Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing technology, and in particular to a hot-pressing coating mechanism and a coating film processing device. Background Technology

[0002] In photovoltaic module manufacturing, to ensure electrical safety, insulating films are laid in the gaps between solar cells to isolate current paths and prevent leakage risks. As the demand for photoelectric conversion efficiency continues to increase, module manufacturers lay reflective films in the gaps between solar cells to improve the module's photoelectric conversion efficiency by reflecting leaked light. To meet the dual requirements of improving power generation efficiency and ensuring electrical safety, the synergistic use of reflective and insulating films has become a key technology in the production of high-end modules.

[0003] Existing reflective film and insulating film lamination mechanisms can laminate reflective film and insulating film together to form... Figure 10 (a) shows the composite film strip, but it is impossible to achieve intermittent lamination of the reflective film onto the insulating film, forming Figure 10 (b) shows a laminated film strip with gaps between the reflective films. Therefore, there is an urgent need to develop a lamination mechanism that can obtain a laminated film on an insulating film with reflective films intermittently laminated, in order to improve the production efficiency and product quality of photovoltaic modules and promote the advancement of photovoltaic module manufacturing technology. Utility Model Content

[0004] The purpose of this application is to provide a hot-pressing lamination mechanism and a lamination processing device to solve the technical problem that existing reflective film and insulating film pressing mechanisms cannot obtain a lamination film in which reflective film is intermittently laminated onto insulating film.

[0005] This application provides a hot-pressing coating mechanism, which includes a mounting frame and a first feeding assembly, a second feeding assembly, a heating assembly, a pressing assembly, and a first shearing assembly disposed on the mounting frame, wherein: The first feeding assembly is used to provide reflective film, and the second feeding assembly is used to provide insulating film; The mounting frame is provided with a first guide channel and a second guide channel. The pressing assembly includes a first pressure roller, a second pressure roller and a lifting drive source arranged vertically. The first pressure roller is installed on the driving end of the lifting drive source, and the lifting drive source drives the first pressure roller to move toward or away from the second pressure roller. The reflective film led out from the first feeding assembly and the insulating film led out from the second feeding assembly pass through the first guide channel and the second guide channel respectively under the pull of the traction force, and meet and press between the first pressure roller and the second pressure roller to form a composite film strip. The heating assembly includes an air blower for blowing hot air, the air blower being positioned in front of the pressing assembly, with the air outlet of the air blower facing the reflective film and / or insulating film. The first shearing assembly includes a first pair of scissors, a first shearing drive source, and a motion drive source. The first scissors are configured to move at least between an initial position located between the pressing assembly and the blowing head and a first cutting position located after the pressing assembly. The first shearing drive source is configured to drive the first scissors to open and close so that the reflective film can pass through and cut the reflective film. The first shearing drive source drives the first shears to open in the initial position to allow the reflective film to pass through. The motion drive source drives the first shears to move from the initial position along the reflective film and move through the open first pressure roller and second pressure roller to the first cutting position. The first shears close in the first cutting position and cut the reflective film.

[0006] During operation, the hot-pressing laminating mechanism involves a reflective film from the first feeding component passing sequentially through the first guide channel and the gap between the first and second pressure rollers. Similarly, an insulating film from the second feeding component passes sequentially through the second guide channel and the gap between the first and second pressure rollers. Before entering the first and second pressure rollers, the reflective and / or insulating films are heated to a sticky state by hot air from an air blower. This allows the reflective and insulating films to meet within the gap between the first and second pressure rollers and bond together under the pressure of the two rollers to form a laminated film strip. By hot-pressing the reflective and insulating films together, the reflective film application process and the insulating film application process can be performed simultaneously, achieving precise laying and efficient lamination of the two film materials. This improves the production efficiency and product quality of photovoltaic modules and promotes the advancement of photovoltaic module manufacturing technology. Heating either the reflective or insulating film to a sticky state, or heating both simultaneously, achieves the purpose of hot-pressing bonding. Meanwhile, the first shearing component can cut the reflective film at different positions and at different times to obtain a composite film strip on which the reflective film is intermittently laminated onto the insulating film.

