Guard frame, single layer laminator and multi-layer laminator

Abstract

The application provides a protective frame, a single-layer laminating machine and a multi-layer laminating machine. The protective frame can be hung below the top cover of the single-layer laminating machine or below the top cover or laminating unit of the multi-layer laminating machine to protect the edges of the laminated photovoltaic module during lamination. The protective frame comprises a rectangular frame and N bars. The frame is composed of two first frames extending in a first direction and two second frames extending in a second direction. The two ends of the bars are connected to the two first frames respectively. The protective space for the photovoltaic module is formed between the adjacent two bars and between the second frame adjacent to the Nth bar and the Nth bar. When the single-layer laminating machine and the multi-layer laminating machine are closed, the protective frame automatically falls down and automatically covers the photovoltaic module below. When the lamination is completed and the cover is opened, the protective frame automatically separates from the photovoltaic module, and manual handling of the protective frame for feeding and discharging is not needed, thereby improving the lamination efficiency.

Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, specifically a protective frame, a single-layer laminator, and a multi-layer laminator. Background Technology

[0002] Lamination is an important step in the production of photovoltaic modules, and it is accomplished using single-layer or multi-layer laminators.

[0003] A single-layer laminator typically includes a top cover and a base located below the top cover. The outer periphery of the base is covered with a high-temperature cloth that can operate, which can support the photovoltaic modules on the base. After the single-layer laminator is closed, the top cover and the base come together, and the pressure plate in the top cover can laminate the photovoltaic modules on the base.

[0004] A multilayer laminator typically includes a top cover, multilayer laminator units, and a base arranged sequentially from top to bottom. The base is covered with a high-temperature cloth that can move around. The high-temperature cloth can support the photovoltaic modules on the base. Each laminator unit can also support the photovoltaic modules. After the multilayer laminator is closed, the top cover, multilayer laminator units, and base come together and can perform lamination on the photovoltaic modules on the laminator units and the base.

[0005] When laminating photovoltaic (PV) modules, to ensure even stress distribution and prevent excessive pressure on the edges, which could damage them, the current method involves manually placing a rectangular protective frame on each PV module before it enters the laminator (single or multi-layer). The PV module, along with the protective frame, enters the laminator together. The laminator's pressure plates press down on the PV module and protective frame, achieving lamination. During lamination, the protective frame supports the pressure plates, preventing excessive pressure on the edges of the PV module and thus protecting them. After lamination is complete, the protective frame is manually removed.

[0006] However, applying and removing protective frames to each photovoltaic module is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0007] To address the aforementioned technical problems, this application provides a protective border, the detailed technical solution of which is as follows:

[0008] A protective frame is suspended below the top cover of a single-layer laminator, or below the top cover or lamination unit of a multi-layer laminator, to protect the edges of the laminated photovoltaic modules during lamination. The protective frame includes:

[0009] The rectangular frame is composed of two first side borders extending along a first direction and two second side borders extending along a second direction, connected end to end, with the second direction perpendicular to the first direction.

[0010] N baffles are arranged at intervals along the first direction and extend along the second direction. The two ends of the baffles are connected to the two first frame members respectively. A protective space is formed between two adjacent baffles and between the second frame member adjacent to the Nth baffle and the Nth baffle. Each protective space is used to house a photovoltaic module.

[0011] The protective frame provided in this application can be suspended below the top cover of a single-layer laminator, or suspended below the top cover or lamination unit of a multi-layer laminator.

[0012] When the single-layer or multi-layer laminator is closed, the protective frame automatically falls and fits onto the photovoltaic module below, driven by the top cover or lamination unit. When the lamination is completed and the cover is opened, the protective frame automatically detaches from the photovoltaic module, driven by the top cover or lamination unit. There is no need for manual handling of the protective frame for loading and unloading, which saves labor and improves the lamination production efficiency of photovoltaic modules.

[0013] In some embodiments, the protective frame includes 4N baffles; the 4N baffles extend along a first direction, and baffles are provided at the four corners of each protective space, wherein: of the four baffles in the i-th protective space, two are provided on the i-th baffle and the other two are provided on the (i+1)-th baffle. Of the four baffles in the N-th protective space, two are provided on the N-th baffle and the other two are provided on the second frame adjacent to the N-th baffle; N≥2, 1≤i<N.

