Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to an adhesive applicator. Background Technology

[0002] Adhesive application is a common process in battery production. It involves applying adhesive tape to material strips (such as electrodes and separators) to protect them. In existing technology, the adhesive application device uses a suction cup to pick up the tape and brings it into contact with the material strip as it passes by, thus attaching the tape to the correct position on the material strip.

[0003] However, some tapes are not adhesive. To ensure reliable adhesion between the tape and the substrate, the suction cup needs to increase pressure and maintain that pressure. Using conventional servo pressurization to maintain pressure on the tape requires gradually increasing the pressure to the set level, which is time-consuming and affects application efficiency.

The adhesive suction cup is configured to absorb the adhesive tape. The tape is disposed between the adhesive suction cup and the support structure. The drive assembly can drive the adhesive suction cup to move via the elastic element, so that the adhesive suction cup can press the adhesive tape and the tape against the support structure and compress the elastic element.

[0009] As an optional solution for the above-mentioned adhesive application device, the adhesive application suction cup includes a suction cup body and multiple adjusting components. The suction cup body has multiple adsorption channels, and the sidewall of each adsorption channel has multiple adsorption holes that extend to the surface of the suction cup body.

[0010] As an optional solution for the above-mentioned adhesive application device, each of the multiple adsorption channels is connected to a corresponding negative pressure channel, and the negative pressure channel extends through the surface of the suction cup body to connect to the negative pressure component. One end of the adsorption channel extends through the surface of the suction cup body to form an adjustment port, and the adjustment component passes through the adjustment port to connect or close the connection position between the adsorption channel and the negative pressure channel.

[0011] As an optional embodiment of the above-mentioned adhesive applicator, the adhesive applicator further includes a pressure sensor, which is disposed on the adhesive applicator mechanism or the support structure, and is configured to detect the pressure between the adhesive applicator suction cup and the support structure.

"Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] This embodiment provides an adhesive applicator for attaching adhesive tape to a strip of material. The strip can be a battery electrode (positive or negative electrode), or it can be a battery separator; any sheet structure requiring adhesive tape can be used. The tape is used to cover burrs generated after cutting the electrode, preventing the burrs from piercing the separator.

[0036] To improve efficiency, the conveyor belt moves along the transport direction of the production line. For example... Figure 1 and Figure 2 As shown, the tape-applying device includes a tape-applying mechanism 2 and a support structure for applying tape to the material strip. The tape-applying mechanism 2 includes a fixed base 21 and a tape-applying suction cup 22. Both the fixed base 21 and the support structure are mounted on the frame 1. The tape-applying suction cup 22 is used to pick up the tape to be applied, and the material strip passes between the tape-applying suction cup 22 and the support structure. When the position of the material strip where the tape needs to be applied moves between the tape-applying suction cup 22 and the support structure, the tape-applying suction cup 22 moves towards the support structure, pressing the tape against the material strip and pressing the tape and the material strip together against the support structure, so that the tape is applied to the material strip.

[0037] With advancements in manufacturing processes, some adhesive tapes have lost their adhesive properties. To ensure reliable connections between the tape and the material, it's necessary to increase the pressure between them and maintain that pressure for a specified period. However, the commonly used servo pressurization mode requires a slow increase in pressure between the adhesive suction cup 22 and the support structure. This necessitates the slow movement of the adhesive suction cup 22, and the pressure is maintained by adjusting the gap between it and the support structure. Since even minute displacements can affect the pressure, a pressure gauge is required for real-time monitoring to ensure appropriate pressure levels.

[0038] like Figure 2 As shown, in order to improve the adhesive application efficiency, the adhesive application device provided in this embodiment further includes an elastic element 23 and a driving component 24. The driving component 24 can drive the adhesive application suction cup 22 to move through the elastic element 23, so that the adhesive application suction cup 22 can press the adhesive tape and material strip against the support structure and compress the elastic element 23.

[0039] In this adhesive applicator, the drive component 24 of the adhesive applicator mechanism 2 can drive the adhesive applicator suction cup 22 to approach the support structure via the elastic element 23. This presses the adhesive tape adsorbed by the suction cup 22 and the material strip between the suction cup 22 and the support structure against the support structure, while simultaneously providing a certain pressure to maintain pressure and ensure the reliability of the connection between the adhesive tape and the material strip. The pressure provided by the adhesive applicator suction cup 22 is obtained by compressing the elastic element 23. Therefore, the drive component 24 can accurately set the displacement amount through the parameters of the elastic element 23. This ensures that each time the drive component 24 only needs to move this displacement amount quickly, the elastic element 23 can quickly and accurately adjust the pressure maintained by the adhesive applicator suction cup 22 on the adhesive tape and the material strip. Compared to the servo pressurization mode where even small displacements affect the pressure, the compression amount of the elastic element 23 in this embodiment is larger. As long as the displacement difference is not large each time the tape is pressed, the pressure can remain within a suitable range. This allows the drive component 24 to quickly change the displacement amount, improving the adhesive applicator efficiency.

