This arc-shaped battery cell offers better space utilization efficiency in practical applications, but it requires the use of high-temperature tape to fix the cell during production to ensure its structural stability.

[0003] Existing adhesive application equipment mainly uses a C-type adhesive application mechanism. A servo motor controls the application head to pre-apply tape to the cell surface, then a servo motor controls the tape length, and finally, a servo motor controls the application head's forward / backward movement and lifting axis to stably attach the tape to the top, bottom, and sides of the cell. However, this method is only suitable for flat cells. Because the application head cannot adapt to curved surfaces, it easily leads to quality problems such as bubbles and wrinkles during the application process to curved cells, failing to meet the requirements of the curved cell application process. Therefore, there is an urgent need for an adhesive application device that can adapt to curved cell surfaces to achieve high-quality adhesive application to curved cells. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0033] Reference Figure 1 , Figure 2 An adhesive applicator includes a positioning component 200, an adhesive supply component 300, and an adhesive application component 400. The positioning component 200 is used to fix an arc-shaped battery cell; the adhesive supply component 300 is used to pre-set adhesive tape; the adhesive application component 400 is movable relative to the positioning component 200 in a horizontal plane and includes a moving unit 410; and an adhesive application unit 430, the adhesive application unit 430 including a rotating mechanism 431; an adsorption component 4314 disposed at the output end of the rotating mechanism 431; and pressing components 4315 disposed on both sides of the adsorption component 4314; wherein the rotating mechanism 431 is used to adjust the angle of the adsorption component 4314, and the pressing components 4315 are used to adhere the adhesive tape to the arc-shaped battery cell.

[0034] Understandably, in this adhesive application device, the positioning component 200 first fixes the arc-shaped battery cell to be adhesiveped in the designated position, while the adhesive supply component 300 pre-sets the adhesive tape to be applied. (Refer to...) Figure 3 , 4 The adhesive application assembly 400, through its moving unit 410, can move relative to the positioning assembly 200 in the horizontal plane to adjust the adhesive application position. (See reference...) Figure 5 , 6When adhesive application is required, the adsorption component 4314 in the adhesive application unit 430 first adsorbs the adhesive tape provided by the adhesive supply assembly 300. Then, the rotation mechanism 431 rotates the adsorption component 4314 to adjust its angle, matching the curvature of the curved battery cell surface. For example, when applying adhesive to the top area of ​​the curved battery cell, the rotation mechanism 431 adjusts the adsorption component 4314 to a horizontal position, while when applying adhesive to the curved transition area, it adjusts the adsorption component 4314 to the corresponding tilt angle. After angle adjustment, the pressing components 4315 on both sides of the adsorption component 4314 firmly press the adhesive tape onto the curved battery cell surface, ensuring a tight fit between the tape and the surface, preventing air bubbles or wrinkles.

[0035] In some embodiments, refer to Figure 5 , 6 The rotating mechanism 431 includes: a rotary motor 4311; and a connecting seat 4312 connected to the output shaft of the rotary motor 4311; wherein, the adsorption component 4314 is connected to the connecting seat 4312 via a spring 4313, the spring 4313 being compressed during the movement of the adhesive application assembly 400 toward the arc-shaped battery cell, and driving the adsorption component 4314 to reset after the adhesive application is completed; specifically, the adsorption component 4314 is an adhesive tape suction block, the adhesive tape suction block having a vacuum adsorption channel; and a vacuum pump communicating with the vacuum adsorption channel. It can be understood that the output shaft of the rotary motor 4311 is connected to the connecting seat 4312 to drive the connecting seat 4312 to rotate, thereby achieving angle adjustment. The adsorption component 4314 takes the form of a tape suction block and is connected to the connecting seat 4312 via a spring 4313. When the tape application assembly 400 moves towards the curved battery cell to perform the tape application operation, the spring 4313 is compressed, which applies appropriate pressure to the tape suction block to ensure the stability of the tape application process. After the tape application is completed, the elasticity of the spring 4313 causes the tape suction block to automatically return to its initial position. The tape suction block has a vacuum adsorption channel inside, which is connected to a vacuum pump. For example, during the actual tape application process, when tape needs to be adsorbed, the vacuum pump works to generate negative pressure, which firmly adsorbs the tape onto the surface of the tape suction block through the vacuum adsorption channel. After the tape is completely adhered to the surface of the curved battery cell, the vacuum state is released, completing a single tape application operation.

