Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment and conjunction with figs., the present invention is described in more detail.
Fig. 1 is test fixture one-piece construction figure of the present utility model; As shown in the figure, this test fixture is made up of base, column, mobile phone anchor clamps 11 and microphone holder 14, wherein, column is installed on the horizontal concrete chute of base by cogwheel gearing, position by lateral adjustments handwheel 15 lateral adjustments columns, cogwheel gearing is set between mobile phone anchor clamps 11 and the column equally, vertically regulate the position of mobile phone anchor clamps 11 by vertical control hand wheel 1, microphone holder 14 is fixed on the base, microphone holder 14 is provided with height setting nut nail 13, can need with adaptive testing by manual adjustments microphone height.
Digital display meter 2 is installed on column, and digital display meter 2 detects the adjustment state of vertical control hand wheel 1 and lateral adjustments handwheel 15, is used for showing the relative position of each measurement point distance center point of LCD.
As shown in Figure 2, mobile phone anchor clamps 11 are divided into two separating parts up and down, by anchor clamps handwheel 8, and the folding scope of alignment jig 11; Two parts up and down of mobile phone anchor clamps 11 have horizontal concrete chute 16, sectional fixture claw 10 in the chute 16, anchor clamps claw 10 can slide at the slideway of chute 16, and by distance between the setting nut 9 alignment jig claws 10, and stationary fixture claw 10, by the adjustment of anchor clamps handwheel 8 and anchor clamps claw 10, tested mobile phone is fixed and can be adapted to the tested mobile phone of different length and width specifications.
Shown in Fig. 2 and 3, microphone holder 14 comprises a fixed bar 18 and the erecting frame 17 that can slide longitudinally on fixed bar, by the height of height setting nut nail 13 adjusting erecting frames 17, further regulate the height that is installed in the microphone 6 on the erecting frame 17; Set gradually the mounting hole of laser lamp 3, range finding backing pin 5, microphone 6, range finding backing pin 5 on the erecting frame 17, respectively fixing the said equipment parts; Laser lamp 3 is used for determining tested mobile phone LED screen coordinate position at zero point; Microphone 6 is sleeved in the chuck 4, is installed in the corresponding mounting hole, and by holding out against fixedly microphone 6 of screw 7, chuck 4 prevents that the anchor clamps tension from causing damage to microphone 6 when fixing microphone 6; Range finding backing pin 5 is used for the adjusting of microphone 6 and lcd screen relative position, and according to test request, this fixed distance is 5mm.
Concrete operations are as follows during test:
1, checks that each several part equipment connects, and normally moves to guarantee system;
2, mobile phone is fixed on the anchor clamps, alignment jig, personnel manually finish the selected of null position; Unclamping setting nut 9 can move left and right anchor clamps claw 10, and turn anchor clamps handwheel 8 can alignment jig folding scope, adapts to the mobile phone 12 of different size.
Microphone holder 14 is used for fixing microphone 6, and the relative position between location microphone 6 end faces and lcd screen is simultaneously accurately adjusted microphone 6 by holding out against screw 7 and height setting nut nail 13 before and after can be up and down.Push and rotate two the range finding backing pins 5, backing pin 5 is stretched out with lcd screen to be contacted, the distance of determining end face distance microphone 6 end faces that two range finding backing pins 5 form with the measurement annex is 5mm, rotates two range finding backing pins 5 and makes it withdrawal, guarantees the end face and the lcd screen gathering 5mm of microphone 6.
Use laser lamp 3 to be used for determining the coordinate at zero point.Regulate coordinate position, the luminous point of laser lamp 3 is overlapped with lcd screen zero point, laterally vernier caliper zero clearing, regulate lateral coordinates, make mobile phone be moved to the left 27mm, the axle center that is microphone 6 overlaps (optical axis of laser lamp 3 and microphone centre distance 27mm) with the LCD zero mark, again horizontal and vertical vernier caliper zero clearing.The vertical position that control hand wheel 1 and lateral adjustments handwheel 15 can cell phones 12, with convenient each measurement point that switches on the lcd screen, at this moment, the X that shows on the digital display meter 2, a logarithm value of Y direction is used for showing the position coordinates of each measurement point distance center point of LCD.After mobile phone location is fixing, clamp can be begun test.
3, open testing software, choose the test setting file, then beginning lamp on the software interface is lighted, press the operation button and promptly finish the test of a point, and the like finish all test points.Note when testing every mobile phone and must survey zero point earlier.
4, all test point tests are finished, data are deposited in the fixing file of PC, open the testing software data processing section, require the input line number according to the interface, columns, zero point, place line number and testing mobile phone quantity were chosen report template and location paths that test data is deposited, and clicked the operation button and can generate test report automatically.
LCD of mobile phone panel noise test fixture of the present utility model is applicable to the mobile phone of most of specifications, but the wide mobile phone of clamping 40-100mm, and clamping the mobile phone back side, back does not have and blocks, and has avoided outside disturbing factor, has improved measuring reliability; Use laser lamp to determine zero point, use vernier caliper to adjust test point, accurately quick; Mike's stationary installation is used for measuring the distance (5mm) between Mike's end face and LCD surface, remains unchanged to guarantee relative distance, has improved the accuracy of test greatly, makes test more efficiently convenient.
