Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to an adhesive pressing structure, an adhesive tape stabilizing mechanism, and an adhesive application device. Background Technology

[0002] In lithium battery production, an adhesive applicator is typically used to apply adhesive to the batteries. This applicator usually includes an unwinding mechanism, a tape pulling mechanism, a tape securing mechanism, a tape cutting mechanism, and a tape picking mechanism. The unwinding mechanism releases the tape, the tape pulling mechanism pulls the tape along until a sufficient length is produced, the tape securing mechanism stabilizes the tape, the tape cutting mechanism moves towards the tape and cuts it, and the picking mechanism, positioned at the picking position, picks up the cut tape through suction holes on its end face. The tape securing and pulling mechanisms release the tape, and the picking mechanism, carrying the tape detached from the securing and pulling mechanisms, moves to the applicator position on the battery for application. After application, it returns to the picking position to pick up more tape, and this cycle repeats. To prevent scratching the tape, the tape securing mechanism's pressing structure is equipped with deformable components (e.g., rubber sheets). However, these deformable components are consumables and need timely replacement after a period of use. Currently, these components are fixed with screws, making disassembly and replacement extremely inconvenient. Utility Model Content

[0044] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0045] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] like Figure 1 As shown, an embodiment of the present invention provides an adhesive applicator 10. The adhesive applicator 10 includes an unwinding mechanism 12, an adhesive pulling mechanism (not shown), an adhesive tape stabilizing mechanism 14, an adhesive cutting mechanism 16, and an adhesive taking mechanism 18.

[0048] The unwinding mechanism 12 is used to release the tape 10a. The tape pulling mechanism is used to pull the tape 10a out of the unwinding mechanism 12. The tape stabilizing mechanism 14 is used to hold the tape 10a in place to prevent displacement. The tape cutting mechanism 16 is used to cut the tape 10a. The tape picking mechanism 18 can pick up the cut tape 10a. After the tape stabilizing mechanism 14 and the tape pulling mechanism release the tape 10a, the tape picking mechanism 18 moves the tape 10a that has detached from the tape stabilizing mechanism 14 and the tape pulling mechanism to the adhesive application position to apply adhesive to the battery.

[0049] In this embodiment, the adhesive applicator 10 also includes a mounting plate 19. The unwinding mechanism 12, the adhesive pulling mechanism (not shown), the tape stabilizing mechanism 14, the adhesive cutting mechanism 16, and the adhesive taking mechanism 18 are all mounted on the mounting plate 19. This allows the adhesive applicator 10 to have a high degree of integration.

[0050] In this embodiment, the adhesive applicator 10 includes two unwinding mechanisms 12. Each unwinding mechanism 12 is equipped with an adhesive pulling mechanism, an adhesive tape stabilizing mechanism 14, an adhesive cutting mechanism 16, and an adhesive dispensing mechanism 18. This improves battery processing efficiency and reduces battery production costs.

[0051] In this embodiment, the tape stabilizing mechanism 14 includes a pressing structure 14a and a mating structure 14b disposed opposite to each other. The gap between the pressing structure 14a and the mating structure 14b is adjustable to clamp or release the tape 10a passing between the pressing structure 14a and the mating structure 14b.

[0052] In this embodiment, as Figures 2-4 As shown, the adhesive bonding structure 14a includes a mounting base 200 and an adhesive bonding assembly 300. The mounting base 200 has a mounting through hole 210 extending through the mounting base 200. The mounting base 200 has an opening 220 communicating with the mounting through hole 210. The opening 220 extends through the mounting base 200 and is located on one side of the mounting through hole 210.

[0053] The adhesive application assembly 300 includes a mounting member 310 and a deformable member 320 for contacting the adhesive tape 10a. The mounting member 310 includes a connecting portion 312 and a limiting portion 314. The connecting portion 312 is disposed on the mounting through hole 210. The size of the connecting portion 312 is adapted to the size of the opening 220, so that the connecting portion 312 can enter and exit the mounting through hole 210 through the opening 220. The deformable member 320 is located outside the mounting through hole 210 and connected to one end of the connecting portion 312. The limiting portion 314 is limited on the mounting base 200 and connected to the other end of the connecting portion 312. The deformable member 320 has low hardness, which reduces the probability of scratching the adhesive tape 10a. However, the deformable member 320 is a consumable part and needs to be replaced after a period of use. Specifically, the deformable member 320 can be rubber.

