[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.

[0030] The light-emitting components include multiple light-emitting components, such as the first light-emitting component 31, the second light-emitting component 32, the third light-emitting component 33, and the fourth light-emitting component 34. The light-emitting components can emit light to provide supplementary lighting to one side of the component being inspected. Multiple optical glass components are also arranged, such as the first optical glass component 41, the second optical glass component 42, and the third optical glass component 43. The optical glass components can be used to guide, diffuse, and reflect the light emitted by the light-emitting components, so that the light can be directed to one side of the second window 102, thereby improving the supplementary lighting effect on the component being inspected arranged on one side of the second window 102.

[0031] Reference Figure 2 As shown, the housing 1 has a cavity 103 for arranging the light assembly and the optical glass assembly. 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 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. This improves the presentation effect of the concave and convex structures on the surface of the component to be inspected on the side of the acquired image in the image, making it easier for the operator to accurately judge the defects on the component to be inspected based on the image.

[0032] Reference Figure 2As shown, the first light-emitting component 31 and the second optical glass component 42 are arranged in the cavity 103. The first light emitted by the first light-emitting component 31 can be directed toward the first optical glass component 41, and the first light can be guided by the first optical glass component 41 to one side of the second window 102, so that the first light can illuminate the detected component arranged near the second window 102, thereby improving the supplementary lighting effect on the detected component.

[0033] Reference Figure 2 As shown, the second light-emitting component 32, the third light-emitting component 33, and the second optical glass component 42 are also arranged in the cavity 103. The second light emitted by the second light-emitting component 32 and the third light emitted by the third light-emitting component 33 can be directed toward the second optical glass component 42, and the second and third light rays can be guided by the second optical glass component 42 to one side of the second window 102, so that the second and third light rays can illuminate the detected component arranged near the second window 102, thereby improving the supplementary lighting effect on the detected component.

[0034] Reference Figure 2 As shown, the fourth light-emitting component 34 and the third optical glass component 43 are both arranged inside the cavity 103. The fourth light emitted by the fourth light-emitting component 34 can be directed toward the third optical glass component 43, and the fourth light is guided by the third optical glass component 43 to one side of the second window 102, so that the fourth light can illuminate the detected component arranged near the second window 102, thereby improving the supplementary lighting effect on the spare part side component.

[0035] It is understood that the visual inspection combined light source device 100 in this application, through the cooperation of light-emitting components (such as the first light-emitting component 31, the second light-emitting component 32, the third light-emitting component 33, and the fourth light-emitting component 34 mentioned above) and optical glass components, can achieve supplementary lighting to one side of the second window 102. This provides sufficient supplementary lighting to the surface of the inspected component during image acquisition by the camera 2, making the image acquired by the camera 2 clearer and ensuring image clarity. This helps inspectors accurately detect minor defects on the inspected component based on the image acquired by the camera 2. Specifically, the better the image quality acquired by the camera 2, the higher the accuracy of defect judgment on the inspected component.

[0036] 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.

[0037] 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 circuit board 200 as an example, after the circuit board 200 undergoes a tin plating process, the surface of the circuit board 200 will exhibit 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 inspection personnel.

[0038] Furthermore, the image acquisition trajectory 201 in this application is arranged at an angle relative to the vertical direction. That is, the image acquisition trajectory 201 of the camera 2 has a certain angle with the vertical direction, so that the camera 2 acquires images in a non-perpendicular manner to the second window 102. Thus, the images acquired by the camera 2 can better present the depressions or protrusions on the surface of the inspected component, further improving the image acquisition effect of the visual inspection combined light source device 100.

[0039] like Figure 2 As shown, the component to be inspected is arranged outside the housing 1 and near the second window 102. The light-emitting assembly and the optical glass assembly can work together to provide supplementary light to the component to improve the clarity of the image acquired by the visual inspection combined light source device 100. The component to be inspected is typically arranged horizontally so that the surface to be inspected is fully presented at the image acquisition module of the camera 2.

[0040] 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.

[0041] In this application, the light-emitting component and the optical glass component work together 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 fully illuminating the area where different regular-shaped foreign objects (such as depressions and protrusions) are located on the surface of the inspected component, a clear image showing minute defects can be obtained, providing a reliable basis for the inspection personnel's judgment. At the same time, the image acquisition trajectory 201 of the camera 2 is set at an angle relative to the vertical direction, so that the image acquired by the camera 2 can better show the contour of the depression or protrusion, making it easier for the inspection personnel to judge the defects presented in the image.

