Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to oscillation devices and experimental equipment. Background Technology

[0002] In chemical, biological and other experiments, the issue of uniformly mixing solutions is always involved. When the quantity is small, manual shaking is generally used; when the quantity is large, a shaking device or equipment is used for shaking.

[0003] The oscillation devices in related technologies have low maximum speed and load, and short single oscillation time. For example, the maximum speed is usually only 500 rpm, the load is often below 300g, and the single oscillation time is generally less than 1 hour. Therefore, they are difficult to meet the experimental requirements of high speed, large load and long oscillation time. Summary of the Invention

[0063] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0065] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0066] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0067] In related technologies, oscillators using three eccentric shafts to achieve rotational vibration employ one eccentric shaft as the drive shaft, driving the other two eccentric shafts to rotate, thus achieving the oscillation effect. Since this type of oscillator uses one shaft to drive two others, a counterweight needs to be added to the drive shaft. Furthermore, adding a counterweight to a single eccentric drive shaft requires additional space for the counterweight's rotation, as well as additional components such as a chassis to stabilize the oscillator. Moreover, during oscillator operation, the counterweight does not rotate around its geometric center, causing the drive shaft to withstand not only radial pressure but also the horizontal pressure generated by the counterweight's rotation, placing high strength requirements on the drive shaft. Therefore, the rotational speed and load of this type of oscillator cannot be too high; otherwise, excessive centrifugal force generated by the counterweight will affect the lifespan of the drive shaft, and consequently, the lifespan of the oscillator. For experiments requiring extensive oscillation, this type of oscillator is insufficient and cannot sustain prolonged oscillation.

[0068] To address the aforementioned issues, this application provides an oscillation device and experimental equipment that can improve the operational stability of the oscillation device during high-speed and long-term oscillation, thus meeting the experimental requirements for high-speed, high-load, and long-term oscillation.

[0069] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0070] Figure 1 This is a schematic diagram of the structure of the oscillation device shown in the embodiments of this application; Figure 2 yes Figure 1 The diagram shows the installation schematic of the rotating component of the oscillation device.

[0071] See Figure 1 and Figure 2The oscillation device provided in this application includes a base plate 110 and three rotating parts 111 rotatably mounted on the base plate 110. The base plate 110 has a support plate 130 on its upper side and a counterweight 120 on its lower side. The two ends of the rotating parts 111 are located on the upper and lower sides of the base plate 110, respectively, and are fixedly connected to the support plate 130 and the counterweight 120 through an eccentric structure. The device also includes a drive device. The three rotating parts 111 are located at the three vertices of a virtual triangle. The output shaft 141 of the drive device is perpendicular to the virtual triangle and is connected to the three rotating parts 111 for driving the three rotating parts 111 to rotate synchronously. In this embodiment, when the oscillation device is running, the three rotating parts 111 can drive the support plate 130 to oscillate. Since the counterweight 120 is located at the bottom of the three rotating parts 111 and is fixedly connected to the three rotating parts 111 through an eccentric structure, the centrifugal force generated by the counterweight 120 can be shared by the three rotating parts 111. This not only allows it to bear a larger oscillation load, but also improves the operational stability of the oscillation device during high-speed and long-term oscillation, thus meeting the experimental requirements of high speed, large load and long-term oscillation.

[0072] Compared with the existing scheme in which the counterweight is connected to only one rotating component in the oscillator, this application connects the counterweight 120 to three rotating components 111 at the same time. This is more stable in terms of installation, and can withstand greater load and speed. It also reduces the strength requirements of the rotating components 111, and during the oscillation operation, it is less likely for the rotating components to suffer physical fatigue (deformation) and affect the life of the entire oscillation device. As a result, the stability of the entire oscillation device is better, and it can work continuously for a long time.

[0073] Figure 3 yes Figure 1 A three-dimensional structural schematic diagram of the rotating component 111 of the oscillation device is shown in the figure; Figure 4 yes Figure 1 The side view of the rotating component 111 of the oscillation device shown in the figure.

