[0002] In the field of high-end precision manufacturing and automated detection, machine vision systems are facing increasingly complex imaging challenges. The measured objects often have multiple characteristics, such as micron-level scratches, junctions of different materials, weak concave and convex fluctuations, and specific color contaminants, etc. These characteristics have different reflection and scattering properties of light.

[0003] Existing detection light sources are generally fixed light sources, such as ring light and bar light. The light path angle, spot size, and irradiation direction of the light source are usually fixed. When it is necessary to detect different properties of defects on the same workpiece, such as detecting edge profile and surface texture at the same time, multiple light sources need to be installed and triggered at different times, or the multiple light sources need to be moved and adjusted mechanically. This will result in a complex system, low efficiency, and cannot meet the beat and flexible production requirements of online high-speed detection. It also leads to inherent problems such as large size of light source detection equipment, poor repeatability of mechanical positioning, slow switching speed, and tedious light path calibration.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention provides a first optical path and a second optical path, which are independent of each other and integrated inside the mounting housing. The light is refracted by a first and second prism at the bottom, illuminating the surface of the object being measured. This allows the light to overlap on the object's surface. The difference in light intensity distribution created by the overlapping illumination effectively enhances the contrast of the object's surface features, thereby improving detection accuracy. Simultaneously, the first and second prisms can be angled via a rotating adjustment mechanism, allowing for flexible adjustment of the light refraction angle according to actual detection needs, ensuring precise coverage of the measured area by the overlapping area. Furthermore, by adjusting the light parameters in the first and second optical paths, such as light intensity and wavelength, adaptive detection of objects with different materials and surface characteristics can be achieved.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are one embodiment of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 9 This invention provides an integrated light source with adjustable multi-path parameters.

[0032] like Figure 1 andFigure 2 As shown, the integrated light source includes a mounting housing 1 at the top and a first side plate 12 and a second side plate 13 at the bottom of the mounting housing 1. The mounting housing 1 is an inverted cuboid with an internal cavity 2. A first light path 3 is mounted on the left side of the cavity 2, and a second light path 4 is mounted on the right side. The first light path 3 and the second light path 4 emit light downwards. A first triangular prism 6 is mounted at the bottom of the first light path 3, and the inclined surface of the first triangular prism 6 refracts the light from the first light path 3 onto the surface of the object 7 to be measured on the right. A second triangular prism 8 is mounted at the bottom of the second light path 4, and the inclined surface of the second triangular prism 8 refracts the light from the second light path 4 onto the same surface of the object 7 to be measured. This allows the light to overlap and illuminate the surface of the object under test 7. In this embodiment, the second light path 4 is the main illumination beam, and the first light path 3 is the auxiliary supplementary light beam. By adjusting the luminous intensity of the first light path 3 and the second light path 4, the synergistic optimization between the main illumination and the auxiliary supplementary light can be achieved, improving the uniformity and contrast of the illumination on the surface of the object under test 7. Furthermore, the illumination angle of the first light path 3 and the second light path 4 can also be adjusted. Specifically, the first triangular prism 6 and the second triangular prism 8 are respectively installed inside the rotating adjustment component 9. The rotating adjustment component 9 is used to adjust the slope angle of the first triangular prism 6 and the second triangular prism 8, thereby controlling the direction of light refraction and the position of the overlapping area.

[0033] Furthermore, the first prism 6 is used to adjust the refraction angle of the first light path 3 so that the light is precisely deflected for auxiliary illumination; the second prism 8 is used to adjust the refraction angle of the second light path 4 to achieve directional control of the main illumination beam.

[0034] The mounting housing 1 has an arc-shaped concave surface 11 inside. A first optical path 3 is installed on one side of the arc-shaped concave surface 11, and a second optical path 4 is installed on the other side. The first optical path 3 and the second optical path 4 emit light rays at an angle downwards, so that the light rays can reach different prism slopes without interfering with each other, thereby achieving precise overlap on the surface of the object being measured 7.

