Description

Technical Field

[0001] This utility model belongs to the field of material surface treatment technology, specifically a safe and efficient coloring device for laboratory use. Background Technology

[0002] With industrial development, titanium alloy plates have been widely used in aerospace, medical, automotive, and sporting goods industries. These applications require not only excellent mechanical properties but also high visibility and corrosion resistance. Therefore, it is necessary to modify the surface characteristics of titanium alloy plates through material or chemical methods. The most common surface treatment method is anodizing, which involves mixing conductive salt solutions and coloring salt solutions of different concentrations in a specific ratio, then placing the mixture into the electroplating bath of an electrochemical plating device. The titanium alloy plate is then placed in the electroplating bath and energized. Depending on the current and the duration of energization, oxide films of different colors are formed on the surface of the titanium alloy, thereby improving its corrosion resistance.

[0003] Currently, the electrochemical plating equipment used in laboratories is generally a Hastelloy plating apparatus, which includes plating tanks and electrodes. By controlling parameters such as current, voltage, and electrolysis time, the surface color of titanium alloys can be made more uniform. However, it has the following problems: 1) For ease of operation, the plating tank is generally not covered. Firstly, the plating solution is volatile, which not only wastes the solution but also directly affects the plating quality due to changes in the concentration of the solution inside the tank. Furthermore, the volatile harmful substances irritate and damage the respiratory tract of operators, seriously endangering their health. Secondly, dust and other impurities enter the plating tank, contaminating the plating solution and affecting the quality of the oxide film; 2) It is difficult to accurately determine the concentration of the plating solution during the plating process, leading to untimely replenishment and large concentration fluctuations, affecting the quality of the oxide film; 3) Using heating rods to control the plating temperature is not only difficult to control within a reasonable range, but also, due to the lack of a cover, operators' hands can easily touch the heating rods, leading to burns or even electric shocks, which is extremely dangerous.

[0004] Therefore, existing Hastelloy plating equipment needs to be improved to enhance plating quality, conserve plating solution, and improve the working environment for laboratory operators, making plating safer and more efficient. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safe and efficient color plating device for laboratory use, which improves the quality, safety and efficiency of color plating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safe and efficient plating device for laboratory use includes a control console and an electroplating tank. The upper part of the electroplating tank is hinged with a cover. Temperature sensors, concentration sensors, cathode clamping parts, and anode clamping parts are fixedly installed inside the electroplating tank. A heating device for heating the electroplating solution inside the electroplating tank is fixedly installed at the bottom of the electroplating tank. A drain port is opened at the bottom of the electroplating tank and is equipped with a sealing cover. An exhaust port is opened on the upper side wall of the electroplating tank.

[0008] The console includes a housing, inside which a CPU module and a power supply device are installed. A display screen, a power switch, a keyboard, and a heating switch are embedded on the surface of the housing. Temperature sensors, concentration sensors, the display screen, the heating device, the keyboard, and the power supply device are all connected to the CPU module. The power supply device is connected to the cathode clamping part, the anode clamping part, and the power switch. The heating device is connected to the heating switch.

[0009] Furthermore, it also includes a conductive salt solution storage chamber and a coloring salt solution storage chamber respectively located on both sides of the electroplating tank. The side walls of the conductive salt solution storage chamber and the coloring salt solution storage chamber are provided with outlet holes that communicate with the electroplating tank, and the inlet holes are connected to solenoid valves, which are connected to the CPU module.

[0010] Furthermore, both the conductive salt solution storage chamber and the colored salt solution storage chamber are enclosed chambers. The top of the conductive salt solution storage chamber is provided with a conductive salt solution filling hole, and the top of the colored salt solution storage chamber is provided with a colored salt solution filling hole.

[0011] Furthermore, a master switch is also embedded on the surface of the housing, which is connected to the power switch, heating switch, CPU module and display screen respectively.

[0012] Furthermore, the exhaust port is connected to a pipe leading to the outside.

[0013] Furthermore, a base is fixedly installed at the bottom of the housing.

[0014] Furthermore, both the cathode clamping part and the anode clamping part include a base fixedly installed in the electroplating tank. A V-shaped opening is provided on the top of the base, and spring assemblies are fixedly installed on the opposite walls on both sides of the V-shaped opening.

[0015] The spring assembly includes at least one set of sleeves fixedly installed at the V-shaped opening, with springs inside the sleeves. One end of the spring is fixedly connected to the bottom of the sleeve, and the other end of the spring is fixedly installed with a spherical clamping head that can extend into the sleeve.