[0074] See Figures 1 to 4 In some embodiments, the rotating component 111 includes a shaft 1110, with a first eccentric connecting shaft 1111 and a second eccentric connecting shaft 1112 at both ends of the shaft 1110. The rotating component 111 is connected to the support plate 130 via the first eccentric connecting shaft 1111 and to the counterweight 120 via the second eccentric connecting shaft 1112. The axis of the first eccentric connecting shaft 1111 and the axis of the second eccentric connecting shaft 1112 are parallel to the axis of the shaft 1110 and are located on the radial sides of the shaft 1110, respectively.

[0075] In some embodiments, the first eccentric connecting shaft 1111 of the rotating member 111 is connected to the support plate 130 via the upper bearing seat 131, and the second eccentric connecting shaft 1112 is connected to the counterweight 120 via the lower bearing seat 122. The driving device can drive the three rotating members 111 to rotate. When the three rotating members 111 rotate, the upper support plate 130 can be moved via the first eccentric connecting shaft 1111, and the lower counterweight 120 can be moved via the second eccentric connecting shaft 1112. Since the first eccentric connecting shaft 1111 and the second eccentric connecting shaft 1112 are located on the radial sides of the shaft 1110 of the rotating component 111, when the movement directions of the support plate 130 and the counterweight 120 are opposite, the counterweight 120 can buffer the centrifugal force generated by the support plate 130. At the same time, the support plate 130 can also buffer the centrifugal force generated by the counterweight 120, thereby improving the operational stability of the oscillation device. It can not only meet the requirements of high-speed oscillation, such as the maximum movement of the support plate 130 reaching 1200 rpm; but also meet the requirements of long-term oscillation, such as the ability to conduct oscillation experiments for up to 48 hours; and can also withstand larger oscillation loads, such as oscillation loads up to 2 kg.

[0076] In some embodiments, since the rotating component 111 needs to withstand axial and radial forces, in order to ensure the strength of the rotating component 111, the first eccentric connecting shaft 1111 and the second eccentric connecting shaft 1112 can be formed as one piece, which can improve the overall structural strength of the rotating component 111. In some embodiments, the rotating component 111 is made of a high-strength metal material, such as including but not limited to 303 stainless steel.

[0077] In this embodiment, when the rotating component 111 drives the counterweight 120 to rotate, the counterweight 120 generates centrifugal force. The faster the rotation speed, the greater the centrifugal force generated, and the greater the radial force exerted by the counterweight 120 on the rotating component 111. In this embodiment, since all three rotating components 111 are connected to the counterweight 120 and are buffered by the connection of the lower bearing seat 122, the radial force exerted by the counterweight 120 on the rotating component 111 is reduced, thus improving the lifespan of the rotating component 111.

[0078] The driving device may include a motor 140. A drive pulley 1411 is mounted on the output shaft 141 of the motor 140, and three rotating components 111 are each mounted with a driven pulley 1114. The output shaft 141 of the motor 140 is connected to the three rotating components 111 via a flexible transmission component 150, which is wound around the drive pulley 1411 and the three driven pulleys 1114. The flexible transmission component 150 includes a double-sided toothed synchronous belt. When the drive pulley 1411 rotates, it can drive the three driven pulleys 1114 to rotate synchronously via the double-sided synchronous belt. Using a synchronous belt drive reduces the noise generated during the oscillation process and also reduces the phase error of the three rotating components 111 caused by processing and assembly, ensuring the operating accuracy of the oscillation device.

[0079] In this embodiment, the three rotating components 111 have identical structures, and the virtual triangle is an isosceles triangle. The output shaft 141 passes through the center of gravity of the virtual triangle. This arrangement ensures that when the drive wheel 1411 rotates, the number of teeth rotating on each side of the virtual triangle corresponding to the double-sided toothed synchronous belt is the same, reducing shaking and increasing stability of the oscillation device during operation. Furthermore, compared to related technologies, the reserved space for the rotation of the counterweight 120 is reduced, eliminating the need for components such as a chassis for stabilizing the oscillation device. This saves space, reduces costs, and lowers the overall weight and size of the oscillation device, allowing multiple oscillation devices to be placed on a test bench of the same area, facilitating simultaneous different oscillation experiments. Additionally, the above structural arrangement allows the eccentric oscillation of the support plate 130 and the material it carries to cancel out the eccentric oscillation of the counterweight 120, thereby improving the stability of the oscillation device.

