COMPONENT FEEDER EXCHANGE CART, AND MECHANISM AND METHOD FOR POSITIONING COMPONENT FEEDER

摘要

The purpose of the present invention is to provide a cart for changing component supply unit used for a component mounting apparatus, capable of easy and safe changing and achieving positioning with high accuracy by having a compact lifting mechanism. The cart comprises a base frame 40, driver 55 for expanding the operation stroke of a hydraulic jack and transferring the movement into an up and down motion, a pair of elevating rods 53 simultaneously lifted of lowered by the movement of the driver 55, a pair of supporting frame 51 for operably support the elevating rods 53 by means of guide rollers 52, and a holder 80 fixed to the elevating rods 53 for lifting and lowering the component supply unit, wherein a multi purpose space is formed surrounded by the driver 55, a pair of the elevating rod 53, and the holder 80. By using a positioning means containing a structure where a positioning pin 29 of the fixing device 4 fits in a V shaped slot 35 formed to the component supply unit 2 side, the component supply unit 2 may be positioned in two different direction by pushing the component supply unit 2 to a single direction.
