When the electric push rod 13 works to make the upper shell 6 close to the lower shell 7, the air in the box body 2 12 will enter the two boxes 18 through the pipe 15 and the two pipes 2 16, so that the two pistons 19 can move toward the middle, thereby moving the two push rods 10 toward the middle, so that the two blocks 11 can fix the lower shell 7, so that the device has the function of automatically fixing the lower shell 7;

[0042] The use process of the utility model is as follows: when the upper shell 6 and the lower shell 7 of the battery shell need to be assembled together, the upper shell 6 is placed inside the U-shaped frame 5 and the upper shell 6 is contacted with the fixing block 1 17 and the baffle 20. Then, the three electric push rods 2 18 are controlled to work so that the fixing block 2 19 can contact with the upper shell 6, thereby achieving the clamping and fixing work of the upper shell 6. Then, the lower shell 7 is placed on the assembly table 1 and the lower shell 7 is contacted with the front side of the box body 2 12. When placing, the lower shell 7 is located directly below the upper shell 6.

[0043] Then, the four electric push rods 13 are controlled to work to move the movable plate 4, the U-shaped frame 5 and the upper shell 6 downward, so that the upper shell 6 will be close to the lower shell 7. When the movable plate 4 moves downward, the telescopic rod 14 and the piston 2 13 can also move downward. When the piston 2 13 moves downward, the air in the box 2 12 can enter the two box 1s 8 under the action of the pipe 15 and the two pipes 2 16, so that the pistons 19 in the two box 1s 8 will move synchronously to the middle, and then the two push rods 10 will move synchronously to the middle, so that the block 11 will contact and clamp the two sides of the lower shell 7. When the block 11 clamps the lower shell 7, the upper shell 6 and the lower shell 7 are not in contact. At this time, the electric push rod 13 is continued to be controlled to move the movable plate 4 downward. When the downward thrust is greater than the elastic force of the spring 25, The fixing pin 23 will move downward with the moving plate 4, the U-shaped frame 5 and the upper shell 6, while the piston 2 13 and the cylinder 24 will not continue to move downward. At this time, the upper shell 6 moves downward and can be buckled and assembled on the lower shell 7. After the buckling and assembly is completed, the electric push rod 2 18 is controlled to work so that the fixing block 2 19 is not in contact with the upper shell 6. Then the electric push rod 1 3 is controlled to move the moving plate 4, the U-shaped frame 5 and other components upward and reset. At the same time, the spring 25 rebounds to make the telescopic rod 14 longer. When the bottom end protrusion of the fixing pin 23 contacts the inner wall of the top of the cylinder 24, the piston 2 13 can be pulled to move upward, and then the air in the two boxes 8 is sucked back, so that the two pistons 9, the push rod 10 and the block 11 can be reset. Then the assembled ones can be removed, and then the assembly work can be continued according to the same principle.

[0044] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the above technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
