Automatic tape splicing machine for lithium battery pole piece

Abstract

The invention provides an automatic tape splicing machine for a lithium battery pole piece. The automatic tape splicing machine is full-automatic, fully enclosed and highly efficient, and can effectively ensure the clean standard of a working area. The machine includes a pole piece tape requiring threading or a pole piece tape in a transmission process; a pole piece tape transmission working area is equipped with a fracture tape detection device which can automatically detect fracture of the pole piece tape; the pole piece tape transmission working area is also equipped with multiple groups of spaced pole piece clamp devices opposite to each other up and down, which can automatically clamp and hold the fractured pole piece tape on an upper side and a lower side thereof at a same time; one side of the pole piece tape is provided with a fracture positioning device, which can be parallel to the pole piece and automatically move to the fracture of the pole piece tape according to a signal detected by the fracture tape detection device; and the fracture positioning device is mounted with a tape splicing device, which can move with the fracture positioning device and automatically draw the fracture pole piece tape and automatically adhere the tape.

Description

【Technical field】 [0001] The invention relates to the production and processing of lithium battery pole pieces, in particular to an automatic lithium battery pole piece splicing machine. 【Background technique】 [0002] When using fully automatic production equipment to make positive (negative) pole pieces of lithium batteries, the pole piece material roll is installed on the fixing device, and then the pole piece is introduced (threaded) and wound on the winding reel in order to carry out normal operation. Production; at the same time, there will be a pole piece phenomenon in the production process. At present, all are to finish threading and connecting belt manually. Tape threading is to manually introduce the end of the pole piece according to the strip threading path, and then introduce it to the winding reel and wind it on the rewinding reel. The broken tape is to butt the pole piece fragments in the process of processing, and then paste them with tape, which is easy to...

AI Technical Summary

Problems solved by technology

Tape threading is to manually introduce the end of the pole piece according to the strip threading path, and then introduce it to the winding reel and wind it on the rewinding reel. The broken tape is to butt the pole piece fragments in the process of processing, and then paste them with tape, which is easy to cause operation Personnel contact with pole pieces, bringing in static electricity, dust and other sundries, as well as dislocation of butt joints at fractures, uneven treatment of interfaces and other defects

For fully enclosed production equipment, it is difficult to ensure the normal operation of the equipment and the quality of the finished product by manual operation.
