Description

[Detailed description of the invention] [Summary] This invention is a hanging device consisting of a hanger frame and a hook member for suspending parts to be etched and immersing them in a treatment liquid tank. In order to prevent etching liquid, etc. from dripping onto the parts to be etched through the hook member, the hook member whose one end is fixed to the hanger frame is made of a W-shaped wire rod, and the V-shaped part on the free end side of the hook member is made of a W-shaped wire rod. The part to be etched is hung thereon, and the cleaning liquid etc. adhering to the hanger frame is made to drip from the V-shaped portion on the fixed end side.

[Industrial Application Field] This invention relates to a hanging tool for parts to be etched, and more specifically to a hanging tool structure that prevents cleaning liquid, etc. attached to the hanger frame from dripping onto the parts to be etched. .

When photo-etching a large number of processed parts, the parts to be etched are suspended on a hanging device, and the hanging device is attached to a means of transport and placed in a cleaning solution tank,
A method is adopted in which the material is moved between each process such as a drying chamber, a resist liquid bath, a drying chamber, and an etching liquid bath.

[Conventional technology]

As shown in FIG. 3, the conventional device for hanging parts to be etched has two U-shaped hook fittings 12 fixed to the upper frame portion of a frame-shaped hanger 11 and one spring hook 13 fixed to the lower frame portion. It is a structure.

When suspending a sheet-like part 21 to be etched from this hanging tool, holes are formed at the upper and lower ends of the part, respectively, and the hook fitting 12 is placed in the upper end hole, and the hook metal fitting 12 is placed in the lower end hole. The spring hooks 13 are hooked and hung. After hanging the parts, the hooking arm 14 provided integrally with the upper frame of the hanger 11 is attached to the transportation means 31.
and move it to the cleaning solution tank, drying room, and other processes.

[Problem that the invention attempts to solve]

However, in the conventional hanging device, during the process of moving the part to be etched 21 to the next drying process after immersing it in a cleaning liquid tank, a resist liquid tank, etc., the cleaning liquid etc. attached to the hanger 11 may be transferred through the hook fitting 12. There is a phenomenon in which the etching flow occurs in the part 21 to be etched. The dripping part A of the part to be etched has a different surface condition from other parts, that is, the contaminants attached to the hanger, etc. are also flowing, and the degree of contamination is high, causing problems such as poor adhesion of the resist. .

In view of the above-mentioned conventional situation, the object of this invention is to provide a hanging tool having a structure that prevents cleaning liquid etc. adhering to the hanger frame from dripping onto the parts to be etched.

[Means for solving problems]

In order to achieve the above object, this invention consists of a hook member 41 for suspending the part to be etched 21, as shown in FIG. The V-shaped part 43 on the fixed end side, which is used as a hook part for the part to be etched and is fixed to the hanger frame 11, is used as a drip part for cleaning liquid or the like adhering to the hanger frame.

[Effect]

In the W-shaped hook member 41, the flow of the cleaning liquid etc. attached to the hanger frame 11 is caused by the V on the fixed end side.
It stays at the character part 43 and hangs down at this point. Therefore, the cleaning liquid etc. adhering to the hanger frame will not flow to the part to be etched via the hanging tool. It should be noted that although the cleaning liquid etc. adheres to the V-shaped portion 42 on the free end side, the amount is extremely small compared to the amount of adhesion to the hanger frame 11, so there is no problem.

[Embodiment] An embodiment of this invention will be described below with reference to a perspective view of the main parts in FIG. 2.

In Figure 2, 11 is a hanger frame made of stainless steel (SUS304), 21 is a part to be etched, and 41 is a stainless steel (SUS304) wire rod.
This is a hook member for the part to be etched, which is formed into a letter shape. One end of the hook member 41 is attached to the hanger frame 1
The V-shaped part 43 on the fixed end side has a tapered shape so that cleaning liquid etc. can easily drip down, and the V-shaped part 4 on the free end side is fixed to the upper frame part of 1 by welding.
2 has a U-shaped shape so that various parts to be etched can be hung thereon. Although not shown in the drawings, the hanger frame 11 is provided with a hanging arm on the upper frame and a spring hook on the lower frame, as in the conventional example.

[Effect of idea]

As is clear from the above explanation, the hanging tool of this invention does not allow the cleaning liquid attached to the hanger frame to flow onto the parts to be etched, so it is useful for practical purposes such as improving the adhesion of the resist to the parts to be etched. be effective.
