Figure 4 This is an assembly drawing of the carrier plate 600, the transfer mechanism 500, the transfer plate 710, and the first motor 720 according to some embodiments of this application. Figure 5This is an assembly diagram of a transfer mechanism 500, a transfer plate 710, and a first motor 720 according to some embodiments of this application.

[0034] The biological sample storage device includes a placement rack, a storage tray 100, a carrier plate 300, and a transfer mechanism 500.

[0035] The placement rack defines a placement position, which has an opening in a first horizontal direction. Specifically, the placement rack can be a frame structure composed of plates or rods, and the first horizontal direction can be left-right, with an opening on either the left or right side.

[0036] The storage tray 100 is placed in the placement position. The storage tray 100 is provided with a plurality of compartments arranged along the first horizontal direction. The compartments are used to place biological sample boxes 200, which are used to place biological samples. Understandably, the storage tray 100 is movably disposed in the placement position; it can be located in the placement position or detached from it. Multiple compartments can increase storage capacity.

[0037] The carrier tray 300 is used to receive the storage tray 100 from the placement rack, and the carrier tray 300 is provided with a plurality of temporary storage positions arranged along the first horizontal direction. The plurality of box positions and the plurality of temporary storage positions are arranged along a second horizontal direction, which is perpendicular to the first horizontal direction. The carrier tray 300 can receive the storage tray 100 manually or through some automated mechanism, and the multiple temporary storage positions can improve the efficiency of access. Understandably, the second horizontal direction can be a front-to-back direction.

[0038] The transfer mechanism 500 is movably disposed above the carrier tray 300 along the first horizontal direction and the second horizontal direction, and the transfer mechanism 500 is used to push the biological sample box 200 between the box position and the temporary storage position.

[0039] The biological sample storage device provided in this embodiment, through the configuration of the transfer mechanism 500, enables the biological sample box 200 to be transferred between multiple box positions and multiple temporary storage positions, thereby improving the efficiency of access.

[0040] The carrier tray 300 can also be used to place the temporary storage tray 400. The carrier tray 300 is provided with the plurality of temporary storage positions (i.e., the plurality of temporary storage positions are defined by the temporary storage tray 400) through the temporary storage tray 400. The storage tray 100 and the temporary storage tray 400 are arranged along the second horizontal direction. It can be understood that when transferring the biological sample box 200, the carrier tray 300 simultaneously holds the storage tray 100 and the temporary storage tray 400. The temporary storage tray 400 can receive the first biological sample box 200 from the first storage tray 100 through the box-moving mechanism 500, then receive the second biological sample box 200 from the second storage tray 100 through the box-moving mechanism 500, and then receive the third biological sample box 200 from the third storage tray 100 through the box-moving mechanism 500. Thus, the temporary storage tray 400 can deliver multiple biological sample boxes 200 at once. The same applies when storing biological sample boxes 200, thereby improving the efficiency of storage and retrieval. Moreover, this box-moving method is relatively stable and can prevent the biological sample boxes 200 from falling.

[0041] This embodiment uses a horizontal storage tray 100 and a temporary storage tray 400 to transfer the biological sample box 200. Compared with vertically arranged storage trays and temporary storage trays, and by replacing the temporary storage trays with temporary storage racks, the structure is simple, stable, and low in cost.

[0042] In some embodiments, the biological sample storage device further includes a carrier plate 600, and the transfer mechanism 500 is movably disposed on the carrier plate 600 along the first horizontal direction. The carrier plate 600 is movably disposed above the carrier tray 300 along the second horizontal direction. Moving the transfer mechanism 500 along the first horizontal direction can push the biological sample container 200 to different positions, and moving the transfer mechanism 500 along the second horizontal direction can move the biological sample container 200 between the container position and the temporary storage position.

[0043] In some embodiments, the transfer mechanism 500 is connected to a transfer plate 710, and a first motor 720 is fixed to the transfer plate 710. The first motor 720 drives the transfer plate 710 to move along the horizontal first direction on the carrier plate 600. Specifically, the output shaft of the first motor 720 is connected to a gear, which meshes with and is fixed to the rack of the carrier plate 600, thereby ensuring the stability of the transmission. The transfer plate 710 and the carrier plate 600 can be connected by a guide rail and a guide groove. For example, the carrier plate 600 is provided with a guide rail, and the transfer plate 710 is provided with a guide groove.

[0044] In some embodiments, the transfer mechanism 500 includes at least one second motor 510, which is connected to a lever 520. The second motor 510 drives the lever 520 to rotate. The output shaft of the second motor 510 is along the second horizontal direction, and the lever 520 is perpendicular to the output shaft of the second motor 510. The lever 520 is used to move the biological sample container 200 between the container position and the temporary storage position. That is, the extension direction of the lever 520 is perpendicular to the output shaft of the second motor 510. Thus, when the transfer mechanism 500 moves along the second horizontal direction, the second motor 510 keeps the lever 520 horizontal to avoid interference, and when pushing the container, the second motor 510 keeps the lever 520 vertical to achieve the pushing of the container.

