[0002] With the improvement of living standards, the demand for fresh flowers has increased significantly, leading to higher expectations for the efficiency and speed of flower sorting systems. Traditional manual sorting methods are time-consuming, labor-intensive, costly, and inefficient. After the implementation of automated sorting production lines, production capacity has increased by approximately 2.5 times, labor costs have decreased by nearly 80%, and product quality is more stable with more precise grading.

The servo motor 3 of the lifting module 31... 11. Start-up: Drive the helical gear 315 downward along the helical rack 314. Simultaneously, the motor mounting plate 316 moves downward along the guide rail 313, driving the entire camera detection module 32 downward to a suitable shooting position (this position is calculated and fed back to the servo motor 311 based on the height of the flowers stored in the MES). Cameras 3225 on the second vision detection component 323, the third vision detection component 324, the fourth vision detection component 325, and the fifth vision detection component 326 simultaneously take pictures and transmit the captured data to the MES. The barrel roller line 1 conveys the flower barrel 5 containing flowers to the manual re-inspection screen 4. After a set of photoelectric switches detects the flowers, the transmission stops. After manual re-inspection, the inspection results are uploaded to the manufacturing execution system and then to the MES.
