Embodiment 1

[0034] like Figure 1 to Figure 5As shown in the figure, a liquid crystal screen robot handling system includes a robot 1 for handling the liquid crystal screen, a destacking rack 3 arranged on the side of the robot 1 for placing the liquid crystal screen 2 that has not been subjected to damage detection, and used for damage to the liquid crystal screen 2. The inspection rack 4 for inspection, the pallet rack 5 for placing the liquid crystal screen 2 that fails to pass the inspection, and the placing table 6 for placing the liquid crystal screen 2 that has passed the breakage inspection. The front of the inspection rack 4 is provided with a laser that is electrically connected to the robot 1 Sensor 7, robot 1 is provided with end effector 8 for sucking liquid crystal screens 2 of different sizes. In this embodiment, the liquid crystal screen 2 is placed on the detection frame 4, and the detection frame 4 has a limit in the vertical direction for the liquid crystal screen 2; th...

Embodiment 2

[0043] A handling method of a liquid crystal screen robot handling system, comprising the following steps:

[0044] S1: Before the official start of motion, debug the robot 1, so that the center TCP of the robot end coincides with the center of the LCD screen 2, adjust the sensing distance of the laser sensor 7 so that it can only sense the height of the LCD screen 2, and absorb the liquid crystal screen 2. The end effector 8 is adjusted to the horizontal position, such as Image 6 As shown in the figure, the edge of one side of the liquid crystal screen 2 on the end effector quickly approaches the laser sensor 7. When the laser sensor 7 begins to receive the reflected signal, the robot 1 stops moving immediately; it should be noted that the liquid crystal on the end effector The edge of one side of the screen 2 is rapidly approaching the laser sensor 7. When the laser sensor 7 begins to receive the reflected signal, the robot 1 stops moving immediately; because of the precisi...

Abstract

The invention discloses a liquid crystal screen robot handling system, comprising a robot for liquid crystal screen handling, a destacking rack arranged beside the robot for placing liquid crystal screens that have not been subjected to damage detection, and a detection rack for liquid crystal screen damage detection , A palletizing rack for placing LCD screens that fail to pass inspection, and a placing table for placing LCD screens that have passed damage detection. The front of the inspection rack is provided with a laser sensor that is electrically connected to the robot, and the robot is provided with liquid crystals of different sizes. screen end effector. The setting of the detection frame and the laser sensor facilitates positioning compensation during the process of transporting the LCD screen on the detection frame to the placement table, so as to meet the positioning accuracy requirements of the LCD screen placed on the placement table. Through the arrangement of the end effector, the liquid crystal screen robot handling system can carry liquid crystal screens of different sizes, which improves the versatility of the liquid crystal screen robot handling system.

Description

technical field [0001] The present invention relates to the technical field of handling, and more particularly, to a liquid crystal screen robot handling system and a handling method thereof. Background technique [0002] As we all know, the development trend of the flat panel display industry is very rapid, which brings huge opportunities to the development of our country. In 2019, my country became the world's largest flat panel display production base, and the production capacity share of large-size LCD screens has also surpassed that of South Korea, the traditional LCD screen manufacturing powerhouse, and the market scale continues to expand. But at the same time, it also brought challenges. my country's robot industry and flat panel display industry both started late, and there is still a big gap with the advanced level of foreign countries. At present, as far as the research status of domestic LCD screen robot handling systems is concerned, certain achievements have ...
