1. A workpiece orientation mechanism comprising:
a driving device including a transmission motor and a controller which are connected with each other via signal, the transmission motor defining an axial direction;
a rotating seat, combined with the transmission motor, and capable of being driven to rotate by the transmission motor;
an orientation head disposed on the rotating seat to rotate synchronously with the rotating seat, wherein the orientation head is capable of moving along the axial direction relative to the rotating seat, one end of the orientation head includes a mounting head, and a blocking member is disposed on the orientation head;
reset means, arranged between the rotating seat and the orientation head, and positioning the orientation head at a predetermined position; and
a sensor facing the blocking member, wherein the sensor is signally connected with the controller;
wherein the transmission motor includes a rotating shaft;
the rotating seat includes a penetrating hole, the rotating shaft is inserted through and locked in the penetrating hole, the rotating seat includes an elastic member fixing portion, the reset means is an elastic member, and one end of the elastic member is fixed to the elastic member fixing portion;
the orientation head includes a locking portion, a blocking member coupling portion, and an elastic member receiving portion, the locking portion is a columnar body and extends along the axial direction, two ends of the locking portion along the axial direction are respectively a first end and a second end, the first end is provided with the mounting head, the elastic member receiving portion is located at the second end, another end of the elastic member is fixed to the elastic member receiving portion, the blocking member is disposed on the blocking-member inductor coupling portion;
the sensor includes a sensing unit that faces the blocking member, and the sensing unit is signally connected to the controller;
wherein, when a workpiece abuts the mounting head to move the orientation head and the blocking member along the axial direction, the sensor transmits a driving signal to the controller to drive the transmission motor, and the transmission motor drives the rotating seat, the orientation head, and the blocking member to rotate by a rotation angle, so that the mounting head engages the workpiece, meanwhile, the reset means causes the orientation head and the blocking member to return along the axial direction, and makes the sensor send the driving signal to the controller to stop the transmission motor, and the transmission motor sends a feedback parameter to the controller to obtain the rotation angle, and the controller calculates a compensation angle based on the rotation angle and a predetermined angle, and then drives the transmission motor to rotate by the compensation angle.
