Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing equipment technology, and in particular to a film application system and film application method. Background Technology

[0002] To increase the area of ​​photovoltaic modules exposed to sunlight and improve photoelectric conversion efficiency, many manufacturers have begun to install reflective film strips on the cover plates of photovoltaic modules. The reflective film strips can effectively reflect sunlight that passes through the gaps between cells and between cell strings back onto the cells, thereby making full use of the sunlight shining on the photovoltaic modules and improving the photoelectric conversion efficiency.

[0003] Currently, when fixing reflective film strips to the cover plate of photovoltaic modules, it is often necessary to first heat and adhere the first set of reflective film strips to a predetermined position on the cover plate using a first heating mechanism at the first film-applying station. Then, the cover plate is transported to a second film-applying station, where a second heating mechanism heats and adheres the second set of reflective film strips to a predetermined position on the cover plate. The second set of reflective film strips is perpendicular to the first set. Because the two sets of reflective film strips on the cover plate need to be applied at two separate film-applying stations, the film-applying efficiency of the cover plate is low. Moreover, this film-applying method requires two film-applying stations for the cover plate, resulting in a large space requirement for the equipment used to apply the film to the cover plate. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a film application system and method, which adopts the following technical solution:

[0006] The supporting device has a supporting surface for supporting the cover plate;

[0007] The first film feeding device is used to feed the first film strip extending along the first horizontal direction to the cover plate located on the support surface, and the second film feeding device is used to feed the second film strip extending along the second horizontal direction to the cover plate located on the support surface. The first film strip and the second film strip are arranged alternately on the cover plate located on the support surface, and the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0008] The heating mechanism is used to heat the first membrane strip and / or the second membrane strip so that the first membrane strip and the second membrane strip release their adhesiveness and adhere to the cover plate.

[0009] Based on the above-mentioned film application system, the support device provides reliable and stable support for the cover plate during the bonding process of the reflective film strip, improving the bonding reliability and accuracy of the reflective film strip. Moreover, both the first and second film feeding devices feed the film strip onto the cover plate located on the support surface of the support device, eliminating the need to feed the cover plate. The first and second film strips, which are perpendicular to each other, can be bonded to the cover plate using a single heating mechanism on the same support surface. Compared with existing film application equipment that requires two film application stations, the film application system of this application can improve bonding efficiency, simplify the mechanism settings of the entire film application system, reduce costs, and reduce the space occupied by the entire film application system.

[0010] Optionally, the first film feeding device includes a first feeding mechanism, a first film pulling mechanism, and a first displacement mechanism;

[0011] The first feeding mechanism is used to supply the first film strip, and the first film pulling mechanism includes a first clamp for clamping the first end of the first film strip and a second clamp for clamping the second end of the first film strip.

[0012] The first displacement mechanism includes a first transfer component driven by a first chuck and a second transfer component driven by a second chuck; the first transfer component is used to drive the first chuck to move along a first horizontal direction and a vertical direction; the second transfer component is used to drive the second chuck to move along the first horizontal direction and a vertical direction.

[0013] Based on the above-mentioned first feeding mechanism, first film pulling mechanism and first displacement mechanism, the online supply and handling of the first film strip is realized, and the first film strip can be moved from the first feeding mechanism to the set position on the cover plate to complete the transportation of the first film strip.

[0014] Optionally, the first film feeding device may further include a first pressing assembly and a first cutting assembly;

[0015] The first feeding mechanism is used to continuously release the first membrane strip;

[0016] One of the first clamp and the second clamp is used to clamp the free end of the first membrane strip and pull the first membrane strip out of the predetermined length;

[0017] Between the first clamp and the second clamp and the first feeding mechanism, a first pressing component and a first cutting component are sequentially arranged along the pulling direction of the first film strip;

[0018] The first clamping assembly and the other of the first clamp and the second clamp are respectively used to fix the first membrane strip after it has been pulled out to a predetermined length, and the first cutting assembly is used to cut the first membrane strip.

[0019] Based on the above-mentioned first clamping component and first cutting component, the free end of the first membrane strip can be pulled out to a predetermined length in conjunction with the first clamp or the second clamp. Then, the front and rear sides of the tail end of the first membrane strip are clamped and fixed by the first clamp or the second clamp and the first clamping component, respectively. Finally, the first cutting component is used to cut at the tail end position between the two, thereby processing a first membrane strip with a predetermined length.

[0020] Optionally, the first clamp and the second clamp are configured to alternately clamp the free end of the first membrane strip and pull the first membrane strip out of a predetermined length.

[0021] Based on the above-mentioned configuration of the first and second clamps, the first and second clamps can work alternately in a cycle to quickly and efficiently complete the transport of the first membrane strip.

[0022] Optionally, the first film feeding device further includes a first connecting frame and a second connecting frame. The number of the first feeding mechanism, the number of the first clamps and the number of the second clamps are the same as the number of the first film strips and correspond one-to-one. Each first clamp is arranged on the first connecting frame along the second horizontal direction. The first connecting frame is driven to be connected to the first transfer component. Each second clamp is arranged on the second connecting frame along the second horizontal direction. The second connecting frame is driven to be connected to the second transfer component.

[0023] Based on the configuration of the first connecting frame and the second connecting frame, multiple first clamps and multiple second clamps can move synchronously in the first horizontal direction, thereby synchronously driving multiple first membrane strips to be laid onto the cover plate together; this not only improves the conveying efficiency of the first membrane strips, but also improves the accuracy of the conveying position of all the first membrane strips, ensuring that the two ends of all the first membrane strips are flush in the second horizontal direction.

[0024] Optionally, the second film feeding device includes a second feeding mechanism, a second film pulling mechanism, and a second displacement mechanism;

[0025] The second feeding mechanism is used to supply the second film strip, and the second film pulling mechanism includes a third clamp for clamping the first end of the second film strip and a fourth clamp for clamping the second end of the second film strip.

[0026] The second displacement mechanism includes a third transfer component driven by a third chuck and a fourth transfer component driven by a fourth chuck; the third transfer component is used to drive the third chuck to move along a second horizontal direction and a vertical direction; the fourth transfer component is used to drive the fourth chuck to move along a second horizontal direction and a vertical direction.

[0027] Based on the above-mentioned second feeding mechanism, second film pulling mechanism and second displacement mechanism, the online supply and handling of the second film strip is realized, and the second film strip can be moved from the second feeding mechanism to the set position on the cover plate to complete the transportation of the second film strip.

