Abstract:
A mounting apparatus for electronic parts comprising:a plurality of loading members for electronic parts, each having a loading through-hole extending in the up-and-down direction for loading plural electronic parts to be mounted on a printed circuit board, and a detachment preventative mechanism for prohibiting incidental descent of the electronic parts from the loading through-hole, the electronic parts being loaded in a stacked state in groups of the same sorts;a loading unit for loading electronic parts in said plurality of loading members by insertion into said through-hole and including a supporting unit for supporting a single electronic part that was last inserted into the loading through-hole of the loading member so that the last-inserted electronic part is positioned at an optimum loading position in the vicinity of an opening end of the loading through-hole;a loading member furnishing casing in which is arranged at least a set of loading members for electronic parts each accommodating at least a set of electronic parts to be loaded on the printed circuit board;a loading member holder having a plurality of holding portions each holding one of said set of the electronic parts arrayed and held in said loading member furnishing casing; andan electronic part loading device for mounting electronic parts on the printed circuit board and having said loading member holder mounted therein, said electronic part loading device including a plurality of extruder members arranged for being inserted via upper opening ends of said loading through-holes of said loading members for electronic parts held by said loading member holder and an extruder member descent control mechanism adapted for controlling the descent by the self-gravity of these extruder members and for annulling the controlled state to permit descent of the extruder members;said extruder members descending by their own weight through the insides of the loading through-holes when said extruder member descent control mechanism enables descent of said loading through-holes to eject the electronic parts from the loading members for electronic parts via lower end openings in order to put the electronic parts at pre-set positions on the printed circuit board arranged below said loading member, wherein:said loading member holder carries identification symbols in association with plural holding portions provided on the holder and wherein said loading members for electronic parts are each provided with identification symbols associated with the identification symbols provided in each holding portion,the identification symbols provided on said loading members for electronic parts are numerical figures or letters indicating the arraying sequence of the plural holding portions and wherein the identification symbols provided on the loading members for electronic parts are numerical figures or letters associated with the numerical figures or symbols indicating the numerical figures or symbols specifying the arraying sequence of the plural holding portions, andthe loading member furnishing casing has a series of identification symbols comprised of numerical figures or letters associated with the numerical figures or letters specifying the arraying sequence of the plural holding portions, said at least one set of the loading members for electronic parts being arrayed in said loading member furnishing casing with the identification symbols of the loading members for electronic parts in agreement with the numerical figures or letters provided on said loading member furnishing casing.
