Problems solved by technology

[0002] With the development of lithium battery industry technology, the visual system CCD is gradually applied in actual production to measure the real-time changes in the width of the pole piece, to correct deviations in time, and to improve production efficiency and efficiency. MSA refers to measurement system analysis, which is the use of mathematics Statistical and graphic methods analyze the resolution and error of the measurement system to evaluate whether the resolution and error of the measurement system are suitable for the parameters to be measured, so the MSA operation is useful for checking the accuracy of measurement data of CCD and other measurement systems It is very important. For the CCD system, when doing MSA, it is necessary to repeatedly measure the width of the pole piece to obtain multiple sets of measurement data, and then obtain the analysis results according to the measurement requirements of MSA. However, due to the large fluctuations in the width of the pole piece in actual production , leading to the fact that the CCD system used to test the pole piece width cannot be accurately and effectively implemented in MSA analysis, and the repeatability and reproducibility are poor. In addition, in the case of using the pole piece to travel, the pole piece is easy to discount, break the belt, and cause a large loss

Abstract

The invention belongs to the technical field of a lithium ion battery, and particularly to a standard member for pole plate width testing. The standard member comprises a polyester high-molecular filmand a plurality of segments of square coatings which are plated on the belt moving surface of the polyester high-molecular film. The widths D of the segments of the coating are same. Furthermore thewidths D are 50-2000 mm. The length L of each segment of the coating is 50-1100 mm. Furthermore the lengths L of the segments of the coating gradually increase or gradually reduce. The difference between the lengths of two adjacent segments of coating is 0.1-2mm. The standard member for testing the CCD system pole plate is prepared through utilizing the polyester high-molecular film and the coating with relatively high adhesion force. The standard member has advantages of excellent physical property, no easy folding or breakage, effective reduction of a measurement result error of the CCD system, and higher data reliability in performing MSA by the CCD system. Furthermore the invention discloses a preparation method of the standard member for pole plate width testing, and an application method thereof.
