Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a hopper device for a pathological slide scanner. Background Technology

[0002] A pathology slide scanner is a medical device that converts traditional glass pathology slides into high-definition array images, primarily used to help doctors observe and analyze human tissue samples more conveniently.

[0003] In a pathological slide scanner system, the slide storage mechanism is a key link between manual patching and automatic scanning. Its storage capacity, slide box positioning accuracy, and ease of loading and unloading directly affect the overall scanning efficiency.

[0004] Existing pathological slide scanners mostly use multi-layer drawer-type slide boxes to store pathological slides. The whole machine clamping module then clamps and transports the slide boxes to the detection module for scanning. However, many slide boxes currently lack a dedicated clamping structure. During the rotation of the pathological slides, the slide boxes may shift, causing the whole machine clamping module to be unable to accurately pick up and put down the slide boxes. In some cases, the slide boxes may even be thrown out due to centrifugal force during the rotation of the pathological slides, affecting the accuracy of subsequent transportation and the scanning efficiency of the whole machine. Utility Model Content

[0005] Based on the above description, this utility model provides a hopper device for a pathological slide scanner, which aims to solve the problem that the lack of a clamping structure in the basket of the pathological slide scanner causes the basket to shift when being picked up or placed, thus affecting the scanning efficiency of the whole machine.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hopper device for a pathological slide scanner, characterized in that it comprises: The hopper mechanism includes a storage turntable and multiple baskets, all of which are disposed on the storage turntable and are spaced apart around the axis of the storage turntable. Multiple clamping mechanisms are provided on the storage turntable, with one clamping mechanism provided between every two adjacent baskets; A drive mechanism, the output of which is connected to the storage turntable.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the clamping mechanism includes a basket stop block and clamping members. The basket stop block has a first wall surface and a second wall surface. The first wall surface and the second wall surface are symmetrical about a defined axis. At least one clamping member is provided on both the first wall surface and the second wall surface.

[0009] Furthermore, the storage turntable has a first positioning groove for each of the baskets.

[0010] Furthermore, the bottom wall of the first positioning groove is inclined.

[0011] Furthermore, the storage turntable has at least one positioning hole for each of the first positioning slots, and each basket has a positioning protrusion for each positioning hole.

[0012] Furthermore, the storage turntable has a second positioning groove for each of the basket stops.

[0013] Furthermore, the storage turntable is provided with a baffle, which is disposed between all the baskets, and all the baskets abut against the baffle.

[0014] Furthermore, the driving mechanism includes a drive motor and a rotating shaft. One end of the rotating shaft is connected to the output end of the drive motor, or one end of the rotating shaft is connected to the output end of the drive motor via a transmission component, and the other end of the rotating shaft is connected to the storage turntable.

[0015] Furthermore, the driving mechanism includes a hollow rotating platform, the driving motor is disposed inside the hollow rotating platform, and one end of the rotating shaft passes through the opening of the hollow rotating platform and is connected to the storage turntable.

[0016] Furthermore, the hopper device of the pathology slide scanner also includes a positioning detection component, which includes a position detector and at least one mating member. The mating member is disposed on the storage turntable, and the detection end of the position detector faces the mating member.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: (1) The present application clamps the basket by means of a clamping mechanism to avoid the basket from shifting due to centrifugal force when the storage turntable rotates. Thus, the basket is more accurately clamped due to the limiting effect of the clamping mechanism, which improves the scanning efficiency of the pathological slide scanner.

[0018] (2) By tilting the bottom wall of the first positioning groove of the storage turntable, when the basket is installed in the first positioning groove, the basket as a whole also tilts into the storage turntable. At this time, the slices inside the basket will also tilt inward, so that when the storage turntable rotates, the slices inside the basket will not be thrown out due to centrifugal force.

[0019] (3) This application sets up a position detector and multiple mating parts. The mating parts are set on the storage turntable and correspond one-to-one with the basket. This can accurately control the required angle of rotation of the storage turntable, so that the basket on the storage turntable can be accurately moved to the required position and the basket can be accurately clamped.

[0027] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a material storage device for a pathological slide scanner, including a material storage mechanism 100, multiple clamping mechanisms 200, and a drive mechanism 300. The material storage mechanism 100 includes a storage turntable 110 and multiple baskets 120. All baskets 120 are disposed on the storage turntable 110 and are spaced apart around the axis of the storage turntable 110. Multiple clamping mechanisms 200 are disposed on the storage turntable 110, with one clamping mechanism 200 disposed between every two adjacent baskets 120. The output end of the drive mechanism 300 is connected to the storage turntable 110.

