Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hanger that is attached to a carrier that moves along a processing liquid tank so as to be able to rise and fall, and suspends an object to be processed.

[Prior Art] This type of hanger 1, as illustrated in FIG. , a connection rod 6 equipped with hooks 4, 4 at the upper end of which the lower surface is a locking surface from the position of the power supply seats 3, 3;
A workpiece holding member 8 is secured to the power supply bar 2 by hanging a workpiece hanging arm 7 having a U-shaped upper end. A workpiece W is attached to the workpiece holding member 8 .

Further, as shown in FIGS. 5 and 6, on the rails 9 provided along the processing liquid tank row
is on the shelf. Then, the locking portions 12, 12 of the elevating body 11 of the carrier 10 are attached to the hanger 1.
from below to engage the hooks 4, 4 of the hanger 1.
As the carrier 10 moves, it is transported to a predetermined processing liquid tank y, and the power supply bases 3, 3 are placed on power supply shelves 13, 13 arranged beside the processing liquid tank y. Thereby, the power supply bar 2 is supported horizontally, and the workpiece w suspended from the power supply bar 2 via the work holding member 8 is immersed in the processing liquid tank y. This object to be processed lol
is supplied with power from the power supply shelves 13, 13 via the power supply bases 3, 3 from the power supply bar 2, and electrolytic treatment such as plating treatment is performed in the treatment liquid tank y.

[Problems to be solved by the invention] The above-mentioned hanger 1 is transferred to the carrier 10 and runs over other hangers 1, etc.
In order to perform the required surface treatment corresponding to the object w to be treated, each movement is controlled individually, rather than being moved uniformly and sequentially.

Therefore, when moving, for example, from an etching tank, a plating tank, etc. to the next liquid tank y, the hanger 1 is supported by the carrier 10 and is used to treat the plating liquid (for example, chromic acid liquid) etc. that has adhered to the workpiece w. While dripping liquid 1, it travels passing over other hangers 1 placed on the lower liquid tank y.

For this reason, the processing liquid l is sprinkled on the power supply bar of the hanger 1 placed on the lower liquid tank y.
Processing liquid l adheres.

However, as shown in FIG. 3, the upper and lower surfaces 2a and 2b of the conventional power supply bar 2 are horizontal surfaces.
Therefore, when the processing liquid l adheres to the upper surface 2a,
It cannot flow down and stays on the surface 2a. Therefore, each liquid tank y is stopped for a certain period of time to drain the liquid, but the upper surface 2 of the power supply bar 2
The processing liquid remaining in a cannot always be removed sufficiently. For this reason, the upper and lower surfaces 2a of this power supply bar 2,
The processing liquid adhering to 2b dries and further accumulates,
Eventually, since the oxide in this liquid has insulating properties, a power supply failure may occur, and the electrolytic treatment of the object to be treated w may become impossible or the power supply may become insufficient.

In addition, when washing the power supply bar 2 with water, it is necessary to wash not only the upper surface 2a of the power supply bar 2 but also the lower surface 2a of the power supply bar 2.
Cleaning water also adheres to and stays on b due to surface tension. Since this cleaning water drips onto the object w,
In the drying process, this dripping water may cause stain-like gloss unevenness on the surface of the object to be treated w.

The present invention aims to eliminate the above-mentioned drawbacks of the conventional power supply bar 2 by preventing processing liquid, cleaning water, etc. from remaining on the upper and lower surfaces of the power supply bar 2 using a simple structure.

[Means for Solving the Problems] The present invention is characterized in that liquid draining slopes are formed on the upper and lower surfaces of the power supply bar provided on the hanger that suspends the object to be processed.

[Function] Even if processing liquid, cleaning water, etc. adhere to the upper and lower surfaces of the power supply bar, they will flow down and will not stagnate due to the guiding action of the liquid draining slope.

[Example] An example of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 20 denotes a power supply bar, and gable-shaped draining slopes 21a and 21b are formed on the upper and lower surfaces thereof, slanting in the left-right direction from the ridgeline. Inclination angle θ of the inclined surfaces 21a and 21b
The optimum angle is between 45° and 60°. With this configuration, even if processing liquid, cleaning water, etc. adhere to the upper and lower surfaces of the power supply bar 20, due to the guiding action of the inclined surfaces 21a and 21b, if it is on the upper surface, it will flow down to the side, and if it is on the lower surface, it will flow down to the side. The water flows towards the ridge and is quickly removed.
This prevents liquid from adhering and stagnation due to surface tension, etc.

Further, as shown in FIG. 2, liquid draining inclined surfaces 31a and 31b may be formed on the upper and lower surfaces of the power supply bar 30 in a single-sided manner. This inclination angle θ is also about 45° to 60°.

[Effect of the invention] As clarified by the above explanation, the present invention has sloped surfaces 21a on the upper and lower sides of the power supply bars 20 and 30.
21b, 31a, 31b are formed, even if processing liquid, cleaning water, etc. adhere to the upper and lower surfaces thereof, the guiding action of the inclined surfaces 21a, 21b, 31a, 31b allows the processing liquid to flow down quickly. It has an excellent effect of eliminating problems such as poor power supply due to stagnation and drying, and uneven gloss caused by dripping of cleaning water onto the object to be processed.
