Description

Technical Field

[0001] This utility model relates to the field of detection light source technology, and in particular to a high-brightness arc-shaped zone detection air-cooled light source. Background Technology

[0002] Since mobile phone frames have a certain curvature, it is relatively difficult to detect defects on curved surfaces. High-brightness curved surface partition detection air-cooled light source is a special light source designed for detecting defects on mobile phone frames.

[0003] Existing high-brightness curved surface zone detection air-cooled light sources do not have a relatively mature solution that can detect minor defects in one go, such as slight dents, scratches, and dents. Different defects present different shadows in the light source detection, which may lead to problems such as incorrect detection or omission.

[0004] Therefore, a high-brightness curved surface partition detection air-cooled light source is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, there is no relatively mature solution that can detect minor defects in one go, such as slight dents, scratches, and dents. Different defects present different shadows in light source detection, which may lead to problems such as incorrect detection or omission. Therefore, a high-brightness curved surface partition detection air-cooled light source is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a high-brightness arc-shaped zone detection air-cooled light source, including a housing, a cover plate fixedly installed on one side of the housing, and a diffuse light component fixedly connected to the bottom of the housing, wherein the diffuse light component is arc-shaped.

[0007] Preferably, a frame is fixedly connected inside the housing, a PCB board is fixedly installed on the inner wall of the frame, and a number of high-power LED beads are fixedly installed on the output end of the PCB board.

[0008] Preferably, the number of PCB boards and high-power LED beads are both five sets, the positional distribution of the five sets of PCB boards is adapted to the shape of the diffused light component, and the high-power LED beads are located between the opposite surfaces of the PCB boards and the diffused light component.

[0009] Preferably, heat sinks are fixedly connected to both sides and the top of the outer surface of the frame.

[0010] Preferably, an air inlet pipe is fixedly connected to the top of the housing, and two air outlet pipes are fixedly connected to the bottom of the cover plate on the side away from the housing. The air inlet pipe is located above the two sets of heat sinks at the top, and the two sets of air outlet pipes are located below the two sets of heat sinks at the bottom.

[0011] Preferably, the diffused light component is located below the high-power LED beads, and the bottom end of the diffused light component extends through the arc end of the housing.

[0012] Preferably, the diffused light assembly includes a diffused light plate one fixedly connected to the inner wall of the housing, a diffused light plate two fixedly connected inside the diffused light plate one, a diffused light plate three fixedly connected to the inner wall of the diffused light plate two, and the outer wall of the diffused light plate three fixedly connected to the inner wall of the bottom arc end of the housing. The shapes and sizes of the diffused light plate one, diffused light plate two, and diffused light plate three are uniform and adapted to the shape and size of the bottom arc end of the housing.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. This utility model provides a high-brightness arc-shaped partitioned air-cooled light source. By setting five independent PCB boards, each partition can be lit individually. While ensuring the detection area, it can perform complete and detailed detection with multi-angle light sources, thereby realizing one-time detailed detection of defects of different natures such as scratches and dents. At the same time, five images are captured by a camera and then stitched together to generate a complete image.

It can support the continuous high-power use of the light source without burning out the LEDs due to high power, thus extending the lifespan of the light source. It also avoids the problem of excessive temperature of the high-brightness curved surface partition detection air-cooled light source caused by the fast detection speed and high frequency of light source illumination.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figure 1 - Figure 3 This utility model provides a technical solution: a high-brightness arc-shaped partition detection air-cooled light source, including a housing 1, a cover plate 2 fixedly installed on one side of the housing 1, and a diffuse light component 3 fixedly connected to the bottom of the housing 1. The diffuse light component 3 is arc-shaped and has a specific curvature, which can meet the uniformity requirements of the arc edge brightness when detecting the mobile phone frame, thereby improving the illumination effect of the detection light source during the detection process and thus improving the detection accuracy.

[0023] like Figure 2 As shown, a frame is fixedly connected inside the housing 1, and a PCB board 4 is fixedly installed on the inner wall of the frame. Several high-power LED beads 5 are fixedly installed at the output end of the PCB board 4. The use of high-power LED beads 5 can greatly improve the brightness of the light source and significantly reduce the exposure time of the camera. Therefore, it can improve the detection efficiency of the product and reduce the problem that conventional partitioned image shooting will reduce the detection speed of the product.

