Fig. 2 is the structural representation of another angle of the utility model Automated visual inspection system for high;
Fig. 3 is the structural representation of mechanism for testing in the utility model.
Embodiment:
Below in conjunction with specific embodiments and the drawings the utility model is further specified.
As shown in Figure 1, 2, the vision detection system of large scale flat-faced screen described in the utility model comprises for the travelling belt 1 of placing and transmit display screen, also comprises screen position straightening mechanism 2 and visual test station 3.
Particularly, travelling belt 1 is arranged on display screen aligning gear 2 and 3 the place aheads, visual test station, connects two stations and plays the effect of placing and transmitting display screen.
The correction box 22 that described screen position straightening mechanism 2 has the first cylinder 21 and driven by the first cylinder 21 is equipped with four block inductors 23 on the described correction box 22; Correction box 22 be vertical setting namely with travelling belt 1 plumbness; Its four block inductors 23 lay respectively at the Si Jiaochu of correction box 22, and rectangular distribution, the installation of block inductor 23 should guarantee that it can touch the housing of display screen simultaneously.
Described visual test station 3 has a worktable 31 and the mechanism for testing 32 that is arranged on the worktable 31, and on worktable 31, the outside of mechanism for testing 32 is provided with a removable darkroom cover 33, removable darkroom cover 33 has four shading surfaces, respectively upper surface, two sides and rear surface, lower surface is to be slidingly mounted on the worktable 31, and the front surface opening is so that be with detection display screen cover to enter wherein to test.Removable darkroom cover 33 can make up a testing environment that light luminance is unified, makes detection can not be subject to the impact of external environment condition brightness, makes testing result more accurate.
As shown in Figure 3, described mechanism for testing 32 comprises the sliding rail frame 321 that is arranged on the worktable 31 and is installed in x on the sliding rail frame 321 to slide unit 322, and x is driven by the first servomotor 323 that is arranged on sliding rail frame 321 the place aheads to slide unit 322; Described x is equipped with y to slide 324 on slide unit 322, y is equipped with two groups of z to support 325 on slide 324, and z drives to the second servomotor 326 on the slide 324 by being arranged on y to support 325; Each z is separately installed with testing lens 327 on support 325.
Described two groups of z drive by the second servomotor 326 by being arranged on the forward lead screw of y in interior to slide 324 to support 325, and every group of z is respectively two testing lens 327 setting up and down on support 325, i.e. four testing lens 327 rectangular distributions.Two groups of z are opposite to the direction of motion of support 325, thereby regulate two groups of z to support 326 be on it y between testing lens 327 to distance, adding testing lens 327 can regulate by the position of mounting hole etc. to the distance on the support 325 at z, therefore the size of four testing lens 327 formed test rectangle scopes can be regulated as required, thereby the display screen that satisfies the different area size is tested.
The utility model aligning gear carries out timing, display screen 4 is artificial loading when material loading, therefore can not guarantee that the angle of display screen is plumbness just, tilt up or down often, even small angle of inclination also is very large on result's impact of test, therefore, need to utilize the 2 pairs of display screens of screen position straightening mechanism in the utility model to adjust correction.Control that the first cylinder 21 is pushed ahead correction box 22 and fixed live, the front end face of 4 block inductors 23 on the correction box 22 is in the vertical plane at this moment, when the workman places display screen on the travelling belt 1, cooperate screen position straightening mechanism 2, manually adjust position and the angle of display screen, front and 4 block inductors 23 of display screen are touched simultaneously, block inductor 23 sends corresponding induced signal, the expression display screen is in plumbness, correction is finished, and can enter visual test station 3 and test.
When display screen 4 to be detected is positioned at the place ahead at visual test station, removable darkroom cover 33 on the worktable 31 moves forward under the driving of the second cylinder 331, cover display screen to be detected fully, make display screen 4 be arranged in a relatively dark environment, and then the mechanism for testing of controlling in it detect.Mechanism for testing is mainly by the xy electric platforms, and the camera lens of controlling on it by servomotor carries out image acquisition, is then processed by the vision processing system of testing station main frame and merges, thereby obtain test result.After test was finished, removable darkroom cover 33 was removed automatically, and the display screen that travelling belt 1 will detect again is delivered to unloading station and gets final product.
In sum, the utility model large scale flat-faced screen vision detection system, can utilize the screen position straightening mechanism to make the angle of display screen be in plumbness, make it the test position that reaches unified, then automatically enter test station by travelling belt, automatically finish visual test in the darkroom environment that removable darkroom cover 33 forms, automatically be sent at last unloading station, the manual cleaning gets final product.Therefore, adopt the utility model vision detection system that the large scale flat-faced screen is carried out vision-based detection, can guarantee that the display screen angle orientation is accurate, locating speed is fast, is conducive to improve accuracy rate and the testing efficiency of test; And removable darkroom cover can make up a testing environment that light luminance is unified, makes detection can not be subject to the impact of external environment condition brightness, makes testing result more accurate.
