Robot breaking-off control method for liquid crystal glass substrate

Abstract

The invention discloses a robot severing control method for a liquid crystal glass substrate. The robot severing control method comprises the following steps that a motion control program sends an encoder zero clearing request signal; after zero clearing, the motion control program repeatedly sends an encoder zero clearing pulse, and the plate severing robot moves to a HOME position to wait for a signal of a waiting position; the plate severing robot moves to a waiting position; after a following starting signal is received, the plate breaking robot follows a program to be started, and after the plate breaking robot approaches a following grabbing position, the plate breaking robot synchronously moves downwards along with the glass; after the plate severing robot receives the plate severing permission and vacuum establishment success signals, the plate severing robot completes the plate severing action around the coordinate system; and after a plate severing completion signal is received, the plate severing action is stopped, and the moving speed in the vertical direction is properly increased to accelerate separation from the dangerous area. Smooth movement control of the severing robot in the whole severing process is guaranteed, the movement flexibility of the severing robot in the process is improved, the robot severing yield of liquid crystal glass substrates is improved, and the production efficiency of the glass substrates is improved.

Description

technical field [0001] The invention belongs to automation technology, in particular to a method for controlling a liquid crystal glass substrate by a robot breaking it. Background technique [0002] With the popularity and widespread use of liquid crystal displays such as mobile phones, tablets, computers, and televisions, the demand for liquid crystal glass substrates is also increasing day by day. According to the data of the Liquid Crystal Branch of the China Optical Optoelectronics Industry Association, in 2020, my country's demand for glass substrates of 8.5 generations and above will exceed 300 million square meters, accounting for 49.6% of the global overall demand. It is necessary to develop advanced production technology capabilities that are compatible with it. [0003] In the production of liquid crystal glass substrates, forming is the most important step in production, and breaking the plate is the most critical action in the forming process. The horse boiling...

Problems solved by technology

Although robots have been widely used in industrial production fields such as automobiles at present, due to the high temperature and high humidity at the mouth of the boiler furnace, the film is very easy to break. Unreasonable robot breaking action process may cause but not limited to breakage board, yield reduction, equipment failure and other issues, which in turn affect the quality of glass products
