The two illuminators 2; 2 are supported by the support 3 so as to be positioned on a straight line with a distance H therebetween. The support 3 is formed by, for example, two metal rods 3a; 3a.
One of the two illuminators 2; 2 is used as a front end side illuminator 8, and the other is used as a subsequent illuminator 9.

For example, the front side illuminator 8 includes a cover 6 in which both ends of the cylindrical portion 11 are formed in a hemispherical shape 12.
The succeeding illumination device 9 has a configuration including a cover 6 in which one end of the cylindrical portion 11 is formed in a hemispherical shape 12, for example.
In a state where one end of the hemispherical shape 12 of the cover portion 6 of the front side illuminator 8 and one end of the hemispherical shape 12 of the cover portion 6 of the subsequent illuminating device 9 face each other with a predetermined interval H therebetween, By fixing the metal thin bar 3a to the outer surface of the cover 6 of the front side illuminator 8 and the cover 6 of the subsequent illuminator 9 with an adhesive or the like not shown, the front side illuminator 8 and the subsequent illuminator 9 Are supported so as to be positioned on a straight line with an interval H therebetween.
The two metal thin rods 3a; 3a as the support body 3 are fixed to positions 180 ° apart from each other on the cylindrical outer peripheral surface of the cover 6 of the front side lighting device 8 and the subsequent lighting device 9.
In this embodiment, the succeeding illumination tool 9 is formed such that the cylinder length of the cylindrical portion 11 of the cover portion 6 is longer than the length of the cylinder portion 11 of the cover portion 6 of the front side illumination tool 8. The cylindrical portion 11 of the cover 6 of 9 functions as a rod for inserting the head side lighting device 8 and the subsequent lighting device 9 into a lateral hole 28 described later.

Or the state in which electric power is supplied to each of the front side lighting device 8 and the subsequent lighting device 9 is maintained. That is, by operating the power supply selection switch 17, both the head side lighting device 8 and the following lighting device 9 are turned on, or only one of the head side lighting device 8 and the following lighting device 9 is turned on. It is possible to make it. Although not shown, the operation lever of the power supply selection switch 17 protrudes outside the housing of the control device 15, and the contact of the power supply selection switch 17 can be switched by operating this operation lever.

A method for creating an image for burr detection using the illumination device 1 will be described.
As shown in FIG. 2, after the vertical hole 21 is formed by a drill (not shown) from the upper surface 23 of the work 22 to be the molded product 20 toward the inside of the work 22, one of the horizontal holes 24 is one of the work 22. One side surface 25 is formed by drilling so as to reach the vertical hole 21 from the side surface 25 and the other horizontal hole 26 is formed by drilling so as to reach the vertical hole 21 from the other side surface 27 of the workpiece 22. And the other side surface 27 and the molded product 20 in which the vertical hole 21 penetrating the lateral hole 28 from the upper surface 23 and projecting below the lateral hole 28 is crossed with each other. In some cases, a burr 30 is generated at the boundary edge 29 between the vertical hole 21 and the horizontal hole 28.

Therefore, the lighting device 1 is inserted from the front side lighting fixture 8 side through the side hole entrance 24a of one side surface 25, and the boundary edge 29a between the side hole 24 and the vertical hole 21 and the vicinity thereof are opened from the side hole 26 side. The rear portion 31 of the front side illuminating device 8 is positioned at a position where it can be illuminated with light as indicated by a two-dot chain line arrow, and the boundary edge 29b between the other horizontal hole 26 and the vertical hole 21 and the vicinity thereof are horizontally disposed. The front portion 32 of the subsequent illuminator 9 is positioned at a position where it can be illuminated with light from the hole 24 side as indicated by a two-dot chain line arrow.
That is, the head side lighting device 8 and the subsequent lighting device 9 are positioned so as not to be seen when the inside of the vertical hole 21 is viewed from the vertical hole inlet 34. That is, when the inside of the vertical hole 21 is viewed from the vertical hole entrance 34, the portion between the front side lighting fixture 8 and the subsequent lighting fixture 9 can be seen and the front side lighting fixture 8 and the subsequent lighting fixture 9 cannot be seen. The lighting device 1 is positioned.
Therefore, the distance H between the head side lighting fixture 8 and the subsequent lighting fixture 9 in the lighting device 1 is set to a size larger than the opening diameter size of the vertical hole 21.

