Abstract

The utility model provides a crystalline silicon solar cell sheet multipurpose series welding template and belongs to the technical field of solar cells. The utility model resolves a problem of single function of a conventional series welding template. The crystalline silicon solar cell sheet multipurpose series welding template comprises a long-bar-shaped template. A long row of position-limiting protruding blocks are fixedly connected with the edge of a long side of the template. The template is equipped with a plurality of embedding groove structures corresponding to the sizes of cell sheets with different sizes. The embedding groove structure is composed of multiple columns of embedding groove groups which are arranged at equal intervals and which are disposed vertical to the position-limiting protruding blocks. The series welding template also comprises embedded springs. When series welding is executed on the cell sheets with different sizes, the embedded springs are inserted into various columns of embedding groove groups of a corresponding embedding groove structure. The crystalline silicon solar cell sheet multipurpose series welding template has an advantage of being suitable for carrying out series welding on the cell sheets with different sizes.

Description

The multiplex series welding mould of a kind of crystal silicon solar cell sheet

Technical field

The utility model belongs to technical field of solar batteries, relates to the multiplex series welding mould of a kind of crystal silicon solar cell sheet.

Background technology

In the use for crystal silicon solar cell sheet, because monolithic voltage is less, can't meet the use of most of occasion, need to carry out booster tension by the series connection of monolithic battery sheet, this technique need to use series welding to produce with template.

In existing production process, the series welding mould that uses carries out single formulation according to the cell piece size, processing is comparatively simple like this, size design is comparatively accurate, but the main problem that exists is: the cell piece for different size can not be suitable for, and must change corresponding template, just can use, so just cause a large amount of preparations of template, cause the increase of production cost.

Summary of the invention

The purpose of this utility model is to have the problems referred to above for existing technology, the cell piece that has proposed the applicable multiple different size of a kind of energy multiplex series welding mould of crystal silicon solar cell sheet of welding of connecting.

the purpose of this utility model can realize by following technical proposal: the multiplex series welding mould of a kind of crystal silicon solar cell sheet, comprise elongated template, the long limit of described template one edge is fixed with long row's spacing block set, it is characterized in that: on described template, offer some covers embedded groove structure corresponding with the cell piece size of different size, described embedded groove structure forms by the multiple row spaced set and with the vertically disposed embedded groove group of above-mentioned spacing block set, described series welding mould also comprises the embedded shell fragment of a cover, when carrying out cell piece to different size while carrying out series welding, described embedded shell fragment is inserted on each row embedded groove group of that corresponding cover embedded groove structure.

In the above-mentioned multiplex series welding mould of a kind of crystal silicon solar cell sheet, described embedded groove group consists of the embedded groove of three equidistant settings in column.

In the above-mentioned multiplex series welding mould of a kind of crystal silicon solar cell sheet, the thickness of described embedded shell fragment is 1mm, and the distance between the adjacent two row embedded grooves in described every cover embedded groove structure is than the large 1mm of the size of the cell piece of correspondence.

compared with prior art, the multiplex series welding mould of this crystal silicon solar cell sheet has designed the embedded groove structure that the cell piece that can be suitable for multiple different size size carries out series welding on same template, when changing the cell piece of different size, only the embedded shell fragment on the embedded groove of corresponding other sizes need be extracted, then be inserted into generating in should the embedded groove of size cell sheet series welding mould that should the size cell sheet, and do not need to change to special-purpose series welding mould that should the size cell sheet, thereby make same template can be suitable for the series welding of the cell piece of multiple different size size, when increasing work efficiency, also saved the cost that is equipped with a template to the cell piece of each size.

Embodiment

Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

as Fig. 1, 2, 3, 4, shown in 5 and 6, the multiplex series welding mould of this crystal silicon solar cell sheet comprises elongated template 1, the long limit of template 1 one edge is fixed with long row's spacing block set 2, on template 1, offer the quadruplet embedded groove structure corresponding with the cell piece size of different size, the cell piece that this quadruplet is corresponding is of a size of 156mm cell piece (as Fig. 2), 125mm cell piece (as Fig. 3), 1/2 156mm cell piece (as Fig. 4) and 1/2 125mm cell piece (as Fig. 5), the series welding mould of the present embodiment can also be offered the 125mm of correspondence 1/3 and 1/3 156mm cell piece in the above except corresponding these four size cell sheets, 1/4 125mm and 1/4 156mm cell piece, the embedded groove structure of 1/6 125mm and 156mm cell piece of 1/6 etc., Fig. 2, Fig. 3, the structure of Fig. 4 and Fig. 5 is from peeling off out Fig. 1.The embedded groove structure forms by the multiple row spaced set and with the vertically disposed embedded groove group of spacing block set 2, series welding mould also comprises the embedded shell fragment 4 of a cover, when carrying out cell piece to different size while carrying out series welding, described embedded shell fragment 4 is inserted on each row embedded groove group of corresponding that cover embedded groove structure, every group of embedded groove group consists of the embedded groove 3 of three equidistant settings in column.

For the ease of being described, it is example that the series welding cell piece is taken the 125mm cell piece, and in type design, cell piece and cell piece spacing are 2mm.To on each row embedded groove 3 of the embedded groove structure of corresponding 125mm cell piece, all insert embedded shell fragment 4, on template 1, to the spacing of adjacent each row embedded groove group in should the embedded groove structure of 125mm cell piece, be the 126mm, embedded shell fragment 4 thickness are 1mm, weld on unified alignment left side or right side in 125mm cell piece row string process, can guarantee that like this cell piece spacing is 2mm.When needs carry out 156mm cell piece series welding, only need the embedded shell fragment 4 on each embedded groove 3 of all corresponding 125mm cell pieces is all extracted the interior series welding mould that can generate corresponding 156mm cell piece of each row embedded groove 3 of the embedded groove structure that is inserted into corresponding 156mm cell piece, when producing the switching cell piece, do not need like this integral replacing series welding mould, can reduce the demand of producing for series welding mould, reduce costs.

Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
