Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic module manufacturing equipment, in particular to a laminating device. BACKGROUND

[0002] In the laminating process of photovoltaic modules, a plurality of photovoltaic modules are usually sent into a laminating device together, and a large silicone plate is used to simultaneously laminate the plurality of photovoltaic modules. Although this laminating method can improve production efficiency, it also brings significant potential risks. Specifically, since the same large silicone plate is used to simultaneously laminate a plurality of photovoltaic modules, once the silicone plate is damaged, the vacuum sealing will be damaged, and then the entire batch of photovoltaic modules will have laminating bubbles, and ultimately can only be scrapped. More seriously, when producing single-glass photovoltaic modules, if the glass of any photovoltaic module is broken during the laminating process, the glass fragments will not only directly damage the photovoltaic module, but also may splash and adhere to other photovoltaic modules, causing other photovoltaic modules to break or the laminating effect to be substandard, which will also result in the scrapping of the photovoltaic modules. Therefore, the current laminating device greatly increases the uncertainty and scrappage rate in the production process. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a laminating device to reduce the uncertainty and scrappage rate in the laminating process.

[0004] The present application provides a laminating device, comprising:

[0005] a support plate for supporting photovoltaic modules;

[0006] a soft plate arranged above the support plate, the soft plate being capable of being attached to the support plate or being separated from the support plate; and

[0007] a mounting plate arranged above the soft plate, the mounting plate being arranged in a spaced-apart manner with the soft plate;

[0008] an isolation mechanism arranged between the mounting plate and the soft plate, the isolation mechanism comprising a driving member and an isolation frame, the driving member being arranged on the mounting plate and connected with the isolation frame, the isolation frame being a hollow frame structure, the isolation frame being capable of being pressed against the soft plate or being separated from the soft plate under the driving of the driving member, and when the isolation frame is pressed against the soft plate, the isolation frame surrounds the outer periphery of the photovoltaic modules, so that the part of the soft plate located in the isolation frame and the support plate jointly enclose a sealing chamber for sealing a single photovoltaic module.

[0009] The technical solutions are further described as follows:

[0010] In one of the embodiments, the isolating frame is provided with a pressure sensor on the side close to the soft plate, and the pressure sensor is used to detect the pressure value between the isolating frame and the soft plate.

[0011] In one of the embodiments, the number of the pressure sensors is multiple, and all the pressure sensors are arranged on the side of the isolating frame close to the soft plate in a circumferential direction of the isolating frame.

[0012] In one of the embodiments, the isolating mechanism further comprises a reinforcing rod, which is connected to the side of the isolating frame close to the mounting plate, and the reinforcing rod is arranged across the isolating frame.

[0013] In one of the embodiments, the isolating frame is a rectangular frame structure, and the reinforcing rod comprises a longitudinal rod and a transverse rod arranged in intersection, the longitudinal rod extends in a direction parallel to the long side of the isolating frame, and the transverse rod extends in a direction parallel to the short side of the isolating frame.

[0014] In one of the embodiments, the driving member comprises an electric telescopic rod, one end of the electric telescopic rod is connected to the mounting plate, and the other end is connected to the side of the isolating frame close to the mounting plate.

[0015] In one of the embodiments, the number of the electric telescopic rods is multiple, and all the electric telescopic rods are arranged on the side of the isolating frame close to the mounting plate in a circumferential direction of the isolating frame.

[0016] In one of the embodiments, the laminating device further comprises a conveying mechanism for conveying the photovoltaic module, and the support plate is detachably arranged on the conveying mechanism.

[0017] In one of the embodiments, the isolating frame is a metal material piece; and / or, the soft plate is a silica gel material piece; and / or, the support plate is a cloth piece.

[0018] In one of the embodiments, the number of the isolating mechanisms is multiple, and all the isolating mechanisms are arranged in sequence in a length direction of the mounting plate.