  Then, by operating the power supply selection switch 17, the state A in which only the head side lighting fixture 8 is turned on, the state B in which both the head side lighting fixture 8 and the subsequent lighting fixture 9 are turned on, and only the subsequent lighting fixture 9 are turned on. When the state C is turned on and the inside of the vertical hole 21 in each state A; B; C is imaged from the vertical hole entrance 34 by using, for example, an area camera 33 as an imaging device, the horizontal hole 28 and the vertical hole intersecting each other. Captured images of the boundary edge 29 with the hole 21 and the vicinity thereof are acquired. Here, since the head side lighting tool 8 and the subsequent lighting tool 9 are positioned so as not to be seen when the inside of the vertical hole 21 is viewed from the vertical hole inlet 34, the inside of the vertical hole 21 is imaged from the vertical hole inlet 34. In this case, an image of the entire bottom of the vertical hole 21 where the front side lighting tool 8 and the subsequent lighting tool 9 are not reflected can be captured without the bottom of the vertical hole 21 being covered with the front side lighting tool 8 and the subsequent lighting tool 9. Therefore, the boundary edge 29 between the horizontal hole 28 and the vertical hole 21 intersecting each other and the entire area near the boundary edge 29 can be imaged, and all burrs generated at the boundary edge 29 between the horizontal hole 28 and the vertical hole 21 intersecting each other can be detected. Becomes easy. In the case of imaging from the vertical hole inlet 34, as shown in FIG. 2, the support 3 is in the way and the boundary edge 29 located under the support 3 and its vicinity cannot be imaged. Each state A; B; C time is imaged in the state, and the inside of the vertical hole 21 in each state A; B; C time is also obtained when the lighting device 1 is rotated, for example, 90 ° about the center of the rod. By capturing an image, it is possible to capture an image of the boundary edge 29 located under the support 3 in the state of FIG. That is, a total of six patterns of captured images are taken into the computer 35 as inspection images and displayed on the screen of an image display device (not shown). The inspector looks at the inspection image displayed on the screen to inspect for burrs.

According to the best mode, the vertical hole 21 formed from the upper surface 23 as the outer surface of the molded product 20 toward the inside and the side hole 25 formed from the side surface 25; 27 as the outer surface of the molded product 20 toward the inner side. In the molded product 20 having a hole structure formed so as to cross each other and penetrate each other, the boundary edge between the vertical hole 21 and the horizontal hole 28 that intersect with each other by the front side lighting tool 8 and the subsequent lighting tool 9 29 and the entire vicinity area thereof can be reliably and clearly illuminated by the front side lighting fixture 8 and the subsequent lighting fixture 9, so that the boundary edge 29 of the vertical hole 21 and the horizontal hole 28 intersecting each other and the whole of the vicinity area can be seen. The number of times of imaging can be reduced, and the presence or absence of burrs 30 remaining on the boundary edge 29 can be easily detected with a small number of captured images. That is, it is possible to easily obtain a captured image of a portion where burrs may occur.
Also, by causing the computer 35 to create an image indicating the absolute value of the difference between the state A image and the state B image and an image indicating the absolute value of the difference between the state C image and the state B image. Thus, it is possible to obtain an image that raises the burr 30 and to easily detect the presence or absence of the burr 30.

Other form 1
Another embodiment 1 of a method for creating an image for burr detection using the illumination device 1 will be described. As shown in FIG. 3, after the vertical hole 21 is formed from the upper surface 23 of the work 22 toward the inside of the work 22 by a drill (not shown), one horizontal hole 24 extends from the one side 25 of the work 22 to the vertical hole. The other side hole 26 is formed by a drill so as to reach the vertical hole 21 from the other side surface 27 of the work 22, so that one side surface 25 and the other side surface 27 are formed. Even in the molded product 20 in which the horizontal hole 28 penetrating through and the vertical hole 21 reaching the horizontal hole 28 from the upper surface 23 is formed, the boundary edge 29 between the vertical hole 21 and the horizontal hole 28 and the vicinity thereof A burr 30 may occur.

  In this case, the illuminating device 1 is inserted from the side luminal entrance 24a of one side surface 25 from the front side illuminating device 8 side, and the front side illuminating device 8 of the illuminating device 1 is directly behind the vertical hole entrance 34 and behind the boundary edge 29. The lighting device 1 is positioned so as to be positioned, and the power supply selection switch 17 is operated to turn on only the head side lighting fixture 8 to turn on the state A. The area camera 33 is used to enter the vertical hole 21 from the vertical hole entrance 34. The captured image of the boundary edge 29 of the horizontal hole 28 and the vertical hole 21 and its vicinity region is acquired. In this case, since the light diffusing portion 7 is formed on the surface of the cover 6 of the front side illuminator 8, the inner surface of the horizontal hole 28 located below (the back side) of the front side illuminator 8 is not imaged. In other words, the entire boundary edge 29 between the horizontal hole 28 and the vertical hole 21 located above and beside the head side lighting tool 8 and the vicinity thereof are illuminated reliably and clearly at once by the diffuse lighting by the head side lighting tool 8. In this state, the image is taken.