[0080] In some embodiments, the eccentricity of the rotating member 111 is the same, that is, the distance from the axis of the shaft 1110 of the rotating member 111 to the axis of the first eccentric connecting shaft 1111 of the rotating member 111 is equal to the distance to the axis of the second eccentric connecting shaft 1112 of the rotating member 111. This makes the amplitude of the support plate 130 and the counterweight 120 the same. For example, the eccentricity can be 2.5 mm and the amplitude can be 5 mm. This can further improve the stability of the oscillation device.

[0081] In some embodiments, when installing the three rotating members 111, the phases of the three rotating members 111 can be made consistent, which can ensure that the three rotating members 111 rotate synchronously and improve the stability of the oscillation device.

[0082] With the above-mentioned structural configuration, when the oscillating device is working, the support plate 130 and the material it carries will generate a horizontal force, while the counterweight 120 will generate a force in the opposite direction. They can cancel each other out, thereby achieving the stability of the entire oscillating device during rotation.

[0083] In some embodiments, the drive device is movably disposed relative to the base plate 110; a tension adjustment mechanism is provided between the motor 140 and the base plate 110, which is used to adjust the relative position between the drive wheel 1411 and the three driven wheels 1114 to adjust the tension of the flexible transmission member 150, so as to avoid the flexible transmission member 150 from loosening after long-term operation.

[0084] In some embodiments, the motor 140 is fixed to the mounting plate 142, which is movably disposed relative to the base plate 110. The tension adjustment mechanism includes an adjusting block fixed to the base plate 110, a tension adjusting block 143 fixed to the mounting plate 142, and a threaded adjusting member connecting the adjusting block and the tension adjusting block 143. The adjusting block and the tension adjusting block 143 may be located at the bottom of the base plate 110 and on one side of the motor 140.

[0085] The threaded adjustment component can be a screw connected between the adjusting fixed block and the tension adjusting block 143. Rotating the screw causes relative movement between the adjusting fixed block and the tension adjusting block 143, which in turn causes relative movement between the motor 140 and the base plate 110. This results in a slight change in the distance between the driving wheel 1411 and the three driven wheels 1114, thereby achieving the purpose of adjusting the tension of the flexible transmission component 150. The tension adjusting mechanism also stabilizes the motor 140, preventing the output shaft 141 of the motor 140 from shifting due to the tension of the synchronous belt.

[0086] In some embodiments, a first hollow portion 112 may be formed in the middle of the base plate 110, and a second hollow portion 121 may be formed in the middle of the counterweight block 120; the first hollow portion 112 and the second hollow portion 121 are vertically opposite each other, and the motor 140 includes a main body connected to the output shaft 141, the output shaft 141 passing through the first hollow portion 112, and the main body passing through the second hollow portion 121. This arrangement makes the structure of the oscillation device more compact, which can reduce the space occupation and the weight of the oscillation device.

[0087] In some embodiments, the oscillation device further includes a switch component 113 for limiting the rotational position of the rotating member 111. The switch component 113 can be installed on the upper side of the base plate 110. Simultaneously, a limiting member 1113 cooperating with the switch component 113 can be provided on the shaft 1110 of the rotating member 111, so that after the oscillation device has finished working, the support plate 130 can stop at a specific position or the limiting member 1113 of the rotating member 111 can stop at a specific position. The switch component 113 may include a photoelectric switch, but is not limited to this. In addition, the limiting member 1113 also serves to balance the rotating member 111. When the rotating member 111 is installed, the portion located on the lower side of the base plate 110 is longer than the portion located on the upper side of the base plate 110, resulting in an uneven weight distribution and potential wobbling during rotation. Adding the limiting member 1113 on the upper side of the rotating member 111 balances the weight of the upper and lower parts, ensuring greater stability during rotation.

[0088] Figure 5 This is a schematic diagram of the installation structure of the container support device for the oscillation device shown in the application embodiment.

