Description

Technical Field

[0001] This application relates to the field of automatic film application technology, and in particular to a film application device. Background Technology

[0002] In existing production lines, PI film (Polyimide Film) is typically applied to products using laminating equipment or manually. PI film is a high-performance insulating material with excellent high-temperature resistance, mechanical properties, and electrical properties. However, using existing laminating equipment results in poor laminating precision, leading to at least 60mm of waste film per product, resulting in a high waste rate and failing to meet energy-saving requirements. While manual laminating offers higher precision, it carries a higher risk of film damage and can cause wrinkles and air bubbles. Safety hazards also exist during film cutting, further contributing to high labor costs and low production efficiency. Therefore, reducing the waste film rate while simultaneously lowering labor costs and improving production efficiency is a pressing technical challenge. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a film-applying device that reduces waste film rate, while simultaneously reducing labor costs and improving production efficiency.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] In a first aspect, embodiments of this application provide a film application device, including:

[0006] The loading and unloading mechanism includes a loading roller and a unloading roller. The loading roller is used to provide film, and the unloading roller is disposed above the loading roller and is used to wind up waste film.

[0007] A film widening mechanism includes a frame, a first gripper assembly, a second gripper assembly, and a film pressing assembly. The frame is disposed beside the feeding roller. The first gripper assembly is disposed on the side of the frame away from the feeding roller. The second gripper assembly is disposed on the side of the frame close to the feeding roller. The film pressing assembly is disposed above the first gripper assembly. The frame is provided with a driving mechanism for moving the first gripper assembly and the film pressing assembly horizontally toward or away from the second gripper assembly. The second gripper assembly is used to fix the film for the first gripper assembly to grip. The first gripper assembly is used to grip the film and pull the film toward the side of the frame away from the feeding roller. The film pressing assembly is used to press the film tightly onto the product surface.

[0008] A transfer mechanism is provided on the side of the frame parallel to the moving direction of the first gripper assembly. The transfer mechanism includes an X-axis module, a Y-axis module, and a Z-axis module. The Y-axis module is connected to the drive end of the X-axis module, and the Z-axis module is connected to the drive end of the Y-axis module.

[0009] A film cutting assembly, comprising a rotating module and a cutting blade, wherein the rotating module is connected to the drive end of the Z-axis module, and the cutting blade is connected to the drive end of the rotating module, and the rotating module is used to drive the cutting blade to rotate and change its cutting direction.

[0010] The film-applying device according to an embodiment of the first aspect of this application has at least the following beneficial effects: The feeding roller is controlled to convey the PI film to the second gripper assembly, and the unloading roller is controlled to wind up the release film. At this time, the PI film and the release film are separated. The second gripper assembly is controlled to clamp the PI film to fix it, and then the first gripper assembly is controlled to move horizontally toward the second gripper assembly via a drive mechanism. When the first gripper assembly moves to the second gripper assembly, it clamps the PI film. The second gripper assembly is controlled to release it, and then the first gripper assembly is controlled to move horizontally away from the second gripper assembly via a drive mechanism. When the first gripper assembly pulls the film to a preset film-applying position, the first gripper assembly stops moving horizontally via a drive mechanism, and then it is controlled to release it. The PI film is pressed tightly onto the product surface by the film-pressing assembly. After the PI film is pressed tightly onto the product surface, the film-cutting blade is controlled to cut the PI film along the product edge by the X-axis module, Y-axis module, Z-axis module, and rotary module. Compared with existing technologies, this application precisely controls the length of the PI film pulled out through the first and second gripper assemblies and performs a straightening and widening process, thereby reducing the waste film rate.

