DETAILED DESCRIPTION

[0047] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The existing laminator is a single-layer structure, and the upper chamber of the laminator and the laminating bearing unit are fixedly arranged, which makes maintenance extremely inconvenient.

[0049] To this end, the present application provides a lamination unit. Figures 1 to 4 As shown, the laminating unit 15 of the embodiment of the present application includes a pressing plate component 151, an active roller 154, a driven roller 155 and a laminating belt 152, wherein:

[0050] A first connecting piece 1540 is provided at the first end of the pressing plate component 151 , and a second connecting piece 1550 is provided at the second end of the pressing plate component 151 . The pressing plate component 151 is detachably installed in the laminator frame through the first connecting piece 1540 and the second connecting piece 1550 .

[0051] The active roller 154 is disposed at the first end of the pressure plate component 151, the driven roller 155 is disposed at the second end of the pressure plate component 151, and the laminating belt 152 is wound around the active roller 154 and the driven roller 155 and covers the pressure plate component 151. The active roller 154 is used to drive the laminating belt 152 to operate so as to convey the photovoltaic components carried on the laminating belt 152.

[0052] The laminating unit 15 provided by the present application can be detachably installed in the frame of the laminating machine through the first connecting member 1540 and the second connecting member 1550 at both ends. When it is necessary to perform maintenance on a laminating unit 15, it is only necessary to remove the laminating unit 15 for offline maintenance. The maintenance process does not affect the normal use of the laminating machine, thereby improving the production efficiency of the laminating machine. In addition, by setting a laminating belt, the transmission of the photovoltaic components carried on the laminating belt 152 is achieved.

[0053] Optionally, the laminating unit 15 in the embodiment of the present application further includes a silicone plate 153 disposed between the lower side of the pressing plate component 151 and the laminating belt 152 on the lower side of the pressing plate component. When the laminating machine is working, two adjacent laminating units 15 press the photovoltaic module therebetween from the upper and lower sides, and the silicone plate 153 is used to press downward the laminating belt section located below the pressing plate component 151, thereby increasing the laminating strength of the laminating belt section below the pressing plate component 151 on the photovoltaic module and improving the laminating effect.

[0054] Optionally, an air cavity that can be evacuated and ventilated is provided between the silicone plate 153 and the pressure plate component 151. When two adjacent laminating units 15 press the photovoltaic module therebetween from the upper and lower sides, the air cavity in the laminating unit 15 is evacuated by the negative pressure device, so that negative pressure can be generated between the adjacent laminating units 15, and then ventilation is performed between the silicone plate and the pressure plate component, so that the silicone plate can swell, driving the laminating belt to approach the photovoltaic module, and completing the lamination of the photovoltaic module. In this way, the laminating belts 152 of the adjacent laminating units 15 can continuously press the photovoltaic module therebetween, further improving the laminating effect.

[0055] like Figure 2 and Figure 3 As shown, optionally, the laminating unit 15 in the embodiment of the present application further includes a limiting assembly 158 disposed on the side of the pressure plate component 151, and the limiting assembly 158 extends downward or upward from the pressure plate component 151 to adjust the spacing between the laminating unit 15 and the adjacent laminating unit 15, so that the adjacent laminating units 15 can achieve lamination of photovoltaic modules of different thicknesses. Of course, for the laminating unit 15 at the bottom, the limiting assembly 158 thereon is used to adjust the spacing between the laminating unit 15 and the bottom pressure member below it.

[0056] Optionally, the limiting assembly 158 includes a mounting portion 1581 and an adjusting portion 1582, wherein: the mounting portion 1581 is fixed to the side of the pressure plate component 151, and the mounting portion 1581 is provided with an adjusting portion 1582 which can vertically move along the mounting portion 1581, and the adjusting portion 1582 is used to adjust the distance between the laminating unit 15 and the laminating unit 15 below or above.

[0057] The mounting portion 1581 may be, for example, a mounting block, on which a screw hole extending in the vertical direction is provided, and the adjusting portion 1582 may be, for example, a bolt screwed into the screw hole, with the end of the bolt extending downward or upward from the pressing plate component 151. By screwing the bolt, the spacing between the laminating unit 15 and the adjacent laminating unit 15 can be adjusted.

[0058] Continue to refer Figure 1As shown, optionally, the first active roller mounting bracket 159 and the second active roller mounting bracket 1510 are respectively provided on both sides of the first end of the pressure plate component 151, and the two ends of the active roller 154 are respectively rotatably connected to the first active roller mounting bracket 159 and the second active roller mounting bracket 1510. The first driven roller mounting bracket 1520 and the second driven roller mounting bracket 1530 are respectively provided on both sides of the second end of the pressure plate component 151, and the two ends of the driven roller 155 are respectively rotatably connected to the first driven roller mounting bracket 1520 and the second driven roller mounting bracket 1530. The laminating unit 15 also includes a driver 156, which is arranged on the first active roller mounting bracket 159 and is in transmission connection with the first active roller 154. The driver 156 is used to drive the first active roller 154 to rotate, thereby driving the laminating belt 152 to operate. When the laminating belt 152 is in operation, the photovoltaic components carried on the upper belt body of the laminating belt 152 can be transported.

