Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat plate-shaped part or a block-shaped part (hereinafter, unless particularly distinguished,
"Plate-shaped parts"), external shape inspection, color inspection, character inspection, different size and shape, different plating, presence or absence of characters, etc. The present invention relates to an inspection device for a flat plate-shaped component that automatically eliminates defective flat plate-shaped components and an inspection method using the inspection device.

[0002]

2. Description of the Related Art In the prior art, when inspecting different types of flat plate shaped parts, for example, FIG. 12 (FIG. 13 shows RR of FIG. 12).
As shown in the cross-sectional view and FIG. 14 (showing the view from the arrow Q in FIG. 13), the flat plate-shaped component 3 is conveyed on the inclined track 122 by the parts feeder 121 and is provided on the inclined track 122. The dimension line sensor 123 was used to inspect the outer diameter of the flat plate-shaped component, and the rotary actuator 124 was used to classify and discharge the good products into the good product discharge box 125 and the defective products into the defective product discharge box 126. Further, as shown in FIG. 15, a separating portion including a mountain-shaped separating gate 127 is provided in the middle of the inclined track 122 before the one-dimensional line sensor 123 to separate the flat plate-shaped component 3 and the flat plate-shaped component 3. Are supplied to the one-dimensional line sensor 123 so that they are not adjacent to each other.

[0003]

However, the conventional apparatus and method for inspecting a flat plate-shaped component have the following problems. 1) Since the one-dimensional line sensor 123 is used, when inspecting the outer shape and the like, it is necessary to provide a separating part when supplying the flat plate-shaped component to the inspection part, so that the dissimilar flat plate-shaped component is not clogged. It was difficult to determine the shape of the separation gate for separation, and the plate-shaped parts were clogged at the separation part, often stopping the inspection device.

2) Since the one-dimensional line sensor 123 is used, when inspecting the outer shape and the like, the conveyance speed varies when vibration occurs during conveyance or when slippage occurs due to the relation of flat plate-shaped parts, and the primary There is a possibility of making an erroneous determination because the speed at which the flat plate-shaped component passes on the original line sensor 123 changes.

3) Since the one-dimensional line sensor 123 is used, when inspecting the shape and the like, the shape inspection cannot be performed unless the flat plate-shaped component passes through the one-dimensional line sensor 123 in a fixed posture. 4) Since the one-dimensional line sensor 123 is used, it is not possible to inspect the color, characters, etc. on the surface of the flat plate-shaped component.

5) It was not possible to inspect the shape, color, characters, etc. of the flat plate-shaped component in the thickness direction. 6) When the discharge of good products and defective products is classified by the classification discharge mechanism provided at the end of the inclined track, the discharge direction of good products and defective products is the same as the transport direction. Due to the change in the falling direction, defective products may be mixed with good products. It had a drawback.

[0007]

In order to solve the above-mentioned problems, the present invention relates to a method of supplying a flat plate-shaped component to an inspection unit of a flat plate-shaped component, aligning them on a parts feeder, and feeding and conveying them to the inspection unit. At this time, the flat plate-shaped component is supplied by the inclined track, and in the inspection section, the material of the inclined track part is made substantially transparent, and the flat plate-shaped component is supplied to the image pickup device by the CCD.
A camera is used to provide an illuminating device at a position facing the CCD camera with the inclined track portion of the substantially light-transmitting body interposed therebetween, and the illuminating device irradiates and is supplied by a sloped track generated by light passing through the substantially light-transmitting body. CCD image of flat plate
An image processing device for capturing and analyzing with a camera was provided.

Further, the CCD camera and the illumination incident from the CCD camera side are provided, and the surface of the flat plate-shaped component is imaged by the incident illumination using the CCD camera to analyze colors, characters and the like. Further, using the above-mentioned supply method, a CCD camera is provided in the inspection portion in the thickness direction of the flat plate-shaped component, and C
Provided with the illumination from the side of the CD camera and CCD camera,
The configuration is such that the external shape and the surface of the flat plate-shaped component are imaged by epi-illumination using a CCD camera, and the shape, dimensions, colors, characters, etc. of the flat plate-shaped component in the thickness direction are analyzed.

