Abstract
The invention relates to a small PITCH display screen detection device comprising a PVC board and a pressing board. The pressing board is connected and fixed on the surface of the PVC board through a pin shaft and can upwardly and downwardly overturn around the connecting point. A display screen placing area is arranged at the center of the PVC board, the pins of a display screen are limited by two grooves which are arranged in parallel, and conductive rubber strips are arranged in the grooves. A backlight source is arranged in the PVC board and positioned in the middle of the product placing area. An electrical test board is also arranged in the PVC board so that the electrical test board and the pins of the display screen are conductively connected through the conductive rubber strips, and an electrical test machine and a power supply are also connected. A square hole is arranged on the pressing board in a way of being corresponding to the product placing area on the PVC board. Rubber gaskets are arranged at the left and right sides of the square hole in parallel. The problem of deformation of the pins in detection of the small PITCH display screen can be effectively solved so that the detection quality can be guaranteed and the production line detection efficiency can be enhanced.

Technical field
The present invention relates to information display screen detection technique field, a kind of small PITCH display screens detection tool is specifically disclosed.
Background technology
At present, small PITCH display screens detection difficulty is larger, and directly display screen and pin are extruded with hand during detection, easily causes pin deformation, is difficult to show entirely, and Detection results are not obvious, it is difficult to ensure that product quality；And pin deformation is multiple, producing line detection efficiency is had a strong impact on.
The content of the invention
It is an object of the invention to：A kind of anti-pin deformation is provided to solve problem above, it is ensured that detection quality, the small PITCH display screens detection tool of raising producing line detection efficiency.
The technical solution adopted in the present invention is such：
A kind of small PITCH display screens detection tool, including PVC board and pressing plate, the pressing plate is connected and fixed on the PVC board surface by bearing pin, and can be spun upside down around the tie point；The PVC board center is provided with display screen rest area, it is spacing to display screen pin by the twice groove be arrangeding in parallel, it is provided with conductive adhesive tape in the groove；Inside the PVC board, product rest area middle setting have backlight；Electrical measurement plate is additionally provided with inside the PVC board, the electrical measurement plate and display screen pin is on the one hand connected by the conductive adhesive tape, on the other hand connection electric logging device and power supply；Product rest area is provided with square hole in the correspondence PVC board on the pressing plate, and rubber cushion is arranged with parallel in the square hole left and right sides.
Further, in described PVC board one end, integrated setting has pin shaft hole, correspondingly, pin shaft hole is also equipped with the integration of described pressing plate one end, and both are by the interspersed connection of bearing pin.
Further, depending on the distance between groove described in twice is according to the distance between display screen pin.
Further, the pressing plate length is not shorter than the length of the PVC board.
Further, pressing plate spacing preiection is provided with the PVC board, correspondingly, correspondence position is provided with spacing hole on the pressing plate.
In sum, due to using above-mentioned technical proposal, the beneficial effects of the invention are as follows：
