Description

Technical fields:

[0001] This invention relates to the field of electron microscope observation device technology, and specifically to an observation fixture for a microscope die-cut product. Background technology:

[0002] Common defects in die-cut products, such as foreign objects, burrs, conductive fabric textures, foam holes, mesh structures, metal sheet cross-sections, and product delamination, all require microscopic observation. Existing microscopes, whether inverted or upright, are typically equipped with only a large platform and a retaining spring, making them only suitable for observing larger objects. Due to the diverse material types and sizes involved in die-cut products, for smaller products (e.g., length / width less than 5mm), conventional microscopes lack dedicated testing fixtures to secure multiple products. Using other adhesive tapes for fixation makes it difficult to obtain the required field of view, and the product cannot be accurately and stably placed under the objective lens. Furthermore, target location is time-consuming, resulting in low testing efficiency and making the analysis of these products quite challenging.

[0003] While existing technologies include observation fixtures for small-sized products, such as the "A Biological Experiment Auxiliary Device for Leaf Structure Observation" (publication number CN209842216U) and the "A Sample Tray for an Inverted Metallurgical Microscope" (publication number CN215006060U), these fixtures cannot meet the observation and testing needs of small-sized die-cut products due to the different products being observed. The applicant has also developed an "Optical Detection Fixing Device and Detection Instrument" (publication number: CN217237741U), which also suffers from problems such as inconvenient use and adjustment, and low observation and testing efficiency. Summary of the Invention:

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a microscope die-cutting product observation fixture.

[0005] The technical solution adopted in this invention is: a microscope die-cut product observation fixture, which includes a pair of vertical support plates, a transverse shaft mounted on the pair of vertical support plates, and a rotating material carrier wheel mounted on the transverse shaft. The rotating material carrier wheel is provided with a material carrier area for loading the sample to be observed, and the material carrier area is provided with an observation port for the sample to be observed to be exposed.

[0006] Furthermore, the loading area and the loading wheel are separate structures, that is, the loading area includes a detachable loading card, which is provided with an observation port and a light transmission port opposite to the observation port.

[0007] As one embodiment, the detachable cargo carrier and the cargo wheel are connected by a sliding groove and a sliding rail mechanism. That is, the detachable cargo carrier has sliding grooves on both sides, and an array of sliding rails is provided on the outer cylindrical surface of the cargo wheel. Each set of sliding rails is equipped with a detachable cargo carrier. The position of the detachable cargo carrier can be adjusted along the direction of the sliding rail. The surface where the observation port is located is parallel to the axis, which is suitable for vertical observation.

[0008] Alternatively, the detachable cargo card and the cargo wheel are connected by a magnetic attraction mechanism.

[0009] Furthermore, the detachable sample carrier has a rectangular flat body with a through sample channel formed on a set of opposite surfaces of the flat body. The sample channel is provided with an elastic clip, and the outer walls on both sides of the sample channel are respectively formed with grooves. The upper and lower outer walls of the sample channel are respectively provided with observation ports and light-transmitting ports, and the inner walls of the two side grooves are also respectively provided with light-transmitting ports.

[0010] Furthermore, the detachable sample carrier is equipped with an elastic clip for positioning the sample to be observed.

[0011] In another embodiment, several radial slots are provided on the outer cylindrical surface of the cargo wheel 3, and a slide rail is provided in the radial slot. The detachable cargo card is inserted into the radial slot, and the detachable cargo card is provided with a slide groove corresponding to the slide rail.

[0012] The sample-carrying area is equipped with elastic clips for positioning the sample to be observed.

[0013] Furthermore, a locking mechanism is provided between the load-carrying wheel and the transverse shaft. The locking mechanism consists of a locking ring protruding from one end face of the load-carrying wheel, a locking block and a locking screw that radially penetrate the locking ring and abut against the transverse shaft, and connecting rods are respectively connected to both ends of the bottom of the vertical support plate.

[0014] One end of the transverse shaft is also provided with a positioning drive mechanism for controlling the angle of the rotating cargo wheel.

[0015] The rotating object carrier is provided with a light-transmitting window corresponding to the observation port. The rotating object carrier includes an inner rim passing through a transverse shaft, a support spoke connected to the inner rim, and an outer rim connected to the support spoke. The outer rim is provided with several light-transmitting windows; a light source is also installed around the inner rim.

[0016] The observation fixture of this invention adopts the above-described structure, allowing multiple small-sized products to be observed to be positioned on the rotating platform. After adjusting the field of view of the microscope, there is no need to adjust the microscope again. By rotating the rotating platform, different products on the platform can be observed continuously, thereby greatly improving the efficiency of observation and detection. Moreover, the observation fixture of this invention is applicable to various shapes of samples to be observed and to different types of microscopes, meeting the observation needs of horizontal, vertical or other angles.

[0021] Figure 7 This is a schematic diagram of the structure of Embodiment 4 of the present invention. Detailed implementation method:

[0022] like Figures 1-3 As shown, the present invention relates to a microscope die-cut product observation fixture, which includes a pair of vertical support plates 1, a transverse shaft 2 mounted on the pair of vertical support plates 1, and a rotating material carrier wheel 3 mounted on the transverse shaft 2. The rotating material carrier wheel 3 is provided with a material carrier area 4 for loading the sample to be observed, and the material carrier area 4 is provided with an observation port 401 for exposing the sample to be observed.

