[0037] As described in the background art, there are still many problems in the automatic optical inspection of lead frames, which will be described in detail below.

[0038] At present, defects to be detected, such as contamination, foreign objects, horizontal deformation, poor electroplating, etc., are mainly detected by coaxial light. Coaxial light is usually used as the main light source for appearance defect detection due to its clear imaging, uniform brightness, and distinct contours. However, for defects with a certain height difference, or defects with no obvious difference when viewed directly, such as scratches, vertical deformation, and abnormal electroplating surface. Since the brightness of coaxial light is too uniform, it may weaken the difference and cause such defects to be missed. Therefore, in the current detection process, it is often necessary to add a strip light source with an inclined angle to strengthen the defects with height differences, thereby reducing the occurrence of missed defects.

[0039] However, adding additional tilted angle light sources on the detection production line will not only increase the cost, but also the space on the detection production line is limited. The additional tilted angle light sources often cannot be fixed in the optimal position. In addition, since the various light sources are not enclosed in the same cavity, external light is likely to cause interference, and the light itself is also likely to leak out, thereby affecting the detection effect.

[0040] On this basis, the present invention provides a combined light source device, which can effectively reduce the space area occupied by the multiple combined light sources by integrating several light source components in the first cavity of the first box body, so that each light source component has a better irradiation position, and can reduce external light interference and the problem of its own light leakage, thereby improving the detection effect. The integrated multiple combined light source can reduce the common components in the split structure, thereby effectively reducing the cost. In addition, each of the light source components has an independent electrical control system, which can be flexibly adjusted and controlled according to actual needs.

[0041] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Typical embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] Figure 1 is a schematic diagram of the structure of a combined light source device without a third light source assembly and in use in one embodiment of the present invention; Figure 2 It is a schematic diagram of the structure of a combined light source device with a third light source assembly in one embodiment of the present invention and in a state of use.

[0044] Please refer to Figure 1 A combined light source device comprises: a first box body 10, wherein the first box body 10 has a first cavity 101; a plurality of light source components arranged in the first cavity 101, wherein the light source components are used to generate light, and the light has a light path irradiated onto an object to be detected 15; the light paths generated in different light source components are different; and each light source component has an independent electrical control system.

[0045] In this embodiment, by integrating several of the light source assemblies in the first cavity 101 of the first box body 10, the space area occupied by the multiple-combination light source can be effectively reduced, so that each light source assembly has a better irradiation position, and can reduce external light interference and the problem of self-light leakage, thereby improving the detection effect. The integrated multiple-combination light source can reduce the common components in the split structure, thereby effectively reducing the cost. In addition, each of the light source assemblies has an independent electrical control system, which can be flexibly adjusted and controlled according to actual needs.

[0046] In this embodiment, the electrical control system of each light source assembly is used to control the switch and light brightness of the corresponding light source assembly, and can flexibly adjust the opening, closing and light intensity of the corresponding light source assembly as needed.

[0047] Please continue to refer to Figure 1 , the plurality of light source assemblies include: a first light source assembly 11 and a plurality of second light source assemblies 12; the first light source assembly 11 is used to generate a first light ray 111, the first light ray 111 has a first light path S1 irradiated onto the object to be detected 15; the second light source assembly 12 is used to generate a second light ray 121, the second light ray 121 has a second light path S2 irradiated onto the object to be detected 15, and an angle α is formed between the second light path S2 and the first light path S1; the angle α between the second light path S2 generated in different second light source assemblies 12 and the first light path S1 is different.

[0048] Please continue to refer to Figure 1 In this embodiment, the first light path S1 and the upper image generating device 16 used in conjunction with the combined light source device are on the same axis.

[0049] In this embodiment, the first light source assembly 11 is placed above a plurality of the second light source assemblies 12 .

