Description

Technical Field

[0001] This application relates to the field of photovoltaic laminator equipment, and in particular to a smart temperature compensation device for a laminator. Background Technology

[0002] With the continuous advancement of photovoltaic (PV) module manufacturing technology, the adhesive bonding process in PV module production is becoming increasingly widespread. This involves bonding multiple layers of materials, such as tempered glass, solar cells, backsheets, aluminum alloys, and silicone, together to form a PV module. Different PV module models use different constituent materials, resulting in variations in the number of layers produced. After bonding, the PV modules require pressing to ensure adhesion, and laminators play a crucial role in this process. The use of laminators has improved the efficiency and quality of PV module production, enabling PV modules to better meet market demands and find wider application in fields such as solar power generation. It provides strong technical support for the development of the PV industry, promotes the effective utilization of solar energy resources, and is of great significance for advancing the development of clean energy.

[0003] A Chinese patent with authorization announcement number CN220180349U discloses a laminator, which includes a laminator main unit, a feeding platform main unit, and a discharging platform main unit, with the feeding platform main unit and the discharging platform main unit respectively located on both sides of the laminator main unit. The main process flow is as follows: photovoltaic modules at room temperature are fed into the laminator main unit through the feeding platform main unit, heated to the required lamination temperature, and then laminated and encapsulated. Finally, the modules are cooled to room temperature through the discharging platform main unit for the next process.

[0004] The aforementioned technologies have the following drawbacks: the photovoltaic modules flowing out of the laminator body will release a large amount of heat into the factory during the cooling process of the discharge table body to room temperature. This heat loss will become a waste of energy during the operation of the laminator, and therefore needs to be improved. Utility Model Content

[0005] In order to effectively utilize the heat dissipated by the photovoltaic modules flowing out of the laminator body during the cooling process to room temperature on the discharge platform body, and to use it for preheating the photovoltaic modules at the infeed platform body to compensate for temperature energy consumption, this application provides a laminator temperature intelligent compensation device.

[0006] A temperature intelligent compensation device for a laminator includes a laminator main unit, a feeding platform main unit, and a discharging platform main unit. The feeding platform main unit and the discharging platform main unit are respectively arranged on both sides of the laminator main unit. A suction hood is arranged on the side of the discharging platform main unit, and an air supply duct is arranged on the side of the feeding platform main unit. A conveying pipe is arranged between the suction hood and the air supply duct. The conveying pipe is equipped with an air supply mechanism for drawing air from the suction hood to the interior of the air supply duct. A preheating insulation cover is arranged on the top of the feeding platform main unit. The air supply duct is connected to the preheating insulation cover, and the preheating insulation cover is provided with a preheating air outlet.

[0007] By adopting the above technical solution, temperature sensors can be installed at various points inside the preheating insulation cover during actual use. These sensors collect temperatures at different locations to determine whether additional heating is needed inside the preheating insulation cover to preheat the photovoltaic modules. When additional preheating of the photovoltaic modules is required, the air supply mechanism is activated, allowing hot air from the discharge platform to be transported through the suction hood, conveying pipes, and air supply ducts into the preheating insulation cover. This promotes heat dissipation from the already laminated photovoltaic modules, reducing waste caused by heat loss. Furthermore, it effectively utilizes this heat to preheat the photovoltaic modules to be laminated, achieving efficient heat utilization. This reduces the temperature difference between the photovoltaic modules to be laminated and the actual lamination temperature, simplifying temperature control during the subsequent lamination process and resulting in higher stability of temperature-related process parameters during the actual lamination process.

[0008] Preferably, the preheating and heat preservation cover is provided with an adjustment window, a cover plate is rotatably installed inside the adjustment window, and the adjustment window is provided with an adjustment mechanism for driving the cover plate to rotate and achieving angle locking.

[0009] By adopting the above technical solution, based on the intelligent temperature compensation device of the laminator, an adjustment window, a rotatable cover and an adjustment mechanism are set up, which can flexibly adjust the ventilation in the preheating insulation cover as needed, and better achieve further control over the preheating of photovoltaic modules.

