Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module manufacturing equipment, and in particular to a film sticking system. Background Art

[0002] In order to increase the irradiation area of sunlight on photovoltaic modules and improve the photoelectric conversion amount, many manufacturers have begun to set reflective film strips on the cover plates of photovoltaic modules. The reflective film strips can effectively reflect the sunlight passing through the gaps between the battery cells and the gaps between the battery strings onto the battery cells, thereby making full use of the sunlight irradiated on the photovoltaic modules and improving the photoelectric conversion rate.

[0003] Currently, when fixing the reflective film strips on the cover plates of photovoltaic modules, it is often necessary to first heat the first group of reflective film strips by a first heating mechanism at a first film sticking station and bond them to the set positions on the cover plates, and then convey the cover plates to a second film sticking station. At the second film sticking station, the second group of reflective film strips are heated by a second heating mechanism and bonded to the set positions on the cover plates. The second group of reflective film strips are perpendicular to the first group of reflective film strips. Since the two groups of reflective film strips on the cover plates need to be bonded at two film sticking stations respectively, the film sticking work efficiency of the cover plates is low, and this film sticking method requires two film sticking stations for the cover plates, which will further lead to a large occupied space for the equipment for sticking films on the cover plates.

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

[0035] Based on the above setting method of the third chuck and the fourth chuck, the third chuck and the fourth chuck can work in a cyclic and alternating manner to quickly and efficiently complete the transportation of the second film strip.

[0036] Optionally, the second film feeding device further includes a third connecting frame and a fourth connecting frame. The numbers of the second feeding mechanism, the third chuck, and the fourth chuck are the same as the number of the second film strips and correspond one by one; each third chuck is arranged on the third connecting frame along the first horizontal direction, the third connecting frame is drivingly connected to the third transfer assembly, each fourth chuck is arranged on the fourth connecting frame along the first horizontal direction, and the fourth connecting frame is drivingly connected to the fourth transfer assembly.

[0037] Based on the above settings of the third connecting frame and the fourth connecting frame, synchronous movement of multiple third chucks and multiple fourth chucks in the second horizontal direction can be achieved, and further multiple second film strips can be synchronously driven to move together; not only can the conveying efficiency of the second film strip be improved, but also the accuracy of the conveying positions of all the second film strips can be improved, ensuring that both ends of all the second film 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 and is used 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 settings of the transfer platform and the material transfer mechanism, the first film feeding device and the second film feeding device can be arranged on both sides of the supporting device in one direction, so that the first film feeding device can directly convey the first film strip to the cover plate. Synchronously, the second film feeding device can first convey the second film strip to the transfer platform, and then the material transfer mechanism conveys the second film strip to the cover plate after the first film strip is laid, which is convenient for the first film feeding device and the second film feeding device to synchronously prepare for the conveyance of the film strip, thereby optimizing the spatial layout and improving the efficiency.

[0040] Optionally, the material transfer mechanism includes a transfer rack, a material transfer component and a displacement component;

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

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

[0043] The material transfer component includes a picking part. The picking part is arranged below the transfer rack and is used to pick 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 form of the material transfer mechanism is provided. It picks up the second film strip through the picking part, and then drives the picking part through the displacement component to carry the second film strip.

[0045] Optionally, the heating mechanism is arranged below the transfer rack, and the picking part can approach or move away from the transfer rack in the vertical direction;

[0046] When the picking part moves in the direction away from the transfer rack to the first position, it is lower than the heating end of the heating mechanism; when the picking part moves in the direction close to the transfer rack to the second position, it is flush with the heating end of the heating mechanism.

[0047] By jointly arranging the heating mechanism and the picking part on the material transfer rack and enabling the picking part to approach or move away from the material transfer rack in the vertical direction, when it is necessary to pick up the film strip, first place the picking part at the first position so that the picking part is lower than the heating end of the heating mechanism. After the displacement assembly drives the material transfer rack to descend and approach the second film strip, the picking part can pick up the film strip. After the picking part places the picked second film strip on the cover plate, the displacement assembly drives the material transfer rack to descend, and at the same time, moves the picking part in the direction close to the material transfer rack to the second position so that the picking part 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 the film strip to bond the film strip to the cover plate. It can be seen that the present application can simultaneously realize the handling of the second film strip and the heating and bonding of the first film strip and / or the second film strip, which not only reduces the equipment cost, but also improves the fluency of handling the reflective film strip and heating and bonding the reflective film strip, and improves the bonding efficiency of the reflective film strip.

[0048] Optionally, the heating mechanism further includes a third pressing assembly connected to the material transfer rack, and the third pressing assembly is at least used to press the first film strip and / or the second film strip when the heating end of the heating mechanism moves away from the first film strip and / or the second film strip.

