置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a positioning illumination image pickup device, particularly a flat IC.
The present invention relates to a positioning illumination image pickup device for detecting the position of a lead.
従来の位置決め用照明撮像装置について図面を参照して
詳細に説明する。A conventional positioning illumination imaging device will be described in detail with reference to the drawings.
第２図は従来の位置決め用照明撮像装置の一例を示す模
式図である。FIG. 2 is a schematic diagram showing an example of a conventional positioning illumination image pickup device.
第２図に示す位置決め用照明撮像装置は (A)環状の蛍光灯９、 (B)蛍光灯９の中心に設置されたカメラ１３、 (C)カメラ１３に接写リング２２を介して取付けられた
短焦点のレンズ２１、 (D)レンズ２１に挿入され、蛍光灯９の光を散乱するに
足る直径を有する散乱板、 とを含んで構成される。The positioning illumination imaging device shown in FIG. 2 is attached to (A) a circular fluorescent lamp 9, (B) a camera 13 installed at the center of the fluorescent lamp 9, and (C) a camera 13 via a close-up ring 22. A short-focus lens 21, and a (D) scattering plate which is inserted into the lens 21 and has a diameter sufficient to scatter the light of the fluorescent lamp 9.
ＩＣ１は吸着器２によって吸着され、遮光板５により背
後の光を遮断されている。The IC 1 is adsorbed by the adsorber 2 and the light behind it is blocked by the light shielding plate 5.
上述した従来の位置決め用照明撮像装置は、ＩＣのリー
ド全部を均一に照明できず、リードにレンズが映るため
コントラストが低下するという欠点があった。The conventional positioning illumination image pickup device described above has a drawback in that it is not possible to uniformly illuminate all of the leads of the IC, and the lens is reflected on the leads, so that the contrast is lowered.
本考案の位置決め用照明撮像装置は、 (A)環状の蛍光灯、 (B)前記蛍光灯の中心に設置され、前記蛍光灯の光を散
乱させて内部に放出し、一端にレンズ取付け用の第１の
開口部を有し、対向する他端に被位置決め部品が挿入さ
れる第２の開口部を有する散乱殻体、 (C)前記第１の開口部に設置される小口径で長焦点のレ
ンズ、 (D)前記レンズに取付けられたカメラ、 とを含んで構成される。The positioning illumination image pickup device of the present invention is (A) an annular fluorescent lamp, (B) is installed at the center of the fluorescent lamp, scatters the light of the fluorescent lamp and emits the light to the inside, and one end for mounting a lens. A scattering shell having a first opening and a second opening into which the positioned component is inserted at the other end opposite to the scattering shell, (C) a small aperture and long focus installed in the first opening Lens, and (D) a camera attached to the lens.
次に、本考案の実施例について図面を参照して説明す
る。Next, an embodiment of the present invention will be described with reference to the drawings.
第１図は本考案の一実施例を示す模式図である。FIG. 1 is a schematic view showing an embodiment of the present invention.
第１図に示す位置決め用照明撮像装置は、 (A)環状の蛍光灯９、 (B)蛍光灯９の中心に設置され、蛍光灯９の光を散乱さ
せて内部に放出し、一端にレンズ取付け用の第１の開口
部を有し、対向する他端に被位置決め部品が挿入される
第２の開口部を有する散乱コーン１７、 (C)前記第１の開口部に設置される小口径で長焦点のレ
ンズ１２、 (D)レンズ１２に取付けられたカメラ１３、 とを含んで構成される。The positioning illumination imaging device shown in FIG. 1 is installed in the center of (A) an annular fluorescent lamp 9 and (B) a fluorescent lamp 9, scatters the light of the fluorescent lamp 9 and emits the light to the inside, and a lens at one end. A scattering cone 17 having a first opening for mounting and a second opening into which the positioned component is inserted at the opposite other end, (C) A small diameter installed in the first opening And a camera 13 attached to the lens 12 (D).
蛍光灯９は２０Ｗ、レンズ１２はＣマウントでＦ＝４，
ｆ＝７０ｍｍ、散乱コーン１７の全長（１＋２）は
１４０ｍｍ，第１の開口部の直径は４５ｍ，第２の開口
部の直径３は１８０ｍｍ（ＩＣ１の大きさは２５×２
５ｍｍの場合）に選んだ時良好なコントラストが得られ
た。Fluorescent lamp 9 is 20W, lens 12 is C mount F = 4
f = 70 mm, the total length (1 + 2) of the scattering cone 17 is 140 mm, the diameter of the first opening is 45 m, and the diameter 3 of the second opening is 180 mm (IC1 size is 25 × 2).
Good contrast was obtained when it was selected (for 5 mm).
なお、散乱コーン１７の代りに、球形の散乱体を用い、
蛍光灯９を複数使用することも考がえられる。In addition, instead of the scattering cone 17, a spherical scatterer is used,
It is also conceivable to use a plurality of fluorescent lamps 9.
本考案の位置決め用照明撮像装置は、ＩＣのリード全部
を均一に照明でき、リードにレンズが映らないのコント
ラストが向上できるという効果がある。The positioning illumination image pickup device of the present invention has an effect that it can uniformly illuminate all the leads of the IC and can improve the contrast in which no lens is reflected on the leads.
