Abstract
The utility model discloses a tool for a liquid crystal display. The tool comprises a tool body and a tool bit. One end of the tool body is provided with a tool bit installation part used for installing the tool bit; the tool bit is welded on the tool bit installation part; the end face of the tool bit installation part consists of a first oblique plane and a second oblique plane; the first oblique plane is near the tool bit; the tool bit is made of diamond; and an included angle between the second oblique plane and the center line of the tool body is 60 degrees. As the tool bit is made of the diamond, and the diamond is higher in abrasive resistance, the tool is longer in service life. The tool is longer in service life, and therefore, the frequency of replacing the tool can be reduced, and further, the production efficiency is greatly improved. As the included angle between the second oblique plane and the center line of the tool body is 60 degrees, and when a polarizer is abraded, burrs cannot be easily generated at the edge of the polarizer, and further, the qualification rate of the polarizer is greatly improved.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of LCDs cutter.
Background technology
LCDs is a kind of digital display technique, and it can filter light source by liquid crystal and colour filtering, produces image at screen.Compare with traditional cathode ray tube (CRT) display screen, LCDs have take up room little, low-power consumption, low radiation reduces advantage such as visual fatigue and is widely used.
LCDs is mainly by backlight, glass substrate, colored filter, and upper and lower polaroid constitutes.The size of LCDs is many, in order to save resource, and makes things convenient for the client to use, and the raw material of polaroid all are large stretch of, need large stretch of polaroid be cut into small pieces according to the size of glass substrate usually, and the small pieces polaroid is carried out edging processing.At present, the cutter that is used for the mill polaroid is made by wolfram steel, and the wolfram steel wearability is not high, causes replacing cutter frequency ratio higher, thereby has influenced production efficiency greatly.This cutter comprises blade and cutter head, and blade one end is provided with for the cutter head installation portion that cutter head is installed, and cutter head is welded on the described cutter head installation portion; The end face of cutter head installation portion is made of first inclined-plane and second inclined-plane, and first inclined-plane is near described cutter head.In addition, because the angle between second inclined-plane and the blade center line usually greater than 70 °, when the mill polaroid, causes the polaroid edge to be prone to burr, reduced the qualification rate of polaroid.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of LCDs cutter, and its service life is long, has reduced the number of times of changing cutter, has improved production efficiency, and when the mill polaroid, the polaroid edge is not prone to burr.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of LCDs cutter, described cutter comprises blade and cutter head, and described blade one end is provided with for the cutter head installation portion that described cutter head is installed, and described cutter head is welded on the described cutter head installation portion; The end face of described cutter head installation portion is made of first inclined-plane and second inclined-plane, and described first inclined-plane is near described cutter head; Described cutter head is made by diamond; Angle between described second inclined-plane and the described blade center line is 60 °.
Preferably, the length of the blade of described cutter head is 3.8mm.
By technique scheme, a kind of LCDs cutter that the utility model provides is because described cutter head is made by diamond; Angle between described second inclined-plane and the described blade center line is 60 °, so its service life is long, has reduced the number of times of tool changing tool, improved production efficiency, and when the mill polaroid, the polaroid edge is not prone to burr, has improved the qualification rate of polaroid greatly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the front view that the disclosed a kind of LCDs of the utility model embodiment is used cutter;
Fig. 2 is the vertical view that the disclosed a kind of LCDs of the utility model embodiment is used cutter;
Fig. 3 is the left view that the disclosed a kind of LCDs of the utility model embodiment is used cutter.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Referring to figs. 1 to Fig. 3, a kind of LCDs cutter provided by the utility model, described cutter comprises blade 1 and cutter head 2, and described blade 1 one ends are provided with for the cutter head installation portion (figure does not mark) that described cutter head 2 is installed, and described cutter head 2 is welded on the described cutter head installation portion; The end face of described cutter head installation portion is made of first inclined-plane 11 and second inclined-plane 12, and described first inclined-plane 11 is near described cutter head 2; Described cutter head 2 is made by diamond; Angle a between described second inclined-plane 12 and described blade 1 center line is 60 °.
In addition, the length of the blade of described cutter head 2 is 3.8mm.
A kind of LCDs cutter that the utility model provides, because described cutter head 2 is made by diamond, the diamond wearability is than higher, so its service life is long.The service life of cutter is long, thereby can reduce the frequency of tool changing tool, and then has improved production efficiency greatly.Angle a between described second inclined-plane 12 and described blade 1 center line is 60 °, and when the mill polaroid, the polaroid edge is not prone to burr, and then has improved the qualification rate of polaroid greatly.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
Claims (2)
1. LCDs cutter, described cutter comprises blade and cutter head, and described blade one end is provided with for the cutter head installation portion that described cutter head is installed, and described cutter head is welded on the described cutter head installation portion; The end face of described cutter head installation portion is made of first inclined-plane and second inclined-plane, and described first inclined-plane is characterized in that near described cutter head described cutter head is made by diamond; Angle between described second inclined-plane and the described blade center line is 60 °.
