Description

Technical Field

[0001] This utility model relates to the field of battery extrusion testing technology, specifically a battery module extrusion device. Background Technology

[0002] In the manufacturing process of battery modules, multiple individual battery cells are typically arranged in a row and pressed tightly together to reduce gaps between them. Then, the row of individual cells is bundled together using end plates and side plates to form the battery module. During assembly, extrusion fixtures are usually used to limit the sides of the battery module before pressing the two ends to complete the assembly.

[0003] For example, the utility model patent with authorization announcement number CN219959082U discloses a battery module extrusion device. This device can effectively control the magnitude of the extrusion force applied by the first pressure plate to the fourth side, thereby controlling the size of the battery module after extrusion and exhibiting good adaptability.

[0004] However, in actual use, the pressure applied by the extrusion component is entirely borne by the fixing component, while the fixing component on the right side is only fixed to the mounting plate at the bottom. The pressure applied to the upper part may cause uneven stress on the fixing component. When the pressure is too high, the uneven stress on the fixing component may pose certain safety hazards, thereby affecting the normal use of the device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figures 1-4 A battery module extrusion device includes: a base 1, on which a placement platform 11 for placing a battery module 19 is mounted at the upper end; an extrusion baffle 12 is mounted on the left side of the upper end of the base 1; an extrusion mounting plate 13 is mounted on the right side of the upper end of the base 1; a servo electric cylinder 14 is mounted on the extrusion mounting plate 13, the telescopic end of the servo electric cylinder 14 passing through the extrusion mounting plate 13; and the corner positions of the extrusion baffle 12 and the extrusion mounting plate 13 are fixedly connected by extrusion connecting rods 15; a guide assembly 2, mounted on the upper end of the base 1, for guiding an extrusion pusher 17; and an adjustment assembly 3, mounted on the base 1, for adjusting the position of the battery module 19.

[0018] The working principle of this utility model is as follows: In specific use, the battery module 19 is placed on the placement platform 11. Then, the position of the battery module 19 is adjusted by the adjustment component 3. Subsequently, the servo electric cylinder 14 extends and pushes the extrusion push plate 17 to move, so that the extrusion push plate 17 extrudes the battery. The extrusion connecting rod 15 set at the corner of the extrusion baffle 12 can hold the extrusion baffle 12, making it more stable and preventing the upper part of the extrusion baffle 12 from deforming to the left, thus ensuring the safety of the device and better meeting the usage requirements.

[0019] As a further embodiment, the guide assembly 2 includes a pair of guide slides 21 installed on the front and rear sides of the upper end of the base 1. Each guide slide 21 is equipped with a guide slide seat 22. The upper end of the guide slide seat 22 is fixed with a pressing connecting seat 16, and the pressing push plate 17 is installed on the pressing connecting seat 16.

[0020] By setting the guide slide 22 in conjunction with the guide slide rail 21, the stability of the extrusion connecting seat 16 movement can be improved, thereby improving the stability of the extrusion push plate 17 movement and facilitating the extrusion operation of the battery module 19.

[0021] As a further embodiment, the adjustment assembly 3 includes an adjustment mounting base 31 mounted on the upper end of the base 1. An adjustment threaded rod 32 is threadedly mounted on the adjustment mounting base 31. An adjustment push plate 33 is rotatably mounted on the end of the adjustment threaded rod 32. A pair of adjustment guide sleeves 34 are also mounted on the adjustment mounting base 31. An adjustment guide rod 35 is slidably inserted into each adjustment guide sleeve 34. The end of the adjustment guide rod 35 is fixedly connected to the adjustment push plate 33. In this embodiment, to facilitate rotation of the adjustment threaded rod 32, an adjustment handwheel is also fixed to the end of the adjustment threaded rod 32. An adjustment shim 36 is also mounted on the side of the adjustment push plate 33 near the battery module 19. By setting the adjustment guide sleeves 34 in conjunction with the adjustment guide rods 35, the stability of the movement of the adjustment push plate 33 can be improved.

[0022] The working principle of the adjustment component 3 is as follows: During adjustment, the adjustment handwheel is rotated, which drives the adjustment threaded rod 32 to rotate, thereby causing the adjustment threaded rod 32 to push the adjustment push plate 33 to move, thereby pushing the battery module 19 to move, realizing the adjustment of the position of the battery module 19, which facilitates the extrusion work.

[0023] As a further embodiment, a displacement sensor 18 for monitoring the extrusion deformation of the battery module 18 is also installed on the side of the extrusion mounting plate 13 near the extrusion push plate 17, and a flat plate pressure sensor 10 for monitoring the extrusion pressure is also installed on the side of the extrusion push plate 17 near the servo electric cylinder 14.
