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

[0043] Please refer to Figures 1 to 2, an embodiment of the present utility model provides a light source device with adjustable light output color, including: a white light source 1; a dimming plate 2 disposed on the light output side of the white light source 1, and a plurality of light filtering through holes 21 are provided on the dimming plate 2. A light filtering sheet 22 is installed in each light filtering through hole 21 to filter light. Different light filtering sheets 22 are installed in different light filtering through holes 21, and at least one light filtering through hole 21 is not installed with a light filtering sheet 22; a position adjustment device 3 is installed on one side of the white light source 1 for adjusting the position of the dimming plate 2 so that different light filtering through holes 21 face the white light source 1.

[0044] For example, a red light filtering sheet 22 is provided in one light filtering through hole 21, a yellow light filtering sheet 22 is provided in another light filtering through hole 21, and a blue light filtering sheet 22 is provided in the third light filtering through hole 21. When the light output of the light source device with adjustable light output color is required to be red light, the position of the dimming plate 2 is adjusted by the position adjustment device 3 so that the light filtering through hole 21 installed with the red light filtering sheet 22 faces the white light source 1. After the light emitted by the white light source 1 passes through the red light filtering sheet 22, only the red light passes through the red light filtering sheet 22 and irradiates the workpiece. Similarly, when the required light output is yellow light, the light filtering through hole 21 installed with the yellow light filtering sheet 22 is made to face the white light source 1. Similarly, when the required light output is blue light, the light filtering through hole 21 installed with the blue light filtering sheet 22 is made to face the white light source 1. Similarly, when the required light output is white light, the light filtering through hole 21 not installed with a light filtering sheet 22 is made to face the white light source 1.

[0045] It should be particularly noted that the number of light filtering through holes 21 is at least three, and can also be four, five or even more.

[0046] Optionally, the position adjustment device 3 includes a rotation driving device 31. The rotation driving device 31 has a driving shaft 311, and the driving shaft 311 is fixedly connected to the dimming plate 2; the driving shaft 311 is perpendicular to the dimming plate 2, and a plurality of light filtering through holes 21 are arranged in a circumferential array around the center line of the driving shaft 311, and adjacent two light filtering through holes 21 are separated from each other. In this embodiment, the rotation driving device 31 drives the dimming plate 2 to rotate to different angles, so as to achieve the purpose of making different light filtering through holes 21 face the white light source 1.

[0047] Optionally, the light source device with adjustable light output color further includes a parallel optical path module 4 and a beam splitter 5; along the light output direction of the white light source 1, the dimming plate 2, the parallel optical path module 4, and the beam splitter 5 are arranged in sequence, and the beam splitter 5 is inclined to reflect the light emitted from the parallel optical path module 4 onto the surface of the workpiece. In this embodiment, the white light source 1 emits light from the light filtering through-hole 21 of the dimming plate 2, and then enters the parallel optical path module 4. The parallel optical path module 4 makes the light more parallel and makes the light shoot towards the beam splitter 5. The beam splitter 5 reflects the light towards the workpiece, thereby illuminating the surface of the workpiece and also achieving the effect of coaxial illumination. The parallel optical path module 4 can effectively improve the effect of illuminating the workpiece.

[0048] Optionally, the parallel optical path module 4 includes a cylinder body 41, and the cylinder body 41 serves to support the first condenser lens 42 and the second condenser lens 43; the first condenser lens 42 and the second condenser lens 43 are installed in the cylinder body 41, and the first condenser lens 42 is installed on the side of the second condenser lens 43 closer to the white light source 1. The first condenser lens 42 and the second condenser lens 43 have a condensing effect, which is used to improve the illuminating effect on the workpiece, so that the surface defects of the workpiece can be more easily detected by photographing.

[0049] Optionally, the light source device with adjustable light output color further includes a light absorbing plate 6. The light absorbing plate 6 is facing the light output port of the cylinder body 41, and the beam splitter 5 is located between the cylinder body 41 and the light absorbing plate 6. The light absorbing plate 6 is used to reduce the influence of stray light and improve the imaging effect of the camera, thereby improving the detection accuracy of the camera.

[0050] Optionally, as Figure 4 , the position adjustment device 3 includes a linear driving device for driving the dimming plate 2 to linearly move along a first set direction; several light filtering through-holes 21 are arranged at intervals along the first set direction. As Figure 4 , in this embodiment, the linear driving device drives the dimming plate 2 to move horizontally, so that different light filtering through-holes 21 are facing the white light source 1. Of course, the first set direction can also be the vertical direction or the inclined direction.

[0051] Optionally, the light source device with adjustable light output color further includes a heat dissipation frame 7. The white light source 1 is installed on one side of the heat dissipation frame 7, and the position adjustment device 3 is installed on the top side of the heat dissipation frame 7. Optionally, the white light source 1 includes a circuit board 11 attached to the heat dissipation frame 7 and white light LED beads 12 arranged on the circuit board 11. The heat dissipation frame 7 can effectively improve the heat dissipation effect and prevent the temperature of the white light source 1 from being too high.

[0052] Optionally, as Figure 3, the light source device with adjustable light output color further includes a lifting device 32 for driving the rotation driving device 31 to lift along a second set direction. The lifting shaft of the lifting device 32 is fixedly connected to the rotation driving device 31; the second set direction is perpendicular to the driving shaft 311; around the center line of the driving shaft 311, at least two circles of light filtering through holes 21 are arranged at intervals on the light adjusting plate 2. Specifically, the lifting device 32 can change the height of the light adjusting plate 2, so that the inner or outer circle of light filtering through holes 21 faces the white light source 1. Cooperating with the rotation driving device 31, more light filtering through holes 21 can be provided, making the color of the light output by the light source device with adjustable light output color richer.

[0053] Optionally, the light source device with adjustable light output color further includes a housing, and the white light source 1, the light adjusting plate 2 and the position adjusting device 3 are all installed in the housing. The housing is used to protect the white light source 1, the light adjusting plate 2 and the position adjusting device 3.
