The invention provides an automatic core-setting robot and an automatic core-setting method. The automatic core-setting robot includes a linear transmission device, a gantry truss and a transfer robot. The transfer robot includes an X-axis moving mechanism, a Y-axis moving mechanism, a Z-axis moving mechanism and a rotating mechanism. It also includes a supporting jig combination composed of a floating plate, a sand core mold, a fixture support frame, a sand core jig and a second quick-connecting mounting bracket. The positioning structure between the matching jig combinations can ensure that the sand core jig quickly Stable installation and replacement; when setting the core, you only need to hoist the sand core from the sand core warehouse to the sand core mold, and the linear transmission device and transfer robot will automatically complete the core setting operation, which greatly improves the production efficiency; The installation position in the lower mold of the casting molding is precise, ensuring reliable and stable casting quality.
