Description

An airbag contact laminator and its constituent single-layer dual-cavity laminator and system Technical Field

[0001] This invention relates to the field of laminator technology, and more specifically to an airbag contact laminator and a single-layer double-cavity laminator and system thereof. Background Technology

[0002] A solar cell module laminator is one of the essential pieces of equipment for encapsulating solar cell modules. During the manufacturing process of solar cell modules, the laminator is needed to press the encapsulant film, solar cells, tempered glass, and backsheet into a rigid whole under high temperature and vacuum conditions.

[0003] However, the laminators currently suffer from the following main technical problems:

[0004] 1) Currently, laminators all use silicone plates for lamination. For example, patent CN114834138B, entitled "A Fully Automatic Stackable Multilayer Laminator," discloses two lamination components (upper and lower chambers) arranged adjacent to each other. When pressed together, a first vacuum chamber and a second vacuum chamber are formed between them, separated by the silicone plates. On the one hand, lamination is performed using two identical lamination components (upper and lower chambers), resulting in numerous parts and a complex structure. On the other hand, the silicone plates undergo downward stretching during vacuuming and inflation, making them prone to damage and requiring frequent replacement and maintenance, thus increasing costs.

[0005] 2) Currently, most laminators are single-cavity laminators, and each cavity laminates only one solar panel. On the one hand, if a single cavity is damaged, it will lead to production interruption, resulting in low efficiency and low reliability; on the other hand, since it only undergoes lamination once, the quality is relatively low.

[0006] Therefore, providing a simple, reliable, and efficient airbag contact laminator and its constituent single-layer double-cavity laminator and system is a problem that urgently needs to be solved by those skilled in the art.

[0007] Summary of the Invention

[0008] In view of the above, the present invention provides an airbag contact laminator and a single-layer dual-cavity laminator and system thereof, so as to at least solve one of the technical problems mentioned in the background section above.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An airbag contact laminator includes a frame, an airbag heating and pressing device, multiple hydraulic cylinders, a lower heating plate, and a vacuuming and inflation system. The airbag heating and pressing device is mounted on the frame via the multiple hydraulic cylinders around its periphery. The lower heating plate is horizontally fixed on a support frame of the frame and corresponds to the position of the airbag heating and pressing device above it, thereby forming a vacuum lamination chamber when the airbag heating and pressing device presses against the lower heating plate. The vacuuming and inflation system is connected to the airbag heating and pressing device and communicates with the vacuum lamination chamber through the lower heating plate.

[0011] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0012] The hydraulic cylinder drives the airbag heating and pressing device to rise and fall. When it presses against the lower heating plate, a vacuum lamination chamber is formed between the two. That is, only one vacuum lamination chamber is used to achieve the lamination of solar cell modules, eliminating the need for the upper box structure and silicone plate, simplifying the structure, avoiding frequent replacement and maintenance of silicone plate, saving costs, and improving work efficiency.

[0013] Furthermore, the airbag-type heating and pressing device includes a side frame, an upper heating plate, multiple airbags, an aluminum plate, and a silicone pad. The cylinder body of each hydraulic cylinder is vertically mounted on the frame, and the telescopic rod of each hydraulic cylinder is fixedly connected to the side frame through a connecting frame. When the bottom end of the side frame presses against the lower heating plate, a vacuum lamination chamber is formed inside it. The upper heating plate is located at the top of the side frame and is connected by a fastening assembly. The tops of the multiple airbags are fixedly connected to the upper heating plate and are evenly distributed. The vacuuming and inflation system is connected and communicates with the multiple airbags. The aluminum plate is installed at the bottom end of the multiple airbags. The silicone pad is laid on the bottom of the aluminum plate.

[0014] The beneficial effect of adopting the above-mentioned further technical solution is that when the bottom end of the side frame presses against the lower heating plate, the lower heating plate and the upper heating plate begin to heat up. Then, when the vacuuming and inflation system begins to inflate the airbag, the compressed air will give pressure to the airbag, forcing it to move the aluminum plate and silicone pad downwards until they are pressed against the solar cell module for lamination.

