Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating barrel type electroplating apparatus primarily used to process large numbers of electrical components and other small components.

Conventionally, this type of device is known to include a rotating barrel that is immersed in a plating bath on a support frame, and a motor or other drive source that drives the rotating barrel, but in this case, the rotating barrel is It is preferable that it be constructed of a thin plate material, and it is also preferable that it be convertible in case of damage or the like.

The purpose of the present invention is to obtain a device that meets these requirements, and includes a rotating barrel 2, which is immersed in a plating bath, mounted on a support frame 1, and a motor or other drive source for driving the rotating barrel 2. 3, in which the rotary barrel 2 is supported by the support frame 1, an outer circumferential barrel 4, and an inner barrel fitted into the barrel 4 through an opening 5 in the end surface thereof so as to be freely removable and removable. It is composed of a circumferential barrel 6, and a lid member 7 applied to the opening 5 is provided with a rotatable core member 8 at the center thereof, into which a conductive piece 9 on the cathode side guided from the outside is inserted.

The support frame 1 has a pair of left and right side plates 1a, 1a connected to each other by a plurality of horizontal members 1b to form a portable structure as a whole, and the outer barrel 4 is made of a relatively thick plate material. The inner barrel 6 is made of a relatively thin plate material and is provided with numerous shaft holes 6a, and the outer barrel 4 is provided with a plurality of relatively large through holes 4a. An enlarged large diameter portion 4b on the side having the opening 5
and the shaft 4c at the other end of the pair of side plates 1a, 1.
The output shaft 3 of the drive source 3 is rotatably installed horizontally between
Further, the inner peripheral barrel 6 has one end open and a flange 6b on the outer periphery, as shown in FIG.
As clearly shown in FIG. 1, the large diameter portion 4b is fitted into the large diameter portion 4b and supported by the lid member 7 applied from the outside thereof. Note that the core member 8 described above is, for example, the first core member 8.
As shown in the figure, it is formed into a cylindrical body through which the conductive pieces 9 are inserted, or as shown in the fourth figure, it is formed into a disk shape through which a plurality of conductive pieces 9 are inserted. etc. are optional.

The lid member 7 is, for example, of a type that is screwed together with a spiral 7a on the outer periphery as shown in the figure, and is provided with a handle 7b for operation on its outer surface as required.

To explain its operation, electrical parts and other workpieces are housed in an inner barrel 6, and the inner barrel 6 is driven by a drive source 3 via an outer barrel 4 that accommodates the electrical components and other workpieces so as to be able to move in and out. The outer barrel 4 acts to cover and reinforce the inner barrel 6 from the outer periphery, and furthermore, the outer barrel 4 acts to cover and reinforce the inner barrel 6 from the outer periphery. The barrel 6 can be taken out from the outer peripheral barrel 4 through the opening 5 on the end face and replaced with a new one if necessary, and the lid member 7 rotates together with the lid member 7 during its operation. The core member 8 is not involved in this rotation, and thus there is no occurrence of twisting or the like when the conductive piece 9 is involved in the rotation.

In this way, according to the present invention, the rotating barrel 2 is composed of the outer peripheral barrel 4 supported by the support frame 1 and the inner peripheral barrel 6 fitted into the outer peripheral barrel 4 so as to be able to move in and out. Reinforced by the outer barrel 4, this can be made of a relatively thin plate material, and thus a good plating effect can be obtained on the workpiece inside, and in the event of damage or other damage to the workpiece, it can be removed and replaced at will. Furthermore, since the conductive piece 9 is guided by passing through the rotatable core member 8 at the center of the lid member 7, it is not accompanied by the rotation of the core member 8, and there is no damage due to twisting or other causes. has.
