[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5This application provides a clear and complete description of the technical solution. The described embodiments are merely possible technical implementations of this utility model and do not represent the complete implementation of all components. Those skilled in the art can, in conjunction with the embodiments of this utility model, obtain other embodiments without creative effort, and these embodiments are also within the protection scope of this utility model.

[0037] The inventors of this application have discovered that existing riveting machines typically only achieve automatic assembly and riveting. To ensure the yield rate of finished rivets, it is usually necessary to inspect the appearance of the parts before processing with a riveting machine, and also to inspect the finished product after processing. However, manual inspection is inefficient and cannot effectively guarantee the accuracy of automatic riveting processing. Therefore, this application mainly provides an automatic riveting and inspection device, which can improve the efficiency and accuracy of riveting processing. The following is a further detailed description of this application.

[0038] This application provides an automatic rivet and detection device, referring to... Figure 1 The device includes a frame 1, a riveting conveyor 11 mounted on the frame 1, and a conveying drive device 12 for driving the riveting conveyor 11. It also includes a workpiece feeding mechanism 2, an incoming material inspection mechanism 3, a feeding mechanism 4, an assembly mechanism 5, a rivet feeding mechanism 6, a riveting mechanism 7, a finished product inspection mechanism 8, and a discharge mechanism 9 mounted on the frame 1. The workpiece feeding mechanism 2 is sequentially connected to the incoming material inspection mechanism 3 and the feeding mechanism 4. The assembly mechanism 5 is connected to the feeding mechanism 4 and the rivet feeding mechanism 6. The assembly mechanism 5, the rivet feeding mechanism 6, the riveting mechanism 7, the finished product inspection mechanism 8, and the discharge mechanism 9 are sequentially mounted on one side of the riveting conveyor 11. The workpiece feeding mechanism 2 is used to transport the workpieces to be processed to the incoming material inspection mechanism 3, which is used to inspect the workpieces to be processed. The feeding mechanism 4 is used to transport the inspected workpieces to be processed to the riveting conveying trough 11. The rivet feeding mechanism 6 is used to transport the rivets to be processed to the riveting conveying trough 11. The riveting conveying trough 11 is used to transport the workpieces and finished products between the assembly mechanism 5, the rivet feeding mechanism 6, the riveting mechanism 7, the finished product inspection mechanism 8, and the discharge mechanism 9 under the drive of the conveying drive device 12. The assembly mechanism 5 is used to assemble the rivets and workpieces together. The riveting mechanism 7 is used to perform riveting processing on the assembled rivets and workpieces. The finished product inspection mechanism 8 is used to inspect the processed finished products and determine whether the finished products are good or defective. The discharge mechanism 9 is used to unload the good finished products and discharge the defective finished products.

[0039] The implementation principle of this embodiment is as follows: by integrating the entire process of rivet processing, including feeding, incoming material inspection, conveying, assembly, riveting, finished product inspection and defect removal, into one device, no manual intervention is required throughout the process, which can effectively improve the efficiency and accuracy of rivet processing.

[0040] like Figure 1 and Figure 2 As shown, the workpiece feeding mechanism 2 of this embodiment includes a workpiece vibratory feeder 21, two workpiece feeding channels 22, and two first pushing devices 23. The input ends of the two workpiece feeding channels 22 are connected to the output ends of the workpiece vibratory feeder 21, and the output ends of the two workpiece feeding channels 22 are respectively connected to the two first pushing devices 23. The first pushing devices 23 are used to push the workpieces to be processed output from the workpiece feeding channels 22 to the incoming material inspection mechanism 3. The workpieces to be processed are automatically fed through the cooperation of the vibratory feeder, the feeding channels, and the pushing devices, and the feeding is carried out simultaneously through two feeding channels, which effectively improves the workpiece feeding efficiency. In the specific implementation process, the clamp at the bottom of the first pushing device 23 moves up and down and left and right through the cylinder and the slide rail, which can clamp the workpieces output from the feeding channels and push them to the incoming material inspection mechanism 3.

[0041] like Figure 1 and Figure 2 As shown, the incoming material inspection mechanism 3 of this application embodiment includes two appearance inspection devices 31, which are respectively located at the ends of the two workpiece feeding channels 22. The appearance inspection devices 31 are used to inspect the holes and external dimensions of the workpieces to be processed. By inspecting the holes and external dimensions of the workpieces to be processed by the appearance inspection devices 31, it is ensured that the workpieces to be processed meet the standards. At the same time, the front and back of the fed workpieces can also be determined by the size of the holes. In specific implementation, the appearance inspection devices 31 can adopt visual inspection, infrared inspection, and optical inspection, etc.

