Abstract
The utility model discloses a device for quickly measuring the warping degree of touch screen protection glass, which comprises a sample conveying belt, five laser triangular distance measuring instruments and a fixed bottom plate, wherein the fixed bottom plate is fixed right above the sample conveying belt, the fixed bottom plate is square and matched with touch screen protection glass to be measured in shape, the five laser triangular distance measuring instruments are installed below the fixed bottom plate, four of the laser triangular distance measuring instruments are located at four corners of the fixed bottom plate, one of the laser triangular distance measuring instruments is located at the center of the fixed bottom plate, the distance between each of the four corners of the sample and the triangular distance measuring instrument and the distance between the center of the sample and the triangular distance measuring instrument are measured simultaneously through combining the conveying belt used for conveying the sample quickly and the five laser triangular distance measuring instruments, thereby being capable of quickly detecting the warping degree of the touch screen protection glass, and being applicable to batched detection on a production line. The device disclosed by the utility model is simple in structure, convenient to install and use, and low in cost.
Description
Technical field
The utility model 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 through chemical tempering processing.Along with American apple company releases iPhone mobile phone and iPad panel computer, greatly promote the commercialization of touch-screen, meanwhile the specification of the sector to touch screen protective glass and test stone is all the more made clear and strictly.
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 utility model provides a kind of warpage degree that can detect fast touch screen protective glass, is applicable to producing the touch screen protective glass warpage rapid measurement device that on line, flowing water detection is applied in batches.
The utility model 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 further improvement of the utility model, measurement is synchronously opened or closed to described five laser triangular distance measuring apparatus.
The beneficial effects of the utility model are: the utility model is measured four angles of sample and the central point distance apart from 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 utility model;
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 understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
Fig. 1-2 shows a kind of embodiment of a kind of touch screen protective glass warpage of the utility model 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.
In the time that 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, is finally calculated the warpage degree of sample by these five measurement data.
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 apart from the distance of laser triangulation instrument, d2, d3, d4 and d5.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 thus the warpage degree of sample.
