Description

Scribing wheel

Technical field

The utility model is related to show production technical field more particularly to a kind of scribing wheel.

Background technology

Scribing wheel (Cutting Wheels) is LCD (Liquid Crystal Display, liquid crystal display) cuttings A kind of cutting tool used in technique.Its material is mainly alloy or diamond.The cutting technique of LCD is exactly using tool There is the break bar of certain degree of hardness, under a certain pressure, streak glass surface, to form deep trace together in glass surface, passes through Necessary sliver means so that the deep trace formed in cutting runs through entire glass on the thickness direction of glass, thus will The product size that glass-cutting is needed at us.

Currently, scribing wheel is according to tooth form, we are generally divided into 3 kinds：U-shaped tooth, V-type tooth and without flute profile.Nothing in actual production Flute profile break bar is extremely faint in cutting infiltration, and production stability is poor, does not select and does volume production scribing wheel use.It is generally all selected in volume production U-shaped tooth or V-type tooth are used as scribing wheel.

U-shaped tooth is vertical blade surface, and glass strain fluctuation is big in cutting process, stress concentration, therefore U-shaped serrated knife wheel advantage： Good separating effect；Disadvantage：Chipping (clast) is more, and glass Bending (curvature) is poor.

V-type tooth is basil, and glass strain fluctuation is small in cutting process, and transition is formed between cutting out, and cuts stress not It concentrates, therefore V-type serrated knife wheel disadvantage：Separating effect is poor；Advantage：Clast is less, and glass bend curvature is good.

The break bar of U-shaped tooth and V-type tooth can not take into account the separating effect of glass, and chipping, Bending etc. are cutter Bad problem in skill.

Utility model content

In order to solve the above-mentioned technical problem, the utility model provides a kind of scribing wheel, solves separation when glass-cutting Effect, chipping, Bending etc. are the bad problem in cutting technique.

In order to achieve the above object, the technical solution adopted in the utility model is：A kind of scribing wheel, including sawtooth and tooth Slot, the tooth socket include take the shape of the letter U the first tooth socket of structure and the second tooth socket of V-shaped structure.

Further, first tooth socket and second tooth socket are arranged alternately.

Further, multiple second tooth sockets are provided between two neighboring first tooth socket.

Further, 3-5 second tooth sockets are provided between two neighboring first tooth socket.

Further, the width of the first sawtooth between first tooth socket and second tooth socket is more than two neighboring institute State the width of the second sawtooth between the second tooth socket.

Further, the width of first sawtooth is 3 times of the width of second sawtooth.

Further, the width of second sawtooth is 8-16um.

Further, the width of second tooth socket is 4-5um, and the depth of second tooth socket is 1.5-3um.

Further, the width of first tooth socket is 10-14um, and the depth of first tooth socket is 5-7um.

Further, the scribing wheel angle of the scribing wheel is 105-120 degree.

The utility model has the beneficial effects that：Scribing wheel has the first tooth socket of the structure that takes the shape of the letter U and V-shaped structure simultaneously The second tooth socket, have both the break bar only with the first tooth socket and only with the second tooth socket break bar, with offset individually tool A kind of the shortcomings that tooth socket of standby shape, separating effect when glass-cutting is solved, chipping, Bending etc. are cutting technique In bad problem.

Specific implementation mode

The feature and principle of the utility model are described in detail below in conjunction with attached drawing, illustrated embodiment is only used for explaining The utility model not limits the scope of protection of the utility model with this.

As depicted in figs. 1 and 2, the present embodiment provides a kind of scribing wheel, including sawtooth and tooth socket, the tooth socket includes being in First tooth socket 1 of U-shaped structure and the second tooth socket 2 of V-shaped structure.

Scribing wheel has the first tooth socket 1 of the structure that takes the shape of the letter U and the second tooth socket 2 of V-shaped structure simultaneously, and having both only has The break bar of first tooth socket 1 and the break bar only with the second tooth socket 2 individually have a kind of lacking for tooth socket of shape to offset Point has the first tooth socket of U-shaped structure 1 so that good separating effect when glass-cutting has the second tooth socket of v-shaped structure 2, cuts glass Clast is less when glass, and glass bend curvature is good.Separating effect when glass-cutting is solved simultaneously, and chipping, Bending etc. are to cut Cut the bad problem in technique.

It is bad in cutting technique in order to more effectively solve, in the present embodiment, first tooth socket 1 and second tooth Slot 2 is arranged alternately.

Optionally, multiple second tooth sockets 2 are provided between two neighboring first tooth socket 1.It can also be in phase Multiple first tooth sockets 1 are set between adjacent two second tooth sockets 2, can specifically be set according to actual needs.

In the present embodiment, it is provided with multiple second tooth sockets 2 between two neighboring first tooth socket 1, described The quantity of two tooth sockets 2 can be set according to actual needs, preferred in the present embodiment, and 3-5 is provided between first tooth socket 1 A second tooth socket 2.

In the present embodiment, the quantity of the sawtooth is 200-280.

As shown in Fig. 2, in the present embodiment, 5 second tooth sockets 2 are provided between first tooth socket 1, but not As limit.

In the present embodiment, the sawtooth has the first sawtooth between first tooth socket 1 and second tooth socket 2 4, and the second sawtooth 3 between two neighboring second tooth socket 2, optionally, first tooth socket 1 and second tooth The width of the first sawtooth 4 between slot 2 is more than the width of the second sawtooth 3 between two neighboring second tooth socket 2.

Preferably, the width of first sawtooth 4 is 3 times of the width of second sawtooth 3.

Preferably, the width of second sawtooth 3 is 8-16um.

Preferably, the width of second tooth socket 2 is 4-5um, and the depth of second tooth socket 2 is 1.5-3um.

Preferably, the width of first tooth socket 1 is 10-14um, and the depth of first tooth socket 1 is 5-7um.

Preferably, the scribing wheel angle of the scribing wheel is 105-120 degree.

As shown in figure 3, the scribe-wheel angle is the oblique of the blade face both sides of first sawtooth 4 or second sawtooth 3 Angle a between face 10.

In the present embodiment, the outer diameter L of scribing wheel is 2mm, and internal diameter b is 0.8mm, and thickness c is 0.65mm, but not with this It is limited.

The above is the utility model preferred embodiment, it should be noted that those of ordinary skill in the art are come It says, under the premise of not departing from principle described in the utility model, several improvements and modifications can also be made, these improvements and modifications Also it should be regarded as scope of protection of the utility model.
