Circuit board double-roller ink coating machine and working method thereof

Abstract

The invention discloses a circuit board double-roller ink coating machine. The circuit board double-roller ink coating machine comprises a machine body, the bottom of the machine body is provided with an electric cabinet, an ink stirring device and a pneumatic diaphragm pump, the electric cabinet is arranged on the right side of the machine body, the ink stirring device is arranged on the left side of the machine body, the pneumatic diaphragm pump is arranged in the middle of the machine body, two coating mechanisms are arranged side by side at a discharge end of a silica gel delivery roller, an automatic dust adhesion roller and a paper rolling device are arranged on the joint of the silica gel delivery roller and coating mechanisms, an ink receiving tray is arranged below the coating mechanisms and is located above the ink stirring device, and a circulating ink outlet pipe is arranged in the middle of the ink receiving tray. The coating machine adopts simultaneous rolling of the double coating rollers to coat the surface of a base plate with a layer of photosensitive ink so that the level of the product is improved and can use two different inks at the same time so that the replacement time is reduced.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a working method of a circuit board two-wheel ink coating machine. Background technique [0002] Existing ink coating machines generally require workers to screen-print full-page circuit boards. The entire process is manually operated. The process is very cumbersome and complicated, and the degree of automation is low. The cost is high, the production efficiency is low, and the time for each screen printing is too long, which makes it difficult to meet the production needs of large quantities of products. Moreover, due to the differences in manual operations, it is difficult to maintain the same quality of circuit boards in each batch, which may easily lead to insufficient product quality. Stable and reliable, high defective rate. This technical solution proposes a two-wheel photosensitive ink machine, which uses a double-wheel coating roller to simultaneously roll a layer of ph...
