Abstract

The invention discloses a knotless screen printing plate based on positioning marks and a manufacturing process of the knotless screen printing plate. The knotless screen printing plate comprises first screen cloth and second screen cloth which are arranged in sequence, wherein a screen frame is arranged on the periphery of the second screen cloth; and a line printing area is arranged on the first screen cloth, and the plurality of positioning marks are attached to the second screen cloth. According to the knotless screen printing plate based on the positioning marks and the manufacturing process of the knotless screen printing plate, use is convenient, the positioning marks are arranged on the screen printing plate, the position of a gauze is measured on image mapping / AL detection equipment with the positioning marks as coordinates, a pattern needing to be printed is arranged according to the position of the gauze, then the graph is directly input into laser equipment / CTS plate making equipment, the initial position of the printed pattern on the screen printing plate is found by positioning and aligning the marks on the screen printing plate, and then the pattern to be printed is prepared by adopting laser or CTS exposure. The plate making process is greatly shortened, the plate making yield, efficiency and quality stability of the knotless screen printing plate are improved, and the process is suitable for mass production of the knotless screen printing plate.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a knotless screen plate based on a positioning mark and a manufacturing process thereof. Background technique [0002] Knot-free screens can achieve finer line printing because there is no net knot in the ink penetrating part of the line, and are adopted by more and more users in solar cell grid printing. The production process of the traditional knotless screen is as follows: firstly, after the screen is stretched, the internal stress is released by standing still; then, according to the predetermined spacing between the grid lines, the position of the mesh is measured by surveying and mapping / AL equipment, and the position of the grid lines is adjusted. Position and straightness, arrange the grid lines to the position between adjacent mesh yarns, and then output photopainting film according to the position and shape of the rearranged grid lines; then the measured screen pla...