[0042] Reference Figure 2As shown, in some embodiments of this application, the angle between the image acquisition trajectory 201 of the camera 2 and the vertical direction is within the range of 5°-20°, preferably 13°. The camera 2 can be fixed by a clamping mechanism to maintain the position of the camera 2 relative to the housing 1.

[0043] like Figure 2 As shown, in some embodiments of this application, the second window 102 is horizontally arranged, the first light-emitting component 31 has a first light-emitting surface 311, the first light is emitted from the first light-emitting surface 311, and the angle between the first light-emitting surface 311 and the horizontal plane is α, and satisfies the relationship: 80°≤α≤100°.

[0044] The first optical glass assembly 41 is disposed on the light-emitting side of the first light-emitting assembly 31. The light emitted through the first light-emitting surface 311 can be directed to the first optical glass assembly 41, and the first optical glass assembly 41 can guide the first light to the second window 102 to supplement the light to the detected component and improve the image acquisition effect of the camera 2 on the detected component.

[0045] It should be noted that the first optical glass assembly 41 can be constructed as a high-definition semi-transparent and semi-reflective optical glass assembly, thereby reflecting the first light beam toward the second window 102 through the first optical glass assembly 41. When the angle α between the first light-emitting surface 311 and the horizontal plane meets the above parameter range, it facilitates the arrangement of the first light-emitting assembly 31 in the cavity 103 and can ensure the supplementary lighting effect toward the second window 102.

[0046] In some embodiments of this application, the first light-emitting component 31 can be fixed at a certain position in the cavity 103. That is, the angle between the first light-emitting surface 311 and the horizontal plane is kept fixed. At this time, the reflection position of the first light can be adjusted by adjusting the angle of the first optical glass component 41 so as to guide the first light to a position suitable for illuminating the component being tested.

[0047] It is understood that the first light-emitting component 31 can also be rotatably arranged within the cavity 103. That is, the tilt angle between the first light-emitting surface 311 and the horizontal plane can be adjusted by rotating the first light-emitting component 31, so as to adjust the first light-emitting surface 311 to a position suitable for cooperating with the first optical glass component 41. The first light-emitting component 31 and the first optical glass component 41 can be fixed in the cavity 103 by clamping mechanism or by bolts or other connecting parts. No specific limitation is made here, as long as it can satisfy the requirement that the first light beam is guided to one side of the second window 102 through the first light-emitting component 31 and the first optical glass component 41 to achieve supplementary lighting.

[0048] like Figure 2 As shown, in some embodiments of this application, the second light-emitting component 32 has a second light-emitting surface 321, the third light-emitting component 33 has a third light-emitting surface 331, and the included angle between the second light-emitting surface 321 and the third light-emitting surface 331 is β, which satisfies the relationship: 135°≤β≤165°.

[0049] The second light-emitting surface 321 and the third light-emitting surface 331 are both used to emit light (i.e., the second light and the third light mentioned above) to one side of the second optical glass assembly 42. The second optical glass assembly 42 can be constructed as a high-brightness linear optical glass assembly (e.g., diffuse reflection transparent glass) to reflect light to one side of the second window 102 (e.g., diffuse reflection) through the second optical glass assembly 42 to supplement the light to the detected component arranged at the second window 102.

[0050] When the angle between the second light-emitting surface 321 and the third light-emitting surface 331 meets the above parameter range, the incident light amount at the second optical glass assembly 42 can be effectively guaranteed to ensure the supplementary lighting effect at the detected component, and it also facilitates the arrangement of the second light-emitting assembly 32 and the third light-emitting assembly 33 in the cavity 103. It is understood that if the angle β between the second light-emitting surface 321 and the third light-emitting surface 331 is too large or too small, it may cause a waste of light energy.

[0051] like Figure 2 As shown, in some embodiments of this application, the second window 102 is horizontally arranged, the fourth light-emitting component 34 has a fourth light-emitting surface 341, the angle between the fourth light-emitting surface 341 and the horizontal plane is γ, and satisfies the relationship: 30°≤γ≤65°.

