[0002] In modern automobile manufacturing, the accuracy of hole positions in components directly affects the assembly quality and operational performance of the entire vehicle. For example, excessive deviation in the hole position of a part can lead to assembly difficulties, poor sealing, or insufficient structural strength. Therefore, the development and use of precise and efficient hole position detection devices are crucial. A precise and efficient hole position detection device for automotive components is a device or system used to detect the positional accuracy and dimensions of holes (such as bolt holes and mounting holes) on automotive components. It is widely used in the automotive manufacturing industry, especially in quality control and production processes, to ensure the accurate shaping of components. These devices typically combine optical, mechanical, electronic, and computer technologies to achieve automated detection.

[0003] Advanced sensors (such as laser sensors and vision sensors) and measurement algorithms are typically used to ensure that the size and position errors of the holes are within acceptable limits. Automation technologies (such as robot operation and automated loading / unloading systems) enable rapid inspection to meet the needs of large-scale production. In addition to detecting hole positions, other geometric features, such as flatness and roundness, can also be checked simultaneously. The original position of the parts has a significant impact on the efficiency and accuracy of image recognition. Utility Model Content

[0028] Reference Figures 1 to 5 In one embodiment of this utility model, a precise and efficient detection device for the hole positions of automotive parts is provided. The automotive part 010 is generally bowl-shaped and has multiple fixing holes 011 on its outer periphery, including:

[0029] Conveyor line 100 is used to transport the automotive component 010;

[0030] A testing unit 200 is disposed on the side of the conveyor line 100. The testing unit 200 includes a vibration table 210, a testing barrel 220, a sample tray 230, and a camera 240. The testing barrel 220 is mounted on the vibration table 210, and the sample tray 230 is mounted on the top of the testing barrel 220. The upper surface of the sample tray 230 is provided with a groove structure corresponding to the automotive part 010. A gap 231 is formed between the sample tray 230 and the testing barrel 220 to avoid the fixing hole 011. The vibration table 210 is annular and surrounds a working space. The camera 240 is disposed in the working space and is aligned with the sample tray 230 and the gap 231. When the automotive part 010 is located inside the sample tray 230, the fixing hole 011 is located in the gap 231.

[0031] The transfer unit 300 includes a first linear drive 310 and a second linear drive 320 disposed on the first linear drive 310. The first linear drive 310 drives the second linear drive 320 to transfer between the conveyor line 100 and the test unit 200. The bottom of the second linear drive 320 is driven by a first suction cup 321.

[0032] A negative pressure source is connected to the first suction cup 321 to provide negative pressure.

[0033] In existing technologies, the original position of components has a significant impact on the efficiency and accuracy of image recognition.

[0034] The present invention provides a precise and efficient detection device for hole positions in automotive parts, comprising:

[0035] The conveyor line 100 is used to transport the automotive component 010. The form of the conveyor line 100 can be varied, such as a conveyor belt, to complete the transport process of the automotive component 010.

[0036] A testing unit 200 is located to the side of the conveyor line 100. The testing unit 200 includes a vibration table 210, a testing barrel 220, a sample tray 230, and a camera 240. The testing barrel 220 is mounted on the vibration table 210, so that the vibration of the vibration table 210 drives the testing barrel 220 to vibrate. The sample tray 230 is mounted on top of the testing barrel 220, and its upper surface has a groove structure corresponding to the automotive part 010. The sample tray 230 vibrates along with the testing barrel 220, thereby allowing the automotive part 010 in the sample tray 230 to overcome friction and other resistance and accurately position itself in the groove structure. A gap 231 is formed between the sample tray 230 and the testing barrel 220 to avoid the fixing hole 011. The vibration table 210 is annular and surrounds a working space, and the camera 240 is located within this working space. The camera 240 is aligned with the sample tray 230 and the gap 231. When the automotive component 010 is located within the sample tray 230, the fixing hole 011 is located within the gap 231. The image data obtained by the camera 240 is compared with a standard image to evaluate the position of the fixing hole 011. In particular, when obtaining image information, the bottom structure of the sample tray 230 can be simplified to avoid information errors caused by raising the working content of the camera 240. The camera 240 can obtain visible light images or infrared images, without limitation.

[0037] The transfer unit 300 includes a first linear drive 310 and a second linear drive 320 disposed on the first linear drive 310. The first linear drive 310 can be a linear drive motor or a lead screw drive, etc. The second linear drive 320 can be an electric push rod or a pneumatic push rod, etc. The first linear drive 310 drives the second linear drive 320 to transfer between the conveyor line 100 and the testing unit 200, thereby completing the transfer of automotive parts 010 (including transferring untested parts from the transfer unit 300 to the sample tray 230, and transferring tested parts back to the transfer unit 300). The bottom telescopic drive of the second linear drive 320 has a first suction cup 321, thereby performing a suction action. The operation of the transfer unit 300 and the testing unit 200 can be completed by a preset program in a microcontroller, or by real-time detection and control through corresponding sensors, or a combination of both control methods.