[0028] Optionally, the second film feeding device may further include a second pressing assembly and a second cutting assembly;

[0029] The second feeding mechanism is used to continuously release the second membrane strip;

[0030] One of the third and fourth clamps is used to hold the free end of the second membrane strip and pull the second membrane strip out of the predetermined length;

[0031] Between the third and fourth clamps and the second feeding mechanism, a second pressing assembly and a second cutting assembly are sequentially arranged along the pulling direction of the second film strip;

[0032] The second clamping assembly and the other of the third and fourth clamps are used to fix the second membrane strip after it has been pulled out to a predetermined length, and the second cutting assembly is used to cut the second membrane strip.

[0033] Based on the above-mentioned second clamping component and second cutting component, the free end of the second membrane strip can be pulled out to a predetermined length in conjunction with the third clamp or fourth clamp. Then, the front and rear sides of the tail end of the second membrane strip are clamped and fixed by the third clamp or fourth clamp and the second clamping component. Finally, the second cutting component is used to cut at the tail end position between the two, thereby processing a second membrane strip with a predetermined length.

[0034] Optionally, the third and fourth clamps are configured to alternately clamp the free end of the second membrane strip and pull the second membrane strip out of a predetermined length.

[0035] Based on the above-mentioned configuration of the third and fourth clamps, the third and fourth clamps can work alternately in a cycle to quickly and efficiently complete the transport of the second membrane strip.

[0036] Optionally, the second film feeding device further includes a third connecting frame and a fourth connecting frame. The number of the second feeding mechanism, the third clamp, and the fourth clamp are the same as the number of the second film strip and correspond one-to-one. Each third clamp is arranged on the third connecting frame along the first horizontal direction. The third connecting frame is driven to be connected to the third transfer component. Each fourth clamp is arranged on the fourth connecting frame along the first horizontal direction. The fourth connecting frame is driven to be connected to the fourth transfer component.

[0037] Based on the aforementioned third and fourth connecting frames, multiple third and fourth clamps can move synchronously in the second horizontal direction, thereby synchronously driving multiple second membrane strips to move together. This not only improves the conveying efficiency of the second membrane strips but also enhances the accuracy of the conveying position of all second membrane strips, ensuring that both ends of all second membrane strips are flush in the first horizontal direction.

[0038] Optionally, the second film feeding device further includes a transfer platform and a material transfer mechanism. The transfer platform extends along the second horizontal direction to support the second film strip taken out from the second feeding mechanism by the second film pulling mechanism. The material transfer mechanism is used to transfer the second film strip on the transfer platform to the cover plate located on the support surface.

[0039] Based on the setup of the transfer platform and the material transfer mechanism, the first film feeding device and the second film feeding device can be positioned on opposite sides of the supporting device in one direction. This allows the first film feeding device to directly feed the first film strip onto the cover plate, while simultaneously, the second film feeding device can feed the second film strip onto the transfer platform. After the first film strip is laid out, the material transfer mechanism then feeds the second film strip onto the cover plate. This facilitates the simultaneous preparation work before film strip feeding by the first and second film feeding devices, thereby optimizing the spatial layout and improving efficiency.

[0040] Optionally, the material transfer mechanism includes a material transfer frame, a material transfer assembly, and a displacement assembly;

[0041] The transfer platform is located on one side of the supporting device along the first horizontal direction;

[0042] The displacement component is connected to the transfer rack drive and is used to drive the transfer rack to lift and move along the first horizontal direction;

[0043] The material transfer assembly includes a picking unit located below the material transfer frame. The picking unit is used to pick up each second film strip on the transfer platform and transfer the second film strip along the first horizontal direction to the cover plate located on the support surface.

[0044] A specific material transfer mechanism is provided, which picks up the second membrane strip through a pickup unit and then drives the pickup unit through a displacement component to carry out the transfer of the second membrane strip.

[0045] Optionally, the heating mechanism is located below the transfer rack, and the picking unit can move closer to or further away from the transfer rack in a vertical direction;

[0046] When the pickup unit moves away from the transfer rack to the first position, it is lower than the heating end of the heating mechanism; when the pickup unit moves towards the transfer rack to the second position, it is flush with the heating end of the heating mechanism.

[0047] By mounting the heating mechanism and the pickup unit together on the transfer rack, and allowing the pickup unit to move vertically towards or away from the transfer rack, when a film strip needs to be picked up, the pickup unit is first positioned in a first position, lower than the heating end of the heating mechanism. The displacement component drives the transfer rack to descend and approach the second film strip, allowing the pickup unit to pick it up. After the pickup unit places the picked-up second film strip onto the cover plate, the displacement component drives the transfer rack to descend, simultaneously moving the pickup unit towards the transfer rack to a second position, making the pickup unit flush with the heating end of the heating mechanism. The heating end of the heating mechanism then contacts and heats the film strip, causing it to adhere to the cover plate. Therefore, this application can simultaneously achieve the handling of the second film strip and the heating and bonding of the first and / or second film strips, not only reducing equipment costs but also improving the smoothness of handling and heating / bonding the reflective film strips, thus increasing the bonding efficiency of the reflective film strips.

[0048] Optionally, the heating mechanism may further include a third clamping assembly connected to the transfer rack, the third clamping assembly being used at least to clamp the first and / or second membrane strips when the heating end of the heating mechanism is away from the first and / or second membrane strips.

[0049] Based on the aforementioned third pressing component, when the heating end of the heating mechanism moves upward and just leaves the film strip, the third pressing component can press firmly onto the film strip to ensure that the film strip will not be driven away from the cover plate of the photovoltaic module by the heating end due to adhesion to the heating end, thereby improving the connection reliability between the film strip and the cover plate.

[0050] Optionally, there are two sets of second film feeding devices. The two sets of second film feeding devices are arranged opposite each other in the second horizontal direction. The two sets of second film feeding devices respectively transport the two sets of second film strips to the cover plate located on the support surface, so that the two sets of second film strips are respectively located in the first half and the second half arranged in the second horizontal direction on the cover plate.

[0051] Based on the above-mentioned second film feeding device, when two sets of second film strips need to be laid in the first half and the second half of the cover plate in the second horizontal direction, the second film feeding device is set into two sets accordingly, so that the two sets of second film strips can be conveyed at the same time, thereby improving the laying efficiency of reflective film strips on the cover plate.

[0052] Optionally, the heating mechanism includes a plurality of first heating components, each of which is used to apply spot heating to the first membrane strip and / or the second membrane strip, so that the first membrane strip and the second membrane strip release their adhesiveness and adhere to the cover plate;

[0053] or,

[0054] The heating mechanism includes at least one second heating component for surface heating of the first and / or second membrane strips, such that the first and second membrane strips release their adhesiveness and adhere to the cover plate.

