Abstract
The invention discloses a device for quickly measuring the warping degree of touch screen protective glass. The device comprises a sample conveyor belt, five laser triangle range finders and a fixed base plate. The fixed base plate is fixed over the sample conveyor belt. The fixed base plate is square and is matched with the touch screen protective glass to be measured in shape. The five laser triangle range finders are installed below the fixed base plate, wherein four laser triangle range finders are located at four corners of the fixed base plate, and one laser triangle range finder is located at the center of the fixed base plate. According to the device, the sample conveyor belt quickly conveys samples, and the five laser triangle range finders simultaneously measure distances from four corners of each sample and the center point of the sample to the triangle range finders, the device is capable of quickly detecting the warping degree of the touch screen protective glass and applicable to batch detection on a production line, and moreover the device is simple in structure, convenient to install and use and low in cost.
Description
Technical field
The present invention relates to a kind of measurement mechanism, particularly a kind of touch screen protective glass warpage rapid measurement device.
Background technology
Touch screen protective glass is the ultra-thin glass that meets touch-screen industry requirement of processing through chemical tempering.Along with American apple company releases iPhone mobile phone and iPad panel computer, greatly promoted the commercialization of touch-screen, meanwhile the sector is all the more made clear with strict the specification of touch screen protective glass and test stone.
The technological process of production of touch screen protective glass comprises: sawing sheet, CNC, plain grinding, tempering, silk-screen and baking etc.In these machining processes; due to glass residual stress, be heated inhomogeneous etc.; easily make glass surface Bending Deformation; thereby make finished product touch screen protective glass after fitting with lcd screen; produce larger stress between the two; affect the serviceable life of final display screen, lack at present a kind of device that can fast detecting goes out glass surface flexibility being applicable on streamline.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of warpage degree that can detect fast touch screen protective glass, be applicable to producing the touch screen protective glass warpage rapid measurement device that on line, flowing water detection is applied in batches.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of touch screen protective glass warpage rapid measurement device; comprise sample travelling belt, five laser triangular distance measuring apparatus and fixed base plate; described fixed base plate is fixed on directly over sample travelling belt; fixed base plate is square and mates with touch screen protective glass shape to be measured; described five laser triangular distance measuring apparatus are installed on fixed base plate below; wherein four laser triangular distance measuring apparatus are positioned at four jiaos of fixed base plates, and a laser triangular distance measuring apparatus is positioned at fixed base plate center.
As a further improvement on the present invention, measurement is synchronously opened or closed to described five laser triangular distance measuring apparatus.
The invention has the beneficial effects as follows: the present invention measures four angles of sample and central point apart from the distance of range of triangle instrument by transmit fast sample and five laser triangular distance measuring apparatus in conjunction with travelling belt simultaneously; can detect rapidly the warpage degree of touch screen protective glass; be applicable to producing flowing water detection application in batches on line; and this apparatus structure is simple; easy to install, with low cost.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is that five laser triangular distance measuring apparatus are arranged schematic diagram;
Fig. 3 is tested five sample spot and calculating angularity schematic diagram;
In figure, indicate: 1-sample travelling belt; Five laser triangular distance measuring apparatus of 2-; 3-fixed base plate; 4-touch screen protective glass.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1-2 shows a kind of embodiment of a kind of touch screen protective glass warpage of the present invention rapid measurement device, comprise sample travelling belt 1, five laser triangular distance measuring apparatus 2 and a fixed base plate 3, described fixed base plate 3 is fixed on directly over sample travelling belt 1, fixed base plate 3 be square and with touch screen protective glass 4 form fit to be measured, described five laser triangular distance measuring apparatus 2 are installed on fixed base plate 3 belows, wherein four laser triangular distance measuring apparatus 2 are positioned at 3 four jiaos of fixed base plates, a laser triangular distance measuring apparatus 2 is positioned at fixed base plate 3 centers, measurement is synchronously opened or closed to described five laser triangular distance measuring apparatus 2.
When touch screen protective glass 4 moves to five laser triangular distance measuring apparatus 2 belows; these five laser triangular distance measuring apparatus 2 are opened measurement simultaneously; measurement point comprises the distance of four angles of sample and sample centre distance laser triangulation instrument, finally by these five measurement data, is calculated the warpage degree of sample.
As shown in Figure 3, establishing sample point length direction spacing is L, and cross direction spacing is W; Five points that record are respectively d1, d2, d3, d4 and d5 apart from the distance of laser triangulation instrument.The angularity on the straight line at edge point 1, point 3 and point 5 places is:
Wp1=abs[d3-(d1+d5)/2]/(W
2+L
2)
1/2
Angularity on the straight line at edge point 2, point 3 and point 4 places is:
Wp2=abs[d3-(d2+d4)/2]/(W
2+L
2)
1/2
Can calculate fast the warpage degree of sample thus.
