Problems solved by technology

In the method of scouring etching, it is necessary to ensure that the etching solution is sprayed evenly and that the etching solution can flow away quickly after spraying to ensure that fresh etching solution is continuously washed to the surface of the material. So far, there is no effective technology to achieve the above requirements

Embodiment Construction

[0020] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0021] Such as figure 1 , 2 As shown, the etching device of the present invention is realized in this way, including a box-shaped frame 1, a rotating power a arranged on the frame 1, a rotating disk 2 driven by the rotating power a, and a rotating disk 2 arranged on the rotating disk 2. The workpiece fixing mechanism b and the etching liquid spraying mechanism c are special in that the rotating power a includes the motor drive mechanism 3, which is driven by the motor drive mechanism 3 (including motors, pulleys, belts or including motors, sprockets, and chains) to synchronize and The cam 4 rotates in the same direction, the transmission surface of the cam 4 is provided with a groove 5, the lower edge of the rotating disk 2 leans against the groove 5 of the transmission surface of the two convex, 4, and the upper part of the rotating disk 2 is provided wi...

Abstract

The invention discloses an etching method and device. The device is characterized in that two cams rotate; a rotating disc leaning against the two cams is driven to rotate; the rotating disc shakes upand down and left and right; a pumping device pumps an etching liquid to a nozzle on a vertical pipe on a side surface of the rotating disc and sprays the etching liquid out through the nozzle, a power mechanism drives a connecting rod to move left and right, the connecting rod drives a swing rod to swing, the vertical pipe rotates within a certain radian range, and the nozzle sprays the etchingliquid onto a workpiece on the rotating disc within a certain radian range. Compared with the prior art, by using the method and the device of the invention, advantages that the etching solution is sprayed uniformly, and the etching solution can flow away quickly after being sprayed are achieved.

Description

technical field [0001] The invention relates to an etching technique. Background technique [0002] Existing etching is to use etchant to continuously flush the surface of the board to be etched, and to erode the material on the board surface that is not covered (such as the copper plate part that is not covered by printing on the circuit board) until the board that is not covered The material on the face is completely removed, leaving the shaded parts. In the method of scouring etching, it is necessary to ensure that the etching solution is sprayed evenly and that the etching solution can flow away quickly after spraying, so as to ensure that fresh etching solution is continuously washed to the surface of the material. So far, there is no effective technology to achieve the above requirements. Contents of the invention [0003] The object of the present invention is to provide an etching method and device that can spray the etching liquid uniformly and quickly flow away...
