As shown in fig. 1-3, in one embodiment, a spectrometer 40 is provided that includes a sample support module 10, a spectroscopy module 20, and a motion module 30.

The sample bearing module 10 is provided with a sample placing position for placing a sample to be detected, and the sample placing position is provided with a first detection window 111 for allowing detection light to pass through. The detection light passing through the first detection window 111 is irradiated onto the sample to be measured at the sample placement position.

The spectrum module 20 is used for sending detection light and receiving reflection light passing through a sample to be detected, wherein the reflection light belongs to a spectrum signal carrying sample characteristics.

The moving module 30 is configured to drive the spectrum module 20 to move relative to the sample-holding module 10, during which the detecting light emitted by the spectrum module 20 can irradiate the first detecting window 111, and the spectrum module 20 can receive the reflected light passing through the sample to be detected.

The moving module 30 drives the spectrum module 20 to move relative to the sample carrying module 10 during the detection process, so that the spectrum module 20 can sweep a plurality of parts of the sample to be detected at the sample placement position, and the scanning area is increased. In the process, the spectrum module 20 is in a moving state, and the sample bearing module 10 is kept static, so that the potential safety hazard in detection can be effectively reduced.

When the section omics spectrum of the non-mean sample such as emulsion, suspension and the like is obtained, the distribution of sample components is changed if the sample moves, and the detection cannot be normally carried out. By using the movement of the spectroscopy module 20 in this application, the sample support module 10 remains stationary, which effectively avoids this problem.

It should be noted that, in the present application, the area of the first detection window 111 is relatively large, and the area of the first detection window 111 can satisfy that the spectrum module 20 can always correspond to the first detection window 111 in a relatively long period of time during the movement of the spectrum module 20, so as to ensure that the detection light transmitted by the spectrum module 20 always irradiates the first detection window 111 in the period of time, and the spectrum module 20 can always receive the reflected light that passes through the sample to be detected.

The spectrum module 20 is provided with a second detection window 221, the detection light irradiates the first detection window 111 through the second detection window 221, and the reflection light irradiates the spectrum module 20 through the second detection window 221.

The area of the second detection window 221 is smaller than the area of the first detection window 111, and during the movement of the spectroscopy module 20 relative to the sample support module 10, the second detection window 221 is sequentially opposite to different portions of the first detection window 111.

In some embodiments, motion module 30 drives the sliding of spectroscopy module 20 relative to sample support module 10 to increase the scan area during detection.

As shown in fig. 4, in one embodiment, the first detection window 111 is a rectangular window, and the moving module 30 is configured to drive the spectrum module 20 to move relative to the sample-holding module 10 in a length direction of the rectangular window, wherein the spectrum module 20 is sequentially opposite to each part of the rectangular window during the moving process.

In some embodiments, the second detection window 221 is a rectangular window, the length of the long side of the second detection window 221 is less than the length of the long side of the first detection window 111, and the length of the short side of the second detection window 221 is not greater than the length of the short side of the first detection window 111. The length direction of the second detection window 221 is parallel to the length direction of the first detection window 111.

Moreover, the sample vessel matched with the rectangular window is a cuboid, and the probability of breakage of the cuboid sample vessel when falling is relatively low.

Optionally, in some embodiments, the second detection window 221 is a circular window, and the diameter of the second detection window 221 is not greater than the length of the short side of the first detection window 111.

In other embodiments, the motion module 30 drives the spectroscopy module 20 to rotate relative to the sample support module 10 to increase the scan area during the detection process.

For example, in one embodiment, the first detection window 111 is a circular window, and the motion module 30 is used to drive the spectrum module 20 to rotate relative to the sample support module 10, and the rotation axis is collinear with the axis of the first detection window 111, and the spectrum module 20 is sequentially opposite to each part of the circular window during the rotation.

For example, the second detection window 221 is a circular window, the radius of the second detection window 221 is smaller than the radius of the first detection window 111, and the axis of the second detection window 221 is spaced from and parallel to the axis of the first detection window 111.

Further, in certain embodiments, the sliding direction of the spectroscopy module 20 relative to the sample support module 10 is a first direction. The direction indicated by arrow F1 in fig. 1 is the first direction.

In some embodiments, the motion module 30 includes a telescopic driving member, the telescopic direction of the telescopic driving member is parallel to the first direction, the fixing portion of the telescopic driving member is connected to the sample-holding module 10, and the telescopic portion of the telescopic driving member is connected to the spectrum module 20. The flexible driving piece can be the pneumatic cylinder, and the cylinder body of pneumatic cylinder is the fixed part, and the telescopic link of pneumatic cylinder is the pars contractilis.

In other embodiments, as shown in fig. 1 to 3, the moving module 30 includes a motor 31, a body 311 of the motor 31 is fixed in a first direction relative to the sample-holding module 10, a main shaft 312 of the motor 31 is arranged in the first direction, and the spectrum module 20 and the main shaft 312 of the motor 31 are in threaded fit to form a screw nut structure.

Because the sliding guide component 32 is arranged between the body 311 of the motor 31 and the spectrum module 20, when the main shaft 312 of the motor 31 rotates, the spectrum module 20 does not rotate, but slides along the first direction under the action of the sliding guide component 32, so that the spectrum module 20 can sweep through each part of the first detection window 111, and the scanning area is increased.

As shown in fig. 2, the sliding guide assembly 32 includes a guide rail 321 and a first slider 322 slidably engaged with the guide rail 321, and the guide direction of the guide rail 321 is a first direction. The guide rail 321 is fixed relative to the body 311 of the motor 31, and the first slider 322 is connected to the spectrum module 20.

Therefore, when the motor 31 is operated, the spectrum module 20 is slid with respect to the component mount 33 by the slide guide assembly 32. While the body 311 of the motor 31 and the sample-holding module 10 are relatively fixed in a first direction, in other words the component mount 33 is fixed in the first direction with respect to the sample-holding module 10, and the spectrum module 20 slides in the first direction with respect to the sample-holding module 10.

When the spectrum module 20 moves to a position where the distance between the spectrum module 20 and any of the supporting frames 341 is smaller than the allowable limit value, the motor 31 may stop operating according to the feedback of the distance sensor 35, so as to prevent the spectrum module 20 from colliding with the supporting frame 341 and causing damage to important parts in the spectrometer 40.

More specifically, as shown in fig. 1 and 2, two distance sensors 35 are respectively connected to two supporting frames 341, two stoppers 23 are disposed on the spectrum module 20, and the stoppers 23 correspond to the distance sensors 35 one by one.
