The invention discloses an automobile 
disc brake spraying 
production line and a production method thereof, and the automobile 
disc brake spraying 
production line comprises: an automatic 
coating unit for spraying a to-be-processed automobile 
disc brake part; a high-temperature curing oven is used for carrying out 
coating curing on the automobile disc 
brake part subjected to the spraying step in a controllable distributed heating mode; a cooling device that is used for cooling the automobile disc 
brake part subjected to paint particle curing; and a main conveying belt that is used for conveyingthe automobile disc 
brake part to be processed and is arranged at the high-temperature curing oven and the cooling device. The automatic 
coating unit is 
integrally closed, so that leakage of paint 
powder is avoided, and 
static electricity is prevented from hurting an operator; a matched device for paint 
powder recycling is arranged, redundant paint 
powder is recycled, materials are saved, the overall working process is accelerated through high-temperature curing oven 
assembly line heating, the 
automation efficiency is improved, and errors caused by manual operation are reduced; subsequent aircooling can accelerate cooling of the parts, the parts can be conveniently taken down from the conveying belt, meanwhile, recovered heat can be used for other purposes, and energy is saved on the whole.
