Description

Technical Field

[0001] This invention relates to the field of spectrometers, and particularly to a quantum cascade laser spectrometer. Background Technology

[0002] With the rapid development of optical technology and lasers, lasers are widely used in welding, cutting, laser cleaning, spectral measurement, spectral analysis, gas monitoring and other fields. The power requirements for lasers are also getting higher and higher. Low-power lasers are difficult to meet the requirements. In the field of laser spectrometers, the laser emits laser light, which is then reflected by a mirror. After penetrating the substance being measured, the laser light enters the detector. In the existing laser spectrometers, the laser light is irradiated onto the mirror. The laser mirror can only receive the laser light by manual adjustment, which is slow, inaccurate and inefficient.

[0003] Therefore, a quantum cascade laser spectrometer is needed to solve the above-mentioned technical problems. With the popularization of electric vehicles, wireless charging, as a convenient and safe charging method, is gradually being applied to two-wheeled electric vehicles. Existing wireless charging systems typically include a transmitter and a receiver. The transmitter is responsible for generating an alternating magnetic field, while the receiver receives energy and charges the battery through coil coupling. In traditional systems, the receiver usually includes a DC / DC buck-boost conversion control module to adapt to battery packs of different voltage levels. Summary of the Invention

[0033] The present invention provides a quantum cascade laser spectrometer, comprising a laser spectrometer 11 that emits laser light and a laser reflector 12 located on one side of the laser spectrometer 11 for reflecting laser light. The laser spectrometer 11 emits laser light that irradiates the laser reflector 12, and the laser reflector 12 reflects the laser light back into the laser spectrometer 11 to enhance the laser irradiation intensity of the laser spectrometer 11. The laser spectrometer 11 includes a rotating device 112 and a laser emitting device 111, with the laser emitting device 111 located above the rotating device 112. The rotating device 112 is used to rotate the laser emitting device 111. The laser reflector 12 includes an adjusting device and a reflecting device 121, with the reflecting device 121 located above the adjusting device. The adjusting device is used to adjust the receiving of laser light by the reflecting device 121.

[0034] In this system, the laser from the laser spectrometer 11 is irradiated onto the laser reflector 12. The laser reflector 12 adjusts the position of the reflecting device 121 through an adjustment device, thereby accurately reflecting the laser into the laser spectrometer 11. This enhances the intensity of the laser spectrometer 11, eliminates the need for manual adjustment, speeds up the adjustment process, and makes the adjustment more precise.

[0035] Multiple laser reflectors 12 are provided and are evenly arranged around the laser spectrometer 11. The angle between adjacent laser reflectors 12 and the laser spectrometer 11 is 45°. The laser spectrometer 11 rotates to expand the detection area. The multiple laser reflectors 12 ensure the intensity of the laser from all directions, making the detection results more accurate.

[0036] Please refer to Figure 3 , Figure 3 for Figure 2 The cross-sectional view along section line AA shows that the rotating device 112 includes a first motor 1121, a first radial ball bearing 1122, a second radial ball bearing 1124, and an extension rod 1123. The first radial ball bearing 1122 and the second radial ball bearing 1124 are located at the two ends of the extension rod 1123, respectively. The first motor 1121 is located below the extension rod 1123. The first motor 1121 is used to drive the extension rod 1123 to rotate, and the extension rod 1123 drives the laser emitting device 111 to rotate. The first radial ball bearing 1122 and the second radial ball bearing 1124 are used to stabilize the rotation of the laser emitting device 111, making the detection results of the laser emitting device 111 more accurate when rotating. At the same time, they are used to prevent the laser emitting device 111 from shaking and shifting its position when rotating.

[0037] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the reflection device structure of the quantum cascade laser spectrometer of the present invention. The laser emitting device includes a laser 61, a visible light beam splitter 62 located on one side of the laser 61, a visible light emitter 63 located on the upper part of the visible light beam splitter 62, a first reflecting mirror 64 located on one side of the visible light beam splitter 62, a second reflecting mirror 65 located below the first reflecting mirror 64, a reference sample 66 located on one side of the second reflecting mirror 65, a third reflecting mirror 67 located on one side of the reference sample 66, a collimating lens 68 located on the upper part of the third reflecting mirror 67, a beam splitter 69 located on the upper part of the collimating lens 68, a detector 70 located on one side of the beam splitter 69, and a fourth reflecting mirror 71 located on the upper part of the beam splitter 69. The laser emitting device emits laser light that irradiates the laser reflecting mirror 12, and the laser reflecting mirror 12 reflects the laser light back into the laser emitting device to enhance the laser intensity of the laser emitting device.

