Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a high-flatness adhesive application device. Background Technology

[0002] Adhesive bonding is a common process in battery production. It involves applying adhesive tape to material strips (such as electrodes or separators) to protect them. In existing technology, adhesive bonding devices include a support roller and a rotating adhesive bonding roller. The adhesive bonding roller has suction holes that hold a section of adhesive tape in place. The support roller supports the moving material strip. As the adhesive bonding roller rotates, it is pressed against the support roller, and when the tape reaches contact with the material strip, it is bonded to it.

[0003] However, because the surface of the adhesive roller is curved, it is easy for the tape to wrinkle or locally break the vacuum when it is pulled and attached to the surface of the adhesive roller, resulting in an uneven tape surface, which affects the adhesive application effect and the yield of the electrode sheets. Utility Model Content

[0019] As an optional solution for the above-mentioned high flatness adhesive applicator, the adhesive supply mechanism further includes a steering roller and a third adhesive pressing component.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment provides a high-flatness adhesive application device (hereinafter referred to as the adhesive application device) for applying adhesive tape to a strip. The strip can be a battery electrode (positive or negative electrode), or it can be a battery separator; any sheet structure that requires adhesive tape application is acceptable. The adhesive tape is used to cover burrs generated after cutting the electrode, preventing the burrs from piercing the separator.

[0039] like Figure 1 As shown, the adhesive applicator includes an adhesive supply mechanism 2, which includes an adhesive tray 21 and multiple rotating rollers 22. The adhesive tray 21 is wound with adhesive tape, which has a free end. The adhesive supply mechanism 2 is used to supply adhesive tape to the adhesive applicator. The multiple rotating rollers 22 are used to roll and abut against the adhesive tape to tension it. When the adhesive tape is pulled through the free end, the adhesive tray 21 can be driven to rotate, thereby pulling out the adhesive tape.

[0040] like Figures 1-3 As shown, in this embodiment, the adhesive applicator further includes an adhesive applicator 1, an adhesive pulling mechanism 3, and a cutting mechanism 4. The adhesive applicator 1 includes an adhesive applicator roller 12 and a support roller 11. The tape is disposed on the support roller 11 and moves along the transmission direction. The support roller 11 is used to support the tape. The adhesive applicator roller 12 has adsorption holes 123 on its surface. The adhesive pulling mechanism 3 includes a clamping component 31. The clamping component 31 can clamp the free end and move along the axial direction of the adhesive applicator roller 12 to pull out the tape. The adhesive applicator roller 12 can adsorb and fix the tape pulled out by the adhesive pulling mechanism 3. The cutting mechanism 4 includes a cutting element 41, which is configured to cut the tape.

[0041] In this adhesive applicator, the support roller 11 supports the moving tape. The clamping component 31 of the tape pulling mechanism 3 can clamp the free end of the tape and move along the axial direction of the tape applicator roller 12 to pull out the tape and cover it on the tape applicator roller 12. The tape is then cut by the cutting component 41. The tape applicator roller 12 then rotates. When the tape rotates with the tape applicator roller 12 to abut against the tape, the tape can be attached to the tape. The support roller 11 can ensure that there is sufficient pressure between the tape and the tape to ensure the reliability of tape attachment.

[0042] In this embodiment, the adhesive applicator further includes a substrate 5. The adhesive supply mechanism 2, the adhesive pulling mechanism 3, and the cutting mechanism 4 are all disposed on the substrate 5. The adhesive applicator 1 is disposed below the substrate 5. The substrate 5 can integrate multiple mechanisms of the adhesive applicator, making the structure more compact, reducing the space occupied, and facilitating arrangement. Among the multiple rollers 22 of the adhesive supply mechanism 2, at least one is movable and disposed on the substrate 5 to adjust the tension of the adhesive tape.

[0043] like Figure 1 As shown, the adhesive roller 12 includes a main shaft 122 and an adhesive protrusion 121. The adhesive protrusion 121 is disposed on the side wall of the main shaft 122. An adsorption hole 123 is provided on the adhesive protrusion 121. The support roller 11 is spaced apart from the main shaft 122, and the gap between the support roller 11 and the main shaft 122 is less than or equal to the height of the adhesive protrusion 121. This ensures that when the adhesive roller 12 rotates, the two will only come into contact when the adhesive protrusion 121 faces the support roller 11, so as to stick the tape onto the material belt.

