[0023] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0024] like Figures 1 to 6As shown, the utility model provides an electroplating device, including an electroplating working tank 1, an electroplating mother tank 2 and an anode 3 arranged in the electroplating working tank 1, the anode 3 is used to release metal ions after power is turned on, a plurality of anodes 3 are arranged, all of the anodes 3 are arranged on the outside of the electroplated workpiece, arranged in a circle around the electroplated workpiece, and a chromium layer needs to be prepared on the surface of the electroplated workpiece.

[0025] Specifically, if Figures 1 to 4 As shown, the electroplating working tank 1 is a tank structure with a hollow interior, the anode 3 is located in the inner cavity of the electroplating working tank 1, a support assembly is arranged in the inner cavity of the electroplating working tank 1, the anode 3 is mounted on the support assembly, a fixed holder 4 and a movable holder 5 rotatably connected to the fixed holder 4 are arranged in the electroplating working tank 1, the fixed holder 4 and the movable holder 5 constitute a support assembly, and the fixed holder 4 and the movable holder 5 are both provided with the anode 3. A plurality of support assemblies are provided, and all support assemblies are arranged in sequence along the length direction of the electroplating working tank 1, the length direction of the anode 3 and the electroplating workpiece is parallel to the length direction of the electroplating working tank 1, and the electroplating workpiece is a roller.

[0026] like Figure 3 and Figure 4 As shown, two movable holders 5 are provided, and the two movable holders 5 are arranged oppositely and arranged at the upper end of the fixed holder 4, and the fixed holder 4 is fixedly arranged in the inner cavity of the electroplating working tank 1. Both the movable holder 5 and the fixed holder 4 are arc-shaped structures, the curvature of the fixed holder 4 is greater than the curvature of the movable holder 5, and the number of anodes 3 arranged on the fixed holder 4 is greater than the number of anodes 3 arranged on the movable holder 5. The two movable holders 5 are arranged symmetrically, and the rotation center line of the rotating connection between the movable holder 5 and the fixed holder 4 is parallel to the length direction of the anode 3. The movable holder 5 can rotate up and down, and the movable holder 5 is set to switch between an open state and a closed state. After the two movable holders 5 rotate toward the upper outer side of the fixed holder 4, the two movable holders 5 can be switched to an open state, so that the upper end of the fixed holder 4 is in an open state, and the electroplating workpiece can be taken and placed at this time. After placing the electroplated workpiece, the two movable retaining frames 5 are switched to the closed state, the ends of the two movable retaining frames 5 are in contact, and the upper end of the fixed retaining frame 4 is opened and closed. The two movable retaining frames 5 are in a coaxial state with the fixed retaining frame 4. At this time, all the anodes 3 are evenly distributed along the circumferential direction on the outside of the electroplated workpiece.

[0027] In the electroplating equipment with the above structure, during the electroplating operation, the supporting components and the anode 3 do not need to be rotated, the anode 3 is evenly distributed, and the chromium layer formed by electroplating on the entire circle of the electroplated workpiece is very uniform without color difference; and there is no need to set copper ring carbon brushes for conducting electricity, and no sparks will be generated, so the electroplating operation is relatively safe.

[0028] The speed of chromium plating on the entire outer circle of the electroplated workpiece is proportional to the strength of the magnetic lines of force at the plating position, which affects the uniformity of the color (brightness) of the chromium layer and is related to the uniformity of the magnetic line strength, the uniformity of the components of the chromium liquid, and the uniformity of the chromium liquid temperature.

[0029] like Figure 3 and Figure 4 As shown, the movable holder 5 is connected to the actuator 6, and the actuator 6 is configured to control the movable holder 5 to rotate. The actuator 6 is a retractable component, such as an electric cylinder, a hydraulic cylinder, an electric screw lifter, etc. One end of the actuator 6 is connected to the electroplating working tank 1, and the other end of the actuator 6 is connected to the movable holder 5.

[0030] like Figure 2 As shown, in this embodiment, a total of four supporting components are provided.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, a temperature control device is provided in the electroplating master tank 2. The temperature control device includes a cooling pipe 8 for guiding the flow of the coolant and an electric heating pipe 9 for heating, and the cooling pipe 8 and the electric heating pipe 9 are arranged in the electroplating master tank 2. The electroplating master tank 2 is an internal hollow tank structure, and the electroplating master tank 2 is located below the electroplating working tank 1. The cooling pipe 8 is arranged at the bottom of the inner cavity of the electroplating master tank 2, and the electric heating pipe 9 is arranged at the side of the inner cavity of the electroplating master tank 2. The electric heating pipe 9 generates heat after being energized, and the electroplating solution in the electroplating master tank 2 can be heated. The cooling pipe 8 is connected to an externally arranged water supply system, and the water supply system provides a coolant with a relatively low temperature to the cooling pipe 8, so as to cool down the electroplating solution in the electroplating master tank 2. Therefore, through the cooperation of the cooling pipe 8 and the electric heating pipe 9, the temperature of the electroplating solution is effectively controlled, and the temperature of the electroplating solution is made uniform.

[0032] Preferably, a filter pump is provided in the electroplating master tank 2, and the filter pump is connected to the electroplating working tank 1 through a pipeline, and the filter pump transports the electroplating solution in the electroplating master tank 2 to the electroplating working tank 1. The filter pump has a filtering function, which can filter particulate impurities in the electroplating solution to ensure a consistent concentration of the electroplating solution.
