[0003] With the continuous expansion of the application field of LCD screens and the continuous improvement of people's requirements for the quality of LCD screen images, the image detection after the production of LCD screens has become more and more important. In the existing technology, the completion of the inspection requires that the product be loaded onto the crimping mechanism (panel point screen detection equipment) for panel inspection. The crimping mechanism is electrically connected to the test points on the panel to be inspected. After the crimping is completed, the crimped panel to be tested is transported to the inspection mechanism by the transport mechanism for inspection. The display screen is analyzed to determine whether the display panel has defects.
