Claims (9)

An apparatus for detecting a holding position of an electronic circuit component by a component holder,
A reference member provided with a second reference part capable of acquiring a relative position with respect to the first reference part at a position deviated from the first reference part set in advance in the component holder;
An imaging device that images the second reference portion and the electronic circuit component held by the component holder;
An image processing device that acquires the holding position of the electronic circuit component by processing an image acquired by the imaging device;
And a reference member moving device that moves the reference member relative to the component holder.   The first reference portion includes a holder reference line preset in the component holder, and the holding position detection device includes a holder rotation device that rotates the component holder about a holder rotation axis, and the holding The holding position detection device according to claim 1, wherein a tool reference line is the holding tool rotation axis.   The first reference portion includes a holder reference line preset in the component holder, and the reference member moving device includes a reference member rotation device that rotates the reference member around the holder reference line. The holding position detecting device according to claim 1 or 2.   The first reference portion includes a holder reference line preset in the component holder, and the reference member moving device moves the reference member in a radial direction of a circle centering on the holder reference line. 4. The holding position detecting device according to claim 1, further comprising a direction moving device.   The first reference portion includes a holder reference line preset in the component holder, and the reference member moving device is a parallel direction moving device that moves the reference member in a direction parallel to the holder reference line. 5. The holding position detecting device according to claim 1, further comprising:   An interference determination unit that determines whether or not the electronic circuit component held by the component holder interferes with the reference member, and the reference member moving device detects the reference when the interference determination unit determines that interference occurs. 6. The holding position detecting device according to claim 1, wherein the member is moved to a position where the member does not interfere with the electronic circuit component. A reference member position acquisition device that acquires a position of the second reference portion relative to the first reference portion and supplies information relating to the position to the image processing device, and the image processing device acquires the reference member position; The holding position detection device according to claim 1, wherein the holding position of the electronic circuit component is acquired based on information on the position of the reference member supplied from the device and an image captured by the imaging device. . The reference member moving device further includes:
A driving device;
A feedback control device for controlling the drive device to bring the actual position of the reference member acquired by the reference member position acquisition device closer to the target position of the reference member;
The holding position detecting device according to claim 7 including: The image processing apparatus acquires the holding position of the electronic circuit component based on information about the position of the reference member acquired by the reference member position acquisition apparatus at the moment when the imaging apparatus captures an image. The holding position detection device described.
