Description

Technical Field

[0001] This utility model relates to the field of photovoltaic industry technology, and more specifically to a laminating device for a single-cavity adhesive sheet pressing a two-cavity flat plate pressing module. Background Technology

[0002] With the rapid development of the photovoltaic industry, increasingly higher demands are being placed on the production efficiency and quality of photovoltaic modules. In the manufacturing process of photovoltaic modules, lamination plays a crucial role. The core objective of this process is to use heating and pressurization to tightly bond key materials such as solar cells, encapsulant films, and glass together to form a robust and stable whole, thereby ensuring the module can operate stably for a long time under various environmental conditions.

[0003] However, the currently widely used traditional lamination process is mainly based on single-cavity lamination technology for adhesive sheets. This technology has many obvious defects and shortcomings, which seriously restrict the further improvement of the overall efficiency and product quality of photovoltaic module production.

[0004] First, traditional single-cavity lamination technology for photovoltaic panels only has one lamination chamber. In actual production, to achieve the desired lamination effect, multiple lamination operations are often required for the modules. This repetitive lamination process not only significantly reduces production efficiency, but also increases the risk of quality fluctuations during production because each lamination requires precise control of process parameters. This results in inconsistent quality of the produced photovoltaic modules, making it difficult to meet the market's stable demand for high-quality photovoltaic modules.

[0005] Secondly, the production cycle of traditional single-cavity lamination technology is no longer suitable for the large-scale, high-speed production lines required by modern photovoltaic (PV) companies. In today's fiercely competitive market, PV companies need to continuously improve production efficiency to reduce production costs and enhance market competitiveness. However, the low efficiency of traditional lamination technology has become a bottleneck restricting the improvement of production efficiency for PV companies, seriously affecting their economic benefits and development speed.

[0006] Furthermore, the traditional single-cavity lamination process using adhesive sheets is limited by the quality and material properties of the adhesive sheets themselves, resulting in high maintenance costs. As a key component in the lamination process, the quality and performance of the adhesive sheet directly affect the lamination effect. However, adhesive sheets are prone to cracking and damage during long-term use. Once a adhesive sheet malfunctions, the entire lamination process will be forced to stop, which will not only cause production delays but also increase the cost of equipment maintenance and replacement. Frequent maintenance and replacement of adhesive sheets not only consumes a significant amount of time and manpower but also brings many inconveniences to the company's production management, further impacting the company's production efficiency.

[0007] Furthermore, traditional single-cavity lamination technology for adhesive sheets also presents significant challenges in module yield. Issues such as residual air bubbles and uneven adhesive film flow during lamination can lead to internal defects in the modules, reducing their photoelectric conversion efficiency and lifespan. This low yield forces companies to invest more raw materials and energy in production, while also increasing the cost of handling defective products, which is extremely detrimental to the company's sustainable development.

[0008] In summary, the traditional single-cavity lamination process for photovoltaic (PV) modules faces numerous challenges in terms of production efficiency, quality stability, maintenance costs, and module yield. These problems not only affect the production quality of PV modules and the economic benefits for enterprises but also hinder the further development of the PV industry. Therefore, developing a novel lamination process to overcome the shortcomings of existing traditional single-cavity lamination technology, improve the production efficiency and quality of PV modules, and reduce production costs is of significant practical importance and has broad application prospects for promoting the sustainable and healthy development of the PV industry. Utility Model Content

[0009] In view of this, the present invention provides a laminating device for a single-cavity adhesive sheet pressing a two-cavity flat plate pressing assembly, which aims to solve the above-mentioned technical problems.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A laminating device for a single-cavity sheet laminating and a two-cavity flat laminating assembly includes a sheet laminating mechanism and a flat laminating mechanism arranged sequentially, with a conveying mechanism for connecting the sheet laminating mechanism and the flat laminating mechanism.

[0012] The internal structure of the adhesive sheet lamination mechanism is divided by adhesive sheets to form an upper vacuum chamber and a lower vacuum chamber. The lower vacuum chamber is used to compress the components.

[0013] The flat lamination mechanism has a flat lamination chamber, and the flat lamination chamber has a liftable flat plate, which is used to press the component after it has been processed by the sheet lamination mechanism downward.

