Description

Technical Field

[0001] The present invention relates to a detection and repair device, in particular to a detection and repair device for power battery foil processing and a working method thereof. Background Art

[0002] Battery foil is a new type of high-end product used as a current collector for lithium-ion batteries. During use, battery foil has very high quality requirements, requiring the surface of the aluminum foil to have a uniform color, a flat surface, no color difference, no bright lines, and other defects. Therefore, during the processing of battery foil, monitoring and repair equipment is often required to detect defects in the battery foil itself and repair it, so as to facilitate the subsequent storage and use of the battery foil.

[0003] Chinese patent application number CN202110494532.5 discloses a device and method for detecting burrs on the side edges of battery aluminum foil. This device belongs to the technical field of battery aluminum foil detection devices and includes an equipment box and an aluminum foil sheet passing through the box. Feed chutes for the aluminum foil sheet are provided at both ends of the box. Two symmetrically mounted searchlight detection devices are installed inside the box. The searchlight detection devices include a searchlight mounted on the top of the aluminum foil sheet, encased in a lampshade with an open bottom. A projection screen is provided on the bottom of the inner wall of the box, positioned on one side of the aluminum foil sheet. The device illuminates the side edge of the aluminum foil sheet and projects the image onto the projection screen, magnifying the side edge. The projection recorded by the searchlight is viewed on a display screen for easy observation. When a burred aluminum foil sheet passes through the box, multiple light sensors detect a change in light intensity. A smearing device then marks the foil sheet, reducing eye fatigue and preventing omissions. The detection device disclosed in this patent can only detect burrs on the side edges of battery aluminum foil, resulting in a narrow detection range and low detection efficiency.
