Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0067] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "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. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0068] Currently, in the process of sample storage and retrieval, the cryopreservation boxes containing the samples are generally transported by belt conveyors. However, belt conveyors require a large installation space, especially when long-distance transportation is required. In addition, belt conveyors are designed in a fixed manner, making it difficult to adjust the transportation distance according to different working conditions.

[0069] To address the aforementioned technical problems, this application provides a sliding table-type sample transport device. Through a multi-stage extendable sliding table mechanism, the transport process of the sample cryopreservation box can be optimized, especially in situations where space is limited or where flexible adjustment of the transport distance is required.

[0070] In some embodiments, refer to Figure 1 and Figure 2As shown, this application provides a sample conveying device, including: a slide mechanism 1 and a support mechanism 2. The slide mechanism 1 includes a base 101 and n-stage slides stacked sequentially on the base 101. The first-stage slide 102 is retractable relative to the base 101 along a first direction X, and the nth-stage slide 103 is retractable relative to the (n-1)th-stage slide along the first direction X, where n>1 and is an integer. The support mechanism 2 is disposed on the nth-stage slide 103 and is used to support a cryopreservation box 3.

[0071] Specifically, the core of the device is a multi-stage slide mechanism, comprising a base 101 and several layers (n stages) of sequentially stacked slides, namely, the first-stage slide 102 to the nth-stage slide 103. Each stage of the slide can extend and retract relative to its underlying platform along the same first direction X, where X can be the length direction of the entire device. This design allows the entire device to extend when needed to accommodate different conveying distance requirements and to retract when not in use to reduce space occupation. This multi-stage slide design provides the conveying device with high flexibility, as its length can be adjusted according to actual needs.

[0072] The support mechanism 2 is located on the top slide, i.e. the nth slide 103, and is responsible for supporting and positioning the cryopreservation box 3, ensuring that the cryopreservation box 3 remains stable throughout the transportation process and will not shift or fall due to the movement of the slide.

[0073] When it is necessary to transport the cryopreservation box 3, the extension length of each slide can be adjusted manually or automatically according to the required transport distance. For example, the automatic control system may include a controller and a drive mechanism, with the controller controlling the drive mechanism to drive the telescopic movement of each slide.

[0074] By precisely controlling the extension and retraction of each slide, the conveying distance can be finely adjusted, making sample delivery more accurate. After completing the conveying task, each slide can be retracted onto the base 101, thereby minimizing the overall size of the equipment to save space.

[0075] Therefore, this application provides a compact, flexible, and adjustable sample transport device, particularly suitable for sample management in environments such as laboratories and cold storage rooms, especially in places with limited space or where frequent changes in transport routes are required. Compared to traditional belt conveyors, this sliding table type transport device not only reduces the required installation space but also increases the flexibility and adaptability of the layout.

[0076] In some embodiments, refer to Figures 1 to 4As shown, the supporting mechanism 2 includes a tray 201 and a cryogenic box bracket 202. The tray 201 is mounted on the nth slide table 103. The tray 201 has a positioning groove 204 with an opening 203 on one side. The cryogenic box bracket 202 can slide into or out of the positioning groove 204 through the opening 203. The cryogenic box bracket 202 has multiple supporting positions 205 for supporting the cryogenic box 3.

[0077] Specifically, tray 201 is fixedly mounted on the topmost slide, serving as a basic component of the load-bearing mechanism 2. For example, refer to... Figure 3 The tray 201 has a rectangular structure and an opening 203 on one side in the width direction Z. This design allows the cryopreservation box holder 202 to be smoothly pushed in or pulled out in the horizontal direction (such as the length direction Y of the tray 201), which is convenient for operators or robots to load and unload samples, simplifies the operation process, and eliminates the need for complicated loading and unloading steps.

[0078] The cryopreservation box holder 202 is a component for directly placing cryopreservation boxes 3. It has multiple support positions 205, which can hold multiple cryopreservation boxes 3 at the same time. This design not only improves the efficiency of a single transport and reduces the number of transports, but also reduces the error rate during processing by centrally managing the cryopreservation boxes 3.

[0079] Before transport, a robotic arm can place the cryopreservation boxes 3 containing the samples into the respective support positions 205 of the cryopreservation box holder 202. Then, the cryopreservation box holder 202 is horizontally pushed into the tray 201 through the opening 203 of the positioning slot 204, ensuring it is securely in place. When the slide mechanism 1 extends, the cryopreservation box holder 202, along with the cryopreservation boxes 3 on it, is transported to the designated position. After reaching the designated position, the slide mechanism 1 retracts, at which point the cryopreservation box holder 202 can be removed from the tray 201 in the same manner, completing the sample transport task.

