    摘要： Disclosed herein are a production apparatus of a motor laminated core and a method for producing the same, the production apparatus comprises an upper die assembly, a lower die assembly and an adhesive spraying device, the adhesive spraying device comprises an adhesive spraying plate, a first die plate and a second die plate successively from top to bottom, and channels are disposed between the plates, and respective channels communicate with first adhesive spraying openings and second adhesive spraying openings so as to coat an adhesive on a portion of a metal strip used for forming an core sheet, and after the core sheet is formed, a plurality of core sheets are cured and bonded at normal temperature in the production apparatus with the aid of a hydraulic cylinder so as to form a motor laminated core. In addition, quantitative adhesive spraying can be achieved by setting parameters of an adhesive spraying control device. Since the channels are disposed on the die plates, there is no need to dispose adhesive pipelines, so that adhesive input pipelines are reduced, a corresponding faulty pipeline can be quickly found during use, which improves troubleshooting speed, facilitates cleaning, and avoids frequent replacement of vulnerable parts.
