The stamping robotic arm manipulator is a device developed on the basis of automation equipment and specially developed for the unmanned production of stamping automation according to the characteristics of stamping products. It can replace the man power in terms of stamping, handling, loading and unloading of materials in various stamping stations. The robotic arm manipulator has an important embodiment in saving manpower and labor costs, improving labor and equipment safety, and maintaining product productivity, quality and process stability in the industries of repetitive, dangerous and high-beat product manufacturing. With the development of the stamping automation industry, various arm manipulator have been designed according to different product processes and on-site use environments. Among them, the most common and most used stamping robots are: connecting rod manipulator, in-mold manipulator, independent manipulator, two-dimensional manipulator, three-dimensional manipulator and so on.
