Abstract
The utility model relates to a kind of solar module, comprise photovoltaic glass, the first EVA adhesive film, cell piece string, the second EVA adhesive film and backboard from bottom to top successively, the wherein one side of described first EVA adhesive film is provided with longitudinal fluting group, and each groove in described longitudinal fluting group is parallel to each other.The utility model arranges groove group on the longitudinal direction of the wherein one side of EVA adhesive film, and each groove in longitudinal fluting group is parallel to each other; When the cropped one-tenth arbitrary dimension of EVA adhesive film, can distinguish the glued membrane of difference in functionality; And the control reference of position can be provided when cell piece is stacked, several cell pieces be alignd rapidly, accurately, can not be shifted; Not only increase the qualification rate of product, production efficiency have also been obtained raising.
Description
Technical field
The utility model relates to photovoltaic field, is specifically related to a kind of solar module.
Background technology
EVA adhesive film used for packaging solar battery assembly is with EVA(ethylene-vinyl acetate copolymer) be primary raw material; through heating extrusion molding after adding various function additive according to different formulations; be applied to a kind of heat-sealable material of solar module encapsulation; cell piece group is encapsulated by it; together with upper strata photovoltaic glass, lower floor's backboard; utilize vacuum lamination technology to be glued together, play structural support, insulation, heat transfer, to effects such as the physical protections of adverse environment.
When producing solar module, need EVA adhesive film, photovoltaic glass, backboard, cell piece string to lay according to certain level, then carry out lamination, paver is from top to bottom: photovoltaic glass, EVA, cell piece string, EVA, backboard.Cell piece string needs equidistantly to put, and the both sides of cell piece need parallel with the both sides of photovoltaic glass.Rely on the experience of staff in prior art during placing battery plate often, the both sides of cell piece and the uneven situation in both sides of photovoltaic glass can occur unavoidably, and be easily shifted; Cause outward appearance defective, and affect operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of solar module, is provided with longitudinal fluting group, can makes cell piece quick alignment when stacked, improve conforming product rate in the wherein one side of EVA adhesive film.
Concrete technical scheme of the present utility model is as follows:
A kind of solar module, comprise photovoltaic glass, the first EVA adhesive film, cell piece string, the second EVA adhesive film and backboard from bottom to top successively, it is characterized in that the wherein one side of described first EVA adhesive film is provided with longitudinal fluting group, each groove in described longitudinal fluting group is parallel to each other.
Because the width of cell piece in cell piece string is between 100mm ~ 160mm, for ease of putting cell piece alignment; Preferably the spacing of adjacent two grooves is 80mm ~ 200mm.
Each groove in described longitudinal fluting group is strip groove, and the width of strip groove is 2mm ~ 5mm.
Each groove in described longitudinal fluting group is cabinet-type groove.Adopt cabinet-type groove to have two benefits: one be make glued membrane two sides can with glass contact, can not cause putting cell piece because of projection, not need point positive and negative, do not affect the operating efficiency of laying; Two is to keep film volume smooth in the production process of glued membrane, and thickness is easy to control.
Described cabinet-type groove is made up of spaced circular groove, and the diameter of circular groove is 2mm ~ 5mm.
Described cabinet-type groove is made up of spaced strip groove, and the width of strip groove is 2mm ~ 5mm.
Effect of the present utility model is: on the longitudinal direction of the wherein one side of EVA adhesive film, arrange groove group, each groove in longitudinal fluting group is parallel to each other; When the cropped one-tenth arbitrary dimension of EVA adhesive film, can distinguish the glued membrane of difference in functionality; And the control reference of position can be provided when cell piece is stacked, several cell pieces be alignd rapidly, accurately, can not be shifted; Not only increase the qualification rate of product, production efficiency have also been obtained raising.
Along with the lifting that assembly producer requires assembly generating efficiency, the collocation of the EVA adhesive film of two types is used in the market, wherein a kind of EVA adhesive film contacts with photovoltaic glass, more UV light permeability can be made, cell piece is made to absorb more luminous energy, generally be called high EVA adhesive film thoroughly, this just needs to identify in a class of making in appearance of the saturating EVA adhesive film of height, makes itself and common EVA adhesive film have differentiation.The groove group that arranges on the longitudinal direction of the wherein one side of EVA adhesive film described in the utility model also may be used for distinguishing high EVA adhesive film and common EVA adhesive film thoroughly.
Accompanying drawing explanation
Fig. 1 is the structural representation of solar module described in the utility model;
Fig. 2 is the EVA adhesive film being provided with groove group described in the utility model.
Embodiment
The utility model is further illustrated below in conjunction with accompanying drawing.
See Fig. 1 and Fig. 2, a kind of solar module, comprise photovoltaic glass 1, first EVA adhesive film 2, cell piece string 3, second EVA adhesive film 4 and backboard 5 from bottom to top successively, the wherein one side of described first EVA adhesive film 2 is provided with longitudinal fluting group, and each groove in described longitudinal fluting group is parallel to each other.The spacing of adjacent two grooves is 80mm ~ 200mm.
Each groove in longitudinal fluting group can be strip groove 6, and the width of strip groove 6 is 2mm ~ 5mm.Also can be cabinet-type groove to each groove in groove group.Cabinet-type groove can be made up of spaced circular groove 7, and the diameter of circular groove is 2mm ~ 5mm; Also can be made up of spaced strip groove 8, the width of strip groove is 2mm ~ 5mm.
Longitudinal fluting group described in the utility model can adopt the form of embossing to process.
