Abstract

The electroplating roller device has an improved structure, which is arranged by using a flat conductive piece, radiating outwardly from the rotating axis of the drum and flatly attached to the inner surface of the drum, thereby greatly increasing the conductive area, so that the plating plating is processed. The more uniform and flat design eliminates the possibility of workpiece collision with the conductive sheet during rolling, avoids damage caused by collision of the workpiece surface, and also avoids damage caused by collision of the conductive sheet.

Description

Electroplating roller device improved structure

The present invention relates to a plating apparatus, and more particularly to an improved structure of a plating drum apparatus which uses a flat conductive sheet and radiates a flat surface on the inside of the drum.

Barrel plating is a very efficient method of plating for a wide variety of types or a large number of workpieces to be plated. Please refer to FIG. 1A , which is a schematic view of a conventional electroplating roller device, which mainly comprises a rotatable drum 71 in which a workpiece to be electroplated is placed and completely immersed in a plating solution. The conductive wire 72 extending into the drum 71 is supplied to supply electric power, and the plating is completed while the drum 71 is rotated while being energized.

In addition, please refer to FIG. 1B , which is a schematic view of another conventional plating drum device, which is similar to the foregoing structure, except that the conductive wire 72 is replaced by the conductive bar 73 disposed transversely in the drum 71. The principle is the same.

However, regardless of the above examples, they all face the same problem. First, since the conductive line 72 and the conductive rod 73 are energized, the power line is unevenly distributed throughout the drum 71. Therefore, uneven plating may occur in the workpiece to be plated. Moreover, since both the conductive wire 72 and the conductive bar 73 extend to the inside of the drum 71, it often collides with the workpiece during the rotation process, which not only easily causes damage to the surface of the workpiece, but also is easily caused by collision under long-term use. The conductive wire 72 and the conductive bar 73 are damaged. On the other hand, in the case of using the conductive rods 73 in Fig. 1B, since the conductive rods 73 are generally made of stainless steel, the hardness thereof is relatively high, and the contact portions are easily damaged under long-term use, and the conductive efficiency is lowered.

In view of this, the present invention proposes an improved structure of the plating drum device, which not only differs from the prior art structure, but also effectively overcomes various defects thereof; the specific structure and implementation manner will be described in detail below.

The main purpose of the present invention is to provide an improved structure of a plating drum device, which is provided by designing a conductive structure as a flat conductive sheet and arranging a radiation arrangement and flattening on the inner surface of the drum, thereby providing a more uniform electric field and Increase the conductive area, and improve the uniformity and effect of plating.

Another object of the present invention is to provide an improved structure of a plating drum device, which is locked by a fixing screw and a gasket, which not only increases the electrical conductivity and the conductive area, but also is not easy to wear under long-term use, and is also easy to repair and replace. .

In order to achieve the above object, the present invention discloses an improved structure of a plating drum apparatus comprising a side frame and a drum sandwiched therein, and the drum is rotated by a driving gear set, and the side frame has a conductive plate through the conductive The column is electrically connected to the conductive sheet disposed in the drum, and can guide electric power into the drum; wherein the conductive sheet is designed to be flat, and is arranged in a radiation configuration and is flatly attached to the inner surface of the drum, so as to be large Increase the conductive area and provide a more uniform electric field.

On the other hand, the conductive sheet can be locked on the drum by screws and electrically connected with the conductive post, so that not only the conductivity and the conductive area can be increased, but also the repair and replacement are easy.

The purpose of the present invention, the technical content, the features, and the effects achieved by the present invention will be more readily understood by the specific embodiments and the accompanying drawings.

Referring to FIG. 2, a schematic diagram of an improved structure of the plating drum apparatus provided by the embodiment of the present invention is shown.

The improved structure of the plating drum apparatus includes a drum 10, two side frames 21, 22, two gear sets 31, 32, and two conductive plates 41, 42. The drum 10 is generally a hollow cylindrical structure in which a workpiece to be plated is provided, which is placed between the two side frames 21, 22 and can be used by two gear sets 31, 32 installed therebetween. The driving causes the drum 10 to rotate during the electroplating process; and the two conductive plates 41, 42 are disposed on the outer side frames 21, 22 and located outside thereof for guiding electric power into the drum 10 for barrel plating.

