Description

Technical Field

[0001] This utility model relates to the field of infrared spectrometer technology, specifically to an automatic calibration infrared spectrometer adjustment mechanism. Background Technology

[0002] Infrared spectrometers, as precision instruments that utilize the absorption characteristics of substances to infrared light for component analysis and structural identification, are widely used in many fields such as chemistry, materials science, pharmaceutical research and development, environmental monitoring, and food testing. Their core principle is to determine the chemical composition and molecular structure of a substance by measuring the absorption spectrum of a sample in the infrared band and based on the characteristic absorption peaks of the "molecular fingerprint region." They offer significant advantages such as fast analysis speed, simple sample pretreatment (or even no pretreatment required), and non-destructive operation.

[0003] The existing technology has the following problems: In addition, if the spectrometer is placed on an uneven operating table, it will be difficult to keep it level, which will easily affect the stability of the spectrometer, lead to measurement data deviation, and increase the difficulty of calibration. At the same time, the object to be tested should be accurately aligned with the position below the spectrometer detection head before the object is placed. However, the probe may shift after contacting the object, which is not conducive to the detection of the object and will also reduce the detection effect.

[0004] Therefore, this invention provides an automatic calibration infrared spectrometer adjustment mechanism to solve the above problems. Utility Model Content

[0005] This invention provides an automatic calibration adjustment mechanism for an infrared spectrometer, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including an infrared spectrometer and an adjustment structure mounted below the infrared spectrometer, as well as a clamping structure mounted inside the infrared spectrometer;

[0007] The adjustment structure includes a disk fixedly connected to the bottom of the infrared spectrometer and four first servo motors arranged in a circumferential array inside the disk, as well as a movable plate rotatably connected to the inner wall of the disk. The output end of each of the first servo motors is fixedly connected to a threaded rod, and a ring is threadedly connected to the surface of the threaded rod. Two fixed posts are symmetrically distributed on both sides of the surface of the ring, and sliders are rotatably connected to the surface of the fixed posts. The sliders are slidably connected to the inner wall of the movable plate, and an attitude sensor is fixedly installed on one side of the top surface of the disk.

[0008] As a preferred technical solution of this application, the surface of the disc is provided with four grooves for the movable plate to move, and the surface of the movable plate is provided with rectangular grooves for the ring and the threaded rod to move.

[0009] As a preferred technical solution of this application, the inner wall of the groove is provided with a circular hole for mounting the first servo motor, and both sides of the inner wall of the rectangular groove are provided with sliding grooves for sliding of the slider.

[0010] As a preferred technical solution of this application, an attitude sensor is fixedly installed on one side of the top surface of the disk, and the surface of the disk is provided with rounded corners.

[0011] As a preferred technical solution of this application, the clamping structure includes a second servo motor disposed on one side inside the infrared spectrometer and a T-shaped plate assembled on the other side inside the infrared spectrometer, and a bidirectional threaded rod fixedly connected to the output end of the second servo motor. The bidirectional threaded rod passes through the T-shaped plate, and the bidirectional threaded rod is threadedly connected to two clamping plates that are symmetrically distributed. Several springs are linearly arranged on the opposite side of the two clamping plates, and a buffer rod is sleeved inside the spring.

[0012] As a preferred technical solution of this application, the surface of the clamping plate is provided with a groove that is slidably connected to the surface of the T-shaped plate, and anti-detachment blocks are fixedly connected to both ends of the T-shaped plate.

[0013] As a preferred technical solution of this application, a washer is fixedly connected to the end of the spring away from the clamping plate, and an anti-slip pad is provided on one side of the washer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By adjusting the structural settings, the four sets of first servo motors drive the circular ring to move linearly via threaded rods when the attitude sensor detects that the disk is not on a horizontal plane. Through the linkage between the fixed column and the slider, the movable plate moves around the axis of rotation connected to the cylinder, thereby realizing multi-angle micro-adjustment. The horizontal position of the disk can be quickly adjusted to ensure that the infrared spectrometer is in a horizontal state. Compared with the traditional manual calibration mode, the adjustment speed of this device is faster, and it also improves the stability of the infrared spectrometer and increases the calibration speed of the infrared spectrometer.

[0016] By employing a bidirectional threaded rod symmetrical transmission design in the clamping structure, and guided by a T-shaped plate to achieve synchronous relative movement of the clamping plates, the elastic clamping unit, composed of a linear array of springs and buffer rods, ensures the concentricity and stability of sample clamping, avoiding sample breakage or deformation caused by rigid clamping. The anti-slip pads on the gaskets further enhance friction, preventing sample slippage during the detection process and significantly reducing spectral baseline drift caused by sample positioning errors, thereby improving the detection effect.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-5 The automatic calibration infrared spectrometer adjustment mechanism shown includes an infrared spectrometer 1, an adjustment structure 2 mounted below the infrared spectrometer 1, and a clamping structure 3 mounted inside the infrared spectrometer 1.