[0014] Through the above technical solution, this utility model divides the lamination process into two stages by setting up two independent lamination mechanisms (a sheet lamination mechanism and a flat plate lamination mechanism). This avoids the tedious operation of repeated lamination in traditional single-cavity lamination processes, greatly shortening the overall lamination process time and thus significantly improving production efficiency. The sheet lamination mechanism uses vacuum pressure difference to achieve initial extrusion of the module, effectively eliminating residual air bubbles inside the module and softening the adhesive film to a fluid state. The flat plate lamination mechanism performs secondary heating and pressurization after the module has undergone initial treatment, allowing the adhesive film to reach a cross-linked and cured state, further ensuring tight adhesion of the module, improving the photoelectric conversion efficiency and service life of the module, and guaranteeing the stability and consistency of product quality. The structural design of this device can better adapt to the requirements of large-scale, high-speed production lines of modern photovoltaic enterprises, meet the stable market demand for high-quality photovoltaic modules, and help enterprises enhance their market competitiveness.

[0015] Preferably, in the above-mentioned single-chamber sheet-to-two-chamber flat-plate lamination device, the sheet lamination mechanism includes a first upper fixed plate, a first frame fixed to the edge of the first upper fixed plate, and a first heating plate disposed below the first upper fixed plate. A second frame corresponding to the first frame is fixed to the edge of the first heating plate, and the sheet is connected to the bottom edge of the first frame. The first upper fixed plate and the first heating plate can move relative to each other, allowing the first frame and the second frame to close accordingly. By setting the first upper fixed plate, the first frame, the first heating plate, and the second frame, a stable support and a reliable closing mechanism are provided for the sheet lamination mechanism, ensuring that all components can cooperate closely during the lamination process. This makes the sheet lamination mechanism more stable and reliable during operation, reducing production failures and quality problems caused by structural instability. The corresponding closing design of the first and second frames helps to form a good sealing environment, ensuring that the upper and lower vacuum chambers can reach the ideal vacuum level during the vacuuming process, thereby improving the extrusion effect of the sheet on the component, further enhancing the removal of air bubbles inside the component, and ensuring the lamination quality of the component.

[0016] Preferably, in the above-described single-cavity sheet-to-two-cavity flat-plate lamination device for components, the sheet, the first frame, and the first upper fixed plate enclose the upper vacuum chamber, and the sheet, the second frame, and the first heating plate enclose the lower vacuum chamber. The sheet moves downwards due to the vacuum pressure difference between the upper and lower vacuum chambers. Utilizing the vacuum pressure difference between the upper and lower vacuum chambers to drive the sheet downwards allows for precise control of the sheet's extrusion action, ensuring uniform pressure on the component. This avoids component damage or uneven lamination caused by excessive or insufficient local pressure, improving the uniformity and consistency of component lamination. By rationally designing the structure and volume of the upper and lower vacuum chambers, the magnitude of the vacuum pressure difference can be precisely adjusted. This allows for flexible control of the sheet's extrusion speed and force according to different component characteristics and process requirements, further optimizing the lamination process and improving the lamination effect and quality of the components.

[0017] Preferably, in the above-mentioned laminating device for a single-chamber sheet-to-two-chamber flat plate assembly, a first high-temperature resistant sealing strip is embedded in the bottom edge of both the first and second frames. Embedding the first high-temperature resistant sealing strip in the bottom edges of the first and second frames effectively prevents air leakage during the vacuum process, further improving the sealing performance of the vacuum chamber and ensuring that the upper and lower vacuum chambers reach the ideal vacuum level. This ensures that the sheet can smoothly and accurately extrude the assembly under the vacuum pressure difference, improving the reliability and stability of the lamination process. The high-temperature resistant sealing strip maintains good sealing performance in high-temperature environments, avoiding problems such as aging and deformation of the sealing strip caused by high temperatures. This reduces equipment failures and maintenance frequency caused by poor sealing, extends the service life of the equipment, and lowers maintenance costs.

