Abstract
The utility model provides a connecting device of a liquid crystal display quality testing device. The connecting device comprises a pressing plate and a conductive glue stick. The conductive glue stick is provided with a plurality of conducting rings which can respectively correspond to connecting electrodes of a liquid crystal display. The pressing plate is arranged above the conductive glue stick. When the connecting device is used, a liquid crystal display to be tested is placed on a working platform, the conductive glue stick is placed above the connecting electrodes of the liquid crystal display, and the conducting rings are enabled to correspond to the connecting electrodes one by one. The conducting rings are connected with a testing device through a cable, the pressing plate presses down the conductive glue stick to enable the conducting rings and the connecting electrodes of the liquid crystal display to be tightly connected and completely contact, so that testing signals of the testing device can be well input to the liquid crystal display to be tested through the conducting rings. Due to the physical property of the conductive glue stick, when the down force of the pressing plate is exerted on the conductive glue stick, the conductive glue stick can be slightly deformed, and tight connecting and complete contacting of the conducting rings and the connecting electrodes of the liquid crystal display are guaranteed.

Technical field
The utility model belongs to liquid crystal display production testing field, relates in particular to the checkout equipment field of liquid crystal display.
Background technology
LCDs has been brought convenient and practical in the application of every aspect to people, because the characteristic that liquid crystal display itself has, LCDs needs necessary detecting step to guarantee its qualification rate in process of production, adopt card inserting-in mode to carry out to the testing of LCDs in the prior art, so-called card inserting-in mode is the link slot that the stud connector design of checkout equipment is become insertion slot type, the connecting electrode of the LCDs that need are detected inserts in the link slot, then by checkout equipment LCDs is detected, be provided with a plurality of connection shell fragments corresponding with the connecting electrode of LCDs in the link slot, display screen enters in the link slot, described connection shell fragment has downward pressure, force the connection shell fragment closely to be connected with each electrode points of connecting electrode respectively, detect complete afterwards LCDs the taking-up from link slot, the link slot of this type of checkout equipment has three shortcomings:
The connecting electrode of 1 LCDs is subject to the wearing and tearing of at least twice connection shell fragment, because the coating of connecting electrode is very thin, come off easily afterwards frayed, no problem during detection, but coming off of coating causes display screen to become a problem display screen that is labeled as certified products easily when extracting connecting electrode;
2 testing processes also can consist of wearing and tearing to connecting shell fragment, connect the phenomenon that the electrode coating on the shell fragment also can come off after long-term the use, cause easily testing result mistake to occur, it is not enough that shell fragment elastic force also occurs in addition easily, connects to occur virtually connecting the testing result mistake to occur equally;
3 link slots have a plurality of connection shell fragments, and its production cost is higher, have again above-mentioned problem at the 2nd simultaneously, and after problem having occurred, its replacement cost is high, the whole production cost that can improve LCDs.
The utility model content
The purpose of this utility model is to provide a kind of coupling arrangement of liquid crystal display quality inspection equipment, and the connecting electrode that is intended to solve LCDs in the prior art is subject to the problem of the link slot wearing and tearing of checkout equipment easily.
The utility model is to realize like this, a kind of coupling arrangement of liquid crystal display quality inspection equipment is characterized in that, comprises pressing plate and conducting resinl rod, described conducting resinl rod has a plurality of conducting rings that can be corresponding with the connecting electrode difference of liquid crystal display, and described pressing plate is located at the top of described conducting resinl rod.
Preferably, described pressing plate is provided with the pressing plate conductive electrode corresponding with described conducting ring.
Preferably, a lower platen is established in described conducting resinl rod below, and described lower platen and pressing plate are by making lower platen be connected with the flexible member of pressing plate generation clossing pressure.
Use technique scheme, the coupling arrangement of liquid crystal display quality inspection equipment provided by the utility model in use, the liquid crystal display that needs are detected places on the workbench, described conducting resinl rod places the connecting electrode top of described liquid crystal display, and make described conducting ring corresponding one by one with described connecting electrode, described conducting ring is connected with checkout equipment by cable, described pressing plate presses down the conducting resinl rod, impel described conducting ring closely to be connected fully contact with the connecting electrode of liquid crystal display, thereby the detection signal with checkout equipment that can be good is input in the liquid crystal display by described conducting ring and detects, because the physical characteristics of conducting resinl rod own, when being subject to the downforce of described pressing plate, slight deformation can occur in described conducting resinl rod, can guarantee that described conducting ring closely is connected fully contact with the connecting electrode of liquid crystal display; Perhaps, described conducting resinl rod is placed on the workbench, then the connecting electrode with described liquid crystal display is corresponding one by one with the conducting ring of described conducting resinl rod downwards, described pressing plate presses down the back side of described connecting electrode, force described connecting electrode and described conducting ring closely to be connected fully contact, thereby the detection signal with checkout equipment that equally can be good is input in the liquid crystal display by described conducting ring and detects, and has reached the effect of avoiding the liquid crystal display connecting electrode to be worn.
