[0002] In existing wind turbine generators, blades are a crucial component. To ensure good structural strength for long blades, a main beam and a web are typically installed within the blade, usually bonded together. Simultaneously, the pressure and suction surfaces of the blade are usually manufactured separately, and their connection is also typically bonded. Therefore, the quality of the bonding significantly impacts the overall structural strength of the blade. Before manufacturing the blades, it is usually necessary to use appropriate sample-making equipment to create corresponding bonded test specimens for the aforementioned bonding locations to test their structure, bond strength, stiffness, and other parameters. However, the configuration of the bonded structures in wind turbine blades is quite complex, and the adhesive layer varies widely.

Numerous specific details are set forth in the following detailed description to provide a comprehensive understanding of this application.

[0032] In existing wind turbine generators, blades are a crucial component. To ensure good structural strength for blades with large lengths, they typically incorporate internal components such as main spars and webs to reinforce structural strength. The connection between the main spar and the web is usually achieved through adhesive bonding. Furthermore, the pressure and suction surfaces of the blade are typically manufactured separately, and their connection is also usually achieved through adhesive bonding. Therefore, the performance of the adhesive bonding structure has a vital impact on the overall performance of the blade.

[0033] As blade length increases, blade loads also increase, leading to a rise in the load and failure risk borne by the bonded structure. The structural design and strength verification of such structures are often experimentally based, requiring the fabrication of bonded test specimens to obtain their strength and stiffness properties. Therefore, the quality of the bonded test specimens directly affects the accuracy of the experimental results and consequently the strength verification and final performance of the wind turbine blades.

[0034] Based on this, the applicant found that most existing testing institutions still rely on manual sample preparation, which is inefficient and has poor accuracy. A small number use special tooling to prepare samples for bonded structures, but this tooling still has many problems, including: in the bonding of front and rear edges and the bonding of the main beam web, the dimensions and geometry of the bonded structures vary greatly, making it impossible to use a single tooling to prepare samples for bonding at different locations, requiring the preparation of multiple sets of tooling, which is costly; it is difficult to accurately control parameters such as the thickness of the structural adhesive and the bonding angle of the bonded parts; the human error in the manufacturing process of the bonded parts is large and the quality consistency is poor, affecting the test results, etc.

[0035] To address the aforementioned issues, this application provides a sample preparation device that can be adapted to the manufacture of test samples with different bonding structures, different bonding angles, and different adhesive layer thicknesses. It can also precisely control the size of the test samples, reduce manual operations, and minimize errors.

[0036] It is understood that the following embodiments of this application are only used as examples of the application of the sample preparation device to the manufacture of experimental samples of the bonding structure in wind turbine blades. However, the sample preparation device provided in the embodiments of this application is not limited to the following embodiments. It can also be used to manufacture experimental samples with other connection methods and to manufacture experimental samples of other complex connection structures besides wind turbine blades, and to protect them.

[0037] To better understand this application, the following will be combined with... Figures 1 to 4 The sample preparation apparatus provided in the embodiments of this application will be described in detail.

[0038] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the sample preparation apparatus provided in one embodiment of this application. Figure 2This is a schematic diagram of the sample preparation device provided in another embodiment of this application.

[0039] In a first aspect, according to an embodiment of this application, a sample preparation device 100 is provided for manufacturing a test specimen 200. The test specimen 200 includes a first structural member 101 and a second structural member 102 connected to each other. The sample preparation device 100 includes: a support frame 10, including a base plate 11, a plurality of frame units 12 connected to the base plate 11, and a receiving cavity surrounded by the base plate 11 and the frame units 12, wherein the frame units 12 are at least partially located on one side of the base plate 11 in a first direction X; and a first fixing component 20, located in the receiving cavity and connected to the base plate 11, the first fixing component 20 including a first... The support plate 22, the first connecting member 23, and a plurality of first adjusting members 21 are arranged at intervals between each other and connected between the base plate 11 and the first support plate 22. The size of the first adjusting member 21 in the first direction X is adjustable. The first connecting member 23 is arranged on the side of the first support plate 22 away from the base plate 11 and is used to connect and fix the first structural member 101. The second fixing component 30 is located in the receiving cavity and connected to the support frame 10. The second fixing component 30 is arranged opposite to the first fixing component 20 in the first direction X and is used to connect and fix the second structural member 102.

