Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to an end nickel plating device. Background Technology

[0002] The current collector of a lithium battery is primarily made of copper, requiring localized nickel plating, such as at the ends. Nickel plating requires an electric current. Current technology involves first spraying adhesive onto the areas where nickel plating is not desired, then applying the current for nickel plating, and finally removing the adhesive. However, this adhesive-based nickel plating method has several drawbacks. The adhesive removal process itself is time-consuming and labor-intensive, and there is a risk of incomplete removal of the adhesive. Summary of the Invention

[0003] In order to solve the technical problems of time-consuming, labor-intensive and adhesive residue caused by the nickel plating process of the current collector in the prior art, this application proposes an end nickel plating device, which solves the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides an end-plate nickel plating device for a current collector, comprising: a fixture, wherein the fixture is formed by a receiving base plate and a side plate to form a pressure cavity, the receiving base plate having a receiving channel for receiving the current collector, the receiving channel including a sealing section near the pressure cavity and a mating section away from the pressure cavity, the sealing section having a sealing element disposed therein, the mating section having a clearance fit with the nickel plating section of the current collector to be nickel plating, the current collector being disposed from the pressure cavity into the receiving channel, and the bottom strip of the current collector after being placed into the receiving channel abutting against the receiving base plate near the pressure cavity. On one side of the pressure cavity, the nickel-plated section of the manifold after being inserted into the receiving channel protrudes from the side of the receiving base plate away from the pressure cavity. The portion between the bottom strip of the manifold after being inserted into the receiving channel and the nickel-plated section squeezes the sealing element within the sealing section and is enveloped by the sealing element. The pressure block includes a pressing section and a circumferentially expanding positioning section. The pressing section enters the pressure cavity and presses against the bottom strip of the manifold to position the manifold. The positioning section abuts against the end face of the side plate of the fixture away from the receiving base plate to position the pressure block.

[0006] Furthermore, the receiving base plate has multiple receiving channels for receiving the current collector, and the multiple receiving channels are distributed in a straight line.

[0007] Furthermore, the pressure block is elongated (two pressure blocks are arranged in each fixture), one of the pressure blocks is pressed against one end of the bottom strip of all the collectors in the fixture, and the other pressure block is pressed against the other end of the bottom strip of all the collectors in the fixture.

[0008] Furthermore, the fixture is made of conductive material, and the pressure block is made of plastic steel material.

[0009] Furthermore, the seal is made of a deformable, soft material.

[0010] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0011] The present invention relates to an end-plate nickel plating device. A current collector is placed into a fixture, and the fixture and a sealing element disposed within it are used to shield the portion of the current collector that does not require nickel plating. Specifically, the nickel-plated section of the current collector protrudes outside the fixture, while the portion outside the nickel-plated section is shielded by the fixture. The connection between the nickel-plated and non-nickel-plated sections is sealed with the sealing element, serving as a separation. Then, the entire device is powered on for nickel plating. This fixture-based shielding and separation replaces the existing method of spraying adhesive onto the current collector, thus solving the technical problems of time-consuming, labor-intensive processes and adhesive residue caused by the existing adhesive-spraying nickel plating process.
