Referring to fig. 2, a method for manufacturing a photovoltaic module according to an embodiment of the present invention includes the following steps:
S101, providing photovoltaic glass, and performing injection molding on the back side of the photovoltaic glass to form a mounting seat;
and S102, arranging a fixing hole on the mounting seat, and arranging the bottom and the side wall of the fixing hole and the photovoltaic glass at intervals to form the photovoltaic module.
Referring to fig. 3, after obtaining the photovoltaic glass 1, in the embodiment of the present invention, compared with the prior art, a process of encapsulating an aluminum frame is not performed, and on the contrary, instead, the mounting base 2 is disposed on the back side of the photovoltaic glass 1 by using an injection molding technique, and the mounting base 2 is provided with the fixing hole 21, wherein the bottom and the side wall of the fixing hole 21 on the mounting base 2 are disposed at an interval with the photovoltaic glass 1, and do not penetrate through the mounting base 2 and contact the photovoltaic glass 1.
According to the manufacturing method of the photovoltaic assembly, the photovoltaic glass 1 is not packaged by using the aluminum frame, the mounting seat 2 is directly formed on the back side of the photovoltaic glass 1 in an injection molding mode, the fixing hole 21 is formed in the mounting seat 2, the problems that the production cost is high and the occupied volume is large due to the fact that the frame of the photovoltaic assembly is packaged by using an aluminum frame material are solved, and meanwhile compared with the aluminum frame photovoltaic assembly with low production efficiency due to the fact that a complex packaging process is adopted in the prior art, the manufacturing method of the photovoltaic assembly is characterized in that the mounting seat 2 is arranged by using the injection molding technology and the technical characteristic of rapid molding, and therefore the production efficiency of the photovoltaic assembly is improved.
the injection-molded mounting seat 2 may be formed in a continuous "□" shape on the back side of the photovoltaic glass 1, or the mounting seat 2 may be set at a position close to the edge of the back side of the photovoltaic glass 1 at a predetermined distance, so that the mounting seat 2 is formed in a discontinuous "□" shape on the back side. In addition, the shape of the fixing hole 21 may be a geometric shape such as "o" shape, or "Δ" shape or "□" shape, and further, a screw thread may be disposed in the fixing hole 21, or a fixing structure such as a slot or a magnet may be disposed therein, and the fixing hole 21 may also be a combination of the above geometric shapes, or a combination of the above fixing structures, or even a combination of the above geometric shapes and the above fixing structures, to utilize the structural characteristics of the shape to provide the corresponding fixing action, which is not limited in any way in the embodiments of the present invention.
In the production and manufacturing of the photovoltaic module, the temperature of the photovoltaic glass 1 is usually maintained at normal temperature, and when the photovoltaic glass 1 is subjected to injection molding of the mounting seat 2 in the embodiment of the present invention, due to the physical characteristic that the heat transfer of the glass is fast, when the molten plastic contacts the photovoltaic glass 1 which is in the normal temperature state and the heat transfer is fast, the molten plastic may cause the contact surface of the molten plastic and the photovoltaic glass 1 to be lifted and hardened, and the structural shape of the mounting seat 2 after molding is damaged, for example, the molten plastic is not fully filled in an injection mold and is hardened in advance, so that an air gap exists between the mounting seat 2 and the photovoltaic glass 1 cannot be attached to the photovoltaic glass 1, the connection strength between the mounting seat 2 and the photovoltaic glass 1 is weakened, and the mounting seat 2 is.
In order to increase the connection strength of the mounting seat 2 and the photovoltaic glass 1, in one embodiment, the photovoltaic glass 1 is subjected to a preheating treatment before the photovoltaic glass 1 is subjected to injection molding of the mounting seat 2, so as to prevent premature hardening of the plastic in a molten state. The preheating mode of the photovoltaic glass 1 may be exposure to the sun for preheating, or may be preheating in a heating device, and the embodiment of the present invention is not particularly limited.
the temperature resistance limit of the crystalline silicon cell string 13 in the photovoltaic glass 1 is below 200 ℃, the temperature of a feeding part in an injection molding machine is generally between 30 ℃ and 70 ℃, the temperature in a charging barrel is between 75 ℃ and 85 ℃, the nozzle temperature of the injection molding machine can reach 100 ℃, in order to reduce the temperature difference between the photovoltaic glass 1 and the plastic in a molten state in the injection molding machine and reduce the cooling and hardening speed of the plastic, in one embodiment, the temperature for preheating the photovoltaic glass 1 is between 30 ℃ and 100 ℃, and the photovoltaic glass 1 and the molten plastic are preheated on the premise of not damaging the photovoltaic glass 1 and the molten plastic.
after the photovoltaic glass 1 is subjected to preheating treatment, the photovoltaic module is in a high-temperature state, and the mounting seat 2 formed by injection molding is also in a high-temperature state, so that the cooling forming speed of the mounting seat 2 is increased, and the situation that a producer is scalded when carrying the photovoltaic module which is just formed is also prevented, in another embodiment, the photovoltaic glass 1 is subjected to cooling treatment after the mounting seat 2 is subjected to injection molding, wherein the cooling treatment comprises cooling by adopting cold air at 15-20 ℃.
In order to avoid short-circuit accidents caused by the adhesion of condensed water to the formed photovoltaic module, in another embodiment, the photovoltaic module is formed and cooled and then subjected to dehumidification treatment. The dehumidification treatment may be to introduce normal temperature dry air again, or to add a desiccant, and the embodiment of the present invention is not particularly limited.
