Abstract
The utility model discloses a scraper used for a solar cell screen process press. The scraper comprises a knife rest and a knife body, wherein the knife body comprises a knife body frame which is made of a rigid material and a scraping and smearing edge region which is made of a soft material; the cross section of the knife body is rectangular; the scraping and smearing edge region can be repeatedly used by polishing; the knife body frame is fixed to the bottom end of the knife rest by a clamping block; material clustering stop blocks are respectively arranged on two ends of the knife rest; the bottoms of the material clustering stop blocks are flush with the bottom of the scraping and smearing edge region. According to the scraper used for the solar cell screen process press, the knife body adopts a split design of the knife body frame and the scraping and smearing edge region; when the scraper is used for a long time and a scraping and smearing edge is worn, the knife body is taken down, the scraping and smearing edge region is subjected to polishing processing, and after the scraping and smearing edge which is unsmooth due to abrasion is repaired, the scraper can be used again; meanwhile, the two material clustering stop blocks are also arranged on the bottom end of the knife rest, and a sizing agent is prevented from shifting.
Description
Technical field
The utility model relates to a kind of screen printing machine scraper, the scraper adopting when silver-colored aluminium paste being struck off on the screen process press adopting while specifically solar cell being carried out to electrode printing.
Background technology
The step such as crystal silicon solar cell sheet manufacture craft generally includes making herbs into wool, diffusion, etching, depositing antireflection film, print electrode, serigraphy is being attached to the process of printing on silk screen with the masterplate of image or pattern, in solar cell manufacturing process, adopt the mode in printing three roads respectively back of the body silver, back of the body aluminium and positive silver are printed on the back side and the front of cell piece, thereby reach the effect of silver slurry collected current.In printing process, need there is a special scraper that the silver-colored aluminium paste on silk screen is scraped and smeared, slurry is evenly pressed in the hole of the image template on silk screen, and be printed on cell piece, it is foursquare soft elongated cutter hub and a knife rest that existing scraper generally includes a cross section, described cutter hub is clamped by the chuck on knife rest, utilize of cutter hub to scrape to smear rib slurry is scraped and smeared, scraper in use for some time, scrape and smear rib certain wearing and tearing can occur, cause scraper to scrape the inhomogeneous of slurries while smearing, need to change in time cutter hub, that is to say, cutter hub is to need to discard after disposable use, cause the increase of production cost, simultaneously, in the time of operation, slurry on silk screen is easily smeared rib two ends from scraping run material, both wasted material, also easily slurry is bonded on the frame of silk screen.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide one and can reuse, to improve cutter hub utilization rate, and the solar cell silk screen printing machine scraper reducing production costs.
For achieving the above object, the technical solution adopted in the utility model is: a kind of solar cell silk screen printing machine scraper, comprise a knife rest and a cutter hub, described cutter hub comprises that cutter hub frame and soft material that a hard material forms form Gua Moleng district, the cross section of described cutter hub is rectangle, described Gua Moleng district can repeatedly be used by polishing, and described cutter hub frame is fixed on the bottom of knife rest by clamp.
Two ends of described knife rest have respectively a poly-material block, and the bottom in the Yu Guamoleng district, bottom of described poly-material block is equal.
Described two poly-material blocks are less than the distance away from the junction of knife rest with the distances of the junctions of knife rest, poly-ly expect that blocks are splayed configuration and control for two.
Adopt solar cell silk screen printing machine scraper of the present utility model, by cutter hub is adopted to cutter hub frame He Guamoleng district split-type design, after scraper uses a period of time to scrape to smear rib and wear and tear, cutter hub can be taken off, then processing is polished in Dui Guamoleng district, repair because of uneven the scraping of wearing and tearing and smear after rib, can reuse again; Meanwhile, be also provided with two poly-material blocks in knife rest bottom, prevent the race material of slurry.
Brief description of the drawings
Fig. 1 is side structure schematic diagram of the present utility model;
Fig. 2 is Facad structure schematic diagram of the present utility model.
In figure: 1-knife rest, 2-cutter hub, 3-clamp, 4-Gua Moleng district, 5-cutter hub frame, the poly-material of 6-block, 7-installing hole.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of solar cell silk screen printing machine scraper, comprise a knife rest 1 and a cutter hub 2, on described knife rest 1, there is an installing hole 7, by installing hole 7, knife rest 1 is fixed on the power set on screen process press, do moving back and forth back and forth to drive knife rest 1, its innovative point is mainly that cutter hub frame 5 and soft material that described cutter hub 2 comprises that a hard material forms form Gua Moleng district 4, the cross section of described cutter hub 2 is rectangle, described Gua Moleng district 4 can repeatedly be used by polishing, described cutter hub frame 5 is fixed on the bottom of knife rest 1 by clamp 3.When use, utilize of 4 bottoms, Gua Moleng district to scrape to smear rib the slurries on silk screen are scraped and smeared, use after a period of time, cutter hub 2 is taken off from knife rest 1, and the bottom surface in Dui Guamoleng district 4 polish repair after, again load onto knife rest 1, can reuse again.
Solar cell silk screen printing machine described in the utility model is that with another innovative point of scraper two ends of described knife rest 1 have respectively a poly-material block 6, and the bottom in the Yu Guamoleng district, bottom 4 of described poly-material block 6 is equal.Like this, when knife rest 1 translation, of 4 bottoms, Gua Moleng district scrapes and smears rib the slurries on silk screen are scraped while smearing, the slurries that run material from cutter hub 2 two ends are blocked by two poly-material blocks 6, and move ahead together with knife rest 1, both prevent the race material of slurries, also have certain effect to stablizing printing quality simultaneously.
Conventionally, as shown in Figure 2, described two poly-material blocks 6 are less than the distance away from the junction of knife rest 1 with the distances of the junctions of knife rest 1, and two poly-material blocks 6 are splayed configuration and control.