[0089] See Figure 5 The oscillation device of this application also includes a container carrying device, which is connected to the tray 130. The container carrying device is provided with a plurality of container placement slots 211, and elastic limiting members 230 are installed in the container placement slots 211 to limit the containers within the container placement slots 211. The containers can be test tubes, but are not limited to them. When the tray 130 moves, it can drive the container carrying device to move, thereby oscillating the solution in the container.

[0090] Figure 9 This is a schematic diagram of the structure of the elastic limiting member of the oscillation device shown in the embodiments of this application.

[0091] See Figure 9 In some embodiments, the elastic limiting member 230 is made of a metal material with elastic deformation capability. The elastic limiting member 230 includes a fixed part 231 and a movable part 232 that is integral with the fixed part 231 and can move elastically relative to the fixed part 231. The fixed part 231 is fixedly disposed relative to the container carrying device, for example, it can be fixed to the slot 2111 of the container placement slot 211 by screws. The movable part 232 is received in the container placement slot 211 and is used to elastically abut against the outer wall of the container placed in the container placement slot 211, thereby limiting the container.

[0092] In some embodiments, the container placement slot 211 is opened from top to bottom on the top of the container carrier. An opening is provided on the upper side of the container placement slot 211. The diameter of the container placement slot 211 can be larger than the diameter of the container. The test tube can be placed into the container placement slot 211 from top to bottom through the opening. The elastic limiting member 230 is housed in the gap between the container and the inner wall of the container placement slot 211. The movable part 232 can elastically abut against the outer wall of the test tube, preventing relative movement between the test tube and the container mounting slot.

[0093] In some embodiments, the movable part 232 can be provided as two, and they are spaced apart to form a gap 233, so that the elastic limiting member 230 is U-shaped. The two movable parts 232 can simultaneously elastically abut against the outer wall of the container, which has a better limiting effect on the container.

[0094] The elastic limiting component 230 not only prevents the container from breaking due to movement during oscillation, but also ensures that the container itself does not vibrate due to inertia during oscillation, moving along with the container support device throughout the process, thus making the oscillation efficiency of the solution higher. In addition, when the oscillation speed is stable, state detection (such as solubility state, crystallization state, etc.) can be performed, which can keep the substance in the container in a relatively stable state, which is conducive to obtaining more accurate detection results.

[0095] The container carrying device of this embodiment includes a base 210 with a plurality of container placement slots 211, and the base 210 is made of a thermally conductive material.

[0096] Figure 6 yes Figure 5 A schematic diagram of the installation structure of the temperature control component of the oscillation device.

[0097] See Figure 5 and Figure 6 The oscillation device of this application also includes a temperature control component, which includes a heating element 310 installed on the substrate 210. The heat generated by the heating element 310 can be transferred to the solution in the container through the substrate 210, thereby achieving heating of the solution.

[0098] In some embodiments, the material of the substrate 210 may include aluminum, but is not limited to it. For example, it may also be made of other materials with good thermal conductivity, such as gold, silver, copper, carbon fiber, etc.

[0099] The heating element 310 can be a sheet-like heating element attached to the substrate 210, such as a PI (Polyimide) heating film. The PI heating film uses a polyimide film as the outer insulator and a nickel-chromium alloy etched heating element as the inner conductive heating element.

[0100] In some embodiments, the temperature control assembly also includes a pressure plate 320 for fixing the heating film to the substrate 210. The heating film can be bonded to the pressure plate 320, and the pressure plate 320 can be fixed to the bottom of the substrate 210 using screws or other connectors, so that the heating film is sandwiched between the pressure plate 320 and the bottom of the substrate 210.

[0101] In some embodiments, a heat insulation block 360 is provided between the substrate 210 and the tray 130. The heat insulation block 360 is made of a material with good heat insulation properties, such as PPS (polyphenylene sulfide). The heat insulation block 360 can prevent the heat generated by the heating element from being conducted to other parts of the oscillation device, such as the tray 130, thereby preventing the parts of the oscillation device from being affected by excessive temperature.

[0102] In some embodiments, the temperature control component also includes a temperature sensor 330, which can sense the temperature information of the substrate 210 in real time, making the collected temperature data more accurate, for example, the temperature accuracy error can be controlled within ±0.2℃.

