[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an online robotic automatic sorting machine for SMD warehousing production, including a feeding module 1, a sorting station 2, a unloading robot 3, and a verification and unloading device 4. The feeding module 1 is equipped with multiple sponge suction cups 5 on its top, which are connected to a vacuum pump 6 via pneumatic pipelines, and each sponge suction cup 5 is equipped with a pressure sensor 7 at its bottom. The sorting station 2 includes an industrial camera 8 mounted on the top and a rotating platform 26 located below the industrial camera 8. The rotating platform 26 is equipped with a positioning pin 9 at its center and is driven by a stepper motor. The unloading robot 3 is equipped with a gripper assembly 10 at its end. The gripper assembly 10 includes two symmetrically distributed arc-shaped grippers 11, and the inner surface of the arc-shaped grippers 11 is provided with anti-slip texture. The gripper assembly 10 is controlled to open and close by a servo motor. The verification and unloading device 4 includes an unloading guide rail 12 and a recycling bin 13 located at its end. A pushing cylinder 14 is provided on the unloading guide rail 12.

[0024] Specifically, a lifting mechanism 15 is fixed at the bottom of the feeding module 1. The lifting mechanism 15 includes two parallel lead screws 16 and a synchronous belt 17. The lead screws 16 are connected to the output shaft of a stepper motor via a coupling. The two ends of the synchronous belt 17 are fixedly connected to the nut seats on the two lead screws 16, respectively. Through the above arrangement, the sponge suction cup 5 can rise and fall with the movement of the lifting mechanism 15, thereby adapting to the suction of SMD components of different heights. When a component needs to be suctioned, the lifting mechanism 15 drives the sponge suction cup 5 to descend to the position of the component. The vacuum pump 6 provides negative pressure to the sponge suction cup 5 through the pneumatic pipeline, so that the sponge suction cup 5 firmly adheres to the component.

[0025] Specifically, the industrial camera 8 is fixed above the sorting station 2 by a bracket. A ring light source 18 is located at the bottom of the industrial camera 8, connected to the camera's housing via a flexible bracket. A light shield 19 is located around the ring light source 18. These features reduce interference from external light during shooting, improving image quality. When the SMD component on the rotating platform rotates to a position below the industrial camera 8, the camera takes a picture and transmits the image to the control system for processing. The control system determines the component's type and location based on the image recognition results. Next, the control system controls the unloading robot 3 to move to the corresponding position. The gripper assembly 10, controlled by a servo motor, opens and closes to pick up the identified component and moves it to the designated location. If the component type is unsuitable or defective, the control system controls the verification and unloading device 4 to operate. The push cylinder 14 pushes the defective component along the unloading guide rail 12 into the recycling bin 13, achieving automatic unloading. Specifically, the gripper assembly 10 also includes an elastic compensation mechanism, which consists of a spring and a limiting block. The spring is sleeved on the outside of the gripper shaft, with one end fixedly connected to the gripper and the other end in contact with the limiting block. The limiting block is fixed inside the housing of the gripper assembly 10.

[0026] Specifically, the piston rod end of the push cylinder 14 is provided with a push plate 20, and the bottom of the push plate 20 is provided with a roller 21. The roller 21 rolls with the upper surface of the ejection guide rail 12, and guide plates 22 are provided on both sides of the push plate 20. The guide plates 22 are slidably connected to the side walls of the ejection guide rail 12. Through the above settings, the push cylinder 14 pushes the defective SMD components more smoothly, reduces the resistance caused by friction, and improves the pushing efficiency. The roller 21 and guide plates 22 also ensure the accuracy of the push cylinder 14 during the pushing process, avoiding component damage or jamming caused by deviation. After the push cylinder 14 pushes the defective component into the recycling bin 13, the sensor in the recycling bin 13 will detect the arrival of the component and send a signal to the control system. After receiving the signal, the control system will control the push cylinder 14 to reset, waiting for the next pushing task.

[0027] Specifically, the sponge suction cup 5 is mounted on the movable plate 23, which is fixedly connected to the nut seat. Guide grooves 24 are provided on both sides of the movable plate 23, and these guide grooves 24 slide in engagement with guide posts 25 on the side wall of the feeding module 1. This design makes the sponge suction cup 5 more stable during lifting and lowering, preventing suction failure or component damage due to shaking. Simultaneously, the cooperation between the guide grooves 24 and the guide posts 25 ensures the accuracy of the sponge suction cup 5 during lifting and lowering, enabling it to accurately reach the designated position for suction.

[0028] Specifically, the guide plates 22 on both sides of the push plate 20 are L-shaped. Their vertical parts are fixedly connected to the push plate 20, and their horizontal parts contact the side wall of the ejector guide rail 12. The surface of the guide plates 22 is provided with a wear-resistant coating. Through the above configuration, the guide plates 22 can reduce wear and extend their service life when sliding in contact with the side wall of the ejector guide rail 12 for a long time. The wear-resistant coating also ensures the smoothness of the guide plates 22 during the sliding process, avoiding pushing difficulties or jamming caused by increased frictional resistance.

[0029] A specific application example of this embodiment is as follows:

[0030] In use, the feeding module 1 moves the sponge suction cup 5 up and down via the lifting mechanism 15. The pressure sensor 7 monitors the suction cup's gripping status in real time to ensure the product is firmly gripped. The rotating platform of the sorting station 2 is driven by a stepper motor to rotate the product to the optimal recognition angle. The industrial camera 8, in conjunction with the ring light source 18, reads the label content and transmits the verification results to the control system. The unloading robot 3 grips qualified products through the gripper assembly 10 and places them in the designated position according to the verification results. The elastic compensation mechanism of the gripper assembly 10 ensures that the gripping force is moderate and avoids damage to the product. Unqualified products are pushed into the recycling bin 13 by the push cylinder 14 along the unloading guide rail 12, completing the automatic sorting process.
