Description

Technical Field

[0001] This utility model relates to the field of inspection lens technology, and more specifically, to a multispectral inspection lens module. Background Technology

[0002] Currently, in the process of industrial product inspection, inspection robots with inspection lenses are often used for automatic inspection. Existing inspection lenses, with their single-band vision systems (such as ordinary visible light), often cannot detect all types of defects. For example, defects such as scratches, oil stains, and oxidation show huge differences in imaging performance under different spectra (such as ultraviolet UV, infrared IR, and visible light). Therefore, it is often necessary to use multispectral inspection lens modules for inspection work.

[0003] However, existing technologies have some problems: Although existing multispectral inspection lens modules can take pictures and images under different spectra and discover different types of defects, in actual use, existing multispectral inspection lens modules usually use multiple independent cameras with different filters or lenses, which is costly, complex in collaborative calibration, and has low switching efficiency. Moreover, the switching process usually requires manual intervention or complex mechanical actions, which is inefficient. When the lens needs to be cleaned or replaced, the process is cumbersome, which affects the overall efficiency of the equipment. Therefore, we propose a multispectral inspection lens module.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] like Figures 1-5As shown, the multispectral inspection lens module includes a base 1, a housing 2 fixedly mounted on the base 1, a photosensitive plate 3 disposed on the housing 2, a disc 4 rotatably connected to the housing 2, and a lens body 5 movably inserted into the disc 4. At least three sets of lens bodies 5 are provided. The disc 4 and the base 1 are also connected by a drive component. The drive component enables the disc 4 to rotate to adjust different lens bodies 5 to the position of the photosensitive plate 3. A ring 6 is fixedly fitted on the outer surface of the lens body 5. The ring 6 and the disc 4 are connected by a limiting component. The lens body 5 can be installed and removed from the disc 4 by the limiting component.

[0029] The module is installed on the inspection robot and controlled by the main controller. The industrial camera is set inside the housing 2 and is light-sensitive through the photosensitive plate 3. When the operator needs to adjust different lens bodies 5 to the position of the photosensitive plate 3 for video inspection, the drive component can rotate the disk 4 to adjust the required lens body 5 to the position of the photosensitive plate 3. When the operator needs to remove the lens body 5 for inspection and maintenance, the limiting component can be used to complete the quick disassembly and assembly, thereby improving the overall efficiency of use.

[0030] The aforementioned multispectral inspection lens module includes a drive component comprising a stepper motor 7, which is fixedly mounted on a base 1. The output shaft of the stepper motor 7 is connected to a rotating shaft 8 via a coupling. A drive gear 9 is fixedly sleeved on the rotating shaft 8. A driven gear ring 10 is fixedly sleeved on the outer surface of the disc 4, and the driven gear ring 10 is meshed with the drive gear 9.

[0031] By activating the stepper motor 7, the staff can cause the rotating shaft 8 to drive the drive gear 9 to rotate, which in turn causes the driven gear ring 10 to drive the disc 4 to rotate. This allows the lens body 5 to be adjusted to the position of the photosensitive plate 3, enabling the imaging of different defects under different spectra as needed. This high switching efficiency improves work efficiency.

[0032] The aforementioned multispectral inspection lens module includes a limiting component comprising a block 11, which is fixedly mounted on a disc 4. A plate 12 is movably inserted into the block 11. Side grooves 24 are provided on both sides of the ring 6. One end of the plate 12 is movably inserted into the side groove 24. An oblique hole 13 is provided on the plate 12. An arc-shaped rod 14 is movably mounted on the disc 4. A circular block 15 located inside the oblique hole 13 is fixedly mounted on the arc-shaped rod 14.

[0033] By pulling the arc rod 14, the staff can move the circular block 15, causing the outer surface of the circular block 15 to press against the inner wall of the oblique hole 13, thereby causing the two insert plates 12 to move in opposite directions, so that the insert plates 12 can be pulled out from the side groove 24, thereby releasing the restriction on the lens body 5, and the lens body 5 can be removed.

