Description

Technical Field

[0001] This invention belongs to the field of automotive battery manufacturing technology, specifically relating to a bonding equipment and process for automotive battery mica plates. Background Technology

[0002] Automotive battery mica plates are high-performance insulating composite materials, mainly made of natural or synthetic mica combined with silicone resin, glass fiber and other materials. They have good insulation properties, high temperature resistance and heat insulation and flame retardant capabilities, and are the core structure that plays a safety protection role in the power batteries of new energy vehicles.

[0003] In battery production, mica sheets play crucial roles in battery modules and packs, providing electrical insulation, fire protection, heat insulation, and structural protection. However, due to the low surface energy and poor cohesion of mica sheets, conventional adhesive tapes are difficult to apply effectively, often resulting in issues such as reverse release and residual adhesive after film removal, which affects efficiency. Therefore, it is necessary to bond thin film tapes (such as aluminum-plastic film tapes) onto mica sheets. The main purpose is to provide electrical insulation, fire protection, heat insulation, and structural protection while ensuring reliable bonding and production efficiency.

[0004] In the existing technology, during the bonding process of the film tape, due to the lack of a matching positioning structure, the film tape is easily misaligned, pulled, and subjected to uneven force during the cutting process, especially when cutting film tapes made of multiple layers of composite materials such as aluminum-plastic film. This can lead to problems such as burrs and tearing of the film tape at the cut site, affecting the product's appearance and performance. Summary of the Invention

[0005] The purpose of this invention is to provide a bonding device and process for mica sheets used in automotive batteries, which solves the technical problems in related technologies where the lack of a matching positioning structure leads to issues such as film strip displacement, stringing, and uneven stress during the cutting process, resulting in burrs and tears at the cut edges of the film strip.

[0006] According to one aspect, at least one embodiment of the present invention provides a bonding apparatus for mica panels used in automotive batteries, comprising an equipment frame, on which a lifting frame is mounted via a three-dimensional adjustment device, the three-dimensional adjustment device comprising a lateral adjustment unit, a longitudinal adjustment unit, and a height adjustment unit, wherein the lifting frame is mounted at the bottom of the height adjustment unit, and further comprising: A rotating frame is rotatably mounted on the bottom of the hoisting frame, and a swing frame is rotatably mounted on the bottom of the rotating frame; The mounting frame is fixedly mounted on the swing frame, and a flattening roller is mounted at the end of the mounting frame; A film cutting assembly is installed inside the mounting frame for cutting the film after lamination is completed.

[0010] Furthermore, several positioning posts are evenly spaced on both the front and rear sides of the positioning groove. The positioning posts are fixedly installed on the positioning frame, and the top of the positioning post is flush with the top of the positioning groove. When it is necessary to fix the position of the film, the positioning frame is moved so that the top of the positioning post abuts against the film, and the other side of the film is close to the bottom side of the mounting frame.

[0011] To prevent the film from adhering to the film positioning assembly during the film fixing process, the negative pressure positioning structure includes: A negative pressure cavity is provided at the bottom of the mounting frame; The mounting frame has several negative pressure holes at its bottom, which are connected to the negative pressure cavity. A connector is mounted on the mounting frame and communicates with the negative pressure cavity.

[0012] To move the cut film to the bonding position, the feeding assembly includes: A sliding frame, which is slidably mounted on the side of the swing frame; The fourth driving component is installed on the side of the swing frame, and the output end of the fourth driving component is fixedly connected to the sliding frame; A material-fixing rack is installed at the bottom of the sliding frame via an adjusting part.

