Embodiment 1

[0035] A planar screen with adjustable openings, including a planar screen, characterized in that the screen is a honeycomb structure formed by interconnecting polygonal arrays; the screen area of ​​the planar screen is divided into a mask area and a pattern Area, by changing the array unit structure of the local area, adjust the local opening ratio of the planar screen.

[0036] The screen is a honeycomb structure formed by interconnecting polygonal arrays; the screen area of ​​the planar screen is divided into a mask area and a graphic area, and at the junction of the mask area and the graphic area, the bridging unit of the graphic area and the graphic area The array unit structure in the mask area is connected in a ratio of 1:2.

[0037] like figure 1 As shown in the enlarged schematic diagram of part I, that is, as figure 2 As shown, it is a partial structure of screen that can be used to make solar cell sheet printing screen.

[0038] figure 2 Among them, 21 corresp...

Embodiment 2

[0041] A planar screen with adjustable openings, the screen is a honeycomb structure composed of polygonal arrays connected to each other; the screen area of ​​the planar screen is divided into a mask area and a pattern area, by adjusting the size of the array unit To adjust the local opening ratio of the flat screen.

[0042] The screen is a honeycomb structure formed by interconnecting polygonal arrays; the screen area of ​​the planar screen is divided into a mask area and a graphic area, and at the junction of the mask area and the graphic area, the bridging unit of the graphic area and the graphic area The array unit structure in the mask area is connected in a ratio of 1:5.

[0043] like image 3 As shown, it shows a partial structure of a screen that can be used to make a solar cell sheet printing screen. image 3 Among them, the wire diameter size of the array unit on the main gate line 31 is different from the wire diameter size of other regions (fine grid 32 , mask ...

Embodiment 3

[0046] A kind of planar silk screen with adjustable aperture, the structure is the same as embodiment 1, a layer of photosensitive polymer is coated on the screen, the schematic diagram is as follows Figure 4 As shown, 41 is a main grid line, and 42 is a thin grid line. Figure 5 Corresponding to the enlarged schematic diagram of part II on it, which is related to figure 1 Corresponding to part I of the planar screen shown, 51 is the main grid line structure, 52 is the fine grid line structure, and 53 is the mask area structure.

Abstract

The invention relates to a trepanning-adjustable flat silk screen. The trepanning-adjustable flat silk screen mainly solves the problems that a silk screen is not stable in structure and low in mechanical strength in an existing precision printing technology. The trepanning-adjustable flat silk screen comprises a flat silk screen body, and is characterized in that the flat silk screen body is of a faveolate structure formed by mutual connection between a polygonal array or a circular array; the silk screen area of the flat silk screen body is divided into a masking area and a plot area. An array unit structure of a local area is changed, the size of an array unit is adjusted, or the two methods are combined, so that the local trepanning rate of the flat silk screen is adjusted, the problem is well solved, and therefore the trepanning-adjustable flat silk screen and the screen printing plate comprising the same can be widely used in industrial production of precision printing.

Description

[0001] technical field [0002] The present invention relates to a flat screen with adjustable openings and a printing screen composed of the same. Background technique [0003] With the rapid development of the economy, the consumption of energy is increasing, and the storage of non-renewable resources such as coal and oil is decreasing day by day, which prompts people to pay attention to new energy sources (such as nuclear energy, solar energy, wind energy, biomass energy, geothermal energy, ocean energy, hydrogen energy, etc.) Among them, as the source of many energies on the earth, solar energy occupies an important position in the research of new energy sources, and solar cells are a core representative of solar energy applications. [0004] Improving the conversion efficiency of solar cells is a major goal of solar cell research at present. In addition to the selection of cell substrate materials and the improvement of the substrate manufacturing process, the selectio...