[0038] The visible light emitter 63 emits a laser beam that shines on the visible light beam splitter 62. The visible light beam splitter 62 splits the laser beam into two beams that shine on the laser 61 and the first reflector 64 respectively, making it easier to observe the optical path on the first reflector 64 when the detector 70 emits a laser, thereby making it easier to adjust the optical path of the laser emitted by the laser 61.

[0039] The rotating device 112 also includes a plane bearing 1125, which is located between the laser emitting device 111 and the second radial ball bearing 1124. The plane bearing 1125 is used to improve the high load capacity of the rotating device 112, so that the rotating device 112 can withstand greater gravity.

[0040] Please refer to Figure 5 , Figure 5 for Figure 5 for Figure 4 The cross-sectional view along the BB section line shows that the adjustment device includes a lifting component 123 for adjusting the up and down movement of the reflecting device 121, a first rotating component 122 for adjusting the rotation of the reflecting device 121, and a second rotating component 124 for adjusting the angle of the reflecting device 121. The lifting component 123 and the second rotating component 124 are located at the two ends of the first rotating component 122, respectively, to adjust the laser reflector 12 in all directions, so that the laser reflector 12 can quickly and accurately reflect the laser back into the laser spectrometer 11.

[0041] The lifting assembly 123 includes a second motor 1232 and a nut screw 1231. The second motor 1232 drives the first rotating assembly 122 to move up and down through the nut screw 1231. The second rotating assembly 124 includes a third motor 1241 and an L-shaped fixing plate 1242. The third motor 1241 is fixed on the fixing plate 1242. The reflecting device 121 includes an extension plate 1212 and a reflecting part 1211. The reflecting part 1211 and the third motor 1241 are located at opposite ends of the extension plate 1212. The third motor 1241 adjusts the up and down angle of the emitting part through the extension plate 1212. The third motor 1241 is fixedly connected to the fixing plate 1242. The third motor 1241 is connected to the reflecting part 1211 through the extension plate 1212, which facilitates the rotation of the reflecting device 121 by the third motor 1241.

[0042] The first rotating assembly 122 includes a fourth motor, which is rotatably connected to the bottom of the fixed plate 1242. The fourth motor drives the second rotating assembly 124 to rotate by rotating the fixed plate 1242. Since the fixed plate 1242 is L-shaped, it is convenient for the fourth motor to be rotatably connected to the fixed plate 1242. The fourth motor drives the fixed plate 1242 to rotate, so that the fixed plate 1242 drives the reflector 121 to rotate.

[0043] In this embodiment, the first rotating assembly further includes a fixed base 1223 and a connecting plate 1221. The connecting plate 1221 is located on the fixed base 1223, and the fourth motor is fixed in the fixed base 1223 through the connecting plate 1221.

[0044] The rotating device 112 also includes a support plate 1126 and an L-shaped reinforcing plate 1127. The laser emitting device 111 is detachably connected to the support plate 1126 via the reinforcing plate 1127. The reinforcing plate 1127 is used to fix the laser emitting device 111 and also facilitates the disassembly and installation of the laser emitting device 111.

[0045] Working principle:

[0046] Multiple laser reflectors 12 are located around the laser spectrometer 11. The laser spectrometer 11 emits laser light that shines on the laser reflectors 12. The laser reflectors 12 reflect the laser light back into the laser spectrometer 11 to enhance the laser intensity of the laser spectrometer 11. The laser spectrometer 11 expands its detection range by rotating.

[0047] The first radial ball bearing 1122 and the second radial ball bearing 1124 are located at both ends of the extension rod 1123. The first radial ball bearing 1122 and the second radial ball bearing 1124 are used to stabilize the laser emitting device 111. The planar bearing 1125 is located between the second radial ball bearing 1124 and the laser emitting device 111. The planar bearing 1125 is used to increase the load force of the rotating device 112. The first motor 1121 is located below the extension rod 1123, which facilitates the first motor 1121 to drive the extension rod 1123 to rotate, thereby the extension rod 1123 drives the laser emitting device 111 to rotate.

