[0027] Example 1:

[0028] like Figure 1 and Figure 4As shown, this utility model provides a high-speed swing-arm vision system, including a fixed base 1, a swing-arm assembly 2, a drive assembly 3, a bearing assembly 4, and a vision inspection assembly 5. The drive assembly 3 is fixed to the upper end of the fixed base 1, and the bearing assembly 4 is fixed to the lower end of the fixed base 1, with the drive assembly 3 and bearing assembly 4 correspondingly arranged. The swing-arm assembly 2 is disposed between the drive assembly 3 and the bearing assembly 4, and is fixedly connected to the drive assembly 3 and movably connected to the bearing assembly 4. The drive assembly 3 is used to control the swing-arm assembly 2 to rotate about the axis of the bearing assembly 4. The vision inspection assembly 5 is fixed on the swing-arm assembly 2 and is used to inspect the product 6 to be tested that is conveyed on a circular conveying track around the fixed base 1. Specifically, the fixed base 1 has a certain rigidity and is used to provide a positional reference. A circular conveyor belt or conveyor disc is provided around the fixed base 1 to transport the product under test 6. The center of the conveyor belt or conveyor disc is on the axis of the drive assembly 3, and the conveying position of the conveyor belt or conveyor disc transporting the product under test 6 is located below the first end of the mounting rod 21 of the swing arm assembly 2. The product under test 6 can be evenly or non-uniformly arranged on the circular conveying trajectory. The drive assembly 3 and the bearing assembly 4 are respectively set at the upper and lower ends of the fixed base 1 and correspond to each other, which facilitates the cooperation between the drive assembly 3 and the bearing assembly 4 to support the swing arm assembly 2 and realize the control of the rotation of the swing arm assembly 2, thereby adjusting the position of the vision detection component 5 on the swing arm assembly 2, improving the degree of freedom of the vision system, and enabling the vision system to capture the product under test 6 at any position.

[0029] This invention uses the cooperation of the drive component 3 and the isometric component to control the rotation of the swing arm component 2, thereby adjusting the position of the vision inspection component 5 on the swing arm component 2, improving the degree of freedom of the vision system, and enabling the vision inspection component 5 to perform visual inspection on the product under test 6 at any position on the circular conveyor track around the vision system, or to take multiple pictures or follow-up pictures of the same product under test 6, so as to meet the different inspection needs of users.

[0030] As an optional implementation method, such as Figure 2As shown, the drive assembly 3 includes a transmission component 31, a drive component 32, and a mounting plate 33. The drive component 32 is fixed on the mounting plate 33, which is fixedly connected to the upper end of the fixed base 1. One end of the transmission component 31 is movably connected to the drive component 32, and the other end is fixedly connected to the swing arm assembly 2. Specifically, the mounting plate 33 is used to mount and fix the drive component 32 on the upper end of the fixed base 1. The drive component 32 is movably connected to the transmission component 31, and the drive component 32 can control the rotation of the transmission component 31, thereby controlling the swing arm assembly 2 connected to the transmission component 31 to move synchronously and adjust the position of the swing arm assembly 2. This allows the vision inspection component 5 on the swing arm assembly 2 to perform multiple image inspections or follow-up image inspections on the product 6 under test, enabling the vision system to image the product 6 under test at any position on the circular conveyor track around the fixed base 1, thus improving the degree of freedom of the vision system. The drive component 32 can be selected as a direct-drive rotary motor or a servo motor, and the transmission component 31 is a reducer. The drive component 32 is preferably a servo motor, and the transmission component 31 is preferably a ramp reducer.

[0031] As an optional implementation method, such as Figure 1 As shown, the bearing assembly 4 includes a bearing component 41 and a mounting base 42. The bearing component 41 is fixed on the mounting base 42, which is fixedly connected to the lower end of the fixed base 1. The axis of the bearing component 41 is on the same axis as the center of the transmission component 31. Specifically, the bearing component 41 is fixed to the lower end of the fixed base 1 via the mounting base 42, corresponding to the drive assembly 3. A through hole structure 544 is provided in the middle of the bearing component 41. Through the through hole structure 544, it is clearance-fitted with the swing arm assembly 2, allowing the drive assembly 3 to control the swing arm assembly 2 to rotate around the axis containing the axis of the bearing component 41 and the center of the transmission component 31. The bearing assembly 4 is used to support the swing arm assembly 2 and ensure the stability of the structure.