[0055] Based on the heating mechanism described above, the heating method for the reflective film strip can be selected according to requirements.

[0056] Optionally, each first heating component is used to heat the intersection of the first membrane strip and the second membrane strip, so that the first membrane strip and the second membrane strip simultaneously release their adhesiveness and adhere to the cover plate.

[0057] Since the first heating component only heats the intersection of the first and second film strips, it can reduce the heating area while enabling the first and second film strips to be bonded to the cover plate simultaneously with a single heating, thus further improving the film application efficiency.

[0058] Optionally, the first heating component includes a heating block and a heating head; the heating head is mounted on the heating block, the heating block is used to heat the heating head, and the heating head is used to heat the first membrane strip and / or the second membrane strip.

[0059] or,

[0060] The second heating component is an infrared lamp box, which is used to irradiate and heat the first membrane strip and / or the second membrane strip; or, the second heating component includes a heating plate, which is used to contact and heat the first membrane strip and / or the second membrane strip.

[0061] Based on the heating mechanism described above, selective point heating or surface heating of the reflective film strip can be achieved.

[0062] Optionally, the supporting device includes a conveying mechanism for conveying the cover plate and a straightening mechanism;

[0063] The conveying surface of the conveying mechanism forms a supporting surface;

[0064] The straightening mechanism is located around the conveying mechanism and is used to clamp the cover plate located on the support surface to straighten the position of the cover plate.

[0065] Based on the above-mentioned conveying mechanism, the cover plate can be continuously conveyed into place, and the setting of the straightening mechanism can correct the position of the cover plate to ensure the positional accuracy of subsequent film application.

[0066] Optionally, the supporting device includes a conveying mechanism for conveying the cover plate, a supporting platform for supporting the cover plate, a platform lifting mechanism for driving the supporting platform to rise and fall, and a regulating mechanism.

[0067] A support surface is formed on the support platform;

[0068] The support platform has a vertical clearance passage for avoiding the conveying mechanism;

[0069] The alignment mechanism is located on the periphery of the support platform and is used to clamp the cover plate located on the support surface to align the position of the cover plate.

[0070] Based on the above-mentioned conveying mechanism, the cover plate can be continuously conveyed to the desired position. The support platform can lift the back plate after it is conveyed to the desired position to remove it from the conveying mechanism, providing stable and reliable support for the back plate. The alignment mechanism can correct the position of the cover plate to ensure the positional accuracy of subsequent film application.

[0071] Secondly, this application provides a method for applying a screen protector, comprising the following steps:

[0072] Support the cover plate in the predetermined position;

[0073] A first membrane strip and a second membrane strip are respectively laid on a cover plate located at a predetermined position. The first membrane strip and the second membrane strip are arranged alternately on the cover plate and are perpendicular to each other.

[0074] After the first membrane strip is laid, heat the first membrane strip; after the second membrane strip is laid, heat the second membrane strip, so that the first and second membrane strips release their adhesiveness and adhere to the cover plate; or, after the first and second membrane strips are fully laid, heat the first and second membrane strips, so that the first and second membrane strips release their adhesiveness and adhere to the cover plate.

[0075] Based on the above film application method, the cover plate can complete the laying and bonding of two sets of film strips in one station, thereby improving the laying efficiency of reflective film strips on the cover plate. After the first and second film strips are laid, the first and / or second film strips are bonded together. This method allows the first and second film strips to share a heating mechanism, and the bonding of the two sets of film strips can be completed in one cycle by one heating mechanism, thereby significantly improving the bonding efficiency of reflective film strips and reducing the cost of the entire film application system.

[0076] Optionally, after all the first and second membrane strips have been laid, the first and second membrane strips are heated, including heating the intersection of the first and second membrane strips so that the first and second membrane strips simultaneously release their adhesiveness and adhere to the cover plate.

[0077] By heating only at the intersection of the first and second film strips, the heating area can be reduced while allowing the first and second film strips to be bonded to the cover plate simultaneously with a single heating, further improving the film application efficiency.

[0104] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0105] Currently, when fixing reflective film strips to the cover plate of photovoltaic modules, it is often necessary to first heat and adhere the first set of reflective film strips to a predetermined position on the cover plate using a first heating mechanism at the first film-applying station. Then, the cover plate is transported to a second film-applying station, where a second heating mechanism heats and adheres the second set of reflective film strips to a predetermined position on the cover plate. The second set of reflective film strips is perpendicular to the first set. Because the two sets of reflective film strips on the cover plate need to be applied at two separate film-applying stations, the film-applying efficiency of the cover plate is low. Moreover, this film-applying method requires two film-applying stations for the cover plate, resulting in a large space requirement for the equipment used to apply the film to the cover plate.

[0106] Based on this, this application provides a film application system and method. By setting up a support device, a reliable and stable support can be provided to the cover plate during the bonding process of the reflective film strip, thereby improving the bonding reliability and accuracy of the reflective film strip. Moreover, both the first and second film feeding devices feed the film strip onto the cover plate located on the support surface of the support device, eliminating the need to feed the cover plate. The first and second film strips, which are perpendicular to each other, can be bonded to the cover plate on the same support surface using a set of heating mechanisms. Compared with existing film application equipment that requires two film application stations, the film application system of this application can not only improve bonding efficiency, but also simplify the mechanism settings of the entire film application system, reduce costs, and reduce the space occupied by the entire film application system.

[0107] The present application will be described in detail below through specific embodiments.

[0108] Firstly, referring to Figures 1 to 18 As shown, this embodiment provides a film application system, which includes a first film feeding device 2, a second film feeding device 3, a heating mechanism, and a supporting device 4. The supporting device 4 has a supporting surface for supporting a cover plate 6. The first film feeding device 2 is used to feed a first film strip 51 extending along a first horizontal direction onto the cover plate 6 located on the supporting surface. The second film feeding device 3 is used to feed a second film strip 52 extending along a second horizontal direction onto the cover plate 6 located on the supporting surface. The first film strip 51 and the second film strip 52 are arranged alternately on the cover plate 6 located on the supporting surface, and the first horizontal direction and the second horizontal direction are perpendicular to each other. The heating mechanism is used to heat the first film strip 51 and / or the second film strip 52 so that the first film strip 51 and the second film strip 52 release their adhesiveness and adhere to the cover plate 6.

