Double-feeding vacuum fitting production line and fitting process thereof

Abstract

The invention discloses a double-feeding vacuum fitting production line and a fitting process thereof. The double-feeding vacuum fitting production line comprises a pre-fitting portion and a vacuum fitting portion which are in parallel arrangement, a glass sheet and a TP film are mutually fitted to an integral filmed glass sheet on the pre-fitting portion, and the filmed glass sheet is vacuum fitted on the vacuum fitting portion; the pre-fitting portion comprises a glass sheet feeding mechanism, a fitting manipulator, a TP film feeding platform and a pre-fitting platform; the vacuum fitting portion is provided with at least two vacuum fitting workstations parallelly and comprises a sliding feeding platform, a feeding manipulator, a vacuum fitting mechanism and a discharging manipulator. Multiple vacuum fitting workstations are adopted, so that fitting efficiency is improved effectively, and individual clamping and fixing of a film and the glass sheet are not needed; positioning correction is not needed during vacuum fitting, so that requirements on accuracy during vacuum fitting are lowered and production cost are lowered; vacuum fitting time period is utilized to complete pre-fitting and material conveying, so that time utilization rate is increased, and improving of whole line production capacity is facilitated.

Problems solved by technology

The screen manufacturing process involves a film-attaching process. The film-attaching process realizes the attachment of various sheet-shaped films on the glass sheet. The sheet-shaped films include polarizers, TP films, etc.; Bubbles are easily generated between the sheet and the glass sheet, which affects the quality of the film; in view of this situation, a vacuum film process has appeared in the existing technical means. The air in the airtight environment is pumped out to form a vacuum environment. In the vacuum environment, the film is attached to the glass sheet, which can greatly reduce the occurrence of air bubbles when the film is attached; vacuum lamination mostly adopts the form of a stand-alone machine, and the process of automatic transformation and upgrading of the entire screen production line In the process of realizing the automation of vacuum film lamination, the following key technical problems need to be solved: 1. The traditional stand-alone vacuum lamination can only complete the lamination of a single product at a time, and the lamination efficiency is low, which cannot meet the production capacity requirements of the automated production line; 2. , The existing vacuum bonding method for glass film is to transport the film and glass sheet to the upper laminating chamber and the lower laminating chamber respectively, and the film and the glass sheet are bonded through the laminating upper chamber and the laminating lower chamber. After the film is fixed, the upper and lower chambers are vacuumed, and the upper and lower molds in the upper and lower chambers vacuum-fit the film and the glass sheet in the vacuum environment of the chamber; this kind of structural process requires special clamps in the upper and lower chambers. The mounting structure prevents the diaphragm or glass sheet from falling due to gravity or prevents the position of the diaphragm and glass sheet from shifting before laminating, and when the position of the clamped diaphragm or glass sheet is shifted, the position cannot be adjusted flexibly, which will directly lead to Mounting defective products requires very high positioning and clamping accuracy when feeding film or glass sheets, resulting in equipment manufacturing costs that are much higher than ordinary film laminating equipment, and the market value is not high; 3. The vacuum bonding device of a single machine is fully automated The production line is automatically connected with the front and back processes to shorten the material transfer time and improve the production capacity of the whole line; 4. During the vacuum lamination process, the previous station of the vacuum lamination station is constantly exporting materials, and the latter station is constantly exporting materials. The vacuum lamination station needs incoming materials for processing. Because the vacuum lamination process takes time, material transmission will stop during vacuum lamination, which greatly wastes processing time and is a key factor restricting the increase in production capacity of the entire line. one