[0048] The second rotating assembly 124 and the lifting assembly 123 are located at both ends of the first rotating assembly 122. The reflecting device 121 is located above the second rotating assembly 124. The lifting assembly 123 is used to drive the first rotating assembly 122 to move up and down. The first rotating assembly 122 drives the laser emitting device 111 to move up and down. The first rotating assembly 122 is used to drive the second rotating assembly 124 to rotate left and right. The second rotating assembly 124 drives the reflecting device 121 to move left and right. The second rotating assembly 124 is used to adjust the angle of the up and down swing of the reflecting device 121.

[0049] First, when the laser spectrometer 11 rotates, the first motor 1121 drives the extension rod 1123 to rotate, and the extension rod 1123 drives the support plate 1126 to rotate. Due to the action of the first radial ball bearing 1122 and the second radial ball bearing 1124, the extension rod 1123 stably drives the support plate 1126 to rotate. The laser emitting device 111 is connected to the support plate 1126 through the reinforcing plate 1127, so that the laser emitting device 111 stably follows the rotation of the support.

[0050] When the laser shines on the laser reflector 12, the laser deviates from the laser reflector 12. The second motor 1232 drives the nut screw 1231 to move the first rotating and fixed assembly up and down, thereby adjusting the vertical position of the reflecting device 121. The fourth motor drives the fixed plate 1242 to rotate. The fourth motor is connected to the bottom of the fixed plate 1242, which is convenient for the fourth motor to drive the fixed plate 1242 to rotate left and right, thereby adjusting the horizontal position of the reflecting device 121. The third motor 1241 drives the extension plate 1212 to rotate. The third motor 1241 drives the extension plate 1212 to swing up and down, thereby adjusting the angle of the reflecting device 121. Through the adjustment of the lifting assembly 123, the first rotating assembly 122 and the second rotating assembly 124, the laser can be stably emitted into the laser spectrometer 11.

[0051] The rotation of the laser spectrometer 11 can be fan-shaped, circular, or semi-circular, and the laser irradiation direction of the laser spectrometer 11 can be planar irradiation, oblique upward irradiation, or oblique downward irradiation.

[0052] Visible light emitter 63 emits laser light that illuminates visible light beam splitter 62. Visible light beam splitter 62 splits the laser light into two beams that illuminate laser 61 and first reflector 64 respectively. First reflector 64 reflects the laser light onto second reflector 65. Second reflector 65 reflects the laser light through reference sample 66 onto third reflector 67. Third reflector 67 illuminates the laser light through collimating lens 68 onto beam splitter 69. Beam splitter 69 splits the laser light into two beams that illuminate detector 70 and fourth reflector 71 respectively. Fourth reflector 71 reflects the laser light onto laser reflector 12. Laser reflector 12 reflects the received laser light back onto fourth reflector 71 to enhance the laser intensity of the laser emitting device.

[0053] Furthermore, the fourth reflecting mirror 71 reflects the laser back to the beam splitter 69, which reflects the laser onto the laser 61 and the collimating lens 68 respectively. The collimating lens 68 collimates the laser onto the third reflecting mirror 67, which reflects the laser onto the reference sample 66. The reference sample 66 is used to determine the laser light flux. When the reflected laser light flux is at its maximum, the reference sample 66 is rotated to move it away from the laser. Then, the visible light emitter 63 and the visible light splitter 62 are removed, and the laser 61 is turned on. This completes the laser light path path of the laser 61, saving adjustment time.

[0054] In this preferred embodiment, when the laser spectrometer illuminates the laser reflector, if the laser deviates from the reflecting device, the vertical position of the reflecting device is adjusted by the lifting component, the horizontal position is adjusted by the first rotating component, and the vertical angle of the reflecting device is adjusted by the second rotating component. This ensures that the laser from the laser spectrometer accurately illuminates the laser reflector, which then reflects the laser back into the laser spectrometer, thereby enhancing the intensity of the laser within the spectrometer. This eliminates the need for manual adjustment, increases the efficiency of adjustment, and makes the instrument more convenient to use.

[0055] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
