Problems solved by technology

However, due to the above-mentioned use of the frontal light source to shoot the pole piece, the edge of the pole piece is more prone to imaging blur, so that the accuracy of the image information of the pole piece obtained is low, which in turn affects the deviation correction accuracy of the pole piece

Abstract

The invention provides a pole piece detection device. The pole piece detection device comprises a bottom plate, a light source and an image acquisition device. A groove is arranged in a surface of oneside of the bottom plate, a cover plate covers an opening of the groove, and the cover plate is used for supporting a pole piece; the light source is arranged in the groove and used for irradiating apositioning detection area; light emitted by the light source can penetrate through the cover plate; and the image acquisition device is arranged on one side, away from the light source, of the coverplate and used for acquiring image information of the pole piece located in the positioning detection area by receiving the light penetrating through the cover plate. The pole piece detection devicecan effectively avoid a problem of blurred imaging at an edge of the pole piece so that accuracy of the acquired image information of the pole piece can be effectively improved, and deviation rectification precision of the pole piece can be greatly increased.

Description

technical field [0001] The invention belongs to the technical field of battery processing, and in particular relates to a pole piece detection device. Background technique [0002] During battery processing, a stacking device is generally used to transport the pole pieces to the stacking table for stacking the pole pieces. Before the pole piece is transported to the stacking table, it is often necessary to collect the image of the pole piece to obtain the image information of the pole piece, and then the position of the pole piece can be corrected according to the image information. [0003] At present, generally, a light source and a camera are arranged on one side surface of the pole piece to illuminate the surface of the pole piece through the light source, and the surface of the pole piece is photographed by the camera to obtain an image of the pole piece. However, due to the use of the frontal light source to photograph the pole piece, the edge of the pole piece is pro...
