Coating system related in the described coating process also can comprise Programmable Logic Controller (PLC) and/or drying unit simultaneously.
The signal input part of described Programmable Logic Controller (PLC) links to each other with the speed probe that coating is carried on the back among the Kun, gather the linear velocity of coating back of the body Kun, its signal output part links to each other with the measuring pump of controllable flow amount, the adhesive output quantity instruction that calculates is delivered to the measuring pump of adjustable throttle amount.
Described drying unit is generally tunnel drier, protective cover is located preferably to be provided with directly over being positioned at base material in the outside of drying unit, on the one hand can reduce the solvent that evaporates from substrate surface and enter the environment, also play the effect on the base material that the dust that prevents in the environment or other solid impurities fall coated adhesive on the other hand with coated adhesive.
Related various device is the conventional equipment of this area among the present invention.
Utilize method coating solar cell module back veneer of the present invention, the range of flow of charging pump generally is controlled at 500-1200ml/min, and the error of control accuracy is less than 0.5%.Tu Bu adhesive phase thickness and precision error is less than 0.5 micron in this way.
Beneficial effect of the present invention:
The present invention adopts the mode of quantitative no feed back, and the quantitative feed by through metering is transported to the coating cavity by sealing pipeline, guarantees that adhesive is coated on the base material fully uniformly.Native system does not have the circulation and the material trough that opens wide of material, and the material viscosity equilibrium is remained unchanged, and makes the material of coating even, and the whole uniformity in the compound back of film improves, and has improved product quality.Owing to do not adopt unlimited hopper, reduce the solvent evaporates amount in the applying material significantly simultaneously, do not caused environmental pollution, more helped environmental protection.By adopting the PLC control system can adjust the material output quantity automatically, play the real-time monitoring of system and the effect of adjustment, production operation is more simplified, can carry out industrial continuous production easily.
