[0002] Battery box spring clip press-fitting mechanisms are typically used to precisely and reliably install metal spring clips into battery boxes, ensuring stable conductive contact and efficient assembly.

[0003] A search of Chinese patent CN223000021U reveals a spring plate installation fixture, comprising: a base, a support fixture, a fixture body, a pressure handle, a transmission mechanism, a pressure column, and a pressing fixture. The base and fixture body are positioned opposite each other. The support fixture is mounted on the base, and a bottom valve body, a check valve, and a star-shaped spring plate are placed on the support fixture. The bottom valve body and check valve are placed on the support fixture, and the star-shaped spring plate is placed on the check valve, with the central area of ​​the star-shaped spring plate in contact with the check valve. The pressure column is mounted on the fixture body, and the pressing fixture is mounted on the end of the pressure column corresponding to the support fixture. The pressure handle and transmission mechanism are mounted on the fixture body. The pressure handle is connected to the pressure column through the transmission mechanism, driving the pressure column and the pressing fixture to press down and lift. When the pressing fixture presses down, it contacts the outer periphery of the star-shaped spring plate, causing its outer periphery to bend downwards. This patent solves the technical problems of low efficiency and unstable quality in manual installation of star-shaped spring plates.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. In the process of pressing the spring sheet of the battery box, the spring sheet needs to be installed in the pressing equipment and then the pressing equipment is used for pressing. Manual labor often cannot keep up with the speed of the pressing equipment, the feeding speed is slow, the pressing efficiency is low, and it is not convenient to position the battery box during the pressing process. It is easy to deviate during the pressing process. Utility Model Content

A feeding mechanism and a positioning mechanism are provided on the mounting frame 1. The feeding mechanism includes a drive assembly mounted on the mounting frame 1. A movable frame 7 is provided on the drive assembly. A support assembly is provided between the mounting frame 1 and the movable frame 7. Multiple sets of snap-fit ​​assemblies are provided on the movable frame 7. The battery box body 17 that is in contact with two contact blocks 16 is clamped between two clamping plates 15. Two spring sheet bodies 18 are placed inside the two mounting slots 8.

[0027] In this embodiment of the utility model, the operator controls the conveying equipment to transport the battery box body 17 to the unloading station, and controls the extension end of the first hydraulic cylinder 2 to extend, so that the extension end of the first hydraulic cylinder 2 can drive the pressure plate 3 to move downward, so that the pressure plate 3 can press the two spring sheet bodies 18 in the movable frame 7 into the inner side of the battery box body 17.

[0028] Figures 1 to 4 As shown, the drive assembly includes a drive motor 4 fixedly mounted on the mounting frame 1, a reciprocating lead screw 5 fixedly mounted on the output end of the drive motor 4, a threaded block 6 fixed to the movable frame 7 threadedly mounted on the reciprocating lead screw 5, and multiple mounting slots 8 opened on the movable frame 7.

Two return springs 12 are connected to the inner wall of the fixed shell 11, and the ends of the two return springs 12 are connected to a snap-fit ​​block 13 slidably connected to the fixed shell 11.

[0029] In this embodiment of the invention, the operator places multiple spring sheet bodies 18 inside the mounting groove 8 in advance, so that the locking block 13 supports the spring sheet bodies 18 under the elastic support of the return spring 12. When the battery box body 17 moves to the unloading station, the spring sheet bodies 18 located at the unloading station are installed inside the battery box body 17 by pressing. During the pressing, the spring sheet bodies 18 squeeze the locking block 13, causing the locking block 13 to move into the inside of the fixing shell 11. When the spring sheet bodies 18 separate from the locking block 13, the return spring... Spring 12 can drive the locking block 13 to reset and move by its own elastic force, and control the drive motor 4 to run.

[0031] In this embodiment of the utility model, the operator controls the extension end of the second hydraulic cylinder 14 to extend a portion. When the battery box body 17 is transported to the unloading station, the battery box body 17 contacts the contact block 16. Then, the operator controls the extension end of the second hydraulic cylinder 14 to continue extending, so that the extension end of the second hydraulic cylinder 14 drives the clamping plate 15 to position and clamp the battery box body 17, thereby facilitating the pressing of the spring sheet body 18 onto the inner side of the battery box body 17 and preventing pressing misalignment.

[0032] Working principle: The operator controls the extension end of the second hydraulic cylinder 14 to extend part of its length. When the battery box body 17 is transported to the unloading station, the battery box body 17 contacts the contact block 16. Then, the operator controls the extension end of the second hydraulic cylinder 14 to continue to extend, so that the extension end of the second hydraulic cylinder 14 drives the clamping plate 15 to position and clamp the battery box body 17. The operator controls the extension end of the first hydraulic cylinder 2 to extend, so that the extension end of the first hydraulic cylinder 2 can drive the pressure plate 3 to move downward, so that the pressure plate 3 can press the two spring sheet bodies 18 in the movable frame 7 into the inner side of the battery box body 17.

[0033] By placing the spring sheet body 18 inside the mounting slot 8 of the movable frame 7, when the battery box body 17 moves to the unloading station, the spring sheet body 18 located at the unloading station is installed inside the battery box body 17 by press fitting. The drive motor 4 is controlled to run, so that the movable frame 7 drives other spring sheet bodies 18 to move to the unloading station, and spring sheet bodies 18 are added inside the mounting slot 8 after unloading.
