Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0019] Example 1 See Figures 1-3This embodiment provides a steerable transport device, including a first slider 1, a first transmission mechanism 2, a first base plate 3, a slice box fixing assembly 4, and a limiting assembly 5. One end of the first slider 1 is mounted on the first transmission mechanism 2, and the other end of the first slider 1 is slidably connected to a first slide rail 31 on the first base plate 3. The first transmission mechanism 2 drives the first slider 1 to slide along the first slide rail 31. The slice box fixing assembly 4 is fixed to the portion of the first slider 1 located on the first slide rail 31. The limiting assembly 5 is located on one side of the first base plate 3 in the length direction, and the limiting assembly 5 triggers the slice box fixing assembly 4 to rotate and turn so that the opening of the slice box 6 faces the slice taking station. For example, the first transmission mechanism 2 includes a stepper motor, a synchronous belt, and a reducer. The stepper motor is connected to the synchronous belt through the reducer. The first slider 1 is connected to the synchronous belt. The movement of the stepper motor drives the synchronous belt to move, and the movement of the synchronous belt in turn drives the first slider 1 to move, ultimately realizing that the first slider 1 drives the slice box fixing assembly 4 to move along the first slide rail 31.

[0020] The slice box fixing assembly 4 can be rotated so that the slices in the slice box 6 are facing the next slice picking station, which facilitates slice picking and improves work efficiency. The component that triggers the rotation of the slice box fixing assembly 4 is the limiting assembly 5.

[0021] See Figure 3 In the specific implementation process, the slicing box fixing assembly 4 includes a connecting base plate 41, a rotating plate 42, an angle deflection plate 43, a fixed base plate 44, and a first guide shaft 45 arranged sequentially from bottom to top; the lower part of the connecting base plate 41 is fixed to the upper part of the first slider 1; the connecting base plate 41 is connected to the rotating plate 42 through a rotating shaft 47, and the rotating plate 42 is triggered to rotate around the rotating shaft 47 by the limiting assembly 5; the rotating plate 42 is installed on the angle deflection plate 43, the fixed base plate 44 is slidably connected to the first guide shaft 45, and the bottom end of the first guide shaft 45 is fixed to the angle deflection plate 43; the longitudinal section structure of the first guide shaft 45 is n-shaped, and the n-shape and the fixed base plate 44 form a space for placing the slicing box 6, and the rotation of the rotating plate 42 drives the slicing box 6 to rotate and turn.

[0022] It should be noted that the rotating shaft 47 is fitted with a bearing 46, and the bearing 46 is located inside the connecting base plate 41.

[0023] It should be noted that an elastic element 48 is installed between the rotating plate 42 and the angle deflection plate 43. The elastic element 48 maintains a 5° angle between the rotating plate 42 and the angle deflection plate 43 (e.g., the rotating plate 42 is horizontally positioned, and the angle deflection plate 43 is tilted relative to the rotating plate 42), so that the slide box 6 is tilted, thereby reducing the centrifugal force during rotation and preventing the pathological slides from being thrown out. The outer edge of the rotating plate 42 is provided with a vertical protrusion 421, which is connected to the angle deflection plate 43 through a bearing shaft 49, allowing for fine adjustment of the rotation angle of the slide box 6.

[0024] It should be noted that the bottom end of the elastic element 48 is fixed in the corresponding hole on the rotating plate 42 (not labeled in the figure).

[0025] For example, the fixed base plate 44 is provided with a boss 441 for supporting the slice box 6 and located in the middle of the first guide shaft 45. The lower part of the first guide shaft 45 is fitted with a first bushing 451, which is connected to the fixed base plate 44. That is, the longitudinal section of the first bushing 451 is T-shaped. During use, the horizontal side of the T-shape is located on the upper surface of the fixed base plate 44, and the vertical side of the T-shape is inserted into the corresponding hole on the fixed base plate 44.