For the connection diagram of the conductive plates 41 and 42 and the side frames 21 and 22, please refer to FIG. 3, which only shows the joint structure of the conductive plate 41 and the side frame 21, and the conductive plate 42 and the side of the other side. The structure of the frame 22 is the same, so it is not repeated. The conductive plate 41 is mounted on the side frame 21, and its appearance is similar to a "T" shape or a "D" shape. The upper ends are fixed and electrically connected by the terminals 411, 412, and the lower ends are It can be connected to the inside of the drum 10, and the voltage can be input through the terminals 411 and 412, and the electric power can be input through the conductive plate 41. This part of the power transmission structure and the connection capacity are described in detail later.

When the electric power is guided into the drum 10, it is applied to the plating liquid in the drum 10 by the conductive sheet 12 to complete the plating process. As shown in FIG. 4, it is a schematic view of a fixing plate of the improved structure of the plating drum device provided by the embodiment of the present invention; the conductive sheet 12 is arranged in a radial and flat manner, in other words, in the drum 10 The rotation axis of the side surface extends outwardly and then is disposed flat along the side wall surface of the drum 10. In order to facilitate the provision of the conductive sheet 12, the design of the fixing plate 11 can be provided (the conductive sheet 12 comprises an integral structure including mounting on the fixing plate). The radial portion and all the portions extending along the side wall of the drum 10 are disposed on the side of the drum 10 (one on each side), and the central perforation is the position of the rotational axis of the drum 10, thereby providing the conductive plate 41. The power input (described in detail later), and then the radiation-extending groove having the radiation extending outward is provided for the conductive sheet 12, and then, after being bent along the edge of the drum 10 to the corner, it is flat on the roller The side wall surface (the barrel body) is disposed and connected to the other side. On the other hand, the fixing plate 11 can also provide the protection of the plating liquid corrosion of the conductive sheet 12 and prevent the deposition of the plating metal, and at the same time prevent the workpiece to be plated. Collide the conductive sheet 12; please refer to Figure 2 at the same time. Since the conductive sheet 12 has a flat shape and a radiation flat design, it can provide a more uniform electric field and increase the conductive area, and can improve the uniformity and effect of the plating.

Next, please refer to FIGS. 5A and 5B, which are schematic diagrams of the power transmission structure of the improved structure of the plating drum device provided by the embodiment of the present invention. The end of the conductive plate 41 has a fixing groove 411, and is disposed on the side frame 21 by the core 51. The core 51 includes a core body 511 and a core ring 512, which is convenient for replacement when worn; Then, the conductive column 52 is used to penetrate the side wall of the drum 10, the gear set 31 and the side frame 21 (the core 51), and then the fixing groove 411 of the end of the conductive plate 41 is mounted, and the conductive sheet 12 (the same as above, the conductive sheet 12 contains the whole The structure is fixed to the conductive post 52 by the fixing screw 53 and can be combined with the arrangement of the spacer 54 to not only increase the stability of the joint but also further increase the conductive area. Please pay special attention to this part. This part only shows the structure on one side, the other side is the same structure, and will not be repeated. Therefore, there will be two sets of cores 51, conductive columns 52, fixing screws 53 and spacers. For the purpose of FIG. 5B, only one conductive strip 12 is shown. In order to achieve a uniform electric field, at least two conductive sheets 12 are required, and only one strip is shown to indicate its power conduction state. In addition, in the case of FIG. 5A, the positional relationship between the conductive plate 41, the core 51, the conductive post 52, and the fixing screw 53 and the spacer 54 is mainly shown, so that the structure of the partial plating roller device ( For example, the side frame 21, the gear set 31, the drum 10, etc.) are not shown in this figure.

Therefore, with the above configuration, the external output voltage can be transmitted to the conductive sheet 12 through the conductive plate 41 and the conductive post 52 (or through the fixing screw 53 and the spacer 54), thereby achieving the barrel plating process.

In summary, according to the improved structure of the plating drum device provided by the present invention, the flat and radially disposed conductive sheets can not only provide a more uniform electric field and increase the conductive area, but also improve the uniformity and effect of plating. At the same time, due to the flat configuration, during the rotation process, the workpiece to be plated does not easily collide with the conductive sheet, so that the surface of the workpiece is not damaged, and the chance of the conductive sheet being damaged by the collision and the possibility of the electrode falling off can be reduced. Furthermore, the conductive plate and the conductive column are made of the same material and are locked by screws, which not only increases the conductivity and the conductive area, but also is not easy to wear under long-term use, and is also easy to repair and replace.
