Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, specifically a lamination device. Background Technology

[0002] Lamination is a crucial step in the photovoltaic (PV) module manufacturing process, accomplished by a laminating machine. The laminating machine contains a lamination chamber and a pressure plate within it. The pressure plate divides the lamination chamber into a sealed upper chamber and a downward-facing lower chamber. The laminating machine also includes a heating plate located below the lower chamber. During lamination, the PV module is first placed onto the heating plate inside the laminating machine. The machine is then closed, sealing the lower chamber with the PV module inside. The heating plate heats the PV module, melting the EVA adhesive within. Simultaneously, a vacuum is created in both the upper and lower chambers, removing air bubbles from the PV module in the lower chamber. Next, the upper chamber is inflated, causing the pressure plate to deform downwards and compress the PV module. Ultimately, the molten EVA adhesive fills the gaps between the solar cells, glass, and backsheet, ensuring a strong bond between them and forming a stable PV module structure.

[0003] Existing laminators typically use oil heating or electric heating to heat photovoltaic modules. Due to limitations in the laminator's own insulation performance, this results in significant heat loss and excessive energy consumption during lamination. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a lamination device, the detailed technical solution of which is as follows:

[0005] A lamination apparatus includes an insulation chamber and a lamination main unit disposed within the insulation chamber, wherein:

[0006] The insulation chamber has a feed inlet at its first end along the length of the laminating host, which is close to the feed end of the laminating host, and a discharge outlet at its second end along the length of the laminating host, which is close to the discharge end of the laminating host.

[0007] Bottom insulation layers are provided on both sides of the laminating unit along its width direction. The bottom insulation layers extend outward and abut against the inner wall of the insulation chamber.

[0008] An insulation cavity is formed between the bottom insulation layer and the top wall of the insulation chamber.

[0009] The lamination equipment provided in this application has a lamination unit housed inside an insulated chamber. In particular, bottom insulation layers are provided on both sides of the lamination unit, and an insulation cavity is formed between the bottom insulation layers and the top wall of the insulated chamber. This ensures that the lamination cavity of the lamination unit is located within the insulation cavity, thereby reducing heat loss and ultimately reducing lamination energy consumption.

[0010] In some embodiments, the insulation chamber includes a top insulation board, a first end insulation board, a second end insulation board, a first side insulation board, and a second side insulation board, wherein: the top insulation board is located above the laminating host; the first end insulation board and the second end insulation board are located at the first end and the second end of the laminating host along its length, the feed inlet is located on the first end insulation board, and the discharge outlet is located on the second end insulation board; the first side insulation board and the second side insulation board are located on both sides of the laminating host along its width, and the bottom insulation layers on both sides of the laminating host abut against the inner walls of the first side insulation board and the second side insulation board, respectively.

[0011] The insulation chamber is designed as a cuboid structure assembled from a top insulation board, a first end insulation board, a second end insulation board, a first side insulation board, and a second side insulation board, which facilitates the assembly and disassembly of the insulation chamber.

[0012] In some embodiments, the first end insulation board, the second end insulation board, the first side insulation board, and the second side insulation board all include a board body and an insulation layer attached to the inner wall of the board body.

[0013] The structure of the panel with an insulation layer ensures that the first end insulation panel, the second end insulation panel, the first side insulation panel, and the second side insulation panel have insulation performance while also having sufficient support strength to provide stable support for the top insulation panel.

[0014] In some embodiments, the insulation layer is rubber and plastic insulation cotton, the adhesive side of which is covered with adhesive, and the adhesive side of the rubber and plastic insulation cotton is adhered to the board body by adhesive.

[0015] Using rubber and plastic insulation cotton adhered to the board as the insulation layer allows for easy replacement of the insulation layer. Furthermore, the closed-cell structure of the rubber and plastic insulation cotton has extremely low water absorption and moisture permeability, ensuring insulation performance while blocking moisture and providing corrosion protection for the board.

[0016] In some embodiments, the laminating machine is provided with a laminating chamber, and a pressure plate is provided in the laminating chamber. The pressure plate divides the laminating chamber into a sealed upper chamber and a lower chamber with an opening facing downwards. The laminating machine also includes a heating plate disposed below the lower chamber.

