Electronic component conveying device

[0016]Such asfigure 1 The illustrated method for inspecting electronic components based on machine vision includes the following steps: Step one: Collecting damaged image samples on the surface of the electronic components and undamaged image samples of the electronic components, and collecting ultrasound waves corresponding to the damaged image samples on the surface of the electronic components. Flaw detection signals and ultrasonic flaw detection signals corresponding to image samples without damage to electronic components;

[0017]Step 2: Manually mark the damage type of the damaged image on the surface of the electronic component, and obtain the marked damaged image sample on the surface of the electronic component;

[0018]Step 3. Use the partially labeled damaged image samples on the surface of the electronic components, the non-damaged image samples of the electronic components, and the corresponding ultrasonic flaw detection signals as the positive sample set and the negative sample set of the training set; label the rest of the electronic components Surface damage image samples and corresponding ultrasonic flaw detection signals are used as the test set; VGG16 convolutional neural network is used for training to obtain the final training model;

[0019]Step 4. Use an ultrasonic flaw detector and a camera to collect the surface image of the electronic component and input the ultrasonic flaw detection signal into the final training model to monitor the electronic component online.

[0020]A unique code is printed on the surface of the electronic component; the final training model records the picture of the electronic component corresponding to the unique code, and marks the damage of the picture of the electronic component.

[0021]The unique code is a barcode or a QR code. The mark is to paint the entire damage in red and indicate the type of damage.

[0022]In step four, the pictures of the front and back of the electronic components are collected. After the detection of the electronic component in step 4 is completed, the number is scanned by the code scanner, and when the corresponding electronic component is a damaged component, an alarm wirelessly connected to the code scanner will alarm.

[0023]In order to adapt to the above detection method, the present invention also provides a corresponding conveying device

[0024]Including the upper conveyor belt (1), the upper conveyor belt (1) is installed with the first visual inspection device (2) and the ultrasonic detector (3); the upper conveyor belt (1) has a number of through holes formed on the surface; the upper conveyor belt (1) is installed inside There is a suction box (4). The upper and lower surfaces of the suction box (4) are formed with strip grooves (5), and the strip grooves (5) are formed with a number of first suction holes (6); the upper conveyor belt ( 1) The passive conveying roller (9) on one side is hollow, the upper conveyor belt (1) is formed with an annular groove (7), and the annular groove (7) is formed with a number of second suction holes (8); the passive conveying roller (9) The first negative pressure tube (10) is connected to the shaft, and the second negative pressure tube (11) is connected to the adsorption box (4); the first negative pressure tube (10) and the second negative pressure tube (11) are both connected There is a negative pressure device (12), and the negative pressure device (12) is a negative pressure pump. A lower conveyor belt (13) is installed below the upper conveyor belt (1), a gap (17) is formed between the upper conveyor belt (1) and the lower conveyor belt (13), and the thickness ratio of the gap is 0.1-1 cm larger than the thickness of the electronic component. A second visual inspection device (14) is installed above the lower conveyor belt (13); a code scanner (15) is installed at the end of the lower conveyor belt (13), and the code scanner (15) is wirelessly connected with an alarm (16). In this way, the electronic components are placed on the upper conveyor belt (1), and are detected by the first visual inspection device (2) and the ultrasonic detector (3), and then transported after being sucked by the suction box (4) and the passive conveying roller (9) once Go to the bottom of the upper conveyor belt (1) and after passing through the suction box (4), the negative pressure is released, and the components are transported by the lower conveyor belt (13), and then pass through the second visual inspection device (14) to take pictures and inspect, and then pass through the code scanner (15) Scan the unique code. If the corresponding electronic component is a damaged component, the alarm will alarm and the worker or manipulator will pick out the damaged electronic component. The conveyor belt is a rubber conveyor belt.

[0025]The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection of the present invention. Within range.
