Description
- The present disclosure relates to an electroplating assembly mechanism, and in particular, relates to an electroplating assembly mechanism used for electroplating or electroless plating of many small components.
- Usually, there are two ways of plating, one is hanging plating and the other is barrel plating. Hanging plating is a plating method in which components are mounted on a hanger for plating deposition, and is generally used for plating of large-sized components. For small components that are incapable or unsuitable for hanging, due to factors, such as shapes and sizes, barrel plating is generally used. Barrel plating, also known as roller plating, is to place a certain number of small components in a specific roller, and to deposit various metal or alloy coatings on the surface of the components in an indirect conductive manner in a rolling state of the specific roller, thereby achieve surface protection, decoration, or functional purposes. Compared with the hanging plating, the barrel plating process which the components undergo greatly changes. The hanging plating is performed in a state where the components are separately packaged, and the barrel plating is performed in a state in which the components sometimes gather and sometimes separate. In this process, a mixing cycle of the components is generated. In addition, the hanging plating is performed while the components are completely exposed, and the barrel plating is carried out in a low concentration solution in a closed barrel (although there are holes in the wall). The change in the process the components are plated results in two major defects in the barrel plating, namely the defects caused by the mixing cycle and the structural defects of the barrel plating. The above defects have a serious impact on the production efficiency of the barrel plating and the improvement of the product quality, so that the superiority of the barrel plating cannot be fully exerted.
- Furthermore, in the current barrel plating technique, the roller connects a driving device. After the components to be plated are loaded in the roller, the roller is placed in a plating tank and the driving device is activated, so that the components to be plated are turned over, thereby facilitating the contact of the electroplating solution with the components to produce an electrochemical effect. Plating the surface of needle-like or flaky microelectronic components is usually carried out in a plating roller. There are many kinds of plating rollers in the prior art. Most of the plating rollers are driven by horizontal driving devices. These plating rollers generally have problems of complicated structures, difficulty in solution replacement, low plating efficiency, and high maintenance costs.
- In addition, there is also a plating roller disposed at a lower end of a drive shaft for enabling the electroplating tank provided with the anode to be rotationally driven. The centrifugal force is applied when the plating roller is rotationally driven, so that the electroplating solution flows out from the inside of the plating roller to the outside, and then the electroplating solution flows into the inside from the outside. However, the plating roller is fixed at the lower end of the drive shaft and cannot be shifted and replaced. Therefore, the plating process enabling the automatic shifting and the tank replacement cannot be achieved.
- As a result, it is necessary to provide an electroplating assembly mechanism to solve the problems existing in the conventional technologies, as described above.
- An object of the present disclosure is to provide an electroplating assembly mechanism, wherein the vortex blades are used to form a vortex on the electroplating solution in a circular drum body, so that the electroplating solution is quickly exchanged. The flow direction of the plating solution is stabilized by a wire conductive ring, so that the plating solution may evenly immerse the small components, and the effect of uniform electroplating on the surface of the small components is achieved.
- To achieve the above objects, the present disclosure provides an electroplating assembly mechanism for electroplating a plurality of small components. The electroplating assembly mechanism comprises an electroplating drum configured to carry the small components, wherein the electroplating drum includes a circular drum body, a rotary shaft, an engagement portion, and a plurality of vortex blades, wherein a first end of the rotary shaft is disposed on the circular drum body, the engagement portion is disposed at a bottom of the circular drum body and configured to be driven by a drive, and the vortex blades is disposed at the bottom of the circular drum body.
- In one embodiment of the present disclosure, the electroplating assembly mechanism further comprises a moving rack, the electroplating drum is assembled on the moving rack, and the moving rack comprises a fixing plate, two side plates, two auxiliary rods, and a rotary joint, wherein the two side plates are assembled on two side of the fixing plate, the two auxiliary rods are disposed between the side plates, the circular drum body is located above the auxiliary rods, and the rotary joint is pivotally connected to the fixing plate for assembling with a second end of the rotary shaft.
- In one embodiment of the present disclosure, the fixing plate further comprises two cathode bases arranged on two side of a bottom of the fixing plate, respectively, and used for electrical connection with a cathode ring.
- In one embodiment of the present disclosure, the fixing plate further comprises a cathode wire connected to the two cathode bases for electrical connection with the cathode ring.
- In one embodiment of the present disclosure, the circular drum body includes a base, a surrounding wall, an upper cover, and a cathode ring, wherein the base is assembled with the surrounding wall, the upper cover covers the surrounding wall to form an internal space, the rotary shaft is connected to the upper cover and extends outward from the base, and the cathode ring is disposed in the surrounding wall.
- In one embodiment of the present disclosure, the electroplating drum further comprises a wire conductive ring disposed in the circular drum body and spaced from the surrounding wall.
- In one embodiment of the present disclosure, the electroplating drum further comprises a current transmission layer disposed on a base of the circular drum body.
- In one embodiment of the present disclosure, the circular drum body further comprises a plurality of cathode plates and a plurality of tortuous slopes, wherein the cathode plates and the tortuous slope are alternately arranged on the current transmission layer, and the cathode plate is located between two adjacent tortuous slopes.
- As described above, the cathode ring located on the surrounding wall of the circular drum body may be electrically connected to the two cathode bases through the rotating shaft and the cathode wire. When the electroplating drum starts to rotate to generate centrifugal force, the small components in the circular drum body are driven toward the cathode ring. At the same time, the vortex blades cause the plating solution in the circular drum body to form a vortex, and the plating solution is quickly exchanged.

