Abstract
The invention discloses a scraper used for the silk-screen printing of a solar cell, comprising a scraper body, wherein the lower end of the scraper body is provided with a scraping strip. The scraper is characterized in that two sides of the scraper body are respectively provided with an auxiliary scraper blade; an included angle between the auxiliary scraper blade and the front part of the scraper body is 110-130 degrees; the lower end of the auxiliary scraper blade is provided with the auxiliary scraping strip; and the lower plane of the auxiliary scraping strip is leveled with the lower plane of the scraping strip. When the scraper is used in the silk-screen printing process of the solar cell, a printing zone becomes a relatively sealed environment, and two auxiliary scraper blades can better control slurry within a printing graph, thereby greatly improving the quality and the effect of the silk-screening printing; in addition, slurry can be prevented from generating; and printing fragments have small possibility of being generated in the printing process. According to the scraper, the slurry amount is saved, and the frequency for an operator to shovel slurry is lowered.
Description
Technical field
The present invention relates to solar-photovoltaic technology field, the scraper of using while being specifically related to solar battery sheet serigraphy.
Background technology
In solar battery sheet screen printing process, require the slurry of printing zone between half tone figure, the size of printed pattern scope and cell piece matches.In printing process, if the amount that slurry adds is many, the slurry mummification speed outside printed pattern can be accelerated, and causes the waste of slurry, and the slurry of mummification all causes certain harmful effect to printing effect and half tone life-span.
The structure of the current equipment for solar battery sheet serigraphy is: comprise a print station, on print station, be provided with half tone, the top of half tone is provided with scraper and returning blade, described scraper and returning blade are by print head control, shown in Figure 1, scraper used comprises cutter hub 1 at present, is provided with scraping article 2 in the lower end of cutter hub 1.When printing, print head control scraper and returning blade are pasting half tone and are moving back and forth, the pressure pattern extruding slurry infiltrate screen cloth using by scraper, thus realize printing.
The major defect that the scraper of said structure exists is: in printing process, if slurry use amount is few, can affect the quality of solar battery sheet serigraphy; If slurry use amount is many, can cause again the slurry mummification outside half tone figure, the slurry of mummification not only can reduce the printing quality of cell piece, also can cause the generation of cell piece fragment in printing process.
Summary of the invention
