AI Technical Summary
Existing gripping devices struggle to ensure the synchronization and coordination of the grippers when multiple objects are working together, failing to simultaneously meet the requirements of high-speed, long-stroke movement and high-precision positioning and gripping. Furthermore, they cannot maintain clamping force in the event of a power outage, leading to workpieces falling off.
The machine employs a frame-mounted barrel gripping unit and a connector gripping unit. It utilizes a first drive assembly driven by a servo motor and a second drive assembly driven by a cylinder, combined with the meshing transmission of a synchronous pulley and a synchronous belt and the support of a deep groove ball bearing, to achieve synchronous sliding of multiple barrel grippers and rapid opening and closing of connector grippers. It is equipped with a position detection unit consisting of a positioning pin, a sensing plate, and a slotted photoelectric sensor to ensure the accuracy and stability of the gripping process.
It enables simultaneous clamping of various types of workpieces, improves the synchronization accuracy and stability of the clamping device, ensures the reliability of the clamping force in the event of a power outage, reduces the risk of workpiece falling, and improves the efficiency and safety of automated production lines.
