Abstract

The invention discloses a gear appearance defect detection and sorting system based on machine vision, belonging to the technical field of machine vision detection. The gear appearance defect detection and sorting system based on machine vision is characterized by comprising an ARM (advanced RISC machine) controller (1), an image capture module (2), a display module (3), a sound-light alarm module (4), a data transmission interface (5), a defect character database (6), a power module (7), a PLC (programmable logic controller) (8), a conveying unit (9), a defective gear positioning unit (10), a sorting execution unit (11), a light source irradiation module (12), a CCD (charge-coupled device) industrial camera (13) and a to-be-detected gear (14). Compared with the prior art, the gear appearance defect detection and sorting system has the advantages of simple structure, convenience in installation and debugging, high reliability, high measurement accuracy, low power consumption, easiness in popularization and promotion, convenience in maintenance, and the like.

Description

technical field [0001] The invention belongs to the technical field of machine vision detection, and more specifically, belongs to a machine vision-based detection and sorting system for gear appearance defects. Background technique [0002] Gears are widely used in mechanical transmission and the entire mechanical field. Gear detection technology is of great significance to the machinery industry. Gears are generally composed of teeth, tooth grooves, end faces, legal faces, addendum circles, dedendum circles, base circles, and indexing circles. According to its shape, it can be divided into cylindrical gear, bevel gear, non-circular gear, rack and worm gear, etc.; according to the shape of tooth line, it can be divided into spur gear, helical gear, herringbone gear and curved gear. Gear products may have defects such as tooth chipping, missing teeth, crooked teeth, and cloaks, so there are many testing items and the measurement process is complicated. The special gear de...
