US 6,684,494 B2 · Parts replacing method and parts replacing apparatus

Abstract

An electronic parts replacing apparatus comprises: a holder for holding a piece of electronic parts to be replaced; a head detachably provided to the holder; and a guide bar for guiding the head to move close to or away from a circuit board. After holding the piece of electronic parts to be replaced on the circuit board by the holder and then integrating the head to the holder, the piece of electronic parts to be replaced are removed by moving the holder to a direction away from the circuit board. After removing the piece of electronic parts to be replaced from the holder and then holding a new piece of replacing electronic parts, the piece of replacing electronic parts are mounted on the circuit board by moving the head close to the circuit board.

Dependent claims

A parts replacing method comprising the steps of:

a positioning step in which a holding section of a parts holding means is positioned over a part to be replaced located on a substrate and in which guide means are positioned relative to the substrate;
a chucking step in which a part holding chuck is positioned on the part to be replaced;
an alignment step in which the holding section and chuck are aligned and oriented for proper coupling by adjustment of their relative positions, if necessary;
a holding step in which said part holding chuck is held by said parts holding means and said part to be replaced is held by said part holding chuck;
a removing step in which said part to be replaced is removed from said substrate by moving said parts holding means away from said substrate, while said parts holding means is guided along a path of travel by guide means;
a replacing step in which said part to be replaced is removed from said part holding chuck and in which a replacement part is then held by part holding chuck and said part holding chuck is held by said holding section of said parts holding means;
and
a mounting step in which said replacement piece held by said part holding chuck is moved closer to said substrate, while said parts holding means is guided along a path of travel by said guide means.
