patent with application number 202020879416.6 discloses a clamping tool for lithium battery assembly, including a bottom plate, a fixed plate installed at one end of the bottom plate, a first side plate fixed to one side of the fixed plate, a slide groove is provided on the fixed plate, a second side plate is provided on the sliding card in the slide groove, the first side plate and the second side plate are both provided with a through groove, a push plate is provided on the sliding card in the through groove, and a number of grooves for fixing lithium batteries are evenly distributed on the fixed plate; a driving mechanism for driving the push plate to translate along the through groove is also installed on the bottom plate. The second side plate in the clamping tool for lithium battery assembly can be adjusted by sliding along the slide groove, so that it is suitable for the assembly of lithium batteries with different combinations and arrangements. The push plate is driven by the driving cylinder to translate to achieve fixed clamping of the lithium battery, and the clamping effect is stable and reliable; a groove is provided on the fixed plate to limit the lithium battery to prevent it from moving or tipping over at will, thereby ensuring the stability of the assembly process.

[0004] At present, the clamping devices used in battery assembly are all directly installed on the bottom plate. Because both poles of the battery need to be welded when assembling the battery, after welding one end of the battery, it needs to be turned over and the other end is welded. However, these clamping devices cannot be directly turned over when the battery is clamped. For example, the clamping tool in the above patent can only loosen the battery and turn the battery over, and then re-clamp the battery to continue welding. The operation during welding is cumbersome. Summary of the invention

After adjusting the position of the No. 1 splint 5, the two-claw nut 8 can be screwed on the outside of the positioning screw 7. At this time, the bottom surface of the two-claw nut 8 will be in close contact with the top surface of the No. 1 splint positioning rod 6. Therefore, the position of the No. 1 splint 5 can be fixed by cooperating with the positioning screw 7 and the No. 1 splint positioning rod 6; two positioning screws 7 are provided on both sides of the top of the No. 1 splint 5. When the No. 1 splint 5 is adjusted forward and backward, the positioning screw 7 at its top will move forward and backward in the long strip groove on the No. 1 splint positioning rod 6. After adjusting the position of the No. 1 splint 5, the two-claw nut 8 can be screwed on the outside of the positioning screw 7.

[0031] In the present disclosure, Figure 1-Figure 5 As shown, an L-shaped plate is provided on the front and rear sides of the top of the battery clamping frame 2, and the battery support plate 3 can slide left and right in the guide groove between the L-shaped plate and the battery clamping frame 2. The L-shaped plates on the front and rear sides of the top of the battery clamping frame 2 can limit the battery support plate 3, avoiding the battery support plate 3 from moving up and down, and ensuring the stability of the battery support plate 3 sliding left and right.

[0032] In the present disclosure, Figure 6 As shown, the No. 1 clamping plate 5 can slide forward and backward under the support of the two No. 2 clamping plates 9, and the two No. 2 clamping plates 9 can also slide left and right under the support of the No. 1 clamping plate 5.

When the battery support plate 3 located above slides to both sides of the battery clamping frame 2, the top of the battery can be exposed, which is convenient for welding and assembly of the two poles of the battery, and at the same time, the rectangular raised plates on one side of the battery support plate 3 will be embedded in the rectangular holes on both sides of the top of the base 1, so the rotation of the battery clamping frame 2 can be limited by the battery support plate 3, while ensuring stability during welding and assembly.

[0034] In the present disclosure, Figure 1-Figure 3As shown, the adjusting screw 10 is a two-section screw, and the threads on its left and right sides are reverse threads. The two sections of threads on the outside of the adjusting screw 10 are respectively engaged with the threaded holes on the rectangular plates on the front and rear sides of the two No. 2 clamps 9. When the adjusting screw 10 rotates, it will rely on its outer threads to cooperate with the threaded holes on the rectangular plates on the front and rear sides of the No. 2 clamps 9 to drive the No. 2 clamps 9 to slide left and right under the support of the battery clamping frame 2. Moreover, because the threads on both sides of the adjusting screw 10 are reverse threads, the two No. 2 clamps 9 will slide in opposite directions synchronously, so that the two No. 2 clamps 9 can clamp or loosen the two sides of the battery.