[0034] The aforementioned multispectral inspection lens module has a guide rod 16 fixedly connected to the arc rod 14, and a positioning block 17 movably sleeved on the outer surface of the guide rod 16. The positioning block 17 is fixedly installed on the disc 4.

[0035] The design of the guide rod 16 can provide good guidance for the arc rod 14, making it more stable when the staff pulls the arc rod 14.

[0036] In the aforementioned multispectral inspection lens module, a spring 18 is movably sleeved on the outer surface of the guide rod 16, and the two ends of the spring 18 are respectively fixedly connected to the arc-shaped rod 14 and the positioning block 17.

[0037] By setting the spring 18 to a compressed state, the elastic force of the spring 18 will cause the arc rod 14 to tend to move closer to the lens body 5, thereby causing the two insert plates 12 to tend to move towards each other. This will allow one end of the insert plate 12 to be stably kept inside the side groove 24, maintaining the limiting effect on the lens body 5.

[0038] In the aforementioned multispectral inspection lens module, the diameter of the circular block 15 is matched with the width of the oblique hole 13, and the inner wall of the oblique hole 13 is coated with a lubricating layer.

[0039] The aforementioned multispectral inspection lens module has a first magnet ring 19 fixedly mounted on the disc 4 and a second magnet ring 20 adapted to the first magnet ring 19 fixedly mounted on the ring 6. The magnetic poles of the opposite sides of the first magnet ring 19 and the second magnet ring 20 are opposite.

[0040] The design of the first magnet ring 19 and the second magnet ring 20 allows for the initial positioning of the lens body 5 during installation, thanks to the attraction between the first magnet ring 19 and the second magnet ring 20, which facilitates subsequent installation of the lens body 5.

[0041] The aforementioned multispectral inspection lens module has a round rod 21 fixedly mounted on the first magnet ring 19, with the other end of the round rod 21 passing through the round ring 6.

[0042] The design of the round rod 21 can further limit the lens body 5 to prevent it from rotating after being attracted and installed, thus further facilitating subsequent limiting and installation work.

[0043] The aforementioned multispectral inspection lens module has a position sensor 22 fixedly mounted on the disc 4. Both the position sensor 22 and the stepper motor 7 are electrically connected to the main controller.

[0044] The position sensor 22 is used to detect the initial position of the disk 4, ensuring that the main controller can accurately know which lens is currently located on the photosensitive plate 3, so as to control the stepper motor 7 to remain stationary or rotate for adjustment.

[0045] The aforementioned multispectral inspection lens module has a protective plate 23 fixedly installed on the disc 4, and the width of the protective plate 23 is the same as the width of the disc 4.

[0046] The design of the protective plate 23 allows for the shielding and protection of the unused lens body 5.

[0047] Working principle and usage process of this utility model:

[0048] In use, when staff need to adjust the positions of different lens bodies 5 to the photosensitive plate 3 for video inspection, the staff activates the stepper motor 7 via the main controller. This causes the rotating shaft 8 to drive the drive gear 9, which in turn causes the driven gear ring 10 to drive the disk 4. The position sensor 22 detects the position of the disk 4, ensuring that the main controller accurately knows which lens is currently located on the photosensitive plate 3. This allows for the adjustment of the required lens body 5 to the position on the photosensitive plate 3, enabling the imaging of different defects under different spectral conditions as needed. This high switching efficiency improves performance. To improve work efficiency, when the lens body 5 needs to be removed for cleaning or maintenance, the operator can pull the arc rod 14 to move the round block 15, causing the outer surface of the round block 15 to press against the inner wall of the oblique hole 13. This causes the two insert plates 12 to move in opposite directions, allowing the insert plates 12 to be pulled out from the side groove 24, thereby releasing the restriction on the lens body 5. Then, the operator can hold the lens body 5 and pull it outward to overcome the attraction between the first magnet ring 19 and the second magnet ring 20 and remove the lens body 5, completing the quick disassembly and assembly, thus improving the overall efficiency of use.