[0109] Optionally, the first membrane strip 51 and the second membrane strip 52 can be laid on the cover plate 6 according to a set method, and then the first membrane strip 51 and the second membrane strip 52 can be heated by a heating mechanism. Alternatively, the first membrane strip 51 can be laid on the set position of the cover plate 6 first, and then the first membrane strip 51 can be heated by the heating mechanism. Then the second membrane strip 52 can be laid on the set position of the cover plate 6, and finally the second membrane strip 52 can be heated by the heating mechanism.

[0110] The film application system provided in this embodiment, through the setting of the support device 4, can provide reliable and stable support for the cover plate 6 during the bonding process of the reflective film strip, thereby improving the bonding reliability and accuracy of the reflective film strip. Moreover, both the first film feeding device 2 and the second film feeding device 3 feed the film strip onto the cover plate 6 located on the support surface of the support device 4. Without the need to feed the cover plate 6, the mutually perpendicular first film strip 51 and second film strip 52 can complete the bonding work onto the cover plate 6 at the same support surface using a set of heating mechanisms. Compared with the existing film application equipment that requires two film application stations, the film application system of this application can not only improve the bonding efficiency, but also simplify the mechanism settings of the entire film application system, reduce costs, and reduce the space occupied by the entire film application system.

[0111] Continue to refer to Figures 1 to 4 As shown, in some embodiments, the first film feeding device 2 includes a first feeding mechanism 21, a first film pulling mechanism 22, and a first displacement mechanism; the first feeding mechanism 21 is used to supply the first film strip 51, and the first film pulling mechanism 22 includes a first clamp 221 for clamping the first end of the first film strip 51 and a second clamp 222 for clamping the second end of the first film strip 51. The first end of the first film strip 51 can be either the head end or the tail end of the first film strip 51; the first displacement mechanism includes a first transfer component drivenly connected to the first clamp 221 and a second transfer component drivenly connected to the second clamp 222; the first transfer component is used to drive the first clamp 221 to move along a first horizontal direction and a vertical direction; the second transfer component is used to drive the second clamp 222 to move along the first horizontal direction and a vertical direction; wherein, the first transfer component and the second transfer component can be one or more combinations of a conveyor belt, a conveyor chain, an electric cylinder, a pneumatic cylinder, and a linear motor.

[0112] By setting up the first feeding mechanism 21, the first film pulling mechanism 22 and the first displacement mechanism, the online supply and handling of the first film strip 51 is realized. The first film strip 51 can be moved from the first feeding mechanism 21 to the set position on the cover plate 6 to complete the transportation of the first film strip 51.

[0113] Optionally, the first feeding mechanism 21 may be pre-stored with a first film strip 51 of a predetermined length. By setting the first feeding mechanism 21, the first film pulling mechanism 22 can always move the first film strip 51 away from the first feeding mechanism 21 from the same position, thereby simplifying the movement mode of the first displacement mechanism and reducing the overall cost.

[0114] Optionally, the first feeding mechanism 21 can also be used to supply continuous film strips, and then cut the continuous film strips into first film strips 51 with a predetermined length by cutting. In this case, the first film feeding device 2 also includes a first pressing component 23 and a first cutting component 24. The first feeding mechanism 21 is used to continuously release the first film strips 51. Optionally, the first feeding mechanism 21 can include a material roll for winding the first film strips 51 and a motor for driving the material roll to rotate. Multiple guide wheels can be set between the material roll and the discharge position to apply pre-tension to the first film strips 51 to ensure that the first film strips 51 can be conveyed according to the set route.

[0115] One of the first clamp 221 and the second clamp 222 is used to clamp the free end of the first film strip 51 and pull the first film strip 51 out to a predetermined length; the other of the first clamp 221 and the second clamp 222 are arranged sequentially with the first feeding mechanism 21 along the pulling direction of the first film strip 51, with a first pressing component 23 and a first cutting component 24; the first pressing component 23 and the other of the first clamp 221 and the second clamp 222 are respectively used to fix the first film strip 51 after it is pulled out to a predetermined length, and the first cutting component 24 is used to cut the first film strip 51.

[0116] By using the first clamping component 23 and the first cutting component 24, the free end of the first film strip 51 can be pulled out to a predetermined length using the first clamp 221 or the second clamp 222. Then, at the tail end of the first film strip 51, the front and rear sides of the tail end of the first film strip 51 can be clamped and fixed using the first clamp 221 or the second clamp 222 and the first clamping component 23, respectively. Finally, the first cutting component 24 can be used to cut at the tail end between the two, thereby producing a first film strip 51 with a predetermined length.

[0117] In a further embodiment, the first clamp 221 and the second clamp 222 are configured to alternately clamp the free end of the first membrane strip 51 and pull the first membrane strip 51 out to a predetermined length; that is, the first clamp 221 can be used to clamp the free end of the first membrane strip 51 and pull the first membrane strip 51 out to a predetermined length first, at which point the second clamp 222 clamps the tail end of the first membrane strip 51. Through the synchronous movement of the first clamp 221 and the second clamp 222, the first membrane strip 51 is transported to the desired position. After the first membrane strip 51 has been transported, the second membrane strip 52 only needs to move a very short distance to move the next membrane strip 51. The free end of the first membrane strip 51 is clamped, and the next first membrane strip 51 is pulled out to a predetermined length. Then, the first chuck 221 moves to the discharge position of the first feeding mechanism 21 and clamps the tail end of the next first membrane strip 51. The next first membrane strip 51 is transported to the designated position through the synchronous movement of the second chuck 222 and the first chuck 221. Similarly, the third, fourth, and so on first membrane strips 51 are transported. Throughout the process, the first chuck 221 and the second chuck 222 work alternately in a cycle to quickly and efficiently complete the transport of two or more first membrane strips 51.

[0118] Continue to refer to Figure 3 and Figure 8 As shown, the first film feeding device 2 further includes a first connecting frame 251 and a second connecting frame. The number of the first feeding mechanism 21, the first clamp 221, and the second clamp 222 are all the same as the number of the first film strips 51 and correspond one-to-one. Each first clamp 221 is arranged on the first connecting frame 251 along the second horizontal direction, and the first connecting frame 251 is driven to connect with the first transfer component. Each second clamp 222 is arranged on the second connecting frame along the second horizontal direction, and the second connecting frame is driven to connect with the second transfer component. In other words, by setting the first connecting frame 251 and the second connecting frame, the synchronous movement of multiple first clamps 221 and multiple second clamps 222 in the first horizontal direction can be realized, thereby synchronously driving multiple first film strips 51 to be laid onto the cover plate 6 together. This not only improves the conveying efficiency of the first film strips 51, but also improves the accuracy of the conveying position of all the first film strips 51, ensuring that the two ends of all the first film strips 51 are flush in the second horizontal direction.