[0014] Since each protective space has baffles at its four corners, during the lamination process, the four baffles can work with the baffles or the second frame to protect the four corners of the photovoltaic module, preventing stress accumulation at the four corners of the photovoltaic module from causing damage.

[0015] In some embodiments, the two ends of the stop lever are respectively adjustablely connected to two first side frames, and the stop lever can move along the first side frames to perform position adjustment in a first direction; the stop bar is adjustablely connected to the corresponding stop lever or second side frame, and the stop bar can move along the stop lever or second side frame to perform position adjustment in a second direction.

[0016] By adjusting the position of the baffle in the first direction and the position of the baffle in the second direction, the protective space can be made compatible with photovoltaic modules of different sizes, thereby improving the versatility of this application.

[0017] In some embodiments, the baffle is arbitrarily connected to the baffle bar or the second frame via a first right-angle member; the first right-angle member includes a first connecting portion extending in a first direction and a second connecting portion extending in a second direction, the first connecting portion being fixedly connected to the baffle, and the second connecting portion being arbitrarily connected to the baffle bar or the second frame.

[0018] The first right-angle piece is used to adjustably connect the stop bar to the stop bar or the second frame. This ensures the connection strength between the stop bar and the stop bar or the second frame, and also ensures that the stop bar can slide smoothly along the stop bar or the second frame without getting stuck.

[0019] In some embodiments, the two ends of the stop bar are respectively adjustablely connected to the first frame via a second right-angle member; the second right-angle member includes a third connecting portion extending in a first direction and a fourth connecting portion extending in a second direction, the third connecting portion being fixedly connected to the stop bar, and the fourth connecting portion being adjustablely connected to the first frame.

[0020] The two ends of the stop bar are adjusted to be connected to the first frame using a second right-angle piece. This ensures the connection strength between the stop bar and the first frame and also ensures that the stop bar can slide smoothly along the first frame without getting stuck.

[0021] In some embodiments, a silicone strip is provided on the upper surface of the baffle.

[0022] By setting a silicone strip of appropriate thickness on the upper surface of the baffle, the pressure of the pressure plate on the edge of the photovoltaic module can be adjusted, thus avoiding pressure damage to the edge of the photovoltaic module while ensuring the lamination effect.

[0023] In some embodiments, the protective frame further includes a plurality of flexible connectors disposed circumferentially on the frame; the protective frame is suspended below the top cover of a single-layer laminator or below the top cover or lamination unit of a multi-layer laminator via the flexible connectors; the flexible connectors include strips of cloth, connecting ropes or rubber springs.

[0024] By installing flexible connectors on the protective frame, the protective frame can be easily suspended below the top cover of a single-layer laminator, or below the top cover or lamination unit of a multi-layer laminator.

[0025] This application also provides a single-layer laminator, comprising a first base, a first top cover, a first lifting mechanism, a first high-temperature cloth, a first roller group, a first drive mechanism, a second high-temperature cloth, a second roller group, a second drive mechanism, and a protective frame as described in any one of the above, wherein:

[0026] The first top cover is located above the first base, and the drive end of the first lifting mechanism is connected to the first top cover. The first lifting mechanism is configured to drive the first top cover to move towards or away from the first base, so as to realize the opening or closing of the single-layer laminator.

[0027] The protective frame is suspended below the first top cover;

[0028] The first high-temperature cloth is sleeved on the first roller group. The drive end of the first drive mechanism is connected to the first roller group. The first drive mechanism drives the first roller group to rotate to realize the operation of the first high-temperature cloth. The first high-temperature cloth covers the first top cover and the protective frame.

[0029] The second high-temperature cloth is fitted onto the second roller group. The drive end of the second drive mechanism is connected to the second roller group. The second drive mechanism drives the second roller group to rotate, thereby realizing the operation of the second high-temperature cloth. The second high-temperature cloth covers the first base and can support at least two photovoltaic modules above the first base.

