Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to an electroplating device. Background Art

[0002] Electroplating is a process that utilizes electrochemical reactions to plate a thin layer of other metals or alloys on the workpiece to be plated, such as a battery cell or on the surface of certain metals or other materials. During the electroplating process, in order to eliminate the interference of other cations and make the coating uniform and firm, a solution containing the coating metal cation is usually used as the electroplating solution, and the coating metal or other insoluble materials are used as the anode. The concentration of the coating metal cations in the solution is kept constant, and the workpiece to be plated is immersed in the electroplating solution, and the workpiece to be plated is used as the cathode. After the electroplating process, the workpiece to be plated deposits a metal coating with properties different from the base material, which plays the role of anti-corrosion and anti-rust, protective decoration, and improving wear resistance, electrical properties, and reflectivity.

[0003] At present, immersion electroplating is generally adopted. The electroplating equipment includes an electroplating tank and a fixture. The electroplating solution is contained in the electroplating tank. After the fixture clamps the workpiece to be plated, the workpiece to be plated is slowly placed in the electrolytic tank, and then powered on. Under the action of the potential difference, the metal cations in the electroplating solution move toward the cathode (the workpiece to be plated) and are reduced on the surface of the workpiece to be plated to form a coating. After the coating is attached, the power is turned off and the workpiece to be plated is taken out. However, in the above-mentioned electroplating equipment, the electroplating solution in the electroplating tank is prone to ion deposition when powered on for a long time, which affects the uniformity of electroplating, especially for workpieces with high thickness uniformity such as battery cells, the electroplating quality cannot be guaranteed.

[0056] The above-mentioned electroplating equipment is suitable for allowing the plating solution to circulate in the plating tank 101 and the auxiliary tank 102 of the box 1 under the drive of the driving structure 3. Within the electroplating range that can produce a coating, the higher circulation speed and circulation flow of the plating solution help to increase the current density and achieve a better film-forming effect; the part of the bubbling structure 4 formed with a plurality of air outlet holes 402 is immersed in the plating solution, and after the circulation of the plating solution is stable, a gaseous medium is introduced from the air inlet 401 of the bubbling structure 4, and the plating solution is stirred by the gaseous medium; by providing the plating tank 101 and the auxiliary tank 102, as well as the bubbling structure 4, the plating solution is fully stirred while circulating, avoiding ion deposition, increasing the current density of the plating solution, enhancing the uniformity of the coating, and improving the plating quality of the workpiece to be plated, i.e., the battery cell.

[0057] Specifically, the box body 1 is formed with a plating tank 101 and an auxiliary tank 102 through a partition. The volume of the auxiliary tank 102 is smaller than that of the plating tank 101 and is located in front of the plating tank 101.

The driving structure 3 is a pump group structure in this embodiment, which provides power for the flow of the plating solution. The pump group structure includes a circulation pump, a frequency converter and a regulating valve. The frequency converter controls and adjusts the circulation speed of the circulation pump, and the regulating valve controls the circulation flow rate by adjusting the opening and closing degree.

[0058] Specifically, in the above-mentioned electroplating equipment, the gaseous medium passing through the bubbling structure 4 is nitrogen or compressed air, which is safe and stable as a gaseous power source. Nitrogen or compressed air with a certain pressure and flow rate enters the electroplating solution in the form of bubbles through the air outlet 402 of the bubbling structure 4. The bubbles drive and strengthen the flow of the electroplating solution around them during the upward movement, thereby enhancing the uniformity of the electroplating solution.

[0059] like Figure 6 As shown, the connection structure 2 in this embodiment includes: a liquid inlet pipe 201 and a liquid return pipe 202, one end of the liquid inlet pipe 201 is connected to the auxiliary tank 102, and the other end is connected to the electroplating tank 101, and a driving structure 3 is arranged on the liquid inlet pipe 201 to drive the electroplating liquid in the auxiliary tank 102 to pass into the electroplating tank 101; one end of the liquid return pipe 202 is connected to the bottom end of the electroplating tank 101, and the other end is connected to the auxiliary tank 102.