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

[0050] Optionally, the number of the second film feeding devices is two groups, and the two groups of second film feeding devices are arranged oppositely in the second horizontal direction. The two groups of second film feeding devices respectively transport the two groups of second film strips to the cover plate located on the support surface so that the two groups of second film strips are respectively located in the first half and the second half arranged along the second horizontal direction on the cover plate.

[0051] Based on the above-mentioned second film feeding device, when it is necessary to lay two groups of second film strips on the first half and the second half in the second horizontal direction of the cover plate respectively, at this time, the second film feeding device is correspondingly set to two groups, and the simultaneous transportation of the two groups of second film strips can be realized, thereby improving the laying efficiency of the reflective film strips on the cover plate.

[0052] Optionally, the heating mechanism includes a plurality of first heating components, and each first heating component is used to perform point heating on the first film strip and / or the second film strip so that the first film strip and the second film strip release viscosity and bond to the cover plate;

[0053] Or,

[0054] The heating mechanism includes at least one second heating component, and the second heating component is used to perform surface heating on the first film strip and / or the second film strip so that the first film strip and the second film strip release viscosity and bond to the cover plate.

[0055] Based on the above heating mechanism, 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 position of the first film strip and the second film strip correspondingly, so that the first film strip and the second film strip release adhesiveness simultaneously and adhere to the cover plate.

[0057] Based on the fact that the first heating component only heats the intersection position of the first film strip and the second film strip, while reducing the heating area, the first film strip and the second film strip can be adhered to the cover plate simultaneously through one-time heating, further improving the film sticking efficiency.

[0058] Optionally, the first heating component includes a heating block and a dotting iron; the dotting iron is installed on the heating block, the heating block is used to heat up the dotting iron, and the dotting iron is used to dot the first film strip and / or the second film strip;

[0097] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0098] Currently, when attaching reflective film strips to the cover of a photovoltaic module, a first heating mechanism is often used at a first laminating station to heat and bond the first set of reflective film strips to the designated locations on the cover. The cover is then transported to a second laminating station, where a second heating mechanism is used to heat and bond the second set of reflective film strips to the designated locations on the cover, with the second set of reflective film strips perpendicular to the first set. Because the two sets of reflective film strips on the cover need to be bonded separately at two laminating stations, the efficiency of laminating the cover is low. Furthermore, this laminating method requires two laminating stations for the cover, which in turn results in a large space requirement for the equipment used to laminarize the cover.

[0099] Based on this, the present application provides a film pasting system, which, through the setting of a supporting device, can provide reliable and stable support to the cover plate during the process of bonding the reflective film strips, thereby improving the bonding reliability and accuracy of the reflective film strips, and the first film feeding device and the second film feeding device both feed the film strips to the cover plate located on the supporting surface of the supporting device. There is no need to feed the cover plate, and the first film strips and the second film strips that are perpendicular to each other can be bonded to the cover plate at the same supporting surface using a set of heating mechanisms. Compared with the existing film pasting equipment that requires two film pasting stations, the film pasting system of the present application can not only improve the bonding efficiency, but also streamline the mechanism settings in the entire film pasting system, reduce costs, and reduce the space occupied by the entire film pasting system.

[0100] The present application will be described in detail below through specific embodiments.

[0101] First, refer to Figures 1 to 18As shown in the figure, this embodiment provides a film pasting 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 the cover plate 6; the first film feeding device 2 is used to convey a first film strip 51 extending along the first horizontal direction to the cover plate 6 located on the supporting surface, and the second film feeding device 3 is used to convey a second film strip 52 extending along the second horizontal direction to the cover plate 6 located on the supporting surface. The first film strip 51 and the second film strip 52 are arranged in a staggered manner 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 viscosity and then adhere to the cover plate 6.

[0102] Optionally, the first film strip 51 and the second film strip 52 can be laid on the cover plate 6 in a set manner first, and then the heating of the first film strip 51 and the second film strip 52 can be completed by a set of heating mechanisms. Or the first film strip 51 can be laid on the set position of the cover plate 6 first, and then the heating of the first film strip 51 can be completed by the heating mechanism. Then the second film strip 52 can be laid on the set position of the cover plate 6, and finally the heating of the second film strip 52 can be completed by the previous heating mechanism.

[0103] In the film pasting system provided in this embodiment, through the setting of the supporting device 4, reliable and stable support can be provided for the cover plate 6 during the process of adhering the reflective film strips, improving the adhesion reliability and accuracy of the reflective film strips. Moreover, both the first film feeding device 2 and the second film feeding device 3 convey film strips to the cover plate 6 located on the supporting surface of the supporting device 4, without the need to convey the cover plate 6. The mutually perpendicular first film strip 51 and second film strip 52 can complete the work of adhering to the cover plate 6 at the same supporting surface by using a set of heating mechanisms. Compared with the existing film pasting equipment that requires two film pasting stations, the film pasting system of this application can not only improve the adhesion efficiency, but also streamline the mechanism settings in the entire film pasting system, reduce costs, and also reduce the occupied space of the entire film pasting system.

