[0002] At present, the spacer pasting of battery packs mainly adopts two methods: manual and manipulator. The first is manual pasting. As the name implies, it is to manually tear off the release paper and then paste it on the large surface of the battery cell. The advantage is low cost and suitability for trial sample production. The disadvantage is poor spacer pasting accuracy, slow efficiency, and inapplicability to mass production. The second is the manipulator, which automatically grabs and pastes through equipment. The advantages are high efficiency and high pasting accuracy, which are suitable for mass production projects. The disadvantage is too high cost and inapplicability to sample parts and small-batch production. Content of the Utility Model

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] As Figure 1 shown, this embodiment provides a spacer sheet pasting device, including a fixed frame 1, a peeling rod 2, and a spacer sheet pasting mechanism 3.

[0030] As Figure 1As shown, a first release paper 5 is pasted on the top wall of the spacer 4, and a second release paper 6 is pasted on the bottom wall of the spacer 4. The upper left corner of the first release paper 5 protrudes and is provided with a punching hole, and the lower right corner of the second release paper 6 protrudes and is provided with a punching hole. Multiple groups of spacers 4 with the first release paper 5 and the second release paper 6 are arranged along the Z-axis in the fixed frame 1. A first fixing rod 11 is fixed near the protruding part of the first release paper 5 on the left side of the fixed frame 1, and the protruding punching holes of the first release paper 5 are all sleeved on the first fixing rod 11. A second fixing rod 12 is fixed near the protruding part of the second release paper 6 on the right side of the fixed frame 1, and the protruding punching holes of the second release paper 6 are all sleeved on the second fixing rod 12. A peeling rod 2 is fixed near the second fixing rod 12. The peeling rod 2 is arranged in a crutch shape, and the bent rod of the peeling rod 2 faces the top end of the second fixing rod 12.

[0031] As Figure 1 , Figure 3 , Figure 3 , Figure 4 shown, the spacer pasting mechanism 3 includes a connecting frame 31, an adjusting rod 32, a mounting seat 33, a pneumatic adjusting component 34, a fixing seat 35, and a suction cup 36. The connecting frame 31 is arranged in a lying L shape. The bottom of the cross bar of the connecting frame 31 is hinged with the adjusting rod 32. The free end of the cross bar of the connecting frame 31 is fixed with the mounting seat 33. The pneumatic adjusting component 34 is integrated in the mounting seat 33. The input end of the pneumatic adjusting component 34 is fixed with the adjusting rod 32. The adjusting rod 32 can make the pneumatic adjusting component 34 form a negative pressure. The output end of the pneumatic adjusting component 34 is communicated with the suction cup 36. The vertical rod of the connecting frame 31 and the bottom of the mounting seat 33 are fixed on the fixing seat 35. Multiple suction cups 36 are fixed on the bottom wall of the fixing seat 35. A barb 351 is fixed on the fixing seat 35 near the first fixing rod 11. The pneumatic adjusting component 34 includes a swing arm 341, a vacuum chamber 342, a piston 343, and an air pipe 344. The swing arm 341 is arranged in a mirror L shape. The vertical rod of the swing arm 341 is fixed on the adjusting rod 32. Holding the adjusting rod 32 upward can drive the swing arm 341 to move downward. The cross bar of the swing arm 341 is fixed on the piston rod of the piston 343. The piston body of the piston 343 is slidably connected in the vacuum chamber 342. The swing arm 341 can drive the piston 343 to move downward to form a negative pressure in the vacuum chamber 342. The free end of the vacuum chamber 342 is communicated with multiple suction cups 36 through multiple air pipes 344.

[0032] During use, the spacer 4 is arranged and placed inside the fixed frame 1. Pay attention to the placement direction so that the protruding punching holes of the first release paper 5 are all sleeved on the first fixed rod 11, and the protruding punching holes of the second release paper 6 are all sleeved on the second fixed rod 12. Then, hold down the adjusting rod 32, and the swing arm 341 drives the piston 343 to move downward to form a negative pressure in the vacuum chamber 342, thereby causing the suction cup 36 to generate a negative pressure. Then, use the suction cup 36 to suck the spacer 4 inside the fixed frame 1, and after sucking, translate it diagonally upward to the right. At this time, due to the limitation of the bent rod of the peeling rod 2 on the second release paper 6, the second release paper 6 will gradually separate from the spacer, which is convenient for personnel to clean. After the actions of sucking the spacer 4 and tearing the second release paper 6 at the bottom are completed, the pasting of the spacer 4 will be carried out. The specific steps are as follows: First, the fixed seat 35 is stuck on the large surface of the battery cell. Since the designed shape of the fixed seat 35 is modeled after the large surface of the battery cell, accurate positioning of the pasting position can be achieved when the fixed seat 35 is stuck on the large surface of the battery cell. After the positioning is completed, release the adjusting rod 32. After the suction cup 36 loses the air source, it automatically releases the spacer 4. Since the bottom surface of the spacer 4 contains an adhesive after tearing the second release paper 6, it will firmly adhere to the large surface of the battery cell, realizing the large surface pasting of the spacer 4. Finally, the barb 351 of the fixed seat 35 tears off the first release paper 5 on the back of the spacer 4. Finally, a complete set of actions for accurately pasting the spacer 4 and tearing off the first release paper 5 and the second release paper 6 is realized.
