[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0028] The following is for reference. Figures 1-2 The present application describes a visual inspection combined light source device 100, which can be used to acquire images, enabling inspectors to judge defects on the inspected parts based on the acquired images.

[0029] According to an embodiment of this application, a visual inspection combined light source device 100 includes: a housing 1, a camera 2, a light-emitting component, and an optical glass component 4.

[0030] The light-emitting components include multiple light-emitting components, such as a first light-emitting component 31, a second light-emitting component 32, and a third light-emitting component 33. The light-emitting components can emit light to provide supplementary lighting to one side of the component being tested. The optical glass component 4 can be used to guide, diffuse, and reflect the light emitted by the light-emitting components, so that the light can be directed toward one side of the second window 102 of the housing 1 to provide supplementary lighting to the component being tested arranged on one side of the second window 102.

[0031] Reference Figure 2 As shown, the housing 1 has a cavity 103 for arranging components such as the light assembly and the optical glass assembly 4. A first window 101 and a second window 102 are formed on the housing 1. The camera 2 is arranged opposite to the first window 101 and is used to acquire images. The camera 2 can detect the concave and convex structures on the surface of the component on the side of the acquired image, so that the operator can accurately judge the defects on the component based on the image.

[0032] Reference Figure 2 As shown, the first light-emitting component 31 and the optical glass component 4 are arranged inside the cavity 103. The first light emitted by the first light-emitting component 31 is directed toward the optical glass component 4. The first light can be reflected by the optical glass component 4 toward the second window 102 side, so as to supplement the light of the detected component arranged near the second window 102 through the first light, thereby improving the image acquisition effect of the camera 2 on the detected component.

[0033] Reference Figure 2 As shown, the second light-emitting component 32 is arranged inside the cavity 103, and the second light-emitting component 32 is used to emit a second light to one side of the second window 102. The second light can be directly directed to the second window 102 to supplement the light of the detected component arranged near the second window 102, thereby improving the image acquisition effect of the camera 2 on the detected component.

[0034] Reference Figure 2As shown, the third light-emitting component 33 is arranged inside the cavity 103, and is spaced apart from the second light-emitting component 32. The third light-emitting component 33 emits a third light beam towards one side of the second window 102. The third light beam can be directly directed towards the second window 102 to provide supplementary lighting to the detected component located near the second window 102, thereby improving the image acquisition effect of the camera 2 on the detected component. The second light-emitting component 32 and the third light-emitting component 33 are arranged spaced apart within the cavity 103 to prevent interference between them.

[0035] Combination Figure 1 and Figure 2 As shown, the first window 101 and the second window 102 are respectively formed on the top wall and bottom wall of the housing 1 arranged opposite each other in the vertical direction. The camera 2 is arranged above the housing 1, and the image acquisition module in the camera 2 is arranged facing the first window 101, so that the camera 2 can acquire the image of the detected component arranged near the second window 102 through the first window 101.

[0036] It should be noted that the component being inspected can be constructed as a circuit board 200, an IC carrier board (packaging substrate), etc. Taking the circuit board 200 as an example, the surface of the circuit board 200 has depressions or protrusions of different shapes and depths. The visual inspection combined light source device 100 acquires images of the circuit board 200 to obtain clear images that can show minor defects, thereby providing reliable judgment basis for the inspectors. The component being inspected is arranged below the housing 1, and is positioned opposite the second window 102, so that the light illuminating the second window 102 can supplement the light at the component being inspected, improving the image acquisition effect of the camera 2 on the component being inspected.

[0037] In this application, the first light emitted by the first light-emitting component 31 is reflected by the optical glass component 4 towards one side of the second window 102. The second light-emitting component 32 and the third light-emitting component 33 respectively illuminate the second window 102, thereby supplementing the light to one side of the second window 102 through the first light-emitting component 31, the second light-emitting component 32, and the third light-emitting component 33. This makes the image captured by the camera 2 clearer, ensuring the clarity of the image acquisition and helping the inspector to accurately detect small defects on the inspected component based on the image captured by the camera 2. In particular, the better the image quality captured by the camera 2, the higher the accuracy of the defect judgment on the inspected component.

