Description
Technical field
The present invention is a kind of air curtain crystallization prevention device and air curtain crystallization-preventive method of TFT-LCD colored filter rework equipments, belongs to flat panel Liquid Crystal display technique field.
Background technology
In the production run of TFT-LCD colored filter rework equipments, this equipment is peeled off between (one), stripping (two) unit and the effect of the twice air curtain peeled off between (two), washing unit is: purge clean by the stripping alkali lye on the glass passed through, make alkali lye not flow into next unit.But upper air curtain is very easy to crystallization and blocks, the alkali lye that causes glass to accumulate above purges clean, so need frequent shutdown to clear up upper air curtain, it is bad that upper air curtain purges effect, also causes alkali lye excessive loss to waste, and wastewater treatment difficulty and expense.
In production run, because process conditions are 65 DEG C, moisture meeting loss in alkali lye, concentration likely changes, so need to keep the skin wet.In order to the moisture of supplementary stripping alkali lye loss, the pipeline being peeled off unit bottom by A stripping, B is that two unit supplement ultrapure water SPW.
When A stripping, the B upper air curtain peeled off between unit are blocked by alkali crystalline solid, stripping alkali lye above glass just can not purge clean by the CDA of air curtain blowout, cause alkali lye above glass to flow into B with stripping and peel off unit, after B peels off the stripping alkali lye backflow in unit, liquid level just rises and overflow, is discharged into waste lye accumulator tank by discharge tube; When air curtain when between B stripping, washing unit is blocked by alkali crystalline solid, air curtain also can blow the stripping alkali lye that clean glass accumulates above, causes peeling off alkali lye inflow and washes unit with discharge of wastewater to waste water collection tank.
Summary of the invention
What the present invention proposed is a kind of air curtain crystallization prevention device and crystallization-preventive method of TFT-LCD colored filter rework equipments, and its object is intended to solve the upper air curtain problem of alkali lye blocking to ensure that equipment runs well; Reach the moisture supplementing loss in production and the effect reducing alkali lye loss and waste; Interval time and the frequency of air curtain in maintaining can also be extended; Reduce wastewater treatment difficulty and expense.
Technical solution of the present invention: the air curtain crystallization prevention device of TFT-LCD colored filter rework equipments, it is characterized in that comprising air curtain, pipeline, CDA hand valve, SPW solenoid valve, SPW hand valve, wherein go up air curtain connecting tube, the A end of described pipeline connects upper air curtain, the B end of pipeline connects with one end of SPW solenoid valve, one end of another termination SPW hand valve of SPW solenoid valve, another termination ultrapure water of SPW hand valve; During work, first adjust SPW hand valve and control tap water flow and pressure, then control water inlet by the timing switching electricity of SPW solenoid valve and do not intake; During water inlet, upper air curtain sprays gasified water, rinses or melt the stripping alkali lye of upper air curtain mouth end crystallization.
Upper air curtain crystallization-preventive method, first adjusts SPW hand valve and controls tap water flow and pressure, then control water inlet by the timing switching electricity of SPW solenoid valve and do not intake; During water inlet, upper air curtain sprays gasified water, rinses or melt the stripping alkali lye of upper air curtain mouth end crystallization.
Advantage of the present invention: (1) improvement cost is less; (2) reforming technology is simple, processing ease; (3) prevent crystallization effect good, the extension device working time, decrease downtime and the maintaining frequency, decrease workload; (4) the pipeline reconfiguration of the ultrapure water SPW that will supplement for stripping unit (), (two), to upper air curtain, is kept the skin wet by vaporize water, can supplement the moisture lost in production, can rinse air curtain again, prevent blocking, the effect of air curtain in guarantee; (5) reduce loss and the waste of alkali lye, decrease treatment capacity and the expense of waste lye; (6) because stripper belongs to highly basic, also reduce the potential safety hazard that highly basic is hurted sb.'s feelings, ensure that personal security.
Accompanying drawing explanation
Fig. 1 is the air curtain structure schematic diagram of existing TFT-LCD colored filter rework equipments.
Fig. 2 is the structural representation of the air curtain crystallization prevention device of TFT-LCD colored filter rework equipments.
In figure 1 is air curtain, 2 are pipelines, 3 are CDA hand valves, 4 are SPW solenoid valves, 5 is SPW hand valves.
Embodiment
As shown in Figure 2, the air curtain crystallization prevention device of TFT-LCD colored filter rework equipments, its structure increases a threeway at pipeline 2 place, a termination pressurized air, other end reconfiguration ultrapure water---by the ultrapure water SPW pipeline reconfiguration peeling off unit for A, B stripping unit supplements.Its Central Plains compressed air piping system is constant, ultrapure water pipeline is installed in addition with ultrapure water SPW solenoid valve 4 and SPW hand valve 5.During work, first adjust SPW hand valve 5 and control tap water flow and pressure, then control water inlet by the timing switching electricity of SPW solenoid valve 4 and do not intake; During water inlet, upper air curtain sprays gasified water, rinses or melt the stripping alkali lye of upper air curtain mouth end crystallization.
