The invention discloses automatic loading and film expanding equipment for wafer discs. The automatic loading and film expanding equipment for the wafer discs comprises a wafer disc lifting basket device, a lifting basket lifting platform mechanism, a clamping jaw movement mechanism, a wafer clamping jaw mechanism, a wafer mold expanding workbench and an XY-axis linear module. According to the invention, rapid and mass production for blue wafer film discs in a production process for semiconductor devices can be achieved, a manual operation mode is replaced, high efficiency, high quality and stable performance are achieved, middle film expanding machine equipment is reduced, manual operation and production management costs are reduced, unstable quality caused by the fact that product quality changes along with human factors is avoided, meanwhile, production operation is convenient and rapid, wafer products are convenient to store and use, environment protection for the wafer products is facilitated, quality problems such as wafer smudginess are effectively solved, and high production efficiency and stable product quality are achieved.
