Description

Technical Field

[0001] This application relates to the field of digital pathology technology, and in particular to a slide retrieval auxiliary mechanism, a slide storage device, and a slide retrieval and ejection device. Background Technology

[0002] With the development of medical technology, digital pathology has gradually become an important means of pathological diagnosis. Digital slide scanners, as the core equipment of digital pathology, can convert traditional glass slides into high-resolution digital images, allowing pathologists to perform remote diagnosis and analysis on computers or mobile devices. This technology not only improves the convenience of diagnosis but also offers advantages such as permanent image storage, ease of management, and sharing. Furthermore, combined with internet and artificial intelligence technologies, digital slide scanners can enable 24-hour online remote consultations and assisted diagnosis, greatly improving the efficiency and accuracy of pathological diagnosis and alleviating the problems of pathologist shortages and uneven distribution.

[0003] Existing high-throughput digital slide scanners typically use grippers that extend directly into the slide basket in the slide compartment to hold the slides, then remove the slides from the compartment and deliver them to the scanning area for scanning. Because the gaps between adjacent slides in the basket are small, the grippers must be designed to be very thin, which leads to control difficulties and increases the risk of errors during slide handling, such as slide breakage or unstable gripping. Furthermore, this design increases the manufacturing cost of the grippers.

[0004] Therefore, there is an urgent need to provide a new solution to improve gripping efficiency, reduce the difficulty of gripping control, and at the same time avoid increasing the manufacturing cost of the grippers. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a film picking auxiliary mechanism, a film storage device, and a film picking and unloading device, which can improve the gripping efficiency, reduce the difficulty of gripping control, and avoid increasing the manufacturing cost of the grippers.

[0006] To achieve the above-mentioned technical objectives, this application provides a wafer-retrieving auxiliary mechanism, including a mechanism carrier, an ejector, and an ejection drive assembly;

[0007] The ejector is movably mounted on the mechanism carrier;

[0015] Furthermore, the ejection drive assembly includes an ejection motor and a cam;

[0016] The ejector motor is connected to the cam and is used to drive the cam to rotate and contact the ejector.

[0017] As the cam gradually comes into contact with the ejector during its lift phase, it can push the ejector to move in the direction of ejecting the slice.

[0018] Furthermore, a roller is rotatably mounted on the ejector;

[0019] The roller can make rolling contact with the cam.

[0020] Furthermore, it also includes detection components;

[0021] The detection component is used to detect whether the ejector has been reset in place.

[0022] Furthermore, the detection component includes a photoelectric sensor and a light-shielding sheet;

[0023] The photoelectric sensor is fixed to the mechanism carrier;

[0024] The light-shielding sheet is fixedly connected to the ejector.

[0025] When the ejector is in the reset state, the sensed portion of the light-shielding sheet is located in the sensing groove of the photoelectric sensor.

[0026] Furthermore, it also includes limiting components;

[0027] The limiting component is installed on the mechanism carrier and is used to limit the reset position of the ejector.

[0028] Furthermore, the limiting component includes a limiting fixing block and a limiting top member;

[0029] The limiting and fixing block is fixed to the mechanism carrier and is located on one side of the ejector.

[0030] A stop block is fixed on one side of the ejector;

[0031] The limiting top member moves through the limiting fixing block along the movement direction of the ejector member and is threadedly connected to the limiting fixing block;

[0032] The end of the limiting top piece that passes through the limiting fixing block can abut against the abutting block.

[0033] This application also discloses a film storage device, including a film storage body, a first displacement mechanism, and the aforementioned film retrieval auxiliary mechanism;

[0034] The slice container body contains multiple compartments for storing slices;

[0035] The front of the compartment has a film outlet, while the back has a film pusher.

[0036] The film-taking auxiliary mechanism is located on the side of the film-pushing port away from the film-dispensing port;

[0037] The first displacement mechanism is connected to the tablet compartment body or the tablet retrieval auxiliary mechanism, and is used to drive the tablet compartment body or the tablet retrieval auxiliary mechanism to move, so that the push-out component of the tablet retrieval auxiliary mechanism can correspond to different push-out positions.