[0104] Continue to refer to Figures 1 to 4As 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, the first film pulling mechanism 22 includes a first chuck 221 for clamping the first end of the first film strip 51 and a second chuck 222 for clamping the second end of the first film strip 51. The first end of the first film strip 51 can be the head end or the tail end of the first film strip 51; the first displacement mechanism includes a first transfer component drivingly connected to the first chuck 221 and a second transfer component drivingly connected to the second chuck 222; the first transfer component is used to drive the first chuck 221 to move in the first horizontal direction and the vertical direction; the second transfer component is used to drive the second chuck 222 to move in the first horizontal direction and the vertical direction; wherein, the first transfer component and the second transfer component can be one or a combination of a conveyor belt, a conveyor chain, an electric cylinder, a cylinder, and a linear motor.

[0105] Through the settings of 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 are realized, and the first film strip 51 can be transferred from the first feeding mechanism 21 to the set position on the cover plate 6 to complete the transportation work of the first film strip 51.

[0106] Optionally, the first feeding mechanism 21 can pre-store the first film strip 51 with a predetermined length. Through the setting of the first feeding mechanism 21, the first film pulling mechanism 22 can always remove the first film strip 51 from the same position of the first feeding mechanism 21, thereby simplifying the movement mode of the first displacement mechanism and reducing the overall cost.

[0107] Optionally, the first feeding mechanism 21 can also be used to supply a continuous film strip, and then the continuous film strip is cut into the first film strip 51 with a predetermined length by cutting. At this time, the first film feeding device 2 further 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 strip 51. Optionally, the first feeding mechanism 21 can include a reel for winding the first film strip 51 and a motor for driving the reel to rotate. A plurality of guide wheels can be arranged between the reel and the discharging position to apply a pre-tightening force to the first film strip 51 to ensure that the first film strip 51 can be conveyed along the set route.

[0108] Among them, one of the first chuck 221 and the second chuck 222 is used to clamp the free end of the first film strip 51 and pull out the first film strip 51 by a predetermined length; between the other of the first chuck 221 and the second chuck 222 and the first feeding mechanism 21, a first pressing assembly 23 and a first cutting assembly 24 are sequentially arranged along the pulling direction of the first film strip 51; the first pressing assembly 23 and the other of the first chuck 221 and the second chuck 222 are respectively used to fix the first film strip 51 after the first film strip 51 is pulled out by a predetermined length, and the first cutting assembly 24 is used to cut off the first film strip 51.

[0109] Through the arrangement of the first pressing assembly 23 and the first cutting assembly 24, it can cooperate with the first chuck 221 or the second chuck 222 to first pull out the free end of the first film strip 51 by a set length, and then at the tail end position of the first film strip 51, clamp and fix the front and rear sides of the tail end of the first film strip 51 by using the first chuck 221 or the second chuck 222 and the first pressing assembly 23 respectively, and then use the first cutting assembly 24 to cut at the tail end position between the two, so as to process the first film strip 51 with a predetermined length.

[0110] In a further embodiment, the first chuck 221 and the second chuck 222 are configured to alternately clamp the free end of the first film strip 51 and pull out the first film strip 51 by a predetermined length; that is to say, the first chuck 221 can be used to clamp the free end of the first film strip 51 and pull out the first film strip 51 by a predetermined length. At this time, the second chuck 222 clamps the tail end of the first film strip 51. Through the synchronous movement of the first chuck 221 and the second chuck 222, the first film strip 51 is transported in place. After the transportation of the first film strip 51 is completed, at this time, the second film strip 52 only needs to move a short distance, and clamp the free end of the next first film strip 51, continue to pull out the next first film strip 51 by a predetermined length, and then the first chuck 221 moves to the discharging position of the first feeding mechanism 21 and clamps the tail end of the next first film strip 51, and continues to complete the transportation of the next first film strip 51 in place through the synchronous movement of the second chuck 222 and the first chuck 221. Similarly, complete the transportation work of the third, fourth, etc. first film strips 51; in the whole process, the first chuck 221 and the second chuck 222 work in a cyclic and alternating manner, and quickly and efficiently complete the transportation work of two or more first film strips 51.