[0035] In the present disclosure, Figure 5 As shown, the No. 1 plywood 5 can slide forward and backward under the support of the supporting guide rod 4. The No. 1 plywood positioning rod 6 is provided with a long strip groove running through from top to bottom, and the positioning screw 7 on the top of the No. 1 plywood 5 passes through the long strip groove on the No. 1 plywood positioning rod 6 and extends upward.

After adjusting the position of the No. 1 plywood 5, the two-claw nut 8 can be screwed on the outside of the positioning screw 7. At this time, the bottom surface of the two-claw nut 8 will be in close contact with the top surface of the No. 1 plywood positioning rod 6. Therefore, the position of the No. 1 plywood 5 can be fixed by cooperating with the positioning screw 7 and the No. 1 plywood positioning rod 6.

[0036] Embodiment 2, based on embodiment 1, as Figure 1-Figure 6 As shown, a hexagonal column can be set at both ends of the adjusting screw rod 10. When the second clamp plate 9 needs to be adjusted, the hexagonal columns at both ends of the adjusting screw rod 10 can be used to drive it to rotate, which makes it more convenient and labor-saving to rotate the adjusting screw rod 10.

[0037] Working principle of this embodiment: When it is necessary to use this device to clamp the battery for welding, first push the two battery support plates 3 below the battery clamping frame 2 to the middle position, and push the two battery support plates 3 above the battery clamping frame 2 to the left and right sides respectively. At this time, the rectangular raised plates on one side of the two battery support plates 3 will be embedded in the rectangular holes on both sides of the top of the base 1, so the rotation of the battery clamping frame 2 can be restricted by the battery support plates 3. Then, the round batteries to be assembled can be placed on the inner side of the battery clamping frame 2, the first clamping plate 5 and the second clamping plate. 9, at this time, the battery support plate 3 below will support the round battery to prevent the battery from falling down. After the battery is placed, the hexagonal columns at both ends of the adjusting screw rod 10 can be used to drive it to rotate. When the adjusting screw rod 10 rotates, it will rely on its outer thread to cooperate with the threaded holes on the front and rear rectangular plates of the second clamping plate 9 to drive the second clamping plate 9 to slide left and right under the support of the battery clamping frame 2. Moreover, because the threads on both sides of the adjusting screw rod 10 are reverse threads, the two second clamping plates 9 will slide in the opposite direction synchronously, so that The two No. 2 clamping plates 9 clamp the two sides of the battery, and then loosen the two-claw nut 8 on the positioning screw 7, and then push the No. 1 clamping plate 5 to slide forward under the support of the supporting guide rod 4 to tighten the rear side of the battery. After adjusting the position of the No. 1 clamping plate 5, the two-claw nut 8 can be screwed on the outside of the positioning screw 7. At this time, the bottom surface of the two-claw nut 8 will be in close contact with the top surface of the No. 1 clamping plate positioning rod 6, so the position of the No. 1 clamping plate 5 can be fixed by the positioning screw 7 and the No. 1 clamping plate positioning rod 6. At this time, the battery clamping frame 2 can be aligned with the No. 1 clamping plate 5 and the No. 2 clamping plate. The clamping plates 9 cooperate to clamp and fix the battery, and then the electrodes on the top of the battery can be welded and assembled first. After the electrodes on the top of the battery are welded and assembled, the two battery support plates 3 above the battery clamping frame 2 are pushed to the middle position, and then the battery clamping frame 2 can be rotated 180° under the support of the base 1. At this time, the unwelded end of the battery will be rotated to the top, and then the battery support plate 3 located at the top at this time can be pushed to the left and right sides to lock the battery clamping frame 2 again, and then the electrodes at the other end of the battery can be welded and assembled;

[0038] After the battery is welded and assembled, it is only necessary to rotate the adjusting screw rod 10 in the opposite direction to loosen the left and right sides of the battery by the second clamping plate 9, and then loosen the second claw nut 8 and push the first clamping plate 5 backwards, so that the welded and assembled battery pack can be taken out.
