Automatic feeding and discharging machining system

An automatic loading and unloading processing system, comprising:

• a material storage assembly;
• a transport mechanism;
• and a positioning device, wherein
• the material storage assembly is used to store workpieces;
• the transport mechanism is used to transport the workpieces between the material storage assembly and the positioning device;
• the material storage assembly includes:
• a material tray;
• a plurality of fixing bases;
• a motion mechanism;
• and a plurality of holders for fixing the workpieces, and the holders are fixed on the fixing bases, and the motion mechanism rotates the material tray to move one of holders to correspond to the transport mechanism;
• the transport mechanism includes:
• an auxiliary loading and unloading system arranged at a worktable to grab the one of the holders on the material tray and to move the one of holders horizontally and;
• a main loading and unloading system arranged on a main spindle ram to grab the one of the holders grabbed by the auxiliary loading and unloading system and to move the one of the holders vertically;
• and,
• wherein the positioning device is arranged on the worktable to fix the holders grabbed by the main loading and unloading system.
