Image Signal Acquisition Method for Intermittent Material Conveying Equipment

Abstract

The invention relates to an image signal acquisition method for intermittent material conveying equipment, comprising the steps of setting a CCD acquisition camera at a position above the discharge end of a conveying unit, and setting the CCD acquisition camera on a rotating mechanism so that when the conveying unit is conveying, The collection end of the CCD acquisition camera points to the position above the discharge end of the conveying unit. When the conveying unit stops conveying, the position above the discharge end of the CCD acquisition camera is kept away from the position above the discharge end of the conveying unit; the self-cleaning mechanism is set at the position above the discharge end of the CCD acquisition camera The position in front of the end, when the collection end of the CCD acquisition camera is far away from the position above the discharge end of the conveying unit, the self-cleaning mechanism cleans the acquisition end of the CCD acquisition camera, when the acquisition end of the CCD acquisition camera points to the position above the discharge end of the conveying unit When the self-cleaning mechanism cleans the collection end of the CCD collection camera, the method realizes the automatic cleaning of the CCD collection camera and ensures the reliability of the image signal collection of the CCD collection camera.

Description

Technical field [0001] The present invention relates to the technical field of intelligent equipment, in particular to an image signal acquisition method of an intermittent material conveying equipment. Background technique [0002] CCD collection cameras are widely used in industrial equipment to identify items. For example, in the field of color sorting machines, CCD collection cameras can accurately collect items to be selected. By judging the color or shape of the item, the item can be identified. For screening, one end of the CCD collection camera is set above or below the path of the product. When it is above the product, the color of the product on the upper conveyor belt is collected by the CCD collection camera, and then sent to the control unit for judgment. After judgment, Start the control mechanism to remove the different-color or special-shaped belt sorting materials from the conveying device. It is not only used in color sorters, but also in other industrial equipm...

[0002] CCD acquisition cameras are widely used in industrial equipment and can identify items. For example, in the field of color sorters, CCD acquisition cameras can accurately capture the items to be selected, and then realize the identification of items by judging the color or shape of the items. For screening, one end of the CCD acquisition camera is set above or below the path of the product. When it is above the product, the color of the product on the upper conveyor belt is collected by the CCD acquisition camera, and then sent to the control unit for judgment. After the judgment, Start the control mechanism to remove the different-color or special-shaped belt sorting materials from the conveying device. It is not only used in color sorters, but also in other industrial equipment. There are also cases of using CCD cameras to collect color or shape information of items; When judging the material conveyed intermittently, when the CCD acquisition camera collects material information, it is necessary to protect the CCD acquisition camera to prevent the CCD acquisition camera from continuously facing the material, so as to prevent the material from bouncing up and damaging the CCD when the material is conveyed intermittently. The acquisition camera, and when the existing materials are actually conveyed, huge dust will be generated, which will cause huge interference to the signal acquisition of the CCD acquisition camera. Soot cleaning mechanism, however, most of the cleaning mechanisms in the prior art are cylinder-driven cleaning brushes. Although the above method can play a role in cleaning dust, the cost is high, and a separate pressure air circuit system needs to be set up to clean the cylinder. It is obviously not suitable for some systems that are inconvenient to arrange pressure gas lines