[0017] The laminating unit also includes an upper venting pipe, a lower venting pipe, and a venting device, wherein:

[0018] The upper vent pipe is connected to the upper chamber, and the lower vent pipe is connected to the air passage inside the heating plate;

[0019] The ventilation device includes a first air block, a first air inlet pipe, a second air inlet pipe, a first air inlet pipe, a second air inlet pipe, and an air extraction assembly, wherein:

[0020] The first air block is located on the lower side of the laminating unit. The first air block contains a first air chamber and a second air chamber. A first air inlet pipe connects the first air chamber and the upper air inlet pipe. A second air inlet pipe connects the second air chamber and the lower air inlet pipe. The lower end of the first air inlet pipe is connected to the first air block and communicates with the first air chamber. The upper end of the first air inlet pipe extends upward into the insulation chamber. The first air inlet pipe is configured to connect or disconnect the first air chamber from the insulation chamber. The lower end of the second air inlet pipe is connected to the first air block and communicates with the second air chamber. The upper end of the second air inlet pipe extends upward into the insulation chamber. The second air inlet pipe is configured to connect or disconnect the second air chamber from the insulation chamber.

[0021] The air extraction assembly is configured to extract air from the first air chamber and / or the second air chamber.

[0022] By configuring the ventilation system, it is possible to flexibly control the extraction and ventilation of the upper and lower chambers, thereby ensuring the smooth implementation of the lamination process. In particular, since the upper ends of the first and second air inlet pipes both extend upwards into the insulation cavity, they can fill the upper and lower chambers with insulating air from the insulation cavity, preventing cold air from the outside from entering and affecting the insulation effect.

[0023] In some embodiments, a first on / off valve is provided on the first air inlet pipe. When the first on / off valve is turned on, it connects the first air chamber and the insulation chamber. When the first on / off valve is turned off, it isolates the first air chamber and the insulation chamber. A second on / off valve is provided on the second air inlet pipe. When the second on / off valve is turned on, it connects the second air chamber and the insulation chamber. When the second on / off valve is turned off, it isolates the second air chamber and the insulation chamber.

[0024] By providing a first on / off valve on the first air intake pipe, the first air intake pipe can connect or disconnect the first air chamber from the insulation chamber. Similarly, by providing a second on / off valve on the second air intake pipe, the second air intake pipe can connect or disconnect the second air chamber from the insulation chamber.

[0025] In some embodiments, a muffler is provided at the upper opening of both the first air intake pipe and the second air intake pipe.

[0026] It achieves noise reduction by silencing the air intake of the first and second air intake pipes.

[0027] In some embodiments, the air extraction assembly includes a vacuum pump, a second air block, a third air inlet pipe, a first control valve, and a second control valve, wherein: a third air chamber is provided inside the second air block, and the third air chamber is connected to the first air chamber and the second air chamber respectively via the first control valve and the second control valve; the first control valve is used to connect or disconnect the third air chamber from the first air chamber, and the second control valve is used to connect or disconnect the third air chamber from the second air chamber; the first end of the third air inlet pipe is connected to the second air block and communicates with the third air chamber, and the second end of the third air inlet pipe is connected to the vacuum pump.

[0028] By configuring the vacuum pump assembly, it is possible to simultaneously evacuate both the upper and lower chambers, or to evacuate only the lower chamber.

[0029] In some embodiments, the laminating host includes an upper box, a base, a lifting drive mechanism, a first high-temperature cloth, a first roller group, a first drive mechanism, a second high-temperature cloth, a second roller group, and a second drive mechanism, wherein: the upper box is disposed above the base, the laminating chamber and the pressure plate are disposed on the upper box, the heating plate is disposed on the base, the lifting drive mechanism is connected to the upper box in a transmission manner, and the lifting drive mechanism is used to drive the upper box to move up or down toward or away from the base, so as to realize the opening or closing of the laminating host;

[0030] 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 upper box and the pressure plate.

[0031] 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 base and the pressure plate. The second high-temperature cloth can support at least two photovoltaic modules above the heating plate.

[0032] When the laminating unit is closed, the pressure plate laminates the photovoltaic modules that have entered the lower chamber of the lamination chamber.

[0033] A simple laminating machine is provided, in which a first high-temperature cloth covering the upper housing and pressure plate, and a second high-temperature cloth covering the base and pressure plate, can provide anti-stick protection for the pressure plate and heating plate, preventing the photovoltaic modules from sticking to the pressure plate and heating plate, thus avoiding interference with subsequent opening and unloading. Furthermore, since the first and second high-temperature cloths are respectively mounted on the first and second roller groups, both the first and second high-temperature cloths have conveying functions, enabling automatic loading and unloading of the photovoltaic modules.

