Description
Technical field
The present invention relates to the surface inspecting apparatus of backlight module in a kind of electronic technology, particularly relate to a kind of viscosity welding automatic turning abutted equipment when backlight module light-emitting area automatic absorbing checks.
Background technology
One of key part and component that backlight module (Backlightmodule) is panel of LCD (LCDpanel), owing to liquid crystal itself is not luminous, namely the function of backlight module is in that well-off brightness and the light source being evenly distributed so that it is can normal show image.LCD is mainly made up of colored filter, backlight module, driving IC, the compensation spare part such as film and Polarizer, glass substrate, ito film, alignment film, control circuit, owing to liquid crystal panel itself does not have the characteristics of luminescence, the function of display must be reached with backlight module, LCD manufacturer is after producing face glass, must first in conjunction with colored filter, pour into liquid crystal after both sealings, then with backlight module, drive the assembly such as IC, control circuit plate, be combined into LCD module.Backlight module is mainly formed by assembling components such as light source, lampshade, reflecting plate, light guide plate, diffusion sheet, brightness enhancement film and housings, backlight module mainly offer liquid crystal panel is uniform, the light source of high brightness, ultimate principle is by conventional point or linear light sources, changes into the area source product of high brightness and homogeneous briliancy through succinct effectively light mechanism.General structure is utilize the linear light sources of cold-cathode tube to be reflected cover to enter light guide plate, and transition lines distribution of light sources uniformly area source, then through the equal light action of diffusion sheet with the light harvesting effect of prismatic lens to improve the height of light source and all to spend together.But, due to surface blot, scrape the generation injuring foreign body and cause the appearance of a large amount of defective products, accordingly, it would be desirable to design a series of surface examining device and whether there is surface blot to the surface checking backlight module, scrape and injure foreign body.
In prior art, powered by the power supply of 100V～240V, backlight module is irradiated checking the surface blot of backlight module light-emitting area, scrapes and injure foreign body by the lighting mode adopting HID electronic type, but there is shortcomings in this kind of mode: one, this equipment volume of prior art is too big, takies area of work too big；Two, breakdown maintenance cost is too high；Three, the supply voltage of use is too high, it is easy to the personal safety of crisis user of service；Four, the light that this kind of lighting mode irradiates out, causes eye strain to the personnel of long working.And, under lighting state, backlight module light-emitting area adopted roller to press attached inspection, there is missing inspection, and the drawback that can't check uses roller the number of working processes, by roller pressure inspection more than 10 seconds；Roller pressure inspection is bad, and roller can not stop for a long time, the bad phenomenon that missing inspection very easily occur, can't check.
Summary of the invention
The present invention is on the basis of above-mentioned drawback, provide a kind of viscosity welding automatic turning abutted equipment when automatically detecting for backlight module light-emitting area, this equipment is automatically controlled by cylinder, utilize light-emitting area absorption principle inspection, not only check that efficiency is high, inspection result is high-visible, and easy and simple to handle, it is to avoid missing inspection, the phenomenon that can't check.
A kind of viscosity welding automatic turning abutted equipment of the present invention, including: cylinder, the top board of fixing cylinder, portable plate, by the upper tool that portable plate connects, base and the device lower tool on base, it is characterised in that: described top board is connected on base by four guide rods, and is relatively fixed；Portable plate is connected to the tail end of cylinder, and between top board and base, the lower end device of portable plate has upset cylinder.
Described portable plate is movably connected on guide rod by lead, cylinder can drive portable plate and upset cylinder to move up and down along lead, and described lead is provided with bearing with portable plate junction, side, portable plate lower end is provided with two bracers, upper tool is connected on this bracer by rotating shaft, and can pass through the rotation of rotating shaft relative support block.
Described upper tool upper surface side is provided with top ear, it is positioned at the back side of tool, front is used for adsorbing viscosity welding, band upset cylinder can pass through to push up the upper tool of ear upset, when cylinder is in contraction state, portable plate and upset cylinder are located close to the position of top board, the top now overturning cylinder heads on top ear, when cylinder progressively stretches, the relative top board of portable plate moves down, upset cylinder stretches simultaneously, promote top ear, and then drive upper jig rotation to move down, when rotation makes upper tool front slightly downward, rotary cylinder is retracted, under gravity, that upper tool moves down while continuing to downwardly turn over, until front fully towards under.
Being provided with pressure switches a, pressure switches b, air-breathing switch on described base, pressure switches a, b control upset cylinder and cylinder, tool air-breathing under air-breathing on-off control respectively, and described lower tool is fixed on base, and corresponding with the upper tool position pressed down；When cylinder shrinks, portable plate drives and moves on upper tool, separates with lower tool；When cylinder extends, starting the upset upper tool of cylinder upset, portable plate drives upper tool to fasten with lower tool simultaneously, and on upper tool, the viscosity welding of absorption sticks on backlight template under fastening pressure, then starts air-breathing switch, to tool air-breathing.
The described side on lower tool is provided with locating dowel, and when portable plate drives and presses under upper tool, this locating dowel can make down the upper tool pressed and lower tool contrast fastening, and position is accurate；And top board corresponding with upper and lower tool while being provided with yellow light LED lamp, when start this equipment time, this yellow light LED lamp is bright, for detection backlight module provide light source.
During detection, backlight module is placed on lower tool, upper tool adsorbs one piece of " mouth " type viscosity welding, start this equipment, then pressure switches a and pressure switches b is started, cylinder promotes portable plate to move down, upset cylinder promotes top ear simultaneously, tool upset in drive, namely portable plate drives upper tool to move down and overturn, until fastening on lower tool, after fastening compression, on upper tool, the viscosity welding of absorption sticks on backlight template under fastening pressure, start air-breathing switch, its inner air is extracted out by the protecting film utilizing backlight module with tool gluing, sealing, the bad problem of light-emitting area can be checked clearly when yellow light LED lamp is lighted.
The test mode of this viscosity welding automatic turning abutted equipment is: coordinated by device structure; the upper and lower tool of automatic buckling; and by upper tool, viscosity welding is sticked on backlight template; and fasten closely reliable; protecting film and the tool of backlight module match; adopt air-suction; start air-breathing switch; light-emitting area under lighting state is evacuated rapidly and checks the bad problem points of light-emitting area; after extracting air out; automatically by backlight module light-emitting area pressing, its light-emitting area bad (white point, bright spot, bright line, injured, stain) can be checked.This inspection equipment does not use other tool contact backlight module, cylinder is adopted to promote tool on automatic inlaid, withhold effective, and checking process not damaged, avoiding because checking the phenomenon causing damage and then causing light-emitting area bad, the pressure inspection of this inspection equipment relatively roller is reliable, and efficiency is high, reducing the laminating of openning viscosity welding bad, its precision reaches 0.05mm；Save man-hour, within about 9 seconds, can fit, attach qualification rate 100% for every.