[0038] Furthermore, the multiple compartments are spaced apart in the Z-axis direction;

[0039] The first displacement mechanism is connected to the disc storage body and is used to drive the disc storage body to move in the Z-axis direction.

[0040] This application also discloses a wafer ejection device, including a wafer ejection unit and the wafer storage unit;

[0041] The slide ejection device is located on one side of the slide compartment device and is used to transport the ejected slides to the microscopic scanning device.

[0042] Furthermore, the piece removal device includes a second displacement mechanism and grippers;

[0043] The grippers grasp and push out the slice in the thickness direction of the slice;

[0044] The second displacement mechanism is connected to the gripper and is used to drive the gripper to move.

[0045] Furthermore, it also includes a macroscopic image acquisition device;

[0046] The macroscopic image acquisition device is used to identify the label area and sample area on the slice before scanning;

[0047] The slide ejection device is used to transport the ejected slide to the microscopic scanning device and expose the sample area of ​​the slide to the scanning area of ​​the microscopic scanning device.

[0048] As can be seen from the above technical solutions, the core working principle of the meticulously designed slide-picking auxiliary mechanism in this application is to effectively drive the ejector component to move precisely in the target direction of the slide by cleverly utilizing the mechanical action of the ejection drive component. During this process, the slide to be scanned can be smoothly ejected from the slide chamber a precise distance, greatly facilitating the gripping operation of the grippers. This design successfully solves many problems existing in traditional slide-picking methods. In particular, due to the relatively small gap between adjacent slides, the gripper's jaws have to be designed to be extremely thin and fine. This not only poses a significant challenge to the precise operation of the control system but also significantly increases the risk of various errors during slide picking, such as slide breakage or insufficient gripping stability. More importantly, this requirement for the fine design of the grippers inevitably increases the manufacturing cost of the grippers, thus affecting the economic efficiency of the entire production process to some extent. The slide-picking auxiliary mechanism proposed in this application effectively alleviates these problems, thereby improving the overall operational efficiency and safety. Attached Figure Description

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0060] This application discloses a film retrieval auxiliary mechanism, a film storage device, and a film retrieval and ejection equipment.

[0061] Please see Figure 1 as well as Figure 3 One embodiment of a film-retrieving auxiliary mechanism provided in this application includes:

[0062] Mechanism carrier 1, ejector 2, and ejection drive assembly 3.

[0063] The ejector 2 is movably mounted on the mechanism carrier 1; the ejection drive assembly 3 is mounted on the mechanism carrier 1 and connected to the ejector 2, and is used to drive the ejector 2 to move in the direction of ejecting the slice 100.

[0064] The meticulously designed slide-picking auxiliary mechanism of this application works by cleverly utilizing the mechanical action of the push-out drive component 3 to effectively drive the push-out component 2 to move precisely in the target direction of pushing out the slide 100. During this process, the slide 100 to be scanned can be smoothly pushed out of the slide chamber a precise distance, greatly facilitating the gripping operation of the gripper 82. This design successfully solves many problems existing in traditional slide-picking methods. In particular, due to the relatively small gap between adjacent slides 100, the grippers of the gripper 82 have to be designed to be extremely thin and fine. This not only poses a significant challenge to the precise operation of the control system but also significantly increases the risk of various errors during the gripping of the slide 100, such as the slide 100 being prone to breakage or insufficient gripping stability. More importantly, this requirement for the fine design of the gripper inevitably increases the manufacturing cost of the gripper 82, affecting the economic efficiency of the entire production process to some extent. The slide-picking auxiliary mechanism proposed in this application effectively alleviates these problems, thereby improving the overall operational efficiency and safety.

[0065] The above is an embodiment of a film-retrieving auxiliary mechanism provided in this application. The following is an embodiment of a film-retrieving auxiliary mechanism provided in this application. Please refer to the following for details. Figures 1 to 3 .

[0066] Based on the solution of Embodiment 1 above:

[0067] Furthermore, such as Figure 1 As shown, a guide rail 23 is installed on the mechanism carrier 1; the push-out part 2 is slidably installed on the guide rail 23.

