Abstract
The invention discloses a kind of mask plate with combinative structure, by there is the flat screen of combinative structure and coating or overlay one or more layers photopolymer layer on flat screen and formed；Described flat screen is made up of non-graphic district and graph area, and graph area is different by 2 and the above number of mesh in the same direction and queueing discipline, variform grid array are constituted；This flat screen uses electrocasting method one-body molded, without braiding longitude and latitude node.Photopolymer on mask plate is specifying region to be set to hollow out form simultaneously, constitutes Printing Zone with this region mesh；The region of remaining non-hollow out form and described flat screen are bonded mask regions.According to mask plate of the present invention, the requirement to printing local of the day by day complicated product structure can be met, owing to described flat screen is one-body molded by electroforming, surface is smooth without node, can solve tradition mask plate plate face out-of-flatness, the problems such as printing blanking is uneven, and weaving is complicated, promote printing efficiency.
Description
Technical field
The present invention relates to electronic printing field, especially relate to a kind of electronic printing instrument.
Background technology
At present, the development of printing industry (including the printing of the flexible slurry such as ink, silver slurry) is more and more higher to the requirement of printing quality, and in printing-flow, the quality of printed medium (i.e. printing mask plate) is directly connected to final printing effect.The structure of traditional printing mask plate is to be formed at one layer of photopolymer of conventional screen surface-coated, wherein constitute the polyester webs that conventional screen is Weaving type or the metal gauze of mask plate, as shown in Figure 1, Weaving type silk screen is independent of one another owing to constituting the silk thread of its structure, therefore the longitude and latitude node (as shown in Fig. 2 (a) B1) of minim gap (as shown in B2 in Fig. 2 (b)) is left in the formation of intersection each other, on the one hand it forms the salient point that mask plate integral slab faces out, cause the out-of-flatness on surface, when making to print, blanking is uneven, cause final products height dimension unbalanced, grid line as thin in solar panels height is uneven, simultaneously, due to the weaving used, the glacing flatness making silk thread is difficult to be completely secured, when being prepared as mask plate, the final products cross-sectional edge formed is in irregular shape, it is easily formed wavy；On the other hand, owing to using weaving, also making complex process, operation is difficult to, inefficient；3rd, owing to using weaving, make the change of flat screen partial structurtes relatively difficult to achieve, the most whole flat screen wire side hole mesh number keeps consistent, it is difficult to change, when to final products when locally lying in particular/special requirement and requiring that flat screen changes at the mesh number of relevant position, the most traditional weaving is difficult to.
What the present invention proposed is made, by electroforming is one-body molded, the mask plate that the flat screen with combinative structure without Weaving type longitude and latitude node is constituted, and preferably resolves problem above, improves finished product yield simultaneously, improve production efficiency.
Summary of the invention
In view of this, need to overcome at least one in drawbacks described above of the prior art.The invention provides a kind of mask plate with combinative structure, including there is the flat screen of combinative structure and coating or overlay one or more layers photopolymer layer on described flat screen, there is described in composition described in the mask plate of combinative structure the flat screen employing one-body molded making of electroforming having combinative structure and being made up of the graphics field that multiple mesh numbers of grid in the same direction are different, the Weaving type longitude and latitude node formed on conventional screen without tradition weaving；The described mask plate with combinative structure can improve the shape of printing finished product, improves yields；Simplify tradition weaving, raising efficiency；Disclosure satisfy that the requirement to printing local of the day by day complicated product structure simultaneously.
Meanwhile, described in there is the mask plate of combinative structure the grid of different meshes can be set in the described flat screen with combinative structure specifies region, the particular/special requirement utilizing mask plate to print can be met.When mask plate for silicon solar cell anelectrode printing as described in use prints: the thin grid line of electrode requires that the depth-width ratio of printing is big, thus it requires the thin grid line Printing Zone of mask plate has preferable analytic ability and the most lower slurry amount, plane can be relatively easy to control the thickness of mask plate without node type silk screen, relatively thin mask plate has more preferable analytic ability, and bigger mesh mesh number (i.e. the quantity of grid lines reduces) is set herein and consequently reduces the obstacle of silver slurry blanking, it is ensured that there is at thin grid line Printing Zone the most lower slurry amount；Electrode main grid line requires relatively low, and the gauge of printing is without relatively big, and on the contrary, relatively thin electrode main grid line can save silver slurry, minimizing cost that can be bigger in large-scale production.
According to the present invention, it is provided that a kind of mask plate with combinative structure, including: there is the flat screen of combinative structure and on the described flat screen with combinative structure, coat or overlay one or more layers photopolymer layer.
