Printing ink stirring method and device for printed circuit board

Abstract

The invention discloses a printing ink stirring method and device for a printed circuit board. The device comprises a rotary printing ink barrel and a stirring device, wherein two stirring blades on a stirring shaft move relative to printing ink when the printing ink barrel rotates, and the stirring blades rotate around the stirring shaft due to the fact that the stirring blades bear resistance in relative motion; the stirring device comprises a base, a rotary table and a support, the rotary table and the support are arranged on the base, the printing ink barrel is installed on the rotary table, the stirring blades extending into the printing ink barrel are installed on the support through a connection frame, the connection frame comprises the stirring shaft and a stirring blade base, one end of the stirring shaft is connected with the support, the other end of the stirring shaft is connected with an inner ring of a bearing, an outer ring of the bearing is connected with the stirring blade base, and the stirring blade base is provided with the two stirring blades. The two stirring blades are arranged on the stirring shaft, one is the left stirring blade, and the other is the right rotation thread stirring blade, so that when the stirring blades rotate in the printing ink barrel, the stirring blades rotate around the stirring shaft due to resistance, diffusion speed of two substances in the printing ink is increased, mixing time is shortened, and the mixing effect is enhanced.

Description

technical field [0001] The invention relates to a stirring method and device, in particular to an ink stirring method and device, in particular to a printing circuit board ink stirring method and device. Background technique [0002] During the production of printed circuit boards, it is often necessary to mix and stir printing inks. The ink is composed of two parts, the main agent and the curing agent. During production, the main agent and the curing agent must be fully mixed before use. If the mixing effect is not good, there will be problems such as sticking to the film locally on the circuit board, and incomplete curing after the bridge is dropped. In order to fully mix the ink, the existing ink mixers are generally single-knife ink mixers, that is, an oil mixing knife is fixed on the support arm, and the ink tank is fixed on the rotating disk below. The ink tank rotates with the rotating disk driven by the motor, and the oil stirring knife is fixed so that the ink in ...

AI Technical Summary

Problems solved by technology

When the stirring blade 52 rotates, a large hollow area will be formed in the middle of the ink tank to cause bubbles to hide therein, and when there are more inks, the volume of the stirring blade 52 itself will take up a certain space. If the ink tank rotates too fast, it will There is ink splashing out of the tank, and low-speed rotation will affect the effect and efficiency of stirring oil