[0010] Preferably, the adjustment window is a stepped hole and a sealing strip is provided at the bottom. When the cover plate covers the adjustment window, the cover plate abuts against the sealing strip.

[0011] By adopting the above technical solution, the adjustment window is a stepped hole with a sealing strip at the bottom. When the cover plate seals the adjustment window, it abuts against the sealing strip, which can improve the sealing performance of the top of the adjustment window in the sealed state, reduce heat loss in this state, and improve the preheating effect on the photovoltaic module.

[0012] Preferably, the main body of the feeding platform includes a platform panel and a support frame. A heat exchange channel is provided inside the platform panel. The heat exchange channel is connected to a heat exchange air duct. The heat exchange air duct is connected to an air supply duct and a conveying pipeline through a three-way valve.

[0013] By adopting the above technical solution, based on the existing method of using hot air from the discharge platform to preheat photovoltaic modules, a heat exchange channel is set inside the feed platform panel. The heat exchange channel is connected to the air supply duct and conveying pipeline through heat exchange air ducts, three-way valves, etc., which allows the hot air from the discharge platform to enter the heat exchange channel. The hot air is then used to preheat the photovoltaic modules to be laminated in a non-contact manner through the platform panel. This makes it easy to select the preheating method as needed according to the actual situation, and realize the selection of two methods: direct preheating with hot air and heat exchange with the platform panel.

[0014] Preferably, the top of the inner wall of the heat exchange channel is provided with several extension grooves.

[0015] By adopting the above technical solution, the extended groove at the top of the inner wall of the heat exchange channel can increase the contact area between hot air and the platform, improve heat exchange efficiency, better preheat the photovoltaic modules to be laminated, further reduce the temperature difference between the photovoltaic modules to be laminated and the actual lamination temperature, reduce the difficulty of temperature control in the subsequent actual lamination process, and improve the stability of temperature-related process parameters.

[0016] Preferably, the conveying pipeline is connected in series with a filter, the filter including a housing and a filter element inside the housing, the inner cross-sectional area of ​​the housing is larger than the inner cross-sectional area of ​​the conveying pipeline, and both ends of the housing are open and connected in series with the conveying pipeline through an air inlet hopper and an air outlet hopper, respectively.

[0017] By adopting the above technical solution, a filter is connected in series in the conveying pipeline. The filter housing is open at both ends and connected in series with the air inlet hopper, air outlet hopper and conveying pipeline. The conveyed hot air can be filtered to reduce the impurities in the air from entering the subsequent system. The inner cross-sectional area of ​​the housing is larger than the inner cross-sectional area of ​​the conveying pipeline, which can reduce the flow velocity of hot air in the housing and improve the filtration effect.

[0018] Preferably, the filter element is plate-shaped, the side of the housing is provided with an installation port for inserting the filter element, the housing is rotatably provided with a sealing plate for sealing the installation port, and a spring is provided between the housing and the sealing plate to maintain the sealing plate's tendency to seal the installation port.

[0019] By adopting the above technical solution, based on the series filter in the conveying pipeline, a plate-shaped filter element, an installation port for inserting the filter element, a sealing plate, and a spring are set up to facilitate the installation and disassembly of the filter element, make it convenient to replace or clean the filter element, and the spring can keep the sealing plate in the state of sealing the installation port when no filter element is installed, ensuring the airtightness of the filter.

[0020] Preferably, a magnetic strip is provided on the inner side of the housing, and a magnetic strip is provided on the filter element that is magnetically attracted to the magnetic strip.

[0039] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0040] This application mainly adopts a scheme of conveying hot air from the discharge station to the infeed station to preheat the photovoltaic modules, which achieves the effect of effectively utilizing heat and reducing energy waste. The following is a further detailed description of this application. Example

[0041] Reference Figure 1 The intelligent temperature compensation device for a laminator provided in this application includes a laminator main unit 1, a feeding platform body 2, and a discharging platform body 3. The feeding platform body 2 and the discharging platform body 3 are respectively located on opposite sides of the laminator main unit 1. A suction hood 31 is installed on the side of the discharging platform body 3. The suction hood 31 is typically made of metal, such as stainless steel, which is corrosion-resistant and has high strength, ensuring it will not deform during long-term use. Its shape is generally trumpet-shaped, with the larger opening facing the discharging platform body 3, thus more effectively collecting hot air.

