Description
Technical field
The utility model relates to photovoltaic industry battery production technology, relates in particular to solar energy crystal silicon cell silk-screen printing technique.
Background technology
In recent years, with the in short supply and people of the energy its own existence environment requirement is improved constantly, regenerative resource has obtained paying close attention to widely.Wherein, solar energy becomes the emphasis of new energy development as the regenerative resource of cleaning.2000-2010, global photovoltaic industry fast development, wherein crystal silicon cell occupies the market leading position always.For the crystal silicon cell preparation section, mainly comprise technical process such as cleaning and texturing, diffusion system knot, peripheral etching, coated with antireflection layer, electrode making, wherein the making of electrode is to be the indispensable operation of electric energy with conversion of solar energy.Crystal silicon battery is produced in the line at present, and the making of electrode is accomplished through oversintering after mainly utilizing electrocondution slurry to form required electrode pattern through serigraphy again.
At present existing silk-screen printing device structure mainly is made up of print engine head, printing scraper (frictioning is inlayed at general edge), feed back cutter and printing screen plate etc.When electrode printed, the feed back cutter rose, and printing scraper descends and acts on half tone silk screen face and travel forward with certain squeegee pressure, and the squeezing action of slurry through scraper sees through the silk screen face and be printed on and form electrode pattern on the battery sheet; During feed back, printing scraper rises, silk screen face pop into position, and the feed back cutter descends and acts on half tone silk screen face and motion backward with suitable pressure simultaneously, thereby accomplishes stone to treat printing next time.In this kind printing equipment structure, printing scraper is in the zone between printing scraper and the feed back cutter with the parallel placement of feed back cutter, electrocondution slurry; On the other hand, for the elastic deformation ability that adapts to half tone silk screen face with guarantee printed patterns precisely, the design of silk screen face width degree will be far longer than the width of printing zone.Like this, just caused in printing process, slurry is understood flowing to " non-Printing Zone " of nature, thereby breaks away from the control range of scraper and feed back cutter.With the carrying out of printing, this part slurry can be stuck in " non-Printing Zone " always, causes the volatilization of organic solvent in the slurry, thereby causes local mummification.When the mummification slurry is sneaked in the printing slurry again, cause network blocking easily, problems such as disconnected grid; In addition, the slurry of stagnation and the slurry viscosity of motion, flowability, thixotropy are different, also can cause printing bad.Produce the method for head it off on the line at present: with perching knife it is scraped the Printing Zone through the operative employee, cause the waste of slurry but the edge still has remnants, and in the process of shovel, can touch half tone, can influence printing quality to a certain extent; If when stopping print engine head shovel slurry, cause the reduction of production efficiency for a moment to the Printing Zone, the 2nd, when restarting print engine head, just the printing stability of the battery sheet of printing also can be affected.
Summary of the invention
The purpose of the utility model is in order to solve in the electrode screen printing process of solar energy crystal silicon cell; Slurry flows to the problem of the non-printing zone of printing scraper and feed back cutter both sides of the edge, and a kind of printing equipment structure that prevents slurry mummification waste and guarantee printing quality is provided.
The structure of the utility model comprises: half tone framework, silk screen, baffle plate, scraper, feed back cutter, knife rest, undercutter, scraping article, baffle-panels, baffle plate installing rack, baffle plate framework, baffle plate drop handle, baffle plate angle fine tuning structure, baffle plate bolt, the control of undercutter elasticity, baffle plate mounting groove.
On printing screen plate, two baffle arrangements are installed near the printing scraper both sides of edges; Wherein baffle arrangement mainly is made up of baffle-panels, baffle plate framework and installing rack; Between baffle-panels and the printing screen face inclination angle can be set, baffle-panels and baffle plate framework are provided with 0-5 ° of angle vernier device structure; The bottom of baffle-panels contacts with silk screen face detachable or coheres through flexible material; Baffle-panels and feed back cutter, the seamless contact in the edge of scraper and undercutter, and can contact slip; Print engine head drives scraper and contacts slip with baffle-panels with the feed back cutter, and slurry is moved in the scope that both sides baffle-panels, scraper and feed back cutter surround, and realizes that slurry is not to two side flow; When baffle plate is connected with framework with half tone framework coupling part, can be shifted to regulate the spacing of two baffle plates; Top is provided with draw ring, is convenient to the replacing of baffle plate; Undercutter is connected through guide frame with scraper; And can slide relatively, the moving range of undercutter wherein is provided with elastic device through positioning control; Elasticity adjusting is to guarantee reducing the pressure of undercutter to silk screen to greatest extent under the situation that slurry does not flow through.
The beneficial effect that the utility model reached: the baffle arrangement simplicity of design, and also very little to the deformation behavior influence of half tone silk screen face, thus the accurate of printed patterns guaranteed.Prevent effectively that on the other hand slurry from flowing to non-printing zone, guarantee that slurry has the flowability of homogeneous, viscosity and thixotropy, avoid local mummification of slurry and waste, thereby improve electrode printing efficiency and printing quality.
