The utility model discloses in the bracket slots with frictioning support embedding frictioning back, the frictioning support supports in the inside of frictioning, can improve the anti deformability of whole of frictioning, and then promotes the life of frictioning.
Description
Technical field
The utility model relates to photovoltaic silicon cell art, is specifically related to a kind of frictioning of the silkscreen process be used in crystal silicon solar batteries production.
Background technology
Serigraphy is one of important procedure of manufacture of solar cells, plays a part key to the final mass of cell piece.It utilizes the saturating slurry of silk screen visuals mesh, and the general principle of the not saturating slurry of non-graphic part mesh is printed.Pour slurry in silk screen one end during printing, set frictioning printing angle, apply certain pressure with frictioning at the position of silk screen, move towards the silk screen other end simultaneously.Slurry is expressed on silicon chip from the mesh of visuals by frictioning in movement.Trace set is made within limits due to the stickiness effect of slurry, in printing process, frictioning is linear contact lay with silk screen and silicon chip all the time, contact wire moves with frictioning and mobile, lifted after whole printing zone scraped by frictioning, silk screen also departs from silicon chip simultaneously, and by returning blade, slurry is gently scraped back initial position, be so far a print stroke.Wherein frictioning is expressed to slurry on silicon chip by screen mesh in the process of movement.
The printing quality of serigraphy, as thickness, width and uniformity etc., is the technical indicator affecting cell piece performance.The research and development of silk-screen printing technique are the important channels of improving solar cell transformation efficiency.Traditional serigraphy frictioning cross section is square, is installed to after on vertical type print head, and the pressure caused half tone is comparatively large, and easily occur disconnected grid and empty print in printing process, overall printing effect neither be fine.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, a kind of frictioning for crystal silicon solar batteries serigraphy is provided, promote the service life of frictioning, reduce the quick-fried version ratio of the spillage of half tone in printing process, ensure reliability and the security of serigraphy.
Technical scheme: the frictioning for crystal silicon solar batteries serigraphy described in the utility model, comprise frictioning and frictioning support, the back of described frictioning has bracket groove, and described frictioning support embeds in described bracket groove, is fixed on printing equipment by described frictioning; The two ends of the Embedded Division of described frictioning support are respectively arranged with locating notch, are provided with the locating piece matched with described locating notch in described bracket groove, and when described frictioning support embeds in described bracket groove, described locating piece embeds in described locating notch.
The utility model further preferably technical scheme is, the thickness at described frictioning back is greater than the thickness of described frictioning support, and described frictioning support runs through the length direction of described frictioning.
