Description

Technical Field

[0001] This utility model relates to the field of detection light sources, and in particular to a light source capable of detecting different defects. Background Technology

[0002] Material appearance defect detection is of great significance for ensuring production safety, product quality and reducing production costs. Detectable light sources refer to those that can be effectively used in specific detection systems or equipment, and whose emitted light can be accurately measured and controlled. These light sources usually have stable light emission characteristics, such as uniform brightness and stable color temperature, which are used to detect material appearance defects.

[0003] In the material production process, the methods of inspecting the appearance of materials by manual vision are relatively limited. The accuracy of the inspection is poor, and manual visual inspection inevitably suffers from problems such as visual fatigue, missed detections, and misjudgments. It is also inconvenient to use. Moreover, some existing inspection light sources are relatively simple and can only detect specific types of defects, which is not practical and has low inspection efficiency. Therefore, a light source that can detect different defects is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the limitations of existing technologies that rely on manual visual inspection of material appearance. These limitations include poor accuracy, visual fatigue, missed detections, and misjudgments, as well as inconvenience, limited applicability, and low efficiency of existing inspection light sources that can only detect specific types of defects. Therefore, this invention proposes a light source capable of detecting various defects to solve these problems.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A light source capable of detecting various defects, comprising:

[0007] The housing and the light source assembly are provided. The light source assembly is disposed in the inner cavity of the housing and is used to detect the features of the outer wall of the product. The light source assembly includes an ultraviolet lamp, a low-angle ring lamp and a shadowless lamp. The ultraviolet lamp has a first through hole in the middle, the low-angle ring lamp has a second through hole in the middle, and the shadowless lamp has a third through hole in the middle. The first through hole, the second through hole and the third through hole are coaxially arranged.

[0008] Preferably, a top plate is fixedly provided on the top of the outer casing, and a viewing window is provided on the top of the top plate.

[0009] Preferably, a lamp plate is fixedly provided on the inner wall of the ultraviolet lamp.

[0010] Preferably, a connecting wire is fixedly provided on the outer wall of the ultraviolet lamp, and the other end of the connecting wire is fixedly connected to a first light source controller.

[0011] Preferably, a second light source controller is fixedly connected to the outer wall of the shadowless lamp via another set of connecting wires.

[0012] Preferably, the outer wall of the outer shell has a connecting seam, and multiple sets of connecting seams are provided.

[0013] Preferably, the outer wall of the low-angle ring light is provided with a threaded groove, and the threaded groove is threadedly connected to the inner wall of the outer shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, by setting the connection relationship between the outer shell, ultraviolet lamp, low-angle ring lamp, and shadowless lamp, the object to be tested is placed on the outer shell, with the product to be tested coaxial with the outer shell. By turning on the shadowless lamp, the product to be tested receives multi-angle illumination, making the shadow around the product lighter and facilitating subsequent illumination and testing by other light sources. Furthermore, by turning on the ultraviolet lamp, which is positioned above the shadowless lamp, the light emitted by the upstream ultraviolet light source passes through the downstream shadowless lamp light source before illuminating the object to be tested, avoiding interference between the downstream light source and the upstream light source. The light emitted is blocked, allowing ultraviolet light to shine on the product for inspection. By turning on the low-angle ring light, the low-angle ring light shines direct light from a low angle towards the center, highlighting the edges of the object being tested and making the edges clearer, which facilitates observation of the object's condition. This improves the accuracy and reliability of the inspection. In use, users can choose any light source or a combination of multiple light sources to capture different inspection images under different lighting conditions. By comparing, synthesizing, and denoising multiple images, accurate inspection results can be obtained, improving the accuracy of defect detection for this product.

[0016] 2. In this utility model, by setting a connecting seam on the outer shell, screws are passed through the connecting seam and tightened onto the shadowless lamp, thus fixing the shadowless lamp onto the outer shell. The multiple sets of screws connected to the shadowless lamp improve the installation stability of the shadowless lamp. The connecting wire on the ultraviolet lamp passes through the connecting seam and connects to the first light source controller, so that the first light source controller is located on the outside of the outer shell, making it convenient for the user to access and adjust.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example: This example provides a light source capable of detecting different defects. See [link to example]. Figure 1-4 Specifically, including:

[0026] The system comprises a housing 1 and a light source assembly. The light source assembly is housed within the inner cavity of the housing 1 and is used to detect features on the outer wall of the product. The light source assembly includes an ultraviolet lamp 2, a low-angle ring lamp 3, and a shadowless lamp 5. The ultraviolet lamp 2 has a first through-hole in the center, the low-angle ring lamp 3 has a second through-hole in the center, and the shadowless lamp 5 has a third through-hole in the center. The first, second, and third through-holes are coaxially arranged. When detecting a product, the product to be detected is placed in the corresponding position, and the ultraviolet lamp 2, low-angle ring lamp 3, and shadowless lamp 5... The lamps 5 are coaxially arranged, forming a ring with the ultraviolet lamp 2, the low-angle ring lamp 3, and the shadowless lamp 5 to fully illuminate the object under test. This facilitates inspection of the object's surroundings and allows for easy display of its appearance. Furthermore, the distributed arrangement of the ultraviolet lamp 2, the low-angle ring lamp 3, and the shadowless lamp 5 allows users to select any one light source or a combination of multiple light sources to capture different inspection images under varying lighting conditions. By comparing, synthesizing, and denoising multiple images, accurate inspection results are obtained, ensuring the product's defect detection accuracy.

