Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1-Figure 3, it is the embodiment one of wheel structure of the present invention.
Wheel structure in the present embodiment, in AMOLED procedure for producing, to carry out edging to the glass after cutting and fall
Angle, including：Abrasive wheel body 1；Be opened on 1 circumference of abrasive wheel body according to certain regularly arranged multiple tooth sockets 2, tooth socket 2 is
Circular ring structure, the inner surface that tooth socket 2 is ground glass include：The section of supporting surface 21, supporting surface 21 is set as straight line 210,
It is connected to the transition face 22 of 21 opposite sides of supporting surface, the section of transition face 22 is the first camber line 220；It is connected to 22 phase of transition face
To the grinding surface 23 on both sides, the section of grinding surface 23 is the second camber line 230, wherein：The first curvature radius of first camber line 220
Less than the second curvature radius of the second camber line 230, to keep the curved surface being connected between grinding surface 23 by supporting surface 21 smoothed
It crosses, and reduces stock removal of 2 inner surface of tooth socket to glass.
When it is implemented, supporting surface 21 is located at the bottom of tooth socket 2, the centerline axis parallel of straight line 210 and abrasive wheel body 1.
Wherein：The section of supporting surface 21 is set as to the effect of straight line is：During grinding is embodied, the position residing for supporting surface 21
It is set to the supporting surface of grinding, the length of straight line 210 determines the size to glass support position.In the present embodiment, 2 supporting surface of tooth socket
The length of 21 section straight line 210 is less than the length of the section line of the tradition angles C tooth socket emery wheel supporting surface, but is more than the tradition angles R tooth
The length of the section line of slot emery wheel supporting surface.In this way, the further length of adjustment 22 the first camber line of section 220 of transition face, and mill
The length of 23 the second camber line of section 230 of bevel, when making to be ground glass, the mill only at 230 position of the second camber line of section
Bevel 23 is ground with glass, is promoted the edging stock-removing efficiency of glass, is promoted the quality of edging.
Further, transition face 22 is upper and lower two parts curved-surface structure, is connected to the opposite sides of supporting surface 21, this
Two parts up and down of transition face 22 are set as symmetrical in embodiment, and the section of transition face 22 is the first camber line that curvature is 0.1mm
220, the effect by the way that the first curvature of 22 first camber line 220 of transition face to be set as to 0.1mm is to realize the transition work(of the curved surface
Can, corner angle are not generated when the section straight line 210 of supporting surface 21 being made to be connect with 23 the second camber line of section 230 of grinding surface, promote glass
Edging stock-removing efficiency, promote the quality of edging.
Further, grinding surface 23 is upper and lower two parts curved-surface structure, is connected to the opposite sides of transition face 22, this
Two parts up and down of grinding surface 23 are set as symmetrical in embodiment, and the section of grinding surface 23 is radius of curvature is 1.19 mm second
Camber line 230, the effect by the way that the second curvature radius of 23 second camber line 230 of grinding surface to be set as to 1.19 mm are：Make supporting surface
21 section straight line 210 does not generate corner angle when being connect with 23 the second camber line of section 230 of grinding surface, when making to be ground glass,
Grinding surface 23 only at 230 position of the second camber line of section is ground with glass, promotes the edging stock-removing efficiency of glass, is promoted
The quality of edging.
Incorporated by reference to referring to Fig. 3, the section of the section line and the angles R tooth socket emery wheel of the traditional angles C tooth socket emery wheel is illustrated in Fig. 3
Line, the first curvature radius of the first camber line 220 is set as being less than the second camber line by wheel structure in detailed description below the present embodiment
Advantage of 230 second curvature radius compared to the traditional angles C tooth socket emery wheel and the tradition angles R tooth socket emery wheel.
In diagram, the frame line T on right side is the datum line of glass edge to be ground, the section line of the traditional angles C tooth socket emery wheel
For E, the section line of the traditional angles R tooth socket emery wheel is F, and the section line of 2 inner surface of tooth socket is G in the present embodiment, by glass to be ground
The datum line T at edge is respectively E with the section line of the traditional angles C tooth socket emery wheel, the section line of the tradition angles R tooth socket emery wheel is F, and
In the present embodiment the section line of 2 inner surface of tooth socket be area folded by G size can be seen that section line be G with folded by datum line T
Area<Area folded by section line E and datum line T<Area folded by section line F and datum line T.
It follows that stock removal of the tradition angles the R tooth socket inner surface to glass>Mill of the traditional angles C tooth socket inner surface to glass
The amount of cutting>2 inner surface of tooth socket is to the stock removal of glass in the present embodiment, and the bigger emery wheel that represents of stock removal is more easy to wear, glass
Stress loss is more, and collision more easy tos produce fragmentation.Meanwhile by the length of section line from the point of view of, the traditional angles C tooth socket inner surface section
The length of line<The length of 2 inner surface section line of tooth socket in the present embodiment<The length of the traditional angles R tooth socket inner surface section line.And it grows
Degree is longer, and grinding area is bigger, and the micro-crack probability of generation is higher.
That is, on AMOLED processing procedures, the glass after having been ground using novel emery wheel in the present embodiment is had more moderate
Support level, less micro-crack, and do not have corner angle, follow-up process as be deposited and encapsulation during, be not likely to produce fragmentation
And glass chip, percent of pass and yield for overall process have good promotion.In cost, using new in the present embodiment
The stock removal of type emery wheel is minimum, and the degree of wear of emery wheel is lower, and the quantity of same its ground glass of emery wheel is more, then we grind
The replacement cycle of wheel is longer, and conversion is minimum to cost when monolithic glass.
In the present embodiment in the other embodiment of wheel structure, can be arranged it is multiple there is above structure, but size is not
With multiple tooth sockets on same abrasive wheel body 1, meanwhile, it is multiple tooth sockets are parallel and set.In this way, emery wheel is enable to be ground out difference
The glass arris of chamfering angle size, increases the adaptive faculty of emery wheel.
Implement wheel structure provided by the present invention, has the advantages that：Tooth socket is circular ring structure, and tooth socket is to glass
The inner surface being ground includes：The section of supporting surface, supporting surface is set as straight line, is connected to the transition of supporting surface opposite sides
The section in face, transition face is the first camber line；The section of the grinding surface being connected in transition face opposite sides, grinding surface is the second arc
Line, wherein：The first curvature radius of first camber line is less than the second curvature radius of the second camber line, to make to be connected to by supporting surface
Curved surface between grinding surface seamlessly transits, and reduces tooth socket inner surface to the stock removal of glass, can reduce hallrcuts and corner angle,
Promote the product yield in overall process；The stock removal to glass can be reduced, reduce the degree of wear of emery wheel, extend and replace week
Phase reduces cost.
