[0019] The utility model has the following technical effects:

[0020] The wear-resistant strip of the utility model is used as a pallet consumable material and is in direct contact with the conveyor line during pallet transportation, so as to prevent the conveyor line from wearing the bottom plate during transportation. The positioning bushing plays a positioning function for the pallet, and cooperates with the positioning mechanism (not shown) at each station to accurately position the pallet to ensure the stability of automated production.

[0021] When adjusting the length of the battery cell, the utility model rotates the first knob plunger to make the lower end of the first knob plunger disengage from the positioning hole, pulls the adapter plate inward or outward, and the adapter plate moves inward or outward under the guidance of the guide rail and the slider, and the adapter plate drives the fixed component to move, and the fixed component drives the rotating component to move until the rotating component moves to the specified position, and then rotates the first knob plunger in the opposite direction to make the lower end of the first knob plunger embed into the positioning hole, so as to fix the adapter plate and complete the adjustment;

[0022] The utility model can be adapted to battery cells of different lengths, and when fixing battery cells of different lengths, there is no need to replace rotating components of different models, thus saving costs.

[0023] When the utility model is adjusted according to the thickness of the battery cell, the second knob plunger is rotated to disengage the second knob plunger from the circular hole, and the triangular rotating plate on the front side is rotated, and the triangular rotating plate drives the first limit block, the second limit block and the third limit block to rotate, and the rotation angle is sixty degrees or one hundred and twenty degrees. The triangular rotating plate on the rear side is rotated in the opposite direction, and the rotation angle is the same as that of the triangular rotating plate on the front side. The triangular rotating plate drives the first limit block, the second limit block and the third limit block to rotate. After the rotation is completed, the second knob plunger is rotated to make the inner end of the second knob plunger embedded in the corresponding circular hole to fix the triangular rotating plate, complete the adjustment, and then the battery cell is placed between the first limit block, the second limit block or the third limit block, and the battery cell is fixed under the support of the support bar at the bottom of the battery cell.

[0024] The triangular rotating plate of the utility model can be adapted to three different specifications and thicknesses of battery cells by rotating and switching positions. The front triangular rotating plate rotates sixty degrees each time and the rear triangular rotating plate rotates sixty degrees in the opposite direction each time to form one specification. When fixing battery cells of different thicknesses of the same length or battery cells of different lengths of the same thickness next time, only the corresponding thickness or length needs to be adjusted. The operation is simple, and there is no need to replace the triangular rotating plate, thereby saving costs.

[0025] When transporting battery cells of different lengths or three different thicknesses, the utility model only needs to adjust the length or thickness of the tray to the appropriate position, and the operation process is simple and can be adjusted quickly, saving changeover time. Moreover, because a set of trays is compatible with multiple products produced by the production line, there is no need to replace the tray from the production line, and there is no need to set up a tray placement area around the production line, thus saving space.
