Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic laminators, and particularly to a photovoltaic laminator with an automatic cleaning function. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. When producing photovoltaic panel assemblies, corresponding laminators are usually used to press EVA, solar cells, tempered glass, and backsheets into a rigid whole under high-temperature and vacuum conditions.

[0003] For example, a vacuum laminator for producing photovoltaic cell assemblies with the publication number CN113889549B includes a bottom frame and a top frame. A support block is fixedly installed inside the bottom frame. Air bags are fixedly installed on the left and right sides above the support block. First support plates are fixedly installed above and below the inner cavity of the air bag. A return spring is fixedly connected between the two first support plates. Exhaust pipes are fixedly connected to the front and rear sides of the air bag. By installing air bags on the left and right sides inside the bottom frame and the top frame, and at the same time installing exhaust pipes extending to the outside of the bottom frame on the front and rear sides of the air bag, a second support plate, a spring sleeve, a connecting spring, a sealing air baffle, and a sealing air ring are sleeved inside the exhaust pipe. When the inner cavities of the bottom frame and the top frame are evacuated during use, the gas in the inner cavities of the two air bags will be transported backward, and the kinetic energy of the air pump can be fully utilized.

[0004] Among the above-mentioned existing technologies, there are the following technical problems: When the existing photovoltaic laminator is in use, it is necessary to heat and evacuate to make the photovoltaic components fit together. However, when heating the photovoltaic components, it is not convenient to store and keep the heat. When heating the photovoltaic components subsequently, a large amount of energy is easily wasted. At the same time, after the lamination of the photovoltaic components is completed, it is not convenient to automatically clean the workbench surface. Therefore, after the lamination is completed, certain impurities adhere to the workbench surface. When the next photovoltaic component is placed on the workbench for processing, it is easy to affect the flatness of the photovoltaic component during placement, thereby reducing the subsequent lamination effect of the photovoltaic component.

[0005] Therefore, we propose a photovoltaic laminator with an automatic cleaning function to solve the problems mentioned above. Summary of the Invention

At the same time, after laminating the photovoltaic modules, it is not convenient to automatically clean the workbench surface.

The stirring rod is installed in the middle of the storage block, and one end of the stirring rod located inside the storage block is fixedly connected with a stirring impeller.

[0015] By adopting the above technical solution, the rotation of the stirring rod can make the stirring impeller rotate synchronously.

After the moving frame moves, the clamping block at the end of the guiding rod moves in the connecting groove, so that the stirring rod drives the stirring impeller to rotate, and the stirring impeller flips the sand inside the storage block, thereby improving the heat absorption and energy storage effect of the sand. Using the heat storage of the sand can maintain a certain amount of heat inside the sealing cover during the subsequent heating of the photovoltaic module, and thus reduce the energy consumption required for subsequent heating.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Example 1: Please refer to Figures 1-9, when the existing photovoltaic laminator is in use, it is necessary to make the photovoltaic components fit together by heating and evacuating. However, when heating the photovoltaic components, it is not convenient to store and keep the heat, and it is easy to cause more energy waste during the subsequent heating of the photovoltaic components. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0042] A photovoltaic laminator with an automatic cleaning function includes a support frame 1. Inside the support frame 1, a bearing platform 2 is fixedly connected. On the upper ends of the left and right sides of the bearing platform 2, heaters 3 are installed. On the side of the bearing platform 2, a first cylinder 4 is installed, and the telescopic end of the first cylinder 4 is fixedly connected with a sealing cover 5. A drainage hose 6 is installed on the sealing cover 5, and the end of the drainage hose 6 far from the sealing cover 5 is connected to an air extraction pump 7. The air extraction pump 7 is fixed on the upper end of the support frame 1. In the middle of the upper end of the sealing cover 5, a second cylinder 8 is fixedly connected, and the telescopic end of the second cylinder 8 is fixedly connected with a pressing plate 9. A flexible skirt 10 for improving the sealing performance when covering the bearing platform 2 is fixedly connected to the lower end of the sealing cover 5, and an extension skirt 11 is fixedly connected to the side of the flexible skirt 10. Heat storage and heat preservation components 12 for heat absorption and storage are installed on the front and back sides of the sealing cover 5. The heat storage and heat preservation components 12 include a storage block 121, a positioning column 122, a moving frame 123, an auxiliary spring 124, a guide rod 125, a clamping block 126, a connecting groove 127, a stirring rod 128, and a stirring impeller 129. The storage block 121 is fixed on the sealing cover 5. A positioning column 122 is arranged on the side of the storage block 121, and a moving frame 123 is installed on the positioning column 122. One end of the moving frame 123 located inside the positioning column 122 is connected to the inside of the positioning column 122 through an auxiliary spring 124. The middle of the end of the moving frame 123 extending out of the positioning column 122 is fixedly connected with a guide rod 125. A clamping block 126 is fixedly connected to the side of the end of the guide rod 125, and the clamping block 126 is inserted into the connecting groove 127 inside the stirring rod 128. The stirring rod 128 is installed in the middle of the storage block 121, and a stirring impeller 129 is fixedly connected to the end of the stirring rod 128 located inside the storage block 121. One end of the moving frame 123 located inside the positioning column 122 forms a seamless sliding connection structure with the positioning column 122 through a circumferentially fixed sealing ring, and the guide rod 125 in the middle of the moving frame 123 can move inside the stirring rod 128. The outer wall of the clamping block 126 at the end of the guide rod 125 fits with the inner wall of the connecting groove 127, and the connecting groove 127 is arranged in a spiral structure inside the stirring rod 128, and the stirring rod 128 can rotate on the storage block 121. Sand is stored inside the storage block 121.

