Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figure 1-4 As shown, this application provides a technical solution: an automatic feeding device for flipping and positioning metal workpieces, including a robotic arm 2 and a feeding unit 3, wherein the robotic arm 2 is located on one side of a CNC lathe 1;

[0030] The loading unit 3 includes a loading platform 31, which has a carrying unit capable of carrying metal workpieces 6 and finished parts 7. Several extension plates 32 extend outward from the side of the loading platform 31 near the robotic arm 2. A calibration seat 33 is installed at the end of the extension plate 32 away from the loading platform 31. A calibration hole 333 with the axis in the vertical direction is opened in the center of the calibration seat 33. The diameter of the calibration hole 333 is larger than the diameter of the metal workpiece, and it can keep the metal workpiece 6 in a vertical state and fall into the calibration hole 333. The robotic arm 2 is used to grab the blank at the calibration seat 33 and transfer it to the CNC lathe 1.

[0031] The top of the calibration hole 333 has a feed inlet 3331 with a sloping surface that is wider at the top and narrower at the bottom. The bottom diameter of the feed inlet 3331 is the same as that of the calibration hole 333. A magnet 334 for magnetically adsorbing metal workpieces is fixedly connected to the bottom inner wall of the calibration hole 333.

[0032] The calibration base 33 is fixedly connected to the extension plate 32.

[0033] The carrying unit includes several finished product trays 4 and several workpiece trays 5. Each workpiece tray 5 is located above each finished product tray 4. Several placement holes 41 for placing finished parts 7 are evenly arranged on the finished product tray 4, and several placement holes 51 for placing metal workpieces 6 are evenly arranged on the workpiece tray 5.

[0034] The number of placement holes 41 is the same as the number of material placement holes 51.

[0035] Several tracks 312 are fixedly connected to the top surface of the loading platform 31. Every two sets of tracks 312 are connected to the bottom of the finished product tray 4 so that the finished product tray 4 can slide on the loading platform 31 in the left and right direction.

[0036] A handle 42 is fixedly connected to the side of the finished plate 4 away from the robotic arm 2.

[0037] A workpiece table 311 is mounted on the top of the loading platform 31 at the end away from the robotic arm 2, and the workpiece tray 5 is located on top of the workpiece table 311.

[0038] The front end of the robotic arm 2 is provided with a front gripper 21 and a back gripper 22 on both sides. The front gripper 21 and the back gripper 22 face opposite directions and there are two of each in the front-back direction.

[0039] The CNC lathe 1 is equipped with a chuck 11 for clamping metal workpieces 6.

[0040] Working principle: The operator places the metal workpiece 6 in the loading hole 51 in the workpiece tray 5, starts the robotic arm 2, and controls the front gripper 21 to grip the metal workpiece 6. After gripping, the front gripper rotates the metal workpiece 6 180 degrees and moves it above the calibration hole 333 through the robotic arm 2. The front gripper is released, and the gripped metal workpiece 6 falls into the calibration hole 333 along the inclined surface of the feed port 3331. The attraction of the magnet 334 keeps the metal workpiece 6 vertical. The front gripper lifts the metal workpiece 6 again without it leaving the calibration hole 333. The front gripper is released, and the metal workpiece 6 falls to the bottom of the calibration hole 333. After the metal workpiece 6 is stable, the front gripper reaches the set position and clamps the metal workpiece 6. According to the set program, the robotic arm 2 sends the metal workpiece 6 into the chuck 11 for clamping. The CNC lathe 1 then processes the metal workpiece 6.

[0041] The robotic arm 2 controls the front gripper 21 to grip the metal workpiece 6 at the rear end. After gripping, the rear gripper rotates the metal workpiece 6 180 degrees and moves it above the calibration hole 333 via the robotic arm 2. The front gripper is released, allowing the gripped metal workpiece 6 to fall into the calibration hole 333. The rear gripper lifts the metal workpiece 6 again without it leaving the calibration hole 333. The front gripper is released, allowing the metal workpiece 6 to fall to the bottom of the calibration hole 333. After the metal workpiece 6 is stable, the rear gripper reaches the set position and holds the metal workpiece 6. According to the set program, the front gripper of the front gripper 21 holds the finished part 7 of the metal workpiece 6 that was gripped by the chuck 11 in the previous process. The metal workpiece 6 of the rear gripper is sent into the chuck 11 for processing again.

[0042] The front gripper 21 feeds the finished part 7 into the placement hole 41 on the finished part tray 4. When the finished part tray 4 is full, the finished part tray 4 full of finished parts 7 is pulled to the bottom of the workpiece table 311 by the handle 42, and the workers transfer the finished part 7.

[0043] In summary, this device, by setting a positioning seat 33 and opening a calibration hole 333 inside, flips the metal workpiece 6 so that it enters the calibration hole 333 for repositioning. After clamping the metal workpiece 6 to a certain height, it drops to correct the placement of the metal workpiece 6 and prevent deviations from occurring during clamping. This improves processing accuracy and solves the technical problem that deviations in the positioning process of metal workpieces due to differences in shape, size, and material, as well as the precision limitations of the equipment itself, can affect subsequent processing accuracy and product quality.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
