Description

Technical Field

[0001] This utility model relates to the technical field of supporting equipment for fluorescence spectrometers, specifically an auxiliary carrier for fluorescence spectrometers. Background Technology

[0002] In fluorescence spectroscopy analysis experiments, samples need to be precisely transferred to the spectrometer's detection area. Traditional auxiliary carriers have the following drawbacks: first, they have poor compatibility with sample containers, making it difficult to simultaneously accommodate glassware (such as cuvettes) and test tubes; second, the sample transfer and lifting processes are prone to shaking and shifting, affecting the alignment accuracy of the detection optical path; and third, they lack a stable structural design, and components are prone to wear after long-term use, leading to carrier malfunctions and inaccurate positioning. Existing carriers cannot meet the requirements of multi-sample, high-precision detection and urgently need optimization and upgrading. Utility Model Content

[0003] (a) Technical problems to be solved.

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary carrier for a fluorescence spectrometer, solving the problems mentioned in the background section.

[0005] (ii) Technical solution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary carrier for a fluorescence spectrometer, comprising an electric component, a moving frame, and a carrier assembly.

[0007] The core of the electric component is the electric guide rail, which has waist-shaped holes at both ends of the bottom. Each group contains two holes and is symmetrically distributed front and back. It is used to fix the carrier on the spectrometer detection platform. One end of the electric guide rail is equipped with a control interface, which can be connected to an external control system to receive commands and drive the guide rail to move, so as to realize the horizontal movement of the carrier.

[0008] The mobile frame includes an electric slider that is slidably mounted on the outside of an electric guide rail. A connecting frame is fixedly connected to each of the front and rear ends of the electric slider. Slide rods are fixedly connected to the top of the connecting frame on both sides. The tops of the two slide rods on the same side are connected to a stop block to limit the sliding stroke of the vehicle assembly. A drive motor is fixedly installed on one side of the electric slider. A screw is fixedly connected to the drive end of the drive motor to provide power for the lifting and lowering of the vehicle assembly.

[0009] The carrier assembly consists of a loading frame that is slidably mounted on the outside of four slide bars. Two glassware mounting holes are symmetrically opened between the upper and lower side walls of one end of the loading frame. A first rubber protective ring is fixed to the inner side wall of the hole to buffer the collision between the glassware and the hole wall. Nine test tube mounting holes are opened in a rectangular array between the upper and lower side walls of the other end of the loading frame. A second rubber protective ring is fixed to the inner side wall of the hole to prevent the test tubes from being worn. Threaded holes for screw thread connection are opened between the upper and lower walls of the loading frame and are located between the two glassware mounting holes. When the drive motor is running, the screw drives the loading frame to rise and fall stably along the slide bars. A bracket is fixed at the bottom of the loading frame corresponding to each row of test tube mounting holes. A buffer rubber pad is fixed to the inner bottom wall of the bracket to further support the test tubes and reduce shaking. Sliding grooves are opened at the four corners of the loading frame to slide and cooperate with the slide bars to ensure the stability of the lifting process.

[0010] As a further improvement of this utility model, the waist-shaped holes at both ends of the electric guide rail facilitate adjustment of the fixing position according to installation requirements, thereby improving the compatibility between the carrier and the spectrometer.

[0011] As a further improvement of this utility model, the stop is made of hard alloy material, which has high strength, good wear resistance, and is not easily deformed after long-term use, thus stably limiting the travel of the vehicle components.

[0012] As a further improvement of this utility model: the first rubber protective ring and the second rubber protective ring are made of chemically resistant silicone material, which can be used with acid and alkali sample containers and extend the service life of the protective ring. The top of the loading rack and the front and rear ends of each glass container assembly hole are fixedly connected with a card seat, which can limit the placement of the glass container at the edge.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, glassware and test tube samples can be simultaneously supported by the glassware assembly hole and the test tube assembly hole, adapting to different experimental scenarios. The rubber protective ring further protects the container and avoids damage from bumps.

[0015] 2. In this utility model, the sliding fit between the slide rod and the slide groove, and the supporting design of the bracket and the buffer pad, make it less likely for the sample to shake or shift during horizontal transfer and lifting, thus ensuring the alignment accuracy of the detection optical path.

[0016] 3. In this utility model, the mounting components are fixed and installed through the waist-shaped hole, which facilitates installation and debugging. The layout of components such as the stop and screw is reasonable, which reduces wear during operation. The drive motor works with the screw transmission to improve the lifting control accuracy and ensures stable operation even after long-term use. Attached Figure Description

[0025] Please see Figures 1-4 In this embodiment of the present invention, an auxiliary carrier for a fluorescence spectrometer includes an electric component 1, a moving frame 2, and a carrier component 3.

