Abstract
A position regulating device used for testing the COG compression joint performance in a LCD industrial unit comprises a front positioning structure fixed at the front end of a module to be tested, a left clamping structure which is arranged in a groove and can slide along the groove, a spring which is also arranged in the groove and is adjacent to the left clamping structure, a right clamping structure which is arranged in another groove, and a regulating lever which is also arranged in another groove and is adjacent to the right clamping structure; wherein, the left clamping structure is arranged at the left side of the module to be tested, wherein, the right clamping structure is adjacent to the right side of the module to be tested. By regulating the position of the groove which a LCD is arranged in, the utility model results in that a LCD glass electrode is justified with a FPC electrode so as to be convenient for carrying out the inspection of the product quality and judgment of the fault of the module before the FOG process is applied to products.
Description
Technical field
The utility model relates to a kind of performance test apparatus of LCD, specifically a kind of apparatus for adjusting position that is used to test in COG (chip on glass, the technology that IC integrated circuit and LCDs LCD directly are connected by anisotropic conductive film ACF) the back module performance frock.
Background technology
At present in TFT-LCD LCD manufacturing, after finishing, the COG crimping can't directly test its performance with frock, this is because LCDs LCD input end position goes between generally all at 0.1mm, electrode gap is at 0.18mm, use thimble can't satisfy the test of this clearance electrode, more because electrode is too thin, secret emissary's naked eyes can't directly carry out bit manipulation, this kind test almost can't realize.Existing way is must be by FOG (film on glass, the technology that flexible circuit board FPC is connected with LCDs by ACF) just can test after the hot pressing, finding fault and judging that display module exists temporal hysteresis quality when bad that the quality of FPC itself is bad can't to be displayed like this.Especially when product is keeped in repair, can not test having only the product behind the COG, to judge this liquid crystal display whether the value of maintenance is arranged, and whether FPC is certified products.
Summary of the invention
The purpose of this utility model provides a kind of apparatus for adjusting position that is used for testing the LCD frock of COG crimping performance, adjusting includes the groove location of LCD, the LCD glass electrode is easily alignd, so that before FOG hot pressing, the product behind the COG is carried out performance test with the FPC electrode.
The purpose of this utility model is achieved through the following technical solutions:
A kind of apparatus for adjusting position that is used for testing the LCD frock of COG crimping performance, it comprises:
One is fixed in the prelocalization structure of module front end to be measured;
One left screens structure and spring that is arranged in groove equally and is adjacent to this left side screens structure that is arranged in groove and slides along this groove wherein should left side screens structure be arranged in the left side of module to be measured;
A right screens structure and an adjuster bar that is arranged in this another groove equally and links to each other with another spring that this right side screens structure is provided with that is fixed in another groove wherein should right side screens structure be adjacent to the right side of this module to be measured.
Wherein, this device also includes a STEP key and a REST key.
Positive progressive effect of the present utility model is:
Adjusting includes the groove location of LCD, and the LCD glass electrode is easily alignd with the FPC electrode, so that light display module before product carries out FOG technology, module is carried out the check and the failure judgment of its product quality.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
The utility model is a benchmark with display module horizontal positioned and the direction of facing its display image.
Shown in Fig. 1-Fig. 2 b, a kind of apparatus for adjusting position that is used for testing the LCD frock of COG crimping performance, it comprises:
One is fixed in the prelocalization structure 1 of module 6 front ends to be measured, and this prelocalization structure 1 plays the effect of restriction module to be measured 6 positions, makes module 6 to be measured just in time be in FPC flexible circuit board below;
One left screens structure 3 and spring 4 that is arranged in groove 2 equally and is adjacent to this left side screens structure 3 that is arranged in groove 2 and can slides therein.By the elastic shrinkage and the elongation of this spring 4, this left side screens structure 4 can be slided in groove 2, under the acting in conjunction of right screens structure 5 display module 6 to be measured is fixed;
A right screens structure 5 and an adjuster bar 8 that is positioned at this groove 7 equally that is fixed in the groove 7.This right side screens structure 5 is built-in with a spring 11, and this spring 11 links to each other with this adjuster bar 8, and this spring 11 uses a suitable strength to keep certain elasticity strength right screens structure 5.Rotate this adjuster bar 8 and promote right screens structure and move, and the adjusting by spring 11 and then drive left screens structure and move, realized to the moving of module 6 horizontal directions to be measured, to carry out the contraposition of FPC flexible circuit plate electrode and LCD electrode;
A REST key 9 and a SETP key 10, wherein STEP key 10 is used for changing between each testing procedure, and REST key 9 is used for the test result zero clearing, again module is tested.
This device also is connected with a camera.
When putting into module 6 to be measured and detect, promote left screens structure 3 with the hand direction of turning left, it slides along groove 2, spring 4 is compressed, make that the gap is greater than module size between left screens structure 3 and the right screens structure 5, module 6 to be measured is put between the above-mentioned space, and be pushed to prelocalization structure 1 place forward, module to be measured 6 approximate location at this moment are under FPC flexible circuit plate electrode.Loosen left screens structure 3, this module 6 to be measured is when being connected on the right screens structure 5, and left screens structure 3 is rebounded under the effect of spring 4 elastic force, and under the clamping of left screens structure 3 and right screens structure 5, module 6 to be measured is fixedly positioning.At this moment, utilize another regulating device that the LCD electrode on the module 6 to be measured is contacted with FPC flexible circuit plate electrode, then rotate this adjuster bar 8, it promotes right screens structure 5, make module 6 to be measured under the acting in conjunction of adjuster bar 8, spring 4 and spring 11 and by move left and right, adjust the left and right directions of module 6 to be measured when aligning and coinciding and regulate with the FPC flexible PCB.Observe the LCD electrode and whether FPC flexible circuit plate electrode overlaps by a camera (figure do not show), after the coincidence, press the pressing plate on this another regulating device, the LCD electrode is closely contacted with FPC flexible circuit plate electrode.Open power switch on the frock, press REST key 9 and begin module 6 to be measured is tested, progressively press SETP key 10 again, between different detection pictures, regulate.