[0028] For example, the storage turntable 110 and multiple baskets 120 can constitute a storage group, and there can be multiple storage groups arranged sequentially in a vertical direction, wherein the multiple storage turntables 110 are connected by a shaft column.

[0029] In this embodiment, a clamping mechanism 200 is provided between adjacent baskets 120 to clamp the baskets 120. When the driving mechanism 300 drives the storage turntable 110 to rotate, the baskets 120 will not be deflected due to the centrifugal force generated during the rotation. Thus, due to the limiting effect of the clamping mechanism 200, the baskets 120 are clamped more accurately, which improves the scanning efficiency of the pathological slide scanner.

[0030] Reference Figure 2 and Figure 4 As shown, in some embodiments, the clamping mechanism 200 includes a basket stop 210 and a clamping member 220. The basket stop 210 is provided with a first wall surface 211 and a second wall surface 212. The first wall surface 211 and the second wall surface 212 are symmetrical about the defined axis 213. At least one clamping member 220 is provided on both the first wall surface 211 and the second wall surface 212.

[0031] In this embodiment, the clamping members 220 on both sides of the basket 120 cooperate to clamp the basket 120, which can prevent the basket 120 from shifting during the rotation of the storage turntable 110.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments, for example, the clamping member 220 can be a spring, and the shape of the spring can be "P" shaped, convex, etc.

[0033] In this embodiment, the spring sheet is fixed to the first wall surface 211 and the second wall surface 212 of the basket stop block 210 by screws. The bent part of the spring sheet protrudes outward and reserves space for elastic deformation. The bent part of the spring sheet abuts against the corresponding basket 120 and clamps the spring sheet on the other side of the basket 120 to prevent the basket 120 from shifting when the storage turntable 110 rotates or is picked up or put down. Moreover, the spring sheet has a simple structure, is easy to replace and maintain, and has low cost.

[0034] Reference Figure 2 As shown, in some embodiments, the storage turntable 110 has a first positioning slot 111 for each basket 120.

[0035] In this embodiment, the first positioning groove 111 can be adapted to the bottom shape of the basket 120. When the basket 120 is placed into the first positioning groove 111, the basket 120 is initially positioned, and at the same time, the clamping mechanism 200 clamps the basket 120 to form a "three-dimensional positioning", ensuring that the basket 120 does not move in any direction within the first positioning groove 111.

[0036] Reference Figure 2 and Figure 3 As shown, in some embodiments, the bottom wall 1111 of the first positioning groove 111 is inclined.

[0037] In this embodiment, the bottom wall 1111 of the first positioning groove 111 is inclined toward the center of the storage turntable 110. The basket 120 is also inclined in the same way when it is installed in the first positioning groove 111. When the storage turntable 110 rotates, the centrifugal force on the basket 120 can be reduced. In addition, the clamping mechanism 200 clamps the basket 120. At this time, the pathological slides inside the basket 120 will also be inclined toward the center of the storage turntable 110. This will also reduce the centrifugal force on the pathological slides during the rotation of the storage turntable 110 and prevent the pathological slides from being thrown out.

[0038] Reference Figures 2 to 4 As shown, in some embodiments, at least one positioning hole 112 is provided on the storage turntable 110 corresponding to each first positioning groove 111, and a positioning protrusion 121 is provided on the basket 120 at the position corresponding to the positioning hole 112.

[0039] For example, the number of positioning holes 112 opened on the storage turntable 110 corresponding to each first positioning slot 111 can be two.

[0040] In this embodiment, the positioning hole 112 in the first positioning groove 111 is configured to cooperate with the positioning protrusion 121 on the basket 120, which further ensures the accuracy of the basket 120 installation and positioning.

[0041] Reference Figure 3 As shown, in some embodiments, the sidewall of the first positioning groove 111 facing away from the center of the storage turntable 110 is open, and part of the positioning hole 112 is located at the edge of the storage turntable 110. At this time, the positioning hole 112 is an open structure, which facilitates accurate positioning when the basket 120 is placed on the storage turntable 110.

[0042] Reference Figure 2 and Figure 3 As shown, in some embodiments, the storage turntable 110 has a second positioning groove 113 corresponding to each basket stop 210.

