The position accuracy demand of grid is higher, and in order to obtain higher making precision, the silk screen used by serigraphy mostly adopts composite web
Version, composite halftone is a kind of pair of screen cloth material being composited by organic screen cloth and wire gauze (such as stainless steel mesh cloth)
Half tone, is coated with emulsion on the wire gauze, the drying of emulsion, exposure, imaging is subsequently sequentially carried out again and was waited
Journey, just forms a dielectric layer (emulsion for not being washed off and hardening) for having predetermined pattern on wire gauze, that is, complete
The making of half tone.In printing, (warp and parallel work out the net to be formed to hole of the liquid such as ink on wire gauze
Hole) and area of the pattern, so as to by graphic printing on printed article.
Traditional solar battery sheet as shown in Figure 1, it includes multiple vertically arranged main grid K1, vertically arranged Jing
The parallel K3 of line K2 and horizontally set, wherein, warp and parallel are thin grid, and are mutually perpendicular to.It should be clear that the width of thin grid is very narrow
Narrow, such as only 15um, when corresponding solar battery sheet type metal composite halftone is designed, allows the liquid Jing such as ink
The recess hole P (medium layer pattern) of the design of following an example crossed is designed as accordingly 15um (ignoring design tolerance here), such as Fig. 2 institutes
Show, the half tone includes recess hole P and woven wire, recess hole and is located at parallel to the silk thread R of two adjacent one metal wire nets
The center position of two silk threads, this for perfect condition low groove position, but due to two adjacent silk threads spacing also compared with
It is little, such as 30um, because recess hole is large number of, some recess holes are difficult the center position for being accurately opened in two silk threads,
Usually occur that recess hole opens inclined phenomenon, or even, silk thread blocks the phenomenon in part recess hole.Thus, in printing, ink exists
The figure formed on printed article after hole and area of the pattern on wire gauze must occur distortion phenomenon (figure
Shape falls a part by silk thread " eating "), or even there is more serious distortion phenomenon, i.e. the width of figure (thin grid) is substantially only fluted
The half of width, thus, product must be underproof.
Therefore, how a kind of solar battery sheet type metal composite halftone is provided, the solar energy produced can be avoided
There is the state of serious distortion in cell piece, and ensures the normal usage function of cell piece, becomes current problem demanding prompt solution.

Specific embodiment
Below in conjunction with the accompanying drawing in the present embodiment, the technical scheme in embodiment is carried out specifically, clearly and completely retouch
State.
Referring to shown in Fig. 3-5, the utility model embodiment provides a kind of solar battery sheet type metal composite halftone,
Including woven wire and organic silk screen, woven wire is located in the region emptied in the middle of organic silk screen, is formed on woven wire
Have effigurate pattern medium layer, woven wire includes warp R2 and the parallel R1 for being mutually perpendicular to interweave, wherein, pattern is situated between
Matter layer formation process is：Emulsion is coated with the wire gauze, the drying of emulsion is subsequently sequentially carried out again, is exposed
The processes such as light, imaging, just form on a wire mesh described pattern medium layer (emulsion for not being washed off and hardening)
Fig. 3 is the structural representation of the pattern medium layer of solar battery sheet type metal composite halftone, wherein, in figure
Cell body represents that pattern medium layer is included for printing the major trough P1 of the vertical main grid of shaping, for printing shaping laterally carefully with lines
The translot P2 of the grid and skewed slot P3 for the oblique thin grid of printing shaping, the size of major trough P1 matches with the size of main grid, translot
The size of P2 matches with horizontal thin grid, and the size of skewed slot P3 matches with the size of oblique thin grid, wherein, translot P2 is vertical simultaneously
Connection major trough P1, skewed slot P3 intersect and are formed angle α or β, -80 ° of angle α/β=10 °, and alpha+beta=180 °, major trough with translot P2
P1 parallel to warp R2 bearing of trend, translot P2 parallel to parallel R1 bearing of trend, skewed slot P3 also with parallel R1 extension sides
To angle α or β is formed, so that multiple nodes that the intertexture of parallel R1 and warp R2 is formed expose (ginseng from skewed slot P3
As shown in Fig. 4-5).
Preferably, angle α/β is 20 ° -60 °.Further, angle α/β is 45 °, 22.5 ° or 30 °.
Preferably, skewed slot P3 is arranged by several unit skewed slot P31 being placed equidistant along warp R2 bearing of trends continuity
And formed, the vertical range between two adjacent unit skewed slot P31 is consistent with the distance between two adjacent translot P2.It is excellent
Choosing, woven wire adopts stainless steel cloth, organic silk screen to adopt terylene silk net.
Vertical slot for the vertical thin grid of printing shaping of the prior art is changed into skewed slot P3, skewed slot P3 by the utility model
Angle α or β are formed with the parallel R1 bearing of trends of woven wire, -80 ° of angle α/β=10 °, thus, design can allow parallel R1
The multiple nodes formed with the intertexture of warp R2 expose from skewed slot P3, and in printing, ink first passes through woven wire, then Jing
Skewed slot P3 is crossed so as to form pattern on printed article, because skewed slot P3 favours the design of parallel R1 bearing of trends, so as to avoid
Cell body of the prior art is blocked by whole piece parallel R1, and then the pattern excalation that causes to print out and caused serious distortion
Phenomenon.In the utility model, parallel R1 and warp R2 is not in the phenomenon that whole piece blocks skewed slot P3, and parallel R1 and warp R2 are only
Only partial occlusion skewed slot P3, and the node of longitude and latitude line R1 has blocked skewed slot P3, and the figure formed on printed article occurs
Concave point, but the shape of whole figure is complete, that is, be not in more serious distortion phenomenon.Design by more than, this practicality
It is new by the way that original vertical slot is designed as into skewed slot P3, such that it is able to print out inclined thin grid, that is to say, that can print out
(solar battery sheet includes many solar battery sheet consistent with the structural representation of pattern medium layer as shown in Figure 6
The thin grid K3 of individual vertically arranged main grid K1, the thin grid K4 being obliquely installed and horizontally set), incline the complete of thin grid so as to ensure that
Whole structure, and then ensure that the conductive effect of solar battery sheet.
Above-mentioned specific embodiment, only illustrates technology design of the present utility model and architectural feature, it is therefore intended that allow ripe
Knowing the stakeholder of technique can implement according to this, but above said content is not intended to limit protection domain of the present utility model,
Every any equivalence changes made according to Spirit Essence of the present utility model or modification, all should fall into protection of the present utility model
Within the scope of.
