Full-function detection method, equipment, medium and system for pole piece production winding defect

Abstract

The invention provides a full-function detection method for the winding defect of the pole piece, which includes the steps of: detecting the position of the pole piece, measuring the size, detecting the glue sticking defect, detecting the blue glue, searching for the parameter coordinates, calculating the coordinate distance, correcting the pole piece deviation, and receiving the in-position signal , collect the image of the bare cell, and detect the appearance size of the bare cell. The invention relates to an electronic device and a readable storage medium, which are used for implementing a full-function detection method for the winding defect of a pole piece. The invention also relates to a full-function detection system for the winding defect of the pole piece sheet. The invention realizes the automatic detection of the position of the pole piece, the adhesive tape on the pole piece, the glue sticking outcrop, the sticking leaking metal, and the blue glue. Automatic detection of the appearance size of bare cells can meet the huge demand and high quality requirements of consumers for lithium batteries.

Description

technical field [0001] The invention relates to the technical field of detection of winding defects of pole piece production, in particular to a full-function detection method, equipment, medium and system for winding defects of pole piece production. Background technique [0002] At present, lithium batteries have been widely used in various industries, such as mobile phones, tablets, notebooks, desktop computers, electric cars, electric buses, etc. Consumers have a very large demand for lithium batteries, and the quality requirements of lithium batteries are getting higher and higher. In the existing pole piece processing process, the pole piece position, the tape on the pole piece, the sticking outcrop, the sticking leaking metal, and the blue glue are generally completed at one time by the precision of the processing equipment itself. The requirements of the battery are constantly improving, and the generation of defective products is inevitable. In the prior art, manua...

Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a full-function detection method for pole piece winding defects, which solves the problem of low efficiency and large errors in the prior art for manual detection of processed pole pieces , unable to meet the huge demand and high-quality requirements of consumers for lithium batteries. The existing deviation correction method can only correct the deviation by inserting the pole piece into the coil needle. The deviation correction accuracy is low, and the quality of the battery winding cannot be guaranteed. Existing measurement methods lead to low measurement accuracy of bare cells, which cannot meet the increasing high-precision requirements of cell design