[0032] As an optional implementation method, such as Figure 2As shown, the swing arm assembly 2 includes a mounting rod 21, a fixing rod 22, and a connecting member 23. The lower end of the fixing rod 22 is fixedly connected to the first end of the connecting member 23. The second end of the connecting member 23 passes through the inner ring hole of the bearing component 41, and the second end of the connecting member 23 is clearance-fitted with the inner ring hole of the bearing component 41. The upper end of the fixing rod 22 is fixedly connected to the mounting rod 21, and the mounting rod 21 is fixedly connected to the transmission component 31. Specifically, the fixing rod 22 is movably connected to the bearing component 41 through the connecting member 23. After the drive assembly 3 is started, it can drive the connecting member 23 to rotate within the inner ring hole of the bearing component 41, thereby limiting and supporting the swing arm assembly 2 through the bearing component 41. The fixing rod 22 is located at one end of the mounting rod 21. The fixing rod 22 is a solid structure used for configuration, improving rigidity, and ensuring the stability of the structure. Mounting rod 21 includes a first mounting component and a second mounting component. The second mounting component is fixed to the side of the first mounting component. One end of the first mounting component is fixedly connected to the upper end of the fixing rod 22, and the middle part of the first mounting component is fixedly connected to the transmission component 31 to ensure the stability of mounting rod 21. The first mounting component is used to fix the camera 51 of the vision inspection assembly 5 (as described below), and the second mounting component is used to fix the lens 52, the emitting prism, and the light source module 54 of the vision inspection assembly 5.

[0033] As an optional implementation method, such as Figure 2 As shown, the fixed base 1 is provided with a groove 11, which is used to accommodate the fixed rod 22. Specifically, in this embodiment, the fixed base 1 can be provided with the groove 11 on the side of the fixed base 1 according to the actual situation of the swing arm assembly 2. The groove 11 is located on the same side of the fixed base 1 as the drive assembly 3 and the bearing assembly 4, so as to provide the fixed rod 22 of the swing arm assembly 2 with a space for movement when the drive assembly 3 drives the swing arm assembly 2 to rotate. The size of the groove 11 is adaptively set according to the actual situation. The groove 11 matches the fixed rod 22 and can accommodate the fixed rod 22.

[0034] As an optional implementation method, such as Figure 1 As shown, the visual inspection component 5 includes a camera 51, a lens 52, a reflecting prism 53, and a light source module 54. The camera 51, lens 52, and reflecting prism 53 are sequentially fixed on the mounting rod 21, and are on the same horizontal line. The light source module 54 is fixed on the first end of the mounting rod 21, and is positioned below the reflecting prism 53. Specifically, the light source module 54 is positioned corresponding to the circular conveyor track. When the visual inspection component 5 inspects the product 6 under test, the light source module 54 illuminates the product 6 below it. The product 6 under test reflects the light emitted by the light source module 54 to the reflecting prism 53, which then reflects it to the lens 52. The lens 52 focuses the light and reflects it back to the camera 51, allowing the camera 51 to acquire the visual image information of the product 6 under test, thereby achieving visual inspection of the product 6 under test.

[0035] As an optional implementation, the reflecting prism 53 is a right-angle prism. The first right-angle face of the reflecting prism 53 is on the same horizontal line as the camera 51 and the lens 52, and the second right-angle face of the reflecting prism 53 is on the same axis as the light source module 54. Specifically, the horizontal line where the camera 51, lens 52, and reflecting prism 53 are located is perpendicular to the axis where the reflecting prism 53 and the light source module 54 are located. The light source illuminating the product under test 6 from the light source module 54 is reflected by the product under test 6 onto the inclined surface of the right-angle prism. The light then undergoes total internal reflection on the first right-angle face through the inclined surface of the right-angle prism, and a second total internal reflection occurs through the second right-angle face. Finally, the light is reflected out to the lens 52 and the camera 51 in the opposite direction to the incident direction through the inclined surface of the right-angle prism.

[0036] As an optional implementation method, such as Figure 3 As shown, the light source module 54 includes a substrate 541, a flashing plate 542, and multiple LED beads 543. Both the substrate 541 and the flashing plate 542 are fixed to the first end of the mounting rod 21, with the substrate 541 positioned above the flashing plate 542 and spaced apart. The substrate 541 and the flashing plate 542 have corresponding through-hole structures 544, which correspond to the second right-angled surfaces of the reflecting prism 53. Multiple LED beads 543 are fixed to the periphery of the substrate 541 and are arranged adjacent to the flashing plate 542. Specifically, the substrate 541 is used to mount multiple LED beads 543. The substrate 541 is preferably an aluminum substrate, and the LED beads 543 are preferably LED beads. The multiple LED beads 543 are positioned around the through-hole structures 544 of the substrate 541, allowing for zoned illumination as needed. The flashing plate 542 is positioned below the substrate 541 and is used to adjust the flashing frequency, brightness, and color of the LED beads 543. Both the substrate 541 and the flashing plate 542 have through holes 544 in the middle, so that when the light source illuminating the product under test 6 is reflected by the lamp bead 543, it can be reflected to the reflecting prism 53 through the through holes 544. The visual information acquired by the camera 51 is obtained by the reflection of the reflecting prism 53, thereby completing the visual inspection of the product under test 6.
