Utility model content

Technical problem to be solved in the utility model is：In order to overcome thin grid line bar in prior art to overlap with warp or Slurry in solar battery sheet prints is led to pile up uneven deficiency through longitude and latitude node, this utility model provides one kind too Sun can cell piece no net be knotted version.

This utility model solves its technical problem technical scheme to be taken：A kind of solar battery sheet no net is knotted Version, including the warp being spacedly distributed and parallel, described warp and parallel intersect vertically and form multiple grids, described warp and latitude The intersection point of line forms node, and the thin grid line bar bearing of trend of described solar battery sheet is parallel with the bearing of trend of described warp, And described thin grid line bar is unequal interval distribution, the thin grid line bar at least being overlapped with warp is staggered a segment distance to the left or to the right, And the error of the distance between adjacent two thin grid line bars is in the allowed band of error.Make net by finely tuning the position of thin grid line bar The thin grid line bar of version all occupy in the middle of the grid of silk screen warp, all keeps a segment distance with the silk screen warp on both sides.

Preferably, the position being overlapped with thin grid line bar with first warp is started, and makes to be located at through distance between centers of tracks and thin grid line bar Thin grid lines location on spacing common multiple staggers a segment distance to the left or to the right.

Specifically, described half tone is drawn in the net using 90 ° of directions.

Operational approach, first silk screen are drawn in the net with 90 ° of directions, then pass through measuring apparatus, by each thin grid line bar adjustment At nearest neutral gear near script position, using minimizing adjustment, realize the mesh in warp neutral area for all thin grid line bars 's.

The beneficial effects of the utility model are：A kind of solar battery sheet no net that this utility model provides is knotted version, its The thin grid line bar of half tone all occupy in the middle of the grid of silk screen warp, all keeps a segment distance with the silk screen warp on both sides, passes through The unequal interval distribution of thin grid line bar is avoided and the overlapping so that the only horizontal parallel of half tone thin grid line bar produced is worn of silk screen Cross, do not have warp to pass through.Thus so that the accumulation form of slurry is more uniform in the printing of solar battery sheet, height is more Height, finally makes the conversion efficiency of product higher.