[0007] As a further technical solution, the motion drive source includes a first drive source and a second drive source; The first driving source is configured to drive the first scissors to reciprocate along the width direction of the reflective film, so that the first scissors enter or exit the upper and lower sides of the reflective film along the width direction of the reflective film. The second drive source is configured to drive the first scissors to reciprocate between an initial position and a first cutting position, so that the first scissors can move from the initial position along the reflective film and through the open first and second pressure rollers to the first cutting position, and return from the first cutting position to the initial position.

[0008] By coordinating the first and second drive sources, the first shears can move independently in two directions: the first drive source allows the first shears to laterally enter or exit the upper and lower sides of the reflective film, thus completing the cutting preparation without interfering with normal film feeding; the second drive source drives the first shears to move along the reflective film conveying direction, enabling it to pass from the initial position between the opened first and second pressure rollers to reach the first cutting position. This step-by-step driving method ensures the accuracy and safety of the cutting action, avoids collisions with the pressure rollers or film belt, and improves the stability and reliability of the mechanism's operation.

[0009] As a further technical solution, the first pair of scissors is also configured to move to a second cutting position located after the first cutting position; The first shearing drive source is also configured to drive the first shears to open and close so that the insulating film can pass through and cut the insulating film; The first driving source is also configured to drive the first scissors to reciprocate along the width direction of the insulating film, so that the first scissors enter or exit the upper and lower sides of the insulating film along the width direction of the insulating film. The second drive source is also configured to drive the first scissors to reciprocate between an initial position and a second cutting position, so that the first scissors can cut the insulating film at the second cutting position.

[0010] By increasing the stroke of the second drive source along the length of the film strip, the first shears can not only cut the reflective film but also move to the second cutting position to cut the insulating film. This means that a single shearing assembly can complete the cutting of two types of film materials. This design simplifies the overall structure, reduces the number of parts, and lowers equipment costs and maintenance difficulty. Simultaneously, by sharing a single drive system, the coordination and synchronization accuracy of the movements are improved, allowing for precise matching of the cutting positions of different film materials and ensuring the processing quality of the laminated film strip.

[0011] As a further technical solution, the hot-pressing coating mechanism also includes a second shearing component; The second shearing assembly includes a second pair of scissors and a second shearing drive source. The second scissors are disposed after the pressing assembly, and the second shearing drive source is configured to drive the second scissors to open and close so that the insulating film can pass through and cut the insulating film.

[0012] The second shearing component allows for independent cutting of the insulating film. This independent second shear can complete the cutting of the insulating film without affecting the reflective film cutting action, greatly improving production efficiency. Furthermore, this modular design facilitates subsequent upgrades or adjustments; for example, when different cutting lengths or frequencies are required, only the parameters of the corresponding shearing component need to be adjusted.

[0013] As a further technical solution, the reflective film is located above the insulating film; The hot-pressing laminating mechanism also includes a first traction component, which is disposed in front of the first shearing component. The first traction component is used to pull the reflective film located in front of the first cutting position to move away from the reflective film located behind the first cutting position after the first shearing component cuts the reflective film at the first cutting position, so that there is a gap between the reflective film located in front of the first cutting position and the reflective film located behind the first cutting position. and / or; The hot-pressing laminating mechanism also includes a second traction component, which is disposed after the pressing component. The second traction component is used to pull the insulating film located after the first cutting position away from the pressing component after the first cutting component cuts the reflective film at the first cutting position, so that there is a gap between the reflective film located before the first cutting position and the reflective film located after the first cutting position.

[0014] After the reflective film is cut, the reflective film located before the first cutting position can be pulled backward by the first traction component, moving it away from the reflective film located after the first cutting position, thus creating a predetermined gap between the two reflective film segments after cutting. Alternatively, the insulating film located after the first cutting position can be pulled forward by the second traction component, moving it away from the pressing component, thus creating a predetermined gap between the two reflective film segments after cutting. By creating a gap between the two reflective film segments after cutting, the discontinuous distribution of the reflective film on the laminated film strip meets the design requirements, avoiding overlap or close proximity of adjacent reflective film segments.

