Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5, the present utility model provides a technical solution: a tape sticking device for a lithium-ion battery sheet making machine, including an adsorption assembly 100 for fixing the cut tape, which includes an adsorption seat 101 and two rectangular openings 102 opened on the side surface of the adsorption seat 101. A vacuum chamber 103 is opened inside the adsorption seat 101, and a plurality of suction holes 104 communicating with the vacuum chamber 103 are evenly opened on the side surface of the adsorption seat 101. A negative pressure pump 106 communicating with the vacuum chamber 103 is arranged on the front surface of the adsorption seat 101;

[0030] The tape sticking assembly 200 includes a hydraulic rod 201 arranged on the side surface of the adsorption seat 101 and an installation frame 202 fixed on the telescopic end of the hydraulic rod 201. The installation frame 202 has a structure with an open right side, and two symmetrical U-shaped pushing frames 203 are arranged on the inner wall of the installation frame 202. A tape sticking roller 204 is rotatably arranged on the inner wall of the U-shaped pushing frame 203, and the tape sticking roller 204 is in rolling connection with the inner wall of the rectangular opening 102.

[0031] For this tape sticking device of the lithium-ion battery sheet making machine, by setting the adsorption assembly 100 and the tape sticking assembly 200, when the device sticks tape to the side of the lithium-ion battery pack, it can roll and attach the top and bottom ends of the tape to the upper and lower surfaces of the lithium-ion battery pack, thereby realizing the three-sided tape sticking operation on the side of the lithium-ion battery pack, and effectively solving the defect in the prior art that the tape cannot be simultaneously attached to the side and the upper and lower surfaces of the battery pack.

[0032] Refer to Figure 1 , mounting rods 105 are fixedly arranged on both the upper surface and the lower surface of the adsorption seat 101. One ends of the two mounting rods 105 far away from the adsorption seat 101 are fixedly connected to the frame of the lithium-ion battery sheet making machine, and the hydraulic rod 201 is fixed on the frame of the lithium-ion battery sheet making machine through bolts, which is convenient for the installation and disassembly of this tape sticking device.

[0033] Refer to Figure 2-5 , a limiting assembly 300 for limiting the tape when the tape is attached to the surface of the lithium-ion battery pack is arranged inside the installation frame 202, which is convenient for making the tape sticking roller 204 tightly attached to the surface of the lithium-ion battery pack during the tape sticking process.

[0034] Refer to Figure 2-5 , the limiting assembly 300 includes rotating shafts 301 rotatably arranged on the inner wall of the installation frame 202 and corresponding to the two U-shaped pushing frames 203 respectively. A rotating plate 302 is fixedly arranged on the surface of the rotating shaft 301, and the end of the rotating plate 302 is fixedly connected to the end of the U-shaped pushing frame 203. The arrangement of the rotating shaft 301 makes the connection relationship between the U-shaped pushing frame 203 and the installation frame 202 a rotational connection, thus facilitating the transformation of the position of the tape sticking roller 204.

[0035] See also Figure 2-5 Three springs 303 are equidistantly fixed at the other end of the rotating plate 302, and an adjustment plate 304 is fixed at one end of the three springs 303 away from the rotating plate 302. The setting of the springs 303 can enable the glue roller 204 to quickly restore to a horizontal state after the glue is completed, thereby facilitating the glue roller 204 to smoothly enter the rectangular opening 102.

[0036] See also Figure 3-5 The limiting assembly 300 further includes a square cylinder 305 fixedly mounted on the inner wall of the mounting frame 202, and a fixed cylinder 306 fixedly mounted on the side of the square cylinder 305.

[0040] During operation, the negative pressure pump 106 can be started to suck air into the vacuum chamber 103, so that the suction holes 104 on the side of the adsorption seat 101 can effectively adsorb and fix the cut tape, and then the lithium-ion battery pack is placed on the side of the adsorption seat 101, and the hydraulic rod 201 is started. The extension of the hydraulic rod 201 drives the installation frame 202 to move to the right, thereby driving the two U-shaped pushing racks 203 to move to the right, driving the two glue rollers 204 to slide on the inner wall of the rectangular opening 102, and after leaving the rectangular opening 102, the negative pressure pump 106 is turned off. At this time, the glue rollers 204 continue to move, and the top and bottom ends of the tape can be rolled and attached to the upper and lower surfaces of the lithium-ion battery pack, thereby realizing the gluing operation on the three sides of the lithium-ion battery pack, thereby effectively solving the problem in the prior art that the tape cannot be attached at the same time. The defects on the side and upper and lower surfaces of the battery pack are eliminated; at the same time, in the process of the installation frame 202 moving toward the adsorption seat 101, the pressure rod 3011 can drive the sealing piston column 3010 to slide on the inner wall of the fixed cylinder 306, and press the air in the fixed cylinder 306 into the square cylinder 305 through the inflation hole 3013, so that the two sealing piston plates 307 in the square cylinder 305 move toward each other at the same time, thereby driving the two push rods 308 to push the adjustment plate 304, and under the action of the rotating shaft 301, the glue roller 204 at the end of the U-shaped pushing rack 203 always presses the tape to the surface of the lithium-ion battery pack, so that the glue sticking device can stick the tape neatly and flatly to the surface of the lithium-ion battery pack, and can perform glue sticking operations on lithium-ion battery packs of different thicknesses, and is more practical.

[0041] To sum up, the device can roll and adhere the top and bottom ends of the tape to the upper and lower surfaces of the lithium-ion battery pack, thereby realizing the gluing operation on the three sides of the lithium-ion battery pack, and effectively solving the defect of the prior art that the tape cannot be simultaneously attached to the side and the upper and lower surfaces of the battery pack, and can make the gluing roller 204 at the end of the U-shaped pushing rack 203 always press the tape to the surface of the lithium-ion battery pack, so that the gluing device can adhere the tape neatly and flatly to the surface of the lithium-ion battery pack, and can perform gluing operations on lithium-ion battery packs of different thicknesses, and is highly practical.