[0038] It should be noted that currently, in the field of visual inspection technology, a camera 2, in conjunction with a light source, can acquire surface images of components such as circuit boards 200, so that defects formed on the surface of the inspected components can be presented in an image format. However, in related technologies, the image acquisition effect of visual inspection devices on the inspected components is not ideal, failing to clearly and fully present the surface defects of the inspected components in the image, thus failing to provide reliable judgment criteria for inspectors and affecting the inspection results.

[0039] In this application, the light-emitting component and the optical glass component 4 can cooperate to supplement light to one side of the second window 102, thereby improving the image acquisition clarity of the inspected component near the second window 102 by the camera 2. By using light to fully illuminate the area where foreign objects of different regular shapes (such as: depressions and protrusions) are located on the surface of the inspected component, a clear image showing the minute defects can be obtained, providing a reliable basis for the judgment of the inspector.

[0040] like Figure 2 As shown, in some embodiments of this application, the normal direction of the first light-emitting surface 311 of the first light-emitting component 31 is horizontal, and the optical glass component 4 is arranged on the side of the first light-emitting surface 311 adjacent to the image acquisition trajectory 201 of the camera 2. The first light emitted through the first light-emitting surface 311 can be directed onto the optical glass component 4 and reflected by the optical glass component 4 towards the second window 102. It can be understood that the normal direction of the first light-emitting surface 311 is parallel, that is, the first light-emitting surface 311 is vertically arranged.

[0041] It should be noted that the optical glass assembly 4 can be constructed as a high-definition semi-transparent and semi-reflective optical glass assembly 4, thereby reflecting the first light rays towards the second window 102 through the optical glass assembly 4. (Refer to...) Figure 2 When the first light-emitting surface 311 is arranged in parallel, it facilitates the arrangement of the first light-emitting component 31 in the cavity 103. For example, the first light-emitting component 31 is placed at the bottom of the cavity 103, and the first light-emitting component 31 is installed and fixed by the inner wall of the bottom wall of the housing 1, thereby arranging the first light-emitting component 31 near the second window 102, which can improve the supplementary light effect to the second window 102.

[0042] like Figure 2 As shown, in some embodiments of this application, the angle between the normal direction of the second light-emitting surface 321 of the second light-emitting component 32 and the horizontal plane is α, and satisfies the relationship: 30°≤α≤70°.

[0043] Therefore, the second light-emitting component 32 can be tilted in the cavity 103 and illuminate the second light source towards the second window 102. The second light source can illuminate the detected component located near the second window 102 to provide supplementary lighting for the detected component, which helps to improve the clarity of the image acquired by the camera 2.

[0044] like Figure 2 As shown, in some embodiments of this application, the angle between the normal direction of the third light-emitting surface 331 of the third light-emitting component 33 and the horizontal plane is β, and satisfies the relationship: 30°≤β≤70°.

[0045] Therefore, the third light-emitting component 33 can be tilted in the cavity 103 and illuminate the third light beam towards the side of the second window 102. The third light beam can illuminate the detected component arranged near the second window 102 to achieve supplementary lighting for the detected component, which helps to improve the clarity of the image acquired by the camera 2.

[0046] In a further embodiment of this application, the normal direction of the second light-emitting surface 321 is not parallel to the normal direction of the third light-emitting surface 331, so that the second light-emitting surface 321 and the third light-emitting surface 331 are arranged at different angles in the cavity 103, so that the second light-emitting component 32 and the third light-emitting component 33 can illuminate one side of the second window 102 at different angles, so as to fully supplement the light on one side of the second window 102 and improve the supplementary light effect of the second light-emitting component 32 and the third light-emitting component 33 on one side of the second window 102.

[0047] like Figure 2 As shown, in some embodiments of this application, the first light-emitting component 31 is located on a first side of the image acquisition trajectory 201 of the camera 2 in a first direction within the cavity 103, and the second light-emitting component 32 and the third light-emitting component 33 are located on a second side of the image acquisition trajectory 201 in a first direction within the cavity 103. Thus, the first light-emitting component 31 is arranged in an area suitable for avoiding the second light-emitting component 32 and the third light-emitting component 33, and it is convenient to arrange the optical glass assembly 4 in the first direction on the side of the first light-emitting component 31 adjacent to the second light-emitting component 32 and the third light-emitting component 33.

[0048] Furthermore, the second light-emitting component 32 and the third light-emitting component 33 are arranged vertically at intervals within the cavity 103, and the second light-emitting component 32 and the third light-emitting component 33 can supplement light to one side of the second window 102 at different illumination angles.

