[0002] Applying adhesive is an important step in the production of electrode sheets, and its purpose is to protect, insulate, or mark the electrode sheets.

[0003] In related technologies, double-sided adhesive application of electrodes is usually done manually or semi-automatically. That is, adhesive is applied to one side of the electrode first, and then the electrode is flipped over to apply adhesive to the other side. This method is not only inefficient, but also prone to electrode displacement during the flipping process, affecting the quality of adhesive application and the electrode itself.

[0004] In addition, because the electrode sheets are prone to misalignment during transport, the tape application device may skew the application position during the application process, resulting in poor application accuracy. Utility Model Content

[0036] The electrode applicator 10 and electrode applicator according to embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Reference Figures 1-3 As shown, the electrode applicator 10 according to an embodiment of the present invention can be used to attach tape 11 to an electrode 2000. The electrode applicator 10 includes: a film roll 1, a release roller 2, and a pressing block 3. The film roll 1 is wound with tape 11, and the tape 11 has an adhesive side and a backing side. The film roll 1 is rotatably sleeved on the release roller 2. In the width direction of the electrode 2000, the release roller 2 is used to adjust the position of the film roll 1 relative to the electrode 2000. In the thickness direction of the electrode 2000, the pressing block 3 is used to press the tape 11 against one side of the backing side so that the adhesive side of the tape 11 is in contact with the electrode 2000.

[0038] Specifically, the electrode applicator 10 can be used in an electrode applicator device. The electrode applicator 10 can attach the tape 11 to the electrode 2000 to automate the applicator process of the electrode 2000 during production, improve production efficiency, and reduce the labor intensity of manufacturing personnel. The tape 11 can protect, insulate, or mark the electrode 2000.

[0039] The electrode applicator 10 includes: a film roll 1, a release roller 2, and a pressing block 3. The film roll 1 is rotatably mounted on the release roller 2. The film roll 1 is wound with an adhesive tape 11. The adhesive tape 11 has an adhesive side and a backing side. The adhesive side is sticky, and the backing side can be made of paper. The adhesive side at the beginning of the tape 11 can be adhered to the electrode 2000. As the electrode 2000 moves forward, the electrode 2000 moves forward synchronously with the beginning of the tape 11, and the film roll 1 rotates on the release roller 2 to release a longer tape 11.

[0040] Meanwhile, in the thickness direction of electrode 2000, i.e. Figure 3 In the vertical direction, the pressing block 3 presses against the tape 11 on one side of the backing material surface of the tape 11 to prevent the tape 11 from sticking to the pressing block 3, and to make the adhesive surface of the tape 11 adhere to the electrode 2000, thereby ensuring that the adhesive surface of the tape 11 is reliably bonded to the electrode 2000, making the tape 11 conform to the electrode 2000, and improving the bonding quality of the tape 11.

[0041] Additionally, in the width direction of electrode 2000, i.e. Figure 2 In the left and right direction, the release roller 2 can adjust the position of the film roll 1 relative to the electrode 2000. When the electrode 2000 is offset, the position of the film roll 1 can be adjusted by the release roller 2 so that the tape 11 corresponds to the preset bonding position of the electrode 2000, and the tape 11 is prevented from wrinkling or sticking crookedly.

[0042] In some embodiments, the release roller 2 is mounted to the fixing plate 7 of the electrode applicator 10 via a threaded structure thereon. The release roller 2 can be rotated to change its axial direction (i.e., Figure 2 The length of the fixing plate 7 is screwed into the left and right direction of the film to adjust the position of the film 1 relative to the electrode 2000.

[0043] In other embodiments, the release roller 2 is provided with a sliding limit plate, which can slide in the left and right direction to push the film roll 1 to adjust its position.

[0044] According to the embodiment of the present invention, when the electrode 2000 is misaligned, the position of the adhesive roll 1 can be adjusted by the release roller 2 to avoid the tape 11 from wrinkling or sticking crookedly. The pressing block 3 can make the adhesive surface of the tape 11 fit with the electrode 2000, so that the tape 11 is flat. The electrode adhesive applicator 10 can realize the automation of the adhesive application process and improve the adhesive application accuracy.

