Abstract

A display panel vacuum suction system includes a control device, a robot arm, and a vacuum device. The robot arm includes two or more retractable rods, and each of the retractable rods is connected with a vacuum plate. Each vacuum chamber is disposed in each of the vacuum plates, and each vacuum hole is disposed on a surface of each of the vacuum plates, wherein each vacuum chamber is connected with the vacuum device by a suction pipe. The control device controls expansion and retraction of the retractable rods of the robot arm, so that the vacuum plates connected with the retractable rods can be combined to pick up a single display panel or pick up two display panels respectively. By combining vacuum plates, and controlling the opening or closing of the vacuum holes of each of the vacuum plates, different sizes of display panels can be sucked.

First claim

What is claimed is:

1. A display panel vacuum suction system, comprising:
a control device, a robot arm, and a vacuum device;
wherein the robot arm comprises two or more retractable rods, and each of the retractable rods is connected with a vacuum plate;
wherein each vacuum chamber is disposed in each of the vacuum plates, and each vacuum hole is disposed on a surface of each of the vacuum plates, wherein each of the vacuum chamber is connected with the vacuum device by a suction pipe;
wherein the control device controls expansion and retraction of the retractable rods of the robot arm, so that the vacuum plates connected with the retractable rods can be combined to pick up a single display panel or pick up two display panels, and
wherein number of the vacuum holes on the vacuum plates is two or more.

2. The display panel vacuum suction system as claimed in claim 1 , wherein the vacuum holes are arranged in two or more rows on the vacuum plates.

3. The display panel vacuum suction system as claimed in claim 1 , wherein a baffle is disposed in each of the vacuum holes; and wherein the control device comprises a switch control circuit for opening or closing the baffles of the vacuum holes, thereby enabling or disabling the suction function of the vacuum holes.

4. The display panel vacuum suction system as claimed in claim 3 , wherein the switch control circuit is disposed in the retractable rods.

5. The display panel vacuum suction system as claimed in claim 1 , wherein each of the suction pipe is disposed in the retractable rod.

6. The display panel vacuum suction system as claimed in claim 1 , wherein a shape of the vacuum plates comprises is selected from the group consisting of a square, a rectangle, a fan, a circle, an ellipse, and a triangle.

7. The display panel vacuum suction system as claimed in claim 6 , wherein the two or more vacuum plates can be combined into one of a complete shape selected from the group consisting of a square, a rectangle, a circle, an ellipse, a triangle, and a polygon.

8. The display panel vacuum suction system as claimed in claim 1 , wherein the robot arm comprises four retractable rods, each of the retractable rods is connected with a fan-shaped vacuum plate, and the four fan-shaped vacuum plates can be combined to form a complete circle or ellipse.

9. The display panel vacuum suction system as claimed in claim 1 , wherein the vacuum suction system comprises two or more robot arms, and each of the robot arms comprises two or more retractable rods.
