Maintenance of wave soldering machine is mainly divided into: cleaning the tin tank, cleaning the control box, frequently checking the composition of the tin, frequently checking the tension of the chain, frequently checking the claws of the chain, frequently making an overall inventory of the equipment, and frequently refueling the pump and bearings. No maintenance will cause harm to the mechanical part of the wave soldering and electrical part of the harm.
I. The wave soldering mechanical part of the harm caused by the lack of maintenance
If the wave soldering machine running time is too long, there will be screws loose, gear teeth and wheel density and degree is not good, the chain speed slows down, the drive shaft may be rust caused by deformation of the track, which will lead to drop plate, cardboard phenomenon, the appearance of the furnace after the quality of the poor, the track level of deformation and other conditions.
Heat pipe part
If the use of time is too long without maintenance and replacement of the heat pipe, there will be uneven heating temperature of the heat pipe, heat pipe aging, fracture. If there is cold welding, tin beads, short and other bad, DIP wave soldering will affect the role of flux on the PCBA.
Tin tank of solder melting time is extended due to uneven temperatures leading to burst tin, temperature control that is inaccurate and so on. This is neither quality assurance and waste of production time, and will increase the cost of machinery, labor costs and material costs.
II. The wave soldering machine electro-pneumatic part of the harm caused by the lack of maintenance
If the wave soldering machine is too long without maintenance, overhaul or replacement of some parts, it will lead to increased insulation resistance of the wire, so that the conductivity is not strong, poor contact in the energized will pull the light, short-circuit, at this time, the current in the circuit will be doubled, and may burn the electrical components and instrumentation.
Spray part
If a long time production does not spray system maintenance will lead to photoelectric sensing failure, PLC program control is inaccurate, synchronized with the orbit motor spray motor recognition code reader identification data is not accurate, spray motor speed slowdown and other failures.
This failure will affect the flux spray uneven, clogged nozzles, pressure is not enough, the flow rate is reduced, flux moisture increases and other phenomena. Not only affect the quality of the furnace after the increase in furnace maintenance personnel.