[0045] In some embodiments of this utility model, reference is made to Figure 3 As shown, the electrode applicator 10 also includes a pressure block drive 4, which is connected to the clamping block 3. In the thickness direction of the electrode 2000, the pressure block drive 4 is used to drive the clamping block 3 to move closer to or away from the electrode 2000.

[0046] Specifically, in the thickness direction of electrode 2000, i.e. Figure 3 In the vertical direction, the pressure block drive 4 can drive the pressure block 3 to move closer to or further away from the electrode 2000, so as to adjust the pressure of the pressure block 3 on the electrode 2000 through the tape 11, so as to avoid the pressure being too high or too low and affecting the bonding quality of the tape 11.

[0047] When the pressure of the clamping block 3 on the electrode 2000 through the tape 11 is small, air bubbles are easily formed between the tape 11 and the electrode 2000, and the tape 11 and the electrode 2000 are not in good contact. At this time, the clamping block driving component 4 can drive the clamping block 3 to move closer to the electrode 2000, thereby increasing the pressure of the clamping block 3 on the electrode 2000 through the tape 11, so as to avoid the formation of air bubbles between the tape 11 and the electrode 2000 and the problem of the tape 11 and the electrode 2000 not in good contact.

[0048] When the pressure of the clamping block 3 on the electrode 2000 through the tape 11 is too high, problems such as the tape 11 breaking and the electrode 2000 being damaged are likely to occur. At this time, the clamping block drive 4 can drive the clamping block 3 away from the electrode 2000, thereby reducing the pressure of the clamping block 3 on the electrode 2000 through the tape 11, so as to avoid problems such as the tape 11 breaking and the electrode 2000 being damaged.

[0049] Optionally, the pressing block drive 4 is a pneumatic cylinder or a hydraulic cylinder, and the pressing block drive 4 can drive the pressing block 3 to move closer to or away from the electrode 2000 by extending and retracting in the vertical direction.

[0050] In some embodiments of this utility model, reference is made to Figure 3 As shown, the clamping block 3 is rotatably connected to the clamping block drive 4. The clamping block 3 has a negative pressure adsorption hole, which is used to adsorb the backing surface of the tape 11.

[0051] The clamping block 3 can be connected to a negative pressure generating device, which can draw negative pressure into the negative pressure adsorption hole of the clamping block 3, so that the clamping block 3 adsorbs the backing material of the tape 11 at the negative pressure adsorption hole. The clamping block 3 is rotatably connected to the clamping block driving component 4 so that the clamping block 3 can stick the starting end of the tape 11 to the electrode 2000.

[0052] Specifically, when the electrode applicator 10 is first used, the negative pressure adsorption hole of the clamping block 3 is located on the side of the clamping block 3 away from the electrode 2000. Then, the starting end of the tape 11 is placed in the negative pressure adsorption hole of the clamping block 3, so that the negative pressure adsorption hole adsorbs the backing surface of the starting end of the tape 11. At this time, the adhesive surface of the starting end of the tape 11 is away from the electrode 2000. Then, the clamping block 3 is rotated 180° so that the adhesive surface faces the electrode 2000. The clamping block drive 4 drives the clamping block 3 to approach the electrode 2000, so that the adhesive surface of the starting end of the tape 11 is bonded to the electrode 2000.

[0053] During the above process, the negative pressure adsorption hole can adsorb the backing surface of the tape 11 to ensure that the tape 11 will not detach from the clamping block 3 when the clamping block 3 is raised and lowered. When the clamping block 3 is in use, the clamping block 3 is first rotated so that the negative pressure adsorption hole is away from the electrode 2000 to ensure that the manufacturing personnel have a large operating space to place the starting end of the tape 11 on the negative pressure adsorption hole to avoid interference between the tape 11 and the electrode 2000. Then the clamping block 3 is rotated 180° to flip it over so that the adhesive side of the tape 11 faces the electrode 2000.