[0068] This improved design makes the movement of the ejector 2 smoother and more controllable. The introduction of the guide rail 23 not only improves the accuracy of the ejector 2's movement but also effectively reduces the shaking of the ejector 2 during movement, thereby further ensuring the safety and integrity of the slice 100 during the ejection process. In addition, the sliding installation method of the guide rail 23 facilitates the quick reset of the ejector 2, providing more convenience for subsequent slice removal operations.

[0069] The ejection drive assembly 3 may only have the function of driving the ejector 2 to move in the direction of ejecting the slice 100. In this case, there are at least two reset methods:

[0070] In the first method, the slice 100 drives the ejector 2 to reset. Specifically, after the slice 100 completes scanning, it is transported back to the slice magazine by the gripper 82. After the gripper 82 picks up the slice 100 and returns it to its original position, the slice 100 is still in the ejected state. The gripper 82 releases the slice 100 and gently pushes the slice 100 back to its initial position with its end. During this process, the slice 100 can also push the ejector 2 to reset.

[0071] The second method involves adding a reset component 6. Specifically, the reset component 6 is installed on the mechanism carrier 1 and connected to the ejector 2, used to drive the ejector 2 to reset. In this second reset method, the design of the reset component 6 further enhances the automation level of the slide-taking auxiliary mechanism. Through the precise control of the reset component 6, the ejector 2 can quickly and accurately reset after completing the slide ejection task 100, fully preparing for the next slide-taking operation. This design not only improves work efficiency but also effectively avoids slide-taking errors caused by the ejector 2 not resetting in a timely or proper manner.

[0072] Furthermore, such as Figure 2 As shown, the reset assembly 6 includes an elastic element 61; one end of the elastic element 61 is fixedly connected to the ejector 2, and the other end is fixedly connected to the mechanism carrier 1 or the guide rail 23. This design makes the structure of the reset assembly 6 simple and easy to implement. During the process of the ejector 2 ejecting the slice 100, the elastic element 61 is compressed or stretched to store energy, and when the ejector 2 needs to be reset, the elastic element 61 releases the stored energy, pushing the ejector 2 to reset quickly. This method of resetting using the elastic element 61 is not only low-cost, but also has a stable and reliable resetting effect, further improving the practicality and reliability of the slice removal auxiliary mechanism.

[0073] The elastic element 61 can be a tension spring. For easy fixing, the reset component 6 is provided with two fixing pins 62, one fixed to the side of the pusher and the other fixed to the side of the slide rail or fixed to the mechanism carrier 1.

[0074] Regarding the design of the mechanism carrier 1, it can be a plate structure design; regarding the push-out part 2, in order to meet the requirements of cooperating with the slide rail and pushing the slice 100, it can be designed to include a push rod part 22 and a slider part 21; the bottom of the slider part 21 is slidably connected to the guide rail 23, while the front end is fixedly connected to the push rod part 22, or it can be integrally formed, and there are no specific restrictions.

[0075] The drive assembly 3 can be designed in various ways, such as a telescopic cylinder assembly, an electric actuator assembly, and another assembly design disclosed below.

[0076] Specifically, the ejection drive assembly 3 includes an ejection motor 33 and a cam 31; the ejection motor 33 is connected to the cam 31 and is used to drive the cam 31 to rotate and contact the ejector 2.

[0077] As the cam 31 gradually comes into contact with the pusher 2 during its lift phase, it can push the pusher 2 to move in the direction of the pusher slice 100 (by using the contour of the lift phase of the cam 31 to push the rod out).

[0078] This design fully utilizes the motion characteristics of the cam 31 mechanism. Through precise control of the push-out motor 33 (such as a rotary servo), the cam 31 can rotate along a predetermined trajectory, thereby driving the push-out member 2 to perform a smooth and precise push-out motion. During the rotation of the cam 31, its lift segment gradually contacts the push-out member 2 and applies a thrust, enabling the push-out member 2 to smoothly push out the slice 100. This design not only improves the accuracy and stability of the push-out motion but also effectively avoids damage to the slice 100 or push-out errors caused by sudden changes in thrust. In addition, the introduction of the cam 31 mechanism makes the structure of the push-out drive assembly 3 more compact and efficient, providing more flexibility for the overall design of the slice-taking auxiliary mechanism.

