Technical field
The utility model relates to the checkout equipment that a kind of LCD makes, the bad point of specifically a kind of LCD automatic detection device.
Background technology
LCD (Liquid Crystal Display, LCD) is present common electronic display unit, go bad a little detection at the production Shi Douhui that dispatches from the factory.In the prior art, this detection method generally is the human eye test, promptly allow LCD show different colors, whether there is bad point and judges the badly size and the color of point by eye-observation then, owing to depend on very much human eye itself, eyes are tired easily after the long-term test, occur the situation that omission survey or false retrieval are surveyed easily, human eye detection can't provide unified criterion in addition, and the promptly identical different people of bad point can obtain different test results.
The utility model content
The technical problems to be solved in the utility model provides a kind of detection bad point of LCD automatic detection device accurately.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The bad point of a kind of LCD automatic detection device, comprise a frame, in frame, be fixed with a work top, the objective table of carrying LCD to be detected is installed on the work top, the objective table top is provided with pick-up lens and three-color light source, and pick-up lens connects with a graphical analysis main frame by data line.
Above-mentioned three-color light source is for can send multiple monochromatic light source, be outside equipped with the can of realizing the interior lights sealing when detecting in frame, and pick-up lens can drive the travel mechanism in length and breadth that the pick-up lens vertical and horizontal move by one and drive the reciprocating mechanism that pick-up lens moves up and down and is installed in the frame.This in length and breadth travel mechanism comprise the longitudinal rail that is fixed in the frame both sides and the cross slide way on the longitudinal rail, longitudinal rail is provided with longitudinal sliding block, the cross slide way two ends are fixed on the longitudinal sliding block, cross slide way is provided with a transverse slider, pick-up lens is fixed on the transverse slider, and longitudinal sliding block, transverse slider are all realized precise displacement by step motor drive.
As optimization to such scheme, described reciprocating mechanism comprises four upright guide rails that vertically are fixed on the work top, be fixed with slide block up and down on the upright guide rail, on the slide block, slide block was realized precise displacement by step motor drive up and down about two longitudinal rails were fixed in.
As the further optimization to such scheme, the guide rail that objective table is arranged by longitudinal direction is movably installed on the work top.
The utility model has replaced traditional human eye test with automatic machinery fully, the reliability, stability and the precision that detect have been improved, can detect the different LCD product of size by adopting varifocal pick-up lens and cooperating three-dimensional moving mechanism to drive three-color light source with pick-up lens, improve the service efficiency of equipment greatly.
