[0016] The above technical solution enables precise control of the rotation angle and speed of the shaft, thereby allowing for more accurate adjustment of the position and angle of the profiling fixture; ensuring that the screws can be accurately fastened to the product, further improving the fastening quality and avoiding poor fastening caused by angular deviation.

[0031] Example:
[0032] The present application will be further described in detail below with reference to Figures 1-4.
[0033] This application discloses an alternating dual-station device, including a base plate 1, an electric screwdriver 2, and a CCD camera 3.
[0034] A U-shaped bracket 4 is provided on the base plate 1. A horizontal linear module 5 is symmetrically arranged on the top of the bracket 4. A vertical linear module 6 is detachably arranged on the slider of the horizontal linear module 5. An electric screwdriver 2 and a CCD camera 3 are arranged on the vertical linear module 6.
[0035] Feeders 8 are symmetrically arranged on the center line of the base plate 1, and the feeders 8 are located within the stroke of the electric screwdriver 2 on the same side.
[0036] A horizontal linear module 7 is symmetrically arranged on both sides of the feeder 8 along the upper edge of the base plate 1, and a fixture is provided on the slider of the horizontal linear module 7.
[0037] See Figure 4 The fixture includes a base 15, which is detachably connected to the slider of the horizontal linear module 7. Guide rails 9 are symmetrically arranged on the base plate 1, located between the feeder 8 and the adjacent horizontal linear module 7. The base 15 is also slidably connected to the guide rails 9. The detachable connection between the base 15 and the slider of the horizontal linear module 7 facilitates fixture replacement according to different product requirements, enhancing the equipment's versatility. The slidable connection between the base 15 and the guide rails 9 provides better guidance and stability during fixture movement.
[0038] Stability ensures precise product positioning during screw fastening, which improves fastening quality, further guarantees product assembly quality, and reduces the defect rate caused by fixture movement deviation.
[0039] See Figure 4The base 15 has symmetrically arranged upright plates 10, and a rotating shaft is rotatably arranged between adjacent upright plates 10. The rotating shaft is parallel to the guide rail 9 and extends out of the upright plates 10 at both ends. A rotating plate 11 is arranged on the rotating shaft, and a detachable copying fixture 12 is arranged on the rotating plate 11, allowing the fixture to rotate flexibly. This not only allows the direction of the copying fixture 12 to be adjusted according to different screw fastening angle requirements to adapt to diverse product needs, but also facilitates loading and unloading by operators, improves the convenience of operation, and helps to improve overall production efficiency.
[0040] See Figure 4 A servo driver 13 is provided on one side of the upright plate 10 on the base 15. Either end of the rotating shaft is connected to the output shaft of the servo driver 13. It can precisely control the rotation angle and speed of the rotating shaft, thereby more accurately adjusting the position and angle of the contour jig 12. It ensures that the screws can be accurately fastened to the product, further improving the fastening quality and avoiding poor fastening problems caused by angle deviation.
[0041] See Figure 4 A photoelectric sensor 14 is also installed on the upright plate 10. A cam is installed on the shaft end on the same side as the photoelectric sensor 14 and is located within the sensing range of the photoelectric sensor 14. Through the cooperation of the photoelectric sensor 14 and the cam, the rotation position and angle of the shaft can be accurately detected, providing more precise feedback control for the equipment. This helps to achieve precise operation in the automated production process, ensure the consistency of the locking process of each product, and thus improve the overall product quality and production stability.
[0042] The implementation principle of an alternating dual-station device according to an embodiment of this application is as follows: When the device is working, the feeder 8 provides screws to the electric screwdriver 2. The horizontal linear module 7 drives the fixture to move to a suitable position, and the base 15 in the fixture ensures the stability of movement through the guide rail 9.
[0043] The servo driver 13 controls the rotation of the rotating shaft, which drives the contour jig 12 on the rotating plate 11 to adjust to a suitable angle for placing the product.
[0044] Electric screwdriver 2 moves to feeder 8 to pick up screws under the drive of horizontal and vertical linear modules 6, and then moves to the top of the fixture to fasten the screws.
[0045] Before screw fastening, CCD camera 3 detects foreign objects in the screw hole, and after fastening, it checks for any abnormalities in the nut. Throughout the process, photoelectric sensor 14 monitors the shaft position via a sensing cam, providing precise feedback control to the equipment and enabling an automated, high-precision screw fastening and inspection process.
[0046] This application greatly improves hard drive assembly quality, production capacity, and yield, while saving manpower and reducing work intensity. Torque data is tracked in real time. The equipment is equipped with a dual-station synchronous working system, where the two stations can operate independently without interference. While one station is performing a screw-tightening task, the other station has already prepared the next screw to be processed, ensuring the continuity of the production line and effectively improving production efficiency.
[0047] It should be noted that the CCD camera, electric screwdriver, servo driver, photoelectric sensor and other technologies mentioned in this application are all mature existing technologies in the field. The improvement of automation level by electrical control connection between the above devices is well known to those skilled in the art. Therefore, their structure and principle will not be described in detail in the application documents. What this application seeks to protect is not the structure and principle of the above devices, but the technical effect achieved by the combination of the above devices.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