[0015] Furthermore, the top and bottom ends of the side frame are each provided with a sealing groove, and a sealing ring is installed in each of the two sealing grooves.

[0016] The beneficial effect of adopting the above-mentioned further technical solution is to improve the sealing between the side frame and the upper heating plate, and between the side frame and the lower heating plate when they are pressed together.

[0017] Furthermore, the vacuuming and inflation system includes a vacuum pump, a vacuum connection pipe, a first vacuum pipe, a second vacuum pipe, a corrugated telescopic pipe, a vacuum inflation pipe, and a compressed air system. One end of the vacuum connection pipe is connected to the vacuum pump, and the other end of the vacuum connection pipe is connected to the first vacuum pipe and the second vacuum pipe respectively via a tee. A first solenoid valve is installed on the first vacuum pipe, and a second solenoid valve is installed on the second vacuum pipe. Multiple extension ends of the first vacuum pipe are connected to the vacuum lamination chamber through multiple air extraction holes of the lower heating plate. The extension ends of the second vacuum pipe are connected to the vacuum inflation pipe through the corrugated telescopic pipe. Multiple extension ends of the vacuum inflation pipe pass through the upper heating plate and are connected to multiple airbags. A third solenoid valve is installed on the vacuum inflation pipe. The compressed air system is connected to the vacuum inflation pipe through the second vacuum pipe and the corrugated telescopic pipe, and the compressed air system is connected to the second vacuum pipe near its output end.

[0018] The beneficial effects of adopting the above-mentioned further technical solution are as follows: when the first solenoid valve is opened, the vacuum pump performs a vacuuming operation in the vacuum lamination chamber through the vacuum connection pipeline and the first vacuum pipeline; when the second and third solenoid valves are opened, the vacuum pump performs a vacuuming operation in each airbag through the vacuum connection pipeline, the second vacuum pipeline, the corrugated telescopic pipe and the vacuum inflation pipeline; when the second solenoid valve is closed and the third solenoid valve is opened, the compressed air system fills each airbag with compressed gas through the second vacuum pipeline, the corrugated telescopic pipe and the vacuum inflation pipeline, thereby realizing the integration of vacuuming and inflation pipelines.

[0019] Furthermore, the upper heating plate includes three upper heating plate units, which are arranged sequentially along the top of the side frame; correspondingly, the aluminum plate includes three aluminum plate units, which are respectively installed on the bottom of multiple airbags on the three upper heating plate units; the silicone pad includes three silicone pad units, which are respectively laid and fixed on the bottom of the three aluminum plate units; the vacuum inflation pipeline includes three vacuum inflation pipeline units and a main input pipeline, the top end of the corrugated telescopic tube is connected to the three vacuum inflation pipeline units through the main input pipeline, and each vacuum inflation pipeline unit is equipped with the third solenoid valve.

[0020] The beneficial effects of adopting the above-mentioned further technical solution are that the lamination area is divided into three zones, which can simultaneously laminate multiple solar panels, improving efficiency. Furthermore, if one airbag is damaged, lamination can continue in other locations, improving reliability. In addition, users can choose the lamination area and the number of modules to be laminated according to their own situation, improving applicability.

[0021] Furthermore, both the upper heating plate and the lower heating plate are electrically connected to an electromagnetic heating control cabinet located outside the frame via multiple thermal wires.

[0022] The beneficial effect of adopting the above-mentioned further technical solution is that the electromagnetic heating component is external, which facilitates its maintenance and avoids disassembling the heating plate and internal maintenance operations of the frame.

[0023] An airbag contact type single-layer dual-cavity laminator includes a conveying mechanism and two airbag contact type laminators as described above, the two airbag contact type laminators being arranged sequentially from left to right and aligned; the conveying mechanism is mounted on the frame of the two airbag contact type laminators to form a conveying channel between the side frame and the lower heating plate.

[0024] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0025] The two airbag contact laminators form two chambers. One chamber is mainly used for vacuuming and degassing, while the second chamber performs a film curing process based on the first chamber. Through two laminations, product quality is improved, and production efficiency is increased at the same time.

