The invention relates to an automatic footwear 
production line with a saved use space. The automatic footwear 
production line comprises an automatic upper 
sizing device and an automatic sole 
sizing device which are arranged up and down in an abutted manner, wherein the automatic upper 
sizing device comprises a first conveying belt, a first driving 
assembly and a first automated glue spraying control 
assembly, the first automated glue spraying control 
assembly comprises a three-dimensional scanning mechanism, a first treating water baking mechanism, a first glue baking mechanism and first multi-
station hoisting 
manipulator equipment, the first multi-
station hoisting 
manipulator equipment comprises a controller, a first 
manipulator with 
six degrees of freedom, a first 
lateral movement control mechanism, a first spray lance and a second spray lance, and the first 
lateral movement control mechanism comprises a first fixing frame, a first guiding assembly, a first mobile table and a first transmission assembly. According to the automatic footwear 
production line with the saved use space, the volume of glue sprayed to each part of an upper can tend to consistency, the wastage of the glueis greatly lowered, the consistency of glue spraying effect of the upper is improved, then, the degree of firmness of subsequent bonding between uppers and soles is increased, service lives of footwear are prolonged, and the quality of the footwear is improved.
