Abstract
The present invention provides a sealing method and product of a double-glass photovoltaic module and a used device. The same glass materials of the upper and lower surface layers of the double-glass photovoltaic module are molten in high temperature equipment, then a coating device is used to uniformly smear molten glass liquid to the four end faces of the double-glass photovoltaic module, followed by natural cooling. The coating device used in the above method is a high temperature glue gun. The sealing method and product and the used device have the advantages that the sealing performance of the product is good, and the service life is long with more than 50 years.
Description
The encapsulating method of technical field: the present invention relates to the Sealing Technology in a kind of photovoltaic module, particularly a kind of pair of glass photovoltaic module and product and device used.
Background technology: in existing photovoltaic industry when sealing the surrounding of two glass assembly (namely superposing by glass-EVA adhesive film-cell piece-EVA adhesive film-glass the photovoltaic module formed successively), the method for employing the surrounding of assembly is sealed with butyl rubber belt or silica gel.The deficiency that the method in use exists is: the poor stability of sealing, the useful life of product is short, this is that the upper and lower material of two glass stack face is glass, because butyl rubber belt or silica gel all belong to different materials from glass, their build-in attribute is different, its contact-making surface is only physical bond, cannot form sealing completely reliably; After adopting in the harsh out of doors environment of assembly of the method sealing a period of time that works, the knot of bi-material touches face and is easily separated, and causes steam to enter, and then attacks components internal structure and components and parts, finally causes whole component failures.
Summary of the invention: the object of the invention is, for the poor stability of the existing pair of glass assembly sealing existing when sealing surrounding, the deficiency that useful life of product is short, and provide a kind of good stability of sealing, the encapsulating method of two glass photovoltaic modulies of long product lifecycle and product and device used.
Pass through following technical proposals, object of the present invention can be realized, the encapsulating method of a kind of pair of glass photovoltaic module, it is characterized in that, the glass material identical with two glass photovoltaic module upper and lower surface layer is melted in high-temperature service, then with coating unit, the glass metal of melting is coated in uniformly four end faces of two glass photovoltaic module, allows it naturally cool.
For the glassy layer making the glass metal of coating upper and lower with two glass photovoltaic module has better combination, when applying, heat the limit end of the upper and lower glassy layer of two glass photovoltaic modulies, the temperature of heating is at 100-400 DEG C.
The thickness being coated in two glass photovoltaic module four end face glassy layers is 0.1mm ~ 10mm;
Coating speed is 1mm/s ~ 1000mm/s.
The product that said method is made, is characterized in that, the encapsulant of two glass photovoltaic modulies four end faces is glass.
For the coating unit in said method, it is characterized in that, this device is high-temp glue rifle, and it is made up of rifle body, muzzle; Muzzle is a notch, is provided with heater in it, is provided with heating cavities, heater and vacuum valve in rifle body.
Effect of the present invention is: the good seal performance of product, long service life, this is that this method encapsulant used is the glass material identical with the upper and lower glassy layer of two glass photovoltaic modulies, thermal is added by uniform temperature between them, encapsulant can be made to form a complete entirety with by the material sealed, between form firmly chemical bond, thus assembly can be made from the existing useful life extending to more than 50 years useful life being no more than 25 years out of doors.

Embodiment:
An encapsulating method for pair glass photovoltaic module, it seals two glass photovoltaic module according to the following steps: by clean for the whole surface cleaning through the good two glass photovoltaic modulies of lamination, see accompanying drawing 1, two glass photovoltaic module is by upper and lower glass 1 material layer; The second, the 4th EVA adhesive film 2 material layer; 3rd cell piece 3 material layer composition; The draw-in groove muzzle of high-temp glue rifle is stuck in an end face of two glass photovoltaic module, vacuum valve in high-temp glue rifle is opened, the glass metal that melts in high-temp glue rifle heating cavities is applied to the end face of two glass photovoltaic module, high-temp glue rifle moves in parallel by the speed of 30mm/s (can select as the case may be between 1mm/s ~ 1000mm/s), in movement, the temperature of high-temp glue rifle draw-in groove is 300 DEG C (can select as the case may be between 100-400 DEG C), and glass metal coating layer thickness is 3mm (can select as the case may be between 0.1mm ~ 10mm); After the glass cools of surrounding coating, carry out dress terminal box; Finally this assembly cleaned, test, sorting, packaging.
The product that said method is made, see accompanying drawing 2,3, namely four end faces of two glass photovoltaic module and levels are glass 1 material, coated two layers of EVA adhesive film 2 material layer and middle cell piece 3 material layer in it.
For the coating unit in said method, see accompanying drawing 4, this device is high-temp glue rifle, is made up of rifle body 1, muzzle 2; Muzzle 2 is a notch, is provided with heater 21 in it, is provided with heating cavities 11, heater 12 and vacuum valve 13 in rifle body 1.