[0042] like Figure 1 and Figure 2As shown, the feeding mechanism 4 in this embodiment includes two second pushing devices 41, two rotating devices 42, two pushing channels 43, two third pushing devices 44, and two fourth pushing devices 45 connected in sequence. The second pushing devices 41 are used to move the workpiece to be processed after being detected by the detection device to the rotating devices 42. The rotating devices 42 are used to perform forward and reverse correction on the workpiece to be processed. The third pushing devices 44 are used to move the forward and reverse corrected workpiece to be processed to the fourth pushing devices 45 through the pushing channels 43. The fourth pushing devices 45 are used to push the workpiece to be processed output from the two pushing channels 43 to the riveting conveying groove 11. Through pushing and forward and reverse correction, it is ensured that the forward and reverse directions of the workpiece to be processed entering the riveting conveying groove 11 meet the requirements, thereby ensuring the accuracy of riveting. In the specific implementation process, the rotating device 42 is a rotary cylinder. When the workpiece to be processed enters the rotating device 42, if it is visually inspected as facing forward, it does not need to be rotated and directly enters the pushing channel 43. If it is visually inspected as facing backward, it is rotated by the rotary cylinder to face forward before entering the pushing channel 43. The second pushing device 41 and the third pushing device 44 can move left and right by cylinders, and the fourth pushing device 45 can move back and forth by cylinders, pushing the workpieces output from the two pushing channels 43 into a riveting conveying groove 11.

[0043] like Figure 1 and Figure 3 As shown, the assembly mechanism 5 of this embodiment includes two assembly devices 51, which are sequentially installed on one side of the riveting conveying groove 11. Each assembly device 51 includes two rivet input holes 511 at the top and two rivet output holes 512 at the bottom. The rivet feeding mechanism 6 includes a rivet vibratory feeder 61 and four rivet feeding channels 62, which are respectively connected to the two rivet input holes 511 of the two assembly devices 51. Rivets enter the rivet input holes 511 of the assembly device 51 through the feeding channels, and then exit from the rivet output holes 512 and are assembled with the workpiece, realizing automatic rivet assembly and improving rivet processing efficiency. In specific implementation, the assembly device 51 can move up, down, left, and right by a cylinder or motor to ensure that the rivet output holes 512 are aligned with the workpiece on the riveting conveying groove 11.

[0044] like Figure 1 and Figure 4As shown, the riveting mechanism 7 of this embodiment includes two riveting devices 71, which are sequentially installed on one side of the riveting conveying groove 11. The riveting mechanism 7 also includes two sets of clamping devices 72, which are respectively installed on both sides of the riveting conveying groove 11 and directly opposite the bottom of the riveting devices 71. The clamping devices 72 clamp the workpiece during riveting operations. In practice, the riveting devices 71 can move up and down under the drive of a cylinder or motor to rivet the workpiece on the riveting conveying groove 11, ensuring the accuracy of the riveting process.

[0045] like Figure 1 As shown, in this embodiment of the application, the distance between each adjacent assembly device 51 and riveting device 71 is the same, and the distance that the conveying drive device 12 drives the workpiece to move each time is also the same, ensuring that the device can perform assembly and riveting processing without interruption, and can assemble and rivet two products at the same time, effectively improving the processing efficiency of rivets.

[0046] like Figure 1 and Figure 5 As shown, the finished product inspection mechanism 8 of this application embodiment includes two CCD inspection devices 81 and two light-shielding plates 82. The two CCD inspection devices 81 are sequentially installed on one side of the riveting conveying groove 11, and the two light-shielding plates 82 are respectively installed on the other side of the riveting conveying groove 11 and face the lens of the CCD inspection device 81. The finished product processed by the rivets is inspected using CCD. CCD inspection has the advantages of high precision, high efficiency, and high reliability. By setting the light-shielding plates 82, the accuracy of CCD inspection can be further improved.

[0047] like Figure 1 and Figure 5 As shown, the feeding mechanism 9 of this embodiment includes two feeding devices 91, which are sequentially installed on one side of the riveting conveying groove 11. Each feeding device 91 can push the finished product towards the other side of the riveting conveying groove 11. The frame 1 has a feeding hole 92 at its bottom corresponding to the pushing direction, and a defective product collection frame is provided at the bottom of the feeding hole 92. The feeding devices 91 arrange the defective products detected by the CCD inspection device 81 and push them to the feeding hole 92, where they fall into the defective product collection frame. This eliminates the need for manual collection of defective products, further improving processing efficiency. In specific implementation, the feeding device pushes the product by moving a cylinder back and forth.
