Automatic reel changing device of membrane

Abstract

The invention relates to an automatic reel changing device of a membrane, which is used for winding working procedure of a battery core full-automatic winding machine. The automatic reel changing device comprises a tape alternation deviation correcting plate, two sets of unreeling mechanisms, a tape splicing mechanism, a tape cutting mechanism, a tension mechanism and a deviation correcting mechanism, wherein the tape alternation deviation correcting plate is vertically arranged on the front face of a base plate of the full-automatic winding machine; the two sets of unreeling mechanisms are arranged at one end of the tape alternation deviation correcting plate for providing the membrane released by the unreeling mechanisms for unreeling working procedure by turns; the tape splicing mechanism is arranged at the middle of the tape alternation deviation correcting plate for attaching the head part of a new material membrane of a standby material reel to the tail part of the current material membrane; the tape cutting mechanism is arranged between the two sets of unreeling mechanisms and an adhering mechanism for cutting excess material at the tail part of the current material membrane after adhesion and connection; the tension mechanism is connected with a tape splicing mechanism in sequence for controlling the tension forces of the membranes and providing membrane buffer for the winding working procedure; and the deviation correcting mechanism is arranged on the base plate for correcting deviation of the membrane for outputting the tape alternation deviation correcting plate. The tension mechanism, the tape splicing mechanism, the tape cutting mechanism and the deviation correcting mechanism are integrated integrally, so that the structure is greatly simplified, and various functions are realized in a limited space.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and relates to a cell sheet winding machine for batteries, in particular to a diaphragm changing device in the cell sheet winding machine. Background technique [0002] At present, the roll changing device of the diaphragm in the battery production equipment is generally a simple unwinding and splicing device, and there is generally no tension and buffer mechanism on the deviation correction plate. [0003] An automatic roll changing device in the prior art includes a first unwinding unit, a second unwinding unit and a glue application mechanism, and also includes a first cutting unit and a second cutting unit, and the glue application mechanism is used to make the first The first coil material of an unwinding unit is bonded to the second coil material of the second unwinding unit, and the first cutting unit is used for When connecting, cut off the first coil to unwind the second c...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the diaphragm changing device in the prior art are: the structure is complex, and the tension buffer mechanism needs to be set up separately; the existing diaphragm changing technology is not fully automatic, and human assistance is required, which reduces the efficiency of the machine and increases the Human contact with the diaphragm can cause contamination of the diaphragm material