[0030] When the single-layer laminator is closed, a photovoltaic module can be fitted into each protective space. The first top cover laminates the photovoltaic module fitted into the protective space.

[0031] The single-layer laminator provided in this application has a protective frame suspended on its top cover. When the laminator is closed, the protective frame automatically falls and fits onto the photovoltaic module located on the first base, driven by the first top cover. When the lamination process is completed and the cover is opened, the protective frame automatically detaches from the photovoltaic module, driven by the first top cover. This eliminates the need for manual handling of the protective frame for loading and unloading, thereby improving the lamination production efficiency of the photovoltaic module.

[0032] This application also provides a multi-layer laminator, including a second base, a second top cover, several lamination units, a second lifting mechanism, a third high-temperature fabric, a third roller group, a third drive mechanism, a fourth high-temperature fabric, a fourth roller group, a fourth drive mechanism, and several protective frames as described in any one of the above claims, wherein:

[0033] The second top cover, several laminated units and the second base are arranged in layers from top to bottom;

[0034] A protective frame is suspended below the second top cover and each lamination unit;

[0035] The third high-temperature cloth is fitted onto the third roller group. The drive end of the third drive mechanism is connected to the third roller group. The third drive mechanism drives the third roller group to rotate, thereby enabling the operation of the third high-temperature cloth. The third high-temperature cloth covers the second top cover and the protective frame hanging below the second top cover.

[0036] The fourth high-temperature cloth is fitted onto the fourth roller group. The drive end of the fourth drive mechanism is connected to the fourth roller group. The fourth drive mechanism drives the fourth roller group to rotate, thereby realizing the operation of the fourth high-temperature cloth. The fourth high-temperature cloth covers the second base and can support at least two photovoltaic modules above the second base. The lamination unit can support at least two photovoltaic modules.

[0037] The second lifting mechanism is configured to drive the second top cover and several laminating units to rise, so that adjacent laminating units, the second top cover and the uppermost laminating unit, the lowermost laminating unit and the second base move away from each other, thereby opening the multilayer laminating machine; and to drive the second top cover and several laminating units to fall, so that adjacent laminating units, the second top cover and the uppermost laminating unit, the lowermost laminating unit and the second base move closer to each other, thereby closing the multilayer laminating machine.

[0038] When the multi-layer laminator is closed, a photovoltaic module can be fitted into each protective space in the protective frame suspended below the second top cover and each protective space in the protective frame suspended below each lamination unit. The second top cover and each lamination unit laminate the photovoltaic modules fitted into the protective spaces.

[0039] The multilayer laminator provided in this application has protective frames suspended below its second top cover and each lamination unit. When the multilayer laminator is closed, the protective frames automatically fall and fit onto the photovoltaic modules located below, driven by the second top cover or lamination unit. When the lamination process is completed and the cover is opened, the protective frames automatically detach from the photovoltaic modules, driven by the second top cover or lamination unit. This eliminates the need for manual handling of the protective frames for loading and unloading, thus improving the lamination production efficiency of the photovoltaic modules.

[0040] In some embodiments, the laminating unit includes a heating plate, a pressure frame, a pressure plate, a driving roller, a driven roller, a fifth driving mechanism, and a fifth high-temperature fabric, wherein:

[0041] The pressure frame is fixedly connected to the four edges of the heating plate;

[0042] The pressure plate is positioned below the heating plate, and its four edges are sealed and installed on the pressure frame. The pressure plate, the pressure frame, and the heating plate together form a sealed air cavity.

[0043] The protective frame is suspended on the pressure frame and located below the pressure plate;

[0044] The active roller and the driven roller are set at both ends of the heating plate. The driving end of the fifth driving mechanism is connected to the active roller. The fifth high-temperature cloth is sleeved on the active roller and the driven roller. The fifth driving mechanism is configured to drive the fifth high-temperature cloth to rotate. The fifth high-temperature cloth covers the outer periphery of the heating plate, the pressure plate and the protective frame. The fifth high-temperature cloth is configured to support the photovoltaic module above the heating plate.