[0054] Optionally, the negative pressure adsorption hole on the clamping block 3 can be replaced with a vacuum suction cup to achieve the same adsorption of the backing surface of the tape 11.

[0055] In some embodiments of this utility model, the electrode applicator 10 further includes a rotary motor connected between the clamping block 3 and the clamping block drive member 4. The rotary motor can drive the clamping block 3 to rotate relative to the clamping block drive member 4, so as to realize the automated control of the rotation of the clamping block 3.

[0056] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 As shown, the electrode applicator 10 also includes: a tape tensioner 5, which is disposed between the release roller 2 and the pressing block 3. The tape 11 is wound around the tape tensioner 5. The tape tensioner 5 is used to tension the tape 11. In the width direction of the electrode 2000, the tape tensioner 5 is also used to adjust the position of the tape 11 relative to the electrode 2000.

[0057] Specifically, the tape tensioner 5 can tighten the tape 11 to prevent it from shaking, thereby improving the adhesion accuracy of the tape 11 on the electrode 2000 and preventing wrinkles from forming. In the width direction of the electrode 2000, the tape tensioner 5 is also used to adjust the position of the tape 11 relative to the electrode 2000. When the electrode 2000 shifts, the tape tensioner 5 and the release roller 2 can synchronously adjust the position of the film roll 1 so that the tape 11 corresponds to the preset bonding position of the electrode 2000, preventing the tape 11 from wrinkling or sticking crookedly.

[0058] In some embodiments, the tape tensioning member 5 includes a tensioning wheel, a tensioning shaft, a slider, a base, and a spring. The slider is slidably connected to the base, the tensioning shaft is mounted on the slider, the tensioning wheel is rotatably sleeved on the tensioning shaft, the spring abuts against the base and the slider, and the tape 11 is wound around the tensioning wheel. The elastic force applied by the spring to the slider causes the slider to tension the tape 11 through the tensioning shaft and the tensioning wheel. The tensioning shaft is mounted to the slider through a threaded structure thereon, and the tensioning shaft can be changed in its axial direction (i.e., by screwing it on). Figure 2 The length of the slider is screwed into the left and right direction of the middle, thereby adjusting the position of the tension wheel and the tape 11 relative to the electrode 2000.

[0059] In some embodiments, refer to Figure 3 As shown, the electrode applicator 10 also includes multiple tape guides 6. The tape 11 between the film roll 1 and the clamping block 3 can bypass the tape guides 6. The tape guides 6 can support the tape 11 and change the direction of the tape 11. The tape guides 6 can also adjust the position of the tape 11 relative to the electrode 2000 in the width direction of the electrode 2000.

[0060] The tape guide 6 may include a guide wheel and a guide shaft. The guide wheel is rotatably mounted on the guide shaft. The tape 11 passes around the guide wheel. The guide shaft can be mounted to the fixing plate 7 of the electrode applicator 10 via a threaded structure thereon. The axial direction of the guide shaft can be changed by screwing it on. Figure 2 The length of the fixing plate 7 is screwed into the left and right direction of the plate, thereby adjusting the position of the guide wheel and the tape 11 relative to the electrode 2000.

[0061] Reference Figures 1-3 As shown, the electrode adhesive applicator according to another embodiment of the present invention includes an unwinding mechanism 200, an adhesive applicator 100, and a winding mechanism 300. The unwinding mechanism 200 is used to release the electrode 2000, and the winding mechanism 300 is used to wind up the electrode 2000 released by the unwinding mechanism 200. The adhesive applicator 100 is disposed between the unwinding mechanism 200 and the winding mechanism 300 in the length direction of the electrode 2000.

[0062] The adhesive applicator 100 includes two adhesive applicator components 101. The two adhesive applicator components 101 are arranged opposite to each other in the width direction of the electrode 2000. The adhesive applicator component 101 includes two electrode applicators 10. The electrode applicator 10 is the electrode applicator 10 of the above embodiment. In the thickness direction of the electrode 2000, the two electrode applicators 10 of the adhesive applicator component 101 are arranged opposite to each other on both sides of the electrode 2000.