[0035] The first optical path 3 includes a first light-emitting plate 31 and a first light-concentrating rod 32 installed below the first light-emitting plate 31; the first light-concentrating rod 32 focuses the light emitted by the first light-emitting plate 31 onto the inclined surface of the first triangular prism 6. The first optical path 3 has only one first light-emitting plate 31, so it can be used as auxiliary lighting.

[0036] The second optical path 4 includes a second light-emitting plate 41, a third light-emitting plate 42, and a fourth light-emitting plate 43 arranged side by side. A second focusing rod 44, a third focusing rod 45, and a fourth focusing rod 46 are respectively installed below the second light-emitting plate 41, the third light-emitting plate 42, and the fourth light-emitting plate 43. Due to the curvature of the arc-shaped concave surface 11, which guides the direction of light propagation, the second focusing rod 44, the third focusing rod 45, and the fourth focusing rod 46 respectively converge the light from their respective light-emitting plates onto the inclined surface of the second triangular prism 8, concentrating and combining the beams from the three light-emitting plates into a main illumination beam. Through the coordinated operation of multiple light-emitting plates, the intensity of the main illumination beam is significantly improved. Simultaneously, with the precise optical control of the focusing rods and the triangular prism, a uniform and high-brightness illumination area is ensured on the surface of the object being measured. The rotating adjustment component 9 can finely adjust the angle of the inclined surface of the second triangular prism 8, achieving dynamic control of the overlapping position of the optical paths to adapt to different detection scenario requirements.

[0037] In this embodiment, four light-emitting plates are provided, thus forming four basic illumination channels. Guided by the arc-shaped concave surface 11, the four light-emitting plates form a multi-angle incident light field. The first light-emitting plate 31 independently serves as an auxiliary light source, while the second, third, and fourth light-emitting plates 41, 42, and 43 work together to form the main illumination system. Through each focusing rod and the corresponding prism bevel, the main beam and auxiliary beam achieve spatial overlap and intensity matching on the surface of the object under test 7, further improving imaging contrast and detection accuracy.

[0038] In this embodiment, the four light-emitting panels are editable in terms of light emission. Each panel has a high-power multi-color LED array on its surface. The switching, brightness, and color temperature of each LED unit can be independently adjusted via a control circuit, allowing the color of the light output from each panel to be independently adjustable to adapt to the optical response characteristics of different surface materials and achieve optimal imaging contrast. Through programming control, red, green, blue, and white light can be output sequentially or in combination, meeting diverse detection needs such as color imaging, surface defect identification, and three-dimensional morphology reconstruction, thus improving the system's adaptability and intelligence.

[0039] In this embodiment, the first light-emitting plate 31, the third light-emitting plate 42, and the fourth light-emitting plate 43 emit white light outwards, the second light-emitting plate 41 emits red and blue light outwards, and a diffuser plate 47 is installed at the lower part of the second focusing rod 44. The diffuser plate 47 uniformly diffuses the red and blue light, so that the red and blue light form a uniformly mixed illumination field on the surface of the object being measured. Furthermore, a filter 48 is installed at the lower part of the diffuser plate 47. In this embodiment, the filter 48 is a filter with a specific bandwidth. For example, a blue filter only allows the 450-470nm blue light band to pass through, effectively suppressing other stray light interference. Furthermore, the filter 48 is installed in the longitudinal adjustment component 49, which adjusts the longitudinal movement of the filter 48, allowing it to participate in or not participate in the filtering process of the red and blue light.

[0040] The mounting housing 1 is equipped with a first side plate 12 and a second side plate 13 at its lower part. A first triangular prism 6 is installed at the upper part between the first side plate 12 and the second side plate 13, and a second triangular prism 8 is installed at the lower part. Two rotating adjustment components 9 are also installed between the first side plate 12 and the second side plate 13. One rotating adjustment component 9 houses the first triangular prism 6, and the other rotating adjustment component 9 houses the second triangular prism 8. The two rotating adjustment components 9 are independently controlled and can independently adjust the deflection angles of the first triangular prism 6 and the second triangular prism 8, thereby precisely controlling the spatial overlap area and incident direction of the main beam and the auxiliary beam to adapt to the test surface with different curvatures and reflection characteristics. By coordinating the spectral output of the light-emitting plate and the angle configuration of the triangular prisms, dynamic reconstruction of the illumination field is achieved, further improving the identification capability of small defects on complex surfaces and the accuracy of three-dimensional morphology reconstruction, demonstrating good adaptability and stability in multi-scenario industrial inspection.