[0040] This application provides a sample preparation device 100 for manufacturing a test sample 200. The test sample 200 includes a first structural member 101 and a second structural member 102 that are connected to each other. The two need to be connected by a preset connection method and a preset relative position. The following description takes the adhesive connection of the two as an example, but it should be understood that this application is not limited to this.

[0041] The sample preparation device 100 includes a support frame 10, a first fixing component 20, and a second fixing component 30. The support frame 10 is used to provide support and positioning. The first fixing component 20 and the second fixing component 30 are used to support and fix the first structural member 101 and the second structural member 102, respectively. The first fixing component 20 and the second fixing component 30 are arranged opposite to each other along a first direction X. In the process of using the sample preparation device 100, the first direction X can be, for example, a vertical direction.

[0042] The support frame 10 includes a base plate 11, multiple frame units 12 connected to the base plate 11, and a receiving cavity surrounded by the base plate 11 and the frame units 12. This receiving cavity refers to a three-dimensional support structure formed by the base plate 11 as the basic bearing surface and the multiple frame units 12 connected in a detachable or telescopic manner. The receiving cavity provides installation space for the first fixing component 20 and the second fixing component 30. Specifically, it can be implemented using bolted connections or plug-in frame units 12. The size of the receiving cavity can be changed accordingly by adjusting the number or position of the frame units 12.

[0043] Furthermore, the first fixing component 20 includes a first adjusting member 21, a first supporting plate 22, and a first connecting member 23 arranged sequentially along the direction from the base plate 11 to the receiving cavity. There are multiple first adjusting members 21, which are respectively connected between the base plate 11 and the first supporting plate 22. The first adjusting members 21 support the first supporting plate 22 and adjust its angle.

[0044] Specifically, the adjustable size of the first adjusting member 21 in the first direction X can be selected by changing the height of the first adjusting member 21 in the vertical direction through mechanical or hydraulic drive. This can be achieved using a threaded rod and nut structure or a telescopic rod with a hydraulic cylinder. By independently adjusting the height of each first adjusting member 21, the height position of different areas of the first support plate 22 in the first direction X can be controlled, thereby adjusting the tilt angle of the first support plate 22. Multiple first adjusting members 21 are spaced apart from each other; for example, each adjusting member can be distributed at the edge or four corners of the first support plate 22, forming a multi-point independent adjustment mechanism, making the adjustment of the three-dimensional posture of the first support plate 22 and the first structural member 101 connected to the first fixing assembly 20 precise and stable.

[0045] The second fixing component 30 is arranged opposite to and facing the first fixing component 20 in the first direction X. The second fixing component 30 is used to connect the second structural member 102 to support and fix the two structural members in a preset relative position, facilitating subsequent connection. The second fixing component 30 may adopt the same or different structural form as the first fixing component 20.

[0046] When using the sample preparation device 100, the first structural component 101 is fixed to the first connecting component 23, and the height of each of the first adjusting components 21 is adjusted to bring the first structural component 101 to the required spatial orientation. Then, the first structural component 101 is fixed to the second fixing component 30, and the orientation of the second fixing component 30 is adjusted to align the first structural component 101 and the second structural component 102. By precisely controlling the relative positions of the two structural components, accurate bonding can be achieved.

[0047] The sample preparation device 100 in this embodiment can achieve precise control of the spatial attitude of the test sample 200 to be manufactured through a multi-directional independent adjustment mechanism and a cooperative fixing structure. The expandable accommodating cavity of the support frame 10 can adapt to structures of different sizes; the independent height adjustment of multiple first adjustment components 21 can solve the problem of controlling the bonding angle and adhesive layer thickness between two structural components; and the opposing arrangement of the second fixing component 30 further ensures the accurate relative position of the first structural component 101 and the second structural component 102. The synergistic effect of these three elements effectively eliminates human error and improves sample preparation consistency. At the same time, the modular design reduces equipment investment costs, improves sample preparation efficiency, and helps accelerate the iteration speed of blade development.

[0048] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the sample preparation apparatus 100 provided in another embodiment of this application. Figure 4 This is a schematic diagram of the sample preparation device 100 provided in another embodiment of this application.

[0049] In some optional embodiments, the second fixing component 30 is detachably connected to the support frame 10; wherein the second fixing component 30 is slidably connected to the support frame 10, and the second fixing component 30 includes a clamping member 31; or, the support frame 10 further includes a top plate 13, the top plate 13 and the bottom plate 11 are disposed opposite to each other along the first direction X, the second fixing component 30 includes a second adjusting member 33, a second support plate 34 and a second connecting member 35, which are sequentially disposed and interconnected along the direction from the top plate 13 to the bottom plate 11, the second adjusting member 33 is connected to the top plate 13, and the size of the second adjusting member 33 in the first direction X is adjustable.

