The invention discloses a solar cell screen printing plate having a paste amount limiting function. The solar cell screen printing plate comprises an outer framework and a silk screen arranged on the outer framework, wherein the silk screen is provided with a printing surface which is in contact with a printing stock and an ink scraping surface which is in contact with a scraper; the printing surface is communicated with the ink scraping surface through silk screen holes; a pattern area is formed at the aggregating position of the silk screen holes; a non-pattern area is formed on the periphery of the pattern area; a current-limiting framework is arranged on the periphery of the pattern area of the ink-scraping surface; a sealing ring is arranged between the current-limiting framework and the silk screen ink-scraping surface; the current-limiting framework is detachably connected with the outer framework. According to the solar cell screen printing plate, the current-limiting framework is additionally arranged outside the pattern area of the screen printing plate, so that the problem of difficulty in controlling the adding amount of paste in the screen printing plate is solved, the screen printing plate is protected, and the pulp is saved.
Description
Technical field
The present invention relates to solar battery sheet serigraphy device, especially relate to a kind of solar battery sheet half tone with slurry current limliting.
Background technology
In the silkscreen process of solar battery sheet, mainly use plastic cement scraping article at stainless steel cloth printed thereon, make half tone produce strike through after deformation, thus reach object slurry being printed onto cell piece surface.
If in half tone, printing slurry is on the low side in printing process, after causing printing, cell piece area is not printed onto slurry, the namely scarce print of cell piece, lack the cell piece of print then because printing problem of appearance is classified as abnormal sheet or degradation sheet, so consider from the angle reducing degradation sheet, enough slurries should be added in printing half tone as far as possible.The half tone used in this printing process is generally stainless steel cloth, and this type of stainless steel cloth steel wire wire diameter used is generally less than 35 microns, and the stainless steel cloth structural strength of the wire establishment of little wire diameter is poor, easy damaged.The membership that adds of a large amount of slurry makes the stainless steel wire of stainless steel cloth produce mechanical damage thus distortion, adds slurry less, scrap to prevent half tone because of damage so consider try one's best in half tone from the angle of protection printing stainless steel cloth.
As can be seen from above 2; diametrically opposite demand is there is between printing quality and half tone life-span; in order to avoid there is conflict; it is repeatedly add on a small quantity that general company advocates the principle that employee adds printing slurry, but in normal productive process, still often there will be the printing accident caused because of the unreachable position of employee.
China Patent Publication No.: CN202640954U, in the patent document in publication date on January 2nd, 2013, disclose a kind of screen printing screens, the silk screen comprising screen frame and stretch tight on described screen frame, described silk screen is provided with and the printing surface of substrate contacts and the wiping face that contacts with scraper plate, described printing surface is communicated with by silk screen hole with wiping face, the described silk screen hole place of gathering forms pattern area, described pattern area periphery forms non-pattern area, also comprise adhesive tape, described tape-stripping is on the described non-pattern area in described wiping face.Continuous pressing device for stereo-pattern on the non-pattern area in silk screen wiping face, effectively can alleviate the squeezing action power of non-pattern area upper scraping plate to photosensitive material on silk screen, the stripping delaying photosensitive material on non-pattern area comes off, thus extends service life, reduces production cost.Are all sprawled regions of slurry in the screen frame of this type of screen printing screens, in use procedure, easily cause the unmanageable problem of above-mentioned said slurry addition.
Summary of the invention
The present invention is to solve the unmanageable problem of slurry addition in half tone, provides a kind of solar battery sheet half tone with slurry current limliting.
To achieve these goals, the present invention is by the following technical solutions:
A kind of solar battery sheet half tone with slurry current limliting of the present invention, comprise outside framework and be arranged on the silk screen on outside framework, described silk screen is provided with and the printing surface of substrate contacts and the wiping face that contacts with scraper plate, described printing surface is communicated with by silk screen hole with wiping face, the described silk screen hole place of gathering forms pattern area, described pattern area periphery forms non-pattern area, the limit, pattern area four in described wiping face is provided with current limliting framework, be provided with sealing ring between described current limliting framework and silk screen wiping face, current limliting framework is detachably connected on outside framework.
The spread range of printing slurry is limited in certain area at the pattern area current limliting framework in wiping face by the present invention, thus makes a small amount of slurry just can reach the object of normal printing.Its benefit: one for preventing half tone because adding slurry too much deformation damage; Two control for convenience of employee the amount adding slurry; Three for saving slurry use amount.Always there is gap between current limliting framework and the silk screen space of a whole page, so be provided with sealing ring, preventing slurry from spilling from gap when printing.Sealing ring is soft simultaneously, is clipped between current limliting framework and silk screen, silk screen can be protected to prevent scratch.
As preferably, the top of described sealing ring is provided with groove, and current limliting framework is connected in described groove.This structure settles current limliting framework more firm.
As preferably, described sealing ring outer ring is provided with and extends limit.The bottom area of expansion sealing ring, place firm, and for not affect printing work, sealing ring will shrink as far as possible under making its duty in pattern area, toward the expansion of non-pattern area.
As preferably, described current limliting framework four limit is respectively provided with a connecting rod, and connecting rod end is provided with snap ring, and outside framework four limit is respectively provided with an open tubular column, and snap ring is socketed on open tubular column, and open tubular column top is provided with movable latch.Easy installation and removal.
As preferably, described current limliting framework is square, and the height of current limliting framework is 20mm.
As preferably, described current limliting framework is aluminum alloy frame.Aluminium alloy is comparatively light, alleviates half tone load-bearing.
The present invention has following beneficial effect: the additional upper flow framework in half tone pattern area, solves the unmanageable problem of slurry addition in half tone, protects half tone, saved slurry.
