Description

A kind of silk screen of latitude and longitude different meshes

Technical field

The utility model relates to a kind of silk screens, and in particular to a kind of silk screen of latitude and longitude different meshes.

Background technique

Conventional screen be the smooth stainless steel silk thread or composition metal silk thread in surface by direction of warp and weft weaving and It is interlaced evenly distributed at warp and weft when, braiding, form the uniform reticular structure that is open；After the completion of grenadine braiding, meeting It is cut according to different plate-making demands, the composite halftone for forming some tension be bonded with polyester screen frame after cutting.Composite web Version is after cleaning and degreasing, and coating photoresists carry out printing down, and then development obtains figure.Due to the silk screen table of conventional method braiding Face is smooth, and photoresists and wire binding force are weak, will appear photoresists in printing process and the bad phenomenons such as falls off, influencing halftone makes Use the service life.

Since silk screen is alternately woven by latitude and longitude, net knot will form in warp weft junction.Traditional halftone production Printing sawtooth is formed in order to avoid printing down figure is fallen on silk screen in the process, silk screen and screen frame can be generally kept at an angle （Such as 22.5 °, 30 °, 45 °）, so that net knot is occupied certain grid line area, with the reduction of printing grid line width, net It ties the ratio occupied to increase, then silver paste can be hindered to bite on silicon wafer, make to print grid line generation breakpoint, influence turning for crystal silicon battery Change efficiency.

In order to allow printing lines just to fall in a mesh spacing, avoids net knot from falling on grid line, then need silk screen Latitude and longitude and screen frame frame keeping parallelism are vertical, and we term it the positioning of zero degree silk screen.However the opening face of conventional screen Product is too small, and when directly carrying out zero degree positioning using these silk screens, printing lines equally have probability to fall in grenadine net to tie.

Summary of the invention

To solve the above problems, the purpose of the utility model is to provide a kind of silk screen of latitude and longitude different meshes, silk used Line has carried out roughening treatment before braiding, and surface is provided with the salient point or concave point for increasing roughness, and the silk screen after braiding is being coated with Photoresists and silk screen Adhesion enhancement in process, photoresists are not easy to fall off in printing process, and be able to extend halftone uses the longevity Life.

The informing system of sample treatment plant is to realize above-mentioned technical purpose and the technique effect, the utility model passes through Following technical scheme is realized：

A kind of silk screen of latitude and longitude different meshes, including the warp arranged in warp direction and in the latitude of weft direction arrangement Line, the warp and the weft are silk thread；

The warp is evenly distributed, warp described in every two silk threads and Cheng Yigen or

Several silk threads be arranged in one group described in warp, the overall width of warp described in every group, which is less than, to be printed between thin grid Spacing, interval guarantees grid line described in falling in two groups between warp between warp described in every two groups.

Further, the silk thread is tinsel or composition metal silk thread.

Further, the wire surface is provided with the salient point or concave point for increasing roughness.

Further, warp direction mesh number is -500 mesh of 200 mesh.

Further, weft direction mesh number is -800 mesh of 300 mesh.

The utility model has the beneficial effects that：

Silk thread used in the utility model has carried out roughening treatment before braiding, surface be provided with the salient point for increasing roughness or Concave point, silk screen after braiding photoresists and silk screen Adhesion enhancement in painting process, photoresists are not easy to take off in printing process It falls, is able to extend the service life of halftone.

The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail It describes in detail bright as after.Specific embodiment of the present utility model is shown in detail by following embodiment and its attached drawing.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the utility model；

Fig. 2 is another structural schematic diagram of the utility model.

Figure label explanation：

1, warp, 2, weft.

Specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.

A kind of silk screen of latitude and longitude different meshes, including the warp 1 arranged in warp direction and in weft direction arrangement Weft 2, the warp 1 and the weft 2 are silk thread；

Shown in Figure 1, the warp 1 is evenly distributed, warp 1 described in every two silk threads and Cheng Yigen or

It is shown in Figure 2, several silk threads be arranged in one group described in warp 1, the overall width of warp 1 described in every group is less than Print the spacing between thin grid, interval guarantees grid line described in falling in two groups between warp 1 between warp 1 described in every two groups.

Further, the silk thread is tinsel or composition metal silk thread.

Further, the silk thread has carried out roughening treatment before braiding, surface be provided with the salient point for increasing roughness or Concave point, coarsing processing method include chemical attack or physical impact.

Further, warp direction mesh number is -500 mesh of 200 mesh, and weft direction mesh number is -800 mesh of 300 mesh.

For the utility model there are two types of weaving manner, one of which is to adjust the silk thread quantity of warp and weft in braiding, The aperture openings of density not etc. are formed in warp, weft direction, so that it is formed in the grenadine of warp and weft direction different meshes, Just there is bigger distance between warp in this way, guarantee that printing lines will not be fallen on warp, ink is by uniformly when printing, printing Pattern line is more straight；Another kind is to adjust warp spacing in braiding, have bigger spacing in warp direction in this way, together Shi Qiangdu also gets a promotion.

The operating procedure of another weaving manner is：

Step 1）Roughening treatment first is carried out to the silk thread for weaving silk screen before screen knitting, increases the thick of wire surface Rugosity；

Step 2）Warp is arranged to required mesh number in warp direction according to the design needs；

Step 3）The weft of mesh number needed for being arranged according to the design needs in weft direction；

Step 4）Weaving removable two adjacent silk threads when warp, to together, i.e., every two silk threads are passed through at one side by side Line, to increase intensity such as Fig. 1 of warp direction.

Step 5）According to printing needs, the braiding of warp separated regions, such as Fig. 2, on warp direction, several silk threads are according to height Mesh number arrangement, forms one group of warp, and the width of every group of warp is less than the spacing between thin grid, is spaced between every two groups of warps larger Distance guarantees that grid line is fallen between two groups of warps.

The foregoing is merely the preferred embodiments of utility model, are not intended to limit the utility model, for ability For the technical staff in domain, various modifications and changes may be made to the present invention.It is all the spirit and principles of the utility model it Interior, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