[0044] In order for the adhesive roller 12 and the support roller 11 to complete the adhesive application operation on the material strip when rotating, the surface of the adhesive protrusion 121 is arc-shaped. When the clamping component 31 pulls the tape and attaches it to the surface of the adhesive roller 12, it is easy to wrinkle or locally break the vacuum, resulting in an uneven tape surface, which affects the adhesive application effect and the yield of the electrode sheet.

[0045] like Figure 2 As shown, to solve the above problems, the smoothing roller 32 has a first arc-shaped groove 321 circumferentially. The smoothing roller 32 can move along the axial direction of the adhesive roller 12. The first arc-shaped groove 321 is adapted to the surface of the adhesive roller 12 to press the adhesive tape onto the surface of the adhesive roller 12. The smoothing roller 32 can lay the adhesive tape on the adhesive roller 12 and be adsorbed and fixed by the adsorption hole 123. Since the smoothing roller 32 has a first arc-shaped groove 321 adapted to the surface of the adhesive roller 12, the smoothing roller 32 can smooth the adhesive tape adsorbed on the surface of the adhesive roller 12, avoiding the tape from wrinkling or local vacuum breaking, optimizing the adhesive application effect and improving the yield of the electrode sheet.

[0046] The first arc-shaped groove 321 being adapted to the surface of the adhesive roller 12 means that, in the axial cross-sectional view of the smoothing roller 32, the radius of curvature of the first arc-shaped groove 321 is the same as the radius of curvature of the arc-shaped surface of the adhesive roller 12, allowing the adhesive roller 12 to conform to the first arc-shaped groove 321. Preferably, the first arc-shaped groove 321 is adapted to the surface of the adhesive protrusion 121.

[0047] In this embodiment, the adhesive pulling mechanism 3 further includes a first fixing plate 33. The clamping component 31 and the smoothing roller 32 are both disposed on the first fixing plate 33, and the smoothing roller 32 is located on the side of the clamping component 31 closer to the adhesive supply mechanism 2. This structure allows the smoothing roller 32 to press the adhesive tape near its free end against the adhesive-applying protrusion 121, thereby giving the adhesive tape a certain curvature. The adhesive tape pulled out later can then be smoothly and evenly adsorbed onto the surface of the adhesive-applying protrusion 121.

[0048] In some embodiments, the clamping assembly 31 and the smoothing roller 32 can move independently. After the clamping assembly 31 pulls the tape out to a sufficient length, the smoothing roller 32 moves to smooth the tape.

[0049] Preferably, the smoothing roller 32 is vertically mounted on the first fixed plate 33 to adjust the distance between the smoothing roller 32 and the adhesive protrusion 121, so that the smoothing roller 32 can rise and avoid the clamping component 31, making it easier for the clamping component 31 to clamp the free end of the tape.

[0050] In this embodiment, the clamping assembly 31 includes a clamping cylinder 311 and two grippers 312. The clamping cylinder 311 can drive the two grippers 312 to move closer or further apart from each other; the lifting and lowering of the smoothing roller 32 is driven by a lifting cylinder.

[0051] It is worth noting that after the cutting element 41 cuts the tape, the remaining tape in the adhesive backing mechanism forms a new free end. For example... Figure 1 and Figure 4 As shown, in order to ensure that the adhesive tape of the backing mechanism does not loosen, the adhesive supply mechanism 2 also includes an adhesive preparation suction cup 23. The adhesive preparation suction cup 23 is disposed at one end of the adhesive roller 12. The adhesive preparation suction cup 23 is configured to adsorb and fix the adhesive tape, and the free end is located outside the range of the adhesive preparation suction cup 23.

[0052] The adhesive suction cup 23 can adsorb and fix the tape, and throw the free end of the tape outside the adhesive suction cup 23 so that the clamping component 31 can clamp the free end. Moreover, when the clamping component 31 needs to pull the free end, the adhesive suction cup 23 stops adsorbing the tape so that the tape can be pulled.

[0053] like Figure 3 As shown, the cutting mechanism 4 also includes a first adhesive pressing component 42, which is vertically and flexibly positioned above the adhesive preparation suction cup 23. The first adhesive pressing component 42 is configured to press the tape against the adhesive preparation suction cup 23. The adhesive preparation suction cup 23 provides relatively weak fixation for the tape, while the first adhesive pressing component 42 ensures the stability of the tape when it is cut, preventing the cutting component 41 from pulling on the tape. This not only prevents the tape from being stretched and affecting the continuity of the operation, but also makes the tape easier to cut, thus improving efficiency.

