Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an apparatus for holding a thin foil to perform a process such as cleaning, and in particular, a thin foil holding apparatus for holding and holding a thin foil in a vertical state, and a hanging treatment for suspending the thin foil holding apparatus. The present invention relates to a hanging thin foil holding device in which tools are combined.
[0002]
[Prior art]
For example, when a thin foil-like workpiece such as a flexible thin foil substrate is washed, it is necessary to pay attention to the following points for holding the workpiece. That is, (a) Both surfaces of the workpiece can be cleaned at once, (b) Ultrasonic waves are used for cleaning, so that nothing can come into contact with the surface of the workpiece, and (c) The workpiece is securely held. And (d) Considering the production amount, a plurality of sheets can be washed at the same time, and can be processed with the same holding structure from washing to drying.
[0003]
Existing cleaning apparatuses for processing such workpieces are manufactured for cleaning circuit boards and other processed parts, and are roughly divided into the following two types. The first is a structure in which the washing tank is divided into a plurality of pieces, and the baskets made of a net or the like are sequentially inserted into and removed from the washing tank. No. 2 has a mechanism in which the work is transported laterally on the conveyor and flows through the cleaning and drying processes.
[0004]
[Problems to be solved by the invention]
Of these, the former, that is, those having a cleaning tank, require storage tools that match the work, such as a net-like box or a rack with slits, and the flexible substrate can be securely contacted with the surrounding rack members. There is no mechanism for holding the material until now, and sufficient cleaning cannot be performed as it is.
[0005]
On the other hand, the latter, that is, conveyor transport, causes the thin foil itself to warp and swell due to the cleaning liquid sprayed from above at the time of cleaning. Can not do it. Further, since the conveyance is performed by the roller, the back surface is not sufficiently cleaned due to the presence of the lower roller in contact with the lower surface of the workpiece, and the transfer of the dirt and scratches are caused by the roller, which is not suitable as a precision cleaning method.
[0006]
The present invention has been made in consideration of the above-described points, and an object of the present invention is to provide a thin foil holding device capable of holding a thin foil-like work in a flat state with both surfaces exposed as much as possible.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention,

As shown in the figure, a pair of frame members 1 and 2 with a U-shape that is downward facing from the front, that is, with a horizontal side at the top and a vertical side hanging from both sides, with the open part below. Are connected to each other by two hinges 3 provided near both ends of the upper horizontal side, and the lower open ends of the frame members 1 and 2 can be opened.
[0009]
And the nail | claw 4 for pinching is provided in the part near the open end of a pair of frame members 1 and 2. As shown in FIG. This nail | claw 4 for pinching is comprised with elastic materials, such as stainless steel, phosphor bronze, beryllium copper, various engineering plastics, for example. And four nail | claws 4 for pinching are provided per one frame member, and a pair of frame members 1 and 2 have the nail | claw 4 for pinching so that it may oppose the position which mutually respond | corresponds. When the first frame member 1 and the second frame member 2 are closed, the sandwiching claws 4 act just like tweezers between the sandwiching claws 4 of both members 1 and 2. A thin foil is sandwiched between them. Since each of the frame members 1 and 2 is provided with four clamping claws 4, four tweezers are formed when the members 1 and 2 are closed. The four tweezers hold the four corners of the thin foil X that is the workpiece.
[0010]
Each of the four tweezers is fixed to the frame members 1 and 2 so that the tips of the tweezers 4 are slightly upward. In this way, the cleaning liquid is prevented from dripping down onto the workpiece X from the nail 4 for pinching. Moreover, each front-end | tip of the nail | claw 4 for pinching is slanting so that a certain angle may be made with respect to a base end part so that a surface may be contacted. As a result, when the pair of frame members 1 and 2 are closed, the workpiece X is reliably held in a flat state by the holding action accompanied by the elasticity of the four tweezers.
[0011]
As a workpiece to be processed, in the case of a metal foil only having a thickness of several μm to several tens of μm, and an insulating material layer on at least one surface of the metal foil, a metal thin film or a circuit wiring pattern It is provided and has flexibility, and in terms of dimensions, it is about several tens of mm square to several hundred mm square.
