Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating, and specifically refers to a rotary electroplating device, which can improve the electroplating efficiency, reduce the overall time required for electroplating, and further reduce the power consumption. Background Art

[0002] Metal electroplating was developed by the British Canning Co. in the 19th century and has since evolved into two major electroplating systems: the rack plating system for large workpieces and the barrel plating system for small workpieces or components.

[0003] In a conventional rack plating system, the object to be plated is placed in the plating solution of an electrolytic cell. In the electrolytic cell, except for the object to be plated and the cathode and anode conductors in the plating solution, there are no other components to form a barrier during the electroplating process, so that metal electroplating can be performed at a high current density.

[0004] The conventional roller plating system device, such as Figure 1 to Figure 2 As shown, a porous electroplating drum 3 is provided in an electrolytic cell 1 having a plating solution 2. The electroplating drum 3 is rotated by a driving device 4. A first space 11 is defined in the electrolytic cell 1, and a second space 31 is defined in the electroplating drum 3. An anode conductor 12 is introduced into the first space 11, thereby defining an anode area A between the first space 11 and the second space 31, and the electroplating drum 3 is used to accommodate an object C to be electroplated, and a cathode conductor 32 is introduced, and is defined as a cathode area B.

[0005] Since the above-mentioned roller plating system device uses a plastic electroplating drum 3 to accommodate the object C to be electroplated, it causes the positive and negative ions in the electroplating solution 2 to have a chemical reaction during the electroplating process, which hinders the flow of the positive and negative ions in the electroplating solution 2 in the electroplating solution 2, thereby seriously reducing the operating current density of the roller plating system device, resulting in a significant decrease in the roller plating efficiency, an increase in the overall time required for electroplating, and an increase in power consumption.

[0006] For example, when the rack plating system is operated at a higher current density, generally about 1 to 5ASD (AMPERE PERSQUARE DECIMEFER), if it is 5ASD (5A / dm 2If the electroplating is carried out at a cathode current density of 0.05-0.1ASD, the metal reduction rate on the cathode workpiece is about 1 micron per minute. However, if the roller plating system is used, the plastic roller will hinder the flow of the plating solution, which seriously reduces the current density during operation. The roller plating system can only be operated at a current density of 0.05-0.1ASD, which reduces the electroplating speed to 12-15 minutes per micron.

[0007] In view of this, the author of the present invention has conducted in-depth research on the problems faced by existing roller plating system devices when in use, and actively sought solutions through years of research and development and manufacturing experience in related industries. After continuous efforts in research and trial production, he finally successfully developed a rotary electroplating device that can overcome the inconvenience and trouble caused by the low electroplating efficiency of existing roller plating devices.

[0037] The utility model is a rotary electroplating device. The accompanying drawings illustrate the specific embodiments of the utility model and its components. All references to the front and back, left and right, top and bottom, upper and lower parts, and horizontal and vertical are only used for the convenience of description, and do not limit the utility model, nor limit its components to any position or spatial direction. The dimensions specified in the drawings and the specification can be changed according to the design and requirements of the specific embodiments of the utility model without leaving the scope of the patent application of the utility model.

[0038] The utility model is a rotary electroplating device. Figure 3 to Figure 4 The invention discloses that a porous electroplating drum 3 is provided in an electrolytic tank 1 having an electroplating solution 2. The electroplating drum 3 is rotated by a driving device 4. A first space 11 is defined in the electrolytic tank 1, and a second space 31 is defined in the electroplating drum 3. An anode conductor 12 is introduced into the first space 11, thereby defining an outer anode area D between the first space 11 and the second space 31. An object to be electroplated E is accommodated in the electroplating drum 3, and a cathode conductor 32 is introduced into the electroplating drum 3, thereby defining an inner cathode area F. Furthermore, the electroplating drum 3 has an openable cover plate 33 for placing the object to be electroplated E, and the cover plate 33 is positioned on the electroplating drum 3 by a fixing member 34;

