They are mainly used to carve by eroding the material. They are widely used in the etching process of circuit boards. During the etching process of circuit boards using acid-base etching solutions, a large amount of etching waste liquid is generated. It is usually directly discarded. However, the large amount of ammonium ions and the small amount of copper ions contained in it cannot be effectively utilized, resulting in resource waste.

[0024] Please see Figure 1-4 This utility model provides an embodiment: an electrolytic copper purification device for acid and alkali etching solution treatment, including a device base 2, a top seat 4 at the top of the device base 2, an anode plate 5 fixedly installed on the left side of the bottom end of the top seat 4, a cathode plate 6 fixedly installed on the right side of the bottom end of the top seat 4, a lifting seat 11 at the bottom inside the device base 2, and an electrolytic cell 8 at the top of the lifting seat 11, a lead screw 14 vertically movably connected to both sides inside the device base 2, and a threaded sleeve 13 rotatably connected to the outside of the lead screw 14, the bottom end of the lead screw 14 penetrating the bottom inside the device base 2 and fixedly having a helical gear 18, a connecting shaft 16 horizontally movably connected to the bottom inside the device base 2, and helical gears 17 fixedly installed on both sides of the outside of the connecting shaft 16, a reducer 12 fixedly installed at the bottom right side of the device base 2, and a servo motor 15 fixedly installed at the top of the reducer 12;

[0025] The threaded sleeve 13 is symmetrically arranged about the vertical center line of the equipment base 2. The right side of the left threaded sleeve 13 is fixedly connected to the left side of the lifting base 11, and the left side of the right threaded sleeve 13 is fixedly connected to the right side of the lifting base 11. The output shaft of the servo motor 15 is fixedly connected to the input shaft of the reducer 12. The output shaft of the reducer 12 is fixedly connected to the right side of the connecting shaft 16. The first helical gear 17 and the second helical gear 18 are meshed together.

[0026] Specifically, such as Figure 1 and Figure 2As shown, after the acid-base etching solution is introduced into the electrolytic cell 8, the connecting shaft 16 can be driven to rotate by the servo motor 15 through the reducer 12. The rotation of the connecting shaft 16 can drive the two sets of lead screws 14 to rotate by the meshing helical gear 17 and helical gear 18. At the same time, the rotation of the lead screws 14 can drive the lifting seat 11 to move upward inside the equipment base 2 by the threaded sleeve 13, and at the same time, it can drive the electrolytic cell 8 to move upward, so that the top anode plate 5 and cathode plate 6 are immersed in the acid-base etching solution to carry out the electrolytic reaction. The etching waste liquid is extracted to extract high-purity electrolytic copper through electrolytic deposition, so that the copper ions in the alkaline etching waste liquid are reduced. After the electrolysis is completed, the servo motor 15 can be reversed to lower the electrolytic cell 8 back to the initial position, so that the deposited electrolytic copper on the anode plate 5, cathode plate 6 and inside the electrolytic cell 8 can be easily processed.

[0027] The bottom end of the top seat 4 is provided with a top cover 7, and the top cover 7 has an opening 22 inside. Guide rods 19 are fixed on both sides of the top end of the top cover 7. Sliding sleeves 20 are fixed inside both sides of the top end of the top seat 4. Compression springs 21 are fixed on both sides of the bottom end of the top seat 4.

The top end of the guide rod 19 passes through the inside of the sliding sleeve 20.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when the acid-base etching solution is introduced into the electrolytic cell 8 for upward electrolytic treatment, a top cover 7 is provided on the top to help seal the inside of the electrolytic cell 8 and prevent the acid-base etching solution from splashing outward during the electrolysis process.

[0029] The front end of the equipment base 2 is provided with a front plate 1, and the rear end of the equipment base 2 is provided with a rear plate 9. Two sets of connecting feet 23 are fixed on the left side of the front plate 1 and the rear plate 9 respectively. Two sets of connecting frames 24 are fixed at both ends of the left side of the equipment base 2 respectively. The connecting feet 23 and the interior of the connecting frames 24 are hinged. Locking rods 25 are movably connected to the right side of the front end of the front plate 1 and the right side of the rear end of the rear plate 9 respectively. Fixing frames 10 are fixed at both ends of the right side of the equipment base 2 respectively, and locking grooves 26 are opened in the interior of the top of the fixing frames 10 respectively. The locking rods 25 pass through the interior of the locking grooves 26.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, the rear plate 9 and the front plate 1 can be rotated inward and attached to the two ends of the equipment base 2 respectively. Then, the locking rod 25 can be rotated downward and inserted into the locking groove 26 to lock the front plate 1 and the rear plate 9 on the outside of the equipment base 2. The front plate 1 and the rear plate 9 can not only provide auxiliary sealing for the electrolytic processing area of ​​the equipment, but also provide auxiliary anti-collision protection for the outside of the equipment.

[0031] Support rods 3 are fixed on both sides of the top of the equipment base 2, and the top of the support rods 3 are fixedly connected to the bottom of the top base 4.

[0032] Working Principle: In use, after the acid-base etching solution is introduced into the electrolytic cell 8, the connecting shaft 16 is driven to rotate by the servo motor 15 and the reducer 12. The rotation of the connecting shaft 16 drives two sets of lead screws 14 to rotate through the meshing helical gears 17 and 18. Simultaneously, the rotation of the lead screws 14 drives the lifting seat 11 to move upward inside the equipment base 2 through the threaded sleeve 13, which in turn moves the electrolytic cell 8 upward, immersing the top anode plate 5 and cathode plate 6 into the acid-base etching solution for electrolytic reaction. The etching waste liquid is then electrolytically deposited to extract high-purity electrolytic copper, thus reducing the copper ion content in the alkaline etching waste liquid. After electrolysis is completed, the servo motor 15 can be reversed to lower the electrolytic cell 8 back to its initial position. This allows for rapid processing of the deposited electrolytic copper on the anode plate 5, cathode plate 6, and inside the electrolytic cell 8. Simultaneously, when the acid-base etching solution is introduced into the electrolytic cell 8 for upward electrolysis, a top cover 7 is provided to provide auxiliary sealing to prevent liquid splashing inside the electrolytic cell 8. Furthermore, during the electrolytic purification of electrolytic copper, a flip-up and closable rear plate 9 and front plate 1 are provided at both ends of the equipment base 2. The front plate 1 and rear plate 9 not only provide auxiliary sealing for the electrolysis processing area but also provide auxiliary anti-collision protection for the outside of the equipment.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