[0026] The core of the electric component 1 is the electric guide rail 11, which has waist-shaped holes 12 at the bottom of both ends. Each group contains two holes and they are symmetrically distributed front and back. They are used to fix the carrier on the spectrometer detection platform. One end of the electric guide rail 11 is equipped with a control interface 13, which can be connected to an external control system to receive commands and drive the guide rail to move, so as to realize the horizontal movement of the carrier.

[0027] The movable frame 2 includes an electric slider 21 that is slidably mounted on the outside of the electric guide rail 11. A connecting frame 22 is fixedly connected to each of the front and rear ends of the electric slider 21. Slide rods 23 are fixedly connected to the top of the connecting frame 22 on both sides. The tops of the two slide rods 23 on the same side are connected to a stop block 24 to limit the sliding stroke of the vehicle assembly 3. A drive motor 25 is fixedly installed on one side of the electric slider 21. A screw 26 is fixedly connected to the drive end of the drive motor 25 to provide power for the lifting and lowering of the vehicle assembly 3.

[0028] The carrier assembly 3 consists of a loading frame 31 that is slidably mounted on the outside of four slide rods 23. Two glassware mounting holes 33 are symmetrically opened between the upper and lower side walls of one end of the loading frame 31. A first rubber protective ring 37 is fixed to the inner side wall of the hole to buffer the collision between the glassware and the hole wall. Nine test tube mounting holes 35 are opened in a rectangular array between the upper and lower side walls of the other end of the loading frame 31. A second rubber protective ring 38 is fixed to the inner side wall of the hole to prevent the test tubes from being worn. Threaded holes 34 for threaded connection of screws 26 are opened between the upper and lower walls of the loading frame 31 and are located between the two glassware mounting holes 33. When the drive motor 25 is running, the screws 26 drive the loading frame 31 to rise and fall stably along the slide rods 23. A bracket 39 is fixed at the bottom of the loading frame 31 corresponding to each row of test tube mounting holes 35. A buffer rubber pad 310 is fixed to the inner bottom wall of the bracket 39 to further support the test tubes and reduce shaking. Sliding grooves 32 are opened at the four corners of the loading frame 31 to slide and cooperate with the slide rods 23 to ensure the stability of the lifting process.

[0029] The waist-shaped holes 12 at both ends of the electric guide rail 11 facilitate adjustment of the fixing position according to installation requirements, thereby improving the compatibility between the carrier and the spectrometer.

[0030] The stop block 24 is made of hard alloy material, which has high strength and good wear resistance. It is not easily deformed after long-term use and stably limits the stroke of vehicle component 3.

[0031] The first rubber protective ring 37 and the second rubber protective ring 38 are made of chemically resistant silicone material, which can be used with acid and alkali sample containers and extend the service life of the protective ring. The top of the loading rack 31 and the front and rear ends of the mounting hole 33 of each glassware are fixedly connected to the bracket 36, which can limit the placement of the glassware at the edge.

[0032] The working principle of this utility model is as follows: Glassware, such as cuvettes, is placed into the glassware assembly hole 33, and test tube samples are placed into the test tube assembly hole 35. The rubber protective ring and the bracket 39 together fix the sample to prevent displacement. The external control system sends commands through the control interface 13, and the electric guide rail 11 drives the electric slider 21 to slide, moving the carrier assembly 3 to the spectrometer detection area. The stop block 24 ensures accurate transfer. The drive motor 25 is started, and the screw 26 rotates, causing the loading frame 31 to rise and fall along the slide bar 23, adjusting the height of the sample and the spectrometer detection optical path to match. After the spectrometer completes the detection preparation, the drive motor 25 reverses and the electric guide rail 11 runs in the opposite direction, and the carrier returns to its initial position, waiting for the next operation. That is, the overall auxiliary carrier relies on the electric component 1 to realize the horizontal movement of the carrier, the moving frame 2 to construct the lifting and guiding structure, the carrier component 3 to be compatible with multiple types of sample containers, and the horizontal displacement is precisely controlled by the electric guide rail 11. The drive motor 25, screw 26 and slide bar 23 work together to achieve stable lifting and lowering. The rubber protective ring and bracket 39 ensure sample stability, and finally achieve the auxiliary task of multi-sample, high-precision spectroscopic detection.

[0033] 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.
