Description

本発明は、成形品の外面と内部とに連続するように形成された孔と孔との境界縁に生じたバリの画像を容易に得るためのバリ検出用照明装置及びバリ検出用の画像の作成方法に関する。   The present invention provides a burr detection illumination device for easily obtaining a burr image formed at a boundary edge between a hole and a hole formed so as to be continuous between an outer surface and an inside of a molded product, and a burr detection image. It relates to the creation method.

成形品に開口された小径孔内のバリを検出するために、小径孔内に光を導くための導光筒を備えた側視鏡が知られている。導光筒の先端には、光ファイバーにより外部から導かれた光を孔の内面に照射するための照明照射口と、光を照射した孔の内面からの反射光を導光筒に導く反射鏡とを備え、反射鏡の反射像を孔の外に設けられたＣＣＤカメラで撮像し、この撮像画像によりバリを検出する。
特開平１０−３０７０１２号 In order to detect burrs in a small-diameter hole opened in a molded product, a side endoscope including a light guide tube for guiding light into the small-diameter hole is known. At the tip of the light guide tube, an illumination irradiation port for irradiating the inner surface of the hole with light guided from the outside by an optical fiber, and a reflecting mirror for guiding the reflected light from the inner surface of the hole irradiated with light to the light guide tube The reflected image of the reflecting mirror is captured by a CCD camera provided outside the hole, and burrs are detected from the captured image.
Japanese Patent Laid-Open No. 10-307012

上述した従来技術では、照明を照射できる範囲及び反射像の得られる範囲が狭いので、小径孔内においてバリの発生している可能性がある部分を照明できるように照明照射口の位置を逐一調整したり、照明した部分の画像を逐一撮像しなければならないので、バリの発生している可能性がある部分の撮像画像を得るための操作や手間が煩雑であるという欠点があった。   In the above-described conventional technology, the range in which illumination can be irradiated and the range in which the reflected image can be obtained is narrow. Therefore, the position of the illumination irradiation port is adjusted step by step so that a portion where a burr may be generated in the small-diameter hole can be illuminated. In addition, since it is necessary to pick up images of the illuminated portion one by one, there is a disadvantage that the operation and labor for obtaining a picked-up image of a portion where burrs may be generated are complicated.

It is formed by affixing a milky white light diffusion sheet.
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.

先頭側照明具８は、例えば、円筒部分１１の両端が半球面状１２に形成された覆部６を備えた構成である。
後続照明具９は、例えば、円筒部分１１の一端が半球面状１２に形成された覆部６を備えた構成である。
先頭側照明具８の覆部６の半球面状１２の一端と後続照明具９の覆部６の半球面状１２の一端とが所定の間隔Ｈを隔てて互いに向き合わされた状態で、２つの金属細棒３ａを先頭側照明具８の覆部６と後続照明具９の覆部６との外面に図外の接着剤などで固定することにより、先頭側照明具８と後続照明具９とが、互いに間隔Ｈを隔てて一直線上に位置するように支持される。
支持体３としての２つの金属細棒３ａ；３ａは、先頭側照明具８及び後続照明具９の覆部６の円筒外周面上において互いに１８０°隔てた位置に固定される。

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 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.

先頭側照明具８のＬＥＤチップ５に接続された図外のリード線と制御装置１５とが電気的に接続され、後続照明具９のＬＥＤチップ５に接続された図外のリード線と制御装置１５とが図外の導線により電気的に接続されたことによって、制御装置１５内に設けられた駆動電源から先頭側照明具８及び後続照明具９に駆動電力が供給される。
制御装置１５は、駆動電源１６と、電源供給選択スイッチ１７とを備え、電源供給選択スイッチ１７が、先頭側照明具８及び後続照明具９のうちの１つに選択的に電力を供給する状態を維持するか、あるいは、先頭側照明具８及び後続照明具９のそれぞれに電力を供給する状態を維持する。すなわち、電源供給選択スイッチ１７を操作することによって、先頭側照明具８と後続照明具９とを共に点灯させたり、先頭側照明具８と後続照明具９のうちのいずれか１つのみを点灯させることが可能である。尚、図示しないが、電源供給選択スイッチ１７の操作レバーは制御装置１５の筐体の外に突出しており、この操作レバーを操作して電源供給選択スイッチ１７の接点を切り替えることができる。 An unillustrated lead wire connected to the LED chip 5 of the front side illuminator 8 and the control device 15 are electrically connected, and an unillustrated lead wire connected to the LED chip 5 of the subsequent illuminator 9 and the control device. 15 is electrically connected to the leading illumination tool 8 and the subsequent illumination tool 9 from a drive power source provided in the control device 15 by being electrically connected to the lead wire 15 via a lead wire (not shown).

