[0034] The automatic feeding mechanism of the utility model is used to automatically feed materials. This time, the automatic operation of a lathe is used as an example to explain in detail. The working principle is as follows:

[0035] First, the connecting mobile conveyor line moves to the outside to wait for the material to be received. Its roller conveyor line is forwarded to the material. Its stepper motor drives its synchronous belt to make its roller conveyor line run to the corresponding position on the slide rail, and then its roller conveyor line reverses to allow the material to enter the mobile working platform. Then the mobile working platform of the three-dimensional manipulator feeding system moves to the right, and its roller conveyor line reverses to receive the material sent by the connecting mobile conveyor line. After the material arrives at the mobile working platform, it moves to the left. After it is in place, the stepper motor in the XYZ axis ball screw slide of the three-dimensional manipulator drives the ball screw to move, and cooperates with the rotating cylinder and the cylinder clamp to clamp the material to the workpiece positioning seat in the multi-functional feeding mechanism. The first cylinder cooperates with the second cylinder to deliver the material to the machine tool, and waits for the material to be retrieved after the processing is completed. Finally, go through the process again in reverse to complete the processing cycle. When the roller conveyor line connected to the mobile conveyor line rotates forward and receives the material, its stepper motor drives its synchronous belt to reverse and deliver the material to the receiving position of the warehouse storage system.

[0036] The stepper motor of the warehouse storage system drives the ball screw to reverse and make the roller conveyor line run to the receiving position. The drive motor of the material blocking mechanism reverses and retracts the baffle, waiting for the connecting mobile conveyor line to transport the processed materials to the receiving position. The DC motor of the roller conveyor line reverses to receive the materials. After the warehouse storage system receives the materials, its stepper motor drives the ball screw to rotate forward and runs under the baffle. The drive motor rotates forward and the baffle extends to drag the material tray. Finally, the stepper motor of the warehouse storage system drives the ball screw to reverse and return to the receiving position, waiting for the next material to be received.

Although the present invention has been disclosed as a preferred implementation case as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to the equivalent implementation cases of equivalent changes by using the structure and technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above implementation cases based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
