Claims
- 1. Apparatus adapted for gripping an object, comprising a mounting head; suction-operated gripping means for selectively gripping an object positioned adjacent one side of said gripping means; suction-operated attaching means for selectively and removably attaching said gripping means to said mounting head, whereby said gripping means is removable from said mounting head and is hence replaceable; and viewing means, including a camera, for viewing an object gripped by said gripping means, said viewing means being located on an opposite side of said gripping means, said gripping means having a light-transmitting portion positioned in such a manner that an object gripped by said gripping means can be viewed by said camera through said gripping means, and said camera being independently and selectively movable relative to said mounting head.
- 2. The apparatus of claim 1, further comprising first supplying means for selectively and independently supplying suction to said attaching means and second supplying means for selectively and independently supplying suction to said gripping means.
- 3. The apparatus of claim 2, wherein said attaching means includes a vacuum transfer plate mounted to said mounting head, said vacuum transfer plate including a groove having a side open towards said gripping means such that suction can be applied from said first supplying means to said gripping means through said groove.
- 4. The apparatus of claim 3, wherein said vacuum transfer plate includes a first suction channel formed through said vacuum transfer plate and communicating with said groove, said first suction channel being connected to said first supplying means.
- 5. The apparatus of claim 4, wherein said light-transmitting portion is positioned in the field of view of said camera.
- 6. The apparatus of claim 5, wherein said gripping means includes a chuck having a second suction channel through said light-transmitting portion for gripping an object in response to application of suction from said second supplying means through said second suction channel.
- 7. The apparatus of claim 6, wherein said second supplying means includes a third suction channel extending through said vacuum transfer plate, said third suction channel communicating with said second channel for supplying suction to said second suction channel through said third suction channel.
- 8. The apparatus of claim 7, wherein said viewing means includes a mirror for reflecting the image of an object gripped by said gripping means to said camera, said mirror being movable conjointly with said camera relative to said mounting head.
- 9. The apparatus of claim 8, wherein said viewing means includes a housing for housing said camera and said mirror.
- 10. The apparatus of claim 1, wherein said viewing means includes a mirror for reflecting the image of an object gripped by said gripping means to said camera, said mirror being movable conjointly with said camera relative to said mounting head.
- 11. The apparatus of claim 10, wherein said viewing means includes a housing for housing said camera and said mirror.