[0041] like Figure 5As shown, the rotating adjustment component 9 includes a first rotating end plate 91 mounted on one side of the first triangular prism 6 or the second triangular prism 8 and a second rotating end plate 92 mounted on the other side. Both the first rotating end plate 91 and the second rotating end plate 92 have a first receiving groove 93 inside, which is used to receive the end of the first triangular prism 6 or the second triangular prism 8. The first side plate 12 is connected to the first rotating end plate 91, and the second side plate 13 is connected to the second rotating end plate 92. Furthermore, both the first side plate 12 and the second side plate 13 have a first U-shaped groove 52 and a second U-shaped groove 53. 3. The first U-shaped groove 52 and the second U-shaped groove 53 are arc-shaped and symmetrically arranged. The end of the first rotating end plate 91 is inserted into the first side plate 12. Similarly, the end of the second rotating end plate 92 is inserted into the second side plate 13, thereby achieving stable installation and adjustment. The first rotating end plate 91 is rotated and adjusted inside the first U-shaped groove 52 and the second U-shaped groove 53 of the first side plate 12. The second rotating end plate 92 is rotated and adjusted synchronously inside the first U-shaped groove 52 and the second U-shaped groove 53 of the second side plate 13, thereby adjusting the tilt angle of the first triangular prism 6 or the second triangular prism 8.

[0042] During the adjustment process, the first rotating end plate 91 and the second rotating end plate 92 are moved in an arc shape within the U-shaped groove by manual rotation or the use of a precision knob tool to achieve fine adjustment of the prism angle and ensure accurate control of the beam deflection. After the adjustment is completed, the position of the rotating end plate is fixed by locking screws to prevent angle deviation caused by vibration and to ensure the stability and repeatability of the optical system during the detection process.

[0043] like Figure 1 As shown, the mounting housing 1 includes an upper plate 101, a left side plate 102, a right side plate 103, an inner side plate 104, and an outer side plate 105. The upper plate 101, the left side plate 102, the right side plate 103, the inner side plate 104, and the outer side plate 105 together enclose an inverted cuboid, which has a receiving cavity 2 inside for accommodating optical elements forming the first optical path 3 and the second optical path 4, as well as the optical path transmission space.

[0044] like Figure 2 and Figure 3As shown, the lower part of the upper plate 101 is provided with an arc-shaped concave surface 11; a first light-emitting plate 31, a second light-emitting plate 41, a third light-emitting plate 42, and a fourth light-emitting plate 43 are mounted on the arc-shaped concave surface 11; the first light-emitting plate 31, the second light-emitting plate 41, the third light-emitting plate 42, and the fourth light-emitting plate 43 are distributed along the arc-shaped concave surface 11. The back of the light-emitting plate can be coated with thermally conductive adhesive, which not only bonds and fixes the light-emitting plate, but also effectively conducts the heat generated during operation to the upper plate 101. The upper plate 101 is provided with heat dissipation fins 112, which are arranged in parallel longitudinal directions. Several cooling fans 113 are mounted on the upper part of the heat dissipation fins 112; the cooling fans 113 accelerate heat dissipation through forced convection, effectively reduce the operating temperature of the light-emitting plate, and prevent light intensity attenuation or wavelength drift caused by heat accumulation.

[0045] like Figure 1 As shown, the heat dissipation fins 112 and the upper plate 101 are integrally formed, ensuring a continuous and efficient heat conduction path while reducing the impact of assembly errors on heat dissipation performance.