[0054] In the aforementioned pressure-bonding structure 14a, when the pressure-bonding assembly 300 is assembled on the mounting base 200, since the size of the connecting part 312 matches the size of the opening 220, the connecting part 312 can be assembled into the mounting through hole 210 through the opening 220. During or after the connecting part 312 is assembled into the mounting through hole 210, the limiting part 314 is positioned on the mounting base 200, thus completing the assembly of the pressure-bonding assembly 300 and the mounting base 200. When it is necessary to replace the deformable part 320, during or after the limiting part 314 is released from the mounting base 200, the connecting part 312 can be removed from the mounting through hole 210 through the opening 220, thus completing the disassembly of the pressure-bonding assembly 300 and the mounting base 200. Compared to the screw-down disassembly method, the disassembly and assembly of the aforementioned adhesive bonding assembly 300 and mounting base 200 is very convenient, solving the technical problems of time-consuming and labor-intensive replacement of the adhesive bonding assembly 300 and low battery processing efficiency / high cost.

[0055] In this embodiment, the limiting part 314 abuts against the mounting base 200 to limit its position on the mounting base 200. This makes it very easy to limit the limiting part 314 to the mounting base 200 and to release the limiting part 314 from the mounting base 200.

[0056] For example, in some embodiments, by controlling the movement of the connecting portion 312 in the first direction, the limiting portion 314 can be positioned on the mounting base 200 and the positioning of the limiting portion 314 on the mounting base 200 can be released. At this time, with... Figure 4 Taking the shown perspective as an example, after the connecting part 312 is assembled into the mounting through hole 210, the connecting part 312 is controlled to move in the first direction (moving downward) so that the limiting part 314 abuts against the mounting base 200, thus completing the assembly of the pressure bonding assembly 300 and the mounting base 200; when it is necessary to replace the deformable part 320, the connecting part 312 is controlled to move in the first direction (moving upward) so that the limiting part 314 is separated from the mounting base 200, and then the connecting part 312 is taken out from the mounting through hole 210 through the opening 220, thus completing the disassembly of the pressure bonding assembly 300 and the mounting base 200.

[0057] In some embodiments, the positions of the limiting part 314 and the mounting base 200 can be adjusted first, and then the mounting member 310 can be pushed in the second direction. While the connecting part 312 is assembled into the mounting through hole 210, the limiting part 314 is pressed against the mounting base 200 under the action of gravity, thus completing the assembly of the pressure bonding assembly 300 and the mounting base 200. When it is necessary to replace the deformable part 320, the mounting member 310 is pushed in the second direction, so that the limiting part 314 is separated from the mounting base 200. At the same time, the connecting part 312 is taken out from the mounting through hole 210 through the opening 220, thus completing the disassembly of the pressure bonding assembly 300 and the mounting base 200.

[0058] It is understood that in other embodiments, when the mounting base 200 is provided with a hole or other mating part that mates with the limiting part 314, the limiting part 314 can be limited to the mounting base 200 by inserting the limiting part 314 into the hole.

[0059] In this embodiment, the end face of the limiting part 314 away from the connecting part 312 is flush with the outer wall of the mounting base 200. In this way, the limiting part 314 can be prevented from protruding outward and interfering with other components, and the limiting part 314 can be prevented from sinking inward and accumulating dust.

[0060] In this embodiment, the side of the connecting portion 312 and the limiting portion 314 exposed from the opening 220 is flush with the outer wall of the mounting base 200. This prevents the connecting portion 312 and the limiting portion 314 from protruding outward and interfering with other components, and also prevents the connecting portion 312 and the limiting portion 314 from sinking inward and accumulating dust.

[0061] In this embodiment, the arrangement direction of the limiting part 314, the connecting part 312, and the deformable member 320 is a first direction. In this first direction, the mounting through hole 210 includes a first hole segment 212 and a second hole segment 214. The inner diameter of the first hole segment 212 is larger than the inner diameter of the second hole segment 214, defining a limiting surface located between the first hole segment 212 and the second hole segment 214. The connecting part 312 is provided on the second hole segment 214. The limiting part 314 abuts against the limiting surface. Thus, at least a portion of the limiting part 314 can be accommodated within the mounting through hole 210. It is understood that in other embodiments, the diameter of the mounting through hole 210 can be the same everywhere, in which case the limiting part 314 can directly abut against the outer wall of the mounting base 200.

[0062] In this embodiment, the outer peripheral wall of the limiting part 314 is adapted to the inner peripheral wall of the first hole segment 214. Specifically, in this embodiment, the distance between the outer peripheral wall of the limiting part 314 and the inner peripheral wall of the first hole segment 214 is very small or even in contact. The mounting base 200 has an auxiliary hole 230 on one side of the first hole segment 212. The auxiliary hole 230 penetrates the inner peripheral wall of the first hole segment 212 and communicates with the first hole segment 212. In this way, deformation of the limiting part 314 and / or the mounting through hole 210 can be prevented, which would make it difficult to insert or remove the limiting part 314.