[0040] like Figure 3As shown, the adhesive applicator also includes a pressure sensor 25, which is disposed on the adhesive applicator 2 or the support structure. The pressure sensor 25 is configured to detect the pressure between the adhesive applicator suction cup 22 and the support structure. By setting the pressure sensor 25, the pressure of each adhesive application and the pressure fluctuation during the pressure holding process can be monitored in real time, which can ensure the reliability of adhesive application and check the stability of the adhesive applicator, ensuring normal operation of the equipment.

[0041] In some embodiments, the pressure sensor 25 may be disposed on the side of the support structure away from the adhesive suction cup 22, and the pressure sensor 25 may also be disposed on the side of the adhesive suction cup 22 away from the support structure, so as to calculate the pressure between the adhesive suction cup 22 and the tape by means of the pressure of the support structure on the pressure sensor 25.

[0042] In this embodiment, the drive assembly 24 includes a drive screw 241 and a pressure plate 242. The pressure plate 242 is connected to a nut 243. The drive screw 241 is rotatably mounted on the fixed base 21 and is threadedly connected to the nut 243. An adhesive suction cup 22 is mounted on the pressure plate 242, and an elastic element 23 is disposed between the adhesive suction cup 22 and the pressure plate 242. When the drive screw 241 rotates, the pressure plate 242 will move linearly along the axial direction of the drive screw 241. Therefore, the drive screw 241 can drive the pressure plate 242 to move closer to or away from the support structure, thereby pressing the tape and the material belt, or separating the tape and the material belt so that the material belt can continue to move.

[0043] Preferably, the drive assembly 24 further includes a drive motor 244, a synchronous belt 245, and synchronous pulleys 246. The drive screw 241 and the shaft of the drive motor 244 are both connected to the synchronous pulleys 246, and the synchronous belt 245 is tensioned by the two synchronous pulleys 246 to ensure synchronous rotation of the two pulleys 246. The drive screw 241 and nut 243 also serve to reduce speed, so that when the drive motor 244 rotates at its normal speed, the pressure plate 242 moves at a slower speed, ensuring smooth movement of the pressure plate 242 and improving the accuracy of adjusting its position.

[0044] In this embodiment, the drive motor 244 is a servo motor. The servo motor can precisely control the rotation angle, achieve high-precision control, and respond quickly and run smoothly, thereby improving the control accuracy of the adhesive pressure.

[0045] Preferably, the drive motor 244 and the synchronous pulley 246 are connected by a reducer 247. The reducer 247 can convert the high speed of the drive motor 244 into the low speed of the synchronous pulley 246, thereby making the synchronous pulley 246 rotate more smoothly and improving accuracy.

[0046] like Figure 2 and Figure 3As shown, the adhesive suction cup 22 is equipped with a guide post 26, and the pressure plate 242 is equipped with a bushing 27. The guide post 26 passes through the bushing 27 and slides in cooperation with the bushing 27. When the adhesive suction cup 22 presses the adhesive tape and material strip against the support structure, the relative movement between the adhesive suction cup 22 and the pressure plate 242 is guided by the guide post 26 and the bushing 27, ensuring the stability of the adhesive suction cup 22.

[0047] It is worth noting that manually applying the tape to the adhesive suction cup 22 is inefficient and carries certain risks. For example... Figure 1 and Figure 4 As shown, to improve production efficiency, the adhesive applicator 2 further includes an adhesive supply component 281 and an adhesive pulling component 282. The adhesive supply component 281 includes a glue tray rotatably mounted on the frame 1, with adhesive tape wound around it, the tape having a free end. The adhesive pulling component 282 can clamp the free end of the tape and move it relative to the adhesive suction cup 22, causing the pulled-out tape to be adsorbed onto the adhesive suction cup 22. When it is necessary to use the adhesive suction cup 22 to adsorb the tape, the adhesive pulling component 282 can be used to pull the free end of the tape, causing the glue tray to rotate, and the pulled-out tape can be adsorbed by the adhesive suction cup 22, resulting in high efficiency.

[0048] Specifically, the tape pulling assembly 282 includes a clamping cylinder 2821 and two grippers 2822. The clamping cylinder 2821 can drive the two grippers 2822 to move closer or further apart. When the two grippers 2822 move closer to each other and simultaneously abut against both sides of the free end of the tape, the free end is clamped, and the tape can be pulled out.

[0049] Preferably, the adhesive applicator 2 further includes a cutting component 283, which includes a cutting element configured to cut the adhesive tape. After the adhesive tape is pulled out by the adhesive pulling component 282 and covers the adhesive applicator suction cup 22, the cutting element can cut the tape, and then the adhesive applicator suction cup 22 approaches the support structure, and the tape can be attached to the material strip.

[0050] In this embodiment, the adhesive application mechanism 2 further includes a smoothing roller 284, which is movable relative to the adhesive application suction cup 22 to press the adhesive tape onto the surface of the adhesive application suction cup 22. The smoothing roller 284 can smooth the adhesive tape adsorbed on the surface of the adhesive application suction cup 22, avoiding tape wrinkling or local vacuum breakage, thus optimizing the adhesive application effect and improving the yield of the electrode sheet.

