Description

Technical Field

[0001] This utility model relates to the field of detection light source technology, and in particular to a strobe double-ring light source for cable appearance inspection. Background Technology

[0002] In the manufacturing process of automotive wiring harnesses, communication cables, and other products, 360-degree visual inspection is a core process for ensuring product quality. Common defects include scratches, dents, indentations, and contamination.

[0003] Existing detection light sources have the following drawbacks:

[0004] 1. The challenge of 360-degree full inspection: Ordinary light sources (such as single-point LEDs or fixed array light sources) cannot cover the circumference of the cable, resulting in 15% to 20% blind spots. To achieve full inspection, additional rotating mechanisms or multiple cameras are required, which not only increases the equipment size by 40% but also extends the single inspection time to 10 to 15 seconds.

[0005] 2. Problem of uneven imaging due to material: Wire harnesses often contain black and white materials such as insulation layer and conductor. Due to the fixed brightness of ordinary light source, there are significant differences in imaging under strong and weak reflection (the inconsistency rate is 20% to 30%), which can easily lead to false detection.

[0006] While existing solutions attempt to use multiple light source combinations, their low integration and complex control prevent them from simultaneously addressing the two major problems mentioned above. Therefore, there is an urgent need for a compact and intelligent light source system to achieve efficient full inspection and consistent imaging. Utility Model Content

[0007] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a strobe dual-ring light source for cable appearance inspection. This invention eliminates blind spots in the inspection, achieves 360-degree uniform illumination, effectively reduces inspection time, improves inspection efficiency, and at the same time, through brightness self-adaptation, effectively reduces the inconsistency rate of inspection and improves inspection quality.

[0008] To achieve the above objectives, this utility model provides a strobe dual-ring light source for cable appearance inspection, comprising:

[0009] A connector, on which a connection station is provided;

[0010] The main controller integrates a strobe module;

[0011] Two ring light source components are respectively installed at the upper and lower ends of the connection station, so that the two ring light source components are coaxially arranged and form a double ring structure distributed vertically. Each ring light source component is electrically connected to the main controller and is controlled by the strobe module to flash light alternately in a time-division manner. Each ring light source component is provided with a light-emitting surface, and the light-emitting surfaces of the two ring light source components are arranged opposite each other.

[0012] Furthermore, each annular light source has a first slot on one side for inserting a cable.

[0013] Furthermore, the connecting seat includes a first connecting part and a second connecting part and a third connecting part that are perpendicular to the upper and lower ends of the first connecting part. The inner walls of the first connecting part, the second connecting part and the third connecting part form a connecting station with an opening on one side.

[0014] Furthermore, the second and third connecting portions are provided with arc-shaped recesses that cooperate with the two ring light source assemblies.

[0015] Furthermore, the ring light source assembly includes a perimeter, a base, a diffuser plate, and an LED circuit board. Each of the perimeter, base, diffuser plate, and LED circuit board has an opening on one side. After assembly, the perimeter, base, diffuser plate, and LED circuit board form the aforementioned first slot. The base and diffuser plate are respectively fixed to the upper and lower ends of the perimeter. The diffuser plate, perimeter, and base enclose each other to form an internal light cavity. The LED circuit board is snapped into the perimeter and placed inside the internal light cavity.

[0016] Furthermore, the LED circuit board has a horn-shaped structure, with a first stepped portion formed on the base, and a first snap-fit ​​ring provided on the inner wall of the perimeter. The two ends of the LED circuit board abut against the first stepped portion and the first snap-fit ​​ring respectively, thereby snapping it into the perimeter. The LED circuit board is arranged in an arc shape along the inner wall of the perimeter.

[0017] Furthermore, the LED circuit board has a plurality of LED units arranged on its inner side, with each LED unit arranged sequentially from the inside out around the axis of the LED circuit board.

[0018] Furthermore, the diffuser plate includes a diffuser portion with a trumpet-shaped structure, the inner side of the diffuser portion extending upward to form a first blocking portion, and the outer side of the diffuser plate extending horizontally to form a fifth connecting portion, the fifth connecting portion being fixedly connected to the lower end of the periphery.

[0019] Furthermore, the base is a hollow ring structure, with the inner side of the base extending downward to form a second shielding part. The base is fixed to the upper end of the periphery, and the first shielding part abuts against the second shielding part, forming the internal light cavity by surrounding the inner wall of the periphery.

[0020] Furthermore, it also includes a baffle, on which a first mounting part is provided, the baffle has a baffle connecting part and a baffle body arranged perpendicularly to each other, the baffle connecting part is fixed to the first mounting part, and the baffle body covers the openings provided in the perimeter, the diffuser plate and the LED circuit board.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention employs two coaxially arranged ring light source components, with a first slot on one side of each component. This significantly simplifies the installation process and cable routing of the light source on existing production lines, reduces equipment modification costs, effectively eliminates blind spots in detection, and achieves 360-degree omnidirectional uniform illumination. Simultaneously, the abutting fit between the first and second shielding parts and the surrounding sealing design effectively prevent light leakage, significantly improving illumination concentration and light utilization. The main controller connects to a strobe drive module to achieve precise driving of the dual-ring light sources. Attached Figure Description

[0034] The technology of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0037] like Figures 1 to 8 The present invention discloses a strobe dual-ring light source for cable appearance inspection, including a connector 1, a main controller and two ring light source assemblies 2;

[0038] like Figure 1 and Figure 2 As shown, the connector 1 in this embodiment includes a first connector 11 and a second connector 12 and a third connector 13 that are perpendicular to the upper and lower ends of the first connector 11. The inner walls of the first connector 11, the second connector 12 and the third connector 13 form a connector station 14 with an opening 27 on one side.

