Clamping jaw and clamping device of robot special-shaped insert machine

Abstract

The invention discloses a clamping jaw and a clamping device of a robot special-shaped insert machine. The clamping jaw comprises a cylinder body, a piston rod, a pair of paws, a reset piece and a cap, wherein the piston rod and the reset piece are positioned inside the cylinder body, the reset piece is sleeved at the lower end of the piston rod, and the upper end of the reset piece presses against the lower end face of a flange part arranged at the upper end of the piston rod; the cap is fixed at the bottom of the cylinder body, the lower end of the reset piece presses against the upper end of the cap, and the lower end of the piston rod penetrates through the cap and extends out of the cylinder body; the paws are rotationally connected with the lower end of the piston rod by a center shaft pin and rotationally connected with the cylinder body by a rotating shaft pin. The piston rod is driven by compressed air to move up and down in the cylinder body to drive the paws to open and close to clamp electronic components, so that the structure is compact and the occupied space is small; and a single air pipe is not needed, so that the clamping and inserting response speed is improved and the service life is prolonged.

Description

Technical field [0001] The invention belongs to the field of plug-in machines, and particularly relates to a clamping jaw and a robot special-shaped plug-in machine clamping device. Background technique [0002] The robot shaped plug-in machine is a machine equipment that inserts electronic components into a designated position on the PCB circuit board. The robot shaped plug-in machine usually includes: machine shell, equipment base, PCB board transfer positioning device and robot. A clamping device is installed on the Z axis of the robot. The robot clamping device is usually equipped with multiple clamping jaws or suction cups for clamping and inserting electronic components; the PCB board transfer positioning device transfers the PCB board to a predetermined position, and the robot clamps The device inserts the corresponding electronic components into the designated position on the PCB board according to the instructions. At present, the clamping jaws generally use air cylinde...

AI Technical Summary

Problems solved by technology

At present, the gripper generally uses cylinders to control its gripping of electronic components and plug-in operations; each cylinder needs to be inserted with a gas pipe, which makes the robot gripping device more cumbersome, the routing of the gas pipe and signal lines is complicated, and the load is heavy; and because the cylinder is limited The service life of the clamping device and the limitations of the installation between the objects on the clamping device. After a period of use, the clamping jaws will become loose and damaged, which will affect the accuracy of the insertion of the equipment.
