AI Technical Summary
Traditional ultra-small needle roller feeding devices have large slide volumes, which makes the needle rollers easy to stack, lacks synchronous sorting, reduces feeding speed, affects assembly efficiency, and increases production costs.
Design an ultra-miniature needle roller feeding device, which adopts a directional sorting mechanism. Through the combination of guide groove, spiral channel, screening groove and screening hole, the device uses piezoelectric ceramic actuator to achieve directional sorting and synchronous feeding of needle rollers, prevents needle roller stacking, uses anti-reverse rod and recycling slide to screen needle roller size, and combines buffer components to reduce collision.
It achieves orderly arrangement and synchronous sorting of needle rollers, improves feeding speed and quality, reduces needle roller breakage, increases production efficiency and reduces costs.