[0029] Example 1, as Figures 1 to 12The diagram illustrates an adhesive device for automotive battery mica panels according to an embodiment of the present invention. It includes a frame 1, on which a lifting frame 3 is mounted via a three-dimensional adjustment device 2. The three-dimensional adjustment device 2 comprises a lateral adjustment unit 201, a longitudinal adjustment unit 202, and a height adjustment unit 203. The lifting frame 3 is mounted at the bottom of the height adjustment unit 203. The device also includes a rotating frame 4, a mounting frame 6, a film cutting assembly, a film positioning assembly, and a feeding assembly. The rotating frame 4 is rotatably mounted at the bottom of the lifting frame 3. A swing frame 5 is rotatably mounted at the bottom of the rotating frame 4. The mounting frame 6 is fixedly mounted on the swing frame 5. A flattening roller 7 is mounted at the end of the mounting frame 6. The device further includes a winding drum 8, a guide roller 9, and a first driving component 10. The winding drum 8 is rotatably mounted on the rotating frame 4, and the guide roller 9 is rotatably mounted on the swing frame 5. The first driving component 10... The first drive component 10 is rotatably mounted on the bottom of the rotating frame 4. The output end of the first drive component 10 is rotatably connected to the swing frame 5. A film cutting assembly is installed inside the mounting frame 6 for cutting the film after lamination. The film cutting assembly includes a groove 11, a slider 12, a guide rod 14, and a second drive component 15. The bottom of the mounting frame 6 has a groove 11. The slider 12 is slidably mounted inside the mounting frame 6. A cutting blade 13 is mounted on the bottom of the slider 12 and is slidably disposed inside the groove 11. A guide rod 14 is installed inside the mounting frame 6. The axial direction of the guide rod 14 is parallel to the sliding direction of the slider 12. The guide rod 14 and the slider 12 slide together to ensure the stability of the slider 12 during movement. The second drive component 15 is fixedly mounted on the swing frame 5, and the output end of the second drive component 15 is fixedly connected to the slider 12.

[0030] Before bonding the film to the battery mica plate, the rolled film (the film can be an aluminum-plastic film roll with a single-sided adhesive layer) needs to be installed on the winding drum 8. The relative position of the film and the winding drum 8 is fixed by the matching limiting structure to prevent the axial movement of the roll. Then, the film strip head is manually or mechanically pulled along the preset path of the equipment so that the film strip head passes around the guide roller 9 in sequence, through the gap between the feeding plate 26 and the mounting frame 6 and the gap between the positioning column 19 and the mounting frame 6, until it is pulled to the working position.

[0031] During the process of bonding the battery mica plate with film, the battery mica plate is first moved to the bearing position on the equipment frame 1, and then the position of the battery mica plate is fixed. Then, the three-dimensional adjustment device 2 is turned on. The position of the hoisting frame 3 is adjusted by setting the horizontal adjustment unit 201 and the vertical adjustment unit 202. Then, the height of the hoisting frame 3 is adjusted by the height adjustment unit 203 until the installation frame 6 is moved to the working position. At this time, the first drive component 10 is turned on, and the output end of the first drive component 10 pushes out, thereby pushing the swing frame 5 to swing downward until the flattening roller 7 at the end of the installation frame 6 and the film strip on the flattening roller 7 contact the battery mica plate. At this time, the film can be bonded to the battery mica plate by setting the horizontal adjustment unit 201 and the vertical adjustment unit 202. Each time the bonding position needs to be adjusted or after bonding is completed, the first drive component 10 needs to be retracted to temporarily detach the flattening roller 7 and the film strip from the battery mica plate. Then the position of the film can be adjusted.

[0032] After each film tape is bonded, it needs to be cut. First, the film tape is pressed down by the feeding assembly, and then the film positioning assembly is activated to fix the position of the film. At this time, the second drive component 15 is activated, which pushes the slider 12 to move along the guide rod 14, thereby driving the cutting blade 13 to move smoothly in the groove 11 to complete the straight cutting of the film, ensuring that the cut is flat, without pulling or burrs. Then, the negative pressure positioning structure is activated to fix the film tape to the bottom of the mounting frame 6. Then, the film positioning assembly is reset to prevent the film positioning assembly from sticking to the adhesive surface of the film tape. When the film tape is separated from the film positioning assembly, the adhesive surface of the film tape head is attached to the feeding assembly, and the front end of the film tape head is located outside the feeding assembly. Then, the feeding assembly sends the film tape head to the working position until the flattening roller 7 presses the film tape onto the battery mica plate. Then, the negative pressure positioning structure is activated again to fix the film tape to the bottom of the mounting frame 6. Then, the feeding assembly is separated from the adhesive surface of the film tape.

