[0032] like Figures 1 to 4 As shown, in this embodiment, a device for riveting quality inspection includes:

[0033] Workbench 100, which has a testing area;

[0034] The detection device includes an image capturing component 200 and a sensing component 300. The image capturing component 200 is located above the detection area and is used to collect image data of the workpiece riveting. The sensing component 300 is located at the end of the detection area and is used to detect the position information of the workpiece.

[0035] A workpiece conveyor belt that can rotatably extend into the inspection area to transport the workpiece to be inspected to the inspection area;

[0036] The control system is electrically connected to the imaging component 200, the sensing component 300, and the workpiece conveyor belt. When the sensing component 300 detects that the entire workpiece has entered the detection area, it sends an electrical signal to the control system, which then triggers the imaging component 200 to take a picture. This design ensures that the imaging component 200 only takes a picture after the sensing component 300 confirms that the entire workpiece has entered the detection area, avoiding invalid shots. This not only ensures the integrity of image acquisition and reduces the risk of misjudgment, but also effectively improves the accuracy of workpiece riveting quality detection, while saving system resources and power consumption. Furthermore, the real-time feedback mechanism formed by the sensing component 300 eliminates the need for fixed waiting time in traditional equipment, making the detection process more efficient, avoiding unnecessary downtime, and improving the overall efficiency of the detection process.

[0037] like Figures 1 to 2As shown, specifically, the workbench 100 is rectangular, comprising a hollow rectangular frame 110 formed by splicing multiple horizontal and vertical beams, and several baffles 120 disposed on the frame 110 to form a closed state. The baffles 120 cooperate with the frame 110 to form a receiving cavity, serving as a detection area, and capable of accommodating components such as the imaging component 200, the sensing component 300, and the workpiece conveyor belt. Preferably, a storage cabinet is also provided directly below the receiving cavity, which can be used to store other items and also provides support for the workpiece conveyor belt, improving the overall strength of the equipment.

[0038] In this embodiment, the workpiece conveyor belt is horizontally arranged and rotatably passes through the receiving cavity. One end of the workpiece conveyor belt extends to the outside left side of the worktable 100 to receive the workpiece to be tested, and the other end extends to the outside right side of the worktable 100 to transport the workpiece after inspection. This design allows the workpiece to move to the inspection area for riveting quality inspection as the workpiece conveyor belt rotates, and then leave the inspection area after inspection. This achieves automatic loading and unloading of workpieces during riveting quality inspection, effectively improving the efficiency of workpiece riveting quality inspection.

[0039] The workpiece conveyor belt can be a single-section design or a multi-section design. Preferably, in this embodiment, the workpiece conveyor belt adopts a multi-section design. This facilitates the disassembly, assembly, and maintenance of the workpiece conveyor belt, and also enables independent operation of each area of ​​the workpiece conveyor belt, improving the stability of equipment operation.

[0040] In this embodiment, the workpiece conveyor belt includes a first conveyor belt 400 and a second conveyor belt 410 that are independent of each other and connected in a straight line. The first conveyor belt 400 is rotatably disposed outside the detection area, while the second conveyor belt 410 is rotatably disposed within the detection area. The workpiece can be conveyed between the first conveyor belt 400 and the second conveyor belt 410. When the sensing component 300 detects that the entire workpiece has entered the detection area, the sensing component 300 feeds back an electrical signal to the control system. The control system triggers the imaging component 200 to take a picture based on the electrical signal and controls the first conveyor belt 400 to stop rotating. By setting the workpiece conveyor belt as two independently operating first conveyor belts 400 and second conveyor belts 410, the workpiece conveyor belt can achieve partial pause. That is, by pausing the first conveyor belt 400, new workpieces can be prevented from entering the detection area, avoiding interference with the workpiece being detected. The second conveyor belt 410 continues to run, ensuring that the dynamic detection process of the current workpiece is not disturbed, thereby improving the overall detection efficiency and ensuring the stability of the system. Furthermore, when either conveyor belt fails, it can be maintained individually, effectively improving the convenience of maintenance.

