Abstract
The utility model discloses a novel glued membrane is used in photovoltaic module encapsulation, glued membrane one side or two sides have the strip arch, and the protruding parallel arrangement of strip on strip bellied basis, has increased graininess arch or the recess of evenly distributed between the strip arch. Graininess arch or recess are rectangular pyramid form, six prisms or globular. The utility model discloses introduce graininess arch or recess between the strip arch, can effectual control batteries piece with the interval of battery piece, avoid component layer to press in -process battery piece fragmentation or battery piece interval undersize scheduling problem, graininess arch or recess can further increase the roughness on glued membrane surface, prevent the slip of battery piece at the lamination in -process.
Description
Technical field
The utility model relates to a kind of novel photovoltaic module encapsulation glued membrane.
Background technology
Photovoltaic component encapsulating glued membrane is the pith of solar photovoltaic assembly, and it is at glass and cell piece or between cell piece and backboard, can play the effect of sealing, insulation and protection to cell piece.The encapsulation of assembly generally can through heating in vacuum, after gradually pressurization carry out the process that encapsulates.Semi-molten or melting glued membrane can cause mutually sliding between cell piece string in vacuum or the melt flows that adds pressure, and cell piece and cell piece spacing cannot accurately be controlled, the defective phenomenon such as cause assembly cell piece fragmentation or string spacing is too small.The pattern structure mainly groove structure on current packaging adhesive film surface, if patent publication No. is CN2686096Y and protruding structure, as patent CN202549870U, solve glued membrane between layers rolling time the problem that easily bonds.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of novel photovoltaic module encapsulation glued membrane, effectively can control the spacing of cell piece and cell piece, to avoid in component lamination process cell piece fragmentation or the problem such as cell piece spacing is too small.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel photovoltaic module encapsulation glued membrane, the one or both sides of described glued membrane have strip projected parts, strip projected parts is arranged in parallel, has equally distributed graininess projection or groove between adjacent strip projected parts.
Further, between described adjacent strip projected parts, spacing size is equal with cell piece width.
Further, the surface of described strip projected parts is matsurface.
Further, the cross section of described strip projected parts is rectangle, triangle, semicircle or trapezoidal.
Further, graininess projection is tetrapyamid shape, hemispherical or hexa-prism.
Further, graininess groove is tetrapyamid shape, hemispherical or hexa-prism.
Further, described glued membrane is EVA adhesive film or polyolefin adhesive film.
The beneficial effects of the utility model are: strip projected parts of the present utility model design, effectively can control the spacing of cell piece and cell piece, the problem such as to avoid in component lamination process cell piece fragmentation or cell piece spacing is too small.Graininess projection between strip projected parts and groove, can make the roughness of film surface increase further, more effectively can stop the slip of cell piece.

In figure, glued membrane 1, strip projected parts 2, graininess projection 3, groove 4.
Embodiment
As shown in Figure 1, a kind of novel photovoltaic module encapsulation glued membrane, the one or both sides of described glued membrane 1 have strip projected parts 2 arranged in parallel, have equally distributed graininess protruding 3 or groove 4 between adjacent strip projected parts 2.Can also have equally distributed graininess projection 3 (Fig. 1-4) or groove 4 (Fig. 5) between described strip projected parts 2, described graininess protruding 3 or groove 4 are distributed in the one or both sides of glued membrane.Graininess projection 3 can be tetrapyamid shape as shown in Figure 1, hemispherical, hexa-prism as shown in Figure 3 as shown in Figure 2, and in like manner, groove 4 can be also multiple different shape, is hexa-prism in Fig. 5.The combination of strip projected parts 2 and particle protruding 3 or groove 4 adds the degree of roughness of film surface, and then the frictional force between cell piece and glued membrane is increased, prevent cell piece at lamination, and effectively can control the spacing of cell piece and cell piece, avoid in component lamination process cell piece fragmentation or the problem such as cell piece spacing is too small.
Can spacing size between adjacent strip projected parts 2 be arranged to equal with cell piece width, make cell piece can be made just to be stuck between strip projected parts during component package, effectively can control the spacing of cell piece and cell piece.
The surface of strip projected parts 2 can be matsurface, to increase roughness further.
The cross section of described strip projected parts 2 can be rectangle, triangle, semicircle, trapezoidal or other is irregularly shaped arbitrarily.
Described glued membrane is EVA adhesive film or polyolefin adhesive film.
Content described in this specification embodiment is only the citing of the way of realization to utility model design; protection range of the present utility model should not be regarded as being only limitted to the concrete form that embodiment is stated, protection range of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