[0050] Optionally, the second fixing component 30 is detachably connected to the support frame 10, so different structures of the second fixing component 30 can be selected according to the structure and size of the test specimen 200 to be manufactured. For example, in a wind turbine blade, there may be a test specimen 200 for testing the bonding between the web and the main beam and a test specimen 200 for testing the bonding between the leading and trailing edges of the suction and pressure surfaces of the blade. The structural shapes and contact angles of the first structural component 101 and the second structural component 102 in the two test specimens 200 are quite different, so different second fixing components 30 can be selected.

[0051] For example, in an embodiment where a test specimen 200 is manufactured for the connection between the web and the main beam, the second fixing component 30 can be slidably connected to the support frame 10 and connected to the second structural member 102 by clamping. The slidable connection between the second fixing component 30 and the support frame 10 can be achieved by a slide rail or guide groove, etc., and the clamping member 31 can be configured as an adjustable jaw or elastic clamp to adapt to the second structural member 102 of different shapes. In an embodiment where the support frame 10 includes multiple frame units 12, the slide rail can be disposed in some of the frame units 12 and extend in the same direction as them.

[0052] In this embodiment, the first structural member 101 can be a portion of the main beam, and the second structural member 102 can be a portion of the web. After connecting the first structural member 101 to the first fixing component 20, the local structure of the main beam can be positioned in a preset position by the extension and retraction of multiple first adjusting members 21. After connecting the second structural member 102 to the second fixing component 30, the relative positions of the first structural member 101 and the second structural member 102 can be adjusted by sliding the second fixing component 30 relative to the support frame 10. When the two are in the preset relative positions, they are bonded together.

[0053] Alternatively, exemplarily, in an embodiment where samples are prepared at the bonding joint between the front and rear edges of the pressure and suction surfaces of the housing, the second fixing component 30 may adopt the same or similar structural form as the first fixing component 20. Specifically, the support frame 10 may further include a top plate 13, which is disposed opposite to the bottom plate 11 along the first direction X. Similar to the first fixing component 20, the second fixing component 30 includes a second adjusting member 33, a second support plate 34, and a second connecting member 35, which are sequentially arranged and interconnected along the direction from the top plate 13 to the bottom plate 11, and the dimensions of the plurality of second adjusting members 33 are adjustable in the first direction X.

[0054] The relative arrangement of the top plate 13 and the bottom plate 11 can form a vertical adjustment base. By extending and retracting multiple first adjustment members 21 and multiple second adjustment members 33, the angle position of the first support plate 22 and the second support plate 34 can be adjusted respectively, thereby adjusting the relative position and relative angle between the first structural member 101 and the second structural member 102 connected to the two respectively, so as to achieve precise alignment.

[0055] Similar to the first adjusting member 21, the second adjusting member 33 can be a threaded rod or a hydraulic push rod, which changes the angle between the second support plate 34 and the first direction X by screwing or extending. The first connecting member 23 and the second connecting member 35 can be configured as vacuum suction cups, magnetic fixing blocks, grippers, etc., for stabilizing and fixing the first structural member 101 and the second structural member 102. The connection method between the first adjusting member 21, the second adjusting member 33 and the base plate 11 and the top plate 13 can be bolt fixing, snap-fit ​​connection, etc.

[0056] In both of the aforementioned structural schemes, the second fixing component 30 can be disassembled and replaced, for example, through quick-release bolts or plug-in interfaces, allowing the same support frame 10 to be compatible with the alignment requirements of T-shaped structural components in the web of the main beam or the positioning of irregular structures at the front and rear edges. Through the above adjustment mechanism, the bonding angle deviation between the first structural component 101 and the second structural component 102 can be controlled within ±1°, and the fluctuation range of the structural adhesive thickness can be reduced to ±0.2mm, significantly improving the consistency of sample preparation quality.

[0057] In some optional embodiments, the second fixing component 30 is slidably connected to the support frame 10. The plurality of frame units 12 include a first unit 121 extending along the second direction Y and a second unit 122 extending along the third direction Z. The second unit 122 is slidably connected to the first unit 121 and is movable relative to the first unit 121 along the second direction Y. The second fixing component 30 is connected to the second unit 122 and is movable relative to the second unit 122 along the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged to intersect each other, and may further be arranged to be perpendicular to each other.