[0045] By configuring the lamination units, each lamination unit can laminate the photovoltaic modules located below it, and can automatically load and unload the photovoltaic modules supported on it. Attached Figure Description

[0069] Protective space S, photovoltaic module 100. Detailed Implementation

[0070] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0071] As described in the background section, in the prior art, before entering the laminator (single-layer or multi-layer), a rectangular protective frame needs to be manually placed on each photovoltaic module. After laminating the photovoltaic modules, the protective frame is then manually removed. Placing and removing the protective frame on each photovoltaic module is time-consuming, labor-intensive, and inefficient.

[0072] To this end, this application provides a protective frame that can be suspended below the top cover of a single-layer laminator, or below the top cover or lamination unit of a multi-layer laminator, to protect the edges of the laminated photovoltaic modules during lamination.

[0073] like Figures 1 to 2 As shown, the protective border 10 provided in this application includes:

[0074] The rectangular frame 1 is composed of two first borders 11 extending along a first direction (such as the X direction) and two second borders 12 extending along a second direction (such as the Y direction), connected end to end, with the second direction perpendicular to the first direction.

[0075] N baffles 2 are arranged at intervals along a first direction. The baffles 2 extend along a second direction, and their two ends are connected to two first frame members 11. A protective space S is formed between two adjacent baffles 2, and between the second frame member 12 adjacent to the Nth baffle 2 and the Nth baffle 2. Each protective space S is used to house a photovoltaic module 100.

[0076] The specific value of N can be selected and set according to the number of photovoltaic modules 100 required to be laminated in each batch, for example... Figure 1 In the illustrated embodiment, N = 7. That is, 7 stop bars 2, and the second frame 12 adjacent to the 7th stop bar 2. Figure 1 The second frame 12 located at the right end of the frame 1, together with the frame 1, divides the inner side of the frame 1 into 7 protective spaces S, thereby protecting the 7 photovoltaic modules 100. Of course, in other embodiments, N can also be 2, 3, 4, 5, 6, 8 or other numbers, so that the frame 1 forms a corresponding number of protective spaces S.

[0077] like Figure 7 As shown, the protective frame 10 provided in this application is suspended below the top cover of a single-layer laminator. Of course, the protective frame 10 provided in this application can also be suspended below the top cover of a multi-layer laminator or below a lamination unit.

[0078] When the single-layer laminator or multi-layer laminator closes its lid, the protective frame 10 automatically falls and fits onto the photovoltaic module 100 located below it, driven by the top cover or lamination unit. When the lamination is completed and the lid is opened, the protective frame 10 automatically detaches from the photovoltaic module 100, driven by the top cover or lamination unit. This eliminates the need for manual handling of the protective frame 10 for loading and unloading, saving labor and improving the lamination production efficiency of the photovoltaic module.

[0079] Optional, such as Figure 1 As shown, the protective frame 10 in this embodiment further includes 4N baffles 3. The 4N baffles 3 extend along a first direction (e.g., the X direction), and baffles 3 are provided at the four corners of each protective space S. Specifically: of the four baffles 3 in the i-th protective space, two are located on the i-th baffle 2, and the other two are located on the (i+1)-th baffle 2. In the N-th protective space, two of the four baffles 3 are located on the N-th baffle 2, and the other two are located on the second frame 12 adjacent to the N-th baffle 2; N ≥ 2, 1 ≤ i < N.

[0080] by Figure 1 Taking the illustrated embodiment as an example, seven protective spaces S are formed within the protective frame 10, and a baffle 3 is provided at each of the four corners of each protective space S, for a total of 28 baffles. Among them, from... Figure 1 Sorting from the first side (e.g., left) to the second side (e.g., right):

[0081] Of the four baffles 3 in the first protective space, two are set on the first baffle 2 and the other two are set on the second baffle 2.

[0082] Of the four baffles 3 in the second protective space S, two are located on the second baffle 2 and the other two are located on the third baffle 2.

[0083] Of the four baffles 3 in the third protective space S, two are located on the third baffle 2 and the other two are located on the fourth baffle 2.

[0084] Of the four baffles 3 in the fourth protective space S, two are located on the fourth baffle 2 and the other two are located on the fifth baffle 2.

