The main function of the wave soldering machine spray system is to spray the rosin flux evenly on the printed circuit board. The wave soldering spray system is composed of rod cylinder, nozzle, photoelectric switch, proximity switch, solenoid valve, oil and water separator.
Maintenance instructions for the wave soldering spray system.
1. Pay attention to the discharge of water in the oil-water separator every shift, from the bottom up the oil-water separator drain valve, the water will be discharged naturally.
2. The nozzle is a precision component, its spool and nozzle clearance manufacturing precision is very high, so as to achieve super atomization effect and sealing, in use to pay attention to cleaning the nozzle from time to time, trace of impurities in the pine perfume or volatile residues will block the nozzle, affecting the atomization effect, so every 8 hours to clean times.
3. The oil and water separator should often be removed and cleaned with industrial ethanol to ensure that the air is clean and does not pollute the flux.
4. It is recommended to use no-clean flux, avoid using sticky flux, pay special attention to avoid using very acidic flux, so as not to cause corrosion of nozzles, fittings and other components. each shift must be cleaned to the second nozzle, in order to prevent the nozzle blockage, affecting production.
5. Frequently scrub the light bar of the spraying device with sprinkling essence, and grease it.
6. The origin of the proximity switch (remote proximity switch), photoelectric switch should often observe whether there is debris, generally should be removed once a month for cleaning. Cleaning, should pay attention to the use of wet soft rags gently wipe off large wave soldering spray device debris.
Wave soldering spray system daily operation and maintenance.
1. Because of the volatility of various ingredients in the flux is not the same, so the production must often check the specific gravity of the flux, so that the amount of flux to maintain a good specific gravity: 0.80 ~ 0.83 (to flux manufacturer requirements shall prevail).
2. Often check the sprinkling essence and flux is in line with the process requirements.
① Weekly regular removal of the nozzle with sprinkler cleaning, and then in the nozzle spring and seal ring grease.
② Discharge the accumulated water in the air filter in time.
③ Check regularly for broken air tubes.
Wave soldering spray system precautions.
1. Flux and solvent are flammable, fire and smoke should be strictly prohibited and fire extinguishing equipment should be installed near the machine.
2. Avoid direct skin contact with flux, and use flux strictly in accordance with the relevant matters provided by the flux supplier.
3. During normal working hours, the machine will produce smoke and harmful gases, a good fume extraction system should be installed and avoid opening the glass window and the sliding door behind the machine.