[0034] In some embodiments, the laminating host further includes heat insulation curtains disposed on both sides of the laminating host along the width direction, the upper end of the heat insulation curtains being fixed to the upper housing, and the lower end of the heat insulation curtains hanging down to the side of the heating plate or the base, or the lower end of the heat insulation curtains being connected to the heating plate or the base.

[0035] Insulation curtains can further improve the insulation effect on the lamination cavity, thereby further reducing lamination energy consumption. Attached Figure Description

[0053] 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.

[0054] As described in the background section, existing laminating machines typically use oil heating or electric heating to heat photovoltaic modules. Due to the insulation performance of the laminating machine itself, a large amount of heat is lost, resulting in excessive energy consumption during lamination.

[0055] In view of this, this application provides a lamination apparatus. For example... Figures 1 to 3 As shown, the lamination equipment provided in this application includes an insulation chamber 1 and a lamination main unit 2 installed inside the insulation chamber 1, wherein:

[0056] The first end of the insulation chamber 1 along the length direction (e.g., the X direction) of the laminating host 2 is provided with a feed port 11 that is close to the feed end of the laminating host 2, and the second end of the insulation chamber 1 along the length direction of the laminating host 2 is provided with a discharge port 12 that is close to the discharge end of the laminating host 2.

[0057] Bottom insulation layer 3 is provided on both sides of the laminating host 2 along the width direction (such as the Y direction), and the bottom insulation layer 3 extends outward and abuts against the inner wall of the insulation chamber 1.

[0058] An insulation cavity is formed between the bottom insulation layer 3 and the top wall of the insulation chamber 1.

[0059] In operation, the inlet 11 connects to the outlet of the inlet conveyor line, and the outlet 12 connects to the inlet of the outlet conveyor line. The inlet conveyor line transports the photovoltaic modules to be laminated to the laminating machine 2 via the inlet 11. The outlet conveyor line receives the laminated photovoltaic modules output from the laminating machine 2 via the outlet 12 and outputs the photovoltaic modules to the next processing station.

[0060] The lamination equipment provided in this application has a lamination host 2 housed within an insulation chamber 1. Specifically, bottom insulation layers 3 are provided on both sides of the lamination host 2, forming an insulation cavity between the bottom insulation layer 3 and the top wall of the insulation chamber 1. This ensures that the lamination cavity of the lamination host 2 is located within the insulation cavity, thereby reducing heat loss and ultimately reducing lamination energy consumption. The lamination host 2 in this application can be an existing single-layer or multi-layer structure. A single-layer lamination host 2 is used to laminate a single-layer photovoltaic module, while a multi-layer lamination host 2 is used to laminate multiple layers of photovoltaic modules.

[0061] like Figures 1 to 2 As shown, optionally, the insulation chamber 1 includes a top insulation board 13, a first end insulation board 14, a second end insulation board 15, a first side insulation board 16, and a second side insulation board 17, wherein: the top insulation board 13 is located above the laminating host 2; the first end insulation board 14 and the second end insulation board 15 are located at the first end and the second end in the length direction of the laminating host 2, the feed inlet 11 is provided on the first end insulation board 14, and the discharge outlet 12 is provided on the second end insulation board 15; the first side insulation board 16 and the second side insulation board 17 are located on both sides in the width direction of the laminating host 2, and the bottom insulation layers 3 on both sides of the laminating host 2 abut against the inner walls of the first side insulation board 16 and the second side insulation board 17, respectively.

[0062] The insulation chamber 1 is configured as a cuboid structure consisting of a top insulation board 13, a first end insulation board 14, a second end insulation board 15, a first side insulation board 16, and a second side insulation board 17, which facilitates the assembly and disassembly of the insulation chamber 1. In addition, it also allows the bottom insulation layers 3 on both sides of the laminating host 2 to easily abut against the inner walls of both sides of the insulation chamber 1, thereby improving the insulation performance of the insulation cavity.

[0063] Optionally, the first end insulation board 14, the second end insulation board 15, the first side insulation board 16 and the second side insulation board 17 all include a board body and an insulation layer attached to the inner wall of the board body.