[0018] Preferably, in the above-mentioned single-cavity sheet-pressing and two-cavity flat-plate-pressing assembly lamination device, the flat-plate lamination mechanism includes a second upper fixed plate, a third frame fixed to the edge of the second upper fixed plate, and a second heating plate disposed below the second upper fixed plate. The second upper fixed plate and the second heating plate can generate relative movement and combine with the third frame to form the flat-plate lamination chamber. The bottom surface of the second upper fixed plate is connected to the flat plate through a telescopic component, and a component hot-pressing gap is formed between the flat plate and the second heating plate. The flat-plate lamination mechanism, through the combination of the second upper fixed plate, the third frame, and the second heating plate, forms an independent flat-plate lamination chamber. The flat plate can be raised and lowered through the telescopic component, enabling secondary precise pressurization of the assembly after preliminary processing by the sheet-plate lamination mechanism according to the characteristics and process requirements of the assembly, further ensuring the tight bonding of the assembly and improving the molding quality of the assembly. The telescopic assembly allows the lifting action of the plate to be flexibly adjusted according to different process requirements. For example, by controlling the air pressure of the telescopic assembly, the pressure between the plate and the assembly can be precisely adjusted, thereby achieving adaptive processing of assemblies of different thicknesses and materials, and improving the process flexibility and versatility of the device.

[0019] Preferably, in the above-mentioned lamination device for a single-chamber sheet-pressed and two-chamber flat-plate laminated assembly, a second high-temperature resistant sealing strip is embedded along both the upper and lower edges of the third frame. Embedding the second high-temperature resistant sealing strip along the upper and lower edges of the third frame effectively prevents gas leakage during the heating and pressurization process of the flat-plate lamination chamber, ensuring stable pressure within the chamber, thereby improving the effect and quality of the secondary pressurization and further enhancing the lamination effect of the assembly. Good sealing performance helps maintain a uniform temperature and pressure distribution within the flat-plate lamination chamber, avoiding localized temperature and pressure fluctuations caused by gas leakage, thus ensuring the stability and consistency of the secondary pressurization process, ensuring that the assembly is uniformly heated and pressurized during lamination, and improving the quality stability of the assembly.

[0020] Preferably, in the above-mentioned laminating device for a single-cavity sheet-to-two-cavity flat plate assembly, a silicone pad is fixed to the bottom surface of the flat plate. The silicone pad has good flexibility and elasticity, enabling it to evenly distribute the pressure of the flat plate on the assembly, preventing excessive local pressure caused by direct contact between the flat plate and the assembly, thus protecting the assembly surface, reducing the risk of scratches and damage, and improving the appearance quality and reliability of the assembly. The silicone pad also has certain thermal conductivity, forming a good thermal conductivity medium between the flat plate and the assembly, allowing the assembly to be heated more evenly during hot pressing, further improving the hot pressing effect and molding quality. The silicone pad is easy to clean, effectively preventing residual adhesive film or other impurities from adhering to the flat plate surface during lamination, facilitating equipment cleaning and maintenance, and maintaining the cleanliness and efficient operation of the production line.

[0021] Preferably, in the above-mentioned laminating device for a single-cavity sheet-to-two-cavity flat plate assembly, the telescopic component includes multiple telescopic cylinders. The telescopic cylinders provide stable and reliable power support for the lifting and lowering of the flat plate, ensuring smooth and accurate movement of the flat plate during secondary pressurization. This avoids problems such as unstable flat plate movement and uneven pressurization caused by insufficient or unstable power, thereby improving the lamination quality of the assembly. By controlling the air pressure of the telescopic cylinders, the pressure between the flat plate and the assembly can be precisely adjusted, enabling adaptive processing of different components and further improving the device's process flexibility and processing accuracy.

[0022] Preferably, in the above-mentioned laminating device for a single-cavity sheet-to-two-cavity flat plate assembly, the telescopic cylinder is provided with a high-temperature resistant flexible protective sleeve on its outer side. The high-temperature resistant flexible protective sleeve can effectively protect the telescopic cylinder for normal operation in high-temperature environments, preventing damage or performance degradation caused by high temperatures, extending the service life of the telescopic cylinder, and reducing equipment maintenance costs. The protective sleeve also prevents accidental collisions or friction between the telescopic cylinder and surrounding components during operation, further improving the safety and reliability of the equipment.

[0023] Preferably, in the above-mentioned lamination device for pressing a single-cavity sheet into a two-cavity flat plate into a component, the flat plate is made of lightweight metal or rigid, high-temperature resistant non-metallic material. Using lightweight metal or rigid, high-temperature resistant non-metallic materials to make the flat plate effectively reduces the overall weight of the equipment, lowers operating energy consumption, and improves operating efficiency while ensuring the plate's strength and high-temperature resistance. These materials have excellent high-temperature resistance, maintaining stable physical and chemical properties in high-temperature environments, ensuring the flat plate can withstand the high-temperature environment during lamination without deformation or damage, thereby improving the equipment's reliability and service life. Rigid, high-temperature resistant non-metallic materials, such as carbon fiber reinforced plastics, also have high wear resistance, reducing wear caused by friction during contact with the component, further improving the plate's durability and service life.