[0111] Continue to refer to Figure 3 and Figure 8As shown in the figure, further, the first film feeding device 2 further includes a first connecting frame 251 and a second connecting frame. The numbers of the first feeding mechanism 21, the first clamping heads 221, and the second clamping heads 222 are the same as and correspond one by one to the number of the first film strips 51. Each of the first clamping heads 221 is arranged on the first connecting frame 251 along the second horizontal direction. The first connecting frame 251 is drivingly connected to the first transfer assembly. Each of the second clamping heads 222 is arranged on the second connecting frame along the second horizontal direction. The second connecting frame is drivingly connected to the second transfer assembly. That is to say, through the settings of the first connecting frame 251 and the second connecting frame, synchronous movement of multiple first clamping heads 221 and multiple second clamping heads 222 in the first horizontal direction can be realized, so as to synchronously drive multiple first film strips 51 to be laid on the cover plate 6 together. It can not only improve the conveying efficiency of the first film strips 51, but also improve the accuracy of the conveying positions of all the first film strips 51, and ensure that both ends of all the first film strips 51 are flush in the second horizontal direction.

[0112] 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. The second film pulling mechanism 32 includes a third clamping head 321 for clamping the first end of the second film strip 52 and a fourth clamping head 322 for clamping the second end of the second film strip 52. The first end of the second film strip 52 can be the head end or the tail end of the second film strip 52. The second displacement mechanism includes a third transfer assembly drivingly connected to the third clamping head 321 and a fourth transfer assembly drivingly connected to the fourth clamping head 322. The third transfer assembly is used to drive the third clamping head 321 to move along the second horizontal direction and the vertical direction. The fourth transfer assembly is used to drive the fourth clamping head 322 to move along the second horizontal direction and the vertical direction. Among them, the third transfer assembly and the fourth transfer assembly can be a combination of one or more of a conveyor belt, a conveyor chain, an electric cylinder, a cylinder, and a linear motor.

[0113] Through the settings of the second feeding mechanism 31, the second film pulling mechanism 32, and the second displacement mechanism, on-line supply and handling of the second film strip 52 are realized, and the second film strip 52 can be transferred from the second feeding mechanism 31 to a set position on the cover plate 6 to complete the transportation work of the second film strip 52.

[0114] Optionally, the second feeding mechanism 31 can pre-store the second film strip 52 with a predetermined length. Through the setting of the second feeding mechanism 31, the second film pulling mechanism 32 can always carry 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.

[0115] Optionally, the second feeding mechanism 31 can also be used to supply a continuous film strip, and then the continuous film strip is cut into a second film strip 52 with a predetermined length by cutting. At this time, the second film feeding device 3 further includes a second pressing assembly 33 and a second cutting assembly 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 reel for winding the second film strip 52 and a motor for driving the reel to rotate. A plurality of guide wheels can be arranged between the reel and the discharging position to apply a pre-tightening force to the second film strip 52 to ensure that the second film strip 52 can be conveyed along the set route.

[0116] Optionally, one of the third chuck 321 and the fourth chuck 322 is used to clamp the free end of the second film strip 52 and pull out the second film strip 52 by a predetermined length; between the other of the third chuck 321 and the fourth chuck 322 and the second feeding mechanism 31, a second pressing assembly 33 and a second cutting assembly 34 are sequentially arranged along the pulling direction of the second film strip 52; the second pressing assembly 33 and the other of the third chuck 321 and the fourth chuck 322 are respectively used to fix the second film strip 52 after the second film strip 52 is pulled out by a predetermined length, and the second cutting assembly 34 is used to cut off the second film strip 52.

[0117] Through the arrangement of the second pressing assembly 33 and the second cutting assembly 34, it can cooperate with the third chuck 321 or the fourth chuck 322 to first pull out the free end of the second film strip 52 by a set length, and then at the tail end position of the second film strip 52, clamp and fix the front and rear sides of the tail end of the second film strip 52 by using the third chuck 321 or the fourth chuck 322 and the second pressing assembly 33 respectively, and then use the second cutting assembly 34 to cut at the tail end position between the two, so as to process the second film strip 52 with a predetermined length.

[0118] Further, the third chuck 321 and the fourth chuck 322 are configured to alternately clamp the free end of the second film strip 52 and pull out the second film strip 52 by a predetermined length; that is, the third chuck 321 can be first used to clamp the free end of the second film strip 52, and the second film strip 52 is pulled out by a predetermined length. At this time, the fourth chuck 322 clamps the tail end of the second film strip 52. Through the synchronous movement of the third chuck 321 and the fourth chuck 322, the second film strip 52 is transported in place. After the transportation of the second film strip 52 is completed, at this time, the second film strip 52 only needs to move a short distance, and the free end of the next second film strip 52 is clamped, and the next second film strip 52 is pulled out by a predetermined length. Then, the third chuck 321 moves to the discharging position of the second feeding mechanism 31 and clamps the tail end of the next second film strip 52. Continuing through the synchronous movement of the fourth chuck 322 and the third chuck 321, the transportation of the next second film strip 52 is completed in place. Similarly, the transportation of the third, fourth, etc. second film strips 52 is completed; in the whole process, the third chuck 321 and the fourth chuck 322 work in a cyclic and alternating manner, quickly and efficiently completing the transportation of two or more second film strips 52.

