Abstract:
1. An electronic component mounting apparatus for mounting an electronic component on an electronic component mounting position of a board, said apparatus comprising: an electronic component supplying unit for supplying electronic components by arraying a plurality of said electronic components in a plane shape; a board holding unit arranged at a position separated from said electronic component supply unit along a first direction; a mounting head for picking up an electronic component of said electronic component supplying unit to hold the picked electronic component, and for mounting said held electronic component on an electronic component mounting position of a board held by said board holding unit; a mounting head transporting mechanism for transporting said mounting head between said electronic component supplying unit and said board holding unit; a first camera for taking an image of the board held by said board holding unit; a first camera transporting mechanism for transporting said first camera over at least said board holding unit; a first recognition processing unit for processing an image taken by said first camera so as to acquire an actual position of said electronic component mounting position of the board held by said board holding unit; a second camera for taking an image of the electronic component of said electronic component supplying unit; a second camera transporting mechanism for transporting said second camera over at least said electronic component supplying unit; a second recognition processing unit for processing an image of said second camera so as to acquire a position of the electronic component of said electronic component supplying unit; mounting head transporting control means for controlling said mounting head transporting mechanism so as to execute: (1) a positioning operation of said mounting head in the case that the electronic component is picked up from said electronic component supplying unit based upon the position of the electronic component acquired by said second recognition processing unit, and also in order to perform: (2) a positioning operation of said mounting head in the case that the electronic component is mounted on the board of said board holding unit based upon the actual position of the electronic component mounting position acquired by said first recognition processing unit; first camera transporting control means for controlling said first camera transporting mechanism so as to execute: (1) an image of a positioning operation of said first camera in the case that the board held by said board holding unit is taken, and also in order to perform: (2) an evacuating operation for transporting said first camera to a position where mounting of the electronic component by said mounting head is not disturbed; and second camera transporting control means for controlling said second camera transporting mechanism so as to execute: (1) a positioning operation of said second camera in the case that an image of the electronic component of said electronic component supplying unit is taken, and also in order to perform: (2) an evacuating operation for transporting said second camera to a position where the pick-up operation of the electronic component by said mounting head is not disturbed.