[0036] Among them, the rotary motor 4311 adopts a servo motor combined with a reduction mechanism. The servo motor can provide precise angle control, and the reduction mechanism reduces the speed and increases the torque, thereby achieving high-precision adjustment of the angle of the adsorption component 4314. For example, when the adhesive application assembly 400 needs to apply adhesive to different positions of the arc-shaped battery cell, the servo motor can precisely control the rotation angle to adapt to any angle requirement within the shape range of the arc-shaped battery cell 100.

[0037] The tape suction block, connected to a vacuum pump via its internal vacuum adsorption channel, generates a stable negative pressure adsorption force, ensuring the tape is evenly and firmly adsorbed onto the surface of the suction block, preventing the tape from shifting or wrinkling during movement and rotation. Simultaneously, the vacuum adsorption method does not contaminate or damage the adhesive surface of the tape, maintaining its adhesive properties. Furthermore, when the tape needs to be released, simply releasing the vacuum allows for quick and accurate release onto the curved battery cell surface, improving the precision and efficiency of tape application.

[0038] In some embodiments, refer to Figure 5 , 6 The pressing component 4315 includes: a first smoothing block 4315a and a second smoothing block 4315b; and a clamping cylinder 4315b for driving the first smoothing block 4315a and the second smoothing block 4315b to open and close; wherein, when the clamping cylinder 4315b drives the first smoothing block 4315a and the second smoothing block 4315b to open, a safe gap is formed between the first smoothing block 4315a and the second smoothing block 4315b and the arc-shaped battery cell for the smoothing block to extend into; when the clamping cylinder 4315b drives the first smoothing block 4315a and the second smoothing block 4315b to clamp, the first smoothing block 4315a and the second smoothing block 4315b press the tape tightly onto the surface of the arc-shaped battery cell. Understandably, when the adhesive application assembly 400 moves near the curved battery cell, the clamping cylinder 4315b first drives the first smoothing block 4315a and the second smoothing block 4315b to open. At this time, a safe gap is formed between the first smoothing block 4315a, the second smoothing block 4315b and the curved battery cell, allowing the adhesive application assembly 400 to smoothly approach the curved battery cell without interference. After the tape suction block initially attaches the tape to the surface of the curved battery cell, the clamping cylinder 4315b drives the first smoothing block 4315a and the second smoothing block 4315b to perform a clamping action. For example, when the adhesive application assembly 400 delivers the tape to the surface of the curved battery cell, the two smoothing blocks will move inward synchronously, firmly pressing the tape onto the surface of the curved battery cell. Through bidirectional compression, the tape is ensured to fully adhere to the surface of the curved battery cell, effectively preventing quality problems such as bubbles and wrinkles in the tape, thereby ensuring the reliability and stability of the adhesive application.

[0039] In some embodiments, refer to Figure 7 , 8The adhesive supply assembly 300 includes: a tape unwinding section 310; a cutting section 320 disposed at the discharge end of the tape unwinding section 310; and a tape pulling section 330 disposed at the discharge end of the cutting section 320, used to pull the tape out to a preset length. It can be understood that in the adhesive supply assembly 300, the tape unwinding section 310 is responsible for storing and releasing the tape roll, guiding the tape smoothly to the cutting section 320, which is disposed at the discharge end of the tape unwinding section 310, and used to cut the continuous tape to a predetermined size. The tape pulling section 330, disposed at the discharge end of the cutting section 320, is responsible for pulling the tape out to a preset length to ensure that the length of the tape supplied each time meets the adhesive requirements of the curved battery cell. For example, when it is necessary to apply adhesive to an arc-shaped battery cell, the tape is first pulled out to the required length by the tape pulling part 330, and then the cutting part 320 performs a cutting action to separate the single section of tape from the tape roll. Then, the tape suction block of the tape application assembly 400 conveys the cut tape to the surface of the arc-shaped battery cell through vacuum adsorption, completing a complete tape supply process. This design ensures the accuracy and continuity of tape supply and improves the efficiency of tape application.

[0040] Furthermore, refer to Figure 2 The adhesive-pulling jaw 332 is connected to the adhesive-pulling cylinder 331. The extension and retraction of the adhesive-pulling cylinder 331 drives the adhesive-pulling jaw 332 to perform linear reciprocating motion, thereby achieving precise pulling of the adhesive tape. For example, in actual operation, when it is necessary to pull the adhesive tape to a preset length, the adhesive-pulling jaw 332 first clamps the adhesive tape, and then the adhesive-pulling cylinder 331 drives the adhesive-pulling jaw 332 to move in a straight line, pulling the adhesive tape from the tape unwinding section 310 to the required length. After the tape length reaches the preset value, the cutting section 320 performs a cutting action, completing a single adhesive supply process.

