Compared with the prior art, the solar battery component packaging side frame has the beneficial effects that the glue overflow phenomena are prominently improved, and the cleaning and wiping efficiency of the component is improved through improving the glueoverflowing phenomena, thereby directly reducing the possibility of battery piece hidden cracking due to cleaning and wiping.

Description

Solar module encapsulation frame

Technical field

The utility model relates to solar module and makes the field, relates in particular to the solar module encapsulation frame that assembly frames up and uses in the technical process.

Background technology

Encapsulation is the committed step in the manufacture of solar cells.Frame up as critical step in the packaging technology, play a part to increase the useful life of the intensity of assembly, further black box and prolongation assembly.Packaging technology generally is by beating adhesive process silica gel to be distributed in the frame earlier, utilize pressure with lamination again after battery component combine with frame and finish encapsulation.Because the unsteadiness of beating adhesive process at present, the assembly limitation of technology that in the process of framing up, may bend and frame up in addition, and for guaranteeing the sealing effectiveness after the encapsulation, the draw-in groove of existing solar module encapsulation frame is smaller with the gap after assembly combines, the phenomenon that has caused assembly silica gel to occur overflowing in the process of framing up.The silica gel that overflows can influence the outward appearance of assembly, needs the labor cleaning, has directly increased the cost of cleaning and has reduced the efficient that assembly is produced.Because the adhesive strength of silica gel is bigger, also can increases the latent problem of splitting of battery during cleaning, thereby cause the reduction of assembly quality in addition.

In order to improve the glue phenomenon of overflowing, the applicant's Granted publication day is on April 18th, 2007, and the patent No. is for providing a kind of large-scale solar module encapsulation frame that has glue groove as shown in fig. 1 in 200520140581.5 the utility model patent.As shown in Figure 1, be provided with the assembly draw-in groove in a side of frame 11, the assembly draw-in groove is made up of epicoele face 61, cavity of resorption face 71 and side 81, and the assembly draw-in groove is a wedge shape glue groove that bottom land is big, notch is little.In the assembly draw-in groove, place solar module 41.At the bonding part filling with sealant 21 of solar module 41 with the assembly draw-in groove.Fig. 2 is the enlarged diagram of I among Fig. 1, as shown in Figure 2, retaining glue limit 31 is set on the epicoele face 61 of assembly draw-in groove.Retaining glue limit 31 is outstanding in the assembly draw-in groove, forms protuberance.For avoiding scratching solar module 41, the cross section on retaining glue limit 31 is set to curve forms such as arc.Yet,, on the basis of practice discovery, can also do further improvement with the excessive glue phenomenon of better improvement in this structure though the structure that this utility model patent discloses can be improved the glue phenomenon of overflowing to a certain extent.

The utility model content

The utility model embodiment technical problem to be solved is, a kind of solar module encapsulation frame is provided, and reaches and improve the excessive glue phenomenon that solar module produces in the process of framing up.

For solving the problems of the technologies described above, the utility model embodiment provides a kind of solar module encapsulation frame, and it comprises the assembly draw-in groove, and described assembly draw-in groove comprises epicoele face, cavity of resorption face and side, in the inboard of described epicoele face one groove is set.

For reaching the purpose of this utility model, preferred, the opening part of described groove has first projection and second projection.

As mentioned above, further, described first distance that projects into described cavity of resorption face is greater than described second distance that projects into described cavity of resorption face.

As mentioned above, described second projection free end that is described epicoele face is towards described side one side-prominent forming.

As mentioned above, for reaching the purpose of this utility model, preferred, the bottom land of described groove is a curved surface.

As mentioned above, described assembly draw-in groove is a wedge shape glue groove that bottom land is big, notch is little.

Utilize frame of the present utility model, its beneficial effect is, can significantly improve the glue phenomenon of overflowing, and in addition, by improving the glue phenomenon of overflowing, has promoted the efficient of unit clean wiping, also can directly reduce the latent probability that splits of battery sheet.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

With reference to Fig. 3, it is the schematic section of the solar module encapsulation frame of an embodiment of the utility model.Frame 1 shown in Figure 3 is roughly the same with the structure of frame 11 shown in Figure 1, and difference is the structure of the assembly draw-in groove 5 of frame 1.

As shown in Figure 3, the assembly draw-in groove 5 of the utility model frame 1 comprises epicoele face 6, cavity of resorption face 7 and side 8, in the inboard of the described epicoele face 6 of assembly draw-in groove 5 groove 3 is set.The shape of groove 3 can be provided with arbitrarily.Preferably, as shown in Figure 4, it is the enlarged diagram of II among Fig. 3, and the opening part of groove 3 has first projection 31 and second projection 32.The setting of projection, one side can strengthen the structural strength of epicoele face 6, and on the other hand, projection itself also can play the effect as retaining glue described in the prior limit 31.Wherein, preferred, first projection 31 can be provided with greater than the distance H 2 of second projection 32 to cavity of resorption face 7 to the distance H 1 of cavity of resorption face 7.Like this, can play the effect of better retaining glue on the one hand, be beneficial on the other hand and clamp solar module 4.In addition, second projection 32 can for along the free end of epicoele face 6 towards the side 8 one side-prominent forming.The bottom land of groove 3 can be a curved surface or plane.In addition, integral body, assembly draw-in groove 5 can be a wedge shape glue groove that bottom land is big, notch is little, promptly the width of the openend of assembly draw-in groove 5 is littler than the width of bottom, can reach the effect of the excessive glue of better improvement like this, also more help clamping solar module 4.

Fig. 5 shows the solar module encapsulation frame of an embodiment of the utility model and the schematic section after the solar module assembling.According to the utility model, need not to increase any processing step, also need not to increase the purpose that any parts can reach the excessive glue phenomenon of remarkable improvement, thereby also can save the cost of solar module cleaning.In addition, border structure of the present utility model is simple, can not increase the frame production cost.

The above only is a part preferred embodiment of the present utility model, and all equivalent arrangements of being done according to the utility model claim change, all in protection range of the present utility model.
