Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a Carlo cell (jig) for mounting a workpiece for surface treatment such as plating, and more specifically to a carousel (jig) for mounting a workpiece for surface treatment such as plating. This article will discuss Carlocell, which is suitable for drying treatment.

(Prior Art) Generally, magnetic storage disks use an annular plate made of aluminum or aluminum alloy as the disk material, and the surface of the plate is coated with cobalt niracles and a magnetic medium is formed thereon.

(Problem to be Solved by the Invention) However, in such discs, it is necessary to maintain extremely high plating quality. Therefore, there is a problem in that each disk must be rotated during the plating process without overlapping the disks.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a method in which one end of a rod-shaped support for mounting a workpiece is rotatably attached to a frame, and a rod-shaped support is separated by the frame. It is supported horizontally as a beam, and the frame part with the support end fixed is made of hollow wire to form a liquid-tight chamber inside, and the support is rotated in the cough room! By installing a 11g1M# and inserting the support into the center hole of a large number of disc-shaped workpieces, it is possible to hold a large number of workpieces at intervals by the supports, and at the same time transmit rotation to the workpieces. It is a feature.

(Function) According to the above configuration, the workpieces are moved in the longitudinal direction of the support with respect to the carousel, and the reports are inserted into the center holes of the many workpieces with their unsupported ends leading, thereby allowing the workpieces to be mounted. When the report is removed from the center hole of the workpiece, removal of the workpiece is completed.

In addition, during treatment work, by avoiding rotation of the "C nabot" with the workpiece attached, the workpiece can be rotated to increase contact efficiency with the treatment solution, improving plating quality and shortening treatment time.

Historically, the support drive device is installed in a chamber inside the frame, so the drive device does not come into contact with the processing liquid.

(Example) Figure 1 shows the workpiece W being mounted on the carro cell 1 (jig) and processing 1! I! The vertical cross section shows the state immersed in the electroless plating solution (FIG. 5) in tank T. Workpiece W is magnetic memory f

Both ends are seated on a sheet or the like (not shown) at the upper edge of the bottom of the processing tank. Further, arms 20 protrude upward from near both ends of the frame 18. Each arm 20 is provided with a hook 21 at its upper end. When transporting the loader 1 and the workpiece W by a transport robot (not shown) or the like, the transport robot holds the knock 21 and lifts the loader 1.

The support 2, boss 5, shaft 6, and sprocket 13 are made of an electrically conductive material such as stainless steel, and are electrically connected to the base. A carbon brush 22 is in contact with the end surface of the sprocket 13 on the boss 8 side. ,car··
The bomb brush 22 is connected to a potential detector (not shown). Further, as will be described later, the workpiece W is supported by the support 2 in a conductive state. On the other hand, inside the processing tank T, a standard electrode 23 is provided for detecting the potential of the processing liquid. Therefore, the potential of the workpiece W attached to support 2 is
In addition, the potential of the processing solution in the processing tank 1 is detected by a potential detector via the standard electrode 23, and based on the change in the potential difference between the two, the actual It is possible to detect that plating has started.

The other support 3 has the same structure as the U-boat 2 except that it has a larger diameter, and is driven by a single sprocket 13. ) can be detected via the sprocket 133 fixed to the support 3 and the brush 22.