照明装置１を用いたバリ検出用の画像の作成方法について説明する。
図２に示すように、縦孔２１が成形品２０となるワーク２２の上面２３からワーク２２の内部に向けて図外のドリルで形成された後に、一方の横孔２４がワーク２２の一方の側面２５から縦孔２１に到達するようにドリルで形成され、他方の横孔２６がワーク２２の他方の側面２７から縦孔２１に到達するようにドリルで形成されることによって、一方の側面２５と他方の側面２７とに跨って貫通する横孔２８と上面２３から横孔２８を貫通して横孔２８の下方に突出する縦孔２１とが形成された成形品２０においては、互いに交差する縦孔２１と横孔２８との境界縁２９にバリ３０が発生する場合がある。 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.

そこで、照明装置１を先頭側照明具８側より一方の側面２５の横孔入口２４ａから挿入し、一方の横孔２４と縦孔２１との境界縁２９ａ及びその近傍領域を横孔２６側から二点鎖線の矢印で示すような光で照明可能な位置に先頭側照明具８の後部３１を位置させ、かつ、他方の横孔２６と縦孔２１との境界縁２９ｂ及びその近傍領域を横孔２４側から二点鎖線の矢印で示すような光で照明可能な位置に後続照明具９の前部３２を位置させる。
つまり、先頭側照明具８及び後続照明具９は、縦孔入口３４から縦孔２１内を見た場合に、見えないように位置される。即ち、縦孔入口３４から縦孔２１内を見た場合に、先頭側照明具８と後続照明具９との間の部分が見えて先頭側照明具８と後続照明具９とが見えないように照明装置１を位置決めする。
よって、照明装置１における先頭側照明具８と後続照明具９との間隔Ｈは、縦孔２１の開口径寸法より大きい寸法に設定される。 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.

そして、電源供給選択スイッチ１７を操作して、先頭側照明具８のみを点灯させた状態Ａ、先頭側照明具８と後続照明具９とを共に点灯させた状態Ｂ、後続照明具９のみを点灯させた状態Ｃとし、撮像装置としての例えばエリアカメラ３３を用いて縦孔入口３４から各状態Ａ；Ｂ；Ｃ時における縦孔２１内をそれぞれ撮像することによって互いに交差する横孔２８と縦孔２１との境界縁２９及びその近傍領域の撮像画像を取得する。ここでは、先頭側照明具８と後続照明具９が、縦孔入口３４から縦孔２１内を見た場合に見えないように位置決めされているので、縦孔入口３４から縦孔２１内を撮像した場合、先頭側照明具８や後続照明具９で縦孔２１の底が覆われることなく、先頭側照明具８及び後続照明具９の映っていない縦孔２１の底全体の画像を撮像できるので、互いに交差する横孔２８と縦孔２１との境界縁２９及びその近傍領域全体を撮像でき、互いに交差する横孔２８と縦孔２１との境界縁２９に生じているすべてのバリの検出が容易となる。尚、縦孔入口３４から撮像する場合、図２に示すように、支持体３が邪魔になって支持体３の下に位置する境界縁２９及びその近傍領域を撮像できないので、図２に示す状態で各状態Ａ；Ｂ；Ｃ時を撮像するとともに、照明装置１を棒体の中心を回転中心として例えば９０°回転させた状態においても各状態Ａ；Ｂ；Ｃ時の縦孔２１内を撮像することにより、図２の状態において支持体３の下に位置していた境界縁２９及びその近傍領域全体を撮像できる。つまり、合計６パターンの撮像画像を検査用画像としてコンピュータ３５に取り込んで図外の画像表示装置の画面に表示させる。検査員は画面に表示された検査用画像を見てバリの有無を検査する。   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.

