Description

Technical Field

[0001] This invention relates to the field of applying double-sided adhesive to mica sheets, specifically to a double-sided adhesive bonding device for mica in power batteries. Background Technology

[0002] Currently, the traditional process of applying double-sided tape to mica sheets typically involves precisely placing the mica sheets within a specific mold. Then, a double-sided tape bonding device relies on precise movement along the X, Y, and Z axes to achieve accurate adhesion between the double-sided tape and the mica sheet. However, this method suffers from a significant efficiency bottleneck: once a set of mica sheets has been coated with double-sided tape, the entire production line must be paused so that operators can manually remove the finished mica sheets from the mold and replace them with new ones ready for double-sided tape. This process is not only time-consuming and labor-intensive, but the frequent interruptions also severely impact overall production efficiency.

[0003] Further complicating matters is the fact that different sizes of mica sheets require specific molds, significantly increasing the complexity of production preparation. Each time different sizes of mica sheets need to be processed, the corresponding mold must be changed, which not only increases production costs but also limits the flexibility and adaptability of the production line. The mold changeover process also requires time and manpower, further reducing production efficiency and potentially introducing fitting accuracy problems due to mold mismatch.

[0004] Therefore, we propose a double-sided adhesive bonding device for mica in power batteries to solve the above problems. Summary of the Invention

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Please refer to the following: Figures 1 to 5 A double-sided adhesive bonding device for mica in power batteries mainly consists of a frame 1 as the main support structure. Inside the frame 1, a conveying device 2 is carefully configured to stably and continuously convey the mica sheets.

[0032] The conveying device 2 consists of a driving roller 29, a first driven roller 30, and a second driven roller 31, all of which are securely mounted on the frame 1 via a rotatable connection. Specifically, the first driven roller 30 is cleverly positioned between the driving roller 29 and the second driven roller 31, forming a highly efficient transmission chain. An electric motor 39 is also fixed on the frame 1, its output end tightly connected to one end of the driving roller 29, providing a continuous and stable power source for the entire conveying process. Between the driving roller 29 and the first driven roller 30, several parallel belts 32 with a high coefficient of friction are used for transmission, ensuring that the mica sheets adhere firmly to the belts during conveying and preventing slippage. Between the driving roller 29 and the second driven roller 31, several parallel belts 33 with a low coefficient of friction are used for transmission. This design allows the mica sheets to easily slide on the low-friction belts 33 when position adjustments are needed, improving operational flexibility.

[0033] To further optimize the conveying and bonding effect of mica sheets, two sets of adjustment devices 34 are symmetrically installed on the frame 1. These adjustment devices 34 are cleverly positioned away from the high-friction belt 32 to avoid any interference with the normal conveying of the mica sheets. Each adjustment device 34 includes an adjustment cylinder 35, the output end of which is fixed with an adjustment plate 36. Through the precise control of the adjustment cylinder 35, the adjustment plate 36 can easily squeeze the edge of the mica sheet, thereby achieving precise adjustment of the mica sheet position.

[0034] At the top of the frame 1, a vertical plate 3 is fixed, and a position adjustment cylinder 4 is securely mounted on one side of the vertical plate 3. The output end of the position adjustment cylinder 4 is tightly connected to the mounting plate 5, allowing the mounting plate 5 to be flexibly adjusted in position according to actual needs, further improving the adaptability and flexibility of the bonding device. An ear plate 6 is fixed to one side of the mounting plate 5, and a fixing rod 7 is fixed to the top of the ear plate 6. A sliding plate 8 is slidably connected to the fixing rod 7, and a spring 9 is also sleeved on the outside of the fixing rod 7. The two ends of the spring 9 are in close contact with the ear plate 6 and the sliding plate 8, respectively, providing stable support and cushioning for the sliding plate 8, ensuring that the double-sided adhesive feeding device 10 can move up and down smoothly.

[0035] On the slide plate 8, we have carefully designed a double-sided adhesive dispensing device 10. This device consists of a connecting plate 19, a dispensing shaft 20, a double-sided adhesive roll 21, an extraction box 22, and inclined and horizontal sections 23 and 24, respectively. The connecting plate 19 is fixed to the slide plate 8, and the dispensing shaft 20 is installed on one side of the connecting plate 19 to support the double-sided adhesive roll 21. The extraction box 22 is fixed to the other side of the connecting plate 19, and its side and bottom are respectively provided with inclined sections 23 and horizontal sections 24, which are in close contact with the double-sided adhesive. Both the inclined sections 23 and horizontal sections 24 are provided with extraction holes 25, which communicate with the interior of the extraction box 22. With the assistance of the fan 26, the double-sided adhesive is firmly adsorbed onto the inclined sections 23 and horizontal sections 24, ensuring the stability and accuracy of the bonding process.

[0036] To enable automated cutting of double-sided tape, we installed a double-sided tape cutting device 18 on the mounting plate 5. This device consists of a cutting cylinder 27 and a laser cutting head 28, which can quickly and accurately cut the double-sided tape when needed, improving the automation and efficiency of the entire bonding process.