According to the other form 1, the horizontal hole 28 which penetrates across the side surface 25 and the side surface 27 as the outer surface of the molded product 20, and the vertical hole 21 which reaches the horizontal hole 28 from the upper surface 23 as the outer surface of the molded product 20, In the molded product 20 having the hole structure made of the front side lighting fixture 8, the boundary edge 29 between the horizontal hole 28 and the vertical hole 21 positioned above and next to the front side lighting fixture 8 and the entire area near the boundary edge 29 are Since it is possible to illuminate surely and clearly at a time and to be imaged at once by the area camera 33, the presence or absence of burrs 30 remaining on the boundary edge 29 can be easily detected by one illumination operation and one captured image. It becomes like this. That is, it is possible to easily obtain a captured image of a portion where burrs may occur.
In addition, when the cover 6 of the head side illuminating device 8 does not include the light diffusing unit 7, the front side illuminating device is configured to irradiate light to the boundary edge 29 between the horizontal hole 28 and the vertical hole 21 and the vicinity thereof. 8, that is, on the opposite side of the irradiation side by the vertical hole entrance 34, that is, when picked up by the area camera 33, the inner wall of the horizontal hole 28 located below the back side of the front side lighting device 8 is used as the background portion of the picked-up image. As a result, the background portion of the captured image interferes with the burr detection test.
However, since the front side illuminator 8 of the illumination device 1 of the present invention includes the light diffusing unit 7 on the surface of the cover 6, the background portion of the burr in the captured image becomes a milky white image by the light diffusing unit 7. A captured image that can easily detect burrs can be obtained.

Other form 2
Another embodiment 2 of a method for creating an image for burr detection using the illumination device 1 will be described. As shown in FIG. 4, after the vertical hole 21 is formed from the upper surface 23 of the work 22 toward the inside of the work 22 by a drill (not shown), one of the horizontal holes 24 extends from the one side 25 of the work 22 to the vertical hole. By forming the horizontal hole 28 with a drill so as to reach 21, the vertical hole 21 extending from the upper surface 23 reaching the vertical hole 21 from one side surface 25 to below the position of the horizontal hole 28 was formed. Also in the molded product 20, a burr 30 may occur at the boundary edge 29 between the vertical hole 21 and the horizontal hole 28.

  In this case, the illuminating device 1 is inserted from the front side illuminator 8 side through the side hole entrance 24a on one side surface 25, and the front end portion of the front side illuminator 8 is positioned near the boundary between the horizontal hole 28 and the vertical hole 21. Let Then, by operating the power supply selection switch 17 and in a state A in which only the front side lighting fixture 8 is turned on, the inside of the vertical hole 21 is imaged from the vertical hole entrance 34 using the area camera 33 and A captured image of a portion of the boundary edge 29 with the vertical hole 21 is acquired. In this case, the reflected light reflected by the inner wall surface 36 of the vertical hole 21 where the illuminating light of the front side illuminator 8 is opposed to the front side illuminator 8 is reflected in the boundary edge 29 between the horizontal hole 28 and the vertical hole 21 and in the vicinity thereof. Illuminate the whole.

  According to another form 2, the vertical hole 21 formed from the upper surface 23 as the outer surface of the molded product 20 toward the inside and the vertical hole 21 formed from the one side surface 25 as the outer surface of the molded product 20 toward the inside are provided. In the molded product 20 having a hole configuration including the horizontal holes 28 that reach 21, the boundary edge 29 between the horizontal holes 28 and the vertical holes 21 and the entire area in the vicinity thereof are securely and at once by the front side lighting device 8. Since it can be clearly illuminated and can be imaged at once by the area camera 33, the presence or absence of the burrs 30 remaining on the boundary edge 29 can be easily detected by one illumination operation and one captured image. That is, a captured image of a portion where the burr 30 may be generated can be easily obtained.

  The illuminating device 1 used in the other embodiment 1 may have a configuration in which the light diffusing portion 7 is formed on the surface of the cover portion 6 only in the portion imaged from the side hole entrance 24a of the front side illuminator 8. Even in such a configuration, the inner surface of the lateral hole 28 positioned below the front side lighting fixture 8 is not imaged. Therefore, even when such a front side lighting fixture 8 is used, The entire boundary edge 29 between the lateral hole 28 and the vertical hole 21 located in the side and the vicinity of the boundary edge 29 can be reliably and clearly illuminated at a time and can be imaged at a time, so that one illumination operation, one captured image Thus, the presence or absence of the burr 30 remaining on the boundary edge 29 can be easily detected. That is, it is possible to easily obtain a captured image of a portion where burrs may occur.

  In the case of the method of the other form 2, since the reflected light illuminates the boundary edge 29 between the horizontal hole 28 and the vertical hole 21 and the entire area near the boundary edge 29, the front side illuminator 8 diffuses light on the surface of the cover 6. You may use the front side lighting fixture 8 which is not provided with the part 7. FIG.
