Detection device and lithium battery production line

The utility model discloses a detection device and a lithium battery production line, the detection device is used for detecting a tab weld seam of a lithium battery, the detection device comprises a mounting rack, a visual detection mechanism and a smoothing mechanism, the mounting rack is provided with a detection space, and the lithium battery is fixed in the detection space; the visual detection mechanism is connected with the mounting frame and is used for detecting a tab weld of the lithium battery; and the flattening mechanism is connected with the mounting frame and used for flattening the tabs, and after flattening, the visual detection mechanism performs detection operation. According to the technical scheme of the utility model, the flattening mechanism is adopted for pre-flattening, so that the tabs can be kept horizontal during detection, the surfaces of the tabs are prevented from being shielded, the detection effect is ensured, and the detection precision is improved. 本实用新型公开一种检测装置和锂电池生产流水线，其中，