[0048] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0049] Reference Figure 1 , 2As shown in Figures 7, 8, and 9, the film application equipment includes a loading and unloading mechanism 100, a film spreading mechanism 200, a transfer mechanism 300, and a film cutting assembly 400. The loading and unloading mechanism 100 includes a loading roller 110 and a unloading roller 120. The loading roller 110 is used to provide film, and the unloading roller 120 is disposed above the loading roller 110 and is used to wind up waste film. The widening film mechanism 200 includes a frame 210, a first gripper assembly 220, a second gripper assembly 230, and a film pressing assembly 240. The frame 210 is disposed beside the loading roller 110. The first gripper assembly 220 is disposed on the side of the frame 210 away from the loading roller 110. The second gripper assembly 230 is disposed on the side of the frame 210 close to the loading roller 110. The film pressing assembly 240 is disposed above the first gripper assembly 220. The frame 210 is provided with a drive mechanism 250, which is used to move the first gripper assembly 220 and the film pressing assembly 240 horizontally toward or away from the second gripper assembly 230. The component 230 is used to fix the film for gripping by the first gripper assembly 220. The first gripper assembly 220 is used to grip the film and pull it toward the side of the frame 210 away from the feeding roller 110. The film pressing assembly 240 is used to press the film tightly onto the product surface. The transfer mechanism 300 is disposed on the side of the frame 210 parallel to the moving direction of the first gripper assembly 220. The transfer mechanism 300 includes an X-axis module 310, a Y-axis module 320, and a Z-axis module 330. The Y-axis module 320 is connected to the drive end of the X-axis module 310, and the Z-axis module 330 is connected to the drive end of the Y-axis module 320. The film cutting assembly 400 includes a rotating module 410 and a film cutting blade 420. The rotating module 410 is connected to the drive end of the Z-axis module 330, and the film cutting blade 420 is connected to the drive end of the rotating module 410. The rotating module 410 is used to drive the film cutting blade 420 to rotate and change its cutting direction.

[0050] In the above embodiment, the feeding roller 110 is controlled to transport the PI film to the second gripper assembly 230, and the unloading roller 120 is controlled to wind up the release film. At this time, the PI film and the release film are separated. The second gripper assembly 230 is controlled to clamp the PI film to fix it, and then the drive mechanism 250 controls the first gripper assembly 220 to move horizontally toward the second gripper assembly 230. When the first gripper assembly 220 moves to the second gripper assembly 230, it clamps the PI film. The second gripper assembly 230 is controlled to release it. Then, the drive mechanism 250 is controlled to move the first gripper assembly 220 horizontally away from the second gripper assembly 230. When the first gripper assembly 220 pulls the film to the preset film application position, the drive mechanism 250 is controlled to stop the first gripper assembly 223 from moving horizontally, and then the first gripper assembly 223 is controlled to release it. By controlling the film pressing assembly 240 to press the PI film tightly onto the product surface, and then controlling the X-axis module 310, Y-axis module 320, Z-axis module 330, and rotation module 410, the film cutting blade 420 cuts the PI film along the product edge. Compared with the prior art, this application precisely controls the length of the PI film pulled out through the first gripper assembly 220 and the second gripper assembly 230, and performs straightening and widening treatment on it, reducing the waste film rate. At the same time, it realizes fully automated film application and cutting, reducing labor costs and improving production efficiency.

[0051] Understandably, referring to Figure 9 , 10As shown, the drive mechanism 250 includes a first drive member 251, a first transmission member 252, a first sliding member group 253, a second drive member 254, a second transmission member 255, and a second sliding member group 256. The first drive member 251 is connected to the first transmission member 252, the first sliding member group 253 is connected to the first transmission member 252, and the first sliding member group 253 is connected to the first gripper assembly 220. The first drive member 251 is used to drive the first sliding member group 253 to move through the first transmission member 252, thereby driving the first gripper assembly 220 to move. The second drive member 254 is connected to the second transmission member 255, the second sliding member group 256 is connected to the second transmission member 255, and the second sliding member group 256 is connected to the second gripper assembly 230. The second drive member 254 is used to drive the second sliding member group 256 to move through the second transmission member 255, thereby driving the second gripper assembly 230 to move. The first driving component 251, the first transmission component 252, and the first sliding component group 253 cooperate to allow the first gripper assembly 220 to move horizontally toward or away from the second gripper assembly 230. The second driving component 254, the second transmission component 255, and the second sliding component group 256 cooperate to allow the second clamping assembly to move horizontally toward or away from the first gripper assembly 220. Therefore, the first gripper assembly 220 and the second gripper assembly 230 can straighten the PI film and control the length of the pulled-out PI film, thereby reducing the waste film rate and the probability of wrinkles and bubbles appearing after film application.

