1. A positioning system for positioning a workpiece, the positioning system comprising:
- a computer;
a first platform;
a second platform arranged on the first platform;
a third platform arranged on the second platform;
a positioning member configured to position the workpiece, the positioning member being arranged on the third platform;
a first driving device secured to the first platform and configured to drive the second platform to move along a first direction;
a second driving device secured to the second platform and configured to drive the third platform to move along a second direction;
a first block comprising a first pressure sensor, the first pressure sensor being configured to detect a first pressure between the first block and the workpiece;
a third driving device secured to the third platform and configured to drive the first block to move along the first direction;
a second block comprising a second pressure sensor, the second pressure sensor being configured to detect a second pressure between the second block and the workpiece;
a fourth driving device secured to the third platform and configured to drive the first block to move along the second direction;
wherein when the first block and the second block comes into contact with the workpiece, the computer is configured to monitor the first pressure and the second pressure, and determines a first distance that the first block has traveled when the first pressure reaches to a first value, and a second distance that second block has traveled when the second pressure reaches to a second value, the computer is configured to control the first driving device and the second driving device to respectively drive the second platform and the third platform to move;
wherein a moving direction and a moving distance of the second platform is determined according to a difference between the first distance and a first standard value, and a moving direction and a moving distance of the third platform is determined according to a difference between the second distance and a second standard value.

Abstract
A positioning system for positioning a workpiece in a desired position is provided. The system includes a first driving device and a second driving device. The first driving device and the second driving device are used to drive the workpiece to move. The system further includes a third driving device and a fourth driving device for driving a first block and a second block to move. The moving direction and moving distance of the workpiece is determined according to a difference between a standard value and a distance that the first block and the second block have travelled.