[0079] The push-out drive assembly 3 also includes a fixed seat 32, which is fixed to the top of the mechanism carrier 1 and can be connected to a slide rail or integrally formed with the slide rail, and then fastened to the mechanism carrier 1 by screws or bolts; the mechanism carrier 1 is provided with a mounting through hole 11 at the position corresponding to the fixed seat 32. The push-out motor 33 can be designed to be in the mounting through hole 11 and fixed to the fixed seat 32 or the mechanism carrier 1. Then its drive shaft passes upward through the fixed seat 32 and is fixedly connected to the cam 31 to drive the cam 31 to rotate.

[0080] Furthermore, such as Figure 1 As shown, a roller 24 is rotatably mounted on the ejector 2, which can be specifically mounted on the slider 21. The roller 24 can roll contact with the cam 31. Taking the design of the elastic element 61 as an example, the elastic element 61 provides the elastic force for the ejector 2 to reset, so that the cam 31 maintains rolling contact with the roller 24 during the rotation.

[0081] During the process of the pusher 2 being pushed by the cam 31, the rolling contact between the roller 24 and the cam 31 effectively reduces frictional resistance, allowing the pusher 2 to move more smoothly along the predetermined trajectory. Furthermore, the design of the roller 24 helps reduce wear between the cam 31 and the pusher 2, thereby extending the service life of the wafer-picking auxiliary mechanism. To ensure stable rolling of the roller 24, a support structure such as a bearing or bushing can be installed at the mounting location of the roller 24 to improve its rotational flexibility and stability.

[0082] Furthermore, such as Figure 1 As shown, it also includes a detection component 4, which is used to detect whether the ejector 2 has been reset in place, so as to facilitate the next step. The introduction of the detection component 4 enables the system to monitor the reset status of the ejector 2 in real time. Once the ejector 2 is reset in place, the system can immediately proceed to the next operation, thereby greatly improving work efficiency.

[0083] Furthermore, the detection component 4 includes a photoelectric sensor 41 and a light-shielding plate 42; the photoelectric sensor 41 is fixed on the mechanism carrier 1; the light-shielding plate 42 is fixedly connected to the push-out component 2.

[0084] When the ejector 2 is in the reset state, the sensed portion 421 of the light shield 42 is located in the sensing groove 411 of the photoelectric sensor 41.

[0085] When the ejector 2 is pushed and moves along a predetermined trajectory to return to the reset state, the light-shielding plate 42 moves into the sensing slot 411 of the photoelectric sensor 41. The photoelectric sensor 41 can sensitively detect the presence of the light-shielding plate 42, thus confirming that the ejector 2 has been reset. This design ensures that the system can accurately determine the state of the ejector 2, avoiding operational errors or system malfunctions caused by the ejector 2 not being fully reset. At the same time, the combined use of the photoelectric sensor 41 and the light-shielding plate 42 also improves the automation level of the system, making the entire film-picking auxiliary mechanism more intelligent and efficient.

[0086] Furthermore, such as Figure 1 As shown, it also includes a limiting component 5; the limiting component 5 is installed on the mechanism carrier 1 and is used to limit the reset position of the ejector 2.

[0087] During the resetting process of the ejector 2, the limiting component 5 ensures that the ejector 2 accurately stops at the predetermined position, thereby avoiding operational errors caused by over- or under-resetting. This design not only improves the accuracy and stability of the wafer-picking auxiliary mechanism but also effectively extends its service life.

[0088] Furthermore, such as Figure 1 As shown, the limiting component 5 includes a limiting fixing block 51 and a limiting top member 52.

[0089] The limiting and fixing block 51 is fixed to the mechanism carrier 1 and located on one side of the ejector 2; an abutment block 25 is fixed on one side of the ejector 2 (specifically, an abutment block 25 may be fixed on one side of the slider part 21).

[0090] The limiting top member 52 moves along the direction of movement of the pusher 2 through the limiting fixing block 51 and is threadedly connected to the limiting fixing block 51 (specifically, a nut 53 can be embedded in the limiting fixing block 51, and the limiting top member 52 passes through the nut 53 and is threadedly connected to the nut 53). The limiting top member 52 can be a bolt or screw, and there is no specific limitation.

