Problems solved by technology

[0003] However, the following problems exist in the cutting of existing polarizers. a. Most of the existing polarizers are cut by manual cutting machine polarizers. When cutting, the polarizers need to be manually placed on the Cutting the polarizer on a manual cutting machine has low production efficiency and uneven cutting; b. After the cutting equipment used in the traditional polarizer cutting process cuts the polarizer, the polarizer will appear white There will be knife marks, delamination and sawtooth on the edge of the polarizer, or the edge of the polarizer, resulting in waste of materials, high defective rate, low product quality and low effective utilization rate

Embodiment Construction

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0033] Such as Figure 1 to Figure 8 As shown, a liquid crystal polarizer manufacturing, processing and cutting process is characterized in that it mainly includes the following steps:

[0034] Step 1, cutting process, place the polarizer that needs to be cut on the polarizer cutting device to cut the polarizer, cut the polarizer to the required size, and obtain the cut polarizer;

[0035] Step 2, edging operation, using an edging machine to perform an edging operation on the cut polarizer obtained in step 1, and cleaning the edging place to obtain a polarizer that has been edged;

[0036] Step 3, detection processing, put the edged polarizers obtained in step 2 into the detection machine for polarizer axial detection and judgment, classify the det...

Abstract

The invention relates to a liquid crystal polarizer manufacturing, processing and cutting process, which mainly includes the following steps: cutting, edging, testing, packaging and other processes. The polarizer cutting equipment used includes a bottom plate and a cutting device. , a positioning device and a cutting device, the present invention can solve the following difficult problems that exist when cutting the existing polarizer, a, most of the existing polarizer cutting is to use a manual cutting machine to cut the polarizer, and when cutting It is necessary to manually place the polarizer on the manual cutting machine to cut the polarizer many times, the production efficiency is low, and the cutting is uneven; b. The cutting equipment used in the traditional polarizer cutting process After cutting, the polarizer will have white edges, or the edges of the polarizer will have knife marks, delamination, and sawtooth, which will result in waste of materials, high defective rate, low product quality and low effective utilization rate.

Description

technical field [0001] The invention relates to the technical field of production of liquid crystal polarizers, in particular to a process for manufacturing, processing and cutting liquid crystal polarizers. Background technique [0002] The full name of liquid crystal polarizer is polarizer, which is widely used in the field of optical instruments such as displays, and is an indispensable part of liquid crystal imaging. vinyl alcohol (PVA). In terms of manufacturing process, the front-end manufacturing process of polarizer is polyvinyl alcohol (PVA) film roll, which is dyed with iodine and then uniaxially stretched to form polarizers and then laminated, and a layer of triacetate cellulose is added on the top and bottom Ester (TAC) film, and a surface protection film is applied outside the upper TAC film, and a release film or a reflective film is attached to the lower TAC film with an optical adhesive, and then the surface protection film is pasted, and finally entered Su...