[0103] The temperature sensor 330 can be fixed in the base 210 with screws. It is understood that this application does not limit the installation position of the temperature sensor 330. The temperature sensor 330 can also be installed near the container placement slot 211 or near the heating element 310.

[0104] In some embodiments, the temperature control component further includes a temperature protection switch 340, which includes a switch plate 350 that presses against the substrate 210. When the temperature exceeds a set threshold, the temperature protection switch 340 can directly cut off the power supply to the heating element 310, causing the heating element 310 to stop heating the substrate 210.

[0105] In some embodiments, the temperature control assembly further includes a temperature controller electrically connected to the temperature sensor 330 and the temperature protection switch 340. The temperature controller can monitor the temperature information of the substrate 210 and control the temperature of the substrate 210 within a set range, such as 25 to 150°C.

[0106] In some embodiments, the oscillation device of this application further includes a first detection device, which is used to perform laser detection on the substance in the container carried by the container carrier. For example, the clarity of the solution can be detected in real time by laser. Based on the detected clarity, the current degree of reaction of the solution can be determined, and the oscillation speed and oscillation time of the oscillation device can be adjusted in a timely manner, realizing a closed-loop experimental process. This reduces the steps of "stopping the oscillator", "removing the test tube", "detecting the clarity of the solution" and "re-oscillating" in related technologies, shortens the experimental time, and saves experimental costs.

[0107] In some embodiments, the first detection device includes a laser emitting module and a laser receiving module 430 respectively disposed on both sides of the container carrier. The laser beam emitted by the laser emitting module passes through the container placement slot 211 and can be received by the laser receiving module 430. A laterally penetrating channel 2112 can be opened on the substrate 210 corresponding to the container placement slot 211. The laser beam emitted by the laser emitting module can irradiate the solution in the container through the channel 2112 and be received by the laser receiving module 430, thereby realizing the detection of the clarity of the solution.

[0108] In addition, when the U-shaped elastic limiting member 230 is installed, its gap 233 is aligned with the channel 2112 on the base 210. This is beneficial for the first detection device to detect the state of the substance in the container (e.g., test tube) in the container placement slot by laser detection, thereby realizing the detection of the state of the substance in the container.

[0109] See Figure 7 The laser receiving module 430 includes a laser receiving plate 431. At least one side of the laser receiving plate 431 is provided with multiple laser receiving elements. At least one side of the laser receiving plate 431 is sequentially connected to a reinforcing plate 432, a diffusion film 433, and a light-shielding plate 435. The reinforcing plate 432 increases the rigidity of the laser receiving module 430. The diffusion film 433 causes the point source of the laser to form a regional light spot, making it easier for the laser receiving plate 431 to receive the laser signal. The light-shielding plate 435 prevents other light from shining onto the laser receiving plate 431. The light-shielding plate 435 is made of a material with good light-shielding properties, such as stainless steel.

[0110] In some embodiments, the laser receiving plate 431, reinforcing plate 432, diffusion film 433, and light-shielding plate 435 can be fixed together by adhesive. For example, an adhesive connector 434, such as double-sided tape, can be applied between the laser receiving plate 431 and the reinforcing plate 432 to bond them together. Double-sided tape can also be applied between the reinforcing plate 432 and the diffusion film 433 to bond them together; similarly, double-sided tape can be applied between the diffusion film 433 and the light-shielding plate 435 to bond them together. It is understood that the laser receiving plate 431, reinforcing plate 432, diffusion film 433, and light-shielding plate 435 are not limited to being fixed by adhesive, or limited to being bonded by double-sided tape; they can also be connected by connectors such as screws.

[0111] See Figure 7 and Figure 8In some embodiments, the laser emitting module includes a laser emitting plate and a connecting plate. The laser emitting plate is fixed to the base 210 of the container carrying device via the connecting plate, for example, by screws. The laser element of the laser emitting plate is fitted with multiple rubber rings, which can be fluororubber gaskets.

[0112] In some embodiments, the multiple container placement slots 211 are divided into at least two groups on the container carrying device; each group of container placement slots 211 is provided with a laser emitting module and a laser receiving module 430 on both sides.

