[0027] See Figure 1 This embodiment discloses an integrated mechanism for pre-pressing and full-pressing of a liquid injection device, including a conveying component 1, a nail feeding component 2, a nail suction and pressing component 3, and a lifting component 4. The nail feeding component 2, the nail suction and pressing component 3, and the lifting component 4 are all mounted on the conveying component 1.

[0028] The conveying assembly 1 includes support legs 11 and conveying structures 12. Two sets of conveying structures 12 are arranged side by side, and each set of conveying structures 12 has multiple support legs 11 connected to its bottom. It should be noted that the conveying structure 12 can be a roller conveying structure or a belt conveying structure, which are available on the market. In this embodiment, the conveying structure 12 is a roller conveying structure.

[0029] See Figure 2 The nail feeding assembly 2 includes a bracket 21, a mounting plate 22, a first cylinder 23, a guide structure 24, a nail feeding block 25, a nail supply fixing seat 26, and a nail supply pipe 27. The mounting plate 22 is fixed between two sets of conveying structures 12 by two sets of brackets 21. The first cylinder 23 is fixed on the mounting plate 22. The output end of the first cylinder 23 is connected to the nail feeding block 25 through the guide structure 24 and can drive the nail feeding block 25 to move along the horizontal conveying direction of the conveying assembly 1. The nail feeding block 25 is provided with a plurality of nail feeding holes 251. The nail supply fixing seat 26 is fixed on the mounting plate 22. The nail supply fixing seat 26 is provided with a nail supply pipe 27 corresponding to the number and position of the nail feeding holes 251. Glue nails are fed into the nail feeding holes 251 through the nail supply pipe 27.

[0030] Specifically, the guide structure 24 includes a connecting plate 241, a guide sleeve 242, and a guide post 243. The output end of the first cylinder 23 is connected to the connecting plate 241. The guide sleeve 242 is fixed on the mounting plate 22. Both ends of the connecting plate 241 are connected to the nail feeding block 25 through the guide post 243. The end of the guide post 243 away from the connecting plate 241 passes through the guide sleeve 242 and is connected to the nail feeding block 25.

[0031] See Figure 3 and Figure 4 The nail suction and pressing assembly 3 includes a support frame 31, a second cylinder 32, a fixed plate 33, a third cylinder 34, a nail suction and pressing air block 35, a switching pipe 36, and a pressing rod 37. The second cylinder 32 is fixed to the conveying assembly 1 by the support frame 31. The output end of the second cylinder 32 is connected to the fixed plate 33 and can drive the fixed plate 33 to move perpendicular to the horizontal conveying direction of the conveying assembly 1. The fixed plate 33 is provided with a third cylinder 34 and a nail suction and pressing air block 35 corresponding to the number and position of the nail feeding holes 251. The output end of the third cylinder 34 is connected to the pressing rod 37. The end of the pressing rod 37 away from the third cylinder 34 extends into the inner cavity of the nail suction and pressing air block 35. The switching pipe 36 is connected to the inner cavity of the nail suction and pressing air block 35.

[0032] Specifically, the switching pipe 36 is a vacuum-nitrogen switching pipe. When the pipe is switched to vacuum, the nail-adsorbing and pressing gas block 35 can adsorb the glue nails. When the pipe is switched to nitrogen, the nail-adsorbing and pressing gas block 35 can pre-press the adsorbed glue nails.

[0033] The lifting assembly 4 is disposed between the two sets of conveying structures 12. The lifting assembly 4 includes a lifting fixing seat 41, a lifting cylinder 42 and a lifting block 43. The lifting fixing seat 41 is fixed between the two sets of conveying structures 41. The lifting cylinder 42 is fixed on the lifting fixing seat 41. The output end of the lifting cylinder 42 is set upward and connected to the lifting block 43. The battery module 5 is placed on the lifting block 43.

[0034] The working principle of this embodiment is as follows: When performing nailing operations, the first cylinder 23 is activated, and the guide structure 24 drives the nail feeding hole 251 on the nail feeding block 25 to correspond one-to-one with the nail supply pipe 27. The glue nail falls onto the nail feeding hole 251 on the nail feeding block 25. At this time, the battery module 5 moves on the conveying structure 12 to the top of the lifting block 43. The telescopic end of the lifting block 43 retracts and the second cylinder 32 is activated, which drives the nail suction and nail pressing air block 35 to correspond one-to-one with the nail feeding hole 251 to achieve sealing. The switching pipe 36 is switched to a vacuum state, and the nail suction and nail pressing air block 35 can suck up the glue nail. Next, the first cylinder 23 extends, driving the lifting cylinder 42 to lift the battery module 5 through the lifting block 43, so that the battery injection hole corresponds one-to-one with the suction nail pressing block 35. At this time, the switching pipe 36 is switched to nitrogen gas. The positive pressure generated by the nitrogen gas inside the switching pipe 36 is used to pre-press the glue nail onto the injection hole. Then, the third cylinder 34 is started to drive the pressing rod 37 to press down, so that the glue nail in the switching pipe 36 is pressed at the injection hole at the set height. At this time, the pressing is completed. The third cylinder 34 and the second cylinder 32 retract, and the battery module 5 moves to the next station with the material conveying component 1.

[0035] In summary, this embodiment integrates pre-stressed nails and fully-stressed nails into the same mechanism, simplifying the structure, reducing the floor space, and improving production efficiency.
