Abstract
The utility model discloses a caterpillar band for supporting solar cell sheet in sintering furnace, which includes multiple parallel horizontal strips arranged in the same horizontal plane and multiple longitudinal strips connected between adjacent horizontal strips, wherein the longitudinal strips are distributed on both ends of the horizontal strips. Each horizontal strip is bent to form two epirelief bulges, the distance between the tops of the two bulges of the each horizontal strip is greater than the width of the solar cell sheet, and the minimum distance between the bottoms of the two bulges of the each horizontal strip is less than the width of the solar cell sheet. The utility model adopts the above structure to achieve simple whole structure and easy realization, and when using the utility model to support the solar cell sheet, the aluminum back surface field of the solar cell sheet is not in contact with the utility model, so as to avoid defect of uneven heating of the aluminum back surface field caused by contact between the aluminum back surface field and the caterpillar band.
Description
Technical field
The utility model relates to solar cell sintering technology field, specifically is the crawler belt that is used for sintering furnace supporting solar battery sheet.
Background technology
Solar battery sheet through serigraphy after; All will be placed on the crawler belt and be transported to and carry out sintering in the sintering furnace through crawler belt; For the ease of crawler belt the battery sheet is supported; Existing sintering furnace crawler belt is provided with the raised points of a plurality of protrusion track surface, contacts with the aluminium back of the body field of battery sheet through the raised points summit, and then the battery sheet is held up.Contact with the convexity of crawler belt because of the aluminium back of the body field of battery sheet is local; The contact position of the battery sheet aluminium back of the body and the non-contacting position inequality of being heated; Therefore, adopt existing structure people crawler belt supporting battery sheet and carry out sintering to have following defective: battery sheet Ohmic contact variation can influence the electrical property of battery sheet; Because of the battery sheet aluminium back of the body field inequality of being heated, the stress of a battery sheet aluminium back of the body diverse location is different and be prone to bend, be out of shape, and then causes common " arculae " phenomenon; Battery sheet aluminium back of the body field links to each other with convexity through the sintering furnace high temperature melt earlier with the aluminium of crawler belt contact position, when fast cooling, separates out with convexity again and separates, and in this process, is prone to produce " aluminium thorn ", and then can influences battery sheet quality.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; Provide a kind of can avoiding when being used to support solar battery sheet contact, be used for the crawler belt that sintering furnace supports solar battery sheet uniformly thereby the aluminium back of the body field of solar battery sheet is heated with the aluminium back of the body of solar battery sheet.
The purpose of the utility model mainly realizes through following technical scheme: the crawler belt that is used for sintering furnace supporting solar battery sheet; Comprise that many are arranged on the same horizontal plane and the horizontal stripe that is parallel to each other; Be connected with many taeniaes between adjacent two horizontal stripes in said many horizontal stripes, many taeniaes are distributed in the two ends of horizontal stripe; The equal bending of said many horizontal stripes constitutes the convexity of two epireliefs, and the distance in every horizontal stripe between two protruding summits is greater than the width of solar battery sheet, and in every horizontal stripe the minimum range between two bump bottom ends less than the width of solar battery sheet.Many horizontal stripes in the utility model have constituted the basic framework of the utility model, and connect the intensity that horizontal stripe has strengthened the utility model through taeniae.The convexity of the utility model also can be processed by iron wire in advance, and the mode through welding is welded on the horizontal stripe again, and for the ease of making, the utility model preferably is made up of convexity the horizontal stripe bending.
Two convexities in said every horizontal stripe lay respectively at the both sides at horizontal stripe center, and said convexity comprises two arc supports, and the radian of protruding support near the horizontal stripe center is less than the radian of convexity away from the support at horizontal stripe center.When adopting the utility model supporting solar battery sheet, solar battery sheet is placed on the protruding arc support, specifically is placed on the less support of protruding radian relatively.It is less that the support that the utility model convexity supports solar battery sheet is set to radian; And that another support is set to radian is bigger; This is that the support that radian is bigger is convenient to carry stressed and is difficult for making bulging deformation because the less support of radian is convenient to the placement of solar battery sheet.
Be placed in the sintering furnace in order to save manufacturing cost and to be convenient to the utility model, as preferably, the height of said convexity is 1～3cm.
Compared with prior art, the utlity model has following beneficial effect: the utility model comprises many horizontal stripes and taeniae, and many equal bendings of horizontal stripe constitute the convexity of two epireliefs; Distance in every horizontal stripe between two protruding summits is greater than the width of solar battery sheet; And the minimum range in every horizontal stripe between two bump bottom ends is less than the width of solar battery sheet, and the utility model adopts said structure, and overall structure is simple; Be convenient to realize; During through the utility model supporting solar battery sheet, the seamed edge of the relative both sides of solar battery sheet contacts with the support of two convexities in the horizontal stripe, and the aluminium of solar battery sheet back of the body field can not contact with convexity; So; Aluminium back of the body field is heated evenly when solar battery sheet is carried out sintering, thereby has improved the electrical property of solar battery sheet, and can reduce the probability that " arculae " and " aluminium thorn " produces.
