Abstract
The invention discloses a method for cleaning foreign matters on tetrafluorocloth of a photovoltaic laminating machine in the operation process, which comprises the following steps: placing a film material on a feeding end of a photovoltaic laminating machine, so that the film material is sent to a laminating platform; starting a photovoltaic laminating machine, and laminating adhesive film materials through a heating plate wrapping tetrafluoro cloth; cooling the adhesive film material to a preset temperature, and stripping the adhesive film material; wherein, the adhesive force between the adhesive film material and the foreign matter is larger than the adhesive force of the foreign matter on the tetrafluorocloth. The invention solves the problem that the yield of the photovoltaic module is affected by the existing mode of cleaning the foreign matters on the tetrafluorocloth.
Description
Technical Field
The invention relates to the technical field of cleaning of photovoltaic production equipment, in particular to a method for cleaning foreign matters on tetrafluorocloth of a photovoltaic laminating machine in the operation process.
Background
A photovoltaic laminator is an important device for manufacturing photovoltaic modules. In the lamination process, directly contacting the glass or backsheet of the photovoltaic module is the high Wen Si fluorine cloth outside the silicone sheet of the laminator. Foreign matter can adhere to the tetrafluorocloth after the conventional photovoltaic laminating machine is operated for a long time. The foreign matters are formed by melting and overflowing the packaging adhesive film of the photovoltaic module at high temperature and high pressure in the lamination process. Such foreign matter adheres to the surface of the tetrafluorocloth and, after accumulating to a certain size over time, affects the flatness of the surface of the assembly produced by subsequent lamination. The large-particle foreign matters can also break the glass of the photovoltaic module or form pits on the backboard of the photovoltaic module, so that the yield of the photovoltaic module is reduced, and the service life of the tetrafluorocloth is also reduced.
When the foreign matter on the tetrafluoro cloth is cleaned at present, the tetrafluoro cloth is disassembled after the operation of the photovoltaic laminating machine is stopped, and then the tetrafluoro cloth is cleaned in a physical or chemical treatment mode.
However, due to the need to stop the operation of the photovoltaic laminating machine and the need to disassemble the tetrafluorocloth, the existing method for cleaning the foreign matters on the tetrafluorocloth seriously affects the lamination process of the photovoltaic module, resulting in the problem of reducing the yield of the photovoltaic module.
Disclosure of Invention
In view of the deficiencies of the prior art, the present invention provides a method for cleaning foreign matter from a tetrafluorocloth of a photovoltaic laminator during operation, the method comprising:
placing a film material on a feeding end of a photovoltaic laminating machine, and conveying the film material to a laminating platform;
starting the photovoltaic laminating machine, and laminating the adhesive film material;
cooling the adhesive film material to a preset temperature, and stripping the adhesive film material;
the adhesive force between the adhesive film material and the foreign matter is larger than the adhesive force of the foreign matter on the tetrafluoro cloth.
Preferably, the preset temperature is less than or equal to 40 ℃.
Preferably, the adhesive film material is one of leftover materials, waste materials and surplus materials.
Preferably, the adhesive film material and the foreign matter comprise EVA and/or POE.
Compared with the prior art, the invention has the advantages that the waste or residual adhesive film which does not meet the production use is directly put into the photovoltaic laminating machine which normally operates, and the adhesive film can be bonded with the foreign matters attached to the tetrafluorocloth under the lamination of the heating plate which wraps the tetrafluorocloth. Because the main components of the adhesive film and the foreign matters are the same, the adhesion force between the adhesive film and the foreign matters is larger than the adhesion force of the foreign matters on the tetrafluorocloth, so that the foreign matters are separated from the tetrafluorocloth along with the adhesive film in the subsequent cooling and stripping process of the adhesive film. The operation of the photovoltaic laminating machine is not required to be stopped in the process, so that compared with the traditional tetrafluorocloth cleaning method, the influence on the laminating process of the photovoltaic module is small, and the problem of reducing the yield of the photovoltaic module is avoided.

Fig. 1 is a flow chart of a method of cleaning foreign matter on a tetrafluorocloth of a photovoltaic laminator during operation in accordance with an embodiment of the invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described in accordance with the drawings are merely exemplary and the invention is not limited to these embodiments.
It should be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and/or processing steps closely related to the solution according to the present invention are shown in the drawings, while other details not greatly related to the present invention are omitted.
In view of the shortcomings in the prior art, the present embodiment provides the following specific embodiments.
The embodiment provides a method for cleaning foreign matters on a tetrafluorocloth of a photovoltaic laminator in the operation process, as shown in fig. 1, the method includes:
and S1, placing a film material on a feeding end of a photovoltaic laminating machine, and conveying the film material to a laminating platform.
And S2, starting the photovoltaic laminating machine, and laminating the adhesive film material through a heating plate wrapping the tetrafluoro cloth. Wherein the laminated adhesive film material is at least attached to the foreign matter on the tetrafluorocloth.
And S3, cooling the adhesive film material to a preset temperature, and stripping the adhesive film material.
The adhesive force between the adhesive film material and the foreign matter is larger than the adhesive force of the foreign matter on the tetrafluoro cloth.
Specifically, the preset temperature in this embodiment is less than or equal to 40 ℃.
Preferably, in order to reuse resources, the adhesive film material in this embodiment is one of leftover materials, waste materials and surplus materials.
Preferably, in order to improve the adhesion between the adhesive film material and the foreign matter, the adhesive film material and the foreign matter comprise EVA and/or POE as constituent components. Wherein the EVA is mainly composed of ethylene-vinyl acetate copolymer, and is added with cross-linking agent, thickener, antioxidant, light stabilizer, etc. The main component of POE is polyolefin elastomer.
In this embodiment, the waste or surplus adhesive film which does not satisfy the production is directly placed in the normal operation photovoltaic laminating machine, and the adhesive film is bonded with the foreign matters attached to the tetrafluorocloth under the lamination of the heating plate which wraps the tetrafluorocloth. Because the main components of the adhesive film and the foreign matters are the same, the adhesion force between the adhesive film and the foreign matters is larger than the adhesion force of the foreign matters on the tetrafluorocloth, so that the foreign matters are separated from the tetrafluorocloth along with the adhesive film in the subsequent cooling and stripping process of the adhesive film.
The operation of the photovoltaic laminating machine is not required to be stopped in the process, so that compared with the traditional tetrafluorocloth cleaning method, the method has less influence on the laminating process of the photovoltaic module, and the problem of reducing the yield of the photovoltaic module is not caused.
In this embodiment, the laying area of the adhesive film material may be adjusted according to the distribution of the foreign matters on the tetrafluorocloth, that is, the laminated adhesive film material may be attached to the entire tetrafluorocloth or only to the foreign matter area on the tetrafluorocloth.
In the embodiment, the waste or residual adhesive film which does not meet the production use is reused, so that the cleaning of the tetrafluorocloth can be realized without using other tools or carrying out technical transformation on a laminating machine, the surface flatness of a laminated production assembly is ensured, and the service life of the tetrafluorocloth and the product yield are improved.
