Abstract
The utility model discloses a convenient testing clamp used for an LCD display screen having pins. The testing clamp includes a fully conducting glue tape, a driving IC, a PCB universal board and a mold frame used for fixing the LCD display screen. The PCB universal board is provided with a metal-core-exposed wire electrically. The PCB universal board is connected with the mold frame fixedly. The fully conducting glue tape is disposed on the metal-core-exposed wire. Pins of the LCD display screen are pressed against the fully conducting glue tape. According to the utility model, by adopting the metal-core-exposed wire of the PCB universal board for connecting with the driving IC electrically and by adding the fully conducting glue tape, a testing worker only needs to press the pins against the fully conducting glue tape and to switch on a power source of the driving IC for normal testing of the LCD display screen. By the structure improvement of the testing clamp, a problem that an LCD product having slighted inclined pins cannot be tested since the pins of the LCD screen need to be inserted into a pin header for testing can be solved. The application range is enlarged. Besides, the testing worker can work efficiency and does not need to worry about pin inclination.
Description
Technical field
The utility model relates to the field tests of LCD, relates in particular to a kind of portable test fixture of the PIN of dress formula LCD display.
Background technology
Just dress PIN formula LCD display need to can be carried out shipment after dress PIN pin and some UV pin, in order to reach shipment yield, carries out the test of product before shipment again.At present, tester adopts with PIN apart from the same row's pin, to arrange pin one end is connected with drive IC or drive circuit board, then LCD pin is inserted in row's pin and tested, in use there is following defect in this test mode: when the PIN of LCD display screen pin is neat, such method of testing can't be brought very large difficulty, and much electronic material supplier can provide and PIN pin distance row's pin of a size, if but when LCD display is produced, because gluttonous putting produces the small unrest of PIN pin generating portion, tiltedly, like this when product test, PIN pin need to be turned round to straight cutting enters to arrange in pin, then the row's of reeve pin test, here many quality time of tester have been wasted, cause personnel's utilization factor of module factory not high, test products accuracy is not good.
Summary of the invention
For the weak point existing in above-mentioned technology, the utility model provide a kind of simple in structure, shipment yield is high, work efficiency is high and the portable test fixture of the dress PIN formula LCD display of simple operation.
For achieving the above object, the utility model provides a kind of portable test fixture of the PIN of dress formula LCD display, comprises full conductive adhesive tape, drive IC, PCB generic disk and for the mould frame of fixed L CD display screen; Described PCB generic disk is provided with the leakage gold cabling being electrically connected to drive IC, and described PCB generic disk is fixedly connected with mould frame; Described full conductive adhesive tape is placed on Lou on golden cabling, and the PIN pin of LCD display is crimped on full conductive adhesive tape.
Wherein, in described mould frame, be provided with a groove, the top of described LCD display is contained in this groove, and described PIN pin is crimped on full conductive adhesive tape after extending groove.
Wherein, described PCB generic disk forms after being exposed by LCD film plate.
Wherein, described mould frame is made by optical material.
The beneficial effects of the utility model are: compared with prior art, the portable test fixture of the dress PIN formula LCD display that the utility model provides, adopt the leakage gold cabling of PCB generic disk to be electrically connected to drive IC, and set up full conductive adhesive tape, when test LCD display, only PIN pin need be crimped on full conductive adhesive tape, the power connection of drive IC, product just can proper testing; The improvement of structure on this test fixture, the PIN pin that has solved LCD display inserts test in row's pin and has the phenomenon that cannot test small random, the oblique LCD product of PIN pin generating portion, has expanded usable range.Providing of this fixture makes tester can efficiently utilize the time, needn't be disorderly worried for PIN pin, and also this fixture also has simple operation, efficient and convenient, accuracy rate is higher, applied widely and working effect high.
