The change or adjustment of the relative relationship, without substantial change of technical content, is also regarded as the scope of the implementation of the utility model.

[0031] For example Figures 1-3As shown, the utility model provides a kind of sample detection plate suitable for raman spectrum detection device motion platform, including sample detection plate assembly 3.Sample detection plate assembly 3 is set in the motion platform assembly 2 in raman spectrum detection equipment 1.Raman spectrum detection equipment 1 is provided with movable laser emission and receiving part, and raman spectrum detection equipment 1 emits laser and receives reflected light to sample by laser emission and receiving part, and can be used to carry out raman spectrum detection to sample.Motion platform assembly 2 is set in the inside of raman spectrum detection equipment 1, for driving to be detected sample and laser emission and receiving part motion, realize rapid detection.Sample detection plate assembly 3 is set in motion platform assembly 2, and several regions for limiting sample are equidistantly provided on sample detection plate assembly 3, so that the position of sample is consistent with detection point position of raman spectrum detection equipment 1, to ensure that laser emission and receiving part can be collinear with sample on sample detection plate assembly 3 after motion platform assembly 2 drives laser emission and receiving part and sample detection plate assembly 3 each time.

[0032] Among them, the utility model sample detection plate assembly 3 includes support base 301, and the upper portion of support base 301 is provided with sample support frame 302, and a plurality of sample holes 303 are equidistantly formed on sample support frame 302, and anti-skid limiting assembly is symmetrically arranged on the side of support base 301 with the axis of support base 301, for limiting support base 301 on motion platform assembly 2, to avoid that support base 301 deviates under the action of inertia when motion platform assembly 2 moves.

[0033] Through the above technical scheme, support base 301 and sample support frame 302 are matched to be used to improve height, and sample hole 303 arranged is used to limit sample, so that sample can be placed in sample hole 303 or support and limit test tube through sample hole 303.The clearance of each sample hole 303 is provided with corresponding coordinate value in the data logic of raman spectrum detection equipment 1 and motion platform assembly 2.After raman spectrum detection equipment 1 completes detection each time, coordinate information is marked after sample information, to facilitate the form of production detection and clear raman spectrum of each sample, to avoid data confusion.

[0034] As shown in Figure 3 And Figure 5 As shown in some embodiments, the utility model sample hole 303 is bottom-sealed hole or through hole.When sample hole 303 is sealed hole, then the sample to be detected can be directly dropped in sample hole 303 for detection, to improve the convenience of detection.And sample hole 303 is set as through hole, so that the longitudinal depth of hole can be increased, the longer test tube can be inserted into sample hole 303, the time and steps of sample transfer can be reduced, and the convenience and flexibility of detection are improved.

[0035] As shown in Figure 2As shown in the drawings, in some embodiments, the utility model motion platform assembly 2 includes a horizontal motion platform 201 and a longitudinal motion platform 202. Among them, the horizontal motion platform 201 is used to drive the laser emission and receiving part to move horizontally, so as to be able to horizontally sweep all the samples in the sample hole 303. And the longitudinal motion platform 202 is used to drive the sample detection plate assembly 3 to move longitudinally, which is used in cooperation with the horizontal motion platform 201. When the laser emission and receiving part detects a row of samples, the longitudinal motion platform 202 drives the sample detection plate assembly 3 to move longitudinally by a distance, so as to facilitate the laser emission and receiving part to detect the next row of samples. The horizontal motion platform 201 and the longitudinal motion platform 202 can generate a cross point of the sample hole 303 position during the movement process, and the point of the cross point is the point of the sample hole 303 arranged on the sample detection plate assembly 3.

[0036] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in some embodiments, the utility model longitudinal motion platform 202 is provided with a sample support frame 203, which is used to increase the support area of the sample detection plate assembly 3, improve the stability of the sample detection plate assembly 3, and reduce the possibility of displacement of the sample detection plate assembly 3 during movement. The sample support frame 203 can be driven by the longitudinal motion platform 202, and the support base 301 is placed on the top of the sample support frame 203.

[0037] As shown in the drawings, Figure 2 and Figure 6 As shown in the drawings, in some embodiments, the utility model sample anti-skid limiting assembly includes an elastic edge strip 304, which is arc-shaped, and a gap is arranged between the inner wall and the outer surface of the support base 301. At the same time, the top of the sample support frame 203 is provided with a limiting groove 204 matched with the bottom section of the support base 301. When the support base 301 is placed on the motion platform assembly 2, the limiting groove 204 is used in cooperation with the elastic edge strip 304 to position the support base 301.

