The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0035] In order to improve production efficiency and contribute to the mass production of soft-pack batteries, this embodiment provides a corner folding fixture, which will be described in detail below in combination with Figures 1 to 5 the specific content of this embodiment.

[0036] The corner folding fixture in this embodiment includes a fixture base 1, a pushing module 2, and a corner folding module 3. The fixture base 1 has a positioning groove 11 for placing the soft-pack battery 100. The pushing module 2 includes a first moving member 21, which is arranged on the fixture base 1 and can move along a first direction. Two beveled portions 211 are arranged at intervals along a second direction on the first moving member 21. The corner folding module 3 includes two second moving members 31 having rollers 32. The second moving members 31 are slidably arranged on the fixture base 1. The two rollers 32 are respectively located on both sides of the soft-pack battery 100. The beveled portion 211 abuts against the corresponding second moving member 31 and can make the second moving member 31 move along the second direction.

[0037] The corner folding fixture provided by the utility model is provided with a positioning groove 11 for placing the soft-pack battery 100 on the fixture base 1, which is used to limit the position of the soft-pack battery 100 on the fixture base 1. Rollers 32 are arranged on the second moving member 31 of the corner folding module 3, and the two rollers 32 are respectively located on both sides of the soft-pack battery 100. By pushing the first moving member 21 of the pushing module 2 along the first direction, the beveled portion 211 of the first moving member 21 abuts against the second moving member 31 and causes the second moving member 31 to move along the second direction, so that the two rollers 32 approach each other simultaneously and bend the top-sealed side edge 101 of the soft-pack battery 100. Completing the corner folding action can reduce the size of the finished battery and save the space for assembling the host machine with it. By using the corner folding fixture to fold the top-sealed side edge 101 of the soft-pack battery 100, not only the production efficiency of the battery is improved, but also the mass production of the soft-pack battery 100 is facilitated.

[0038] Further, as Figure 4 shown in combination with Figure 5 In the figure, an arc portion 311 is provided on one side of each second moving member 31 close to the first moving member 21, and the arc portion 311 abuts against the corresponding beveled portion 211. By adding the arc portion 311, during the process of the beveled portion 211 pushing the second moving member 31, the stress concentration on the contact surface of the second moving member 31 is reduced.

[0039] Furthermore, the corner folding fixture further includes a reset module 4. The reset module 4 includes an elastic member 41. One end of the elastic member 41 is connected to the second moving member 31, and the other end of the elastic member 41 is connected to the fixture base 1. Under the action of the first moving member 21, the two second moving members 31 approach each other to complete the corner folding of the top-sealed side edge 101 of the soft-pack battery 100. By adding the reset module 4, the two second moving members 31 can be reset, which is convenient for repeated operation.

[0040] Optionally, the elastic member 41 includes a tension spring. A first pin 33 is provided on the second moving member 31, and a second pin 12 is provided on the fixture base 1. The hook parts at both ends of the tension spring are respectively connected to the first pin 33 and the second pin 12. As Figure 4 shown in combination with Figure 5 In the figure, a first connection hole 151 is provided on the fixture base 1, and the second pin 12 is threadedly connected to the first connection hole 151; a second connection hole is provided on the second moving member 31, and the first pin 33 is threadedly connected to the second connection hole, and the second moving member 31 is reset by using the tension spring.

[0041] Further, a first mounting groove 13 is provided on the fixture base 1. A first guide rail 14 extending in the first direction is provided on the bottom wall of the first mounting groove 13. A first slider 22 is provided at the bottom of the first moving member 21. The first slider 22 is slidably connected to the first guide rail 14. By adding the first guide rail 14 and the first slider 22, not only the moving frictional resistance of the first moving member 21 is reduced, but also the moving accuracy of the first moving member 21 is ensured.

[0042] Furthermore, a second mounting groove 15 is provided on the fixture base 1. A second guide rail 16 extending in the second direction is provided on the bottom wall of the second mounting groove 15. A second slider 34 is provided at the bottom of the second moving member 31. The second slider 34 is slidably connected to the second guide rail 16. By adding the second guide rail 16 and the second slider 34, not only the moving frictional resistance of the second moving member 31 is reduced, but also the moving accuracy of the second moving member 31 is ensured.

[0043] Further, two avoidance grooves 17 are further provided on the fixture base 1. The two avoidance grooves 17 are respectively located on both sides of the positioning groove 11, and the depth of the avoidance groove 17 is greater than the depth of the positioning groove 11. By providing the avoidance grooves 17 on both sides of the positioning groove 11, it is convenient for a person to grasp or place the soft-pack battery 100.

[0044] Optionally, the pushing module 2 further includes a handle 23. The handle 23 is provided on the first moving member 21. An operator can simply hold the handle 23 to push the first moving member 21, and the operation is simple and convenient.

[0045] Further, the folding-angle fixture further includes a limit cover plate 5. A strip-shaped limit hole 51 extending in the first direction is provided on the limit cover plate 5. One end of the handle 23 passes through the strip-shaped limit hole 51 and extends out. The limit cover plate 5 can cover the first mounting groove and the second mounting groove of the limit cover plate 5. On the one hand, it avoids the deposition of dust. On the other hand, since the strip-shaped limit hole 51 is added on the limit cover plate 5, the movable stroke range of the handle 23 is limited by the length of the strip-shaped limit hole 51.

[0046] Furthermore, an observation notch 52 is provided on one side of the limit cover plate 5 close to the positioning groove 11, which is convenient for an operator to observe the folding-angle process of the top-sealing side edge 101 of the soft-pack battery 100 by the roller 32 at any time.

[0047] In summary, the present embodiment provides a corner folding fixture for a soft-pack battery, including a longitudinal pushing module 2, a transverse corner folding module 3, and a reset module 4. Among them, the beveled portion 211 of the first moving member 21 contacts the arc-shaped portion 311 of the second moving member 31, and there is a roller 32 for corner folding on the cam mechanism. The tension spring of the reset module 4 stretches the second moving member 31 to reset it. First, pull the handle 23 to longitudinally move the first moving member 21 to the limit position, thereby driving the contacted second moving member 31 to move transversely. The roller 32 fixed on the second moving member 31 synchronously rolls on the top-sealed side edge 101 of the soft-pack battery 100 to complete the corner folding. Finally, release the handle 23, and the tension spring of the reset mechanism forces the second moving member 31 to reset, completing the entire corner folding action.