[0085] Of the four baffles 3 in the fifth protective space S, two are located on the fifth baffle 2 and the other two are located on the sixth baffle 2.

[0086] Of the four baffles 3 in the sixth protective space S, two are located on the sixth baffle 2 and the other two are located on the seventh baffle 2.

[0087] Of the four baffles 3 in the 7th protective space S, two are set on the 7th baffle 2, and the other two are set on the second frame 12 (i.e. the right side of the second frame 12) adjacent to the 7th baffle 2.

[0088] Each baffle 3 is perpendicularly connected to the adjacent baffle 2 or the second frame 12, so that each protective space S is a rectangular space to fit the shape of the rectangular photovoltaic module 100. The positional relationship between the protective space S and the photovoltaic module 100 when they are in conjunction is referenced. Figure 1 .

[0089] Since each protective space S has a baffle 3 at its four corners, the baffle 3 also supports the pressure plate during the lamination process. Thus, for each protective space S, the four baffles 3 can work with the baffle 2 or the second frame 12 to protect the four corners of the photovoltaic module, preventing the four corners of the photovoltaic module from being damaged by excessive pressure.

[0090] Optionally, the two ends of the stop lever 2 are respectively adjustablely connected to the two first frame 11, and the stop lever 2 can move along the first frame 11 to adjust its position in a first direction (such as the X direction). The stop bar 3 is adjustablely connected to the corresponding stop lever 2 or second frame 12, and the stop bar 3 can move along the stop lever 2 or second frame 12 to adjust its position in a second direction (such as the Y direction).

[0091] By adjusting the position of the baffle 2 in the first direction and the position of the baffle 3 in the second direction, each protective space S can be made compatible with photovoltaic modules 100 of different sizes, thereby improving the versatility of this application.

[0092] by Figure 1 Taking the protective frame 10 in the illustrated embodiment as an example, its optional adjustment process is as follows:

[0093] First, based on the width of the photovoltaic module 100 along the first direction (such as the X direction), and taking the second frame 12 adjacent to the 7th baffle 2 (i.e., the second frame 12 at the right end) as a reference, the positions of the 6th, 5th, 4th, 3rd, 2nd and 1st baffles 2 are adjusted sequentially from right to left in the first direction, so that the width of each protective space S along the first direction (such as the X direction) is adapted to the width of the photovoltaic module 100 along the first direction.

[0094] Next, based on the length of the photovoltaic module 100 along the second direction (such as the Y direction), the positions of the four baffles 3 in each protective space S are adjusted in the second direction so that the distance between the two baffles 3 located on the same baffle 2 or on the second frame 12 is adapted to the length of the photovoltaic module 100 along the second direction.

[0095] like Figures 3 to 6 As shown, optionally, the stop bar 3 is arbitrarily connected to the stop bar 2 or the second frame 12 via the first right-angle member 4. The first right-angle member 4 includes a first connecting portion 41 extending along a first direction (e.g., the X direction) and a second connecting portion 42 extending along a second direction (e.g., the Y direction). The first connecting portion 41 is fixedly connected to the stop bar 3, and the second connecting portion 42 is arbitrarily connected to the stop bar 2 or the second frame 12.

[0096] The first right-angle piece 4 is used to adjustably connect the stop bar 3 to the stop bar 2 or the second frame 12. This ensures the connection strength between the stop bar 3 and the stop bar 2 or the second frame 12, and also ensures that the stop bar 3 can slide smoothly along the stop bar 2 or the second frame 12 to avoid jamming.

[0097] like Figure 3 As shown, taking the stop bar 3 as an example, optionally, the stop bar 3, the stop rod 2, and the second frame 12 are all profiles with two strip grooves 7. The two strip grooves 7 are set on two opposite sides of the profile, such as... Figure 3 As shown, the cross-section of the strip groove is cross-shaped, corresponding to, as Figure 6 As shown, the cross-sections of the first connecting portion 41 and the second connecting portion 42 of the first right-angle piece 4 are also cross-shaped to fit the strip groove 7. Furthermore, the first connecting portion 41 and the second connecting portion 42 also have screw holes 44. The first connecting portion 41 is slidably mounted in the strip groove 7 on the stop bar 3 and fixed to the stop bar 3 by a set screw located in the screw hole 44. The second connecting portion 42 is slidably mounted in the strip groove 7 on the stop bar 2 or the second frame 12 and fixed to the stop bar 2 or the second frame 12 by a set screw located in the screw hole 44. When the position of the stop bar 3 needs to be adjusted, simply loosen the set screw on the second connecting portion 42 to push the stop bar 3 to slide along the stop bar 2 or the second frame 12. After the sliding adjustment is in place, retighten the set screw to fix the second connecting portion 42.

