Problems solved by technology

The ink is squeezed by the scraper from the mesh to the COF substrate during the movement, and the resulting friction will cause a certain amount of wear to the scraper. Over time, the thickness accuracy of the printing ink will deviate, resulting in bad batches. At the same time, foreign matter generated by friction It will also cause foreign matter defects, and the scraper is expensive, which will cause waste

Embodiment 1

[0013] Embodiment 1: a kind of method of ink printing, it is characterized in that: comprise and utilize screen printing plate 1 graphic part mesh penetrating ink, the basic principle of non-graphic part mesh impermeable ink is printed, during printing, on silk screen The ink is poured into one end of the screen printing plate 1, and the printing roller 2 is used to apply pressure on the ink part of the screen printing plate 1, and at the same time, it is rolled towards the other end of the screen printing plate 1, and the ink is squeezed from the mesh by the roller 2 during the movement onto the COF substrate 3. During the printing process, the friction between the scraper and the screen printing plate 1 is eliminated, while the action of the printing roller 2 is horizontal rolling, and the friction force generated is extremely small and negligible, thus ensuring that the problems caused by wear , The ink thickness of the COF substrate is uneven, printing foreign matter, prin...

Embodiment 2

[0014] Embodiment 2: a kind of ink printing method, it is characterized in that: on the surface of printing roller 2 engrave printing picture and text, need not go through screen printing plate 1, printing roller 2 is stained with ink and directly rolls to COF substrate 3 horizontally In the printing process, the friction with the screen printing plate is also eliminated to ensure the accuracy and yield of the product.

[0015] Use the roller instead of the scraper to squeeze the ink horizontally through the screen printing plate and transfer it to the substrate, or directly replace the scraper and screen printing by drawing the pattern on the roller, so that the ink thickness of the product is more stable , to ensure the expansion and contraction of the product, bending resistance, insulation and the ability to protect the circuit.

Abstract

The invention relates to an ink printing method, and belongs to the technical field of ink printing. The ink printing method comprises the following steps: the printing is performed by using basic principles of transmitting ink through part of meshes of screen plate image-text parts and not transmitting the ink through part of meshes of non-image-text parts; during printing, the ink is poured in one ends of screen plates; printing rollers are used for applying pressure to the ink parts of the screen plates, and meanwhile, roll to the other ends of the screen plates; and the ink is extruded onto COF substrates from the meshes by the rollers during movement. The ink printing method has the following beneficial effects: the carving of images and texts by scrapers and rollers are directly replaced by a printing mode of scrapers and silk screens to directly solve the wear problem caused by friction through printing rollers; the problem of nonuniform ink thickness of the COF substrates is effectively improved; the problem of printing foreign matters can be greatly reduced; the scratch problem of the COF substrates is reduced; the maintenance cost and the scrap cost caused by the scraperwear are saved; and the production efficiency is improved.

Description

technical field [0001] The invention relates to an ink printing method and belongs to the technical field of ink printing. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It consists of resins, pigments, fillers, additives and solvents. It is used for various printing of books, magazines, packaging and decoration, architectural decoration and electronic circuit boards. With the rapid development of science and technology, the social demand is increasing rapidly, and the quality requirements for circuit board printing are getting higher and higher. However, the traditional tool that uses a scraper to scrape off the excess ink on the screen surface has the problem of easy wear and tear, which affects the ink during printing. ...