[0015] As a further technical solution, the first traction component includes a third drive source, a fourth drive source, a pressure head, a connector, a bracket, a slide rail, and a slider mounted on the slide rail; The third drive source and the slide rail are respectively located on opposite sides of the mounting bracket. The slide rail and the first guide channel are located on the same side of the mounting bracket and are parallel. The first guide channel is covered by a cover plate, and the cover plate is provided with an elongated hole extending along the extension direction of the first guide channel. The bracket is connected to the slider, and the third drive source is set on the bracket; The third drive source is connected to the pressure head, and the pressure head corresponds to the elongated hole; the fourth drive source is connected to the bracket. The third drive source is configured to drive the pressure head to reciprocate toward and away from the elongated hole in order to extend into and out of the elongated hole. The fourth drive source is configured to drive the bracket to reciprocate along the extension direction of the slide rail, thereby driving the pressure head to reciprocate along the extension direction of the slide rail.

[0016] The first traction component, through the cooperation of the pressure head and the slide rail, can quickly pull the reflective film located in front of the first cutting position backward after the reflective film is cut, forming a preset gap. The parallel arrangement of the slide rail and the first guide channel ensures the stability of the traction direction, reduces the offset of the reflective film during the traction process, and improves the dimensional accuracy of the product. The third drive source and the slide rail are located on both sides of the mounting frame, ensuring the stability of the pressure head's movement and avoiding interference with other components. The elongated hole design on the cover plate not only provides a movement channel for the pressure head but also serves as a guide, ensuring that the pressure head always moves along the correct trajectory. This compact layout design improves space utilization while ensuring precise and controllable traction action.

[0017] As a further technical solution, the second traction assembly includes a fifth drive source, a sixth drive source, and a clamping component; The fifth drive source is configured to drive the clamping member to open and close in order to release and clamp the insulating film; The sixth drive source is configured to drive the clamping member to reciprocate in a set direction to pull the insulating film.

[0018] The second traction assembly employs a combination of clamping components and dual drive sources, which not only reliably clamps the insulating film but also precisely controls the traction distance. After the reflective film is cut, pulling the insulating film located behind the first cutting position forward creates a uniform gap between the cut reflective films. This design, independent of reflective film traction, allows for more flexible adjustment of the relative positions of the two film materials, adapting to the production needs of laminated film tapes of different specifications. Specifically, the clamping components of the second traction assembly are controlled by a fifth drive source, automatically adjusting the clamping force according to the thickness of the insulating film, ensuring reliable clamping while avoiding damage to the insulating film. The sixth drive source precisely controls the movement distance of the clamping components, ensuring consistent traction length each time, thus guaranteeing the uniformity of the reflective film gaps on the insulating film. This design is suitable for high-speed continuous production, improving production efficiency while maintaining quality.

[0019] This application provides a film processing apparatus, which includes a film belt support platform and a hot-pressing film coating mechanism as described above, disposed at at least one of the opposite ends of the film belt support platform.

[0020] A hot-pressing laminating mechanism can be installed at either end of the laminating film belt carrier platform, or at both ends. When the laminating film processing device adopts a layout with hot-pressing laminating mechanisms at both ends, the second traction components can be combined to form a double-headed traction mechanism, greatly improving production efficiency. When one end is undergoing material change or maintenance, the other end can continue production, reducing equipment downtime. The laminating film belt carrier platform ensures stable conveying of the laminating film belt, guaranteeing the continuity and stability of the entire production process.

[0021] As a further technical solution, the laminating film processing device also includes a seventh drive source and at least one pressure roller disposed on the laminating film belt support platform. The seventh drive source is configured to drive the pressure roller to rise and fall to avoid the second traction component and press down the laminating film belt.

[0022] The lifting function of the pressure roller is controlled by the seventh drive source. It rises to avoid interference when the second traction component moves, and lowers to press the laminated film belt when pressing is required. This avoids interference between the second traction mechanism and the pressure roller, while ensuring the flatness of the laminated film belt during transportation. The pressure of the pressure roller can be adjusted according to the characteristics of the film material, adapting to the production needs of laminated film belts made of different materials.

[0023] As a further technical solution, the laminating film processing device also includes an eighth drive source, which is configured to drive the pressure roller to reciprocate along the extension direction of the laminating film belt support platform.

[0024] The eighth drive source drives the pressure rollers to reciprocate along the extension direction of the laminating film belt support platform. This not only presses the laminating film belt tightly but also smooths it out, eliminating wrinkles or air bubbles. This dynamic pressing method further improves the bonding quality of the laminating film belt while simplifying the equipment structure, achieving multiple functions with the same set of pressure rollers.

