Description

Technical Field

[0001] The invention relates to the field of double-sided adhesive tape for mica sheets, and in particular to a double-sided adhesive tape tape device for power battery mica. Background Art

[0002] At present, the traditional process of attaching double-sided tape to mica sheets usually involves precisely placing the mica sheets in a specific mold. Subsequently, the double-sided tape attaching device relies on fine movement in the three axes of X, Y and Z to achieve accurate attachment of the double-sided tape to the mica sheets. However, this operation method has a significant efficiency bottleneck: every time a group of mica sheets is attached with double-sided tape, the entire production line must be paused so that the operator can manually remove the completed mica sheets from the mold and replace them with new mica sheets to be attached with double-sided tape. This process is not only time-consuming and labor-intensive, but the frequent interruptions also seriously affect the overall production efficiency.

[0003] To complicate matters further, different sizes of mica sheets require their own matching molds, which significantly increases the complexity of production preparation. Whenever mica sheets of different sizes need to be processed, the corresponding molds must be replaced, which not only increases production costs but also limits the flexibility and adaptability of the production line. The mold replacement process also requires time and manpower, further reducing production efficiency and may introduce fitting accuracy issues caused by mold mismatch.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figures 1 to 5 A double-sided adhesive bonding device for power battery mica is mainly composed of a frame 1 as a main support structure. On the inner side of the frame 1, we carefully configure a conveying device 2 for stably and continuously conveying mica sheets.

[0024] The conveying device 2 is composed of a driving roller 29, a first driven roller 30 and a second driven roller 31, which are all firmly mounted on the frame 1 by means of a rotational connection. In particular, the first driven roller 30 is cleverly arranged between the driving roller 29 and the second driven roller 31 to form an efficient transmission chain. A motor 39 is also fixed to the frame 1, and its output end is closely 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, we use several parallel belts 32 with a high friction coefficient for transmission connection to ensure that the mica sheet can be firmly attached to the belt during the conveying process to avoid sliding. Between the driving roller 29 and the second driven roller 31, several parallel belts 33 with a low friction coefficient are used for transmission. This design allows the mica sheet to easily slide on the low friction belt 33 when the position needs to be adjusted, thereby improving the flexibility of operation.

[0025] In order to further optimize the conveying and laminating effect of the mica sheet, we symmetrically installed two sets of adjustment devices 34 on the frame 1. These adjustment devices 34 are cleverly set at a position away from the high friction belt 32 to avoid any interference with the normal conveying of the mica sheet. Each set of adjustment devices 34 includes an adjustment cylinder 35, and an adjustment plate 36 is fixed at its output end. 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 position of the mica sheet.

[0026] On the top of the frame 1, we fixed a vertical plate 3, and a position adjustment cylinder 4 was firmly installed on one side of the vertical plate 3. The output end of the position adjustment cylinder 4 is closely connected to the mounting plate 5, so that the mounting plate 5 can flexibly adjust its position according to actual needs, further improving the adaptability and flexibility of the bonding device. An ear plate 6 is fixed on one side of the mounting plate 5, and a fixing rod 7 is fixed on the top of the ear plate 6. A slide 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 slide plate 8 respectively, providing stable support and buffering for the slide plate 8, ensuring that the double-sided tape discharge device 10 can move up and down smoothly.

[0027] On the slide plate 8, we have carefully designed a double-sided adhesive tape discharge device 10. The device consists of a connecting plate 19, a discharge shaft 20, a double-sided adhesive roll 21, an air suction box 22, an inclined portion 23, and a horizontal portion 24. The connecting plate 19 is fixed to the slide plate 8, and the discharge shaft 20 is installed on one side of the connecting plate 19 to carry the double-sided adhesive roll 21. The air suction box 22 is fixed to the other side of the connecting plate 19, and its side and bottom are respectively provided with an inclined portion 23 and a horizontal portion 24, which are in close contact with the double-sided adhesive tape. The inclined portion 23 and the horizontal portion 24 are both provided with air suction holes 25, which are connected to the inside of the air suction box 22. With the help of the fan 26, the double-sided adhesive tape is firmly adsorbed on the inclined portion 23 and the horizontal portion 24, ensuring the stability and accuracy of the bonding process.

[0028] In order to realize automatic cutting of the double-sided adhesive tape, a double-sided adhesive tape cutting device 18 is provided on the mounting plate 5. The device is composed of a cutting cylinder 27 and a laser cutting head 28, which can quickly and accurately cut off the double-sided adhesive tape when needed, thereby improving the automation and efficiency of the entire laminating process.

[0029] In addition, we have also 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 tape. This design ensures that the double-sided tape can be smoothly discharged from the discharge shaft 20 and attached to the mica sheet. 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 tape, which avoids the problem of the double-sided tape being stuck or damaged due to the gap being too small. At the same time, the connection between the horizontal part 24 and the inclined part 23 adopts an arc transition design, which effectively avoids the double-sided tape from bending or being damaged during the transition process, thereby improving the bonding quality.

