Automatic etching and cleaning device for PCB

Abstract

The invention discloses an automatic etching and cleaning device for a PCB, and the device comprises an etching tank, a cleaning tank, a grabbing mechanism, a cross bar, a support, and a control box. The grabbing mechanism comprises a mechanical arm controller, a mechanical arm, and a mechanical hand. The etching tank is provided with an etching agent tube, and the inlet of the etching agent tube is connected with an etching pump. The outlet of the etching agent tube is located in the etching tank, and the etching pump is connected with an etching auxiliary tank. The interior of a detection apparatus is provided with an aerometer and a probe. A side wall of the etching tank is provided with a controller, and two side walls of the cleaning tank are respectively provided with a plurality of tap water pipes. The outlets of the plurality of tap water pipes are located in the cleaning tank, and are sequentially provided with a plurality of high-pressure spraying heads from the top to the bottom. The bottom of the cleaning tank is provided with a tapered tank, and the bottom of the tapered tank is provided with a water outlet pipe. The beneficial effects of the invention are that the device is high in automation degree, is good in etching quality, and is good in cleaning quality.

Description

technical field [0001] The invention relates to an etching cleaning device, in particular to an automatic etching cleaning device for a PCB board. Background technique [0002] With the recovery of the electronics industry, the development of China's circuit board industry has also generally rebounded. China will become the world's largest PCB industry base in recent years, accounting for about 30% of the global market. In the production process of printed circuit boards, etching is It is a very important process, and a large amount of etching solution must be used during etching. However, the existing etching equipment is not highly automated and often requires manual operation. However, the etching solution is highly corrosive and is likely to cause harm to workers. Moreover, as the etching progresses, copper is continuously dissolved, and the content of monovalent copper ions in the potion rises, which means that divalent copper ions in the etching solution need to be con...
