Description
Technical field
The utility model relates to a kind of display screen pick-up unit.
Background technology
At present; There is suitable difficulty in the detection of domestic big resolution display screen (display screen of the new especially in recent years high resolving power mobile phone of releasing, MP4, MP5, pixel reaches more than 3,000 ten thousand pixels), relies in the artificial moving process after the enlarged and displayed naked eyes to judge mostly; Automaticity and intelligent degree are very low; Speed is slow, and labor intensive is more, and accuracy of detection and efficient are very low.
The utility model content
The technical matters that the utility model will solve provides a kind of display screen pick-up unit, and it is higher to detect automaticity, saved manpower, and detection speed is fast, and accuracy of detection is high.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of display screen pick-up unit is used to detect display screen, and said display screen pick-up unit comprises base, support, servomotor, control module,
Said base is used for fixing display screen,
Be fixed with X axle motion module on the said support; Be movably equipped with Y axle motion module on the said X axle motion module; Be movably equipped with Z axle motion module on the said Y axle motion module, said Z axle motion module is provided with industrial camera, and said industrial camera is positioned at the top of display screen; The axis normal of the camera lens of said industrial camera is in display screen
The input end of said servomotor is connected in the output terminal of control module, and the output terminal of said servomotor connects and control the action of X axle motion module, Y axle motion module, Z axle motion module respectively,
The input end of said control module is connected to industrial camera and display screen.
Preferably, the pixel of the camera lens of the said industrial camera of the utility model is 1,000 ten thousand.
Preferably, the said control module of the utility model is the PLC controller.
The utility model principle of work is following:
Control module is provided with system default " 0 " on display screen; And begin to be divided into 16 or 32 to display screen from it; Servomotor control X axle motion module and Y axle motion module make the top of the camera motion of industrial camera to the central point of each piece position; After camera lens moves to the subimage position of appointment; Z axle motion module is moved in servomotor control; The continuous photographic images of while industrial camera; And image transferred to control module, and the software in the control module is analyzed the focusing that whether reaches best, and control module transfers to servomotor with signal again and photographed best subimage with the action of control Z axle motion module up to industrial camera; 16 or 32 subimages are recombinated to all subimages after taking and finishing, and are spliced into a complete image, accomplish the collection of the high-definition image of entire display screen; Image analysis software in the control module carry out bad point analysis to the entire display screen high-definition image, draws judged result.
Therefore compared with prior art, the utility model has following beneficial effect:
1, the motion of X axle motion module, Y axle motion module, Z axle motion module is controlled by servomotor, intellectualized operation, and automaticity is higher, and detection speed is very fast, and detection efficiency is higher, has saved manpower;
2, the detection of display screen belongs to micro-imaging; The utility model utilizes the thing square that moves up and down the fine setting industrial camera of Z axle motion module, can reach the optimal imaging effect, and not only detection speed is fast; Also overcome the high difficult problem of motor-driven lens aberration rate; Simplify the difficulty that successive image is handled, improved the accuracy of accuracy of detection and judgement, therefore can detect the display screen of big resolution.