最良の形態によれば、成形品２０の外面としての上面２３から内部に向けて形成された縦孔２１と成形品２０の外面としての側面２５；２７から内部に向けて形成された横孔２８とが互いに交差して貫通し合うように形成された孔構成を備えた成形品２０において、先頭側照明具８と後続照明具９とにより互いに交差する縦孔２１と横孔２８との境界縁２９及びその近傍領域の全体を先頭側照明具８と後続照明具９とで確実かつ明瞭に照明できるので、互いに交差する縦孔２１と横孔２８との境界縁２９及びその近傍領域の全体を撮像する回数を少なくでき、少ない撮像画像により境界縁２９に残っているバリ３０の有無を容易に検出できるようになる。つまり、バリの発生している可能性がある部分の撮像画像を容易に得ることができる。
また、上述した状態Ａの画像と状態Ｂの画像との差の絶対値を示す画像や、状態Ｃの画像と状態Ｂの画像との差の絶対値を示す画像をコンピュータ３５に作成させることによって、バリ３０を浮かび上がらせるような画像を得ることができ、バリ３０の有無を容易に検出できるようになる。 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.

他の形態１
照明装置１を用いたバリ検出用の画像の作成方法の他の形態１について説明する。図３に示すように、縦孔２１がワーク２２の上面２３からワーク２２の内部に向けて図外のドリルで形成された後に、一方の横孔２４がワーク２２の一方の側面２５から縦孔２１に到達するようにドリルで形成され、他方の横孔２６がワーク２２の他方の側面２７から縦孔２１に到達するようにドリルで形成されることによって、一方の側面２５と他方の側面２７とに跨って貫通する横孔２８と上面２３から横孔２８に到達する縦孔２１とが形成された成形品２０においても、縦孔２１と横孔２８との境界縁２９及びその近傍領域にバリ３０が発生する場合がある。 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.

この場合、照明装置１を先頭側照明具８側より一方の側面２５の横孔入口２４ａから挿入し、照明装置１の先頭側照明具８が縦孔入口３４の真下で境界縁２９の後方に位置するように照明装置１を位置決めし、電源供給選択スイッチ１７を操作して、先頭側照明具８のみを点灯させた状態Ａとして、エリアカメラ３３を用いて縦孔入口３４から縦孔２１内を撮像することによって横孔２８と縦孔２１との境界縁２９及びその近傍領域の撮像画像を取得する。この場合、先頭側照明具８の覆部６の表面には光拡散部７が形成されているので、先頭側照明具８の下方（裏側）に位置する横孔２８の内面は撮像されない。即ち、先頭側照明具８の上方及び横に位置する横孔２８と縦孔２１との境界縁２９及びその近傍領域の全体が、先頭側照明具８による拡散照明によって一度に確実かつ明瞭に照明された状態で撮像される。   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.

他の形態１によれば、成形品２０の外面としての側面２５と側面２７とに跨って貫通する横孔２８と成形品２０の外面としての上面２３から横孔２８に到達する縦孔２１とからなる孔構成を備えた成形品２０において、先頭側照明具８の上方及び横に位置する横孔２８と縦孔２１との境界縁２９及びその近傍領域の全体を、先頭側照明具８で一度に確実かつ明瞭に照明でき、かつ、エリアカメラ３３で一度に撮像できるので、１回の照明操作、１枚の撮像画像により、境界縁２９に残っているバリ３０の有無を容易に検出できるようになる。つまり、バリの発生している可能性がある部分の撮像画像を容易に得ることができる。
また、先頭側照明具８の覆部６が光拡散部７を備えない場合、横孔２８と縦孔２１との境界縁２９及びその近傍領域に光を照射している部分を先頭側照明具８による照射側とは反対側、即ち、縦孔入口３４からエリアカメラ３３で撮像した場合は、先頭側照明具８の裏側である下方に位置する横孔２８の内壁が撮像画像の背景部分として映ってしまうので、この撮像画像の背景部分がバリの検出検査の邪魔になる。
しかしながら、本発明の照明装置１の先頭側照明具８は、覆部６の表面に光拡散部７を備えるため、撮像画像におけるバリの背景部分が光拡散部７による乳白色の画像となるので、バリを容易に検出できる撮像画像を得ることができる。 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.

