Description

Technical Field

[0001] This utility model relates to the field of lithium battery equipment technology, and in particular to a tape bonding device and tape application equipment. Background Technology

[0002] In the manufacturing process of lithium-ion batteries, after the cells are stacked, a layer of blue film (insulating tape) is usually wrapped around their outer periphery to improve the insulation performance of the cells and enhance their mechanical strength and chemical protection capabilities. Traditional tape-applying devices typically use an upper and lower opposing pressure roller structure. The cells and the blue film pass through the gap between the pressure rollers simultaneously, and the blue film is adhered to the surface of the cells under the pressure of the rollers.

[0003] However, battery cells typically have a significant thickness (especially those in high-capacity solid-state batteries), and traditional pressure rollers can only effectively press the large surface areas of the cell, resulting in poor adhesion to the side areas. This can lead to problems such as warping, loose adhesion, or even partial uncovering of the blue film on the sides of the cell, thus affecting the overall insulation performance and long-term reliability of the cell. Utility Model Content

[0004] Therefore, it is necessary to provide a tape application device and tape application equipment that can improve the tape application effect in order to address the above problems.

[0005] A tape application device includes a side-pressing mechanism, a suction plate, and a first lifting mechanism; the side-pressing mechanism includes a first side-pressing member, a second side-pressing member, and a side-pressing driving member, wherein the first side-pressing member and the second side-pressing member are operatively connected to the side-pressing driving member; the suction plate is located between the first side-pressing member and the second side-pressing member.

[0006] In one embodiment, a support frame connected to the first lifting mechanism is also included, and the side pressing mechanism is mounted on the support frame.

[0007] In one embodiment, the first side pressure member and the second side pressure member are slidably disposed opposite to each other on the support frame.

[0008] In one embodiment, the side pressure drive can drive the first side pressure member and the second side pressure member to move closer to or further away from each other.

[0009] In one embodiment, the adhesive suction plate is capable of moving up and down relative to the first side pressure member and the second side pressure member.

[0010] In one embodiment, the device further includes a support frame connected to the first lifting mechanism, and the tape application device further includes a buffer assembly disposed between the support frame and the adhesive suction plate.

[0011] In one embodiment, the buffer assembly includes a buffer cylinder fixed to the support frame, and the piston rod of the buffer cylinder is connected to the adhesive suction plate.

[0012] In one embodiment, a support member is also included, which is slidable relative to the support frame, and the adhesive suction plate is fixed to the support member.

[0013] In one embodiment, a buffer assembly is provided between the support frame and the adhesive suction plate, and the buffer assembly is connected to the adhesive suction plate through the support member.

[0014] In one embodiment, the adhesive-absorbing plate extends out from between the first side pressure member and the second side pressure member or is flush with the first side pressure member and the second side pressure member under the action of the buffer assembly.

[0015] In one embodiment, the adhesive-absorbing plate is able to overcome the force of the buffer assembly and retract relative to the first and second side pressure members.

[0016] In one embodiment, a large plate is also included, the first lifting mechanism is fixed to the large plate, and the support frame is slidably mounted on the large plate.

[0017] In one embodiment, both the first and second side pressure members are configured as long strips of plates and extend along the edge of the adhesive absorption plate.

[0018] An adhesive applicator includes an adhesive tape application device as described in any of the preferred embodiments above.

[0019] The aforementioned tape application device and equipment first employ a suction plate to pick up the tape, then a first lifting mechanism drives the suction plate and side pressing mechanism to move towards the battery cell to be coated, until the suction plate presses the picked-up tape onto the large surface area of ​​the battery cell. The suction plate remains in contact with the large surface area of ​​the battery cell, while the first and second side pressing members press down the portion of the tape extending beyond the edge of the battery cell. The side pressing drive then moves the first and second side pressing members closer together, thus adhering the tape to the side area of ​​the battery cell. Therefore, the aforementioned tape application device and equipment can effectively adhere the tape to both the large surface area and the side area, significantly improving the coating effect.

