[0002] During the production of crystal hot-fix rhinestones, defects such as surface scratches, bubbles, impurities, and dimensional deviations can occur due to factors such as processing techniques and raw materials. If these defective rhinestones enter the market, they will seriously affect product quality and brand image. Currently, most appearance inspection of crystal hot-fix rhinestones is done manually. Manual inspection is not only inefficient and labor-intensive, but the results are also easily influenced by the subjective factors of the inspectors, leading to low accuracy. Although some machine vision inspection is used, existing inspection equipment often has limited functions, cannot perform comprehensive appearance inspection of crystal hot-fix rhinestones, and cannot quickly and accurately sort out defective products. Therefore, we propose an appearance inspection device for crystal hot-fix rhinestones. Utility Model Content

[0022] In this embodiment, the crystal hot rhinestones are first placed in the placement box 2 on the conveyor belt 1, and then the conveyor belt 1 is started so that the conveyor belt 1 drives the crystal hot rhinestones to the position of the detection mechanism 3 through the placement box 2.

[0023] When the crystal rhinestone reaches the position of the inspection mechanism 3, the ring light source 32 and the strip light source 35 are turned on to provide illumination for the crystal rhinestone. At the same time, two industrial cameras 33 simultaneously acquire surface images of the crystal rhinestone from different angles, and the laser range sensor 34 detects the height of the crystal rhinestone. The image information acquired by the industrial cameras 33 and the size information detected by the laser range sensor 34 are transmitted to the controller 6 in real time. The controller 6 processes and analyzes this information to determine whether the crystal rhinestone has appearance defects and size deviations.

[0024] When the crystal rhinestone is conveyed to the end of the conveyor belt 1, the controller 6 controls the motor 42 to operate. The motor 42 drives the rotating arm 43 to rotate. At the same time, the cylinder 44 and the air pump 46 operate simultaneously. The operation of the cylinder 44 drives the height of the suction cup 45 to be adjusted. Thus, the air pump 46 and the suction cup 45 work together to pick up the crystal rhinestone. If the controller 6 determines that the crystal rhinestone is defective, it picks it up and puts it into a sorting box 5. If it is determined to be good, it drives the crystal rhinestone to fall into another sorting box 5 for storage.

[0025] Throughout the inspection process, by reasonably adjusting parameters such as the shooting angle of the industrial camera, the installation position of the laser rangefinder, and the light intensity of the light source components, the accuracy and efficiency of the inspection can be further improved.

[0026] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
