Description

Technical Field

[0001] This utility model relates to a power battery electrode connector tooling, which belongs to the field of power battery manufacturing technology. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the quality of power batteries, as a core component, directly affects the performance and safety of the entire vehicle. Simultaneously, improved production efficiency and reduced material loss enable companies to gain a competitive edge in the market. The production efficiency and product quality of the positive and negative electrode sheets of power batteries directly impact battery safety performance and market share. During the production of power battery positive electrode sheets, breakage is common. After breakage, blue tape is used to reattach the broken sheet on the splicing platform. The integrated roll forming and slitting machine has two splicing devices with pneumatic pressure rods, located in the unwinding and slitting mechanisms respectively, for electrode sheet splicing. However, conventional splicing devices have drawbacks: large size, high cost requiring the addition of cylinder devices. The winding mechanism is limited by space and cannot accommodate conventional splicing devices. Therefore, splicing after a breakage in the winding mechanism presents problems such as poor splicing leading to the introduction of foreign matter like tape into the battery cell, affecting subsequent production processes, reducing production efficiency, and increasing material loss. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a power battery electrode splicing tool that can improve splicing quality and production efficiency while reducing electrode splicing material loss.

[0004] This utility model discloses a power battery electrode connector tooling, characterized in that the tooling comprises:

[0005] Tooling body 1, wherein the tooling body 1 is a rectangular structure;

[0006] Electrode cutting groove 2, the electrode cutting groove 2 is located in the middle of the tooling body 1;

[0007] Mounting holes 3 are provided in four locations and are distributed at the four vertices of the tooling body 1.

[0008] Furthermore, the main body 1 of the tooling is made of acrylic material.

[0009] Furthermore, the dimensions of the tooling body 1 are 1500mm in length × 200mm in width × 10mm in height.

[0010] Furthermore, the dimensions of the electrode cutting groove 2 are 1400mm in length and 10mm in width.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model can guarantee the splicing effect. The original equipment has no winding mechanism and cannot install a conventional splicing platform device. The addition of the new splicing tooling ensures the alignment of the splicing and the effect of the blue adhesive.

[0013] 2. Using this new splicing fixture can reduce electrode material damage. The original splicing solution required all electrodes to be pulled off after slitting, and all electrodes from the slitting blade to the winding position were scrapped. By splicing at the winding shaft position, the number of scrapped electrodes from the splicing fixture to the winding position is greatly reduced.

[0014] 3. The tooling mechanism of this utility model is compatible with different types of power battery plates, and has strong versatility and flexibility. Attached Figure Description
