[0001] The present application relates to the technical field of lithium battery equipment, in particular to a tape bonding device and a tape bonding equipment. BACKGROUND

[0002] In the manufacturing process of lithium ion batteries, after the lamination process is completed, the battery cell usually needs to be wrapped with a layer of blue film (insulating tape) on its periphery to improve the insulation performance of the battery cell and enhance its mechanical strength and chemical protection ability. The traditional tape bonding device usually adopts an upper and lower opposed roller structure, and the battery cell and the blue film pass through the gap between the rollers synchronously, and the blue film is bonded to the surface of the battery cell under the action of the roller.

[0003] However, the battery cell usually has a large thickness (especially the battery cell of a large-capacity solid-state battery), and the contact mode of the traditional roller can only effectively press the large area of the battery cell, and the bonding effect of the side area is poor. This may cause the blue film to warp on the side of the battery cell, not to be tightly bonded, or even not to be covered locally, thereby affecting the overall insulation performance and long-term reliability of the battery cell. SUMMARY

[0004] Therefore, it is necessary to provide a tape bonding device and a tape bonding equipment capable of improving the tape bonding effect in view of the above problems.

[0005] A tape bonding device, comprising a side pressing mechanism, a tape suction plate and a first lifting mechanism; the side pressing mechanism comprises a first side pressing piece, a second side pressing piece and a side pressing driving piece, the first side pressing piece and the second side pressing piece are in transmission connection with the side pressing driving piece; the tape suction plate is located between the first side pressing piece and the second side pressing piece.

[0006] In one embodiment, a support frame connected with the first lifting mechanism is further included, and the side pressing mechanism is installed on the support frame.

[0013] In one of the embodiments, a buffer assembly is arranged between the support frame and the glue sucking plate, and the buffer assembly is connected to the glue sucking plate through the support member.

[0014] In one of the embodiments, the glue sucking plate is extended between or flush with the first side pressing member and the second side pressing member under the action of the buffer assembly.

[0015] In one of the embodiments, the glue sucking plate is capable of retracting relative to the first side pressing member and the second side pressing member against the force of the buffer assembly.

[0016] In one of the embodiments, a large plate is further included, the first lifting mechanism is fixed to the large plate, and the support frame is slidably mounted to the large plate.

The glue sucking plate keeps abutting against the large area of the battery cell, and the first side pressing member and the second side pressing member can press down the part of the adhesive tape extending out of the edge of the battery cell. Then, the first side pressing member and the second side pressing member are brought close to each other by the side pressing driving member, so as to stick the adhesive tape on the side area of the battery cell. It can be seen that the adhesive tape sticking apparatus and the glue sticking device can effectively stick the adhesive tape on the large area and the side area, and thus can significantly improve the sticking effect.

[0030] Please refer to Figure 1 and Figure 3 , the present application provides a kind of adhesive tape bonding device 200 and pasting equipment 10.Therein, pasting equipment 10 includes adhesive tape preparation device 100, adhesive tape bonding device 200 and pasting support device 300.

[0031] Adhesive tape preparation device 100 is used to provide the adhesive tape 30 of preset length;Pasting support device 300 includes pasting table 310, and pasting table 310 can carry the battery cell 20 to be pasted;Adhesive tape bonding device 200 can be pasted on the surface of the battery cell 20 carried in pasting table 310 by the adhesive tape 30 provided by adhesive tape preparation device 100.The battery cell 20 includes large area and side edge area, and the length and width of adhesive tape 30 generally need to be greater than the length and width of battery cell 20, so that adhesive tape 30 can better cover the large area and side edge area of battery cell 20.

[0032] Please refer to Figure 2The tape bonding device 200 in one embodiment of the present application comprises a support frame 210, a side pressing mechanism 220, a suction plate 230 and a first lifting mechanism 240.

[0033] The support frame 210 can provide a larger installation space for the side pressing mechanism 220, the suction plate 230 and the like. The first lifting mechanism 240 is connected with the support frame 210, and the first lifting mechanism 240 can drive the support frame 210 to lift. The lifting direction of the first lifting mechanism 240 is generally perpendicular to the suction surface of the suction plate 230, and is generally vertical. While the support frame 210 is lifting, the side pressing mechanism 220 and the suction plate 230 can be lifted. Similarly, the first lifting mechanism 240 can drive the support frame 210 by means of a pneumatic cylinder, an electric cylinder or a motor threaded screw pair, and the specific form is not limited. Of course, the support frame 210 can not be additionally provided, and the first lifting mechanism 240 can directly drive the side pressing mechanism 220 and the suction plate 230 to lift.

[0034] In this embodiment, the tape bonding device 200 further comprises a large plate 260, the first lifting mechanism 240 is fixed to the large plate 260, and the support frame 210 is slidably installed on the large plate 260. The large plate 260 supports the first lifting mechanism 240 and the support frame 210 and the like, and the support frame 210 is slidably installed on the large plate 260 by means of a guide rail and a sliding block, so that the stability can be maintained during the lifting of the support frame 210 by the first lifting mechanism 240.

