Abstract

The present invention provides a transfer device which can position with high accuracy, a surface mounting device, a method for producing an error table, programs, and a storing medium. Before electronic components are mounted on a printed board P, an operation control unit 77a adjusts mounting positions, by taking into account chucking positional offset of electronic components which is calculated by an image processor 73, based on the fetched image of a part recognition camera 6, and also, corrects rotational errors around a Z axis of each head based on an error table 74c.

Description

technical field

[0001] The present invention relates to a transfer device for correcting the rotation error of the head that absorbs electronic components, and transferring the electronic components adsorbed by the head from one position to another, and a surface mounter with the transfer device , a method for generating an error table storing head rotation errors. Background technique

[0002] Conventionally, a surface mounter for mounting electronic components on a printed circuit board and a component inspection device for inspecting electronic components have been equipped with a component transfer device that picks up and transfers components with suction nozzles. This component transfer device consists of a head unit that can move in a horizontal plane, and a suction head mounted on the head unit that can freely rotate on an axis perpendicular to the above-mentioned horizontal plane and freely move in an up and down direction. , the rotation direction drive device tha...
