The on-line scrubbing device is a device for removing leaked slurry on the back of the screen printing plate in the printing process to reduce or eliminate nodal points. The device comprises a scrubbing head and a bracket, wherein the scrubbing head comprises a perforated scraper and an organic solvent trough. The device can be arranged on a printing platform or at other proper position in a printing machine, and the screen printing plate for the cell is scrubbed on line by adjusting the height of the device. Through the device, poor factors such as the nodal points on the surface of the solar cell can be greatly reduced, manpower can also be reduced, the screen printing yield is improved, damage of human factors to the screen printing plate is reduced, and harm of the organic slurry to the human body is reduced. The industrial competitiveness of an enterprise is improved when the cost of the enterprise is saved.
Description
Technical field
The present invention relates to the screen printing technique field of crystal-silicon solar cell, be specifically related to the online swab of a kind of solar cell screen printing screens.
Background technology
Photovoltaic industry competition now is fierce day by day, and except the conversion efficiency that improves solar cell, reducing cost also is the road that must have of Business survival and development.An important step during printing process is made as the conventional crystal silicon solar cell becomes the bottleneck of photovoltaic production capacity day by day, thereby has restricted the reduction of cost; And the outward appearance of product also causes client's concern day by day.In printing process, because the outward appearance " node " that half tone slurry seepage causes needs to suspend board and carries out the manual wipping half tone, so not only reduced production capacity, and consumed certain manpower in order to reduce.According to rough calculation, the time-out board carried out the half tone wiping in about 10～20 minutes, and each wiping half tone needs the wire mark time of 5 battery sheets at least, and wiping half tone reduction production capacity reaches as high as more than 2% like this; And also increased by 0.5 people's workload, increased the use amount of running stores such as non-dust cloth alcohol greatly; Artificial unstability of cleaning also can influence the service life of half tone.
Summary of the invention
The object of the invention is exactly the online swab of a kind of solar cell screen printing screens that provides to the defective of above-mentioned existence; This device can improve the production capacity of printing process greatly, reduces cost of labor, reduces the use amount of running stores; Can also reduce the injury that artificial unstability of cleaning causes half tone; Cause the half tone reduction in service life, the contacting of organic ink and human body when reducing artificial the scouring makes the injury reduction of printing process to human body.
The online swab technical scheme of a kind of solar cell serigraphy provided by the invention does, the online swab of a kind of silk-screen printing plate for solar cells comprises scrub head and support, and scrub head comprises scraper with holes and organic solvent groove.
Said scraper with holes is a strip; Have together or together with upper knife edge; Hole perpendicular to outer surface is arranged on the scraper, and scraper with holes selects for use soft polyurethane rubber of quality or Viton to process, and scraper with holes bottom is installed in the organic solvent groove; And can be up and down along organic solvent groove inwall, blade surface with holes is with flannelette.
Described organic solvent groove inner bottom part has a sideboard, and sideboard can be up and down along organic solvent groove inwall.In the said organic solvent groove, place a cavernous body between sideboard and the scraper with holes as buffer body.The organic solvent of splendid attire is alcohol or other alcohol organic solvent in the organic solvent groove, can be according to the automatic supply organic solvent of the pressure of flannelette and printing screen plate.
Support comprises that a group or more support spring and pillar and thereof support cavity, and the organic solvent trench bottom is connected with support spring and pillar thereof, and there is screw the pillar lower end, through fixed by nut.
Between the upper end of supporting cavity and organic solvent groove, do not install or one or more springs are installed, play buffering and supporting role.
Inner surface or outer surface at the support chamber body sidewall evenly are provided with a group or more clamp button of the spring, and every group is positioned on the plane, and wherein one group is two or more, and clamp button of the spring is " 7 " font.
Said online swab is fixedly mounted on the printing platform of silicon chip printing machine, and the blade of scraper with holes becomes an angle of 90 degrees with the rotation direction of printing platform on horizontal plane.
Said online swab is installed also can be installed in other any suitable location on the non-printing platform in the silicon chip printing board.
The present invention can pass through the position of the nut adjusting device of pillar lower end, also can be through supporting the position and the duty of the clamp button of the spring fixture on the cavity.
Can print 1～1000 battery sheet and once clean according to actual conditions,, can push the support cavity, and fix, reduce the position of supporting cavity through clamp button of the spring if obsolete the time.In time change flannelette according to concrete operating position decision, add organic solvent.
Beneficial effect of the present invention is: the online swab of this solar cell serigraphy; Comprise scrub head and support, scrub head comprises scraper with holes and organic solvent groove, and the hole perpendicular to outer surface is arranged on the scraper; Can guarantee that organic solvent oozes out; Blade surface is with flannelette, and the scraper quality is soft, can not damage printing screen plate during use;
Organic solvent groove inner bottom part has a sideboard; Sideboard can be up and down along organic solvent groove inwall; In the said organic solvent groove, place a cavernous body between sideboard and the scraper with holes as buffer body, can be according to the automatic supply organic solvent of the pressure of flannelette and printing screen plate;
Support comprises that a group or more support spring and pillar and thereof support cavity, and the organic solvent trench bottom is connected with support spring, and there is screw the pillar lower end, through fixed by nut; Between the upper end of supporting cavity and organic solvent groove, do not install or one or more springs are installed, play buffering and supporting role.
Inner surface or outer surface at the support chamber body sidewall are provided with two or more clamp button of the spring.Can online scouring half tone, through the position of clamp button of the spring and nut adjusting device, it is more convenient that device is used.
The highest production capacity that can improve the printing board of this device is practiced thrift human cost more than 2%, reduces the use amount of running stores, reduces artificial unstability of cleaning to the injury that half tone causes, and causes the half tone reduction in service life.The contacting of organic ink and human body when significantly reducing artificial the scouring makes the injury reduction of printing process to human body.
