The first clamping and flipping mechanism flips the battery cell from the first conveying mechanism by 180 degrees, and the appearance of the other large surface and the other side surface of the battery cell is detected by the second large surface detection mechanism and the second side surface detection mechanism. The second clamping and flipping mechanism places the battery cell from the second conveying mechanism on the third conveying mechanism or the NG storage and buffering mechanism. By realizing the one-time detection of the four surfaces of the battery cell, the present invention not only avoids the problem of missed detection, but also improves the detection efficiency.

Description

Technical Field

[0002] In the automated production process of existing power batteries, some of the battery cells may have appearance defects during the production and processing, such as scratches, dirt, pits, and breakages. When the appearance of the battery cell has defects, it may also affect the use safety of the product. Therefore, it is necessary to detect the appearance of the product on the production line of the battery cell and store the products with appearance defects separately.

Therefore, when detecting the appearance of such battery cells, it is necessary to detect four sides of the battery cell. Since there are many sides to be detected for one battery cell, if the traditional manual detection method is used, it may miss detecting a certain side due to human negligence, which will increase the omission rate of appearance defects and easily lead to the flow of products with appearance defects into the market.

[0073] In a specific implementation, when the battery cells on the incoming and outgoing conveyor belt reach the loading mechanism, the loading mechanism clamps and places the battery cells at the loading position of the first conveying mechanism, and then conveys the battery cells to the detection stations of the first large surface detection mechanism / the first side surface detection mechanism through the first conveying mechanism for appearance detection (wherein, the station sequence of the first large surface detection mechanism / the first side surface detection mechanism is not limited); then the battery cells are flipped by 180 degrees through the first clamping and flipping mechanism, and then placed at the loading position of the second conveying mechanism, and then conveyed to the detection stations of the second large surface detection mechanism / the second side surface detection mechanism through the second conveying mechanism for appearance detection (wherein, the station sequence of the second large surface detection mechanism / the second side surface detection mechanism is not limited); the detection mechanism uses a camera to scan / acquire images of the battery cells, and performs specific algorithm program recognition and analysis on the acquired battery cell appearance information (images / scanning information), and finally obtains the appearance detection results of the battery cells (including qualified and unqualified); after the second clamping and flipping mechanism flips and resets the qualified battery cells from the second conveying mechanism and places them on the third conveying mechanism, they are placed on the incoming and outgoing conveyor belt through the unloading mechanism for the next process, or the unqualified battery cells from the second conveying mechanism are placed on the NG storage buffer mechanism for storage.

[0076] The first jaw part or the second jaw part includes a fixing plate, an L-shaped moving plate, a positioning cylinder and jaws; the top end of the fixing plate is connected to the third cross plate, and both sides of the bottom end are slidably connected to one end of the L-shaped moving plate; the outer side of the other end of the L-shaped moving plate is connected to the jaws, and the inner side of the other end of the L-shaped moving plate is connected with a positioning cylinder; a positioning piece is arranged at the output end of the positioning cylinder; the positioning piece corresponds to the position where the jaws grip the battery cell.
