Pole piece cleaning system and method

Abstract

The invention discloses a pole piece cleaning system and a pole piece cleaning method. The system comprises a transmission mechanism, a cleaning mechanism and a cleaning mechanism, wherein the transmission mechanism is used for conveying pole pieces on a preset conveying path; the adsorption platform is arranged on one side of the conveying path; the laser is arranged on the other side of the conveying path corresponding to the adsorption platform; the length direction position detection sensor is arranged on the adsorption platform and is used for detecting the actual position of the notch in the A surface of the pole piece relative to the adsorption platform in the length direction when the notch exists in the A surface of the pole piece; and the controller is in communication connection with the laser and the length direction position detection sensor, and is used for adjusting the deflection of the light emitting path of the laser in the length direction according to the actual position of the A surface notch in the length direction relative to the adsorption platform, so that the laser can clean the B surface of the pole piece according to the deflection of the adjusted light emitting path. According to the system, when the B face of the pole piece is cleaned, the notch of the A face serves as the reference, high-precision cleaning machining is achieved through light path deflection compensation, and the cleaning positioning precision of the notch is effectively improved.

Description

technical field [0001] The invention relates to the technical field of battery pole piece cleaning, in particular to a pole piece cleaning system and method. Background technique [0002] Electrode paste cleaning, one of the key specifications is the alignment of the front and back notches after cleaning. For gap coating, the traditional method is to detect the starting edge of gap coating, and after identifying the signal of the starting edge of gap coating, control the main drive module to move to a fixed length, pull the material belt to the cleaning position, and realize the pole piece positioning and cleaning . There are following defects in this method: [0003] 1) There is a misalignment error of the front and back sides of the incoming material for gap coating; [0004] 2) Affected by factors such as tension and main drive slippage, there is a certain error in the fixed length of the main drive pulling material away; [0005] 3) There is a certain error in the st...
