Abstract
A measurement device that can improve measurement accuracy and increase the number of times of service of a measurement jig. The measurement device includes a movement control section that positions the measurement jig at an instructed position in the transfer direction, an imaging control section that images the positioned measurement jig by the measurement camera and acquires an image data, an image processing section that calculates an actual position of the measurement jig based on multiple measurement marks which are included in the image data, and an error measurement section that measures a positioning error in the transfer direction due to the driving device based on the instructed position and the actual position.
Claims19
A measurement device that measures an operation accuracy of a driving device which moves a component tape that accommodates a plurality of electronic components in a defined transfer direction in a measurement target, the device comprising:
- a camera that has a predetermined visual field;
- and
- circuitry configured to:
- send an instruction value to the driving device to position a measurement tape at an instructed position in the transfer direction, the measurement tape configured to imitate the component tape and having a plurality of measurement marks arranged at a defined interval narrower than a width of the visual field along the transfer direction;
- control the camera to image the positioned measurement tape including the plurality of measurement marks;
- acquire an image data generated by the camera as a result of the imaging;
- acquire a position of a first of the plurality of the measurement marks in a first image of the image data;
- acquire a position of a second of the plurality of the measurement marks in the first image of the image data;
- acquire a position of a third of the plurality of the measurement marks in the first image of the image data;
- acquire a position of a fourth of the plurality of the measurement marks in the first image of the image data;
- calculate an actual position of the measurement tape based on the positions of the first, the second, the third, and the fourth of the plurality of the measurement marks in the first image of the image data;
- and
- measure a positioning error in the transfer direction due to the driving device based on the instructed position and the actual position.
