Abstract
Disclosed is a clamping board adjusting device used in the technological equipments that test the module performance after COG. The device comprises a clamping board, a connecting plate connected with the clamping board through a guide shaft, a telescopic handle which is connected with the connecting plate through a connecting rod and drives the connecting plate to stretch inwards and outwards by the connecting rod, and a cam arranged on the clamping board. The utility model can adjust the position of the clamping board, and make the FPC flexible circuit board electrode and the LCD glass electrode effectively contacted through extrusion of the clamping board, in order to inspect the product quality and judge the failure of the modules before FOG of products.
Description
Technical field
The utility model relates to the performance test apparatus in a kind of LCD manufacture process, pressing plate regulating device in the frock of specifically a kind of test COG (chip on glass, the technology that IC integrated circuit and LCDs LCD directly are connected by ACF) back module performance.
Background technology
At present in TFT-LCDs 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 0.1 millimeter, electrode gap is at 0.18 millimeter, use thimble can't satisfy the test of this clearance electrode, more, naked eyes can't directly be carried out bit manipulation, make this kind test almost can't realize because electrode is too thin, close.Existing way is must be by FOG (film on glass, the technology that flexible circuit board FPC flexible PCB is connected with LCDs by ACF) just can test after the hot pressing, finding fault and judging that product exists temporal hysteresis quality when bad that the quality of flexible circuit board FPC flexible PCB itself is bad can't to be displayed like this.Especially when product is keeped in repair, can't directly test, whether the value of maintenance be arranged, and whether the FPC flexible PCB is certified products to judge this liquid crystal display to the product after the COG crimping.
Summary of the invention
The purpose of this utility model provides the pressing plate regulating device in the frock of module performance behind a kind of COG of test, can regulate the position of pressing plate, and FPC flexible circuit plate electrode is effectively contacted with LCDs LCD glass electrode, so that before FOG hot pressing, the product after the COG technology is carried out performance test.
The purpose of this utility model is achieved through the following technical solutions:
Pressing plate regulating device in a kind of frock of testing module performance behind the COG, it comprises: the web joint that a pressing plate, is connected with this pressing plate by a guide shaft, connects and drives flexible Telescopic handle and inside and outside this web joint by a connecting link and is arranged at cam on this pressing plate.
Wherein, this pressing plate is near the FPC flexible PCB that posts module to be measured on the lower surface of web joint one end with double faced adhesive tape.
Wherein, this web joint is arranged with an elastic caoutchouc.
Wherein, this cam is provided with one handle.
Wherein, this device also includes a camera.
Positive progressive effect of the present utility model is: the position that can regulate pressing plate, and FPC flexible circuit plate electrode is effectively contacted with LCDs LCD glass electrode, so that 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 Fig. 1-Fig. 3, to describe the technical solution of the utility model in detail.
Pressing plate regulating device in a kind of frock of testing module performance behind the COG, it comprises: pressing plate 1, the web joint that is connected with pressing plate 1 by guide shaft 42, one connect and drive the inside and outside flexible Telescopic handles 5 of this web joint 2 and be arranged at cam 6 on the pressing plate 1 by connecting link 3.
Post the FPC flexible PCB 7 of module to be measured on the lower surface of close web joint 2 one ends of pressing plate 1 with double faced adhesive tape.Guide shaft 4 connects pressing plate 1 and web joint 2, make both keeping parallelism degree, guarantee when regulating Telescopic handle 5, to have between the web joint 2 and pressing plate 1 gap of compactness, and make pressing plate 1 drive web joint 2 motions, make to be attached to the up and down and LCDs LCD electrode contact that top FPC flexible PCB 7 can pull by pressure or to separate.
Connecting link 3 one ends are fixed on the web joint 2, and the other end is fixed on the Telescopic handle 5.This Telescopic handle 5 is pushed along direction shown in Fig. 1 arrow, stretches inside and outside direction shown in Fig. 2 and Fig. 3 linear arrow thereby make connecting link 3 drive web joint 2.When FPC flexible circuit plate electrode and LCDs LCD electrode carry out contraposition, Telescopic handle 5 is pushed back, and whether connecting link 3 drives web joint 2 near the withdrawal of pressing plate 1 one sides, make things convenient for camera 10 to watch the electrode contraposition and accurately carry out, to carry out the adjustment of position, make it alignment.
This device also includes a camera 10.
When display module is tested, at first Telescopic handle 5 is retracted, semi-manufacture display module 11 to be measured is fixed in another regulating device.
Handle on the cam 69 is pressed down, drive pressing plate 1, make FPC flexible PCB 7 touch test module 11, utilize camera 10 to check whether contraposition is accurately carried out.
After using electrode that another regulating device makes FPC flexible PCB 7 and LCDs LCD electrode overlapping, Telescopic handle 5 is released, elastic caoutchouc 8 is pressed in adjust the FPC flexible circuit plate electrode after the contraposition accurately to overlap the place with LCDs LCD electrode.
Pull handle 9 on the cam 6 to equidirectional once more, make under the effect of pressure of FPC flexible circuit plate electrode elastic caoutchouc 8, closely contact LCDs LCD electrode and keep its reliable connection.
These display module 11 performances are detected, and detection will be drawn on the handle on the cam 69 after finishing, playback cam 6, and pressing plate 1 returns to original position.
Claims (5)
1, the pressing plate regulating device in a kind of frock of testing module performance behind the COG, it is characterized in that it comprises: the web joint that a pressing plate, is connected with this pressing plate by a guide shaft, connects and drives flexible Telescopic handle and inside and outside this web joint by a connecting link and is arranged at cam on this pressing plate.