[0046] like Figure 4 As shown, the inner side plate 104 and the outer side plate 105 are each provided with four second receiving grooves 106. The second receiving grooves 106 are used to receive the two ends of the first focusing rod 32, the second focusing rod 44, the third focusing rod 45 and the fourth focusing rod 46. In order to ensure the coaxiality and stability of the focusing rod installation, the lower part of the inner side plate 104 and the outer side plate 105 are each provided with a support plate 107. The support plate 107 is provided with four third receiving grooves 108. The third receiving grooves 108 are used to receive the lower parts of the two ends of the first focusing rod 32, the second focusing rod 44, the third focusing rod 45 and the fourth focusing rod 46. The support plate 107 is used to support and lift the lower part of the focusing rod, and can also finely adjust the vertical height of the focusing rod. By adjusting the thickness of the shims between the support plate 107 and the inner side plate 104 and the outer side plate 105, the vertical height of the focusing rod can be adjusted to ensure that the optical coupling efficiency between each focusing rod and the corresponding light-emitting plate reaches the optimal level.

[0047] Of course, a shim can also be placed on the third receiving groove 108 to fine-tune the contact surface between the focusing rod and the groove, thereby further improving the installation accuracy.

[0048] To prevent interference between light rays, a first partition 321 is installed between the first focusing rod 32 and the second focusing rod 44, a second partition 322 is installed between the second focusing rod 44 and the third focusing rod 45, and a third partition 323 is installed between the third focusing rod 45 and the fourth focusing rod 46. The partitions have a T-shaped cross-section structure, with their vertical portions embedded in the gaps between adjacent focusing rods and their horizontal portions extending below the focusing rods to form a light-shielding awning, effectively blocking the lateral diffusion and cross-interference of stray light. The surface of the partitions is treated with a matte black finish to maximize the absorption of stray light and improve the signal-to-noise ratio of the optical system.

[0049] To position and install the diffuser plate 47, a fifth receiving groove 324 is provided at the lower part of the first partition 321. The diffuser plate 47 is accommodated inside the fifth receiving groove 324. One side of the diffuser plate 47 is fixedly connected to the first partition 321 by connecting bolts, and the other side is also fixedly connected to the second partition 322 by connecting bolts. In this embodiment, the diffuser plate 47 is only installed below the second focusing rod 44. In other embodiments, the diffuser plate can be installed below any focusing rod according to optical requirements, and its position and number can be flexibly configured to achieve uniform light field in a specific area. Furthermore, the diffuser plate 47 can also be replaced to adapt to different color temperature or light intensity requirements. The diffuser plate 47 can be removed by removing the connecting bolts and replaced with a substitute with different diffusion angles or transmittance, thereby adapting to various lighting scenarios.

[0050] like Figure 6 and Figure 9 As shown, the longitudinal adjustment component 49 is used to install the filter 48 and move the filter 48 longitudinally. The longitudinal adjustment component 49 and the filter 48 are both installed at the lower part of the diffuser plate 47. The second light-emitting plate 41 emits light, which passes through the second focusing rod 44 and the diffuser plate 47 in sequence, and can be selectively filtered by the filter 48, reaching the inclined surface of the second triangular prism 8 and being refracted, and irradiating the surface of the object 7 being measured.

[0051] Specifically, such as Figure 6 and Figure 9 As shown, the longitudinal adjustment component 49 includes a receiving plate 491 installed at the lower part of the diffuser plate 47. The receiving plate 491 is provided with a fourth receiving groove 492 for receiving the filter 48. An annular cover plate 493 is provided at the lower part of the receiving plate 491 to restrict the vertical movement of the filter 48. The width of the fourth receiving groove 492 is longer than the width of the filter 48, so the filter 48 can slide longitudinally in the fourth receiving groove 492 to realize the entry and exit of the filter 48 into the optical path.

