[0034] Please refer to Figure 1 The light source rotating trigger mechanism 100 provided by the utility model is applied to light source testing, provides different wavelength light sources to the excitation module 32, and performs testing.
[0035] The light source rotating trigger mechanism 100 comprises a base 10, a light source assembly, a rotating disc 30 and a switch assembly 40. The light source assembly is fixedly arranged on the base 10. The light source assembly comprises a multi-channel light source 20. The rotating disc 30 is rotationally arranged on the base 10. The rotating disc 30 is provided with a plurality of excitation modules 32. The plurality of excitation modules 32 are circumferentially arranged around the axis of the rotating disc 30. The rotating disc 30 rotates so that the multi-channel light source 20 is selectively corresponding to one of the excitation modules 32. It can be understood that the correspondence between the multi-channel light source 20 and the excitation module 32 means that the light emitted by the multi-channel light source 20 is directed to the excitation module 32.
[0036] Specifically, in the embodiment, the light emission direction of the multi-channel light source 20 is arranged along the radial direction of the rotating disc 30. When the rotating disc 30 rotates, the excitation modules 32 are sequentially rotated to the light emission path of the multi-channel light source 20, and the light emitted by the multi-channel light source 20 is excited through the excitation modules 32, thereby testing.
[0037] Further, in order to switch the wavelength of the multi-channel light source 20, the rotating disc 30 is fixedly provided with a trigger piece 36. The switch assembly 40 comprises a plurality of switch pieces 42. The plurality of switch pieces 42 are circumferentially fixedly arranged around the axis of the rotating disc 30. The switch pieces 42 are correspondingly arranged with the excitation modules 32, and the switch pieces 42 correspond to the plurality of channels of the multi-channel light source 20 respectively. The rotating disc 30 rotates so that the trigger piece 36 selectively triggers one of the switch pieces 42. The switch piece 42 is used to turn on or off the multi-channel light source 20.
[0038] It can be understood that the corresponding arrangement of the switch piece 42 and the excitation module 32 means that the angle of the circumferential array of the switch piece 42 around the axis of the rotating disc 30 is the same as the angle of the circumferential array of the excitation module 32 around the axis of the rotating disc 30. For example, in the embodiment, the number of the excitation modules 32 is three, and the lines connecting the excitation modules 32 and the axis of the rotating disc 30 are 120° apart. Correspondingly, the number of the switch pieces 42 is three, and the lines connecting the switch pieces 42 and the axis of the rotating disc 30 are 120° apart. Moreover, when the trigger piece 36 triggers the switch piece 42, one of the excitation modules 32 corresponding to the switch piece 42 is just located on the light emission path of the multi-channel light source 20.
[0039] It can be easily understood that the corresponding arrangement of the switch piece 42 and the excitation module 32 means that: when the trigger piece 36 triggers one of the switch pieces 42, one of the channels of the multi-channel light source 20 is turned on, thereby emitting light with a first preset wavelength; when the trigger piece 36 triggers another switch piece 42, another channel of the multi-channel light source 20 is turned on, thereby emitting light with a second preset wavelength. By triggering different switch pieces 42 through the trigger piece 36, the multi-channel light source 20 emits light with different wavelengths, which facilitates the rapid switching of the light source and meets the testing requirements.
[0040] Please refer to Figure 2Specifically, a plurality of mounting areas 31 are arranged on the rotating disc 30. The plurality of mounting areas 31 are arranged in a circumferential direction of an axis of the rotating disc 30, and the distance between the mounting areas 31 is the same. The excitation module 32 is detachably mounted on the mounting area 31.
[0041] By arranging the mounting area 31, the excitation module 32 is detachably mounted on the rotating disc 30, so that different excitation modules 32 can be detached or replaced, facilitating testing. At the same time, the number and position of the excitation module 32 can be adjusted. The light source rotating triggering mechanism 100 has high flexibility and can meet the requirements of different light source testing.
[0042] Further, the light source rotating triggering mechanism 100 further comprises a limiting assembly. The limiting assembly comprises a limiting protrusion 35 and a plurality of limiting grooves 33. The limiting protrusion 35 is fixedly arranged on the base 10. The limiting protrusion 35 is located on one side of the rotating disc 30 and faces the rotating disc 30. The plurality of limiting grooves 33 are arranged on the edge of the rotating disc 30. The limiting grooves 33 are arranged corresponding to the mounting areas 31. When the limiting protrusion 35 is engaged with one of the limiting grooves 33, the light source assembly corresponds to one of the mounting areas 31.
[0043] It can be understood that the limiting grooves 33 are arranged corresponding to the mounting areas 31, that is, the number of the limiting grooves 33 is the same as the number of the mounting areas 31. The angle between the connecting line of the limiting grooves 33 and the axis of the rotating disc 30 is the same as the angle between the connecting line of the mounting areas 31 and the axis of the rotating disc 30. When the limiting protrusion 35 is located in one of the limiting grooves 33, one of the mounting areas 31 is located on the light path of the multi-channel light source 20.
[0044] By arranging the limiting protrusion 35 and the limiting groove 33 in cooperation, when the rotating disc 30 is rotated and the corresponding excitation module 32 is located on the light path of the multi-channel light source 20, the limiting protrusion 35 is located in the limiting groove 33, at this time, a greater force is required to rotate the rotating disc 30, and then switch to the next excitation module 32, which can improve the rotating feeling of the rotating disc 30, prompt the excitation module 32 to be in place, and thus perform testing.
