Method and apparatus for press-fitting caps on electronic parts and the like

An apparatus for press-fitting caps on electronic parts and the like, comprising;

• a rod feeding device for feeding component rods of electronic parts;
• a rod conveying wheel provided on its circumference with lateral grooves disposed at predetermined intervals and adapted to receive and convey said rods fed from said rod-feeding device;
• a device for feeding caps;
• a pair of cap conveying wheels each provided on one side of its circumference with lateral grooves disposed at predetermined intervals so as to receive and convey the caps fed from said cap-feeding device;
• said cap conveying wheels being arranged symmetrically and obliquely with respect to said rod conveying wheel on opposite sides thereof so that the lower ends thereof come in contact with the lower end of said rod conveying wheel, thereby press-fitting the caps on both ends of the respective rods to form rod and cap assemblies;
• a rod and cap assembly take-up wheel positioned adjacent the lower end of the rod conveying wheel and provided on its circumference with lateral grooves disposed at predetermined intervals for receiving the rod and cap assemblies from said rod conveying wheel one-by-one;
• press rollers provided at both sides of and in the vicinity of said wheel for completely press-fitting the caps on the rods by externally pressing both ends of the respective rod and cap assemblies while being conveyed by said take-up wheel;
• and a drive means for rotating all of said wheel in synchronization with one another and at the same circumferential speed.