[0033] A film positioning assembly is installed on the mounting frame 6 to fix the position of the film during film cutting. A negative pressure positioning structure is integrated at the bottom of the mounting frame 6 to fix the position of the film after cutting, so that the adhesive side of the film is detached from the film positioning assembly. The film positioning assembly includes a positioning frame 16 and a third drive component 18. The positioning frame 16 is slidably mounted on the mounting frame 6. The bottom of the positioning frame 16 has a positioning groove 17, which corresponds to the sliding groove 11. The third drive component 18 is mounted on the mounting frame 6, and the output end of the third drive component 18 is fixedly connected to the positioning frame 16. Several positioning posts 19 are evenly spaced on both the front and rear sides of the positioning groove 17. The positioning posts 19 are fixedly mounted on the positioning frame 16, and the top of the positioning posts 19 is flush with the top of the positioning groove 17. When it is necessary to fix the position of the film, the positioning frame 16 moves so that the top of the positioning post 19 abuts against the film, and the other side of the film is close to the bottom side of the mounting frame 6.

[0034] When cutting the film strip, its position needs to be fixed. At this time, the third drive unit 18 is activated, which pushes the positioning frame 16 to move until the top of the positioning frame 16 and the internal positioning post 19 contacts the film strip. Figure 9 , Figure 10 As shown, when the positioning post 19 and the positioning frame 16 come into contact with the film tape, the positioning groove 17 is located at the bottom of the slide groove 11, and the free end of the cutting blade 13 is located in the positioning groove 17, which facilitates the cutting of the film tape and reduces the occurrence of tearing at the edge of the film tape. When it is necessary to move the positioning frame 16 back to its original position, the negative pressure positioning structure is activated to fix the film tape at the bottom of the mounting frame, so that the positioning frame 16 and the positioning post 19 can be smoothly separated from the adhesive surface of the film tape, which facilitates the smooth lamination process.

[0035] It should be added that the top of the positioning post 19 can be polished or coated with an anti-stick coating. Although it cannot completely prevent adhesion to the adhesive surface, it can make the film strip easier to detach.

[0036] The negative pressure positioning structure includes a negative pressure cavity 20, a negative pressure hole 21, and a connector 22. The bottom of the mounting frame 6 is provided with a negative pressure cavity 20 and several negative pressure holes 21 are opened at the bottom of the mounting frame 6. The negative pressure holes 21 are connected to the negative pressure cavity 20. The connector 22 is installed on the mounting frame 6 and is connected to the negative pressure cavity 20. Before use, the working end of the negative pressure device needs to be connected to the connector 22.

[0037] When it is necessary to fix the film strip to the bottom of the mounting frame 6, the negative pressure device draws air from the negative pressure cavity 20 through the connector 22, thereby creating a negative pressure state around the negative pressure hole 21 through the setting of the negative pressure hole 21, and then fixing the position of the film strip through negative pressure, so that the positioning frame 16 and the positioning post 19 can be removed from the adhesive layer of the film strip after cutting.

[0038] A feeding assembly is installed on the swing frame 5. During the film cutting process, the feeding assembly contacts the adhesive surface of the film end. After the film is cut, the feeding assembly can move along the mounting frame 6 through the film positioning assembly, placing the film end at the bottom of the flattening roller 7. Under the action of the negative pressure positioning structure, the film is separated from the feeding assembly. The feeding assembly includes a sliding frame 23, a fourth drive member 24, a fixed frame 25, and a feeding plate 26. The sliding frame 23 is slidably installed on the side of the swing frame 5. The fourth drive member 24 is installed on the side of the swing frame 5. The output end of the fourth drive member 24 is fixedly connected to the sliding frame 23. The fixed frame 25 is installed at the bottom of the sliding frame 23 through an adjustment part. The adjustment part is used to adjust the relative distance between the fixed frame 25 and the mounting frame 6. The feeding plate 26 is installed on the fixed frame 25. The feeding plate 26 is located at the bottom of the mounting frame 6 with a gap.

