Method and device for stirring ink for printed circuit board

Abstract

The invention discloses a stirring method and device for evenly stirring printed circuit board ink. The impeller rotates around the agitating shaft due to the resistance encountered in the relative movement of the impeller; the agitating device includes a base, a rotating table and a bracket installed on the base, and the ink bucket is installed on the rotating table, and extends into the ink The stirring blade in the bucket is installed on the bracket through the connecting frame, the connecting frame includes a stirring shaft and a stirring blade seat, one end of the stirring shaft is connected with the support, the other end is connected with the inner ring of the bearing, and the outer ring of the bearing is connected with the stirring blade seat , two stirring blades are arranged on the stirring blade seat; because the present invention is provided with two stirring blades on the stirring shaft, and one is a left-handed stirring blade, and the other is a right-handed threaded stirring blade, so that the stirring blade is When the ink barrel rotates, the impeller rotates around the axis due to the resistance it receives, which speeds up the mutual diffusion speed of the two substances in the ink, and shortens the mixing time and mixing effect.

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 an ink stirring method and device for printed circuit boards. Background technique [0002] In the production process of printed circuit boards, it is often necessary to modulate 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 it can be used. If the mixing effect is not good, problems such as sticking of the negative film and incomplete curing after bridge drop will occur in the circuit board. In order to fully mix the ink, the existing ink mixer is generally a single-pole ink mixer, that is, an oil stirring knife is fixed on the support arm, and the ink tank is fixed in the rotating disk below, and the oil stirring knife is inserted into the ink. The ink tank rotates with the rotating plate driven by the m...

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