[0016] Furthermore, the temperature sensor is a PT00 resistance temperature sensor.

[0017] Furthermore, the concentration sensor is a quantum dot fluorescence sensor or a colorimetric sensor.

[0018] Furthermore, the lid is made of transparent glass.

[0019] Compared with the prior art, this utility model has the following technical effects:

[0020] Firstly, the hinged lid reduces the evaporation of the electroplating solution, prevents impurities from falling into the electroplating tank, improves electroplating quality, reduces waste of the electroplating solution, and minimizes the health risks posed by harmful or toxic gases or liquids to operators. Secondly, the heating device is located at the bottom of the electroplating tank, and the lid remains closed during the electroplating process, preventing operators from accidentally touching live parts, reducing the risk of electric shock, and improving operational safety. Thirdly, the concentration sensor monitors the concentration in real time, facilitating timely replenishment of the electroplating solution and reducing the decline in electroplating quality caused by a decrease in concentration. The invention addresses several key issues: Fourth, by using a temperature sensor, the temperature of the electroplating solution can be monitored in real time, allowing the CPU module to control the output of the heating device and meet heating requirements under different conditions; Fifth, by setting up an exhaust port, the evaporated electroplating solution and generated waste gas can be centrally discharged outdoors, improving the working environment of the laboratory. At the same time, the heat in the electroplating tank is also discharged, enhancing the heat dissipation effect of the electroplating tank; Sixth, by controlling the output voltage of the power supply device through the CPU module, it is suitable for coloring various titanium alloy plates; In conclusion, this invention improves the coloring quality and is safer and more reliable.

[0021] This invention uses a CPU module to control the opening and closing of a solenoid valve, which facilitates the quantitative replenishment of conductive salt solution and coloring salt solution to the electroplating bath, thereby improving plating efficiency.

[0022] This invention features a master switch that allows for quick shutdown of the CPU module display, heating device, and power supply after electroplating is complete, making it more convenient.

[0023] This invention utilizes a spring assembly in conjunction with a V-shaped opening at the top of the base. By leveraging the elastic restoring force of the spring, it can stably clamp the coated metal and titanium alloy plate, preventing them from falling off. Attached Figure Description

[0028] The specific content of this utility model will be further explained in detail below with reference to the embodiments.

[0029] like Figure 1 and Figure 2 As shown, a safe and efficient coloring device for laboratory use includes a control console, an electroplating tank, a conductive salt solution storage chamber 5, and a coloring salt solution storage chamber 12.

[0030] The upper part of the electroplating tank is hinged with a cover 9 made of transparent glass. During the electroplating process, covering the cover 9 can prevent the electroplating solution from evaporating, keep the concentration of the electroplating solution relatively stable, reduce the irritation and damage to the respiratory tract of the operator caused by harmful substances in the electroplating solution, and allow the abnormal conditions inside the electroplating tank to be observed through the transparent cover 9.

[0031] The electroplating tank is equipped with a temperature sensor 1, a concentration sensor 10, a cathode clamping part 6, and an anode clamping part 8. A heating device 14 for heating the electroplating solution inside the electroplating tank is fixedly installed at the bottom of the electroplating tank. A drain port 19 is provided at the bottom of the electroplating tank and is equipped with a sealing cover. An exhaust port 21 is provided on the upper side wall of the electroplating tank. The exhaust port 21 is connected to a pipe leading to the outside. Through the cooperation of the exhaust port 21 and the pipe, the volatile electroplating solution and the generated waste gas can be discharged, and the heat dissipation inside the electroplating tank can be facilitated.

[0032] like Figure 1 and Figure 3 As shown, both the cathode clamping part 6 and the anode clamping part 8 include a base fixedly installed in the electroplating tank. The top of the base has a V-shaped opening. Spring assemblies 18 are fixedly installed on the opposite walls on both sides of the V-shaped opening. The spring assembly 18 includes at least one set of sleeves fixedly installed at the V-shaped opening with opposite positions. A spring is installed inside the sleeve. One end of the spring is fixedly connected to the bottom of the sleeve. The other end of the spring is fixedly installed with a spherical clamping head that can extend into the sleeve. Through the elastic restoring force of the spring, it is convenient to clamp the plating metal and titanium alloy plate, which can effectively prevent the plating metal and titanium alloy plate from falling off.

[0033] Preferably, the temperature sensor 1 is a PT00 resistance temperature sensor, which has good corrosion resistance and can be used for real-time monitoring of the temperature of the electroplating solution for a relatively long period of time.

