Screen printing device and screening printing method thereof

Abstract

The invention provides a screen printing device and a screening printing method thereof. The screen printing device comprises a supporting plate, a guide structure, a conveyor belt, scraping knife components, a cross beam and lifting arms. The supporting plate comprises a rotating plate, adsorption layers and lifting rods, wherein the adsorption layers are arranged on the upper surface and the lower surface of the rotating plate and are uniformly provided with suction holes; the lifting rods are arranged at the two ends of the rotating plate; the rotating plate is internally provided with a rotating motor and can rotate with the lifting rods as the axis. When the screen printing device conducts screen printing, the top end of the guide structure is flush with the lower surface of the adsorption layer on the lower portion. The conveyor belt is arranged on the lower portion of the guide structure. The scraping knife components are arranged above the supporting plate. The lower portion ofthe cross beam is provided with a slide rail. The slide rail is matched with telescopic cylinders. A screen plate is connected with the cross beam through connecting rods. The lifting arms are arranged on the two sides of the supporting plate and the cross beam. The lifting rods and the cross beam are connected with the lifting arms. The screening printing device can adsorb a plurality of printedscreens through the adsorption layers of the supporting plate simultaneously, the screen printing efficiency is greatly improved, and the screen printing cost is reduced.

Description

technical field [0001] The invention relates to a screen printing device, in particular to a screen printing device and a silk screen printing method. Background technique [0002] Silk screen printing, that is, screen printing, is to attach a template with images or patterns to the screen, and use photochemical plate-making or hand-carved paint film to make a screen printing plate for printing. In order to ensure the accuracy of the screen printing pattern or area, the screen printing screen must be strictly aligned with the substrate. At present, silk screen printing is generally realized by semi-automatic equipment. The operator places the glass screen on the screen printing fixture and triggers the start button, and the equipment will automatically align the screen printing fixture. Silk screen printing on the glass screen on the screen has low efficiency and poor precision, which cannot meet today's mass production. After ITO prints the silver glue, in order to protect...
