The test fixture of the conventional PCB 1+ conductive rubber strip 2 can not position the edge of the LCD 4, and can not detect the slight deviation of the pin installation. The LCD screen needs to be pressed by force during testing, otherwise, the LCD cannot be powered up reliably, but the problems of pin deformation, poor contact of certain pins and the like are easily caused by pressing the LCD by force.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned problem that conventional LCD test fixture exists, the utility model provides a novel LCD test fixture.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the upper surface of the base is of an inclined plane structure, the front part of the upper surface of the base is provided with an LCD mounting seat with the upper surface parallel to the upper surface of the base, and the upper surface of the LCD mounting seat is provided with a clamping groove for fixing an LCD; lie in LCD mount pad rear portion installation fixing base on the base, sliding mounting and base upper surface parallel's connecting rod in the fixing base, the anterior erection joint seat of connecting rod, the probe that the pin position of connecting seat front side and LCD corresponds, the LCD detector is connected through electrically conductive winding displacement to the probe, and the handle is connected to the connecting rod rear end.
And the front side of the connecting seat is provided with a probe through a probe mounting plate.
And the front side of the connecting seat is provided with a limiting plug matched with a limiting hole in the LCD mounting seat through a plug mounting plate.
The rear end of the connecting rod is connected with one end of the connecting plate through the third connecting shaft, the other end of the connecting plate is connected with the handle through the second connecting shaft, the lower end of the handle is connected with the fixing plate through the first connecting shaft, and the fixing plate is installed on the rear portion of the upper surface of the base.
The utility model discloses a LCD test fixture can add the effectual LCD pin installation off normal that detects out of electric mode through LCD edge orientation and probe. Meanwhile, the LCD does not need to be manually pressed in the test, so that the bending deformation of the pins can be effectively avoided, meanwhile, the interference of human factors on the LCD test is reduced, and the problems of poor pin contact and the like are avoided.

Detailed Description
The utility model discloses a LCD test fixture, LCD edge are fixed a position through spacing draw-in groove, and the LCD pin is gone up through side probe contact, does not need the tester to carry out manual the pressing during the test. The specific structure is shown in fig. 3 and 4.
The upper surface of the base 22 is of an inclined plane structure, an LCD mounting seat 6 with the upper surface parallel to the upper surface of the base 22 is arranged in front of the upper surface of the base 22, and a clamping groove 7 for fixing an LCD 4 is arranged on the upper surface of the LCD mounting seat 6; lie in 6 rear portion installation fixing base 11 of LCD mount pad on the base 22, sliding installation and base 22 upper surface parallel's connecting rod 12 in the fixing base 11, connecting rod 12 front portion erection joint seat 19, 19 front sides of connecting seat pass through probe mounting panel 9 installation and the corresponding probe 8 of LCD 4 pin position, probe 8 passes through electrically conductive winding displacement 10 and connects the LCD detector, 19 front sides of connecting seat pass through plug mounting panel 20 installation and LCD mount pad 6 interior spacing hole assorted limit plug 21, connecting rod 12 rear end passes through the one end that third connecting axle 18 connects connecting plate 15, the other end of connecting plate 15 passes through second connecting axle 14 connection handle 13, handle 13 lower extreme passes through 16 connection fixed plate 17 of first connecting axle, fixed plate 17 installs in base 22 upper surface rear portion.
When the device is used, the front and back movement of the handle 13 drives the connecting rod 12 to move back and forth, so that the contact electrification of the probe 8 and the LCD pin is realized, and the pin is bent due to the overlarge extrusion force on the pin by the limiting effect of the insertion depth of the limiting plug 21 in the LCD mounting seat. In addition, the LCD is fixed on the LCD mounting seat 6 through the clamping groove 7, and the position deviation of pins is placed. The LCD pin installation deviation is effectively detected through the LCD edge positioning and the probe power-on mode. Meanwhile, the LCD does not need to be manually pressed in the test, so that the bending deformation of the pins can be effectively avoided, the interference of human factors to the LCD test is reduced, and the outflow of the problems of poor pin contact and the like is avoided.