[0119] In some embodiments, the second film feeding device 3 further includes a third connecting frame 351 and a fourth connecting frame. The numbers of the second feeding mechanism 31, the third chuck 321, and the fourth chuck 322 are the same as and correspond one-to-one to the number of the second film strips 52; each third chuck 321 is arranged on the third connecting frame 351 along the first horizontal direction, and the third connecting frame 351 is drivingly connected to the third transfer assembly. Each fourth chuck 322 is arranged on the fourth connecting frame along the first horizontal direction, and the fourth connecting frame is drivingly connected to the fourth transfer assembly. That is to say, through the settings of the third connecting frame 351 and the fourth connecting frame, the synchronous movement of multiple third chucks 321 and multiple fourth chucks 322 in the second horizontal direction can be realized, thereby synchronously driving multiple second film strips 52 to move together; not only can the conveying efficiency of the second film strips 52 be improved, but also the accuracy of the conveying positions of all the second film strips 52 can be improved, ensuring that both ends of all the second film strips 52 are flush in the first horizontal direction.

[0120] Continue to refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown in, the second film feeding device 3 further includes a transfer platform 36 and a material transfer mechanism 37. The transfer platform 36 extends along the 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 material 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 the second film strips 52 is less than the number of the first film strips 51, so as to reduce the structural complexity of the transfer platform 36 and the material transfer mechanism 37.

[0121] Since the first film strip 51 and the second film strip 52 are perpendicular to each other, based on the above settings of the transfer platform 36 and the material transfer mechanism 37, the first film feeding device 2 and the second film feeding device 3 can be arranged on both sides of the supporting device 4 in the same direction. In this way, the first film feeding device 2 can directly feed the first film strip 51 onto the cover plate 6. Synchronously, the second film feeding device 3 can first feed the second film strip 52 onto the transfer platform 36, and then the material transfer mechanism 37 feeds the second film strip 52 onto the cover plate 6 after the first film strip 51 is laid. This facilitates the preparation work before the film strips are fed synchronously by the first film feeding device 2 and the second film feeding device 3, thereby optimizing the spatial layout and improving efficiency.

[0122] In some embodiments, a plurality of adsorption hole groups are arranged at intervals along the first horizontal direction on the transfer platform 36. Each adsorption hole group includes a plurality of adsorption holes arranged at intervals along the second horizontal direction. Each adsorption hole group is used to correspondingly adsorb a second film strip 52 to implement the positioning of each second film strip 52 laid on the transfer platform 36.

[0123] Among them, the material transfer mechanism 37 includes a transfer frame 371, a material transfer component 372, and a displacement component 373; the transfer platform 36 is arranged on one side of the supporting device 4 along the first horizontal direction; the displacement component 373 is drivingly connected to the transfer frame 371 and is used to drive the transfer frame 371 to lift and translate along the first horizontal direction; the material transfer component 372 includes a picking part 3721. The picking part 3721 is arranged below the 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.

[0124] Optionally, the picking part 3721 can be a suction cup communicated with a gas source. The suction cup adsorbs and fixes the second film strip 52 by forming a negative pressure, and can also make the second film strip 52 detach from it by releasing the negative pressure.

[0125] Optionally, there are a plurality of transfer frames 371. The material transfer component 372 includes a plurality of picking parts 3721. A plurality of picking parts 3721 are arranged along the second horizontal direction on each transfer frame 371. The plurality of picking parts 3721 on each transfer frame 371 are used to cooperate to pick up a second film strip 52.

[0126] In some embodiments, the displacement component 373 can include a track 3731 extending along the first horizontal direction and a plurality of lifting driving parts 3734. The lifting driving parts 3734 are slidably arranged on the track 3731 along the first horizontal direction. The movable ends of the lifting driving parts 3734 are correspondingly connected to the transfer frame 371 and are used to drive the transfer frame 371 to lift.

[0127] Furthermore, the displacement component 373 further includes a spacing structure, which includes a spacing driving part 3732 and movers 3733 connected to the lifting driving members 3734 in a one-to-one correspondence. Each mover 3733 is arranged on the track 3731, and the spacing driving part 3732 is used to drive each mover 3733 to slide in the first horizontal direction, so that a set distance is provided between any two adjacent material transfer racks 371. Therefore, after all the material transfer racks 371 move along the first horizontal direction through the spacing component, the distance between every two material transfer racks 371 can be made the same. By providing the spacing structure, the distance between the second film strips 52 on the transfer platform 36 can be set to be smaller than the distance between the second film strips 52 to be laid on the cover plate 6, thereby reducing the size and floor space of the transfer platform 36. After the material transfer mechanism 37 picks up the second film strips 52 from the transfer platform 36, the spacing of the second film strips 52 can be implemented during the handling process of the second film strips 52, so that all the second film strips 52 are uniformly arranged on the cover plate 6 according to the set positions.