[0052] The third optical glass assembly 43 is disposed on the light-emitting side of the fourth light-emitting assembly 34. The light emitted from the fourth light-emitting surface 341 can be directed to the third optical glass assembly 43, and the third optical glass assembly 43 can guide the fourth light to the second window 102 to supplement the light to the detected component and improve the image acquisition effect of the camera 2 on the detected component.

[0053] It should be noted that the third optical glass assembly 43 can be constructed as a high-brightness linear light source glass assembly (e.g., diffuse reflection transparent glass), so that the fourth light can be reflected to one side of the second window 102 through the third optical glass assembly 43. When the angle γ between the fourth light-emitting surface 341 and the horizontal plane meets the above parameter range, the supplementary lighting effect to one side of the second window 102 can be guaranteed, and the arrangement of the fourth light-emitting assembly 34 in the cavity 103 can be facilitated.

[0054] Combination Figure 1 and Figure 2As shown, in the vertical direction, at least a portion of the second optical glass assembly 42 is disposed opposite to the second window 102, and at least a portion of the third optical glass assembly 43 is disposed opposite to the second window 102.

[0055] Reference Figure 2 In a specific embodiment of this application, the first light-emitting component 31 is arranged on one side near the first window 101, and the first light-emitting component 31 is located in the area above the second light-emitting component 32 and the third light-emitting component 33 in the cavity 103. Moreover, the first light-emitting component 31 is adapted to avoid the first window 101, so as to avoid the first light-emitting component 31 being arranged on the image acquisition trajectory 201 and affecting the image acquisition effect of the camera 2.

[0056] Furthermore, the angled opening formed by the second light-emitting surface 321 and the third light-emitting surface 331 faces towards the second window 102, and the second optical glass assembly 42 is located between the light-emitting sides of the second light-emitting assembly 32 and the third light-emitting assembly 33 and the second window 102, so as to provide supplementary lighting for the detected component by directing the second and third light rays toward the second window 102 through the second optical glass assembly 42. Simultaneously, the fourth light-emitting assembly 34 is arranged near the second window 102, and the third optical glass assembly 43 is located between the fourth light-emitting assembly 34 and the third optical glass assembly 43, so as to provide supplementary lighting for the detected component by directing the fourth light rays toward the second window 102 through the third optical glass assembly 43.

[0057] like Figure 2 As shown, in some embodiments of this application, the first light-emitting component 31, the second light-emitting component 32, and the third light-emitting component 33 are located on a first side of the image acquisition trajectory 201 of the camera 2 in a first direction, and the fourth light-emitting component 34 is located on a second side of the image acquisition trajectory 201 in the first direction. Therefore, the first light-emitting component 31, the second light-emitting component 32, the third light-emitting component 33, and the fourth light-emitting component 34 can avoid obstructing the image acquisition trajectory 201, ensuring the image acquisition effect of the camera 2 on the detected component.

[0058] Reference Figure 2 The first light-emitting component 31, the second light-emitting component 32, and the third light-emitting component 33 are arranged on the same side of the image acquisition trajectory 201, and the first light-emitting component 31 is arranged above the second light-emitting component 32 and the third light-emitting component 33, so that the first light-emitting component 31 is arranged in an area in the cavity 103 that is suitable for avoiding the second light-emitting component 32 and the third light-emitting component 33.

[0059] Understandably, the first light emitted by the first light-emitting component 31 is directed toward the first optical glass component 41 and reflected by the first optical glass component 41 toward the second window 102. Preferably, the path of the light reflected by the first optical glass component 41 coincides with the image acquisition trajectory 201 to improve the supplementary lighting effect of the first light and to ensure that the reflected light avoids other light-emitting components (such as the second light-emitting component 32 and the fourth light-emitting component 34), thus guaranteeing the supplementary lighting effect.

[0060] like Figure 2 As shown in a further embodiment of this application, the second optical glass assembly 42 and the third optical glass assembly 43 are respectively disposed on both sides of the image acquisition trajectory 201 in the first direction, thereby facilitating the arrangement of the second optical glass assembly 42 in the area corresponding to the second light-emitting assembly 32 and the third light-emitting assembly 33, and the arrangement of the third optical glass assembly 43 in the area corresponding to the fourth light-emitting assembly 34, and enabling the first optical glass assembly 41 and the second optical glass assembly 42 to avoid the image acquisition trajectory 201, thus ensuring the image acquisition effect of the camera 2.

