Abstract
The invention relates to a novel scraping bar for silk screen printing. A scraping bar body is a rectangular long bar, and the surfaces of the positions of the end heads of both ends of the rectangular long bar are trimmed into surfaces with the shape of a circular arc. When the scraping bar for silk screen printing, which is disclosed by the invention, is used, a screen board is not easy to damage, the service life of the screen board can be greatly enhanced, the leakage of slurry is reduced, the production efficiency is enhanced, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of manufacture of solar cells instrument.
Background technology
At present, in solar cell is manufactured, after employing method for printing screen printing plated film, backplate, back surface field and the front electrode of silicon chip, want scraper, and the important component part of scraper is scraping article during printing.Scraping article is positioned at scraper bottom, is the part contacting with slurry and half tone, and its effect is exactly to promote slurry, and slurry is passed through from the visuals of half tone.The scraping article generally using now, its shape assumes diamond in shape, because of its edge sharper keen, easily cause contacted half tone to break, half tone is short service life, and loss is high, cost is higher, also easily causes various silver slurries required in screen printing process and the waste of aluminium paste, increases cost.
Summary of the invention
The present invention aims to provide a kind of Novel scraping bar for silk screen printing, is difficult for making half tone damaged during use, in the service life of improving half tone, enhances productivity, and reduces production costs.
A Novel scraping bar for silk screen printing, scraping article body is that rectangle is rectangular, the surfacing of the end, two ends that rectangle is rectangular is arcuate surface.
Four surfaces of scraping article body end are all trimmed to arcuate surface.
Described end is trimmed to smooth arcuate surface for to be trimmed to arcuate surface in the scope of termination 5-8mm.
The repairing amount that termination is trimmed to arcuate surface is 2.5-3.5mm.
The repairing amount that termination is trimmed to arcuate surface is 3mm.
Scraping bar for silk screen printing of the present invention, is difficult for making half tone damaged during use, in the service life that can greatly improve half tone, reduce spillage, enhances productivity, and reduces production costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 be Fig. 1 shown in the left side of structure look enlarged drawing.
The specific embodiment
As shown in Figure 1, 2, the profile of scraping article body 1 of the present invention is that cross section is the rectangular of rectangle, the surfacing of two ends that rectangle is rectangular is arcuate surface 2, can be arcuate surface 2 by one or two relative surfacings, also four surfaces all can be trimmed to arcuate surface 2, preferably four faces are all trimmed to arcuate surface.The length b that is trimmed to arcuate surface 2 on rectangular is the scope apart from termination 5-8mm, and the repairing amount a that end is trimmed to arc-shaped surface is 2.5-3.5mm, and preferably repairing amount a is 3mm.
Below two groups of contrast test results using existing scraping article and the present invention to carry out:
Test one: choose and be numbered 1 printing equipment on production line and use contrast
Table 1 is for being used the half tone situation of existing scraping article
Table 2 is for being used the half tone situation of scraping article of the present invention
Contrast table 1 and table 2 can find out that the present invention can make the utilization rate rising 2821pcs/ version of half tone, and every half tone can print 2821pcs more, improve 21.6%.And spillage ratio has reduced by 11.6%.
Test two: choose and be numbered 3 printing equipment on production line and use contrast
Table 3 is for being used the half tone situation of existing scraping article
Table 4 is for being used the half tone situation of scraping article of the present invention
Contrast table 3 and table 4 can find out, the present invention can make the utilization rate rising 1071pcs/ version of half tone, and every half tone can print 1071pcs more, improves 19.0%.And spillage ratio has reduced by 12.1%.
From above two groups of test results, can find out, the present invention can improve the service life of half tone significantly, increases operation rate, and reduces spillage, enhances productivity, and reduces production costs.
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of invention.