[0024] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a laminating device for a one-cavity adhesive sheet and a two-cavity flat plate assembly, which has the following beneficial effects:

[0025] 1. Significantly Improved Production Efficiency: Utilizing a dual-chamber structure with both sheet lamination and flat plate lamination mechanisms, the lamination process is divided into two stages. This staged approach avoids the tedious repeated lamination operations of traditional single-chamber lamination processes, greatly shortening the overall lamination time and significantly improving production efficiency. This device better adapts to the large-scale, high-speed production line requirements of modern photovoltaic enterprises, ensuring a stable supply of high-quality photovoltaic modules and helping companies enhance their market competitiveness.

[0026] 2. Improved Product Quality and Stability: The sheet lamination mechanism uses vacuum pressure difference to initially compress the module, effectively eliminating residual air bubbles inside the module and softening the adhesive film to a fluid state. The flat lamination mechanism then applies secondary heating and pressure after the initial processing, causing the adhesive film to cross-link and cure, further ensuring tight adhesion. This phased process optimization significantly improves the lamination effect and quality stability of the module. The dual-chamber design reduces the difficulty of controlling process parameters caused by multiple lamination operations, lowers the risk of quality fluctuations during production, ensures consistent module quality, and meets market demand for high-quality photovoltaic modules. By optimizing the lamination process, residual air bubbles and uneven adhesive film flow inside the module are reduced, improving the photoelectric conversion efficiency and lifespan of the module, further enhancing the product's market competitiveness.

[0027] 3. Reduced Equipment Maintenance Costs: High-temperature resistant sealing strips are embedded in key areas of the sheet lamination and flat plate lamination mechanisms, effectively improving the sealing performance of the vacuum and hot-pressing chambers and reducing equipment failures and maintenance frequency caused by poor sealing. The high-temperature resistant flexible protective sleeve on the outside of the telescopic cylinder effectively protects the cylinder's normal operation in high-temperature environments, extending its service life. Meanwhile, the flat plates are made of lightweight metal or hard, high-temperature resistant non-metallic materials, improving the wear resistance and durability of components and further reducing equipment maintenance costs. Through optimized structural design and material selection, downtime for equipment repair due to malfunctions is reduced, improving equipment operating efficiency and stability, and lowering the company's operating costs.

[0028] 4. Improved Process Flexibility and Adaptability: By controlling the air pressure of the telescopic cylinder and the temperature of the heating plate, the pressure and temperature between the plate and the component can be flexibly adjusted, enabling adaptive processing of components of different thicknesses and materials, thus improving the process flexibility and versatility of the device. The adhesive sheet lamination mechanism and the plate lamination mechanism independently control the pressure and temperature, allowing for flexible adjustments according to different process requirements, further optimizing the lamination process and meeting diverse production needs.

[0029] 5. Enhanced Overall Equipment Performance and Reliability: By rationally designing the structure of the sheet lamination mechanism and the flat plate lamination mechanism, the tight cooperation of each component during the lamination process is ensured, improving the overall stability and reliability of the equipment. Using lightweight metal or hard, high-temperature resistant non-metallic materials for the flat plates not only reduces the weight of the equipment but also improves the high-temperature resistance and wear resistance of the components, further enhancing the overall performance of the equipment. The silicone pad layer on the bottom of the flat plate is easy to clean and effectively prevents residual adhesive film or other impurities from adhering to the flat plate surface during the lamination process, facilitating equipment cleaning and maintenance and maintaining the cleanliness and efficient operation of the production line.

[0030] 6. Promoting the Development of the Photovoltaic Industry: By improving production efficiency, enhancing product quality, and reducing production costs, this device can better meet the stable market demand for high-quality photovoltaic modules, thus promoting the large-scale development of the photovoltaic industry. This innovative lamination device provides new technological ideas for the photovoltaic module manufacturing field, helping to further develop and upgrade photovoltaic technology and providing strong support for the sustainable development of the photovoltaic industry.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] See appendix Figure 1 To be continued Figure 5 This utility model discloses a lamination device for a one-cavity glue sheet and a two-cavity flat plate lamination assembly, including a glue sheet lamination mechanism 1 and a flat plate lamination mechanism 2 arranged in sequence, and a conveying mechanism 3 for conveying and connecting the glue sheet lamination mechanism 1 and the flat plate lamination mechanism 2.