[0026] For example, both the upper end face of the connecting base plate 41 and the lower end face of the rotating plate 42 are provided with limiting members 411, so that when the rotating plate 42 rotates relative to the connecting base plate 41, the rotation angle of the rotating plate 42 can be controlled. More specifically, there are two limiting members 411 on the connecting base plate 41, arranged in a straight line on both sides of the bearing 46; there are also two limiting members 411 on the rotating plate 42, spaced at 90-degree angles, so that when one of the limiting members 411 on the rotating plate 42 abuts against one of the limiting members 411 on the connecting base plate 41 during the rotation of the rotating plate 42, the rotating plate 42 stops rotating. At this time, as needed, when the rotating plate 42 rotates in the opposite direction, the other limiting member 411 on the rotating plate 42 abuts against the other limiting member 411 on the connecting base plate 41 to prevent the rotating plate 42 from continuing to rotate. For example, the limiting member 411 can be a strip-shaped structure. For example, a position sensor is provided along the length of the first slide rail 31 to monitor the position information of the first slider 1 in real time, ensuring that the start and stop positions of the first slider 1 are accurate.

[0027] Furthermore, to prevent the slicing box 6 from shaking or falling during movement and rotation, a clamping mechanism 7 is provided on the fixed base plate 44. This structure clamps the slicing box 6, securing it during transportation. For example, the clamping mechanism 7 consists of two clamping blocks symmetrically arranged on both sides of the fixed base plate 44. That is, on the fixed base plate 44, the clamping blocks are arranged parallel to the first guide shaft 45, such that one clamping block corresponds to one shaft of the first guide shaft 45, allowing the portion of the slicing box 6 extending beyond the first guide shaft 45 to be clamped by the clamping blocks. See also... Figure 1 , Figure 2 In the specific implementation process, the limiting component 5 includes a fixed base 51, a roller plunger 52, and a cam follower 53. The fixed base 51 is fixed on the first base plate 3. The roller plunger 52 and the cam follower 53 are both installed on the fixed base 51. The slice box fixing component 4 is limited by the roller plunger 52 after being turned by the cam follower 53. At least two limiting components 5 are provided on the first base plate 3 to correspond to different functional units. For example, one limiting component 5 is positioned opposite to the clamping unit (the device for clamping the slice box 6), and another limiting component 5 is positioned opposite to the lifting component (the device for lifting the slice box fixing component). This allows the slice box to be transported to the transport device of this utility model by the clamping unit, then turned, and then lifted by the lifting component to the corresponding height of the next station (such as the scanning unit) for subsequent scanning work.

[0028] For example, four limiting components 5 are provided on one side of the first base plate 3, two of which are spaced apart and located in the middle of the first base plate 3, and the other two limiting components 5 are located at both ends of the length direction of the first base plate 3. At this time, an angle pressure plate is provided on the limiting component 5 at the end of the first base plate 3 to cooperate with the cam follower 53 provided on the angle deflection plate 43 to control the angle of the angle deflection plate 43. To improve accuracy, angle pressure plates 8 are provided on both sides of the width direction of the first base plate 3, so that at the same end of the length direction of the first base plate 3, two angle pressure plates 8 are used simultaneously to press the cam follower 53 on the angle deflection plate 43, causing the elastic element 48 to undergo elastic deformation and be compressed. At the same time, due to the action of the bearing shaft 49, the angle deflection plate 43 rotates relative to the rotating plate 42, so that the slices in the slice box 6 are horizontally positioned, making it convenient to remove the slices during subsequent operations.

[0029] See Figure 4 , Figure 5In a specific implementation, the transport device further includes a lifting component 9, which is located at the end of the first base plate 3 and is used to lift the slice box fixing component 4, after rotation and turning, to the slice removal height. For example, when a slice needs to be removed from the slice box 6 for scanning, since the slice box 6 contains several slices along its height direction, they need to be scanned one by one. Therefore, after each slice is removed from the slice box 6, the lifting component 9 is used to lift the slice box fixing component 4 to a suitable height before removing the slice from the slice box 6.

