Turnover device

Abstract

The invention discloses a turnover device which comprises a top plate, a bottom plate, a baffle plate and two side plates. The top plate and the bottom plate are arranged in parallel; the two side plates are arranged between the top plate and the bottom plate in parallel and are vertical to the top plate and the bottom plate; the top plate, the bottom plate and the side plates form a base plate loading cavity with two openings; the baffle plate is arranged between the top plate and the bottom plate, is positioned at one of the two openings and is vertical to the side plates; a base plate inlet-outlet for the base plate to pass in and out is formed on the other opening; the side plates are provided with a plurality of supporting bodies extending in a footstep shape towards the base plate loading cavity; an upper supporting face for supporting the base plate is formed on the upper surface of each supporting body and slantwise arranged downwards facing to the direction of the base plate loading cavity; and all face combining parts of the support bodies are circular beads. The turnover device is used for loading and turning over the base plate in OLED production, ensures that the base plate is less polluted and not easily scraped in the turnover process and buffers the centralized action of the internal stress of the base plate, thereby ensuring little deformation of the base plate and improving the rate of good product of the base plate.

Description

technical field [0001] The present invention relates to a turnaround device, in particular to a turnaround device for carrying and turning around a substrate with a preset length in the production of display devices. Background technique [0002] With the development of digital entertainment and multimedia technology, display has become an indispensable part of people's life, such as thin film transistor liquid crystal display (TFT-LCD), due to its light and thin characteristics, in addition to the replacement effect on the existing market , new application fields have also emerged, including portable products, information products and video products; after entering the 21st century, with the increasingly severe international energy situation, consumers' awareness of energy conservation and environmental protection has gradually increased. Therefore, the research and development of low energy consumption and pollution-free green energy-saving technology has become the innova...

Problems solved by technology

[0003] In an existing turnover device for storing and transporting substrates, multiple substrates are placed in the substrate turnover device in an upright manner. The substrate turnover device is placed upright on a horizontal workbench, and multiple substrates are placed upright during operation The substrate is not easy to take out; in the process of transportation, due to vibration, it is easy to cause the substrate to fall

Another type of turnover device is to place the substrate horizontally. As shown in Figure 1, the support part 31' of this turnover device is arranged horizontally. There are two problems in this way: one is that the supporting part 31' is set horizontally, and there is a lot of dust on it. After the substrate 50' is placed on the horizontal plane of the supporting part 31', the dust on the horizontal surface will cause the substrate 50' to be affected. Second, when the size of the substrate 50` is large, the substrate 50` will be slightly deformed due to the effect of gravity, causing the edge of the substrate 50` to warp. The contact surface of the part 31' is reduced, that is, the surface contact before deformation becomes the line contact after deformation. Since the support part 31' is not processed, it is easy to scratch the substrate 50'; Large internal stress concentration causes irregular deformation, which eventually reduces the yield of the substrate 50`, and the substrate 50` is easy to drop during transportation