[0054] Preferably, the cutting mechanism 4 further includes a second fixed plate 44 and a first elastic member 43. The cutting member 41 is disposed on the second fixed plate 44, and the first pressing member 42 is movably disposed on the second fixed plate 44. The two ends of the first elastic member 43 abut against the second fixed plate 44 and the first pressing member 42, respectively, and the first elastic member 43 can provide downward pressure to the first pressing member 42. When the first pressing member 42 presses the tape against the adhesive suction cup 23, as the second fixed plate 44 continues to move, the pressure of the first pressing member 42 on the tape gradually increases. On the one hand, this can effectively regulate the pressure of the first pressing member 42 on the tape, and on the other hand, it can make the pressure of the first pressing member 42 on the tape increase slowly, avoiding damage to the tape.

[0055] It is worth noting that when cutting the tape, it is also necessary to prevent the tape on the adhesive protrusion 121 from being pulled off the adhesive protrusion 121 by the cutting member 41. To achieve the above objective, the cutting mechanism 4 also includes a second pressing member 45, which is configured to press the tape against the surface of the adhesive protrusion 121.

[0056] Preferably, in order to ensure that the second pressing component 45 fits against the adhesive protrusion 121, the pressing surface of the second pressing component 45 is provided with a second arc-shaped groove 451, which is adapted to the surface of the adhesive roller 12. The concept of adaptation has been described in detail above and will not be repeated here.

[0057] In this embodiment, the cutting mechanism 4 further includes a second elastic member 46. The second pressing member 45 is movably disposed on the second fixed plate 44, and the second elastic member 46 is disposed between the second pressing member 45 and the second fixed plate 44. The second elastic member 46 can provide downward pressure to the second pressing member 45. When the second pressing member 45 presses the tape against the adhesive protrusion 121, as the second fixed plate 44 continues to move, the pressure of the second pressing member 45 on the tape gradually increases. On the one hand, this can effectively regulate the pressure of the second pressing member 45 on the tape, and on the other hand, it can make the pressure of the second pressing member 45 on the tape increase slowly, avoiding damage to the tape.

[0058] like Figure 3 As shown, it is worth noting that in the initial state, the bottom end of the cutting part 41 is higher than the bottom ends of the first pressing part 42 and the second pressing part 45. As the second fixing plate 44 moves downward, the first pressing part 42 stops moving downward after abutting against the adhesive suction cup 23, and the second pressing part 45 stops moving downward after abutting against the adhesive protrusion 121, while the cutting part 41 continues to move downward, thereby cutting the tape between the first pressing part 42 and the second pressing part 45.

[0059] Preferably, the cutting mechanism 4 further includes a cutting drive 47, which is used to drive the second fixed plate 44 to rise and fall, thereby driving the cutting component 41, the first pressing component 42 and the second pressing component 45 to move downward, so as to cut the tape while pressing the tape.

[0060] In this embodiment, the glue supply mechanism 2 further includes a third fixing plate 24, which is vertically movable on the substrate 5. The glue preparation suction cup 23 is disposed on the third fixing plate 24. Therefore, the glue preparation suction cup 23 can be raised and lowered to adjust the relative height of the glue preparation suction cup 23 relative to the glue application roller 12. This can both match the height of the clamping component 31 of the glue pulling mechanism 3, making it easy for the clamping component 31 to clamp the free end of the tape, and also make the glue preparation suction cup 23 slightly higher than the glue application protrusion 121, so that while pulling the tape, the tape will not be too far away from the glue application protrusion 121, ensuring that the glue application protrusion 121 can adsorb the tape.

[0061] Preferably, the adhesive supply mechanism 2 further includes a guide roller 25 and a third pressing component 26. The guide roller 25 is located upstream of the adhesive suction cup 23. After the tape is tensioned by the guide roller 25, it passes through the adhesive suction cup 23. The third pressing component 26 is configured to press the tape against the guide roller 25. The function of the guide roller 25 is to adjust the direction of the tape, so that the free end of the tape and the end near the free end extend horizontally, which facilitates the adhesive suction cup 23 to adsorb and fix the tape, and also facilitates the clamping component 31 to clamp the tape. The third pressing component 26 can press the tape against the guide roller 25, so that the tape is stably fixed, ensuring that the tape will not loosen or retract, and ensuring that the tape remains taut during shutdown. This reduces adjustment time and improves efficiency when the machine is restarted.

[0062] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
