Description

Technical Field

[0001] This invention relates to the field of lithium battery processing technology, and in particular to a novel irregular-shaped adhesive bonding mechanism for lithium batteries. Background Technology

[0002] In the lithium battery production process, especially in the soft-pack process of 3C mobile phone lithium batteries, applying irregularly shaped protective adhesive is a key step to ensure the stability, insulation, and safety of the battery structure. With the development of AI mobile phone technology and the accelerated pace of electronic product upgrades, the demand for soft-pack lithium batteries has increased, placing higher demands on the precision and efficiency of the adhesive application process.

[0003] Currently, lithium battery cells require the application of irregularly shaped adhesive tapes at multiple locations to protect them from short circuits. However, existing tape application processes face significant challenges when handling these irregularly shaped tapes: First, due to their irregular shape and soft texture, manual application is difficult to hold, prone to wrinkling, resulting in a high failure rate, and failing to meet the stringent precision requirements of end-user manufacturers. Second, in terms of automation, most existing tape application mechanisms lack the ability to process multiple surfaces simultaneously, typically requiring multiple mechanisms to apply the tape in stages. This step-by-step approach not only leads to a complex and costly tape application system but also results in low efficiency and unsatisfactory overall yield.

[0004] Furthermore, the tape feeding and conveying process is also crucial in automated tape application. Existing technologies often require a laterally moving robotic arm to grip and pull the tape for feeding. This feeding process is cumbersome and prone to poor bonding, tape wrinkles, or misalignment due to unstable tension control or path deviation, making it difficult to meet the high-precision and high-efficiency application requirements of irregularly shaped tapes.

[0005] Therefore, there is an urgent need in this field for a new type of adhesive application mechanism that can achieve high-precision adhesive application in an integrated, multi-dimensional manner, and complete the application of complex and irregularly shaped adhesive tapes in one go, fundamentally solving the problems of efficiency, yield and accuracy.

[0019] Beneficial effects:

[0020] 1. This invention discloses a novel irregularly shaped adhesive applicator for lithium batteries. Through the coordinated action of a clamping frame, a first pressure roller, a second pressure roller, and a pulley system, it achieves stable clamping, precise feeding, and controllable application of soft, irregularly shaped adhesive tape. Throughout the process, the tape tension remains stable and the path is precise, effectively avoiding problems such as tape wrinkling, stretching deformation, or positional misalignment that are easily caused by manual or traditional robotic feeding methods. This meets the extremely high requirements of end-user manufacturers for adhesive application precision. Simultaneously, it can complete the application of adhesive tape to multiple different dimensions of the lithium battery in one operation, avoiding the cumulative errors and time consumption caused by multiple positioning and bonding processes. This significantly improves application efficiency and first-pass yield, while simplifying the equipment structure and reducing costs.

[0021] 2. The novel irregular-shaped adhesive applicator for lithium batteries of the present invention uses a first electric cylinder to drive a first lifting frame to drive a first pressure roller to achieve initial bonding, which can quickly pre-fix the adhesive tape on the surface of the lithium battery, laying the foundation for the subsequent compaction process; in conjunction with a third electric cylinder to drive a second lifting frame to drive a second pressure roller for secondary compaction, the gap between the adhesive tape and the surface of the lithium battery can be effectively eliminated. At the same time, the rotating drum moves synchronously with the second lifting frame and assists in rolling and flattening, further expelling air from the adhesive tape and the surface of the battery.

[0022] 3. The novel irregular-shaped adhesive applicator for lithium batteries of the present invention uses a clamping frame linked with a second lifting frame. During the adhesive application process, a fourth electric cylinder drives the clamping plate to move downwards and clamp the end of the adhesive tape, which can effectively prevent the adhesive tape from retracting or shifting due to changes in conveying tension, and ensure the stability of the adhesive tape conveying path. After the adhesive application is completed, the clamping frame moves upwards to cooperate with the cutter for cutting. After cutting, the first pressure roller presses the remaining adhesive tape to adhere. Then, the clamping plate clamps the adhesive tape again, and the clamping frame moves downwards to achieve forward feeding, so that the adhesive tape is always kept taut, avoiding the adhesive application position deviation caused by the loosening or shifting of the adhesive tape in traditional feeding.

[0036] Reference Figures 1-6An embodiment of the present invention provides a novel irregular-shaped adhesive applicator for lithium batteries, including a base 1, a mounting frame 103 on the top of the base 1; an adhesive applicator mounted on the mounting frame 103, which applies adhesive to the lithium battery via a first pressure roller 502 and a second pressure roller 508; and a pulley system mounted on the mounting frame 103, which limits the conveyor belt during conveying via a first limiting roller 2, a first limiting cylinder 203, a second limiting cylinder 206, and a second limiting roller 210.

[0037] In this embodiment, the clamping frame 512 and the first pressure roller 502 work together to ensure the stability and accuracy of the continuous adhesive application process. After cutting, the first pressure roller 502 finishes the bonding; the clamping plate 514 clamps and moves down to feed the material; the first pressure roller 502 then bonds the new battery again in a continuous action, which greatly improves the efficiency of tape feeding and cutting in mass production.

