Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a battery cell module assembly tooling. Background Technology

[0002] A pouch cell module consists of several pouch cells and has a large battery capacity, providing ample energy for electrical devices. During assembly, several pouch cells are arranged along the thickness direction on a fixture. Existing cell assembly fixtures typically include a support plate and baffles connected to both ends of the support plate. The stacked pouch cells are clamped between two sets of baffles, which hold the stacked pouch cells together to prevent them from loosening during busbar installation, welding, and other processes, thus ensuring the assembly of the pouch cell module.

[0003] However, current cell assembly fixtures are only capable of assembling a specified number of pouch cells. To accommodate smaller quantities of pouch cells, different sized fixtures are required, increasing costs and making the process expensive. Furthermore, existing adjustable-size module fixtures are complex and still fail to address the high cost issue. Therefore, a new cell module assembly fixture is urgently needed to solve the problems of current technologies. Utility Model Content

[0027] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0028] Currently, existing battery cell fixtures include a support plate 1 and baffles 2 connected to both ends of the support plate 1. Stacked battery cells are clamped between the two baffles 2, which hold the stacked pouch cells in place, thus preventing them from loosening during busbar installation, welding, and other processes, which would affect the assembly process of the battery cell module 100. However, the current battery cell fixtures are only large enough to assemble a limited number of battery cells. When the number of battery cells changes, different sizes of fixtures are required, which is expensive. In addition, while existing adjustable-size module fixtures can adjust the clamping space according to the size of the battery cell module 100, their complex structure leads to high costs.

[0029] To address a series of problems existing in the prior art, this embodiment provides a battery cell module assembly fixture, which aims to adapt to the assembly requirements of battery cell modules 100 of different sizes and specifications, while simplifying the structure, reducing manufacturing costs, and thus effectively improving the cost-effectiveness of use.

[0030] Combination Figures 1 to 2As shown, the battery cell module assembly fixture provided in this embodiment includes a support plate 1, baffles 2, and an adjustment assembly 3. The baffles 2 are connected to both ends of the support plate 1; the adjustment assembly 3 is disposed between the two baffles 2, and the adjustment assembly 3 abuts against one of the baffles 2 and is spaced apart from the other baffle 2, thereby forming a accommodating space capable of accommodating stacked battery cells. The stacking direction of the battery cells is the same as the distribution direction of the two baffles 2 (see reference). Figure 1 (As shown by the double-headed arrow on the X-axis), in this embodiment, the battery cell is a pouch cell. Furthermore, the adjustment component 3 can extend and retract along the stacking direction of the battery cells to adjust the distance between the adjustment component 3 and one of the baffles 2, thereby adjusting the size of the accommodating space according to the stacking thickness of the battery cells.

[0031] With the above settings, the tooling can be adapted to the assembly and assembly of different numbers of pouch cells, and there is no need to replace or discard the existing cell tooling. It is only necessary to add an adjustment component 3 directly to the existing cell tooling. The structure is simple and effectively reduces the manufacturing cost of the cell module assembly tooling provided in this embodiment.

[0032] refer to Figure 2 As shown, in this embodiment, the adjustment component 3 includes a first abutment plate 31, a second abutment plate 32, a connecting frame 33, and a sliding box 34. The first abutment plate 31 is connected to the sliding box 34 and is connected to one of the baffles 2. The second abutment plate 32 is connected to the connecting frame 33, and is positioned opposite and spaced apart from the other baffle 2, defining the aforementioned accommodating space between them. The connecting frame 33 is slidably connected to the sliding box 34 along the stacking direction, allowing the second abutment plate 32 to extend or retract relative to the first abutment plate 31. This enables adjustment of the accommodating space size according to the stacking thickness of the battery cells, providing convenient operation and a simple structure.

[0033] Specifically, the connecting frame 33 includes a first slide 331 and a second slide 332 arranged side-by-side and spaced apart along the vertical direction. The sliding box 34 is inserted into and slidably connected between the first slide 331 and the second slide 332. During the relative sliding process between the sliding box 34 and the connecting frame 33, the first slide 331 and the second slide 332 can stably fit against the upper and lower sides of the sliding box 34, thereby ensuring that the second abutment 32 remains parallel to the other baffle 2 after extension and retraction. This ensures that the width of the accommodating space is consistent throughout the vertical direction, guaranteeing the abutment effect on the battery cell module 100. In addition, the sliding box 34 and the connecting frame 33 are easy to insert, remove, and assemble, which helps improve the efficiency of maintenance personnel in repairing and replacing the connecting frame 33 and the sliding box 34, and reduces the difficulty of operation.

[0034] Optionally, the battery cell module assembly fixture also includes a connector that passes through the fixed connecting frame 33 and the slide box 34, thereby achieving relative fixation between the connecting frame 33 and the slide box 34, and thus achieving relative fixation of the positions of the first abutment 31 and the second abutment 32, ensuring the clamping effect on the battery cell module 100.

