Description

Technical Field

[0001] This utility model relates to an etching machine with recyclable etching solution, belonging to the technical field of etching machines. Background Technology

[0002] An etching machine is a piece of equipment used for material processing, widely applied in fields such as electronics, semiconductors, microelectromechanical systems (MEMS), optics, and mechanical manufacturing. It removes specific portions of a material's surface using chemical or physical methods, thereby achieving patterning or structuring.

[0003] Existing etching machines can only use etching solution once, which wastes the etching solution. At the same time, it is necessary to manually add new etching solution, which affects the efficiency of the etching machine. According to the patent with publication number CN204918774U, although the patent designed an automatic etching solution circulation function, the position of the nozzle cannot be adjusted, which will lead to uneven etching. In addition, the recovery tank cannot be cleaned after multiple etchings, which affects subsequent use. Utility Model Content

[0004] The technical problem this invention aims to solve is that the position of the nozzle in existing etching machines cannot be adjusted, which leads to uneven etching. Furthermore, the recovery tank cannot be cleaned after multiple etching processes, affecting subsequent use.

[0005] To address the aforementioned problems, this utility model provides a recyclable etching solution etching machine, comprising a body and support legs. The body is located on the upper end of the support legs. A spray head is slidably connected to the upper part of the body via a slide rail. A support frame is slidably mounted on one side of the body. A filter screen is provided at the lower end of the support frame. A liquid storage tank is provided at the lower end of the body. A water pump is located on the outside of the body. Both ends of the water pump pass through the body and communicate with the spray head and the liquid storage tank, respectively. A scraping mechanism is connected to one side of the liquid storage tank via a telescopic rod. A drain plug is inserted at the lower end of the body.

[0006] Furthermore, the upper end of the spray head is provided with a slider, and the spray head is slidably connected to the slide rail via the slider.

[0007] Furthermore, one side of the spray head is connected to one end of the water pump via a telescopic pipe.

[0008] Furthermore: the scraping mechanism includes a U-shaped plate, a rotating shaft, and scrapers. The U-shaped plate is fixedly connected to one end of the telescopic rod, and the two ends of the rotating shaft are rotatably connected to the U-shaped plate. Several scrapers are arranged on the outside of the rotating shaft.

[0009] Furthermore, a drainage groove is provided at the lower end of the machine body at the position corresponding to the drain plug.

[0010] Furthermore, a pull handle is provided on one side of the support frame.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] This patent uses a sliding rail to adjust the position of the spray head, which effectively ensures the uniformity of etching. At the same time, after multiple uses, the residual etching solution on the bottom of the storage tank can be scraped off by the scraping mechanism to prevent the residual etching solution from affecting subsequent use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Combined with appendix Figure 1-4This utility model provides an etching machine with recyclable etching solution, including a body 1 and support legs. The body 1 is located on the upper end of the support legs. A spray head 2 is slidably connected to the upper part of the body 1 via a slide rail 21. The slide rail 21 is an electric slide rail 21. A slider 22 is provided on the upper end of the spray head 2, and the spray head 2 is slidably connected to the slide rail 21 via the slider 22. One side of the spray head 2 is connected to one end of a water pump 13 via a telescopic tube 23. A support frame 11 is slidably mounted on one side of the body 1. A pull handle is provided on one side of the support frame 11. A filter screen 12 is provided at the lower end of the support frame 11. A liquid storage tank 3 is provided at the lower end of the body 1. A water pump 13 is provided on the outside of the machine body 1. One end of the water pump 13 passes through the machine body 1 and is connected to the liquid storage tank 3. When in use, the workpiece is placed on the support frame 11 and pushed into the machine body 1. The etching solution is drawn out from the liquid storage tank 3 by the water pump 13 and transported to the spray head 2 through the pipeline. The slide rail 21 adjusts the position of the spray head 2 so that the spray head 2 sprays the etching solution evenly on the surface of the workpiece to be etched. The spray head 2 can evenly cover the etching area, improve the uniformity and quality of etching. After the etching process is completed, the etching solution is filtered by the filter screen 12 and drips back into the liquid storage tank 3 so that it can be recycled in the future.

[0022] Combined with appendix Figure 1-4 A scraping mechanism 4 is connected to one side of the liquid storage tank 3 via a telescopic rod 31. A drain plug is inserted at the lower end of the machine body 1. The scraping mechanism 4 includes a U-shaped plate 41, a rotating shaft 42, and scrapers 43. The U-shaped plate 41 is fixedly connected to one end of the telescopic rod 31. The rotating shaft 42 is an electric rotating shaft 42. Both ends of the rotating shaft 42 are rotatably connected to the U-shaped plate 41. Several scrapers 43 are arranged on the outside of the rotating shaft 42. A drainage channel is provided at the lower end of the machine body 1 at the position corresponding to the drain plug. When it is necessary to clean the liquid storage tank 3, the support frame 11 is taken out, and the liquid storage tank 3 is sprayed with an external water pipe. At the same time, the telescopic rod 31 pushes the scraping mechanism 4, and the scrapers 43 rotate under the drive of the rotating shaft 42 to scrape off the residual etching liquid and impurities on the bottom surface of the liquid storage tank 3. The cleaned etching liquid can be discharged through the drain plug, and the drainage channel guides the etching liquid to flow out of the machine body 1.

[0023] The working principle of this application is as follows:

[0024] During use, the workpiece is placed on the support frame 11 and pushed into the machine body 1. The etching solution is drawn from the storage tank 3 by the water pump 13 and transported to the spray head 2 through the pipeline. The slide rail 21 adjusts the position of the spray head 2 so that the spray head 2 sprays the etching solution evenly on the surface of the workpiece to be etched. The spray head 2 can evenly cover the etching area, improving the uniformity and quality of etching. After the etching process is completed, the etching solution is filtered by the filter screen 12 and drips back into the storage tank 3 for subsequent recycling. When it is necessary to clean the storage tank 3, the support frame 11 is removed and the storage tank 3 is sprayed with an external water pipe. At the same time, the telescopic rod 31 pushes the scraping mechanism 4. The scraper 43 rotates under the drive of the rotating shaft 42 to scrape off the residual etching solution and impurities on the bottom surface of the storage tank 3. The cleaned etching solution can be discharged through the drain plug, and the drainage channel guides the etching solution to flow out of the machine body 1.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
