The invention relates to an automatic insert placing machine. The automatic insert placing machine comprises a machine frame, an electronic control device, a workbench, a feeding vibration disc, a misalignment mechanism, an insert positioning and bearing device, a three-coordinate device, a clamping head, and an operating panel. The automatic insert placing machine is simple and convenient to operate, during using, the electronic control device controls the feeding vibration disc to send the insets to the misalignment mechanism through the operating panel, a Y-axis moving track, a Z-axis moving track and the clamping head are driven to move to the misalignment mechanism through the an X-axis driving motor, a Y-axis driving motor, a Z-axis driving motor respectively, the inserts are clampedthrough the clamping head, then the inserts are moved to the insert positioning and bearing device to be arrayed and placed neatly, the inserts are conveniently, fast and accurately placed in a moldthrough a follow-up burying robot, in this way, the inserts of the many different types can be automatically, neatly, and accurately placed, and the purpose of the effective improving of the work efficiency of loading the inserts into the mold is achieved accordingly.
