[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference Figure 1 as well as Figure 2 As shown, the utility model provides a battery cell tape sticking device, including a tape cutting unit 100, a tape sticking unit 200 and a tape conveying unit 300, wherein:

[0036] The tape conveying unit 300 is used to convey the tape. The tape conveying unit 300 includes a reel 310 and a tensioning assembly 320. The tape is wound on the reel 310, and the tensioning assembly 320 is used to maintain the tension of the tape. In the embodiment provided in the present application, the reel 310 is used to wind the tape. As the tape pasting unit 200 continues to paste the tape on the battery cell, the tape on the reel 310 will continue to decrease and become loose. Therefore, the tensioning assembly 320 is provided so that the tape can always maintain a certain tension, thereby ensuring the continuous transmission of the tape.

[0037] The tape cutting unit 100 is used to cut the tape. The tape cutting unit 100 includes a clamping assembly 110 and a cutting assembly 120. The clamping assembly 110 is used to clamp the tape conveyed by the tape conveying unit 300 and drive the tape to move along the first direction D1. The cutting assembly 120 is used to cut the tape. In the embodiment provided by the present application, the first direction D1 is the gravity direction. After the clamping assembly 110 clamps the tape of the tape conveying unit 300 and drives the tape upward to the position where the tape is pasted, the cutting assembly 120 cuts the tape to be pasted.

[0038] The tape pasting unit 200 includes a first driving component 210 and a pasting plate 220. The first driving component 210 can drive the pasting plate 220 to move back and forth along the second direction D2 and the third direction D3. The pasting plate 220 is provided with a pasting component 230, and the pasting component 230 is used to paste the tape on the side of the battery cell. In the embodiment provided in the present application, the second direction D2 is the direction in which the pasting plate 220 approaches or moves away from the battery cell, and the third direction D3 is perpendicular to the second direction D2, and is the direction in which the pasting plate 220 approaches or moves away from the tape cutting unit 100. The first driving component 210 drives the pasting plate 220 to move along the second direction D2 to move the pasting component 230 to the battery cell position where the tape needs to be pasted, and drives the pasting plate 220 to move along the third direction D3, so that the tape cutting unit 100 can cut the tape that needs to be pasted.

[0039] Reference Figure 3 as well as Figure 4 As shown, the clamping assembly 110 includes a first gripper 111, a second gripper 112 and a first driving member. The first gripper 111 is used to grip the tape conveyed by the tape conveying unit 300, the second gripper 112 is used to grip the tape gripped by the first gripper 111, and the first driving member is used to drive the second gripper 112 to move along the first direction D1. In the embodiment provided by the present application, the first gripper 111 grips the end of the tape wound on the reel 310, the second gripper 112 moves down to the gripping position of the first gripper 111 under the action of the first driving member, and then grips the end of the tape, and then moves up again to the position of applying the tape under the action of the first driving member, and then the cutting assembly 120 cuts the tape, at which time the first gripper 111 is still gripped at the cut position of the tape, so that the second gripper 112 can grip the tape for the next time, so that the tape can be continuously conveyed.

[0040] In a feasible implementation, the first driving member includes a first motor 113, a first screw rod 114 and a first screw rod nut 115. The output shaft end of the first motor 113 is connected to the first screw rod 114, and the second gripper 112 is connected to the first screw rod nut 115. When the first motor 113 is started, it drives the first screw rod 114 to rotate. Under the cooperation of the first screw rod nut 115 and the first screw rod 114, the first screw rod nut 115 moves up and down along the first screw rod 114, thereby driving the second gripper 112 to move up and down. In other implementations, the first driving member may adopt other structures or components that can drive the second gripper 112 to move up and down, which is not limited here.

[0041] Furthermore, the cutting assembly 120 includes a cutter 121 and a first cylinder 122. The cutter 121 is connected to the end of the piston rod of the first cylinder 122. The first cylinder 122 can drive the cutter 121 to move along the second direction D2. The cutting assembly 120 is arranged in a position parallel to the tape pasting portion 200. The first cylinder 122 is started to drive the cutter 121 to move toward or away from the tape. After the second gripper 112 drives the tape to the tape pasting position, the first cylinder 122 drives the cutter 121 to approach the tape to cut the tape. In other embodiments, the cutting assembly 120 can adopt other structures or components that can achieve cutting of the tape, which are not limited here.

[0042] Reference Figure 6 As shown, the pasting component 230 includes a first pickup block 231, a second pickup block 232, a top block 233, and a cylinder module 234, wherein: the first pickup block 231 and the second pickup block 232 are arranged on both sides of the top block 233 along the first direction D1, the first end of the first pickup block 231 and the first end of the second pickup block 232 are both connected to the cylinder module 234, the cylinder module 234 is used to drive the first pickup block 231 and the second pickup block 232 to move towards each other, the second end of the first pickup block 231 and the second end of the second pickup block 232 are both provided with an adsorption member 235, and the adsorption member 235 is used to adsorb the adhesive tape; the pasting plate 220 is provided with a first guide rail 236 and a first slider 237 cooperating with the first guide rail 236, and the top block 233 is connected to the first slider 237.

