[0028] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0029] The present utility model discloses a pre-pressing fixture for a battery cell module, which is a fixture for pre-pressing a battery cell module before shaping and packing. The overall structure of the pre-pressing fixture is set as Figure 1 shown, and mainly includes: a fixture bottom plate 1, a battery cell stacking component 3, a battery cell extrusion component 2, and a fixture fixing component 4;

[0030] Among them, the fixture bottom plate 1 is used as a structural support component. While satisfying the setting of the battery cell stacking component 3 and the battery cell extrusion component 2, it is installed on the desktop of the workbench 5 through the fixture fixing component 4.

[0031] The fixture fixing component 4 and the fixture bottom plate 1 cooperate with each other to fix the fixture body to the desktop of the workbench, avoiding the displacement of the fixture caused by pushing and pulling the quick clamp handle during the extrusion of the battery cells. As Figure 3 shown, the fixture fixing component 4 includes a connecting plate 41, a locking block 42, a screw 43, and a locking pad 44;

[0032] The connecting plate 41 is used to connect the fixture bottom plate 1, so that the fixture fixing component 4 is arranged below the periphery of the fixture bottom plate 1. The locking block 42 is fixed at the bottom end of the connecting plate 41, and the two together form an L-shaped structure, thus cooperating with the fixture bottom plate 1 to form a clamping cavity. The screw 43 is arranged in the threaded hole opened in the locking block 42 through a threaded structure, and the screw 43 passes upward through the locking block 42 and is connected to the locking pad 44. The locking pad is located in the clamping cavity. During use, the locking pad 44 is jacked upward by tightening the screw 43, so that the desktop of the workbench is clamped between the fixture bottom plate 1 and the locking pad 44, thereby fixing the pre-pressing fixture at the edge of the desktop of the workbench.

[0033] The battery cell stacking component 3 and the battery cell extrusion component 2 are supported and arranged on the fixture bottom plate 1. The battery cell stacking component 3 forms a receiving cavity for placing the battery cells 6, which can meet the simultaneous placement of multiple battery cells and play a role in positioning the battery cells; the battery cell extrusion component 2 pre-presses the battery cells through a quick clamp.

[0034] First, as Figure 1 shown, the battery cell pressing component 2 is supported and arranged on the fixture bottom plate 1 through a vertical plate structure. Then, as Figure 4As shown in the figure, the cell extrusion component 2 includes a quick clamp 21 and an extrusion plate 22. The quick clamp 21 is a finished product, and the extrusion plate 22 is fixed to the front end of the transmission rod of the quick clamp 21. When the quick clamp 21 is pushed and pulled, the extrusion plate 22 can move back and forth with the transmission rod, and the extrusion plate 22 acts on the cell 6 at the accommodation cavity of the cell stacking component 3. During use, just push the quick clamp handle forward, and the extrusion acting on the cell in the form of an extrusion plate can ensure that the extrusion surface is stressed dispersedly, avoiding local stress on the cell and causing damage. Moreover, an extrusion protection plate 23 is fixedly laid on the front end surface of the extrusion plate 22. The extrusion protection plate is made of PU material and has a certain elasticity, which can further strengthen the protection effect when extruding the cell.

[0035] As Figure 5 shown, the cell stacking component 3 includes a positioning plate 32 and a positioning support plate 31. The positioning plate is installed on the positioning support plate 31, and the positioning support plate 31 is fixedly connected to the tooling bottom plate 1 to realize the support setting of the cell stacking component 3. As Figure 1 shown, the heights of the supports of the cell extrusion component 2 and the cell stacking component 3 need to be such that the extrusion plate can act on the cell in the accommodation cavity.

[0036] For the convenience of describing the cell stacking component 3, the positioning plate 32 is divided into a bottom positioning plate 32a and a side positioning plate 32b. Among them, there are two groups of bottom positioning plates 32a in total. The two groups of bottom positioning plates 32a are symmetrically distributed and joined together to form a V shape. The side positioning plate 32b is fixed on the same side of the two groups of bottom positioning plates 32a; thus, an accommodation cavity is jointly enclosed by the bottom positioning plate 32a and the side positioning plate 32b. Moreover, positioning protection plates 34 are adaptively laid on the surfaces of the bottom positioning plate 32a and the side positioning plate 32b. During use, the cells are placed obliquely on the positioning protection plates in sequence, and the V-shaped structure distribution feature enables the cells to align the bottom and sides of the cells by their own weight.

[0037] In addition, this compacting prefabrication tooling is equipped with a cell splitting knife 7. As Figure 6 shown, the cell splitting knife 7 has a slope structure feature and adopts Teflon difference value, which can easily split the extruded and misaligned cells and avoid the influence of the knife body sticking with glue on the use.

[0038] To sum up, for the compacting prefabrication tooling of the cell module disclosed in the present utility model, the specific operation process is as follows: As Figure 2 shown, this compacting prefabrication tooling is integrally fixed at a suitable position on the workbench desktop through the tooling bottom plate and the tooling fixing components; adjust the clamping position and clamping force of the quick clamp to ensure that this tooling will not damage the cells while clamping the cells.

[0039] During use, tear off the back glue of the battery cell and place it obliquely on the battery cell stacking component. Press it tightly, then push the quick clamp to make the extrusion protection plate contact and press the battery cell, and hold for 3 seconds. Then release the quick clamp, and the battery cell is pre-compressed and completed. Subsequently, it can be placed on the packing table for subsequent processes.

[0040] Compared with the traditional method of directly placing and packing single battery cells during battery cell packing, it is easy to misplace the placement, and it is time-consuming and laborious for workers to carry them. Through pre-compressing and prefabricating multiple battery cells into a whole before packing the battery cells, and then performing conventional packing. Taking a module with 66 battery cells as an example, each time 3 battery cells are pre-compressed into one body for illustration. According to the traditional method, workers need to carry, place and paste 66 times to place all the battery cells in place, which consumes a great deal of physical strength of the workers, and the number of carrying times is too many, and it is also easy to be misaligned and make mistakes during placement, resulting in low packing efficiency and low output of the battery cell module. By using this pre-compression and prefabrication tooling, workers can pre-compress 3 battery cells in advance. During the subsequent module packing process, the number of times workers carry is reduced to 22 times, and the method that does not completely rely on manual labor also reduces the difficulty of placement and alignment, improving work efficiency.

[0041] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.