[0041] In this embodiment, the first conveyor belt 400 and the second conveyor belt 410 are on the same straight line, and the length of the second conveyor belt 410 is adapted to the length of the detection area. This design ensures that the workpiece can smoothly and continuously transition from the first conveyor belt 400 to the second conveyor belt 410, thereby entering the detection area for inspection. This layout not only simplifies the structural design of the system but also ensures the stability and consistency of the workpiece during the conveying process, reducing the impact of possible positional shifts or instabilities on the detection results.

[0042] In this embodiment, the workpiece conveyor belt also includes an independently operating third conveyor belt 420. The third conveyor belt 420 is located outside the inspection area and is connected to the end of the second conveyor belt 410 opposite to the first conveyor belt 400, and is on the same straight line as the second conveyor belt 410. Because the third conveyor belt 420 operates independently, the system can flexibly adjust the working state of each part according to actual needs. For example, when fine inspection is required, the speed of the second conveyor belt 410 can be slowed down to ensure inspection quality; while under high capacity requirements, the speed of the third conveyor belt 420 can be increased to improve output efficiency. Furthermore, the independent design of the first conveyor belt 400, the second conveyor belt 410, and the third conveyor belt 420 allows for individual maintenance when a problem occurs with a single conveyor belt, without stopping the entire production line, thus improving the convenience of maintenance and the continuity of production.

[0043] To enable independent operation of the first conveyor belt 400, the second conveyor belt 410, and the third conveyor belt 420, in this embodiment, each of the three conveyor belts is equipped with a drive unit 500. These drive units 500 are electrically connected to the control system and, under the control of the control system, drive the first conveyor belt 400, the second conveyor belt 410, and the third conveyor belt 420 to rotate. Preferably, the drive unit 500 is a rotary motor.

[0044] In this embodiment, a first gap 600 exists between the first conveyor belt 400 and the second conveyor belt 410, and a second gap 610 exists between the second conveyor belt 410 and the third conveyor belt 420. Both the first gap 600 and the second gap 610 are smaller than the outer diameter of the workpiece. This design not only ensures a smooth transition of the workpiece between different conveyor belts, avoiding the risk of the workpiece falling or getting stuck, but also provides ideal sensing conditions for the sensing component 300.

[0045] like Figures 2 to 4As shown, to achieve automated inspection of workpiece riveting quality, this embodiment includes a detection device comprising an imaging component 200 and a sensing component 300 mounted on the worktable 100. The imaging component 200 is positioned directly above the detection area to acquire image data of the workpiece riveting and feeds this data back to the control system for analysis and judgment. The sensing component 300 is located at the end of the detection area to detect the workpiece's position information and feeds it back to the control system, enabling the control system to accurately trigger the imaging component 200 to take a picture at an appropriate time.

[0046] like Figure 2 , Figure 3 As shown, in this embodiment, the imaging component 200 includes an imaging structure 210 and a supplementary lighting structure 220 movably disposed within the accommodating cavity of the worktable 100 and positioned above the second conveyor belt 410. This layout ensures that the imaging structure 210 can comprehensively acquire image data of the workpiece riveting from the optimal angle, and, in conjunction with the supplementary lighting structure 220, ensures that the imaging structure 210 can obtain high-quality images under different environments. Furthermore, the movable design of the imaging component 200 not only allows for adjustment of its position according to actual needs, thereby obtaining the optimal shooting angle and lighting conditions and improving the accuracy and quality of image acquisition, but also makes equipment maintenance more convenient, enabling quick replacement and adjustment of its position, thus improving the reliability and ease of maintenance of the system.

[0047] In this embodiment, the imaging structure 210 and the supplementary lighting structure 220 are electrically connected to the control system and operated by commands from the control system. This design allows the control system to adjust the parameters of the imaging structure 210 and the brightness of the supplementary lighting structure 220 in real time as needed, thereby optimizing image quality.

