Abstract
The utility model discloses a printing scraper for a screen printing machine, which comprises a scraper body (2) and a scraping strip (1), wherein the scraping strip (1) is arranged on a scraper slot (4) at the bottom of the body (2). The printing scraper for the screen printing machine is characterized in that: both ends of the scraping strip (1) are respectively provided with an arc-shaped rubber shielding plate (5). In the utility model, the arc-shaped rubber shielding plates are arranged and correspond to an ink-reclaiming knife when the printing scraper is used, so that slurry is effectively controlled within a printing area, the working procedures of shoveling the slurry squeezed to both edges back to the middle of a screen by production personnel are reduced, the utilization ratio of the slurry is increased, the generation of the dry slurry is reduced, and the printing effect is improved; and the workload of the personnel is also reduced.
Description
Technical field
The utility model relates to a kind of printing scraper, relates in particular to a kind of screen printing machine printing scraper of using in the silicon solar cell screen printing process.
Background technology
Among the system technical process of silicon solar cell, the two-face printing positive and negative electrode of the silicon chip of requirement after forming pn knot and plated film and back of the body field, this realizes by serigraphy.
Serigraphy is having the masterplate of image or pattern attached to printing on the silk screen.When below stock is placed directly in the silk screen that has masterplate, screen printing ink or coating pass the mesh in the middle of the silk screen under the extruding of scraper, be printed onto on the stock.Masterplate on the silk screen is sealed a part of silk screen aperture and is made pigment can not pass silk screen, and has only image section to pass, and therefore has only the image position that trace is arranged on stock.In other words, serigraphy is actually and utilizes ink penetration to cross that forme prints.
In the middle of the process of producing, when using existing scraper toward the silicon chip surface printed patterns, printing-ink is the both sides that slurry can be pressed to half tone by scraper, if do not handle the slurry that these are pressed against both sides for a long time, these slurries will solidify in air gradually, these slurries of having done can make printing undesirable condition occur, undesirable condition such as complete, long-pending point of short-term, seal can occur such as printing silicon chip front gate line; On the other hand, these dry finish also can stop up half tone, reduce the service life of half tone; Simultaneously, the generation of these dry finish has also reduced the utilization rate of slurry, has increased production cost.
The utility model content
The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, provides a kind of result of use good screen printing machine printing scraper.
Technical scheme: screen printing machine printing scraper described in the utility model, comprise the scraper body, be arranged on the scraping article on the described body bottom scraper groove, the two ends of described scraping article are provided with arc rubber shutter; Described scraping article is fixed on the described scraper groove by trip bolt.
Preferably, the thickness of described arc rubber shutter equates with the thickness of described body.
The bottom of described arc rubber shutter flushes with the bottom of described scraping article.
The opening degree of described arc rubber shutter is within the returning blade opening degree that is used, and in printing process, arc rubber shutter is corresponding with returning blade, effectively slurry is controlled in the printing zone like this.Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, the utility model is by being provided with arc rubber shutter, corresponding during use with returning blade, effectively slurry is controlled in the printing zone, reduce producers and shovel back the middle operation of half tone, reduce the employee work amount with the slurry that scoop will press to both sides; 2, the utility model improves solar cell silk-screen three roads back of the body silver, back of the body aluminium, and the utilization rate of positive silver reduces production costs; 3, the utility model reduces the possibility that dry finish produces, reduce because of the bad generation of the printing that dry finish caused, as: the broken string during the printing grid line, long-pending point, empty seal, the printing issues such as disappearance that produce during the printed back electric field; 4, the utility model reduces because of dry finish stops up the half tone decline in service life that the half tone hole causes, and reduces the manufacture of solar cells cost.

The specific embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
A kind of screen printing machine printing scraper comprises scraper body 2, is arranged on the scraping article 1 on the described body 2 bottom scraper grooves 4, and the two ends of described scraping article 1 are provided with arc rubber shutter 5; Scraping article 1 length is 180mm, and width is 9.5mm, highly is 9.5mm; The length of camber rubber shutter 5 is 35mm, by trip bolt 3 scraping article that has camber rubber is fixed on the scraper groove 4; The thickness of described arc rubber shutter 5 equates with the thickness of described body 2; The bottom of described arc rubber shutter 5 flushes with the bottom of described scraping article 1; The corner is a fillet under arc rubber shutter 5 both ends, so can not scratch half tone when printing; The opening degree of described arc rubber shutter 5 is within returning blade 6 opening degrees that are used.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