At the same time, the protective plates 6 can limit the particles from settling at the bottom of the gap space, avoiding affecting the uniformity of the plating solution in the space between the two protective plates 6.

The mounting ends of the heating element 10 and the temperature detection element 11 are fixed on the box body 1, and the execution ends are extended into the electroplating liquid in the auxiliary tank 102, and are suitable for being electrically connected to the control device 12.

[0074] Specifically, the heating element 10 is an electric heater, the mounting end of the electric heater is fixed on the box 1, and the heating tube is passed into the plating liquid in the auxiliary tank 102 as the execution end to heat the plating liquid. The increase in the temperature of the plating liquid can accelerate the diffusion, reduce the concentration polarization, and increase the upper limit of the current density, thereby improving the production efficiency; at the same time, the mounting end of the temperature detection element 11 is also fixed on the box 1, and the probe is inserted into the plating liquid as the execution end to monitor the temperature of the plating liquid. First, turn on the heating element 10. When the temperature of the plating liquid reaches the set temperature, the temperature detection element 11 transmits the information to the control device 12, and the control device 12 receives the signal and stops the heating of the heating element 10. Compared with directly heating the plating liquid in the plating tank 101, heating in the auxiliary tank 102 with a smaller volume can reduce the damage to the various components in the plating tank 101, extend the service life of the electroplating equipment, and have higher heating efficiency, ensure the consistency of the plating liquid temperature, and further improve the efficiency and quality of electroplating.

[0075] In addition, the electroplating equipment of this embodiment is fixed with a control device 12 on the box 1 to realize automatic control of the electroplating equipment and enhance work efficiency. The control device 12 includes a control button, a display structure and an internal control module, and the control module can realize temperature control, control of the adjustment component 8, circulation control of the electroplating solution, bubbling control, start-stop control and abnormal alarm, etc. At the same time, these information states are indicated by a three-color light 13, for example, the green color of the three-color light 13 is used to indicate that the process is proceeding normally, the yellow color indicates that the process is finished, and the red color indicates that the process is abnormal or has a fault, etc.

[0076] The working process of the electroplating equipment of the utility model is as follows:

[0077] S1: First, click the control button to start the plating solution circulation. The plating solution is pressurized from the auxiliary tank 102 through the bottom liquid inlet pipe 201 and the driving structure 3, and is evenly sprayed out from the spray hole 5021 in the plating tank 101, and then flows back to the auxiliary tank 102 from the bottom liquid return pipe 202; at the same time, the bubbling structure 4 is turned on, and the gaseous medium enters the bubbling structure 4 from the air inlet 401, and is discharged from the plurality of air outlets 402 in the bubbling structure 4 into the plating solution in the plating tank 101, so as to evenly plate the plating solution;

[0078] S2: The lifting structure 801 drives the workpiece to be plated to descend to the coating position in the electroplating tank 101. At this time, the sliding member 8031 ​​is accurately inserted into the card slot of the electroplating clamping structure 802. After the second detection member 903 of the structure to be detected 9 senses the signal, it is fed back to the control device 12 to instruct the lifting structure 801 to stop descending and the coating starts.

[0079] S3: The coating timer is started, and the clamping structure 802 moves left and right, forward and backward under the action of the second control structure, and then drives the workpiece to be plated to move left and right, so that more ions are in contact with the workpiece to be plated during the coating process, and the film layer is deposited more evenly;

[0080] S4: When the timer ends, the coating is completed and a feedback signal is given to the lifting structure 801. The lifting structure 801 starts to rise to a predetermined position. The first detection member 902 of the detection structure 9 detects the signal and then feeds it back to the control device 12, giving a yellow light signal and a buzzer signal to the three-color light 13 to prompt the staff that the process is completed. After the process staff removes the workpiece, the next round of coating operation is carried out.

[0081] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