[0035] The side pressing mechanism 220 comprises a first side pressing piece 221, a second side pressing piece 222 and a side pressing driving piece 223. The first side pressing piece 221 and the second side pressing piece 222 are in transmission connection with the side pressing driving piece 223. More specifically, the first side pressing piece 221 and the second side pressing piece 222 are slidably arranged on the support frame 210, and the side pressing driving piece 223 can drive the first side pressing piece 221 and the second side pressing piece 222 to approach or move away from each other. The side pressing driving piece 223 can be driven by a jaw pneumatic cylinder, and the first side pressing piece 221 and the second side pressing piece 222 are installed on the support frame 210 by means of a guide rail and a sliding block. Of course, in the case where the support frame 210 is not provided, the first side pressing piece 221 and the second side pressing piece 222 can be directly installed on the two jaws of the jaw pneumatic cylinder.

[0036] The suction plate 230 has a suction surface which can suck the adhesive tape 30. Specifically, the suction surface of the suction plate 230 can be provided with a plurality of vacuum suction cups, or a plurality of suction holes can be formed. Moreover, the suction plate 230 is located between the first side pressing piece 221 and the second side pressing piece 222. The suction plate 230 can be directly installed on the support frame 210, or can be installed on the large plate 260 and connected with the support frame 210, or can be installed on the side pressing mechanism 220.

[0037] In the process of pasting the adhesive tape 30 on the battery cell 20, the adhesive tape 30 provided by the adhesive tape providing device 100 is first taken by the adhesive plate 230. Then, the adhesive plate 230 is moved above the adhesive tape pasting table 310, and the adhesive plate 230 and the side pressing mechanism 220 are jointly moved toward the adhesive tape pasting table 310 by the first lifting mechanism 240 driving the support frame 210, until the adhesive plate 230 presses and holds the taken adhesive tape 30 on the large area of the battery cell 20, as shown in Fig. 2(a). The adhesive tape 30 can extend beyond the edge of the battery cell 20. Figure 3

[0038] The adhesive plate 230 abuts against the large area of the battery cell 20, so that the adhesive tape 30 is pasted on the large area of the battery cell 20, and the first side pressing piece 221 and the second side pressing piece 222 can press down the part of the adhesive tape 30 extending beyond the edge of the battery cell 20. Then, the first side pressing piece 221 and the second side pressing piece 222 are brought close to each other by the side pressing driving piece 223, so that the adhesive tape 30 is pasted on the side edge area of the battery cell 20, as shown in Fig. 2(b). It can be seen that the adhesive tape pasting device 200 can effectively paste the adhesive tape 30 on the large area and the side edge area, so that the pasting effect can be significantly improved. Figure 3

[0039] The battery cell 20 is carried on the adhesive tape pasting table 310, and one side of the battery cell 20 is blocked by the adhesive tape pasting table 310. The adhesive tape pasting device 200 can take one adhesive tape 30 at a time, and paste the taken adhesive tape 30 on the upward side of the battery cell 20. Therefore, after the pasting operation on the upward side of the battery cell 20 on the adhesive tape pasting table 310, the battery cell 20 needs to be turned over, so that the side originally blocked by the adhesive tape pasting table 310 faces upward. As shown in Figs. 2(c) to 2(e), the battery cell 20 on the adhesive tape pasting table 310 is turned over, and the adhesive tape pasting device 200 repeats the above pasting process to paste the adhesive tape 30 on the other side of the battery cell 20. In the pasting process, the battery cell 20 only needs to bear the pressure of the adhesive plate 230, and the pressure can be controlled in a small range, so that the battery cell 20 can be effectively prevented from being damaged. Figure 3

[0040] In the embodiment, the adhesive plate 230 can be lifted relative to the first side pressing piece 221 and the second side pressing piece 222. Moreover, the lifting direction of the adhesive plate 230 is consistent with the lifting direction of the support frame 210 driven by the first lifting mechanism 240, which is generally the vertical direction. Specifically, the first side pressing piece 221 and the second side pressing piece 222 can be fixed relative to the support frame 210 along the vertical direction, and the adhesive plate 230 can be lifted relative to the support frame 210 along the vertical direction; or the adhesive plate 230 can be fixed relative to the support frame 210 along the vertical direction, and the first side pressing piece 221 and the second side pressing piece 222 can be lifted relative to the support frame 210 along the vertical direction.

[0041] ​​​When the tape adhering device 200 is not started to adhere the tape, the suction plate 230 is extended between the first side pressing member 221 and the second side pressing member 222 or is flush with the lower edges of the first side pressing member 221 and the second side pressing member 222. In this way, the suction plate 230 can easily suck the tape 30. Moreover, during the process that the first lifting mechanism 240 drives the support frame 210 to descend to adhere the tape, the tape 30 sucked by the suction plate 230 will first contact the large area of the battery cell 20 and be pressed on the large area by the suction plate 230; then, the suction plate 230 keeps abutting against the large area, and the first side pressing member 221 and the second side pressing member 222 descend relative to the suction plate 230, so that the part of the tape 30 extending out of the edge of the battery cell 20 can be pressed down. In this way, the tape 30 can be adhered to the large area and the side edge area of the battery cell 20 in sequence, so that the tape 30 can be effectively stretched, thereby avoiding the tape 30 from being wrinkled.