[0043] In this embodiment, the second positioning groove 113 facilitates the positioning and installation of the basket stop 210, so that the entire clamping mechanism 200 can accurately clamp the basket 120.

[0044] Reference Figure 2 As shown, in some embodiments, the storage turntable 110 is provided with a baffle 114, which is disposed between all the baskets 120, and all the baskets 120 abut against the baffle 114.

[0045] For example, the baffle 114 can be a ring structure, and the cross-section of the baffle 114 can be a circle or a regular polygon, etc.

[0046] In this embodiment, the baffle 114 further limits the basket 120, making the installation position of the basket 120 more accurate.

[0047] Reference Figure 1 As shown, in some embodiments, the drive mechanism 300 includes a drive motor 310 and a rotating shaft 320. One end of the rotating shaft 320 is connected to the output end of the drive motor 310, or one end of the rotating shaft 320 is connected to the output end of the drive motor 310 via a transmission member, and the other end of the rotating shaft 320 is connected to the storage turntable 110.

[0048] For example, when the rotating shaft 320 is coaxial with the drive motor 310, one end of the rotating shaft 320 can be connected to the output end of the drive motor 310, or one end of the rotating shaft 320 can be connected to the output end of the drive motor 310 through a transmission component, wherein the transmission component can be a coupling or the like. If the rotating shaft 320 is axially perpendicular to the drive motor 310, the rotating shaft 320 and the drive motor 310 are connected and driven by a transmission component, wherein the transmission component can include a meshing pair of a face gear and a cylindrical gear or a pair of meshing bevel gears, or the transmission component can be a worm gear mechanism or the like.

[0049] In this embodiment, the drive motor 310 is controlled by the control module of the pathology slide scanner. When the control module of the pathology slide scanner sends a drive signal to the drive motor 310, the drive motor 310 drives the storage turntable 110 to rotate.

[0050] Reference Figure 1 As shown, in some embodiments, the drive mechanism 300 includes a hollow rotating platform 330, a drive motor 310 is disposed inside the hollow rotating platform 330, and one end of the rotating shaft 320 passes through the opening of the hollow rotating platform 330 and is connected to the storage turntable 110.

[0051] In this embodiment, the hollow rotating platform 330 serves as an integrated frame for the drive motor 310 and the rotating shaft 320.

[0052] Reference Figure 6 As shown, in some embodiments, the hopper device includes a positioning detection component 400, which includes a position detector 410 and at least one mating member 420. The mating member 420 is disposed on the storage turntable 110, and the detection end of the position detector 410 faces the mating member 420.

[0053] For example, the position detector 410 is a photoelectric sensor.

[0054] In this embodiment, when there is only one mating component 420, it is positioned between the storage tray 110 and the rotating shaft 320, and the position detector 410 is positioned on the side of the hollow rotating platform 330. When the position detector 410 detects the mating component 420, it indicates that the storage tray 110 is in the starting position. Then, the control module of the pathology slide scanner controls the drive motor 310 to rotate the storage tray 110 to the designated position. Each rotation of the storage tray 110 triggers the position detector 410 again after the mating component 420 is engaged, at which point the storage tray 110 accurately returns to its starting position. The position detector 410's detection of the mating component 420 determines whether the storage tray 110 is in the starting position, ensuring that the basket 120 can accurately move to the desired gripping position during subsequent rotations.

[0055] In other embodiments, when the number of mating parts 420 corresponds to the number of first positioning slots on a storage turntable 110, the mating parts 420 are disposed on the edge of the storage turntable 110 and correspond one-to-one with the first positioning slots on the storage turntable 110. The rotation angle of the storage turntable 110 is determined by whether the position detector 410 detects the mating parts 420, and then the rotation or stop of the drive motor 310 is controlled to control the storage turntable 110 to rotate to the designated position, ensuring that the basket 120 is accurately moved to the position to be gripped.

[0056] Reference Figure 7 As shown, the output terminal of the position detector 410 is electrically connected to the input terminal of the control module of the pathology slide scanner, and the input terminal of the drive motor 310 is electrically connected to the output terminal of the control module of the pathology slide scanner.

[0057] When the mating part 420 on the storage turntable 110 moves to the position corresponding to the detection end of the position detector 410, the position detector 410 will send a position signal to the control module of the pathology slide scanner, and then the control module of the pathology slide scanner will send a stop signal to the drive motor 310.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
