Abstract
A work head unit that detects the rotational position of suction nozzle with first Q-axis encoder positioned facing component holding section that holds a component. With the work head unit, it is desirable to detect the orientation of component holding section at two locations: suction nozzle and syringe member.
Claims11
A work head unit comprising:
- a component holding section configured to hold a component and be rotatable around a rotational axis, the component holding section including a syringe member and a collecting member configured to collect the component and to be attached to and removed from the syringe member;
- and
- a rotary section holding the component holding section;
- a detection section extending along and facing the syringe member and the collecting member and configured to detect the orientation of the component holding section, wherein
- the detection section includes a first optical type or magnetic type encoder positioned below the rotary section and configured to detect a rotational position of the collecting member, and
- the detection section includes a second optical type or magnetic type encoder positioned above the rotary section and configured to detect a rotational position of the syringe.
A work head unit control method for a work head provided with a rotary section, a component holding section held by the rotary section and configured to hold a component and be rotatable around a rotational axis, the component holding section including a syringe member and a collecting member configured to collect the component and to be attached to and removed from the syringe member, and a detection section extending along and facing the syringe member and the collecting member and configured to detect the orientation of the component holding section, the work head unit control method comprising:
- (a) detecting a rotational position of the collecting member with a first optical type or magnetic type encoder of the detection section positioned below the rotary section;
- (b) detecting a rotational position of the syringe with a second optical type or magnetic type encoder of the detection section positioned below the rotary section;
- (c) a step of correcting an orientation of the component holding section based on by comparing the rotational position of the collecting member and the rotational position of the syringe.