[0019] In the aforementioned lamination apparatus, an isolation mechanism is installed between the mounting plate and the flexible plate. By inflating the space between them, the flexible plate moves downwards and adheres to the support plate and photovoltaic module. Then, the driving component of the isolation mechanism presses an isolation frame against the flexible plate, surrounding the photovoltaic module. This allows the portion of the flexible plate within the isolation frame to form a sealed chamber with the support plate, providing sealing protection for the photovoltaic module. Even if other areas of the flexible plate are damaged, the sealing of the chamber remains unaffected, ensuring the lamination effect of the photovoltaic module within the sealed chamber. This avoids the problem of lamination bubbles appearing in the entire batch of photovoltaic modules if the flexible plate is damaged. Furthermore, if glass fragments appear in the photovoltaic module within the sealed chamber during lamination, they can be contained within the sealed chamber, preventing them from splashing and adhering to other photovoltaic modules, causing breakage or substandard lamination. This reduces uncertainty and the scrap rate during the photovoltaic module lamination process. Attached Figure Description

[0034] One embodiment of this application provides a lamination apparatus for laminating a photovoltaic module 30. Specifically, see [link to specific embodiment]. Figures 1 to 3 One embodiment of the lamination apparatus includes a support plate 11, a flexible plate 12, a mounting plate 13, and an isolation mechanism 20. The support plate 11 is used to support the photovoltaic module 30. The flexible plate 12 is disposed above the support plate 11, and a first air chamber 111 is formed between the flexible plate 12 and the support plate 11. The flexible plate 12 can be attached to the support plate 11 or separated from the support plate 11. The mounting plate 13 is disposed above the flexible plate 12, and a second air chamber 121 is formed between the mounting plate 13 and the flexible plate 12 by a gap. The isolation mechanism 20 is disposed in the second air chamber 121. The isolation mechanism 20 includes a driving member 22 and an isolation frame 21. The driving member 22 is disposed on the mounting plate 13 and connected to the isolation frame 21. The isolation frame 21 is a hollow frame structure. The isolation frame 21 can be pressed against the flexible plate 12 or separated from the flexible plate 12 under the drive of the driving member 22. When the isolation frame 21 is pressed against the flexible plate 12, the isolation frame 21 is sleeved on the outer periphery of the photovoltaic module 30, so that the part of the flexible plate 12 located inside the isolation frame 21 and the support plate 11 together form a sealed chamber for sealing a single photovoltaic module 30.

[0035] For example, the working process of the above-mentioned lamination device is as follows: First, the photovoltaic module 30 to be laminated is transported into the first air chamber 111. Then, the first air chamber 111 and the second air chamber 121 are evacuated to remove the air from the first air chamber 111, the second air chamber 121, and the photovoltaic module 30. Then, air is injected into the second air chamber 121 so that the air pressure in the second air chamber 121 is greater than the air pressure in the first air chamber 111, so that the flexible plate 12 moves downward and adheres to the support plate 11, thereby pressing the photovoltaic module 30 on the support plate 11. At the same time, the driving member 22 drives the isolation frame 21 to move downward to press against the flexible plate 12 and surround the photovoltaic module 30, so that the part of the flexible plate 12 located in the isolation frame 21 and the support plate 11 together form a sealed chamber to seal and protect the photovoltaic module 30 therein. Maintain the position of the isolation frame 21 until the entire lamination process is completed. Then, drive the isolation frame 21 to rise back to the initial position and break the vacuum in the first air chamber 111, so that the silicone plate separates from the support plate 11. At this time, the laminated photovoltaic module 30 can be taken out.

[0036] In the above-mentioned lamination device, by setting an isolation mechanism 20 in the second air chamber 121 between the mounting plate 13 and the flexible plate 12, the flexible plate 12 moves downward and adheres to the support plate 11 and the photovoltaic module 30 after being inflated into the second air chamber 121. Then, the driving component 22 of the isolation mechanism 20 drives the isolation frame 21 to press against the flexible plate 12 and surround the photovoltaic module 30. This allows the part of the flexible plate 12 located in the isolation frame 21 to form a sealed chamber together with the support plate 11, thereby sealing and protecting the photovoltaic module 30 inside. In this way, even if other areas of the flexible plate 12 are damaged, the sealing performance of the sealed chamber will not be affected, ensuring the lamination effect of the photovoltaic module 30 in the sealed chamber and avoiding the problem of lamination bubbles in the entire batch of photovoltaic modules 30 once the flexible part is damaged. Meanwhile, when glass fragments appear in the photovoltaic module 30 in the sealed chamber during the lamination process, the glass fragments can be sealed in the sealed chamber to prevent them from splashing and adhering to other photovoltaic modules 30, causing other photovoltaic modules 30 to break or the lamination effect to fail to meet the standard, thereby reducing the uncertainty and scrap rate of the photovoltaic module 30 during the lamination process.

