[0002] The laser confocal Raman spectrometer is a high-performance micro-Raman spectrometer designed for scientific research, industrial analysis, and education. This instrument possesses several advanced technical features, ensuring superior performance in sensitivity, resolution, stability, and ease of use. The laser confocal Raman spectrometer operates by using a laser source to generate a laser of a specific wavelength to excite the sample, producing Raman scattering. After passing through a series of optical components, the light reaches the detector, where it is processed by a computer to obtain the Raman spectrum.

[0003] In existing technology, when placing samples, the sample must first be placed on a glass slide in a cuvette, and then the glass slide containing the sample must be manually transferred to the sample stage of the microscope equipment in a laser confocal Raman spectrometer. When the sample is in powder or liquid form, the glass slide may tilt due to operator carelessness during the transfer process, causing the powder or liquid sample to spill. Furthermore, fixing the glass slide to the sample stage first and then placing the sample can easily contaminate the sample stage.

[0004] To address this issue, we propose a sample transfer and positioning device suitable for Raman testing, which solves the problem of sample spillage during placement in existing technologies. Utility Model Content

[0032] like Figure 1-4As shown, this utility model provides a sample transfer and positioning device suitable for Raman testing, including: a gripping component 1, a driving component 2, and a feeding component 3;

[0033] The loading assembly 3 includes an operating table 31, and the upper end of the operating table 31 is provided with a placement slot 310 for placing external glass slides and adding samples.

[0034] The drive assembly 2 includes a slide rail 20. A motor 22 is connected to the inner wall of one end of the slide rail 20. A screw 23 is connected to the output end of the motor 22. The other end of the screw 23 is rotatably connected to the inner wall of the slide rail 20. The slide rail 20 supports the motor 22 and the screw 23. A slider 21 is connected inside the slide rail 20 and is slidably connected to the slide rail 20. The screw 23 passes through the slider 21 and an electric push rod 12 is connected to its lower end. The slider 21 is threadedly connected to the screw 23. The lower end of the electric push rod 12 is connected to a gripping assembly 1, which is used to grip an external glass slide located in the placement slot 310. In use, activating the electric push rod 12 causes it to lower the gripping component 1 to grasp the slide carrying the sample. After grasping, the slide rises back to its original position. Activating the motor 22 then rotates the screw 23, which in turn moves the slider 21 horizontally. The slider 21, through the electric push rod 12 and the gripping component 1, smoothly moves the slide carrying the sample above the stage of the external microscope. Activating the electric push rod 12 again lowers the gripping component 1, placing the slide smoothly onto the microscope stage. This device ensures the smooth movement and placement of the sample on the microscope stage, preventing the slide from tilting and spilling when held by the operator.

[0035] In one embodiment, the gripping assembly 1 includes a top plate 10 connected to the telescopic end of the electric push rod 12. Several electric suction cups 11 are connected to both sides of the lower end of the top plate 10 for adsorbing and gripping external glass slides. The top plate 10 supports the electric suction cups 11, which are evenly distributed on both sides of the top plate 10, allowing for suction and fixation of the glass slide from both sides, thus improving gripping stability.

[0036] In one embodiment, the top plate 10 has a square structure and its size is similar to that of the external glass slide, which facilitates determining the installation position of the electric suction cup 11 based on the position of the top plate 10, thereby achieving fixed-point adsorption and fixation of the glass slide. There are at least two electric suction cups 11 on each side, which can keep the glass slide in a horizontal state and prevent the glass slide from tilting.

[0037] In one embodiment, the electric push rod 12 is connected to the top plate 10 via a first connecting member 13. The first connecting member 13 includes two mutually sliding sleeves 130, with a spring 131 connecting the two sleeves 130. In use, the electric push rod 12 drives the electric suction cup 11 to descend via the top plate 10. After the electric suction cup 11 contacts the glass slide, the electric push rod 12 continues to descend a certain distance to ensure that the electric suction cup 11 is in close contact with the glass slide for adsorption. After the electric suction cup 11 is fully in close contact with the glass slide, the electric suction cup 11 and the top plate 10 remain stationary relative to the glass slide. The electric push rod 12 continues to descend a certain distance, at which point the two sleeves 130 retract relative to each other and compress the spring 131, relieving the squeezing force caused by the descent of the electric push rod 12 and preventing the glass slide or the electric suction cup 11 from being squeezed and damaged.

