Lining machine for mobile phone polarizer with reliable alignment

Abstract

The invention relates to a lining machine for a mobile phone polarizer with reliable alignment. A polarizer loading mechanism comprises a loading platform longitudinal lifting mechanism, a loading platform station switching mechanism and a polarizer loading platform, wherein the loading platform station switching mechanism is mounted on the loading platform longitudinal lifting mechanism; the polarizer loading platform is mounted on the loading platform station switching mechanism; the polarizer loading platform comprises a lining transferring base plate and a lining transferring hinge lateral plate; the lining transferring hinge lateral plate is mounted on the loading platform station switching mechanism; the lining transferring base plate is hinged with the bottom end of the lining transferring hinge lateral plate; a lateral edge of the lining transferring base plate opposite to a hinge point can be rotated along the longitudinal direction of the lining transferring hinge lateral plate; a lining transferring cylinder which is used for driving the lateral edge of the lining transferring base plate to rotate is connected with the lining transferring base plate; a polarizer aligning mechanism is mounted on the lining transferring base plate; a vacuum absorbing plate which is used for absorbing and fixing a polarizer is lined at the bottom of the lining transferring base plate; a high-speed camera is arranged on the lateral side of a vacuum absorbing base fixed by the lining transferring base plate. The lining machine for the mobile phone polarizer with reliable alignment has the advantages of reasonable lining action and high lining 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...

AI Technical Summary

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
