Abstract

The invention discloses a cutting method for electrode coating. The cutting method comprises the following steps: firstly feeding a pole piece to the blanking procedure smoothly by a piece storage system, blanking and cutting the electrode coating with a laser knife according to the given size and then feeding the blanks to the forming procedure smoothly by the piece storage system to undergo forming cutting. The cutting method is characterized in that the two procedures are completed through laser cutting; the gripping and conveying procedure of the electrode coating is automatically completed by a machine; and dust collection devices are arranged in the forming procedure. By adopting the method, not only is the labor cost reduced and the stability of the pole piece cutting process ensured, but also the work efficiency is improved.

Description

technical field

[0001] The invention relates to a method for manufacturing a lithium battery, in particular to a cutting method for electrode coating. Background technique

[0002] In the production process of the product lithium battery, the forming and cutting process of the electrode sheet is a very important process in the whole production process, which directly affects the production efficiency, quality and quantity of the product. In the general production process, people’s blanking and forming process for electrode sheet coating is to manually send the electrode coating to the bottom of the pressing mechanism, and use the die to punch to obtain the electrode sheet of the desired shape. However, such a process may produce burrs, which may puncture the diaphragm between the positive and negative electrodes and cause a short circuit between the positive and negative electrodes of the battery. In severe cases, the battery may explode. Moreover, the life of the mechanica...
