Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a microscope observing jig for industrial materials.

[Prior art and its problems] When processing various coatings and layers such as alumite, it is necessary to strictly control whether the coatings or layers have the target generation state or the film thickness / layer thickness. It is practiced to collect a minute sample from a coating or a thin plate having a layer, and observe and measure the film thickness and cross section with a microscope.

In order to obtain the precision of this microscopic observation, it is indispensable to set the film or layer at right angles to the observation surface.
Therefore, a method of embedding and fixing the sample in a transparent synthetic resin has been adopted, but the coating or layer is generally extremely thin on the order of microns, and the base material side is also thin and poor in rigidity,
It is difficult to stand upright at right angles and hold it, and it is displaced by slight vibration or impact until the fixing resin is hardened, so that the minute sample 1 ′ with respect to the observation surface A as shown in FIG.
Were often buried in a slope. As a result, the workability is poor, and not only does it take a lot of time and effort, but a large error (indicating a larger value than the actual value) occurs in the film thickness measurement result, and this error is reflected in actual processing, resulting in a product thicker than the target value. However, the yield of non-defective products was reduced.

Japanese Patent Application Laid-Open No. 60-233530 relates to a microscope observation of a block-shaped sample such as a plastic lens or a magneto-optical disk, and a cardboard cut into a rectangle is attached to the back surface of the trimmed block-shaped sample with a double-sided tape to embed the cardboard together. Although it is proposed to insert and fix it in the device,
Workability is poor, it is not easy to set the sample at a right angle to the observation surface, and if you try to fix it with synthetic resin, the heat of the molten resin will release the mounting and tilt it obliquely or melt it There is a problem in that the agent and the paper as the backing paper adhere to the sample and deteriorate the microscope observation conditions.

Further, Japanese Utility Model Laid-Open No. 55-78936 proposes a molding die for embedding. This prior art is suitable for embedding a sample such as a pin or a rod having a specific diameter. It is difficult to raise or hold a thin thin surface micro sample that has no thickness and is accurate at a right angle, and the mold structure is complicated, and it requires a cutting process after molding, resulting in high cost. There was a problem.

Regarding the sample holder for X-ray diffraction, see
However, this prior art requires a complicated structure and work in which a sample is loosened in a hole of a thin plate and the thin plate is fitted into a hole of a base body. There is a problem in that the jig structure is complicated and the operation is very troublesome because it is necessary to form a step portion that abuts against each other and fix one end of the leaf spring to the sample support base.

[Means for solving problems]

The present invention solves the above-mentioned problems and aims to provide a jig of this kind with a simple structure capable of embedding and fixing a microscopic sample for microscopic observation in resin in an upright state. The place is a jig that is embedded in a synthetic resin together with a thin-walled micro sample for microscopically observing a thin-walled micro sample such as a coating member.
A strip-shaped piece that has a widthwise end face and rises at a right angle to the base surface, and the strip-shaped piece has a pair of curvature sandwiching walls that are inwardly curved to obtain an opening for sandwiching a thin-walled micro sample, and the pair of curvature sandwiching walls. The structure is such that the walls are connected by a curvature connecting portion that constantly urges the opening in the closing direction.

〔Example〕

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

1 to 3 show an embodiment of a microscope observing jig for industrial materials according to the present invention, in which 1 is a thin surface micro sample (hereinafter simply referred to as "micro sample"). The aluminum plate 10 is cut out of an industrial material having a coating 11 such as an alumite film.

Reference numeral 2 denotes a jig according to the present invention, which is made of a band material made of a material having good corrosion resistance and good elasticity such as stainless steel or synthetic resin. The strip has a widthwise end face which rises at a right angle to the base face, and the free end side is inwardly bent in the plate thickness direction to sandwich a pair of curvatures so as to obtain an opening 3 for sandwiching the micro sample 1 in the central portion. Walls 4 and 4 are formed,
The pair of curvature sandwiching walls 4 and 4 are connected by a curvature connecting portion 5 that constantly biases the opening 3 in the same direction.

In the normal state, the curvature sandwiching walls 4, 4 are in contact with each other as shown in FIG. 1, and the ends of the curvature sandwiching walls 4, 4 are extendable bent portions 40, 40 that can be wound along the curvature connecting portion 5. Therefore, it is possible to cope with the thickness of the minute sample 1 in a considerable range.

7 is a fixing resin, and a transparent thermoplastic resin or the like is used.

[Operation of Example]

Since the present invention is configured as described above, when measuring the film thickness of the micro sample 1, the present sample is placed on a horizontal plane such as a table and the micro sample 1 is placed between the pair of curvature sandwiching walls 4 and 4.
Or the opening 3 is opened to insert the micro sample 1 and the end surface of the micro sample 1 is adjusted so as to be in contact with the horizontal surface. Then, the product of the present invention is placed in a pan or the like, and the molten resin is poured and solidified. A pair of curvature sandwiching walls 4 and 4 are extended bent portions 4
Since 0 and 40 are curved along the curvature connecting wall 5,
When the micro sample 1 is inserted, the extension bent portions 40, 40 are naturally wound and moved to form the opening 3. Also, when the opening 3 is made in advance and the micro sample 1 is sandwiched, it can be easily carried out by inserting a fingertip or the like into the hollow portions of the pair of curvature sandwiching walls 4 and 4 and expanding it to the left and right.

In the present invention, the curvature connecting portion 5 urges the pair of curvature sandwiching walls 4 and 4 toward the closing side, and the pair of curvature sandwiching walls 4 and 4 is internally curved, so that the spring itself has a good spring property. Therefore, even if the micro sample 1 is thin and is not stiff, the micro sample 1 is firmly clamped over the entire length in the width direction, and if the thickness of the micro sample 1 changes, the extended bent portions 40, 40 are wound along the curvature connecting wall 5. It is possible to freely respond to changes in thickness. Also,
Since the sandwiching walls 4 and 4 are rounded and there is no sharpness of the opening like a triangular clip, even if the micro sample 1 comes into contact when the micro sample 1 is sandwiched, it is not scratched and the edge is locally localized. Since no pressure is applied, the micro sample 1 is not unduly pressed and damaged.

Further, the mounting area constituted by the pair of curvature sandwiching walls 4, 4 and the end faces of the curvature connecting portion 5 connecting them is wide, and the fixing resin 7 is solidified because it is stably erected at a right angle from the horizontal plane. Until then, the micro sample 1 is kept at a right angle to the observation surface A and is fixed as it is.

The whole micro sample 1 may be embedded in the fixing resin 7,
You may embed only the required range. Since the jig 2 of the present invention is composed of a strip and rises in the width direction, the flow of the fixing resin 7 cannot be obstructed.

After that, as in the conventional case, the whole B embedded with the fixing resin 7 may be placed on the stage of the microscope 8 or the stage 9 as shown in FIG. 4 and observed and measured by the eyepiece lens 12. In this case, Since the sample 1 is accurately erected on the observation surface A, the thickness of the coating film 11 can be accurately measured. After measurement, the product can be easily taken out by heating the resin and reused.

When the product of the present invention is made of a synthetic resin having a color different from that of the micro sample, the film and the like stand out due to the difference in tint, so that the thickness and the like can be clearly observed and measured.

[Effect of device]

According to the present invention described above, in the case of a jig which is embedded in a synthetic resin together with a thin-walled surface micro sample for microscopic observation of a thin-walled surface micro sample such as a coating member, the jig has a widthwise end face at a right angle to the base surface. And a pair of curvature sandwiching walls 4 and 4 inwardly curved so as to obtain an opening 3 for sandwiching the thin surface micro sample 1, and the pair of curvature sandwiching walls 4 and 4 are formed. Are connected by a curvature connecting portion 5 that always urges the opening 3 in the closing direction, so that a thin, thin, flat sheet of various thicknesses can be held without being scratched, and a synthetic resin for embedding can be held. Without disturbing the flow of
Even when vibration is applied until the synthetic resin is solidified, it can be embedded while holding a stable and right-angled state accurately to the base surface, and it is possible to perform highly accurate thickness measurement of thin-walled microsamples. . Moreover, since the structure is simple and the distance between the opening 3 and the curvature connecting portion 5 can be shortened, the structure can be made compact, and the manufacturing process can be performed without pressing, so that the manufacturing cost can be reduced. The excellent effect of is obtained.
