The position of aforementioned camera is just to LCD to be detected;

Aforementioned signal transmission module is electrically connected with LCD to be detected.

Aforesaid LCD measurement jig, is characterized in that, the below of aforementioned pedestal is provided with slide rail, and pedestal slides on slide rail.

Aforesaid LCD measurement jig, is characterized in that, aforementioned camera bellows is provided with sliding door, and aforementioned sliding door is fixedly connected with pedestal.

Aforesaid LCD measurement jig, is characterized in that, on aforementioned sliding door, is provided with collision bead.

Aforesaid LCD measurement jig, is characterized in that, also comprises: camera adjustable plate, aforementioned camera adjustable plate is L-type, is formed with mounting hole on it, is fixedly connected with respectively by bolt with camera bellows, camera.

Aforesaid LCD measurement jig, is characterized in that, aforementioned microscope carrier is formed with cavity, and aforementioned signal transmission module is arranged in aforementioned cavity.

Aforesaid LCD measurement jig, is characterized in that, also comprises: automatic checkout system, aforementioned automatic checkout system is electrically connected with camera.

Usefulness of the present invention is: simple in structure, easy to operate; Take by camera all processes that LCD shows, can judge very fast the quality of product, testing result is accurate, stable, reliable, has reduced the fraction defective of finished product; Utilize automatic checkout system to detect, detection speed is fast, has greatly improved operating efficiency.

Brief description of the drawings

Fig. 1 is the perspective view of a specific embodiment of LCD measurement jig of the present invention;

Fig. 2 is the top view of the LCD measurement jig in Fig. 1;

Fig. 3 is the right view of the LCD measurement jig in Fig. 2;

The implication of Reference numeral in figure: 1-camera bellows, 2-pedestal, 3-microscope carrier, 4-camera, 5-bolt, 6-LCD to be detected, 7-slide rail, 8-sliding door, 9-collision bead, 10-camera adjustable plate, 11-waist-shaped hole.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.

Referring to figs. 1 through Fig. 3, LCD measurement jig of the present invention comprises: camera bellows 1, the pedestal 2 setting gradually from bottom to up in camera bellows 1 inside, microscope carrier 3, be fixed on the camera 4 at camera bellows 1 top, and signal transmission module (not shown). Wherein, camera bellows 1, for lucifuge, is camera 4 pictures taken, the whether qualified suitable environment that provides of testing product; Microscope carrier 3 is for carrying LCD6 to be detected; Pedestal 2 is arranged at the bottommost of camera bellows 1, and for carrying microscope carrier 3, pedestal 2 is with microscope carrier 3 for being fixedly connected with, and that for example realizes by bolt 5 is fixedly connected with; Signal transmission module is for contacting with LCD6 to be detected by probe and providing test signal for LCD6 to be detected; All processes that camera 4 shows for taking LCD6 to be detected, so the position of camera 4 is just to LCD6 to be detected.

In order conveniently to pick and place LCD6 to be detected, below pedestal 2, be provided with slide rail 7, pedestal 2 slides on slide rail 7, thereby drives microscope carrier 3, LCD6 to be detected to slide.

As the preferred scheme of one, camera bellows 1 is provided with sliding door 8, and sliding door 8 is fixedly connected with pedestal 2. By pushing away, draw sliding door 8, can pick and place easily LCD6 to be detected.

As the preferred scheme of one, on sliding door 8, be provided with collision bead 9. Collision bead 9 can guarantee that sliding door 8 is closed tight, thereby ensures the photophobism of camera bellows 1 inside.

In order to ensure that LCD6 to be detected has optimum position in the visual field of camera 4, be also that camera 4 is adjustable with respect to the position of LCD6 to be detected in order to improve shooting quality simultaneously. As the preferred scheme of one, it can be realized by camera adjustable plate 10. Concrete, camera adjustable plate 10 is L-type plate, is formed with mounting hole 11 on it, is then fixedly connected with camera bellows 1, camera 4 respectively by bolt, thereby realizes the fine adjustment of camera 4 with respect to the position of LCD6 to be detected.

For make camera bellows 1 internal structure succinct, avoid signal transmission module affect the shooting effect of camera 4, as the preferred scheme of one, the microscope carrier 3 in the present invention is formed with cavity, signal transmits module and is arranged in the cavity of microscope carrier 3.

As the preferred scheme of one, LCD measurement jig of the present invention also includes automatic checkout system (scheming not shown). This automatic checkout system is electrically connected with camera 4, receive the picture signal that it transmits, and according to the parameter of prior setting etc. judge content that LCD shows whether correct, whether brightness enough and whether mounting finished product tilts, detection speed is fast, has greatly improved operating efficiency.

With respect to existing LCD measurement jig, measurement jig of the present invention is simple in structure, easy to operate; Take by camera all processes that LCD shows, can judge very fast the quality of product, testing result is accurate, stable, reliable, has reduced the fraction defective of finished product; Utilize automatic checkout system to detect, detection speed is fast, has greatly improved operating efficiency.

It should be noted that, above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
