Description
Technical field:
The present invention relates to the pick-up unit of used for packaging solar battery assembly fluid sealant, relate in particular to a kind of sealing property detection device of used for packaging solar battery assembly silica gel.
Background technology:
Solar module is made up of transparent glass, EVA, solar battery sheet, EVA and backboard TPT, this different materials sorts stacked successively from the top down, form the laminate of solar components then through lamination, hot setting and process for cooling, the aluminium frame is installed around it at last again, at last lead is drawn, terminal box is installed, has promptly finished the making of solar components.In solar module, silicon cell is the core of generating, and silicon cell is very fragile, must carry out the potting protection, prevents that water in air vapour, dust from corroding, and reduces photoelectric transformation efficiency.At present, after when being heating and curing by laminating machine silicon cell being packaged into laminate with glass, encapsulating material EVA and backboard, also must carry out the gluing encapsulation all around with aluminum alloy frame, guarantee that solar module uses more than 25 years, in the process that encapsulates with aluminum alloy frame, usually use silica gel to seal, the quality of silica gel quality directly has influence on the serviceable life of solar module.Therefore, solar module manufacturing enterprise should detect the sealing property of silica gel, and at present, domestic enterprise does not also have corresponding detecting method, does not more have concrete pick-up unit, also can't detect for the sealing property of silica gel.
The principal ingredient of silica gel is a silicon dioxide, is a kind of high activity sorbing material, belongs to the water insoluble and any solvent of amorphous substance, and is nonpoisonous and tasteless, and chemical property is stable, does not react with any material except that highly basic, hydrofluorite.Room temperature vulcanized silicone rubber RTV is a kind of novel elastomer silicone that comes out in the sixties, and single-component room-temperature vulcanized silicone rubber has good electrical property and chemical inertness, and its heat-resisting, anti-unaccelerated aging, flame resistant, moisture-proof, permeability are also very desirable.In-60～200 ℃ of scopes, can keep elasticity for a long time.Do not absorb heat when it solidifies, not heat release, it is little to solidify post-shrinkage ratio, good to the cohesiveness of material.The distinguishing feature of this rubber is at room temperature need not heat, pressurize and can solidify on the spot, and it is extremely convenient to use.Though single-component room-temperature vulcanized silicone rubber is easy to use, because its sulfuration is the moisture that relies in the atmosphere, so the thickness of vulcanizate is restricted, and can only be used for the occasion of needs thickness below 6 millimeters.The vulcanization reaction of single-component room-temperature vulcanized silicone rubber carries out toward the depths gradually from the surface, and glue-line is thick more, solidifies slow more.Since the anti-outdoor ageing excellent performance of this silica gel, high-low temperature resistant, cheap, become the main product that uses on the market at present.Because production technology, process conditions, the method for quality control difference of each silica gel manufacturing enterprise, the silica gel quality of being produced is also inequality, the sealing property that how to detect silica gel is the difficult problem in the industry, the applicant has designed a kind of device of special detection silica gel sealing performance, it can determine Different Silicon adhesive curing layer to the isolated effect of water in air vapour, dust, thereby judge the quality of silica gel sealing performance.
