Panel fitting device and processing method thereof

Abstract

The invention discloses a panel fitting device and a processing method of the panel fitting device, and belongs to the technical field of panel display. The panel fitting device at least comprises a base, a first adsorption plate and a support mechanism, wherein a cover plate is placed on the base, the first adsorption plate adsorbs a flexible substrate and drives the flexible substrate to be attached with the cover plate, the support mechanism is arranged on the base and is at least provided with a support air bag and a pressure control device, the support air bag is at least provided with a contact surface, a first film layer is contacted with the contact surface, the pressure control device is provided with at least one air vent, the support air bag is connected with the air vent, and the invention further comprises the processing method of the panel fitting device. The support mechanism provided with the support air bag and the pressure control device is arranged, so that the flexible substrate is stably fitted in the attaching process, and no bubble is produced.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a panel bonding device and a processing method thereof. Background technique [0002] OCA (Optical Clear Adhesive) is an important bonding material for touch screen terminals. It is made of optical acrylic adhesive without substrate, and then laminated a layer of release protective film on the upper and lower bottom layers. It is a double-sided laminating tape without matrix material. It has a high transparency with a light transmittance of more than 99%, and it will not damage the appearance when used in strong light, high temperature and high humidity environments. It can be used for lamination of cover glass and touch panel, lamination of touch panel and display panel, lamination of color filter substrate and display panel, lamination of polarizer and touch panel, etc. Existing optical adhesive bonding is divided into soft-to-soft bonding, hard-to-hard bonding, a...

AI Technical Summary

Problems solved by technology

When the attachment starts, the rubber roller rotates between the adsorption plate and the soft touch panel, so that the soft touch panel is gradually separated from the upper adsorption plate. Due to the release of the adsorption vacuum and insufficient grip, the soft touch panel It falls to the cover plate in advance, so it is easy to generate air bubbles during the bonding process, and it is easy to deviate from the preset bonding position, resulting in misaligned bonding

Due to the heavy weight of soft touch panels, this phenomenon often occurs in the production process of soft-to-hard panel lamination, which affects the yield of panel production
