Description

Technical Field

[0001] This invention relates to the field of electroplating, and more particularly to an electroplating method. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. Electroplating can prevent metal oxidation, improve wear resistance, conductivity, reflectivity, corrosion resistance, and enhance aesthetics. The outer layer of many coins is also electroplated. Electroplating is widely used in the electronics industry for depositing conductive metals used in printed circuit boards, connectors, and semiconductor interconnects. Conventional equipment can only deposit a single color of metal coating on the surface of wires when electroplating them, and cannot deposit a multi-colored coating on the surface of the wires. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide an electroplating method, which can plate a spliced ​​color coating on the surface of a wire.

[0004] An electroplating method includes the following steps:

[0005] Step 1: Pass one end of the wire to be processed through the electroplating device and fix it using the winding device;

[0006] Step 2: Add two different colored electroplating solutions to the electroplating apparatus;

[0007] Step 3: Perform the first electroplating treatment on the wire;

[0008] Step 4: Perform a second electroplating treatment on the wire, applying a color-blocking plating layer to the wire surface;

[0009] Step 5: Clean the wires;

[0010] Step Six: Dry the wire;

[0011] Step 7: Rewind the wire.

[0012] The specific operation of the first electroplating is as follows: the wire is intermittently conveyed, and when the wire passes through the electroplating device, the wire is immersed in the electroplating solution of the first color, so that the wire acts as the cathode and the plating metal acts as the anode, and a layer of colored metal plating is plated on the surface of the wire.

[0013] The specific operation of the second electroplating is as follows: continue to convey the wire, and during the wire stop, drip a second color electroplating solution onto a certain range of the wire surface, so that the wire acts as the cathode and the plating metal acts as the anode, and a layer of metal plating with another color is plated on the surface of the wire.

[0014] The wire is made of steel.

[0015] The first electroplating is copper plating on the wire.

[0016] The second electroplating is tin plating on the wire.

[0017] The cleaning process involves rinsing the wire with clean water.

[0018] The electroplating apparatus includes an electroplating tank with a second cavity above it. Multiple limiting rollers, all made of silicone, are rotatably connected inside the electroplating tank. An anode rod is fixedly connected inside the electroplating tank. A conveyor roller is rotatably connected to the upper end of the electroplating tank. A circulation cylinder is fixedly connected to the upper end of the electroplating tank, and an impeller is rotatably connected inside the circulation cylinder. An inlet pipe is fixedly connected to the side wall of the circulation cylinder, with its other end communicating with the second cavity. Multiple outlet pipes are fixedly connected to the front end of the circulation cylinder. Multiple sleeves are fixedly connected to the upper end of the electroplating tank, and multiple nozzles are fixedly connected inside each sleeve. The anode rod and multiple sleeves serve as the anode, and the conveyor roller serves as the cathode. The electroplating apparatus also includes multiple wires. These wires pass through the inside of the electroplating tank and rest on the lower ends of the multiple limiting rollers. The wires also bypass the conveyor roller and pass through the multiple sleeves. Attached Figure Description

[0027] The present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0028] An electroplating method includes the following steps:

[0029] Step 1: Pass one end of the wire to be processed through the electroplating device and fix it using the winding device;

[0030] Step 2: Add two different colored electroplating solutions to the electroplating apparatus;

[0031] Step 3: Perform the first electroplating treatment on the wire;

[0032] Step 4: Perform a second electroplating treatment on the wire, applying a color-blocking plating layer to the wire surface;

[0033] Step 5: Clean the wires;

[0034] Step Six: Dry the wire;

[0035] Step 7: Rewind the wire.

[0036] The specific operation of the first electroplating is as follows: the wire is intermittently conveyed, and when the wire passes through the electroplating device, the wire is immersed in the electroplating solution of the first color, so that the wire acts as the cathode and the plating metal acts as the anode, and a layer of colored metal plating is plated on the surface of the wire.

[0037] The specific operation of the second electroplating is as follows: continue to convey the wire, and during the wire stop, drip a second color electroplating solution onto a certain range of the wire surface, so that the wire acts as the cathode and the plating metal acts as the anode, and a layer of metal plating with another color is plated on the surface of the wire.

[0038] The wire is made of steel.

[0039] The first electroplating is copper plating on the wire.

[0040] The second electroplating is tin plating on the wire.

[0041] The cleaning process involves rinsing the wire with clean water.

