Abstract
The utility model relates to a slurry filter net, and belongs to the solar cell preparation field. The slurry filter net comprises a net support and net cloth. The net support is in a square annular structure, a square annular inner cavity bonds the net cloth, and four corners of the net support are respectively provided with positioning holes. Meshes, line diameters and angle parameters of the net cloth are all in a micrometer level, and the slurry filter net can filter fragments in silver paste slurry, and therefore waste of the slurry is effectively reduced, and production cost for users is saved.
Description
[technical field]
The utility model relates to the solar cell preparation field, especially relates to a kind of silver slurry slurries filtration net that uses in silkscreen process.
[background technology]
Known, determine that the preparation section of solar battery sheet conversion efficiency is exactly silkscreen process, and use in this operation, larger and expensive material is exactly that silver is starched to the effectiveness affects of cell piece; Yet, in the preparation process of cell piece, have unavoidably some uncontrollable factors and cause silkscreen process to produce fragment, and then inevitably have fractionlet and jump to spatter and enter in the silver slurry slurry that is using; The fractionlet that contains in these slurries can puncture half tone when printing, and initiation spillage, thereby directly have influence on the printing quality of serigraphy and the conversion efficiency of cell piece, but also may have influence on service life of assembly, therefore, if contain fragment in silver slurry slurry, the user can only abandon it, do not re-use, this has not only wasted slurry, but also has increased user's production cost.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of slurries filtration net, described screen pack can filter out the fragment in silver slurry slurry, thereby has effectively reduced the waste of slurry, for the user has saved production cost.
For achieving the above object, the utility model adopts following technical scheme:
A kind of slurries filtration net, described screen pack comprises rack and screen cloth; The described rack side of being loop configuration, the inner chamber of side annular is bonded with screen cloth, and four jiaos of rack are respectively equipped with locating hole; Described screen cloth order number, wire diameter and angle parameter are micron level.
Described slurries filtration net, described grid structure are the hot-cast one-shot forming.
Described slurries filtration net, when described rack and screen cloth are bonding, the parameter tension force of all directions is 28 ± 2N.
Described slurries filtration net, described screen cloth are import stainless steel cloth screen cloth.
Described slurries filtration net, described screen cloth order number is 250 orders, and wire diameter is 30um, and the net angle that stretches tight is 22.5 °.
Described slurries filtration net, the surperficial surrounding of described screen cloth is provided with the film film that thickness is 15 ± 2um.
Owing to adopting technical scheme as above, the utlity model has following beneficial effect:
Slurries filtration web frame described in the utility model is simple, easy to use, and it can effectively filter out contained fragment in silver slurry slurry, and even those also can be continued to use by the dull slurry of abandoning after filtering through described screen pack because entering fragment; Described screen pack effectively reduces the silver that occurs and starches the phenomenon that slurry is wasted in silkscreen process, thereby has saved production cost for the user accordingly.
[description of drawings]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, rack; 2, screen cloth; 3, locating hole.
[specific embodiment]
Can explain in more detail the utility model by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;
1 described slurries filtration net by reference to the accompanying drawings, described screen pack comprises the rack 1 of being made by the one-shot forming of hot-cast technology and the silk screen screen cloth 2 that is formed by weaving by the import stainless steel; Described rack 1 is can the corresponding square loop configuration that supports half tone, is bonded with for the screen cloth 2 that filters at the inner chamber of square loop configuration, at four jiaos of locating holes 3 that are respectively equipped with for fixing described screen pack of rack 1; Bonding more firm for making, rack 1 should be made as 28 ± 2N with all directions parameter tension force of screen cloth 2 when bonding; For being able to effectively leach the purpose of fractionlet, the order number of described screen cloth 2 is made as 250 orders, and wire diameter is made as 30um, and the angle of the net that stretches tight is made as 22.5 °, and the parameter of order number, wire diameter and the angle of screen cloth 2 all will reach the accurate unit of micron level simultaneously; In addition, for water clock does not occur in the appointed area slurry of effectively controlling on described screen pack, the film film that thickness is 15 ± 2um can be set in the surperficial surrounding of screen cloth 2.
When implementing slurries filtration net described in the utility model, only need utilize the locating hole 3 on rack 1 described screen pack to be fixedly mounted on the position of corresponding size barrel, then just can the silver slurry slurry by described screen pack be filtered.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
