Abstract

A supply chute 11 has a nut send-in port 14 at its upper end, and is composed of an inclined chute 12 inclined obliquely downward, and a curved chute 13 coupled to the lower end of the inclined chute 12 and curved like an arc obliquely downward. A nut support mechanism 40 is disposed at a nut send-out port 15 provided at a terminal end of the curved chute 13, for supporting the nuts 60 being forwarded so that their bonding side 62 may be in an oblique downward position nearly orthogonal to the axial line of a guide rod 20. The inclined chute 12, the curved chute 13, the guide rod 20, and driving means 25 for moving the guide rod 20 back and forth in an oblique downward direction are mounted on a stand 22 installed rotatably on a support member 33 by way of a horizontal support shaft 35, and the support member 33 is coupled and fixed to a main body arm 2 of the bonding machine 1. When the guide rod 20 moves forward obliquely downward, the holding pin 21 protruded on the front end of the guide rod 20 penetrates through screw holes 61 of the nuts 60 supported on the support mechanism 40, and pieces through and holds, and the leading end of the holding pin 21 approaches and moves to the leading end of a positioning pin 5, and the screw holes 61 of the nuts 60 held on the holding pin 21 are supplied in fitting with the positioning pin 5.