[0098] Optionally, both ends of the stop bar 2 are adjustablely connected to the first frame 11 via a second right-angle member. The second right-angle member includes a third connecting portion extending along a first direction and a fourth connecting portion extending along a second direction. The third connecting portion is fixedly connected to the stop bar 2, and the fourth connecting portion is adjustablely connected to the first frame 11. The second right-angle member and the first right-angle member 4 have the same structure, installation, and adjustment methods. They will not be described again here.

[0099] Similarly, the two ends of the stop bar 2 are adjusted to be connected to the first frame 11 by the second right-angle piece. This ensures the connection strength between the stop bar 2 and the first frame 11, and also ensures that the stop bar 2 can slide smoothly along the first frame 11 to avoid jamming.

[0100] like Figures 3 to 5 As shown, optionally, a silicone strip 5 is also provided on the upper surface of the baffle 3.

[0101] By setting a silicone strip 5 of appropriate thickness on the upper surface of the baffle 3, the pressure of the pressure plate on the edge of the photovoltaic module can be adjusted, so as to avoid pressure damage to the edge of the photovoltaic module while ensuring the lamination effect.

[0102] like Figure 1 and Figure 7 As shown, the protective frame 10 also includes several flexible connectors 6 arranged circumferentially on the frame 1. The protective frame 10 is suspended below the top cover of a single-layer laminator, or below the top cover or lamination unit of a multi-layer laminator, via the flexible connectors 6. The flexible connectors can be strips of cloth, connecting ropes, or rubber springs, etc. The strips of cloth, connecting ropes, or rubber springs must be made of high-temperature resistant materials to withstand the high-temperature environment of the laminator.

[0103] By providing a flexible connector 6 on the protective frame 10, the protective frame 10 can be easily suspended below the top cover of a single-layer laminator, or below the top cover or lamination unit of a multi-layer laminator.

[0104] like Figure 8 When the flexible connector 6 is a cloth strip, one optional installation method is as follows: the lower end of the cloth strip is fixedly connected to an ear plate 8, which is bolted to the protective frame 10. The upper end of the cloth strip is connected to a mounting plate 9, which has screw holes. The mounting plate 9 is screwed to the top cover of a single-layer laminator or to the top cover or lamination unit of a multi-layer laminator through the screw holes, thus completing the suspension installation of the protective frame 10.

[0105] Of course, the flexible connector 6 can also be installed in other ways, as long as it can be used to suspend the protective frame 10.

[0106] This application also provides a single-layer laminator. For example... Figure 9 As shown, the single-layer laminator 20 of this application includes a first base 21, a first top cover 22, a first lifting mechanism 29, a first high-temperature cloth 23, a first roller group 24, a first drive mechanism, a second high-temperature cloth 25, a second roller group 26, and a protective frame 10 provided in any of the above embodiments, wherein:

[0107] The first top cover 22 is located above the first base 21. The drive end of the first lifting mechanism 29 is connected to the first top cover 22. The first lifting mechanism 29 is configured to drive the first top cover 22 to move up or down toward or away from the first base 21, so as to realize the opening or closing of the single-layer laminator 20.

[0108] The protective frame 10 is suspended below the first top cover 22.

[0109] The first high-temperature cloth 23 is sleeved on the first roller group 24. The driving end of the first driving mechanism is connected to the first roller group 24. The first driving mechanism drives the first roller group 24 to rotate to realize the operation of the first high-temperature cloth 23. The first high-temperature cloth 23 covers the first top cover 22 and the protective frame 10.