Further, the non-defective product discharge portion is provided with an air nozzle directed from the lower direction of the inclined track to a direction substantially perpendicular to the conveyance direction of the inspection parts. Further, the air blown out from the air nozzle is provided with an electromagnetic valve controlled by the judgment of the image processing apparatus and connected to the air nozzle by an air tube.

[0010]

With the above-described structure, the method of supplying the flat plate-shaped parts to the inspection part is adjusted by replacing the device even if the shape and size are changed when the parts are aligned on the parts feeder and are conveyed to the inspection part. In addition, since the apparatus of the present invention does not restrain the outer shape of the flat plate-shaped component, there is no clogging during transportation, and it is possible to stably supply the flat plate-shaped component to the inspecting unit even if it is a heterogeneous flat-shaped component. In addition, the device can be simplified and unmanned operation can be performed for a long time. In addition, the inspection unit does not require separation even when adjacent flat plate-shaped components are in contact with each other, and can recognize and determine the overall outer shape and dimensions of the flat plate-shaped component. Also, in the non-defective product discharging part, the non-defective flat plate-shaped parts that are supplied to the inspection part by the above-mentioned supply method and judged as non-defective by the above-mentioned inspection method are blown off by air from the inclined track to the outside in the direction at a right angle, so that the solenoid valve fails. Even if the air is insufficient or shut off due to such reasons, defective products can be sorted and discharged without being mixed with good products.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an entire washer inspection device using an inclined track transport system for supplying an internal toothed washer (hereinafter, referred to as “washer” when there is no particular need to distinguish it) as shown in FIG. 7 in the present invention. Is. Figure 2
3 is a sectional view taken along line JJ of FIG. 1, and FIG. 3 is an enlarged view of the inspection unit A of FIG. The washer 2 introduced into the parts feeder 11 is supplied and conveyed by a method of conveying the washer 2 to an inclined track 12 which aligns the washer 2 in a tilted posture in the parts feeder 11. An inspection unit A is provided in the middle of the transportation, the CCD camera 13 captures an image of the outer shape of the washer 2 viewed in a plane, the image is analyzed and recognized in the image processing device 14, and the washer 2 is planarized. Determine the external shape and dimensions you saw.

Further, the CCD is also provided in the thickness direction of the washer 2.
The camera 21 is arranged, and shape differences such as thickness and unevenness are simultaneously inspected, and the defective washer and the different type washer are automatically discharged according to the result. FIG. 4 shows E of FIG.
The washer 2 inserted into the parts feeder 11 has a sectional shape of the inclined track 12 in the -E sectional view and is conveyed by the inclined track 12. In addition, the inspection unit A has a CCD
By using the camera, the size of the cross section of the inclined track 12 can be made constant without the need for a separation gate for separating and conveying the washer 2 and a posture changing gate for conveying the washer 2 in a constant posture. Therefore, the washer 2 can be transported without clogging.

In this apparatus, as described above, different types of washers having different outer diameters, inner diameters, and teeth are conveyed in the inclined posture by the conveyance by the inclined track 12 in the parts feeder 11 so that various kinds of washers can be obtained. A washer feeding device characterized in that it can be used as a feeding device, can be inspected without requiring a posture conversion gate and a separation gate for keeping the washer 2 in a constant posture, and has eliminated clogging.

The following measures are taken in order to convey the washer 2 on the inclined track and to inspect during the conveyance. First, in the inclined track conveyance, the washer 2 is conveyed at an inclination of 50 degrees, an inspection is performed during the conveyance, and the washer 2 is conveyed to the defective product discharge port 15 in the same posture after the inspection. In the inspection section A,
2 washers with 2 CCD cameras, CCD
The direction of the camera 13 is arranged in the plane direction of the washer 2, and the surface-emitting illumination 16 makes the washer 2 in the middle and CC
The inspection unit A is also arranged so as to face the D camera 13, and the inspection section A is also used for the inclined track conveyance, and the inclined track 12 of the inspection point is used.

