Abstract
The invention relates to a device and a method for cleaning a missing forme, which is suitable for a printing procedure of manufacturing a plasma display screen. In order to solve the problem of pollution of the missing forme, the device for cleaning the missing forme comprises a cleaning roller, a mechanism for driving and adjusting the cleaning roller, a release roller, a reclaiming roller, a drive motor for driving the reclaiming roller, a viscous belt and a force balancing mechanism; the viscous belt is wound on the release roller, starts from the release roller, rounds the cleaning roller and is finally connected with the reclaiming roller; the mechanism for driving and adjusting the cleaning roller can drive and adjust the cleaning roller so that the cleaning roller drives the viscous belt to be continuously stuck on the lower surface of the missing forme; and the force balancing mechanism on the upper surface of the missing forme and the viscous belt advance together to provide equilibrant for the viscous belt, that is in the advancing process, dirt on the missing forme is stuck on the viscous belt; and the reclaiming roller is driven by the drive motor so as to reclaim the viscous belt stuck with the dirt, thereby realizing continuous and effective cleaning.
Description
Technical field
The present invention relates to clean the apparatus and method of through printing forme, particularly, relate to the apparatus and method that in the printing process of making plasma panel (PDP screen), through printing forme cleaned.The invention still further relates to the printing machine that comprises this device.
Background technology
In current PDP main flow manufacturing technology, the most structures in forward and backward two substrates are completed by serigraphy, and the quality of printing is the key factor that influences properties of product.So, in PDP manufacturing process, the requirement of cleanliness factor is not less than 1000 grades.
Yet, in screen printing process, often causing impurity such as through printing forme adsorbing fiber, hair owing to reasons such as static, it is bad that product takes place.
Moreover when printing fluorescent material, fluorescent powder paste material can be residual on the through printing forme space of a whole page.The untimely cleaning of residual slurry can be printed onto the barrier top and should not print in the barrier groove of this kind fluorescent material.Cause colour mixture, influence product quality.
Also have, what occur in the printing also can form not due trace from phenomenons such as net are bad on substrate surface, and this kind trace needs elimination immediately, otherwise can influence the bulk article quality.
At the problems referred to above, the various methods that are used to clean through printing forme have appearred in the prior art.Up to the present, mainly contain solvent clean method, air blow off method, wipe method and transfer printing etc.
Publication number is that CN1252351A, denomination of invention disclose a kind of solvent clean method for the patent documentation of " method and apparatus that is used for the cleaning silk screen of screen process press ".The cleaning effect of solvent clean method is better, but can influence printing quality because of dissolvent residual, and device is complicated, easily produces and pollutes.
To be CN1219908A, denomination of invention disclose a kind of air method of blowing off for the patent documentation of " cleaning device and clean method " to publication number.The air method of blowing off is simpler than solvent clean method, but for the residual slurry of sclerosis easy-clear not, and noise is big in the reset procedure, causes slurry to splash easily and forms pollution.
What adopt in the patent documentation that patent publication No. is CN1141239, denomination of invention for " in the screen printing used web plate cleaning device " is that scraper plate is wiped or in conjunction with moistening cleansing tissue method for deleting.Wipe the device structure complexity of method, and easily through printing forme is caused damage.
Transfer printing is by repeatedly dropping into the printing of non-product glass substrate, the cleaning that the foreign matter transfer printing on the through printing forme is carried out on glass substrate.Its shortcoming is the waste slurry, and cleaning time is long, and foreign matter is not easy to clean clean.
Summary of the invention
For solving the through printing forme pollution problems, the present invention proposes to clean the apparatus and method of through printing forme, this apparatus and method can be easy and continuous effective ground remove dirts such as impurity, foreign matter or residual slurry on the through printing forme, also do not have the defective that various clean method brought in the prior art.The present invention also provides a kind of screen process press that comprises this Clean-device.
According to an aspect of the present invention, a kind of device that cleans through printing forme is provided, this device comprises clearer, be used to drive and adjust the mechanism of clearer, discharge roller, reclaim roller, be used to drive the drive motors that reclaims roller, adhesive tape and dynamic balance mechanism, described adhesive tape twines on described release roller and walks around described clearer and finally be connected on the described recovery roller from described release roller, the described mechanism that is used to drive and adjust clearer can drive and adjust described clearer makes it drive the lower surface that adhesive tape is pasted described through printing forme continuously, described dynamic balance mechanism advances with described adhesive tape and such equilibrant force is provided for described adhesive tape at the upper surface of described through printing forme, promptly in the traveling process dirt on the described through printing forme is adhered on the described adhesive tape, described recovery roller reclaims the adhesive tape that adhesion has dirt by described drive motors driving together.
According to a further aspect in the invention, provide a kind of screen process press, this screen process press comprises said apparatus.
Preferably, describedly be used to drive and adjust the mechanism of clearer and described clearer is installed in described screen process press below described through printing forme body, described release roller, described recovery roller and be used to drive the body that the drive motors that reclaims roller is installed in the rear side of described screen process press.
In accordance with a further aspect of the present invention, a kind of method that cleans through printing forme comprises the steps:
The mechanism that adjusts and drive clearer drives clearer, makes described clearer arrive the end of described through printing forme, in this process, discharges roller and discharges adhesive tape, makes described adhesive tape arrive the end of described through printing forme with described clearer;
The mechanism that adjusts and drive clearer adjusts described clearer, makes the adhesive tape that is driven by described clearer paste the lower surface of described through printing forme;
Dynamic balance mechanism provides such equilibrant force for described adhesive tape in the position that described adhesive tape is pasted from the upper surface of described through printing forme, even the dirt on the described through printing forme can adhere on the described adhesive tape;
The mechanism of described adjustment and driving clearer drives described clearer, make described clearer drive the lower surface that described adhesive tape is pasted described through printing forme continuously, in whole process, described dynamic balance mechanism provides described equilibrant force ground to advance continuously with described adhesive tape, meanwhile, described recovery roller is driven by drive motors, thereby reclaims the adhesive tape that adhesion has dirt.
This shows that the present invention compared with prior art, and is simple in structure, easy to use, and can effectively clean through printing forme continuously, rapidly.And, with an organic solvent do not help the raising of press quality.Directly do not contact, avoided damage barrier with barrier.Cleaning function is realized automation, increases work efficiency.Eliminate the pollution that when manually cleaning through printing forme product is caused, further improved yields.
