The automatic marking device for chucks according to claim 2, characterized in that: The material return mechanism includes a drive motor, a gear transmission mechanism connected to the output shaft of the drive motor, a sprocket transmission mechanism connected to the gear transmission mechanism, and a material unloading mechanism connected to one side of the marking slide. The sprocket transmission mechanism is vertically installed on one side of the base frame, and the gear transmission mechanism is horizontally installed on the base frame. The outer ring of the sprocket drive mechanism is provided with evenly distributed receiving trays. The receiving trays are adapted to receive the clamps that slide down from the opening of the marking slide. The receiving trays are horizontally connected to the sprocket drive mechanism through a spring frame. The unloading mechanism includes a vertical connecting frame, a flexible dial frame, and a slide groove. The bottom end of the vertical connecting frame is connected to the opposite side of the marking slide groove relative to the opening. The top end of the vertical connecting frame is connected to both the flexible dial frame and the slide groove, with the flexible dial frame positioned above the slide groove. As the receiving tray moves upward through the sprocket transmission mechanism, the elastic pressing of the elastic dial frame tilts the clamp in the receiving tray into the slide groove, and the clamp slides into the rotating disk through the slide groove.

4. The automatic marking device for chucks according to claim 3, characterized in that: The gear transmission mechanism includes a first drive gear connected to the output shaft of the drive motor, an intermediate gear transmission mechanism horizontally mounted on the base frame, and a support gear mounted on the bottom plate of the base frame. The intermediate gear transmission mechanism includes an intermediate shaft horizontally passing through the base frame. A first driven gear that meshes with the first driven gear is installed at one end of the intermediate shaft near the first driving gear. A second driven gear and a third driven gear are also installed on the intermediate shaft. The second driven gear meshes with the support gear, and the second driven gear and the third driven gear are located on opposite sides of the base frame.

5. The automatic marking device for chucks according to claim 4, characterized in that: The sprocket drive mechanism includes a first sprocket mounted on the intermediate shaft, a second sprocket mounted on the top side of the base frame via a sprocket shaft, and a chain covering the first sprocket and the second sprocket. The first sprocket is located between the second driven gear and the third driven gear.

6. The automatic marking device for chucks according to claim 1, characterized in that: The vision system component includes diffuse reflection cameras mounted on both sides of the end of the marking slide in the width direction. The diffuse reflection cameras are electrically connected to the control system. When the chuck slides to the end of the marking slide, the control system controls the rotating disk to stop working, and the marking machine moves downward to mark the chuck.

7. The automatic marking device for chucks according to claim 1, characterized in that: The movable driven gear includes a vertical compression rod connected inside the column of the base frame, a horizontal gear shaft sleeved on the vertical compression rod, and a fifth driven gear and a first winding wheel connected on the horizontal gear shaft. The fifth driven gear is located directly above the second driving gear, and the end of the second vertical frame away from the material barrel is also sleeved on the horizontal gear shaft. The first winding wheel is installed at the end of the horizontal gear shaft, and a pull rope is wound on the first winding wheel. A second winding wheel is installed on one side of the base frame directly above the first winding wheel, and the pull rope is connected to the push rod structure via the second winding wheel.

8. A marking method for an automatic marking device for chucks, based on the automatic marking device for chucks as described in claim 7, characterized in that: The marking method includes the following steps: S1: The chucks are sorted and output to the marking slide in a certain direction under the action of the rotating disk; S2: The correctly oriented chuck is output through the marking slide to the bottom of the marking machine for marking, while the incorrectly oriented chuck is blocked by the stop on the marking slide and slides from the opening into the return mechanism; S3: After marking is completed, the chuck slides down the marking slide into the receiving mechanism. When the chuck in the receiving mechanism accumulates a certain weight, the compression spring and the second vertical frame move downward. S4: The second vertical frame drives the fifth driven gear to move downward and mesh with the second driving gear. Under the action of the second driving gear, the first winding wheel winds and pulls the pull rope, and drives the push rod structure to move left and right along the horizontal bar, thereby pushing the material bucket and sliding it out along the inclined slide plate. S5: During the upward movement of the receiving tray in the chain drive mechanism, the elastic downward pressure of the elastic dial frame tilts the chuck in the receiving tray into the slide groove, and the chuck slides into the rotating disk through the slide groove. S6: Repeat the above steps until all the chucks in the rotating disk have completed the marking work.
