Above characteristics have determined the requirement to product tester: the test request that needs to satisfy at short notice the different model typical products in mass production; It is many that the device quantity of test is wanted.
The test fixture of product before, what adopt usually is the test fixture of a correspondence of a production, because the interface spacing of different model is different; Under the situation that all size spacing all has, proving installation is incompatible, can not be general mutually; Corresponding test fixture can only be to be used for testing corresponding display screen, if when the batch of production is big, it is not enough frock to occur; Need to make again, very delay the production time, lower efficiency; And the test job of each style, can not reuse or be on the increase the difficulty that causes the waste on the resource and deposit.
Summary of the invention
The utility model has proposed the conversion equipment can compatible different model product tested to above problem, and existences need be incured loss through delay the problem of long product line progress easily to every money different model product customization proving installation before having solved.
The technical scheme of the utility model is: a kind of universal test device of display screen; It is characterized in that; Said device has comprised that A, two part: A of B partly are one of detachable special test patchcord; Comprise dedicated printed circuit board and be positioned at the peripheral resistor-capacitor unit of minority on this plate and the Outlet line of connectivity port, the interface that said detachable special test patchcord can adaptive different spacing; B partly is one of a universal test framework, and said universal test framework is used for installing said detachable special test patchcord, at the built-in drive controlling plate of universal test framework, LED-backlit and geocoded activity piece; Said A, two parts of B are movable is used in combination removably.
Said special test patchcord comprises the Outlet line of PCB dedicated printed circuit board, special purpose interface printed wire and the peripheral circuit and the connectivity port of different spacing.
Said geocoded activity piece fixes the COG display screen of mounting strap FPC, and the fixed position of installation is in the detachable special test patchcord that guarantees on the test frame and is connected with the pad contraposition of the FPC of COG display screen.
Said universal test framework comprises the special-purpose Drive and Control Circuit that is built on the universal test framework, be arranged on LED-backlit on the universal test framework, be used for fixing the depression bar that compresses detachable special test patchcord, the pressure head on depression bar.
The beneficial effect of the utility model: through the interface of the adaptive different spacing of detachable special test patchcord; Detachable special test patchcord is installed on the test frame; And then test; Need not customize the frock different testing devices, save time and resource, increase work efficiency according to product different model and interface spacing size.
