AI Technical Summary
When testing mirror-like objects, the existing testing equipment does not have a light source configuration that is specifically designed for both mirror-like and three-dimensional surfaces, resulting in poor testing performance. Furthermore, the existing testing equipment generates numerous afterimages that are not directly related to the object being tested, making accurate testing difficult.
The detection equipment employs a stacked light source module, including a first ring light source module, a second ring light source module, and an outer coaxial light source. Through reflector design and light configuration, the reflected light forms low-angle diffuse light, high-angle diffuse light, and coaxial light, thus forming a detection image.
It enables accurate detection of mirror surfaces and three-dimensional structures, eliminates afterimages outside the test object, and improves the uniformity and accuracy of detection.

Furthermore, the accompanying drawings of this utility model are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.
[0027] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or features, these components or features should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one feature from another. Furthermore, the term "or" as used in this document should, as appropriate, include any combination of one or more related listed items.
[0028] Please see Figures 1 to 9 As shown, this is one embodiment of the present invention. Figure 1 As shown, this embodiment discloses a light source stacking inspection device 100 for mirror surface inspection and solder ball inspection of a test object 200. That is, the light source stacking inspection device 100 in this embodiment can be applied to the test object 200 having at least one of two different test embodiments: mirror surface and solder ball. Therefore, any inspection device that cannot perform mirror surface inspection or solder ball inspection should be different from the light source stacking inspection device 100 referred to in this embodiment.
[0029] Specifically, in this embodiment, the light source stacked detection device 100 includes a first ring light source module 1, at least one second ring light source module 2 disposed above the first ring light source module 1, an external coaxial light source 3 disposed above the at least one second ring light source module 2, and a camera module 4 disposed above the external coaxial light source 3, but this utility model is not limited thereto.
[0030] Further, the first ring-shaped light source module 1, the at least one second ring-shaped light source module 2, and the outer coaxial light source 3 can be collectively referred to as a light source device in the present embodiment, and are used for the mirror detection and the solder ball detection of the object 200. In addition, the number of the at least one second ring-shaped light source module 2 is one in the present embodiment, but is not limited thereto. For example, in other embodiments not shown in the present disclosure, the light source device can be used alone (e.g., sold) or in combination with other components according to actual needs; or, as shown in Figure 2 , the number of the at least one second ring-shaped light source module 2 can be multiple, and the multiple second ring-shaped light source modules 2 can have the same structure or slightly different structures from each other.
[0031] As shown in Figure 3 , Figure 5 and Figure 6 , the first ring-shaped light source module 1 is arranged above the object 200 in a height direction H by a predetermined distance D, which is 30-100 mm in the present embodiment, but can be adjusted according to actual needs, which is not limited in the present disclosure.
[0032] Further, the first ring-shaped light source module 1 includes a first reflector 11 facing the object 200, and a first light emitting unit 12 arranged adjacent to the bottom of the first reflector 11. In the present embodiment, the first reflector 11 is a hollow truncated cone, and the top of the first reflector 11 forms a first top opening 13, and the bottom of the first reflector 11 forms a first bottom opening 14.
[0033] In addition, the first light emitting unit 12 includes a plurality of first light emitters 121 (e.g., a plurality of light emitting diodes) in the present embodiment, and the plurality of first light emitters 121 are arranged in a ring shape along the bottom of the first reflector 11, and the light emitting direction of the plurality of first light emitters 121 is toward the first reflector 11. Therefore, the first light emitting unit 12 can emit a first light L1 toward the first reflector 11, so as to form a low-angle diffuse light L1a (passing through the first bottom opening 14) by reflection of the first reflector 11 toward the object 200.
[0034] It should be noted that the first reflecting cover 11 can be configured according to design requirements as long as the first light L1 can be reflected by the first reflecting cover 11 to form the low-angle diffuse light L1a. For the purpose of understanding the present embodiment, the first reflecting cover 11 is described in a preferred embodiment. However, the present application is not limited thereto.
[0035] Further, the first reflecting cover 11 has a polygonal cross section in the height direction H, and the first reflecting cover 11 has a plurality of first reflecting surfaces 111 and a plurality of first circular-arc edges 112. Any two adjacent first reflecting surfaces 111 are connected by a first circular-arc edge 112, so as to effectively eliminate the concern of reflection light gathering caused by the direct connection of two first reflecting surfaces 111.
[0036] In the present embodiment, each first reflecting surface 111 is planar and has a first included angle σ1 with a horizontal plane perpendicular to the height direction H, which is less than 80 degrees. However, the present application is not limited thereto. For example, in other embodiments not shown in the present application, the first reflecting surface 111 can be a concave surface or a convex surface according to actual requirements.
