Technical Field

[0001] The present invention relates to a mechanism for lifting a basket, and particularly to a multi-functional basket lifting mechanism. In addition, the present invention further relates to a sample storage device.

Background Art

[0002] The sample storage device is a cryogenic storage device and is widely applied to the field of storing biological samples.

[0003] Regarding a conventional sample storage device, refer to a Chinese patent with a publication number of "CN219097714U" and an invention title of "Double Basket Type Sample Loading and Unloading System". In the tank body, a basket for storing a biological sample storage plate-shaped holder via a support frame is provided. Above the sample inlet and outlet of the tank body, a lifting well assembly for operating the basket is provided. The lifting well assembly is used to lift the basket in the pipe body from the inlet and outlet and take out the plate-shaped holder in the basket by a scooping plate mechanism (pushing plate).

Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to realize operations on samples in various areas, the sample storage device is provided with two sets of fixed lifting well assemblies. Such fixed lifting well assemblies cannot move, cannot be operated flexibly, and are not suitable for reuse. When it is necessary to operate multiple areas, separate lifting wells must be provided. This increases the cost of the entire device. And in the sample storage device, the lifting well assembly only has the function of lifting the basket, and it is necessary to separately provide a scooping plate mechanism to operate the plate-shaped holder. Such a separate-type design of the lifting well assembly and the scooping plate mechanism is difficult for operators to install and maintain.

[0044] The following will describe specific embodiments of the present invention in more detail with reference to the drawings and examples. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] <Example 1> Referring to Figures 1 to 14, the multi-functional basket lifting mechanism of this embodiment includes a lifting well assembly, a scoop plate assembly, and a lifting well lifting device. The scoop plate assembly includes a mounting case 1 with openings at both the front and rear ends. Inside the mounting case are a scoop plate 2 and a scoop plate displacement drive assembly that drives the scoop plate to move back and forth.

[0046] The lifting well lifting device includes a fixed frame 3 that is fixedly connected to the mounting case, and a lifting drive module 4 that is fixedly mounted to the fixed frame.

[0047] The lifting well assembly includes a lifting well 5 with an open bottom, a basket connecting member 6 located inside the lifting well, and a basket connecting member lifting drive device that drives the basket connecting member to move vertically up and down inside the lifting well.

[0048] The output terminal of the lifting drive module is connected to the lifting well, and a plate-shaped holder inlet / outlet 7 corresponding to the scoop plate is provided at the bottom of the lifting well.

[0049] According to the multi-functional basket lifting mechanism of the present invention, the mounting case of the scoop plate assembly is provided with a lifting drive module that drives the lifting well to be raised and lowered via a fixed frame. In this way, the multi-functional basket lifting mechanism is capable of performing a lifting operation on the basket, and the lifted basket can also have its plate-shaped holder extracted by the scoop plate mechanism. Thus, it combines both a basket lifting function and a plate-shaped holder extraction function.

[0050] Compared to conventional lifting well assemblies, integrating the scoop plate assembly and the lifting well assembly makes installation and maintenance easier for operators.

[0051] Simultaneously, this multi-functional basket lifting mechanism allows for the connection of other displacement modules via a fixed frame, thereby enabling the lifting drive module and other displacement modules to form a three-dimensional displacement mechanism. A single lifting well assembly can then operate baskets in multiple areas, thereby reducing the number of lifting well assemblies, lowering the overall equipment cost, and improving the flexibility of the lifting well assemblies.

[0052] The lifting well assembly is used to operate the basket, and a basket connecting member provided therein can be connected to the basket. In this embodiment, the basket connecting member is a four-claw robot, and its specific structure can be found in the Chinese patent with publication number "CN112478760A" and the title of the invention "Plate-shaped holder clamping device". The basket connecting member may also be connected to the basket by employing a connecting hook, an electromagnetic or negative pressure suction device, etc.