FIG. 1 andFIG. 2 , theelectroplating drum 3 is configured to carry the small components (not shown), and theelectroplating drum 3 may be assembled on the movingrack 2. Theelectroplating drum 3 includes acircular drum body 31, arotary shaft 32, anengagement portion 33, acurrent transmission layer 34, a wireconductive ring 36, and a plurality ofvortex blades 37, wherein afirst end 321 of therotary shaft 32 is disposed on thecircular drum body 31, theengagement portion 33 is located below thefirst end 321, and thevortex blades 37 are arranged on aplate body 38 at intervals around therotary shaft 32. Furthermore, theengagement portion 33 is disposed at a bottom of thecircular drum body 31, wherein one end surface of thesecond end 322 is shaped like a jaw, and the two auxiliary rods are disposed between theside plates 22 so that thecircular drum body 31 is located above the twoauxiliary rods 24. It should be noted that theengagement portion 33 is used to mount a driver (not shown), and driven by a driving wheel of the driver to rotate. - It should be note that the
current transmission layer 34 is made of titanium metal, titanium plated material or titanium sprayed material. Thecircular drum body 31 is made of plastic material.

Furthermore, theplate body 38 is assembled on thebase 311 so that thevortex blades 37 are located above thebase 311. - According to the above structure, by releasing the
rotary joint 27, thecircular drum body 31 and therotary shaft 32 may be detached from the movingrack 2. When contacting and energizing, the two cathode bases 28 on the two sides of the bottom of thefixing plate 21 may be electrically connected to thecathode ring 314. When thefixing plate 21 is moved away, a power failure is formed. Furthermore, when the rotation of thecathode ring 314 accelerates to a specified speed, the small components (electroplate) in thecircular drum body 31 are closely attached to thecathode ring 314 due to centrifugal force, and are electroplated by supplying power. After a period of time, the power is turned off and thecathode ring 314 is decelerated to a low speed, and the small components (electroplate) in thecircular drum body 31 are mixed due to gravity falling on the bottom of thecircular drum body 31.

At the same time, thevortex blades 37 cause the plating solution in thecircular drum body 31 to form a vortex, and the plating solution is quickly exchanged. The design of the wireconductive ring 36 may stabilize the flow direction of the plating solution, so that the plating solution may evenly immerse the small components, and achieve the effect of uniform electroplating on the surface of the small components. - The present disclosure has been described with preferred embodiments thereof and it is understood that many changes and modifications to the described embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
