[0002] Across the vast landscape of modern manufacturing, the assembly quality of stamped parts remains a crucial criterion for measuring their ultimate performance and customer satisfaction. Especially in industries like automotive manufacturing, electronic equipment assembly, and precision machinery production, every subtle assembly step directly impacts the overall performance and durability of the stamped parts. Screws, as indispensable connectors, play a crucial role in the assembly of various equipment and stamped parts. They not only securely connect components but also withstand the stresses and vibrations of equipment operation. Therefore, the tightening and length of screws must be strictly controlled within specified parameters to ensure the reliability and stability of stamped parts.

[0003] However, rivet screws on stamped parts are typically riveted to specific locations on the parts, and their lengths are often measured manually using tools like vernier calipers and micrometers. This method is not only inefficient and unable to meet the demands of large-scale, high-efficiency production, but is also susceptible to human factors, such as visual fatigue, improper operation, and the accuracy limitations of measuring tools, which can lead to measurement errors.

[0031] refer to Figure 1As shown, a stamping part riveted screw mixed material detection machine includes a detection platform 1 and a detection fixture 2. The detection fixture 2 is arranged on the end face of the detection platform 1 and is used to support the stamping part 140 riveted with a screw 150. A lifting assembly 3 is fixed to the bottom of the detection platform 1, and a detector 4 is installed at the output end of the lifting assembly 3. The detection platform 1 is provided with a conductive hole 11. The detector 4 and the detection fixture 2 are located at both ends of the conductive hole 11. The stamping part 140 is supported on the detection fixture 2, and the screw 150 is arranged toward the detector 4. The lifting assembly 3 drives the detector 4 to move toward the screw 150 to detect the length of the screw 150.

[0032] Specifically, the stamping part 140 is riveted with four screws 150, and the end face of the stamping part 140 is affixed with a QR code that can identify the identity information of the stamping part 140. The upper end face of the stamping part 140 is provided with a mark with the hardness information of the stamping part 140, and the end face of the screw 150 has a mark with the hardness information of the screw 150.

[0033] refer to Figure 2 As shown, the lifting assembly 3 includes a slide rail 31 and a slider 32. The slide rail 31 is fixed to the bottom of the detection platform 1. Preferably, a bracket 13 is provided at the bottom of the detection platform 1. Specifically, the cross-section of the bracket 13 is "L"-shaped. One side of the bracket 13 is fixed to the bottom of the detection platform 1, and the other side is arranged perpendicular to the detection platform 1. The slide rail 31 is fixedly connected to the bracket 13 in the vertical direction. On the one hand, the slide rail 31 is fixed to the bottom of the detection platform 1, and on the other hand, the verticality of the slide rail 31 and the detection platform 1 is ensured.

[0034] The slider 32 is slidably connected to the side of the slide rail 31 facing away from the bracket 13, and the slider 32 is located at the bottom of the guide hole 11, that is, the slider 32 slides closer to or away from the guide hole 11 relative to the slide rail 31. Specifically, the slider 32 includes a first slider 321 and a second slider 322. The first slider 321 and the second slider 322 are bolted to each other perpendicularly. The first slider 321 is slidably connected to the slide rail 31. The end face of the second slider 322 is parallel to the end face of the detection fixture 2 to ensure the accuracy of the screw 150 detection. In this embodiment, the first slider 321 and the second slider 322 form an "L"-shaped structure, and the second slider 322 is provided with a plurality of mounting holes 323 for mounting the detector 4. In this embodiment, the number of mounting holes 323 is four, corresponding to the four screws 150 riveted on the stamping part 140. In other variant embodiments, the second slider 322 can have one or more mounting holes 323 to detect the length of the screws 150 on different stamping parts 140.

[0035] In this embodiment, the detector 4 is a contact displacement sensor. In other variations, the detector 4 may be an electric contact sensor or a laser sensor to detect the length of the screw 150. Specifically, the contact displacement sensor includes a contact 41 and a sensor body 42. The horizontal plane where the second slide 322 is located is used as the interface. The contact 41 passes through the mounting hole 323 and is located on the side of the second slide 322 close to the detection platform 1. The sensor body 42 is located on the side of the second slide 322 away from the detection platform 1. The contact displacement sensor is fixedly connected to the second slide 322, and the ends of the contacts 41 of the four contact displacement sensors are located on the same horizontal plane, so that the four contact displacement sensors can contact the corresponding screws 150 at the same time, ensuring detection accuracy and detecting unqualified screws 150, that is, screws 150 of different lengths.

[0036] A positioning base plate 12 is fixed to the end face of the inspection platform 1. This base plate 12 has a hole that communicates with the conductive hole 11. The detector 4 passes through the hole and then contacts the screw 150 on the inspection jig 2. The positioning base plate 12 is provided with positioning holes and positioning pins. The inspection jig 2 is plugged into the positioning holes via the positioning pins. While ensuring the positioning accuracy of the inspection jig 2, the inspection jig 2 and positioning base plate 12 are detachably connected, making it easy to replace the inspection jig 2 to accommodate different stamping parts 140, thereby improving inspection flexibility.

[0037] refer to Figure 3 As shown, the end face of the inspection jig 2 is provided with an identification hole 21, which houses a proximity sensor 22. The proximity sensor 22 is electrically connected to the lifting assembly 3. When the stamping part 140 to be inspected is placed on the inspection jig 2, the proximity sensor 22 identifies the stamping part 140 and transmits an electrical signal to the lifting assembly 3. The lifting assembly 3 then drives the detector 4 to rise, thereby detecting the length of the screw 150 on the stamping part 140.