[0042] An air supply duct 21 is installed on the side of the main body 2 of the feeding platform. A conveying pipe 11 is installed between the suction hood 31 and the air supply duct 21. The conveying pipe 11 includes a pipe body and a connecting flange. In this embodiment, the pipe body can be a circular galvanized steel pipe, which has good sealing performance and corrosion resistance. In other embodiments, plastic pipes, such as PVC pipes, can also be used, which are lower in cost and easier to install. The connecting flange is generally made of carbon steel. In this embodiment, it is connected to the pipe body by welding. The connecting flange has multiple bolt holes for connecting to the suction hood 31 and the air supply duct 21 to ensure the sealing of the connection.

[0043] The conveying pipe 11 is equipped with an air supply mechanism 12 for drawing air from the suction hood 31 into the air supply duct 21. The air supply mechanism 12 can be a centrifugal fan with high air pressure and air volume, which can effectively draw air from the suction hood 31 into the air supply duct 21.

[0044] Reference Figure 2 and Figure 3 The top of the feeding platform body 2 is equipped with a preheating insulation cover 22, and the air supply duct 21 is connected to the preheating insulation cover 22. This arrangement effectively utilizes the heat dissipated by the photovoltaic modules at the discharging platform body 3 to preheat the photovoltaic modules at the feeding platform body 2, thus reducing energy waste. This is because, through the conveying pipe 11 and the air supply mechanism 12, the hot air at the discharging platform body 3 can be transported to the preheating insulation cover 22 of the feeding platform body 2, realizing the transfer and reuse of heat.

[0045] The preheating insulation cover 22 can be made of metal sheet, such as aluminum plate, with a smooth surface that is easy to clean. Alternatively, an insulation layer can be provided, which can be polyurethane foam material, offering good insulation performance and reducing heat loss. The insulation layer can be attached to the preheating insulation cover 22 by adhesive bonding or by using clips, facilitating disassembly and replacement. A preheating air outlet 23 is located on the side of the preheating insulation cover 22 furthest from the air supply duct 21.

[0046] The combination logic and effect of these components are as follows: the suction hood 31 collects hot air from the discharge platform body 3; the conveying pipe 11 transports the hot air to the air supply mechanism 12; the air supply mechanism 12 draws the hot air into the air supply duct 21; and then, through the air supply duct 21, the hot air is transported into the preheating insulation hood 22, and finally discharged from the preheating air outlet 23, preheating the photovoltaic modules at the infeed platform body 2. This combination allows heat to be transferred from the discharge platform body 3 to the infeed platform body 2, achieving effective utilization of heat.

[0047] Reference Figure 3Specifically, the main body 2 of the feeding platform includes a platform panel 24 and a support frame 25. The platform panel 24 is usually made of steel plate with a polished surface to ensure stable placement of the photovoltaic modules. The support frame 25 is generally welded from channel steel, providing high strength and stability. The platform panel 24 and the support frame 25 can be connected by bolts or welded for fixation. A heat exchange channel 26 is installed through the interior of the platform panel 24. Several extension grooves 27 are provided on the top of the inner wall of the heat exchange channel 26. The extension grooves 27 can increase the contact area between hot air and the inner wall of the heat exchange channel 26, improving heat exchange efficiency. The shape of the extension grooves 27 can be rectangular, triangular, etc., selected according to actual design requirements. A heat exchange air duct 28 is connected to the end of the heat exchange channel 26. The heat exchange air duct 28 is connected to the air supply duct 21 and the conveying pipe 11 via a three-way valve 29. The three-way valve 29 includes a valve body and a valve core. The valve body can be made of cast iron, providing high strength. The valve core can be made of stainless steel. The connection between the heat exchange air duct 28, the air supply air duct 21, and the delivery pipe 11 is controlled by rotating the valve core.