[0037] Further, the plurality of first reflecting surfaces 111 includes a plurality of first main reflecting surfaces 111a and a plurality of first auxiliary reflecting surfaces 111b in the present embodiment. Each of the opposite side edges of the first main reflecting surface 111a is connected to the first auxiliary reflecting surface 111b by the first circular-arc edge 112. Each first reflecting surface 111 is generally trapezoidal, and the number of first main reflecting surfaces 111a and the number of first auxiliary reflecting surfaces 111b are each four. The area of each first main reflecting surface 111a can be more than 5 times the area of any first auxiliary reflecting surface 111b. Thus, two first main reflecting surfaces 111a can be connected by the first auxiliary reflecting surface 111b and the two first circular-arc edges 112, so as to effectively eliminate the concern of reflection light gathering caused by the direct connection of two first main reflecting surfaces 111a.
[0038] As Figure 4 , Figure 5 and Figure 7As shown, the second ring-shaped light source module 2 is arranged above the first ring-shaped light source module 1 along the height direction H. In the present embodiment, the bottom of the second ring-shaped light source module 2 can be stacked on the top of the first reflector 11 of the first ring-shaped light source module 1, so that the first top opening 13 of the first ring-shaped light source module 1 falls within the space surrounded by the second ring-shaped light source module 2, but the present application is not limited thereto. For example, in other embodiments not shown in the present application, the second ring-shaped light source module 2 can also be arranged apart from the first ring-shaped light source module 1 along the height direction H.
[0039] The second ring-shaped light source module 2 comprises a second reflector 21 facing the first top opening 13, and a second light emitting unit 22 arranged adjacent to the bottom of the second reflector 21. In the present embodiment, the second reflector 21 is in the shape of a hollow truncated cone, and the top of the second reflector 21 forms a second top opening 23, while the bottom of the second reflector 21 forms a second bottom opening 24.
[0040] Further, the second light emitting unit 22 in the present embodiment comprises a plurality of second light emitters 221 (such as a plurality of light emitting diodes), and the plurality of second light emitters 221 are arranged in a ring shape along the bottom of the second reflector 21, with the light emitting direction of the plurality of second light emitters 221 being towards the second reflector 21. Thus, the second light emitting unit 22 can emit a second light L2 towards the second reflector 21, so as to form a high-angle diffuse light L2a (through the second bottom opening 24 and the first ring-shaped light source module 1) by reflection of the second reflector 21 towards the object 200.
[0041] It should be noted that the structure of the second reflector 21 can be adjusted and changed according to design requirements as long as it can reflect the second light L2 to form the high-angle diffuse light L2a, but for the purpose of understanding the present embodiment, the following content is described with reference to one preferred embodiment of the second reflector 21, but the present application is not limited thereto.
[0042] Further, the second reflector 21 is in the shape of a polygon in a cross section perpendicular to the height direction H, and the second reflector 21 has a plurality of second reflecting surfaces 211 and a plurality of second circular-arc edge lines 212, and any two adjacent second reflecting surfaces 211 are connected by one second circular-arc edge line 212, so as to effectively eliminate the concern of reflection light gathering that may be caused by the direct connection of two second reflecting surfaces 211.
[0043] In the embodiment, each of the second reflecting surfaces 211 is planar, and has a second included angle σ2 of less than 80 degrees with the horizontal plane perpendicular to the height direction H, but the present application is not limited thereto. For example, in other embodiments not shown in the present application, the second reflecting surfaces 211 can be concave or convex according to actual requirements.
[0044] Further, the second reflecting surfaces 211 include, in the embodiment, second main reflecting surfaces 211a and second auxiliary reflecting surfaces 211b, and opposite edges of each of the second main reflecting surfaces 211a are connected to the second auxiliary reflecting surfaces 211b by the second arcuate edges 212. Each of the second reflecting surfaces 211 is generally trapezoidal, and the number of the second main reflecting surfaces 211a and the number of the second auxiliary reflecting surfaces 211b are each four, and the area of each of the second main reflecting surfaces 211a can be more than 5 times the area of each of the second auxiliary reflecting surfaces 211b. In this way, the second auxiliary reflecting surfaces 211b and the second arcuate edges 212 between the second main reflecting surfaces 211a can effectively eliminate concerns about the concentration of reflected light rays caused by the direct connection of the second main reflecting surfaces 211a.
[0045] In addition, the first reflecting cover 11 and the second reflecting cover 21 preferably have generally similar configurations in the embodiment to facilitate uniform light distribution. For example, the first arcuate edges 112 of the first reflecting cover 11 overlap the second arcuate edges 212 of the second reflecting cover 21 along the height direction H. That is, the first reflecting surfaces 111 generally correspond to the second reflecting surfaces 211 along the height direction H.
[0046] Further, as shown in Figure 5 When the first light L1 of the first ring-shaped light source module 1 has the same light intensity as the second light L2 of the second ring-shaped light source module 2, the first included angle σ1 can be greater than the second included angle σ2 to make the light intensity of the low-angle diffuse light L1a and the light intensity of the high-angle diffuse light L2a more consistent, but the present application is not limited thereto.