[0113] In some embodiments, multiple container placement slots 211 are divided into two groups arranged side-by-side on the container carrier; the laser emitting module includes a left laser emitting module 410 and a right laser emitting module 420 installed on both sides of the container carrier, and a laser receiving module 430 is installed between the two groups of container placement slots 211; wherein, one side of the laser receiving plate 431 is provided with a laser receiving element corresponding to the left laser emitting module 410, and the other side is provided with a laser receiving element corresponding to the right laser emitting module 420. In this embodiment, both sides of the laser receiving plate 431 are sequentially connected to a reinforcing plate 432, a diffusion film 433, and a light-shielding plate 435, respectively. See also Figure 7 The left laser emitting module 410 includes a left laser emitting plate 411, a left connecting plate 412, and a connecting block 413. The left laser emitting plate 411 is connected to the left side of the left connecting plate 412, for example, by screws. The connecting block 413 is located on the right side of the left connecting plate 412, and is connected to the left side of the laser receiving module 430 via the connecting block 413. The left laser emitting plate 411 can be fixed to the container carrier device via a threaded connection to the left connecting plate 412. See also... Figure 8 The right laser emitting module 420 includes a right laser emitting plate 421 and a right connecting plate 422. The right laser emitting plate 421 is connected to the right side of the right connecting plate 422, for example, by screw connection and fixation. The right laser emitting plate 421 is connected to the right side of the container carrying device through the right connecting plate 422.

[0114] In some embodiments, a left rubber ring 414 is fitted onto the laser emitting element of the left laser emitting plate 411, and a right rubber ring 423 is fitted onto the laser emitting element of the right laser emitting plate 421. The left rubber ring 414 and the right rubber ring 423 provide a sealing effect for the laser emitting elements. In some embodiments, the laser receiving module 430 and the left laser emitting module 410 can be integrated and mounted integrally on the container carrier. It is understood that the laser receiving module 430 and the right laser emitting module 420 can also be integrated; alternatively, the left laser emitting module 410, the right laser emitting module 420, and the laser receiving module 430 can be integrated.

[0115] In some embodiments, the oscillation device of this application further includes a second detection device, which is used to acquire images of the substance in the container carried by the container carrier. The state of the substance, such as crystallization state or dissolved state, can be detected by the images acquired by the second detection device. The state of the substance can be verified and supplemented by the state of the substance detected by the first detection device, which is conducive to obtaining more accurate detection results.

[0116] Figure 10 This is a schematic diagram of the structure of the second detection device of the oscillation device shown in the embodiments of this application; Figure 11 This is a schematic diagram of the overall structure of the oscillation device shown in the embodiments of this application.

[0117] See Figure 10 and Figure 11 In some embodiments, the second detection device includes an image acquisition component 600, which may be, for example, a camera.

[0118] The second detection device in this application embodiment can collect image information of the substance inside the container from the top, bottom, or around the container. The following example of collecting image information from the bottom of the container illustrates the solution of this application.

[0119] In this embodiment, an active space 221 is provided between the container carrying device and the tray 130, allowing the image acquisition component 600 to move. The container carrying device and the tray 130 are connected by a support frame 220, which has a preset height, thereby forming an active space 221 at the bottom of the container carrying device. The image acquisition component 600 can move in the active space 221, thereby acquiring image information of multiple substances inside the containers.

[0120] The second detection device also includes a motion mechanism, on which the image acquisition component 600 is mounted. The motion mechanism is used to drive the image acquisition component 600 to move in at least one degree of freedom.

[0121] In some embodiments, a motion mechanism is used to drive the image acquisition component 600 to move in three degrees of freedom; wherein, the motion mechanism includes a support portion 510, a first track 520 disposed on the support portion 510, a first sliding component 540 slidably mounted on the first track 520, a second track 550 disposed on the first sliding component 540, a second sliding component 570 slidably mounted on the second track 550, a third track 580 disposed on the second sliding component 570, and a third sliding component 590 slidably mounted on the third track 580, and the image acquisition component 600 is mounted on the third sliding component 590; wherein, the first track 520, the second track 550, and the third track 580 are set to correspond to the three coordinate axes of a spatial rectangular coordinate system, for example, the first track 520 is set along the X-axis, the second track 550 is set along the Z-axis, and the third track 580 is set along the Y-axis.