[0052] like Figure 6 and Figure 9As shown, the longitudinal adjustment assembly 49 further includes a first cover plate 494 respectively installed on the lower part of the inner side plate 104 and the outer side plate 105. The two first cover plates 494 are fixedly connected to the inner side plate 104 and the outer side plate 105 by bolts. The first cover plate 494 is provided with a longitudinal third U-shaped groove 495. A hand-tightening bolt 496 is installed inside the third U-shaped groove 495. The hand-tightening bolt 496 passes through the longitudinal third U-shaped groove 495 and is threadedly connected to the receiving plate 491. By adjusting the position of the hand-tightening bolt 496 in the third U-shaped groove 495, the longitudinal movement of the receiving plate 491 and the filter 48 can be realized.

[0053] Loosening the hand-tightening bolt 496 allows the receiving plate 491 to move longitudinally, thereby moving the filter 48 into or out of the optical path and enabling real-time control of the emitted light. When the filter 48 is fully engaged in the optical path, the light is modulated by the filter 48, changing its wavelength composition to meet specific detection requirements. When the original spectrum output is needed, the light exits the optical path through the filter 48, avoiding the introduction of additional optical attenuation. The entire adjustment process does not require disassembly of components, is convenient to operate, and has high repeatability, effectively improving the system's adaptability and stability under various operating conditions.

[0054] like Figure 1 As shown, a cable outlet 114 is installed on the upper part of the inner side plate 104. Several power lines 115 are installed on the cable outlet 114. The power lines 115 are electrically connected to the first light-emitting plate 31, the second light-emitting plate 41, the third light-emitting plate 42, and the fourth light-emitting plate 43, respectively, and drive each light-emitting plate to emit light outward. The power lines 115 independently control the switching, brightness, wavelength, and color of each light-emitting plate, realizing the on-demand combination output of multiple light sources to meet the detection requirements of different materials, colors, and surface characteristics. By programming and preset multiple lighting modes, the system can quickly switch to the spectral configuration required for the corresponding working condition, improving detection efficiency and adaptability. Each power line is independently wired and does not interfere with each other, ensuring stable and reliable signal transmission.

[0055] The optical path diagram of the integrated light source is as follows: Figure 2 As shown, in the first optical path 3, the first light-emitting plate 31 emits white light at an angle downwards, and the first focusing rod 32 converges the light emitted by the first light-emitting plate 31 to the inclined surface of the first triangular prism 6. The inclined surface of the first triangular prism 6 refracts the light of the first optical path 3 onto the surface of the object 7 to be measured on the right. The first optical path 3 has only one first light-emitting plate 31, which can be used as auxiliary lighting.

[0056] The second optical path 4 includes a second light-emitting plate 41, a third light-emitting plate 42, and a fourth light-emitting plate 43 arranged side by side. A second focusing rod 44, a third focusing rod 45, and a fourth focusing rod 46 are respectively installed below the second light-emitting plate 41, the third light-emitting plate 42, and the fourth light-emitting plate 43. The second focusing rod 44, the third focusing rod 45, and the fourth focusing rod 46 respectively converge the light from the corresponding light-emitting plates to the inclined surface of the second triangular prism 8, concentrating the light beams of the three light-emitting plates and combining them into a main illumination beam. The inclined surface of the second triangular prism 8 refracts the light from the second optical path 4 onto the surface of the same object 7 being measured, so that the light beams overlap and illuminate the surface of the object 7 being measured.

[0057] The second light-emitting plate 41 emits red and blue light downwards, which passes through the second light-concentrating rod 44 and the diffuser plate 47 in sequence, and can be filtered by the filter 48, reaching the inclined surface of the second triangular prism 8 and being refracted, and then illuminating the surface of the object 7 being measured.

[0058] The third light-emitting plate 42 and the fourth light-emitting plate 43 emit white light downwards. The third light-concentrating rod 45 and the fourth light-concentrating rod 46 respectively converge the light from the corresponding light-emitting plates to the inclined surface of the second triangular prism 8. The inclined surface of the second triangular prism 8 refracts the light from the second light path 4 onto the surface of the same object 7 under test, so that the light overlaps and illuminates the surface of the object 7 under test.

