Intelligent silk screen nesting board-making technology

Abstract

The invention discloses an intelligent silk screen nesting board-making technology. By virtue of the technology, high correction precision is achieved, waste of manpower and material resources is highly lowered, and working efficiency is further improved. Two kinds of correction modes are adopted: 1, a coordinate value of an offset printing pattern is obtained and corrected, the corrected value istransmitted to a host, and a corrected coordinate value is worked out by calculation of the host; 2, the nesting correction information is recorded automatically, and all nesting correction information generates a nesting correction data table; manual correction is performed according to the nesting correction data table, and then board making is performed; and through a board making mode of a combination of DMD laser direct board making and large-area explosion of an LED module, quick edge sealing can be realized through the LED module, so that the board making effect of the silk printed effect is not influenced, the load of the laser imaging system is lowered, and service life of a DMD optical micro-mirror array is also prolonged.

Description

technical field [0001] The invention relates to the technical field of screen printing plate-making, and more specifically relates to an intelligent screen-positioning plate-making process. Background technique [0002] Screen printing is referred to as silk screen printing. During printing, the ink is transferred to the substrate through the holes of the stencil through a certain pressure to form images or characters. The current traditional screen plate-making technology is to use film to make plates through drying machines. The specific solution is to use offset printing to print the processed image on the film through a multi-mode laser, and the film is soaked and cleaned in liquid medicine to reveal the image, similar to a film camera, the film with pictures is black, and the film without pictures is white, and then the The film with the image is pasted on the screen plate brushed with screen glue according to the requirements of the production position, and exposed fo...

Problems solved by technology

[0004] First, the pollution is serious: and the film used for CTP is seriously polluted, and the repeated waste rate is too high

Some cities have begun to ban the use of film technology, because film contains too much harmful heavy metals, which is very serious for environmental pollution and will directly endanger the health of users who have been in contact with it for a long time

[0005] Second, the plate-making efficiency is low: the traditional screen printing plate-making process needs to first make a pattern negative through CTP plate-making, which requires a CTP to cooperate with the transfer medium, which requires two equipments to cooperate, one is a CTP plate-making machine, one is a printing machine

CTP belongs to the process of offset printing, which is borrowed into silk screen printing, which leads to the collaboration of cross-departmental processes, causing silk screen workers to not only do silk screen printing, but also cooperate with offset printing personnel, making it difficult for enterprises to coordinate in management, resulting in The process is cumbersome, the machine-made plate process cycle is long, the plate-making efficiency is low, and it is not conducive to the advancement of digital and intelligent manufacturing

[0006] Third, the cost is high: the cost of a single film is more than 100 yuan, and the annual consumption of a general printing factory is hundreds of thousands or even hundreds of thousands of sheets, which makes the cost too high
