Abstract
The utility model relates to a circular arc-shaped printing scraper, which is provided with a first pressing bar, a second pressing bar and a scraping bar. The lower end of the first pressing bar is circular arc-shaped; the scraping bar is clamped and fixed between the first pressing bar and the second pressing bar; the upper end of the scraping bar is abutted to the lower end of the first pressing bar; and the curvature of the lower end of the scraping bar is the same as that of the lower end of the first pressing bar. Two ends of the scraping bar are respectively provided with a left extended portion and a right extended portion; the scraping bar is in a bent quadrangular shape; and the length of the scraping bar is 22cm. The edge of the scraper contacts with a screen plate more closely when in printing, pulp can be ensured effectively to be evenly covered on an integral printed pattern, and the printing quality problems of edge printing loss and the like can be eradicated effectively.
Description
Technical field
The present invention relates to the printing scraper technical field of silicon solar cell serigraphy, relate in particular to a kind of circular arc printing scraper.
Background technology
In screen printing process, the uniformity of slurry coating is extremely important, and the effect of slurry coating directly influences the quality of printed pattern.Slurry coating is to overstock slurry through scraping article, slurry leaked web plate and was imprinted on formation rule figure on the silicon chip, therefore, the effect that mutually combines of scraping article and web plate has directly determined the slurry coating effect, in order to print out high-quality figure, generally can on scraper, apply certain pressure, to guarantee that scraper contacts with the tight of web plate.In the prior art, the serigraphy scraping article generally all is straight surface, yet, there is such problem in this scraper: when pressing down scraper, because web plate can be to caving in into certain radian, so scraper edge pressure can be big, intermediate pressure is then smaller, pressure distribution on the whole scraper is very inhomogeneous, makes the scraper edge tight inadequately with contacting of web plate, influences printing quality.As in order to increase contacting of scraper and web plate, just needing increases the distance that scraper presses down, and can make web plate under excessive pressure and damage like this.Therefore, need a kind of scraper of new serigraphy, to overcome the problem that above-mentioned scraper exists.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of circular arc serigraphy scraper is provided, make its scraper edge when printing tightr with contacting of web plate, improve the serigraphy quality, reduce cost.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of circular arc printing scraper, have first press strip, second press strip and scraping article, the first press strip lower end is a circular arc, described scraping article is clipped between first press strip and second press strip and fixes, described scraping article upper end withstands on the first press strip lower end, and the bending curvature of scraping article lower end is identical with the bending curvature of the first press strip lower end.
Further, described scraping article two ends have left prolongation and right prolongation respectively, and described scraping article is four crooked prismatics, and described scraping article length is 22cm.
The beneficial effects of the utility model are: the lower end that scraping article of the present utility model contacts with silk screen is the circular arc with certain curvature, therefore, when serigraphy applied slurry, the scraping article edge of scraper was tightr with contacting of web plate, and the pressure distribution on the whole scraper is even.In addition, scraping article length is 22cm, has prolonged 10% than the scraping article of available technology adopting, has guaranteed that effectively slurry can evenly cover on the whole printed pattern, stops printing quality problems such as edge printing disappearance effectively.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. first press strip, 2. second press strip, 3. scraping article, 4. left prolongation, 5. right prolongation, 6. screw.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Circular arc printing scraper as shown in Figure 1, have first press strip 1, second press strip 2, scraping article 3, first press strip, 1 lower end is a circular arc, scraping article 3 is clipped between first press strip 1 and second press strip 2 and with screw 6 and fixes, scraping article 3 upper ends withstand on first press strip, 1 lower end, and the bending curvature of scraping article 3 lower ends is identical with the bending curvature of first press strip, 1 lower end.Scraping article 3 two ends have left prolongation 4 and right prolongation 5 respectively, and scraping article 3 is four crooked prismatics, and scraping article 3 length are 22cm.
The lower end that scraping article 3 contacts with silk screen has certain bending curvature, and therefore, when serigraphy applied slurry, scraping article 3 edges of scraper were tightr with contacting of web plate, and the pressure distribution on the whole scraper is even.In addition, scraping article 3 length are 22cm, have prolonged 10% than the scraping article of available technology adopting, guaranteed that effectively slurry can evenly cover on the whole printed pattern, stop printing quality problems such as edge printing disappearance effectively, improve the serigraphy quality, reduce cost.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
