SUCTION DEVICE

Disclosed is a suction device that includes: a main body, a suction nozzle, and an elastic member. A through passage is defined in the main body. One end of the main body is defined as a suction nozzle mounting end. The part of the through passage at the suction nozzle mounting end is defined as an inner cavity. The suction nozzle is movably installed within the inner cavity and connected to the main body and communicated with the passage. The elastic member is disposed within the inner cavity and is operative to provide a pushing force for moving the suction nozzle outward of the inner cavity. The suction device can suck up a product having a convex or concave surface in an effective and smooth manner; meanwhile the deviation resulting from misalignment of the product can be corrected facilitating precise positioning of the product in the production line.