[0063] In the length direction of electrode 2000, i.e. Figure 3 In the front-back direction, the electrode 2000 is released by the unwinding mechanism 200, and then wound up by the rewinding mechanism 300 after passing through the adhesive application mechanism 100. The unwinding mechanism 200 and the rewinding mechanism 300 can provide power for the movement of the electrode 2000. When the electrode 2000 passes through the adhesive application mechanism 100, multiple strips of adhesive tape 11 can be applied to both sides of the electrode 2000.

[0064] Specifically, the adhesive applicator 100 includes two adhesive applicator components 101 arranged opposite each other in the left-right direction. Each adhesive applicator component 101 includes two electrode adhesive applicators 10 arranged opposite each other in the up-down direction. That is, the adhesive applicator 100 includes four electrode adhesive applicators 10. The four electrode adhesive applicators 10 can respectively apply adhesive tape 11 to the left edge, right edge, left edge, and right edge of the upper surface, lower surface, and lower surface of the electrode 2000. When applying the adhesive tape 11, it is not necessary to flip the electrode 2000 over, so as to improve the application efficiency of the adhesive tape 11, reduce the manufacturing time of the electrode 2000, and adapt to the needs of large-scale mass production.

[0065] According to the electrode adhesive applicator of this utility model embodiment, the electrode 2000 is released by the unwinding mechanism 200, and then wound up by the winding mechanism 300 after passing through the adhesive applicator 100. When the electrode 2000 passes through the adhesive applicator 100, the four electrode adhesive applicators 10 of the adhesive applicator 100 can stick four strips of adhesive tape 11 on both sides of the electrode 2000 to improve the adhesive tape 11 sticking efficiency. At the same time, when the electrode 2000 deviates, the position of the tape roll 1 can be adjusted by the release roller 2 to avoid the tape 11 wrinkling or sticking crookedly. The clamping block 3 can make the adhesive surface of the tape 11 fit with the electrode 2000, so that the tape 11 is flat. The electrode adhesive applicator can realize the automation of the adhesive applicator process and improve the adhesive applicator accuracy.

[0066] Reference Figure 1 As shown, the unwinding mechanism 200 includes an unwinding roller 201 and an unwinding drive 202. The electrode 2000 is wound around the unwinding roller 201. The unwinding drive 202 is connected to the unwinding roller 201 for transmission. The unwinding drive 202 is used to drive the unwinding roller 201 to rotate, thereby realizing the unwinding of the electrode 2000. The unwinding drive 202 can be an electric motor.

[0067] Reference Figure 1 As shown, the winding mechanism 300 includes a winding roller 301 and a winding drive 302. The electrode 2000 is wound around the winding roller 301. The winding drive 302 is connected to the winding roller 301 for transmission. The winding drive 302 is used to drive the winding roller 301 to rotate, thereby realizing the winding of the electrode 2000. The winding drive 302 can be an electric motor.

[0068] In some embodiments of this utility model (not shown in the figures), the electrode adhesive applicator further includes a pre-treatment mechanism. The pre-treatment mechanism is located between the unwinding mechanism 200 and the adhesive applicator 100 along the length of the electrode 2000. The electrode 2000 passes through the pre-treatment mechanism. The pre-treatment mechanism is used to clean and / or flatten the two surfaces of the electrode 2000 in the thickness direction.

[0069] Specifically, the pretreatment mechanism can clean the two surfaces of the electrode 2000 in the thickness direction, that is, clean the upper and lower surfaces of the electrode 2000 where the tape 11 needs to be applied, remove dust, impurities, etc. from the surface of the electrode 2000, so as to ensure the cleanliness of the surface of the electrode 2000 and avoid the dust and impurities on the surface of the electrode 2000 from affecting the bonding strength of the tape 11.

