[0016] In this implementation, the first hopper mechanism 2 is used to store and provide explosion-proof sheets. The tray 22 is slidably connected to the top of the hopper mounting frame 21 to support the first carrier box 23. The first carrier groove on the top of the first carrier box 23 is used to place the explosion-proof sheets.

After replenishing the explosion-proof sheets, it is pushed to the predetermined position. At this time, the first positioning cylinder 25 drives the first positioning rod to rise and insert into the positioning hole to lock it, preventing it from shaking when the loading and transfer device 3 transfers the explosion-proof sheets. The first stop block 26 and the first limit block 27 cooperate to limit the movement of the tray 22. During operation, the loading and transfer device 3 first transfers the explosion-proof sheets to the intermediate transfer mechanism 1, which then transfers them to the loading position. Then, the loading and transfer device 3 transfers the explosion-proof sheets to the corresponding slots on the battery top cover.

[0017] Preferably, in this embodiment, both the first stop block 26 and the first limiting block 27 are L-shaped, with the vertical L-shaped end of the first stop block 26 facing upwards and the vertical L-shaped end of the first limiting block 27 facing downwards; a first sliding groove is formed at each of the top two ends of the material tray 22 along the length of the material tray 22, and a second sliding groove is formed on each of the top two sides of the material tray 22 along the width of the material tray 22; the first hopper mechanism 2 also includes two end limiting seats 28 and two side limiting seats 29; the end limiting seats 28 are L-shaped, and the bottom of the L-shaped horizontal end of the end limiting seat 28 is also...

The first carrier box 23 can be fixed by the end limiting seat 28 and the side limiting seat 29 to ensure its stability when transferring the explosion-proof sheet. At the same time, the end limiting seat 28 and the side limiting seat 29 can slide relative to the material tray plate 22, so that the position of the first carrier box 23 can be adjusted according to the actual use environment. Then, screws can be locked into the oval hole to lock it in place.

The first linear module 11 can drive the transfer platform 12 to move so as to move it horizontally to the predetermined loading position, waiting for the loading and transfer device 3 to transfer and load the material.

[0019] In one embodiment, the loading and transfer device 3 includes a transfer fixing frame 31 arranged on one side of the transfer mechanism 1, and a dual-moving linear module 32 mounted on the transfer fixing frame 31. The dual-moving linear module 32 is arranged along the length direction of the transfer mechanism 1, and the two moving parts of the dual-moving linear module 32 are respectively connected to a loading and transfer mechanism. The two moving parts of the dual-moving linear module 32 are respectively connected to a loading and transfer mechanism, and the two loading and transfer mechanisms can move independently. One loading and transfer mechanism is used to transfer the explosion-proof sheet in the first carrier box 23 to the first limiting groove of the transfer platform 12. Subsequently, the transfer platform 12 moves to the predetermined loading position, and the other loading and transfer mechanism transfers the explosion-proof sheet in the first limiting groove to the corresponding groove of the battery top cover.

The axially hollow structure of the motor shaft and the second air source connector 383 at the top of the motor shaft are used to connect to an external air source, allowing the suction cup at the bottom of the motor shaft to pick up the explosion-proof sheet. The R-axis rotary motor 381 can drive the motor shaft to rotate the explosion-proof sheet, thereby adjusting the angle of the explosion-proof sheet to adapt to different welding requirements. Furthermore, preferably, a rotating disk 384 is mounted on the upper part of the motor shaft of the R-axis rotary motor 381, and an R-axis sensing plate 385 is connected to the top of the rotating disk 384; a sensing fixing plate 386 is also connected to one side of the Z-axis lifting vertical plate 36, and a U-shaped photoelectric sensor 387 that works in conjunction with the R-axis sensing plate 385 is mounted on the bottom of the sensing fixing plate 386.
