Description

Technical Field

[0001] The utility model relates to the field of supporting instruments for Raman instruments, in particular to an automatic switching accessory for multiple detection forms. Background Art

[0002] Portable Raman spectrometers can quickly measure the composition of liquids, solids and powders. At present, in the preparation stage of the test, liquid samples will be placed in liquid vials or cuvettes for testing, solid samples can be directly placed at the light focus point for testing, and powder samples are generally placed in liquid vials, cuvettes or thin plastic bags for testing. In addition, for objects with weak signals, liquid reagents can be added or solidified on enhanced chips for testing. Portable Raman spectrometers have one or two fixed detection ports, and one detection port is usually equipped with a fixed position or container corresponding to the sample. Then, when there are multiple types of sample detection requirements, the above detection positions are obviously not enough. Therefore, it is necessary to propose an accessory that automatically switches the detection position to match the detection requirements for different sample types. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0021] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] In this embodiment, multiple detection modes are proposed to automatically switch accessories. Figure 1-Figure 3 The multi-detection form automatic switching accessory includes a main body 1 and an incident light focusing and returning light part 2 located in the main body 1.

[0024] like Figure 1 As shown, a support plate 4 is provided in front of the incident light focusing and returning light portion 2, and a stepper motor 3 is provided for driving the support plate 4 to rotate axially. The transmission part of the stepper motor 3 is an axis 7, and the axis 7 is vertical and combined with the axis center of the support plate 4 at the bottom of the support plate 4. In this way, the support plate 4 can be driven by the stepper motor 3 in front of the incident light focusing and returning light portion 2 and then rotate axially.

[0025] Different from the existing structure, in this embodiment, the top of the support plate 4 has a solid and plastic packaging placement part 9 located at the focal position of the incident light, a liquid vial placement part 10, an enhanced chip placement part 11 and a cuvette placement part 12.

[0026] Further, the solid and plastic packaging placement portion 9, the liquid vial placement portion 10, the enhanced chip placement portion 11 and the cuvette placement portion 12 are at an angle of 90° to each other. Figure 2 and Figure 3 As shown, the liquid phase vial placement portion 10, the enhancement chip placement portion 11 and the cuvette placement portion 12 have openings 13 for incident light to enter.

[0027] To further explain, when the stepper motor 3 drives the support plate 4 to rotate axially, only one of the solid and plastic packaging placement part 9, the liquid vial placement part 10, the enhanced chip placement part 11 and the cuvette placement part 12 will be located at the incident light focusing position.

[0028] In this embodiment, the stepper motor 3 has a reset function. Specifically, Figure 1 The photoelectric switch 5 shown is combined with the main unit 1, and the photoelectric switch 5 is located directly below the incident light focusing return light portion 2, and there is also a pallet extension portion 6 located on the pallet 4 and photoelectrically coordinated with the photoelectric switch 5, wherein the pallet extension portion 6 is the zero point of the pallet 4, and the pallet extension portion 6 is opposite to the solid and plastic packaging placement portion 9.

[0029] To further explain, when the photoelectric switch 5 detects the support plate extension portion 6 , the solid and plastic packaging placement portion 9 is located at the incident light focusing position, which is also the initial position of the stepping motor 3 .

[0030] To further explain, after the personnel select the position through the upper computer software, the stepper motor 3 first detects the initial state by detecting the photoelectric signal. When the position is reset to the initial detection, it automatically rotates the corresponding angle to adjust the detection form according to the type of container selected by the software (90° for liquid phase vial, 180° for enhancement chip, 270° for cuvette). It should be noted that each time it rotates to the specified position, it needs to be reset and then rotated again after resetting.

[0031] The contents that need to be explained in this embodiment include that the stepper motor 3 is equipped with a cable 8 connected to a power source and a controller.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