[0033] The present application will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0034] The specific structure is as follows: Figures 1 to 9 As shown.

[0035] This embodiment provides a hot-pressing laminating mechanism 37, which includes a mounting frame 23 and a first feeding assembly 1, a second feeding assembly 2, a heating assembly 3, a pressing assembly 4, and a first shearing assembly 5 disposed on the mounting frame 23. The first feeding assembly 1 provides a reflective film 6, and the second feeding assembly 2 provides an insulating film 7. The mounting frame 23 is provided with a first guide channel 8 and a second guide channel 9. The pressing assembly 4 includes a first pressure roller 10 and a second pressure roller 11 disposed vertically, and a lifting drive source 12. The first pressure roller 10 is mounted on the driving end of the lifting drive source 12, which drives the first pressure roller 10 to move towards or away from the second pressure roller 11. The reflective film 6 led from the first feeding assembly 1 and the insulating film 7 led from the second feeding assembly 2 pass through the first guide channel 8 and the second guide channel 9 respectively under traction, and converge and press between the first pressure roller 10 and the second pressure roller 11. A laminated film strip is formed; the heating assembly 3 includes an air blower 13 for blowing hot air, the air blower 13 is disposed in front of the pressing assembly 4, and the air outlet on the air blower 13 faces the reflective film 6 and / or the insulating film 7; the first shearing assembly 5 includes a first scissors 14, a first shearing drive source 15 and a motion drive source, the first scissors 14 is configured to move at least between an initial position located between the pressing assembly 4 and the air blower 13 and a first cutting position located in the rear of the pressing assembly 4, the first shearing drive source 15 is configured to drive the first scissors 14 to open and close so that the reflective film 6 can pass through and cut the reflective film 6; the first shearing drive source 15 drives the first scissors 14 to open in the initial position so that the reflective film 6 can pass through, the motion drive source drives the first scissors 14 to move from the initial position along the reflective film 6 and through the open first pressure roller 10 and second pressure roller 11 to the first cutting position, the first scissors 14 closes in the first cutting position to cut the reflective film 6.

[0036] During operation, the hot-pressing coating mechanism 37 allows the reflective film 6, drawn from the first feeding component 1, to pass sequentially through the gap between the first guide channel 8 and the first pressure roller 10 and the second pressure roller 11. Similarly, the insulating film 7, drawn from the second feeding component 2, passes sequentially through the gap between the second guide channel 9 and the first pressure roller 10 and the second pressure roller 11. Before passing through the first pressure roller 10 and the second pressure roller 11, the reflective film 6 and / or the insulating film 7 are heated to adhesiveness by hot air blown from the air blower 13. This allows the reflective film 6 and the insulating film 7 to meet within the gap between the first pressure roller 10 and the second pressure roller 11 and bond together under the pressure of the two pressure rollers 35 to form a laminated film strip. By hot-pressing and bonding the reflective film 6 and the insulating film 7, the application processes of the reflective film 6 and the insulating film 7 can be performed simultaneously, achieving precise laying and efficient lamination of the two film materials. This improves the production efficiency and product quality of photovoltaic modules and promotes the advancement of photovoltaic module manufacturing technology. Heating either the reflective film 6 or the insulating film 7 to a sticky state, or heating both simultaneously to a sticky state, can achieve the purpose of hot-pressing and bonding the two. The first shearing drive source 15 drives the first scissors 14 to open in the initial position to allow the reflective film 6 to pass through. The motion drive source drives the first scissors 14 to move from the initial position along the reflective film 6 and pass between the opened first pressure roller 10 and second pressure roller 11 to the first cutting position. The first scissors 14 closes at the first cutting position and cuts the reflective film 6, thus achieving the cutting of the reflective film 6. The first shearing assembly 5 can cut the reflective film 6 at different positions and at different times to obtain... Figure 10 (b) shows the reflective film 6 intermittently laminated onto the insulating film 7.