[0039] Before cutting the film strip, first open the adjustment unit to adjust the position of the feeding plate 26 on the fixed frame 25 until the upper side of the feeding plate 26 abuts against the film strip. After the cutting is completed, when it is necessary to send the film strip head to the working position, first reset the positioning frame 16. At this time, the gap between the positioning frame 16 and the mounting frame 6 can accommodate the movement of the feeding plate 26. Then, activate the fourth drive component 24, which pushes the sliding frame 23 to move until the film strip head adhering to the feeding plate 26 is moved to the working position through the fixed frame 25 and the feeding plate 26. When the film strip head is pressed onto the battery mica plate by the flattening roller 7, the film strip is fixed to the bottom of the mounting frame 6 again by the setting of the negative pressure positioning structure. Adjust the setting of the adjustment unit to separate the feeding plate 26 from the film strip and retract the fourth drive component 24.

[0040] The adjustment unit includes a sliding cavity 27 and a fifth drive member 29. The sliding cavity 27 is provided inside the sliding frame 23. The adjustment frame 28 is slidably installed inside the sliding cavity 27. The adjustment frame 28 is fixedly connected to the material station 25. The fifth drive member 29 is installed inside the sliding frame 23. The output end of the fifth drive member 29 is fixedly connected to the adjustment frame 28.

[0041] When the feeding plate 26 needs to contact the film strip, the fifth drive component 29 is retracted, and the position of the adjusting frame 28 in the sliding cavity 27 can be adjusted until the feeding plate 26 contacts the adhesive surface of the film strip. When it is necessary to separate the film strip and the feeding plate 26 that are bonded together, the film strip is first fixed to the bottom of the mounting frame 6 by the negative pressure positioning structure, and then the fifth drive component 29 is activated to push the adjusting frame 28 to move in the sliding cavity 27 until the film strip is separated from the feeding plate 26.

[0042] It should be noted that when the adjusting frame 28 moves to the extreme position at the bottom of the sliding cavity 27, the bottom surface of the feeding plate 26 still does not contact the reset positioning frame 16, and there is no interference.

[0043] It should be added that electric cylinders are preferred for the first drive unit 10, the second drive unit 15, the third drive unit 18, the fourth drive unit 24, and the fifth drive unit 29.

[0044] It also includes a motor 30 and a transmission gear 31. The motor 30 is fixedly installed inside the hoisting frame 3. Two transmission gears 31 are rotatably installed inside the hoisting frame 3. The two transmission gears 31 mesh with each other. The output end of the motor 30 is fixedly connected to one of the transmission gears 31, and the other transmission gear 31 is fixedly connected to the rotating frame 4.

[0045] When it is necessary to adjust the direction of the adhesive film tape, the motor 30 can be turned on. Through the setting of two meshing transmission gears 31, the rotating frame 4 can be driven to rotate, thereby adjusting the angle position of the adhesive film. After the adjustment is completed, the motor 30 can be turned off and locked.

[0046] The working principle or usage process of this application is as follows: Before operation, the aluminum-plastic film roll with a single-sided adhesive layer is mounted on the winding drum 8 of the rotating frame 4. The roll is fixed by a limiting structure to prevent axial movement. Then, the aluminum-plastic film strip head is pulled along a preset path, passing around the guide roller 9 on the swing frame 5 and passing through the gap between the feeding plate 26 and the mounting frame 6, and the gap between the positioning post 19 and the mounting frame 6. The film strip head is pulled to the cutting position so that the adhesive surface of the film strip end is attached to the upper side of the feeding plate 26, completing the film loading preparation. Then, the battery mica board to be processed is placed on the equipment frame. 1. Secure the mica plate to the bearing position and then turn on the three-dimensional adjustment device 2. First, fine-tune the horizontal position of the hoisting frame 3 through the horizontal adjustment unit 201 and the vertical adjustment unit 202. Then, adjust the vertical height of the hoisting frame 3 through the height adjustment unit 203. Move the installation frame 6 and the end flattening roller 7 directly above the mica plate adhesive application operation. Then, start the first drive component 10 to drive the swing frame 5 to swing downward relative to the rotating frame 4 until the flattening roller 7 and the bottom film tape are in contact with the surface of the mica plate, and the operation can begin.

