[0040] Further, the driving motor 203 drives the sliding sleeve 202c of the feeding rod 202 to slide along the sliding column 202b, so that the limiting rod 204 and the fixing assembly 205 connected thereto move as a whole; the operating motor 204b controls the movement of the rod body 204a, drives the fixing assembly 205 to be accurately positioned through the connecting plate 204c; the operating cylinder 205c drives the extension rod 205b to move on the connecting frame 205a, so that the material taking suction nozzle 207 at the end of the fixing plate 206 completes the precise grabbing and placing action, and through the cooperation of the guide mechanism of the sliding rod 202a and the sliding column 202b and the driving system of the motor and the cylinder, the automation operation of feeding, positioning and assembling is realized, and the precise grabbing and stable assembly of the micro spring are ensured.

[0048] In summary, the real-time detection and automatic deviation correction of the circlip position are realized through the positioning CCD 308 and the visual light source 307 system, which significantly improves the assembly accuracy and consistency; the modular mechanical design combined with the cooperative control of the driving motor 203, the cylinder and the fine adjustment assembly 306 makes the feeding, material taking and positioning process fast and accurate, effectively avoiding the problems of material jamming and missing assembly; the cooperation of the vibration disc 303 and the pushing assembly 305 ensures stable feeding of the circlip, and the linkage design of the material taking suction nozzle 207 and the fixed assembly 205 improves the operation flexibility and efficiency; the overall structure is compact and highly automated, greatly reducing the need for manual intervention, suitable for quick changeover of different specifications of circlip, improving production efficiency while reducing maintenance cost, and ensuring the stability and reliability of the assembly process through the dual protection of mechanical positioning and optical detection.
