Technical Field
[0001] This utility model relates to the field of light source structure technology, and in particular to a dual-color coaxial light source. Background Technology
[0002] Coaxial light sources are parallel lights within the category of surface lighting, primarily used to provide parallel illumination for vision systems composed of cameras and lenses. They are particularly suitable for surface feature measurement in machine vision inspection devices. The brightness of a coaxial light source directly affects imaging quality, measurement efficiency, and measurement accuracy.
[0003] Existing coaxial light sources can generally only emit a single color of light. To switch the emitted light color, the entire coaxial light source must be replaced, which requires users to purchase multiple coaxial light sources with different emitted light colors, resulting in high costs. In addition, installing and disassembling the coaxial light source is also quite troublesome, affecting the actual detection efficiency.
[0004] Therefore, it is necessary to design a dual-color coaxial light source that can emit light of at least two different colors, which can help improve detection efficiency.
[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0024] Optionally, a diffuser is installed between the first beam splitter and the second beam splitter;
[0025] The diffuser lens divides the mounting cavity into a first cavity and a second cavity, with the first beam splitter located in the first cavity and the second beam splitter located in the second cavity.
[0026] Optionally, when the support cover is installed on the housing, the first lamp plate is perpendicular to the second lamp plate.
[0027] Optionally, the dual-color coaxial light source further includes a first control unit and a second control unit, wherein the first control unit is controlled and connected to the first lamp panel, and the second control unit is controlled and connected to the second lamp panel.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] The dual-color coaxial light source provided by this utility model allows the first color light emitted from the first lamp panel to pass through the first beam splitter and be directed onto the workpiece under test, thereby illuminating the workpiece and enabling it to be inspected under the illumination of the first color light. Alternatively, the first lamp panel can be turned off, and the second color light emitted from the second lamp panel can pass through the first beam splitter and be directed onto the workpiece under test, thereby illuminating the workpiece and enabling it to be inspected under the illumination of the second color light. Furthermore, the color of the emitted light can be changed by replacing the second lamp panel on the support cover. Replacing the support cover is simpler and easier to implement than replacing the existing coaxial light source, effectively saving replacement time and thus improving inspection efficiency.

[0048] Please refer to Figures 1 to 5 This utility model embodiment provides a dual-color coaxial light source, including:
[0049] The housing 1 forms a mounting cavity, inside which a first beam splitter 11 is installed, and a mounting hole 12 is provided corresponding to the first beam splitter 11; a first lamp plate 2 is installed in the mounting cavity to emit a first color light to the first beam splitter 11; a support cover 3 is detachably mounted on which a second lamp plate 4 that can enter the mounting hole 12 is installed, and the second lamp plate 4 is used to emit a second color light to the first beam splitter 11; the support cover 3 is detachably connected to the housing 1, and the support cover 3 can cover the mounting hole 12. The first lamp plate 2 and the second lamp plate 4 can be opened or closed independently.
[0050] In this embodiment, in the dual-color coaxial light source, the first beam splitter 11 is a semi-transparent and semi-reflective lens. The first color light emitted from the first lamp panel 2 can pass through the first beam splitter 11 and be directed towards the workpiece to be tested, thereby illuminating the workpiece. The workpiece can be detected by the detection camera under the illumination of the first color light. Alternatively, the first lamp panel 2 is turned off, and the second color light emitted from the second lamp panel 4 can pass through the first beam splitter 11 and be directed towards the workpiece to be tested, thereby illuminating the workpiece. The workpiece can be detected by the detection camera under the illumination of the second color light. Therefore, the dual-color coaxial light source in this embodiment can have two different colors of emitted light, which can better meet the detection needs of some workpieces to be tested.
[0051] Furthermore, in this embodiment, the second lamp plate 4 on the support cover 3 can be replaced. Different second lamp plates 4 can emit different colors of light, thereby changing the emitted light color. Replacing the support cover 3 is simpler and easier to implement than replacing the existing coaxial light source, effectively saving replacement time and thus improving detection efficiency.
[0052] In actual operation, if it is necessary to switch the light color, but neither the first light panel 2 nor the second light panel 4 can emit the required light color, only the second light panel 4 with a different light color needs to be replaced. There is no need to replace the entire dual-color coaxial light source, making the replacement operation more convenient.
[0053] It should also be noted that the dual-color coaxial light source also includes a first control unit and a second control unit. The first control unit is connected to the first lamp board 2, and the second control unit is connected to the second lamp board 4.
[0054] Optionally, the first color light emitted by the first light panel 2 is white light; the second color light emitted by the second light panel 4 is infrared light, blue light, yellow light, or green light. It should also be noted that the second color light emitted by the second light panel 4 can also be other colors.
[0055] Optionally, the dual-color coaxial light source also includes a connecting threaded component; the support cover 3 is provided with a connecting through hole, and the housing 1 is provided with a connecting threaded hole corresponding to the connecting through hole. The connecting threaded component passes through the connecting through hole and connects with the connecting threaded hole to press and fix the support cover 3 onto the housing 1. In this embodiment, the support cover 3 is fixed to the housing 1 by the connecting threaded component, and the support cover 3 can be removed simply by loosening the connecting threaded component.
[0056] In another specific implementation, such as Figure 4 and Figure 5 As shown, the support cover 3 is provided with at least three insertion posts 31; the housing 1 is provided with insertion holes 101 corresponding to the insertion posts 31. The insertion post 31 includes a post body 311 and a sealing ring 312 sleeved on the post body 311. The post body 311 is provided with an annular groove 102 for positioning the sealing ring 312. When the insertion post 31 is inserted into the insertion hole 101, the sealing ring 312 abuts against the hole wall of the insertion hole 101 to fix the support cover 3 on the housing 1.
[0057] In this embodiment, the insertion post 31 is inserted into the insertion hole 101, and the sealing ring 312 elastically deforms and abuts against the wall of the insertion hole 101, thereby fixing the support cover 3. The insertion and fixing method using the insertion post 31 and the insertion hole 101 is convenient for both installation and disassembly. It should also be noted that the sealing ring 312 is made of a high-temperature resistant material to improve its service life.
[0058] Optionally, the inner wall of the insertion hole 101 is provided with an annular groove 102 for positioning the sealing ring 312, which can accurately position the installation position of the support cover 3 and improve the installation accuracy of the support cover 3.
[0059] Optionally, the groove wall of the annular groove 102 and the hole wall of the insertion hole 101 are smoothly transitioned, thereby making the entry or exit of the sealing ring 312 into or out of the annular groove 102 smoother. This prevents scratches on the sealing ring 312.
[0060] Optionally, a second beam-splitting lens 13 parallel to the first beam-splitting lens 11 is also installed in the housing 1, and a light-emitting port is provided on the housing 1 corresponding to the second beam-splitting lens 13; a detection window 14 is also provided on the housing 1, the detection window 14 is directly opposite the light-emitting port, and the second beam-splitting lens 13 is located between the detection window 14 and the light-emitting port. In this embodiment, the detection camera detects the illuminated workpiece under test through the detection window 14.
[0061] Optionally, a diffuser 15 is installed between the first beam splitter 11 and the second beam splitter 13; the diffuser 15 divides the mounting cavity into a first cavity and a second cavity, with the first beam splitter 11 located in the first cavity and the second beam splitter 13 located in the second cavity. The diffuser 15 can improve the uniformity of the emitted light.
[0062] Optionally, when the support cover 3 is installed on the housing 1, the first lamp plate 2 is perpendicular to the second lamp plate 4. The first beam splitter 11 is set at an angle of 45°.
[0063] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