[0046] The interior of the adhesive sheet lamination mechanism 1 is divided by adhesive sheets 11 to form an upper vacuum chamber 12 and a lower vacuum chamber 13. The lower vacuum chamber 13 is used to compress the component 4.

[0047] The flat lamination mechanism 2 has a flat lamination chamber 21, and the flat lamination chamber 21 has a liftable flat plate 22, which is used to press the component 4 after it has been processed by the sheet lamination mechanism 1 downward.

[0048] To further optimize the above technical solution, the adhesive sheet laminating mechanism 1 includes a first upper fixing plate 14, a first frame 15 fixed to the edge of the first upper fixing plate 14, and a first heating plate 16 disposed below the first upper fixing plate 14. A second frame 17 corresponding to the first frame 15 is fixed to the edge of the first heating plate 16, and an adhesive sheet 11 is connected to the bottom edge of the first frame 15. The first upper fixing plate 14 and the first heating plate 16 can generate relative movements, so that the first frame 15 and the second frame 17 can close accordingly.

[0049] To further optimize the above technical solution, the rubber plate 11, the first frame 15 and the first upper fixing plate 14 are arranged to form an upper vacuum chamber 12, and the rubber plate 11, the second frame 17 and the first heating plate 16 are arranged to form a lower vacuum chamber 13. The vacuum pressure difference formed by the upper vacuum chamber 12 and the lower vacuum chamber 13 causes the rubber plate 11 to move downward.

[0050] To further optimize the above technical solution, a first high-temperature resistant sealing strip 18 is embedded in the bottom edge of the first frame 15 and the bottom edge of the second frame 17.

[0051] To further optimize the above technical solution, the flat plate laminating mechanism 2 includes a second upper fixed plate 23, a third frame 24 fixed to the edge of the second upper fixed plate 23, and a second heating plate 25 disposed below the second upper fixed plate 23. The second upper fixed plate 23 and the second heating plate 25 can generate relative movement and combine with the third frame 24 to form a flat plate laminating chamber 21. The bottom surface of the second upper fixed plate 23 is connected to a flat plate 22 through a telescopic component 26, and a component hot pressing gap 27 is formed between the flat plate 22 and the second heating plate 25.

[0052] To further optimize the above technical solution, a second high-temperature resistant sealing strip 28 is embedded in the lower and upper edges of the third frame 24.

[0053] To further optimize the above technical solution, a silicone pad layer 29 is fixed on the bottom surface of the flat plate 22.

[0054] The silicone pad 29 can withstand high temperatures and is suitable for use in high-temperature operating environments between the second heating plate 25 and the plate 22. As a non-metallic material, the silicone pad 29 has relatively low thermal conductivity, which helps maintain the temperature control of component 4. The use of the silicone pad 29 can reduce direct friction between the plate 22 and component 4, reduce wear, and improve the durability and service life of the equipment. The silicone material is easy to clean, which helps to maintain and clean the contact surfaces of the plate 22 and component 4, keeping the production line clean and efficient.

[0055] To further optimize the above technical solution, the telescopic assembly 26 includes multiple telescopic cylinders.

[0056] To further optimize the above technical solution, a high-temperature resistant flexible protective sleeve is provided on the outside of the telescopic cylinder.

[0057] High-temperature resistant flexible protective sleeves typically refer to protective sleeves that can withstand high-temperature environments while maintaining flexibility, used to protect mechanical components such as telescopic cylinders. The material selection for these sleeves depends on factors such as the maximum temperature they need to withstand, chemical stability, abrasion resistance, and cost. Some commonly used high-temperature resistant flexible materials include:

[0058] Silicone: Silicone is a widely used high-temperature resistant material that can maintain flexibility and stability in a temperature range of -60℃ to 250℃, making it suitable for a variety of high-temperature environments.

[0059] Fluororubber: Fluororubber has excellent high temperature resistance and can be used in a temperature range of -20℃ to 250℃. It also has good chemical resistance and oil resistance.

[0060] Polytetrafluoroethylene (PTFE): PTFE is a non-sticky, high-temperature resistant plastic that can be used in a temperature range of -200℃ to 260℃, and has excellent chemical stability and a low coefficient of friction.

