Embodiment Construction

[0027] exist figure 1 A gripping device 1 for an end effector 2 of a manipulator 3 for handling a workpiece 4 on a workpiece surface 5 of the workpiece is shown in FIG. With the proposed gripping device 1 it is possible in principle to handle every workpiece 4 which can be gripped on its workpiece surface 5 by means of a static vacuum. The workpiece 4 can be any workpiece with a corresponding workpiece surface 5 .

[0028] A dimensionally stable or also flexible workpiece 4 can be held by the gripping device 1 . These soft materials can be, in particular, aluminum sheets or foils and / or fiber materials, in particular fiber mats. The fiber material may be a dry fiber material and / or a pre-impregnated fiber material.

[0029] According to the proposal, the gripping device 1 has a Bernoulli gripping unit 6 . This Bernoulli gripping unit 6 has an outflow unit 7 for leading the air flow from the Bernoulli gripping unit 6 between the gripping device 1 and the workpiece surface 5...

Abstract

The invention relates to a gripping device for an end effector (2) of a manipulator (3) for retaining a workpiece (4) over the workpiece surface (5) of said workpiece, comprising a Bernoulli grippingunit (6), which has an outflow unit (7) for discharging a flow (SB) from the Bernoulli gripping unit (6) between the gripping device (1) and the workpiece surface (5) in such a way that a static negative pressure can be produced in a delimited region - the Bernoulli negative-pressure region (8) - by means of the flow (SB) in order to retain the workpiece (4), and comprising a vacuum gripping unit(9), which has a suction chamber (10), wherein a static negative pressure can be produced in a region delimited by the suction chamber (10) - the vacuum negative-pressure region (11) - in order to retain the workpiece (4), wherein the Bernoulli negative-pressure region (8) and the vacuum negative-pressure region (11) at least partially coincide or wherein the Bernoulli negative-pressure region (8)and the vacuum negative-pressure region (11) surround each other.

Description

technical field [0001] The invention relates to a gripping device for an end effector of a manipulator according to claim 1 , an end effector for a manipulator according to claim 11 and an end effector according to claim 13 The manipulator described above. Background technique [0002] Different types of gripping devices for end effectors of manipulators are known from the prior art. Vacuum gripping devices usually have a suction chamber in which a static underpressure is generated for holding the workpiece. The negative pressure can be generated according to the Venturi principle or by means of a negative pressure source. Vacuum gripping devices mostly hold workpieces. The workpiece is then immobile relative to the gripping device during holding. The Bernoulli gripper, on the other hand, generates an air flow between the gripper and the workpiece in such a way that an underpressure for holding the workpiece between the Bernoulli gripper and the workpiece is generated. ...