[0030] The driving device 11 includes a lever 13 hinged to the mounting plate 5 through 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 is in contact with the top of the U-shaped seat 14, and a roller 15 that cooperates with the mica sheet is rotatably connected to the inner side of the U-shaped seat 14, an arc-shaped hole 16 is provided on the mounting plate 5, a driving rod 17 is fixed to the end of the lever 13 away from the U-shaped seat 14, and the driving rod 17 passes through the arc-shaped hole 16 and contacts the top of the skateboard 8; a double-sided tape cutting device 18 is provided on the mounting plate 5.

[0031] One end of the lever 13 is designed to be cylindrical and tangent to the top of the U-shaped seat 14. This design greatly reduces friction and allows the lever 13 to rotate more smoothly. The U-shaped seat 14 is slidably connected to the slide groove 37 on the mounting plate 5 through the slider 38, ensuring the stability and accuracy of its up and down movement. In addition, we have also cleverly set the distance between the rotating shaft 12 and the U-shaped seat 14 to be smaller than the distance between the rotating shaft 12 and the driving rod 17. This design allows the double-sided adhesive discharge device 10 to move up and down a sufficient distance, thereby avoiding unnecessary contact or interference between the double-sided adhesive and the conveying device 2, ensuring the smooth progress of the bonding process.

[0032] The working principle of the power battery mica double-sided adhesive bonding device is as follows: 1. Start-up and transportation When the device is started, the motor 39 starts to work, and its output end drives the active roller 29 to rotate.

[0033] The rotation of the active roller 29 is transmitted to the first driven roller 30 via a high friction belt 32 , and is also transmitted to the second driven roller 31 via a low friction belt 33 .

[0034] The mica sheet to be pasted with double-sided adhesive is placed at one end of the conveying device 2. Since the friction coefficient of the surface of the low-friction belt 33 is small, the mica sheet can slide easily on its surface.

[0035] 2. Position adjustment and conveying Through the coordinated action of the two adjusting cylinders 35, the output ends thereof drive the adjusting plate 36 to press the edge of the mica sheet, thereby accurately adjusting the position of the mica sheet.

[0036] As the motor 39 continues to drive, the active 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 sheet together.

[0037] When the mica sheet moves onto the high friction belt 32 , the mica sheet can be firmly attached to the belt and is not easy to slide due to the high friction coefficient of the surface and the relatively large contact area between the mica sheet and the high friction belt 32 .

[0038] 3. Double-sided tape bonding When the mica sheet moves to a certain position, its end contacts with roller 15. Because the mica sheet has a certain thickness, it will lift up roller 15 and U-shaped seat 14.

[0039] The rising of the U-shaped seat 14 causes the lever 13 to rotate along the rotating shaft 12, thereby driving the driving rod 17 to press down the slide plate 8. At this time, the spring 9 is further compressed, providing elastic force for subsequent resetting.

[0040] As the slide plate 8 descends, the double-sided adhesive unloading device 10 also descends. When the double-sided adhesive on the double-sided adhesive roll 21 passes through the inclined portion 23 and the horizontal portion 24, the double-sided adhesive is tightly adsorbed on the inclined portion 23 and the horizontal portion 24 due to the communication between the fan 26 and the air extraction hole 25 through the air pipe.

[0041] Since one side of the double-sided adhesive tape is blocked by the connecting plate 19, accurate positioning of the double-sided adhesive tape is achieved. When one side adhesive surface of the double-sided adhesive tape on the horizontal portion 24 contacts one end of the mica sheet, the double-sided adhesive tape is pasted on the mica sheet.

[0042] 4. Double-sided tape cutting and resetting As the low-friction belt 33 and the high-friction belt 32 continue to transmit, the double-sided adhesive tape is automatically unloaded from the double-sided adhesive roll 21 and pasted on the mica sheet.

[0043] When the roller 15 is separated from the mica sheet, the cutting cylinder 27 is started to drive the laser cutting head 28 to cut the double-sided adhesive tape.

[0044] Due to the existence of the lever 13 and the spring 9, when the cutting is completed, the roller 15 and the double-sided tape discharge device 10 will return to their original positions under the elastic force of the spring 9, ready for the next laminating operation.

[0045] 5. Detailed design optimization The gap between the horizontal portion 24 and the bottom edge of the connecting plate 19 is slightly smaller than the thickness of the double-sided adhesive tape, thereby ensuring that the double-sided adhesive tape can be tightly attached to the mica sheet.

[0046] The gap design between the inclined portion 23 and the side edge of the connecting plate 19 prevents the double-sided adhesive tape from being bent or damaged during the transition process.

[0047] The tangent design between the cylindrical end of the lever 13 and the top of the U-shaped seat 14 reduces the friction force, so that the lever 13 can rotate more smoothly.

[0048] The U-shaped seat 14 is connected by the sliding block 38 in the slide groove 37 to ensure the stability and accuracy of its up and down movement.
