2. along with the rotation of the turntable 2, the rotor to be processed moves to the next riveting station, the rotor to be processed is riveted, the upper ejector block motor 41 drives the upper ejector block screw rod 42 to act downwards, and the riveting motor 45 drives the riveting screw rod 46 to act upwards; then, the riveting upper ejection block 44 is pushed to downwards press the upper part of the workpiece to be machined, and the riveting head 47 upwards acts on the rivet in the workpiece to be machined, so that the rivet head is turned outwards to deform; after the riveting is finished, the upper ejector block motor 41 and the riveting motor 45 drive the upper ejector block screw rod 42 and the riveting screw rod 46 to move reversely, so that the riveting upper ejector block 44 and the riveting head 47 return to the original positions, and the workpiece to be riveted is transferred to the next station along with the turntable 2;
3. the riveted rotor moves to the next laser engraving station along with the turntable 2, laser code engraving and top loosening operations are carried out on the riveted rotor, firstly, laser heads 51 carry out laser etching on the upper part of the rotor, so that each rotor finished product has a unique code which can be used for subsequent statistics and identification; then, the top loosening motor 54 is started to drive the top loosening rod 53 to move upwards, push the ejector rod 56 to move upwards, and after the ejector rod contacts the upper rotor, the top loosening is carried out;
4. the rotor enters the last detection station along with the rotation of the turntable 2, the ejection cylinder 68 starts to work, and the ejector rod 67 is pushed upwards to move upwards to eject the rotor to a specified height; then the lifting cylinder 66 is started to adjust the clamping jaw 61 positioned right above the rotor to a proper height along the lifting table 661; then the clamping cylinder 62 is started, after the clamping jaw 61 grasps the workpiece, the lifting cylinder 66 is started again and pushes the clamping jaw 61 upwards along the lifting table 661 to a specified height; then, a steering motor 65 is started, the clamping jaw 63 is horizontally and clockwise moved to a specified angle, and the rotor is placed right below the detection camera; the camera firstly checks the laser engraving seal code above, checks the engraving quality and records; then, the rotary cylinder 63 is started, the whole rotor is rotated by 180 degrees up and down, and the quality of riveting below the rotor is detected by a detection camera and recorded; if the workpiece is checked to be correct, the rotary cylinder 63 rotates the workpiece up and down by 180 degrees again, and the steering motor 65 is started again to horizontally move the rotor to a specified angle; the lift cylinder 66 is then actuated to lower the rotor to the desired height, the clamp cylinder 62 is then actuated to release the rotor for placement at the pre-prepared product placement, the robot gripper returns to the home position, and the commutation process ends.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