[0119] In some embodiments, the second film feeding device 3 includes a second feeding mechanism 31, a second film pulling mechanism 32, and a second displacement mechanism; the second feeding mechanism 31 is used to supply the second film strip 52, and the second film pulling mechanism 32 includes a third clamp 321 for clamping the first end of the second film strip 52 and a fourth clamp 322 for clamping the second end of the second film strip 52. The first end of the second film strip 52 can be either the head end or the tail end of the second film strip 52; the second displacement mechanism includes a third transfer component drivenly connected to the third clamp 321 and a fourth transfer component drivenly connected to the fourth clamp 322; the third transfer component is used to drive the third clamp 321 to move along a second horizontal direction and a vertical direction; the fourth transfer component is used to drive the fourth clamp 322 to move along a second horizontal direction and a vertical direction; wherein, the third transfer component and the fourth transfer component can be one or more combinations of a conveyor belt, a conveyor chain, an electric cylinder, a pneumatic cylinder, and a linear motor.

[0120] By setting up the second feeding mechanism 31, the second film pulling mechanism 32, and the second displacement mechanism, the online supply and handling of the second film strip 52 are realized. The second film strip 52 can be moved from the second feeding mechanism 31 to the set position on the cover plate 6, thus completing the transportation of the second film strip 52.

[0121] Optionally, the second feeding mechanism 31 may have a second film strip 52 of a predetermined length stored in advance. By setting the second feeding mechanism 31, the second film pulling mechanism 32 can always move the second film strip 52 away from the second feeding mechanism 31 from the same position, thereby simplifying the movement mode of the second displacement mechanism and achieving the purpose of reducing the overall cost and making the control of the second displacement mechanism simpler.

[0122] Optionally, the second feeding mechanism 31 can also be used to supply a continuous film strip, and then cut the continuous film strip into a second film strip 52 with a predetermined length by cutting. In this case, the second film feeding device 3 also includes a second pressing component 33 and a second cutting component 34. The second feeding mechanism 31 is used to continuously release the second film strip 52. Optionally, the second feeding mechanism 31 can include a material roll for winding the second film strip 52 and a motor for driving the material roll to rotate. Multiple guide wheels can be set between the material roll and the discharge position to apply pre-tension to the second film strip 52 to ensure that the second film strip 52 can be conveyed according to the set route.

[0123] Optionally, one of the third clamp 321 and the fourth clamp 322 is used to clamp the free end of the second membrane strip 52 and pull the second membrane strip 52 out of a predetermined length; the other of the third clamp 321 and the fourth clamp 322 is provided with a second pressing component 33 and a second cutting component 34 in sequence along the pulling direction of the second membrane strip 52 between the second clamp 321 and the second feeding mechanism 31; the second pressing component 33 and the other of the third clamp 321 and the fourth clamp 322 are respectively used to fix the second membrane strip 52 after it has been pulled out of a predetermined length, and the second cutting component 34 is used to cut the second membrane strip 52.

[0124] With the second clamping component 33 and the second cutting component 34, the free end of the second membrane strip 52 can be pulled out to a predetermined length by cooperating with the third clamp 321 or the fourth clamp 322. Then, at the tail end of the second membrane strip 52, the front and rear sides of the tail end of the second membrane strip 52 are clamped and fixed by the third clamp 321 or the fourth clamp 322 and the second clamping component 33, respectively. Finally, the second cutting component 34 is used to cut at the tail end between the two, thereby processing a second membrane strip 52 with a predetermined length.

[0125] Furthermore, the third clamp 321 and the fourth clamp 322 are configured to alternately clamp the free end of the second membrane strip 52 and pull the second membrane strip 52 out to a predetermined length; that is, the third clamp 321 can be used to clamp the free end of the second membrane strip 52 and pull the second membrane strip 52 out to a predetermined length first, at which point the fourth clamp 322 clamps the tail end of the second membrane strip 52. Through the synchronous movement of the third clamp 321 and the fourth clamp 322, the second membrane strip 52 is transported into place. After the transport of the second membrane strip 52 is completed, the second membrane strip 52 only needs to move a very short distance before the next second membrane strip 52 is transported into place. The free end of the membrane strip 52 is clamped, and the next second membrane strip 52 is pulled out to a predetermined length. Then, the third chuck 321 moves to the discharge position of the second feeding mechanism 31 and clamps the tail end of the next second membrane strip 52. The next second membrane strip 52 is transported to its position through the synchronous movement of the fourth chuck 322 and the third chuck 321. Similarly, the third, fourth and so on second membrane strips 52 are transported. Throughout the process, the third chuck 321 and the fourth chuck 322 work alternately in a cycle, quickly and efficiently completing the transport of two or more second membrane strips 52.

[0126] In some embodiments, the second film feeding device 3 further includes a third connecting frame 351 and a fourth connecting frame. The number of the second feeding mechanism 31, the third clamp 321, and the fourth clamp 322 are all the same as the number of the second film strips 52 and correspond one-to-one. Each third clamp 321 is arranged on the third connecting frame 351 along the first horizontal direction, and the third connecting frame 351 is driven to connect with the third transfer component. Each fourth clamp 322 is arranged on the fourth connecting frame along the first horizontal direction, and the fourth connecting frame is driven to connect with the fourth transfer component. That is, by setting the third connecting frame 351 and the fourth connecting frame, the synchronous movement of multiple third clamps 321 and multiple fourth clamps 322 in the second horizontal direction can be realized, thereby synchronously driving multiple second film strips 52 to move together. This not only improves the conveying efficiency of the second film strips 52, but also improves the accuracy of the conveying position of all the second film strips 52, ensuring that the two ends of all the second film strips 52 are flush in the first horizontal direction.

[0127] Continue to refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the second film feeding device 3 also includes a transfer platform 36 and a transfer mechanism 37. The transfer platform 36 extends along a second horizontal direction and is used to support the second film strip 52 taken out from the second feeding mechanism 31 by the second film pulling mechanism 32. The transfer mechanism 37 is used to transfer the second film strip 52 on the transfer platform 36 to the cover plate 6 located on the support surface. Optionally, the number of second film strips 52 is less than the number of first film strips 51, thereby reducing the structural complexity of the transfer platform 36 and the transfer mechanism 37.