[0110] The second high-temperature cloth 25 is sleeved on the second roller group 26. The driving end of the second driving mechanism is connected to the second roller group 26. The second driving mechanism drives the second roller group 26 to rotate to realize the operation of the second high-temperature cloth 25. The second high-temperature cloth 25 covers the first base 21. The second high-temperature cloth 25 can support at least two photovoltaic modules 100 above the first base 21.

[0111] When the single-layer laminator 20 is closed, a photovoltaic module 100 can be fitted into each protective space S of the protective frame 10, and the first top cover 22 performs lamination on the photovoltaic module 100 fitted into the protective space S.

[0112] The first base 21 of the single-layer laminator 20 of this application has a heating function. For example, the first base 21 has a heating rod or heating oil inside, which can heat the photovoltaic module 100 during lamination.

[0113] like Figure 9 As shown, the first drive mechanism and the second drive mechanism share a single motor 27. The first roller group and the second roller group are linked through a gear pair 28. One motor 27 drives the first roller group and the second roller group to rotate simultaneously, thereby driving the first high-temperature cloth 23 and the second high-temperature cloth 25 to rotate simultaneously. Of course, the first drive mechanism and the second drive mechanism can also use independent motors, with two motors driving the first roller group and the second roller group to rotate respectively.

[0114] The single-layer laminator provided in this application has a protective frame 10 suspended on its top cover. When the laminator is closed, the protective frame 10 automatically falls and fits onto the photovoltaic module 100 located on the first base 21 under the action of the first top cover. When the lamination is completed and the cover is opened, the protective frame 10 automatically detaches from the photovoltaic module 100 under the action of the first top cover 22. This eliminates the need for manual handling of the protective frame 10 for loading and unloading, thereby improving the lamination production efficiency of the photovoltaic module 100.

[0115] The first high-temperature cloth 23 covering the first top cover 22 and the protective frame 10, and the second high-temperature cloth 25 covering the first base 21, can provide anti-stick protection for the first top cover 22, the protective frame 10, and the first base 21, preventing the photovoltaic module from sticking to the first top cover 22, the protective frame 10, and the first base 21, thus affecting subsequent opening operations. In addition, the second high-temperature cloth 25 also has a conveying function to realize automatic loading and unloading of the photovoltaic module 100.

[0116] This application also provides a multi-layer laminator, such as Figure 10 As shown, the multilayer laminator 30 of this application includes a second base 31, a second top cover 32, a plurality of laminating units 33, a second lifting mechanism, a third high-temperature cloth 34, a third roller group 35, a third drive mechanism, a fourth high-temperature cloth 36, a fourth roller group 37, a fourth drive mechanism, and a plurality of protective frames 10 as provided in any of the above embodiments, wherein:

[0117] The second top cover 32, several laminated units 33 and the second base 31 are arranged in layers from top to bottom.

[0118] A protective frame 10 is suspended below the second top cover 32 and each lamination unit 33.

[0119] The third high-temperature cloth 34 is fitted onto the third roller group 35. The drive end of the third drive mechanism is connected to the third roller group 35. The third drive mechanism drives the third roller group 35 to rotate, thereby realizing the operation of the third high-temperature cloth 34. The third high-temperature cloth 34 covers the second top cover 32 and the protective frame 10 suspended below the second top cover 32.

[0120] A fourth high-temperature fabric 36 is fitted onto a fourth roller group 37. The drive end of a fourth drive mechanism is connected to the fourth roller group 37. The fourth drive mechanism drives the fourth roller group 37 to rotate, thereby operating the fourth high-temperature fabric 36. The fourth high-temperature fabric 36 covers the second base 31 and can support at least two photovoltaic modules on top of the second base 31. The lamination unit 33 can support at least two photovoltaic modules. The fourth drive mechanism can be a motor, and the second base 31 is plate-shaped with embedded heating rods to provide heating functionality. During the lamination process, the second base 31 can heat the photovoltaic modules on it.

[0121] The second lifting mechanism is configured to drive the second top cover 32 and several laminating units 33 to rise, so that the adjacent laminating units 33, the second top cover 32 and the uppermost laminating unit 33, and the lowermost laminating unit 33 and the second base 31 are moved away from each other, so as to realize the opening of the multilayer laminator 30.