[0041] In some embodiments, refer to Figure 1 , 2The positioning component 200 includes a first positioning seat 210 and a second positioning seat 220, both of which have an arc-shaped structure; and a positioning cylinder 230 connected to the first positioning seat 210. The positioning cylinder 230 drives the first positioning seat 210 to move toward the second positioning seat 220, thereby clamping the arc-shaped battery cell through the arc-shaped structures of the first positioning seat 210 and the second positioning seat 220. It can be understood that when the arc-shaped battery cell needs to be positioned and fixed, the arc-shaped battery cell is first placed on the second positioning seat 220, and then the positioning cylinder 230 drives the first positioning seat 210 to move toward the second positioning seat 220. The arc-shaped structures of the two positioning seats form a surrounding clamping effect on the arc-shaped battery cell. Since the arc-shaped structure of the positioning seat matches the shape of the arc-shaped battery cell, the position of the arc-shaped battery cell can be accurately positioned and fixed, ensuring that the arc-shaped battery cell remains stable during subsequent adhesive application and does not shift position, thus ensuring the accuracy and reliability of adhesive application.

[0042] In some embodiments, refer to Figure 3 , 4 The moving unit 410 includes: a first guide rail 411 and a first sliding platform 412 slidably engaged with the first guide rail 411; a second guide rail 413 and a second sliding platform 414 slidably engaged with the second guide rail 413; wherein, the second guide rail 413 is fixedly disposed on the first sliding platform 412, and the adhesive application unit 430 is disposed on the second sliding platform 414, and the adhesive application assembly 400 can move relative to the positioning assembly 200 in the forward and backward and left and right directions. It can be understood that the first guide rail 411 can drive the first sliding platform 412 to move in the forward and backward direction, while the second guide rail 413 can drive the second sliding platform 414 to move in the left and right direction. The movements in the two directions are independent and can be combined, thereby enabling the adhesive application assembly 400 to accurately position itself at any adhesive application location on the curved battery cell. This design not only improves the flexibility of adjusting the adhesive application position but also ensures the stability and accuracy of the movement trajectory of the adhesive application assembly 400, effectively meeting the positioning requirements of the curved battery cell adhesive application process.

[0043] Furthermore, a height adjustment plate 420 is used in conjunction with multiple adjustment holes 421. The height adjustment plate 420 is fixedly connected to the second sliding platform 414. Multiple adjustment holes 421 are provided on the height adjustment plate 420, and the adhesive application unit 430 is adjustablely connected to the height adjustment plate 420 through these adjustment holes 421. For example, when it is necessary to adjust the working height of the adhesive application assembly 400, the fasteners between the adhesive application unit 430 and the height adjustment plate 420 can be loosened. According to the size requirements of the arc-shaped battery cell, the appropriate adjustment hole 421 position is selected to reinstall and fix the adhesive application unit 430. By changing the installation position of the adhesive application unit 430 on the height adjustment plate 420, the height of the adhesive application assembly 400 can be adjusted in a step-like manner. This design can not only adapt to the adhesive application requirements of arc-shaped battery cells of different specifications, but also ensure that the adhesive application assembly 400 and the arc-shaped battery cell maintain the optimal working distance through a simple mechanical adjustment method, thereby improving the adaptability and reliability of the adhesive application process.

[0044] An adhesive applicator includes the aforementioned adhesive applicator, which integrates core components such as an adhesive supply component 300, a positioning component 200, a moving unit 410, and an adhesive applicator unit 430 to form a complete automated adhesive applicator solution. For example, in practical applications, this adhesive applicator can automatically complete a series of processes, including positioning of curved battery cells, supplying adhesive tape, cutting, and precise application. The adhesive supply component 300 is responsible for unwinding and cutting the adhesive tape; the positioning component 200 ensures the stable placement of the curved battery cell through an arc-shaped positioning seat; the moving unit 410 achieves two-dimensional precise positioning of the adhesive applicator component 400; and the adhesive applicator unit 430 can adjust its working height as needed. The organic combination of these functional modules enables the entire adhesive applicator process to be completed efficiently and accurately, significantly improving the automation level and production efficiency of the curved battery cell adhesive applicator process.
