[0002] The current light source device includes a housing and a lamp board installed in the housing. The lamp board emits light outwards along the opening of the housing, and the lamp board and the housing are fixedly connected. This results in that once the housing is fixed, the color and direction of the light emitted by the lamp board are both unadjustable, so the applicable range is small. In particular, the existing light sources cannot meet the lighting requirements of different areas of a workpiece that need to be irradiated with different color lights respectively.

[0003] In view of this, it is necessary to design a light source device and a detection device to meet the lighting requirements of irradiating different areas of a workpiece with different color lights.

After continuous research, design, and repeated sample making and improvement, the present utility model with practical value has finally been created.

[0046] Please refer to Figures 1 to 4, an embodiment of the present utility model provides a light source device, including: an optical fiber main line 1; a white light point source 2, installed at the light incident end of the optical fiber main line 1, for injecting white light into the optical fiber main line 1; a splitter 3, installed at the light output end of the optical fiber main line 1, and a plurality of branch optical fibers 31 for outputting light are installed on the splitter 3; a bendable shaping tube 32 is arranged on the outer periphery of the branch optical fiber 31; a filter device 4, a filter device 4 is arranged at the light output end of each bendable shaping tube 32, and filter sheets 41 of specific colors are installed in different filter devices 4. It should also be noted that shading layers are arranged on the outer peripheries of the optical fiber main line 1 and the branch optical fibers 31.

[0047] Specifically, the white light point source 2 injects light into the optical fiber main line 1, and the optical fiber main line 1 guides the light into the splitter 3 and divides it into several beams and guides it to each branch optical fiber 31. The light is emitted from the branch optical fiber 31 and is emitted onto a specific surface of the workpiece after passing through the filter device 4. In actual detection, the color of the filter sheet 41 in the filter device 4 can be set according to actual needs, that is, light of different colors can be emitted onto the surface of the workpiece. In addition, the bending curvature of different bendable shaping tubes 32 can be reasonably adjusted, so as to change the bending degree of each branch optical fiber 31, so that light of a specific color is emitted in a specific direction onto a specific area of the workpiece. Generally, there are areas of different colors on the surface of the workpiece, and corresponding color light is required to irradiate different areas to meet the detection needs.

[0048] In a specific implementation manner, the surface of the workpiece is a hemispherical surface, then each bendable shaping tube 32 needs to be bent reasonably so that each filter device 4 is arranged in a spherical shape, and the light output ports of the filter devices 4 face the surface of the workpiece. In addition, each filter device 4 can also be arranged in an arc shape, a linear shape or a planar shape, etc.

[0049] Optionally, the filter device 4 includes a fixed cylinder 42 installed at the light output end of the bendable shaping tube 32 and a filter sheet 41 detachably installed in the fixed cylinder 42.

[0050] Specifically, the filter sheet 41 can be removed according to actual needs, and then a filter sheet 41 of a specific color can be replaced. The filter sheet 41 of a specific color can be a red, yellow, blue, green or other color filter sheet 41.

[0051] Optionally, as Figure 5As shown, the filter device 4 includes a fixed cylinder 42 mounted on the light-emitting end of the bendable and shaped tube 32 and a filter assembly 43 mounted in the fixed cylinder 42; the fixed cylinder 42 is formed with a light-emitting hole 4301 for light to pass through and a U-shaped groove 4302 for storing the filter assembly 43, and the U-shaped groove 4302 intersects with the light-emitting hole 4301; the filter assembly 43 includes a plurality of filter plates 41 connected in sequence, and at least two first positioning magnets 44 are arranged on the filter plate 41, and a second positioning magnet 45 for adsorbing the corresponding first positioning magnet 44 is also arranged on the fixed cylinder 42; when the second positioning magnet 45 adsorbs the corresponding first positioning magnet 44, the adsorbed and fixed filter plate 41 filters the light emitted from the light-emitting hole 4301. The light-emitting end of the branch optical fiber 31 is inserted into the light-emitting hole 4301.

[0052] Specifically, in the light source device of this embodiment, the positions of different filter plates 41 are adjusted, so that the first positioning magnets 44 on the filter plate 41 of a specific color are positioned and adsorbed by the corresponding second positioning magnets 45, thereby adjusting the light-emitting color. Preferably, in the filter assembly 43, the colors of two adjacent filter plates 41 are different. It should also be noted that two additional groups of side attracting magnets can be additionally provided. When the second positioning magnet 45 adsorbs the first positioning magnet 44 on the filter plate 41, the side attracting magnets can well adsorb two adjacent other filter plates 41, avoiding the adjacent filter plates 41 from hitting the filter plate 41 adsorbed by the second positioning magnet 45. One group of side attracting magnets, two second positioning magnets 45, and the other group of side attracting magnets are arranged in sequence along the extending direction of the U-shaped groove 4302.

[0053] It should also be noted that filter plates 41 of different colors are in the U-shaped groove 4302. Therefore, in the actual use process, there is no need to take out and replace the new light-shielding plate 41, which greatly reduces the possibility of the light-shielding plate 41 falling and being damaged during the assembly process, and avoids the possibility of not being able to find the light-shielding plate 41, making the replacement of the light-shielding plate 41 more convenient. For example Figure 5 , the fixed cylinder 42 is provided with an arc-shaped curved surface, so that the filter plate 41 can slide more smoothly to the adsorbed position.

[0054] It should be particularly supplemented that since the first positioning magnet 44 and the second positioning magnet 45 can roughly fix the filter plate 41 in a suitable position when they adsorb each other, and the filter plate 41 does not need to be positioned very precisely to achieve light filtering, as long as the light-emitting hole 4301 is completely shielded, the structure in this embodiment is practical, that is, only the corresponding first positioning magnet 44 and second positioning magnet 45 need to adsorb each other to fix a filter plate 41 to a relatively suitable position.

[0055] Optionally, the filter component 43 further includes a first adjustment cord 46 and a second adjustment cord 47, and adjacent two filter plates 41 are connected by a connecting cord 48. Both the first adjustment cord 46 and the second adjustment cord 47 extend out of the fixed cylinder 42. The first adjustment cord 46 is connected to a filter plate 41 at one end, and the second adjustment cord 47 is connected to the filter plate 41 at the other end.

[0056] Specifically, in this embodiment, by pulling the first adjustment cord 46 or the second adjustment cord 47, different filter plates 41 can be adsorbed by the second positioning magnet 45. It should also be noted that the first adjustment cord 46 or the second adjustment cord 47 can also be pulled to reasonably adjust the filter plate 41 adsorbed by the second positioning magnet 45 to make the position of the filter plate 41 more appropriate.

[0057] Optionally, the white light point source 2 includes a circuit board 21, white light beads 22 mounted on the circuit board 21, and a condenser module 23 mounted on the light-emitting side of the white light beads 22. The light-emitting end of the condenser module 23 faces the light-incident end of the optical fiber main line 1.

[0058] Optionally, a light-incident groove 101 is formed at the light-incident end of the optical fiber main line 1. The condenser module 23 at least includes a condenser lens extending into the light-incident groove 101. The light-incident groove 101 can effectively reduce the possibility of light leakage, enabling more light to enter the optical fiber main line 1.

[0059] Optionally, the white light point source 2 further includes a cooling device 24 for cooling the circuit board 21.

[0060] Optionally, the filter device 4 is detachably sleeved on the light-emitting end of the bendable shaping tube 32. Specifically, since the filter device 4 is detachable, the entire filter device 4 can be directly replaced to achieve the purpose of changing the light-emitting color, that is, removing the old filter device 4 and replacing it with a new one.
