The swing cylinder 13 can drive the clamping jaw 8 to clamp and open, and the clamping jaw 8 can clamp the bar stock on the V-shaped positioning block 7 so that the dedicated machine tool 2 can process the bar stock 9.

[0045] The frame 1 has a feeding trough 4 below the discharge port of the vibrating storage bin 3. A bar stock pushing cylinder 5 is installed at one external end of the feeding trough 4, and a positioning groove 19 is installed at the other external end. The telescopic end of the bar stock pushing cylinder 5 faces the feeding trough 4. The vibrating storage bin 3 is mounted on the frame 1 via four columns 14. Springs 15 are installed above the columns 14. The vibrating storage bin 3 can slide along the axial direction of the columns 14. A vibrating motor 16 is installed on the vibrating storage bin 3. Bar stock 9 is placed in the vibrating storage bin 3. When the vibrating motor 16 operates, the vibrating storage bin 3 vibrates slightly, allowing the bar stock 9 to fall smoothly into the feeding trough 4. The vibrating storage bin 3 stores more than 100 bars of bar stock 9. A real-time weighing device is installed at the bottom of the vibrating storage bin 3, which can weigh the bin (including the bar stock 9) in real time. The real-time weighing device is electrically connected to the control cabinet 17 so that the control cabinet 17 can issue an alarm when the weight is less than a threshold.

[0046] The bar stock 9 falls from the discharge port of the vibrating storage bin 3 into the feeding trough 4. The bar stock pushing cylinder 5 can push the bar stock 9 into the positioning groove 19, waiting for the robot arm 6 to grab the bar stock 9.

[0047] The robotic arm 6 is positioned inside the vibrating storage bin 3, and it can move above the positioning slot 19 and the dedicated machine tool worktable 20. Specifically, as shown...

The robotic arm mounting frame 605 is mounted on the frame 1; the slide rail 606 is provided on the robotic arm mounting frame 605; the robotic arm mounting frame 605 is L-shaped.

[0048] The X-axis cylinder 601 is mounted on the robot arm mounting frame 605, and its telescopic end is connected to the Y-axis cylinder 602. The Y-axis cylinder 602 is slidably mounted on the slide rail 606. The telescopic end of the Y-axis cylinder 602 is connected to the Z-axis cylinder 603. The telescopic end of the Z-axis cylinder 603 is connected to the gripper cylinder 604. The gripper cylinder 604 is equipped with a gripper 607.

The Y-axis cylinder 602 can drive the Z-axis cylinder 603 and its components to move along the Y-axis direction. The Z-axis cylinder 603 can drive the gripper cylinder 604 and the gripper 607 to move along the Z-axis direction, thus realizing the three-axis movement and clamping of the robot arm 6.

[0049] The robotic arm 6 can pick up the bar stock 9 in the positioning groove 19 and place it onto the V-shaped positioning block 7 on the special machine tool worktable 20; it can also pick up the semi-finished bar stock 9 processed by the special machine tool 2 from the V-shaped positioning block 7 and place it onto the trough conveyor belt 10.

[0050] A trough-shaped conveyor belt 10 is installed on the frame 1; the input end of the trough-shaped conveyor belt 10 is located in front of the dedicated machine tool worktable 20, and the output end of the trough-shaped conveyor belt 10 is provided with a semi-finished product hopper 11. The trough-shaped conveyor belt 10 is connected to a transmission belt drive motor 12. The trough-shaped conveyor belt 10 transports the semi-finished bar stock 9 processed by the dedicated machine tool 2 into the semi-finished product hopper 11.

[0051] In the above scheme, a control cabinet 17 and an air pump 18 are provided on the frame 1. The control cabinet 17 is used to control various electrical control components and control the actions of various parts; the air pump 18 is used to provide a power source for various pneumatic devices.

[0052] The working process of an automatic feeding system for bar stock processing according to this utility model is as follows:

[0053] 1. When the vibrating motor 16 is working, the vibrating storage bin 3 vibrates slightly, and the bar stock 9 falls from the discharge port of the vibrating storage bin 3 into the feeding trough 4. The bar stock pushing cylinder 5 can push the bar stock 9 into the positioning groove 19, waiting for the robot arm 6 to grab the bar stock 9.

[0054] 2. X-axis cylinder 601 and Y-axis cylinder 602 control the movement of the robotic arm 6, Z-axis cylinder 603 controls the lifting and lowering of the robotic arm 6, and gripper cylinder 604 controls the opening and closing of the gripper 607. When the robotic arm 6 is at the origin position, first X-axis cylinder 601 and Y-axis cylinder 602 are activated, and the robotic arm 6 moves to directly above the bar stock 9 in the positioning groove 19. Then, gripper cylinder 604 is activated, and gripper 607 opens. At the same time, Z-axis cylinder 603 is activated, and after the robotic arm 6 descends to the position, gripper cylinder 604 is activated, and gripper 607 closes, clamping the bar stock 9. After clamping the bar stock 9, the Z-axis cylinder 603 is activated, and the robot arm moves upward into position. Then, the Y-axis cylinder 602 and the X-axis cylinder 601 are activated, and the robot arm 6 moves to above the V-shaped positioning block 7. The Z-axis cylinder 603 is activated, and the robot arm 6 descends into position. Then, the gripper cylinder 604 is activated, and the gripper 607 opens, placing the bar stock 9 on the V-shaped positioning block 7. The Z-axis cylinder 603 is activated, and the robot arm moves upward into position. Then, the X-axis cylinder 601 is activated, and the robot arm moves forward and stops outside the processing area of ​​the special machine tool 2, making it convenient for the special machine tool 2 to process the bar stock 9.

[0055] 3. The swing cylinder 13 actuates, and the clamping jaws 8 clamp the bar stock 9, realizing the clamping function of the bar stock 9 for easy processing. Then the special machine tool 2 works, first flattening the end face of the bar stock 9, and then drilling the center hole. After the bar stock 9 is processed, the swing cylinder 13 actuates, and the clamping jaws 8 release the bar stock 9, waiting for the robot arm 6 to grab the bar stock 9.

[0056] 4. When X-axis cylinder 601 is activated, the robot arm 6 moves backward to above the V-shaped positioning block 7. When Z-axis cylinder 603 is activated, the robot arm 6 moves downward to its designated position. Then, gripper cylinder 604 is activated, and gripper 607 closes to clamp the bar stock 9 on the V-shaped positioning block 7. When Z-axis cylinder 603 is activated, the robot arm 6 moves upward to its designated position. When X-axis cylinder 601 is activated, the robot arm moves forward to above the input end of the trough conveyor belt 10. When Z-axis cylinder 603 is activated, the robot arm 6 moves downward. Then, gripper cylinder 604 is activated, and gripper 607 releases the bar stock 9 onto the trough conveyor belt 10. When Z-axis cylinder 603 is activated, the robot arm moves upward to its designated position. Then, Y-axis cylinder 602 is activated, and the robot arm moves to the left to above the positioning groove 19 to begin the next material handling and feeding cycle.

[0057] 5. The bar stock 9 moves with the trough conveyor belt 10 and rolls into the semi-finished product hopper 11. After the semi-finished product hopper 11 is full, it is moved into the warehouse for storage.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