[0052] For example, such as Figure 9 , 10As shown, the first driving component 251 is a first motor, the second driving component 254 is a second motor, the first transmission component 252 is a first transmission rod, a first gear set, and a first track, the second transmission component 255 is a first transmission rod, a second gear, and a second track, the first sliding component group 253 includes two first sliding components, which are distributed on both sides of the first end of the frame 210, and each of the two first sliding components has a first sliding block on the side away from the frame 210, and the first sliding block is connected to the first track, the second sliding component group 256 includes two second sliding components, which are distributed on both sides of the second end of the frame 210, and each of the two second sliding components has a second sliding block on the side away from the frame 210, and the second sliding block is connected to the second track, the frame 210 has guide rails on both inner sides, the two first sliding components have a first slider matching the guide rail on the side closer to the inner side of the frame 210, and the two second sliding components have a second slider matching the guide rail on the side closer to the inner side of the frame 210. By activating the first and second motors, the first and second transmission rods rotate in a preset direction. This rotation causes the first and second gear sets to rotate. The rotation of the first and second gear sets causes the first and second tracks to move. This movement of the first and second tracks causes the first and second sliding blocks to move, which in turn causes the first and second sliding members to move along the guide rail. Because the first sliding member is connected to the first gripper assembly 220 and the second sliding member is connected to the second gripper assembly 230, the first gripper assembly 220 can move horizontally toward or away from the second gripper assembly 230, and the second gripper assembly 230 can move horizontally toward or away from the first gripper assembly 220.

[0053] Understandably, referring to Figure 3 As shown, the first gripper assembly 220 includes a first connecting plate 221, a first gripper cylinder 222, and a first gripper 223. The first connecting plate 221 is connected to the first sliding member assembly 253. The first gripper cylinder 222 is disposed on the lower surface of the first connecting plate 221. The first gripper 223 is disposed on the side of the first connecting plate 221 facing the second gripper assembly 230 and connected to the driving end of the first gripper cylinder 222. The first gripper cylinder 222 is used to control the opening and closing of the first gripper 223. By driving the first gripper cylinder 222, the first gripper 223 can be opened or closed, thereby enabling the first gripper 223 to grip and release the PI film.

[0054] The embodiments of this application do not limit the number of the first gripper cylinder 222 and the first gripper 223, and those skilled in the art can adjust them according to actual conditions. For example, Figure 3As shown, taking the setup of two first gripper cylinders 222 and two first grippers 223 as an example, the two first gripper cylinders 222 are symmetrically arranged on the lower surface of the first connecting plate 221, and the two first grippers 223 are symmetrically arranged on the side of the first connecting plate 221 facing the second gripper assembly 230. The two first gripper assemblies 220 are respectively connected to the drive ends of the two first gripper cylinders 222. Before film spreading, the two first grippers 223 are in the open state. During film spreading, the two first grippers 223 simultaneously move to the second gripper assembly 230, the second gripper assembly 230 releases the PI film, and then the two first gripper cylinders 222 drive the two first grippers 223 to close and clamp the PI film. Then, the two first grippers 223 move horizontally away from the second gripper assembly 230 to pull the PI film to the appropriate lamination position.

[0055] Understandably, referring to Figure 4 , 5 As shown, the second gripper assembly 230 includes a second connecting plate 231, a first lifting cylinder 232, a third connecting plate 233, a second gripper cylinder 234, and a second gripper 235. The second connecting plate 231 is connected to the second sliding component assembly 256. The first lifting cylinder 232 is disposed on the side of the second connecting plate 231 facing the first gripper 233. The third connecting plate 233 is connected to the drive end of the first lifting cylinder 232. The second gripper cylinder 234 is disposed on the side of the third connecting plate 233 facing the feeding roller 110. The second gripper 235 is connected to the drive end of the second gripper cylinder 234. The second gripper cylinder 234 is used to control the opening and closing of the second gripper 235. The first lifting cylinder 232 is used to control the movement of the third connecting plate 233. By driving the second gripper cylinder 234, the second gripper 235 can be opened or closed, so that the second gripper 235 can grip and release the PI film. When the first gripper 223 pulls the PI film to the film application position, the first lifting cylinder 232 is driven to move downward, and the film pressing assembly 240 presses the PI film onto the product.