[0070] The pretreatment mechanism may include an upper cleaning roller and a lower cleaning roller. The upper cleaning roller is rotatably disposed on one side of the electrode 2000 in the thickness direction, and the lower cleaning roller is rotatably disposed on the other side of the electrode 2000 in the thickness direction. When the electrode 2000 passes through the pretreatment mechanism, the upper cleaning roller can perform roller brush cleaning on the upper surface of the electrode 2000, and the lower cleaning roller can perform roller brush cleaning on the lower surface of the electrode 2000.

[0071] The pretreatment mechanism can flatten the two surfaces of the electrode 2000 in the thickness direction, that is, flatten the upper and lower surfaces of the electrode 2000 where the tape 11 needs to be applied, so as to eliminate wrinkles on the surface of the electrode 2000 and avoid the wrinkles on the surface of the electrode 2000 from affecting the bonding strength of the tape 11.

[0072] The pretreatment mechanism may include an upper leveling roller and a lower leveling roller. The upper leveling roller is rotatably disposed on one side of the electrode sheet 2000 in the thickness direction, and the lower leveling roller is rotatably disposed on the other side of the electrode sheet 2000 in the thickness direction. When the electrode sheet 2000 passes through the pretreatment mechanism, the upper leveling roller can roll flatten the upper surface of the electrode sheet 2000, and the lower leveling roller can roll flatten the lower surface of the electrode sheet 2000.

[0073] In some embodiments of this utility model, reference is made to Figures 1-4 As shown, the electrode adhesive applicator further includes a pressing mechanism 400. Along the length of the electrode 2000, the pressing mechanism 400 is located between the adhesive applicator 100 and the winding mechanism 300. The pressing mechanism 400 includes an upper pressing roller 401, a lower pressing roller 402, and a pressure adjusting component. The upper pressing roller 401 is rotatably disposed on one side of the electrode 2000 in the thickness direction, and the lower pressing roller 402 is rotatably disposed on the other side of the electrode 2000 in the thickness direction. The pressure adjusting component is connected to the upper pressing roller 401 and the lower pressing roller 402 respectively. In the thickness direction of the electrode 2000, the pressure adjusting component is used to adjust the distance between the upper pressing roller 401 and the lower pressing roller 402.

[0074] Specifically, the pressing mechanism 400 is located between the adhesive application mechanism 100 and the winding mechanism 300. After the electrode 2000 is adhesively applied at the adhesive application mechanism 100, it is then pressed a second time by the pressing mechanism 400. The pressing mechanism 400 can eliminate air bubbles between the tape 11 and the electrode 2000, ensuring the strong adhesion between the tape 11 and the electrode 2000.

[0075] When the electrode 2000 passes through the pressing mechanism 400, the upper pressing roller 401 can perform a roller pressing process on the upper surface of the electrode 2000 to compact the tape 11 on the upper surface of the electrode 2000 towards the electrode 2000, and the lower pressing roller 402 can perform a roller pressing process on the lower surface of the electrode 2000 to compact the tape 11 on the lower surface of the electrode 2000 towards the electrode 2000.

[0076] In the thickness direction of electrode 2000, i.e. Figure 4 In the vertical direction, the pressure adjusting component is used to adjust the distance between the upper pressing roller 401 and the lower pressing roller 402, thereby controlling the pressure of the upper pressing roller 401 and the lower pressing roller 402 on the electrode 2000. When the distance between the upper pressing roller 401 and the lower pressing roller 402 decreases, the pressure of the upper pressing roller 401 and the lower pressing roller 402 on the electrode 2000 increases. When the distance between the upper pressing roller 401 and the lower pressing roller 402 increases, the pressure of the upper pressing roller 401 and the lower pressing roller 402 on the electrode 2000 decreases. The pressure adjusting component can adapt the pressing mechanism 400 to electrode 2000s of different thicknesses by adjusting the distance between the upper pressing roller 401 and the lower pressing roller 402 in the vertical direction.

[0077] In some embodiments, the pressure regulating component may be an electric telescopic rod, one end of which is connected to the upper pressing roller 401 and the other end of which is connected to the lower pressing roller 402. The electric telescopic rod can adjust the distance between the upper pressing roller 401 and the lower pressing roller 402 by extending and retracting.

