Abstract
A suction pad includes a body and a sponge member. The body includes a negative pressure chamber, and a plurality of communication passages communicating with the negative pressure chamber. The sponge member includes a plurality of cavities opening toward a workpiece. The cavities communicate with the negative pressure chamber through the communication passages, and flow passage adjustment valves for adjusting a flow passage area are arranged in the communication passages, respectively. The suction pad further includes a pressure detection port for detecting pressure in at least one cavity among the plurality of cavities.
Claims6
A suction pad comprising:
- a body;
- and a sponge member,
- wherein the body includes a negative pressure chamber, and a plurality of communication passages configured to communicate with the negative pressure chamber, and the sponge member includes a plurality of cavities configured to open toward a workpiece and communicate with the negative pressure chamber through the communication passages,
- a flow passage adjustment valve configured to adjust a flow passage area is disposed in each of the communication passages, and when vacuum pressure is generated in the negative pressure chamber and a cavity among the plurality of cavities is not closed by the workpiece, a flow passage area of a communication passage among the communication passages that corresponds to the cavity that is not closed by the workpiece is adjusted to be decreased, and
- the suction pad further comprises a pressure detection port configured to detect pressure in at least one cavity among the plurality of cavities.
