Abstract: A positioning device includes a base and two positioning mechanisms oppositely positioned on the base to position a workpiece. Each positioning mechanism includes a driver positioned on the base, a mounting member mounted on the base, a gear rack, a gear, and a positioning member. The mounting member defines a sliding groove. The gear rack slidably is received in the sliding groove and connected with the driver. The gear is rotatably connected with the mounting member and is meshed with the gear rack. The positioning member is fixedly-connected with the gear. The driver drives the gear rack to slide along the sliding groove to make the positioning member rotate and outstretch into an interior of the workpiece. The drivers drive two positioning members apply two opposite forces on the workpiece to positioning the workpiece.

Abstract: A transport configured to cooperate with a mechanical arm to pick up and place rubber plugs, includes a housing, a piston assembly received in the housing and a pickup assembly. The pickup assembly includes a guide base and a pickup member. The guide base defines a second receiving cavity. The housing also defines a first receiving cavity coupling with the second receiving cavity. A first tracheal joint and a second tracheal joint are provided on the housing. The piston assembly is slidably received in the first receiving cavity and driven by the first tracheal joint. The piston assembly defines a channel coupling with the second tracheal joint. The pickup member includes a connecting portion and an ejection portion inserting through the connecting portion. The connecting portion is received in the second receiving cavity. The ejection portion defines an air vent.
