[0047] Example 1

[0048] In view of the aforementioned deficiencies in existing combined light sources, the applicant, based on years of extensive practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, has actively conducted research and innovation in order to create a solution that overcomes the shortcomings of existing technologies and makes the combined light source more practical. Through continuous research and design, and after repeated prototype production and improvements, this utility model, which possesses genuine practical value, has finally been created.

[0049] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 This utility model embodiment provides a combined light source, including a fixed block 1, two sliding blocks 2, a first annular light source 3, and a second annular light source 4. The fixed block 1 is provided with a groove 11, and the sliding blocks 2 are slidably installed in the groove 11. One sliding block 2 is detachably connected to the first annular light source 3, and the other sliding block 2 is detachably connected to the second annular light source 4. The two sliding blocks 2 can be installed in the same groove 11 or in different grooves 11. The center lines of the first annular light source 3 and the second annular light source 4 are parallel to the extending direction of the groove 11. The fixed block 1 is provided with two fixing slots 12 that extend through the groove 11, and the two fixing slots 12 are spaced apart. Fixing members can be inserted into the fixing slots 12 to fix the sliding blocks 2.

[0050] In this embodiment, the sliding block 2 is slidably installed in the groove 11 of the fixing block 1, and the first annular light source 3 and the second annular light source 4 are respectively installed on one of the sliding blocks 2. The sliding block 2 can slide along the groove 11 to a suitable position, and then the fixing member can be inserted along the fixing groove 12 to fix the sliding block 2, thereby fixing the sliding block 2 in the appropriate position, that is, completing the position adjustment of the first annular light source 3 and the second annular light source 4. In this embodiment, the first annular light source 3 and the second annular light source 4 are adjusted and fixed through a clever structure, which can achieve the purpose of flexibly adjusting the position between the first annular light source 3 and the second annular light source 4, thereby flexibly adjusting the illumination position of the light, and thus providing better illumination for workpieces of different types and sizes.

[0051] Optionally, the fixing element is a fixing block 5 that can be embedded in the fixing groove 12; the end of the sliding block 2 near the fixing groove 12 is provided with a fixing hole 21, and a fixing post 51 is provided corresponding to the fixing hole 21. The fixing block 5 is embedded in the fixing groove 12 and the fixing post 51 is inserted into the fixing hole 21, thereby fixing the sliding block 2. If the position needs to be adjusted, the fixing block 5 can be replaced. The fixing post 51 on different fixing holes 5 has different positions, thereby achieving the purpose of adjusting the position of the sliding block 2. Alternatively, the fixing element can also be a rod, a plug of other shapes, etc., for example, a rod that passes through the sliding block 2 and is fixed to the fixing block 1.

[0052] In another specific embodiment, a row of fixing holes 21 is provided at the end of the sliding block 2 near the fixing groove 12. When the fixing block 5 is inserted into the fixing groove 12, the fixing post 51 is inserted into one of the fixing holes 21 to fix the sliding block 2.

[0053] Optionally, the fixing groove 12 is an oblong groove, with its centerline parallel to the extension direction of the sliding groove 11. The cross-section of the sliding block 2 matches the shape of the fixing groove 12, and the sliding block 2 is symmetrical about a vertical plane. Specifically, after the sliding block 2 is rotated 180°, it can be inserted into the fixing groove 12, and the fixing post 51 is located in another symmetrical position, thereby reducing the size of the custom-made sliding block 2.

[0054] Optionally, the combined light source also includes a base plate 61, a coaxial light source 7, a camera 8, a first support plate 91 for supporting the coaxial light source 7, and a second support plate 92 for supporting the camera 8; the fixing block 1, the first support plate 91, and the second support plate 92 are all detachably mounted on the base plate 61; along the first direction, the fixing block 1, the first support plate 91, and the second support plate 92 are arranged sequentially at intervals. Figure 2 The first direction is from left to right.

[0055] In this embodiment, the base plate 61 is used to position the fixing block 1, the first support plate 91, and the second support plate 92, thereby completing the positioning of the "first ring light source 3 and the second ring light source 4", the coaxial light source 7, and the camera 8. The base plate 61 actually serves as a support and positioning element.

[0056] Optionally, such as Figure 3 and Figure 4 As shown, the combined light source also includes a support frame 62, a corner coaxial light source 71, a camera 8, a first support plate 91 for supporting the corner coaxial light source 71, and a second support plate 92 for supporting the camera 8. The fixing block 1, the first support plate 91, and the second support plate 92 are all detachably mounted on the support frame 62. Along the optical path direction, the fixing block 1, the first support plate 91, and the second support plate 92 are arranged sequentially at intervals. The support frame 62 includes a vertical portion 621 and a horizontal portion 622; the fixing block 1 constitutes the vertical portion 621 and is perpendicular to the horizontal portion 622. In this embodiment, the corner coaxial light source 71 enables the detection of a workpiece 100 in another direction, thus expanding the applicability of the combined light source.

[0057] Optionally, the end of the fixing block 1 is provided with an elastic part, and the fixing groove 12 has a number of grooves spaced apart on the side wall near the fixing block 1. The shape of the grooves matches the shape of the elastic part. The elastic part is inserted into different grooves to initially fix the fixing block 1 in a suitable position. Then, a fastener can be inserted, which can be more convenient, i.e., there is no need to manually tighten the fixing block 1.

[0058] Optionally, both the first annular light source 3 and the second annular light source 4 are provided with a lamp plate 32 that is inclined relative to the center line of the first annular light source 3; the first annular light source 3 and the second annular light source 4 emit light to the same side, and the light emitted from the second annular light source 4 passes through the inner hole of the first annular light source 3 and illuminates the surface of the workpiece. It should be noted that the distance between the first annular light source 3 and the second annular light source 4 is different, thereby changing the light emission effect and adapting to the detection needs of workpieces 100 of different sizes.

[0059] Optionally, the first annular light source 3 includes an annular frame 31, several lamp panels 32, and partition blocks 33. The lamp panels 32 are mounted on the inner annular surface of the annular frame 31. The annular frame 31 is provided with a through mounting groove, and the partition blocks 33 are inserted into the through mounting groove to separate two adjacent lamp panels 32. The opposite sides of the partition blocks 33 abut against the two lamp panels 32 respectively. In this embodiment, the partition blocks 33 can better separate adjacent lamp panels 32 and facilitate accurate fixing of the lamp panels 32.