[0023] Combination Figure 1 The number of sample-carrying wheels 3 on the transverse axis 2 is one or more, and the position of the sample-carrying wheels 3 relative to the transverse axis 2 can be adjusted as needed. The sample-carrying wheels 3 can rotate together with the transverse axis 2, or they can rotate around the transverse axis 2 as a pivot. Through their rotation, the observation port 40 on the sample-carrying area 4 can be used in conjunction with the microscope to observe and detect the sample on it. Furthermore, combined with Figure 3As shown, a locking mechanism 5 is provided between the load-carrying wheel 3 and the horizontal shaft 2. Connecting rods 11 are also connected to both ends of the bottom of the vertical support plate 1, making the entire support structure more stable and not affecting the bottom lighting. In this embodiment, the vertical support plate 1 is trapezoidal in shape, with an opening at the top for mounting the horizontal shaft 2. The horizontal shaft 2 can be connected to the vertical support plate via a bearing (not shown in the figure). The locking mechanism 5 consists of a locking ring 51 protruding from one end face of the load-carrying wheel 3, a locking block 52 radially inserted into the locking ring 51 and contacting the horizontal shaft, and a locking screw 53. The locking mechanism 5 can be located at the left or right end of the load-carrying wheel 3.

[0024] Furthermore, the loading area 4 and the loading wheel 3 are separate structures, that is, the loading area 4 includes a detachable loading card 41, which is provided with an observation port 401 and a light transmission port 402 opposite to the observation port 401. In this invention, the detachable loading card 41 has a symmetrical structure as a whole, and the observation port 401 and the light transmission port 402 are also symmetrical, which makes it convenient to choose any insertion direction when using it.

[0025] As one embodiment, the detachable cargo carrier 41 is connected to the cargo wheel 3 via a sliding groove and a sliding rail mechanism. That is, sliding grooves 411 are provided on both sides of the detachable cargo carrier 41, and an array of sliding rails 31 are provided on the outer cylindrical surface of the cargo wheel 3. A detachable cargo carrier 41 is installed on each set of sliding rails 31. The position of the detachable cargo carrier 41 can be adjusted along the direction of the sliding rail 31. The surface where the observation port 401 is located is parallel to the axial direction, which is suitable for vertical observation.

[0026] Alternatively, the detachable cargo card 41 and the cargo wheel 3 are connected by a magnetic attraction mechanism (not shown in the figure).

[0027] Combination Figures 4-6 As shown, the detachable sample carrier 41 further comprises a rectangular flat body with a through sample channel 412 formed along a set of opposing surfaces. Two elastic clips 413 are provided on both sides of the sample channel 412. The elastic clips 413 have an arc-shaped structure for positioning the sample to be observed. The structure is simple and facilitates product positioning and removal. The outer walls of both sides of the sample channel 412 are respectively formed with grooves 411. The upper and lower outer walls of the sample channel 412 are respectively provided with observation ports 401 and light-transmitting ports 402. The inner walls of the two side grooves 411 are also respectively provided with light-transmitting ports 402 to allow sufficient light to enter, thus providing sufficient light to support observation and facilitating product loading and unloading.

[0028] In another embodiment, several radial slots 32 are formed on the outer cylindrical surface of the load-carrying wheel 3, and slide rails 31 are provided in the radial slots 32. The slide rails 31 in the radial slots 32 are connected to... Figure 1In this embodiment, the slide rails 31 on the outer cylindrical surface are of the same specification. The detachable cargo card 41 is inserted into the radial slot 32. The detachable cargo card 41 is provided with a slide groove corresponding to the slide rail. In this embodiment, the slide groove on one side of the detachable cargo card 41 cooperates with the slide rail in the radial slot, thereby adjusting the position of the detachable cargo card in the radial slot. The plane where the observation port is located is arranged radially, which is suitable for horizontal observation.

[0029] exist Figure 1 Based on the previous embodiment, namely in this embodiment, the detachable cargo carrier 41 can be connected and assembled with the cargo wheel 3 in two ways, so it can be used for both horizontal and vertical observation.

[0030] One end of the transverse shaft 2 is also provided with a positioning drive mechanism 21, which is used to control the angle of the rotating sample wheel 3, so that the observation port 401 of the detachable sample holder 41 is parallel to the objective lens and fixed for easy observation. The positioning drive mechanism 21 can be a positioning drive wheel or an incomplete gear set. The positioning drive mechanism drives the transverse shaft 2 and the sample wheel 3 to rotate, thereby rotating the sample on the sample wheel 3 to a suitable observation position.

[0031] For example Figure 7 As shown, in this embodiment, the cargo-carrying wheel 3 is provided with light-transmitting windows 301 corresponding to the observation port 401 and the light-transmitting port 402. The cargo-carrying wheel 3 includes an inner wheel rim 302 passing through the transverse shaft 2, a support wheel spoke 303 connected to the inner wheel rim 302, and an outer wheel rim 304 connected to the support wheel spoke 303. The outer wheel rim 304 is provided with several light-transmitting windows 301, and each light-transmitting window 301 has slide rails 31 on both sides connected to the detachable cargo carrier 41. A light source 305 is also installed around the inner wheel rim 3. The light source 305 is preferably arranged to radiate outwards in a circular direction to illuminate each light-transmitting window 301, or multiple light sources are arranged according to the number and position of the light-transmitting windows 301.

[0032] The observation fixture of this invention adopts the above-described structure, allowing multiple small-sized products to be observed to be positioned on the rotating platform. After adjusting the field of view of the microscope, there is no need to adjust the microscope again. By rotating the rotating platform, different products on the platform can be observed continuously, thereby greatly improving the efficiency of observation and detection. Moreover, the observation fixture of this invention is applicable to various shapes of samples to be observed and to different types of microscopes, meeting the needs of horizontal, vertical or other angle observation.

[0033] In summary, the observation fixture of this invention is beneficial for the observation and testing of small-sized products. It has a simple structure, is easy to use and has low cost. It can significantly improve the efficiency of sample observation and testing, and is applicable to products of various shapes and microscopes of various types, thus having wide applicability.