[0049] like Figure 2As shown, in some embodiments of this application, the first light-emitting component 31 has a first light-concentrating element 312, which is disposed adjacent to the first light-emitting surface 311 of the first light-emitting component 31, and the first light-concentrating element 312 is used to direct the first light beam toward the optical glass component 4 to improve the effect of the first light-emitting component 31 irradiating the optical glass component 4 with the first light beam.

[0050] like Figure 2 As shown, in some embodiments of this application, the second light-emitting component 32 has a second light-concentrating element 322, which is used to direct the second light beam toward the second window 102 to improve the uniformity of the second light beam irradiated by the second light-emitting component 32 toward one side of the second window 102.

[0051] like Figure 2 As shown, in some embodiments of this application, the third light-emitting component 33 has a third light-concentrating element 332, which is used to direct the third light beam toward the second window 102 to improve the uniformity of the third light beam irradiated by the third light-emitting component 33 toward one side of the second window 102.

[0052] It is understandable that the first light-emitting component 31, the second light-emitting component 32, and the third light-emitting component 33 can all be provided with a light-concentrating structure to improve the uniformity of light and thus improve the illumination effect of light on the second window 102 side.

[0053] In a further embodiment of this application, the first light-concentrating element 312, the second light-concentrating element 322 and the third light-concentrating element 332 can all be constructed as light-concentrating rods, and light can pass through the light-concentrating rods and be uniformly irradiated outwards.

[0054] like Figure 2 As shown, in some embodiments of this application, the first light-emitting component 31 further includes a diffuse reflective transparent glass 314, which is arranged downstream of the first light-concentrating element 312. Light passing through the first light-concentrating element 312 can irradiate the diffuse reflective transparent glass and then irradiate the optical glass component 4 through the diffuse reflective transparent glass 314.

[0055] It should be noted that the second light-emitting component 32 and the third light-emitting component 33 may also be equipped with diffuse reflective transparent glass. Figure 2 (not shown in the image) to enhance the illumination effect of the second light-emitting assembly 32 and the third light-emitting assembly 33 on one side of the second window 102.

[0056] like Figure 2As shown, in some embodiments of this application, the first light-emitting component 31 is provided with a first heat exchange channel 313 for the passage of a heat exchange medium; the second light-emitting component 32 is provided with a second heat exchange channel 323 for the passage of a heat exchange medium; and the third light-emitting component 33 is provided with a third heat exchange channel 333 for the passage of a heat exchange medium.

[0057] Taking the first heat exchange channel as an example, when the heat exchange medium flows through the first heat exchange channel, it can exchange heat with the first light-emitting component 31 through the heat exchange medium, so as to remove the heat of the first heat exchange component and achieve heat dissipation and cooling of the first light-emitting component 31.

[0058] It is understood that the substrate of the light-emitting components (such as the first light-emitting component 31, the second light-emitting component 32 and the third light-emitting component 33 mentioned above) can be made of materials with good thermal conductivity, such as aluminum. The heat exchange channels mentioned above (such as the first heat exchange channel 313, the second heat exchange channel 323 and the third heat exchange channel 333 mentioned above) can be formed on the substrate of the light-emitting channel. When the heat exchange medium flows through the substrate, it can transfer the heat of the light-emitting components to achieve heat dissipation and cooling of the light-emitting components, which helps to improve the service life of the light-emitting components.

[0059] like Figure 1 As shown, in some embodiments of this application, the housing 1 is provided with a first heat exchange interface 104 and a second heat exchange interface 105. The first heat exchange interface 104 is connected to the first heat exchange channel 313, the second heat exchange channel 323, and the third heat exchange channel 333, and is used to supply heat exchange medium to the first light-emitting component 31, the second light-emitting component 32, and the third light-emitting component 33. The second heat exchange interface 105 is connected to the first heat exchange channel 313, the second heat exchange channel 323, and the third heat exchange channel 333, and is used to discharge the heat exchange medium flowing through the first light-emitting component 31, the second light-emitting component 32, and the third light-emitting component 33. Thus, the heat exchange medium can circulate, enabling continuous heat dissipation and cooling of the light-emitting components.

