Description

Technical Field

[0001] This utility model belongs to the field of light source detection technology, specifically relating to a multi-angle line light source detection device. Background Technology

[0002] In modern industrial production, whether it is the casing of electronic products, automotive parts, or machined parts, surface scratches, blemishes, and other defects can affect the appearance quality and performance of the products. The light source detection devices used for defect detection usually use a single-direction light source. Simply put, the light source only illuminates the surface of the object being inspected from a fixed angle. This single-angle light source illumination method may not be able to fully illuminate all areas of the surface of some parts with curved surfaces or grooves, resulting in defects in some areas not being effectively detected.

[0003] Furthermore, existing light source detection equipment uses a continuously lit light source. While this method can ensure the stability of the light source, in practical applications, for some defects that need to be compared and detected under different light intensities, such as the reflection of tiny scratches under different light intensities, a continuously lit light source cannot provide such dynamic changes in light intensity. In other words, a continuously lit light source cannot flexibly adjust the illumination mode according to the detection requirements, thus affecting the accuracy of the detection.

[0012] Preferably, each of the main light strips has a power interface connected to its bottom rear side.

[0013] Preferably, the upper control board and the lower control board integrate a multi-channel time-sharing control module.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the combination of the upper light strip, the main light strip and the lower light strip, as well as the inclined design of the upper mounting plate and the lower mounting plate, enables light to be projected onto the surface of the object to be inspected from multiple directions and angles, covering a wider detection range and ensuring that light can illuminate the potential scratch areas on the surface of the object from multiple directions.

This invention can flexibly adjust the lighting sequence and time interval of the light strips through a multi-channel time-sharing control module according to different detection needs and the characteristics of the object surface, so as to ensure that the light can be more evenly irradiated to various areas of the object surface. Since scratches or defects will present different reflection or shadow effects under light from different angles, the light source in this invention can capture these subtle changes to more accurately identify and locate potential defects, thereby improving the accuracy of defect detection. In this invention, a heat dissipation component is provided on the rear side of the reinforcing plate, and multiple heat dissipation windows are opened on the rear side of the outer casing.

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. Example

[0018] like Figures 1 to 5The multi-angle linear light source detection device shown includes a housing 1, an upper mounting plate 2 on the front top of the housing 1, and a lower mounting plate 3 on the front bottom of the housing 1. A left cover plate 4 and a right cover plate 5 are installed between the upper mounting plate 2, the lower mounting plate 3, and the front of the housing 1. An upper control plate 6 and a lower control plate 7 are connected between the left cover plate 4 and the right cover plate 5. Both the upper control plate 6 and the lower control plate 7 are annular. A plurality of first oblique angle mounting blocks 8 are evenly distributed on the top of the upper control plate 6, and a plurality of second oblique angle mounting blocks 9 are installed on the bottom of the lower control plate 7. An upper light strip 10 is installed between the first oblique angle mounting blocks 8 and the upper mounting plate 2, and a lower light strip 11 is installed between the second oblique angle mounting blocks 9 and the lower mounting plate 3. An upper control plate 6 and a lower control plate 7 are connected to each other. There is a main light strip 12; the number of the first and second oblique mounting blocks 8 is the same; a reinforcing plate 13 is symmetrically connected between the rear sides of the upper control plate 6 and the lower control plate 7, and heat sinks 14 are symmetrically provided on the reinforcing plate 13; multiple heat dissipation windows 15 are opened on the rear side of the housing 1, and the heat dissipation windows 15 are located on the horizontal outer side of the heat sinks 14; the tilt angle of the upper mounting plate 2 and the lower mounting plate 3 is 30-60°, and the annular angle of the upper control plate 6 and the lower control plate 7 is ≤180°; a charging plate 16 is installed on the rear side of the left cover plate 4, and a charging port 17 is provided on the left side of the charging plate 16, which protrudes from the housing 1; a power interface 18 is connected to the rear bottom of the main light strip 12; a multi-channel time-sharing control module is integrated on the upper control plate 6 and the lower control plate 7.

[0019] This invention, through the cooperation of the upper light strip 10, the main light strip 12, and the lower light strip 11, and the inclined design of the upper mounting plate 2 and the lower mounting plate 3, allows light to be projected onto the surface of the object to be inspected from multiple directions and angles, covering a wider detection range and ensuring that the light can illuminate potential scratch areas on the object surface from multiple directions. In this invention, the multi-channel time-sharing control module integrated on the upper control plate 6 and the lower control plate 7 can sequentially send control signals to each light strip according to a preset program and time sequence, realizing the alternating illumination of the light strips and ensuring that the device can illuminate the object surface from multiple different angles and directions during the inspection process. This invention can be adapted to different inspection needs and the characteristics of the object surface through multi-channel time-sharing... The control module flexibly adjusts the lighting sequence and time interval of the light strips to ensure that the light can be more evenly irradiated to various areas of the object surface. Since scratches or defects will present different reflection or shadow effects under light from different angles, the light source in this invention can capture these subtle changes to more accurately identify and locate potential defects, thereby improving the accuracy of defect detection. In this invention, a heat sink 14 is provided on the rear side of the reinforcing plate 13, and multiple heat dissipation windows 15 are opened on the rear side of the outer casing 1. The heat dissipation windows 15 correspond to the positions of the heat sink 14, which can ensure that the heat generated by the device during operation can be discharged from the outer casing 1 in a timely manner, achieving effective heat dissipation, avoiding the impact of overheating on the performance and service life of the device, and ensuring the stable operation of the device. Example

[0020] like Figures 1 to 5 The multi-angle line light source detection device shown includes a housing 1, which can be made of aluminum alloy, which has good mechanical strength, heat dissipation performance and corrosion resistance, and can ensure that the device maintains stable structural performance in various complex working environments. The top front side of the housing 1 is provided with an upper mounting plate 2, and the bottom front side of the housing 1 is provided with a lower mounting plate 3. Some light strips are installed on the upper mounting plate 2 and the lower mounting plate 3. In order to realize multi-angle detection, both the upper mounting plate 2 and the lower mounting plate 3 are designed to be tilted inward, with a tilt angle of 30-60°. This tilt design allows the light emitted by the light strip to illuminate the surface of the object to be detected at a specific angle, thereby covering a wider detection range.