[0042] Specifically, in the embodiment, the first side pressing member 221 and the second side pressing member 222 are both provided in the form of long strip-shaped plates and extend along the edges of the suction plate 230. The first side pressing member 221 and the second side pressing member 222 can be in the form of rods or strip-shaped plates, so that the contact area with the tape 30 is large. During the process that the part of the tape 30 extending out of the edge of the battery cell 20 is pressed down, the tape 30 can be effectively stretched, thereby further avoiding the tape 30 from being wrinkled.

[0043] In the embodiment, the suction plate 230 can slide relative to the support frame 210, and the tape adhering device 200 further comprises a buffer assembly 250 provided between the support frame 210 and the suction plate 230.

[0044] Specifically, the suction plate 230 can be slidably mounted on the support frame 210 or can be slidably mounted on the large plate 260. The buffer assembly 250 can provide elastic force by using a buffer air cylinder, an air spring or a metal spring, as long as it can be elastically deformed under external force. When the buffer assembly 250 uses a buffer air cylinder, the buffer air cylinder is fixed to the support frame 210, and the piston rod thereof is connected with the suction plate 230.

[0045] More specifically, the suction plate 230 is extended between the first side pressing member 221 and the second side pressing member 222 or is flush with the first side pressing member 221 and the second side pressing member 222 under the action of the buffer assembly 250, and the suction plate 230 can overcome the force of the buffer assembly 250 to retract relative to the first side pressing member 221 and the second side pressing member 222.

[0046] In the process that the first lifting mechanism 240 drives the support frame 210 to move the suction plate 230 and the side pressing mechanism 220 together towards the tape sticking table 310, the suction plate 230 can first press the adhesive tape 30 on the large area of the battery cell 20. Then, as the first lifting mechanism 240 continues to drive the support frame 210, the suction plate 230 retracts relative to the first side pressing piece 221 and the second side pressing piece 222 against the force of the buffer assembly 250, so as to keep abutting with the large area of the battery cell 20; and the first side pressing piece 221 and the second side pressing piece 222 continue to descend, so as to press down the part of the adhesive tape 30 extending out of the edge of the battery cell 20. That is, the first side pressing piece 221 and the second side pressing piece 222 are fixedly arranged on the support frame 210 along the vertical direction, so as to facilitate simplifying the structure of the adhesive tape sticking device 200.

[0047] Moreover, the buffer assembly 250 can also play a buffering role at the moment when the suction plate 230 contacts the battery cell 20, so as to avoid the hard contact between the suction plate 230 and the battery cell 20, and further prevent the damage to the battery cell 20 in the process of sticking the adhesive tape.

[0048] It should be noted that, in other embodiments, the first side pressing piece 221 and the second side pressing piece 222 can also be installed on the support frame 210 in a liftable manner; after the suction plate 230 presses the adhesive tape 30 on the large area of the battery cell 20, the first lifting mechanism 240 stops driving the support frame 210, and the first side pressing piece 221 and the second side pressing piece 222 descend relative to the support frame 210 to press down the part of the adhesive tape 30 extending out of the edge of the battery cell 20.

[0049] Further, in the embodiment, the adhesive tape sticking device 200 further comprises a support piece 270, which can slide relative to the support frame 210, and the suction plate 230 is fixed on the support piece 270.

[0050] Specifically, the support piece 270 can adopt a long strip-shaped cantilever structure, and the support piece 270 can be installed on the support frame 210 in a way that the guide rail cooperates with the sliding block, or can be installed on the large plate 260, so that the suction plate 230 can slide relative to the support frame 210. The support piece 270 can provide better support for the suction plate 230, so as to facilitate the installation of the suction plate 230. More specifically, the buffer assembly 250 is connected with the suction plate 230 through the support piece 270.

[0051] The adhesive tape attaching device 200 and the adhesive tape attaching apparatus 10 can first suck the adhesive tape 30 by the suction plate 230, then drive the support frame 210 to move the suction plate 230 and the side pressing mechanism 220 together toward the battery cell 20 to be attached by the first lifting mechanism 240, until the suction plate 230 holds the adhesive tape 30 sucked on the large area of the battery cell 20. The suction plate 230 and the large area of the battery cell 20 are in abutment, and the first side pressing piece 221 and the second side pressing piece 222 can press down the part of the adhesive tape 30 extending out of the edge of the battery cell 20. Then, the first side pressing piece 221 and the second side pressing piece 222 are driven by the side pressing driving piece 223 to move close to each other, so that the adhesive tape 30 can be attached to the side edge area of the battery cell 20. It can be seen that the adhesive tape attaching device 200 and the adhesive tape attaching apparatus 10 can effectively attach the adhesive tape 30 to the large area and the side edge area, so as to significantly improve the adhesive effect.

[0052] The technical features of the above-described embodiments can be combined in any manner. To make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present disclosure.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present disclosure, some modifications and improvements can be made, which are within the scope of the present disclosure.
