[0043] In view of the aforementioned deficiencies in existing adjustable combination 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, actively conducted research and innovation in order to create a solution to the deficiencies in the existing technology and make the adjustable combination light source more practical. After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value was finally created.

[0044] Please refer to Figures 1 to 5 This utility model embodiment provides an adjustable combined light source, including a sliding adjustment plate 1 and a strip light source 2.

[0045] The sliding adjustment plate 1 serves as a support and limiter. The sliding adjustment plate 1 has a first arc-shaped sliding adjustment groove 11 and a second arc-shaped sliding adjustment groove 12, both of which surround the same set center line 100. A strip light source 2 is installed on the sliding adjustment plate 1 and emits light towards the set center line 100. At least two strip light sources 2 are installed at intervals in the first arc-shaped sliding adjustment groove 11 and at least two strip light sources 2 are installed at intervals in the second arc-shaped sliding adjustment groove 12. The strip light sources 2 can slide along the first arc-shaped sliding adjustment groove 11 or along the second arc-shaped sliding adjustment groove 12 to adjust their position. In this embodiment, the strip light source 2, with one end located in the first arc-shaped sliding adjustment groove 11, can slide along the first arc-shaped sliding adjustment groove 11, and the strip light source 2, with one end located in the second arc-shaped sliding adjustment groove 12, can slide along the second arc-shaped sliding adjustment groove 12. The position and light emission angle of the strip light source 2 can be adjusted according to actual needs, so that the strip light source 2 can rotate around the set center line to illuminate different sides of the workpiece 01 to be tested, thereby improving the applicability of the combined light source.

[0046] It should also be noted that the bending radii of the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 can be the same or different. Figure 1 In this embodiment, the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 have the same bending radius. When the bending radii of the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 are different, for example, the bending radius of the second arc-shaped sliding adjustment groove 12 is greater than the bending radius of the first arc-shaped sliding adjustment groove 11, then the second arc-shaped sliding adjustment groove 12 can extend to one side of the top of the first arc-shaped sliding adjustment groove 11 and partially surround the first arc-shaped sliding adjustment groove 11. The strip light source 2, which is slidably installed in the second arc-shaped sliding adjustment groove 12, can slide to one side of the top of the first arc-shaped sliding adjustment groove 11 and emit light towards the workpiece 01 to be tested, thereby making the light emitted from the left side significantly stronger. In this embodiment, the light emission effect is more diverse and can be applied to the detection needs of different workpieces 01 to be tested.

[0047] Optionally, the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 are symmetrical about the first symmetry plane 200; in this case, the bending radii of the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 are the same, i.e. Figure 1 As shown. The interval between the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 forms a detection through hole, and the detection through hole is located directly above the set center line 100. The formation of the detection through hole facilitates detection by the detection camera 5 and avoids the possibility of the strip light source 2 blocking the light.

[0048] Optionally, two sliding adjustment plates 1 are provided; the two ends of some strip light sources 2 can be slidably connected to different first arc-shaped sliding adjustment grooves 11, and the two ends of other strip light sources 2 can be slidably connected to different second arc-shaped sliding adjustment grooves 12. The two sliding adjustment plates 1 enable the strip light sources 2 to better maintain their current position and improve the installation stability of the strip light sources 2.

[0049] Optionally, the bar light source 2 is parallel to the set center line 100. After the bar light source 2 is adjusted by sliding, it remains parallel to the set center line 100, thereby making the light spot projected onto the workpiece 01 to be measured more uniform and neat.

[0050] Optionally, such as Figure 1 , Figure 4 and Figure 5 As shown, the first arc-shaped sliding adjustment groove 11 includes a first sliding groove 111 and a second sliding groove 112, both of which are arc-shaped and parallel to each other. The second arc-shaped sliding adjustment groove 12 includes a third sliding groove 121 and a fourth sliding groove 122, both of which are arc-shaped and parallel to each other. The strip light source 2 has two sliding parts. For the strip light source slidably connected to the first arc-shaped sliding adjustment groove 11, one sliding part is located in the first sliding groove 111, and the other sliding part is located in the second sliding groove 112. For the strip light source slidably connected to the second arc-shaped sliding adjustment groove 12, one sliding part is located in the third sliding groove 121, and the other sliding part is located in the fourth sliding groove 122.

[0051] Optionally, the minimum distance from the first arc-shaped sliding adjustment groove 11 to the set center line 100 is A, and the minimum distance from the second arc-shaped sliding adjustment groove 12 to the set center line 100 is B, where A > B. That is, the bending radii of the first arc-shaped sliding adjustment groove 11 and the second arc-shaped sliding adjustment groove 12 are different, reducing the possibility of positional conflict between the strip light source 2 in the first arc-shaped sliding adjustment groove 11 and the strip light source 2 in the second arc-shaped sliding adjustment groove 12.

[0052] Optionally, the two opposite ends of the two sliding adjustment plates 1 are fixedly connected by side plates 3, and the two sliding adjustment plates 1 are parallel to each other, so as to improve the fixing effect between the two sliding adjustment plates 1 and make the structure more stable.

[0053] Optionally, the adjustable combined light source also includes a connecting base plate 4; two sliding adjustment plates 1 are respectively connected to opposite ends of the connecting base plate 4, and the connecting base plate 4 is perpendicular to the side plate 3; one connecting base plate 4 abuts against the side of one side plate 3 to further improve structural stability.

[0054] Optionally, one of the sliding adjustment plates 1 is provided with mounting connection holes to facilitate connection with other racks.

[0055] Example 2

[0056] This embodiment discloses a visual inspection device, including an inspection camera 5 and an adjustable combined light source as described in any one of Embodiment 1. The inspection camera 5 is mounted on the top side of a sliding adjustment plate 1, and the sliding adjustment plate 1 is parallel to the central axis of the inspection camera 5. The inspection camera 5 includes a lens and a camera body. The mounting structure of the lens and camera body is a common structure in the art, and therefore will not be described in detail.

[0057] 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.