[0037] It should be noted that, as Figure 2 As shown, the lifting drive source 12 drives the first pressure roller 10 away from the second pressure roller 11, which is equivalent to opening the first pressure roller 10 and the second pressure roller 11; as Figure 1 As shown, the lifting drive source 12 drives the first pressure roller 10 to move toward the second pressure roller 11, which is equivalent to closing the first pressure roller 10 and the second pressure roller 11.

[0038] In the optional technical solutions of this embodiment, such as Figure 5 As shown, the motion drive source includes a first drive source 16 and a second drive source 17; the first drive source 16 is configured to drive the first scissors 14 to reciprocate along the width direction of the reflective film 6, so that the first scissors 14 enters or exits the upper and lower sides of the reflective film 6 along the width direction of the reflective film 6; the second drive source 17 is configured to drive the first scissors 14 to reciprocate between the initial position and the first cutting position, so that the first scissors 14 can move along the reflective film 6 from the initial position and pass between the opened first pressure roller 10 and the second pressure roller 11 to the first cutting position, and return from the first cutting position to the initial position.

[0039] In this embodiment, the motion drive source, through the cooperation of the first drive source 16 and the second drive source 17, enables the independent movement of the first scissors 14 in two directions: the first drive source 16 allows the first scissors 14 to laterally enter or exit the upper and lower sides of the reflective film 6, thereby completing the cutting preparation without interfering with normal film feeding; the second drive source 17 drives the first scissors 14 to move along the conveying direction of the reflective film 6, realizing the movement from the initial position through the open first pressure roller 10 and second pressure roller 11 to the first cutting position. This step-by-step driving method ensures the accuracy and safety of the cutting action, avoids collisions with the pressure roller 35 or the film belt, and improves the stability and reliability of the mechanism operation.

[0040] In this embodiment, the motion drive source drives the first scissors 14 in two ways. One way is: in the initial position, the first drive source 16 drives the first scissors 14 to laterally enter the upper and lower sides of the reflective film 6 to complete the cutting preparation. Then, the second drive source 17 drives the first scissors 14 to move along the conveying direction of the reflective film 6 to reach the first cutting position to complete the cutting. After the cutting is completed, the second drive source 17 and the first drive source 16 sequentially drive the first scissors 14 back to the initial position along the original path. The other way is: in the initial position, the first drive source 16 drives the first scissors 14 to laterally enter the upper and lower sides of the reflective film 6 to complete the cutting preparation. Then, the second drive source 17 drives the first scissors 14 to move along the conveying direction of the reflective film 6 to reach the first cutting position to complete the cutting. After the cutting is completed, the first drive source 16 drives the first scissors 14 to laterally exit the upper and lower sides of the reflective film 6. Then, the second drive source 17 drives the first scissors 14 to return to the initial position in the opposite direction of the conveying direction of the reflective film 6.

[0041] In the optional technical solution of this embodiment, the first scissors 14 is further configured to move to a second cutting position located after the first cutting position, and the first cutting drive source 15 is further configured to drive the first scissors 14 to open and close so that the insulating film 7 can pass through and cut the insulating film 7; the first drive source 16 is further configured to drive the first scissors 14 to move back and forth along the width direction of the insulating film 7 so that the first scissors 14 enters or exits the upper and lower sides of the insulating film 7 along the width direction of the insulating film 7; the second drive source 17 is further configured to drive the first scissors 14 to move back and forth between the initial position and the second cutting position so that the first scissors 14 can cut the insulating film 7 at the second cutting position.

[0042] In this embodiment, by increasing the stroke of the second drive source 17 along the length of the film strip, the first shears 14 can not only cut the reflective film 6, but also move to the second cutting position to cut the insulating film 7. This means that a single shearing component can complete the cutting of two types of film materials. This design simplifies the overall structure, reduces the number of parts, and lowers equipment costs and maintenance difficulty. At the same time, by sharing a single drive system, the coordination and synchronization accuracy of the movements are improved, enabling precise matching of the cutting positions of different film materials and ensuring the processing quality of the laminated film strip.

[0043] In the optional technical solutions of this embodiment, such as Figure 1 As shown, the hot-pressing coating mechanism 37 also includes a second shearing assembly 18; the second shearing assembly 18 includes a second shear 19 and a second shearing drive source 20. The second shear 19 is disposed after the pressing assembly 4, and the second shearing drive source 20 is configured to drive the second shear 19 to open and close so that the insulating film 7 can pass through and cut the insulating film 7.