[0060] It should be noted that the first heat exchange channel 313, the second heat exchange channel 323, and the third heat exchange channel 333 can be connected in series or in parallel between the first heat exchange interface 104 and the second heat exchange interface 105, as long as the flow of the heat exchange medium is satisfied. The type of heat exchange medium can be a gas, liquid, or other fluid, such as air; no specific limitation is made here.

[0061] In some embodiments of this application, the first light emitted by the first light-emitting component 31 includes infrared light. The first light-emitting component may be composed of an LED light bead board capable of emitting infrared light, so that the first light-emitting component can emit infrared light.

[0062] It should be noted that the first light source may also include white light, that is, the first light source includes both white light and infrared light. In other words, the first light-emitting component 31 may also be composed of an LED bead board that can emit infrared light and an LED bead board that can emit white light.

[0063] It is understandable that infrared light has strong penetrating power, meaning it can pass through the ink on the surface of the circuit board 200, allowing the camera 2 to clearly capture images of defects under the ink, so that inspectors can analyze and judge the subtle defects under the ink.

[0064] In some embodiments of this application, the second light emitted by the second light-emitting component 32 is white light. The second light-emitting component may be composed of a coaxial LED light-emitting board arranged at equal intervals and capable of emitting white light.

[0065] In some embodiments of this application, the third light emitted by the third light-emitting component 33 is white light. The third light-emitting component may be composed of a coaxial LED light-emitting board arranged at equal intervals and capable of emitting white light.

[0066] It should be noted that the above-mentioned structure of the light-emitting component can satisfy multiple requirements at the same time to improve the supplementary lighting effect to the second window 102 side.

[0067] like Figure 2 As shown, the visual inspection combined light source device 100 further includes a first air supply device 51 and a second air supply device 52. The first air supply device 51 is disposed in the housing 1 and is used to supply air to the first light-emitting component 31 to remove heat from the first light-emitting component 31. The second air supply device 52 is disposed in the housing 1 and is used to supply air to at least one of the second light-emitting component 32 and the third light-emitting component 33 to remove heat from the second light-emitting component 32 and the third light-emitting component 33.

[0068] It is understood that the first air supply device 51 and the second air supply device 52 can be configured as fans to supply air into the cavity 103 and carry heat out of the cavity 103 through the air, thereby reducing the temperature of the cavity 103 and the light-emitting component and helping to extend the service life of the light-emitting component.

[0069] In some embodiments of this application, the image acquisition trajectory 201 of the camera 2 is tilted relative to the vertical direction, so that the camera 2 can acquire images of the component to be inspected arranged at the second window 102 at a certain tilt angle, thereby enabling the image acquired by the camera 2 to more clearly present the concave or convex structure on the component to be inspected, so as to assist the inspector in judging the defects on the component to be inspected.

[0070] Therefore, by tilting the image acquisition trajectory 201 of camera 2 relative to the vertical direction, the image acquired by camera 2 can better present the contours of depressions or convexities, making it easier for inspectors to judge the defects presented in the image.

[0071] In some embodiments of this application, the housing 1 is provided with a plurality of terminals 6, which are used to connect to an external power source of the visual inspection combined light source device 100 so as to power the light-emitting component through the external power source and realize the supplementary lighting function of the visual inspection combined light source device 100.

[0072] The arrangement of the terminal 6 on the housing 1 can be adapted to the position of the light-emitting component in the cavity 103, and no specific limitation is made here.

[0073] The visual inspection combined light source device 100 according to the embodiments of this application has at least the following advantages compared with the prior art:

[0074] (1) By cooperating with the light-emitting component and the optical glass component 4, supplementary light is provided to one side of the second window 102 to improve the image acquisition clarity of the inspected component near the second window 102 by the camera 2. The area where the foreign objects of different regular shapes (such as: depressions and protrusions) on the surface of the inspected component are located is fully illuminated by the light, so that a clear image showing the tiny defects can be obtained, providing a reliable basis for the judgment of the inspectors.

[0075] (2) The second light-emitting component 32 can emit infrared light, so that the camera 2 can clearly capture the defect image under the ink, so that the inspectors can analyze and judge the minute defects under the ink.

[0076] (3) The visual inspection combined light source device 100 can dissipate heat and cool down by heat exchange medium or air cooling, which can effectively reduce the temperature inside the cavity 103 and extend the service life of the light output component.