[0021] A left cover plate 4 and a right cover plate 5 are installed between the upper mounting plate 2, the lower mounting plate 3, and the front side of the outer casing 1. Specifically, the left cover plate 4 connects the left side of the upper mounting plate 2 and the lower mounting plate 3 to the front side of the outer casing 1, and the right cover plate 5 connects the right side of the upper mounting plate 2 and the lower mounting plate 3 to the front side of the outer casing 1. An upper control plate 6 and a lower control plate 7 are connected between the left cover plate 4 and the right cover plate 5. The upper control plate 6 and the lower control plate 7 are symmetrically arranged, and both the upper control plate 6 and the lower control plate 7 are ring-shaped with an annular angle of approximately 180°. This angle design allows the light strips on the control plate to be arranged around the center of the object to be detected, thereby enabling detection of the object surface from multiple directions, covering most of the object surface area, and ensuring comprehensive detection.

[0022] Multiple first angled mounting blocks 8 are evenly distributed on the top of the upper control plate 6. This allows the upper light strip 10 installed between the first angled mounting blocks 8 and the upper mounting plate 2 to exhibit an inclined divergence angle. The angle between the upper light strip 10 and the upper mounting plate 2 is such that the closer it is to the upper mounting plate 2, the larger the angle; that is, the light source of the upper light strip 10 will converge towards the upper mounting plate 2. Correspondingly, the bottom of the lower control plate 7 has the same number of second angled mounting blocks as the first angled mounting blocks 8. The lower light strip 11 installed between the second angled mounting blocks and the lower mounting plate 3 also exhibits an inclined divergence angle. The angle between the lower light strip 11 and the lower mounting plate 3 is such that the closer it is to the lower mounting plate 3, the larger the angle; that is, the light source of the lower light strip 11 will converge towards the lower mounting plate 3. Meanwhile, a main light strip 12 is installed between the upper control board 6 and the lower control board 7. The main light strip 12 is in a vertical position, but the installation layout is mainly designed according to the annular angle of the control board. As a result, the light source of the main light strip 12 will also be concentrated at the center of the upper control board 6 and the lower control board 7. With the cooperation of the three, the linear light source emitted by the light strip can project light onto the surface of the object to be inspected from different directions and angles, covering a wider detection range and ensuring that the light can illuminate the potential scratch area on the surface of the object from multiple directions.

[0023] Furthermore, a charging plate 16 is installed on the rear side of the left cover plate 4. A charging port 17 is provided on the left side of the charging plate 16. The charging port 17 protrudes from the outer shell 1, allowing the operator to power the control board and the light strip through the charging port 17. The bottom rear side of the main light strip 12 is connected to a power interface 18. It is known that the upper and lower light strips 11 are electrically connected to the control board, and the upper control board 6 and the lower control board 7 are equipped with a multi-channel time-sharing control module, which can ultimately realize the alternating lighting of the light strips.

[0024] Specifically, the multi-channel time-sharing control module sends control signals to each light strip in sequence through a preset program and time sequence. At a certain moment, only a specific light strip will be lit, while other light strips are in standby mode. This method of alternating lighting can not only effectively save energy, but also ensure that the device can illuminate the surface of the object from multiple different angles and directions during the detection process.

[0025] In practical applications, the device can illuminate the object surface from different angles by sequentially lighting the upper light strip 10, the main light strip 12, and the lower light strip 11. Since scratches or defects will exhibit different reflection or shadow effects under light illumination from different angles, the device can capture these subtle changes to more accurately identify and locate potential defects. Furthermore, this embodiment can flexibly adjust the lighting sequence and time interval of the light strips through a multi-channel time-sharing control module according to different detection needs and the characteristics of the object surface. When detecting a smoother object surface, the lighting time of the main light strip 12 can be appropriately increased to obtain a clearer detection image. Conversely, when detecting a rougher object surface, the lighting time of the main light strip 12 can be shortened, while the lighting times of the upper light strip 10 and the lower light strip 11 can be increased to ensure that the light can more evenly illuminate all areas of the object surface. Example

[0026] like Figures 1 to 5 The multi-angle line light source detection device shown has a reinforcing plate 13 symmetrically connected between the upper control plate 6 and the lower control plate 7 on the left and right sides to enhance the installation stability between the upper and lower control plates 7 and the device. Two heat sinks 14 are provided on the rear side of the reinforcing plate 13. The heat sinks 14 are fans, which dissipate heat from the detection environment through fan operation. At the same time, multiple heat dissipation windows 15 are opened on the rear side of the outer shell 1. The heat dissipation windows 15 correspond to the positions of the heat sinks 14, ensuring that the device can dissipate heat from the outer shell 1 during operation and achieve effective heat dissipation.