[0048] In this embodiment, the imaging structure 210 includes a third support rod 211 and a CCD camera 212. The third support rod 211 is vertically and detachably mounted within the accommodating cavity of the worktable 100. This not only ensures the stability of the imaging structure 210 during installation but also facilitates quick assembly and disassembly as needed. The CCD camera 212 is movably connected to the third support rod 211 via a mounting plate 213 and can move up and down along the length of the third support rod 211, allowing for height adjustment. This layout enables precise adjustment of the CCD camera 212's position as required, thereby altering its straight-line distance to the second conveyor belt 410. Adjusting the height of the CCD camera 212 optimizes the shooting angle and field of view, ensuring the acquisition of the clearest and most accurate image data. Furthermore, this design allows the system to adapt to objects of different sizes and heights, enhancing the system's versatility and application range.

[0049] Preferably, in this embodiment, two sets of third support rods 211 are provided, arranged side by side, and mounting plates 213 are movably connected to the ends of the two sets of third support rods 211, with the CCD camera 212 located between the two sets of third support rods 211. This design further ensures the reliable installation and stable operation of the CCD camera 212.

[0050] like Figure 2 , Figure 4 As shown, in this embodiment, the supplementary lighting structure 220 includes a fourth support rod 221 and a supplementary lighting plate 222. The fourth support rod 221 is vertically and detachably mounted within the accommodating cavity of the worktable 100, ensuring the stability of the supplementary lighting structure 220 installation and facilitating quick assembly and disassembly as needed. The supplementary lighting plate 222 is rectangular, horizontally positioned below the CCD camera 212, and has a through-hole for the light from the CCD camera 212 to pass through. This design not only provides uniform illumination for the subject but also avoids shadows or reflections caused by direct light sources. The supplementary lighting plate 222 is movably connected to the fourth support rod 221 via a grooved plate 223 and can move up and down along the length of the fourth support rod 221, allowing for height adjustment. When adjusting the height of the supplementary lighting plate 222, the linear distance between the supplementary lighting plate 222 and the second conveyor belt 410 can be adjusted according to the specific needs of the subject, thereby optimizing the light intensity and angle. This layout greatly enhances the system's flexibility and adaptability, ensuring ideal lighting effects under different shooting conditions.

[0051] Preferably, in this embodiment, the fourth support rod 221 is provided in four sets, arranged symmetrically in pairs, and the groove plate 223 is also provided in four sets, corresponding one-to-one with the fourth support rod 221 and forming a movable connection. The fill light plate 222 is detachably snapped onto the four groove plates 223. This design ensures the stability of the fill light plate 222 and the convenience of its assembly and disassembly.

[0052] Preferably, in this embodiment, both the third support rod 211 and the fourth support rod 221 are threaded rods.

[0053] In this embodiment, the sensing component 300 includes a first sensing structure 310 and a second sensing structure 320 electrically connected to the control system, with the first sensing structure 310 and the second sensing structure 320 located at opposite ends of the detection area. When the first sensing structure 310 detects that the workpiece has entered the detection area, it sends an electrical signal to the control system. The control system then triggers the CCD camera 212 to take a picture based on the electrical signal and controls the first conveyor belt 400 to stop rotating. When the second sensing structure 320 detects that the workpiece has left the detection area, it sends an electrical signal to the control system. The control system then drives the first conveyor belt 400 to continue rotating based on the electrical signal. By monitoring the workpiece's entry and exit from the detection area using the first sensing structure 310 and the second sensing structure 320 respectively, the system can control the start and stop of the first conveyor belt 400 according to the needs of different stages, further improving the automation level and safety of the detection process.

[0054] The first sensing structure 310 and the second sensing structure 320 are reflective grating sensors or other similar high-precision sensing devices, such as photoelectric sensors, inductive proximity sensors, capacitive proximity sensors, and laser rangefinders, to ensure accurate and reliable detection of the target object. Preferably, in this embodiment, both the first sensing structure 310 and the second sensing structure 320 are reflective grating sensors.

[0055] In this embodiment, the first sensing structure 310 is horizontally movably disposed above the first gap 600, and the second sensing structure 320 is horizontally movably disposed above the second gap 610. This design allows the positions of the first sensing structure 310 and the second sensing structure 320 to be adjusted as needed, while also improving the convenience of disassembly, assembly, and maintenance of the first sensing structure 310 and the second sensing structure 320.

