Abstract
The utility model discloses a printing scraping knife comprising a main printing knife body. The left side and the right side of the main printing knife body are bent towards the front surface of the main printing knife body for forming circular arc flood wings; the bottom of the main printing knife body is provided with a printing knife scraping strip; the bottom of the back side of the main printing knife body is provided with a descending step surface which is fixed with an auxiliary printing knife body; a printing knife scraping strip installing groove is formed between the main printing knife body and the auxiliary printing knife body; and the printing knife scraping strip is installed in the printing knife scraping strip installing groove. The two sides of the main printing knife body are each provided with one flood wing similar to an ox horn, so that the printing scraping knife can prevent lateral leakage and piling of paste, reduce coverage area of the paste, save the operation of frequent collection of the paste by workers, reduce labor intensity of the workers and synchronously improve monitoring of printing quality.
Description
Technical field
The utility model relates to solar energy crystal silicon cell screen printing technique, is specifically related to the back electrode of solar energy crystal silicon cell and the scraper that the positive electrode printshop is used.
Background technology
At present, the screen process press of the AMAT company of extensive use in industry, former factory printing scraper project organization is adopted as right-angle type printing cutter.Mode of printing is: Squeegee and flood (first feed back after the printing), printing scraper is done the compressional movement of up and down, front and back at equipment after installing the printing scraping article.The printing process in due to compressional movement, the slurry of part is expressed to place, scraper both sides and piles up, need the continual use perching knife of personnel that the slurry of piling up is shoveled back screen painting regional, the collection process of perching knife will enlarge slurry and cause the waste of part slurry in the area coverage of half tone.Fail timely collection as piled stock and will cause printing zone without slurry, printing quality problem and the waste of part slurry that piled stock becomes dry and causes.
The utility model content
Technical problem to be solved in the utility model just is to provide a kind of printing scraper, solves the problem that in printing process, the slurry side leakage is piled up, and avoids the artificial frequent slurry of collecting, and reduces personnel labor intensity.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: printing scraper, comprise printing cutter main body, it is characterized in that: the described printing cutter main body left and right sides all is bent to form the feed back wing of circular arc to printing cutter main body front, described printing cutter bottom part body is equipped with printing cutter scraping article.
Preferably, bottom, the described printing cutter main body back side is provided with a cascaded surface that descends, fix a printing cutter time body on this cascaded surface, form a printing cutter scraping article mounting groove between printing cutter main body and printing cutter time body, described printing cutter scraping article is installed in printing cutter scraping article mounting groove.
Preferably, described printing cutter scraping article is square column, and described printing cutter scraping article mounting groove is the square groove of unfilled corner, and one jiao of unfilled corner from printing cutter scraping article mounting groove of printing cutter scraping article is stretched out.
Preferably, be integrated by screw fastening between described printing cutter main body and printing cutter time body.
Preferably, described screw is the M4*20 soket head cap screw.
Preferably, the length 〉=180mm of described printing cutter main body.
Preferably, the angle of described feed back wing circular arc is 50 degree.
The utility model respectively designs a feed back wing that exactly likes ox horn in the both sides of printing cutter, and its beneficial effect is:
(1) solve the overlay area area that the slurry side leakage is piled up, reduced slurry.
(2) avoid the artificial frequent slurry of collecting, reduce personnel labor intensity, can synchronously strengthen the monitoring to printing quality.
(3) along with the minimizing to the slurry operation, can reduce the slurry contamination probability.Slow down silver slurry evaporation rate, and reduce the waste of silver slurry.
(4) along with the minimizing to the operation of silver slurry, further reduce the probability of slurry contamination.
(5) the half tone lifting surface area reduces, and reduces the half tone wearing and tearing, improves half tone service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the utility model scraper back side structural representation;
Fig. 2 is printing cutter main body and printing cutter time body fit structure schematic diagram.
The specific embodiment
As depicted in figs. 1 and 2, embodiment for the utility model printing scraper, it comprises printing cutter main body 1, and described printing cutter main body 1 left and right sides all is bent to form the feed back wing 11 of circular arc to printing cutter main body front, and described printing cutter bottom part body is equipped with printing cutter scraping article 13.Bottom, the described printing cutter main body back side is provided with a cascaded surface that descends, fix a printing cutter time body 10 on this cascaded surface, form a printing cutter scraping article mounting groove 12 between printing cutter main body and printing cutter time body, described printing cutter scraping article 13 is installed in printing cutter scraping article mounting groove 12.Described printing cutter scraping article 13 is square column, and described printing cutter scraping article mounting groove 12 is the square groove of unfilled corner, and one jiao of unfilled corner from printing cutter scraping article mounting groove of printing cutter scraping article 13 is stretched out.
Described printing cutter main body 1 and printing cutter time 10 of bodies are integrated by screw fastening.Described screw is the M4*20 soket head cap screw.Length 〉=the 180mm of described printing cutter main body 1.
For realizing printing scraper feed back function, respectively design a feed back wing that exactly likes ox horn in the both sides of printing scraper.The feed back wing is circular arc type, and the angle of circular arc is 50 degree.Right angle due to former printing scraper has changed arc chord angle into.The printing scraper of arc chord angle, with returning blade every Ullage from becoming arc chord angle every sky by parallel every space-variant.Former parallel every Ullage by 10mm, be arc chord angle after change every Ullage from being 1.26mm, every Ullage from greatly reducing.The arc chord angle of printing scraper and the arc chord angle of returning blade block before and after just forming, and the process of slurry in the front and back extruding can be remained between printing scraper and returning blade like this motion that moves in circles.Thereby realize the feed back function of printing scraper, solve former right angle printing scraper the slurry problem of piling up, the corresponding relevant issues that cause because of accumulation that just solved of the accumulation problem that has solved slurry.