[0080] Therefore, the carrier mechanism 2 provided in this application embodiment can improve the transportation efficiency and stability and reliability of the cryopreservation box 3.

[0081] In some embodiments, refer to Figure 2 and Figure 3 As shown, the positioning groove 204 has rotatable rollers 206 on the opposite side walls in the direction perpendicular to the sliding direction of the cryopreservation box bracket 202. The rollers 206 are used to support the side of the cryopreservation box bracket 202.

[0082] Specifically, the sliding direction of the cryopreservation box holder 202 can be the length direction Y of the tray 201, and the vertical direction of the sliding direction is the width direction Z of the tray 201. By setting rotatable rollers 206 on both sides of the positioning groove 204 in the width direction Z, the friction between the cryopreservation box holder 202 and the tray 201 can be significantly reduced, making it easier for the cryopreservation box holder 202 to be pushed in or pulled out, thus improving work efficiency.

[0083] Understandably, the rollers 206 not only support the sides of the cryopreservation box holder 202, but also serve as limit guides, ensuring that the cryopreservation box holder 202 moves accurately along the sliding path. This design improves the positional accuracy of the cryopreservation box holder 202, preventing it from shifting or tilting during sliding, thereby ensuring the safety of the samples.

[0084] Therefore, by setting rollers 206 on both sides of the positioning groove 204, the present application embodiment effectively solves the problems of high friction and instability in the traditional sliding method, and enhances the ease of operation and reliability of the sample conveying device.

[0085] In some embodiments, refer to Figure 1 and Figure 2 As shown, the sample conveying device also includes a drive mechanism 4, which includes a driver 401 and an n-stage transmission pair. The driver 401 is mounted on the base 101. The first-stage slide 102 is connected to the base 101 via the first-stage transmission pair 402, and the n-stage slide 103 is connected to the (n-1)-th stage slide via the n-th stage transmission pair 403. The driver 401 is used to drive the n-stage transmission pair to move the n-stage slide telescopically.

[0086] Specifically, the driver 401 is the driving source for the entire drive mechanism 4. Depending on different design requirements, the driver 401 may include a single motor or multiple motors.

[0087] The n-stage transmission pair includes the first-stage transmission pair 402 to the nth-stage transmission pair 403, and from the second-stage slide to the nth-stage slide 103, each stage slide is connected to the next stage slide through a corresponding transmission pair. Each stage transmission pair is responsible for transmitting the power generated by the driver 401 to each stage slide, enabling them to perform telescopic movements according to a predetermined first direction X and distance.

[0088] In one example, a multi-motor drive can be used, where each slide stage corresponds to an independent motor. This design allows each slide stage to operate independently, providing greater flexibility and precision. For example, in some cases, it may be necessary for some slide stages to move while others remain stationary; or different slide stages may need to move at different speeds.

[0089] In another example, a single-motor drive can be used, where all slides are driven by the same motor, with power distribution achieved through n-stage transmission pairs. This approach simplifies the electrical control structure and reduces costs.

[0090] Therefore, by integrating the drive mechanism 4, the sample conveying device in this application embodiment not only achieves automated conveying but also provides high flexibility and accuracy, making it suitable for various complex working environments and application scenarios.

[0091] In some embodiments, refer to Figure 2 and Figure 5 As shown, the first-stage transmission pair 402 includes a first-stage transmission assembly 404, which includes a first-stage driving wheel 405, a first-stage driven wheel 406, a first-stage transmission component 407, and a first-stage positioning component 408. The first-stage driving wheel 405 is connected to the output end of the driver 401. The first-stage driven wheel 406 is rotatably disposed on the end of the base 101 away from the first-stage driving wheel 405. The first-stage transmission component 407 is wound around the first-stage driving wheel 405 and the first-stage driven wheel 406. The first-stage positioning component 408 is fixed on the first-stage transmission component 407 and fixedly connected to the first-stage slide table 102.

[0092] Specifically, the driver (such as a motor) is mounted on the left end of the base 101, and the first-stage drive wheel 405 is mounted on the output end of the driver 401, responsible for receiving power from the driver 401. The first-stage drive wheel 405 can be a sprocket or a roller, the specific choice depending on the application requirements. The first-stage driven wheel 406 is mounted on the right end of the base 101 away from the first-stage drive wheel 405, and is used in conjunction with the first-stage drive wheel 405. The first-stage driven wheel 406 can also be a sprocket or a roller, and can rotate on the base 101.