[0063] In this embodiment, there are multiple auxiliary holes 230, which are arranged at intervals along the circumference of the first hole segment 212. This better prevents deformation of the limiting part 314 and / or the mounting through hole 210, which could make it difficult to insert or remove the limiting part 314. Specifically, in this embodiment, the limiting part 314 is square, and the corners of the limiting part 314 have auxiliary holes 230.

[0064] In this embodiment, the connecting portion 312 can move along a first direction within the mounting through hole 210, allowing the limiting portion 314 to switch between an abutting state and a non-abutting state. In the abutting state, the limiting portion 314 abuts against the mounting base 200; in the non-abutting state, the limiting portion 314 is separated from the mounting base 200. This facilitates both limiting the limiting portion 314 to be positioned on the mounting base 200 and releasing the limiting portion 314 from the mounting base 200.

[0065] In this embodiment, the adhesive bonding assembly 300 further includes a lifting handle 330. The lifting handle 330 is located on the end of the limiting portion 314 away from the connecting portion 312 and protrudes from the mounting through hole 210. Thus, the adhesive bonding assembly 300 can be controlled to move in the first direction by gripping the lifting handle 330, which is very convenient for operation. It is understood that in other embodiments, the lifting handle 330 may be omitted, in which case the end of the limiting portion 314 away from the connecting portion 312 can be exposed, and the exposed end can be used for gripping.

[0066] In this embodiment, the pressure-bonding structure 10 further includes a limiting component 400. The limiting component 400 includes a first limiting member 410 and a second limiting member 420. The first limiting member 410 is telescopic. One of the first limiting member 410 and the second limiting member 420 is disposed on the inner wall of the mounting through hole 210, and the other is disposed on the connecting portion 312. In the abutting state, the first limiting member 410 and the second limiting member 420 are engaged, that is, when the limiting portion 314 abuts against the mounting base 200, the first limiting member 410 and the second limiting member 420 are engaged, providing double fixation, which makes it easier for the mounting member 310 to be stably fixed on the mounting base 200. In the non-contact state, the first limiting member 410 and the second limiting member 420 separate, that is, when the limiting part 314 separates from the mounting base 200, the first limiting member 410 and the second limiting member 420 separate, thus unlocking the mounting part 310 and facilitating its removal from the mounting base 200.

[0067] In the above-described pressure-adhesive structure 14a, when assembling the pressure-adhesive assembly 300 on the mounting base 200, the relative position of the mounting member 310 and the mounting base 200 can be adjusted in the first direction so that the first limiting member 410 and the second limiting member 420 are distributed at different heights in the first direction. Then, the connecting part 312 is pushed into the mounting through hole 210 in the second direction through the opening 220 (at this time, the first limiting member 410 is compressed). Next, the relative position of the mounting member 310 and the mounting base 200 is adjusted in the first direction so that the limiting part 314 abuts against the mounting base 200, and the first limiting member 410 and the second limiting member 420 are at the same height and engaged in the first direction (at this time, the first limiting member 410 is at its original length), thus completing the assembly of the pressure-adhesive assembly 300 and the mounting base 200. When it is necessary to replace the deformable part 320, the mounting part 310 can be controlled to move in the first direction within the mounting through hole 210, so that the limiting part 314 is separated from the mounting base 200, and the first limiting part 410 and the second limiting part 420 are distributed at different heights in the first direction (at this time, the first limiting part 410 is compressed). Then, the connecting part 312 is pushed out from the mounting through hole 210 in the second direction through the opening 220 (at this time, the first limiting part 410 is at its original length), thus completing the disassembly of the adhesive assembly 300 and the mounting base 200.

[0068] In this embodiment, the first limiting member 410 is disposed on the inner wall of the mounting through hole 210, and the second limiting member 420 is disposed on the connecting portion 312. This facilitates the assembly of the first limiting member 410. It can be understood that in other embodiments, the first limiting member 410 may also be disposed on the connecting portion 312, and the second limiting member 420 may be disposed on the inner wall of the mounting through hole 210.

[0069] In this embodiment, the first limiting member 410 is a ball-head plunger, and the second limiting member 420 is a slot. This facilitates switching between an engaged state and an unengaged state between the first limiting member 410 and the second limiting member 420 when the connecting part 312 moves along the first direction within the mounting through hole 210. It is understood that in other embodiments, the first limiting member 410 may also be other telescopic members, which have a spherical surface that facilitates sliding into and out of the second limiting member 420.

[0070] In this embodiment, the connecting portion 312 has limiting components 400 on both sides parallel to the first direction, that is, the connecting portion 312 has limiting components 400 on both sides in the third direction. This makes it easier for the connecting portion 312 to be stably fixed on the mounting base 200. It can be understood that in other embodiments, the connecting portion 312 may have two limiting components 400 on the side in the third direction; or, the connecting portion 312 may have two limiting components 400 on the side in the second direction.

