Aiming at the promblem of the low position precision、not smoothly grasping and the shell of LED often be damaged even if it has been grasped by the big-power LED sorting machine

the Kinematics design is carried out for the key mechanism of the Positioning & Testing Instrument

the design idea of the combind cam mechanism is proposed. Final

the motion law of the cam followers is determined by the cam mechanism kinematic equation which is built and calculation based on the matlab

a good usage result the new combind cam mechanism is achieved.
