The basic principle applied to the inspection screening apparatus of the machine material component of the present invention shown in Figs. 1 to 2 will be described together with Figs.

The principle of the inspection and screening method applied to the inspection screening apparatus of the machine material parts of the present invention will be described.

In order to inspect the entire surface of the machine material component of the present invention, the optical inspection selection method of the machine material component of the present invention is shown in Figures 3 to 4,

A feeding carousel (10) mounted on the frame (1) and simultaneously performing idle rotation is pivotally driven by an AC geared motor (M) or the like about the axis center (C). do.

On the inner side of the feeding carousel 10 described above of the frame 1, a pair of one or more reflective image concave lenses M1 and M2 arranged in a row at the inspection position P are fixedly installed with a reflector upright. A single optical inspection camera CM is provided outside the feeding carousel 10 with respect to the measurement line L formed by the image concave lenses M1 and M2. In addition, BL is a light source body (Back Light Unit) for providing a light source in addition to such an optical arrangement, it can be applied to various kinds of light source body.

As the optical inspection camera CM, an optical camera of various resolutions for photographing a conventional image may be used.

The feeding carousel 10 has a plurality of inserts for receiving the inspection object I, which is a mechanical material part supplied by the feeder 50, in the circumferential direction, and also revolves as a driving means such as a stepping motor. By rotating and feeding the upper body I, the inspection object I is fed to the center of the optical inspection camera CM and the reflective image concave lenses M1 and M2.

As the feeding carousel 10 is shown in FIG.

A feeding ring 11 disposed at equal intervals is mounted as an insertion groove in which the feeding groove 16 into which the inspection object I is drawn and fixed to the outer circumference is inserted into the U shape. That is, the feeding groove 16 has an open end of the roughly " U " type and inserts and inserts the inspection object I fed by the feeder 50 one by one in a slide manner or the like.

The inspection and screening method employed in the inspection and sorting apparatus of the machine material parts of the present invention having such a configuration ,

The inspection object (I) fed into the feeding carousel (10) by the feeder (30) is fixed to the feeding carousel (10) and rotates about the axis center (C) while the optical inspection camera (CM) Is installed and the reflecting image concave lenses M1 and M2 reach the inspection position P where the excretion lens is disposed, the optical inspection camera CM is a real image (G1) of the inspection object I in the center by electrical signal manipulation. )and,

The reflection images G2 and G3 at different angles on the rear surface of the inspection object I formed by the reflection image concave lenses M1 and M2 are simultaneously captured to be received as the inspection screen IM.

Control images (not shown) of the three (the number of images can be increased by increasing the number of reflection image concave lenses M1, M2...) The discrimination apparatus compares the image of the standard inspection object (I) already set as a reference programmatically and judges the quality of the machine material parts, which are the inspection object (I), and if it is defective, peels it from the feeding carousel (10) and discharges it. It has a conventional configuration.

The logic and program of such an optical inspection method is already well known in the art and is not described in detail in the present invention and such logic is not included in the scope of the present invention.

Therefore, the inspection screening device of the mechanical component of the present invention includes a single optical inspection camera CM and reflective imaging concave lenses M1 and M2, and the optical inspection camera CM and reflective imaging concave lens. The feeding carousel 10 revolving between (M1, M2) feeds the inspection object (I) while simultaneously capturing a plurality of images obtained by dividing the outer surface of the inspection object (I), thereby enabling front inspection. Will be.

Hereinafter, the inspection screening device (IS) of the mechanical component of the present invention described above as an exemplary configuration in conjunction with Figures 1 to 2, but between the optical inspection camera (CM) and the reflective image concave lenses (M1, M2) If it has a feeding means of the inspection object (I) for feeding a variety of configurations other than the configuration disclosed by way of example in the present invention is of course possible.

The inspection screening device (IS) has an axial frame (2) of roughly cross-section "c" shape, standing upright on a rigid frame (1), and an AC geared motor (M) that is a rapid driving source above the center of the shaft frame. ) Is fixed and mounted so that the shaft S faces downward.

At the end of the shaft shaft S of the AC-type geared motor M, the rotating frame 20, which is a rotating disk-shaped member, is fixed and spaced below the rotating frame 20, and is also connected to the shaft shaft S. The feeding carousel 10 is mounted with the shaft center coincident with the extended shaft.

The feeding carousel 10 is a disk-shaped member having a stepped 10 'downward as shown in the drawing, and the feeding groove 16 into which the inspection object I is inserted and fixed in the outer circumference is roughly U-shaped. As the insertion groove, a feeding ring portion 11 arranged at equal intervals is mounted.

As shown in Fig. 2, the feeding groove 16 has an open end of a U-shaped outline, and inserts and inserts the inspection object I fed by the feeder 50 one by one in a slide manner or the like.

In addition, in the above, preferably, the feeding ring 11 may be detachable with a bolt or the like at the outer circumference of the feeding carrier 10.

This allows the feeding ring portion 11 to be detachable from the feeding carousel 10, and is supplied by varying the size and shape of the feeding groove 16 formed in the feeding ring portion 11. It can also be applied to. That is, by simply replacing the feed ring 11 in accordance with bolts and rivets of different diameters or shapes, it is possible to apply to various kinds of mechanical parts.

As described above, the inner side of the feeding carousel 10,

One or more pairs of reflective image concave lenses M1 and M2 disposed in a line at the inspection position P are fixedly installed with a reflecting mirror standing upright, and the measurement line L formed by the reflective image concave lenses M1 and M2. On the outer side of the feeding carousel 10, a single optical inspection camera CM is installed.

In the above-described configuration, the inspection screening device IS performs an idling of the inspection object I between the optical inspection camera CM and the plurality of reflective imaging concave lenses M1 and M2, and at the inspection position P. Imaging can be performed simultaneously in the real image and the virtual image obtained by dividing the front image of (I), so that the front inspection can be performed.

As a result of the above inspection, if the inspection object (I) is a good product, it is discharged to the good product discharge chute 200, and if it is a defective product, the screen is automatically discharged to the bad product discharge chute 100 as various discharge mechanisms such as a pneumatic cylinder, an arm cylinder, and a cam mechanism. It is configured to be performed simultaneously with the test.

Inspection and selection apparatus for mechanical material parts to be carried out using a single optical camera of the present invention as described above;