[0048] Reference Figure 3 and Figure 4 The preheating and insulation cover 22 is equipped with an adjustment window 4, within which a cover plate 41 is rotatably mounted. Furthermore, the adjustment window 4 also includes an adjustment mechanism (not shown in the figure) for driving the cover plate 41 to rotate and locking its angle. The adjustment window 4 has a frame structure, forming an internal window, which is generally rectangular and located on the top surface of the preheating and insulation cover 22. The frame can be made of aluminum alloy and is fixed to the preheating and insulation cover 22 with screws. Its function is to protect the edge of the window and provide a mounting base for the cover plate 41. The cover plate 41 can be made of plastic, which is lightweight and easy to rotate. Alternatively, it can be made of plexiglass, which has a certain degree of transparency, allowing for easy observation of the interior of the preheating and insulation cover 22. The cover plate 41 is connected to the frame of the adjustment window 4 via hinges, which are generally made of stainless steel to ensure durability. The adjustment mechanism includes a motor and a gear transmission device. The motor provides power, driving the cover plate 41 to rotate via the gear transmission device. The gear transmission device can precisely control the rotation angle of the cover plate 41 and can lock its angle. In other embodiments, an electric push rod can be used as the adjustment mechanism, and the rotation and automatic locking of the cover plate 41 can be achieved by extending and retracting the push rod. The inner side of the frame of the adjustment window 4 has stepped holes and a sealing strip 42 is provided at the bottom. When the cover plate 41 covers the adjustment window 4, the cover plate 41 and the sealing strip 42 abut against each other. The stepped hole design of the adjustment window 4 allows the cover plate 41 to fit better with the adjustment window 4 when closed, improving the sealing performance. The sealing strip 42 is generally made of rubber, which has good elasticity and sealing performance. The sealing strip 42 can be fixed to the bottom of the adjustment window 4 by adhesive.

[0049] Reference Figure 5 and Figure 6A filter 5 is connected in series with the conveying pipe 11. The filter 5 includes a housing 51 and a filter element 52 inside the housing 51. The inner cross-sectional area of ​​the housing 51 is larger than that of the inner cross-sectional area of ​​the conveying pipe 11. Both ends of the housing 51 are open and connected in series with the conveying pipe 11 through an air inlet duct 53 and an air outlet duct 54, respectively, to achieve a transition of cross-sectional area difference. The filter element 52 is plate-shaped, and the side of the housing 51 is provided with an installation port 55 for inserting the filter element 52. A magnetic strip 561 is provided inside the housing 51, and a magnetic strip 562 is provided on the filter element 52 that is magnetically attracted to the magnetic strip 561. In the installed state, the stability of the filter element 52 can be improved by magnetic adsorption.

[0050] Reference Figure 7 In addition, a sealing plate 57 is rotatably provided inside the housing 51 for sealing the mounting opening 55, and a spring 58 is provided between the housing 51 and the sealing plate 57 to maintain the sealing plate 57 in a tendency to seal the mounting opening 55. After the filter element 52 is replaced and removed, the sealing plate 57 can automatically close the mounting opening 55, thereby reducing the loss of hot air.

[0051] The implementation principle of this embodiment is as follows: Through a reasonable structural design, the heat dissipated by the photovoltaic modules at the discharge platform body 3 is collected and transported to the infeed platform body 2 for preheating the photovoltaic modules. The temperature inside the preheating insulation cover 22 can be adjusted according to actual needs via the adjustment window 4 and adjustment mechanism, improving the flexibility of temperature regulation. The stepped holes and sealing strip 42 prevent hot air leakage and ensure stable temperature inside the preheating insulation cover 22. The heat exchange channel 26 and heat exchange duct 28 further utilize the heat of the hot air to heat the platform panel 24, and the three-way valve 29 flexibly controls the direction of hot air flow. The extension groove 27 optimizes the heat exchange effect of the heat exchange channel 26. The filter 5 filters impurities in the air. Compared with existing technologies, this reduces energy waste during the operation of the laminator and improves energy utilization efficiency. This design not only reduces production costs but also conforms to the concept of energy conservation and environmental protection, playing a positive role in promoting the sustainable development of the photovoltaic module manufacturing industry.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
