Abstract
A device capable of separating a remnant from a product part irrespective of a shape of the remnant. The device includes a first attraction part which attracts a first part and is moved downward; a second attraction part provided movable relative to the first attraction part to attract a second part; a jig which comes into contact with a back surface of the second part to prevent the second part from moving downward; and further a position maintaining part which maintains a position of the second attraction part relative to the first attraction part when the first attraction part is moved downward to separate the first part from the second part.
Claims4
A robot comprising:
- a device for untangling parts of a substrate, the device comprising:
- a base;
- a movable part movably mounted to the base so as to be movable relative to the base between a first position and a second position;
- a first attraction part fixed to the base, and having a first attraction surface arranged in a first plane, the first attraction surface configured for attracting a first part of the substrate;
- a second attraction part fixed to the movable part, and having a second attraction surface arranged in a second plane, the second attraction surface configured for attracting a second part of the substrate, the first plane and the second plane being coplanar when the movable part is arranged at the first position, while the first plane is separated from the second plane in a direction toward the first position from the second position when the movable part is arranged at the second position;
- a jig configured for contacting the second part of the substrate from a side of the substrate opposite to the second attraction part;
- and
- a position maintaining part configured for maintaining the movable part at the second position with respect to the base;
- and
- a robot arm connected to the base, the robot arm configured to move the base in a state where the movable part is arranged at the first position, and cause the first attraction surface to contact the first part of the substrate together with causing the second attraction surface to contact the second part of the substrate while the second part of the substrate is contacting the jig,
- wherein the first attraction part is configured to attract the first part of the substrate at the first attraction surface and the second attraction part is configured to attract the second part of the substrate at the second attraction surface when the first attraction surface and the second attraction surface contact the first part of the substrate and the second part of the substrate, respectively.