[0122] See also Figure 10 and Figure 11 In some embodiments, the motion mechanism further includes three driving members for driving the first sliding assembly 540, the second sliding assembly 570, and the third sliding assembly 590 respectively. These driving members may be, for example, lead screw motors, including an X-axis lead screw motor 530, a Z-axis lead screw motor 560, and a Y-axis lead screw motor 581. The X-axis lead screw motor 530 is fixedly disposed relative to the first track 520, the Z-axis lead screw motor 560 is fixedly disposed relative to the first sliding assembly 540, and the Y-axis lead screw motor 581 is fixedly disposed relative to the third track 580. The support portion 510 may include a plate-shaped base, on which the first track 520 and the X-axis lead screw motor 530 are fixedly mounted. The X-axis lead screw motor 530 is threadedly connected to the first sliding component 540. When the X-axis lead screw motor 530 rotates, it drives the first sliding component 540 to move linearly along the first track 520. The Z-axis lead screw motor 560 is threadedly connected to the second sliding component 570. When the Z-axis lead screw motor 560 rotates, it drives the second sliding component 570 to move linearly along the second track 550. The Y-axis lead screw motor 581 is threadedly connected to the third sliding component 590. When the Y-axis lead screw motor 581 rotates, it drives the third sliding component 590 to move linearly along the third track 580. Therefore, the image acquisition component 600 on the third sliding component 590 can move along the X, Y, and Z axes. In this embodiment, the movement of the third sliding component 590 in the Z-axis direction is mainly used to adjust the focal length of the camera. By combining the movements in the X, Y, and Z axes, the movement range of the camera can be more easily controlled. The camera can be controlled to move to any position within the usable range, and the movement accuracy can be maintained within 0.01mm.

[0123] In some embodiments, the motion mechanism further includes sensing devices for sensing the movement positions of the first sliding component 540, the second sliding component 570, and the third sliding component 590, respectively. The sensing devices may include an optocoupler sensor and an optocoupler sensing sheet.

[0124] In some embodiments, the X-axis optical coupler sensor is fixedly disposed relative to the base, and the X-axis optical coupler sensing plate is fixedly disposed relative to the first sliding component 540. Together, they can sense the reset origin of the first sliding component 540 in the X-axis direction. The Z-axis optical coupler sensor is fixedly disposed relative to the second guide rail 550, and the Z-axis optical coupler sensing plate is fixedly disposed relative to the second sliding component 570. Together, they can sense the reset origin of the second sliding component 570 in the Z-axis direction. The Y-axis optical coupler sensor is fixedly disposed relative to the third guide rail 580, and the Y-axis optical coupler sensing plate is fixedly disposed relative to the third sliding component 590. Together, they can sense the reset origin of the third sliding component 590 in the Y-axis direction. In one implementation, the optical coupler sensor can be a PM-L25 optical coupler sensor, but is not limited to this. In some embodiments, limit blocks are respectively provided on the first track 520, the second track 550, and the third track 580 to prevent their respective cooperating sliding components from falling off during movement. In some embodiments, a control board mounting plate 511 for mounting the control board and a protective cover 512 for protecting the control board are also included, with the control board mounting plate 511 and the protective cover 512 mounted on one side of the support portion 510.

[0125] The above describes the oscillation device provided in this application. Accordingly, this application also provides an experimental apparatus, including an oscillation device mounted on a mounting platform.

[0126] In some embodiments, a vibration damping mechanism is provided between the oscillating device and the mounting platform. This mechanism can be, for example, a rubber shock absorber 114. The vibration damping mechanism can be fixedly mounted relative to the base plate 110, for example, it can be fixedly installed at the bottom of the base plate 110. The vibration damping mechanism can support the mounting platform and can reduce the vibration generated during the operation of the oscillating device, ensuring that it does not affect the normal operation of other equipment. In one implementation, the vibration damping mechanism can be a rubber shock absorber, but it is not limited to this; for example, it can also be a spring shock absorber.
