Abstract

In a component mounting method and apparatus capable of mounting components on a board having a non-planar component mounting surface, a board holding table in a board holding device is turned based on board holding device information and board information to direct a normal line to a mounting portion on the non-planar component mounting surface in the vertical direction. Thus, after being picked up and moved by a component loading device onto the normal line to the mounting portion, a component can be mounted through a movement of the component loading device in the vertical direction only. Further, compensation amounts for the position of the mounting portion are calculated based on a turn amount, the board holding device information and the board information, and a compensated mounting position is calculated from the compensation amounts and the board information accurately in the horizontal and vertical directions.

Dependent claims

A component mounting method in a component mounting apparatus comprising:

a board holding device having a holding member that, in order to mount a component on a board having a non-planar component mounting surface, holds the board at a holding position on a board holding surface and turns the board;
a board transfer device that loads and unloads the board with respect to the board holding surface of the holding member;
a component supply device that supplies the component to be mounted on the board;
and
a component loading device that picks up the component from the component supply device and moves the component in two orthogonal directions within a horizontal plane and in a vertical direction to mount the component at a mounting portion on the board held at the holding position on the board holding surface;
the component mounting method comprising:
a board information inputting step of inputting board information relating to the position of a positioned portion for positioning the board on the board holding surface and the position of the mounting portion;
a board loading and holding step of loading the board to the holding position on the board holding surface by the board transfer device and of holding the loaded board at the holding position on the board holding surface by holding means provided in the board holding device;
a board turning step of turning the holding member of the board holding device so that a normal line to the mounting portion on the non-planar component mounting surface is directed in the vertical direction, based on board holding device information stored in advance that relates to the position in the board holding device of a turn shaft for the holding member, a positional relation between the turn shaft and the board holding surface and the position of the holding position on the board holding surface, and the inputted board information;
a compensated mounting position calculating step of calculating compensation amounts in the two orthogonal directions within the horizontal plane and the vertical direction for the position of the mounting portion whose normal line is directed in the vertical direction at the board turning step, based on a turn amount of the holding member at the board turning step, the board holding device information and the board information and of calculating a compensated mounting position from the compensation amounts in the two orthogonal directions within the horizontal plane and in the vertical direction and the board information;
and
a component mounting step of mounting the component at the mounting portion on the board based on the compensated mounting position.
