Description

[0002] In modern industrial production, screws are essential fasteners, and their quality and precision directly impact product performance and reliability. Therefore, screw sorting is particularly crucial in industrial production. Traditionally, screw sorting relies primarily on manual labor, which is not only inefficient but also susceptible to human factors, resulting in unstable sorting quality. With the continuous advancement of automation and optical inspection technologies, automatic optical screw sorting machines have emerged. These machines utilize optical recognition technology to automatically sort screws, significantly improving sorting efficiency and accuracy.

[0003] Existing automatic optical screw sorting machines mainly rely on the camera's recognition algorithm to identify screw specifications. If the algorithm's recognition speed and accuracy are not high, it will affect the efficiency and accuracy of the entire sorting process. In addition, when processing screws of different types and specifications, existing equipment often needs to replace different camera modules or adjust the camera parameters, which increases the complexity and difficulty of operation of the equipment. Existing equipment usually has only one discharge port in the design of the discharge module, which limits the sorting capacity of the equipment and cannot meet the needs of sorting more types of screws. Finally, the existing equipment mainly uses vibration in the design of the vibration plate. If the shape or material of the screw does not match the design of the vibration plate, it may affect the forward push of the screw, thereby affecting the entire sorting process.

[0034] like Figures 1 to 10 As shown, the automatic optical screw sorting machine of the present invention includes a feeding module 1, a vibrating plate 2, a rotating plate module 9, camera modules 7 and 8, and a discharging module 10. The feeding module 1 is arranged on the top of the machine and includes a feeding hopper 110, a feeding barrel 120, and a hopper 130, which are used to receive and stabilize the input of screws.

[0035] The vibrating plate 2 is placed at the screw discharge port and fixed to the machine structure via the base plate 3, providing stable support. The vibrating plate 2 pushes the screws forward by vibrating and is connected to the vibrating conveying module 11, which is used to convey the screws from the vibrating plate 2 to the rotating plate module 9.

[0036] The rotating disc module 9 is located at the discharge position of the vibrating disc 2 and consists of a motor base 910, a servo motor 920, a speed reduction mechanism 930, and a rotating outer disc 940.

[0039] The discharge module 10 includes a solenoid valve 102 and a push rod 101. Based on feedback from a computer terminal, the solenoid valve 102 drives the push rod 101 to deliver the screws to the corresponding discharge port.

[0041] Working Principle: The automatic optical screw sorting machine of this utility model achieves automatic screw sorting through the following steps. First, the screws pass through the feed hopper 110 and into the feed barrel 120. Then, through the hopper 130, they enter the vibrating plate 2. The vibrations generated by the electromagnetic vibrator in the vibrating plate 2 propel the screws forward. From the vibrating plate 2, the screws enter the rotating plate module 9. The rotating plate module 9 is driven by a servo motor 920 through a reduction mechanism 930 to rotate the outer disc 940. The screws are guided to the same circumference by the first guide mechanism 5 and the second guide mechanism 6. When the screws are on the rotating plate 940, the first camera module 7 and the second camera module 8 identify the screws, determining their size and length, and transmit the identification information to a computer terminal. The computer terminal processes the identification information and sends a feedback signal to the solenoid valve 102 of the discharging module 10. The solenoid valve 102 drives the push rod 101 to deliver the screws to the corresponding discharging port. The discharging module 10 is equipped with multiple discharging ports to accommodate the sorting needs of screws of different types and specifications. The display module 13 displays information during the sorting process, and the three-color light 14 indicates the working status of the equipment.

[0042] Through the above steps, the automatic optical screw sorting machine of the present invention can efficiently and accurately complete the automatic sorting of screws, improve production efficiency, and reduce the complexity and errors of manual operations.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
