Description

Technical Field

[0001] This utility model relates to the field of lighting source technology, specifically to a split light source with an additional light source. Background Technology

[0002] In the field of machine vision inspection, high-precision, multi-angle illumination sources are crucial for identifying surface defects in complex structural components (such as curved metal parts and precision electronic components). Traditional light source solutions have the following limitations: although ring light sources can provide uniform circumferential illumination, they are difficult to meet the lighting needs of the object's sidewalls and deep recesses, resulting in uneven reflections or loss of details on curved surfaces;

[0003] Existing split-type light sources mostly use a combination of independently installed ring light sources and strip light sources, which have problems such as loose structure and difficulty in optical path calibration. Moreover, multiple components need to be operated separately during adjustment, resulting in low efficiency. The spacing between light sources is fixed or the adjustment range is limited, making it difficult to adapt to the detection needs of workpieces of different sizes. When replacing products, the light source system needs to be disassembled and reassembled.

[0004] Therefore, there is an urgent need for a new type of split light source with an additional light source to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] See Figures 1 to 8 This utility model discloses a split light source with an additional light source, comprising: an adjustment mechanism 300 and two sub-light sources (not labeled in the figure); the two sub-light sources are arranged side by side and opposite to each other, and the two sub-light sources emit light in the same direction; the two sub-light sources are connected by the adjustment mechanism 300 so that the relative position of the two sub-light sources is adjustable; wherein,

[0064] Each of the sub-light sources includes a U-shaped light source 100 and an additional light source (e.g., a ring light source assembly 200) disposed within the U-shaped space of the U-shaped light source 100, wherein the U-shaped space is formed between the two arms of the U-shaped light source 100 and the U-shaped space has a U-shaped opening 3;

[0065] The U-shaped openings 3 of the two U-shaped light sources 100 are arranged opposite each other so that the two U-shaped light sources 100 are arranged in a mirror symmetrical manner;

[0066] The sub-light source and the auxiliary light source are electrically connected to an external light source controller (not shown in the figure) via electrical connection lines (not labeled in the figure) to supply power to the sub-light source.

[0067] Preferably, the additional light source includes a ring light source assembly 200.

[0068] The adjustment mechanism 300 allows for adjustment of the relative positions of the two sub-light sources, enabling users to flexibly adjust the spacing or angle of the light sources according to actual applications. This improves the adaptability and versatility of the light sources and avoids the hassle of reinstalling or replacing them. The two sub-light sources are arranged in a mirror-symmetrical manner, ensuring uniform light output distribution across the target area and reducing shadows or unevenness, making them particularly suitable for scenarios requiring high-precision lighting. Each sub-light source integrates a U-shaped light source 100 and a ring-shaped light source assembly 200 into a single unit, simplifying assembly and maintenance. The modular design allows the sub-light sources to operate independently or be used in combination, enhancing system flexibility.

[0069] Preferably, the U-shaped light source 100 includes a U-shaped base 1, an LED light source array (not labeled) disposed within the base 1, and a U-shaped diffuser 2 covering the LED light source array; the diffuser 2 forms a U-shaped light-emitting surface (not labeled) on the side away from the LED light source array.

[0070] The center of the luminescent surface has an inwardly curved depression (not labeled in the figure), and the side edges of the luminescent surface form an arc-shaped depression inward along the vertical direction of the luminescent surface (not labeled in the figure).

[0071] The front surface of the light source unit is the emitting surface, with its central area recessed inward to form a smooth arc-shaped surface. The side edges also adopt an arc transition, effectively reducing the edge dark areas when light is scattered. Two U-shaped through slots are symmetrically opened on the emitting surface. The through slots extend in the vertical direction and the openings are parallel to the side edges, further enhancing the light diffusion range and achieving uniform illumination at a large angle.

[0072] The diffuser 2 converts the direct light from the LED light source array into a uniform surface light source, forming a U-shaped emitting surface through its outer surface to achieve a wide-angle and soft lighting output; it ensures that the light is projected along the emitting surface, enhancing the lighting coverage of recessed areas or objects with complex contours.

