Description
Technical field
The utility model belongs to the screen testing device field of electronic product, particularly relates to falling sphere measurement jig.
Background technology
The quality direct relation of the screen of electronic product the Consumer's Experience level of electronic product, and therefore the screen of each part electronic product is after production completes, and all needs, through strict test, can put goods on the market after qualified.Wherein falling sphere test needs screen to be positioned on test board and positioning screen center, then steel ball is dropped down onto the center of screen from object height, to detect screen performance.But in actual measurement, need constantly to adjust to prevent it from producing displacement to the position of test board, high degree have impact on the accuracy of test result.
Utility model content
The purpose of this utility model is to provide a kind of falling sphere measurement jig, and structure is simple, can effectively position test board, improves the accuracy of falling sphere test result.
The technical solution adopted in the utility model is as follows:
Falling sphere measurement jig, comprise worktable, worktable is provided with test board, test board hollow and the center being positioned at hollow bulb is provided with infrared light sources, test board both sides are provided with the identical fixture of structure, and fixture comprises the locating piece removably connected with worktable, and the center of locating piece side is provided with internal thread through hole, screw mandrel is connected with internal thread through hole, and screw mandrel contacts towards the end of test board with clamping plate.
Preferably, described clamping plate are installed with fixture block on the plate face of test board.
Preferably, described fixture block is made up of elastomeric material.
Preferably, the plate face of described clamping plate test board is dorsad installed with guidepost, and locating piece is provided with the guide through hole with guidepost clearance fit.
Preferably, the quantity of described guidepost is at least two, and screw mandrel axis is symmetrical relatively.
Preferably, the free end of described screw mandrel is installed with nut.
During work, according to the size of test screen, select the test board of corresponding size, and test board and infrared light sources thereof are placed in the middle of two fixtures, then after determining test board position, manually twist nut, screw mandrel is rotated and promotes clamping plate to move towards test board, when the fixture block on two clamping plate tightly props up two rear flank of test board, namely the fixing of test board position is completed, then screen is placed on test board, and make infrared ray just to the center of screen, screen surrounding adhesive tape is fixed on after on test board, steel ball is fallen impact screen center from eminence, then according to the known method of testing of those skilled in the art, the result of falling sphere test can be obtained.
Compared with prior art, tool has the following advantages the utility model:
1) adopt the center of infrared light sources to screen to calibrate, improve measuring accuracy;
2) adopt screw mandrel to coordinate guidepost to promote clamping plate, fixing test platform speed is fast, and stability is high;
3) clamping plate are by fixture block engaged test platform, and fixture block adopts rubber to make, little to the rigid injury of test board.
Accompanying drawing explanation
Fig. 1 is the structural representation of falling sphere measurement jig in embodiment;
Be labeled as in figure: test board 1, infrared light sources 2, locating piece 3, leading screw 4, nut 5, guidepost 6, clamping plate 7, fixture block 8.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, falling sphere measurement jig, comprise worktable, worktable is provided with test board 1, test board 1 hollow and the center being positioned at hollow bulb is provided with infrared light sources 2, test board 1 both sides are provided with the identical fixture of structure, fixture comprises the locating piece 3 removably connected with worktable, the center of locating piece 3 side is provided with internal thread through hole, screw mandrel 4 is connected with internal thread through hole, screw mandrel 4 contacts towards the end of test board 1 with clamping plate 7, the other end is free end and is provided with nut 5, clamping plate 7 are installed with the fixture block 8 be made up of rubber on the plate face of test board 1, the plate face of clamping plate 7 test board 1 is dorsad installed with two guideposts 6, screw mandrel 4 is symmetrical relatively for two guideposts 6, locating piece 3 is provided with the guide through hole with guidepost 6 clearance fit.
During work, according to the size of test screen, select the test board 1 of corresponding size, and test board 1 and infrared light sources 2 thereof are placed in the middle of two fixtures, then after determining test board position, manually twist nut 5, screw mandrel 4 is rotated and promotes clamping plate 7 to move towards test board 1, when the fixture block 8 on two clamping plate 7 tightly props up two rear flank of test board 1, namely the fixing of test board 1 position is completed, then screen is placed on test board 1, and make infrared ray just to the center of screen, screen surrounding adhesive tape is fixed on after on test board 1, steel ball is fallen impact screen center from eminence, then according to the known method of testing of those skilled in the art, the result of falling sphere test can be obtained.
