Abstract
The invention discloses the antiseized returning blade of a kind of screen printing machine, be made up of link and cutter body, described cutter body has metal blade, described cutter body has polytetrafluoroethylene (PTFE) top layer, the thickness on described polytetrafluoroethylene (PTFE) top layer is 0.05-0.5 millimeter, because returning blade of the present invention has polytetrafluoroethylene (PTFE) top layer, therefore returning blade is made to have excellent greasy property, returning blade surface has not viscosity, when returning ink, full-bodied slurry can be easy to fall in half tone from returning blade, and then improve back black effect, returning blade of the present invention coordinates the use of highly viscous slurry, printing depth-width ratio is had improve significantly, the photoelectric transformation efficiency of battery also can promote to some extent, and the metal blade of returning blade has Passivation Treatment layer or baking vanish layer, the Corrosion Protection of returning blade can be promoted, improve the service life of returning blade.
Description
Technical field
The invention belongs to screen printing apparatus field, be specifically related to a kind of screen printing machine returning blade.
Background technology
In the processing procedure of solar cell, by serigraphy, electrocondution slurry is printed onto on silicon chip.Serigraphy five is wanted greatly: half tone, frictioning, slurry, print station and stock.Serigraphy general principle: utilize half tone areas mesh strike through, the general principle of non-graphic part mesh not strike through is printed.On half tone, add slurry during printing, frictioning applies certain pressure to half tone, moves towards the half tone other end simultaneously.Slurry is expressed on stock in movement from mesh, and due to viscous effect, set within limits.Owing to keeping certain gap between half tone and stock, half tone produces the screen resilience to frictioning by the tension force of self, make half tone and stock only in portable linear contact lay, and other parts and stock is disengaged position, slurry and silk screen generation rhegmagenesis, ensure that printed dimensions precision.Frictioning lifted after scraping the whole space of a whole page, and half tone also lifts simultaneously, and by returning blade, slurry is gently scraped back initial position, completes a print stroke.At present, for improving the conversion efficiency of solar cell, the full-bodied electrocondution slurry of the many uses of manufacturer prints, when using existing returning blade to carry out back ink, because the viscosity of slurry is easily attached on returning blade comparatively greatly, feed back is caused to tail off, cause back ink uneven, and then have influence on printing effect, easily there are disconnected grid, time serious, there will be empty print phenomenon.Therefore just need artificial perching knife that the slurry on returning blade is returned shovel in the middle of half tone at set intervals, operation will have influence on the production of sliver so frequently, affects operating efficiency.
Summary of the invention
In order to solve the problem, the invention provides the antiseized returning blade of a kind of screen printing machine, the antiseized returning blade of this screen printing machine can effectively avoid existing common returning blade to cause printing bad problem because slurry when highly viscous slurry returns ink sticks on returning blade.
The present invention in order to the technical scheme solving its technical problem and adopt is:
The antiseized returning blade of a kind of screen printing machine, be made up of link and cutter body, described cutter body has metal blade, and described cutter body has polytetrafluoroethylene (PTFE) top layer, and the thickness on described polytetrafluoroethylene (PTFE) top layer is 0.05-0.5 millimeter.
The present invention in order to the further technical scheme solving its technical problem and adopt is:
Preferably, the thickness on described polytetrafluoroethylene (PTFE) top layer is 0.1 millimeter.
Preferably, described metal blade surface has Passivation Treatment layer, and described Passivation Treatment layer trypsin method has described polytetrafluoroethylene (PTFE) top layer, and the thickness of described Passivation Treatment layer is 0.01-0.05 millimeter, preferably, the thickness of described Passivation Treatment layer is 0.03 millimeter.
It is preferred that described metal blade surface has baking vanish layer, and described baking vanish layer trypsin method has described polytetrafluoroethylene (PTFE) top layer, and the thickness of described baking vanish layer is 0.2-0.8 millimeter, and preferably, the thickness of described baking vanish layer is 0.3 millimeter.
It is preferred that described link has polytetrafluoroethylene (PTFE) top layer, the thickness on the polytetrafluoroethylene (PTFE) top layer of link is 0.05-0.5 millimeter, and preferably, the thickness on the polytetrafluoroethylene (PTFE) top layer of described link is 0.1 millimeter.
Say further, described cutter body is made up of one section of flat segments and two arc block edges, and described flat segments is positioned at the centre of described cutter body and its upper end is fixedly connected with described link, and described arc block edge is integrally connected to the two ends, left and right of described flat segments.
The invention has the beneficial effects as follows: the antiseized returning blade of screen printing machine of the present invention has polytetrafluoroethylene (PTFE) top layer due to it, therefore returning blade is made to have excellent greasy property, returning blade surface has not viscosity, when returning ink, full-bodied slurry can be easy to fall in half tone from returning blade, and then improve back black effect, returning blade of the present invention coordinates the use of highly viscous slurry, printing depth-width ratio is had improve significantly, the photoelectric transformation efficiency of battery also can promote to some extent, and the metal blade of returning blade has Passivation Treatment layer or baking vanish layer, the Corrosion Protection of returning blade can be promoted, improve the service life of returning blade.
