Abstract

A test gripper is provided that decreases an equipment cost and increases a test precision by integrating and simplifying a jig and a test apparatus into the gripper. The test gripper is configured to align and test a component and includes a frame that has a mounting part installed on a robot arm. In addition, a plurality of pins are installed on the frame and are fitted into apertures of the component to align the component and the test gripper. A measuring sensor is also installed on the frame and is configured to test a precision of the component.

First claim

What is claimed is:

1. A test gripper aligning and testing a component, comprising:
a frame including a mounting part installed on a robot arm;
a plurality of pins installed on the frame and fitted into apertures of the component to align the component and the test gripper;
a measuring sensor installed on the frame and configured to test a precision of the component;
a pin module arm is installed in the frame, the plurality of pins are installed on the pin module arm, and the number of pins is two or more;
wherein the plurality of pins are installed to be movable in a lengthwise direction of the pin module arm along a rail installed on the pin module arm; and
wherein the plurality of pins are installed on a moving part to be moved along the rail by a transfer apparatus.

2. The test gripper according to claim 1 , wherein an apparatus vertically moving the pin is installed on the moving part.

3. The test gripper according to claim 1 , wherein a measuring module arm is installed on the frame and the measuring sensor is installed on the measuring module.

4. The test gripper according to claim 3 , wherein the measuring module arm is installed to be rotatable with respect to the frame.

5. The test gripper according to claim 4 , wherein the measuring module arm is rotated by a motor installed in the frame.

6. The test gripper according to claim 4 , wherein a vertical rail is installed on the measuring module arm in a direction perpendicular to a lengthwise direction of the measuring module arm and is in parallel with a rotation axis of the measuring module arm, and the measuring sensor is transferred along the vertical rail by a vertical transfer apparatus.

7. The test gripper according to claim 6 , wherein a horizontal rail is installed in the lengthwise direction of the measuring module arm, and the vertical rail is moved along the horizontal rail by a horizontal transfer apparatus.

8. The test gripper according to claim 3 , wherein a horizontal rail is installed at the measuring module arm in a lengthwise direction of the measuring module arm, and the measuring sensor is moved by a horizontal transfer apparatus along the horizontal rail.

9. A component test method using the test gripper according to claim 1 , comprising:
allowing the test gripper to approach a fixed component;
fitting the pin into the aperture of the component to align the component and the test gripper; and
testing a precision of the component using the measuring sensor.

10. The component test method according to claim 9 , wherein the method includes lowering the pin with respect to the gripper to fit the pin into the aperture.

11. The component test method according to claim 9 , wherein the method includes installing a measuring module arm on the frame and the measuring sensor on the measuring module.

12. The component test method according to claim 11 , wherein the method includes adjusting a position of the measuring sensor based on rotation of the measuring module arm.

13. The component test method according to claim 12 , wherein the method includes adjusting the position of the measuring sensor based on movement in a vertical direction perpendicular to a lengthwise direction of the measuring module arm and a lengthwise direction of a measuring direction.

14. The component test method according to claim 9 , wherein the method includes installing a pin module arm in the frame, two or more pins on the pin module arm.

15. A test gripper aligning and testing a component, comprising:
a frame including a mounting part installed on a robot arm;
a plurality of pins installed on the frame and fitted into apertures of the component to align the component and the test gripper;
a measuring sensor installed on the frame and configured to test a precision of the component;
a pin module arm is installed in the frame, the plurality of pins are installed on the pin module arm, and the number of pins is two or more;
wherein the plurality of pins are installed to be movable in a lengthwise direction of the pin module arm along a rail installed on the pin module arm;
wherein the plurality of pins are installed on a moving part to be moved along the rail by a transfer apparatus; and
wherein an apparatus vertically moving the pin is installed on the moving part.

16. A test gripper aligning and testing a component, comprising:
a frame including a mounting part installed on a robot arm;
a plurality of pins installed on the frame and fitted into apertures of the component to align the component and the test gripper;
a measuring sensor installed on the frame and configured to test a precision of the component;
a in module arm is installed in the frame, the plurality of pins are installed on the pin module arm, and the number of pins is two or more;
wherein the plurality of pins are installed to be movable in a lengthwise direction of the pin module arm along a rail installed on the pin module arm;
wherein the plurality of pins are installed on a moving part to be moved along the rail by a transfer apparatus; and
wherein a measuring module arm is installed on the frame and the measuring sensor is installed on the measuring module.