[0044] In this embodiment, the insulating film 7 can be cut independently by the second shearing component 18. The independent second shears 19 can complete the cutting of the insulating film 7 without affecting the cutting action of the reflective film 6, greatly improving production efficiency. In addition, this modular design also facilitates subsequent upgrades or adjustments. For example, when different cutting lengths or frequencies are required, only the parameters of the corresponding shearing components need to be adjusted.

[0045] In the optional technical solutions of this embodiment, such as Figure 1 As shown, the reflective film 6 is located above the insulating film 7; as Figures 7 to 9 As shown, the hot-pressing laminating mechanism 37 also includes a first traction component 21. The first traction component 21 is disposed in front of the first shearing component 5. After the first shearing component 5 cuts the reflective film 6 at the first cutting position, the first traction component 21 is used to pull the reflective film 6 located in front of the first cutting position in a direction away from the reflective film 6 located behind the first cutting position (i.e., to retract the reflective film connected to the first feeding component backward), so that there is a gap between the reflective film 6 located in front of the first cutting position and the reflective film 6 located behind the first cutting position, thus producing a result as shown in the figure. Figure 10 (b) The laminating film tape shown; and / or; the hot-pressing laminating mechanism 37 further includes a second traction assembly 22, which is disposed after the pressing assembly 4. The second traction assembly 22 is used to pull the insulating film 7 located after the first cutting position to move away from the pressing assembly 4 after the first cutting assembly 5 cuts the reflective film 6 at the first cutting position, so that there is a gap between the reflective film 6 located before the first cutting position and the reflective film 6 located after the first cutting position, thereby producing the desired effect. Figure 10 (b) shows the composite film strip.

[0046] In this embodiment, after the reflective film 6 is cut, the first traction component 21 can pull the reflective film 6 located before the first cutting position backward, so that the reflective film 6 located before the first cutting position is away from the reflective film 6 located after the first cutting position, thereby creating a preset gap between the two reflective film segments 6 after cutting. Alternatively, the second traction component 22 can pull the insulating film 7 located after the first cutting position forward, so that the insulating film 7 located after the first cutting position is away from the pressing component 4, thereby creating a preset gap between the two reflective film segments 6 after cutting. By creating a gap between the two reflective film segments 6 after cutting, the discontinuous distribution of the reflective film 6 on the laminated film strip meets the design requirements, avoiding the overlap or close proximity of adjacent reflective film segments 6.

[0047] Specifically, such as Figure 5 and Figure 6 As shown, the first traction assembly 21 includes a third drive source, a fourth drive source 24, a pressure head 25, a connector 26, a bracket 27, a slide rail 28, and a slider 29 mounted on the slide rail 28. The third drive source and the slide rail 28 are respectively located on opposite sides of the mounting frame 23. The slide rail 28 and the first guide channel 8 are located on the same side of the mounting frame 23 and are parallel. The first guide channel 8 is covered by a cover plate 30, and the cover plate 30 is provided with an elongated hole 31 extending along the extension direction of the first guide channel 8. The bracket 27 A third drive source is connected to the slider 29 and mounted on the bracket 27. The third drive source is driven by the pressure head 25, which corresponds to the elongated hole 31. A fourth drive source 24 is driven by the bracket 27. The third drive source is configured to drive the pressure head 25 to reciprocate towards and away from the elongated hole 31, extending into and exiting the hole. The fourth drive source 24 is configured to drive the bracket 27 to reciprocate along the extension direction of the slide rail 28, thereby driving the pressure head 25 to reciprocate along the extension direction of the slide rail 28. The first traction assembly 21, through the cooperation of the pressure head 25 and the slide rail 28, can quickly pull the reflective film 6 located before the first cutting position backward after it is cut, forming a preset gap. The parallel arrangement of the slide rail 28 and the first guide channel 8 ensures the stability of the traction direction, reduces the offset of the reflective film 6 during the traction process, and improves the dimensional accuracy of the product.

[0048] The third drive source and slide rail 28 are located on both sides of the mounting bracket 23, ensuring the stability of the pressure head 25's movement and avoiding interference with other components. The elongated hole 31 on the cover plate 30 not only provides a movement channel for the pressure head 25 but also serves as a guide, ensuring that the pressure head 25 always moves along the correct trajectory. This compact layout design improves space utilization while ensuring precise and controllable traction movements.

