Description

A hardware surface electroplating device

Technical Field

The utility model relates to the technical field of electroplating processing, in particular to a hardware surface electroplating device.

Background technique

Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. In order to prevent the metal oxidation (such as rust) of hardware, improve its wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance its appearance, a thin layer of other metals or alloys is usually plated on its surface, which is called electroplating.

The electroplating process is to use the base metal to be plated as the cathode in a salt solution containing the pre-plated metal, and through electrolysis, the cations of the pre-plated metal in the plating solution are deposited on the surface of the base metal to form a plating layer.

In the prior art electroplating method, when a clamping mechanism is used to clamp the workpiece for electroplating, the clamped portion of the workpiece cannot contact the electroplating solution, resulting in uneven electroplating. The workpiece needs to be adjusted and clamped before secondary electroplating.

In addition, when the electroplated workpiece is put into the electroplating solution, some bubbles are sometimes easily attached to the surface. During the electroplating process, since the bubble area is not conductive, no metal deposition can be obtained, and pits will be formed, resulting in uneven electroplating. Since the electroplated workpiece has high current areas and low current areas, the current density is inconsistent, which can easily cause electroplating defects such as burning, whitening, and color difference, thereby reducing the electroplating qualification rate, increasing defective products, and increasing production costs.

There is currently a lack of comprehensive improvement devices for the above-mentioned situations that lead to uneven electroplating.

Embodiment: Please refer to Figures 1-2, a hardware surface electroplating device includes an electroplating box 1, a support frame 2, a lifting mechanism 3, a clamping mechanism 4, a support plate 44 and an impeller 5. The horizontal plate of the support frame 2 is located above the electroplating box 1, and the lifting mechanism 3 is arranged on the horizontal plate. The lifting mechanism 3 includes a driving device 31, a traction frame 34 and a guide rod 32. The driving device 31 is fixedly connected to the upper surface of the horizontal plate, and its output end penetrates the horizontal plate downward and the end is fixedly connected to the traction frame 34. The two ends of the traction frame 34 are respectively fixedly connected with guide rods 32, and the guide rods 32 penetrate the horizontal plate upward and are in clearance with the sleeve 33 arranged on the horizontal plate. The lifting mechanism 3 enables the clamping mechanism 4 and the support plate 44 to move up and down. The driving device 31 of the lifting mechanism 3 is started, and the driving device 31 drives the traction frame 34 to move up and down through its output end, thereby driving the clamping mechanism 4 and the support plate 44 to move up and down. The clamping mechanism 4 is arranged below the lifting mechanism 3, and the support plate 44 is located below the clamping mechanism 4. The guide rod 32 prevents the traction frame 34 from rotating left and right and forward and backward during the lifting process.

The clamping mechanism 4 includes a moving block 42, a motor 41, and a clamping plate 43. The moving block 42 is fixedly connected to the traction frame 34 of the lifting mechanism 3. The motor 41 is fixedly connected to one side of the moving block 42. The output shaft of the motor 41 is fixedly connected to a long rod. The upper surface of the moving block 42 is provided with a through groove that runs through the upper and lower surfaces. The long rod penetrates the entire moving block 42 and is rotatably connected to the moving block 42 through a bearing. The clamping plate 43 is provided with two pieces and is connected to the external thread of the long rod. The clamping plate 43 is located in the through groove and is slidably connected to the through groove. In this embodiment, the two side walls of the through groove are provided with a slide groove, and the clamping plate 43 is also provided with a protrusion. The clamping plate 43 is slidably connected to the slide groove through the protrusion. The setting of the protrusion prevents the clamping plate 43 from rotating around the long rod. The part of the long rod located in the through groove is provided with two sections of threads with opposite rotation directions, which are respectively matched with the two clamping plates 43 threads. When the motor 41 is started, the output shaft of the motor 41 drives the long rod to rotate around its axis. Since the clamping plate 43 is connected to the external thread of the long rod, the clamping plate 43 will move along the axis accordingly. Since the two sections of threads on the long rod that are respectively connected to the two clamping plates 43 have opposite rotation directions, the two clamping plates 43 will move closer or apart when the long rod rotates. The clamping plate 43 can be controlled to clamp or release the hardware to be plated by changing the rotation direction of the output shaft of the motor 41. The clamping mechanism 4 is connected with wires, specifically, the two clamping plates 43 are connected with wires, and the wires energize the two clamping plates 43.

In this embodiment, the connecting pipe fixed to the lower surface of the moving block 42 is connected to the lower surface of the support plate 44. The connecting pipe is provided with an electric wire, and the electric wire is used to energize the support plate 44. A protective fence 45 is also provided on the support plate 44. The length of the support plate 44 is greater than the maximum distance between the two clamping plates 43. When the clamping plate 43 releases the hardware, the hardware will fall on the support plate 44, and the protective fence 45 prevents the hardware from falling out of the support plate 44.

An inner side wall of the electroplating box 1 parallel to the horizontal plate of the support frame 2 is provided with an impeller 5, and the impeller 5 is powered by a power device fixed to a corresponding position on the outer side of the side wall. When the power device is started, the impeller 5 rotates, driving the electroplating liquid to flow. Since the impeller 5 faces the clamping mechanism 4 and the support plate 44, the electroplating liquid forms a water flow that impacts the clamping mechanism 4 and the support plate 44. By controlling the power of the impeller 5 to a suitable size, bubbles on the surface of the hardware can be removed.

Working principle of this embodiment: This embodiment provides a hardware surface electroplating device, including an electroplating box 1, a support frame 2, a lifting mechanism 3, a clamping mechanism 4, a support plate 44 and an impeller 5. Among them, the lifting mechanism 3 controls the lifting and lowering movement of the clamping mechanism 4 and the support plate 44, and the clamping mechanism 4 can clamp or release the hardware. The specific clamping position is the left and right sides of the hardware. When the hardware is released, it will fall into the support plate 44 below. At this time, the bottom surface of the hardware is in contact with the support plate 44, and the two clamping plates 43 and the support plate 44 that clamp the hardware are energized. The impeller 5 can make the electroplating liquid form a water flow toward the clamping mechanism 4 and the support plate 44 to remove bubbles on the surface of the hardware. The specific working process is as follows: start the motor 41 of the clamping mechanism 4 so that the clamping plate 43 clamps the left and right sides of the hardware to be transferred, start the power device of the impeller 5 to make the impeller 5 work, start the driving device 31 of the lifting mechanism 3 to make the clamping plate 43 and the supporting plate 44 of the clamping mechanism 4 descend into the electroplating solution, pass current through the clamping plate 43 so that the other surfaces of the hardware except the parts on the left and right sides in contact with the clamping plate 43, including the bottom surface, are electroplated with a metal layer, control the motor 41 of the clamping mechanism 4 so that the clamping plate 43 releases the hardware, and the hardware falls onto the supporting plate 44, the bottom surface of the hardware contacts the supporting plate 44 and the left and right sides are exposed to the electroplating solution, pass current through the supporting plate 44, and under the action of the current, the metal ions in the electroplating solution are deposited on the surface of the hardware to form a coating, and the left and right sides that were not electroplated before are electroplated, and during this period, the impeller 5 keeps working to drive the electroplating solution to eliminate bubbles on the surface of the hardware. After the surfaces of the hardware parts are coated with the plating layer, the lifting mechanism 3 is controlled to make the clamping plate 43 and the supporting plate 44 of the clamping mechanism 4 rise up and leave the liquid surface, and the hardware parts that have completed the electroplating operation in the supporting plate 44 are collected.
