Abstract

A component mounting device performs measurement of a position of a reference section of a head and measurement of calibration data of the head, and the calibration data of the head and the position of the reference section are stored in association. The component mounting device controls operation of the head holding body in which the head is held based on the calibration data of the head and the position of the reference section. In a case where it is not necessary to generate the calibration data of the predetermined head, the component mounting device measures the position of the reference section, and controls operation of the head holding body in which the head is held based on the measured position of the reference section, the position of the reference section which is stored, and the calibration data of the head.

First claim

1 : A component mounting device comprising:
a head holding body which holds a head that is provided with a component holder which is capable of holding and releasing a component; a controller configured to control an operation of the head holding body; and a storage medium for storing data, wherein the controller determines whether it is necessary to generate calibration data of the head when a predetermined head is held by the head holding body, in a case where it is necessary to generate calibration data of the head, performs measurement of a position of a reference section of the head and measurement of the calibration data of the head, stores the calibration data of the head in the storage medium, and controls operation of the head holding body in which the head is held based on the calibration data of the head and the position of the reference section, and in a case where it is not necessary to generate the calibration data of the head, measures the position of the reference section and controls operation of the head holding device in which the head is held based on the measured position of the reference section and the calibration data of the head which is stored in the storage medium.

2 : The component mounting device according to claim 1 ,
wherein in a case where it is necessary to generate the calibration data of the head, the controller performs measurement of the position of the reference section of the head and measurement of the calibration data of the head, stores the position of the reference section of the head and the calibration data of the head in the storage medium, and controls the operation of the head holding body in which the head is held based on the calibration data of the head and the position of the reference section, and in a case where it is not necessary to generate the calibration data of the head, measures the position of the reference section, and controls the operation of the head holding body in which the head is held based on the measured position of the reference section, the position of the reference section which is stored in the storage medium, and the calibration data of the head which is stored in the storage medium.

3 : The component mounting device according to claim 1 ,
wherein the controller generates the calibration data of the head holding body and stores the calibration data of the head holding body in the storage medium in advance before determining whether it is necessary to generate the calibration data of the head, and controls operation of the head holding body in which the head is held using also the calibration data of the head holding body which is stored in the storage medium.

4 : The component mounting device according to claim 1 ,
wherein the controller determines whether it is necessary to generate the calibration data of the head by determining whether the calibration data of the head is stored in the storage medium.

5 : The component mounting device according to claim 1 , which has a function of automatically exchanging the head which is held in the head holding body with a predetermined head.

6 : A component mounting method comprising:
holding a predetermined head in a head holding body; generating calibration data of the head by performing measurement of a position of a reference section of the head and measurement of the calibration data of the head and storing the calibration data of the head in a storage medium; temporarily removing the head from the head holding body and holding once again in the head holding body; measuring once again the position of the reference section after the head is held once again in the head holding body; and controlling an operation of the head holding body in which the head is held based on the position of the reference section which is once again measured and the calibration data of the head which is stored in the storage medium.
