Abstract

The invention discloses a nodeless screen printing plate based on a stainless steel plate and belongs to the technical field of printing equipment. The screen printing plate comprises a net frame and a carrier which is fixedly arranged in the net frame; one group of parallel main grid lines, one group of parallel secondary grid lines and one group of via holes for pulp to pass through are arranged at the center of the carrier; the main grid lines and the secondary grid lines are arranged vertically; a photo-sensitive adhesive film layer is arranged at the center of the carrier; and the key point is as follows: the carrier comprises the stainless steel plate as well as a frame-shaped polyester silk screen which is fixed on the surface of the stainless steel plate in an adhesion way; the main grid lines, the secondary grid lines and the via holes are arranged on the stainless steel plate positioned in the polyester silk screen to form a graphic area; a non-graphical area is arranged between the graphic area and the polyester silk screen; and the photo-sensitive adhesive film layer is arranged on the stainless steel plate in the polyester silk screen. The nodeless screen printing plate based on the stainless steel plate does not have the nodes, namely net nodes, of the traditional stainless steel silk screen, and has high surface evenness, small printing resistance, better printing property, higher strength and longer printing life.

Description

technical field

[0001] The invention belongs to the technical field of printing equipment and relates to a screen, in particular to a nodeless screen based on a stainless steel plate. Background technique

[0002] As the problem of environmental pollution becomes more and more serious, many countries begin to develop new green new energy sources to reduce environmental pollution, among which solar energy research occupies an important position. Solar cells can convert the sun's light energy into electrical energy, and this conversion will not cause any pollution to the environment. Therefore, solar cells, as one of the core technologies of solar energy research, have been rapidly developed. Screen printing is the last process in the entire battery sheet manufacturing process. By using the basic principle of the hollowed out part of the screen to penetrate the slurry and the non-hollowed part to be impermeable to the slurry, a layer of conductive paste is printed on the front...
