Abstract

The invention discloses a charge coupled device (CCD) feedback correction closed-loop control method. The CCD coupled device (CCD) feedback correction closed-loop control method comprises the steps ofacquiring winding images of multiple groups of battery cells at a preset position, wherein the preset position comprises positions, at which the battery cell winding position can be shot, of a positive electrode, a separator and a negative electrode; determining a reference line of battery cell winding; respectively calculating a deviation value of the positive electrode and/or the negative electrode and/or the separator relative to the reference line according to the acquired winding images of current groups of battery cells at the preset position; adjusting a current setting value of a corresponding correction sensor according to the deviation value of the positive electrode and/or the negative electrode and/or the separator relative to the reference line; and controlling the corresponding correction sensor to drive a correction execution mechanism so as to correct the positive electrode and/or the negative electrode and/or the separator during the feeding process according to the adjusted setting value. The invention also discloses a CCD feedback correction closed-loop control device and control system. With the CCD feedback correction closed-loop control method provided by theinvention, the correction accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery automation equipment, in particular to a CCD feedback deviation correction closed-loop control method, a CCD feedback deviation correction closed-loop control device, and a CCD feedback deviation correction closed-loop control system including the CCD feedback deviation correction closed-loop control device. Background technique [0002] In the lithium battery production process, the cell winding process is a key technical link. The anode, separator, and cathode are sequentially sent to a winding needle to be wound to form a battery cell. In this process, the alignment of pole pieces (anode and cathode) is an important indicator to measure the quality of the battery cell. [0003] In the prior art, a deviation correction sensor is used to detect whether the pole piece is deviated, and when the pole piece is deviated, the position of the pole piece is corrected by controlling the deviation...
