Abstract
The invention discloses a backlight module foreign matter inspecting method. A backlight module is maintained by using a transparent plate the size of which is consistent to that of a light-emitting surface of the backlight module and a power device with adjustable pressure. The backlight module foreign matter inspecting method specifically comprises the following steps: laminating the transparent plate with the light-emitting surface; applying pressure to the transparent plate by virtue of the power device so as to extrude the backlight module; observing whether the light emitting surface has a foreign matter by virtue of the transparent plate; and maintaining the backlight module on which the foreign matter is inspected. In the backlight module foreign matter inspecting method, the backlight module is extruded by the transparent plate laminated on the light-emitting surface of the backlight module, so that the foreign matter in the backlight module is diffused under a pressure action, an operator can observe the foreign matter through the transparent plate, and thus the backlight module containing the foreign matter is prevented from inflowing a qualified product to avoid loss of complete installation.
Description
Technical field
The present invention relates to back light model setting technology field, particularly relate to a kind of backlight module filth test method.
Background technology
Comprehensively universal along with intelligent mobile phone, and the continuous innovation of technology, mobile phone products presents the feature such as renewal, cheapization, quality severization fast, and the competition of each large handset manufacturers is also growing more intense.In this context, price becomes the strong weapon defeated one's opponents undoubtedly.Low cost becomes the problem that everybody more and more pays close attention to.Based on more than, cost pressure is also just distributed on the body of each mobile phone components supplying business.
As everyone knows, the assembling of backlight requires high to the cleanliness of material, environment, and atomic little foreign matter, as long as human eye is obviously visible, is nearly all regarded as bad.But zero foreign matter management and control, any backlight factory all cannot accomplish, as the diaphragm 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 great loss.In current industry, the light-emitting area filth test of backlight mainly relies on human eye to identify, some obvious foreign matters still can easily find, but have foreign matter to be greatly difficult to detect, as cull, sebum bits, flexible plastic rubber material etc., the volume of these foreign matters own is very little, not easily find, but through transport or assembling complete machine, can External Force Acting be subject to, enlarged areas, forms macroscopic foreign matter bad.
Summary of the invention
Based on the technical matters that background technology exists, the present invention proposes a kind of backlight module filth test method.
A kind of backlight module filth test method that the present invention proposes, by one piece of propulsion system with the light-emitting area of backlight module transparent panel of the same size and a pressure adjustable, backlight module is overhauled, specifically comprise the following steps:
Transparent panel and light-emitting area are fitted;
Pressure is applied thus extruding backlight module to transparent panel by propulsion system;
Observe light-emitting area by transparent panel and whether have foreign matter;
Overhaul checking out the backlight module of foreign matter.
Preferably, execute in stressed process by propulsion system to transparent panel, light-emitting area uniform stressed.
Preferably, transparent panel is acrylic board.
Preferably, propulsion system adopt manpower or machine power.
In the present invention, by being fitted in the transparent panel extruding backlight module in the light-emitting area of backlight module across one piece, thus spread under making the pressure effect of the foreign matter in backlight module, make operator observe foreign matter by transparent panel, thus avoid the backlight module containing foreign matter to flow in certified products carrying out whole machine installation causing damage.
Backlight module filth test method provided by the invention, can before final assembly, detect the foreign matter in backlight module in time, be conducive to promoting defective products recall rate, avoid the cost consumption that complete machine is reprocessed, improve backlight module qualification rate, promote client qualification rate and reduce rework cost, thus improve complete machine production efficiency, reduce costs.
Accompanying drawing explanation
Fig. 1 is backlight module and transparent panel independence schematic diagram;
Fig. 2 is that backlight module and transparent panel assemble schematic diagram;
Fig. 3 is a kind of backlight module filth test method flow diagram that the present invention proposes.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of backlight module filth test method that the present invention proposes, is overhauled backlight module 1 by one piece of propulsion system with the light-emitting area 2 of backlight module 1 transparent panel 3 of the same size and a pressure adjustable.
In present embodiment, transparent panel 3 is acrylic board, so that the observation to foreign matter in backlight module 1.During concrete enforcement, also can adopt other perspectivity materials.
A kind of backlight module filth test method that the present invention proposes specifically comprises the following steps:
Step one, transparent panel 3 and light-emitting area 2 to be fitted.
Step 2, by propulsion system to transparent panel 3 apply pressure thus extruding backlight module 1.
In this step, execute in stressed process by propulsion system to transparent panel 3, light-emitting area 2 answers uniform stressed, avoids unbalance stress to cause damage to light-emitting area 2.So, due to the transitional function of transparent panel 3, avoiding exerts a force directly to light-emitting area 2 causes damage to light-emitting area 2.In addition, because transparent panel 3 and light-emitting area 2 are in the same size, transparent panel 3 and light-emitting area 2 more can ensure light-emitting area 2 uniform stressed after fitting.
In present embodiment, propulsion system adopt manpower, namely by operator's Manual press transparent panel 3, easy to operate, with low cost.During concrete enforcement, propulsion system also can adopt machine power, to ensure the reliability homogeneity exerted a force further.
Step 3, observe light-emitting area 2 by transparent panel 3 and whether have foreign matter.
Due to transparent panel 3 can perspectivity, in the process of extruding backlight module 1, just can observe directly foreign matter, be conducive to the real-time and the validity reliability that ensure filth test.
Step 4, to checking out the backlight module 1 of foreign matter to overhaul.
Utilize the detection method that present embodiment provides, before final assembly, the foreign matter in backlight module 1 can be detected in time, avoid the cost consumption that complete machine is reprocessed, improve backlight module 1 qualification rate, thus improve complete machine production efficiency, reduce costs.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