[0026] Furthermore, the conveying mechanism includes an upper input drive roller assembly, a lower input drive roller assembly, an upper output drive roller assembly, a lower output drive roller assembly, an upper chain drive mechanism, a lower chain drive mechanism, an upper high-temperature cloth rod, a lower high-temperature cloth rod, an upper high-temperature cloth, and a lower high-temperature cloth. The upper input drive roller assembly and the upper output drive roller assembly are respectively installed on the input side and the output side of the frame, and are connected by the upper chain drive mechanism. The lower input drive roller assembly and the lower output drive roller assembly are respectively installed on the input side and the output side of the frame, and are connected by the lower chain drive mechanism. The transmission mechanism is connected, and the lower power roller group at the input end is located below the upper power roller group at the input end, and the lower power roller group at the output end is located below the upper power roller group at the output end; the upper high-temperature cloth rod is fixed on the upper chain transmission mechanism; the lower high-temperature cloth rod is fixed on the lower chain transmission mechanism; the upper high-temperature cloth is fixed on the upper high-temperature cloth rod and surrounds the airbag heating and pressing device; the lower high-temperature cloth is fixed on the lower high-temperature cloth rod and surrounds the lower heating plate, thereby forming a conveying channel between the upper high-temperature cloth and the lower high-temperature cloth.

[0027] Furthermore, the airbag contact type single-layer double-cavity laminator also includes a transition plate, which is installed at the junction of the two frames and located inside the lower high-temperature fabric.

[0028] The beneficial effect of adopting the above-mentioned further technical solutions is to improve the reliability of transportation.

[0029] An airbag contact type single-layer dual-cavity laminator system includes a feed platform, a discharge platform, and the airbag contact type single-layer dual-cavity laminator as described above. The feed platform and the discharge platform are located on the input side and the output side of the airbag contact type single-layer dual-cavity laminator, respectively.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] As shown in Figures 1-13, this invention discloses an airbag contact laminator, including a frame 1, an airbag heating and pressing device 2, multiple hydraulic cylinders 3, a lower heating plate 4, and a vacuuming and inflation system 5. The airbag heating and pressing device 2 is mounted on the frame 1 via the multiple hydraulic cylinders 3. The lower heating plate 4 is horizontally fixed on the support frame 11 of the frame 1 and corresponds to the position of the airbag heating and pressing device 2 above it, thereby forming a vacuum lamination chamber when the airbag heating and pressing device 2 presses against the lower heating plate 4. The vacuuming and inflation system 5 is connected to the airbag heating and pressing device 2 and communicates with the vacuum lamination chamber through the lower heating plate 4. In this invention, the hydraulic cylinders 3 drive the airbag heating and pressing device 2 to rise and fall. When it presses against the lower heating plate 4, a vacuum lamination chamber is formed between them. This means that only one vacuum lamination chamber is used to achieve solar cell module lamination, eliminating the need for an upper box structure and silicone plate, simplifying the structure, avoiding frequent replacement and maintenance of silicone plate, saving costs, and improving work efficiency.

[0048] Specifically, the airbag-type heating and pressing device 2 includes a side frame 21, an upper heating plate 22, multiple airbags 23, an aluminum plate 24, and a silicone pad 25. The cylinder body of each hydraulic cylinder 3 is vertically mounted on the frame 1. The telescopic rod of each hydraulic cylinder 3 is fixedly connected to the side frame 21 via a connecting frame 6. When the bottom end of the side frame 21 presses against the lower heating plate 4, a vacuum lamination chamber is formed inside it. The upper heating plate 22 is located on top of the side frame 21 and is connected via a fastening assembly 7. The tops of the multiple airbags 23 are all fixedly connected to the upper heating plate 22 and... The vacuum and inflation system 5 is evenly distributed and connected to multiple airbags 23; aluminum plate 24 is installed at the bottom end of multiple airbags 23; silicone pad 25 is laid on the bottom of aluminum plate 24. During operation, when the bottom end of side frame 21 presses against the lower heating plate 4, the lower heating plate 4 and upper heating plate 22 start to heat up. Then, when the vacuum and inflation system 5 starts to inflate the airbags 23, the compressed air will give pressure to the airbags 23, forcing them to move the aluminum plate 24 and silicone pad 25 downwards until they are pressed against the solar cell module for lamination.

