Description
Technical field
The present invention relates to FPD industry device, specifically a kind of liquid crystal display printing equipment.
Background technology
Printing machine is the equipment be printed onto by the PI liquid in the galley with PI liquid on glass substrate.In printing process, between glass substrate and galley, adopt the fashion of extrusion of high strength, thus PI liquid is printed onto on glass substrate.If do not have the extruding of high strength, so PI liquid can not be printed onto on glass substrate when guaranteed quality.
Traditional printing machine mainly can be divided into two kinds of tactic patterns:
One, linear printing machine, as Fig. 1, this linear pattern printing machine is moved by the mobile glass substrate that drives of printing platform, thus realize the object of printing.
Linear pattern printing machine mode of operation illustrates:
1. glass substrate is taken out from entering platform by robot (Robot), is sent on printing platform;
2. printing platform moves together with glass substrate, and by the printing of print wheel, now PI liquid will be printed on glass substrate;
3., after being completed for printing, glass substrate is taken away by the robot in downstream;
4. printing platform return, prepares the arrival of next sheet glass substrate;
Realize round-the-clock printing, action repeats 1.-4. step;
Two, Chinese character pin-shaped printing machine, as Fig. 2, this Chinese character pin-shaped printing machine drives galley by the rolling of print wheel, thus realize the object of printing.
Linear pattern printing machine mode of operation illustrates:
1. glass substrate is taken out from entering platform by robot, is sent on printing platform, as Fig. 7;
2. print wheel drives galley to roll, and realizes printing action, as Fig. 8;
3. print wheel return, then glass substrate is removed, and is sent to downstream simultaneously, as Fig. 9;
4. robot is returned to upstream position, waits for the arrival of next sheet glass substrate, as Figure 10;
Realize continuous print printing, action repeats 1.-4. step.
The main distinction of above two kinds of structures is: the result realizing printing object is that printing platform moves, or the pattern that print wheel rolls.
From the motion analysis of above two kinds of modes, no matter be any print structure, when realization printing object, all must extrude through the high strength of galley and glass substrate, the uniform PI face of glass baseplate surface one deck could be formed.
But, often there will be before printing in real production process, glass substrate can exist some foreign matters, or printing platform can exist some foreign matters.If these foreign matters are not effectively removed before printing, well imagine, in printing process, the high strength extrusion process of generation, will certainly with serving bad phenomenon.So sum up in process of production, more recurrent bad as follows:
The printing caused due to the foreign matter of glass baseplate surface is bad;
Due to glass baseplate surface foreign matter and high strength extruding, the glass substrate breakage caused, or galley is wounded by stabbing, and A wheel is stabbed even;
Due to the foreign matter on printing platform, glass substrate is caused to adsorb bad;
Due to the foreign matter on printing platform, the glass substrate caused when printing is crushed.
So far, industry professional person has dropped into a large amount of manpower and materials extremely at corresponding this type of, though there are some effects, does not also get a desired effect, does not fundamentally solve problems.
