Abstract

Official abstract text for this publication.

The present invention provides a mechanical arm and a pickup device. The mechanical arm includes a mechanical arm body and a pressure sensing system. The pressure sensing system is fixedly connected with the mechanical arm body, for sensing whether the mechanical arm body is to be collided with a picked-up object.

First claim

Opening claim text (preview).

The invention claimed is: 1. A mechanical arm, comprising a mechanical arm body and a pressure sensing system, wherein the pressure sensing system is fixedly connected with the mechanical arm body, for sensing collision of the mechanical arm body with a picked-up object, and the pressure sensing system is a pressure sensor having a telescopic structure, and when the pressure sensor collides with the picked-up object, the pressure sensor moves in a direction opposite to a movement direction of the mechanical arm. 2. The mechanical arm of claim 1 , further comprising a buffering system, wherein the buffering system is fixedly connected with the mechanical arm body, and an end of the buffering system on a side of the picked-up object is aligned to an end of the pressure sensor on a side of the picked-up object. 3. The mechanical arm of claim 2 , further comprising a protective cap, wherein the protective cap is fixedly connected with the end of the buffering system on a side of the picked-up object and is in contact with the end of the pressure sensor on a side of the picked-up object. 4. The mechanical arm of claim 2 , wherein the buffering system is a hydraulic buffer. 5. The mechanical arm of claim 2 , wherein the mechanical arm body has a hollow structure, an opening is formed in an end of the mechanical arm body on a side of the picked-up object, and the pressure sensing system and the buffering system are fixed in the hollow structure of the mechanical arm body through the opening. 6. The mechanical arm of claim 3 , wherein the material of the protective cap is plastic. 7. The mechanical arm of claim 3 , wherein the picked-up object is a substrate. 8. A pickup device, comprising a mechanical arm, wherein the mechanical arm comprises a mechanical arm body and a pressure sensing system, the pressure sensing system is fixedly connected with the mechanical arm body, for sensing collision of the mechanical arm body with a picked-up object, and the pressure sensing system is a pressure sensor having a telescopic structure, and when the pressure sensor collides with the picked-up object, the pressure sensor moves in a direction opposite to a movement direction of the mechanical arm. 9. The pickup device of claim 8 , wherein the mechanical arm further comprises a buffering system, and the buffering system is fixedly connected with the mechanical arm body, and an end of the buffering system on a side of the picked-up object is aligned to an end of the pressure sensor on a side of the picked-up object. 10. The pickup device of claim 9 , wherein the mechanical arm further comprises a protective cap, and the protective cap is fixedly connected with the end of the buffering system on a side of the picked-up object and is in contact with the end of the pressure sensor on a side of the picked-up object. 11. The pickup device of claim 9 , wherein the buffering system is a hydraulic buffer. 12. The pickup device of claim 9 , wherein the mechanical arm body is has a hollow structure, an opening is formed in an end of the mechanical arm body on a side of the picked-up object, and the pressure sensing system and the buffering system are fixed in the hollow structure of the mechanical arm body through the opening. 13. The pickup device of claim 10 , wherein the material of the protective cap is plastic. 14. The pickup device of claim 8 , wherein the picked-up object is a substrate. 15. The pickup device of claim 8 , further comprising a control unit, wherein the control unit controls the mechanical arm to stop operating according to a sensed pressure signal from the pressure sensing system. 16. The pickup device of claim 15 , wherein the control unit is a PLC. 17. The mechanical arm of claim 2 , wherein the buffering system is a cylinder. 18. The pickup device of claim 9 , wherein the buffering system is a cylinder.
