Embodiment Construction

[0021] In order to describe the technical content and structural features of the present invention in detail, further description will be given below in conjunction with the implementation and accompanying drawings.

[0022] see figure 1 and figure 2 , the finely adjustable lifting device 1 of the present invention is used to be installed on a cavity 2 with a vacuum cavity, and the cavity 2 is used to provide a vacuum environment for the packaging of the OLED device and fix it with the outside world. The finely adjustable lifting device 1 of the present invention includes a support plate 11, a driver 12, an adjustment member 14, and a plurality of lifting rods 13. In this embodiment, five lifting rods 13 are selected, and its number is determined by those skilled in the art according to actual conditions. It is selected according to the needs, so its quantity is not limited here. The support plate 11 is located outside the cavity 2 and is parallel to the bottom plate 21 of ...

Abstract

The invention provides a fine-adjustable lifting device which is suitable for being arranged on a vacuum chamber body. The fine-adjustable lifting device comprises a supporting plate, a driver, an adjusting member and a plurality of lifting rods; the supporting plate is positioned outside the chamber body and is parallel to a bottom plate of the chamber body; the lower ends of the lifting rods are all fixed on the supporting plate, and the upper ends of the lifting rods all hermetically extend into the vacuum chamber and form a supporting face for bearing a workpiece; the upper end of the adjusting member is in rotatable blocked connection with the supporting plate, and the lower end of the adjusting member is sleeved threaded connection with an output shaft of the driver; and the driver drives the supporting plate to do a linear reciprocated motion through the adjusting member. Due to the adoption of the adjusting member, on one hand, the fine-adjustable lifting device provided by the invention can carry out accurate fine-adjustment on an OLED (Organic Light Emitting Diode) device encapsulated under a vacuum environment, thereby providing excellent conditions for improving the encapsulation quality of the OLED device and prolonging the service life of the OLED device; and on the other hand, the fine-adjustable lifting device provided by the invention has the advantages of simple structure and lower manufacturing cost.

Description

technical field [0001] The invention relates to a lifting device, in particular to a finely adjustable lifting device. Background technique [0002] OLED stands for Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as Organic Electroluminescence Display (OELD). Because of its thinness, power saving and other characteristics, it has been widely used on the display screen of digital products, and has great market potential. At present, the application of OLED in the world is focused on flat panel display, because OLED is the only one in the application A technology that can be compared with TFT-LCD, OLED is the only display technology that can produce large-size, high-brightness, and high-resolution soft screens among all current display technologies, and can be made into the same thickness as paper. [0003] OLED display screens are different from traditional TFT-LCD display screens in that they do not require a backlight, and use very thin coatings of ...
