A continuous nickel plating device for battery case steel strip

Abstract

The invention relates to a continuous nickel plating device for steel strips of battery shells, comprising an electroplating tank capable of containing plating solution, the upper sides of the two ends of the electroplating tank are respectively used for the steel strip to pass in and out, and the upper side of the electroplating tank is provided with a connection with the negative pole of the power supply. Negative rods, located on both sides of the negative rods in the electroplating tank, are respectively provided with a positive rod connected to the positive pole of the power supply and immersed in the plating solution. Each positive rod is connected with a nickel anode, and the steel strip is penetrated into the plating solution from one end of the electroplating tank. Then pass through the plating solution from the lower side of a nickel anode, then penetrate the plating solution again after contacting the pole rod from the upper side of the negative pole, and finally pass through the other end of the electroplating tank from the lower side of another nickel anode. In the present invention, the steel strip passes through the lower side of the negative pole, and the negative pole is always immersed in the plating solution, thereby ensuring that the steel strip is always immersed in the plating solution; at the same time, the present invention contacts the bottom of the steel strip through the roller, and then through the roller device and the steel strip. The upper surface of the steel strip is in contact, thus ensuring that the steel strip communicates with the negative pole.

Description

Technical field [0001] The invention relates to the field of continuous nickel plating of steel strips for battery shells, in particular to a continuous nickel plating device for battery shell steel strips. Background technique [0002] In the production process of battery shells, some companies use barrel nickel plating, and some companies use continuous nickel plating. During continuous nickel plating, the steel strip used in the battery case should be nickel-plated. During the nickel plating process, the steel strip must be moved continuously, so how to ensure the connection between the steel strip and the negative electrode during the movement is very important. . Although the prior art discloses that a rolling negative electrode can be used to contact the steel strip, the contact between the steel strip and the negative electrode is still not well resolved, resulting in insufficient electroplating quality of the steel strip. At the same time, the existing continuous nickel...

Although the prior art discloses that the rolling negative electrode can be used to contact the steel strip, the contact between the steel strip and the negative electrode is still not well resolved, resulting in insufficient electroplating quality of the steel strip

At the same time, in the existing continuous nickel plating device, after the steel strip is immersed in the plating solution, because there is no device to ensure that the steel strip remains in the plating solution all the time, when the conveying speed of the steel strip is slightly faster, the steel strip is out of the plating solution, which affects the nickel plating. the quality of