[0059] During use, the "tilt angle" of the light is adjusted in real time and precisely according to the actual three-dimensional shape of the object being measured 7. The angle of the first triangular prism 6 or the second triangular prism 8 can be adjusted by rotating the adjustment component 9. For example, the second light 4 controlled by the second triangular prism 8 can be precisely adjusted to an extremely low angle to form strong grazing illumination to highlight small protrusions. At the same time, the first light 3 controlled by the first triangular prism 6 can be adjusted to a higher angle to serve as overall supplementary lighting to suppress excessively dark shadows. This achieves "one light, multiple functions" and can cope with various detection conditions without physically replacing the light source.

[0060] The assembly method of the integrated light source:

[0061] Step S1: Remove the upper plate 101, and use thermally conductive adhesive to bond the first light-emitting plate 31, the second light-emitting plate 41, the third light-emitting plate 42 and the fourth light-emitting plate 43 to the arc-shaped concave surface 11; install a cooling fan 113 on the upper part of the upper plate 101.

[0062] Step S2: An inner side plate 104 and an outer side plate 105 are installed on both sides of the upper plate 101. A cable outlet 114 is installed on the upper part of the inner side plate 104. Multiple power lines 115 pass through the cable outlet 114 and the inner side plate 104 and are electrically connected to the first light-emitting plate 31, the second light-emitting plate 41, the third light-emitting plate 42 and the fourth light-emitting plate 43 respectively.

[0063] Step S3: Place the lower parts of the first focusing rod 32, the second focusing rod 44, the third focusing rod 45 and the fourth focusing rod 46 at both ends in the third receiving groove 108 on the support plate 107; fix the support plates 107 at both ends to the inner side plate 104 and the outer side plate 105 respectively.

[0064] Step S4: A first partition 321, a second partition 322, and a third partition 323 are installed between the first focusing rod 32, the second focusing rod 44, the third focusing rod 45, and the fourth focusing rod 46; the two ends of the partitions are bolted to the inner side plate 104 and the outer side plate 105 respectively; the left side plate 102 and the right side plate 103 are also installed on the left and right sides of the upper plate 101; the upper plate 101, the left side plate 102, the right side plate 103, the inner side plate 104, and the outer side plate 105 together form an inverted cuboid with an internal cavity 2 for accommodating the optical elements forming the first optical path 3 and the second optical path 4, as well as the optical path transmission space;

[0065] Step S5: The diffuser plate 47 is placed inside the fifth receiving groove 324. One side of the diffuser plate 47 is fixedly connected to the first partition plate 321 by connecting bolts, and the other side is also fixedly connected to the second partition plate 322 by connecting bolts.

[0066] Step S6: The filter 48 is placed inside the fourth receiving groove 492 of the receiving plate 491. The annular cover plate 493 is fixedly connected to the receiving plate 491, vertically fixing the filter 48. Therefore, the filter 48 can slide longitudinally within the fourth receiving groove 492. The two first cover plates 494 are fixedly connected to the inner side plate 104 and the outer side plate 105 respectively. The receiving plate 491 is placed on the upper part of the first cover plate 494. A hand-tightening bolt 496 is installed inside the third U-shaped groove 495. The hand-tightening bolt 496 passes through the longitudinal third U-shaped groove 495 and is threadedly connected to the receiving plate 491. By adjusting the position of the hand-tightening bolt 496 within the third U-shaped groove 495, the longitudinal movement of the receiving plate 491 and the filter 48 can be achieved.

[0067] Step S7: The inner side plate 104 is fixedly connected to the upper part of the second side plate 13, and the outer side plate 105 is fixedly connected to the upper part of the first side plate 12. The end of the first triangular prism 6 or the second triangular prism 8 is inserted into the first receiving groove 93. The end of the first rotating end plate 91 is inserted into the first side plate 12. Similarly, the end of the second rotating end plate 92 is inserted into the second side plate 13. The connecting bolt passes through the first U-shaped groove 52 and the second U-shaped groove 53 and is fixedly connected to the first rotating end plate 91 and the second rotating end plate 92 respectively. The connecting bolt rotates inside the first U-shaped groove 52 and the second U-shaped groove 53 to adjust the tilt angle of the first triangular prism 6 or the second triangular prism 8.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