[0128] Since the first film strip 51 and the second film strip 52 are perpendicular to each other, based on the aforementioned transfer platform 36 and material transfer mechanism 37, the first film feeding device 2 and the second film feeding device 3 can be positioned on both sides of the supporting device 4 in the same direction. This allows the first film feeding device 2 to directly feed the first film strip 51 onto the cover plate 6, while the second film feeding device 3 can simultaneously feed the second film strip 52 onto the transfer platform 36. After the first film strip 51 is laid out, the material transfer mechanism 37 feeds the second film strip 52 onto the cover plate 6. This facilitates the simultaneous preparation work before film strip feeding by the first film feeding device 2 and the second film feeding device 3, thereby optimizing the spatial arrangement and improving efficiency.

[0129] In some embodiments, a plurality of adsorption hole groups are arranged at intervals along a first horizontal direction on the transfer platform 36. Each adsorption hole group includes a plurality of adsorption holes arranged at intervals along a second horizontal direction. Each adsorption hole group is used to adsorb a second membrane strip 52 to implement the positioning of each second membrane strip 52 laid on the transfer platform 36.

[0130] The material transfer mechanism 37 includes a material transfer frame 371, a material transfer component 372, and a displacement component 373. The transfer platform 36 is located on one side of the support device 4 along the first horizontal direction. The displacement component 373 is driven to connect with the material transfer frame 371 and is used to drive the material transfer frame 371 to rise and fall and to move horizontally along the first horizontal direction. The material transfer component 372 includes a picking part 3721, which is located below the material transfer frame 371. The picking part 3721 is used to pick up each second film strip 52 on the transfer platform 36 and transfer the second film strip 52 along the first horizontal direction to the cover plate 6 located on the support surface.

[0131] Optionally, the pickup unit 3721 can be a suction cup connected to the air source. The suction cup can adsorb and fix the second membrane strip 52 by forming a negative pressure, and can also release the negative pressure to detach the second membrane strip 52 from it.

[0132] Optionally, multiple transfer racks 371 are provided, and the transfer assembly 372 includes multiple picking parts 3721. Multiple picking parts 3721 are arranged along the second horizontal direction on each transfer rack 371. The multiple picking parts 3721 on each transfer rack 371 are used to pick up a second film strip 52.

[0133] In some embodiments, the displacement component 373 may include a track 3731 extending along a first horizontal direction and a plurality of lifting drive members 3734. The lifting drive members 3734 are slidably disposed on the track 3731 along the first horizontal direction. The movable ends of the lifting drive members 3734 are connected one-to-one with the transfer rack 371 and are used to drive the transfer rack 371 to lift.

[0134] Furthermore, the displacement assembly 373 also includes a spacing structure, which includes a spacing drive unit 3732 and movers 3733 that are connected one-to-one with the lifting drive unit 3734. Each mover 3733 is mounted on the track 3731. The spacing drive unit 3732 is used to drive each mover 3733 to slide in the first horizontal direction, so that there is a set distance between any two adjacent transfer racks 371. Thus, by using the spacing assembly, after all transfer racks 371 move in the first horizontal direction, the distance between any two transfer racks 371 is the same. By setting a spacing structure, the spacing between each second membrane strip 52 on the transfer platform 36 can be set smaller than the spacing between the second membrane strips 52 to be laid on the cover plate 6, thereby reducing the size and footprint of the transfer platform 36. After picking up the second membrane strips 52 from the transfer platform 36, the material transfer mechanism 37 can perform spacing of each second membrane strip 52 during the transportation of the second membrane strips 52, so that all the second membrane strips 52 are evenly arranged on the cover plate 6 according to the set position.

[0135] In some embodiments, the heating mechanism is disposed below the transfer rack 371, and the picking part 3721 can move closer to or further away from the transfer rack 371 in a vertical direction; when the picking part 3721 moves away from the transfer rack 371 to a first position, it is lower than the heating end of the heating mechanism; when the picking part 3721 moves closer to the transfer rack 371 to a second position, it is flush with the heating end of the heating mechanism.

[0136] In this design, the heating mechanism and the pickup part 3721 are jointly mounted on the transfer rack 371, and the pickup part 3721 can move vertically towards or away from the transfer rack 371. When it is necessary to pick up the film strip, the pickup part 3721 is first positioned so that it is lower than the heating end of the heating mechanism. After the displacement component 373 drives the transfer rack 371 to descend and approach the second film strip 52, the pickup part 3721 can pick up the film strip. After the pickup part 3721 places the picked-up second film strip 52 onto the cover plate 6, the displacement component 373 drives the transfer rack 371 to descend, and at the same time moves the pickup part 3721 towards the direction of approaching the transfer rack 371 to the second position, so that the pickup part 3721 is flush with the heating end of the heating mechanism. The heating end of the heating mechanism can then contact the film strip and heat it, causing the film strip to adhere to the cover plate 6. As can be seen, this application can simultaneously realize the handling of the second film strip 52 and the heating and bonding of the first film strip 51 and / or the second film strip 52, which not only reduces equipment costs, but also improves the smoothness of handling and heating and bonding of reflective film strips, and improves the bonding efficiency of reflective film strips.

[0137] Optionally, the pickup unit 3721 is mounted on the transfer rack 371 in a way that allows it to float up and down via a spring. When the spring is in its natural state, the pickup unit 3721 moves to the first position. The lifting drive unit 3734 drives the transfer rack 371 to descend, and at the same time moves the pickup unit 3721 toward the direction of the transfer rack 371 to the second position. When the pickup unit 3721 is aligned with the heating end of the heating mechanism, the spring is in a compressed state.

[0138] Optionally, the heating mechanism may further include a third clamping assembly connected to the transfer rack 371, the third clamping assembly being used at least to clamp the first film strip 51 and / or the second film strip 52 when the heating end of the heating mechanism is away from the first film strip 51 and / or the second film strip 52.

[0139] Furthermore, the third pressing assembly includes a pressing structure 12, which includes an elastic connector 121 and a pressing block 122. The elastic connector 121 can elastically deform in the vertical direction. The pressing block 122 is connected to the transfer frame 371 through the elastic connector 121. The bottom of the pressing block 122 forms a pressing surface for pressing the film strip. When the elastic connector 121 is in its natural state, the pressing surface is lower than the heating end of the heating mechanism.

