AI Technical Summary
Existing screw-driven robotic grippers lack an axial motion structure for opening and closing, resulting in unstable gripping and large space occupation.
A servo motor drives the lead screw to rotate. Through the cooperation of the slide and the guide column, the moving clamping finger moves up and down along the guide column. Combined with the L-shaped curved plate and the protrusions and ribs on the fixed plate, the clamping is clamped in a staggered manner, realizing the up and down opening and closing movement, which enhances the clamping stability and reduces the space occupation.
It achieves more stable object clamping, reduces space occupation, simplifies cleaning and maintenance, and has a simple structure.