[0093] The first-stage transmission component 407 is wound between the first-stage driving wheel 405 and the first-stage driven wheel 406, serving as a medium for power transmission. Depending on the selection of the first-stage driving wheel 405 and the first-stage driven wheel 406, the first-stage transmission component 407 can be a chain or a belt. The first-stage positioning component 408 is fixed to the first-stage transmission component 407 and is fixedly connected to the first-stage slide 102. The function of the first-stage positioning component 408 is to drive the first-stage slide 102 to move together when the first-stage transmission component 407 moves, ensuring the accurate extension and retraction of the first-stage slide 102.

[0094] When the driver (motor) rotates, it drives the first-stage driving wheel 405 to rotate through its output end. The rotation of the first-stage driving wheel 405 causes the first-stage transmission member 407 wound around it to move accordingly. The movement of the first-stage transmission member 407 simultaneously drives the first-stage driven wheel 406 to rotate, and the entire process forms a transmission system. The linear movement of the first-stage transmission member 407 is converted into the extension and retraction of the first-stage slide 102 through the first-stage positioning member 408. It can be understood that the fixed connection between the first-stage positioning member 408 and the first-stage slide 102 ensures that the first-stage slide 102 can extend and retract synchronously with the movement of the first-stage transmission member 407. Furthermore, by controlling the forward and reverse rotation of the motor, the bidirectional movement of the first-stage slide 102, i.e., extension and retraction, can be achieved.

[0095] Therefore, the embodiments of this application can realize automated, precise and reliable movement of the first-stage slide 102, thereby improving the overall movement performance of the sample transport device.

[0096] In some embodiments, refer to Figure 2 and Figure 5 As shown, the first-stage transmission pair 402 also includes a first-stage guide assembly 409, which is connected between the first-stage slide 102 and the base 101.

[0097] Specifically, the first-stage guide assembly 409 may include a first-stage slide rail 410 and a first-stage slider 411 that cooperate with each other. The first-stage slide rail 410 is fixed on the base 101 along the first direction X, and the first-stage slider 411 is connected to the bottom of the first-stage slide table 102.

[0098] The embodiments of this application provide a stable guiding function through the first-stage guide component 409, which keeps the first-stage slide 102 linear during movement, avoids deviation or tilting, and thus improves movement stability.

[0099] In some embodiments, refer to Figure 2 and Figure 5 As shown, the first-stage transmission pair 402 also includes a first-stage support assembly 412, which is located at one end of the base 101 near the first-stage driven wheel 406 and is used to support the first-stage slide 102.

[0100] Specifically, the first-stage support component 412 can be a support arm, roller support, or other form of mechanical support structure, and the specific choice can depend on the application requirements and load conditions.

[0101] Understandably, when the first-stage slide 102 is fully extended, its end is prone to sag due to its own weight or the support of other components. The first-stage support assembly 412 can effectively share this weight, keeping the first-stage slide 102 horizontal. By supporting the first-stage slide 102, the torque exerted by the first-stage slide 102 on the first-stage slider 411 is reduced, preventing the first-stage slider 411 from bearing excessive lateral pressure, thereby protecting the first-stage guide assembly 409. Similarly, when the first-stage slide 102 is retracted, the first-stage support assembly 412 can also support the first-stage slide 102, reducing the torque exerted by the first-stage slide 102 on the first-stage slider 411, thereby extending its service life.

[0102] Therefore, the embodiments of this application not only enhance the stability and accuracy of the movement of the first-stage slide 102, but also extend the service life of the equipment by reducing the load on the components.

[0103] In some embodiments, refer to Figure 5 As shown, the first-stage support assembly 412 includes a first-stage bracket 413 and a first-stage support wheel 414. The first-stage bracket 413 is located at one end of the base 101 adjacent to the first-stage driven wheel 406; the first-stage support wheel 414 is rotatably mounted on the first-stage bracket 413.

[0104] Specifically, the first-stage bracket 413 serves as the fixed base for the first-stage support wheel 414. The first-stage support wheel 414 is rotatably mounted on the first-stage bracket 413, contacting and providing support to the first-stage slide table 102. This effectively distributes the weight of the first-stage slide table 102, reduces the torque exerted by the first-stage slide table 102 on the first-stage slider 411, and also reduces the frictional resistance between the first-stage slide table 102 and the first-stage slide table 102, making the movement of the first-stage slide table 102 smoother, thereby improving the response speed and operating accuracy of the device.