[0140] The optional working process of the third pressing component in the above embodiment is as follows: The transfer frame 371 drives the heating end of the third pressing component and the heating mechanism to descend. Since the elastic connector 121 is in its natural state, the pressing surface is lower than the heating end, so the pressing surface contacts the film strip first. As the transfer frame 371 continues to descend, the pressing block 122 presses the film strip while compressing the elastic connector 121. After the elastic connector 121 is compressed to a certain length, the heating end on the heating component begins to contact the film strip and begins to heat the film strip. During the process of the heating end heating the film strip, the pressing block 122 always provides a pressing force on the film strip to improve the stability of the film strip during heating.

[0141] After the membrane strip heating is completed, the transfer frame 371 drives the heating end of the third pressing component and the heating mechanism to rise. The heating end first leaves the membrane strip, while the pressure block 122 can maintain the pressure on the membrane strip under the action of the elastic connector 121 until the elastic connector 121 returns to its natural state. Only then does the pressure block 122 begin to detach from the membrane strip. Thus, even if the membrane strip is stuck to the heating end, the membrane strip will not be lifted by the heating end when the heating end leaves the membrane strip, ensuring the reliability of the connection between the membrane strip and the cover plate 6.

[0142] Furthermore, one pressure block 122 is provided, and a through hole 123 is provided on the pressure block 122 for the heating end to pass through; or, at least two pressure blocks 122 are provided, and each pressure block 122 is arranged at intervals along the circumference of the heating end, and a clearance space is formed between each pressure block 122 to avoid the heating end, and the heating end is used to pass through the clearance space to heat the film strip.

[0143] Optionally, the elastic connector 121 includes a guide post and a spring fitted on the guide post. The pressure block 122 is mounted on the transfer rack 371 vertically via the guide post. The upper end of the spring abuts against the transfer rack 371, and the lower end abuts against the pressure block 122.

[0144] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, there are two sets of second film feeding devices 3. The two sets of second film feeding devices 3 are arranged opposite each other in the second horizontal direction. The two sets of second film feeding devices 3 respectively transport the two sets of second film strips 52 to the cover plate 6 located on the support surface, so that the two sets of second film strips 52 are respectively located on the cover plate 6 in the first half and the second half arranged in the second horizontal direction.

[0145] When two sets of second film strips 52 need to be laid on the first half and the second half of the cover plate 6 in the second horizontal direction, the second film feeding device 3 is set into two sets accordingly, so that the two sets of second film strips 52 can be conveyed at the same time, thereby improving the laying efficiency of reflective film strips on the cover plate 6.

[0146] In some embodiments, the heating mechanism includes a plurality of first heating components 11, each first heating component 11 being used to perform point heating on the first film strip 51 and / or the second film strip 52, so that the first film strip 51 and the second film strip 52 release their adhesiveness and adhere to the cover plate 6, avoiding the entire surface of the cover plate 6 being heated, thus ensuring that the first film strip 51 and the second film strip 52 are smoothly adhered to the cover plate 6, and effectively reducing the deformation of the cover plate 6; or, the heating mechanism includes at least one second heating component, the second heating component being used to perform surface heating on the first film strip 51 and / or the second film strip 52, so that the first film strip 51 and the second film strip 52 release their adhesiveness and adhere to the cover plate 6.

[0147] Furthermore, each first heating component 11 is used to heat the intersection of the first film strip 51 and the second film strip 52, so that the first film strip 51 and the second film strip 52 simultaneously release their adhesiveness and adhere to the cover plate 6. The first heating component 11 only heats the intersection of the first film strip 51 and the second film strip 52, which can reduce the heating area while enabling the first film strip 51 and the second film strip 52 to simultaneously adhere to the cover plate 6 with a single heating, further improving the film application efficiency.

[0148] In some embodiments, both ends of each first membrane strip 51 intersect with the second membrane strip 52, and both ends of each second membrane strip 52 intersect with the first membrane strip 51; the first heating component 11 of the heating mechanism is used to heat at least the intersection points of both ends of each first membrane strip 51 and the intersection points of both ends of each second membrane strip 52.

[0149] By heating at least the intersection points of the two ends of each first film strip 51 and the intersection points of the two ends of each second film strip 52, it is ensured that at least the two end points of each reflective film strip can be bonded to the cover plate 6, thus ensuring the reliability of the connection between the reflective film strip and the cover plate 6.

[0150] The first heating component 11 is also used to heat at least one intersection point located in the middle of each first membrane strip 51 and at least one intersection point located in the middle of each second membrane strip 52.

[0151] It should be noted that the middle part of the first membrane strip 51 refers to any position between the two ends of the first membrane strip 51; the middle part of the second membrane strip 52 refers to any position between the two ends of the second membrane strip 52. This design can further increase the number of connection points between the first membrane strip 51 and the second membrane strip 52 and the cover plate 6, thereby improving the bonding reliability between the first membrane strip 51 and the second membrane strip 52 and the cover plate 6.

[0152] Continue to refer to Figures 9 to 15As shown, the first heating component 11 includes a heating block 111 and a heating head 112; the heating head 112 is mounted on the heating block 111, and the heating block 111 is used to heat the heating head 112. The heating head 112 is used to heat the first membrane strip 51 and / or the second membrane strip 52. The heating head 112 can move relative to the heating block 111 in the vertical direction. The heating head 112 can be connected to the heating block 111 via an elastic element, or the heating head 112 can be fixedly mounted on the heating block 111. Alternatively, the second heating component is an infrared lamp box, which is used to irradiate and heat the first membrane strip 51 and / or the second membrane strip 52. Optionally, the infrared lamp box can be positioned above the support device 4, and after the first membrane strip 51 and the second membrane strip 52 are laid in place, it irradiates and heats the cover plate 6. The first membrane strip 51 and the second membrane strip 52 are irradiated to release their adhesiveness and adhere to the cover plate 6; or, the second heating component includes a heating plate for contacting and heating the first membrane strip 51 and / or the second membrane strip 52. The heating plate can be disposed between the support device 4 and the cover plate 6, or the heating plate can be part of the support device 4. After being heated, the heating plate can release the adhesiveness of the first membrane strip 51 and the second membrane strip 52 and adhere to the cover plate 6 through the heat conduction of the cover plate 6. The heating plate can also be raised and lowered above the cover plate 6. After the first membrane strip 51 and the second membrane strip 52 are laid in place, the heating plate moves downward to a position close to the cover plate 6 and begins to heat the first membrane strip 51 and the second membrane strip 52 on the cover plate 6 to release their adhesiveness and adhere to the cover plate 6.