[0078] In other embodiments, the pressure regulating element can be a tension spring, one end of which is connected to the upper pressing roller 401 and the other end of which is connected to the lower pressing roller 402. The tension spring can apply tension to the upper pressing roller 401 and the lower pressing roller 402 in a direction that brings them closer to each other. When the thickness of the electrode 2000 changes, the tension spring can change the amount of tension as the distance between the upper pressing roller 401 and the lower pressing roller 402 changes, and ensure that the upper pressing roller 401 and the lower pressing roller 402 always clamp and press the electrode 2000 tightly.

[0079] In some embodiments of this utility model, reference is made to Figures 1-4 As shown, the electrode bonding device further includes a cleaning mechanism 500. In the length direction of the electrode 2000, the cleaning mechanism 500 is at least partially disposed between the pressing mechanism 400 and the winding mechanism 300. The cleaning mechanism 500 includes an upper roller brush 501 and a lower roller brush 502. The upper roller brush 501 is rotatably disposed on one side of the electrode 2000 in the thickness direction, and the lower roller brush 502 is rotatably disposed on the other side of the electrode 2000 in the thickness direction.

[0080] Specifically, the upper roller brush 501 and the lower roller brush 502 of the cleaning mechanism 500 can be located between the pressing mechanism 400 and the winding mechanism 300. Before the electrode 2000 is wound up by the winding mechanism 300, it is cleaned again by the cleaning mechanism 500 to ensure the cleanliness of the electrode 2000 when it is wound up.

[0081] When the electrode 2000 passes through the cleaning mechanism 500, the upper roller brush 501 can perform roller brush cleaning on the upper surface of the electrode 2000, and the lower roller brush 502 can perform roller brush cleaning on the lower surface of the electrode 2000, removing dust, impurities, etc. from the surface of the electrode 2000 and the tape 11, so as to ensure the cleanliness of the surface of the electrode 2000 before winding.

[0082] In some embodiments of this utility model, reference is made to Figure 4 As shown, the cleaning mechanism 500 also includes: a housing 503, an upper vacuum cleaner 504 and a lower vacuum cleaner 505. An electrode 2000 is disposed in the housing 503 and divides the space inside the housing 503 into an upper cleaning chamber 5031 and a lower cleaning chamber 5032. An upper roller brush 501 is disposed in the upper cleaning chamber 5031 and a lower roller brush 502 is disposed in the lower cleaning chamber 5032. The upper vacuum cleaner 504 is connected to the upper cleaning chamber 5031 and is used to draw negative pressure from the upper cleaning chamber 5031. The lower vacuum cleaner 505 is connected to the lower cleaning chamber 5032 and is used to draw negative pressure from the lower cleaning chamber 5032.

[0083] Specifically, when the electrode 2000 passes through the outer shell 503, it divides the space inside the outer shell 503 into an upper cleaning chamber 5031 and a lower cleaning chamber 5032. The upper roller brush 501 is located in the upper cleaning chamber 5031. The upper vacuum cleaner 504 is connected to the upper cleaning chamber 5031 and is used to draw negative pressure into the upper cleaning chamber 5031. When the upper roller brush 501 cleans the electrode 2000, the dust and impurities on the electrode 2000 will fall into the upper cleaning chamber 5031 and then be sucked into the upper vacuum cleaner 504 under the negative pressure of the upper vacuum cleaner 504, so as to prevent the dust and impurities from falling back onto the upper surface of the electrode 2000 and improve the cleaning effect of the cleaning mechanism 500 on the electrode 2000.

[0084] The lower roller brush 502 is located inside the lower cleaning chamber 5032. The lower vacuum cleaner 505 is connected to the lower cleaning chamber 5032 and is used to draw negative pressure into the lower cleaning chamber 5032. When the lower roller brush 502 cleans the electrode 2000, the dust and impurities under the electrode 2000 will fall into the lower cleaning chamber 5032, and then be sucked into the lower vacuum cleaner 505 under the negative pressure, so as to prevent the dust and impurities from falling back onto the lower surface of the electrode 2000 and improve the cleaning effect of the cleaning mechanism 500 on the electrode 2000.