[0061] Polyimide (PI): Polyimide is a high-performance polymer that remains stable in a temperature range of -100℃ to 300℃ and has good mechanical properties and chemical resistance.

[0062] Glass fiber reinforced materials: such as glass fiber reinforced polyester or epoxy resin, these materials can provide additional strength and high temperature resistance.

[0063] Specialty rubbers, such as nitrile rubber (NBR) and ethylene propylene rubber (EPDM), can also withstand high temperatures to some extent, but their temperature resistance is usually not as high as that of the materials mentioned above.

[0064] Metal protective sleeves: In some cases, protective sleeves made of stainless steel or other high-temperature resistant metals may be used to provide additional protection and strength.

[0065] To further optimize the above technical solution, the plate 22 is made of lightweight metal or hard, high-temperature resistant non-metallic material.

[0066] Specifically, the flat plate 22 can be made of the following materials:

[0067] Lightweight metal material:

[0068] Aluminum alloys: Aluminum alloys are lightweight and high-strength materials with good thermal conductivity, making them suitable for applications requiring lightweight construction and heat dissipation. Commonly used aluminum alloy grades include 6061, 6063, and 7075.

[0069] Titanium alloys: Titanium alloys have high strength, low density, and good corrosion resistance, but their cost is relatively high. They are widely used in aerospace, medical devices, and other fields.

[0070] Magnesium alloys: Magnesium alloys are among the lightest metallic structural materials, possessing excellent mechanical properties and electromagnetic shielding effects, making them suitable for applications requiring extreme lightweighting.

[0071] Hard, high-temperature resistant non-metallic material:

[0075] Ceramic matrix composites: Ceramic materials themselves have extremely high high-temperature resistance, but they are also quite brittle. Composite material technology can improve their toughness, making them suitable for extreme high-temperature environments.

[0076] Aramid fibers (such as Kevlar): Aramid fibers have extremely high strength and heat resistance, and are often used in bulletproof materials and high-performance composite materials.

[0077] Glass fiber reinforced plastic (GFRP): Glass fiber reinforced plastics have good mechanical properties and high temperature resistance, and the cost is relatively low.

[0078] The component lamination apparatus provided in this embodiment includes two execution chambers formed by a sheet lamination mechanism 1 and a flat plate lamination mechanism 2. The two chambers perform the vacuum and pressurization processes in the lamination process separately.

[0079] The laminating mechanism 1 is responsible for the heating and vacuuming process in the module lamination process. Its purpose is to remove residual air bubbles inside the stacked modules, allowing the module adhesive film to soften and flow. The laminating chamber is divided into an upper vacuum chamber 12 and a lower vacuum chamber 13 (composed of the adhesive plate and the lower heating plate). When the module enters the laminating chamber, the laminator is closed, and the upper and lower vacuum chambers simultaneously begin the vacuuming process. Due to the volume difference between the upper and lower vacuum chambers, a pressure difference exists. Therefore, the adhesive plate 11 presses downwards against the module under this pressure difference until it is completely pressed against the upper surface of the module. Since the first heating plate 16 is heated, the adhesive film is in a softened and flowing state. Under the pressure of the adhesive plate 11, it squeezes out residual air bubbles inside the module, achieving a gas-free vacuum state inside the module.

[0080] The flat lamination mechanism 2 is responsible for the secondary heating and pressurization process in the lamination operation. Since the first-chamber lamination chamber has already undergone preliminary heating and vacuuming of the component, the adhesive film inside the component has softened and flowed on the first-chamber heating plate, and all internal air has been completely removed. At this point, the laminator opens, and the component enters the flat lamination chamber 21 under the drive of the conveyor mechanism 3 for the secondary flat lamination process. This process involves secondary heating of the component based on the adhesive film material characteristics, causing it to reach a cross-linked and cured state. Simultaneously, the high-temperature resistant pneumatic telescopic component 26 (or a high-strength, high-temperature resistant flexible material) drives the flat plate 22 (a lightweight metal material or a rigid, high-temperature resistant non-metal) downwards. By adjusting the air pressure of the telescopic component 26, the flat plate 22 with the silicone pad layer 29 is tightly fitted to the component, performing secondary lamination and shaping the component.

[0081] The two chambers are independently controlled for pressure and temperature, which refines the process steps, greatly shortens the overall lamination process time, improves production efficiency, and ensures the quality of module production.

[0082] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