[0050] It should be noted that, in the present embodiment, the upper image generating device 16 may specifically adopt a CCD (charge coupled device) camera. Since the first light path S1 and the upper image generating device 16 are on the same axis, the first light 111 may be called coaxial light. Several second light paths S2 have different angles α with the first light path S1, so several second light rays 121 may be called side light.

[0051] In this embodiment, the first light 111 and the second light 121 are used to detect the front side of the object to be detected 15. When the first light 111 and the second light 121 irradiate the front side of the object to be detected 15, they will be reflected, and the reflected light will be captured by the upper image generating device 16, thereby realizing the front side detection of the object to be detected 15.

[0052] Please continue to refer to Figure 1 In this embodiment, the first light source assembly 11 includes: a first light source 112, used to generate the first light 111; a first mirror reflection component 113, used to refract the first light 111 once or multiple times so that the first light 111 is irradiated onto the object to be detected 15 along the first light path S1.

[0053] In this embodiment, the second light source assembly 12 includes: a second light source 122 for generating the second light 121; a second mirror reflection component 123 for refracting the second light 121 once or multiple times so that the second light 121 is irradiated onto the object to be detected 15 along the second light path S2.

[0056] In this embodiment, the third light path S3 and the lower image generating device 17 used in conjunction with the combined light source device are located on the same axis.

[0057] It should be noted that, in this embodiment, the lower image generating device 17 can specifically adopt a CCD camera. Since the third light path S3 is on the same axis as the lower image generating device 17 and is used to detect the back side of the object to be detected 15, the third light 141 can be called backlight.

[0058] Please continue to refer to Figure 2 It should be noted that, in this embodiment, when backlight detection is required, part of the third light 141 will pass through the gap in the object to be detected 15, and then be captured by the lower image generating device 17, so that the back of the object to be detected 15 appears in a backlight state, thereby realizing back detection of the object to be detected 15. During backlight detection, only the third light 141 emitted by the combined light source device located above can be used, or the first light 111 and / or the second light 121 emitted by the combined light source device located below can be used.

[0059] In this embodiment, the third light source assembly 14 includes: a third light source 142, used to generate the third light 141; a third mirror reflection component 143, used to refract the third light 141 once or multiple times so that the third light 141 is irradiated onto the object to be detected 15 along the third light path S3.

[0060] In this embodiment, the object to be detected 15 includes: a lead frame.

[0062] The difference from the above embodiment is that the several light source components in the combined light source device described in this embodiment are detachably connected.

[0063] Please refer to Figure 3A combined light source device comprises: a plurality of light source assemblies, wherein the light source assemblies are used to generate light, and the light has a light path that irradiates an object 25 to be detected; the light paths generated in different light source assemblies are different; the plurality of light source assemblies can be used independently or in combination, and when used in combination, the plurality of light source assemblies are connected in sequence in a detachable manner, and the light of the plurality of light source assemblies is generated in the same cavity; each of the light source assemblies has an independent electrical control system.

[0064] In this embodiment, by integrating and detachably connecting several light source assemblies, the space occupied by the multi-combination light source can be effectively reduced, so that each light source assembly has a better irradiation position, and can reduce external light interference and the problem of its own light leakage, thereby improving the detection effect. The integrated multi-combination light source can reduce the common components in the split structure, thereby effectively reducing the cost. In addition, each of the light source assemblies has an independent electrical control system, which can be flexibly adjusted and controlled according to actual needs.

[0065] In this embodiment, the electrical control system of each light source assembly is used to control the switch and light brightness of the corresponding light source assembly, and can flexibly adjust the opening, closing and light intensity of the corresponding light source assembly as needed.

[0069] It should be noted that, in the present embodiment, the upper image generating device 26 may specifically adopt a CCD camera.

[0070] In this embodiment, the first light 211 and the second light 221 are used to detect the front side of the object to be detected 25. When the first light 211 and the second light 221 irradiate the front side of the object to be detected 25, they will be reflected, and the reflected light will be captured by the upper image generating device 26, thereby realizing the front side detection of the object to be detected 26.
