Problems solved by technology

However, in the actual production process, there may be situations where the position of the manipulator is shifted, etc., so that the substrate 20 will hit the clamp and the substrate will be broken.
Or, before the robot picks up the substrate, the substrate has been broken due to destructive external force during transportation or process
When the substrate is damaged in the lock, and the process machine cannot identify whether it is broken, after the broken substrate enters the process chamber, process risks such as debris will be generated, which will consume a lot of time and manpower to clean the debris, affecting Productivity
[0005] However, the current magazine cannot detect whether the substrate it carries is broken (that is, whether it is complete), so it is urgent to provide a cassette structure capable of detecting the integrity of the substrate and a method for detecting the integrity of the substrate, so as to Solve the above technical problems

Abstract

The invention provides a cartridge structure capable of sensing the completeness of a substrate and a method for sensing the completeness of the substrate. The cartridge structure capable of sensing the completeness of the substrate comprises an outer frame, supporting parts, a sensing unit and a signal processing unit, wherein the supporting parts are arranged on the outer frame at intervals to define an accommodating space for carrying the substrate, the sensing unit is arranged on at least partial supporting parts and generates a sensing signal indicating the completeness of the substrate, the signal processing unit is connected with the sensing unit and processes the sensing signal so as to detect the completeness of the substrate in the cartridge structure, so that the incomplete substrate can be effectively prevented from entering a next step not to threaten the production efficiency and the production safety.

Description

Technical field [0001] The invention relates to the field of display technology, and in particular to a cassette structure capable of detecting the integrity of a substrate and a method for detecting the integrity of the substrate. Background technique [0002] In the production process of the display panel, due to the complicated process and numerous steps, the glass substrate as the substrate needs to go back and forth between relatively independent production equipment many times. In actual production, a cassette capable of carrying multiple substrates is usually used as a carrying device for storing and transporting substrates. [0003] figure 1 Is a schematic diagram of the structure of a cassette in the prior art, figure 2 for figure 1 The front view of the card gate carrier substrate shown, such as figure 1 with figure 2 As shown, the outer frame 10 of the cassette structure is provided with a plurality of supporting members 11 arranged at intervals on opposite sides of th...