[0028] Please see Figure 1 and Figure 3 This utility model provides an adhesive tape bonding device 200 and an adhesive application equipment 10. The adhesive application equipment 10 includes an adhesive preparation device 100, an adhesive tape bonding device 200, and an adhesive application support device 300.

[0029] The adhesive preparation device 100 provides adhesive tape 30 of a preset length; the adhesive application support device 300 includes an application table 310, which can support the battery cell 20 to be adhesiveped; the adhesive tape application device 200 applies the adhesive tape 30 provided by the adhesive preparation device 100 to the surface of the battery cell 20 supported on the application table 310. The battery cell 20 includes a large surface area and side areas, and the length and width of the adhesive tape 30 generally need to be greater than the length and width of the battery cell 20 so that the adhesive tape 30 can better cover the large surface area and side areas of the battery cell 20.

[0030] Please refer to the following: Figure 2In one embodiment of the present invention, the tape bonding device 200 includes a support frame 210, a side pressing mechanism 220, a suction plate 230, and a first lifting mechanism 240.

[0031] The support frame 210 provides ample installation space for the side-pressing mechanism 220, the adhesive suction plate 230, and other components. The first lifting mechanism 240 is connected to the support frame 210 and drives the support frame 210 to rise and fall. The lifting direction of the first lifting mechanism 240 is generally perpendicular to the suction surface of the adhesive suction plate 230, roughly vertical. Simultaneously with the lifting of the support frame 210, it also drives the side-pressing mechanism 220 and the adhesive suction plate 230 to rise and fall. Similarly, the first lifting mechanism 240 can be driven by a cylinder, electric cylinder, or a lead screw assembly, etc., with no specific limitation on its form. Alternatively, the support frame 210 may not be separately provided, and the first lifting mechanism 240 can directly drive the side-pressing mechanism 220 and the adhesive suction plate 230 to rise and fall.

[0032] Specifically, in this embodiment, the tape application device 200 further includes a large plate 260, a first lifting mechanism 240 fixed to the large plate 260, and a support frame 210 slidably mounted on the large plate 260. The large plate 260 supports the first lifting mechanism 240 and the support frame 210, etc. The support frame 210 can be slidably mounted on the large plate 260 through the cooperation of a guide rail and a slider, thus maintaining high stability during the process of the first lifting mechanism 240 driving the support frame 210 to rise and fall.

[0033] The side-pressing mechanism 220 includes a first side-pressing member 221, a second side-pressing member 222, and a side-pressing drive member 223. The first side-pressing member 221 and the second side-pressing member 222 are connected to the side-pressing drive member 223 in a driving manner. More specifically, the first side-pressing member 221 and the second side-pressing member 221 are slidably disposed opposite to each other on the support frame 210, and the side-pressing drive member 223 can drive the first side-pressing member 221 and the second side-pressing member 222 to move closer or further apart. The side-pressing drive member 223 can be driven by a gripper cylinder or similar device, while the first side-pressing member 221 and the second side-pressing member 222 can be mounted on the support frame 210 via a guide rail and slider. Alternatively, without the support frame 210, the first side-pressing member 221 and the second side-pressing member 222 can be directly mounted on the two grippers of the gripper cylinder.

[0034] The adhesive suction plate 230 has an adsorption surface capable of absorbing the adhesive tape 30. Specifically, the adsorption surface of the adhesive suction plate 230 can be provided with multiple vacuum suction cups or have multiple adsorption holes. Furthermore, the adhesive suction plate 230 is located between the first side pressure member 221 and the second side pressure member 222. The adhesive suction plate 230 can be directly mounted on the support frame 210, mounted on the large plate 260 and connected to the support frame 210, or mounted on the side pressure mechanism 220.

[0035] When applying adhesive to the battery cell 20, the adhesive suction plate 230 first picks up the adhesive tape 30 provided by the adhesive preparation device 100; then the adhesive suction plate 230 is moved above the adhesive application table 310, and the first lifting mechanism 240 drives the support frame 210 to move the adhesive suction plate 230 and the side pressing mechanism 220 together toward the adhesive application table 310 until the adhesive suction plate 230 presses the picked-up adhesive tape 30 onto the large surface area of ​​the battery cell 20, specifically as follows: Figure 3 As shown in (a), the tape 30 can generally extend beyond the edge of the battery cell 20.