他の形態２
照明装置１を用いたバリ検出用の画像の作成方法の他の形態２について説明する。図４に示すように、縦孔２１がワーク２２の上面２３からワーク２２の内部に向けて図外のドリルで形成された後に、一方の横孔２４がワーク２２の一方の側面２５から縦孔２１に到達するようにドリルで横孔２８が形成されることによって、一方の側面２５から縦孔２１に到達する上面２３から横孔２８の位置より下方まで延長する縦孔２１とが形成された成形品２０においても、縦孔２１と横孔２８との境界縁２９にバリ３０が発生する場合がある。 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.

この場合、照明装置１を先頭側照明具８側より一方の側面２５の横孔入口２４ａから挿入して、先頭側照明具８の先端部分を横孔２８と縦孔２１との境界付近に位置させる。そして、電源供給選択スイッチ１７を操作して、先頭側照明具８のみを点灯させた状態Ａとして、エリアカメラ３３を用いて縦孔入口３４から縦孔２１内を撮像することによって横孔２８と縦孔２１との境界縁２９の部分の撮像画像を取得する。この場合、先頭側照明具８の照明光が先頭側照明具８と対向する縦孔２１の内壁面３６で反射した反射光が横孔２８と縦孔２１との境界縁２９及びその近傍領域の全体を照明する。   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.

他の形態２によれば、成形品２０の外面としての上面２３から内部に向けて形成された縦孔２１と成形品２０の外面としての一方の側面２５から内部に向けて形成されて縦孔２１に到達する横孔２８とからなる孔構成を備えた成形品２０において、横孔２８と縦孔２１との境界縁２９及びその近傍領域の全体を、先頭側照明具８で一度に確実かつ明瞭に照明でき、かつ、エリアカメラ３３で一度に撮像できるので、１回の照明操作、１枚の撮像画像により、境界縁２９に残っているバリ３０の有無を容易に検出できるようになる。つまり、バリ３０の発生している可能性がある部分の撮像画像を容易に得ることができる。   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.

他の形態１で使用する照明装置１は、先頭側照明具８の横孔入口２４ａから撮像される部分のみの覆部６の表面に光拡散部７が形成された構成であればよい。このように構成しても、先頭側照明具８の下方に位置する横孔２８の内面は撮像されないので、このような先頭側照明具８を用いた場合でも、先頭側照明具８の上方及び横に位置する横孔２８と縦孔２１との境界縁２９及びその近傍領域の全体を、一度に確実かつ明瞭に照明でき、一度に撮像できるので、１回の照明操作、１枚の撮像画像により、境界縁２９に残っているバリ３０の有無を容易に検出できるようになる。つまり、バリの発生している可能性がある部分の撮像画像を容易に得ることができる。   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.

他の形態２の方法の場合、反射光が横孔２８と縦孔２１との境界縁２９及びその近傍領域の全体を照明するので、先頭側照明具８としては覆部６の表面に光拡散部７を備えない先頭側照明具８を用いてよい。   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.

他の形態１や２で使用する照明装置としては、棒体の先端側に１つの照明具２を備えた構成であればよく、支持体３と後続照明具９を備えない照明装置でもよい。すなわち、照明具を孔内に挿入するために照明具を先端に有した棒体を備えた構成の照明装置を用いても他の形態１や２の方法を実現できる。   The illumination device used in the other forms 1 and 2 may have a configuration in which one illumination tool 2 is provided on the distal end side of the rod, and may be an illumination device that does not include the support 3 and the subsequent illumination tool 9. That is, the methods of the other modes 1 and 2 can be realized even by using an illuminating device having a rod body having an illuminating device at the tip for inserting the illuminating device into the hole.