[0025] The adjustment structure 2 includes a disk 201 fixedly connected to the bottom of the infrared spectrometer 1 and four first servo motors 202 arranged in a circumferential array inside the disk 201, as well as a movable plate 203 rotatably connected to the inner wall of the disk 201. The output end of the first servo motor 202 is fixedly connected to a threaded rod 204. A ring 205 is threadedly connected to the surface of the threaded rod 204. Two fixed posts 206 are symmetrically distributed on both sides of the surface of the ring 205. A slider 207 is rotatably connected to the surface of the fixed posts 206. The slider 207 is slidably connected to the inner wall of the movable plate 203. An attitude sensor 208 is fixedly installed on one side of the top surface of the disk 201.

[0026] Using the above scheme, when the device is placed on a table, the attitude sensor 208 will convert the attitude information of the disk 201 and send it to the first servo motor 202. If the disk 201 is not on a horizontal plane, it will drive the corresponding first servo motor 202 to rotate, which will drive the threaded rod 204 to rotate, and then drive the ring 205 to move. The fixed posts 206 on both sides of the ring 205 will drive the slider 207 to slide in the sliding groove on the inner wall of the rectangular groove of the movable plate 203, so that the movable plate 203 can move around the axis of rotational connection with the cylinder, thereby realizing multi-angle micro-adjustment and quickly adjusting the horizontal position of the disk 201.

[0027] The surface of the disc 201 has four grooves for the movable plate 203 to move. The surface of the movable plate 203 has rectangular slots for the ring 205 and the threaded rod 204 to move. The inner wall of the groove has a circular hole for the first servo motor 202 to be installed. Both sides of the inner wall of the rectangular slot have sliding grooves for the slider 207 to slide. An attitude sensor 208 is fixedly installed on one side of the top surface of the disc 201. The surface of the disc 201 has rounded corners. The clamping structure 3 includes a second servo motor 301 located on one side inside the infrared spectrometer 1 and a T-shaped plate 302 assembled on the other side inside the infrared spectrometer 1, as well as a fixed... A bidirectional threaded rod 303 is connected to the output end of the second servo motor 301. The bidirectional threaded rod 303 passes through the T-shaped plate 302 and is threaded to two symmetrically distributed clamping plates 304. Several springs 305 are linearly arranged on the opposite side of the two clamping plates 304. A buffer rod is sleeved inside the spring 305. The surface of the clamping plate 304 is provided with a slot that is slidably connected to the surface of the T-shaped plate 302. Anti-detachment blocks 306 are fixedly connected to both ends of the T-shaped plate 302. A washer 307 is fixedly connected to the end of the spring 305 away from the clamping plate 304. An anti-slip pad is provided on one side of the washer 307.

[0028] Using the above scheme, the second servo motor 301 drives the bidirectional threaded rod 303 to rotate, and the clamping plate 304 moves synchronously relative to each other through the T-shaped plate guide. Together with the linear array of springs 305 and the buffer rod, they form an elastic clamping unit to ensure the concentricity and stability of the sample clamping. The springs 305 can also adapt to samples of different thicknesses and materials, such as thin sheets and powder tablets, through deformation, avoiding sample breakage or deformation caused by rigid clamping. The anti-slip pad on the gasket 307 further enhances the friction and prevents the sample from slipping during the detection process.

[0029] The first servo motor 202, the attitude sensor 208, and the second servo motor 301 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated further in this article.

[0030] The working principle of the automatic calibration infrared spectrometer adjustment mechanism based on the embodiment is as follows: after the device is placed on the table, the attitude sensor 208 monitors the attitude of the disk 201 in real time. If the disk 201 is not horizontal, it transmits the information to the corresponding first servo motor 202, drives the threaded rod 204 to rotate, drives the ring 205 to move, and the fixed column 206 drives the slider 207 to slide in the sliding groove of the movable plate 203, so that the movable plate 203 is adjusted around the rotation axis, and the disk 201 is quickly calibrated to be horizontal.

[0031] Subsequently, the second servo motor 301 is started, driving the bidirectional threaded rod 303 to rotate. Under the guidance of the T-shaped plate, the two clamping plates 304 move synchronously relative to each other along the groove, placing the sample between the two pads 307. The clamping plates 304 continue to move, and the spring 305 and the buffer rod are deformed under pressure, adapting to the sample size. The sample is firmly clamped by elastic force, and the anti-slip pad enhances friction to prevent slippage. Then, the infrared spectrometer 1 can be started for detection.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
