Abstract
The utility model relates to the photovoltaic assembly technical field, especially to an EVA adhesive film for manufacturing a photovoltaic assembly. The EVA adhesive film possesses positioning lines parallel with the long side of the adhesive film and arranged at equal intervals; the interval between adjacent positioning lines matches the width of a battery piece of a photovoltaic assembly to be manufactured; two adjacent positioning lines form a positioning line set; the number of the sets of positioning lines is consistent with the number of assembly battery piece strings. The EVA adhesive film for manufacturing a photovoltaic assembly possesses the positioning lines so that the battery piece strings can be parallelly arranged on the EVA adhesive film in order and at equal intervals and meanwhile can prevent offset. The EVA adhesive film for manufacturing a photovoltaic assembly guarantees the appearance quality of an assembly product, and avoids battery piece splintering possibly caused by previous tedious secondary position proofreading by people, thereby raising work efficiency and guaranteeing product quality.
Description
Technical field
The utility model relates to photovoltaic module technical field, relates in particular to a kind of EVA glue film for photovoltaic component of making.
Background technology
The energy and environment are the two large problems of world today's extensive concern.Solar energy becomes the focus of people's R and D naturally as a kind of reproducible green energy resource.Many countries have started the upsurge that develops solar energy in the world at present.Therefore, solar battery technology has obtained development fast.
Solar components makes again photovoltaic module development walk earthward from space, move towards the integrated and compact applications of building from concentrating power station, the not too large variation of its packaged type, the current market share that becomes of EVA exceedes 90% encapsulating material, and the material such as PVB, POE, conducting resinl continuing to bring out all cannot substitute the market position of EVA in a short time.
EVA is because it is by ethylene vinyl acetate copolymerization particle, add tackifier, antioxidant, anti-ultraviolet ageing agent and the calendering of other additive uniform stirrings or the curtain coating of special ratios to form, later stage cuts and embossing making herbs into wool, ensures that EVA possesses good thickness homogeneity, frictional force and tensile property.Current EVA embossing mainly contains two kinds of single-side embossing and double-sided embossings, and embossing also has lozenge, rectangle line, circular line etc. except frosted line.
The test that EVA glued membrane is low with its packaging cost, package quality is relatively stable, ageing-resistant effect can stand outdoor environment year in year out and very popular, but because its shrinkage ratio differs, under high temperature fused state, find time to cause mobile, and cause the position of a large amount of packed cell pieces that skew or local starved occur.How in the situation that not changing existing equipment, to solve the above-mentioned technical problem that adopts EVA glued membrane to bring, be the technical problem that this area will solve.
Utility model content
The technical problems to be solved in the utility model is: in order to prevent that cell piece from skew occurring before encapsulation and cause cell piece string distribution unequal-interval, artificially adjust the cell piece sliver that position causes, the utility model provides a kind of EVA glue film for photovoltaic component of making.
The utility model solves the technical scheme that its technical problem adopts: a kind of EVA glue film for photovoltaic component of making, on described EVA glued membrane, there is the equal location lines in interval that is parallel to the long limit of glued membrane, the cell piece width of the interval between described adjacent positioned lines and photovoltaic module to be produced matches, adjacent two location lines form a location lines group, and the quantity of location lines group is consistent with the quantity of assembly cell piece string.
Further, particularly, as a kind of execution mode, described location lines is protruding strip, and its length L 1 is consistent with the length L 2 of EVA glued membrane.
As another kind of execution mode, in order to save material, location lines is protruding bulk, and is symmetrically distributed in the both sides of EVA glued membrane.
The beneficial effects of the utility model are, making EVA glue film for photovoltaic component of the present utility model, because it has location lines, plays mark action, cell piece string can be neatly, be parallel to each other and the equally spaced EVA of being arranged in glued membrane on, prevent skew simultaneously.Both ensure the presentation quality of subassembly product, loaded down with trivial detailsly before having avoided again artificially again proofreaded the cell piece sliver phenomenon that position may cause, increased work efficiency, ensured product quality.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, 2, embodiment mono-of the present utility model, be applicable to the arrangement of cell piece, have the location lines 1-1 of the equal protruding strip in interval on EVA glued membrane 1, the cell piece width of the interval between described adjacent positioned lines 1-1 and photovoltaic module to be produced matches.The location length L 1 of lines and the length L 2 of EVA glued membrane 1 are consistent.When use, cell piece string can be arranged in the interval between adjacent positioned lines 1-1, prevent that the position of cell piece is offset.
As shown in Figure 3,4, embodiment bis-of the present utility model, be applicable to the arrangement of battery strings, on EVA glued membrane 1, there is the location lines 1-1 of the equal projection bulk in interval, described bulk location lines 1-1 is symmetrically distributed in the both sides of EVA glued membrane 1, and the width of the battery strings of the interval in every limit between adjacent block location lines 1-1 and photovoltaic module to be produced matches.When use, battery strings is neatly discharged by the location determined straight line of lines 1-1 of every pair of symmetrical projection bulk, has avoided battery strings to occur tiltedly to move.
The shape of location lines is not limited to above-described embodiment, can be also that other shape plays identical mark action.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
