Abstract

An automatic pick-up equipment adapted to pick up components having different shapes includes a base mounted on a manipulator of a robot, a first pick-up device mounted on the base and including a pair of first gripping mechanisms opposite to each other, and a second pick-up device mounted on the base and including a pair of second gripping mechanisms opposite to each other and a rotation mechanism. The first gripping mechanisms are configured to linearly reciprocate relative to each other to grip a first component. The second gripping mechanisms are configured to pivotally reciprocate relative to each other to grip a second component. The rotation mechanism is configured to drive the second gripping mechanisms to rotate relative to the base to change a posture of the second component.

First claim

What is claimed is:

a first driving device;
a movable block on which the first gripper is mounted, the movable block connected to the first driving device for driving the movable block to move linearly relative to the second gripper; and
a first driving mechanism arranged on the movable block and configured to drive the first gripper to move linearly relative to the second gripper for gripping the first component therebetween; and

a second pick-up device mounted on the base and including a pair of gripping arms opposite to each other and a rotation mechanism, the gripping arms are configured to pivotally reciprocate relative to each other to grip a second component, the rotation mechanism is configured to drive the gripping arms to rotate relative to the base to change a posture of the second component.

2. The automatic pick-up equipment of claim 1 , wherein the base includes a lower support frame mounted on the manipulator and an upper support frame supported on the lower support frame, the first pick-up device is mounted on the upper support frame.

3. The automatic pick-up equipment of claim 2 , wherein the first driving device is mounted between the upper support frame and the lower support frame, the first gripping mechanisms each have a movable block passing through the upper support frame and connected to the first driving device so that the movable blocks are driven to linearly move, and the first and second grippers mounted on a respective one of the movable blocks and cooperating to grip the first component.

4. The automatic pick-up equipment of claim 3 , wherein the first driving device includes a motor and a screw rod connected to an output shaft of the motor, the screw rod is engaged with a meshing part of each of the movable blocks extending between the upper support frame and the lower support frame, so as to drive the movable blocks to linearly move through the screw rod and the meshing parts with the motor.

5. The automatic pick-up equipment of claim 1 , wherein the first driving mechanism has a first pneumatic device configured to drive the first gripper to move relative to the movable block by a gas pressure.

6. The automatic pick-up equipment of claim 1 , wherein the second pick-up device includes an installation portion mounted on the base and a second driving device, the pair of gripping arms include a fixation arm extending from the installation portion and having a first contact surface on an end of the fixation arm, a rotation arm pivotally mounted on the fixation arm and having a second contact surface on a first end of the rotation arm, the second driving device mounted on the installation portion and configured to drive the rotation arm to rotate relative to the fixation arm so as to grip the second component by cooperation of the first contact surface and the second contact surface.

7. The automatic pick-up equipment of claim 6 , wherein the first contact surface and the second contact surface are parallel to each other while gripping the second component.

8. The automatic pick-up equipment of claim 7 , further comprising at least one gas source mounted on the base.

9. The automatic pick-up equipment of claim 6 , wherein the rotation arm is mounted on the fixation arm by a pivotal shaft between the first end of the rotation arm and a second end of the rotation arm opposite to the first end.

10. The automatic pick-up equipment of claim 6 , wherein the rotation mechanism includes a side support frame mounted on a side of the base and a third driving device mounted on the side support frame and configured to drive the installation portion to rotate.

11. The automatic pick-up equipment of claim 10 , wherein the third driving device includes a fixation seat mounted on the side support frame, a rotation shaft rotatably mounted on the fixation seat, the installation portion being mounted on the rotation shaft to rotate with the rotation shaft, and a third driving mechanism configured to drive the rotation shaft to rotate.

12. The automatic pick-up equipment of claim 11 , wherein the rotation shaft has a gear and the third driving mechanism has a rack engaged with the gear and a third pneumatic device configured to drive the rack to linearly move, so as to drive the gear to rotate by the rack.

13. The automatic pick-up equipment of claim 12 , wherein the fixation seat is detachably mounted on the side support frame.

14. The automatic pick-up equipment of claim 6 , wherein the first component has a housing and the second component has a connection terminal, the first pick-up device is configured to fix the housing on an installation table and the second pick-up device is configured to insert the connection terminal into an installation hole in the housing.

15. The automatic pick-up equipment of claim 14 , wherein the connection terminal has a main body and a pair of connection arms extending parallel from the main body, the connection arms each have a first part extending from the main body and a second part substantially perpendicular to the first part, the first parts of the connection arms and the main body define a generally U-shaped opening, the second pick-up device gripping the second part of the connection terminal.

16. An automatic pick-up equipment adapted to pick up components having different shapes, comprising:
a base mounted on a manipulator of a robot;
a first pick-up device mounted on the base and including a pair of first gripping mechanisms opposite to each other, the first gripping mechanisms are configured to linearly reciprocate relative to each other to grip a first component; and
a second pick-up device mounted on the base and including:
a fixation arm having a first contact surface and a rotation arm pivotally mounted to the fixation arm between a first end and a second end of the rotation arm, and having a second contact surface, the fixation arm and the rotation arm arranged opposite to each other and configured to pivotally reciprocate relative to each other to grip a second component;
a rotation mechanism configured to rotate the fixation arm and the rotation arm relative to the base to change a posture of the second component; and
a driving device for rotating the rotation arm relative to the fixation arm so as to grip the second component by cooperation of the first contact surface and the second contact surface, the driving device including a driving mechanism and a tongue portion inserted between the fixation arm and the second end of the rotation arm under drive of the driving mechanism, so as to drive the rotation arm to rotate relative to the fixation arm and move the second contact surface toward the first contact surface.
