The battery box plays a key role in reinforcing the battery position, reducing external impact and maintaining battery safety. The battery box is generally made of metal materials with good processing plasticity through any kind of die-casting, stamping, and extrusion.

The fixed plate is connected to the screw rod through the rotation of the nut seat, so that the user can adjust the handwheel to realize the position of the screw rod on the nut seat, and then realize the adjustment of the vertical position of the picking mechanism on the screw rod base, which is convenient for the picking mechanism to pick up battery boxes of different sizes, which is conducive to improving the universality of the unloading mechanism.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The user adjusts the preset position of the picking mechanism through the vertical moving mechanism in the vertical direction through the vertical adjustment mechanism in advance. Then, after the unloading mechanism is operated, the unloading mechanism moves downward to the preset position through the vertical moving mechanism, and picks up the battery box through the picking mechanism, so that the battery box is stably and safely located on the unloading mechanism, and then the battery box is transferred to the predetermined transfer position through the vertical moving mechanism and the horizontal moving mechanism. The unloading mechanism then releases the picking mechanism to safely place the battery box at the predetermined position. The cooperation of the vertical moving mechanism and the horizontal moving mechanism allows the battery box to be transferred within a larger space range, which is conducive to increasing the degree of freedom of the layout of the battery box production device, and the vertical adjustment mechanism allows the unloading mechanism to accurately pick up battery boxes of different sizes and positions, which is conducive to improving the universality of the unloading mechanism;

[0026] 2. When the cylinder is telescopic, the cylinder drives the cylinder connecting plate to telescope, and then the cylinder connecting plate drives the vertical adjustment mechanism to move in the vertical direction. The fixed plate is connected to the screw rod through the nut seat, so that the user can adjust the hand wheel to realize the position of the screw rod on the nut seat, and then adjust the vertical position of the picking mechanism on the screw rod base, which is convenient for the picking mechanism to pick up battery boxes of different sizes, which is conducive to improving the universality of the unloading mechanism;

[0027] 3. The first protrusion cooperates with the first groove to guide and supply energy to the moving position of the cylinder connecting plate, which is beneficial to the stability and accuracy of the moving position of the cylinder connecting plate; since the screw base and the screw itself have moving weight, it is difficult to bear the weight through the connection position between the screw and the threaded seat, and the direction position of the screw and the screw base is also difficult to stably confirm. The first groove can not only bear the weight of the screw base and the screw through the fixed plate and the threaded seat, but also has the guiding energy supply of the guide screw base, which is beneficial to improve the stability and accuracy of the vertical moving mechanism;

[0028] 4.