[0042] See Figure 6-10 The diagram shows an embodiment of the invention in which a color-coated layer can be deposited on the surface of a wire. Further,

[0043] The electroplating apparatus includes an electroplating tank 101, with a second cavity 102 above the electroplating tank 101. Multiple limiting rollers 104, all made of silicone, are rotatably connected to the electroplating tank 101 via bearings. An anode rod 103 is bolted to the electroplating tank 101. A conveyor roller 201 is rotatably connected to the upper end of the electroplating tank 101 via bearings. A circulation cylinder 301 is bolted to the upper end of the electroplating tank 101. An impeller 302 is rotatably connected to the circulation cylinder 301 via bearings. An inlet pipe 305 is bolted to the side wall of the circulation cylinder 301. The other end is connected to the second cavity 102. The front end of the circulation cylinder 301 is fixedly connected to multiple drain pipes 403 by welding. The upper end of the electroplating tank 101 is fixedly connected to multiple sleeves 401 by bolts. Multiple nozzles 402 are fixedly connected to each sleeve 401 by bolts. The anode rod 103 and multiple sleeves 401 serve as the anode, and the conveyor roller 201 serves as the cathode. The electroplating device also includes multiple wires 105. Multiple wires 105 pass through the inside of the electroplating tank 101 and rest on the lower end of multiple limiting rollers 104 respectively. Multiple wires 105 bypass the conveyor roller 201 and pass through multiple sleeves 401 respectively.

[0044] When using the electroplating equipment, the operator first adds two different colored electroplating solutions to the electroplating tank 101 and the second cavity 102, respectively. Then, by controlling the rotation of the conveyor roller 201, multiple wires 105 are conveyed. During the wire conveying process, the cathode and anode are energized. After the conveyor roller 201 is energized, the multiple wires 105 become conductive, thus acting as cathodes. This allows the multiple wires 105 immersed in the electroplating tank 101 to undergo electroplating treatment, depositing a colored metallic coating on the multiple wires 105. After being conveyed by the conveyor roller 201, they move to the top of the electroplating tank 101. At this time, the circulation cylinder is controlled... The impeller 302 inside 301 rotates, creating a negative pressure inside the circulation cylinder 301. This allows the electroplating solution in the second chamber 102 to be drawn through the inlet pipe 305, allowing the solution to enter the circulation cylinder 301. Then, under the centrifugal force of the impeller 302, the solution is discharged through multiple drain pipes 403. Finally, the solution is discharged through multiple nozzles 402 inside the sleeve 401, dripping onto the surface of the wire. Since the sleeve 401 acts as the anode, it achieves a secondary electroplating effect on the wire surface, resulting in a second color coating on the wire surface within the sleeve 401 area. This achieves the effect of plating a multi-colored coating on the wire.

[0045] During the electroplating process of multiple wires 105, the control conveyor roller 201 is used to intermittently convey the multiple wires 105, so that the multiple wires 105 can pause when passing through the sleeve 401, thus making the boundary between the two colors more obvious.

[0046] See Figure 4-5A schematic diagram of an embodiment of the present invention, which enables the intermittent transmission of multiple wires 105, is shown. Further,

[0047] A gear 202 is fixedly connected to the conveyor roller 201 by a key, and a drive motor 303 is fixedly connected to the circulation drum 301 by bolts. The impeller 302 is fixedly connected to the output shaft of the drive motor 303 by a coupling. An incomplete gear ring 304 is fixedly connected to the impeller 302 by a key, and the incomplete gear ring 304 meshes with the gear 202 for transmission.

[0048] When conveying multiple wires 105, the impeller 302 is driven to rotate by the drive motor 303, so that the impeller 302 circulates the electroplating solution. At the same time, the impeller 302 drives the incomplete gear ring 304 to rotate continuously. When the incomplete gear ring 304 meshes with the gear 202, the gear 202 drives the conveyor roller 201 to convey multiple wires 105. When the incomplete gear ring 304 disengages from the gear 202, the incomplete gear ring 304 and the gear 202 stop conveying multiple wires 105, thereby realizing the function of intermittently conveying multiple wires 105 without separate control.

[0049] See Figure 8 A schematic diagram of an embodiment of the invention for avoiding black scratches on multiple wires 105 is shown, further...

[0050] The upper end of the electroplating tank 101 is fixedly connected to a scraper 203 by bolts, and the scraper 203 is in contact with the conveyor roller 201.

[0051] Workers spray cleaning fluid onto the scraper 203, ensuring that the conveyor roller 201 remains in contact with the scraper 203 during rotation. The scraper 203 cleans the surface of the conveyor roller 201, removing impurities and preventing black scratches from appearing on the multiple wires 105, thereby further improving the electroplating quality of the multiple wires 105.
