Double-tab rectification implementing method

Abstract

The invention discloses a double-tab rectification implementing method. The double-tab rectification implementing method comprises the following steps: confirming automatic rectification, wherein a material is automatically rectified between two sensors for the first time, and recording relative width of the material as the reference width of the material; if the tabs enter the detection ranges ofthe sensors, judging whether the width of the material is greater than the reference width of the material or not, if the width of the material is greater than the reference width of the material, stopping rectification, otherwise, carrying out rectification continuously till the material is between the two sensors; inquiring whether the actual width of the material becomes small, if so, markingthe current value as the reference width, and updating the reference width of the material; inquiring whether the actual width of the material becomes great, if so, increasing the new reference widthbased on the original reference width, and updating the reference width of the material. Through cycled judgment for many times, the double tab rectification implementing method carries out automaticrectification, is high in degree of intelligence and high in precision, and overcomes the defect that in the prior art, the precision of a product is affected as malfunctions are easily generated by the tabs through the sensors during double tab rectification automatic operation.

Description

technical field [0001] The invention relates to the technical field of automatic deviation correction of bipolar ear materials for power lithium batteries, and in particular to a method for realizing deviation correction of bipolar ears. Background technique [0002] At present, the known automatic correction of bipolar ear materials for power lithium batteries adopts the method of setting the center ratio of the left and right sensor positions, requiring the left and right sensors to be installed on the same horizontal line, the error is less than 0.2mm, and the width of the ear is mostly 5-20mm. It is easy to sag, and the lugs on both sides cannot sag at the same rate, which requires high die-cutting precision of the two pole pieces. During automatic deviation correction, when the tab passes the sensor, it is easy to cause a malfunction, which affects the product accuracy. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the te...