[0037] Optionally, in one embodiment, a pressure sensor (not shown) is provided on the side of the isolation frame 21 near the flexible plate 12. The pressure sensor is used to detect the pressure value between the isolation frame 21 and the flexible plate 12. Specifically, during the process of the isolation frame 21 pressing against the flexible plate 12, the pressure sensor continuously monitors the pressure value between the isolation frame 21 and the flexible plate 12 and feeds this pressure data back to the system in real time. When the pressure value monitored by the system reaches a preset value that ensures the sealing chamber has good airtightness, the drive component 22 stops driving the isolation frame 21 to move downward and maintains the current state, thereby ensuring that the sealing chamber maintains good airtightness during the lamination process.

[0038] Furthermore, multiple pressure sensors are used, all of which are arranged circumferentially around the isolation frame 21 on the side of the isolation frame 21 closest to the flexible plate 12. By simultaneously monitoring the pressure value between the isolation frame 21 and the flexible plate 12 using multiple pressure sensors, the monitoring accuracy is improved.

[0039] See Figure 3 Optionally, in one embodiment, the isolation mechanism 20 further includes a reinforcing rod 23, which is connected to the side of the isolation frame 21 near the mounting plate 13 and spans across the isolation frame 21. The reinforcing rod 23 can structurally reinforce the isolation frame 21 and prevent deformation of the isolation frame 21.

[0040] Specifically, in one embodiment, the isolation frame 21 is a rectangular frame structure to match the rectangular photovoltaic module 30. Further, the reinforcing rod 23 includes intersecting longitudinal rods 231 and transverse rods 232. The longitudinal rods 231 extend parallel to the long side of the isolation frame 21, and the transverse rods 232 extend parallel to the short side of the isolation frame 21. Thus, the longitudinal rods 231 support the two short sides of the isolation frame 21, and the transverse rods 232 support the two long sides of the isolation frame 21, thereby increasing the strength of the isolation frame 21 and preventing deformation.

[0041] Furthermore, multiple longitudinal bars 231 and multiple transverse bars 232 are provided, with multiple longitudinal bars 231 arranged in parallel and multiple transverse bars 232 arranged in parallel, thus further improving the strength of the isolation frame 21.

[0042] See Figure 1 as well as Figure 3Optionally, in one embodiment, the drive element 22 includes an electrically operated telescopic rod, one end of which is connected to the mounting plate 13, and the other end is connected to the side of the isolation frame 21 near the mounting plate 13. Thus, extending the electrically operated telescopic rod causes the isolation frame 21 to press against the flexible plate 12, and retracting the electrically operated telescopic rod causes the isolation frame 21 to return to its initial position. Understandably, in other embodiments, the drive element 22 may be a pneumatic cylinder or a hydraulic cylinder, etc.

[0043] In one embodiment, for example, there are multiple electric telescopic rods, all of which are arranged circumferentially around the isolation frame 21 on the side of the isolation frame 21 closest to the mounting plate 13. By simultaneously driving the isolation frame 21 to rise and fall with multiple electric telescopic rods, the force on the isolation frame 21 is balanced, and the isolation frame 21 is kept horizontal during the rising and falling process, thereby ensuring the sealing of the sealed chamber.

[0044] Optionally, in one embodiment, the laminating apparatus further includes a conveying mechanism (not shown) for conveying the photovoltaic module 30. This conveying mechanism enables automated loading and unloading of the photovoltaic module 30, improving production efficiency. Furthermore, the support plate 11 is detachably mounted on the conveying mechanism, facilitating maintenance and replacement. Exemplarily, the support plate 11 is a fabric component, such as a high-temperature resistant fabric, which covers the conveyor belt of the conveying mechanism to support the photovoltaic module 30.

[0045] In one embodiment, the isolation frame 21 is made of metal, thereby improving its structural strength. The flexible plate 12 is made of silicone, thereby ensuring that the flexible plate 12 has good elastic deformation capability.

[0046] See Figure 2 Optionally, there may be multiple isolation mechanisms 20, all of which are arranged sequentially along the length of the mounting plate 13. This allows multiple sealing cavities to be formed between the flexible plate 12 and the support plate 11 at once, sealing each photovoltaic module 30 accordingly and further improving the yield of the photovoltaic modules 30 in the lamination process. Exemplarily, in one embodiment, the isolation frames 21 of all isolation mechanisms 20 are spaced apart along the length of the mounting plate 13, and each isolation frame 21 is driven by an independent drive element 22. Understandably, in other embodiments, the isolation frames 21 of all isolation mechanisms 20 may also be connected as a single unit, with all isolation frames 21 driven uniformly by the same drive element 22.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
