Abstract
The utility model discloses an adsorption inspection device of the light emitting surface of a back light module. The adsorption inspection device comprises an upper fixture and a lower fixture which is snapped to the upper fixture. The adsorption inspection device is characterized in that the circumference of the inner side of the lower fixture is provided with side suction holes and the side suction holes of the lower fixture are corresponding to side suction holes of the upper fixture after the upper fixture is snapped to the lower fixture. The back light module is placed between the upper fixture and the lower fixture during inspection, air is sucked from the vacuum suction opening and the side suction holes through an air suction device, namely that the air inside the back light module is sucked out due to the fact that a protective film of the back light module and the fixtures are sealed in an adhered mode, and the problems of the light emitting surface can be inspected out clearly in a lighting state. According to the adsorption inspection device of the light emitting surface of the back light module, other fixtures are not in contact with the back light module, no damage is caused in the inspection process, the bad light emitting surface caused by the inspection damage is avoided, the adsorption inspection device is reliable and high in efficiency in comparison with roller pressure inspection, the inspection can be achieved within 2 to 3 seconds through the adsorption pressure inspection, and the detection rate of the light emitting surface reaches 100%.
Description
Technical field
The utility model relates to the surface inspecting apparatus of backlight module in a kind of electronic technology, relates in particular to the equipment that a kind of backlight module light-emitting area absorption checks.
Background technology
Backlight module (Back light module) is one of key part and component of panel of LCD (LCD panel), because liquid crystal itself is not luminous, the function of backlight module is well-off brightness and the light source being evenly distributed, normally show image.LCD panel is mainly comprised of spare parts such as colored filter, backlight module, drive IC, compensate film and Polarizer, glass substrate, ITO film, alignment film, control circuits, because liquid crystal panel itself is not had a characteristics of luminescence, must reach with backlight module the function of demonstration, LCD panel manufacturers is after producing face glass, must be first in conjunction with colored filter, both pour into liquid crystal after involution, then with the assemblies such as backlight module, drive IC, control circuit board, be combined into LCD module.Backlight module is mainly assembled by assemblies such as light source, lampshade, reflecting plate, light guide plate, diffusion sheet, brightness enhancement film and housings, backlight module be mainly to provide liquid crystal panel evenly, the light source of high brightness, ultimate principle is by conventional point or linear light sources, sees through the area source product that succinct efficient light organisation conversion becomes high brightness and homogeneous briliancy.General structure is to utilize the linear light sources of cold-cathode tube to enter light guide plate through reflex housing, and transition lines distribution of light sources becomes uniform area source, then does in order to improve the height of light source and all to spend together through the equal light action of diffusion sheet and the light harvesting of prismatic lens.But, due to surface blot, scrape the appearance that the generation that injures foreign matter causes a large amount of defective productss, therefore, need to design the surface that a series of surface examining device checks backlight module and whether have surface blot, scrape and injure foreign matter.
In prior art, Power supply by 100V～240V, the mode of lighting a lamp that adopts HID electronic type to backlight module irradiate to check backlight module light-emitting area surface blot, scrape and injure foreign matter, but there is shortcomings in this kind of mode: one, this equipment volume of prior art is too large, takies area of work too large; Two, breakdown maintenance cost is too high; Three, the supply voltage of use is too high, easily crisis user of service's personal safety; Four, the light that this kind mode of lighting a lamp irradiates out, causes eye tired to the personnel of long working.And backlight module light-emitting area adopts roller to press attached inspection under lighting state, exist undetectedly, the drawback can't check, is used roller the number of working processes, by roller, presses inspection more than 10 seconds; Roller presses inspection bad, and roller can not stop for a long time, very easily occurs bad phenomenon undetected, that can't check.
Summary of the invention
The utility model, on the basis of above-mentioned drawback, provides a kind of checkout facility for backlight module light-emitting area, and this equipment checks by light-emitting area absorption principle, not only checking efficiency is high, check result is high-visible, and easy and simple to handle, has avoided phenomenon undetected, that can't check.
A kind of backlight module light-emitting area absorption checkout equipment described in the utility model, comprise: upper tool, lower tool with upper tool fastening, it is characterized in that: the inside circumference of lower tool is provided with side suction hole, side suction hole connects mutually, lower tool one side is provided with static link, the upper right corner is provided with tong, near tong place device, there is pcb board, centre is provided with vacuum suction mouth, lower tool bottom is provided with footing, bottom side is provided with switch, after upper tool and lower tool fasten, the side suction hole of lower tool is corresponding with the side suction hole of upper tool, under control ambilateral get product keep away a breach with on control and ambilaterally get product to keep away a breach corresponding.Backlight module is placed between tool and lower tool, by tong and side, is fastened and is compressed.Air-breathing from vacuum suction mouth and side suction hole with air extractor; utilize the diaphragm of backlight module with tool gluing, sealing, its inner air to be extracted out; light a lamp and can check out the bad problem of light-emitting area under state clearly, two ends arrange gets product and keeps away in a breach handled easily process and place, take out backlight module.
Diaphragm and tool that the test mode of this backlight module light-emitting area absorption checkout facility is backlight module match; adopt air-suction; light-emitting area under lighting state is evacuated rapidly to check out the bad problem points of light-emitting area; after deflating; the pressing of backlight module light-emitting area, can check its light-emitting area bad (white point, bright spot, bright line, injured, stain).This checkout facility does not use other tool contact backlight module, checking process not damaged, avoided causing damage and then causing the bad phenomenon of light-emitting area because checking, this checkout facility presses inspection reliable compared with roller, and efficiency is high, adsorption pressure inspection 2-3 can complete inspection second, and light-emitting area recall rate reaches 100%.
