Structure of large-size vacuum laminating cavity

Abstract

The invention discloses a structure of a large-size vacuum laminating cavity, and belongs to the technical field of vacuum laminating, the structure of the large-size vacuum laminating cavity comprises an upper-layer pressing box and a lower-layer bearing box, the lower-layer bearing box is arranged below the upper-layer pressing box, and a lower pressure spring column is arranged at the bottom of the upper-layer pressing box; the bottom of the lower pressure spring column is fixedly connected with a steel plate, the top of the lower-layer bearing box is fixedly connected with an operation panel, the operation panel and the lower-layer bearing box are integrally formed, and the top of the operation panel is fixedly connected with bakelite; the cambered surface design of the vacuum laminating platform mainly aims at OCA large-size lamination larger than or equal to 20 inches, the problem that laminating bubbles are poor and are the first big problem of large-size OCA lamination is solved, the ingenious design of the laminating platform is overcome by arranging mechanisms such as bakelite, a steel plate, a lower compression spring column and a laminating center point, and the maximum economic benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of vacuum lamination, more specifically, it relates to a structure of a large-size vacuum lamination chamber. Background technique [0002] With the G6 line (1850*1500mm) LTPS technology will be mainly introduced into the car, and the maturity of the In-cell technology, more and more large screens corresponding to the car will enter the design planning of the car factory, and the large-size long screen (≥20inch) Due to the strong sense of design and the ability to save system development costs, it will be the mainstream of market shipments starting from 2022. Currently, the mainstream bonding technology for automotive displays is the OCA (Optica lClear Adhesive) full bonding process. Compared with OCR (Optical Clear Resin) has the advantages of simple manufacturing process, low investment cost, fast cycle time and high process yield rate. However, due to the material characteristics of OCA itself, the degass...

Problems solved by technology

Furthermore, in order to be able to meet the use requirements of the curved surface lamination platform, it is necessary to provide pre-lamination auxiliary fixtures at the same time, so as to solve the problem that the curved surface platform cannot be vacuum-adsorbed and laminated.