[0038] In one embodiment, one end of the slide rail 20 is connected to the side wall of the external microscope, and the operating stage 31 is located below the other end of the slide rail 20, with the two connected by a bracket 30. The bracket 30 has an L-shaped structure and is used to support the operating stage 31, allowing for loading operations on the operating stage 31. The slide rail 20 allows the sample-laden slide to be moved horizontally onto the microscope stage, reducing the instability of manual operation. The bracket 30 has an L-shaped structure and is detachably connected to the operating stage 31, facilitating the removal of the operating stage 31 for cleaning.

[0039] In one embodiment, the slider 21 has an L-shaped structure, and the electric push rod 12 is located at the lower right end of the slider 21. This facilitates the slider 21 to move the gripping assembly 1 to the upper center position of the microscope sample stage via the electric push rod 12 for placing the glass slide.

[0040] In one embodiment, the upper end of the operating platform 31 is connected to the guide frame 32, which covers the edge of the slide inside the placement slot 310, guiding the operator to place the sample in the center of the slide and preventing sample spillage. The upper end of the guide frame 32 is connected to the cover plate 33, which covers the guide frame 32 to prevent dust from settling on the sample when not in use, thus preventing contamination and affecting Raman detection. In use, the cover plate 33 is first opened, the slide is inserted into the placement slot 310 of the operating platform 31, and the sample is placed in the center of the slide using the guide frame 32. Powdered samples can also be pressed into a flat surface using a tool. Then, the guide frame 32 is opened to expose the slide, facilitating the smooth transfer of the slide by the drive assembly 2.

[0041] In one embodiment, the front end of the placement slot 310 extends through the operating table 31, and the opening at the front end of the placement slot 310 has a downwardly sloping arc. This allows the operator to easily insert the glass slide into the placement slot 310 via the sloping arc at the opening, improving the flexibility of use.

[0042] In one embodiment, the inner sidewall of the guide frame 32 is inclined and faces upward, facilitating the guidance of the sample to fall into the center of the glass slide. The cover plate 33 has a square structure and is similar in size to the guide frame 32, allowing the cover plate 33 to cover the upper part of the guide frame 32 and prevent dust contamination.

[0043] In one embodiment, magnets are provided at the right ends of the operating table 31, guide frame 32, and cover plate 33. The operating table 31 and cover plate 33 are rotatably connected to the guide frame 32. By providing magnets that can attract each other on opposite sides of the connection ends of the three, the opening and closing operation of the three is facilitated. Outwardly extending protrusions 34 are provided on the outer walls of the operating table 31, guide frame 32, and cover plate 33. By providing protrusions 34, it is easy to manually separate the operating table 31 and guide frame 32, or manually separate the guide frame 32 and cover plate 33.

[0044] The specific usage process of this utility model is as follows: Place the glass slide on the loading assembly 3, then place the sample on the glass slide. The electric push rod 12 descends, driving the top plate 10 and the electric suction cup 11 to descend above the glass slide, so that the electric suction cup 11 adheres tightly to the glass slide and adsorbs it. The electric push rod 12 moves in the opposite direction to drive the glass slide to rise. The motor 22 is started, and the motor 22 drives the screw 23 to rotate. The screw 23 drives the slider 21 to move. The slider 21 drives the glass slide to move synchronously through the electric push rod 12 and the electric suction cup 11, so that the glass slide is moved directly above the microscope sample stage. The electric push rod 12 is started again to place the glass slide in the slot of the sample stage. The electric suction cup 11 is closed to cancel the adsorption of the glass slide. The electric push rod 12 rises, and finally the slider 21 is moved out of the area of ​​the microscope sample stage for Raman detection.

[0045] In summary, the sample transfer and positioning device disclosed in this utility model, suitable for Raman testing, has a simple structure and can automatically place a glass slide with a sample on the microscope sample stage. The movement process is smooth, reducing the risk of sample spillage. Moreover, the device has low cost and is suitable for production use.

[0046] Meanwhile, a support 30 and an operating table 31 are also provided to support and position the glass slide. The guide frame 32 is used to guide the operator to place the sample in the center of the glass slide, so as to avoid the sample placed on the glass slide being tilted, which would cause the sample to spill from the edge of the glass slide.

[0047] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
