Abstract
The utility model discloses a screen plate special for improving shaping of a grid line. The screen plate special for improving shaping of the grid line comprises a frame, a steel plate, a main grid line graph and an auxiliary grid line graph. The thickness h of a steel screen is 15-20 micrometers, an auxiliary grid line is composed of a plurality of rectangular holes, the length y of each rectangular hole is 600-1000 micrometers, the width x of each rectangular hole is 25-50 micrometers, the thickness h1 of each rectangular hole is h/2, and the distance a between every two adjacent rectangular holes is 10 micrometer. A main grid line of the steel screen plate is composed of a plurality of round holes which are connected tightly. The diameter d of each round hole is 35-45 micrometers. The distance h between every two adjacent round holes in the same row is 3-5 micrometers. The distance H between every two adjacent round hole rows is 3-5 micrometers. The screen plate special for improving shaping of the grid line has the advantages that shaping of the grid line is greatly improved, the height to width ratio of the grid line is increased by over 6%, and the print quality problems such as line breakage and knot forming are solved.
Description
Technical field
The utility model relates to the crystal silicon solar batteries sheet and manufactures field, relates to particularly a kind of being exclusively used in and improves the moulding half tone of grid line.
Background technology
In crystal silicon solar batteries sheet manufacturing process, serigraphy is to produce one of important procedure of crystal silicon solar batteries sheet, and its printing quality directly determines the technical indicator of cell piece.In addition, the cost of sizing agent that silkscreen process is used occupies more than 80% of whole cell piece manufacturing cost, and wherein the cost of positive silver paste accounts for more than 50% of whole cost.In the design of the positive electrode half tone of prior art, the half tone material is silk screen and photoresists, and wherein web material has two kinds of stainless steel and nylon.Easily produce the problems such as broken string, node when this kind of material prints in large-scale production process, and be unfavorable for the accumulation of slurry, do not reach good moulding.Therefore, how, under the prerequisite of the photoelectric transformation efficiency that improves the crystal silicon solar batteries sheet, reduce printing unit consumption and the quality of positive silver, reach the purpose reduced production costs, become the hot issue of research in industry.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of being exclusively used in to improve the moulding half tone of grid line, thereby it is moulding further to improve grid line, reaches the purpose of problems such as solving broken string, node.
The technical scheme that the utility model adopts is: a kind of being exclusively used in improved the moulding half tone of grid line, comprises framework, steel plate, main grid line and secondary grid line figure, and the thickness h of described steel mesh is 15～20um; Described secondary grid line is that some rectangle holes form, and the rectangle hole is of a size of length y=600～1000um, width x=25～50um, thickness h 1=h/2, adjacent two rectangle hole spacing a=10um; Described steel mesh edition owner grid are by some closely connected circular openings, diameter d=35～45um, and same row is adjacent, and two circular hole spacing h are 3～5um, adjacent two row's circular hole spacing H are 3～5um.
The beneficial effects of the utility model are that effectively to improve grid line moulding, and the grid line depth-width ratio improves more than 6%, solve the printing quality problems such as broken string, node.
The accompanying drawing explanation
Being exclusively used in that Fig. 1 the utility model provides improves the moulding half tone figure of grid line
Being exclusively used in that Fig. 2 adopts the utility model to provide improves grid line figure in the moulding half tone of grid line
In figure: x, y represents respectively length and the width of rectangle hole; A represents the spacing of adjacent two rectangle holes
The structure chart that is exclusively used in main grid line in the moulding half tone of raising grid line that Fig. 3 adopts the utility model to provide
In figure: d represents the diameter of each aperture; H represents adjacent two the circular hole spacings of same row; H represents adjacent two row's circular hole spacings.
The specific embodiment
The technical scheme of implementing below in conjunction with 1,2,3 pairs of the utility model of accompanying drawing is described in further detail.
In present embodiment, to the silicon chip of same batch, adopt identical preparation technology, but adopt different positive electrode half tones to be printed in silkscreen process, and its result is detected and comparative analysis.It is as follows that being exclusively used in of adopting the utility model to provide improved the moulding half tone design parameter of grid line: the thickness h of steel mesh is 20um, the rectangle hole of carve width x=30um, length y=800um on steel mesh, rectangle hole spacing a=10um and thickness h 1=10um; On steel mesh edition owner grid line, be to be engraved as circular opening, diameter d=40um, same row is adjacent, and two circular hole spacing h are 3um, adjacent two row's circular hole spacing H are 3um.Adopt the parameter of traditional screen mesh printing plate as follows: the order number is 360, and wire diameter is 16um, and thickness is 15 ± 1um, and tension force is 28 ± 1N.As shown in table 1 by 3D microscope test result, the depth-width ratio of steel mesh screen painting grid line on average exceeds 8.19% than screen mesh printing plate, and there is no broken string, node problem in the slice, thin piece of printing.
