A suction unit, which serves for suctioning an object according to Bernoulli's principle, includes a suction body with an adjoining suction plate, which has a front side facing away from the body, and includes at least one entry channel, through which a gaseous medium is introducible through the suction body into a deflection channel, which is delimited on one side by the suction plate and on another by a deflection head of a deflection unit or by the suctioned object, and through which the gaseous medium is guidable to the outside. The suction body is integrally or detachably connected to a suction basket whose inner side adjoins the suction plate or is spaced apart from the plate, wherein the basket encloses a receiving channel which has a channel opening dimensioned so that objects can be introduced into the channel or at least one recess on the underside of the basket.

The suction plate has in the center a deflection chamber which is adjoined on one side by the at least one entry channel and on another side by a plurality of suction channels which are sunk into the suction plate and extend towards the edge of the suction plate.

The invention provides a motion device, including: a tray; a rotary stage located below the tray and with an annular upper cavity provided on the upper surface thereof, and with a lower cavity provided on the lower surface thereof, wherein the projections of the annular upper cavity and the lower cavity in the projection direction perpendicular to the upper surface of the rotary stage are not overlapped with each other; a rotary motor accommodated in the annular upper cavity and including a rotor of the rotary motor and a stator of the rotary motor, the stator of the rotary motor being fixed with respect to the rotary stage, and the rotor of the rotary motor being fixed with respect to the tray; a vertical movable device located in the lower cavity and configured to drive the rotary stage to move vertically; a magnetic levitation gravity offsetting device located in the lower cavity and configured to offset the gravity of the rotary stage. Compared with the prior art, the vertical size of the motion device of the present invention is significantly reduced, and with the application of the magnetic levitation gravity offsetting device, the vertical movement precision of the motion device is significantly improved.

A Bernoulli gripper for ophthalmic lenses includes a gripper body with a first cavity corresponding in shape to an optic zone of an ophthalmic lens and a first channel formed within the gripper body. The first channel penetrates the first cavity at one end and includes a first port in the gripper body at another end of the first channel. The first channel is enabled to supply a fluid medium from the first port to the first cavity at a first velocity such that the ophthalmic lens positioned with the optic zone in proximity to the first cavity is subject to a first pressure force against the first cavity by the Bernoulli effect.

A processing apparatus includes a wafer unloading unit, a wafer table, a frame unloading unit, a frame table, a tape affixing unit, a tape-affixed frame transporting unit, a tape compression-bonding unit, a frame unit unloading unit that unloads a frame unit in which a tape of a tape-affixed frame and the undersurface of a wafer are compression-bonded to each other from the wafer table, a reinforcing portion removing unit, a no-ring unit unloading unit, and a frame cassette table.

The disclosure relates to a gripping device for an end effector of a manipulator for holding a workpiece via its workpiece surface, having a Bernoulli gripping unit, with an outflow unit for discharging a flow from the Bernoulli gripping unit between gripping device and workpiece surface in such a manner that in a region—Bernoulli-negative pressure region—a static negative pressure for holding the workpiece is generatable by the flow, and having a vacuum gripping unit with a suction chamber, wherein in a region delimited by the suction chamber—vacuum negative pressure region—a static negative pressure for holding the workpiece is generatable, wherein the Bernoulli negative pressure region and the vacuum negative pressure region intersect at least in part or wherein the Bernoulli negative pressure region and the vacuum negative pressure region surround one another.

A swirl-flow forming body includes a through-hole; a jetting port that is formed on an inner periphery facing the through-hole; a fluid passage that allows fluid to be discharged into the through-hole via the jetting port so as to form a swirl flow that generates negative pressure for applying suction to a target object; and a flange portion that is formed so as to protrude from the inner periphery, the flange portion allowing passage of fluid to which suction is applied by the negative pressure while preventing the fluid discharged via the jetting port from flowing out of the through-hole towards the target object. The inner periphery is formed so as to guide the fluid discharged via the jetting port, in a direction away from the target object, to be discharged from the through-hole.