[0058] In an embodiment where the second fixing component 30 is slidably connected to the support frame 10, the plurality of frame units 12 may include a first unit 121 extending along the second direction Y and a second unit 122 extending along the third direction Z. These two units are slidably connected, allowing the second unit 122 to move along a slide rail disposed on the first unit 121. The slide rails on the first unit 121 and the second unit 122 may extend in the same direction as the frame unit 12 to which they are disposed. The second fixing component 30 is slidably connected to the second unit 122 via the slide rail disposed on the second unit 122, thereby enabling the second fixing component 30 to have degrees of freedom of movement relative to the base plate 11 and the first connecting member 23 along the second direction Y and the third direction Z.

[0059] Specifically, the length of the slide rails on the first unit 121 and the second unit 122 can be set according to the size of the corresponding frame unit 12 and the size of the test sample 200 to be manufactured. The second fixed unit and the second unit 122 can be connected by a slide rail with a dovetail groove structure to provide support along the first direction X while realizing position adjustment.

[0060] For example, locking mechanisms may also be provided on the first unit 121 and the second unit 122 to lock the second unit 122 and the second fixing component 30 after they slide to a preset position, further improving the accuracy and stability of the alignment and bonding of the two structural components. This multi-degree-of-freedom adjustment mechanism can adapt to various geometries without replacing parts or components, significantly improving sample preparation efficiency and consistency.

[0061] In some alternative embodiments, the extension dimension of the second fixing component 30 in the first direction X is adjustable.

[0062] Based on the fact that the second fixing component 30 has the degrees of freedom to move along the second direction Y and the third direction Z, the size of the second fixing component 30 along the first direction X can be adjusted. For example, at least part of the structure in the second fixing component 30 can be extended and retracted along the first direction X, thereby adjusting the position of the second structural member 102 in the first direction X, that is, adjusting the distance between the first structural member 101 and the second structural member 102 along the first direction X.

[0063] The extension and retraction of the second fixing component 30 can be achieved through various structural forms such as telescopic rods, slide rails and locking parts, and buckles. This application does not impose specific limitations on this, as long as the extension size can be adjusted and the component can be stably stopped at the preset length size.

[0064] In some alternative embodiments, the second fixing component 30 includes a telescopic member 32 and a clamping member 31. The telescopic member 32 is connected between the second unit 122 and the clamping member 31. The telescopic member 32 extends at least partially along the first direction X. The clamping member 31 is rotatably connected to the telescopic member 32. The rotation axis of the clamping member 31 is parallel to the first direction X.

[0065] In an embodiment where the first direction X extension dimension of the second fixing component 30 is adjustable, the second fixing component 30 may be further configured to include a telescopic member 32 and a clamping member 31, which are used to adjust the extension dimension and connect with the second structural member 102, respectively. The telescopic member 32 may be a hydraulic telescopic rod or the like, to provide good support and fixing capabilities, and the clamping member 31 may be a claw or the like, to facilitate connection and fixing with the plate-shaped second structural member 102.

[0066] Through the above technical solution, this application achieves the adjustability of the extension dimension of the second fixing component 30 in the first direction X, solving the problem that the limited length of the fixing component makes it impossible to adapt to different thicknesses or bonding angle requirements. This adjustability allows the sample preparation device 100 to flexibly adapt to test samples 200 of various sizes and shapes, ensuring accurate alignment between the first structural component 101 and the second structural component 102.

[0067] Furthermore, the clamping member 31 and the telescopic member 32 can be rotatably connected, allowing the second structural member 102 to adjust its angle. Alternatively, a structure can be adopted where a rotating shaft cooperates with a rotating locking member, allowing the clamping member 31 to rotate relative to the telescopic member 32 while locking itself in a preset position after rotation. By setting the clamping member 31 and the telescopic member 32 as rotatably connected, the flexibility of the second structural member 102's position adjustment can be further improved. Without needing to reposition the angle of the first structural member 101 or adjust the length of the first adjusting member 21, the second structural member 102 and the first structural member 101 can be easily aligned, further improving alignment accuracy and processing efficiency.

[0068] In some alternative embodiments, the support frame 10 further includes a top plate 13, which covers the other along a first direction X, either the orthographic projection of the first support plate 22 or the orthographic projection of the second support plate 34.