[0037] Furthermore, we have carefully optimized some details of the device. For example, the gap between the horizontal part 24 and the bottom edge of the connecting plate 19 is slightly smaller than the thickness of the double-sided adhesive. This design ensures that the double-sided adhesive can be smoothly released from the feeding shaft 20 and adhered to the mica sheet. Meanwhile, the gap between the inclined part 23 and the side edge of the connecting plate 19 is slightly larger than the thickness of the double-sided adhesive, avoiding problems such as the double-sided adhesive getting stuck or damaged due to insufficient gap. At the same time, the connection between the horizontal part 24 and the inclined part 23 adopts an arc-shaped transition design, effectively preventing the double-sided adhesive from bending or being damaged during the transition process, thus improving the bonding quality.

[0038] The driving device 11 includes a lever 13 hinged to the mounting plate 5 via a rotating shaft 12. A U-shaped seat 14 is slidably connected to one side of the mounting plate 5 along the vertical direction. One end of the lever 13 contacts the top of the U-shaped seat 14. A roller 15 that cooperates with a mica sheet is rotatably connected to the inner side of the U-shaped seat 14. The mounting plate 5 is provided with an arc-shaped hole 16. A driving rod 17 is fixed to the end of the lever 13 away from the U-shaped seat 14. The driving rod 17 passes through the arc-shaped hole 16 and contacts the top of the slide plate 8. The mounting plate 5 is provided with a double-sided adhesive cutting device 18.

[0039] One end of lever 13 is designed to be cylindrical and tangent to the top of U-shaped seat 14. This design greatly reduces friction, allowing lever 13 to rotate more smoothly. U-shaped seat 14 is slidably connected to groove 37 on mounting plate 5 via slider 38, ensuring smooth and accurate up-and-down movement. Furthermore, the distance between shaft 12 and U-shaped seat 14 is cleverly set to be less than the distance between shaft 12 and drive rod 17. This design allows double-sided tape dispensing device 10 to move up and down a sufficient distance, thus avoiding unnecessary contact or interference between the double-sided tape and conveying device 2, ensuring smooth bonding.

[0040] The working principle of this mica double-sided adhesive bonding device for power batteries is as follows:

[0041] I. Start-up and Delivery

[0042] When the device is started, the motor 39 starts working, and its output end drives the drive roller 29 to rotate.

[0043] The rotation of the driving roller 29 is transmitted to the first driven roller 30 via the high-friction belt 32, and also to the second driven roller 31 via the low-friction belt 33.

[0044] The mica sheet to be coated with double-sided tape is placed at one end of the conveyor device 2. Due to the low coefficient of friction of the low-friction belt 33, the mica sheet can slide easily on its surface.

[0045] II. Position Adjustment and Conveying Continue

[0046] Through the coordinated action of two adjusting cylinders 35, their output ends drive the adjusting plate 36 to squeeze the edge of the mica sheet, thereby precisely adjusting the position of the mica sheet.

[0047] As the motor 39 continues to drive, the driving roller 29, the first driven roller 30 and the second driven roller 31 continue to rotate, driving the low-friction belt 33 and the high-friction belt 32 to transport the mica sheets together.

[0048] When the mica sheet moves onto the high-friction belt 32, due to its high surface friction coefficient and relatively large contact area between the mica sheet and the high-friction belt 32, the mica sheet can adhere firmly to the belt and is not easy to slip.

[0049] 3. Double-sided adhesive bonding

[0050] When the mica sheet moves to a certain position, its end contacts the roller 15. Because the mica sheet has a certain thickness, it will lift up the roller 15 and the U-shaped seat 14.

[0051] The rise of the U-shaped seat 14 causes the lever 13 to rotate along the pivot 12, which in turn drives the drive rod 17 to press down the slide plate 8. At this time, the spring 9 is further compressed, providing elastic force for subsequent reset.

[0052] As the slide plate 8 descends, the double-sided tape dispensing device 10 also descends. When the double-sided tape on the double-sided tape roll 21 passes through the inclined section 23 and the horizontal section 24, due to the connection between the blower 26 and the air extraction hole 25 through the air pipe, the double-sided tape is tightly adsorbed onto the inclined section 23 and the horizontal section 24.

[0053] Because one side of the double-sided adhesive is blocked by the connecting plate 19, precise positioning of the double-sided adhesive is achieved. When one side of the double-sided adhesive on the horizontal part 24 contacts one end of the mica sheet, the double-sided adhesive is adhered to the mica sheet.

[0054] IV. Double-sided tape cutting and repositioning

[0055] As the low-friction belt 33 and the high-friction belt 32 continue to convey the material, the double-sided adhesive is automatically fed from the double-sided adhesive roll 21 and adhered to the mica sheet.

[0056] After the roller 15 separates from the mica sheet, the cutting cylinder 27 starts, driving the laser cutting head 28 to cut the double-sided tape.

[0057] Due to the presence of lever 13 and spring 9, after cutting is completed, roller 15 and double-sided tape feeding device 10 will return to their original positions under the elastic force of spring 9, preparing for the next bonding operation.

[0058] V. Detailed Design Optimization

[0059] The gap between the horizontal part 24 and the bottom edge of the connecting plate 19 is slightly smaller than the thickness of the double-sided adhesive, ensuring that the double-sided adhesive can adhere tightly to the mica sheet.

[0060] The gap design between the inclined part 23 and the side edge of the connecting plate 19 avoids bending or damage to the double-sided adhesive during the transition process.

[0061] The tangential design between the cylindrical end of lever 13 and the top of U-shaped seat 14 reduces friction, allowing lever 13 to rotate more smoothly.

[0062] The U-shaped seat 14 ensures smooth and accurate up-and-down movement through the sliding connection of the slider 38 within the slide groove 37.
