Fully automatic printer for aluminum base plate

Abstract

The invention provides a four-column-type fully automatic printer for an aluminum base plate, and the four-column-type fully automatic printer comprises an automatic material inlet system, an automatic printing system and an automatic material outlet system. The automatic material inlet system conveys the aluminum plate through a conveyor belt; the automatic printing system comprises a printing screen plate, screen frames, a scraper, spray mouths, a workbench and automatic lifting columns, and the automatic printing system prints heat-conducting and insulating glue on the aluminum plate evenly; the material outlet system conveys the aluminum plate with the surface being printed a dense uniform insulation layer through the conveyor belt for the output; in a silk-screen printing system, theworkbench is supported by four automatic lifting columns, the surface of the workbench is provided with horizontal sliding electric guide rails in a paved manner, and the silk-screen printing system further comprises height sensors, a scraper moving rod and a rotating head; and the rotating head connects the scraper moving rod and the scraper, the height sensors are installed under the screen frames, and the workbench, the scraper moving rod, the spray mouths, positioning sensors and the height sensors are all connected with a general control platform and are controlled. The four-column-type fully automatic printer for the aluminum base plate has the characteristics of automatic material feeding, automatic positioning calibration, automatic printing and high production capacity.

Description

technical field [0001] The invention relates to a fully automatic printing machine, in particular to a fully automatic screen printing machine for producing aluminum substrates. Background technique [0002] The aluminum substrate is an aluminum-based copper-clad laminate. Generally, a single-sided panel consists of a three-layer structure, which is a circuit layer (copper foil), an insulating layer, and an aluminum-based layer. The double-sided board structure is a circuit layer, an insulating layer, an aluminum base, an insulating layer, and a circuit layer. Aluminum substrate, commonly used in LED lighting products. In the existing technology for producing aluminum substrates, it is necessary to make a thermally conductive adhesive film first, and then press the thermally conductive adhesive film with the pre-prepared aluminum plate and copper clad laminate to form the aluminum substrate. [0003] In the production process of aluminum-based copper-clad laminates, it is ...