[0030] Further, the lifting assembly 9 includes a drive component 91, a bracket 92, a ball screw 93, a first connecting plate 94, and a lifting plate 95; the drive component 91 is disposed inside the bracket 92, and the output shaft of the drive component 91 is connected to the ball screw 93 through a coupling 96; the upper part of the ball screw 93 is connected to the first connecting plate 94 through a second bushing 97, and the lifting plate 95 is fixedly installed on the first connecting plate 94. The ball screw 93 controls the up and down movement of the first connecting plate 94, thereby driving the lifting plate 95 to move the slice box fixing assembly 4.

[0031] For example, the drive component 91 is a motor; the bracket 92 is a cuboid structure with an opening on one side for placing and removing the drive component 91. The upper part of the bracket 92 has an opening for mounting a bearing mounting seat 98, allowing the lower part of the ball screw 93 to pass through the bearing mounting seat 98 and enter the bracket 92. A sensor mounting seat 99 is fitted onto the ball screw 93 for mounting a sensor; more specifically, the sensor mounting seat 99 is located below the bearing mounting seat 98.

[0032] It should be noted that the lifting assembly 9 also includes a second guide shaft 991, a top plate 992, and a bearing support seat 993; the bottom end of the second guide shaft 991 extends into the through hole at the top of the second bracket 372, and the upper part of the second guide shaft 991 passes through the first connecting plate 94 and extends into the top plate 992. The bearing support seat 993 is installed on the upper part of the top plate 992, so that the top end of the ball screw 93 is installed on the bearing support seat 993. When the ball screw 93 is working, it drives the second guide shaft 991 and the first connecting plate 94 to move along the length direction of the ball screw 93.

[0033] It should be noted that the second guide shaft 991 is connected to the first connecting plate 94 via a sleeve (not labeled in the figure).

[0034] It should be noted that the lifting plate 95 has an L-shaped cross-section. The upper part of the long side of the L-shape is fixed to the first connecting plate 94. The horizontal side of the L-shape is opposite to the fixed base plate 44 and is located at the lower part of the outer edge of the fixed base plate 44. The fixed base plate 44 is lifted and moved up and down by the horizontal side of the L-shape, thereby realizing the up and down movement of the slice box 6.

[0035] This embodiment is implemented as follows: 1. The first transmission mechanism 2 operates to drive the slice box fixing assembly 4 to move towards the center of the first base plate 3. When the slice box fixing assembly 4 is rotated by the cam follower 53 (during this process, the rotating plate 42 rotates around the rotating shaft 47, and due to the setting of the limiting member 411, the rotation angle can only be 90 degrees), it is limited by the roller plunger 52. Then, it can be placed in the slice box fixing assembly 4 by other equipment (such as a feeding device). 2. Restart the first transmission mechanism 2 to move in the reverse direction. When the slice box fixing assembly 4 reaches the limiting assembly 5 at the end of the first base plate 3, it turns (at this time, the slice box 6 after rotating 90 degrees can face the direction of the next station, which is convenient for taking slices). After turning, the slice box fixing assembly 4 is pressed by the angle pressure plate 8. At this time, the angle pressure plate 8 presses on the side of the angle deflection plate 43 where the elastic element 48 is provided. The elastic element 48 is deformed and compressed under pressure, so that the angle deflection plate 43 is placed horizontally on the rotating plate 42.

[0036] The fixed base plate 44 is then lifted to a suitable height by the lifting plate 95 on the lifting assembly 9 (during this process, the fixed base plate 44 slides along the height direction of the first guide shaft 45), facilitating the removal of slices from the slice box 6 to the next station. For example, the slices are transported to the next station to prepare for subsequent slice scanning.

[0037] 3. After all slices in the slice collection box have been scanned, the first transmission mechanism 2 operates to move the slice collection box fixing assembly 4 toward the center of the first base plate 3 (i.e., to the slice collection box position in step 1), so that the slice collection box can be removed from the slice collection box fixing assembly 4 by a clamp.

[0038] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0039] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
