Abstract

The invention discloses a coating length measuring device which is used for measuring the coating or/and interval length of the pole piece and the alignment length of the front side and the back side. The coating length measuring device comprises a bracket, a discharge glue roller and a first drum, wherein the discharge glue roller and the first drum are respectively rotatably connected with the bracket and are parallel to each other; two line linear optical fiber sensors are oppositely arranged between the discharge glue roller and the first drum; the linear optical fiber sensors are respectively and electrically connected with a processor; and the processor determines the coating or/and interval length and the alignment length of the front side and the back side according to the signal time difference between the input opening interruption and the closing interruption of the linear optical fiber sensors as well as the length electric signal of the rotary encoder. By utilizing the linear optical fibers, the invention can prevent the measurement data error when the pole piece coating trailings occur. Meanwhile, the coating or/interval length and the alignment length of the front side and the back side can be directly obtained because of adopting a rotary transducer, thereby reducing the error and enhancing the precision of the coating or/interval length and the alignment length of the front side and the back side.

Description

technical field [0001] The invention relates to the technical field of pole piece coating, in particular to a coating length measuring device for coating both the front and back sides of a pole piece. Background technique [0002] In the field of lithium-ion batteries, the requirements for coating accuracy are getting higher and higher. Parameters such as coating length, blank length, and front and back alignment are important parameters of lithium-ion batteries, which affect the subsequent process of the battery and the performance of the battery. High precision requirements (within ±0.5mm). In order to control the quality of the above parameters, the usual method is: arrange a special person to detect the above parameters at the tail of the coating machine, regularly sample inspection, measure the coating length and interval length with a length ruler, and use a pin to break the pole piece to detect the front and back sides Align the parameters, and modify the coating pro...
