The swing arm 320 has a first end 321 and a second end 322 opposite to each other, and the main shaft 310 passes through the joint of the first end 321 and the second end 322 in the swing arm 320 . In one embodiment, the first end 321 and the second end 322 are arranged at an included angle. As shown in FIG. 4 , the first end 321 and the second end 322 are substantially at right angles, so the swing arm 320 has an L-shaped structure as a whole.

The gluing roller 330 is rotatably disposed on the first end 321 of the swing arm 320 . The roll surface of the glue sticking roller 330 can be provided with air holes, and by generating negative pressure or a certain degree of vacuum in the glue sticking roller 330, the smooth side (that is, the side without adhesiveness) of the glue paper 500 can be adsorbed on the glue sticking roller 330. The roller surface of rubber roller 330. After the adhesive tape 500 is absorbed by the adhesive roller 330, the swing arm 320 is rotated to make the adhesive roller 330 reach the position of the battery cell 400, and then the adhesive roller 330 is rotated so that the adhesive side of the adhesive paper 500 can be pasted on the battery cell 400 to complete the action of pasting glue.

The push plate mechanism 340 is disposed on the second end 322 of the swing arm 320 for pushing the swing arm 320 in a predetermined direction. In the viewing angle shown in FIG. 4 , the push plate mechanism 340 exerts a thrust roughly toward the right, so that the adhesive roller 330 on the swing arm 320 can approach the position of the battery cell 400 so that the adhesive paper absorbed by the adhesive roller 330 500 can be pasted on the surface of battery cell 400 .

The plate pulling mechanism 350 is disposed on the second end 322 of the swing arm 320 for pulling the swing arm 320 in a direction opposite to the predetermined direction. In the viewing angle shown in FIG. 4 , the pulling mechanism 350 exerts a pulling force generally toward the left. When the pushing mechanism 340 pushes the swing arm 320 to a preset position, the pulling mechanism 350 pulls the swing arm 320 in the opposite direction, so that The swing arm 320 is fixed at the preset position. The above preset position is the gluing position. In this gluing position, by rotating the gluing roller 330 , the adhesive paper 500 can be pasted on the battery cell 400 . It can be understood that the swing arm 320 also has an adsorption position, at which the adhesive paper 500 picked up by the glue taking unit 100 can be absorbed onto the glue application roller 330 . In other words, the change of the output distance of the pushing plate mechanism 340 and the pulling plate mechanism 350 is used to jointly determine the swing angle of the swing arm 320, so that the gluing roller 330 is switched between the suction position and the gluing position, thereby The gluing roller 330 can absorb the adhesive paper 500 and paste the absorbed adhesive paper 500 on the surface of the battery cell 400 .

In the present invention, the preset position of the swing arm 320 is jointly determined by the push plate mechanism 340 and the pull plate mechanism 350, as long as the output distance of the push plate mechanism 340 and the pull plate mechanism 350 is adjusted, the preset position can be changed, thereby It meets the needs of different gluing positions, and avoids the disadvantages of inaccurate gluing or unsuccessful gluing caused by changes in gluing positions caused by different types of batteries 400 in the prior art.

Further, a bearing 360 is provided on the second end 322 of the swing arm 320 , and both the pushing mechanism 340 and the pulling mechanism 350 abut against the bearing 360 to push or pull the swing arm 320 . Since the bearing 360 is rotatable, the friction between the pushing mechanism 340 and the pulling mechanism 350 can be reduced during the interaction with the second end 322 , which facilitates the position change or fixation of the swing arm 320 .

In one embodiment, both the pushing plate mechanism 340 and the plate pulling mechanism 350 are arranged on a plate body 370 . The board body 370 can be provided independently, and can also form an indirect connection with the above-mentioned substrate 110 .

The push plate mechanism 340 includes a push plate 341 that is driveably disposed on the plate body 370 , and a push block 342 that is driveably disposed on the push plate 341 , and the push block 342 is used to communicate with the second end 322 of the swing arm 320 side contact. The transmission of the push plate 341 and the push block 342 can be achieved by the cylinder, for example, the push plate 341 is set on the plate body 370 by a cylinder, and the push block 342 is set on the push plate 341 by another air cylinder. By separately setting the push plate 341 and the push block 342, the push plate 341 can initially position the swing arm 320, and then the push block 342 can accurately position the swing arm 320, so that the swing arm 320 can be rotated to the desired position more precisely, that is, it can This enables the adhesive roller 330 to reach the preset position more accurately.

The plate pulling mechanism 350 includes a pulling block 351 , wherein the pulling block 351 and the pushing block 342 are respectively used to abut against opposite sides of the second end 322 of the swing arm 320 to position the swing arm 320 . In order to stagger the setting of the pulling block 351 and the pushing block 342 so as not to interfere with each other, the pulling block 351 and the pushing block 342 can be respectively arranged at two axial ends of the bearing 360 . The plate pulling mechanism 350 also includes a cylinder 352 for driving the pull block 351 and a guide rod 353 for guiding the pull block 351 . Both the cylinder 352 and the guide rod 353 can be arranged on the plate body 370 .

It can be understood that the rotation of the main shaft 310 and the swing of the swing arm 320 do not interfere with each other. In some other embodiments, the rotation of the gluing roller 330 can also be realized by a driving member disposed on the first end 321 of the swing arm 320 without connecting the main shaft 310 and the gluing roller 330 through the transmission member 312 .