[0051] Preferably, the adhesive applicator 2 further includes a fixed plate, and both the adhesive pulling component 282 and the smoothing roller 284 are disposed on the fixed plate, with the smoothing roller 284 located on the side of the adhesive pulling component 282 closer to the adhesive supply component 281. This structure allows the smoothing roller 284 to press the adhesive tape near its free end against the adhesive applicator suction cup 22, and the subsequently pulled-out adhesive tape can be smoothly and adsorbed onto the surface of the adhesive applicator suction cup 22.

[0052] In some embodiments, the tape-pulling assembly 282 and the smoothing roller 284 can move independently. After the tape-pulling assembly 282 pulls the tape out to a sufficient length, the smoothing roller 284 moves to smooth the tape.

[0053] In some embodiments, the support structure may be a support platform, and the adhesive suction cup 22 presses the adhesive tape and material strip against the support platform.

[0054] like Figures 1-3 As shown, the support structure can also be another adhesive applicator 2. The adhesive applicator suction cups 22 of the two adhesive applicator 2 are arranged facing each other, and the material strip is located between the two adhesive applicator suction cups 22. At least one of the two adhesive applicator 2 is provided with an elastic element 23.

[0055] In other words, both adhesive suction cups 22 are holding adhesive tape. When the material strip moves to the position where the tape needs to be applied, the two adhesive suction cups 22 move closer together and press against each other, allowing the two tapes to be applied to opposite sides of the material strip. This is equivalent to applying two tapes at once, improving efficiency. At least one adhesive application mechanism 2 is equipped with an elastic element 23 to ensure that the two adhesive suction cups 22 quickly reach and maintain appropriate pressure.

[0056] In some embodiments, both adhesive application mechanisms 2 may be provided with elastic elements 23, or one of the two adhesive application mechanisms 2 may be provided with an elastic element 23 and the other with a pressure sensor 25.

[0057] Preferably, when one of the two adhesive applicator mechanisms 2 is equipped with an elastic element 23 and the other is equipped with a pressure sensor 25, the other structures of the two adhesive applicator mechanisms 2 are completely the same. The difference is that the elastic element 23 is provided between the pressure plate 242 and the adhesive suction cup 22 of one adhesive applicator mechanism 2, and the pressure sensor 25 is provided between the pressure plate 242 and the adhesive suction cup 22 of the other adhesive applicator mechanism 2.

[0058] In addition, since different tapes require different sizes of adhesive tape, the adhesive suction cup 22 of the adhesive applicator 2 can adjust the size of the adsorption range in order to improve applicability.

[0059] Specifically, such as Figure 5As shown, the adhesive suction cup 22 includes a suction cup body 221 and multiple adjusting components 222. The suction cup body 221 has multiple adsorption channels 2211. Each adsorption channel 2211 has multiple adsorption holes 2212 extending to the surface of the suction cup body 221 on its sidewall. Each adjusting component 222 corresponds to one adsorption channel 2211 and is used to open or close the adsorption channels 2211 to adjust the adsorption range of the adhesive suction cup 22. The operator can control the adjusting components 222 by adjusting the size of the adhesive tape, so that the adsorption range formed by the open adsorption channels 2211 of the adhesive suction cup 22 corresponds to the size of the adhesive tape, ensuring complete adsorption of the tape without affecting the adsorption effect due to an excessively large adsorption range.

[0060] Furthermore, each of the multiple adsorption channels 2211 is connected to a corresponding negative pressure channel 2213, and the negative pressure channel 2213 extends to the surface of the suction cup body 221 to connect to the negative pressure component. One end of the adsorption channel 2211 extends to the surface of the suction cup body 221 to form an adjustment port, and the adjustment member 222 passes through the adjustment port to connect or close the connection position between the adsorption channel 2211 and the negative pressure channel 2213.

[0061] Understandably, when the operator controls the adjustment component 222 to move one end inside the adhesive suction cup 22 to the position where the connection between the adsorption channel 2211 and the negative pressure channel 2213 is blocked, the adsorption channel 2211 and the negative pressure channel 2213 are disconnected, the adsorption channel 2211 cannot generate negative pressure, and the adsorption hole 2212 corresponding to the adsorption channel 2211 cannot adsorb the adhesive tape.

[0062] In this embodiment, the adsorption holes 2212 of the adsorption channel 2211 are located at both ends of the connection between the adsorption channel 2211 and the negative pressure channel 2213. That is, as the adjusting member 222 gradually enters the adhesive suction cup 22 from the adjusting port, the adjusting member 222 will block the adsorption holes 2212 of the adsorption channel 2211 in sequence, which can adjust the adsorption range of each adsorption channel 2211. In addition, the adjusting member 222 can directly disconnect the connection between the adsorption channel 2211 and the negative pressure channel 2213. Therefore, the operator can adjust the size of the adsorption range from two mutually perpendicular directions.

[0063] 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.
