Embodiment Construction
[0032] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with the schematic diagram, but it is not limited thereto.
[0033] If there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, they are only used to explain the relative positions of the components in a specific posture (as shown in the figure) Relationships, movement conditions, etc., if the specific posture changes, the directional indication also changes accordingly.
[0034] In addition, in the present invention, descriptions involving "first", "second", etc. are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or impl...

The invention relates to a pole piece edge detection device, and a pole piece edge detection method. The pole piece edge detection device comprises a base, an imaging assembly arranged on the base, alight source assembly and a stabilizer used for being tightly attached to a pole piece. The pole piece edge detection device is arranged on a pole piece production line, the light source assembly focuses light beams on the outer edge of the stabilizer, when a pole piece passes through the stabilizer, the pole piece is tightly attached to the stabilizer, the edge of the pole piece penetrates through a set area, an imaging assembly shoots a pole piece image of the set area to serve as sampling detection, and the pole piece can be detected in the production process. According to the invention, real-time detection is carried out on a production line; the light source assembly is combined to improve image brightness; the stabilizer ensures that the edge of the pole piece is stable in a set areaso as to ensure that the pole piece edge image of the set area shot by the imaging assembly meets the detection requirement, the problem that the imaging assembly cannot shoot a qualified detection image during real-time detection of the lithium battery pole piece is solved, and the technical effects of instant detection and accuracy on a production line are achieved.
Description
Technical field [0001] The invention relates to the field of lithium battery pole pieces, in particular to a pole piece edge detection device and a detection method. Background technique [0002] The lithium battery pole piece adopts a roll-to-roll production method, and the normal production process does not allow the strip to be broken, and the pole piece is very thin. If real-time detection is used, the image detected by the imaging component will have insufficient brightness and smear, etc. Circumstances, so that the imaging component cannot capture a qualified inspection image. Therefore, the sampling of the pole pieces of the lithium battery can only be done after the production is completed, and the sampling result will also have a certain lag. At present, the detection of the edge of the lithium battery pole piece adopts a manual sampling method, which has low sampling efficiency and low accuracy. Summary of the invention [0003] The technical problem to be solved by th...
