Description
Technical field
The present invention relates to liquid crystal display module field, particularly relate to filth test device and the method for inspection of a kind of liquid crystal display module.
Background technology
Comprehensively universal along with intelligent mobile phone, and the continuous innovation of technology, mobile phone products presents the quickly feature such as renewal, cheapization, quality severization, and the competition of each big handset manufacturers is also growing more intense.It is known that the cleannes to material, environment that assemble of the liquid crystal display module of mobile phone require high, atomic little foreign body, as long as human eye is it is apparent that be nearly all considered bad.But zero foreign body management and control, any module factory all cannot accomplish, as the protecting film on each blooming can produce cull, the sebum bits etc. that Manufacturing Worker drops, once defective products flows into client, after assembling complete machine, can cause loss greatly.At present in industry, the light-emitting area filth test of liquid crystal display module mainly relies on human eye to be identified, some obvious foreign bodies still can easily find, but there is substantial portion of foreign body to be difficult to detect, such as cull, sebum bits, flexible plastic rubber material etc., the volume of these foreign bodies own is the least, it is difficult to find, but through transport or assembling complete machine, macroscopic bad foreign body can be formed by External Force Acting, enlarged areas, and reprocess the most again and obviously can spend the biggest manpower and materials, and impact to the quality etc. of product.
Summary of the invention
It is an object of the invention to the defect existed for above-mentioned prior art, it is provided that the filth test device of a kind of liquid crystal display module and the method for inspection.
The technical solution used in the present invention is, design the filth test device of a kind of liquid crystal display module, display surface including one Yu liquid crystal display module is in the same size and is arranged on the lamella lucida of display surface side, and a soft roller and being arranged on the liquid crystal display module back side is connected the power set of controllable pressure size with soft roller.
The invention allows for a kind of filth test method of liquid crystal display module, comprise the following steps:
(1) lamella lucida is placed on the display surface side of liquid crystal display module；
(2) use at the liquid crystal display module back side a soft pair of rollers liquid crystal display module to apply external force, foreign body is flattened and amplifies；
(3) by lamella lucida, liquid crystal display module display surface is tested；
(4) the liquid crystal display module of detection foreign body is reprocessed.
In one embodiment, described lamella lucida is acrylic board, and the external sheath of described soft roller has one layer of rubber layer, and described power set use machine power.
Described power set can drive with manpower in some cases and substitute.
Compared with prior art, the invention have the benefit that by using filth test device to make its internal foreign body area amplify liquid crystal display module applying pressure, coroner is helped to check the sightless bad foreign body with certain volume of naked eyes in liquid crystal display module, ensure the low bad foreign body of liquid crystal display module, decrease the fault rate of liquid crystal display module, reduce and reprocess cost, and the design of verifying attachment structure is simple, practical.

Fig. 1 is the schematic diagram of liquid crystal display module display surface；
Fig. 2 is the schematic diagram of liquid crystal display module side；
Fig. 3 is the schematic diagram at the liquid crystal display module back side；
Fig. 4 is that liquid crystal display module layers of material stacks schematic diagram；
Fig. 5 is filth test device of the present invention and operation principle schematic diagram.
Detailed description of the invention
With embodiment, invention is described in detail below in conjunction with the accompanying drawings.
The display surface of liquid crystal display module, side and the schematic rear view that Fig. 1-Fig. 3 respectively assembles.Fig. 4 is that liquid crystal display module layers of material stacks schematic diagram。Fig. 4 is from top to bottom respectively upper polaroid 101, LCD 102, lower polaroid 103, photomask 104, upper bright enhancement film 105, lower bright enhancement film 106, lower diffusion barrier 107, light guide plate 108, glue frame 109, reflector plate 110.Owing to the structure of liquid crystal display module forms complexity, and it mostly is blooming piece, therefore its cleannes are required the highest.
As shown in Figure 5, the filth test device of liquid crystal display module that the present invention proposes includes: one is in the same size with the display surface of liquid crystal display module 1 and be arranged on the lamella lucida 2 of display surface side, and a soft roller 3 and being arranged on liquid crystal display module 1 back side is connected the power set of controllable pressure size with soft roller 3.
Filth test device based on above-mentioned liquid crystal display module, the invention allows for a kind of filth test method of liquid crystal display module, specifically includes following steps:
(1) lamella lucida 2 is fitted on the display surface of liquid crystal display module 1, and by the back side of liquid crystal display module 1 being placed in a plane outwardly；
(2) soft roller 3 is placed in the back side of liquid crystal display module 1, power set are used to drive soft roller 3 to roll at the back side of liquid crystal display module 1, the size of the power being applied on power set is in the maximum magnitude ensureing to weigh wounded liquid crystal display module internal material, applies pressure to liquid crystal display module 1 by soft roller 3；
(3) observing liquid crystal display module through lamella lucida 2, if having observed when enlarged areas is to macroscopic foreign body because of pressure, then judging that this liquid crystal display module is defective work；
(4) will verify that the liquid crystal display module having foreign body is reprocessed.
In the present embodiment, lamella lucida 2 is acrylic board, and those skilled in the art are also dependent on needing to select the lamella lucida of other materials。The external sheath of soft roller 3 has one layer of rubber layer, and those skilled in the art also can select other soft materials the most as required。The axle center 4 of soft roller 3 connects a mechanical driver unit, and this mechanical driver unit drives soft roller 3 to extrude the back side of liquid crystal display module.In some cases, this Power Drive Unit can also apply to substitute with manpower.
The filth test device of present invention design and the method for inspection, its internal foreign body area is made to amplify by liquid crystal display module applies pressure, coroner is facilitated to check the sightless bad foreign body with certain volume of the part naked eyes in liquid crystal display module, ensure the low bad foreign body of liquid crystal display module, decrease the fault rate of liquid crystal display module, reduce and reprocess cost, and the design of verifying attachment structure is simple, practical.
Above-described embodiment is merely to illustrate the detailed description of the invention of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and change, these deformation and change all should belong to protection scope of the present invention.
