Hot melt film one-time forming laminating process method and device

Abstract

The invention provides a hot melt film one-time forming laminating process method and device. The process method comprises the following steps: 1) fusing a laminating part and a hot melt part on one piece of equipment; the three working procedures of fusion fitting, defoaming and hot melting fitting being one fitting working procedure, so that a working mode of synchronously finishing fitting and hot melting is realized; (2) designing the equipment into a double-wheel structure, the hot melt film being accurately attached to the surface of a product through a pressing roller of the attaching part, completely exhausting gas between attaching faces to enable the attaching faces to be free of bubble residues, and heating the hot melt film and performing edge sealing through a hot melt roller along with pressure. The device adopts a double-wheel structure, deaeration and hot pressing are completed in one step, and the problems that due to product structure factors, a traditional technology and traditional equipment must adopt the technology of firstly attaching, then deaeration and finally hot melting and pressing, the production efficiency is influenced, inconsistency is generated due to long retention time of products, and the product reliability is influenced are solved. The manufacturing time is shortened, and the stability of the product is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a hot-melt film forming and bonding process method and device. Background technique [0002] The new one-time molding lamination technology and equipment replace the traditional hot-melt film attached to the display module, and then degassing and then hot-melt edge sealing. It truly realizes lamination, defoaming, and hot-melt edge sealing in one operation, which avoids the influence of product material properties caused by the long exposure time of the product to the air due to multiple processes, reduces the defects caused by lamination foreign objects, and reduces the scratches on the product surface , Scratches and other defect rates, improve the pass-through rate and production efficiency of the product production process, and make up for the demand for hot-melt film display module products in short supply in the market. [0003] The production technique in ...