[0059] like Figure 2 and Figure 3 As shown, optionally, a first connecting member 1540 is installed on each of the first active roller mounting bracket 159 and the second active roller mounting bracket 1510. A second connecting member 1550 is installed on each of the first driven roller mounting bracket 1520 and the second driven roller mounting bracket 1530.

[0060] Such an arrangement allows the four corners of the pressure plate component 151 to be connected to the frame of the laminator via a first connecting member 1540 or a second connecting member 1550, thereby ensuring the connection stability of the pressure plate component 151 and enabling the pressure plate component 151 to remain horizontal, thereby improving the lamination effect of the photovoltaic module.

[0061] Optionally, the first connecting member 1540 and the second connecting member 1550 are detachably connected to the pressing plate component 151 by bolts. The first connecting member 1540 and the second connecting member 1550 are at least one of a hook, a block or a bolt connection structure.

[0062] The hook can be, for example, a ring-shaped structure or an arc-shaped structure with a concave inner side, and correspondingly, the frame of the laminator is provided with a mounting piece that matches the hook. The clamping block can be, for example, a strip-shaped protruding block, and correspondingly, the frame of the laminator is provided with a strip-shaped groove, and the clamping block can be clamped into the strip-shaped groove. Of course, it can also be the other way around, with a strip-shaped groove on the clamping block and a strip-shaped protruding block on the frame of the laminator. The bolt connection structure can be, for example, a nut, and in this case, the frame of the laminator is provided with a matching bolt. Of course, the bolt connection structure can also be a bolt, and in this case, the frame of the laminator is provided with a matching nut.

[0063] In one implementation, the hook is an annular structure, the first flexible strip and the second flexible strip are both chains, the hook is coaxially connected to a connecting shaft in the chain, and when the laminating unit needs to be disassembled, the hook can be directly removed from the pressure plate component.

[0064] Optionally, the press plate component 151 includes a hot press plate, and a heating element is arranged on the hot press plate. The heating element may be, for example, a heating wire, an electromagnetic heating element, etc. By setting the press plate component 151 as a hot press plate, when two adjacent laminating units 15 laminate the photovoltaic modules therebetween, the photovoltaic modules can be heated at the same time, thereby ensuring that the EVA in the photovoltaic module is melted by heat and the cell sheet, the cover glass and the back plate are bonded together.

[0065] In one implementation, the pressure plate component 151 includes a hot pressing plate and a pressure frame installed under the hot pressing plate, the silicone plate is arranged in the pressure frame, and a sealed cavity is formed between the silicone plate, the pressure frame and the hot pressing plate. A heating element is arranged under the hot pressing plate to heat the hot pressing plate, and the heating element can be a heating rod, hot pressing oil or an induction heating coil. Alternatively, a mounting hole is arranged on the hot pressing plate, and the heating element is arranged inside the hot pressing plate.

[0066] In one implementation, the pressure plate component 151 may also be a frame-shaped structure with a flat top and a bracket at the bottom. The silicone plate is disposed in the bracket.

[0067] like Figures 5 to 7 As shown, the embodiment of the present application further provides a laminating machine 10, which includes a frame 11, a lifting drive device 12, at least two first flexible strips 13, at least two second flexible strips 14 and n laminating units 15 provided by any of the above embodiments, wherein:

[0068] The lifting drive device 12 is arranged on the frame 11 .

[0069] The upper end of the first flexible strip 13 and the upper end of the second flexible strip 14 are both connected to the driving end of the lifting drive device 12. Alternatively, the lower end of the first flexible strip 13 and the lower end of the second flexible strip 14 are both connected to the driving end of the lifting drive device 12.

[0070] The first flexible strip 13 and the second flexible strip 14 may be, for example, ropes with elastic expansion and contraction properties. The first flexible strip 13 and the second flexible strip 14 may also be chains that are stretched straight after being lifted and are gradually retracted onto the frame 11 after being lowered.

[0071] N lamination units 15 are arranged at intervals in the vertical direction, and the first end of each lamination unit 15 is detachably connected to each first flexible strip 13 via a first connecting member, and the second end of each lamination unit 15 is detachably connected to each second flexible strip 14 via a second connecting member, and lamination of a photovoltaic module can be implemented between two adjacent lamination units 15.

[0072] The lifting drive device 12 is used to vertically drive the first flexible strip 13 and the second flexible strip 14 to deform, so as to drive the laminating units to move closer to or away from each other.

