Description
Technical field
The present invention relates to a kind of measurement apparatus, be specifically related to a kind of EVA adhesive film advance length-measuring appliance.
Background technology
If solaode is directly exposed in air, its photoelectric transformation efficiency can quickly decline, and loses practical value.Therefore, the research and development of the encapsulation material of solaode are the most particularly significant.For reaching the purpose being isolated from the outside; use transparent, light aging resisting, adhesive property are good, Atmosphere changes can be born and have resilient ethylene-vinyl acetate copolymer (EVA) glued membrane by solar battery sheet encapsulate; and be bonded together with levels protection material, constitute solar module.
EVA is a kind of typical random macromolecular compound, in its molecular structure, substituent group irregular arrangement on strand, in strand, the configuration of asymmetric carbon atom also differs simultaneously, arrange the most irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability, additionally it has good wellability when adding heat fusing, there is during cooling and solidifying good flexibility, anti-stress cracking and adhesive property, be a kind of ideal material that can be used for solar cell package.
EVA film forming uses extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and retractable volume equipment, complete batch mixing, feeding, extrude, roll, trimming, winding process.Determine have of end product quality: raw material and formula, hot-melt extrusion process, and casting molding processes control several aspects, and during casting molding processes, environment temperature and humidity is also an important step, suitable humidity and stable temperature, the Shen of drawing that can reduce film deforms, and controls the tension force of film.
At present, the streamline that glued membrane produces needs to measure the length of glued membrane, but traditional linear measure longimetry mode is to obtain by measuring the revolution of rotary transfer axle below glued membrane, the data that this mode obtains are relatively big so the most accurate due to the error of mechanical part.
Summary of the invention
The technical problem to be solved in the present invention is: proposes one and can accurately measure EVA finished product glued membrane receipts circle measurement of length device.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of EVA adhesive film advance length-measuring appliance, it is located at above glued membrane and by spaced first ccd video camera of described glued membrane direction of advance and the second ccd video camera including hanging side by side, also include being located at the transmission axle below described glued membrane and main control computer, the speed that described transmission axle surface rotates is equal with the speed that described glued membrane advances, being provided with tachometer generator in described rotating shaft, the signal output part of described tachometer generator is connected to the signal input part of described main control computer.
Further, described first ccd video camera and the second ccd video camera are identical two.
Further, the measuring method of EVA adhesive film advance length-measuring appliance, including following characteristics step:
1) distance, between described first, second ccd video camera is h, and the piece image A of glued membrane described A is transferred to main control computer below the first ccd video camera shooting when t1, the scattergram picture of A is a；
2) surface perimeter of described transmission axle is m, and described main control computer accepts revolution information r of the described transmission axle of described tachometer generator detection from t1, as r × m=h, controls the second ccd video camera shooting glued membrane image B, and is transferred to main control computer；
3) described main control computer finds a in B, and the distance between the central point b of a and B is designated as d, when described a relative to b in glued membrane direction of advance phase the same side time, d be on the occasion of, when a relative to b in glued membrane direction of advance opposite side time, d is negative value；
4) length=h+d of the actual advance of glued membrane is calculated
The invention has the beneficial effects as follows:
Device in the present invention adds twin camera shooting photo auxiliary computed range on the basis of tradition only calculates glued membrane with the rotary distance of transmission axle.Glued membrane forward travel distance on a production line can be more precisely calculated.