[0056] In this embodiment, the first sensing structure 310 includes a first support rod 311 and a first sensing element 312. The first support rod 311 is horizontally positioned above the first conveyor belt 400, detachably connected to the frame 110, and extends towards the second sensing element 322. This design not only ensures the stability of the structure but also facilitates quick assembly and disassembly according to actual needs. The first sensing element 312 is movably and vertically connected to the first support rod 311 via a first fixing seat 313 and can move along the length of the first support rod 311. The first sensing element 312 extends along the length of the first gap 600 and adapts to the length of the first gap 600. This design not only allows for fine-tuning of the first sensing element 312 but also ensures that the first sensing element 312 can cover the entire length of the first gap 600, thereby achieving comprehensive detection.

[0057] In this embodiment, the second sensing structure 320 includes a second support rod 321 and a second sensing element 322. The second support rod 321 is horizontally positioned above the second conveyor belt 410, detachably connected to the frame 110, and extends towards the first sensing element 312. This design not only ensures the stability of the structure but also facilitates quick assembly and disassembly according to actual needs. The second sensing element 322 is movably and vertically connected to the second support rod 321 via a second fixing seat 323 and can move along the length of the second support rod 321. The second sensing element 322 extends along the length of the second gap 610 and adapts to the length of the second gap 610. This design not only allows for fine-tuning of the second sensing element 322 but also ensures that the second sensing element 322 can cover the entire length of the second gap 610, thereby achieving comprehensive detection.

[0058] In summary, the first sensing structure 310 and the second sensing structure 320 work together to ensure seamless detection throughout the production line. The relative position and angle of the two sensing structures can be adjusted according to actual needs, improving the overall performance of the system.

[0059] like Figure 1 As shown, in this embodiment, the control system is designed to achieve efficient and accurate automated detection and operation. It includes an industrial control computer 700 with built-in vision inspection programs, and the industrial control computer 700 is located on the side of the workbench 100 facing the operator. This layout not only improves the convenience of human-machine interaction but also facilitates quick access to and adjustment of system settings.

[0060] In this embodiment, the industrial control computer 700 is electrically connected to the imaging component 200, the sensing component 300, and the workpiece conveyor belt, respectively, realizing precise control of each component, ensuring the efficient and stable operation of the entire system. Specifically, when the workpiece enters the detection range of the first sensing structure 310, the sensing component 300 detects the presence of the workpiece and sends a signal to the industrial control computer 700 after the entire workpiece enters the detection area. After receiving the signal from the first sensing structure 310, the industrial control computer 700 immediately triggers the CCD camera 212 to take a picture, and the first conveyor belt 400 stops running. After the CCD camera 212 captures a high-definition image of the workpiece, it transmits it back to the industrial control computer 700. During this process, the second conveyor belt 410 continuously moves the workpiece slowly, taking dynamic pictures from multiple angles. The vision inspection program built into the industrial control computer 700 analyzes the received images in real time, identifying key features such as the shape, size, and surface defects of the workpiece riveting. If any non-compliance is found, the system will mark the workpiece. Based on the visual inspection results, the industrial control computer 700 adjusts the conveyor belt speed or stops the conveyor belt via the motor driver. For example, if the riveting quality of the workpiece is detected as acceptable, the workpiece will continue to move along the second conveyor belt 410 and the third conveyor belt 420 to enter the next process. If the riveting quality of the workpiece is detected as unacceptable, the conveyor belt will stop after the workpiece is removed from the inspection area, and an alarm structure will be used to remind the operator to handle the unacceptable workpiece in a timely manner.

[0061] Preferably, the industrial control computer 700 is equipped with an intuitive human-machine interface (HMI), allowing operators to view the system's operating status, real-time images, and detection results via a touchscreen or external monitor. Furthermore, parameter settings and system debugging can be performed through the interface.

[0062] In this embodiment, an alarm structure electrically connected to the control system is also provided. This alarm mechanism includes an indicator light 800 and a buzzer (not shown in the figure) located on the top of the workbench 100. The alarm structure consisting of the indicator light 800 and the buzzer can immediately sound an alarm when a defective product is detected, reminding the operator to take timely measures to prevent defective products from flowing into subsequent processes, thereby improving the safety and reliability of the production line.
