Heating container capable of detecting and preventing leakage of high-temperature metallic material and manufacturing method thereof

Abstract

The invention relates to a heating container capable of detecting and preventing the leakage of a high-temperature metallic material and a manufacturing method thereof. The heating container comprises an internal heating container for containing the metallic material, an external heating container and a detection device, wherein multiple segments of bottom conductive wires are arranged at a position, close to the junction of the bottom and the side surface of the internal heating container, between the internal heating container and the external heating container, two ends of each segment of bottom conductive wire are respectively connected with corresponding detection terminals located at the tops of the internal heating container and the external heating container by virtue of the corresponding conductive wires, and the detection device is used for detecting the leakage of the materials in the internal heating container by detecting the resistance between two detection terminals corresponding to two adjacent ends of two adjacent segments of bottom conductive wires. The invention also provides a manufacturing method of the heating container. The special design of the heating container provided by the invention is easy to detect whether the leakage of the heating container occurs or not and ensure the continuous conduction of related experiments and production in the case that the heating container is broken.

Description

technical field [0001] The invention relates to a heating container, in particular to a heating container capable of detecting and preventing leakage of high-temperature metal materials and a manufacturing method. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) has the advantages of all solid state, ultra-thin, no viewing angle limitation, fast response, room temperature operation, easy realization of flexible display and 3D display, etc., and is unanimously recognized as the mainstream technology of next-generation display. At present, the main method of OLED device production is heating evaporation coating, which mainly uses a heating container to heat the evaporation material in a vacuum environment, so that the sublimation or molten evaporation material is vaporized at a high temperature and deposited on a TFT structure or an anode. structure on the substrate. [0003] In the existing evaporation process, the mode of heati...
