Brief description
With reference to appended accompanying drawing, more fully to describe embodiment of the present utility model.However, appended accompanying drawing is only used for
Bright and illustrate, do not constitute the restriction to this utility model scope.
Fig. 1 is the structural representation of just silver-colored half tone in the embodiment of the present application（Note：The thin grid line of in figure only display portion and frame
Line, wherein main gate line are omitted）；
Fig. 2 is based on the structural representation arranging frame line on the basis of Fig. 1 in Printing Zone；
Fig. 3 is the enlarged diagram of part-structure in Fig. 2.
Specific embodiment
Just silver-colored half tone shown in Figure 1, in the present embodiment, can apply in the typography of crystalline silicon battery plate, this is just
Silver-colored half tone 1 specifically may include screen frame 2 and is fixed on the screen cloth 3 among this screen frame 2 by connecing mode；For example, 90 ° of angles can be adopted
Or above-mentioned screen cloth 3 is fixed among screen frame 2 mode of throwing the net of 180 ° of angular direction, can be used for preparing crystal silicon cell to be formed
The just silver-colored half tone 1 of piece.
Further, above-mentioned screen cloth 3 may include the Printing Zone 32 being arranged on centre position and around this Printing Zone 32
Non-printing district 31, and the first steel wire 322 of some horizontally-parallel extensions can be set in Printing Zone 32 and some longitudinal directions are put down
The second steel wire 321 that row extends（I.e. the first steel wire 322 and the second steel wire 321 are mutually perpendicular to）, and the first steel wire 322 and the second steel
Silk 321 interlacings are network structure, and this network structure includes the net tie region of net knot and the no net tie region no netting knot（Figure
In do not indicate）；For example, the first steel wire 322 and the second steel wire 321 are mutually perpendicular to interlacing to constitute the net for follow-up printing
Shape structure；In addition, the thin grid line area 333 of some strips is provided with screen cloth 3, and all only it is distributed in arbitrary thin grid line area 333
There is the steel wire of one of the first steel wire 322 and the two kinds of steel wire of the second steel wire 321 type, that is, in thin grid line area 333
There is not the net knot that the first steel wire 322 and the second steel wire 321 interweave（Ji Xi grid line area 333 is arranged on above-mentioned no net interface
In）, so subsequently carry out in this thin grid line area 333 thin grid line printing when, and can effectively avoid because of traditional net knot
Presence and the such as thin grid line that causes linearly not enough depth-width ratio and the not high defect of linear stationarity so that printing slurry energy
Enough more easy seepages in thin grid line area remaining with net tuberosity point compared to tradition, and then lift the line of the thin grid line of preparation
The key parameters such as property, depth-width ratio and stability, to lift transformation efficiency and the service life of half tone.
Preferably, all non-contacting between the thin grid line area 333 of above-mentioned some strips extend parallel to each other, and in screen cloth
On can be provided with 80 ~ 130 be parallel to each other and non-contacting strip thin grid line area 333（Specific number can be according to actual
Printing demand and set）.
Preferably, the width in the thin grid line area 333 of arbitrary strip all can be 20 ~ 350 μm, and the material of screen frame then can adopt
Aluminium alloy.
Further, referring to shown in Fig. 1 ~ 3, along print direction both sides in the Printing Zone 32 on above-mentioned screen cloth（Hang down
Directly in thin grid line area 333）It is respectively arranged to griffe at least two rim area of position and lower cutter position（In figure does not indicate）And
Multiple regions such as the area that thin grid contact with main grid, in all regions that above-mentioned and thin grid line area 333 is contacted, itself and this thin grid line
It is respectively positioned on the region beyond the first steel wire 322 and the second steel wire 321 node, such as institute in Fig. 1 ~ 3 at the contact point of area 333 contact
Show, in the thin grid line B being formed using half tone 1 on screen cloth 3（Correspond to and be located in thin grid line area 333）And frame line C between
Also no above-mentioned net tuberosity point in region corresponding to contact point A.
Preferably, above-mentioned screen cloth 3 can be using jump braiding（As based on 1 ~ 6 twine that jumps on the basis of traditional half tone
To constitute above-mentioned thin grid line area 333）The screen cloth prepared of mode, and the material of the first steel wire 322 and the second steel wire 321 is then equal
It can be rustless steel.
In addition, as shown in Fig. 1 ~ 3, due to for griffing position and the frame line of lower cutter position can be intermittently through there being net
The net tie region of knot and no net tie region, and due to the strike through with respect to no net tie region at steel wire site position in net tie region
Property poor, the formed frame line thickness of printing can be made uneven, and then lead to the device performance prepared unstable；In order to carry
Rise the uniformity of frame line, the narrowed width at position that can contact rim area with thin grid line area 333, to improve the side of preparation
The overall uniformity of wire；Preferably, width rim area being located at no in net tie region is set smaller than rim area and is located at
Width in net tie region；Further, can be with arbitrary rim area and thin grid line area contact position as starting point（As A）, along to
Rim area two ends bearing of trend（As along frame line C both ends bearing of trend）So that the width of rim area is gradually increased, and then shape
Become the linear of gradual change, with the even thickness of the further entirety optimizing the formed frame line C of printing.
In the present embodiment, due in region specific on screen cloth using such as reeling off raw silk from cocoons and/or braiding of jumping（As knitted
There is discontinuous to select knitmesh during net, knit out the screen cloth similar to half tone figure）Mode be set to no net the region of knot,
And can adopt the angle of throwing the net at 90 ° or 180 ° angles, to prepare, lower cutter position occurs in half tone, and the no net tie region of this half tone
Or when griffing position, its contact point with thin grid line area is the structure of gradual change, and then to keep the stability of live width, and then
The linear more smooth of printing can be made, and depth-width ratio is relatively stable, moreover it is possible to substantially reduce slurry while lifting half tone efficiency
The slurry weight of material, thus saving process costs, the service life of lifting half tone.
For a person skilled in the art, after reading described above, various changes and modifications undoubtedly will be evident that.
Therefore, appending claims should regard the whole variations and modifications covering true intention of the present utility model and scope as.
Any and all scope of equal value and content in Claims scope, are all considered as still belonging to intention of the present utility model and model
In enclosing.
