Description

Coated printing screen

This creation is about the structure of a printing screen, especially a coating printing screen that includes a metal film layer.

In the conventional technology, the printing screen is alternately woven by warp and weft. In the conventional non-mesh screen structure, the yarn removal method can be used to make it, and the yarn removal method can be made by laser scanning. Yarn way. However, in the production process of the printing screen, a certain tension is used to stretch the mesh to perform the yarn removal action, so that the stress is easily released during the removal of the mesh, which causes the original yarn removal position to shift, causing the removal of the yarn. The position of the pattern after the yarn is not accurate, which in turn reduces the process yield.

[Problems to be solved by the new model] It can be known from the above-mentioned prior art that there are problems of positional deviation and inaccurate alignment in the process of removing the mesh, which in turn causes a low production yield or an increase in process costs. Therefore, it is necessary to provide a brand-new screen structure so that the alignment problem of precise alignment can be solved during the yarn removing process, and at the same time, the yield rate can be improved without increasing the production cost.

[Technical means to solve the problem] A coated printing screen includes a screen frame; and a composite screen including a squeegee surface and a printing surface, and the composite screen further includes: a first material screen fixed on the screen frame; and a second material screen , Including a plurality of warp threads and a plurality of weft threads, the second material net is coupled to the first material net, the first material net and the second material net are combined to form a composite edge, and the second material net The upper layer includes at least one pattern area; a metal film layer, formed on the warp threads and the weft threads outside the at least one pattern region on the second material net, the warp threads and the weft threads through the metal The film layer is covered and fixed; and a polymer material layer is arranged on one side of the printing surface of the second material net including the metal film layer, and the polymer material layer includes at least one printed pattern, the at least A printing pattern is arranged in the at least one graphic area.

Preferably, in the second material net, the warp threads and the weft threads covered by the metal film layer are arranged in a mutually staggered form, and the at least one pattern area does not include the The warp threads are equal, and the weft threads are arranged in the form of at least one weft thread at every interval.

Preferably, in the second material net, the warp threads and the weft threads covered by the metal film layer are arranged in a mutually staggered form, and the at least one pattern area does not include the The wefts are equal, and the warps are arranged in the form of at least one warp at every interval.

Preferably, the thickness of the metal film layer is 2-8 μm.

Preferably, the area of the at least one pattern area is 2-10 times the area of the at least one printed pattern.

[New Effect] It can be seen from the above content that this creation provides a printing screen including a metal film layer. The metal film layer will cover the entire warp and the entire weft in a specific area on the printing screen, and will also cover the warp and weft at the same time. Wrapped at the cross node. In this way, the warp and weft threads can be fixed to each other by the metal film layer, and when the thread yarn is to be removed in the printing screen, the remaining thread yarn will be fixed by the metal film layer, and the thread yarn will not be broken due to the removal. After falling, the yarn starts to shift.

(First embodiment) The following is a more detailed description of the implementation of this creation in conjunction with the drawings and component symbols, so that those who are familiar with the art can implement it after studying this manual.