[0039] like Figure 2 As shown, the second connecting part 12 and the third connecting part 13 are provided with arc-shaped recesses 15 that cooperate with the two ring light source assemblies 2. The arc-shaped recesses 15 are consistent with the inner ring arc of the ring light source assembly 2, which can achieve precise positioning during the installation of the ring light source assembly 2 and facilitate installation.

[0040] In this embodiment, the main controller is an external controller, which integrates a strobe module to control the operation of the ring light source assembly 2.

[0041] like Figure 1 As shown, in this embodiment, the two ring light source components 2 are respectively installed at the upper and lower ends of the connection station. That is, the upper ring light source component 2 is fixed to the inner wall of the second connection part 12, and the lower ring light source component 2 is fixed to the inner wall of the third connection part 13, so that the two ring light source components 2 are coaxially arranged and form a double ring structure distributed vertically. Each ring light source component 2 is electrically connected to the main controller and is controlled by the strobe module to flash light alternately in a time-division manner. Each ring light source component 2 is provided with a light-emitting surface 21. The light-emitting surfaces 21 of the two ring light source components 2 are arranged opposite each other and both face the central axis of the connection station to provide all-round illumination of the surface of the cable 3 passing through the central axis. When the cable 3 moves along the axial direction during the detection process, the main controller controls the upper and lower ring light source components 2 to light up alternately through the strobe module, so that the circumferential surface of the cable 3 is illuminated by the instantaneous light source at different angles in sequence. With the help of the high-speed camera device, a clear 360-degree appearance image is captured, realizing efficient and blind-spot-free online detection.

[0042] To facilitate the insertion of the cable 3, in this embodiment, a first slot 22 for inserting the cable 3 is provided on one side of each annular light source.

[0043] like Figures 2 to 4 As shown, each ring light source assembly 2 includes a perimeter 23, a base 24, a diffuser plate 25, and an LED circuit board 26. The perimeter 23, base 24, diffuser plate 25, and LED circuit board 26 are all hollow ring structures with an opening 27 on one side. After assembly, the perimeter 23, base 24, diffuser plate 25, and LED circuit board 26 form the aforementioned first slot 22. The base 24 and diffuser plate 25 are respectively fixed to the upper and lower ends of the perimeter 23. The diffuser plate 25, perimeter 23, and base 24 enclose each other to form an internal light cavity 28. The LED circuit board 26 is snapped into the perimeter 23 and placed inside the internal light cavity 28.

[0044] like Figures 4 to 7As shown, the LED circuit board 26 in this embodiment has a horn-shaped structure. A first step 241 is formed on the base 24, and a first snap-fit ​​ring 231 is provided on the inner wall of the perimeter 23. The two ends of the LED circuit board 26 abut against the first step 241 and the first snap-fit ​​ring 231 respectively, so as to snap into the perimeter 23. The LED circuit board 26 is arranged in an arc shape along the inner wall of the perimeter 23. A plurality of LED units 261 are provided on the inner side of the LED circuit board 26. Preferably, the LED unit 261 is a ring-shaped array composed of multiple LED beads. Each LED unit 261 is arranged sequentially from the inside to the outside around the axis of the LED circuit board 26, forming a ring arrangement at different positions as shown in the figure, so as to realize light illumination at different angles and meet the needs of multi-angle imaging of the surface of the cable 3.

[0045] like Figure 8 As shown, the diffuser plate 25 in this embodiment includes a diffuser portion 251 with a trumpet-shaped structure. The inner side of the diffuser portion 251 extends upward to form a first shielding portion 252, and the outer side of the diffuser plate 25 extends horizontally to form a fifth connecting portion 253. The fifth connecting portion 253 is fixedly connected to the lower end of the periphery 23, that is, mounting holes that cooperate with each other are provided at the lower end of the fifth connecting portion 253 and the periphery 23, and are fixed relative to each other by screws.

[0046] like Figure 4 and Figure 7 As shown, the base 24 in this embodiment is a hollow ring structure. The inner side of the base 24 extends downward to form a second shielding part 242. The base 24 is fixed to the upper end of the perimeter 23. The first shielding part 252 abuts against the second shielding part 242 and surrounds the inner wall of the perimeter 23 to form an internal light cavity 28.

[0047] like Figure 1 As shown, this embodiment also includes a baffle 29. A first mounting part 243 is provided on the base 24. The baffle 29 is provided with a baffle 29 connecting part and a baffle 29 body arranged perpendicularly to each other. The baffle 29 connecting part is fixed to the first mounting part 243. The baffle 29 body covers the perimeter 23, the diffuser plate 25 and the opening 27 provided on the LED circuit board 26.

[0048] In some implementations, an image sensor may also be provided to provide real-time feedback of material signals to the cable 3 under test, triggering automatic brightness switching, thereby further improving detection accuracy and automation.

[0049] This invention utilizes two opposing and coaxial ring-shaped light source components 2 to ensure that the cable 3 is symmetrically illuminated from top to bottom after passing through the first slot 22 and entering the optical cavity, eliminating shadow blind spots. The ring-shaped LED units 261 of the two sets of LED circuit boards 26 are arranged in a complementary layout, which, combined with the wide-angle diffusion characteristics of the diffuser plate 25, achieves 360° uniform illumination of the cable 3 surface, significantly improving the contrast and clarity of image acquisition and meeting the requirements of high-precision visual inspection. Simultaneously, the independent dimming of the upper and lower sets of LED circuit boards 26 by the control module allows for dynamic adjustment of the light intensity and distribution according to the diameter and surface material of the cable 3, avoiding overexposure or insufficient illumination. The overlapping structure of the first shielding part 252 and the second shielding part 242 effectively prevents interference from external ambient light, ensuring the stability of illumination within the internal optical cavity 28.

[0050] 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.