[0073] When the lamination unit 15 is in a lamination state, the lamination tape segment located above the pressure plate component 151 is used to carry the photovoltaic module, and the lamination tape segment located below the pressure plate component presses down another photovoltaic module located below the lamination unit.

[0074] The working process of the laminator 10 in the embodiment of the present application is as follows:

[0075] First, the first flexible strip 13 and the second flexible strip 14 are driven by the lifting drive device 12 so that the adjacent laminating units 15 are in a distanced state.

[0076] Then, a photovoltaic module to be laminated is placed on each lamination unit 15 .

[0077] Next, the first flexible strip 13 and the second flexible strip 14 are driven in reverse direction by the lifting drive device 12 so that the adjacent lamination units 15 are brought closer together until the photovoltaic components therebetween are compressed.

[0078] It can be seen that the laminator 10 provided in the embodiment of the present application can implement lamination of multiple photovoltaic modules simultaneously, thereby improving production efficiency.

[0079] In particular, since the laminating unit 15 is detachably connected to the first flexible strip 13 and the second flexible strip 14, when it is necessary to perform maintenance on one of the laminating units 15, it is only necessary to remove the laminating unit 15 for offline maintenance, and the maintenance process does not affect the normal use of the laminating machine. Of course, before lamination, the number of laminating units can also be increased or decreased according to the number of photovoltaic modules to be processed, thereby further improving the flexibility of the present application.

[0080] The first flexible strip may be a steel wire rope or a chain.

[0081] like Figure 4 As shown, optionally, the lifting drive device 12 includes a lifting hanger 122, and the lifting hanger 122 is connected to the frame 11 via a slide rail. Figure 4In the embodiment, the first flexible strip 13 and the second flexible strip 14 are chains. The upper end of the first flexible strip 13 is connected to the first end of the lifting hanger 122, and the upper end of the second flexible strip 14 is connected to the second end of the lifting hanger 122. When the lifting hanger 122 rises, the first flexible strip 13 and the second flexible strip 14 are lifted upward by the lifting hanger 122, thereby driving the adjacent lamination units 15 to separate. When the lifting hanger 122 descends, the first flexible strip 13 and the second flexible strip 14 fall from the bottom to the top of the frame 11, thereby driving the adjacent lamination units 15 to approach, so as to implement the lamination of the corresponding photovoltaic modules.

[0082] Of course, when one of the lamination units 15 is removed for maintenance, the two lamination units 15 on the upper and lower sides of the removed lamination unit 15 can still approach each other as the first flexible strip 13 and the second flexible strip 14 are lowered, and finally laminate the photovoltaic components therebetween.

[0083] In other embodiments, the first flexible strip 13 and the second flexible strip 14 are ropes with telescopic properties. In this case, the lower ends of the first flexible strip 13 and the second flexible strip 14 can be connected to the lifting hanger 122, or the upper ends of the first flexible strip 13 and the second flexible strip 14 can be connected to the lifting hanger 122. Take the example of connecting the lower ends of the first flexible strip 13 and the second flexible strip 14 to the lifting hanger. At this time, the upper ends of the first flexible strip 13 and the second flexible strip 14 are connected to the frame 11. When the lifting hanger 122 descends, the first flexible strip 13 and the second flexible strip 14 are stretched downward by the lifting hanger 122, thereby driving the adjacent lamination units 15 to separate, and when the lifting hanger 122 rises, the first flexible strip 13 and the second flexible strip 14 contract, thereby bringing the adjacent lamination units 15 closer to implement lamination of photovoltaic modules.

[0084] Similarly, when one of the lamination units 15 is removed for maintenance, the two lamination units 15 on the upper and lower sides of the removed lamination unit 15 can still move closer to each other as the first flexible strip 13 and the second flexible strip 14 shrink, and finally laminate the photovoltaic components therebetween.

[0085] Optionally, the lifting drive device 12 further includes a lifting drive 121 disposed on the frame 11 and transmission-connected to the lifting hanger 122, and the lifting drive 121 is used to drive the lifting hanger 122 to slide up and down. The lifting drive 121 can be, for example, a hydraulic cylinder. In order to improve the sliding stability of the lifting hanger 122 and ensure the horizontality of the lifting hanger 122 during the sliding process, four lifting drives 121 are provided, and the driving end of each lifting drive 121 is connected to a corner of the lifting hanger 122, and the four lifting drives 121 synchronously drive the lifting hanger 122 to rise and fall and slide.

[0086] Optionally, the laminator 10 further comprises a top pressure-bearing member and a bottom pressure-bearing member arranged on the frame 11, wherein the top pressure-bearing member is used to cooperate with the top laminating unit 15 to implement lamination of the photovoltaic modules carried on the top laminating unit 15. The bottom pressure-bearing member is used to cooperate with the top laminating unit 15 to implement lamination of the photovoltaic modules carried on the bottom pressure-bearing member.
