A kind of large format composite halftone of saving cost
Technical field
The present invention relates to the printed element fields such as solar battery sheet, high-accuracy electronic devices and components, particularly relate to a kind of large format composite halftone of saving cost.
Background technology
The silk-screen half tone is the important component part of screen painting, directly affects the quality of printing quality.Along with the high speed development of the industries such as solar energy, microelectronics, touch-screen, also more and more higher to the requirement of accurate half tone application.This has just impelled in half tone manufacturing process, to the also raising in the lump of requirement of manufacture craft and making material.In accurate half tone is made, metal material or compound high fiber as printing carrier, be the core of half tone cost of manufacture as materials such as stainless steel cloth, stainless steel steel disc, nickel alloy electroforming net, tungsten steel alloy silk screen, V-screen silk screen, MASA silk screens, the consumption of effectively saving metal material can directly affect the cost that half tone is made.
In the printing process of solar cell, the use of printing screen plate has a significant impact final printing quality, printing locating hole on printing screen plate has guaranteed the accuracy in the printing process, but the printing screen plate that tradition is used all adopts stainless steel material, and the part composite halftone can not reach best saving consumption in the application of metal material, therefore increase the cost of printing screen plate, thereby improved the price of solar cell, be unfavorable for the extensive use of solar cell.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of accurate positioning and saves the large format composite halftone of cost.
for solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of large format composite halftone of saving cost is provided, comprise the first silk screen, the second silk screen, screen frame, locating hole and Printing Zone, described the second silk screen is connected with described screen frame, the Back Word type structure that described the second silk screen is hollow also is connected with described the first silk screen, the middle vacancy of described the second silk screen is covered by described the first silk screen, described locating hole is two and lays respectively on described second silk screen of described the first silk screen parallel edges both sides, described Printing Zone is positioned on described the first silk screen, described the first silk screen adopts the first metal material or composite fibre, described the second silk screen adopts polyester material or the second metal material.
In a preferred embodiment of the present invention, described two locating holes are positioned on described second silk screen of both sides, two long limits of described the first silk screen, and the long limit of the line of described two locating holes and described the first silk screen is perpendicular, described two anchor points be centered by the central point of described the first silk screen, symmetrical, the distance between described two locating holes is 24-25 centimetre.
In a preferred embodiment of the present invention, described two locating holes are positioned on described second silk screen of two minor face both sides of described the first silk screen, and the minor face of the line of described two locating holes and described the first silk screen is perpendicular, and the distance between described two locating holes is 40-52 centimetre.
In a preferred embodiment of the present invention, described the first metal material comprises stainless steel cloth, stainless steel steel disc, nickel electroforming net, tungsten steel alloy silk screen.
In a preferred embodiment of the present invention, the length of described the first silk screen is 10-60 centimetre, and width is 10-50 centimetre.
In a preferred embodiment of the present invention, the length of described the first silk screen is 38 centimetres, and width is 22 centimetres.
the invention has the beneficial effects as follows: the large format composite halftone of saving cost of the present invention, dwindle the first silk screen area, partly substitute the first silk screen material therefor in the conventional composite net with cheap material, described locating hole is positioned on the second silk screen, the first silk screen material therefor usable floor area diminishes, saved the use of material, greatly reduce the solar battery sheet printing, the cost of the high-accuracy screen paintings of industry such as microelectronics, improve the screen painting resilience by the area that strengthens the second silk screen simultaneously, make printing accuracy and printing life-span improve than the conventional composite half tone.

Fig. 2 is the structural representation that the present invention saves another preferred embodiment of large format composite halftone of cost;
In accompanying drawing, the mark of each parts is as follows: 1, the first silk screen, the 2, second silk screen, 3, screen frame, 4, locating hole, 5, Printing Zone, 6, the screen frame screwed hole, the 7, second locating hole, the 8, the 3rd silk screen.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
Print simultaneously at present the large format printing equipment of two silicon chips for half tone of solar battery sheet, mainly contain the Microtek of Japan and the JRT of Germany, according to distinct device, have the different printing locate mode, mainly be divided into located lateral and longitudinal register.
Embodiment one:
See also Fig. 1, the invention provides a kind of large format composite halftone of saving cost, comprise the first silk screen 1, the second silk screen 2, screen frame 3, locating hole 4, Printing Zone 5 and screen frame screwed hole 6, can be used for the longitudinal register printing equipment.Described the second silk screen 2 is connected with described screen frame 3, the Back Word type structure that described the second silk screen 2 is hollow is also sticking mutually by PUR, instant glue or UV glue with described the first silk screen 1, and the middle vacancy of described the second silk screen 2 is covered by described the first silk screen 1. and described Printing Zone 5 is positioned on described the first silk screen 1.The length of described the first silk screen is 38 centimetres, and width is 22 centimetres.
Described locating hole 4 is two and is positioned on described second silk screen 2 of both sides, two long limits of described the first silk screen 1, and the long limit of the line of described two locating holes 4 and described the first silk screen 1 is perpendicular, described two anchor points 4 be centered by the central point of described the first silk screen 1, symmetrical.Distance between described two locating holes 4 is 24-25 centimetre according to the different set of equipment.Described screen frame screwed hole 6 has four, lays respectively on the horizontal long limit of described screen frame 3, plays fixedly screen frame effect when printing.
Described the first silk screen 1 adopts the first metal material or compound high fiber, and described the second silk screen 2 adopts polyester material or the second metal material.Described the first metal material can adopt multiple material, for example stainless steel cloth, stainless steel steel disc, nickel electroforming net, tungsten steel alloy silk screen, and described compound high fiber can be V-screen silk screen or MASA silk screen etc.Described the second metal material also can adopt multiple material, for example adopts the stainless steel material of polyester material or thick line footpath, low mesh number, and it is 200 order polyester nets or 150 order stainless steel cloths that the present embodiment adopts better order number.Described the second silk screen 2 material used material more used than described the first silk screen 1 is cheap.
Embodiment two:
