Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a holder for setting a linear sample when performing surface analysis of the linear sample.

[Conventional technology]

When performing surface analysis of a linear sample, such as analyzing the plating layer of a plated metal wire, if the diameter of the linear sample is small, it is likely to bend or break, so the sample should be removed from both ends. Pull it,
It is necessary to maintain a straight line state.

Conventionally, when maintaining a linear state of a linear sample that is relatively small in diameter and easily curved or bent, for example, as shown in FIG. Linear sample 3
1 is held down by a pair of weights 33, 33 attached to the frame 32 so as to be movable up and down, and the transport rollers 30, 3
A linear sample 31 between 0 and 0 is made into a straight line, and the surface is analyzed by an analyzer 34 placed below it.
When measuring multiple positions in the circumferential direction of the linear sample 31, marks are attached to the surface of the linear sample 31, and the linear sample 31 is visually rotated, for example, by 90 degrees based on the marks. There is.

[Problem that the invention attempts to solve]

As described above, conventionally, the linear sample 31 is held down by the weight 33 and the linear sample 31 is fixed by the weight, which causes a problem that the fixing becomes unstable. When measuring multiple positions on the circumferential surface of the linear sample 31, it takes time and effort to mark the linear sample 31, and the measurement positions in the circumferential direction are set by visual inspection based on the marks. Therefore, there is a problem in that it is time-consuming and causes variations in the setting of measurement positions.

In particular, when performing surface analysis of a linear sample 31 for the purpose of, for example, calibrating a plating device, it is necessary to replace several types of linear samples 31 many times, which requires a lot of effort. The distance between each linear sample 31 and the analyzer 34 and the linear sample 3
There is a problem that the reproducibility of the measurement position in the circumferential direction of No. 1 becomes worse.

The present invention was developed to solve the above-mentioned problems, and it is possible to reliably maintain a linear state for any linear sample, and also to measure the circumferential direction of a linear sample. The purpose of this invention is to obtain a holder for a linear sample whose spacing can be made constant.

[Means for solving problems]

In the holder of the present invention, a pair of supports including an insertion hole for a linear sample and a means for fixing the linear sample inserted into the support are rotated to the main body of the holder with the axes of the insertion hole substantially aligned. The support body is slidable in the same direction as the axis of the insertion hole, and includes a moving means for moving the support body in a direction away from the other support body, and the support body is slidable in the same direction as the axis of the insertion hole. The present invention is characterized in that the main body is provided with support rotation angle confirmation means for confirming the rotation angle of the support body in pair with the main body.

[Effect]

To attach a linear sample to this holder, insert the linear sample into each insertion hole of a pair of supports, fix it to each support using a fixing means, and place the linear sample between the supports. The linear sample is made straight by moving the slidable support with its moving means in the direction in which the linear sample is attached and pulled. In this state, the surface of the linear sample is analyzed. When changing the measurement position of the circumferential surface of the linear sample, each support is rotated after confirming the rotation angle using rotation angle confirmation means provided on each support and the main body.

[Effect of idea]

As described above, in the present invention, a linear sample is mounted on a pair of supports in an erected manner, and the supports are moved in the axial direction by a moving means to pull the linear sample into a straight line. The sample can be reliably kept in a straight line state. Since the linear sample is inserted into the insertion hole provided in the pair of supports and fixed to each support, by placing the holder at the measurement position of the analyzer, the wire can be connected to the analyzer. The distance to the shaped sample can always be kept constant, and measurement errors due to differences in the distance can be eliminated.

The measurement position of the linear sample in the circumferential direction is confirmed and set using the rotation angle confirmation means provided on the support and the holder body, so there is no need to take the trouble of marking the linear sample. The measurement positions in the circumferential direction can be set at predetermined intervals, and the reproducibility of the measurement positions in the circumferential direction can be improved.