[0091] The limiting top piece 52 passes through one end of the limiting fixing block 51 and can abut against the abutting block 25.

[0092] When the ejector 2 returns to its predetermined position, the abutment block 25 makes tight contact with one end of the limiting top member 52, forming an effective limiting effect. This design allows the ejector 2 to be precisely guided and controlled during the reset process, ensuring that it accurately returns to its initial position after each operation. Furthermore, the threaded connection between the limiting top member 52 and the limiting fixing block 51 not only provides robust support but also allows the user to adjust the position of the limiting top member 52 according to actual needs, thereby achieving precise setting of the reset position of the ejector 2. This flexibility and adjustability further enhances the adaptability and practicality of the wafer-picking auxiliary mechanism.

[0093] Taking the design with abutment block 25 as an example, the light-shielding sheet 42 can be fixedly connected to the abutment block 25.

[0094] like Figure 3 As shown, this application also discloses a film storage device, including a film storage body 72, a first displacement mechanism 71, and a film retrieval auxiliary mechanism.

[0095] The slide compartment body 72 has multiple compartments for storing slides 100; the front of the compartment has a slide outlet, and the back has a slide pusher; it can be understood that the slides 100 can be extended from both ends of the compartment, so that the pusher 2 of the slide retrieval auxiliary mechanism can push the slides 100 from the slide pusher side toward the slide outlet, so that the slides 100 extend a certain distance from the slide outlet.

[0096] The film retrieval auxiliary mechanism is located on the side of the film pusher that is away from the film outlet.

[0097] The first displacement mechanism 71 is connected to the tablet compartment body 72 or the tablet retrieval auxiliary mechanism, and is used to drive the tablet compartment body 72 or the tablet retrieval auxiliary mechanism to move so that the push-out part 2 of the tablet retrieval auxiliary mechanism can correspond to different push-out positions. When different tablets 100 need to be retrieved, the tablet compartment body 72 or the tablet retrieval auxiliary mechanism is moved to the position corresponding to the different tablets 100 to push out the corresponding tablets 100.

[0098] Furthermore, taking a configuration where multiple compartments are spaced apart along the Z-axis as an example, the first displacement mechanism 71 can be connected to the tablet compartment body 72 to drive the tablet compartment body 72 to move along the Z-axis. The first displacement mechanism 71 can be a linear drive device such as an electric slide rail, a lead screw and nut pair 53, or a cylinder. These devices can provide stable and precise linear motion, ensuring that the tablet compartment body 72 can move accurately to the desired position in the Z-axis direction. The appropriate type of first displacement mechanism 71 can be flexibly selected according to the actual application scenario and requirements.

[0099] To facilitate centralized loading or unloading of multiple slices 100, the slice container body 72 can be fitted with a detachable material box, which is designed to store slices 100. This allows the entire material box to be loaded or unloaded at once, improving loading and unloading efficiency.

[0100] like Figure 4 As shown, this application also discloses a wafer ejection device, including a wafer ejection unit and a wafer storage unit.

[0101] The slide ejection device is located on one side of the slide compartment device and is used to transport the slide 100 ejected by the ejector 2 to the microscopic scanning device (not shown in the figure) for scanning.

[0102] Furthermore, such as Figure 6 As shown, it also includes a macroscopic image acquisition device (not shown in the figure); the macroscopic image acquisition device is used to identify the label area 101 and sample area 102 on the slice 100 before scanning; the slice removal device is used to transport the ejected slice 100 to the microscopic scanning device and expose the sample area 102 of the slice 100 to the scanning area of ​​the microscopic scanning device.

[0103] The macroscopic image acquisition device can be positioned above the ejection position of the slice 100 to scan and identify the corresponding area on the slice 100.

