Component mounting device, offset value calculation method, and offset value calculation program

Abstract

Detect the nozzle offset value. [Solution] A component mounting device has a first nozzle having a first end and a second end at its lower part. In the offset value calculation process, the control device performs the following steps: moves the first nozzle to a first contact position in which the first end of the first nozzle contacts the upper surface of a first component installed in the component mounting section, and detects a first height position, which is the height position of the first nozzle at the first contact position, using a first position detection device; moves the first nozzle to a second contact position in which the second end of the first nozzle contacts the upper surface of a first component installed in the component mounting section, and detects a second height position, which is the height position of the first nozzle at the second contact position, using the first position detection device; and calculates an offset value, which is the difference between the first height position and the second height position.