[0047] During the bonding of the film strip, the horizontal and vertical adjustment functions of the three-dimensional adjustment device 2 drive the mounting frame 6 and the flattening roller 7 to move at a uniform speed. The flattening roller 7 rolls the aluminum-plastic film strip to the surface of the battery mica plate smoothly, realizing continuous film coating. After the film coating of a single section of mica plate is completed, the film strip can be cut. First, the feeding plate 26 is driven to move upward by the adjustment part to press against the end of the film strip to achieve pre-positioning. Then, the third driving component 18 is activated to push the positioning frame 16 to slide towards the bottom of the mounting frame 6. The top of the positioning column 19 clamps and fixes the film strip to the bottom side of the mounting frame 6 to prevent the film strip from shifting or tearing during cutting. Then, the second drive unit 15 is activated to drive the slider 12 to slide linearly along the guide rod 14, which in turn drives the cutting blade 13 to move within the slide groove 11 and the positioning groove 17 until the film tape is cut. This ensures that the cut is flat, burr-free, and free from pulling. After the cutting is completed, the negative pressure device can be activated to extract air from the negative pressure cavity 20 through the connector 22, causing the negative pressure hole 21 to generate negative pressure adsorption force, which fixes the cut film tape to the bottom of the mounting frame 6. Then, the third drive unit 18 is controlled to reset, which causes the positioning frame 16 and the positioning post 19 to separate from the adhesive surface of the film tape, preventing the adhesive surface from sticking together and causing the film tape to get stuck on the positioning frame 16 and the positioning post 19.

[0048] After the positioning frame 16 is reset, the adhesive surface of the cut film strip head is still attached to the feeding plate 26. At this time, the negative pressure equipment is turned off first, and the fourth drive component 24 is started to push the sliding frame 23 to move horizontally along the swing frame 5, so that the feeding plate 26 passes through the gap after the positioning frame 16 is reset, and the film strip head is transported to the working position at the bottom of the flattening roller 7. After the flattening roller 7 presses the film strip head onto the surface of the next section of mica board, the negative pressure equipment is turned on again to fix the film strip by adsorption force. The fifth drive component 29 is started to push the adjustment frame 28 to slide, so that the feeding plate 26 is separated from the adhesive surface of the film strip. Then the fourth drive component 24 is retracted, and the sliding frame 23 and the feeding plate 26 are reset, waiting for the next round of operation.

[0049] Example 2: Based on a bonding device for automotive battery mica plates, this example 2 also proposes a bonding process for automotive battery mica plates, including the following steps: The first step is to install the film roll and battery mica plate. The aluminum-plastic film roll with a single-sided adhesive layer is installed on the winding drum 8 and fixed. The film belt head is pulled around the guide roller 9, through the gap between the feeding plate 26, the positioning column 19 and the mounting frame 6 to the working position. The mica plate to be processed is fixed in the bearing position of the equipment frame 1. The second step is to adjust the equipment position, turn on the three-dimensional adjustment device 2, adjust the horizontal position and vertical height of the hoisting frame 3, move the installation frame 6 and the flattening roller 7 to the mica board adhesive application station, start the first drive component 10 to drive the swing frame 5 to press down until the flattening roller 7 pushes the film strip to adhere to the surface of the mica board. The third step is film coating. The three-dimensional adjustment device 2 is used to move the installation frame 6 horizontally, and the aluminum-plastic film strip is smoothly bonded to the mica board by the pressure roller 7. The fourth step is film strip cutting. After the film coating is completed, the adjustment unit drives the feeding plate 26 to press against the film strip, the third driving component 18 pushes the positioning frame 16 to move down, and fixes the film strip through the positioning column 19. The second driving component 15 is turned on to drive the cutting knife 13 to complete the straight cutting. At the same time, the negative pressure positioning structure is turned on to adsorb the film strip, so that the positioning frame 16 does not stick to the film strip during the reset process. The fifth step is to reset the feeding mechanism. The fourth drive unit 24 drives the feeding plate 26 to send the film strip head to the bottom of the flattening roller 7. After pressing, the film strip is fixed by negative pressure again. The adjustment unit drives the feeding plate 26 to separate from the film strip. Then the feeding assembly is reset to complete the single bonding operation.