[0061] like Figure 1 As shown, in some embodiments of this application, the housing 1 is provided with a first fixing groove 11, which passes through the side wall of the housing 1 in the second direction, and the second optical glass assembly 42 is retractably engaged with the first fixing groove 11, thereby selectively mounting the second optical glass assembly 42 on the housing 1.

[0062] The first fixing groove 11 connects the outside of the housing 1 to the cavity 103, allowing the second optical glass assembly 42 to be pulled out from the outside of the housing 1. This facilitates cleaning of the second optical glass assembly 42 (e.g., removing dust deposits on its surface), making the operation simple and convenient. Simultaneously, the first fixing groove 11 guides the pulling action of the second optical glass assembly 42, improving its reliability and stability during the pulling process.

[0063] like Figure 1 As shown, in some embodiments of this application, the housing 1 is provided with a second fixing groove 12, which is disposed through the side wall of the housing 1 in the second direction, and the third optical glass assembly 43 is retractably engaged with the second fixing groove 12, thereby selectively mounting the third optical glass assembly 43 on the housing 1.

[0064] The second fixing groove 12 connects the outside of the housing 1 to the cavity 103, allowing the third optical glass assembly 43 to be pulled out from the outside of the housing 1. This facilitates cleaning of the third optical glass assembly 43 (e.g., removing dust deposits on its surface), making the operation simple and convenient. Simultaneously, the second fixing groove 12 guides the pulling action of the third optical glass assembly 43, improving its reliability and stability during the pulling process.

[0065] It is understood that the housing 1 can simultaneously have a first fixing groove 11 and a second fixing groove 12, thereby enabling the simultaneous assembly and disassembly of the second optical glass assembly 42 and the third optical glass assembly 43. This facilitates cleaning of the second optical glass assembly 42 and the third optical glass assembly 43, ensuring their light reflection performance. Furthermore, the first fixing groove 11 and the second fixing groove 12 are spaced apart in the first direction of the housing 1, thus preventing interference between the second optical glass assembly 42 and the third optical glass assembly 43.

[0066] In some embodiments of this application, the first light emitted by the first light-emitting component 31 is white light, so as to supplement white light to one side of the second window 102 through the first light-emitting component 31. The first light-emitting component may be composed of a coaxial LED light bead board arranged at equal intervals and capable of emitting white light.

[0067] In some embodiments of this application, the second light emitted by the second light-emitting component 32 includes infrared light, and the third light emitted by the third light-emitting component 33 is white light. The second light-emitting component may be composed of an LED bead board capable of emitting infrared light, and the third light-emitting component 33 may be composed of an LED bead board capable of emitting white light, thus enabling the third light-emitting component to emit white light.

[0068] It should be noted that the second light source may also include white light, that is, the second light source includes both white light and infrared light. In other words, the second light-emitting component 32 may also be composed of an LED bead board that can emit infrared light and an LED bead board that can emit white light.

[0069] 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.

[0070] In some embodiments of this application, the fourth light emitted by the fourth light-emitting component 34 is white light. The fourth light-emitting component may be composed of a coaxial LED light-emitting board arranged at equal intervals and capable of emitting white light.

[0071] Among them, the above-mentioned structure of the light-emitting component can simultaneously satisfy multiple requirements to improve the supplementary lighting effect to one side of the second window 102.

[0077] like Figure 2As shown in a further embodiment of this application, the visual inspection combined light source device 100 further includes an air supply device 5. The air supply device 5 is disposed on the housing 1 and is used to supply air into the cavity 103 so that the air in the cavity 103 is discharged through the airflow formed by the air supply device 5.

[0081] 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:

[0082] (1) By cooperating with the light-emitting component and the optical glass component, supplementary light is provided to one side of the second window 102 to improve the image acquisition clarity of the detected 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 detected component are fully illuminated by the light, so as to obtain a clear image showing the tiny defects and provide a reliable basis for the judgment of the inspectors.

[0083] (2) The image acquisition trajectory 201 of the camera 2 is tilted relative to the vertical direction, so that the image acquired by the camera 2 can better present the contour of the depression or convexity, making it easier for the inspector to judge the defects presented in the image.

[0084] (3) 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 subtle defects under the ink.

[0085] (4) The visual inspection combined light source device 100 is equipped with an air supply device 5, which can effectively reduce the temperature inside the cavity 103 and extend the service life of the light output component.
