Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figures 1 to 7, glass edge strength testing device provided by the embodiment of the utility model includes pressure jig
1 and the pressure sensor that is installed in pressure jig 1.
The pressure sensor is 2kN sensor.2kN sensor can meet common glass cover-plate or glass protection piece
Rim pressure test.
Pressure jig 1 includes the ontology 11 of rectangular cylindrical structures and the triangle column structure for being fixed on 11 lower surface of ontology
Boss 12.
Boss 12 and ontology 11 are arranged based on same reference center face, so that uniform force, but the lateral length of boss 12
It is smaller than the lateral length of ontology 11.In order to easy to process, the transversal cross-section of ontology 11 is rectangle, and boss 12 is triangular prism shaped
Formula.In addition, such as stainless steel and other metal materials integrated molding can be used in ontology 11 and boss 12,
The upper surface 111 of ontology 11 is provided with the blind hole 115 for installing the pressure sensor, the upper surface of ontology 11
In default angle a between 111 and lower surface 114.
Under normal conditions, the upper surface 111 of ontology 11 is parallel to the horizontal plane, therefore works as 111 He of upper surface of ontology 11
When between lower surface 114 in default angle a, the top rib 124 of boss 12 is also between the upper surface 111 of ontology 11 or horizontal plane
Default angle a.
Wherein, the range for presetting angle a is 1 ° to 5 °, preferably 3 °.
When can guarantee to carry out pressure test to glass edge by test device by the way that default angle is arranged, pressure jig
1 is located at the edge of glass 2, raising test accuracy with the contact point of glass 2, that is, the stress point of glass 2.
The longitudinal section of boss 12 is isosceles right triangle, since the boss 12 of triangular prism form can be considered by a triangle
Shape T stretches to be formed, that is to say, that this triangle T is isosceles right triangle.Isosceles on the bottom surface of boss 12, that is, boss 12
The bottom edge side surface 121 of right angled triangle is abutted with the lower surface 114 of ontology 11, two sides of boss 12, also
Side 122 and 123 where being two right-angle sides of isosceles right triangle on boss 12 is symmetrically set about the median plane B of ontology 11
It sets, the apex angle side incline of isosceles right triangle on boss 12, that is, the top rib 124 and glass to be tested of boss 12
EDGE CONTACT.
The longitudinal section of boss 12 be isosceles right triangle, that is, boss 12 two sides 122 and 123 side it is long
It is equal, and angle b is 90 °, the pressure that pressure jig 1 can in this way applied concentrates on the top rib 124 of boss 12, convenient for surveying
Examination.
Preferably, the vertical centerline along two opposite side surfaces 112 and 113 of ontology 11 is respectively arranged with cross section
For the through slot 116 of triangle.
Through slot 116 can improve the stress distribution of pressure jig, and the test data for obtaining pressure sensor is more accurate.
Preferably, the lower edge of former and later two side surfaces 112 and 113 of ontology 11 be equipped with chamfering, and two chamferings respectively with
Side 122 where two right-angle sides of isosceles right triangle is parallel with 123 on boss 12.
When using being integrally formed processing, the lower edge of two to ontology 11 opposite side surfaces 112 and 113 is carried out at chamfering
Reason, in order to easy to process, can make two chamfer planes in the same plane with two sides 122 and 123 respectively.
In the present embodiment, as shown in figure 8, controlling pressure when carrying out strength test to 2 edge of glass by test device
Have a top rib 124 of the boss 12 of 1 lower part, that is, bottom sideline and such as mobile phone glass screen or glass tempering film
Edge line abuts, and is downwardly applied to pressure, is detected with the intensity to glass edge.Since the section of boss 12 is that isosceles are straight
Angle triangle can be such that pressure concentrates on the top rib 124 of boss 12.Again since the upper surface 111 of 1 ontology 11 of pressure jig is under
There is certain angle a between surface 114, and the bottom surface of boss 12 is abutted with the lower surface 114 of ontology 11, that is to say, that the top of boss 12
Rib 124 is also by angle a having the same between the upper surface 111 of ontology 11.So when testing, top rib 124 will be with water
2 surface of the glass a in a certain angle of placing flat, makes EDGE CONTACT of the pressure jig 1 only with glass 2, and the stress point on glass 2 is equal
On its edge line, pressure also be will focus at the stress point on 2 edge line of glass.Pressure sensor can be obtained by deformation
The corresponding test data of multiple glass edge line stress points, and test data is sent to such as host computer.Host computer can basis
Test data effectively analyzes the pressure that glass edge can bear, to provide for glass cover-plate product design with improvement
Data are supported and beneficial reference.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
