Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a milling machine for battery module rework. Background Technology

[0002] With the rapid development of the new energy industry, the production of energy storage battery modules has surged. Battery modules are typically assembled from multiple individual cells by bonding mica sheets or heat insulation cotton, and then tightened with steel strips. Their terminals are connected in series and parallel by welding conductive busbars (aluminum busbars / copper busbars).

[0003] During the production process, defective battery modules may be produced. These defective modules need to be disassembled and repaired to recover usable components, such as individual battery cells and steel strips. Currently, when repairing battery modules, the weld seams between the conductive bars and terminals of the battery module must first be removed using a milling machine, and then the module is transferred to an independent workstation where the steel strips are removed by compression.

[0004] Existing battery module repair methods require multiple handling of the battery modules. Due to the weight of the battery modules, handling them increases the intensity of manual labor and the risk of dropping them, and is also time-consuming, resulting in low repair efficiency. In addition, milling machine work platforms typically use fixed positioning blocks to hold the battery modules in place, making the work platform unsuitable for battery modules of different sizes, thus reducing its versatility.

[0022] This invention provides a milling machine for reworking battery modules, comprising a frame, a work platform, a first fixing component, and a second fixing component. A milling cutter is mounted on the frame to remove the weld seams between the conductive bars and terminals of the battery module. The work platform is mounted on the frame and is used to hold the battery module.

Next, the second fixing component continues to move along the first direction closer to the battery module, pressing against it to remove the steel strip. The milling machine used for battery module reworking can remove the weld between the conductive busbar and the terminal post while simultaneously removing the steel strip, eliminating the need to handle the battery module, reducing manual labor intensity, minimizing the risk of the battery module falling, and improving reworking efficiency. Furthermore, the second fixing component's ability to move along the first direction allows the work platform to accommodate battery modules of different sizes, offering high versatility.

[0033] like Figure 1 and Figure 2As shown, this embodiment provides a milling machine for battery module rework, including a frame 1, a work platform 2, a first fixing component 3, and a second fixing component 4. A milling cutter is mounted on the frame 1 to remove the weld seams between the conductive bars and terminals of the battery module 100.

[0034] When reworking the battery module 100, firstly, the battery module 100 is placed on the work platform 2, with the side of the battery module 100 facing the first fixing component 3 abutting against the first fixing component 3. Then, the second fixing component 4 is adjusted so that it moves along the first direction closer to the side of the battery module 100 and abuts against the side of the battery module 100 facing away from the first fixing component 3, thereby firmly fixing the battery module 100 against both sides along the first direction, facilitating the milling cutter to remove the weld between the conductive busbar and the terminal post.