[0122] The second lifting mechanism is also configured to drive the second top cover 32 and several laminating units 33 to descend, so that the adjacent laminating units 33, the second top cover 32 and the uppermost laminating unit 33, and the lowermost laminating unit 33 and the second base 31 move closer to each other, so as to close the multi-layer laminator 30.

[0123] When the multi-layer laminator 30 is closed, a photovoltaic module can be fitted into each protective space S in the protective frame 10 suspended below the second top cover 32 and each protective space S in the protective frame 10 suspended below each lamination unit 33. The second top cover 32 and each lamination unit 33 perform lamination on the photovoltaic modules fitted into the protective spaces S.

[0124] The third and fourth drive mechanisms can also be motors. The second lifting mechanism includes hydraulic cylinders, etc., and can adopt the lifting mechanism of an existing multi-layer laminator, which will not be described in detail.

[0125] The multilayer laminator provided in this application has protective frames 10 suspended below the second top cover 32 and each lamination unit 33. Thus, when the multilayer laminator 30 is closed, the protective frames 10 automatically fall and fit onto the photovoltaic module located below it, driven by the second top cover 32 or the lamination unit 33. When the lamination is completed and the cover is opened, the protective frames 10 automatically detach from the photovoltaic module, driven by the second top cover 32 or the lamination unit 33. This eliminates the need for manual handling of the protective frames 10 for loading and unloading, improving the lamination production efficiency of the photovoltaic module.

[0126] The third high-temperature cloth 34 covering the second top cover and the protective frame 10, and the fourth high-temperature cloth 36 covering the second base 31 can achieve anti-stick protection for the second top cover 32, the protective frame 10 and the second base 31, and prevent the photovoltaic module from sticking to the second top cover 32, the protective frame 10 and the second base 31, which would affect the subsequent opening operation.

[0127] In addition, since the fourth high-temperature cloth 36 is installed on the fourth roller group 37, the fourth high-temperature cloth 36 has a conveying function to realize the automatic loading and unloading of photovoltaic modules at the corresponding positions.

[0128] Optionally, the laminating unit 33 includes a heating plate 331, a pressure frame 332, a pressure plate 333, a driving roller 334, a driven roller 335, a fifth driving mechanism, and a fifth high-temperature fabric 336, wherein:

[0129] The pressure frame 332 is fixedly connected to the four edges of the heating plate 331.

[0130] The pressure plate 333 is located below the heating plate 331. The four edges of the pressure plate 333 are sealed and installed on the pressure frame 332. The pressure plate 333, the pressure frame 332 and the heating plate 331 form a sealed air cavity.

[0131] The protective frame 10 is suspended on the pressure frame 332 and located below the pressure plate 333;

[0132] The active roller 334 and the driven roller 335 are located at both ends of the heating plate 332. The driving end of the fifth driving mechanism is connected to the active roller 334. The fifth high-temperature cloth 336 is sleeved on the active roller 334 and the driven roller 335. The fifth driving mechanism is configured to drive the fifth high-temperature cloth 336 to rotate. The fifth high-temperature cloth 336 covers the outer periphery of the heating plate 331, the pressure plate 333 and the protective frame 10. The fifth high-temperature cloth 336 is configured to support the photovoltaic module above the heating plate 331.

[0133] The fifth drive mechanism can be an electric motor, which drives the fifth high-temperature cloth 336 to rotate through the active roller 334 and the driven roller 335.

[0134] By configuring the lamination units 33, each lamination unit 33 can laminate the photovoltaic module located below it. Furthermore, the fifth high-temperature cloth 336, which is fitted onto the driving roller 334 and the driven roller 335 and covers the heating plate 331, pressure plate 333, and protective frame 10, provides anti-stick protection for the heating plate 331, pressure plate 333, and protective frame 10, preventing the photovoltaic module from sticking to these components and affecting subsequent opening operations. Moreover, driven by the driving roller 334 and the driven roller 335, the fifth high-temperature cloth 336 on each lamination unit 33 can automatically load and unload the photovoltaic module located on it.