[0038] As shown in the drawings, Figure 2 and Figure 4 As shown in the drawings, in some embodiments, the utility model elastic edge strip 304 has elasticity. After the sample detection plate assembly 3 is placed in the limiting groove 204, the outer surface of the elastic edge strip 304 and the inner wall of the limiting groove 204 are in contact due to the elasticity of the elastic edge strip 304, so as to further improve the stability of the sample detection plate assembly 3 and avoid the slight shaking of the sample detection plate assembly 3 in the limiting groove 204.

[0039] As shown in the drawings, Figure 4As shown, in some embodiments, the outer surface of the elastic strip 304 extends beyond the outer surface of the sample support frame 302. When the support base 301 is placed in the limiting groove 204, the protruding elastic strip 304 can better abut against the inner wall of the limiting groove 204, increasing the contact area and thus improving the stability of the limiting.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the support base 301 of this utility model has a sheet-like frame structure, and the projected area of ​​the support base 301 is larger than the projected area of ​​the sample support frame 302. The sheet-like frame structure of the support base 301 allows the bottom of the sample support frame 302 to be suspended, thereby increasing the depth of the test tube placement and improving the stability of the test tube placement.

[0041] The surface of the support base 301 on which the elastic strip 304 is mounted is through the interior of the support base 301. This effectively increases the deformation space of the elastic strip 304 and improves the compatibility between the support base 301 and the motion platform assembly 2.

[0042] like Figure 1 As shown, in some embodiments, the outer surface of the Raman spectroscopy detection device 1 of this invention is provided with a shell. The shell is used to protect all equipment and to keep the sample in a relatively closed environment during sample detection, reducing environmental interference with the sample detection results. The shell has a compartment opening, and both the sample support frame 203 and the sample cavity 303 can be moved to the outside of the shell compartment opening to facilitate the placement and removal of the sample detection plate assembly 3. A gap is left between the top of the sample cavity 303 and the top of the shell compartment opening of the Raman spectroscopy detection device 1. This gap allows test tubes to enter and exit the Raman spectroscopy detection device 1 when inserted into the sample cavity 303, preventing the compartment opening from being too low and obstructing the entry and exit of the test tubes.

[0043] The specific usage process of this utility model is as follows:

[0044] The longitudinal motion platform 202 is controlled by a control switch to drive the sample support frame 203 to move to the outside of the outer casing of the Raman spectroscopy detection device 1;

[0045] The sample is dripped into the sample cavity 303 or the test tube carrying the sample is inserted into the sample cavity 303. Then the sample detection plate assembly 3 is placed in the limiting groove 204 at the top of the sample support frame 203 at the angle of the limiting groove 204.

[0046] Gently press down on the sample detection plate assembly 3 so that the elastic strip 304 on the side of the support base 301 is forced into the interior of the limiting groove 204, and the elasticity of the elastic strip 304 completely fixes the sample detection plate assembly 3 in the limiting groove 204.

[0047] By controlling the switch to control the longitudinal motion platform 202 to drive the sample support frame 203 to move to the inside of the Raman spectrum detection device 1 shell, the sample is subjected to Raman spectrum detection.

[0048] In summary, the sample detection plate matched with the Raman spectrum detection device motion platform, by equidistantly arranging a plurality of sample limiting areas on the sample detection plate assembly 3, and the sample limiting areas are matched with the interval of the motion platform assembly 2, therefore, when the sample detection is performed, the motion platform assembly 2 can drive the sample to accurately fall into the Raman spectrum detection device 1 detection part below for detection, which improves the equipment matching degree and improves the detection convenience.

[0049] Meanwhile, the utility model discloses the top of sample support frame 203 sets up the limit slot 204 to support the base 301 to limit, ensure that the position of support base 301 places accurate, and set up the elastic edge strip 304 on the side of support base 301, through the elasticity of elastic edge strip 304 with support base 301 fixed in the inside of limit slot 204, avoid support base 301 when the movement of sample support frame 203 and shift, which improves the effect of limiting accuracy.

[0050] Therefore, the utility model effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.

[0051] The above embodiments only exemplarily illustrate the principles and effects of the utility model, and are not used to limit the utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