[0027] A top plate 101 is fixedly installed on the top of the outer casing 1, and a viewing window 102 is provided on the top of the top plate 101 to facilitate the user to observe the product testing status inside the outer casing 1.

[0028] The inner wall of the ultraviolet lamp 2 is fixed with a lamp plate 201. The ultraviolet lamp 2 uses a hydrogen lamp or a deuterium lamp as a light source to emit ultraviolet light. These light sources can produce ultraviolet light within a specific wavelength range. When the ultraviolet light passes through the sample, the intensity of the absorbed light will be reduced so as to make accurate measurements.

[0029] A connecting wire 401 is fixedly installed on the outer wall of the ultraviolet lamp 2, and the other end of the connecting wire 401 is fixedly connected to the first light source controller 4, which is used to control the opening and closing of the ultraviolet lamp 2, so as to facilitate self-adjustment according to the usage requirements.

[0030] The outer wall of the shadowless lamp 5 is fixedly connected to a second light source controller 6 via another set of connecting wires 401. This controller is used to control the opening and closing of the shadowless lamp 5, allowing for easy adjustment according to usage requirements. The shadowless lamp 5 achieves high-angle and low-angle illumination by changing the light path, thereby effectively weakening the texture and wrinkles on the object's surface and achieving a uniform image. By adding light sources around the illuminated object, the shadow is softened, allowing the object to be illuminated from multiple angles, resulting in a uniform overall image and facilitating the detection of the product by other light sources.

[0031] The outer wall of the outer casing 1 has a connecting seam 103. A screw is movably inserted into the inner wall of the connecting seam 103, and the shadowless lamp 5 is fixed in the inner cavity of the outer casing 1 by the screw. The connecting seam 103 is provided in multiple sets, and the multiple sets of screws are connected to the shadowless lamp 5, which further improves its stability.

[0032] The low-angle ring light 3 has a threaded groove 301 on its outer wall, and the threaded groove 301 is threaded to the inner wall of the outer shell 1. The low-angle ring light 3 includes components such as a high-density LED array, a flexible circuit board, and specific light source device processing parts. The LED bulbs are vertically soldered onto the flexible circuit board, and by adjusting the tilt angle of the circuit board, the effect of direct light illuminating the center part from a low angle can be achieved. Its low-angle illumination can highlight the edge part of the object being measured, making the edge clearer and facilitating subsequent processing and recognition. Moreover, through multi-angle low-angle illumination, the three-dimensional information of the object can be highlighted, avoiding the shadow problem caused by diagonal illumination, thereby improving the quality and accuracy of the image. The low-angle ring light has a strong ability to represent the surface unevenness of the product, and is suitable for applications such as scratch detection on wafers or glass substrates, reading engraved text, workpiece edge contour extraction, and scratch detection, thereby improving the accuracy and reliability of the detection.

[0033] Specifically, the working principle and operation method of this utility model are as follows:

[0034] In use, the product to be tested is placed on the housing 1, with the product and housing 1 coaxial. The shadowless lamp 5 is turned on by turning on the second light source controller 6. By adding light sources around the irradiated object, the shadow is reduced, allowing the product to be irradiated from multiple angles, making the overall detection image uniform and facilitating subsequent irradiation of the product by other light sources. The ultraviolet lamp 2 is turned on by turning on the first light source controller 4. The ultraviolet lamp 2 is located above the shadowless lamp 5. The light emitted by the upstream ultraviolet light source passes through the downstream shadowless lamp 5 light source and shines on the product, avoiding the downstream light source blocking the light emitted by the upstream light source. The ultraviolet light shines on the product for detection. The low-angle ring light 3 is turned on, and the low-angle ring light shines direct light from a low angle towards the center, highlighting the edge of the object and making the edge clearer. This facilitates observation of the object's condition, thereby improving the accuracy and reliability of the detection.

[0035] During use, by passing the screws through the connecting seam 103 and tightening them onto the shadowless lamp 5, the shadowless lamp 5 is fixed onto the housing 1. The multiple sets of screws connected to the shadowless lamp 5 improve the installation stability of the shadowless lamp 5. The connecting wire 401 on the ultraviolet lamp 2 passes through the connecting seam 103 and connects to the first light source controller 4, so that the first light source controller 4 is located on the outside of the housing 1, making it convenient for the user to access and adjust.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