[0049] Specifically, such as Figure 7As shown, the second traction assembly 22 includes a fifth drive source 32, a sixth drive source, and a clamping member 33; the fifth drive source 32 is configured to drive the clamping member 33 to open and close to release and clamp the insulating film 7; the sixth drive source is configured to drive the clamping member 33 to reciprocate along a set direction to traction the insulating film 7.

[0050] The second traction assembly 22 employs a combination of clamping member 33 and dual drive sources, which not only reliably clamps the insulating film 7 but also precisely controls the traction distance. After the reflective film 6 is cut, by pulling the insulating film 7 located behind the first cutting position forward, a uniform gap can be formed between the cut reflective films 6. This design, independent of the traction of the reflective film 6, allows for more flexible adjustment of the relative positions of the two film materials, adapting to the production needs of laminated film tapes of different specifications.

[0051] The clamping component 33 of the second traction assembly 22 is controlled by a fifth drive source 32 to open and close, automatically adjusting the clamping force according to the thickness of the insulating film 7. This ensures reliable clamping while preventing damage to the insulating film 7. A sixth drive source precisely controls the movement distance of the clamping component 33, ensuring consistent traction length each time and thus guaranteeing the uniformity of the gaps between the reflective film 6 on the insulating film 7. This design is suitable for high-speed continuous production, improving production efficiency while maintaining quality.

[0052] In this embodiment, the clamping member 33 can be a gripper, a friction roller, or an elastic clamping plate, as long as it can meet the clamping requirements.

[0053] This embodiment provides a film processing device, such as... Figure 8 and Figure 9 As shown, the laminating film processing apparatus includes a laminating film belt support platform 34 and a hot-pressing laminating mechanism 37, as described above, disposed at at least one of the opposite ends of the laminating film belt support platform 34.

[0054] In this embodiment, the hot-pressing coating mechanism 37 can be set at either end of the laminating film belt carrier platform 34, or at both ends of the laminating film belt carrier platform 34. When the laminating film processing device adopts the layout of setting the hot-pressing coating mechanism 37 at both ends, the second traction components 22 can be set together to form a double-headed traction mechanism 36, which greatly improves production efficiency. When one end is changing materials or undergoing maintenance, the other end can continue production, reducing equipment idle time. The laminating film belt carrier platform 34 provides a guarantee for the stable conveying of the laminating film belt, ensuring the continuity and stability of the entire production process.

[0055] In the optional technical solution of this embodiment, the laminating film processing device further includes a seventh drive source and at least one pressure roller 35 disposed on the laminating film belt support platform 34. The seventh drive source is configured to drive the pressure roller 35 to rise and fall to avoid the second traction component 22 and press down the laminating film belt.

[0056] In this embodiment, the lifting function of the pressure roller 35 is controlled by the seventh drive source. It rises to avoid obstruction when the second traction component 22 moves, and lowers to press the laminated film belt when pressing is required. This avoids interference between the second traction mechanism and the pressure roller 35, while ensuring the flatness of the laminated film belt during transportation. The pressure of the pressure roller 35 can be adjusted according to the characteristics of the film material, adapting to the production needs of laminated film belts made of different materials.

[0057] In the optional technical solution of this embodiment, the laminating film processing device further includes an eighth drive source, which is configured to drive the pressure roller 35 to reciprocate along the extension direction of the laminating film belt support platform 34.

[0058] In this embodiment, the eighth drive source drives the pressure roller 35 to reciprocate along the extension direction of the laminating film belt support platform 34. This not only presses the laminating film belt tightly but also smooths it out, eliminating wrinkles or air bubbles on the laminating film belt. This dynamic pressing method further improves the bonding quality of the laminating film belt. At the same time, it simplifies the equipment structure, achieving multiple functions with the same set of pressure rollers 35.

[0059] It should be noted that there should be at least two sets of pressure rollers 35. If only pressing is required, two sets can be set; if lateral smoothing is required, one roller can press on one side while the other moves laterally.

[0060] It should be noted that the drive source in this application is a piston cylinder (including a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder), a linear module, or a motor.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