[0034] Preferably, the concentration sensor 10 is a quantum dot fluorescence sensor or a colorimetric sensor. In actual use, it can be selected according to the type of conductive salt. The colorimetric sensor is based on the quantum dot luminescence principle. Through the specific response of quantum dots to different metal ions, the change in metal ion concentration is converted into a color change, thereby realizing the detection of the metal ion concentration in the electroplating solution.

[0035] like Figure 1 and Figure 2 As shown, the conductive salt solution storage chamber 5 and the coloring salt solution storage chamber 12 are respectively arranged close to both sides of the electroplating tank, and the side walls of the conductive salt solution storage chamber 5 and the coloring salt solution storage chamber 12 are provided with liquid outlet holes that communicate with the electroplating tank. The liquid outlet holes are connected to solenoid valves. When the solenoid valves are opened, the pre-prepared conductive salt solution and coloring salt solution are added to the electroplating tank through the conductive salt solution storage chamber 5 and the coloring salt solution storage chamber 12, respectively.

[0036] Both the conductive salt solution storage chamber 5 and the colored salt solution storage chamber 12 are enclosed chambers. The top of the conductive salt solution storage chamber 5 is provided with a conductive salt solution filling hole, and the top of the colored salt solution storage chamber 12 is provided with a colored salt solution filling hole 13, so as to facilitate the replenishment of conductive salt solution and colored salt solution.

[0037] The control console includes a housing with a base 17 fixedly mounted on the bottom. Inside the housing are a CPU module 15 and a power supply device 16. The surface of the housing is fitted with a display screen 2, a power switch 3, a keyboard 4, a heating switch 20, and a main switch 7. Temperature sensor 1, concentration sensor 10, display screen 2, heating device 14, keyboard 4, solenoid valve, and power supply device 16 are all connected to the CPU module 15. Temperature and concentration thresholds, as well as the electroplating voltage, are input via the keyboard 4. The CPU module 15 controls the voltage applied by the power supply device 16 to the cathode clamping part 6 and the anode clamping part 8. During electroplating, the temperature sensor 1 and concentration sensor 10 transmit the collected data to the CPU module 15, which then transmits the data to the display screen 2 for the operator to view. When the electroplating solution concentration decreases, the CPU module 15 controls the solenoid valve to open, replenishing the electroplating tank with conductive salt solution and coloring salt solution until the electroplating solution concentration is the same as the set threshold.

[0038] The main switch 7 is connected to the power switch 3, the heating switch 20, the CPU module 15, and the display screen 3. The power supply device 16 is connected to the cathode clamping part 6, the anode clamping part 8, and the power switch 3. The heating device 14 is connected to the heating switch 20. The display screen 3 and the CPU module 15 are turned on by the main switch 7. The power supply device 16 is turned on by the power switch 3, which powers the cathode clamping part 6 and the anode clamping part 8. The heating device 14 is turned on by the heating switch 20 to heat the electroplating solution. When the temperature of the electroplating solution reaches the set value, the heating device 14 is controlled by the CPU module 15 to stop heating and maintain the temperature until the electroplating is completed.

[0039] The working principle of this utility model is as follows:

[0040] In use, the conductive salt solution and the coloring salt solution are first mixed in proportion to obtain the electroplating solution. The electroplating solution is added to the electroplating tank and stirred evenly with a glass rod. The titanium alloy plate is then clamped by the cathode clamping part 6, and the plating metal is clamped by the anode clamping part 8. The cover 9 is then closed and the main switch 7 is turned on. The electroplating voltage, electroplating solution concentration and temperature are input using the keyboard 4. The heating switch 20 is then turned on, and the heating device 14 is used to heat the electroplating solution. When the temperature reaches the set value, the heating is stopped and the temperature is maintained. Then the power switch 3 is turned on, and the CPU module 15 controls the power supply device 16 to apply the set voltage to the cathode clamping part 6 and the anode clamping part 8, and an electrolytic reaction occurs in the electroplating tank.

[0041] During the electroplating process, the concentration change of the electroplating solution is monitored in real time by a concentration sensor. The solenoid valve is opened or closed by the CPU module 5 to replenish the electroplating tank with the conductive salt solution in the conductive salt solution storage chamber 5 and the coloring salt solution in the coloring salt solution storage chamber 12. The CPU module 15 receives the data uploaded by the temperature sensor 1 and the concentration sensor 10 and displays the temperature inside the electroplating tank and the concentration of the electroplating solution on the display screen 2. The volatile electroplating solution mixed with waste gas and heat is discharged to the outside through the exhaust port 21 and the pipe connected to it.