[0035] For example, in this embodiment, reference is made to Figure 2 As shown, the connector is a threaded component, including a screw and a nut. The first slide 331 is located above the second slide 332. In one embodiment, a first through hole 3311 is provided on the first slide 331, and a second through hole 341 is provided on the upper side of the slide box 34. When the connecting frame 33 slides relative to the slide box 34 and moves to the position where the first through hole 3311 is coaxially disposed with the second through hole 341, the screw passes through both the first through hole 3311 and the second through hole 341 simultaneously, and then is threadedly connected to the nut, so as to achieve relative fixation of the connecting frame 33 and the slide box 34 in the horizontal direction through the screw and the nut.

[0036] Furthermore, in this embodiment, the length direction of the first through hole 3311 on the slide box 34 is parallel to the stacking direction, so as to form a groove-shaped second through hole 341 on the slide box 34. When it is necessary to adjust the relative distance between the first abutment plate 31 and the second abutment plate 32, the screw can be moved in the second through hole 341 by loosening the nut. The second through hole 341 can guide the displacement of the screw, so that the screw and nut do not need to be completely removed, thereby facilitating the operation of adjusting the position of the first abutment plate 31 and the second abutment plate 32.

[0037] In other alternative embodiments of this embodiment, the first through hole 3311 described above can also be provided on the second slide 332, and the second through hole 341 with a groove-shaped structure described above can be provided on both the upper and lower sides of the slide box 34. In this way, by fixing the first slide 331 and the second slide 332 on the slide box 34 at the same time, the limiting and fixing effect of the connecting frame 33 and the slide box 34 is further strengthened, and the clamping performance of the tooling on the battery cell module 100 is further enhanced.

[0038] It should be noted that in other parallel embodiments, the connector only includes a screw, the first slide 331 is provided with a first through hole 3311, the upper surface of the slide box 34 is provided with a second through hole 341, and a threaded hole is provided on the support plate 1. When the connecting frame 33 slides relative to the slide box 34 and moves to the position where the first through hole 3311 is coaxially provided with the second through hole 341 and the threaded hole, the screw passes through the first through hole 3311 and the second through hole 341 at the same time and is threadedly connected to the threaded hole on the support plate 1. This not only limits and fixes the horizontal relative position between the connecting frame 33 and the slide box 34 and fixes the distance between the first abutment plate 31 and the second abutment plate 32, but also limits and fixes the overall position of the adjusting component 3 on the support plate 1, thereby facilitating the sequential placement of the battery cells into the accommodating space and avoiding the impact of the position change of the second abutment plate 32 on the placement of the battery cells.

[0039] Optionally, in this embodiment, the first slide 331 is provided with at least two first through holes 3311 along the stacking direction. This allows for further strengthening of the fixing effect of the distance between the first abutment 31 and the second abutment 32 by adding connecting members, further improving the clamping and positioning effect of the tooling on the battery cell module 100, ensuring that the battery cell remains in the same position during busbar installation, welding, and other processes, thereby guaranteeing product quality. Preferably, the first slide 331 is provided with three first through holes 3311 along the stacking direction.

[0040] Optionally, in this embodiment, along the horizontal direction perpendicular to the stacking direction (refer to...) Figure 1 As shown by the double-headed arrow on the Y-axis, at least two first through holes 3311 are symmetrically arranged on the first slide 331, and at least two second through holes 341 are correspondingly arranged on the slide box 34. With the above arrangement, after the connecting parts are set in the corresponding first through holes 3311 and second through holes 341, the first slide 331 can be kept in close contact with the two sides of the slide box 34 along the Y-axis, avoiding the situation of misalignment between the connecting frame 33 and the slide box 34. This can further ensure that the first abutment plate 31 and the second abutment plate 32 remain parallel, and further ensure the abutment effect on the battery cell module 100.

[0041] Optionally, in this embodiment, the slide box 34 is hollow, which can reduce the weight of the slide box 34 and improve the service life of the adjustment component 3. Preferably, the slide box 34 has two cavities 342 along the Y-axis, and a second through hole 341 is formed in the slide box 34 portion between the two cavities 342. Correspondingly, three first through holes 3311 are formed on the first slide 331 along the X-axis, which can further enhance the connection stability between the connecting frame 33 and the slide box 34 and ensure the accuracy of the installation position of the battery cell module 100.

[0042] Optionally, in this embodiment, reference is made to... Figure 1 As shown, the battery cell module assembly fixture also includes a tray 4, which includes a chassis 41, rollers 42, and anti-collision pads 43. A support plate 1 is connected to the chassis 41 to facilitate the transportation of the fixture and the battery cell module 100 on it by moving the chassis 41. The chassis 41 is square, and rollers 42 are provided at each of the four corners of the chassis 41. The rollers 42 play a guiding role, helping the chassis 41 to move along a predetermined track or path, ensuring the correct orientation of the battery cell module 100 during transportation and avoiding deviation. The anti-collision pads 43 are made of elastic material and are set at the edges of the chassis 41. The anti-collision pads 43 can effectively absorb the impact force from the outside and prevent the battery cell module 100 from being scattered due to vibration during transportation.
