Description
Technical Field
[0001] This invention specifically relates to a lithium battery PACK module extrusion mechanism, belonging to the technical field of module extrusion mechanisms. Background Technology
[0002] The lithium-ion battery pack module extrusion mechanism is a core piece of equipment in the lithium-ion battery pack production line. It is used to precisely compress, shape, and bundle multiple battery cells, end plates, heat insulation components, etc., to form modules with stable structure, accurate dimensions, and consistent electrical performance. Its core functions are to eliminate gaps, control dimensions, ensure welding / assembly accuracy, and improve thermal management and safety.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] Please see Figures 1-8 As shown, a lithium battery PACK module extrusion mechanism includes:
[0042] The extrusion operating frame 1 adopts a double-layer operating structure, with electronic extruders 2 arranged around its perimeter. Adjustable slides 3 are installed at both ends of the extrusion operating frame 1 to adjust the working position of the electronic extruders 2. Fixed mounting slots are provided at both ends of the extrusion operating frame 1, and the adjustable slides 3 are slidably installed in the fixed mounting slots. Positioning mounting plates 301 are integrally provided on both sides of the adjustable slides 301. Positioning threaded holes are provided on both sides of the positioning mounting plates 301, extending to the extrusion operating frame 1. Fixing bolts 302 are installed in the internal threads of the positioning threaded holes. A stabilizing support frame 201 is fixedly mounted on the outer side of the electronic extruders 2. Stabilizing threaded holes are provided on three sides of the extrusion operating frame 1. The stabilizing threaded holes pass through both sides of the output end of the adjustable slides 3 and the stabilizing support frame 201, and connecting bolts 202 are installed in the internal threads of the stabilizing threaded holes.
[0043] The core function of the aforementioned lithium-ion battery pack module extrusion mechanism is to achieve precise extrusion of the lithium-ion battery pack module. Its double-layer extrusion operating frame 1 provides stable support for the overall operation, while the surrounding electronic extruders 2 can perform multi-directional extrusion and shaping of the module. The adjusting slide 3 can flexibly adjust the lateral working position of the electronic extruder 2 to adapt to the extrusion requirements of modules of different sizes. The cooperation between the fixed mounting slot, the positioning mounting plate 301, and the fixing bolts 302 can lock and fix the adjusting slide 3 to prevent displacement during operation. The stable support frame 201 on the outside of the electronic extruder 2, together with the stable threaded holes and connecting bolts 202 that penetrate the adjusting slide 3 and the stable support frame 201, further strengthens the installation stability of the electronic extruder 2, ensuring uniform force and no deviation during the extrusion process. Ultimately, this achieves the effect of improving the extrusion accuracy of the module, ensuring the stability of the module structure, and adapting to the extrusion operation of modules of different specifications.
[0044] A stabilizing lifting component 4 is installed on one side of the extrusion operating frame 1 and is used to adjust the working height of the electronic extruder 2. The stabilizing lifting component 4 includes: a stabilizing mounting groove 401, which is welded and fixed to the upper side of the extrusion operating frame 1; a bidirectional threaded rod 402, which is rotatably installed in the stabilizing mounting groove 401; a control motor 403, which is fixed to one end of the stabilizing mounting groove 401 and whose output end is fixedly connected to the bidirectional threaded rod 402; a mirror adjustment block 404, which is slidably installed inside both ends of the stabilizing mounting groove 401 and is threadedly connected to both ends of the bidirectional threaded rod 402; a rotating connecting rod 405, whose upper end is rotatably connected to the lower end of the mirror adjustment block 404; and a stabilizing mounting plate 406, which is rotatably connected to the rotating connecting rod 405 on both sides and has the electronic extruder 2 fixedly installed inside.
[0045] The stabilizing lifting component 4, as an important part of the lithium battery PACK module extrusion mechanism, is installed on one side of the extrusion operating frame 1. Its core function is to precisely adjust the working height of the electronic extruder 2 to adapt to the extrusion requirements of different PACK modules, ensuring the accuracy and adaptability of the extrusion operation. In its specific structure, the stabilizing mounting groove 401 is fixed to the upper side of the extrusion operating frame 1 by welding, providing a stable mounting base for the entire lifting assembly. The bidirectional threaded rod 402 is rotatably installed inside the stabilizing mounting groove 401, and the control motor 403 is fixed to one end of the stabilizing mounting groove 401, with its output end fixedly connected to the bidirectional threaded rod 402, which can drive the bidirectional threaded rod 402 to rotate smoothly. The mirror adjustment block 404 is symmetrically slidably installed on the stabilizing lifting component 402. The two ends of the fixed mounting groove 401 are threadedly connected to the two ends of the bidirectional threaded rod 402. When the bidirectional threaded rod 402 rotates, it can drive the two mirror adjustment blocks 404 to slide synchronously in opposite directions. The upper end of the rotating connecting rod 405 is rotatably connected to the lower end of the mirror adjustment block 404, and the lower end is rotatably connected to both sides of the stable mounting plate 406. The electronic extruder 2 is fixedly installed inside the stable mounting plate 406. When the mirror adjustment block 404 slides, it will drive the stable mounting plate 406 to rise and fall smoothly through the rotating connecting rod 405, thereby realizing the synchronous adjustment of the working height of the electronic extruder 2. The entire structure has smooth transmission and precise adjustment, which can effectively ensure the stability of the electronic extruder 2 during the lifting process and avoid the impact of height adjustment deviation on the extrusion quality of the module.

There is no need for manual pushing of the module, which greatly reduces the intensity of manual labor and further improves the work efficiency. The whole process realizes automated, high-precision, and highly compatible module extrusion assembly operations, which greatly improves production efficiency and module assembly quality.
