Special wave soldering maintenance for lead-free tin bars

The mechanical part of the wave soldering furnace dedicated to lead-free tin bars: If the machine is running for too long without maintenance, the spot inspection will show that the screws are loose, the density of the gear teeth is not good, the chain speed slows down, and the transmission shaft may be rusted Deformation of the track (such as bell mouth, trapezoidal shape, etc.), lead-free tin bar will lead to falling boards, board jamming, poor quality after the furnace, and horizontal deformation of the track. It not only affects the performance of the machine itself but also wastes production time. Note: In high temperature, the guide rail is easy to lose oil, which will cause the chain to be stuck. It needs to be refueled regularly (300 degrees high temperature grease). , it needs to be replaced. If it works in a worn state for a long time, it will damage the bushing, motor or frequency converter. Spray part of wave soldering furnace: If the spray system is not maintained for a long time, the photoelectric sensor will fail, the PLC program control will be inaccurate, the identification data of the encoder synchronized with the track motor spray motor will be inaccurate, and the speed of the spray motor will slow down, etc. Fault. This failure will affect the phenomenon of uneven flux spray (uneven amount, spraying may be advanced or delayed), nozzle clogging, insufficient pressure, reduced flow rate, and increased moisture in lead-free solder flux. It not only affects the quality of the furnace but also increases the maintenance personnel behind the furnace. How to control the cost, how to prolong the service life of the machinery, and how to talk about the utilization rate are worth pondering. Note: The spray system needs to pay attention to the corrosion of the air pipe in the flux, which needs to be replaced regularly. The stepping system should pay attention to the flux residue in the motor, which will cause a short circuit and fire. Blocking.
