Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to a hot press for the production of solar glass panels. Background Technology

[0002] In the current booming development of the solar photovoltaic industry, solar glass panels, as a key component of photovoltaic modules, have a crucial impact on product quality and performance due to their manufacturing process. Currently, in the production of solar glass panels, the hot press is the core equipment for encapsulating the glass panel with components such as encapsulant film or backsheet.

[0003] A hot press for producing solar glass panels, disclosed in Chinese Patent Publication No. CN222411311U, uses a pressure plate. A hydraulic cylinder pushes a movable table upwards along a guide groove, causing the lower mold to press against the upper mold and complete the hot pressing process. However, based on existing hot presses and related technologies, most current hot presses use a single-mold structure, processing only one solar glass panel at a time. After each hot pressing, the panel must cool before it can be removed and a new panel inserted. During this cooling process, the equipment is idle and cannot perform other processing, resulting in low production efficiency. Furthermore, during the hot pressing process, operators must handle the material in a high-temperature, high-pressure environment, increasing the risk of burns and injuries. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a hot press for the production of solar glass panels.

The self-locking component is U-shaped, and two insertion holes adapted to the self-locking component are opened on the front side of the top of the two slide rails. The slider has through holes at both ends corresponding to the self-locking component.

[0010] Preferably, the adjustment mechanism includes a frame fixedly installed on the top of the machine base, a hydraulic cylinder fixedly installed on the top of the frame, the output end of the hydraulic cylinder passing through the mounting plate of the frame, a pressure plate provided on the frame below the mounting plate, the pressure plate being connected to the mounting plate through multiple elastic telescopic components, two fixing rods being symmetrically fixedly installed on the top of the mounting plate, and sliding holes being provided on the frame corresponding to the positions of the two fixing rods.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0026] like Figures 1 to 8As shown, a hot press for producing solar glass panels includes a machine base 1 and two upper molds 2 with heating functions. Two lower molds 3 are slidably mounted on the machine base 1. The machine base 1 is provided with sliding components 4 at the bottom of the two lower molds 3. The sliding components 4 include a slide rail 401 fixedly mounted on the top of the machine base 1, and a slider 402 is slidably mounted on the surface of the slide rail 401. The lower molds 3 are fixedly mounted on the top of the sliders 402. The machine base 1 is provided with a synchronization component 5 between the two sliders 402 for controlling the opposing sliding of the two sliders 402. The front side of the top of the two sliders 402 is provided with a self-locking component 6. The top of the machine base 1 is provided with an adjustment mechanism 7 for controlling the movement of the two upper molds 2.

[0027] like Figures 1 to 4 As shown, the adjustment mechanism 7 includes a frame 701 fixedly installed on the top of the machine base 1. A hydraulic cylinder 702 is fixedly installed on the top of the frame 701. The output end of the hydraulic cylinder 702 passes through the frame 701 and is mounted on a fixing plate 703. A pressure plate 704 is provided on the frame 701 below the fixing plate 703. The pressure plate 704 is connected to the fixing plate 703 through multiple elastic telescopic components 705. Two fixing rods 706 are symmetrically fixedly installed on the top of the fixing plate 703. Sliding holes are provided on the frame 701 at the positions corresponding to the two fixing rods 706. The upper molds 2 are symmetrically fixedly installed on the bottom of the pressure plate 704. The two upper molds 2 are respectively adapted to the two lower molds 3.

[0028] like Figures 3 to 7 As shown, the synchronization component 5 includes a gear 501. Multiple meshing grooves 502 are formed on the side of each of the two sliders 402 near the gear 501. A receiving groove is formed on the machine base 1 at the position of the gear 501. A rotating shaft 503 is fixedly mounted at the center of the gear 501. Rotation holes are formed at both ends of the rotating shaft 503 on the machine base 1. Both ends of the rotating shaft 503 are connected to the rotation holes via bearings. Using these bearings, the friction force during the rotation of the gear 501 can be reduced, improving the stability of the gear 501 during rotation. Furthermore, by hiding the gear 501 inside the machine base 1, impurities can be prevented from affecting the gear 501. 01 Operation; In summary, after the previous solar glass panel is processed, the two sliders 402 can be switched by pulling out the self-locking part 6. This allows one lower mold 3 to be hot-pressed under the upper mold 2 while the other lower mold 3 can simultaneously perform cooling, removal, and replacement of the solar glass panel. This reduces waiting time, enables continuous operation, and effectively improves production efficiency. At this time, the workers can safely remove the processed solar glass panel from the separated lower mold 3, avoiding the safety risks such as burns that may occur during the hot-pressing process.

[0029] like Figures 5 to 8As shown, the self-locking component 6 is a handle. The self-locking component 6 is inserted into the slider 402. The self-locking component 6 is U-shaped. Two insertion holes 4011 that are adapted to the self-locking component 6 are opened on the front side of the top of the two slide rails 401. The slider 402 has through holes 4021 at both ends corresponding to the self-locking component 6. Under the action of its own weight, the self-locking component 6 can automatically insert into the insertion holes 4011. Thus, through the cooperation between the gear 501 and the meshing groove 502, the position of the two sliders 402 is locked. This can effectively prevent the mold from shifting or shaking during the hot pressing process, ensuring the stability of the solar glass panel during hot pressing, which is conducive to improving the processing quality of the product and reducing product defects caused by mold instability.

[0030] The work process is as follows:

[0031] S1, such as Figure 1 , Figure 4 and Figure 5 As shown, when in use, a solar glass panel can be placed inside one of the lower molds 3, and then the slider 402 is slid by the self-locking part 6, so that the lower mold 3 corresponds to its matching upper mold 2.

[0032] S2, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, when the lower mold 3 corresponds to its matching upper mold 2, the gear 501 and the meshing groove 502 work together to move the lower mold 3 on top of the other slider 402 to the front of the machine 1, away from the adjustment mechanism 7. Then, the self-locking part 6 can automatically insert into the insertion hole 4011 under its own weight. Thus, the position of the two sliders 402 is locked by the gear 501 and the meshing groove 502. This can effectively prevent the mold from shifting or shaking during the hot pressing process, ensuring the stability of the solar glass panel during hot pressing, which is conducive to improving the processing quality of the product and reducing product defects caused by mold instability.

[0033] S3, such as Figures 1 to 3 As shown, the fixed plate 703, elastic telescopic component 705, pressure plate 704 and two upper molds 2 are controlled by hydraulic cylinder 702 to move downward, so that the upper mold 2 and the lower mold 3 are in contact. Then, the glass panel and components such as adhesive film or back plate are encapsulated by heating the upper mold 2.

[0034] S4. After the previous solar glass panel is processed, the two sliders 402 can be switched by pulling out the self-locking part 6. This allows one lower mold 3 to be hot-pressed under the upper mold 2 while the other lower mold 3 can simultaneously perform cooling, removal and replacement of the solar glass panel. This reduces waiting time, enables continuous operation, and effectively improves production efficiency.

[0035] S5. When one of the lower molds 3 slides to the bottom of the upper mold 2, the other lower mold 3 automatically separates from the other upper mold 2. At this time, the workers can safely remove the processed solar glass panel from the separated lower mold 3, avoiding the safety risks such as burns that may be caused by taking it out during the hot pressing process.

[0036] The upper mold 2, lower mold 3 and adjustment mechanism 7 described in this application are all known technologies in this field, therefore their specific structures and working principles are not described in detail.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
