Description

Platform handling mechanism and handling storage system

Technical Field

Background

The OLED flexible liquid crystal display is an emerging display technology, and compared with the existing liquid crystal display, the OLED flexible liquid crystal display has the most important characteristics of not only being capable of planar display, but also being capable of bending deformation, so as to realize curved surface display. Compared with the common flat-panel liquid crystal display, the production process flow is greatly simplified, the energy consumption is lower, the service life is longer, and the method is the main stream direction of the development of future display technology.

In the link of OLED LCD production, large and thin flexible substrates need to be precisely carried, and meanwhile, because the layout of products is different, a plurality of different carrying platforms need to be used. So the carrying and storing of the carrying platform also directly influences the production efficiency of the equipment, and further influences the final price of the product.

The conventional carrying and storing method of the platform in the OLED production process is that a storage module of a product platform is independently designed outside a production line, and the carrying and storing of the platform are realized through an independent carrying mechanism. The structure not only occupies more space outside the production line, but also needs to separately design the carrying mechanism, thereby increasing the complexity of the equipment. The transport of platform can not be multiplexing, leads to the operation complicacy, and production efficiency reduces.

The other platform carrying and storing method is that the storage space is shared with the feeding part of the production line, but the platform carrying needs to be separately designed, and the new platform adding needs to be separately designed to be provided with a station, so that the structure can save space although the storage sharing can be realized, but a set of carrying mechanism needs to be separately designed because an adsorption device and a conveying system for multiplexing large sheets are not needed, and the structural complexity is increased. Meanwhile, the platform needs to be replaced by a new station and structure, which finally results in complex operation and low production efficiency.

If the storage plate 73 is fixedly connected with the storage lifting seat 72, the carrying platform 22 on the storage plate 73 is directly pulled into the sandwich plate. If the structure that the storage plate 73 is movably connected is adopted, the storage plate 73 is pulled into the sandwich plate, and the carrying platform 22 placed on the storage plate 73 enters the sandwich plate together.

Step 4, the storage lifting seat 72 is moved to a sandwich plate where the carrying platform 22 needs to be replaced, the push-pull device 75 in the sandwich plate pushes the carrying platform 22 or the storage plate 73 with the carrying platform 22 placed thereon onto the storage lifting seat 72, the storage lifting seat 72 is lifted to a specified position, the lifting hook clamps the carrying platform 22, then the lifting platform 16 is lifted to a specified height, the horizontal moving platform 61 is moved to an adsorption station along the guide rail, the lifting platform 16 is lowered for a certain distance, and the carrying platform 22 is placed on the workbench.

The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
