The tilting unit 20 of the main body equipment to which the present invention is coupled is mounted on an orthogonal robot as a configuration for a'top surface inspection' to move the inspection-only jig 10 to an X-axis robot and a Y-axis robot in any direction and at any angle. It is also tilted so that the curved portion of the upper surface of the insert 11 to be inspected, that is, each surface and corner of the concave portion and the convex portion can be inspected.

A control and command process for inspection of the controller of the main body equipment to which the present invention is coupled will be described with reference to FIGS. 7 and 8 as follows.

The inserts to be inspected according to the present invention are supplied to the inspection track at the'supply position', and a plurality (1 to 9) are loaded on a jig dedicated to inspection that professionally transports the product and transferred to the'inspection position'. The detection command is executed at the'inspection location'. That is, it detects product distortion (x, y, θ) with macro vision and micro vision in charge of inspection and performs two-dimensional correction. The next step is to calculate the inspection position of the product by performing three-dimensional correction by adjusting the two-dimensional correction value, the thickness value, and the depth of the product in the position angle calculation unit receiving the operation command, and transmits the position of the product to the control unit to the target position. Carry out a move to. When the control is completed in the control unit, a three-dimensional analysis of the detection target and an image of the detection position are acquired and secured. In the next step, the detection unit analyzes and inspects the image to determine good/defective products.

The operation sequence of the inspection-only jig of the high-speed inspection equipment for carbide inserts using the orthogonal robot according to the present invention is as follows.

1. The insert 11 to be inspected is loaded on a jig for inspection at the pallet transfer part of the main body equipment, and goes through the process of upper surface inspection → bottom surface inspection → side inspection → discharge along the inspection-dedicated jig transfer part of the'ㅁ' shaped shuttle track. .

2. According to the above-described process, the inspection-exclusive jig 10 arrives at the'top-surface inspection' position by the inspection-exclusive jig transfer unit for the'upper inspection' of the inspection target insert.

end. The inspection-only jig 10 enters the'inspection position' by the transfer belt of the jig transfer unit, is maintained in a horizontal state, is aligned, and the inspection preparation is completed.

I. A plurality of inspection target inserts 11 are sequentially inspected.

(At this time, the illumination shining from the backlight from the lower side projects the insert to be inspected through quartz, and the inspection vision (macro vision) on the upper side acquires an image)

All. The X-axis robot, the Y-axis robot, and the coupling plate of the tilting unit 20 are tilted in a required direction and at a required angle, and edge inspection (micro vision) is performed.

la. The edge portion of the insert to be inspected tilted by the tilting unit 20 is horizontal.

hemp. When the focal length of the horizontally tilted edge portion is different, the lens of the most appropriate depth among the plurality of lenses 112 of the apparatus for automatically adjusting the depth of the image inspection camera according to the present invention adjusts the depth from the lower side of the camera. 5 and 3)

(At this time, by tilting the direction and angle of the tilting unit, each surface and corner of the concave and convex parts are inspected without missing, and the'focal length difference measured by the image inspection camera according to the depth of each lens input to the controller. A lens capable of correcting'is selected, and finally, fine depth correction is performed by the camera.)

bar. When'inspection' is completed in two visions, the inspection-only jig 10 advances to the track of the inspection-only jig transfer unit and is transferred to the next step.

The MGT of the carbide insert high-speed inspection equipment using the orthogonal robot according to the present invention and the automatic depth control device of the top surface inspection camera of the carbide insert for milling have the following advantages.

First, the MGT of the high-speed inspection equipment for carbide inserts using the orthogonal robot according to the present invention and the automatic depth control device for the top surface inspection camera of the carbide insert for milling are the camera depth using a lens for inspection of the edge of the top surface of the insert 11 to be inspected. Specially manufactured automatic control device.

Therefore, it is possible to improve product productivity by increasing the inspection efficiency of the curved surface of the upper edge portion of the plurality of inspection target inserts of the inspection-only jig.

In addition, the automatic depth control device of the MGT and the top surface inspection camera of the carbide insert for milling of the high-speed inspection equipment using the orthogonal robot according to the present invention is configured to automatically correct the depth of the camera using lenses having various depths.

Therefore, it is possible to improve the efficiency of the equipment by resolving the delayed process problems of the main body equipment by remarkably shortening the time required for the camera to directly correct the focal length different from the tilting of the edge during the'top inspection'.

In addition, the depth correction lenses of the MGT of the high-speed inspection equipment for carbide inserts using the orthogonal robot according to the present invention and the automatic depth control device for the top surface inspection camera of the carbide insert for milling are manufactured using materials with different physical properties and combined by type to provide various depths of depth. Was configured.

Therefore, the lens applied to the present invention has a correction effect of about 3 times the depth of field (1.5mm) compared to the basic depth of field (0.5mm) of the camera (micro vision).