[0024] like Figure 3 As shown, there are five sets of PCB boards 4 and five sets of high-power LED beads 5. The positions of the five sets of PCB boards 4 are adapted to the shape of the diffused light component 3, and the high-power LED beads 5 are located between the opposite surfaces of the PCB boards 4 and the diffused light component 3. By setting five independent sets of PCB boards 4, each zone can be lit up individually. By lighting up each zone in turn, the camera can capture five images, and then perform stitching processing to generate a complete image. This enables multi-angle adjustment of the detection light source, making the detection more comprehensive and capable of detecting minor defects such as minor dents, dents, scratches, etc.

[0025] like Figure 2 As shown, heat sinks 8 are fixedly connected to both sides and the top of the outer surface of the frame. The heat sinks 8 can expand the heat dissipation area of ​​the frame and the PCB board 4, thereby improving its heat dissipation efficiency. This can support the continuous use of high-power light sources without burning out the LEDs due to high power, thus extending the lifespan of the light source.

[0026] like Figure 1 and Figure 2As shown, an air inlet pipe 6 is fixedly connected to the top of the housing 1, and two air outlet pipes 7 are fixedly connected to the bottom of the cover plate 2 on the side away from the housing 1. The air inlet pipe 6 is located above the two sets of heat sinks 8 at the top, and the two sets of air outlet pipes 7 are located below the two sets of heat sinks 8 at the bottom. By connecting the air inlet pipe 6 and the air outlet pipes 7, airflow can be formed inside the housing 1. The airflow passes through the heat sinks 8 and carries away heat, thereby improving the heat dissipation effect of the high-brightness curved surface partition detection air-cooled light source. This avoids the problem of excessive temperature of the high-brightness curved surface partition detection air-cooled light source caused by the fast detection speed and the high frequency of light source illumination. This is of positive significance for the efficient and long-term stable operation of the high-brightness curved surface partition detection air-cooled light source.

[0027] like Figure 2 As shown, the diffuse component 3 is located below the high-power LED bead 5, and the bottom end of the diffuse component 3 extends through the arc end of the housing 1. The diffuse component 3 can diffuse the reflection of the mobile phone frame, thereby avoiding the problem of uneven light spots caused by the reflection of the mobile phone frame, and thus improving the reliability of detection.

[0028] like Figure 3 As shown, the diffuser assembly 3 includes a diffuser plate 31 fixedly connected to the inner wall of the housing 1, a diffuser plate 32 fixedly connected inside the diffuser plate 31, a diffuser plate 33 fixedly connected to the inner wall of the diffuser plate 32, and an outer wall of the diffuser plate 33 fixedly connected to the inner wall of the bottom arc end of the housing 1. The shapes and sizes of the diffuser plate 31, diffuser plate 32, and diffuser plate 33 are uniform and adapted to the shape and size of the bottom arc end of the housing 1. By using the diffuser plate 31, diffuser plate 32, and diffuser plate 33 that fit together, the problem of uneven light spots caused when the diffuser assembly 3 is close to the high-power LED beads 5 can be compensated, thereby improving the image quality of the camera and thus achieving the effect of improving the detection quality.

[0029] The working principle of this utility model is as follows: In use, the housing 1 is installed in a predetermined position, and the air inlet pipe 6 is connected to an air pump and other equipment. The phone frame is then passed through the arc-shaped area inside the diffuser component 3. During this process, each PCB board 4 is driven in turn, thereby illuminating the corresponding high-power LED beads 5 in turn. This allows for complete and detailed inspection with multi-angle light sources while ensuring the detection area is covered. This enables a one-time detailed inspection of defects of different natures, such as scratches and dents. Simultaneously, five images are captured by a camera and then stitched together to generate a complete image. Based on this image, minor defects on the phone frame, such as minor dents, dents, and scratches, can be detected. Furthermore, when the detection light source shines on the phone frame, some... The phone frame has a relatively high reflectivity. The reflected light hits the diffuser component 3 and is gradually diffused by the diffuser plate 31, diffuser plate 32, and diffuser plate 33, thus avoiding uneven light spots caused by reflected light. During this process, the heat sink 8 can expand the heat dissipation area of ​​the frame and PCB board 4, thereby improving its heat dissipation efficiency. It can support the continuous high-power use of the light source without burning out the LEDs due to high power, thus extending the lifespan of the light source. The airflow formed between the air inlet pipe 6 and the air outlet pipe 7 passes through the heat sink 8 and carries away heat, thereby improving the heat dissipation effect of the high-brightness curved surface partition detection air-cooled light source. This avoids the problem of excessively high temperature of the high-brightness curved surface partition detection air-cooled light source caused by the fast product detection speed and the high frequency of light source illumination.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
