Abstract

The invention discloses an automatic unwinding, tape connecting and deviation rectifying device which comprises a rack, the rack comprises a base, an unwinding frame and a discharging frame, the base and the discharging frame are relatively fixed, and a deviation rectifying assembly is arranged between the base and the unwinding frame; and the deviation rectifying assembly comprises a vertical plate fixedly connected to the unwinding frame, a sliding block used for installing the unwinding frame and a first deviation rectifying device installed on the base, the sliding block is arranged on the base in a sliding mode, and the movable end of the first deviation rectifying device is fixedly connected with the vertical plate. When the automatic unwinding, tape connecting and deviation rectifying device works, a pole piece on the winding barrel is conveyed to the discharging frame from the unwinding frame to be unwound, in the process, the first deviation rectifying device monitors the position of the unwinding frame in real time, and if the unwinding frame deviates relative to the discharging frame, the first deviation rectifying device pushes the unwinding frame to integrally move on the base to conduct deviation correction, the unwinding precision and stability of the pole piece are effectively improved, and the quality of a battery is ensured.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to an automatic unwinding and splicing tape deviation correction device. Background technique [0002] With the strong support of the country's new energy battery industry, lithium batteries have been widely used due to their light weight, long cycle life, green and pollution-free, which has brought unprecedented development to the lithium-ion battery manufacturing industry. In order to improve the production efficiency of batteries, there are various mechanisms for manufacturing battery pole pieces, and their improvements and enhancements are also changing with each passing day. [0003] At present, the Chinese invention patent with the notification number CN20799834U discloses an automatic roll changing device for a lithium battery coating machine, which includes a first frame and a second frame. The first frame is provided with a rotating bracket assembly, and the r...