[0053] In this embodiment, the basket connecting member includes a substrate 50 and several clamping claws 51. A clamping claw connecting block 52 is connected to the tips of the clamping claws, and connecting pins 53 are provided on the clamping claw connecting block. Guide ribs 54 are provided on the surface of the substrate that cooperate to slide relative to the clamping claw connecting block and extend radially. A drive plate 55 is provided above the substrate, and the central shaft of the drive plate is rotatably connected to the substrate. Curved guide holes 56 corresponding to the connecting pins are provided on the surface of the drive plate, and these curved guide holes are non-arc holes, with the tips of the connecting pins positioned within the curved guide holes. A worm wheel 57 is provided at the end of the central shaft of the drive plate, and the worm wheel is driven to rotate by a worm 58, thereby driving the drive plate to rotate, and thereby driving the connecting pins to move along the curved guide holes. Because the curved guide holes are non-arc holes, the connecting pins move along the guide ribs below them due to the action of the drive guide holes, thereby enabling the clamping claws to extend and retract.

[0054] When installed, a gantry is provided above the drive plate, fixed and connected to the base plate. The top plate of the gantry is fixed and connected to an L-shaped connecting frame. Both sides of the connecting frame cooperate with guide rails inside the lifting well by sliders. Connecting through holes are provided on the surface of the connecting frame. A connecting column mounting frame is provided on the chain, and a connecting column is provided on the connecting column mounting frame. The ends of the connecting columns are located within the connecting through holes. During raising and lowering, the chain drives the connecting column mounting frame and the connecting column to raise and lower, thereby driving the connecting frame and basket connecting member to raise and lower.

[0055] The basket connecting member lifting drive device is used to drive the basket connecting member to move vertically up and down along the lifting well, and may be a linear displacement device such as a pinion plate holder type lifting drive mechanism, a chain type lifting device, an air cylinder, an oil cylinder, or an electric cylinder.

[0056] In this embodiment, the basket connecting member lifting drive device is a sprocket-chain type lifting device, and includes sprockets 8 provided at both the upper and lower ends of the lifting well, a chain 9 wrapped around the sprockets, and a sprocket drive motor 10 that drives the sprockets to rotate, and the basket connecting member is connected to the chain via a connecting frame 11. During operation, the output end of the sprocket drive motor drives the chain to rotate via the sprockets, thereby driving the connecting frame and basket connecting member connected to the chain to move up and down.

[0057] Preferably, the basket connecting member lifting drive device further includes a tensioning device, the tensioning device including an adjustment plate 45, a first tension sprocket 46 whose wheel body engages with a chain and whose central shaft is fixedly connected to the adjustment plate, a second tensioner 47 whose wheel body engages with a chain and whose central shaft is fixedly connected to a lifting well, and an adjustment shaft 49 whose one end is fixedly connected to the adjustment plate and whose other end is screwed into a fixing plate 48, the fixing plate being fixedly provided on the surface of the lifting well.

[0058] By providing a tensioning device, the operator can easily adjust the tightness of the sprocket.

[0059] The adjustment plate is located on the outer surface of the lifting well, and the main shaft of the first tension sprocket is fixedly connected to the adjustment plate through the lifting well. Guide holes may be provided on the surface of the adjustment plate, and pin posts on the surface of the lifting well are located within these guide holes to guide the adjustment plate.

[0060] The adjustment shaft is screwed into the fixing plate, and its end is fixed and connected to the adjustment plate. When it is necessary to adjust the slack in the chain, the operator drives the adjustment shaft to move the adjustment plate, which in turn drives the first tension sprocket to move. Since the first and second tension sprockets are arranged alternately, the chain is gradually tensioned as the first tension sprocket moves.

[0061] The lifting drive module is used to drive the lifting well up and down, allowing the bottom end of the lifting well to move up and down directly above the basket, thereby connecting the basket connecting member to the basket. The lifting drive module is a one-dimensional linear displacement drive device, preferably an electric cylinder.

[0062] The fixed frame is used to mount the lifting drive module and also to connect other displacement modules, forming a three-dimensional displacement mechanism that drives the lifting well and scoop plate assembly to move to a predetermined area and to operate the basket in that area.

The end of the lever is connected to a lifting well and drives the lifting well to move up and down in the vertical direction.

[0064] The scoop plate assembly is used to extract plate-shaped holders in a basket and contains a scoop plate and a scoop plate displacement drive assembly that drives the scoop plate to move. The scoop plate displacement drive assembly drives the scoop plate to move along a single-stage guide rail 15 inside the mounting case, so that the scoop plate can extend from the end of the mounting case and enter the lifting well from the plate-shaped holder entrance at the bottom of the lifting well, thereby allowing the plate-shaped holder inside the lifting well to be extracted.