[0045] In some embodiments, the at least one second motor 510 includes two second motors 510 arranged opposite each other along the second horizontal direction, with their output shafts facing away from each other. Thus, one second motor 510 can move the biological sample container 200 from the temporary storage position to the container position, and the other biological sample container 200 can move from the container position to the temporary storage position, avoiding the problem of excessive travel when using only one second motor 510.

[0046] In some embodiments, the biological sample storage device further includes two drive belt assemblies 800 arranged along the first horizontal direction. Each drive belt assembly 800 includes two drive wheels 810 fixed above the carrier plate 300 and a drive belt 820 wound around the two drive wheels 810. The carrier plate 600 is movably disposed on the drive belts 820 of the two drive belt assemblies 800 along the second horizontal direction. At least one drive wheel 810 is connected to a third motor 900, which drives the corresponding drive wheel 810 to rotate. This method ensures the reliability of the transmission of the large-sized carrier plate 600.

[0047] Specifically, the carrier plate 300 is provided with multiple columns, and each column is equipped with a drive wheel 810. The first drive belt assembly includes a first drive wheel and a second drive wheel, and the second drive belt assembly includes a third drive wheel and a fourth drive wheel. The first drive wheel can be connected to a third motor 900, and a drive rod can be connected between the first and third drive wheels to achieve synchronous rotation of the first and third drive wheels.

[0048] In some embodiments, the transfer mechanism 500 includes a transfer block, resulting in a simple structure and low cost. Specifically, the transfer block may include an electromagnet, and / or the transfer block may be movable up and down. The up-and-down movement of the transfer block (achieved through various means such as gears, racks, or belts) can both prevent interference between the transfer block and the biological sample container 200 and enable the pushing of the biological sample container 200. Specifically, the electromagnet is also used to pick up and place the storage tray 100; that is, when it is magnetic, it attracts the storage tray 100, moves the storage tray 100 into position along the first horizontal direction, and then demagnetizes it. The electromagnet can transfer the biological sample container 200 when it is magnetic and when it is not magnetic. In some embodiments, the biological sample storage device further includes a transfer mechanism and a transfer position. The carrier tray 300 is mounted on the transfer mechanism, which is used to move the carrier tray 300 between the placement rack and the transfer position. The transfer position is used to transfer the biological sample. Specifically, the transfer mechanism may include various transfer mechanisms such as rollers.

[0049] In some embodiments, the biological sample storage device further includes a tray retrieval mechanism movably mounted on the carrier tray 300 to move the storage tray 100 between the placement position and the carrier tray 300. For example, the tray retrieval mechanism can retrieve and place the storage tray by hooking, or it can move the storage tray 100 using various methods such as gears and racks.

[0050] In some embodiments, the rack defines a plurality of placement positions arranged in a matrix. This increases storage capacity.

[0051] In some embodiments, the biological sample box 200 defines a plurality of placement slots for placing pathology embedding boxes, which embed the biological sample in a paraffin block. In other embodiments, other biological samples may also be used.

[0052] This embodiment also provides a biological sample storage device, including a placement rack, a storage tray 100, a carrier plate 300, and a transfer mechanism 500.

[0053] The placement rack defines a placement position, which has an opening in a first horizontal direction. Specifically, the placement rack can be a frame structure composed of plates or rods, and the first horizontal direction can be left-right, with an opening on either the left or right side.

[0054] The storage tray 100 is placed in the placement position. The storage tray 100 is provided with a plurality of compartments arranged along the first horizontal direction. The compartments are used to place biological sample boxes 200, which are used to place biological samples. Understandably, the storage tray 100 is movably disposed in the placement position; it can be located in the placement position or detached from it. Multiple compartments can increase storage capacity.

[0055] The carrier tray 300 is used to receive the storage tray 100 from the placement rack, and the carrier tray 300 is provided with a plurality of temporary storage positions arranged along the first horizontal direction. The plurality of box positions and the plurality of temporary storage positions are arranged along a second horizontal direction, which is perpendicular to the first horizontal direction. The carrier tray 300 can receive the storage tray 100 manually or through some automated mechanism. The multiple temporary storage positions can improve the efficiency of access. Understandably, the second horizontal direction can be a front-to-back direction.

[0056] The transfer mechanism 500 is movably disposed above the carrier tray 300. The transfer mechanism 500 includes at least one second motor 510. The second motor 510 is connected to a lever 520. The second motor 510 is used to drive the lever 520 to rotate. The output shaft of the second motor 510 is along the horizontal second direction. The lever 520 is perpendicular to the output shaft of the second motor 510. The lever 520 is used to push the biological sample box 200 to move between the box position and the temporary storage position.

