The invention discloses vacuum heating degassing treatment equipment comprising a framework, a vacuum cavity, a heating plate, an elevating assembly, a horizontal conveying assembly, a vacuumizing system and a control system, wherein an inlet and an outlet are respectively arranged at two ends of the vacuum cavity and are respectively provided with a sealed closing valve; the horizontal conveyingassembly is transversely arranged in the vacuum cavity; the elevating assembly is provided with a plurality of supporting poles and cylinder motors, and the supporting poles freely extend to the inside of the vacuum cavity in a sealing way; the heating plate is installed in the vacuum cavity; the vacuumizing system is communicated with the vacuum cavity; and the heating plate, the elevating assembly, the horizontal conveying assembly and the vacuumizing system are all electrically connected with the control system. The vacuum heating degassing treatment equipment is simple in structure and convenient to operate, effectively prolongs the service life of a display device, plays a buffer role between the outside and a vacuum packaging production line, and does not need to damage the vacuum state of the production line during working.
Description
technical field [0001] The invention relates to a degassing treatment device, in particular to a vacuum heating and degassing treatment device for heating and degassing the rear cover of an organic light-emitting display device before packaging. Background technique [0002] The OLED display uses Organic Light-Emitting Diode (Organic Light-Emitting Diode) as a new type of flat panel display technology, which has been gradually recognized by a large number of manufacturers. However, the development of OLED technology can be said to be not very mature so far, and its display devices still have some shortcomings. At present, the most prominent defect is its short service life. The problem of device life has largely limited the process of OLED display industrialization. . The lifespan of an OLED display depends on the performance and lifespan of the selected organic material on the one hand, and on the other hand the packaging method, packaging equipment and application effect ...