[0104] For example, when slide 100 is pushed a certain distance by ejector 2, its label area 101 is exposed to the acquisition area of ​​the macroscopic image acquisition mechanism. The macroscopic image acquisition mechanism identifies the label in label area 101 on slide 100 to obtain information such as patient information, pathology number, and staining type. Gripper 82 grasps slide 100 and pulls it out entirely. At this point, slide 100 is fully exposed to the acquisition area of ​​the macroscopic image acquisition device. The macroscopic image acquisition mechanism identifies sample area 102, enabling the slide removal mechanism to accurately expose the specimen area of ​​slide 100 to the scanning area of ​​the microscopic scanning mechanism, improving scanning accuracy and efficiency, and saving overall scanning time. (Sample area 102 contains tissue samples, carrying all the cell and structural information that needs to be observed.)

[0105] The macroscopic image acquisition device includes a macroscopic camera for capturing macroscopic images of slice 100 to identify the location and extent of the specimen region; and a label for scanning to read information from the label.

[0106] like Figure 5 As shown, the design of the film removal and ejection device includes a second displacement mechanism 81 and a gripper 82.

[0107] The gripper 82 grasps the ejected slice 100 in the thickness direction; the second displacement mechanism 81 is connected to the gripper 82 and is used to drive the gripper 82 to move. Taking the thickness direction of the slice 100 as parallel to the Z-axis as an example, the gripper 82 can also grasp the slice 100 that has been ejected a certain distance by moving it up and down, solving the problem of difficulty in grasping traditional slices with small gaps.

[0108] Taking the first displacement mechanism 71 as a Z-axis driven displacement mechanism as an example, the second displacement mechanism 81 can be an XY two-axis displacement mechanism, specifically including a base plate 811, a first sliding plate 812, a second sliding plate 815, a first drive assembly 813, and a second drive assembly 814. The first sliding plate 812 is slidably mounted on the base plate 811 along the X-axis direction; the first drive assembly 813 is mounted on the base plate 811 and connected to the first sliding plate 812, used to drive the first sliding plate 812 to slide; the second sliding plate 815 is slidably mounted on the first sliding plate 812 along the Y-axis direction; the second drive assembly 814 is mounted on the first sliding plate 812 and connected to the second sliding plate 815, used to drive the second sliding plate 815 to slide. The first drive assembly 813 and the second drive assembly 814 can be linear displacement drive mechanisms such as lead screw motors, linear motors, electric push rods, or cylinders. The specific selection depends on factors such as displacement accuracy, movement speed, and cost budget, and is not limited.

[0109] The gripper 82 is mounted on the second sliding plate 815, and it can be an electric gripper 82, a pneumatic gripper 82, a hydraulic gripper 82, etc. A grating assembly (not shown in the figure) can be installed on one side of the first sliding plate 812 and the second sliding plate 815 to detect the stroke and improve the positioning accuracy.

[0110] The workflow of the designed wafer ejection and retraction equipment is as follows:

[0111] 1. The ejector 2 ejects the slice 100 to be scanned and exposes the label area 101 to the macroscopic image acquisition device. Simultaneously with the ejection of the slice 100, the second moving mechanism moves the gripper 82 to the gripping position.

[0112] 2. The macroscopic image acquisition device takes a picture of the label area 101.

[0113] 3. The gripper 82 clamps the slice 100 and pulls it out of the slice container body 72 under the drive of the second displacement mechanism 81.

[0114] 4. The macroscopic image acquisition device takes a picture of the sample area 102. At the same time, the push-out motor 33 drives the cam 31 to reverse and return to its original position. Then, under the action of the elastic element 61, the push-out element 2 moves and resets along the guide rail 23.

[0115] 5. The second moving mechanism drives the gripper 82 to hold the slice 100 and move it to the microscopic scanning device, so that the sample area 102 is exposed to the scanning area of ​​the microscopic scanning device, and the imaging group of the microscopic scanning device scans the slice 100.

[0116] 6. After the scan is completed, the second moving mechanism drives the gripper 82 to hold the slice 100 and move it back into the slide compartment body 72. At this time, it is not fully inserted.

[0117] 7. The gripper 82 releases its grip on the slice 100 and, driven by the second displacement mechanism 81, retracts and resets, closing the gripper. Then, driven by the second displacement mechanism 81, it pushes the slice 100, completely pushing the slice 100 into the slice compartment body 72.