[0043] When laminating a photovoltaic module, place the photovoltaic module in the middle of the carrier table 2. Then, start the first cylinder 4 to move the sealing cover 5 downward and cover the carrier table 2. Next, start the heater 3 and the air extraction pump 7. Heat the photovoltaic module by starting the heater 3, and evacuate the enclosed space formed between the sealing cover 5 and the carrier table 2 by using the air extraction pump 7 and the drainage hose 6. Finally, start the second cylinder 8 to move the pressing plate 9 downward, and laminate the photovoltaic module on the carrier table 2 by the downward movement of the pressing plate 9. During the process of heating by the heater 3, part of the heat is absorbed by the sand inside the storage block 121. When laminating and heating the photovoltaic module subsequently, the heat released by the sand inside the storage block 121 can ensure that there is a certain amount of heat inside the sealing cover 5, so as to reduce the energy consumption required for heating the photovoltaic module subsequently. At the same time, when evacuating the inside of the sealing cover 5 by using the air extraction pump 7 and the drainage hose 6, the moving frame 123 inside the positioning column 122 moves towards the inner side of the sealing cover 5. After the moving frame 123 moves, the guiding rod 125 and the clamping block 126 in the middle can move synchronously. After the clamping block 126 moves in the spiral connecting groove 127 inside the stirring rod 128, the stirring rod 128 can drive the stirring impeller 129 at the end to rotate synchronously. By using the rotation of the stirring impeller 129, the sand inside the storage block 121 can be stirred, so that the sand inside the storage block 121 can absorb heat and store energy evenly.

[0044] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. After laminating the photovoltaic module, it is not convenient to automatically clean the workbench surface. Therefore, after laminating, a certain amount of impurities adhere to the workbench surface. When the next photovoltaic module is placed on the workbench for processing, it is likely to affect the flatness of the photovoltaic module during placement, thereby reducing the subsequent laminating effect of the photovoltaic module. To solve this technical problem, the following technical content is disclosed in this embodiment, as Figure 2 、 Figure 4 and Figure 6 shown;

[0045] The flexible skirt 10 is connected through an air delivery hose 13 and a limiting and cleaning component 14. The limiting and cleaning component 14 clamps the photovoltaic module on the carrier table 2 when the sealing cover 5 is closed, and blows and cleans the impurities attached to the surface of the carrier table 2 after the sealing cover 5 is opened. An extrusion frame 15 is arranged above the extended skirt 11, and the upper end of the extrusion frame 15 is fixed on the support frame 1. The interiors of the flexible skirt 10 and the extended skirt 11 are interconnected, and the interiors of both the flexible skirt 10 and the extended skirt 11 are hollow structures, and both the flexible skirt 10 and the extended skirt 11 are made of elastic materials. The extended skirts 11 and the extrusion frames 15 are in one-to-one correspondence, and the extrusion frames 15 are located directly above the extended skirts 11. The limiting and cleaning component 14 includes a limiting post 141, a conduction post 142, a boosting spring 143, a clamping plate 144, a control valve 145, and an air outlet hole 146. The limiting posts 141 are fixed on the front and rear sides of the carrier table 2. The limiting posts 141 are connected to the air delivery hose 13, and a conduction post 142 is installed on the limiting post 141. The side of the conduction post 142 is connected to the carrier table 2 through a boosting spring 143. The conduction post 142 is fixed on the clamping plate 144, and a control valve 145 is installed on the conduction post 142, and air outlet holes 146 are formed in the clamping plate 144. The inner wall of the conduction post 142 is in close fit with the outer wall of the limiting post 141, and the conduction post 142 and the limiting post 141 are in sliding connection, and the interiors of the conduction post 142 and the clamping plate 144 are interconnected. The interior of the clamping plate 144 is a hollow structure, and the clamping plate 144 is symmetrically arranged about the transverse central axis of the carrier table 2, and the air outlet holes 146 on the symmetrically distributed clamping plates 144 are staggeredly distributed.

[0046] When the sealing cover 5 moves downward to cover the bearing platform 2, the flexible skirt 10 at the lower end of the sealing cover 5 is utilized, thereby improving the sealing performance when the sealing cover 5 covers the bearing platform 2. At the same time, when the sealing cover 5 moves downward, the control valve 145 on the conduction column 142 is closed. After the sealing cover 5 moves downward, the flexible skirt 10 at the lower end is squeezed by the bearing platform 2, and the air flow inside the flexible skirt 10 enters the inside of the limiting column 141 through the air conveying hose 13. After the air flow enters the limiting column 141, it can push the conduction column 142 and the clamping plate 144 to move towards the center direction of the bearing platform 2. By using the movement of the clamping plate 144, the photovoltaic module can be clamped and positioned, thus ensuring the stability of the photovoltaic module during lamination. When the lamination is completed, the sealing cover 5 is pushed upward by the first cylinder 4. After the sealing cover 5 is opened, the flexible skirt 10 gradually returns to its original position, and the clamping plate 144 and the conduction column 142 also return to their original positions under the action of the assisting spring 143. Then, the laminated photovoltaic module on the bearing platform 2 is taken out. After the photovoltaic module is taken out, the control valve 145 on the conduction column 142 is opened. At this time, the sealing cover 5 continues to move upward. After the sealing cover 5 moves upward, the extension skirt 11 connected to the flexible skirt 10 is squeezed by the squeezing frame 15, and the air flow inside the extension skirt 11 and the flexible skirt 10 enters the inside of the limiting column 141 through the air conveying hose 13. The air flow inside the limiting column 141 enters the inside of the clamping plate 144 through the conduction column 142, and the air flow inside the clamping plate 144 is ejected outward through the air outlet holes 146. The air flow ejected outward through the air outlet holes 146 can be used to automatically blow and clean the bearing platform 2.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
