Collection support device and collection support method

A collection support device comprising:

• a track unit that includes a conveyance path configured to convey a component discharged from a component case accommodating the component in a bulk state to a supply region in which the component is collectable by a component mounter;
• a cavity unit that includes multiple cavities in the supply region, each of the cavities being configured to accommodate one of the components conveyed from the conveyance path to the supply region in the track unit;
• a storage section configured to store a position of a second cavity in the cavity unit and an image feature value enabling identification of an erroneous detection portion that is erroneously detected as the component in a second image obtained by capturing the second cavity in association with each other in a storage device, for each of the second cavities which are at least one of the multiple cavities and for which it is confirmed that the component is not collectable by the component mounter;
• and
• a decision section configured to decide whether the component is accommodated in the second cavity, based on a degree of matching between the image feature value enabling identification of an inspection target portion detected as the component in an inspection image obtained by capturing the second cavity after accommodation of the component in the second cavity is attempted for supplying the component and the image feature value enabling identification of the erroneous detection portion stored in the storage device, for each of the second cavities.

A collection support method applied to a component collection of a bulk feeder including a track unit that includes a conveyance path configured to convey a component discharged from a component case accommodating the component in a bulk state to a supply region in which the component is collectable by a component mounter, and a cavity unit that includes multiple cavities in the supply region, each of the cavities being configured to accommodate one of the components conveyed from the conveyance path to the supply region in the track unit, the collection support method comprising:

• an image capturing step of capturing a first cavity during a capturing available period in which it is expected that the component is not accommodated in the first cavity, for each of the first cavities which are at least one of the multiple cavities and for which it is confirmed that the component has been collected by the component mounter;
• an updating step of updating a reference image obtained by capturing an empty cavity in which the component is not accommodated, using a first image obtained by capturing the first cavity by the image capturing step, for each of the first cavities;
• and
• a determination step of determining whether the component is accommodated in the first cavity, using the reference image updated by the updating step.
