To remove a foreign substance which is generated when inserting an expansion blade part between segment coils.SOLUTION: A foreign substance removal system comprises: a processing station which molds a front end of a segment coil; and a foreign substance removal station including a blade table on which an expansion blade part transferred from the processing station by a transfer section is mounted, a table rotation section for rotating the blade table around an axis of the expansion blade part, an air blow section which is provided on a lateral of the blade table and blows air to a rear end of the expansion blade part on the blade table, an air blow suction section which is provided at a position opposite to the air blow section and sucks air from the air blow section, a rotary brush section which rotates a brush part while pressing the brush part to the front end of the expansion blade part on the blade table, and a brush suction section which is provided in the rotary brush section and sucks a foreign substance deposited to the brush part.SELECTED DRAWING: Figure 1

To provide a foreign matter detection method with which it is possible to detect foreign matter on the wiring of electronic components.SOLUTION: The foreign matter detection method comprises steps for: preparing an electronic component that includes a wiring board having a wiring; and detecting foreign matter on the surface of the wiring. The step for detecting the foreign matter includes: (1) irradiating the surface of the wiring with first light having an emission peak wavelength in the range of wavelengths of 350 nm to 495 nm inclusive, in the emission spectrum of which the emission intensity of light in wavelength of 500 nm or greater is 5% or less with respect to emission intensity in the emission peak wavelength, and imaging the surface of the wiring to acquire first image information; (2) irradiating the surface of the wiring with second light that includes light in wavelength of 500 nm or greater and imaging the surface of the wiring to acquire second image information; (3) performing difference processing on the first and second image information to acquire third image information; (4) determining a portion of the third image information that indicates lower brightness than the preset reference value of brightness as the foreign matter, thereby detecting the foreign matter.SELECTED DRAWING: Figure 1

This application discloses a method, apparatus, equipment, medium, and product for detecting foreign objects on mine conveyor belts, relating to the fields of computer vision and artificial intelligence. The method includes acquiring original images of the mine conveyor belt area; sequentially performing low-light image enhancement and super-resolution reconstruction processing on the original images to obtain high-quality, high-resolution images; identifying and locating foreign objects in the high-resolution images using an improved target detection model; and outputting detection results including foreign object category labels, confidence scores, and location coordinates. This application achieves high-precision, high-recall real-time detection and accurate location of various foreign objects such as gangue, anchor bolts, and ironware, significantly improving practicality and reliability, effectively reducing missed detections and false detections, and providing reliable technical support for safe coal mine production.