[0085] Reference Figure 4As shown, the upper pressing roller 401 can be disposed in the upper cleaning chamber 5031 in the housing 503, and the lower pressing roller 402 can be disposed in the lower cleaning chamber 5032 in the housing 503. The upper cleaning chamber 5031 and the lower cleaning chamber 5032 have a high degree of cleanliness to prevent external dust and impurities from being pressed into the electrode 2000 and the tape 11 by the pressing mechanism 400.

[0086] In some embodiments of this utility model (not shown in the figures), the electrode adhesive applicator further includes a tension adjustment mechanism. Along the length of the electrode 2000, the tension adjustment mechanism is located between the unwinding mechanism 200 and the adhesive applicator 100. The tension adjustment mechanism includes a tension roller, a tension sensor, and a tension adjusting element. The electrode 2000 is wound around the tension roller. The tension sensor is used to detect the tension value of the electrode 2000. The tension adjusting element is communicatively connected to the tension sensor and is used to drive the movement of the tension roller so that the tension value of the electrode 2000 is within a preset range.

[0087] Specifically, the tension adjustment mechanism is located between the unwinding mechanism 200 and the adhesive application mechanism 100. The tension adjustment mechanism can adjust the tension of the electrode 2000 so that the electrode 2000 remains taut when it enters the adhesive application mechanism 100, thus preventing the electrode 2000 from wrinkling or stretching due to unstable tension.

[0088] An electrode 2000 is wound around a tension roller. A tension sensor, which has a strain gauge, can be mounted on the bearing housing of the tension roller. The strain gauge can calculate the tension value of the electrode 2000 by measuring the force applied to the tension roller. A tension adjusting component is communicatively connected to the tension sensor. The tension adjusting component can obtain the tension value of the electrode 2000 through the tension sensor. When the tension value is within a preset range, the electrode 2000 remains taut, and the tension roller maintains its position. When the tension value is outside the preset range, the tension adjusting component can drive the tension roller to move, thereby adjusting the tension value of the electrode 2000 to return it to the preset range, thus maintaining stable tension of the electrode 2000. Optionally, the tension adjusting component can be a tensioning arm with a CNC chip.

[0089] In some embodiments of this utility model, the electrode adhesive application device further includes a frame, and the unwinding mechanism 200, the adhesive application mechanism 100, the winding mechanism 300, the pretreatment mechanism, the pressing mechanism 400, the cleaning mechanism 500, and the tension adjustment mechanism can all be installed on the frame so that the electrode adhesive application device forms a whole and improves the working accuracy of the electrode adhesive application device.

[0090] The electrode adhesive application device according to the embodiments of this utility model has at least the following technical effects:

[0091] 1. The adhesive applicator 100 can perform double-sided synchronous adhesive applicator on the electrode 2000, that is, it can apply adhesive to the upper and lower surfaces of the electrode 2000 at the same time without flipping the electrode 2000, thus realizing the automated operation of double-sided adhesive applicator on the electrode 2000 and greatly improving the adhesive applicator efficiency.

[0092] 2. The pretreatment mechanism can clean and level the electrode 2000, ensuring the cleanliness and flatness of the electrode 2000 surface, improving the bonding quality between the tape 11 and the electrode 2000, and avoiding the problem of weak bonding caused by impurities and wrinkles.

[0093] 3. The tension adjustment mechanism can adjust the tension of the electrode 2000 in real time, ensuring that the tension of the electrode 2000 is stable during the conveying and adhesive application process. This avoids wrinkles and stretching of the electrode 2000 due to unstable tension, thus improving the adhesive application accuracy.

[0094] 4. The pressing mechanism 400 can tightly press the tape 11 and the electrode 2000 together to avoid air bubbles, further ensuring the adhesion between the tape 11 and the electrode 2000 and improving the production quality of the electrode 2000.

[0095] 5. The entire device has a compact structure, is easy to operate, can achieve continuous production, reduces labor costs, and has high practical value and promising prospects for promotion.
