Detailed description of the invention

Hereby about detailed content of the present utility model and technology illustrate, now further illustrate with embodiment, but it is to be understood that these embodiments are only the use illustrated, and should be interpreted as the restriction of the utility model enforcement.

Refer to Fig. 4 and Fig. 5, be respectively the schematic diagram that the utility model printing stencil is stressed, the present embodiment is graphic with the printing steel version 200 (as shown in Figure 4) of discontinuous finger electrode, and the printing steel version 200 (as shown in Figure 5) of continous way finger electrode is illustrative examples.The utility model discloses a kind of printing screen frame structure, be applied to the printing stencil of steel version printing, this printing stencil structure at least comprises a framework 100, this framework 100 center is provided with a printing steel version 200, be connected with a supporting network 130 between this framework 100 with this printing steel version 200, (centre of supporting network 130 is provided with opening, and opening part is provided with this printing steel version 200).

This printing steel version 200 is provided with a plurality of material-dropping hole 210, it is characterized in that this framework 100 has two the first frames 110 arranged in parallel and two the second frames 120 arranged in parallel, the length direction of these two the first frames 110 is identical with print direction 500, these two the first frames 110 and these two the second frames 120 between two vertical connection form rectangular framework 100, and the length ratio of this second frame 120 and this first frame 110 is between 1:1.1 to 1:2; And the shape being positioned at this printing steel version 200 of these supporting network 130 central authorities is rectangle, there are two the first peripheries 201 arranged in parallel, and the second periphery 202 that two arranged in parallel, the length direction of 2 first peripheries 201 of printing steel version 200 is identical with print direction 500,2 second peripheries 202 are vertical with aforementioned first periphery 201, and this second periphery 202 is 1:1 to 1:2 with the length ratio of this first periphery 201.

Because this framework 100 length of side is unequal, this framework 100 second frame 120 is greater than the supporting network width W 2 of this first frame 110 to this printing steel version 200 first periphery 201 to the supporting network width W 1 of this printing steel version 200 second periphery 202.Make the first stress 300 between this framework 200 second frame 120 and this printing steel version 200 second periphery 202 can be greater than the second stress 400 between this framework 200 first frame 110 to this printing steel version 200 first periphery 201.

Be the printed and formed schematic diagram of Fig. 4 printing stencil referring again to Fig. 6, Fig. 6.In enforcement, printing stencil is covered on a substrate 600, then by slurry with print direction 500, the length direction along the first frame 110 is scraped and is printed off printing main body 610 on this substrate 600.Because the material-dropping hole 210 of discontinuous finger electrode and continous way finger electrode image is all belong to elongated square, during printing, the length direction of finger electrode image is also identical with print direction 500, often cause the two ends of the material-dropping hole 210 of elongated square chart picture in printing process because understrressing, cannot bear and pull power when scraping slurry, produce the phenomenon of warpage, this printing steel version 200 cannot steadily and uniformly be covered on this substrate 600, when scraping slurry, slurry easily penetrates into warpage place, causes the anamorphose printed out.

Namely the utility model is relying on the length of the first frame 110 changing framework 100 to elongate the second edge 120 and is printing the distance (supporting network width W 1) between steel version 200 second periphery 202, upper at microscler net frame structure, lower and left, right employing does not wait and designs to tension structure, make the supporting network 130 shape and then variation being arranged at framework 100 inner edge, the width of supporting network width W 1 is greater than the width of supporting network width W 2, and the stress 300 that this supporting network 130 produces is larger, more not easily disperseed by the power that stress 400 and scraper scrape slurry, printing steel version 200 is made to maintain tight stable state, substrate can be covered uniformly, improve fluency when slurry scrapes, the thickness and the shape that maintain printing main body 610 make printing main body 610 not because of slurry diffusion, splash and being out of shape.Therefore, this microscler mount structure design effectively suppresses to produce because finger-like electrode pattern in printing process produces the phenomenons such as slurry splash, diffusion, uneven thickness because of distortion.

More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall in protection domain of the present utility model.