[0069] In the embodiment where the second fixing component 30 includes the second adjusting member 33, the second supporting plate 34, and the second connecting member 35, the first supporting plate 22 and the second supporting plate 34 can be arranged facing each other in the first direction X, and the orthographic projection of one of them along the first direction X can cover the orthographic projection of the other, so that the two have sufficient area to be arranged facing each other for mounting the first connecting member 23 and the second connecting member 35, and enabling the first structural member 101 and the second structural member 102 to be aligned and connected.

[0070] For example, the first support plate 22 and the second support plate 34 can have the same shape and size and be positioned opposite each other to facilitate processing. Meanwhile, the areas of the first support plate 22 and the second support plate 34 used to connect the adjusting member can be in the same position to facilitate processing and adjustment of the two fixing components.

[0071] For example, the first support plate 22 may have a larger area than the second support plate 34 to facilitate the support of other auxiliary structures in the sample preparation device 100 and to reduce the weight of the second support plate 34 so that it can support the heavier second structural member 102. The projected area of ​​the first support plate 22 may, for example, be 1.1 to 1.5 times the projected area of ​​the second support plate 34.

[0072] Specifically, when the first support plate 22 is adjusted in height in the first direction X by the first adjusting member 21, the second support plate 34 is simultaneously adjusted by the second adjusting member 33, and the orthographic projection coverage relationship between the two forms a corresponding positioning area. The first structural member 101 is fixed to the first support plate 22 by the first connecting member 23, and the second structural member 102 is fixed to the second support plate 34 by the second connecting member 35. The connection position between the two is constrained by the projection coverage area, so that the axis coincidence deviation is limited to the projection coverage range.

[0073] Through the above technical solution, this application ensures that the connection and positioning areas of the first support plate 22 and the second support plate 34 are directly opposite and overlap each other by limiting the orthographic projection coverage relationship of the first support plate 22 and the second support plate 34 in the first direction X. This can avoid the structural component connection angle deviation or adhesive surface offset caused by the misalignment of the support plates, and at the same time expand the space for aligning and connecting the first structural component 101 and the second structural component 102, making it easier to adapt to different relative positions between the two.

[0074] In some optional embodiments, the first support plate 22 and the second support plate 34 are respectively provided with a first slide rail and a second slide rail, the first connector 23 is slidably connected to the first support plate 22 through the first slide rail, and the second connector 35 is slidably connected to the second support plate 34 through the second slide rail; the first slide rail and the second slide rail extend parallel to each other.

[0075] Optionally, the first support plate 22 and the second support plate 34 may be respectively provided with a first slide rail and a second slide rail, and the first connecting member 23 and the second connecting member 35 may be slidably connected to the corresponding support plate through the aforementioned two slide rails. This facilitates adjustment of the connection position with the first structural member 101 and the second structural member 102.

[0076] For example, the first slide rail can be configured as a groove structure extending along the length of the first support plate 22 and slidingly engaging with the slider disposed on the first connector 23. Ball bearings or a lubricating coating can be added between the slider and the slide rail to reduce the coefficient of friction, such as using a polytetrafluoroethylene coating. Similarly, the second slide rail can have the same cross-sectional shape as the first slide rail, and the first and second slide rails can extend parallel to each other. The extension lengths of the first and second slide rails can be the same or similar to each other to facilitate alignment.

[0077] Optionally, scale markings may be provided on the first and second slide rails or in adjacent areas to more intuitively indicate the positions of the first connector 23 and the second connector 35 on the slide rails, and to facilitate precise adjustment of the two connectors. The first connector 23 and the second connector 35 may be manually moved by an operator, or the first fixing component 20 and the second fixing component 30 may also be provided with mechanical drive components to realize automatic control and remote operation functions of the movement of the two connectors.

[0078] Optionally, the first slide rail and the second slide rail can extend parallel to each other. In terms of bonding angle control, the parallel design of the slide rails allows the first structural member 101 and the second structural member 102 to maintain the included angle during translation. For example, when the two connecting members move a certain distance in the same or opposite direction, the tilt angle of the bonding surface between them can still remain the same as before the movement. This allows for maintaining the flexibility of alignment while maintaining the accuracy of the relative bonding position, and further expands the applicability of the sample preparation device 100.

[0079] In some optional embodiments, the first adjustment member 21 is disposed near the edge of the first support plate 22, and a plurality of first adjustment members 21 are symmetrically distributed along the second direction Y and a plurality of first adjustment members 21 are symmetrically distributed along the third direction Z, with the first direction X, the second direction Y and the third direction Z intersecting each other.

