Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lighting sources, and in particular to a composite light source device that is rotatable, allows for synchronous upper and lower workstations, and provides multimodal lighting. Background Technology
[0002] In industrial visual inspection, the use of light source devices to inspect workpieces with complex curved surfaces or three-dimensional features (such as mobile phone camera modules, spherical connectors, tilted nameplates, etc.) faces significant challenges and suffers from the following shortcomings:
[0003] 1) Fixed angle of light source device, resulting in blind spots in illumination: A fixed angle light source device cannot illuminate certain angles and areas of complex curved surfaces or three-dimensional features. There will always be some areas that are dark due to the reflection angle, leading to missed defects.
[0004] 2) The light source device can detect multiple items, which will result in a large space occupied by the light source device, thus making the light source device not small enough and having poor adaptability: At present, there are two main lighting methods for light source devices. The first is that the light source device illuminates and detects each item individually. The second is that multiple light source devices are set up and multiple light source devices illuminate multiple items in parallel. However, multiple light source devices will result in a large space occupied and poor adaptability, and are not suitable for installation in small spaces.
[0005] 3) The light source device faces the challenge of imaging multiple features: A workpiece often has multiple features to be detected simultaneously, such as QR codes on the surface (requiring diffuse flat light), scratches on smooth curved surfaces (requiring low-angle diffuse light), and the dimensions of three-dimensional structures (requiring perpendicular parallel light). Traditional light source devices require multiple light sources and detection from different workstations, which is inefficient and has positioning errors.
[0006] 4) The problems mentioned in 1), 2), and 3) above are difficult to overcome at the same time. It is difficult to ensure that the light source device can simultaneously achieve rotation, synchronization of upper and lower work positions, and multi-modal illumination. It is also difficult to achieve more comprehensive and efficient detection of the object under test and more compact design. Utility Model Content

It occupies little space, making the composite light source device not only more efficient in detection, but also conducive to miniaturization design.
[0010] 3) The upper and lower sides of the rotating mounting bracket are designed with integrated point light sources and ring light sources to achieve multimodal illumination, which is suitable for multi-feature imaging of the object under test and provides more comprehensive detection;

[0049] An embodiment of this utility model provides a rotatable, synchronously operating, and multimodal illumination composite light source device, which has the following advantages:
[0050] 1. This utility model is provided with a rotating mounting frame 3. By adjusting the tightness of the bolts at both ends of the rotating mounting frame 3, it can rotate at a certain angle between the first support frame 1 and the second support frame 2, so that a certain irradiation angle and area of the object to be tested can be detected, thereby avoiding the formation of dark areas due to reflection angle problems, thus avoiding the omission of some defects in the area of the object to be tested, and thus ensuring more comprehensive detection.
[0051] 2. The rotating mounting frame 3 of this utility model has a first mounting cavity 31 on its upper side and a second mounting cavity 32 on its lower side. The first mounting cavity 31 is provided with a first point light source 4 and a first ring light source 5, and the second mounting cavity 32 is provided with a second point light source 7 and a second ring light source 8, thereby realizing the simultaneous detection of the upper detection station 6 and the lower detection station 9. Therefore, this utility model can realize the detection of the upper and lower stations through the first mounting cavity 31 on the upper side and the second mounting cavity 32 on the lower side of the rotating mounting frame 3. It not only has the advantages of higher detection efficiency, but also has the advantages of small space occupation, which is conducive to miniaturization design and better adaptability.
[0052] 3. The upper side of the rotating mounting bracket 3 of this utility model realizes multimodal illumination (three modes of illumination: vertical parallel light, low-angle diffuse light, and diffuse parallel light formed by vertical parallel light + low-angle diffuse light) of the object to be tested on the upper detection station 6 through the first point light source 4 and the first ring light source 5. The lower side of the rotating mounting bracket 3 realizes multimodal illumination of the object to be tested on the lower detection station 9 through the second point light source 7 and the second ring light source 8. It is suitable for multi-feature imaging of the object to be tested, with higher detection efficiency, more comprehensive detection, and smaller space occupation.
[0053] The optical principles of the combination of the first point light source 4 and the first ring light source 5, and the combination of the second point light source 7 and the second ring light source 8, are as follows:
[0054] First, the first point light source 4 can emit point light through the first point light LED component 41. The first point light collimating lens 43 receives the point light and converts it into parallel light. The first magnifying collimating lens 45 converts the parallel light into more uniform and wider-range parallel light. The first point light source 4 can be used to emit parallel light alone for detecting the object under test (such as detecting the three-dimensional structural dimensions, scratches in flat areas, and prominent mirror surfaces).
[0055] Secondly, the first ring light source 5 can emit low-angle diffused light individually through several first LED beads on the first ring PCB board 53 for detecting the object under test (such as detecting scratches on a smooth curved surface).
[0056] Finally, the first point light source 4 and the first ring light source 5 can be combined to emit light to form diffuse flat light for detecting the object to be tested (such as detecting QR codes on a surface, where the first point light source 4 highlights key feature contours, and the first ring light source 5 supplements ambient light, reduces overall contrast, avoids overexposure or excessive shadows, and obtains the most detailed image).
[0057] Similarly, the optical principle of the combination of the second point light source 7 and the second ring light source 8 is the same.
[0058] 4. In summary, the present invention provides a rotatable, synchronous upper and lower workstation, and multimodal illumination composite light source device. This device combines rotatable angle illumination, synchronous upper and lower workstation illumination, and multimodal illumination. Through a single installation and rotation process, and by rapidly switching illumination modes electronically, multiple images of the same object under test can be obtained at different angles and under different illumination modes. This greatly enriches the feature information, meets the needs of multi-feature simultaneous detection, enhances defect contrast with directional illumination, and allows for the beam of the composite light source device to be aligned with the direction of the scratch for directional defects (such as unidirectional machining lines or scratches) by rotating the device at a certain angle. Therefore, the composite light source device has a more compact structure, is more suitable for miniaturization design, and has higher and more comprehensive detection efficiency.
[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