[0073] Preferably, the ring light source assembly 200 includes an adjustment assembly 5 and a ring light source 4; wherein,

[0074] The light emission direction of the ring light source 4 is the same as that of the U-shaped light source 100;

[0075] The ring light source 4 is fixedly connected to the adjustment component 5;

[0076] The adjustment component 5 is detachably mounted on the base 1 of the U-shaped light source 100 to adjust the position of the annular light source 4 relative to the U-shaped opening 3.

[0077] The adjustment component 5 can change its relationship with the U-shaped light source 100 by adjusting the relative position of the ring light source 4 within the space of the U-shaped opening 3. The light emission direction of the ring light source 4 is the same as that of the U-shaped light source 100, and they can be combined to form a composite light field to adapt to the lighting needs of different object contours (such as the detection of holes or protrusions) and improve the lighting adaptability for special workpieces.

[0078] Specifically, the adjustment component 5 includes:

[0079] A horizontal position adjustment structure (not labeled) parallel to the U-shaped surface of the U-shaped light source 100 and a vertical position adjustment structure (not labeled) perpendicular to the U-shaped surface of the U-shaped light source 100; the ring light source 4 achieves horizontal sliding through the horizontal position adjustment structure; the ring light source 4 achieves vertical sliding through the vertical position adjustment structure.

[0080] The horizontal position adjustment structure slides horizontally to adjust the lateral position of the ring light source 4 within the plane of the U-shaped opening 3, optimizing the coverage of the central light field; the vertical position adjustment structure slides vertically to adjust the height of the ring light source 4 relative to the U-shaped opening 3 (e.g., raising / lowering), controlling the incident angle of the light, avoiding obstruction or shadow interference, and expanding the flexibility of the application.

[0081] Preferably, the horizontal position adjustment structure includes:

[0082] Adjustable cantilever assembly 51, the adjustable cantilever assembly 51 includes a pair of cantilever 511 and a cantilever connecting plate 512, the pair of cantilever 511 are spaced apart and arranged parallel to the bottom surface of the base 1, and a horizontal sliding groove 513 is provided between the pair of cantilever 511.

[0083] The ring light source 4 is connected to the horizontal slide groove 513 via a slider 514 to achieve horizontal sliding of the ring light source 4;

[0084] The vertical position adjustment structure includes: a reference plate assembly 52, including a first reference plate 521 and a second reference plate 522. The first reference plate 521 is disposed opposite to and perpendicular to the bottom surface of the base 1 in the extension direction of the U-shaped arm of the U-shaped light source 100; the first reference plate 521 and the second reference plate 522 are provided with a first sliding groove 5211 and a second sliding groove 5221 along the direction perpendicular to the bottom surface of the base 1.

[0085] The first end of the cantilever 511 is provided with a first threaded hole 5111, and the second end of the cantilever 511 is connected through the cantilever connecting plate 512, which is provided with a second threaded hole 5121.

[0086] The first threaded hole 5111 matches the first slide groove 5211, and the second threaded hole 5121 matches the second slide groove 5221. A first screw 5112 is provided in the first threaded hole 5111, and a second screw 5122 is provided in the second threaded hole 5121. The vertical sliding and locking of the adjusting cantilever assembly 51 is achieved by the sliding of the screws in the slide groove.

[0087] The horizontal position adjustment structure consists of a pair of parallel cantilever arms 511 and a cantilever connecting plate 512. The cantilever arms 511 are spaced apart to form a horizontal slide groove 513. The ring light source 4 is embedded in the horizontal slide groove 513 through a slider 514 to achieve horizontal sliding along the extension direction of the cantilever arms 511.

[0088] The vertical position adjustment structure consists of a first threaded hole 5111 at the first end of the cantilever 511, which engages with a groove in the first reference plate 521 via a first screw 5112. The second end of the cantilever 511 is connected to a groove in the second reference plate 522 via a second threaded hole 5121 in the cantilever connecting plate 512, and the second screw 5122 engages with a groove in the second reference plate 522. The first screw 5112 slides within the groove to adjust the vertical displacement of the cantilever assembly 51, and tightening the screw locks the position.

[0089] The screw serves a dual function of guiding movement and locking position (loosening the screw when sliding and tightening it after positioning), eliminating the need for additional locking components; the rigid guiding structure of the horizontal slide 513 and the slider 514 ensures that the ring light source 4 moves horizontally without wobbling, avoiding light path deviation; the vertical adjustment design of the double reference plate and double screws provides stable support and prevents the cantilever 511 assembly from tilting; at the same time, this design can reuse mechanical space and reduce the volume occupied by additional brackets.