[0080] Optionally, in the first fixing component 20, a plurality of first adjusting members 21 are respectively connected between the first support plate 22 and the base plate 11, and the plurality of first adjusting members 21 can all be disposed close to the edge of the first support plate 22. For example, in an embodiment where the first support plate 22 is circular, the plurality of first support plates 22 can all be disposed close to the outer peripheral surface and can be distributed at equal intervals along the circumference of the first support plate 22; in an embodiment where the first support plate 22 is rectangular, the first adjusting members 21 can be disposed at the four corners of the rectangular plate, for example, one at each of the four corners. By disposing the first adjusting members 21 close to the edge of the first support plate 22, the accuracy of adjusting the pose of the first support plate 22 can be further improved, thereby improving the accuracy and consistency of the test specimen 200.

[0081] Furthermore, the multiple first adjusting members 21 can be symmetrically arranged along the second direction Y and the third direction Z, respectively, with the first direction X, the second direction Y, and the third direction Z intersecting in pairs, or alternatively, arranged perpendicularly in pairs. Taking the first support plate 22 as a rectangular or approximately rectangular example, one of the length direction and the width direction of the rectangular plate can be selected as the second direction Y, and the other is set as the third direction Z. Each of the first adjusting members 21 is symmetrically distributed along both the length and width directions.

[0082] By symmetrically distributing the first adjusting members 21 along the second direction Y and the third direction Z, a bidirectional symmetrical support structure can be formed. When the first support plate 22 is subjected to asymmetrical loads, the symmetrically distributed first adjusting members 21 can disperse stress through a bidirectional balancing mechanism, thereby improving the reliability of the first fixing component 20. Simultaneously, by placing the first adjusting members 21 close to the edge and symmetrically arranging them, the tilt angle of the first support plate 22 can be adjusted more accurately and conveniently, further improving the accuracy of adhesive alignment and the reliability of adhesive strength test data.

[0083] It is understood that in embodiments where the second fixing component 30 includes the second support plate 34 and the second adjusting member 33, the second adjusting member 33 can be set in the same way, that is, it is set close to the edge of the second support plate 34 and symmetrically arranged along the second direction Y and the third direction Z.

[0084] In some optional embodiments, the first fixing component 20 further includes a controller and a plurality of sensors, the plurality of sensors being respectively disposed on a plurality of first adjusting members 21, the sensors being used to detect the extension dimension of the first adjusting members 21 in the first direction X, the controller being communicatively connected to the plurality of first adjusting members 21 and the plurality of sensors, the controller being used to control the extension dimension of the plurality of first adjusting members 21 in the first direction X.

[0085] Optionally, in order to realize the functions of automatic control and remote operation of the first fixed component 20, the first fixed component 20 may include a controller and multiple sensors, wherein the sensors are used to detect the size of each first adjustment member 21 in the first direction X, that is, to detect the height size of the connection point between the first support plate 22 and each adjustment member in the first direction X, so as to obtain the accurate real-time position and orientation of the first support plate 22.

[0086] The controller is communicatively connected to each of the first adjusting components 21 and each sensor. This communication connection refers to a direct connection via signal lines or remote data signal transmission via a signal transceiver module. The controller can acquire monitoring data from each sensor and, based on instructions and the aforementioned data, control the extension and retraction of each adjusting component, thereby adjusting the angle and height of the first support plate 22.

[0087] By setting up sensors and controllers, the ease of operation and accuracy of the first fixing component 20 can be further improved, and the position and orientation of the first support plate 22 can be monitored in real time, thereby improving the alignment and bonding accuracy of the bonding test specimen 200.

[0088] In some alternative embodiments, the first connector 23 includes a gripper, and / or the first connector 23 includes a pressure bar.

[0089] Optionally, the first connecting member 23 can be in the form of a gripper or a pressure bar to facilitate connection and fixation with the first structural member 101. Specifically, to facilitate connection with the first structural member 101, which is a flat plate or irregularly shaped brick, the first connecting member 23 can be in the form of a gripper or pressure bar installed on the first support plate 22.

[0090] In embodiments where the first connector 23 is a gripper, the gripper can hold the first structural member 101 between the gripper and the first support plate 22, or the gripper can hold the first structural member 101 alone. In embodiments where the first connector 23 is a pressure bar, the pressure bar can extend in a straight line, or be configured to have an extension trajectory that matches the first structural member 101 to be gripped.

[0091] Setting the first connector 23 as a gripper or pressure bar can stably connect it to the first structural member 101 and is easy to adapt to first structural members 101 of different sizes and shapes, thus further improving the practicality of the sample preparation device 100.

[0092] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
