The invention relates to a precision reciprocating transfer device which is composed of a
cam oscillating bar mechanism, a
cam lifting mechanism, a transmission mechanism, a suction
nozzle component, a
workbench and a shaft bracket component. A main shaft
clockwise rotates, an oscillating bar
cam in the oscillating bar mechanism is driven to rotate, an oscillating bar cam roller moves by being attached to a cam, an oscillating bar swings in a reciprocating and intermittent mode along an oscillating bar rotating shaft according to the trace curve of the oscillating bar cam, a cross-garnet butt cam roller on the oscillating bar drives a cross-garnet butt to swing in a reciprocating and intermittent mode, the main shaft
clockwise rotates, a lifting cam in the lifting mechanism is driven to rotate, a lifting cam roller moves by being attached to a lifting cam groove, the main shaft rotates, meanwhile, the oscillating bar cam and the lifting cam are driven to rotate, the cam oscillating bar mechanism and the cam lifting mechanism alternatively move, a translation bar is driven to complete the
reciprocating motion of vertically downward moving, vertically upward moving, horizontally left moving, vertically downward moving, vertically upward moving and horizontally right moving resetting in sequence, and the control difficulty of a
system is reduced. A transfer track depends on a mechanical structure, and the accuracy requirement for a driving motor is effectively lowered.