[0064] The structure of the panels covered with insulation layers ensures that the first end insulation panel 14, the second end insulation panel 15, the first side insulation panel 16, and the second side insulation panel 17 possess both insulation performance and sufficient support strength to stably support the top insulation panel 13. The panels can be made of metal, for example. Furthermore, the first end insulation panel 14, the second end insulation panel 15, the first side insulation panel 16, and the second side insulation panel 17 also provide safety protection.

[0065] Optionally, the insulation layer is made of rubber and plastic insulation cotton, and the adhesive side of the rubber and plastic insulation cotton is attached to the board body by adhesive.

[0066] Using rubber and plastic insulation cotton adhered to the board as the insulation layer allows for convenient installation or replacement. Furthermore, the closed-cell structure of the rubber and plastic insulation cotton has extremely low water absorption and moisture permeability, ensuring insulation performance while blocking moisture, thus providing corrosion protection for the board and extending its service life.

[0067] The top insulation board 13 can be made of polyurethane insulation board, extruded polystyrene insulation board, etc.

[0068] The bottom insulation layer 3 can be, for example, a composite insulation layer with the following structure: using rubber and plastic insulation cotton as the core material, and the outer layer is fully covered and encapsulated with flame-retardant blade-coated cloth. Alternatively, it can be a composite insulation layer with the following structure: using single-sided or double-sided aluminum foil rubber and plastic insulation material as the core material, and the outer layer is fully covered and encapsulated with flame-retardant blade-coated cloth.

[0069] The laminating unit 2 in this application can be a single-layer laminator with various existing structures. As described in the background section, the laminating unit 2 has a lamination chamber, and a pressure plate is provided in the lamination chamber. The pressure plate divides the lamination chamber into a sealed upper chamber and a lower chamber with an opening facing downwards. The laminating unit 2 also includes a heating plate disposed below the lower chamber.

[0070] During the lamination process, the photovoltaic (PV) modules are first fed onto a heating plate inside the laminator 2. The laminator 2 is then closed, sealing the lower chamber with the heating plate. The PV modules are located within the lower chamber, and the heating plate heats them, melting the EVA adhesive inside. Simultaneously, a vacuum is created in both the upper and lower chambers, removing air bubbles from the PV modules in the lower chamber. Next, air is pumped into the upper chamber, causing the pressure plate to deform downwards and compress the PV modules. Ultimately, the molten EVA adhesive fills the gaps between the solar cells, glass, and backsheet, ensuring a strong bond between the cells, glass, and backsheet, forming a stable PV module structure.

[0071] like Figures 3 to 8 As shown, the laminating unit 2 also includes an upper vent pipe 4, a lower vent pipe 5, and a venting device 6, wherein:

[0072] The upper air passage 4 is connected to the upper chamber, and the lower air passage 5 is connected to the air passage inside the heating plate, which in turn is connected to the lower chamber.

[0073] The ventilation device 6 includes a first air block 61, a first air inlet pipe 62, a second air inlet pipe 63, a first air inlet pipe 64, a second air inlet pipe 65, and an air extraction assembly 66, wherein:

[0074] A first air block 61 is disposed on the lower side of the laminating host 2, and a first air chamber 611 and a second air chamber 612 are provided within the first air block 61. A first air inlet pipe 62 connects the first air chamber 611 and the upper air passage 4. A second air inlet pipe 63 connects the second air chamber 612 and the lower air passage 5. The lower end of a first air inlet pipe 64 is connected to the first air block 61 and communicates with the first air chamber 611, while the upper end of the first air inlet pipe 64 extends upward into the insulation chamber. The first air inlet pipe 64 is configured to connect or disconnect the first air chamber 611 from the insulation chamber. The lower end of a second air inlet pipe 65 is connected to the first air block 61 and communicates with the second air chamber 612, while the upper end of the second air inlet pipe 65 extends upward into the insulation chamber. The second air inlet pipe 65 is configured to connect or disconnect the second air chamber 612 from the insulation chamber. An air extraction assembly 66 is configured to extract air from the first air chamber 611 and / or the second air chamber 612.

[0075] The optional operating procedures of the ventilation device 6 include:

[0076] When the laminating host 2 completes the closing process and the heating plate heats the photovoltaic module, the vacuum assembly 66 simultaneously evacuates air from the first air chamber 611 and the second air chamber 612. This causes the first air inlet pipe 62 to evacuate the upper chamber via the upper air passage 4, and the second air inlet pipe 63 to evacuate the lower chamber sequentially via the lower air passage 5 and the air channel within the heating plate, thereby removing air bubbles from the photovoltaic module within the lower chamber.