[0038] A negative pressure source is connected to the first suction cup 321 to provide negative pressure.

[0039] In summary, a gap 231 is formed between the sample tray 230 and the test barrel 220 to avoid the fixing hole 011. When the automotive part 010 is located in the sample tray 230, the fixing hole 011 is located in the gap 231. The vibration of the vibration table 210 transmits the vibration of the sample tray 230, which vibrates along with the vibration of the test barrel 220. This allows the automotive part 010 in the sample tray 230 to overcome friction and other resistance and accurately enter the accurate position of the groove structure. The camera 240 is aligned with the sample tray 230 and the gap 231. The image data obtained by the camera 240 is compared with the standard image to evaluate the position of the fixing hole 011.

[0040] In one embodiment, the bottom of the second linear drive 320 is also telescopically driven with a second suction cup, and the first suction cup 321 and the second suction cup are spaced apart in the width direction of the conveyor line 100.

[0041] In this embodiment, a second suction cup is added to improve the efficiency of picking up and putting down materials. For example, the first suction cup 321 and the second suction cup can pick up an automotive part 010 to be tested and a part that has been tested, respectively, which can reduce the workload of the first linear drive 310 and improve its work efficiency.

[0042] In one embodiment, the camera 240 is an infrared type.

[0043] In this embodiment, the camera 240 is limited to an infrared type, thereby reducing the focusing requirements. In particular, when the camera 240 is an infrared type, a heating mechanism can be set up to heat the automotive part 010 to be tested.

[0044] In one embodiment, a heater is disposed above the conveyor line 100.

[0045] In this embodiment, the heating of the automotive parts 010 on the conveyor line 100 is achieved by the operation of a heater, thereby providing a basis for the camera 240 to collect infrared signals. The type of heater is not limited; it can be an infrared heater.

[0046] In one embodiment, the sample tray 230 is provided with a through hole.

[0047] In this embodiment, in addition to the fixing hole 011, the automotive component 010 is also provided with a central fixing hole. The central fixing hole is located through the through hole on the sample plate 230, so the camera 240 can test not only the circumferential fixing hole 011, but also the central fixing hole.

[0048] In one embodiment, the sample tray 230 is detachably mounted on the test barrel 220.

[0049] In this embodiment, the replaceability of the sample tray 230 enables adaptation to different models of automotive parts 010. The sample tray 230 can be fixed to the test barrel 220 in various ways, such as snap-fit, clip-fit, or screw connection.

[0050] Reference Figure 2 In one embodiment, the conveyor line 100 is a conveyor belt type.

[0051] In this embodiment, a relatively convenient and mature conveying method is presented. The conveyor belt type conveyor line 100 has high debugging flexibility and can convey various models and sizes of automotive parts 010.

[0052] Reference Figure 2 In one embodiment, baffles are provided on both sides of the conveyor line 100 in the width direction.

[0053] In this embodiment, while restricting the falling of the automotive component 010 by using a baffle, the placement position of the automotive component 010 can also be restricted.

[0054] In one embodiment, the first linear drive 310 is a lead screw type, and the second linear drive 320 is a pneumatic rod type.

[0055] In this embodiment, the types of the first linear drive 310 and the second linear drive 320 are limited. The first linear drive 310 is a lead screw type, which has the advantages of stability, accuracy, simplicity, and high structural strength; its specific structure refers to the current lead screw drive structure. The second linear drive 320 is a pneumatic rod type, which has the advantages of simplicity and convenience; its specific structure refers to the current pneumatic push rod structure.

[0056] In one embodiment, the negative pressure source drives the second linear drive 320.

[0057] In this embodiment, the driving source of the second linear drive 320 is set as a negative pressure source, thereby avoiding the need to introduce other mechanisms.

[0058] In summary, the present invention provides a precise and efficient hole position detection device for automotive parts. A gap 231 is formed between the sample tray 230 and the test barrel 220 to avoid the fixing hole 011. When the automotive part 010 is located within the sample tray 230, the fixing hole 011 is located within the gap 231. The vibration of the vibration table 210 transmits vibration to the sample tray 230, causing it to vibrate along with the test barrel 220. This allows the automotive part 010 in the sample tray 230 to overcome friction and other resistance and accurately position itself into the groove structure. The camera 240 is aligned with the sample tray 230 and the gap 231. The image data obtained by the camera 240 is compared with a standard image to evaluate the position of the fixing hole 011.
