[0001] This utility model relates to the technical field of auxiliary tools for screw feeders, and in particular to a pneumatic screw feeder. Background Technology

[0002] The current field of automated assembly has increasingly stringent requirements for the efficiency and cost control of screw feeding equipment. Traditional screw feeders often rely on small robotic arms to grip materials, and their complex mechanical structure leads to high equipment costs. At the same time, the gripping process of the robotic arm is cumbersome, and the speed of material movement in multiple axes is limited, which cannot meet the needs of high-efficiency production. Especially in the Z-axis direction, when traditional robotic arms grip materials, due to the limitations of the mechanical transmission structure, multiple joint rotations and positioning calibrations are required, resulting in slow gripping actions. This greatly affects the overall efficiency of screw feeding and has become a key bottleneck restricting the speed-up of automated assembly lines. Therefore, it is necessary to improve and address the above problems. Utility Model Content