[0077] Next, the evacuation assembly 66 stops evacuating the first air chamber 611 while maintaining evacuation of the second air chamber 612. Simultaneously, the first air inlet pipe 64 connects the first air chamber 611 to the insulation chamber, allowing the insulating air in the insulation chamber to enter the first air chamber 611 via the first air inlet pipe 64, and finally fill the upper chamber via the first air inlet pipe 62 and the upper air passage 4, thus restoring the air pressure in the upper chamber to atmospheric pressure. Since the lower chamber remains under vacuum, a pressure difference is created between the upper and lower chambers, causing the pressure plate to deform or move downwards, thereby laminating the photovoltaic module.

[0078] After the photovoltaic module lamination process is completed, the second air inlet pipe 65 connects the second air chamber 612 and the insulation chamber, allowing the insulation air in the insulation chamber to enter the second air chamber 612 through the second air inlet pipe 65. The air then flows through the second air inlet pipe 63, the lower air passage 5, and the air channel within the heating plate into the lower chamber, thus restoring the air pressure in the lower chamber to atmospheric pressure. This balances the air pressure between the upper and lower chambers, ensuring the smooth opening of the lamination unit 2.

[0079] As can be seen, by configuring the ventilation device 6, it is possible to flexibly control the extraction and ventilation of the upper and lower chambers, thereby ensuring the smooth implementation of the lamination process. Specifically, since the upper ends of the first air inlet pipe 64 and the second air inlet pipe 65 both extend upwards into the insulation chamber, they can fill the upper and lower chambers with insulating air from the insulation chamber, preventing cold air from entering and affecting the insulation effect. The gas temperature in the insulation chamber is relatively high; the entry of gas from the insulation chamber into the upper and lower chambers reduces heat loss from the lamination unit 2.

[0080] like Figure 7 As shown, optionally, a first on / off valve 641 is provided on the first air inlet pipe 64. When the first on / off valve 641 is closed, it connects the first air chamber 611 and the insulation chamber; when the first on / off valve 641 is open, it isolates the first air chamber 611 from the insulation chamber. A second on / off valve 651 is provided on the second air inlet pipe 65. When the second on / off valve 651 is closed, it connects the second air chamber 612 from the insulation chamber; when the second on / off valve 651 is open, it isolates the second air chamber 612 from the insulation chamber.

[0081] By providing a first on / off valve 641 on the first air intake pipe 64, the first air intake pipe 64 can be connected to or disconnected from the first air chamber 611 by controlling the on / off state of the first on / off valve 641. Similarly, by providing a second on / off valve 651 on the second air intake pipe 65, the second air intake pipe 65 can be connected to or disconnected from the second air chamber 612 by controlling the on / off state of the second on / off valve 651.

[0082] Optionally, silencers 67 are provided at the upper openings (i.e., the air inlets located inside the insulation cavity) of both the first air inlet pipe 64 and the second air inlet pipe 65. In this way, the air intake of the first air inlet pipe 64 and the second air inlet pipe 65 can be silenced, thereby achieving the effect of noise reduction.

[0083] like Figure 7 As shown, optionally, the vacuum assembly 66 includes a vacuum pump (not shown), a second air block 661, a third air inlet pipe 662, a first control valve 663, and a second control valve 664. The second air block 661 contains a third air chamber, which is connected to the first air chamber 611 and the second air chamber 612 via the first control valve 663 and the second control valve 664, respectively. The first control valve 663 connects or disconnects the third air chamber from the first air chamber 611, and the second control valve 664 connects or disconnects the third air chamber from the second air chamber 612. The first end of the third air inlet pipe 662 is connected to the second air block 661 and communicates with the third air chamber, while the second end of the third air inlet pipe 662 is connected to the vacuum pump.

[0084] When simultaneous vacuuming of the upper and lower chambers is required, the first control valve 663 connects the third gas chamber to the first gas chamber 611, and the second control valve 664 connects the third gas chamber to the second gas chamber 612. Subsequently, the vacuum pump can simultaneously evacuate the first gas chamber 611 and the second gas chamber 612 via the third air inlet pipe 662 and the third gas chamber within the second gas block 661. This allows the first air inlet pipe 62 to evacuate the upper chamber via the upper air passage 4, and the second air inlet pipe 63 to evacuate the lower chamber sequentially via the lower air passage 5 and the air passage within the heating plate.

