Description

Solar Module Manufacturing Method

technical field

The invention relates to a solar module manufacturing method, in particular to an improved process of the solar module manufacturing method.

Background technique

The existing solar module is equipped with a protective diaphragm as a manufacturing process. As shown in the first figure, it adopts a vacuum process. In a vacuum chamber 1, the solar photovoltaic module 10 is placed on a heating plate 11 and heated. The temperature of the plate 11 is about 140-150°C. At this time, the upper part of the photoelectric module 10 is a lower chamber 12, and the periphery of the top surface of the lower chamber 12 protrudes slightly to locate the periphery of a diaphragm 13, forming an upper chamber above the diaphragm 13. 14. At this time, start the process of vacuuming the upper chamber 14 and the lower chamber 12. After about five minutes, release the vacuum in the upper chamber 14. Due to the pressure difference, the diaphragm 13 will be sucked down to the photoelectric module 10. The surface of the photoelectric module 10 is tightly attached to the top surface of the photoelectric module 10 due to heat, and the lower chamber 14 is still in the state of pumping air. After 12 to 15 minutes, the lower chamber 12 begins to deflate. The diaphragm 13 here The length and width are only slightly larger than the photovoltaic module 10, so the exposed top surface of the photovoltaic module 10 can be covered. Finally, the vacuum chamber 1 is opened to replace the solar photovoltaic module 10, and the excess part of the diaphragm is cut off; thus, the assembly is completed. This kind of production method requires the use of expensive vacuum equipment, which is quite costly and can only be carried out in a certain space of the vacuum chamber. When the photoelectric module is too large, it cannot work, so it needs to be ordered. In addition, the process of this method takes at least 20 minutes or more, but only a small piece of processing can be completed, which will affect the economy of future production needs. In order to provide more suitable The inventors researched and developed the actual required technology to solve the problems of high cost, low production volume, etc. that are easy to occur in the existing production.

Detailed ways

As shown in Figure 2, it is a solar module manufacturing method of the present invention, including: the first step: placing the solar module 20 on the surface of the component 21 to be assembled, and then covering it with a layer of concentrating adhesive film 22; The second step: the component 21 to be assembled is driven forward by the conveying device 2, and the solar module 20 with the concentrating adhesive film 22 is run over by the first gravity roller 23. Thermal function; the third step: the conveying device 2 drives the components 21 to be assembled forward, and rolls the solar module 20 of the concentrating film 22 with a second gravity roller 24, and the second gravity roller 24 has a pressing force The air between the concentrating adhesive film 22 and the solar module 20 is made close to a vacuum and glued together; the fourth step: the conveying device 2 drives the components 21 to be assembled forward, and uses a third gravity roller 25 Roll over the solar module 20 of the concentrating adhesive film 22, the third gravity roller 25 has surface lines, so that an increased light absorption area is formed on the concentrating adhesive film 22; the application of the present invention does not limit the components 21 to be assembled The length, as long as the transport device 2 can drive the person can be applicable. Therefore, the particularly long and wide elements 21 or solar modules 20 to be assembled can be solved after slightly adjusting the width of the conveying device 2 and each gravity roller. The above-mentioned gravity rollers are shown as a pair of rollers clamped in the figure, but it is also possible that the rollers themselves have weight, and use their own weight to carry out operations such as pressing, extrusion, and engraving, all of which have different pressing forces. The desired product can be completed in a continuous process.

The solar module 20 mentioned above refers to the solar chip connected in series to the solar cell, which can be fixed on the solar cell by an EVA (Ethylene Vinyl Acetate, ethylene vinyl acetate copolymer) or PVB (Polyvinyl Butyral, polyvinyl butyral) film. To assemble the components 21, the components 21 to be assembled are flat glass, painted steel plates or aluminum plates, or plastic plates, and then the solar chip is covered with a light-concentrating adhesive film 22 by means of EVA or PVB adhesive film. The invented process allows the three processes to produce the effect of squeezing the air, so that in addition to the protection function of the light-concentrating film with high light transmission, it also increases the function of guiding and concentrating light. In Figure 2, only the wave shape Said, but not limited to this state, so the aforementioned sandwich-type layered solar module 20 is rolled by the first, second, and third gravity rollers, so that the EVA film or PVB film is distributed It produces a more solid and near-vacuum joint with the concentrating adhesive film 22 on it or the components 21 to be assembled under it, so that the firmness between them is improved, and at the same time, the solar module 20 is fixed between the rollers. The positional relationship completely overcomes the shortcomings of the existing three-layer solar film group that it is not easy to position and fix. However, the structure of the solar energy is different from the above-mentioned ones, and it can also allow the user to squeeze out the most air at the end to complete the joint operation similar to vacuuming.

To sum up the above structure, the present invention uses the convenience and lightness of rolling, and cooperates with the mobility of the conveying equipment in the equipment to meet the needs of continuous production, saving time and effort, and the solar module 20 can be used in the same or different Continuously carry out the procedure of joining the light-concentrating adhesive film 22 on the surface of the component 21 to be assembled at intervals, so that the indirect cost of setting up vacuum equipment and the direct electricity, manpower, and material resources required for vacuuming can be saved. The cost can meet the requirements of rolling and bonding, so this case can provide good manufacturing convenience and is a completely different process from the existing ones.
