Reflow daily maintenance content: (1) Check whether there is grease in the transmission chain, and add grease in time if necessary. (2) Check that there is no running edge in the transport network, and notify HB in time if there is running edge. (3) Check the reflow furnace inlet mesh belt drive wheel is not shifted, if there is a shift can be adjusted by loosening the screw - adjusting - locking the screw step. (4) Check whether the net belt drive roller at the outlet of reflow furnace is loose, if it is loose, it can be adjusted according to the steps of loosening the screws - adjusting - locking screws. (5) Check whether the high temperature oil in the oil cup is appropriate, the oil surface should be 5mm from the mouth of the cup, if necessary, add high temperature oil in time.
Reflow maintenance content: (1) Check the surface of the transport network belt for dirt adhesion, if there is loot adhesion in time with alcohol scrub. (2) Check the guide rail chain groove for foreign bodies, if there are foreign bodies in time to remove the chain with alcohol scrub. (3) Check whether the bearings of the driven gear of the transport chain are flexible, and add lubricating oil in time when necessary. (5) Check whether there is grease on the surface of the lead rod of the head component and no foreign matter, wipe it clean in time when necessary, and add grease. (6) Check whether there is FLUX and dust on the rectifier plate in each area of the furnace, and clean it with alcohol in time if there is dust. (7) Check whether the lifting motor of the furnace lifting system is running without vibration and noise, if there is vibration or noise, it should be replaced in time (8) Check whether the filter of the exhaust device is blocked, if there is blockage, alcohol should be used to clean. (9) Check whether there is FLUX adsorption on the rectifier plate in the cooling area of the cooling system. If there is FLUX, it should be cleaned with alcohol in time. (10) Check that the surface of the photoelectric switch at the transport entrance has dust-free accumulation. If there is dust accumulation, it should be wiped clean with a soft dry rag in time. (11) Check whether the surface of the PC and UPS is clean. If there is dust accumulation, it should be wiped with a soft dry cloth in time.
Monthly maintenance contents of reflow welding: (1) Check whether there is vibration and noise in the transportation process, and notify HB in time if necessary. (2) Check whether the transport motor fixing screw is loose, if it is loose, lock the screw. (3) Check whether the tension of the transmission chain is appropriate, and adjust the motor positioning screw in time if necessary. (4) Check whether there is coke and black powder on the transport chain, if there is, it should be removed in time and cleaned with diesel oil. (5) Check the positioning of the synchronous shaft of the width adjustment in the track of the active end, and whether the fixed block is loose. If it is loose, it should be locked in time. (6) Check whether the hot air motor positioning screw is loose, if loose, it should be locked in time. (7) Check whether there is dust and foreign matter in the control box of the electrical system. If there is foreign matter, blow out dust and foreign matter with the same pressure air after power off.
