First Claim
1. A component mounting apparatus for mounting a component onto a flat display panel, comprising:
- a transfer device for transferring a flat display panel between processing stations, said transfer device including(i) transfer arms having an upper planar surface, and(ii) suction devices, not defining any portion of said upper planar surface of said transfer arms, for sucking a lower surface of the flat display panel, when the flat display panel is loaded onto said transfer arms, such that the lower surface of the flat display panel is positioned at said upper planar surface of said transfer arms so as to have the flat display panel held on said transfer arms in a state that the lower surface of the flat display panel is in contact with said upper planar surface of said transfer arms.

Abstract
Transfer of liquid crystal panels to subsequent processes is performed with the panels placed on transfer arms and held by suction pads. A small suction force can be sufficient, and a suction irregularity is prevented. The transfer arms are arranged at a lower side of the liquid crystal panels, thus not obstructing the liquid crystal panels. In arranging the liquid crystal panels at an image pickup device, a panel holding device is controlled to be driven so as to position panel marks to a bonding height position while negating a deflection amount of the liquid crystal panels, and furthermore a component holding device is controlled to be driven so as to position component marks to the bonding height position and to mount electronic components to the liquid crystal panels at the bonding height position.
