[0007] The present invention provides a defective battery cell sorting device through improvement, which has the following improvements and advantages compared with the prior art:

[0008] The first one is a defective battery cell sorting device described in the present invention. The sorting column foot is started to drive the two support shafts to move. When the two support shafts rotate from the top to the bottom, the distance between the two support shafts will become shorter, so that one end of the parallel connecting shaft is fixedly connected to the other end and movably connected. When the two support shafts are close to each other, the two L-shaped support plates are kept parallel by the parallel connecting shaft limiter. The parallel connecting shaft slides on the inner side of an L-shaped support plate, so that the angle and distance of the two L-shaped support plates remain unchanged when the two support shafts are at the top, so that the battery cell to be inspected is placed on the top of the storage roller, and the balance is maintained by fixing the two parallel connecting shafts. This process can facilitate the storage and fixation of the battery cell and eliminate the process of placing a positioning frame. When the inspection is completed, the two support shafts move to the top of the mounting base plate, and the corresponding sorting electric cylinder is started according to the inspection result.

Because the parallel connecting shaft at the other end is fixed by the fixed pressure strip, the L-shaped support plate rotates, so that the L-shaped support plate pulls the supporting bottom block upward, pulls the adjustment rotating plate to rotate upward, and the adjustment outer cylinder moves along the adjustment inner axis so that the two adjustment outer cylinders are close to each other, squeezing the compression spring, so that the battery cell to be tested slides to one side through the storage roller, and similarly, another sorting electric cylinder is started to recover the battery cell to be tested and slide to the other side. After completion, the sorting electric cylinder is extended and retracted, and the adjustment rotating plate is pushed downward by the compression spring until it is reset. After the parallel connecting shaft enters the top of the fixed bottom block, the fixed rotating shaft is reset by the torsion spring to fix the parallel connecting shaft, and the sorting is completed;

[0009] Second, the defective battery cell sorting device described in the present invention has a parallel connecting shaft during sorting. When the parallel connecting shaft on one side is rotated, the lower pressing shaft will rotate, so that the lower pressing shaft presses down the unfolding pressure column, pulls the protective top block downward, and makes the protective slider squeeze the protective spring downward, so that the top of the protective top block is lower than the storage roller, which is convenient for the battery cell to be tested to slide down. The lower pressing shaft is arranged between the L-shaped support plate and the fixed bottom block, so that the two lower pressing shafts can move through the adjustment slot as the parallel connecting shaft and the inside of the L-shaped support plate move, which is convenient for sorting.

During the operation of the device, the various components cooperate closely and the movements are smooth, ensuring the stable progress of the sorting work. At the same time, the device also has the advantages of simple structure, small space occupation, easy operation and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Because the parallel connecting shaft 14 at the other end is fixed by the fixed pressure strip 22, the L-shaped support plate 38 rotates, so that the L-shaped support plate 38 pulls the support bottom block 37 to move upward, pulls the adjustment rotating plate 33 to rotate upward, and adjusts the outer cylinder 27 along the adjustment The inner shaft 29 moves to bring the two adjustment outer cylinders 27 closer to each other, squeezing the compression spring 31, so that the battery cell 13 to be tested slides to one side through the storage roller 39. Similarly, another sorting electric cylinder 46 is started to recover the battery cell 13 to be tested and slide to the other side. After completion, the sorting electric cylinder 46 is extended and retracted, and the adjustment rotating plate 33 is pushed by the compression spring 31 to rotate downward until it is reset. After the parallel connection shaft 14 enters the top of the fixed bottom block 18, the fixed rotating shaft 20 is reversed and reset by the torsion spring 21, so that the parallel connection shaft 14 is fixed and the sorting is completed.