[0049] Specifically, the airbag 23 includes an airbag body 231, an upper flange 232, and a lower flange 233 connected as one unit. The upper flange 232 is connected to the upper heating plate 22 by bolts, and the lower flange 233 is connected to the aluminum plate 24 by bolts. Of course, the airbag body 231 is made of high-temperature resistant flexible material to improve heat resistance.

[0050] To further optimize the technical solution of the present invention, the top and bottom ends of the side frame 21 are provided with sealing grooves, and sealing rings are installed in both sealing grooves to improve the sealing between the side frame 21 and the upper heating plate 22, and between the side frame 21 and the lower heating plate 4 when they are pressed together.

[0051] To further optimize the technical solution of the present invention, and to protect the internal components of the frame 1 from damage, a protective plate can be installed on the periphery of the frame 1.

[0052] Specifically, the vacuuming and inflation system 5 includes a vacuum pump 51, a vacuum connection pipe 52, a first vacuum pipe 53, a second vacuum pipe 54, a corrugated telescopic pipe (not shown in the figure), a vacuum inflation pipe 55, and a compressed air system 56.

A first solenoid valve 531 is installed on the first vacuum pipe 53, and a second solenoid valve 541 is installed on the second vacuum pipe 54. Multiple extensions of the first vacuum pipe 53 are connected to the vacuum lamination chamber through multiple air extraction holes of the lower heating plate 4. The extensions of the second vacuum pipe 54 are connected to the vacuum inflation pipe 55 via a corrugated telescopic pipe. Multiple extensions of the vacuum inflation pipe 55 pass through the upper heating plate 22 and are connected to multiple air bags 23. A third solenoid valve 551 is installed on the air inflation line 55; the compressed air system 56 is connected to the vacuum inflation line 55 through the second vacuum line 54 and the corrugated telescopic tube, and the compressed air system 56 is connected to the second vacuum line 54 near the output end. During operation, the first solenoid valve 531 is opened, and the vacuum pump 51 performs a vacuuming operation in the vacuum lamination chamber through the vacuum connection line 52 and the first vacuum line 53. The second solenoid valve 541 and the third solenoid valve 551 are opened, and the vacuum pump 51 performs a vacuuming operation in each airbag 23 through the vacuum connection line 52, the second vacuum line 54, the corrugated telescopic tube and the vacuum inflation line 55. The second solenoid valve 541 is closed, and the third solenoid valve 551 is opened. The compressed air system 56 fills each airbag 23 with compressed gas through the second vacuum line 54, the corrugated telescopic tube and the vacuum inflation line 55, realizing the integration of vacuuming and inflation lines.

[0053] Specifically, the upper heating plate 22 includes three upper heating plate units, which are arranged sequentially along the top of the side frame 21; correspondingly, the aluminum plate 24 includes three aluminum plate units, which are respectively installed on the bottom of multiple airbags 23 on the three upper heating plate units. In this embodiment, 15 airbags 23 form a group; the silicone pad 25 includes three silicone pad units, which are respectively laid and fixed on the bottom of the three aluminum plate units; the vacuum inflation pipeline 55 includes three vacuum inflation pipeline units 552. The main input pipe 553 connects the top of the corrugated telescopic tube to three vacuum inflation pipe units 552. Each vacuum inflation pipe unit 552 is equipped with a third solenoid valve 551, thereby dividing the lamination area into three zones. Multiple solar panels can be laminated simultaneously, improving efficiency. If one airbag 23 is damaged, lamination can continue in other areas, improving reliability. Users can also choose the lamination area and the number of modules to be laminated according to their own needs, improving applicability.

[0054] To further optimize the technical solution of the present invention, the upper heating plate 22 and the lower heating plate 4 are electrically connected to the electromagnetic heating control cabinet 8 located outside the frame 1 through multiple heat wires. By placing the electromagnetic heating components externally, it is convenient to maintain and repair them, avoiding the need to disassemble the heating plates and perform maintenance operations inside the frame 1.
