Abstract

A square lithium battery large surface appearance defect detection system comprises a large surface detection mechanism which comprises an X-direction driving device, a linear sliding device and a camera scanning assembly and is used for detecting the large surface of a square lithium battery; a battery cell turnover mechanism which is arranged between the large surface detection mechanism and a jacking transplanting mechanism, comprises a low-speed rotating cylinder, a rotating shaft and a mounted bearing, and is used for driving a battery positioning and rotating mechanism to turn over; the battery positioning and rotating mechanism which is arranged on the battery cell turnover mechanism, comprises a bottom rotating device and a top clamping device, and is used for clamping the square lithium battery; and the jacking and transplanting mechanism which is mounted on the equipment mounting surface, and comprises a jacking driving device, a jacking buffering device and a suction tool and is used for lifting the position of the square lithium battery to meet the battery cell height state of the subsequent process, wherein thejacking and transplanting mechanism and the large-surface detection mechanism are arranged at the two sides of the battery cell turnover mechanism respectively. The invention further comprises an application method. According to the square lithium battery large surface appearance defect detection system and application method thereof, the appearance detection accuracy is improved, and the problems of manual misjudgment and low working efficiency are overcome.

Description

technical field [0001] The invention relates to a large surface appearance defect detection system of a square lithium battery and an application method thereof, belonging to the technical field of lithium battery detection. Background technique [0002] At present, the country vigorously promotes new energy vehicles, and the lithium battery industry has also made great progress. In this case, the requirements for the appearance inspection of finished lithium batteries will become more and more stringent. According to the shape, lithium batteries are mainly divided into soft packs, cylinders, and squares, and the square lithium batteries are aluminum shells. During the production process, the aluminum shell is easy to be bruised and scratched, and after leaving the warehouse and before the coating process, high-precision detection of the appearance defects of the square lithium battery is required. Relying on manual inspection under traditional operations, there are risks s...