Generally, injection molded mounting base 2 may be made of a variety of plastic materials, however, in order to ensure that the molded mounting base 2 has stronger temperature resistance and stronger structural strength, in one embodiment, mounting base 2 is injection molded from thermosetting plastic. Since the thermosetting plastic can soften and flow when heated for the first time, and is heated to a certain temperature to generate a cross-linking reaction to solidify and harden, the change is irreversible, and then the thermosetting plastic cannot soften and flow again when heated again, and the thermosetting plastic can be solidified into a product with a determined shape and size by virtue of the characteristic of molding processing, so that the mounting seat 2 made of the thermosetting plastic in the embodiment of the invention has larger temperature resistance and structural strength compared with the mounting seat made of the thermoplastic plastic.
when the photovoltaic module with the mounting base 2 injection-molded on the back side is used, the photovoltaic module is not only subjected to the action of gravity but also subjected to external forces such as strong wind and impact in practical application, and the strength for resisting the external forces is weak only by the mounting base 2 injection-molded on the back side of the photovoltaic glass 1, so that in an example, referring to fig. 5, the mounting base 2 can be respectively extended to the edge and the light receiving surface of the photovoltaic glass 1 after injection molding, so that the mounting base 2 wraps the back side, the edge and the light receiving surface of the photovoltaic glass 1 to provide structural protection in more directions.
In addition, the fixing hole 21 on the mounting seat 2 may be arranged at the position of the back side of the photovoltaic glass 1 or at the position of the edge, but in order to maximize the light receiving area of the photovoltaic module to achieve the maximum power generation efficiency, the fixing hole 21 is not generally arranged at the position of the light receiving surface of the photovoltaic glass 1, therefore, in one embodiment, the width of the mounting seat 2 on the back side of the photovoltaic glass 1 is larger than the extending width of the mounting seat 2 on the light receiving surface, so that the area of the light receiving surface of the photovoltaic glass 1 occupied by the mounting seat 2 can be reduced while the light receiving surface of the photovoltaic glass 1 is protected by the mounting seat 2.
As a preferred embodiment, the fixing hole 21 provided on the mounting base 2 may be a threaded hole, and according to the weight of the photovoltaic module and the bearing strength of the photovoltaic module bracket, a screw with a specification of M6 × 12 or more may be selected. In order that the screws do not penetrate the mounting base 2 and do not contact the photovoltaic glass 1 after mounting, in one embodiment, the thickness of the mounting base 2 injection-molded on the back side of the photovoltaic glass 1 is 2cm to 3 cm. Through setting up certain thickness's mount pad 2 in this embodiment, can leave sufficient space at the dorsal part of photovoltaic glass 1 or border and set up fixed orifices 21, avoid the screw to have the risk of running through mount pad 2 or contact photovoltaic glass 1 after the installation.
In the installation process of the photovoltaic module, the collision between the photovoltaic modules can be avoided, in order to reduce the damage caused by direct collision between the photovoltaic modules, in one embodiment, after the installation seat 2 is molded by injection on the photovoltaic glass 1, the buffer adhesive tape 3 is pasted on the edge of the photovoltaic glass 1, so that the buffer adhesive tape 3 can absorb collision energy when the photovoltaic modules directly collide, and the damage can be avoided by reducing the external force applied to the photovoltaic glass 1 in the photovoltaic module.
in the production of photovoltaic modules, the glass surface of the tempered glass 11 in the photovoltaic glass 1 is generally as smooth as possible in order to improve the light transmittance as much as possible. However, the smooth glass surface is not favorable for the connection between the mounting seat 2 and the photovoltaic glass 1 during injection molding, and in order to increase the connection strength between the mounting seat 2 injection molded on the photovoltaic glass 1 and the photovoltaic glass 1, in one embodiment, the invention further provides a manufacturing step of the photovoltaic glass 1, which comprises the following steps:
and providing glass, performing frosting treatment on the position of the mounting seat 2, performing toughening treatment on the glass to form toughened glass 11, and laminating the toughened glass 11, EVA 12 and the crystalline silicon wafer battery string 13 to form the photovoltaic glass 1.
Because the toughened glass 11 is not allowed to be subjected to secondary processing such as hole opening, cutting, grinding and the like due to the characteristics, in the embodiment of the invention, before the toughening treatment is carried out on the glass, the position of the glass, which needs to be subjected to injection molding of the mounting seat 2, is subjected to frosting treatment, and then the toughening treatment is carried out, so that the rough surface needed on the glass when the mounting seat 2 is subjected to injection molding is ensured, and the risk that the toughened glass 11 is damaged by processing the toughened glass 11 is also avoided.
To further illustrate the method for manufacturing a photovoltaic module provided by the present invention, as shown in fig. 4, fig. 4 is a flowchart of a method for manufacturing a photovoltaic module according to another embodiment of the present invention, and the structural composition of the photovoltaic module refers to fig. 5, and the following steps of the method for manufacturing a photovoltaic module are illustrated by fig. 4 according to the embodiment of the present invention:
S201, providing glass, performing frosting treatment on the position, needing to be injection-molded, of the glass, then performing toughening treatment on the glass to form toughened glass 11, and laminating the toughened glass 11, EVA 12 and a crystalline silicon wafer battery string 13 to form photovoltaic glass 1;
S202, carrying out preheating treatment on the photovoltaic glass 1, wherein the temperature of the preheating treatment is 30-100 ℃;
