GRIPPER BASE AND GRIPPER SYSTEM

Abstract

A gripper base is provided, including a housing, a movable member, an elastic member, a position restricting mechanism, a guiding rod, and an engaging member. The elastic member is connected to the housing and the movable member. The position restricting mechanism is disposed on the movable member, and includes a groove and a block, wherein the groove surrounds the block. The groove has a top surface, and the block has an upper surface facing the top surface. The top surface has a protrusion protruding toward the block, and the upper surface has a concave structure. One end of the guiding rod is pivotally connected to the housing, and the other end of the guiding rod enters the groove. The engaging member is pivotally connected to the movable member.

Description

Claims

1. A gripper base, comprising: a housing;a movable member;an elastic member, connected to the housing and the movable member;a position restricting mechanism, disposed on the movable member, comprising: a groove, having a top surface; anda block, having an upper surface facing the top surface, wherein the groove surrounds the block, the top surface has a protrusion protruding toward the block, and the upper surface has a concave structure;a guiding rod, wherein one end of the guiding rod is pivotally connected to the housing, and another end of the guiding rod enters the groove; andan engaging member, pivotally connected to the movable member.

2. The gripper base as claimed in claim 1, wherein the protrusion has a top end, the concave structure has a bottom end, and the movable member is movable along a first axis relative to the housing, wherein as seen from the first axis, a distance is formed between the top end and the bottom end.

3. The gripper base as claimed in claim 1, wherein the protrusion has a first bottom end and a second bottom end, and the movable member is movable along a first axis relative to the housing, wherein as seen from the first axis, the first bottom end overlaps the concave structure, and the second bottom end is separated from the concave structure.

4. The gripper base as claimed in claim 3, wherein the groove has an inclined surface connected to the first bottom end and inclined relative to a second axis, and the second axis is substantially perpendicular to the first axis.

5. The gripper base as claimed in claim 1, wherein the block further comprises a lower surface opposite to the upper surface, and the movable member is movable along a first axis relative to the housing, wherein the lower surface is inclined relative to a second axis, and the second axis is substantially perpendicular to the first axis.

6. The gripper base as claimed in claim 1, wherein the gripper base further comprises a driving member disposed on the housing, wherein when the guiding rod is in a first position of the groove, the engaging member is at a closed angle relative to the housing, and when the guiding rod moves from the first position to a second position of the groove, the driving member contacts and pushes the engaging member, and the engaging member rotates from the closed angle to an open angle.

7. The gripper base as claimed in claim 6, wherein the concave structure has a bottom end, and when the guiding rod is in the second position of the groove, the guiding rod is in contact with the concave structure and adjacent to the bottom end.

8. The gripper base as claimed in claim 1, wherein the gripper base further comprises a guiding member, disposed on the housing and having a guiding slot, wherein the movable member has a sliding portion, slidably disposed in the guiding slot.

9. The gripper base as claimed in claim 8, wherein the gripper base further comprises a plurality of balls, and the balls are in contact with the movable member and the sliding portion.

10. A gripper system, comprising: a gripper device;at least one connecting member, disposed on the gripper device;at least one claw flake, having a protruding portion;a second connecting member, disposed on the claw flake, wherein the flake is detachably connected to the gripper device via a magnetic attracting force between the first connecting member and the second connecting member; anda gripper base, comprising: a housing;a movable member;an elastic member, connected to the housing and the movable member;a position restricting mechanism, disposed on the movable member, comprising: a groove, having a top surface; anda block, having an upper surface facing the top surface, wherein the groove surrounds the block, the top surface has a protrusion protruding toward the block, and the upper surface has a concave structure;a guiding rod, wherein one end of the guiding rod is pivotally connected to the housing, and the other end of the guiding rod enters the groove; andan engaging member, pivotally connected to the movable member;wherein when the gripper device brings the claw flake to move toward the gripper base along a first axis, the claw flake contacts and pushes the engaging member from an open angle to a closed angle, and the engaging member affixes the claw flake to the gripper base.

11. The gripper system as claimed in claim 10, wherein when the engaging member affixes the claw flake to the gripper base, and the gripper device moves away from the gripper base, the claw flake is separated from the gripper device.
