The utility model discloses a following technical scheme realizes:
a screen printing plate for improving broken grid virtual printing of battery piece printing E L comprises a longitudinal main grid line and a transverse fine grid line, wherein a first grid line and a second grid line are sequentially arranged on the fine grid line from the intersection of the main grid line and the fine grid line to the direction of two ends of the fine grid line, the width of the first grid line and the width of the second grid line are gradually reduced from the intersection of the main grid line and the fine grid line to the direction of two ends of the fine grid line, the width of the first grid line is larger than that of the second grid line, and the width of the second grid line is larger than that of the fine grid line.
Furthermore, when the device is used, the width of the auxiliary grid line is increased at the intersection position of the main grid and the auxiliary grid through the structure that the widths of the two sections of the first grid line and the second grid line are gradually changed, the deposition amount of the slurry at the intersection position is increased, the contact area of the slurry and the surface of the silicon wafer is increased, and therefore the problem of the battery fragment grid is solved.
In the patent that has now, add fusiformis arch through the both sides about the thin grid line at the intersection of main grid line and thin grid line to increase the width of the thin grid line of intersection, when using, this structure compares with the first grid line and the second grid line of this structure, and the thick liquids deposit volume of the increase main grid line that this structure can be better and thin grid line intersection increases the area of contact on thick liquids and silicon chip surface, the broken bars of avoiding that can be better.
Through setting up the grid line of two sections different width of first grid line and second grid line, can further improve the smooth and easy degree of printing, compare with the arch of the gradual change of one section width of current setting, the disconnected bars of reduction that can be better.
Compared with the prior patent, the net plate structure of the structure has the advantages that the broken grid virtual printing of the structure is reduced by 0.2 percent, and the problem of broken grid is solved.
And the width that first grid line and second grid line of this device are close to main grid line and thin grid line intersection is 0.1mm and 0.034mm respectively. The length of the first grid line is smaller than that of the second grid line. The length of the first grid line is 0.6mm, and the length of the second grid line is 2.5 mm.
The setting can further reduce the rework rate, improve the qualification rate of products and save the cost. The optimal effect can be achieved under the length and the width, and the problem of broken grid virtual printing is effectively avoided.
Secondly, a plurality of hollow grooves are formed in the main grid line of the structure. The hollow groove is located between two adjacent thin grid lines.
The hollow-out grooves are formed in the main grid lines, so that slurry can be effectively saved when the novel grid-type solar cell is used, and long-term use is facilitated.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
1. the utility model relates to a improve half tone of battery piece printing E L broken grid virtual seal, this device can the effectual thick liquids deposit volume that increases main grid line and thin grid line junction, avoids the broken grid, more is convenient for long-term use;
2. the utility model relates to a screen printing plate for improving broken grid virtual printing of battery piece printing E L, which further reduces rework rate, improves product qualification rate and saves cost;
3. the utility model relates to an improve half tone of battery piece printing E L disconnected bars virtual seal, this device simple structure, convenient to operate and use, this structure is more stable when printing simultaneously.
