Abstract
The invention discloses a silk screen of a combined structure. The silk screen of the combined structure comprises a non-graphical area and a graphic area. The graphic area is composed of two or more graphic regions different in mesh number in a same direction, and preferably, the number of the graphic regions is 2,3,4,5 and 6. Each graphic region is formed by regular array of meshes in different shapes and structures. The silk screen of the combined structure is integrally made by means of electroforming, and is free of woven warp-weft nodes. According to the silk screen of the combined structure, special printing requirements on local regions in the printing process of the printing industry can be met; meanwhile, since the silk screen of the combined structure is integrally made by means of electroforming, the silk screen of the combined structure is smooth in surface and free of woven nodes, the problems that a traditional mask plate with warp and weft nodes is non-smooth in surface, uneven in discharging during printing and easy to damage during wiping and cleaning are solved, a complex weaving technology of the traditional mask plate is avoided, and efficiency is improved.
Description
Technical field
The present invention relates to the electronic printing field, especially relate to a kind of electronic printing instrument.
Background technology
At present, the development of printing industry (comprising the printing of the flexible slurries such as printing ink, silver slurry) is more and more higher to the requirement of printing quality, and in printing-flow, the quality of printed medium (being the mask to print plate) is directly connected to final printing effect.The structure of traditional printing mask plate is to apply one deck photopolymer on the silk screen surface to form, polyester webs or woven wire that the silk screen that wherein forms mask plate is Weaving type, as shown in Figure 1, the Weaving type silk screen is because the silk thread that forms its structure is independent of one another, therefore form in intersection each other the longitude and latitude node (as shown in Fig. 2 (a) B1) that leaves minim gap (as shown in B2 in Fig. 2 (b)), it forms the mask plate integral slab towards outer salient point on the one hand, cause surperficial out-of-flatness, blanking inequality while making printing, cause the final products height dimension unbalanced, grid line height as thin as solar panels is uneven, simultaneously, due to the weaving adopted, make the glacing flatness of silk thread be difficult to guarantee fully, also caused final products cross-sectional edge out-of-shape, easily form wavy, on the other hand, owing to adopting weaving, also make complex process, operation is difficult for, and efficiency is lower, the 3rd, owing to adopting weaving, make the more difficult variation that realizes partial structurtes of an order net, be that whole silk order net wire side hole order number is consistent, be difficult to change, while when final products are existed to specific (special) requirements in part, requiring the order number of an order net in relevant position to change, traditional weaving is difficult to realize.
The silk order net with combining structure without Weaving type longitude and latitude node by the one-body molded making of electroforming that the present invention proposes, preferably resolve above problem, improved the finished product yield simultaneously, promoted production efficiency.
Summary of the invention
In view of this, need to overcome at least one in above-mentioned defect of the prior art.The invention provides a kind of silk order net with combining structure, the described silk order net with combining structure adopts the one-body molded making of electroforming, by a plurality of on equidirectional the different graphics field of order number form, can improve the shape of printing finished product, improve yields; Simplify traditional weaving, raising efficiency; Can meet day by day complicated product structure to printing local requirement simultaneously.
Simultaneously, the described silk order net with combining structure can arrange the mesh of different meshes in appointed area, can meet the specific (special) requirements that utilizes the mask plate printing.As while being printed for the mask plate of silicon solar cell positive electrode printing as described in adopting: the thin grid line of electrode requires the depth-width ratio of printing large, thereby the thin grid line Printing Zone that requires mask plate has preferably analytic ability and descends the slurry amount preferably, plane can mask plate more easy to control without the node type silk screen thickness, thinner mask plate has better analytic ability, and the obstacle that larger mesh order number (quantity that is grid lines reduces) has reduced silver-colored slurry blanking accordingly is set herein, can guarantee that place, thin grid line Printing Zone has to descend the slurry amount preferably; It is relatively low that electrode main grid line requires, and the gauge of printing is without larger, and on the contrary, thinner electrode main grid line can saving silver paste, Cost reduction that can be larger in large-scale production.
According to the present invention, a kind of silk order net with combining structure provided, comprising: non-graph area and graph area; Described graph area by 2 and above on equidirectional the order number different and formed by the graphics field of regularly arranged grid array; The shape of the described grid of described grid array can be the combination of polygon, circle or its shape; The grid wire diameter that forms the described grid array that forms described graphics field can be identical, also can be different.