[0057] The biological sample storage device provided in this embodiment, through the configuration of the transfer mechanism 500, allows the biological sample box 200 to be transferred between multiple box positions and multiple temporary storage positions, thereby improving the efficiency of access.

[0058] The carrier tray 300 can also be used to place the temporary storage tray 400. The carrier tray 300 is provided with the plurality of temporary storage positions (i.e., the plurality of temporary storage positions are defined by the temporary storage tray 400). The storage tray 100 and the temporary storage tray 400 are arranged along the second horizontal direction. The temporary storage tray 400 can receive the first biological sample box 200 from the first storage tray 100 through the box-moving mechanism 500, then receive the second biological sample box 200 from the second storage tray 100 through the box-moving mechanism 500, and then receive the third biological sample box 200 from the third storage tray 100 through the box-moving mechanism 500. Thus, the temporary storage tray 400 can deliver multiple biological sample boxes 200 at one time. The same applies when storing biological sample boxes 200, thereby improving the efficiency of storage and retrieval. Moreover, this box-moving method is relatively stable and can prevent the biological sample boxes 200 from falling.

[0059] There can be multiple box-moving mechanisms 500. One box-moving mechanism 500 moves along a first horizontal direction, another box-moving mechanism 500 moves along a second horizontal direction, or a single box-moving mechanism 500 can move along both the first and second horizontal directions.

[0060] The extension direction of the lever 520 is perpendicular to the output shaft of the second motor 510. Thus, when the box-moving mechanism 500 moves in the second horizontal direction, the lever 520 can be made horizontal by the second motor 510 to avoid interference. When pushing the box, the lever 520 can be made vertical by the second motor 510 to achieve the pushing of the box.

[0061] In some embodiments, the biological sample storage device further includes a carrier plate 600, and the transfer mechanism 500 is movably disposed on the carrier plate 600 along the first horizontal direction. The carrier plate 600 is movably disposed above the carrier tray 300 along the second horizontal direction. Moving the transfer mechanism 500 along the first horizontal direction can push the biological sample container 200 to different positions, and moving the transfer mechanism 500 along the second horizontal direction can move the biological sample container 200 between the container position and the temporary storage position.

[0062] In some embodiments, the transfer mechanism 500 is connected to a transfer plate 710, and a first motor 720 is fixed to the transfer plate 710. The first motor 720 drives the transfer plate 710 to move along the horizontal first direction on the carrier plate 600. Specifically, the output shaft of the first motor 720 is connected to a gear, which meshes with and is fixed to the rack of the carrier plate 600, thereby ensuring the stability of the transmission. The transfer plate 710 and the carrier plate 600 can be connected by a guide rail and a guide groove. For example, the carrier plate 600 is provided with a guide rail, and the transfer plate 710 is provided with a guide groove.

[0063] In some embodiments, the biological sample storage device further includes two drive belt assemblies 800 arranged along the first horizontal direction. Each drive belt assembly 800 includes two drive wheels 810 fixed above the carrier plate 300 and a drive belt 820 wound around the two drive wheels 810. The carrier plate 600 is movably disposed on the drive belts 820 of the two drive belt assemblies 800 along the second horizontal direction. At least one drive wheel 810 is connected to a third motor 900, which drives the corresponding drive wheel 810 to rotate. This method ensures the reliability of the transmission of the large-sized carrier plate 600.

[0064] Specifically, the carrier plate 300 is provided with multiple columns, and each column is equipped with a drive wheel 810. The first drive belt assembly includes a first drive wheel and a second drive wheel, and the second drive belt assembly includes a third drive wheel and a fourth drive wheel. The first drive wheel can be connected to a third motor 900, and a drive rod can be connected between the first and third drive wheels to achieve synchronous rotation of the first and third drive wheels.

[0065] In some embodiments, the at least one second motor 510 includes two second motors 510 arranged opposite each other along the second horizontal direction, with their output shafts facing away from each other. Thus, one second motor 510 can move the biological sample container 200 from the temporary storage position to the container position, and the other biological sample container 200 can move from the container position to the temporary storage position, avoiding the problem of excessive travel when using only one second motor 510.

[0066] In some embodiments, the biological sample storage device further includes a transfer mechanism and a transfer position. The carrier tray 300 is mounted on the transfer mechanism, which drives the carrier tray 300 to move between the placement rack and the transfer position. The transfer position is used to transfer the biological sample. Specifically, the transfer mechanism may include various transfer mechanisms such as rollers.

[0067] In some embodiments, the biological sample storage device further includes a tray retrieval mechanism movably mounted on the carrier tray 300 to move the storage tray 100 between the placement position and the carrier tray 300. For example, the tray retrieval mechanism can retrieve and place the storage tray by hooking, or it can move the storage tray 100 using various methods such as gears and racks.
