Description

Technical Field

[0001] The utility model relates to the technical field of Raman spectrum analyzers, in particular to an automatic sample loading and unloading mechanism for Raman spectrum analyzers. Background Art

[0002] Raman spectroscopy is a non-destructive analytical technique based on the interaction between light and chemical bonds within materials. It can provide detailed information on the sample's chemical structure, phase and morphology, crystallinity, and molecular interactions. Raman spectroscopy is mainly used in scientific research institutes, physical and chemical laboratories in colleges and universities, and in the medical field to study the determination and confirmation of material composition.

[0003] The existing problem is that during the movement and concentration of the glass slide sample placed on the sample stage of the Raman spectrometer, the sample liquid on the glass slide and the bottom mirror are easily offset by external force, and repeated re-concentration is required;

[0004] The reason for this problem is that when observing a glass slide sample, the current Raman spectrometer will adjust the position of the glass slide sample on the sample stage through a knob. When adjusting the height of the sample stage up and down, it is necessary to simultaneously rotate the eyepiece for focusing, and the distance between the eyepiece and the sample stage is limited. When rotating the eyepiece, the hand is likely to touch the glass slide sample, causing an offset between the sample liquid on the glass slide and the bottom mirror. It is also necessary to repeatedly adjust the position of the glass slide sample for re-focusing, making the detection process more time-consuming. In view of the shortcomings of the existing technology, we propose an automatic sample loading and unloading mechanism for Raman spectrometers to solve the above problems. Utility Model Content

[0008] A clamping member, which is arranged inside the storage platform and is used to clamp and fix the sample;

[0009] A screw rod and a sleeve are arranged inside the storage platform, and the inside of the storage platform is used to move the clamping piece.

[0010] Preferably, a square groove is provided on the top side of the storage table, and the clamping member is slidably connected inside the square groove.

[0013] A movable plate, which is arranged on the side wall of the sleeve, and is used to connect the limit block and the sleeve;

[0014] A clamping plate is arranged on the side wall of the storage table and is used to fix the screw rod.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The embodiment of the present application provides an automatic sample loading and unloading mechanism for a Raman spectrometer, thereby solving the problem that during the movement and focusing of a glass slide sample currently placed on the sample stage of the Raman spectrometer, external forces may cause the sample liquid on the glass slide to deviate from the bottom mirror, and repeated re-focusing is required.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a sample automatic loading and unloading mechanism for a Raman spectrometer.

[0029] According to the attached Figure 1-4 As shown, the automatic sample loading and unloading mechanism for the Raman spectrometer comprises a Raman spectrometer 1 and a storage table 2 arranged on the side wall of the Raman spectrometer 1, and a knob 101 for moving the storage table 2 is arranged on the side wall of the Raman spectrometer 1;

[0030] The specific functions of the Raman spectrometer 1 can be referred to the laser Raman spectrometer of model Finder Vista.

[0031] A fixing assembly 3 is provided inside the storage table 2, and the fixing assembly 3 includes:

[0032] A clamping member 301 is disposed inside the storage platform 2 and is used to clamp and fix the sample;

[0033] The screw rod 4 and the sleeve 401 are arranged inside the storage platform 2 , and the inside of the storage platform 2 is used to move the clamping member 301 .

[0034] A square groove 201 is formed on the top side of the storage platform 2 , and the clamping member 301 is slidably connected inside the square groove 201 .

[0035] The bottom of the clamp 301 is fixedly connected to a limit block 302, and the limit block 302 is slidably connected to the inside of the storage table 2. The limit block 302 is used to limit the clamp 301. The limit block 302 can drive the clamp 301 to move horizontally, thereby avoiding the clamp 301 from moving at any angle.

[0036] The fixing component 3 also includes:

[0037] A movable plate 202, which is arranged on the side wall of the sleeve 401, and the movable plate 202 is used to connect the limit block 302 and the sleeve 401;

[0038] The clamping plate 5 is arranged on the side wall of the storage table 2 , and is used to fix the screw rod 4 .

[0039] The screw 4 is rotatably connected to the inside of the storage table 2, and the sleeve 401 is threadedly connected to the outer peripheral wall of the screw 4. The sleeve 401 and the side wall of the limit block 302 are fixedly connected with a connecting piece 203, and the movable plate 202 is rotatably connected to the inside of the connecting piece 203. By rotating the screw 4, the screw 4 can rotate in situ inside the storage table 2 and can drive the sleeve 401 to move outward. At this time, the moving sleeve 401 will drive the movable plate 202 to rotate, and at the same time, the movable plate 202 will drive the clamping piece 301 to slide the square groove 201 to clamp and fix the sample on the top of the storage table 2.

The pulling force of the spring 502 can restore the card plate 5 to its original position. At this time, the card plate 5 will be connected to the groove 403 on the side wall of the rotating plate 402 to fix the screw rod 4 and prevent the screw rod 4 from rotating at will.

[0042] When the utility model is in use, the sample is first placed on the top of the storage table 2, and then the screw 4 is rotated to drive the sleeve 401 to move outward. At this time, the moving sleeve 401 will drive the movable plate 202 to rotate, and will drive the clamping member 301 to slide into the square groove 201 until the clamping member 301 clamps and fixes the sample on the top of the storage table 2. Finally, the position of the storage table 2 is adjusted up and down by rotating the knob 101, and the sample is observed by focusing through the eyepiece.
