The device in the invention has novel structure, simple and convenient operation, rapidness and effectiveness, and can greatly reduce the ratio of unqualified products caused by the glass chips, thus improving the production efficiency and lowering the production cost.
Description
Technical field
The present invention relates to a kind of cleaning device, the device of particularly a kind of automated cleaning liquid crystal display surface and line scan pickup coil side chips of glass.
Background technology
The structure of LCD (LCD) comprises that mainly two are provided with glass substrate, polarizer, the alignment film outside the two sheet glass substrates of transparency electrode and are clipped in the liquid crystal between alignment film.Glass substrate is under cold situation, and the liquid crystal molecule between alignment film does not rotate, and light can pass through liquid crystal layer and polarizer smoothly, is shown as bright attitude; When glass substrate was connected to external power source, liquid crystal molecule rotated under electric field action, and light can not pass through liquid crystal layer and polarizer, is shown as dark attitude.To the zone design electric field that needs display pattern on the glass substrate, can needing obtain the pattern of demonstration through the rotation of control area of the pattern liquid crystal molecule.
The general manufacture process of LCD is following: at first on glass substrate, need the zone of display pattern to make electrode; Again the glass baseplate surface that electrode is arranged apply as macromolecular materials such as polyimides with the formation alignment film, and friction treatment carried out on the alignment film surface make liquid crystal molecule on alignment film, have tilt angle; The glass substrate cutting that to fit is in pairs then injected liquid crystal and is sealed liquid crystal injecting port in the glass sylphon again; Attach polarizer in the glass substrate outside at last, just form a complete LCD.
In the above-mentioned processing procedure of LCD, cutting is one of them very crucial operation.At present, industry generally adopts the infiltration type break bar to cut.The infiltration type break bar has laciniation, and break bar is imposed on certain pressure when the glass baseplate surface, and break bar forms the cutting crackle at substrate surface, and the crackle further growth causes the glass season crack, and this is our needed result.But the infiltration type break bar can produce destroy glass substrate, and the result produces a large amount of chipss of glass, and segment glass bits (like size greater than 1 micron but less than 100 microns chip) irreversibly stick on liquid crystal display surface and the line scan pickup coil side.These a large amount of tiny glass chip have a very high display surface and the risk of drawing outage polar curve road of stabbing, simultaneously to the sliver after the cutting, irritate brilliant, seal, test, cleaning, Bang Ding and paster operation also be very disadvantageous.Owing to a large amount of use metals to make width to be merely several microns fine and closely woven electrode circuit, therefore, it is higher that the electrode circuit is drawn disconnected possibility by chips of glass in Thin Film Transistor-LCD (TFT-LCD) element.
To sum up, mainly there is following harm in chips of glass to the manufacture process of LCD:
(1) the workshop cleanliness factor worsens, and liquid crystal is contaminated when injecting liquid crystal;
(2) chips of glass is drawn outage polar curve road, increases product electrical property defective;
(3) cleaning agent is contaminated, increases to change the frequency and cleaning agent cost;
(4) polaroid attaches bad rising;
(5) corrosion appears in product, and client's complaint increases.
At present, the operation that all immediately the chips of glass of product surface and line scan pickup coil side is cleaned after the cutting in the processing procedure of the most of LCD of industry factory increases the purpose that the product wash number reaches the removal chips of glass and be selected in the processing procedure.The shortcoming of this processing method is following: matting pressure increases in the processing procedure, and production efficiency reduces, and cleaning agent is prone to contaminated and the cost increase; Product is through after repeatedly cleaning, and reliability of products can not get due assurance.
Some LCD factories use the artificial monolithic of air gun to blow the pouring product in dust free room behind the glass-cutting substrate, perhaps install in the pass-through box between workshop and workshop and blow shower device, in the carrying product process chips of glass on the product are cleaned.More than in two kinds of methods, the former shortcoming is that efficient is lower, control accuracy is relatively poor, the technology management and control is difficult, also causes the manpower waste simultaneously, the chips of glass that also can cause the dust-free workshop environment to be kicked up pollutes; The latter's shortcoming is that clean housing reform causes this increase, the equipment fault inconvenient maintenance, and the chips of glass cleaning effect is difficult to guarantee that chips of glass entering dust free room air conditioner circulating system causes whole dust free room cleanliness factor to worsen.
Summary of the invention
The purpose of this invention is to provide a kind of liquid crystal display surface and line scan pickup coil side chips of glass automatic cleaning apparatus, novel structure, easy and simple to handle, fast and effectively, reduce the bad product ratio that causes because of chips of glass greatly, thereby enhance productivity, reduce production costs.