[0047] For example, as shown in Figure 8As shown, when the first included angle σ1 and the second included angle σ2 adopt the same angle according to actual requirements (for example, the first ring-shaped light source module 1 and the second ring-shaped light source module 2 adopt the same structure to reduce production cost), the light intensity of the first light L1 adopted by the first ring-shaped light source module 1 must be adjusted to be less than the light intensity of the second light L2 adopted by the second ring-shaped light source module 2. That is, the second included angle σ2 can be adjusted between 0% and 100% of the first included angle σ1 according to design requirements.
[0048] It should be additionally noted that the cross section of the first reflector 11 and the cross section of the second reflector 21 are both illustrated as being in the shape of a truncated pyramid in this embodiment, but the utility model is not limited thereto. For example, in other embodiments not shown in the utility model, at least one of the cross section of the first reflector 11 and the cross section of the second reflector 21 can adopt the shape of a truncated cone according to actual requirements.
[0049] As shown in Figures 5 to 7 , and Figure 9 The outer coaxial light source 3 is arranged adjacent to the second top opening 23, and the outer coaxial light source 3 can emit a coaxial light L3 through the second reflector 21 and the first reflector 11 towards the object to be measured 200. In this embodiment, the outer coaxial light source 3 can be used in combination with the second ring-shaped light source module 2 to reinforce the coaxial light L3 by the high-angle diffuse light L2a, thereby enabling the outer coaxial light source 3 to adopt a smaller size model.
[0050] Furthermore, based on the fact that the outer coaxial light source 3 can be a smaller size model in this embodiment, it can be arranged along the height direction H with the first ring-shaped light source module 1 and the second ring-shaped light source module 2, thereby enabling the light source device to greatly reduce the overall space width occupied.
[0051] The camera module 4, for example, includes a camera 41 and a corresponding lens 42, and the camera module 4 is arranged above the outer coaxial light source 3 along the height direction H. In this embodiment, the camera module 4, the first ring-shaped light source module 1, the second ring-shaped light source module 2, and the outer coaxial light source 3 can be fixed together by a support 5, but the utility model is not limited thereto.
[0052] Moreover, the camera module 4 can be used to acquire light reflected from the object 200 during the mirror detection operation or the solder ball detection operation to form a detection image P, and a gray scale difference between any two points in the detection image P is not greater than 20 gray scale values. Further, the gray scale difference between any two points in the detection image P is preferably not greater than 10 gray scale values, but is not limited thereto.
[0053] As described above, the light source stacked detection device 100 and the light source apparatus can be used in various combinations of the first annular light source module 1, the second annular light source module 2, and the outer coaxial light source 3 according to actual needs, so as to effectively make the detection image P have better uniformity and facilitate the mirror detection operation and the solder ball detection operation.
[0054] In another aspect, the architecture of the light source stacked detection device 100 not only reduces the space width, but also can be used in various combinations of the first annular light source module 1, the second annular light source module 2, and the outer coaxial light source 3 according to actual needs, so as to be suitable for detecting various test requirements.
[0055] For example, the detection image P can be formed by the camera module 4 receiving the high-angle diffuse light L2a and the coaxial light L3 reflected from the object 200. Alternatively, the detection image P can be formed by the camera module 4 receiving the low-angle diffuse light L1a, the high-angle diffuse light L2a, and the coaxial light L3 reflected from the object 200. In this embodiment, the detection image P does not have imaging corresponding to the first light emitting unit 12 or the second light emitting unit 22, so as to facilitate the relevant detection of the object 200 through the detection image P.
[0056] Further, the detection image P includes a center detection area P1, an inner ring detection area P2 surrounding the outside of the center detection area P1, and an outer ring detection area P3 surrounding the outside of the inner ring detection area P2. The center detection area P1 is formed by the camera module 4 receiving the coaxial light L3 reflected from the object 200, the inner ring detection area P2 is formed by the camera module 4 receiving the high-angle diffuse light L2a reflected from the object 200, and the outer ring detection area P3 is formed by the camera module 4 receiving the low-angle diffuse light L1a reflected from the object 200.
[0057] Furthermore, no gap is formed between any two of the center detection area P1, the inner ring detection area P2, and the outer ring detection area P3 adjacent to each other; that is, there can be a local overlap between any two of the center detection area P1, the inner ring detection area P2, and the outer ring detection area P3 adjacent to each other.
[0058] [Technical effects of the embodiments of the utility model]
[0059] In summary, the light source stacking type detection equipment and the light source device disclosed by the embodiments of the utility model can be used arbitrarily according to actual needs by the configuration of the first ring-shaped light source module and the second ring-shaped light source module and further matched with the outer coaxial light source, so as to effectively make the detection image present better uniformity and facilitate the mirror detection operation and the solder ball detection operation.
[0060] The above disclosed content is only the preferred feasible embodiment of the utility model, and does not limit the patent range of the utility model, so that any equivalent technical change made by applying the content of the utility model specification and drawings is included in the patent range of the utility model.
