[0020] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0021] An etching device for touch screen production includes an etching box 1, wherein a water outlet pipe 2 at the bottom of the etching box 1 is connected to a reagent box 3, and the reagent box 3 is connected to the etching box 1 through a circulation pipe 4, and a pump 5 is provided on the circulation pipe 4:

[0022] The outlet pipe 2 is provided with a V-shaped pipe 6 coaxially arranged therewith, wherein one end of the V-shaped pipe 6 extends to the outside of the outlet pipe 2 and is connected to a longitudinally arranged cylinder 7, and both ends of the cylinder 7 are sealed, wherein a return pipe 8 connected to the medicine box 3 is provided on one side of the bottom of the cylinder 7;

[0023] The etching box 1 is provided with a filter screen cover 9 in a quadrangular pyramid structure and inverted, wherein a vertical pipe 10 extending into the water outlet pipe 2 is provided in the middle of the bottom of the filter screen cover 9, and the vertical pipe 10 is covered on the V-shaped pipe 6;

[0024] An operating port 11 opposite to the V-shaped tube 6 is provided on one side of the top of the cylinder 7, wherein a switch door 12 is provided at the operating port 11, a rotating shaft 13 driven by a motor is provided at the center of the cylinder 7, wherein four groups of filter plates 14 are radially provided on the outer wall of the rotating shaft 13, and one group of filter plates 14 is vertically arranged and located between the operating port 11 and the V-shaped tube 6, a baffle 15 extending to the inside of the cylinder 7 is provided above the cylinder 7, wherein the baffle 15 is in contact with one end face of the filter plate 14 located above, and the baffle 15 is driven by an electric push rod 16, and a strip opening for the baffle 15 to pass through is provided on the top wall of the cylinder 7, wherein the baffle 15 seals the aperture on the upper filter plate 14.

[0025] like Figure 1 As shown, a circle of support bars 17 located below the filter screen cover 9 is arranged around the bottom of the etching box 1, wherein the filter screen cover 9 is fixed to the support bars 17 by bolts, and a handle is arranged on the filter screen cover 9.

[0026] In this embodiment, the aperture of the filter plate 14 is smaller than the aperture of the side wall of the filter screen cover 9 , wherein one end of the filter plate 14 is fixedly connected to the outer wall of the rotating shaft 13 , and the other end thereof abuts against the inner wall of the cylinder 7 .

[0027] like Figure 1 , 2 As shown, a circular ring 18 for supporting the bottom end of the vertical pipe 10 is provided on the V-shaped pipe 6 in the water outlet pipe 2 , wherein the diameters of the circular ring 18 and the vertical pipe 10 are both smaller than the inner diameter of the water outlet pipe 2 .

[0028] In this embodiment, solenoid valves for controlling the opening and closing of the water outlet pipe 2, the V-shaped pipe 6 and the return pipe 8 are all provided.

[0029] like Figure 2 As shown, the operation port 11 and the V-shaped tube 6 are both located on the side wall of the cylinder 7 between the two corresponding groups of filter plates 14 .

[0030] The working principle of the present invention is as follows: Figure 1 As shown, the corrosion-resistant pump 5 can transport the reagent in the reagent box 3 to the etching box 1 through the circulation pipe 4, and then the reagent in the etching box 1 will enter the interior of the reagent box 3 through the outlet pipe 2. In the above process, the waste residue generated in the etching box 1 is filtered through the filter screen 9 to prevent the waste residue from settling to the bottom of the etching box 1, which makes it difficult for people to clean it. At the same time, the liquid that flows back into the reagent box 3 can also be filtered;

[0031] When the filter screen cover 9 is accumulated with impurities after being used for a certain period of time, the etching box 1 is still in normal processing and cannot be taken out from the inside thereof, and a large amount of impurities are accumulated on the filter screen cover 9 and affect the flow of liquid, the V-shaped tube 6 can be opened to allow the impurities and liquid above the filter screen cover 9 to flow to the vertical tube through its inclined surface, and then flow through the V-shaped tube 6 into the space between the two sets of filter plates 14 in the cylinder 7, as shown in detail. Figure 1 , 2 As shown, the liquid mixed with impurities is filtered through the filter plate 14, and finally the liquid enters the medicine box 3 through the reflux pipe 8. After a certain period of time, the motor drives the rotating shaft 13 to drive the filter plate 14 to rotate 90 degrees counterclockwise. During this process, the electric push rod 16 drives the baffle 15 to move up to prevent it from affecting the rotation of the filter plate 14. Then the baffle 15 moves down to block the right side of the upper filter plate 14. At this time, the filter plate 14 with impurities is moved to the top area on the left side of the cylinder 7. People can remove the accumulated impurities through the opened operating port 11. In the above process, the baffle 15 can block the liquid introduced by the V-shaped tube 6 to prevent it from splashing to the operating port 11 and spilling out, or to prevent the liquid from splashing to the top area on the left side of the cylinder 7 and affecting people from removing the filtered impurities.

[0032] Meanwhile, in the above process, the position of the filter plate 14 can be changed by rotating it, so that it can filter the liquid and clean the impurities in the filter at the same time. When the impurities on the filter screen cover 9 are basically cleaned, the V-shaped tube 6 is closed, so that the filter screen cover 9 filters the liquid, and the liquid flows into the reagent box 3 through the outlet pipe 2. When the etching box 1 is finally stopped, the filter screen cover 9 can be taken out for thorough cleaning.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