[0105] Therefore, by introducing a rotatable first-stage support wheel 414, the first-stage support assembly 412 not only effectively supports the first-stage slide 102, but also improves the mobility of the device by reducing friction.

[0106] The n-stage transmission pair of the drive mechanism 4 of the sample conveying device provided in the embodiments of this application will be described below.

[0107] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6As shown, the nth-stage transmission pair 403 includes an nth-stage transmission assembly 415, which includes an nth-stage driving wheel 416, an nth-stage driven wheel 417, an nth-stage transmission member 418, and an nth-stage positioning member 419. The nth-stage driving wheel 416 is rotatably disposed at one end of the (n-1)th-stage slide adjacent to the driver 401, and the nth-stage driven wheel 417 is rotatably disposed at one end of the (n-1)th-stage slide away from the nth-stage driving wheel 416. The nth-stage transmission member 418 is wound around the nth-stage driving wheel 416 and the nth-stage driven wheel 417. The nth-stage positioning member 419 includes a first positioning member 420 and a second positioning member 421.

[0108] When n=2, the first positioning member 420 of the second-stage positioning member is fixed to one end of the base 101 near the first-stage driven wheel 406 and is fixedly connected to one side of the second-stage transmission member, and the second positioning member 421 is fixed to the other side of the second-stage transmission member and is fixedly connected to the second-stage slide.

[0109] When n>2, the first positioning member 420 of the nth-level positioning member 419 is fixed to one end of the (n-2)th-level slide adjacent to the (n-1)th-level driven wheel and is fixedly connected to one side of the nth-level transmission member 418, and the second positioning member 421 is fixed to the other side of the nth-level transmission member 418 and is fixedly connected to the nth-level slide 103.

[0110] Specifically, the nth-stage driving wheel 416 and the nth-stage driven wheel 417 are mounted on both ends of the side of the (n-1)th-stage slide. The nth-stage driving wheel 416 and the nth-stage driven wheel 417 can be sprockets or rollers, depending on the application requirements. The nth-stage transmission component 418 is wound between the nth-stage driving wheel 416 and the nth-stage driven wheel 417, serving as a medium for power transmission. Depending on the selection of the nth-stage driving wheel 416 and the nth-stage driven wheel 417, the nth-stage transmission component 418 can be a chain or a belt. The nth-stage positioning components 419 all include a first positioning component 420 and a second positioning component 421, used to fix the nth-stage transmission component 418 to a specific position and connect it to the nth-stage slide 103.

[0111] When n=2, this is a two-stage telescopic slide mechanism. When it is necessary to unfold and transport samples, after the driver (motor) is started, it first drives the first-stage slide 102 to extend forward through the first-stage transmission pair 402 (see the previous description for details, which will not be repeated here). At the same time, the movement of the first-stage slide 102 also drives the second-stage driving wheel, the second-stage driven wheel, and the second-stage transmission component mounted on it to move forward. At this time, since one side of the second-stage transmission component is fixed to the base 101 through the first positioning member 420, when the first-stage slide 102 extends forward, the second-stage driving wheel and the second-stage driven wheel will roll forward on the second-stage transmission component. This rolling motion causes the other side of the second-stage transmission component to move forward as well, and then drives the second-stage slide to extend forward together through the second positioning member 421. Conversely, when it is necessary to retract, the driver 401 reverses, causing the first-stage slide 102 to retract backward. During this process, the second-stage transmission component and the second-stage slide will also move backward synchronously, eventually returning to the base 101.

[0112] When n>2, this is a multi-stage telescopic slide mechanism, where the movement of each stage of the slide will sequentially drive the corresponding components of the next stage to move in the same direction. The working principle is explained below using a three-stage telescopic slide mechanism (n=3) as an example:

[0113] When it is necessary to unfold and transport the sample, after the driver (motor) is started, it first drives the first-stage slide 102 to extend forward through the first-stage transmission pair 402 (see the previous description for details, which will not be repeated here). At the same time, the movement of the first-stage slide 102 also drives the second-stage driving wheel, the second-stage driven wheel, and the second-stage transmission component mounted on it to move forward. At this time, since one side of the second-stage transmission component is fixed to the base 101 through the first positioning member 420, when the first-stage slide 102 extends forward, the second-stage driving wheel and the second-stage driven wheel will roll forward on the second-stage transmission component. This rolling motion causes the other side of the second-stage transmission component to move forward as well, which in turn drives the second-stage slide to extend forward together through the second positioning member 421.