[0038] In this example, the first electric cylinder 5 drives the first lifting frame 501 to drive the first pressure roller 502 to achieve initial bonding, which can quickly pre-fix the tape on the lithium battery surface, laying the foundation for the subsequent compaction process; in conjunction with the third electric cylinder 506 driving the second lifting frame 509 to drive the second pressure roller 508 for secondary compaction, the gap between the tape and the lithium battery surface can be effectively eliminated. At the same time, the rotating drum 511 moves synchronously with the second lifting frame 509 and assists in rolling and flattening, further expelling the air from the tape and the battery surface.

[0039] In this example, the clamping frame 512 is linked with the second lifting frame 509. During the adhesive application process, the fourth electric cylinder 513 drives the clamping plate 514 to move down and clamp the end of the tape, which can effectively prevent the tape from backing up or shifting due to changes in conveying tension, and ensure the stability of the tape conveying path. After the adhesive application is completed, the clamping frame 512 moves up to cooperate with the cutter 505 to cut. After cutting, the first pressure roller 502 presses the remaining tape together. Then, the clamping plate 514 clamps the tape again and the clamping frame 512 moves down to feed forward, so that the tape is always kept taut and avoids the deviation in the adhesive application position caused by the looseness and shift of the tape in traditional feeding.

[0040] This invention provides a novel irregular-shaped adhesive applicator for lithium batteries, comprising a second movable frame 408, a first electric cylinder 5, a first lifting frame 501, a first pressure roller 502, a first connecting frame 503, a second electric cylinder 504, a cutter 505, a third electric cylinder 506, a second lifting frame 509, a second connecting frame 507, a second pressure roller 508, a clamping frame 512, a fourth electric cylinder 513, and a clamping plate 514. The first electric cylinder 5 is fixedly mounted on one side of the second movable frame 408, the first lifting frame 501 is fixedly mounted on the output end of the first electric cylinder 508, the first pressure roller 502 is rotatably mounted on the bottom of the first lifting frame 501, and the first connecting frame 503 is fixedly mounted on the first lifting frame 508. On one side of the frame 501, the second electric cylinder 504 is fixedly installed at the bottom of the first connecting frame 503, and a knife holder is fixedly installed at the output end of the second electric cylinder 504. The cutter 505 is fixedly installed on one side of the knife holder. The third electric cylinder 506 is fixedly installed on the other side of the second moving frame 408. The second lifting frame 509 is fixedly installed at the output end of the third electric cylinder 506. The second connecting frame 507 is fixedly installed on one side of the second lifting frame 509. The second pressure roller 508 is rotatably installed at the bottom of the second connecting frame 507. The clamping frame 512 is fixedly installed on the other side of the second lifting frame 509. The fourth electric cylinder 513 is fixedly installed on the top of the inner wall of the clamping frame 512. The clamping plate 514 is fixedly installed at the output end of the fourth electric cylinder 513.

[0041] In this embodiment, the first electric cylinder 5 drives the first lifting frame 501 to move up and down, which in turn drives the first pressure roller 502 to press the tape and initially attach the tape to the surface of the lithium battery; the third electric cylinder 506 drives the second lifting frame 509 to move up and down, and the second pressure roller 508 further compacts the tape to ensure a firm fit. At the same time, the rotating drum 511 assists in rolling and flattening the tape to avoid the generation of air bubbles in the tape.

[0042] In this example, the clamping frame 512 moves up and down with the second lifting frame 509, and the fourth electric cylinder 513 drives the clamping plate 514 to move down, which can clamp and fix the end of the tape during the adhesive application process to prevent the tape from retracting. After the adhesive application is completed, the clamping frame 512 moves up, and the second electric cylinder 504 drives the cutter 505 to cut the tape position between the clamping frame 512 and the first pressure roller 502 laterally. After the cutting is completed, the first pressure roller 502 presses and adheres the remaining part of the cut tape to the lithium battery. Then, the clamping plate 514 in the clamping frame 512 fixes the tape in the clamping frame 512. The clamping frame 512 moves down to feed the tape forward. The tape remaining on one side of the clamping frame 512 is located below the first pressure roller 502. The first pressure roller 502 moves down and can adhere one end of the tape to the new lithium battery again.

[0043] This invention provides a novel irregular-shaped adhesive applicator for lithium batteries in an embodiment.

[0044] In this embodiment, the drive motor 401 can be a servo motor, which drives the first moving frame 403 to move horizontally along the limiting slide rail 402 through the worm gear transmission structure in the first mounting shell 4. One side of the first moving frame 403 is threadedly connected to the worm gear in the first mounting shell 4, so as to realize the horizontal position fine adjustment of the adhesive application mechanism and adapt to the needs of different adhesive application areas.

[0045] The rotating motor 407 can be a servo motor. A worm gear is rotatably mounted in the second mounting housing 405. The top of the worm gear is connected to the output end of the first transmission box 406. The rotating motor 407 drives the worm gear in the second mounting housing 405 through the gear transmission structure in the first transmission box 406, thereby causing the second moving frame 408 to move up and down. One side of the second moving frame 408 is threadedly connected to the worm gear in the second mounting housing 405. The height of the adhesive applicator can be adjusted to meet the adhesive applicator requirements of lithium batteries of different thicknesses.

