Description
Technical field
The utility model relates to a kind of scraper for silk-screen printing.
Background technology
In solar cell industry, cell piece forms grid line and aluminium back surface field by silk-screen printing technique now.In screen printing process, by the pressure between scraper and serigraphy, make slurry on silk screen be penetrated into and on silicon chip, complete printing by mesh.In actual screen printing process, the problem usually occurring is that a large amount of slurries can be overflowed by the top from scraper, makes slurry be set in scraper outside, waste slurry.Prior art once proposed a kind of scraper, and this scraper comprises scraper body and is arranged at the first returning charge plate on scraper body, in the upper end of scraping charge level of the first returning charge plate, is provided with it vertical slurry shutter.
The major defect that the scraper of this structure exists is, because silver is starched, aluminium paste viscosity is high, in printing process, the slurry being stoped by slurry shutter can be set on slurry shutter, be difficult for being back to silk screen surface, cause printing quality, the waste slurry of biting, reduce cell piece.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provide a kind of not only can stop slurry overflow, but also the slurry that can make to stop return to rapidly the scraper for silk-screen printing in screen painting region.
For achieving the above object, the technical solution of the utility model is a kind of scraper for silk-screen printing, comprises scraper body, and the lower end of scraper body is provided with scraping article; Scraper body extends the slurry shutter that is provided with the described scraping article of covering; A side surface towards described scraping article of slurry shutter is to the arcuate structure of the internal recess of slurry shutter body, comprises the boot segment for guiding slurry to flow downward.
In order to increase the block amount of slurry shutter to slurry, preferably, the arcuate structure of the side surface towards described scraping article of described slurry shutter also comprises that, for promoting the raising section of slurry, raising section connects described boot segment and described scraper body.Raising section is set and can improves the upper limit that stops slurry, and slurry is concentrated near scraping article, reduce the exposed area that slurry contacts with air, avoid slurry too away from scraping article, to cause volatilization tackify.
In order to prevent that slurry is from the both sides overflow of scraper body, slurry is controlled in screen painting region, further preferably, the two ends, left and right of described scraper body respectively stretch out and are provided with the returning charge wing, be respectively first, second returning charge wing, described first, second returning charge wing and described slurry shutter are positioned at the same side of described scraping article, are symmetrical structure; A side surface towards the described second returning charge wing of the wherein said first returning charge wing comprises that the first cambered surface connects the second cambered surface and described scraper body to the first cambered surface of the second returning charge wing projection with to the second recessed cambered surface of the first returning charge wing body.Wherein the first cambered surface is conducive to make slurry to be concentrated to serigraphy district, and the second cambered surface is conducive to collect slurry.Further preferably, described the second cambered surface is α away from tangent line and the described scraper body angulation at the place, one end of described scraper body, wherein 90 °≤α <180 °.Wherein, described α=90 °, anti-overflow effect is best.
Further preferably, described first, second cambered surface is respectively 1/4 arc surface.It is that maximum, collecting effect are best that the baffle structure of this optimization stops amount of slurry.
In order to make can to get back to screen painting district toward the slurry of scraper body both sides overflow, preferably, the top of a side surface at the described first cambered surface place of the described returning charge wing is round and smooth connection with the side of the side surface towards described scraping article of described slurry shutter.
The length of best described slurry shutter and described scraping article equal in length.
Advantage of the present utility model and beneficial effect are: scraper for silk-screen printing of the present utility model, by the slurry shutter that inner surface is evagination arcuate structure is set above the corresponding scraping article at scraper body, slurry shutter had both played the object that stops slurry overflow, the slurry that arcuate structure guiding is simultaneously prevented from can return to rapidly screen painting main region, avoid slurry to be trapped on slurry shutter, avoid biting, having saved slurry, improved the printing quality of cell piece.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As illustrated in fig. 1 and 2, the utility model is a kind of scraper for silk-screen printing, comprises scraper body 1, and the lower end of scraper body 1 is provided with scraping article 2; Scraper body 1 extends the slurry shutter 3 that is provided with covering scraping article 2; A side surface towards scraping article 2 of slurry shutter 3 is the arcuate structure to the internal recess of slurry shutter 3 bodies, comprises for guiding boot segment 31 that slurry flows downward and for promoting the raising section 32 of slurry.Raising section 32 connects boot segment 31 and scraper body 1, can increase the amount of blocking of 3 pairs of slurries of slurry shutter, improve stop the upper limit of slurry, and slurry is concentrated near scraping article 2, reduce the exposed area that slurry contacts with air, avoid slurry too away from scraping article 2, to cause volatilization tackify.The length of slurry shutter 3 and scraping article 2 equal in length.