[0090] Preferably, the slider 514 is further provided with a threaded fixing hole 5141, the axis of which is perpendicular to the extension direction of the cantilever 511, and the ring light source 4 is locked in the horizontal direction by a set screw 5142 provided in the threaded fixing hole 5141.

[0091] The set screw 5142 is screwed into the threaded fixing hole 5141 to tighten the side wall of the cantilever 511, generating friction / mechanical abutment force to forcibly fix the position of the slider 514, preventing the ring light source 4 from accidentally shifting in the horizontal slide groove 513 due to vibration or external force, and ensuring the stability of the optical path.

[0092] Preferably, the adjustment mechanism 300 includes an adjustment rod assembly 6;

[0093] The adjusting rod assembly 6 includes an adjusting block 61, the adjusting part, and an adjusting rod fixing block 63, wherein the adjusting part is an adjusting rod 62;

[0094] The adjusting rod fixing block 63 is fixed to the first side wall of the non-light-emitting surface of the first sub-light source. The adjusting block 61 is symmetrically arranged on the corresponding first side wall of the second sub-light source. The adjusting block 61 has a through sliding hole 64 inside. One end of the adjusting rod 62 is fixedly connected to the adjusting rod fixing block 63, and the other end extends slidably into the sliding hole 64. The adjusting rod 62 has a limiting protrusion at the free end of the rod body. The radial dimension of the limiting protrusion is larger than the inner diameter of the sliding hole 64, so that when the adjusting rod 62 slides along the axial direction of the sliding hole 64, the stroke is limited by the contact between the limiting protrusion and the end of the sliding hole 64.

[0095] The diameter of the limiting protrusion at the free end of the adjusting rod 62 is larger than the inner diameter of the sliding through hole 64. When the adjusting rod 62 slides to its limit position, the protrusion contacts the end face of the through hole, forming a rigid mechanical limit, effectively preventing the adjusting rod 62 from coming off or displacing excessively. In a more preferred embodiment, by replacing the adjusting rod 62 with a longer one, the adjustment range of the light source is expanded, allowing this light source to adapt to the lighting needs of large workpieces.

[0096] Specifically, the adjustment mechanism 300 further includes a locking component 7; the locking component 7 includes a locking plate 71, the fixed end of the locking plate 71 is fixedly disposed on the first side wall of the second sub-light source corresponding to the adjustment block 61, and the locking end of the locking plate 71 extends to the first side wall of the first sub-light source; the locking plate 71 follows the position change of the second sub-light source relative to the first sub-light source, and a positioning groove 72 is provided on the locking end of the locking plate 71, the extension direction of the positioning groove 72 is parallel to the axial direction of the rod body of the adjustment rod 62, and the locking end is used to lock and position with the first side wall of the first sub-light source.

[0097] Specifically, the locking assembly 7 further includes a fastening assembly 8, which includes several third threaded holes 81, fourth threaded holes 82, third screws 83, and fourth screws 84. The third threaded holes 81 are formed on the first sub-light source and multiple of them are formed within the active stroke of the positioning groove 72. The third screws 83 pass through the positioning groove 72 and are screwed into the third threaded holes 81 to fasten the locking plate 71. The fourth threaded holes 82 are provided on the adjusting block 61, and the central axis of the fourth threaded hole 82 is perpendicular to the axis of the adjusting rod 62. The fourth screws 84 are screwed into them to fasten the adjusting rod 62.

[0098] When using the device, after adjusting the two light sources to a suitable distance, the user inserts the third screw 83 through the positioning slot 72 and tightens it. The third screw 83 can be a head screw, cup screw, or other type of screw, and can be used with spring washers and flat washers to secure the locking plate 71. After the positioning plate is locked, the fourth screw 84 is screwed into the fourth threaded hole 82. The fourth screw 84 can be a stop screw to lock the adjusting rod 62. If the user needs to adjust the distance between the light sources again, the user can manually adjust the distance by tightening the third screw 83 and the fourth screw 84. With the fastening components 8 and locking components 7 configured as described above, the user can efficiently complete the adjustment, locking, and maintenance of the light sources, ensuring the long-term stable operation of the equipment.
