[0002] As the core component of the battery, the battery cell usually includes components such as the anode, cathode, electrolyte and separator. The battery cell realizes the charging and discharging of the battery based on the transmission of ions in the electrolyte and the flow of electrons between the cathode and cathode. Among them, battery cell winding is a key process in the battery manufacturing process. It refers to the process of winding materials such as positive electrode sheets, negative electrode sheets and separators to form a battery cell. The battery cell formed by winding has a higher energy density and better performance.

[0003] During the cell winding process, a certain amount of testing is required to ensure product quality. The testing content mainly includes visual inspection of the cell size or appearance. At present, visual inspection mainly uses a visual correction device, which includes an automatic zoom liquid lens. The automatic zoom liquid lens adjusts the focal length by external control to change the shape or refractive index of the liquid. When the cell is wound, the position moves. The automatic zoom liquid lens can ensure clear imaging requirements during visual inspection.

[0004] However, the structure of the automatic zoom liquid lens is relatively complex, which makes the manufacturing cost of the automatic zoom liquid lens relatively high. At this time, the production cost of the battery cell is relatively high, and the daily maintenance of the automatic zoom liquid lens is inconvenient. Utility Model Content

[0009] In some implementations, the limit assembly includes a limit plate, and limit sensors are provided at both ends of the limit plate arranged along the sliding direction of the slide seat.

[0010] In some implementations, a first adjustment component is disposed between the slide and the detection component, and the first adjustment component drives the detection component to adjust its position along the Y-axis direction.