[0043] In the embodiment provided by the present application, the first pickup block 231 and the second pickup block 232 are respectively arranged on the upper and lower sides of the top block 233, and the adsorption part 235 is a negative pressure adsorption port. Before cutting the tape, the tape is adsorbed by the negative pressure adsorption port, and then through the action of the cylinder module 234, the first pickup block 231 and the second pickup block 232 are simultaneously approached or moved away from the top block 233 to stick the tape to the side of the battery cell. When the tape cutting unit 100 drives the tape to the tape pasting location, the pasting component 230 moves to the tape position under the action of the first driving component 210, and the adsorption member 235 at the second end of the first picking block 231 and the second end of the second picking block 232 simultaneously adsorbs the tape, and then the cutting component 120 cuts the tape. After the tape is cut, the pasting plate 220 continues to move in the direction close to the tape until the top block 233 can support the battery cell. Since the top block 233 is connected to the first slider 237, when the pasting plate 220 continues to move forward, with the cooperation of the first slider 237 and the first guide rail 236, the top block 233 can always support the battery cell but will not push the battery cell. During the movement of the pasting plate 220, the cylinder module 234 drives the first picking block 231 and the second picking block 232 to move in the direction away from each other, so as to achieve the purpose of pasting the tape on the side of the battery cell.

[0044] In a feasible implementation mode, referring to Figure 5 As shown, the first driving assembly 210 includes a second motor 211, a third motor 212, a second screw rod 213, a second screw rod nut 214, a third screw rod 215, a third screw rod nut (not shown in the figure), and a fixed seat 216, wherein: the second motor 211 can drive the pasting plate 220 to reciprocate along the second direction D2, the second motor 211, the second screw rod 213 and the second screw rod nut 214 are arranged on the fixed seat 216, the output shaft end of the second motor 211 is connected to one end of the second screw rod 213, and the pasting plate 220 is connected to the second screw rod nut 214; the third motor 212 can drive the fixed seat 216 to reciprocate along the third direction D3, the output shaft end of the third motor 212 is connected to one end of the third screw rod 215, and the third screw rod nut is connected to the fixed seat 216.

[0045] The second motor 211 is started to rotate the second screw rod 213. Under the cooperation of the second screw rod 213 and the second screw rod nut 214, the second screw rod nut 214 can move along the second screw rod 213, thereby driving the pasting plate 220 to move in the second direction D2. The third motor 212 is started to rotate the third screw rod 215. Under the cooperation of the third screw rod 215 and the third screw rod nut, the third screw rod nut can reciprocate along the third direction D3, thereby driving the fixing seat 216 to move along the third direction D3, and finally realizing the movement of the pasting plate 220 in the third direction D3.

[0046] In other embodiments, the first driving assembly 210 may adopt other structures or components that can drive the adhesive plate 220 to move along the second direction D2 and the third direction D3, which is not limited here.

[0047] Reference Figure 7 as well as Figure 8 As shown, the tensioning assembly 320 includes a first tension wheel 321, a second tension wheel 322, and a second cylinder 323, wherein: the first tension wheel 321 and the second tension wheel 322 are arranged between the reel 310 and the tape cutting unit 100 at intervals, the piston rod end of the second cylinder 323 is connected to the first tension wheel 321, and the second cylinder 323 can drive the first tension wheel 321 to move along the first direction D1. In the embodiment provided by the present application, the tape on the reel 310 passes through the first tension wheel 321 and the second tension wheel 322 in sequence and is clamped by the clamping assembly 110. As the amount of tape decreases, the tension of the tape gradually decreases. The first tension wheel 321 is driven downward by the second cylinder 323, so that the tape can always maintain a certain tension, thereby ensuring the continuous and stable output of the tape.

[0048] Based on the above embodiments, the working process of the battery cell tape pasting device of the present application is as follows: the tape wound on the reel 310 passes around the first tension wheel 321 and the second tension wheel 322 in turn, and is clamped by the first clamp 111, the first motor 113 is started, and the second clamp 112 moves down to clamp the end of the tape. After clamping the tape, the first motor 113 drives the second clamp 112 to move up to the tape pasting position, and then the second motor 211 and the third motor 212 are started to drive the pasting plate 220 to approach the tape until the first pickup block 231 and the third motor 212 are started. The suction piece 235 of the second picking block 232 absorbs the tape, and then the first cylinder 122 is started to drive the cutter 121 to approach the tape and cut the tape. The second motor 211 is continuously started to make the pasting plate 220 continue to move forward so that the top block 233 supports the battery cell. The cylinder module 234 is started to make the first picking block 231 and the second picking block 232 move up and down respectively to stick the tape to the side of the battery cell. During the continuous pasting of the tape, the second cylinder 323 drives the first tension wheel 321 to descend so that the tape always has a certain tension.

[0049] After completing the tape sticking at one of the positions of the battery cell, the battery cell is driven by the driving mechanism to move along its own length direction. When the battery cell reaches the next position where the tape is required, the driving mechanism stops moving, and the battery cell taping device performs the taping operation. After the tape is affixed on one side of the battery cell, the battery cell is driven by the driving mechanism to rotate a certain angle so that a position on the other side of the battery cell where the tape is required faces the battery cell taping device, and the cycle is repeated until all the positions of the battery cell where the tape is required have completed the taping operation. Those skilled in the art can know that the structure of the driving mechanism that drives the battery cell to move linearly and rotate can refer to the relevant structure of the prior art, and will not be elaborated here.

[0050] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
