Automatic coating device and automatic coating method with low flow rate and high precision

Abstract

The invention discloses an automatic coating device and an automatic coating method with a low flow rate and a high precision. The device comprises a coating dispensing controller and a robot controller. The robot controller controls an industrial multi-axis robot, the coating dispensing controller is acted to a mechanical precision pressure regulating valve and the mechanical precision pressure regulating valve is also connected to a low pressure coating supply device. The mechanical precision pressure regulating valve is fixed to the industrial multi-axis robot, and the coating dispensing controller is controlled by the robot controller. By adopting the device, a coated part is positioned to a corresponding position by a clamp, a coating fills the low pressure coating supply device, andthe mechanical precision pressure regulating valve driven by the industrial multi-axis robot moves in a position, needed to be coated, on the processed surface, so that the problem that the coating isnot uniform, is coated mistakenly and is splashed can be solved to a great extent, and the yield is high. By means of automation of process, artificial participation in the whole course is avoided, so that the efficiency is high.

Description

Technical field [0001] The invention relates to the field of electroplating protection or film coating, in particular to an automatic coating device and method with low flow rate and high precision. Background technique [0002] The workpiece needs to be subjected to surface electroplating process after processing to achieve surface protection. However, the electroplating process in different locations is different, the coating materials are different, and the protection requirements are also different; some areas do not need coating. During different electroplating processes, the remaining areas (different electroplating requirements areas and no coating areas) need to be protected. The protective measure is usually to apply a coating film on the surface, and then place the workpiece in the electroplating process device for electroplating treatment. [0003] The workpiece is not limited to small workpieces such as electronic product support plates and military products, and the c...

Problems solved by technology

[0004] At present, no such automatic equipment and corresponding production equipment that can realize the surface coating processing of small and complex parts have been found in domestic investigations and visits.

The method of realizing this process is basically to dip the paint with a hand-held brush and paint it on the surface of the corresponding protective position of the workpiece. Because the workpiece is small, and the surface shape and structure are complex and uneven, the coating film will be uneven and the paint will be easy to spray. Problems such as splashing to other parts (areas with different electroplating requirements and areas that do not require coating) lead to the failure to meet the protection requirements or electroplating process requirements, and the yield rate is low; the processing personnel have high technical requirements and low work efficiency; at the same time, the coating is harmful to the health of the staff. There is a certain danger