[0065] During operation, the basket connecting member in the lifting well is driven by the basket connecting member lifting drive device to rise and move the basket 16 to a predetermined position. Next, the scoop plate is driven by the scoop plate displacement drive assembly to protrude from the opening at the end of the mounting case and enter the lifting well from the plate holder entrance. At this time, the scoop plate is positioned directly below the plate holder. Next, the basket is lowered slightly, causing the plate holder to fall onto the surface of the scoop plate. After this, the scoop plate is driven by the scoop plate displacement drive assembly to transport the plate holder from the basket into the mounting case and output from the opening at the other end of the mounting case, after which the operator or robot can easily operate the plate holder.

[0066] The scoop plate displacement drive assembly may be a pinion plate holder type displacement drive device, or a displacement device such as an electric cylinder, air cylinder, or oil cylinder. In this embodiment, the scoop plate displacement drive assembly is a two-stage displacement drive mechanism. Specifically, the scoop plate drive assembly includes a single-stage slide plate 17 that can slide along a single-stage guide rail in a mounting case, a single-stage linear displacement drive mechanism to which the machine body is fixedly connected to the mounting case and which can drive the single-stage slide plate to move back and forth along the single-stage guide rail in the mounting case, a second-stage slide plate 19 that can slide along a second-stage guide rail 18 on the surface of the single-stage slide plate, and a second-stage linear displacement drive mechanism to which the machine body is fixedly connected to the single-stage slide plate and which can drive the second-stage slide plate to move back and forth.

[0067] The single-stage linear displacement drive mechanism includes a single-stage drive motor 20, which is fixedly connected to the top plate of the mounting case. The output shaft of the single-stage drive motor is connected to a single-stage gear 22 via a timing pulley transmission 21. The single-stage gear is rotatably connected to a mounting plate 23 in the mounting case. The single-stage gear further meshes with a single-stage plate holder 24 on a single-stage slide plate, thereby driving the single-stage plate holder and the single-stage slide plate to move along a single-stage guide rail in the mounting case.

[0068] Similarly, the two-stage linear displacement drive mechanism includes a two-stage drive motor 26, to which the machine body is fixedly connected to the single-stage slide plate via a motor mounting frame 25. The output shaft of the two-stage drive motor is connected to a two-stage gear 27, which meshes with a two-stage plate holder 44 on the two-stage slide plate, thereby driving the two-stage slide plate to move along the two-stage guide rail on the surface of the single-stage slide plate. The scoop plate is connected to the front end of the two-stage slide plate.

[0069] By providing a two-stage displacement drive mechanism, the stroke of the scoop plate displacement drive assembly is increased while its overall length is reduced, making it easier to connect to components such as lifting wells.

[0070] Preferably, the fixed frame is further provided with a pipette assembly 28 for aspirating the sample tube.

[0071] By providing a pipette assembly, operation on a single sample tube is enabled, further enhancing the multi-functionality of the multi-functional basket lifting mechanism.

[0072] The pipette assembly includes a pipette 29 and a pipette lifting mechanism 30 that drives the pipette up and down, the body of which is fixed to the bottom plate of a fixed frame.

[0073] <Example 2> Referring to Figures 15 to 17, this embodiment discloses a sample storage device, which includes a refrigerated box 31, with an operating chamber 32 provided above the refrigerated box. Inside the operating chamber are a multi-functional basket lifting mechanism 33 and a two-dimensional movement mechanism that drives the multi-functional basket lifting mechanism to move horizontally.

[0074] The two-dimensional movement mechanism includes two sets of lateral displacement drive devices 34, respectively, provided on the left and right walls of the control room, and longitudinal displacement drive devices 35, with both ends of the machine body provided at the output terminals of the lateral displacement drive devices. The fixed frame of the multi-functional basket lifting mechanism is connected to the output terminals of the longitudinal displacement drive devices.

[0075] The multi-functional basket lifting mechanism is By providing a two-dimensional movement mechanism, two-dimensional displacement drive is achieved for the multi-functional basket lifting mechanism. By combining this with a lifting drive module, a three-dimensional displacement mechanism is formed, allowing the lifting well to be driven to a predetermined position above the refrigerated box. This enables extraction operations to be performed on the basket inside the refrigerated box at that location. Compared to conventional sample storage devices, the multi-functional basket lifting assembly combines basket lifting and plate-shaped holder extraction functions, offers greater integration, more flexible operation, and a relatively lower overall equipment cost.