The movable base plate 101 can be manually or through an additional drive structure to adjust its position on the base 1 through the cooperation of the first limit block 102 and the first slide rail, further expanding the adaptability range of the mechanism.

[0048] This invention provides a novel irregular-shaped adhesive applicator for lithium batteries, comprising a pulley system including a first limiting roller 2, a first mounting plate 201, a first pulley 202, a first limiting cylinder 203, a second mounting plate 204, a second pulley 205, a second limiting cylinder 206, a limiting frame 207, a speed sensor 208, a separation support roller 209, and several second limiting rollers 210.

The first mounting plate 201 is fixedly mounted on one side of the mounting frame 103, located at the bottom of the first limiting roller 2. The first pulley 202 and the first limiting cylinder 203 are both slidably mounted on one side of the first mounting plate 201, with the first limiting cylinder 203 located at the bottom of the first mounting plate 205. The top of the pulley 202, the second mounting plate 204 is fixedly installed on one side of the mounting frame 103, the second mounting plate 204 is located at the bottom of the take-up reel 107, the second pulley 205 and the second limiting cylinder 206 are both rotatably installed on one side of the second mounting plate 204, the second limiting cylinder 206 is located on the top of the second pulley 205, the separation support roller 209 is rotatably installed on one side of the mounting frame 103, the limiting frame 207 is fixedly installed on one side of the mounting frame 103, the separation support roller 209 and the limiting frame 207 are located between the first mounting plate 201 and the second mounting plate 204, the separation support roller 209 is located at the bottom of the limiting frame 207, the speed sensor 208 is fixedly installed on the inner wall of the limiting frame 207, and several second limiting rollers 210 are rotatably installed on the bottom side of the mounting frame 103.

[0049] In this example, a first motor 104 is fixedly installed on the top of one side of the mounting frame 103.

Both the first motor 104 and the second motor 106 can be servo motors. Through synchronous speed control, the tape conveying speed is matched with the adhesive application rhythm to avoid wrinkles and stretching problems caused by the tape being conveyed too fast or too slow.

[0050] In this example, the first limiting roller 2, the first limiting cylinder 203, the second limiting cylinder 206, and the second limiting roller 210 form a multi-level limiting structure to precisely constrain the conveyor belt path, prevent belt deviation, and ensure adhesive application accuracy.

[0051] The speed sensor 208 uses a photoelectric sensor of model E3Z-LS63 to detect the conveyor belt speed in real time and feed the signal back to the control system to adjust the speed of the first motor 104 and the second motor 106 to ensure the conveyor belt speed is stable.

[0052] The tape and release paper are initially separated at the separation support roller 209. When the tape and release paper are separated, the separation support roller 209 supports them on one side to facilitate the smooth progress of the release paper winding process.

[0053] In this example, a second support 602 is provided on one side of the base 1. A turntable 603 is rotatably mounted on the top of the second support 602, and a second transmission box 606 is fixedly mounted on the bottom of the second support 602. The bottom of the turntable 603 is mounted on the output end of the second transmission box 606. A fourth motor 607 is fixedly mounted on one side of the bottom of the second transmission box 606. The turntable 603 is driven to rotate on the top of the second support 602 by the fourth motor 607. The fourth motor 607 is a servo motor. The fourth motor 607 drives the turntable 603 to rotate intermittently through the gear transmission structure in the second transmission box 606, realizing the cyclic conveying of the workbench 604. This, together with the adhesive applicator, completes the automated continuous adhesive applicator operation, improving production efficiency.

[0054] Description: Several worktables 604 are fixedly installed on the top of the turntable 603. A first bracket 6 is set on one side of the second bracket 602. A camera 601 is fixedly installed on the top of the first bracket 6. The camera 601 is located directly above the turntable 603, and the lens of the camera 601 is aimed at the worktables 604 on the turntable 603. The camera 601 can be a CCD camera. The shooting position of the camera 601 needs to be precisely matched with the movement trajectory of the turntable 603 and the worktables 604 and the requirements of the adhesive application process. The shooting field of the camera 601 needs to cover the entire surface of the worktable 604, and the image resolution needs to meet the requirement of recognizing the positional deviation of the lithium battery edge within ±0.05mm. Through the image processing algorithm of the camera, the actual placement position of the lithium battery on the worktable 604 can be captured in real time and compared with the preset standard adhesive application position to calculate the positional offset, including the offset in the X-axis and Y-axis directions and the angle deflection. Then the offset data is fed back to the control system, which adjusts the horizontal position of the mounting bracket 103 to ensure that the adhesive application mechanism is precisely aligned with the area of ​​the lithium battery to be adhesiveed.

[0055] In this example, the worktable 604 can be a T-slot worktable. The worktable 604 can be equipped with a fixture. The shape and size of the fixture can be selected according to the size of the lithium battery. The lithium battery is transported to the worktable 604 by conventional means of transporting lithium batteries in the prior art, such as using a robotic arm to grip and transport the lithium battery.