By arranging the D camera 21 and the ring illumination 23 as epi-illumination and arranging them in the thickness direction of the washer 2, the thickness and unevenness can be inspected. In addition, as another embodiment, the inspection unit is shown in FIG.
As described above, by configuring the CCD color camera 51 and the ring illumination 52 that illuminates from the CCD color camera 51 side, color discrimination of the surface of the washer 2 or
Character recognition is possible, and it can be used for various purposes.

Secondly, regarding the discharging method, as shown in FIG. 6 (a detailed view of the KK section in FIG. 1), the washer judged by the image processing device 14 in the inspection section A is a non-defective air nozzle. It is blown off at 17 and discharged to a non-defective product discharge pocket 18 and then discharged to a non-defective product discharge box 19 (see FIG. 1). When the image processing apparatus 14 determines that the washer is a defective washer or a different washer, the air of the air nozzle 17 is stopped, the inclined track 12 conveys the defective washer to the defective product outlet 15, and the defective product discharge box 20 (see FIG. 1).
Is discharged to. In this case, before the image processing device 14 captures an image in the inspection unit A, determines that the washer is a defective washer and a different washer, and stops the air of the air nozzle 17,
Since there is a time difference, there is a non-defective washer and a defective washer on the inclined track 12 between the inspection unit A and the air nozzle 17, or different types of washers are mixed and in transit, so the time when the air nozzle 17 is stopped is defective. Set a sufficient time for the washer or the different type washer to pass through the air nozzle 17, and set the good washer together with the defective washer or the different type washer to the defective washer or about 1 or 2 before and after the different type washer.
By setting the time to stop the air of the air nozzle 17 so that it is transported to 5, it is not necessary to limit the defective washer or a single type of different washer, and it is not necessary to strictly control the timing of the air nozzle 17 It eliminates the risk of defective washers or foreign washers getting mixed in with good products.

Further, by blowing off the non-defective washer with air and discharging it out of the inclined track 12 in a direction approximately at right angles to the conveying direction, even if the air is insufficient or shut off due to a malfunction of the solenoid valve or the like, a defective washer or a different type is used. The washer is not discharged to the non-defective product discharge pocket 18 to eliminate the risk that a defective washer or a different washer is mixed.

Next, with respect to the inspection method in the image processing apparatus 14, the following measures were taken. 1) The CCD camera was used as a camera with a shutter so that a still image could be captured even during vibration or conveyance.

2) A timing signal to be picked up by a CCD camera is given to the inside of the image processing device 14, and an internal trigger signal is used to capture a single image, analyze and recognize it, and then immediately send a trigger signal to capture the next image. The image is output to a CCD camera, and images are continuously captured, processed, and inspected (called an internal trigger system).

3) All the washers conveyed on the inclined track can be discriminated even if they are not in a fixed posture. 4) The inspection was made possible even if the images of several washers were captured in the images captured by the CCD camera.

[0046]

As described above, according to the present invention, the method for supplying the slanted track is adopted, the image pickup device and the image processing device are incorporated, and the non-defective product is blown off by the air. It has the effects described below.

Inspection can be performed without being affected by the color and surface shape of the flat plate-shaped component. It is possible to inspect flat plate-shaped parts without being affected by speed changes due to vibration and slippage during conveyance of flat plate-shaped parts as in the past. By arranging a plurality of CCD cameras, it is possible to discriminate the planar shape, size, color, character, and shape, size, color character in the thickness direction of the flat plate-shaped component.

Since all the shape recognition and discrimination inspections are performed only by the image pickup device and the image processing device, it is not necessary to separately supply the flat plate-shaped components to the inspection unit, and in the middle of the inclined track. Since the separation function is unnecessary, the cause of clogging of flat plate-shaped parts can be eliminated and continuous inspection can be performed for a long time.

Since the classification after the determination of the flat plate-shaped parts is performed by air and the good products are blown off from the transport truck, it is possible to prevent defective products from being mixed with the good products.