[0153] Continue to refer to Figures 10 to 15 As shown, in some embodiments, the heating mechanism further includes a heat insulation block 13, and the first heating component 11 is mounted on the transfer rack 371 via the heat insulation block 13; further, the heat insulation block 13 is disposed above the first heating component 11 and connected to the transfer rack 371; or, the heat insulation block 13 is wrapped around the outside of the first heating component 11 and connected to the transfer rack 371; the surface temperature of the heat insulation block 13 is less than or equal to 70°C, which refers to the temperature reached by the surface of the heat insulation block 13 during the operation of the heating end; with the setting of the heat insulation block 13, when the first heating component 11 needs to be replaced, there is no need to wait for the first heating component 11 to cool down, and the first heating component 11 can be replaced using the heat insulation block 13 with a lower temperature.

[0154] In some embodiments, the first heating assembly 11 further includes a heating rod 113; a heating head 112 is mounted on the heating block 111, the heating rod 113 is mounted inside the heating block 111 and used to heat the heating block 111, the heating block 111 is used to heat the heating head 112, and the heating head 112 is used to heat the film strip; specifically, the heating block 111 can be made of a high thermal conductivity material, which can quickly transfer the high temperature generated by the heating rod 113 to the heating head 112 to improve the heating efficiency of the heating head 112. This arrangement can decompose the interior of the first heating assembly 11 into multiple structures to form a modular structure, so that the heating block 111, the heating head 112 and the heating rod 113 are made of different materials and assembled to form a complete first heating assembly 11, thereby reducing the overall cost.

[0155] In a further embodiment, the first heating component 11 further includes a temperature sensor 114, which is spaced apart from the heating rod 113 on the heating block 111. The temperature sensor 114 is used to monitor the temperature of the heating block 111. Specifically, the temperature sensor 114 can be a thermocouple, which can be electrically connected to the PLC and monitor the temperature of the heating block 111 in real time. When the temperature of the heating block 111 is detected to be too high, the heating rod 113 can be powered off or the power supply parameters on the heating rod 113 can be adjusted to lower the temperature of the heating block 111. When the temperature of the heating block 111 is detected to be too low, the heating rod 113 can be powered on or the power supply parameters on the heating rod 113 can be adjusted to raise the temperature of the heating block 111. This ensures that the heating head 112 always heats the film strip within a predetermined temperature range, thereby ensuring the adhesion effect of the film strip.

[0156] Continue to refer to Figures 1 to 3 as well as Figures 16 to 18 As shown, in some embodiments, the supporting device 4 includes a conveying mechanism 41 for conveying the cover plate 6 and a straightening mechanism 42; the conveying surface of the conveying mechanism 41 forms a supporting surface; the straightening mechanism 42 is disposed on the periphery of the conveying mechanism 41 for clamping the cover plate 6 located on the supporting surface to straighten the position of the cover plate 6.

[0157] Furthermore, the straightening mechanism 42 is arranged around the periphery of the conveying mechanism 41 and is used to clamp at least two opposite sides of the cover plate 6 to straighten the cover plate 6.

[0158] In a further embodiment, the straightening mechanism 42 includes a first straightening component 421 and a second straightening component 422. The first straightening component 421 includes a first straightening member 4211 symmetrically arranged on both sides of the support surface along a first horizontal direction and a first straightening drive member 4212 for driving the first straightening members 4211 on both sides to move closer or further apart. The second straightening component 422 includes a second straightening member 4221 symmetrically arranged on both sides of the support surface along a second horizontal direction and a second straightening drive member 4222 for driving the second straightening members 4221 on both sides to move closer or further apart. The first straightening drive member 4212 and the second straightening drive member 4222 can be structures such as linear motors, cylinders, and electric cylinders. The first straightening member 4211 and the second straightening member 4221 can be columnar structures extending in a vertical direction, using their sides to push the cover plate 6.

[0159] In other embodiments, the supporting device 4 includes a conveying mechanism 41 for conveying the cover plate 6, a supporting platform 43 for supporting the cover plate 6, a platform lifting mechanism 44 for driving the supporting platform 43 to rise and fall, and a straightening mechanism 42; a supporting surface is formed on the supporting platform 43; a clearance channel is provided on the supporting platform 43 in the vertical direction to avoid the conveying mechanism 41; the straightening mechanism 42 is disposed on the periphery of the supporting platform 43 for clamping the cover plate 6 located on the supporting surface to straighten the position of the cover plate 6.

[0160] The supporting platform 43 can lift the cover plate 6 after it is delivered to the position to detach it from the conveying mechanism 41, providing stable and reliable support for the cover plate 6. The straightening mechanism 42 can correct the position of the cover plate 6 to ensure the positional accuracy of subsequent film application. The structure of the straightening mechanism 42 is the same as described above, and will not be repeated here.

[0161] Secondly, this application provides a method for applying a screen protector, comprising the following steps:

[0162] Support the cover plate 6 in the predetermined position;

[0163] A first membrane strip 51 and a second membrane strip 52 are respectively laid on the cover plate 6 located at a predetermined position. The first membrane strip 51 and the second membrane strip 52 are arranged alternately on the cover plate 6 and are perpendicular to each other.

[0164] After the first membrane strip 51 is laid, heat the first membrane strip 51 and after the second membrane strip 52 is laid, heat the second membrane strip 52 so that the first membrane strip 51 and the second membrane strip 52 release their adhesiveness and then adhere to the cover plate 6; or, after the first membrane strip 51 and the second membrane strip 52 are fully laid, heat the first membrane strip 51 and the second membrane strip 52 so that the first membrane strip 51 and the second membrane strip 52 release their adhesiveness and then adhere to the cover plate 6.

[0165] This film application method allows the cover plate 6 to complete the laying and bonding of two sets of film strips in one station, thereby improving the laying efficiency of reflective film strips on the cover plate 6. After the first film strip 51 and the second film strip 52 are laid, the first film strip 51 and / or the second film strip 52 are then bonded. This method allows the first film strip 51 and the second film strip 52 to share a set of heating mechanisms. At the same time, the bonding of the two sets of film strips can be completed in one cycle by one set of heating mechanisms, thereby significantly improving the bonding efficiency of reflective film strips and reducing the cost of the entire film application system.

[0166] In some further embodiments, after the first film strip 51 and the second film strip 52 are fully laid, heating the first film strip 51 and the second film strip 52 includes heating the intersection of the first film strip 51 and the second film strip 52 so that the first film strip 51 and the second film strip 52 simultaneously release their adhesiveness and adhere to the cover plate 6. Heating only the intersection of the first film strip 51 and the second film strip 52 can reduce the heating area while allowing the first film strip 51 and the second film strip 52 to be simultaneously adhered to the cover plate 6 with a single heating, further improving the film application efficiency.
