Description

[Technical Field]

[0001] This invention relates to a pick-and-place device that can automatically adjust its size, and more particularly to an arm device for picking and placing jigs and plates with upper and lower covers. [Previous Technology]

[0002] Existing fixtures may include an upper cover and a lower cover. The fixture can be used to place plates to facilitate the transport of the plates. The fixture and plates can be picked up and transferred by a robotic arm. However, existing robotic arms can only be used for fixtures of a single specification and cannot be used for fixtures of different sizes, which inevitably causes inconvenience in use. [Summary of the Invention]

[0003] The technical problem to be solved by the present invention is to provide a pick-and-place device that can automatically adjust its size to meet the shortcomings of the prior art. It is applicable to jigs of different sizes and is used to pick up and place jigs and plates.

[0004] To solve the above-mentioned technical problems, the present invention provides a pick-and-place device that can automatically adjust its size, which can be used for picking up and placing jigs. The jig includes an upper cover and a lower cover. The pick-and-place device includes: a fixed base; a movable base; at least one first power source, which is disposed on the fixed base and the movable base is connected to the first power source. The first power source can push the movable base; at least two fastening members, which are respectively disposed on the fixed base and the movable base; and a plurality of suction cups, which are respectively disposed on the fixed base and the movable base. The first power source can push the movable base, so that the distance between the two fastening members disposed on the fixed base and the movable base changes, so that the two fastening members can be used to hold jigs of different sizes, and the suction cups can pick up the jig.

[0005] Preferably, a second power source is provided on the fixed seat and the movable seat respectively, and the two fasteners are respectively connected to the two second power sources. The two second power sources can respectively push the two fasteners to move in a direction that is closer to or farther away from each other, so as to change the distance between the two fasteners.

[0006] The beneficial effect of the present invention is that the automatically adjustable size pick-and-place device provided by the present invention includes a fixed base, a movable base, at least one first power source, at least two fastening members, and a plurality of suction cups. The first power source is disposed on the fixed base, and the movable base is connected to the first power source. The two fastening members and the suction cups are disposed on the fixed base and the movable base. The first power source can push the movable base, causing the two fastening members disposed on the fixed base and the movable base to change their spacing, so that the two fastening members can be used to fasten jigs of different sizes, and the suction cups can pick up the jigs. Therefore, the pick-and-place device of the present invention can automatically adjust its size and is applicable to jigs of different sizes for picking up and placing jigs and plates.

[0007] Furthermore, the present invention may also provide a second power source on the fixed base and the movable base respectively, and the two fastening members are respectively connected to the two second power sources. The two second power sources can respectively push the two fastening members to move in the direction of approaching or moving away from each other, so as to change the distance between the two fastening members, so that the two fastening members can be adjusted independently, and the adjustability can be increased more effectively, so as to use the two fastening members to fasten jigs of different sizes.
