The invention discloses an automobile door panel production 
system and a production process thereof, belongs to the technical field of automobile part 
assembly, and solves the problems that an automobile door panel production 
system in the prior art is relatively limited in function, operation information cannot be recorded in the production process, 
verification between procedures cannot be carried out, and the expandability is insufficient. The automobile door panel production 
system takes 
modular design as a principle, comprises an incoming material 
management system, a production 
management system, an error-proofing 
control system and a tracing system, is clear in production process path, sets a necessary step of judging whether each 
station is provided with a necessary step or not, ensures that parts with wrong configuration do not flow into the next process. Mistake proofing between procedures, mistake proofing between the procedures and production equipment of the procedures and mistake proofing of secondary 
verification of the parts are provided, secondary 
verification of the parts is used for verifying the two-dimensional codes of the current parts and the two-dimensional codes required by a production plan, and the functions of secondary verification and code scanning of the easily-mixed parts, information verification between the procedures and information verification between the procedures and the procedure equipment are achieved; and therefore, the product quality is ensured.
