With the development of LCD in the direction of large size, thinness, low power consumption and high resolution, the size and thickness of glass substrate and related optical components are gradually increasing, which greatly increases the probability of various display defects in LCD screen. Traditional artificial vision inspection methods are easily influenced by subjective factors of inspectors and external environment, so it is difficult to ensure product quality and the inspection efficiency is also low. Therefore, equipment for automatic photo inspection and pixel-level defect identification is designed.

In this project, a manipulator or a person is responsible for taking and placing the board to be tested, putting the product (touch screen) on the docking station and automatically entering the test area. In the test area, the communication connector is automatically inserted into the socket of the touch screen to complete the line connection. After the line connection is completed, all test items are automatically completed by program control, and the test results are transmitted to the manipulator through I/O or network port communication after the test is completed. According to the test results provided by the test equipment, the manipulator places the good products and the bad products in different places.