[0038] refer to Figure 4 As shown, the detection jig 2 is provided with a plurality of limiting holes 23 for limiting the screws 150. The limiting holes 23 are through holes, and the limiting holes 23 are connected to the conductive holes 11 in the vertical direction. When the stamping part 140 is placed on the end face of the detection jig 2, the screws 150 are inserted into the limiting holes 23, and the ends of the screws 150 extend out of the limiting holes 23, so that the contact displacement sensor can touch the ends of the screws 150 to detect the length of the screws 150.

[0039] refer to Figure 5As shown, the detection platform 1 is fixed with a support assembly 6, which includes a support rod 61 and a first load-bearing rod 62. The support rod 61 is vertically arranged and fixedly connected to the end face of the detection platform 1. The support rod 61 and the first load-bearing rod 62 are detachably connected through a first adjustment assembly 7. The first adjustment assembly 7 includes a first adjustment rod 71, a first adjustment block 72 and a second adjustment block 73. In this embodiment, the first adjustment rod 71 is adjustably connected to the support rod 61 through the first adjustment block 72, and the first load-bearing rod 62 is adjustably connected to the first load-bearing rod 62 through the second adjustment block 73. Preferably, the support rod 61, the first load-bearing rod 62 and the first adjustment rod 71 are arranged perpendicular to each other.

[0040] An image recognition module 8 is fixed to one end of the first supporting rod 62 away from the second adjusting block 73. By adjusting the first adjusting block 72 and the second adjusting block 73, the image recognition module 8 is positioned directly above the inspection jig 2 to recognize information of the stamping part 140.

[0041] The image recognition module 8 includes a camera 81 and a lamp 82. Both the camera 81 and the lamp 82 are fixedly connected to the end of the first adjustment block 72 of the first bearing rod principle. The camera 81 is set toward the detection fixture 2. Preferably, the lamp 82 is set lower than the camera 81 to prevent the lamp 82 from irradiating the camera 81, causing a shadow on the surface of the stamping part 140, thereby reducing the impact on the detection of the camera 81. The lamp 82 is provided with a clearance hole 83, so that the line of sight of the camera 81 can pass through the clearance hole 83 to identify the stamping part 140.

[0042] The support assembly 6 further includes a second load-bearing rod 63, which is detachably connected to the support rod 61 via a second adjustment assembly 5. The second adjustment assembly 5 includes a second adjustment rod 51, a third adjustment block 52, and a fourth adjustment block 53. In this embodiment, the second adjustment rod 51 is adjustably connected to the support rod 61 via the third adjustment block 52, and the second load-bearing rod 63 is adjustably connected to the second load-bearing rod 63 via the fourth adjustment block 53. Preferably, the support rod 61, the second load-bearing rod 63, and the second adjustment rod 51 are arranged perpendicular to each other.

[0043] Specifically, the adjustable connection described above is a detachable connection. For example, the first adjustment block 72 is provided with two mutually perpendicular connection holes. The first adjustment block 72 flexibly engages with the support rod 61 through one of the connection holes, and flexibly engages with the first adjustment rod 71 through the other connection hole. The diameter of the connection hole is adjusted by a screw. Once the position of the first adjustment block 72 is adjusted, tightening the screw shrinks the connection hole, securing the first adjustment block 72 to the support rod 61 and the first adjustment block 72 to the first adjustment rod 71. Loosening the screw expands the diameter of the connection hole, allowing the first adjustment rod 71 to rotate and / or translate relative to the support rod 61 to adjust its position.

[0044] A QR code recognition module 9 is provided at the end of the second support rod 63 away from the fourth adjustment block 53. This module is angled toward the inspection jig 2. Preferably, the central axis of the module forms an acute angle with the end face of the inspection jig 2, more preferably, a 45° angle. Preferably, the first and second adjustment assemblies are located on opposite sides of the support rod 61. That is, the QR code recognition module 9 and the camera 81 are vertically staggered, avoiding the risk of the QR code recognition module 9 obstructing the camera 81's view.

[0045] refer to Figure 1 As shown, a stamping part riveting screw mixing detection machine includes a frame 100, a detection platform 1 is fixed on the frame 100, and the frame 100 is provided with an industrial computer 110 and an electric control box 120. The industrial computer 110 establishes a communication connection with the electric control box 120, the industrial computer 110 sends control instructions to the electric control box 120, and receives status feedback and equipment data from the electric control box 120. The proximity sensor 22, image recognition module 8, QR code recognition module 9 and lifting assembly 3 are all electrically connected to the industrial computer 110. The frame 100 is also provided with a touch screen display 130, which is connected to the industrial computer 110 to display the current working status and provide control for the operator.

[0046] Implementation principle: The stamping part 140 with the screw 150 riveted on it is manually placed on the detection jig 2. After the proximity sensor 22 senses the stamping part 140, it feeds back a signal to the lifting assembly 3. The slider 32 drives the detector 4 to move toward the screw 150, and the contact 41 of the detector 4 contacts the screw 150. If it is detected that the length of the screw 150 meets the standard, "Screw 150 length OK" is displayed on the display 130. If it is detected that the length of the screw 150 does not meet the standard, "Screw 150 length NG" is displayed on the display 130. At the same time, the image recognition module 8 and the QR code recognition module 9 simultaneously identify and detect the stamping part 140. If the image recognition module 8 detects that the mark on the screw 150 is consistent with the mark on the stamping part 140, "Screw 150 model OK" is displayed on the display 130. Otherwise, "Screw 150 model NG" is displayed on the display 130. The QR code recognition module 9 recognizes the QR code on the stamping part 140 to confirm the identity information of the stamping part 140. If the stamping part 140 is qualified in all three items, it will be manually taken out and placed in the qualified area. If any one item of the stamping part 140 is unqualified, it will be placed in the unqualified area.