[0128] In some embodiments, the heating mechanism is arranged below the material transfer rack 371, and the picking part 3721 can move closer to or away from the material transfer rack 371 in the vertical direction. When the picking part 3721 moves in the direction away from the material transfer rack 371 to the first position, it is lower than the heating end of the heating mechanism. When the picking part 3721 moves in the direction close to the material transfer rack 371 to the second position, it is flush with the heating end of the heating mechanism.

[0129] Among them, by arranging the heating mechanism and the picking part 3721 on the material transfer rack 371 together and enabling the picking part 3721 to move closer to or away from the material transfer rack 371 in the vertical direction, when it is necessary to pick up the film strip, first make the picking part 3721 in the first position, so that the picking part 3721 is lower than the heating end of the heating mechanism. After the displacement component 373 drives the material transfer rack 371 to descend and approach the second film strip 52, the picking part 3721 can pick up the film strip. After the picking part 3721 places the picked second film strip 52 on the cover plate 6, the displacement component 373 drives the material transfer rack 371 to descend, and at the same time makes the picking part 3721 move in the direction close to the material transfer rack 371 to the second position, so that the picking 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 the film strip to bond the film strip to the cover plate 6. It can be seen that the present 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 the equipment cost, but also improves the smoothness of handling the reflective film strip and heating and bonding the reflective film strip, and improves the bonding efficiency of the reflective film strip.

[0130] Optionally, the picking part 3721 is mounted on the material transfer rack 371 so as to be vertically movable by a spring. When the spring is in its natural state, the picking part 3721 moves to the first position; the lifting drive member 3734 drives the material transfer rack 371 to descend, and at the same time makes the picking part 3721 move towards the direction close to the material transfer rack 371 to the second position. When the picking part 3721 is flush with the heating end of the heating mechanism, the spring is in a compressed state.

[0131] Optionally, the heating mechanism further includes a third pressing assembly connected to the material transfer rack 371. The third pressing assembly is at least used to press 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.

[0132] Further, the third pressing assembly includes a pressing structure 12. The pressing structure 12 includes an elastic connecting member 121 and a pressing block 122. The elastic connecting member 121 can elastically deform in the vertical direction. The pressing block 122 is connected to the material transfer rack 371 through the elastic connecting member 121. The bottom of the pressing block 122 forms a pressing surface for pressing the film strip. When the elastic connecting member 121 is in its natural state, the pressing surface is lower than the heating end of the heating mechanism.

[0133] The optional working process of the third pressing assembly in the above embodiment is as follows: the material transfer rack 371 drives the third pressing assembly and the heating end of the heating mechanism to descend. Since the elastic connecting member 121 is in its natural state and the pressing surface is lower than the heating end, the pressing surface first contacts the film strip; as the material transfer rack 371 continues to descend, while the pressing block 122 presses the film strip, the elastic connecting member 121 is compressed. After the elastic connecting member 121 is compressed by a certain length, the heating end on the heating assembly starts to contact the film strip and starts 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.

[0134] After the film strip is heated, the material transfer rack 371 drives the third pressing assembly and the heating end of the heating mechanism to rise. Among them, the heating end first leaves the film strip, and the pressing block 122 can maintain the pressing on the film strip under the action of the elastic connecting member 121 until the elastic connecting member 121 returns to its natural state, and the pressing block 122 begins to disengage from the film strip. Thus, even if the film strip adheres to the heating end, the film strip will not be lifted by the heating end when the heating end leaves the film strip, ensuring the connection reliability between the film strip and the cover plate 6.

[0135] Further, there is one pressing block 122, and a through hole 123 for the heating end to pass through is provided on the pressing block 122; or, there are at least two pressing blocks 122, and the pressing blocks 122 are arranged at intervals along the circumference of the heating end, and an avoidance space for avoiding the heating end is formed between the pressing blocks 122. The heating end is used to pass through the avoidance space to heat the film strip.

[0136] Optionally, the elastic connecting member 121 includes a guide post and a spring sleeved on the guide post. The pressing block 122 is movably mounted on the material transfer rack 371 through the guide post. The upper end of the spring abuts against the material transfer rack 371, and the lower end abuts against the pressing block 122.