[0056] The embodiments of this application do not limit the number of the second gripper cylinder 234 and the second gripper 235, and those skilled in the art can adjust them according to actual conditions. For example, Figure 4 , 5As shown, the first lifting cylinder 232 is positioned on the side of the second connecting plate 231 facing the first gripper 223. The third connecting plate 233 is connected to the drive end of the first lifting cylinder 232. Two second gripper cylinders 234 are symmetrically positioned on the side of the third connecting plate 233 facing the feeding roller 110. Two second grippers 235 are respectively connected to the drive ends of the two second gripper cylinders 234. When the feeding roller 110 conveys the PI film to the second gripper 235, the second gripper cylinder 234 causes the second gripper 235 to close and clamp the PI film. When the first gripper 223 moves to the second gripper 235 and clamps the PI film, the second gripper cylinder 234 causes the second gripper 235 to unfold and release the PI film. After the first gripper 223 clamps the PI film and moves to the film application position, the first lifting cylinder 232 causes the third connecting plate 233 to move downwards, simultaneously working with the film pressing assembly 240 to press the PI film firmly onto the upper surface of the product.

[0057] Understandably, referring to Figure 9 , 10 As shown, the drive mechanism 250 also includes a third drive member 257, a third transmission member 258, and a third sliding member group 259. The third drive member 257 is connected to the third transmission member 258, the third transmission member 258 is connected to the third sliding member group 259, and the third sliding member group 259 is connected to the film pressing assembly 240. The third drive member 257 is used to drive the third sliding member group 259 to move through the third transmission member 258, thereby driving the film pressing assembly 240 to move. The third drive member 257, the third transmission member 258, and the third sliding member group 259 cooperate with each other to allow the film pressing assembly 240 to move toward or away from the second gripper 235. When the first gripper 223 pulls the PI film to the film application position, the film pressing assembly 240 can reciprocate horizontally toward or away from the second gripper 235 to press the PI film tightly onto the product, reducing the probability of wrinkles and bubbles.

[0058] For example, such as Figure 9 , 10As shown, the third driving component 257 is a third motor, the third transmission component 258 is a third transmission rod, a third gear set, and a third track, and the third sliding component group 259 includes two third sliding components. The two third sliding components are distributed between the first and second sliding components and close to the first sliding component. Each of the two third sliding components has a first sliding block on the side away from the frame 210. The third sliding block is connected to the first track. Each of the two third sliding components has a third slider that matches the guide rail on the side closer to the inside of the frame 210. When the first clamp pulls the PI film to the appropriate film-applying position, the third motor is started to rotate the third transmission rod in a preset direction. The rotation of the third transmission rod causes the third gear set to rotate, which in turn causes the third track to move. The movement of the third track causes the two third sliding components to move, thereby causing the film-pressing assembly 240 to reciprocate toward or away from the second clamp 235. This allows the PI film to be repeatedly pressed tightly onto the product surface, reducing the probability of wrinkles and bubbles forming between the product surface and the PI film.

[0059] Understandably, referring to Figure 6 As shown, the film pressing assembly 240 includes a second lifting cylinder 241, a fourth connecting plate 242, a fifth connecting plate 243, and a coating roller 244. The fourth connecting plate 242 is connected to a third sliding component group 259. The second lifting cylinder 241 is located on the side of the fourth connecting plate 242 facing the first gripper 223. The fifth connecting plate 243 is connected to the drive end of the second lifting cylinder 241. The coating roller 244 is slidably connected to the fifth connecting plate 243. When the first gripper 223 pulls the PI film to the film-applying position, the second lifting cylinder 241 causes the coating roller 244 to move downwards and then reciprocate horizontally towards or away from the second gripper 235 to press the PI film firmly onto the product, reducing the probability of wrinkles and bubbles.

[0060] For example, such as Figure 6 As shown, the two ends of the fourth connecting plate 242 are respectively connected to two third sliding members. The second lifting cylinder 241 is located in the center of the side of the fourth connecting plate 242 facing the first gripper 223. The fifth connecting plate 243 is connected to the drive end of the second lifting cylinder 241. The two ends of the rubber-coated roller 244 can be slidably connected to the two ends of the fifth connecting plate 243. A spring and a slide rail are provided between the rubber-coated roller 244 and the fifth connecting plate 243.