[0036] The adhesive suction plate 230 maintains contact with the large surface area of ​​the battery cell 20 to ensure that the tape 30 adheres to the large surface area of ​​the battery cell 20. The first side pressure member 221 and the second side pressure member 222 press down the portion of the tape 30 extending beyond the edge of the battery cell 20. Then, the side pressure drive member 223 moves the first side pressure member 221 and the second side pressure member 222 closer together, thus adhering the tape 30 to the side area of ​​the battery cell 20. Specifically, as shown... Figure 3 As shown in (b), the tape bonding device 200 described above can effectively bond the tape 30 to the large surface area and the side area, thus significantly improving the bonding effect.

[0037] The battery cell 30 is supported on the adhesive application table 310, with one side of it covered by the table 310. The tape application device 200 can pick up one piece of tape 30 at a time and apply it to the upward-facing side of the battery cell 20. Therefore, after applying tape to the upward-facing side of the battery cell 20 on the adhesive application table 310, the battery cell 20 needs to be flipped over so that the side previously covered by the adhesive application table 310 is facing upwards. Figure 3 As shown in (c) to (e), the battery cell 20 on the adhesive application table 310 is flipped over, and the adhesive tape application device 200 repeats the above adhesive application process to apply adhesive to the other side of the battery cell 20. During the adhesive application process, the battery cell 20 only needs to be subjected to the pressure of the adhesive suction plate 230, and this pressure can be controlled within a small range, thus effectively avoiding damage to the battery cell 20.

[0038] In this embodiment, the adhesive suction plate 230 can be raised and lowered relative to the first side pressure member 221 and the second side pressure member 222. Furthermore, the raising and lowering direction of the adhesive suction plate 230 is consistent with the raising and lowering direction of the support frame 210 driven by the first lifting mechanism 240, generally in the vertical direction. Specifically, the first side pressure member 221 and the second side pressure member 222 can be fixed vertically relative to the support frame 210, while the adhesive suction plate 230 can be raised and lowered vertically relative to the support frame 210; alternatively, the adhesive suction plate 230 can be fixed vertically relative to the support frame 210, while the first side pressure member 221 and the second side pressure member 222 can be raised and lowered vertically relative to the support frame 210.

[0039] When the tape application device 200 is not activated, the suction plate 230 extends from between the first side pressure member 221 and the second side pressure member 222 or is flush with the lower edges of the first side pressure member 221 and the second side pressure member 222. This facilitates the suction plate 230 in absorbing the tape 30. Moreover, during the process of the first lifting mechanism 240 driving the support frame 210 to descend to achieve tape application, the tape 30 absorbed by the suction plate 230 will first contact the large surface area of ​​the battery cell 20 and be pressed onto the large surface area by the suction plate 230; then, the suction plate 230 remains in contact with the large surface area, while the first side pressure member 221 and the second side pressure member 222 descend relative to the suction plate 230, thereby pressing down the portion of the tape 30 extending beyond the edge of the battery cell 20. In this way, the tape 30 can be applied to the large surface area and the side area of ​​the battery cell 20 successively, so the tape 30 can be effectively stretched, thereby avoiding wrinkles in the tape 30.

[0040] Specifically, in this embodiment, both the first side pressing member 221 and the second side pressing member 222 are configured as long strip-shaped plates extending along the edge of the adhesive absorption plate 230. The first side pressing member 221 and the second side pressing member 222 can be rod-shaped or strip-shaped plates, thus having a large contact area with the tape 30. During the process of pressing down the portion of the tape 30 extending beyond the edge of the battery cell 20, the tape 30 can be effectively unfolded, thereby further preventing wrinkles from forming on the tape 30.

[0041] In this embodiment, the adhesive suction plate 230 can slide relative to the support frame 210, and the tape application device 200 also includes a buffer assembly 250, which is disposed between the support frame 210 and the adhesive suction plate 230.