[0137] Continuing to refer to Figure 1 and Figure 2 As shown, in some embodiments, the number of the second film feeding devices 3 is two groups. The two groups of second film feeding devices 3 are oppositely arranged in the second horizontal direction. The two groups of second film feeding devices 3 respectively transport the two groups of second film strips 52 to the cover plate 6 located on the supporting surface, so that the two groups of second film strips 52 are respectively located on the first half and the second half arranged along the second horizontal direction on the cover plate 6.

[0138] When it is necessary to respectively lay two groups of second film strips 52 on the first half and the second half in the second horizontal direction of the cover plate 6, at this time, the second film feeding device 3 is correspondingly set to two groups, and the simultaneous transportation of the two groups of second film strips 52 can be realized, improving the laying efficiency of the reflective film strips on the cover plate 6.

[0139] In some embodiments, the heating mechanism includes a plurality of first heating components 11. Each first heating component 11 is used to perform spot 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 viscosity and adhere to the cover plate 6, avoiding the entire surface of the cover plate 6 from being heated. It can not only ensure that the first film strip 51 and the second film strip 52 are smoothly adhered to the cover plate 6, but also effectively reduce the deformation of the cover plate 6; alternatively, the heating mechanism includes at least one second heating component, and the second heating component is 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 viscosity and adhere to the cover plate 6.

[0140] Furthermore, each first heating component 11 is used to correspondingly heat the intersection position 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 release viscosity simultaneously and adhere to the cover plate 6. The first heating component 11 only performs heating on the intersection position 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 be adhered to the cover plate 6 simultaneously through one heating, further improving the film sticking efficiency.

[0141] In some embodiments, both ends of each first film strip 51 intersect with the second film strip 52, and both ends of each second film strip 52 intersect with the first film strip 51; the first heating component 11 of the heating mechanism is at least used to heat the intersection positions at both ends of each first film strip 51 and the intersection positions at both ends of each second film strip 52.

[0142] By heating at least the intersection positions at both ends of each first film strip 51 and the intersection positions at both ends of each second film strip 52, it is ensured that at least the two end positions of each reflective film strip can be bonded to the cover plate 6, thus ensuring the connection reliability between the reflective film strip and the cover plate 6.

[0143] The first heating assembly 11 is further configured to heat at least one intersection position in the middle of each first film strip 51 and at least one intersection position in the middle of each second film strip 52.

[0144] It should be noted that the middle of the first film strip 51 refers to any position between the two ends of the first film strip 51; the middle of the second film strip 52 refers to any position between the two ends of the second film strip 52; such a design can further increase the connection point positions between the first film strip 51 and the second film strip 52 and the cover plate 6, thereby improving the bonding reliability between the first film strip 51 and the second film strip 52 and the cover plate 6.

[0145] Continue to refer to Figures 9 to 15 As shown, the first heating assembly 11 includes a heating block 111 and a dotting iron 112; the dotting iron 112 is installed on the heating block 111, the heating block 111 is used to heat up the dotting iron 112, and the dotting iron 112 is used to dot the first film strip 51 and / or the second film strip 52. Among them, the dotting iron 112 can move relative to the heating block 111 in the vertical direction, the dotting iron 112 can be connected to the heating block 111 through an elastic member, or the dotting iron 112 can also be fixedly installed on the heating block 111; alternatively, the second heating assembly is an infrared lamp box, and the infrared lamp box is used to irradiate and heat the first film strip 51 and / or the second film strip 52. Optionally, the infrared lamp box can be arranged above the supporting device 4. After the first film strip 51 and the second film strip 52 are both laid in place, the first film strip 51 and the second film strip 52 on the cover plate 6 are irradiated to make them release adhesiveness and bond to the cover plate 6; alternatively, the second heating assembly includes a heating plate, and the heating plate is used to contact and heat the first film strip 51 and / or the second film strip 52. Among them, the heating plate can be arranged between the supporting device 4 and the cover plate 6, or rather, the heating plate can be part of the supporting device 4. After the heating plate is heated, the first film strip 51 and the second film strip 52 can release adhesiveness and bond to the cover plate 6 through the heat conduction of the cover plate 6. The heating plate can also be arranged above the cover plate 6 in a liftable manner. After the first film strip 51 and the second film strip 52 are both laid in place, the heating plate moves downward to a position close to the cover plate 6 and starts to heat the first film strip 51 and the second film strip 52 on the cover plate 6 to make them release adhesiveness and bond to the cover plate 6.