[0085] When it is necessary to stop evacuating the upper chamber (i.e., to fill the upper chamber with gas) and maintain evacuation of the lower chamber, the first control valve 663 is controlled to isolate the third gas chamber from the first gas chamber 611, while the second control valve 664 keeps the third gas chamber connected to the second gas chamber 612. Thus, the vacuum pump can only evacuate the second gas chamber 612 through the third gas inlet pipe 662 and the third gas chamber within the second gas block 661. Correspondingly, evacuation of the upper chamber stops, while evacuation of the lower chamber continues.

[0086] It can be seen that by configuring the vacuum assembly 66, it can simultaneously evacuate the upper and lower chambers, or evacuate only the lower or upper chamber.

[0087] Both the first control valve 663 and the second control valve 664 can be pneumatic butterfly valves.

[0088] As described above, the laminating machine 2 in this application can be a single-layer laminator with various existing structures. Figure 9 As shown, the laminating machine 2 includes an upper housing 21, a base 22, a lifting drive 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 second drive mechanism, wherein:

[0089] The upper housing 21 is located above the base 22. The lamination chamber and the pressure plate 27 are both located on the upper housing 21, while the heating plate 28 is located on the base 22. The lifting drive mechanism 29 is connected to the upper housing 21. The lifting drive mechanism 29 is used to drive the upper housing 21 to move up or down toward or away from the base 22, so as to open or close the lamination host 2.

[0090] 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 upper box 21 and the pressure plate 27.

[0091] The second high-temperature cloth 25 is fitted onto 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, thereby realizing the operation of the second high-temperature cloth 25. The second high-temperature cloth 25 covers the base 22 and the heating plate 28. The second high-temperature cloth 25 can support at least two photovoltaic modules 100 above the heating plate 28. The second high-temperature cloth 25 enables automatic loading and unloading of photovoltaic modules 100. The feeding end of the second high-temperature cloth 25 is the feeding end of the laminating host 2. The feeding end of the second high-temperature cloth 25 is adjacent to and flush with the feeding port 11 of the insulation chamber 1, so that the photovoltaic modules conveyed by the feeding conveyor line can enter the second high-temperature cloth 25 from the feeding port 11. The discharging end of the second high-temperature cloth 25 is the discharging end of the laminating host 2. The discharging end of the second high-temperature cloth 25 is adjacent to and flush with the discharging port 12 of the insulation chamber 1, so that the photovoltaic modules 100 after lamination on the second high-temperature cloth 25 can be output from the discharging port 12 to the discharging conveyor line.

[0092] When the laminating host 2 is closed, the pressure plate 27 laminates the photovoltaic module 100 that enters the lower chamber of the lamination chamber.

[0093] The first high-temperature cloth 23 covering the upper housing 21 and the pressure plate 27, and the second high-temperature cloth 25 covering the base 22 and the heating plate 28, can achieve anti-stick protection for the pressure plate 27 and the heating plate 28, and prevent the photovoltaic module 100 from sticking to the pressure plate 27 and the heating plate 28, which would affect the subsequent opening and unloading.

[0094] like Figure 9 As shown, optionally, the first drive mechanism and the second drive mechanism share a single motor 210, and the first roller group 24 and the second roller group 26 are linked together through a gear pair 211. Of course, the first drive mechanism and the second drive mechanism can also use separate motors to independently drive the first roller group 24 and the second roller group 26.

[0095] The lifting drive mechanism 29 can be a hydraulic cylinder, etc.

[0096] Optionally, the laminating host 2 also includes heat insulation curtains 212 disposed on both sides of the laminating host 2 along the width direction. The upper end of the heat insulation curtain 212 is fixed to the upper box 21, and the lower end of the heat insulation curtain 212 hangs down to the side of the heating plate 28 or the base 22, or the lower end of the heat insulation curtain 212 is connected to the heating plate 28 or the base 22, for example, the lower end of the heat insulation curtain 212 is attracted to the base 22 by a magnet.

[0097] The area of ​​the insulation curtain 212 should meet the following requirements: when the laminator 2 is opened, the upper box 21 moves upward away from the base 22, the insulation curtain 212 hangs on the upper box 21, and the lower end of the insulation curtain 212 can still hang down to the side of the heating plate 28 or the base 22. The insulation curtain 212 can insulate the space between the upper box 21 and the base 22 to improve the insulation effect of the lamination cavity, thereby further reducing the lamination energy consumption.