[0071] In this embodiment, the tape stabilizing mechanism 14 further includes a pressure-adhesion driving structure 14c and / or a mating driving structure. The pressure-adhesion driving structure 14c is connected to the pressure-adhesion structure 14a (mounting base 200) and is used to drive the pressure-adhesion structure 14a to move toward or away from the mating structure 14b, thereby adjusting the distance between the pressure-adhesion structure 14a and the mating structure 14b. The mating driving structure is connected to the mating structure 14b and is used to drive the mating structure 14b to move toward or away from the mating structure 14b, thereby adjusting the distance between the pressure-adhesion structure 14a and the mating structure 14b.

[0072] In this embodiment, the structure of the mating structure 14b is largely the same as that of the pressure-bonding structure 14a. The difference lies in that the contact area between the deformable element 320 of the pressure-bonding structure 14a and the tape 10a is larger than that between the mating structure 14b and the tape 10a. Therefore, in practical applications, the mating structure 14b contacts the adhesive surface of the tape 10a, while the deformable element 320 of the pressure-bonding structure 14a contacts the non-adhesive surface of the tape 10a. This facilitates the separation of the mating structure 14b from the tape 10a. It is understood that in other embodiments, the structure of the mating structure 14b can be completely identical to that of the pressure-bonding structure 14a.

[0073] In this embodiment, as Figure 5 and Figure 6As shown, the tape cutting mechanism 16 includes a cutting blade structure 16a and a cutting blade drive structure 16b. The cutting blade drive structure 16b is connected to the cutting blade structure 16a and is used to drive the cutting blade structure 16a to cut the tape 10a. In this embodiment, the cutting blade drive structure 16b can drive the cutting blade structure 16a to move along the width direction of the tape 10a, thereby cutting the tape 10a from one side of the width direction of the tape 10a toward the other side of the width direction of the tape 10a. It can be understood that in other embodiments, when the length of the blade 620 of the cutting blade structure 16a is greater than the width of the tape 10a, the cutting blade drive structure 16b can also drive the cutting blade structure 16a to move toward the tape 10a to cut the tape 10a.

[0074] In this embodiment, the cutter structure 16a includes a mounting base 500, a cutter assembly 600, and a hand-tightening assembly 700. The cutter assembly 600 includes a detachable arm 610 and a cutter 620 disposed on the detachable arm 610. The end of the detachable arm 610 away from the cutter 620 is detachably connected to the mounting base 500 via the hand-tightening assembly 700. The mounting base 500 and the cutter assembly 600 can be detached via the hand-tightening assembly 700, making it very convenient to disassemble and assemble the cutter assembly (consumable part) 600.

[0075] In this embodiment, the mounting base 500 has a slot 510. The end of the detachable arm 610 furthest from the cutter 620 is inserted into the slot 510. The hand-tightening assembly 700 includes a hand-tightening bolt 710. The hand-tightening bolt 710 passes through one side wall of the slot 510 and the detachable arm 610 and is threaded to the other side wall of the slot 510. This facilitates the assembly and disassembly of the mounting base 500 and the cutter assembly 600.

[0076] In this embodiment, the length of the cutter 620 extending beyond the detachable arm 610 along its length is adjustable. This makes it easier for the cutter 620 to cut the tape 10a. Specifically, in this embodiment, the cutter 620 has an elongated groove 622. The elongated groove 622 extends along the length of the detachable arm 610. The mounting base 500 (groove bottom 6122) has a threaded hole. The cutter 620 is threadedly connected to the threaded hole via an adjusting screw 800 passing through the elongated groove 622. This makes it very easy to achieve adjustable length of the cutter 620 extending beyond the detachable arm 610 along its length.

[0077] In this embodiment, the detachable arm 610 has a receiving groove 612 at the end away from the mounting base 500. The receiving groove 612 has a groove bottom 6122 for the cutter 620 to lie flat and an inner peripheral wall 6124 with a notch. The notch is for the cutter 620 to be exposed. The inner peripheral wall 6124 is for the back of the cutter 620 to abut against. The cutter 620 is fixed flat to the groove bottom 6122 with at least a portion of the cutter 620 exposed from the notch and at least a portion of the back of the cutter 620 abutting against the inner peripheral wall 6124. Thus, during the cutting of the tape 10a, the cutter 620 can abut against the inner peripheral wall 6124, thereby making the cutting of the cutter 620 more stable.

[0078] In other embodiments, such as Figure 7 As shown, the inner peripheral wall 6124 has adjacent first abutment surfaces 6124a and second abutment surfaces 6124b. The back of the cutter 620 has adjacent first and second sides. The first and second sides abut against the first abutment surfaces 6124a and 6124b, respectively. An elongated protrusion 6126 is provided on the groove bottom 6122. The elongated protrusion 6126 engages with the elongated groove 622. This further stabilizes the cutting action of the cutter 620.