[0039] Among them, please refer to Figure 5 The electroplating drum 3 is provided with a porous hollow cylinder 5 at the center, and an anode conductor 51 is introduced and combined with it, and is defined as an inner anode area G, and a number of non-passive anode metals 6 can be placed in it. In this embodiment, the hollow cylinder 5 is cylindrical, or a sheet is wound around and combined into a cylindrical shape, and the hollow cylinder 5 is a passive metal. Furthermore, the non-passive anode metal 6 can be nickel, zinc, copper, etc., which are metal materials that can be oxidized due to current conduction during the electroplating process;

[0040] Furthermore, please see Figure 6 A circulation device H for circulating the electrolytic solution 2 is provided on the outer side of the bottom of the electrolytic cell 1. The electrolytic solution 2 in the electrolytic cell 1 is extracted through the circulation device H and then input into the inner anode area G, which can accelerate the redox reaction of the electrolyte 2 to increase the electroplating rate and efficiency.

[0041] Thereby, a rotary electroplating device is formed which can increase the electroplating speed and reduce the consumption of required power.

[0042] Through the above structural design, the utility model is actually used in the state, please refer to Figures 3 to 6 As shown, the cover plate 33 of the electroplating drum 3 is first opened, and the object E to be electroplated is placed in the second space 31, and then the cover plate 33 is positioned on the electroplating drum 3 by the fixing member 34; at this time, the cathode conductor 32 is introduced into the second space 31 of the electroplating drum 3;

[0043] Furthermore, the hollow cylinder 5 can be used to place a number of non-passive anode metals 6, and the anode conductor 51 is introduced to be combined with the hollow cylinder 5. Thus, when starting, the electroplating drum 3 is first placed in the electroplating solution 2 in the electrolytic cell 1, and then the driving device 4 is used to rotate the electroplating drum 3 to perform the electroplating work;

[0044] At this time, through the outer anode area D between the first space 11 and the second space 31, and the inner cathode area F in the electroplating drum 3, the metal of the anode releases electrons after the DC power source is turned on, and the positive ions in the solution are reduced (gain electrons) at the cathode to form an electroplating layer that accumulates on the cathode surface of the electroplating object E;

[0045] Furthermore, the hollow cylinder 5 is provided with an inner anode region G by introducing the anode conductor 51, thereby increasing the redox speed in the electroplating drum 3, improving the electroplating speed of the object E to be electroplated during the electroplating process, and reducing the power consumption. In addition, the electroplating solution 2 in the electrolytic cell 1 is extracted and recycled to the inner anode region G by the circulation device H, thereby accelerating the redox reaction of the electrolyte 2 and increasing the electroplating rate and efficiency.

[0046] Please see again Figure 7 As shown, it is another embodiment of the present invention, which can arrange several rotary electroplating devices in parallel so that each rotary electroplating device can perform different electroplating processes in response to different current densities required for different objects E to be electroplated, thereby increasing the degree of adjustment in production efficiency and meeting different electroplating output requirements.

[0047] Through the above-mentioned design, the utility model has a porous hollow cylinder 5 at the center of the electroplating drum 3, and introduces an anode conductor 51 to be combined with it, so that in the electroplating process, in addition to retaining the original outer anode area D and the inner cathode area F in the electroplating drum 3, after the direct current power supply is turned on, the metal at the anode will release electrons, and the positive ions in the solution will be reduced (gain electrons) into atoms at the cathode and accumulate on the cathode surface of the electroplating object E to maintain a normal redox reaction. The anode conductor 51 is introduced through the hollow cylinder 5 to form an inner anode area G inside, thereby increasing the redox speed in the electroplating drum 3. Due to the addition of the circulation device H, the electroplating speed and efficiency of the electroplating object E during the electroplating process can be further improved, and the power consumption can be reduced.

[0048] Thus, it can be understood that the utility model is a creation with excellent creativity. In addition to effectively solving the problems faced by conventional technologies, it also greatly improves the effectiveness. In addition, there are no identical or similar products created or publicly used in the same technical field. At the same time, it has improved effectiveness. Therefore, the utility model has met the requirements of "novelty" and "progressiveness" for utility model patents, and a utility model patent application is filed in accordance with the law.
