Description

Technical Field

[0001] This utility model relates to the field of T-beam appearance defect imaging, and in particular includes a light source device used in T-beam appearance quality inspection. Background Technology

[0002] In intelligent inspection of T-beam appearance quality, insufficient ambient light or uneven light distribution can lead to blurry and low-contrast images, affecting subsequent image processing and defect identification. Therefore, supplementary lighting is a crucial step, playing a key role in improving the quality and accuracy of image acquisition. During T-beam appearance quality inspection, appropriate light source layout and angle selection are typically used to effectively reduce or eliminate shadows on the T-beam surface, thus avoiding interference from shadows in image analysis. Simultaneously, using a light source can significantly increase the brightness of the T-beam surface, allowing the camera to capture clearer images. Adjusting and controlling the light source can optimize image contrast, making the T-beam appearance quality defect features more prominent, facilitating subsequent image processing and identification, and ultimately improving the accuracy of T-beam appearance quality defect identification.

[0003] Traditional lighting often employs a fixed light source layout, making it difficult to flexibly adjust according to the specific shape of the T-beam and the inspection requirements. This results in uneven light distribution on the T-beam surface, with some areas receiving excessively strong or weak light, affecting the quality of image acquisition and subsequent processing. Particularly in areas with complex T-beam structures, traditional lighting often fails to provide sufficient illumination, leading to blind spots. Furthermore, traditional lighting equipment typically lacks intelligent control functions, failing to automatically adjust brightness and illumination angle according to changes in ambient light. Therefore, there is an urgent need for a light source device for inspecting the appearance quality of T-beams that can increase light intensity or improve light distribution, thereby enhancing image clarity and contrast, making defects more visible, and facilitating inspection. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a light source device for the inspection of the appearance quality of T-beams.

[0005] This light source device, used in the inspection of the appearance quality of T-beams, is installed on the two columns of the inspection gantry. The light source device includes: an LED light source, a light source controller, and a light support rod. One end of the light support rod is fixed to the column of the inspection gantry, and the other end is connected to the light source controller through an angle adjuster.

[0006] The LED light source is mounted on an angle adjuster, which controls the rotation of the light source controller, thereby controlling the pitch angle of the LED light source.

[0007] Preferably, the detection gantry moves on the track, and the lighting support rods are horizontally fixed on both sides of the detection gantry column corresponding to the length of the track, with the pitch plane of the LED light source perpendicular to the length direction of the lighting support rods.

[0008] Preferably, the LED light source is covered with a protective cover, one side of which is fixed to the outer surface of the light source controller and arranged around the LED light source, while the other side of the protective cover is open.

[0009] Preferably, a heat sink is fixed on the light source controller, and the LED light source is mounted on the heat sink.

[0010] As a preferred option, several light source devices are installed at different heights on the gantry column, and the angle adjuster and light source controller of each light source device are independent of each other.

[0011] The beneficial effects of this utility model are:

[0012] 1) This utility model adjusts the angle of the light source by means of an angle adjuster and adjusts the brightness, color temperature and wavelength of the light source by means of a light source controller to adapt to different working environments, different T-beam surface characteristics and imaging requirements; the use of high-brightness and high-uniformity LED light source can ensure that the T-beam surface receives sufficient and uniform illumination during the inspection process, thereby clearly presenting surface details and improving the accuracy of defect detection.

[0013] 2) The angle adjustment function of this utility model enables the light source to be flexibly adjusted according to different detection areas and detection needs, ensuring that the light shines on the T-beam surface at the best angle, adapting to complex and varied surface shapes, and achieving all-round, blind-angle detection without frequent replacement or adjustment of the light source position, thereby improving detection efficiency.

[0017] The present invention will be further described below with reference to embodiments. The description of the embodiments below is only for the purpose of helping to understand the present invention. It should be noted that, for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0018] As another embodiment, this light source device used in the appearance quality inspection of T-beams, such as Figure 1 and Figure 2 As shown, it is installed on the two side columns of the detection gantry 7 and moves on the track with the detection gantry 7.

[0019] The light source device includes: LED light source 1, light source controller 5 and light support rod 6. One end of the light support rod 6 is fixed on the column of the detection gantry 7. The light support rod 6 is horizontally fixed on both sides of the column of the detection gantry 7 corresponding to the length direction of the track. The pitch plane of the LED light source 1 is perpendicular to the length direction of the light support rod 6.

[0020] The other end of the light support rod 6 is connected to the light source controller 5 through the angle adjuster 4; a heat dissipation base 2 is fixed on the light source controller 5, and the LED light source 1 is installed on the heat dissipation base 2 to prevent the light heat generated by the LED light source 1 from affecting the light source controller 5.

[0021] The LED light source 1 is covered by a protective cover 3, which is also mounted on the heat dissipation base 2. The bottom of the heat dissipation base 2 is tightly connected to the bottom of the protective cover 3. One side of the protective cover 3 is fixed to the outer surface of the light source controller 5 and surrounds the LED light source 1. The other side of the protective cover 3 is open. The protective cover 3 serves to concentrate and evenly distribute the energy of the LED light source 1. At the same time, the protective cover 3 also provides a certain degree of heat insulation to prevent the light and heat generated by the LED light source 1 from being transferred to the light source device or other devices of the detection gantry 7 and causing damage.

[0022] When the angle adjuster 4 is in operation, it controls the rotation of the light source controller 5, thereby controlling the pitch angle of the LED light source 1.

[0023] In this embodiment, as Figure 2 As shown, several light source devices are installed at different heights on the column of the detection gantry 7. The angle adjuster 4 and the light source controller 5 of each light source device are independent of each other.

[0024] This device is installed on the inspection gantry column. The supplementary lighting source is a core component of the intelligent inspection system, used to provide sufficient and uniform illumination to the T-beam surface during inspection, enabling clearer capture of surface details such as cracks and bubbles. Using the angle adjuster 4, the device can be adapted to scenarios where the T-beam surface has complex shapes and different areas require different angles of illumination for clear visualization. The light source controller 5 receives instructions from the intelligent inspection system, controlling the light source's on / off state, brightness adjustment, color temperature adjustment, and wavelength adjustment, ensuring efficient, accurate, and flexible inspection.

[0025] When using this light source device, the angle adjuster 4 is adjusted according to the surface characteristics of the T-beam to be inspected, so that the surface of the LED light source 1 is parallel to the surface of the T-beam. After the T-beam appearance inspection system identifies the T-beam, it activates the light source controller 5, which automatically adjusts the brightness, color temperature, and wavelength of the light source, thereby improving the imaging clarity of the T-beam's appearance quality defect features. After the T-beam appearance inspection system has identified and completed the T-beam inspection, the light source device is turned off.