[0045] Optionally, in the embodiment, the number of installation areas 31 is six, and three installation areas 31 are provided with excitation modules 32. The angle between the adjacent two installation areas 31 and the axis of the rotating disc 30 is 60°. The angle between the adjacent two limiting grooves 33 and the axis of the rotating disc 30 is 60°. The angle between the adjacent two excitation modules 32 and the axis of the rotating disc 30 is 120°. In other embodiments, the number of installation areas 31 and limiting grooves 33 can be set as required, and the utility model does not limit this. Further, in other embodiments, the number of excitation modules 32 can also be set as required, and the excitation modules 32 can also not be arranged uniformly, for example, four excitation modules 32 are arranged, etc. As long as the multi-channel light source 20 can correspond to the excitation module 32, the utility model does not limit this.
[0046] Still further, the limiting assembly further comprises a mounting seat 34 and an elastic piece. The mounting seat 34 is fixedly arranged on the base 10. The limiting block 35 is arranged on the mounting seat 34. The elastic piece is arranged between the mounting seat 34 and the limiting block 35. It can be understood that by arranging the elastic piece, the limiting block 35 has a tendency to move towards the rotating disc 30, so that the limiting block 35 always abuts against the edge of the rotating disc 30, and further, the limiting block 35 can be clamped into the limiting groove 33.
[0047] In other embodiments, the structure of the elastic piece can also not be adopted, and the limiting block 35 itself can also adopt an elastic structure, for example, rubber, etc. By the elasticity of the limiting block 35 itself, one end of the limiting block 35 abuts against the edge of the rotating disc 30.
[0048] Please refer to Figure 3 The switch assembly 40 further comprises a trigger plate 41. The trigger plate 41 is fixedly arranged on the base 10. The trigger plate 41 is located on the side of the rotating disc 30 away from the excitation module 32. The switch piece 42 is fixedly arranged on the side of the trigger plate 41 towards the rotating disc 30. By arranging the trigger plate 41, the switch piece 42 can be positioned on one side of the rotating disc 30.
[0049] Further, the trigger plate 41 is provided with a mounting hole. The switch piece 42 is detachably connected with the trigger plate 41 through the mounting hole. It can be understood that since the excitation module 32 in the embodiment adopts a modular design, the switch piece 42 can be adjusted according to the number and position of the excitation module 32.
[0050] Still further, the trigger piece 36 is protrudingly arranged on the surface of the rotating disc 30 towards the trigger plate 41. The switch piece 42 is provided with a switch groove 43 matched with the trigger piece 36. It can be understood that when the rotating disc 30 rotates, the trigger piece 36 rotates with the rotating disc 30, and sequentially rotates into the switch groove 43 of different trigger pieces 36, so as to emit signals, so that different channels of the multi-channel light source 20 are turned on, and different wavelengths of light are emitted.
[0051] Specifically, in the embodiment, the switch member 42 can adopt a laser reflection sensor. The trigger member 36 is in a sheet structure. When the trigger member 36 is located in the switch groove 43 of the switch member 42, the switch member 42 blocks the laser of the switch member 42, and the switch member 42 thus emits an opening signal, and the controller controls the multi-channel light source 20 to realize the adjustment of the light source of different wavelengths.
[0052] In other embodiments, the switch member 42 can adopt other types of sensors or switches as long as the trigger signal can be realized, and the utility model is not limited thereto.
[0053] Specifically, the trigger plate 41 and the rotating disc 30 are both circular discs. The trigger plate 41 and the rotating disc 30 are coaxially arranged. The trigger plate 41 is provided with mounting holes. The mounting holes are circumferentially and uniformly arranged around the axis of the trigger plate 41. The number of the mounting holes is the same as that of the mounting areas 31.
[0054] Please continue to refer to Figure 1 In order to facilitate the rotating connection of the rotating disc 30 and the base 10, the base 10 is fixedly provided with a bearing seat 11. The bearing seat 11 is sleeved with a bearing 12. The rotating disc 30 is rotatably installed on the bearing seat 11.
[0055] Further, in order to facilitate the rotation of the rotating disc 30 by the tester, the base 10 is provided with a notch. When it is needed to switch the excitation module 32 and the corresponding light source, the rotating disc 30 can be manually rotated through the notch.
[0056] The beneficial effects of the light source rotating trigger mechanism 100 of the utility model include:

The rotating disc 30 is provided with a plurality of excitation modules 32. The plurality of excitation modules 32 are circumferentially arranged around the axis of the rotating disc 30. The rotating disc 30 rotates to make the multi-channel light source 20 selectively correspond to one of the excitation modules 32. The rotating disc 30 is fixedly provided with a trigger member 36. The switch assembly 40 includes a plurality of switch members 42. The plurality of switch members 42 are circumferentially arranged around the axis of the rotating disc 30.

[0058] When the rotating disc 30 rotates, different excitation modules 32 can be switched to correspond to the multi-channel light source 20, and the trigger 36 can trigger different switch pieces 42 respectively, so that the multi-channel light source 20 emits light of different wavelengths, and then excites the excitation module 32 corresponding to the light source to test. The utility model can quickly switch different wavelength light sources and excitation modules 32, meet the test requirements, without setting multiple light sources, reduce the space occupation of equipment.
