Abstract
The present disclosure relates to a gripper and a robot. The gripper according to the present disclosure includes at least three guiding rails arranged head to tail in sequence, at least three gripping fingers respectively disposed on the at least three guiding rails and a driving mechanism. A first end of each of the gripping fingers is slidably connected to the corresponding guiding rail and a second end of each of the gripping fingers is for contacting the object to be gripped. The driving mechanism drives each of the gripping fingers to move along the corresponding guiding rail, so that the second end of each of the gripping fingers moves toward or away from a gripping center of the gripper.
Claims14
A gripper, comprising:
- at least three guiding rails arranged head to tail in sequence;
- at least three gripping fingers respectively disposed on the at least three guiding rails, each of the gripping fingers comprising a first end slidably connected to a corresponding one of the at least three guiding rails and a second end configured to contact an object to be gripped;
- and
- a driving mechanism configured to drive each of the gripping fingers to move along the corresponding one of the at least three guiding rails, so that the second end of each of the gripping fingers moves toward or away from a gripping center of the gripper;
- wherein each of the gripping fingers includes a column portion, a lateral extension portion, and a gripping portion that are connected in sequence, wherein a first end of the column portion forms the first end of each of the gripping fingers and is slidably connected to the corresponding one of the at least three guiding rails through a slider, the lateral extension portion comprising a first end connected to a second end of the column portion and a second end connected to the gripping portion, and the gripping portion forms the second end of each of the gripping fingers;
- and
- wherein the lateral extension portion is inclined relative to the corresponding one of the at least three guiding rails, and the lateral extension portion and the corresponding one of the at least three guiding rails define an obtuse angle range within which the gripping center is located.
A robot comprising a gripper, the gripper comprising:
- at least three guiding rails arranged head to tail in sequence;
- at least three gripping fingers respectively disposed on the at least three guiding rails, each of the gripping fingers comprising a first end slidably connected to a corresponding one of the at least three guiding rails and a second end configured to contact an object to be gripped;
- and
- a driving mechanism configured to drive each of the gripping fingers to move along the corresponding one of the at least three guiding rails, so that the second end of each of the gripping fingers moves toward or away from a gripping center of the gripper;
- wherein each of the gripping fingers includes a column portion, a lateral extension portion, and a gripping portion that are connected in sequence, wherein a first end of the column portion forms the first end of each of the gripping fingers and is slidably connected to the corresponding one of the at least three guiding rails through a slider, the lateral extension portion comprising a first end connected to a second end of the column portion and a second end connected to the gripping portion, and the gripping portion forms the second end of each of the gripping fingers;
- and
- wherein the lateral extension portion is inclined relative to the corresponding one of the at least three guiding rails, and the lateral extension portion and the corresponding one of the at least three guiding rails define an obtuse angle range within which the gripping center is located.
