Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, an apparatus for measuring a deformation amount of a product using a rotatable arc-shaped camera frame according to a preferred embodiment of the present invention and a method of measuring deformation amount using the same will be described in detail.

First, in the case of photographing using the arc-shaped frame for measuring the amount of deformation according to the present invention, the photographing is performed according to the automated equipment at regular intervals at a precise distance. 1 and 2 below show this embodiment.

1 and 2 are schematic diagrams showing a deformation amount measuring apparatus of a product according to an embodiment of the present invention.

1 and 2, the target product 110 for deformation measurement is fixed on the pedestal 100.

Next, a horizontal frame 120 is formed along the horizontal plane of the pedestal 100. At this time, the horizontal frame 120 is provided in the form of a linear camera jig, it is preferable to have a length as long as the distance for measuring the deformation amount.

Therefore, when the camera is fixed to the horizontal frame 120 according to the present invention it is possible to shoot 360 ° to the side of the product at a desired distance.

In addition, as long as the horizontal frame 120 according to the present invention can be rotated around the target product 110, any shape may be used. As an example, a disk-shaped frame as shown in FIG. However, hereinafter, description will be made based on a linear frame structure.

Next, an arc-shaped frame 125 is provided that is fixed to the end of the horizontal frame 120. At this time, the arc length of the arc frame 125 may be any length if it is equal to or greater than a quarter of the arc, but for simplicity of the equipment, the arc frame 120 corresponding to the quarter of the arc is used. desirable.

Such arc-shaped frame 125 exhibits a hemispherical trajectory according to the rotation of the horizontal frame 120.

Therefore, according to the combination of the horizontal frame 120 and the arc-shaped frame 125, any latitude and longitude position can be easily photographed.

In particular, FIG. 1 illustrates an embodiment in which the camera unit 130 is photographed while moving along the hardness of the hemisphere determined by the horizontal frame 120, and FIG. 2 is within a latitude range determined by the movement of the camera unit 130. In the following example, the horizontal frame 120 moves.

Next, Figure 3 is a schematic diagram showing a method of measuring the deformation amount of the product according to an embodiment of the present invention.

In FIG. 3, the horizontal frame 120 and the arc-shaped frame 125 illustrated in FIG. 1 or 2 are omitted.

Referring to FIG. 3, it can be seen that the camera unit 230 photographs the plane 210a, the oblique plane 210a + 210b, and the side surface 210b of the product 210 while moving along the arc frame.

In this case, if the horizontal frame is rotated 360 ° after fixing the camera unit 230 at the photographing position of the isometric plane 210a + 210b, the photographing can be taken at a uniform focal length along the same latitude.

In the past, when a worker shoots a product for measuring the deformation of the product, the reliability of the molding analysis data varies greatly according to the operator's shooting technology. Manpower consumption was high.

In addition, since the operator cannot remember all the errors, it was difficult to accurately focus and shoot with the same distance from the same location when re-shooting.

However, in the present invention, the photographing is performed according to the exact latitude and longitude as shown in FIGS.

Next, as a strain measuring device for implementing the above method, more specific embodiments will be described as shown in Figure 4 and 5 below.

Figure 4 is a schematic diagram showing the deformation amount measuring apparatus of the product according to another embodiment of the present invention.

4 illustrates a structure in which an arc frame 325 is fixed to an edge portion of a linear horizontal frame 320, and the horizontal frame is formed by a rotation axis 310 coinciding with the central axis of the product to be measured 330. The structure with the rotary motor 300 to rotate 320 is shown.

At this time, two or more camera units are mounted on the arc-shaped frame 325 to allow simultaneous photographing at various angles with respect to the product to be measured 330. This not only shortens the strain measurement time, but also enables more accurate and accurate measurements.

The illustrated first camera portion 340 and the second camera portion 345 may be moved along the same rail, respectively, or may move along rails parallel to each other.

In addition, the first camera unit 340 and the second camera unit 345 may move along the horizontal frame 320 as well as the arc-shaped frame 325 as necessary.

Thus, each camera portion has rail fixing rollers 350, 355, 360, 365, and laser alignment portions 370, 375 which can be aligned so that the focus of the camera is exactly coincident with the center of the product 330 to be measured. Each).

5 is a schematic view showing an apparatus for measuring deformation of a product according to still another embodiment of the present invention.

5 illustrates a disc-shaped horizontal frame 420 rather than a linear horizontal frame, in which case the horizontal frame 420 is formed in a donut shape surrounding the pedestal 435 on which the product to be measured 430 is placed. .

As described above, when the horizontal frame 420 is formed in a disk shape, the frame movement can be made more stably, and the friction difference 480 is used at the outer side of the horizontal frame 420, not in a manner in which the rotating motor enters the lower part. Since the rotating method can be used, the lower space of the pedestal 435 can be utilized.

In this case, the friction difference 480 may be a method of being driven by the rotary motor 495 having a rotating shaft 490 on the outer surface of the horizontal frame 420, but is not always limited thereto.

In addition, the camera unit 440 schematically shows an electromagnet fixing method. In this case, in detail, rails or other electromagnet devices to which the camera unit 440 is moved should be shown, but they are not shown in detail due to the limitation of the ground. Therefore, the present invention is not limited due to their absence.
