Description
Technical field
Manufacture of solar cells technical field is the utility model is related to, more specifically to a kind of solar battery sheet
Screen printing scraper.
Background technology
Solar cell is also known as " solar chip " or " photocell ", is a kind of photoelectricity using the sunshine direct generation of electricity
Wafer, as long as the illumination that it is satisfied certain illumination conditions is arrived, moment output voltage and can have the situation in loop
Lower generation electric current.Conventional manufacture of solar cells flow includes the processes such as making herbs into wool, diffusion, etching, silk-screen printing.Wherein screen printing
Brush belongs to porous printing, and it is collectively known as four big printing processes with flat stamping, convex print, gravure.The principle of porous printing is：Printing plate
(being produced in paper membrane version or the version base of other editions can be by the eyelet of ink) leads to ink in printing by certain pressure
The eyelet of via version is transferred on stock (paper, ceramics etc.), forms image or word.
Silk-screen printing is made up of top 5 factor, i.e., screen printing forme, scrape scraper plate, ink, print station and stock.Silk screen
Printing general principle is：Using the saturating ink of screen printing forme areas mesh, the general principle of non-graphic part mesh not strike through
Printed.Ink is poured on screen printing forme one end during printing, is applied with ink position of the scraper plate on screen printing forme is scraped
Certain pressure, while moved towards the screen printing forme other end, ink is expressed to by scraper plate from the mesh of areas on the move
On stock, trace set is made due to the viscous effect of ink within limits.Printing process middle scraper all the time with silk
Wire mark version and stock are in linear contact lay, and contact line is mobile with scraper plate and moves, due to keeping one between screen printing forme and stock
Fixed gap so that screen printing forme during printing produces the reaction force to scraper plate by the tension force of itself, this reaction
Power is referred to as screen resilience.Due to the effect of screen resilience, it is in only portable linear contact lay to make screen printing forme and stock, and screen printing forme its
It is partly disengaged position with stock, makes ink that rhegmagenesis occur with silk screen, ensure that printed dimensions precision and avoids rubbing
Dirty stock.Lifted after scraper plate scraped the whole space of a whole page, while screen printing forme also lifts, and as at the beginning of returning blade gently scrapes back ink
Beginning position.
Scraper is the instrument being expressed to metal paste on solar cell, and printing quality is had a major impact, but scraper
While metal paste is extruded, metal paste can flow to both sides, and gradually flow to outside the scope of scraper, cause dry pulp compared with
It is more, strong influence printing quality, turn into the common problem that current battery piece silk-screen printing faces.
Through retrieval, Chinese Patent Application No.：201310541582X, the applying date：On November 4th, 2013, invention and created name
For：A kind of scraper for silk-screen printing for being easy to adjust the returning charge wing, this application case disclose a kind of silk screen for being easy to adjust the returning charge wing
Printing scraper, including scraper body, the returning charge wing and adjusting means, adjusting means include support frame and adjusting bracket, support frame
Side is fixed on scraper body, and opposite side has a neck, is provided with regulating platform above neck, hole is provided with regulating platform, and set
There is corresponding adjusting nut, adjusting bracket is provided with projection corresponding with neck, and adjusting bracket can slide along neck, support frame and adjusting bracket
Fixed by fixed structure, the returning charge wing is fixed with adjusting bracket.Returning charge wing position can be adjusted for this application case, help to protect
Hinder printing quality, but this application case is unsatisfactory to the feed back collecting effect of slurry, it is still necessary to further Optimal improvements.
