A resin ink vacuum plug hole printing device and printing method thereof

Abstract

The invention relates to a resin printing ink vacuum hole plugging printing device which comprises a main printing bin. A transit bin is arranged on one side of the main printing bin. The main printing bin and the transit bin are communicated. The transit bin comprises a bin body and a bin cover plate. The bin body is internally provided with a space capable of containing a printing platen. The printing platen is driven by a platen displacement transmission structure so that the position of the printing platen can be adjusted. The upper surface of the printing platen is provided with an isolation frame attached to the printing platen. The isolation frame is driven to ascend and descend vertically through a lifting assembly and is of a homocentric-squares-shaped structure. The isolation frame is attached to the upper surface of the printing platen when descending to the position of the lower end. A printed circuit board arranged on the upper surface of the printing platen is located in the homocentric-squares-shaped space of the isolation frame. After the bin cover plate is closed, the printed circuit board is located in the airtight space in the bin body. According to the resin printing ink vacuum hole plugging printing device, the defect that the working vacuum degree of a whole main printing bin needs to be damaged in each technological process of a traditional printing device is overcome; the printing efficiency is improved; and the stability of the quality of printed products is improved.

Description

technical field [0001] The invention belongs to the field of PCB production, in particular to a printing device for a PCB board, in particular to a resin ink vacuum plug hole printing device and a printing method thereof. Background technique [0002] There are many holes on the surface of the PCB circuit board, and the holes on the surface need to be filled with resin to make the surface smooth. Now a vacuum plugging machine is often used to plug the holes in the technology. In order to make the filling uniform, the printing machine prints in a vacuum state, and the pressure difference generated by reducing the vacuum degree fills the resin to the depth of the hole. For example, install a printing machine in a container with a closed structure, open the door of the container, move the workbench with the printed circuit board on it into the container, and then vacuum the inside of the container with a vacuum pump while the door is closed. Printing is carried out in the case...
