At present, in the production process of TFT-LCD (Thin Film Transistor Liquid Crystal Display), the Array (array) process is used to form several array panels on a glass substrate. When the number of defective products in the array panels on the glass substrate exceeds a certain When the range is reached, the glass substrate will not enter the next step of the production process and will be discarded directly. The same is true for color filter panels on glass substrates.

Taking the TFT-LCD 5th generation line process as an example, using the Array process, one glass substrate can produce twelve 17-inch array panels. For reasons such as cost, when the defective products of the 12 array panels on the glass substrate When the number is greater than 4, the entire glass substrate is generally thrown away, regardless of the high-quality products contained on the glass substrate. If large-size panels are produced on a higher-level production line, such as a 7th-generation or 8th-generation line, discarded good panels will cause a lot of waste.

In the process of realizing the utility model, the inventor found that there are at least the following problems in the prior art: since there are usually both defective products and good products in the panels on the same glass substrate, the whole glass When the substrate is thrown away, a large number of good products will also be discarded, thereby reducing the utilization rate of the panel.

The top of the telescopic support rod 5 is designed with a round head to prevent the panel from being scratched when touching the panel. After the detector 4 senses the panel, the telescopic support rod 5 starts to catch the panel and support the panel to descend. When the panel touches the bottom of the small unit, the telescopic support rod returns to its original position. The vacuum suction cup 3 starts to fix the panel in the small holding unit.

Wherein, since the panel holding device needs to go through the Cell process, the array panel or color filter panel contained therein is boxed to form a liquid crystal display panel. In order to prevent the panel holding device from being damaged when passing through the Cell process, the The manufacturing material of the panel containing device is an insulating material with high strength and hardness, corrosion resistance and high temperature resistance.
