Mobile phone polaroid laminating machine capable of reliably laminating polaroid

Abstract

The invention relates to a mobile phone polaroid laminating machine capable of reliably laminating a polaroid. A polaroid loading mechanism comprises a loading platform longitudinally lifting mechanism, a loading platform station switching mechanism installed on the loading platform longitudinally lifting mechanism and a polaroid loading platform installed on the loading platform station switching mechanism; the polaroid loading platform comprises a laminated polaroid transferring substrate and a laminated polaroid transferring hinged side panel which is installed on the loading platform station switching mechanism, the laminated polaroid transferring substrate is hinged to the bottom end of the laminated polaroid transferring hinged side panel, the side, opposite to the hinged point, of the laminated polaroid transferring substrate can longitudinally rotate around the laminated polaroid transferring hinged side panel, the laminated polaroid transferring substrate is connected with a laminated polaroid transferring cylinder which drives one side edge of the laminated polaroid transferring substrate to rotate, a polaroid aligning mechanism is installed on the laminated polaroid transferring substrate, a vacuum adsorption plate which can absorb and fix the polaroid is installed at the bottom of the laminated polaroid transferring substrate in an attached mode, and a high-speed camera is arranged on the side edge of a vacuum adsorption seat which is fixed through a glass substrate. The mobile phone polaroid laminating machine capable of reliably laminating the polaroid has the advantages of being reasonable in polaroid laminating action and good in polaroid laminating quality.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display equipment, specifically a mobile phone screen liquid crystal screen polarizer bonding machine. Background technique [0002] The full name of polarizer is polarizer, which is an optical film with the function of generating polarized light composed of multi-layer polymer materials. Its basic structure includes: the middle PVA (polyvinyl alcohol), two layers of TAC ( Cellulose triacetate), PSAfilm (pressure sensitive adhesive), Releasefilm (release film) and Protectivefilm (protective film). The polarizer converts non-polarized natural light into polarized light, and allows the light perpendicular to the electric field to pass through, so that the liquid crystal display panel can display images normally, which is an essential part of liquid crystal display imaging. In the back-end manufacturing process of liquid crystal displays, it is necessary to attach polarizers to glass substrat...

Problems solved by technology

During the pre-bonding process of the polarizer, the polarizer is basically parallel to the glass substrate, and the entire surface is bonded in place in one step. When this method is used for bonding, on the one hand, the pressing force is large, and it is not easy to control, which is easy to cause damage to the glass substrate. The damage will lead to cracking of the glass substrate in severe cases; on the other hand, when the face-to-face bonding is performed, the air between the polarizer and the glass substrate is compressed at the moment of bonding, and the air flow formed at the gap is large, forming a gap of air Air flow can easily lead to material deviation, which affects the bonding quality of the polarizer, and the air removal effect is poor. Polarizer bonding quality; it is inconvenient for operators to observe in real time during the patching process, which brings inconvenience to the patching quality
