The optimization design for the locus of the forwarding sucker in a single-sheet feeder is discussed Through theoretical analysis,a mathematical model of optimization design is set-up in which the object function is the minimum deviation between the real locus and the required locus for a given point on the connecting rod.

According the technological characteristic and process conditions for suction nozzle of paper-feeding mechanism,a kind of design method of conjugate cams was established for high speed paper feeding,by choosing or designing motion law of cam follower.

Design of blowing-suction typed suction mouth of grassland locust■suction trapping machine;

Aiming to the lower rate of suction trap and locust bumping against the suction mouth wall and smashing etc.

By the component size, end electrode and lead wire, surface flatness, tape and reel and so on bring in detail how to select components in order to enhance the pick the place quality, Detail how to choose and set up the nozzle and pressure of SMD placement machine to enhances the pick the place quality.