[0042] Specifically, the adhesive suction plate 230 can be slidably mounted on the support frame 210 or on the large plate 260. The buffer assembly 250 can use a buffer cylinder, gas spring, or metal spring to provide elastic force, as long as it can undergo elastic deformation under external force. When the buffer assembly 250 uses a buffer cylinder, the buffer cylinder is fixed to the support frame 210, and its piston rod is connected to the adhesive suction plate 230.

[0043] More specifically, under the action of the buffer assembly 250, the adhesive suction plate 230 extends out from between the first side pressure member 221 and the second side pressure member 222 or is flush with the first side pressure member 221 and the second side pressure member 222, and the adhesive suction plate 230 can overcome the force of the buffer assembly 250 and retract relative to the first side pressure member 221 and the second side pressure member 222.

[0044] As the first lifting mechanism 240 drives the support frame 210 to move the adhesive suction plate 230 and the side pressing mechanism 220 together toward the adhesive application table 310, the adhesive suction plate 230 first presses the adhesive tape 30 onto the large surface area of ​​the battery cell 20. Then, as the first lifting mechanism 240 continues to drive the support frame 210, the adhesive suction plate 230 overcomes the force of the buffer assembly 250 and retracts relative to the first side pressing member 221 and the second side pressing member 222, thus maintaining contact with the large surface of the battery cell 20; while the first side pressing member 221 and the second side pressing member 222 continue to descend, pressing down the portion of the adhesive tape 30 extending beyond the edge of the battery cell 20. In other words, the first side pressing member 221 and the second side pressing member 222 are fixedly mounted vertically relative to the support frame 210, thus simplifying the structure of the adhesive tape application device 200.

[0045] Moreover, the buffer component 250 can also play a buffering role at the moment when the adhesive suction plate 230 comes into contact with the battery cell 20, thereby avoiding hard contact between the adhesive suction plate 230 and the battery cell 20, so as to further prevent damage to the battery cell 20 during the adhesive application process.

[0046] It should be noted that in other embodiments, the first side pressing member 221 and the second side pressing member 222 can also be installed on the support frame 210 in a height-adjustable manner; after the adhesive suction plate 230 presses the tape 30 onto the large area of ​​the battery cell 20, the first lifting mechanism 240 stops driving the support frame 210, and the first side pressing member 221 and the second side pressing member 222 descend relative to the support frame 210 to press down the portion of the tape 30 extending beyond the edge of the battery cell 20.

[0047] Furthermore, in this embodiment, the tape application device 200 also includes a support member 270, which is slidable relative to the support frame 210, and the adhesive suction plate 230 is fixed to the support member 270.

[0048] Specifically, the support member 270 can adopt a long, cantilevered structure. The support member 270 can be installed on the support frame 210 via a guide rail and slider, or it can be installed on the large plate 260, allowing the adhesive suction plate 230 to slide relative to the support frame 210. The support member 270 provides good support for the adhesive suction plate 230, facilitating its installation. More specifically, the buffer assembly 250 is connected to the adhesive suction plate 230 via the support member 270.

[0049] The tape application device 200 and the tape application equipment 10 described above can first have the adhesive tape 30 picked up by the suction plate 230, and then the first lifting mechanism 240 drives the support frame 210 to move the suction plate 230 and the side pressing mechanism 220 together toward the battery cell 20 to be applied, until the suction plate 230 presses the picked-up adhesive tape 30 onto the large surface area of ​​the battery cell 20. The suction plate 230 and the large surface area of ​​the battery cell 20 remain in contact, and the first side pressing member 221 and the second side pressing member 222 can press down the portion of the adhesive tape 30 that extends beyond the edge of the battery cell 20. Then, the side pressing drive member 223 drives the first side pressing member 221 and the second side pressing member 222 to move closer to each other, so that the adhesive tape 30 can be applied to the side area of ​​the battery cell 20. It can be seen that the tape application device 200 and the tape application equipment 10 described above can achieve effective application of the adhesive tape 30 to the large surface area and the side area, thus significantly improving the application effect.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