[0114] Simultaneously, the movement of the second-stage slide also drives the third-stage driving wheel, the third-stage driven wheel, and the third-stage transmission component mounted on it to move forward. Since one side of the third-stage transmission component is fixed to the first-stage slide 102 via the first positioning element 420, when the second-stage slide extends forward, the third-stage driving wheel and the third-stage driven wheel will roll forward on the third-stage transmission component. This rolling motion causes the other side of the third-stage transmission component to move forward as well, thereby driving the third-stage slide to extend forward together via the second positioning element 421.

[0115] Conversely, when retraction is required, the driver 401 reverses, causing the first-stage slide 102 to retract backward. During this process, the second-stage transmission component, the second-stage slide, the third-stage transmission component, and the third-stage slide will also move backward synchronously, eventually returning to the base 101.

[0116] When n>3, the working principle of the multi-stage sliding mechanism is the same as above, and will not be repeated here.

[0117] Therefore, through the above-described transmission design, the embodiments of this application can achieve automatic extension and retraction of multi-stage slides with only one drive source, reducing the complexity of the device and lowering the cost. Furthermore, all slides can maintain good synchronous movement, ensuring the accuracy and stability of the sample transport process.

[0118] In some embodiments, refer to Figure 2 and Figure 6 As shown, the nth stage transmission pair 403 also includes an nth stage guide assembly 422, which is connected between the nth stage slide 103 and the (n-1)th stage slide.

[0119] Specifically, the nth-level guide assembly 422 may include an nth-level slide rail 423 and an nth-level slider 424 that cooperate with each other. The nth-level slide rail 423 is fixed to the (n-1)th-level slide table along the first direction X, and the nth-level slider 424 is connected to the bottom of the nth-level slide table 103.

[0120] The embodiments of this application provide a stable guiding function through the nth-level guide component 422, which enables the nth-level slide 103 to maintain linearity during movement, avoiding deviation or tilting, thereby improving movement stability.

[0121] In some embodiments, refer to Figure 2 and Figure 6 As shown, the nth stage transmission pair 403 also includes an nth stage support assembly 425, which is located at one end of the (n-1)th stage slide adjacent to the nth stage driven wheel 417 and is used to support the nth stage slide 103.

[0122] Specifically, the nth-level support component 425 can be a support arm, roller support, or other form of mechanical support structure, the specific choice of which may depend on application requirements and load conditions.

[0123] Understandably, when the nth-stage slide 103 is fully extended, its end is prone to sag due to its own weight or the support of other components. The nth-stage support assembly 425 effectively shares this weight, keeping the nth-stage slide 103 level. By supporting the nth-stage slide 103, the torque exerted by the nth-stage slide 103 on the nth-stage slider 424 is reduced, preventing the nth-stage slider 424 from bearing excessive lateral pressure, thereby protecting the nth-stage guide assembly 422. Similarly, when the nth-stage slide 103 is retracted, the nth-stage support assembly 425 can also support the nth-stage slide 103, reducing the torque exerted by the nth-stage slide 103 on the nth-stage slider 424, thereby extending its service life.

[0124] Therefore, the embodiments of this application not only enhance the stability and accuracy of the movement of the nth stage slide 103, but also extend the service life of the equipment by reducing the load on the components.

[0125] In some embodiments, refer to Figure 6 As shown, the nth-level support assembly 425 includes an nth-level bracket 426 and an nth-level support wheel 427. The nth-level bracket 426 is located at one end of the (n-1)th-level slide adjacent to the nth-level driven wheel 417. The nth-level support wheel 427 is rotatably mounted on the nth-level bracket 426.

[0126] Specifically, the nth-level bracket 426 serves as the fixed base for the nth-level support wheel 427. The nth-level support wheel 427 is rotatably mounted on the nth-level bracket 426, contacts the nth-level slide 103, and provides support. This effectively distributes the weight of the nth-level slide 103, reduces the torque exerted by the nth-level slide 103 on the nth-level slider 424, and also reduces the frictional resistance between the nth-level slide 103 and the nth-level slide 103, making the movement of the nth-level slide 103 smoother, thereby improving the response speed and operating accuracy of the device.

[0127] Therefore, by introducing a rotatable nth-level support wheel 427, the nth-level support assembly 425 not only achieves effective support for the nth-level slide 103, but also improves the mobility of the device by reducing friction.

[0128] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
