[0006] Furthermore, pneumatic modules are fixedly connected to the four corners of the connecting platform, and clamping claws are provided at the ends of the pneumatic modules. The clamping claws are distributed in a four-corner pattern and matched with the four corners of the workpiece.

[0011] Compared with the above-mentioned background technology, the automatic clamping robot for injection molding machines provided in this application includes a robotic arm with very mature technology today, and a clamping mechanism and a positioning mechanism as core components. Its principle relies on clamping the workpiece through multiple claws, and then placing the workpiece on the inspection table for inspection through the transfer of the robotic arm. At the same time, when clamping the workpiece, the position of the workpiece is first limited and fixed by the positioning mechanism.