[0146] Continue to refer to Figures 10 to 15As shown, in some embodiments, the heating mechanism further includes a heat insulation block 13. The first heating assembly 11 is mounted on the material transfer rack 371 through the heat insulation block 13. Further, the heat insulation block 13 is disposed above the first heating assembly 11 and connected to the material transfer rack 371. Alternatively, the heat insulation block 13 wraps around the outer side of the first heating assembly 11 and is connected to the material transfer rack 371. The surface temperature of the heat insulation block 13 is less than or equal to 70 °C, and this surface temperature refers to the temperature reached by the surface of the heat insulation block 13 during the operation of the heating end. Through the setting of the heat insulation block 13, when the first heating assembly 11 needs to be replaced, it is not necessary to wait for the first heating assembly 11 to cool down, and the first heating assembly 11 can be replaced by using the relatively low-temperature heat insulation block 13.

[0147] In some embodiments, the first heating assembly 11 further includes a heating rod 113. The spot iron 112 is mounted on the heating block 111. The heating rod 113 is mounted inside the heating block 111 and is used to heat up the heating block 111. The heating block 111 is used to heat up the spot iron 112. The spot iron 112 is used for spot ironing 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 spot iron 112 to improve the heating efficiency of the spot iron 112. Such a setting can decompose the internal part of the first heating assembly 11 into multiple structures to form a modular structure, so that the heating block 111, the spot iron 112 and the heating rod 113 are made of different materials respectively and assembled to form a complete first heating assembly 11, thereby reducing the overall cost.

[0148] In a further embodiment, the first heating assembly 11 further includes a temperature sensor 114. The temperature sensor 114 and the heating rod 113 are spaced apart on the heating block 111. The temperature sensor 114 is used to monitor the temperature of the heating block 111. The temperature sensor 114 can specifically be a thermocouple, which can be electrically connected to the PLC and monitor the temperature of the heating block 111 in real time. When it is detected that the temperature of the heating block 111 is too high, the heating rod 113 can be controlled to cut off the power or the power-on parameters of the heating rod 113 can be adjusted to lower the temperature of the heating block 111. When it is detected that the temperature of the heating block 111 is too low, the heating rod 113 can be controlled to be powered on or the power-on parameters of the heating rod 113 can be adjusted to raise the temperature of the heating block 111, so as to ensure that the spot iron 112 always heats the film strip within a predetermined temperature range, and further ensure the bonding effect of the film strip.

[0149] Continue to refer to Figures 1 to 3 and 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 rectifying mechanism 42. The conveying surface of the conveying mechanism 41 forms a supporting surface. The rectifying mechanism 42 is disposed on the periphery of the conveying mechanism 41 and is used to clamp the cover plate 6 located on the supporting surface to correct the position of the cover plate 6.

[0150] Further, the rectifying mechanism 42 is disposed around the conveying mechanism 41 and is used for clamping at least two opposite sides of the cover plate 6 to rectify the cover plate 6.

Among them, the structure of the rectifying mechanism 42 is the same as that described above and will not be elaborated here one by one.

[0154] In a second aspect, the present application provides a film pasting method, including the following steps:

[0155] Support the cover plate 6 at a predetermined position;

[0156] Lay a first film strip 51 and a second film strip 52 on the cover plate 6 located at the predetermined position respectively. The first film strip 51 and the second film strip 52 are arranged in an alternating manner on the cover plate 6, and the first film strip 51 and the second film strip 52 are perpendicular to each other;

[0157] After the laying of the first film strip 51 is completed, heat the first film strip 51, and after the laying of the second film strip 52 is completed, heat the second film strip 52, so that the first film strip 51 and the second film strip 52 release their adhesiveness and then bond to the cover plate 6; alternatively, after the laying of the first film strip 51 and the second film strip 52 is all completed, heat the first film strip 51 and the second film strip 52, so that the first film strip 51 and the second film strip 52 release their adhesiveness and then bond to the cover plate 6.

[0158] Through this film pasting method, it is possible to complete the laying and bonding of two groups of film strips on the cover plate 6 at one station, thereby improving the laying efficiency of the reflective film strips on the cover plate 6. After the laying of the first film strip 51 and the second film strip 52, then bond the first film strip 51 and / or the second film strip 52. This method can enable the first film strip 51 and the second film strip 52 to share a set of heating mechanisms. At the same time, it is also possible to complete the bonding of two groups of film strips through one cycle of operation of a set of heating mechanisms, thereby significantly improving the bonding efficiency of the reflective film strips and reducing the cost of the entire film pasting system.

[0159] In some further embodiments, heating the first film strip 51 and the second film strip 52 after the laying of the first film strip 51 and the second film strip 52 is all completed includes: heating the intersection position of the first film strip 51 and the second film strip 5 , so that the first film strip 51 and the second film strip 52 release their adhesiveness simultaneously and then bond to the cover plate 6. Only heating the intersection position of the first film strip 51 and the second film strip 52 can reduce the heating area while enabling the first film strip 51 and the second film strip 52 to be bonded to the cover plate 6 simultaneously through one heating, further improving the film pasting efficiency.
