Description

[Detailed description of the invention] The present invention is based on a suspension device for an anode seed rod in an internal plating apparatus that inserts and removes an anode seed rod into a through hole of a cylindrical workpiece and performs plating on the circumferential surface of the through hole. The purpose of this device is to ensure that the anode seed rod hangs vertically into the through hole of the object to be treated using a simple structure.

As shown in Japanese Patent Publication No. 47-6081, the anode seed rod in conventional internal plating equipment is suspended by fixing the upper end of the seed rod to a banger that projects almost horizontally above the liquid tank, and suspending the anode seed rod at right angles to the banger. It was made to droop.

However, with such a configuration, the banger may have a slight inclination,
Due to errors in the formation of the anode seed rod mounting portion, the anode seed rod cannot be suspended vertically, and since the seed rod is long, the lower end of the rod is largely deviated.

For this reason, if the through hole of the object to be treated has a small diameter, it may become impossible to insert the anode seed rod into the through hole, or the anode seed rod may be tilted within the through hole, causing the seed rod and the inner surface of the through hole to be inserted. This resulted in problems such as the inability to make the thickness of the plating layer uniform due to uneven distances between the plating layer and the plating layer.

The present invention eliminates the above-mentioned drawbacks, and includes a first banger that moves intermittently in the left and right direction above the liquid tank and moves up and down, and a first banger that is suspended from above the first banger. In a plating apparatus equipped with a second banger suspending an anode seed rod to be inserted into a through hole of a cylindrical workpiece, a suspension ring provided at the upper end of the anode rod is suspended from the second banger. The anode seed rod is hung vertically by supporting it swingably.

An embodiment of the present invention will be described with reference to the accompanying drawings.

5 maintains an upright position between a pair of upper and lower endless endless chinos 4, 4 that run intermittently in the horizontal left-right direction within a pair of rail grooves 3, 3 attached to the main body frame 1 in FIG. The carrier 5 is a carrier fixed at regular intervals, and a bracket 8 with an engaging roller 9 protruding inward is supported on the carrier 5 so as to be freely movable up and down, and the bracket 8 is moved up and down using the guide column 2 of the main body frame 1 as a guide. The engaging roller 9 is supported on the rail 7 of the elevating frame 6, and the bracket 8 is moved up and down within the carrier 5 as the elevating frame 6 moves up and down.

A first banger 10 is projected forward from the bracket 8.

The first banger 10 consists of a rectangular frame through which an anode seed rod 29 is passed, and a second hanger 17 and a storage case 13, which will be described later, are placed on top of the rectangular frame.

The storage casing 13 has widths corresponding to both the left and right sides of the frame-shaped first hanger 10, and is used to stack objects a to be processed in several tiers, each having a through-hole plated on the perforated bottom plate 14. The four corners of the upper part of the first hanger 10 are raised up so as to be almost in contact with the right outer sides of the left and right side surfaces of the first hanger 10, and the bent part 16 of the upper end thereof is hung on the upper surface of the first hanger 10. Stop and hang.

Reference numeral 17 denotes a second hanger that supports the anode seed rod 29 in a hanging manner, and as shown in FIGS. They are connected by vertical rods 20.

A metal fitting 22 that can freely slide and fix is fitted into the horizontal rod 21 of the upper rectangular frame 18, and a horizontal plate 24 in the front and rear direction is fitted to the metal fitting 22.
Attach the hanging piece 23.

An adjustment piece 25 that adjusts and fixes the horizontal plate 24 is attached to the horizontal plate 24, and an engagement through hole 26 (or a hook-shaped engagement groove) is provided in the adjustment piece 25. The adjusting piece 25 and the hook 27 constitute a hanging piece 28.

Reference numeral 29 denotes an anode seed rod, which is hung from the second hanger 17 by hooking a triangular locking ring 30 provided at its upper end to the hook 27 .

The horizontal rod 21 has locking protrusions 21a protruding from its front and rear ends.

Further, on the lower surface of the lower rectangular frame 19, four conductive mounting pieces 31 placed on the first hanger 10 and energized are mounted in a rectangular arrangement, and furthermore, the left and right conductive mounting pieces 31 are electrically connected to the first hanger 10. A gate-shaped conductive plate 33 whose lower end is attached to a pair of conductive plates 32゜32 is connected to the second
One end of a stretchable braided conductor 34 is fixed to the conductive plate 33 of the hanger 17, and the other ends are fixed to the upper circumferential surface of the anode scraper 29. Power is supplied so that the free swinging of the rod 29 is not hindered.

Others 35.35 are anode seed rods 29 after pickling etc.
A pair of front and rear suspension pieces protrude from the front surface of the body frame 1 above the unnecessary liquid tank 36 and support the front and rear locking protrusions 21a, 21a of the horizontal rod 21 of the second hanger 17. When the second hanger 17, which has been raised together with the bracket 8 by the elevating frame 6, is moved forward in the left and right direction by the bracket 8 at the raised position, the locking protrusion 21
Move at21a onto the hanging pieces 35, 35 Waist bracket 8
is lowered toward the next liquid tank along with the lowering of the lifting platform 6, the second hanger 17 and the anode seed rod 29 suspended by the hanger remain suspended by the suspension piece 35.35. I decided to leave it there.

The operation of the above embodiment will be explained.

The anode seed rod 29 is passed from above into the first hanger 10 suspending the storage case 13, the mounting piece 31 is placed on the support piece 11, and the second hanger 17 is suspended from the first hanger 10.

The first hanger 10 is intermittently raised and lowered by the lifting frame 6;
The basic operation consisting of intermittent advancement in the raised position by the carrier 5 is repeated, but the second hanger 17 is stopped above the non-electrolytic treatment tank 36 by the pair of hanging pieces 35° 35, and the first hanger 17 Separate from 10.

When the immersion of the storage case 13 for a predetermined time due to the stoppage of the first hanger 10 is completed and the first hanger 10 is raised,
The anode seed rod 29 connects the upper end of the locking ring 30 to the second hanger 1.
Since it is hung from the hanging piece 28 of No. 7 and hangs vertically under its own weight, it is smoothly inserted into the center of the through hole of the workpiece a rising together with the first hanger 10, and at the same time the second The hanger 17 is supported with the mounting piece 31 in contact with the support piece 11 of the first hanger 10.

As clarified in the above description, the present invention is an internal plating apparatus in which the anode seed rod 29 is inserted into and removed from the through hole of the workpiece a, and the locking ring 30 at the upper end of the anode seed rod 29 is connected to the second The anode seed rod 2 is hung from the hanging piece 28 of the hanger 17 and supported in a swingable manner so that it is suspended vertically by its own gravity.
There is no change in the vertical hanging position of the hole 9, and the object to be treated can be inserted into the center of the hole reliably. This has an excellent effect of preventing the distance from becoming uneven, making the plating thickness uniform, and improving the quality of the plating process.
