Abstract
A fixture includes a supporting body configured to support a front door panel (workpiece) in an inclined state, a pad capable of being abutted to a plate surface of the front door panel, and a negative-pressure unit serving to bring the plate surface of the front door panel into an attracted state by maintaining an inside of a space enclosed by the plate surface and the pad under negative pressure, while the pad is abutted to the plate surface of the front door panel. This negative-pressure unit can switch between a shutdown state in which an attracted state is not achieved, a weakly attracted state in which the attracted state is achieved with a relatively weak negative pressure, and a firmly attracted state in which the attracted state is achieved with a relatively strong negative pressure.
Claims18
A fixture, comprising:
- a supporting body configured to abut a plate surface of a workpiece to support the workpiece in an inclined state;
- a pad having a base portion and a lip portion protruding from a surface of the base portion to form a ring shape, wherein the lip portion is configured to abut the plate surface of the workpiece supported by the supporting body;
- and
- a negative-pressure unit configured to create a negative pressure within a space enclosed by the plate surface and the pad when the pad is abutted to the plate surface of the workpiece so as to place, the plate surface of the workpiece in an attracted state with the pad, wherein the negative-pressure unit is configured to switch between:
- a shutdown state, in which the attracted state is not achieved;
- a weakly attracted state, in which the attracted state is achieved using a first negative pressure;
- and
- a firmly attracted state, in which the attracted state is achieved using a second negative pressure stronger than the first negative pressure.
A suction pad, comprising:
- a base portion;
- a first suction opening formed in the base portion;
- a lip portion protruding from a surface of the base portion with a first protrusion length;
- and
- a protrusion protruding from the surface of the base port on with a second protrusion length, wherein:
- the first protrusion length is longer than the second protrusion length.
