Embodiment Construction
[0041] 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 schematic diagrams, but is not limited thereto.
[0042] 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 certain posture (as shown in the drawings) relationship, motion, etc., if the particular pose changes, the directional indication changes accordingly.
[0043] In addition, in the present invention, the descriptions involving "first", "second" and so on are only for the purpose of description, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implici...

The invention relates to a pole piece edge detection device and detection method, and the pole piece edge detection device comprises a base, an imaging assembly arranged on the base, a light 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 the 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, the imaging assembly shoots a pole piece image of the set area for sampling detection, and the pole piece can be detected in the production process. Instant detection on a production line is adopted, the light source assembly is combined to improve the image brightness, and the stabilizer ensures that the edge of the pole piece is stable in the set area, so that the pole piece edge image of the set area shot by the imaging assembly meets the detection requirement; and the problem that the imaging assembly cannot shoot qualified detection images when the lithium battery pole piece is detected in real time is solved, and the technical effects of real-time 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] Lithium battery pole piece adopts the roll-to-roll production method, the normal production process is not allowed to break the tape, 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. The situation, so that the imaging component cannot capture a qualified inspection image. Therefore, the sampling of lithium battery pole pieces can only be carried out after the production is completed, and the sampling results will also have a certain hysteresis. At present, the detection of the edge of the lithium battery pole piece is manually checked, which has low sampling efficiency and low accuracy. Contents of the invention [0003] The technical problem to be solved by the embodime...
