Double-sided multi-section coating automatic alignment method

Abstract

The invention discloses a double-sided multi-section coating automatic alignment method. The double-sided surfaces are set to be a surface A and a surface B, the method comprises the following steps that S1, a first section coating length L1 and an intermittent length L2 of the surface A are set along the belt moving direction at interval; S2, the distances D1 started from a first coating startingpoint to a second coating starting point is calculated, wherein L 1 + L 2 is equal to D1; S3, the surface A color mark input interruption permission is started; S4, whether the surface A color mark input interruption exists or not is judged, the encoder position is recorded when the surface A color mark input is interrupted, otherwise the surface A color mark input interruption is continuously waited; S5, whether the surface A color mark input interruption is the first input or not is judged; S6, whether D is greater than or equal to 0.95*D1 and less than or equal to 1.05*D1 is true or not isjudged; and S7, the surface B coating is stopped when a coating stopping signal is received. According to the double-sided multi-section coating automatic alignment method, the phenomenon that when the surface A is wrongly coated, the surface B continues being coated in a misaligned mode, so that the whole roll pole piece is scrapped is avoided.

Description

technical field [0001] The present application relates to a lithium battery coating machine, in particular to an automatic alignment method for double-sided multi-stage coating. Background technique [0002] During the coating process, the lithium battery coater needs to align the coating position of side A with the coating position of side B. At present, when the coating position of side A changes abnormally (such as missing coating or overcoating), the coating position of side B cannot be automatically identified and aligned, which may easily cause the coating position of side A to be different from that of side B. Misalignment occurs, affecting coating quality. Contents of the invention [0003] The purpose of the present invention is to provide an automatic alignment method for double-sided multi-stage coating, which solves the phenomenon that when a coating error occurs on side A, side B continues to carry out dislocation coating, resulting in the scrapping of the en...
