[0024] The mixing mechanism also includes a mixing motor 201, a density concentration detector 202 is provided inside the electroplating pool 1, the surface of the electroplating pool 1 is rotatably connected to a mixing shaft 203, the surface of the mixing shaft 203 is fixedly connected to a transmission pulley 204, the surface of the mixing shaft 203 is fixedly connected to the surface of the mixing blade 2, the transmission pulley 204 is located outside the electroplating pool 1, and the mixing blade 2 is located inside the electroplating pool 1.
[0025] Furthermore, the density concentration detector 202 detects the concentration of the plating solution inside the electroplating cell 1 online, and the mixing motor 201 drives the mixing blade 2 to rotate via the mixing shaft 203 to fully mix the plating solution inside the electroplating cell 1 .
[0026] The surface of the mixing motor 201 is fixedly connected to the surface of the electroplating pool 1, and the output shaft of the mixing motor 201 is fixedly connected to one end of the mixing shaft 203 through a coupling. Multiple mixing shafts 203 are distributed in a linear array along the axial direction of the electroplating pool 1, and the surfaces of multiple transmission pulleys 204 are all connected through belt drive.
[0027] Furthermore, the mixing motor 201 drives the mixing blades 2 to rotate through the mixing shaft 203, and the transmission pulleys 204 on the surfaces of the multiple mixing shafts 203 are all connected through belt drive to achieve synchronous rotation of the multiple mixing shafts 203, thereby jointly mixing the electroplating liquid inside the electroplating tank 1.
[0028] When the existing device is used to plate a metal, the main body of the device needs to discharge continuously, which causes the concentration of the plating solution inside the electroplating tank 1 to continuously decrease. In order to maintain the stability of the plating solution concentration inside the electroplating tank 1 and avoid the continuous decrease in the concentration of the plating solution inside the electroplating tank 1 resulting in inconsistent thickness of the electroplated coating, an adjustment mechanism is provided. Figure 1 and Figure 3 The regulating mechanism includes a regulating box 3 , and the regulating mechanism adjusts the concentration of the internal electroplating solution of the electroplating cell 1 by regulating the electroplating solution inside the regulating box 3 .
[0029] The regulating mechanism also includes an electric heating tube 301. A top cover 302 is fixedly connected to the top of the regulating box 3. A filling port 303 is provided on the surface of the top cover 302. An observation window 304 is provided on the surface of the regulating box 3. A temperature sensor 305 and a connecting tube 306 are respectively provided on the surface of the regulating box 3. The two regulating boxes 3 are symmetrically distributed with the axis of the electroplating pool 1 as the center.
[0030] Furthermore, two regulating boxes 3 are provided, each containing a high-concentration and a low-concentration plating solution, which are mixed with the plating solution in the plating pool 1 as required. The state of the plating solution in the regulating box 3 is observed through the observation window 304, and timely filling is performed to avoid lack of plating solution and inability to mix.

[0032] Furthermore, the electric heating tube 301 heats the plating liquid inside the regulating box 3 to avoid excessive temperature changes in the mixed plating liquid that affect the thickness of the metal coating. The top cover 302 is removable to facilitate maintenance and replacement of the electric heating tube 301. The temperature sensor 305 detects the temperature of the plating liquid at the water outlet position at the bottom of the regulating box 3.
[0033] The two ends of the connecting pipe 306 are fixedly connected to the water inlet of the electroplating pool 1 and the water outlet of the regulating box 3 respectively.

[0035] By setting up a mixing mechanism and an adjusting mechanism, the adjusting mechanism introduces the plating solution of different concentrations inside the regulating box 3 into the interior of the electroplating pool 1, and the mixing mechanism mixes the plating solution inside the electroplating pool 1 evenly through the mixing blades 2, thereby avoiding uneven concentration of the plating solution in different places. This solves the technical problem that when the existing metal plating device is in use, the concentration of the plating solution inside the electroplating pool 1 continues to decrease, resulting in inconsistent plating thickness of the workpiece.
[0036] Working principle:
[0037] Before use, the workpiece is electroplated inside the electroplating tank 1, which causes the concentration of the plating solution inside the electroplating tank 1 to continuously decrease, the time required for electroplating becomes longer and the thickness of the metal coating is uneven. The density concentration detector 202 set inside the electroplating tank 1 is used to detect the concentration of the plating solution inside the electroplating tank 1 online. When the concentration of the plating solution inside the electroplating tank 1 exceeds the set range, the regulating water pump 307 outside the electroplating tank 1 can be driven to pump the plating solution inside the regulating box 3 into the interior of the electroplating tank 1 through the connecting pipe 306. A one-way valve 308 is set on the surface of the connecting pipe 306 to prevent the plating solution from flowing back. An electric heating pipe 301 is set inside the regulating box 3 to heat the plating solution inside the regulating box 3. A temperature sensor 305 is set to monitor the temperature of the plating solution at the water outlet position at the bottom of the regulating box 3 to avoid excessive temperature changes of the mixed plating solution that affect the thickness of the electroplated coating. Two regulating boxes 3 are set The plating solutions containing high concentration and low concentration are mixed with the plating solution inside the plating tank 1 as needed. The state of the plating solution inside the regulating box 3 is observed through the observation window 304, and timely filling is done to avoid lack of plating solution and inability to mix. After the plating solution inside the regulating box 3 is pumped into the plating tank 1, the mixing motor 201 of the plating tank 1 is driven. The mixing motor 201 drives the mixing blade 2 to rotate through the mixing shaft 203. The transmission pulleys 204 on the surfaces of the multiple mixing shafts 203 are all connected by belt drive to achieve synchronous rotation of the multiple mixing shafts 203, and jointly mix the plating solution inside the plating tank 1. The drain valve 310 arranged on the outside of the plating tank 1 is opened to discharge the plating solution inside the plating tank 1 from the drain pipe 309, thereby reducing the total amount of plating solution inside the plating tank 1, facilitating the mixing of the plating solution inside the regulating box 3, and reducing the consumption of plating solution inside the regulating box 3.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
