Problems solved by technology

[0003] At present, liquid crystal displays with special proportions can be realized by cutting traditional proportioned displays. However, polarizers often need to be torn off manually. This method often causes the polarizer to be broken and the surface is reserved due to uneven force. There are problems such as residual glue, and the operation efficiency is low, which is not conducive to mass production

Embodiment 1

[0025] refer to figure 1 , the polarizer cutting device of this embodiment mainly includes a cutter shaft 11 and two disc-shaped cutter wheels 12, the middle part of the cutter wheel 12 is provided with a shaft hole, and its peripheral surface is a cutting part, and the cutter shaft 11 is penetrated in the shaft hole Afterwards, two cutter wheels 12 are arranged on the cutter shaft 11 in parallel.

[0026] Also, combine figure 2 As shown, the present embodiment also has an auxiliary cutter body 15 for tearing off the cut polarizer 1. The free end of the auxiliary cutter body 15 is a cutter head bent toward the cutter wheel 12, and the free end of the cutter head is wedge-shaped. , can be smoothly inserted between the polarizer 1 and the glass panel 2 .

[0027] First, the polarizer 1 is cut by two coaxial cutter wheels 12, and the cut area is an invalid display area; at the same time, the cut polarizer 1 is removed synchronously by using a cutter device in conjunction with ...

Embodiment 2

[0034] like Figure 5 and Image 6 As shown, different from Embodiment 1, the polarizer cutting device of this embodiment omits the connecting rod 16, and the auxiliary knife body 15 includes connecting arms 151 on both sides and a sheet-shaped knife connected between the two connecting arms 151. The head 152 and the connecting arms 151 on both sides are respectively hinged on the two ends of the cutter shaft 11 . During the rolling process of the cutter wheel 12 , the cutter head 152 is naturally driven by the connecting arm 151 to separate the polarizer 1 and the glass panel 2 , and the structure is simpler.

[0035] The present invention uses the cutter shaft to connect the two cutter wheels together, and the cutting of the polarizer can be completed during the rotation of the cutter wheel, which can quickly and effectively cut and remove the polarizer, improve the yield rate and operation efficiency of the panel, and facilitate follow-up The cutting of the screen body is...

Abstract

The invention discloses a polaroid cutting device, which comprises a cutter shaft and two disc-shaped cutter wheels. Axle holes are formed in the middle parts of the cutter wheels; a cutting part is arranged on the circumference of each cutter wheel; the cutter shaft is arranged in the axle holes in a penetrating way; and the two cutter wheels are arranged in parallel on the cutter shaft. The invention further discloses a polaroid cutting method. According to the polaroid cutting device and the polaroid cutting method provided by the invention, the two cutter wheels are connected together through utilizing the cutter shaft, and a polaroid can be cut during a rotation process of the cutter wheels, so that the polaroid can be quickly and effectively cut and removed, the panel yield and the working efficiency are improved, a screen body can be subsequently cut conveniently, and quantity production can be facilitated.

Description

technical field [0001] The invention relates to the technical field of display panel manufacturing, in particular to a polarizer cutting device and a cutting method. Background technique [0002] In response to the special needs of LCD screens in the current market, for example, limited to various factors such as location, space and decoration, more and more LCD screens with special proportions are gradually appearing on the market, such as banks, shopping malls, subways, etc. All of them are LCD screens with special proportions, which can be used in a wide range of applications. [0003] At present, liquid crystal displays with special proportions can be realized by cutting traditional proportioned displays. However, polarizers often need to be torn off manually. This method often causes the polarizer to be broken and the surface is reserved due to uneven force. There are problems such as residual glue, and the operation efficiency is low, which is not conducive to mass pr...
