- the component mounting apparatus 10 includes a plurality of component supply units 20, a plurality of component mounting units 30, a plurality of board recognition cameras 22, and a plurality of component recognition cameras 24. Illustrated, but not limited to.
- the component mounting apparatus 10 may include one component supply unit 20, one component mounting unit 30, one board recognition camera 22, and one component recognition camera 24 instead of multiple units.
- the component mounting section 30 has a plurality of mounting units 34 has been described, but the present invention is not limited to this.
- the component mounting section 30 may have one mounting unit 34 instead of multiple.
- the predetermined error is an error due to a defective sliding state of the holding portion 52 with respect to the lifting portion 38, but the present invention is not limited to this.
- the predetermined error may be an error due to an abnormal flow rate of air blown toward the component 2 when mounting the component 2 on the substrate 1 .
- the detection unit may be a measuring device or the like that measures the flow rate of the air.
- each component may be configured with dedicated hardware or implemented by executing a software program suitable for each component.
