Full-automatic etching device

Abstract

The invention discloses a full-automatic etching device which comprises an etching groove (1), a grabbing mechanism, a cross rod (8), a support (9) and a control box (10). The grabbing mechanism comprises a manipulator controller (11), a mechanical arm (12) and a manipulator (13), the manipulator controller (11) and the mechanical arm (12) are connected movably, the manipulator controller (11) is movably mounted on the cross rod (8), an etching agent pipe (5) and a detection device (3) are mounted on the etching groove (1), an inlet of the etching agent pipe (5) is connected with an etching pump (4) while an outlet of the same is positioned in the etching groove (1), the etching pump (4) is connected with an auxiliary etching groove (2), a gravimeter (31) and a probe (32) are arranged in the detection device (3), and a controller (6) is arranged on the side wall of the etching groove (1). The full-automatic etching device has the advantages of high automation level, high etching quality and low labor intensity.

Description

technical field [0001] The invention relates to an etching device, in particular to a fully automatic etching device. 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 continuously added to maintain a...

[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, the copper is continuously dissolved, and the content of monovalent copper ions in the potion rises. This means that divalent copper ions in the etching solution need to be continuously added to maintain a normal etching rate.

The addition of ammonia water and ammonium chloride is generally done by manually adding the etching solution, which is labor-intensive and has a large error range in the concentration control of the etching solution, and it is easy to cause poor etching quality of the circuit board
