Abstract
The utility model discloses a filler strip used in solar module lamination, wherein the cross section of the filler strip is rectangular, and the thickness of the filler strip is less than the thickness of a solar module to be laminated by 1-2 mm. The module to be laminated can be surrounded by the filler strip, so that a concentrated force bearing point is transferred to the filler strip in lamination, lateral pressure originally applied at the edge of the module disappears, and pressure on all parts of the module is uniform in the lamination, so as to avoid the situations of degumming, bubbles, cell slice shifting, module damage and the like, improve the yield, and greatly reduce the manufacturing cost.
Description
Technical field
The utility model relates to the frock in a kind of solar module manufacturing field, is specifically related to a kind of filler strip that is used for lamination of solar battery components.
Background technology
At present, the lasting use of conventional energy resource has brought a series of economy and social concerns such as energy scarcity and ecological deterioration, the development solar module be address the above problem by way of one of.
Preparation technology's flow process of existing solar module is: sorting, single weldering, series welding, lamination preparation, lamination, general assembly.Wherein, decision product final effect is the lamination operation.
Existing laminating method is: lay not sticky cloth at the warm table 3 of laminating machine earlier, the solar module 2 that directly will treat lamination then is put on the not sticky cloth of laminating machine warm table, cover not sticky cloth 1 at the assembly end face then, configure laminating parameters, directly carry out lamination after closing lid.Pressing plate during lamination on the laminating machine is added in the distribution map of the power on the assembly shown in Fig. 1 ~ 2, because assembly edge not only is subjected to the vertical force from top to down that laminating machine is given, but also be subjected to lateral pressure from silica gel plate, according to the parallelogram of forces rule, be added in all bigger than in these two power any one with joint efforts of two power on the object, therefore the power that four edges of assembly are subjected to during lamination all big than other places, form and concentrate stress point, and the EVA/PVB of assembly edge under the effect of big pressure as easy as rolling off a log be extruded to produce come unstuck, side force easily makes glass bend and causes doubling layer bubble, flowability when being extruded owing to PVB/EVA simultaneously is bigger, the as easy as rolling off a log generation of locating under the effect of this mobilization force of battery sheet that keep to the side is shifted, even the big stress that edge is subjected to can cause the assembly breakage, safety glass edge particularly, its stressed cracky, thus the qualification rate and the production efficiency of assembly reduced, increased manufacturing cost.
Summary of the invention
The utility model purpose provides a kind of filler strip that is used for lamination of solar battery components, to improve the qualification rate of assembly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of filler strip that is used for lamination of solar battery components, the cross section of described filler strip are rectangle, and the thickness of filler strip is than little 1 ~ 2 mm of thickness of the solar module for the treatment of lamination.
In the technique scheme, described filler strip is a rubber strip.
In the technique scheme, described filler strip is made of at least 2 layers of stacked cementation of silica gel plate.Promptly can be with the silica gel plate of scrapping, to realize twice laid.
In the technique scheme, the width of described filler strip is 50 ~ 60 mm.
Filler strip be located in the solar module for the treatment of lamination around, it encloses structure and is: 4 filler strips are located at one side of assembly successively, and an end of each filler strip is concordant with one side of assembly, and the other end exceeds outside the assembly.4 filler strips surround a complete rectangle frame the described solar module of lamination for the treatment of are surrounded.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, filler strip of the present utility model can be located in treat laminated compenent around, thereby when lamination, concentrated stress point is transferred on the filler strip, originally the lateral pressure that was added in assembly edge disappears, during lamination on assembly everywhere power all be uniform, thereby avoided coming unstuck, situation such as bubble, the displacement of battery sheet, assembly breakage, improved yield rate, greatly reduced manufacturing cost.
2, filler strip of the present utility model can adopt laminating machine can make with useless silica gel plate, and raw material is easily available, and production cost is extremely low, also realizes the utilization again of laminating machine waste material simultaneously.
3, of the present utility model simple in structure, be easy to preparation, cost is lower, is suitable for applying.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one
Shown in Fig. 3 ~ 5, a kind of filler strip that is used for lamination of solar battery components, the cross section of described filler strip are rectangle, and the thickness of filler strip is than little 1 ~ 2 mm of thickness of the solar module 2 for the treatment of lamination.The width of filler strip is 50 ~ 60 mm.
Filler strip can be that special rubber strip also can be the useless silica gel plate (realization twice laid) of laminating machine, its length can be sheared according to the length component situation, also several filler strip strings can be spread realization and require length (filler strip length and length component are suitable), its thickness can regulate that (general filler strip thickness is than the component thickness for the treatment of lamination thin 1 ~ 2mm) with the rubber slab or the silica gel plate of the fixing different numbers of plies of adhesive tape.
The lamination schematic diagram of solar module is referring to shown in Figure 3,4 one side of being located at the solar module 2 for the treatment of lamination successively of 4 pads, one end of each filler strip is concordant with one side of the described solar module for the treatment of lamination, and the other end exceeds outside the solar module for the treatment of lamination.In order to guarantee to vacuumize preferably effect, filler strip is generally 10mm, 15mm, 20mm apart from the assembly certain distance, can be according to the actual conditions adjustment.
Stressed schematic diagram during lamination is referring to shown in 4 ~ 5: after laying filler strip, concentrate stress point to transfer to (as shown in Figure 5) on the filler strip during lamination, originally the lateral pressure that was added in assembly edge disappears, during lamination on assembly everywhere power all be uniform, come unstuck, the situation of the displacement of bubble, battery sheet, assembly breakage can avoid greatly, the problem that has run into when having solved above-mentioned lamination has improved yield rate, greatly reduces production cost.
