DETAILED DESCRIPTION

[0062] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0063] Example 1:

[0064] 1 to 14 , the multifunctional basket lifting mechanism of this embodiment includes a lifting well assembly, a shovel assembly, and a lifting well lifting device. The shovel assembly includes a mounting shell 1 with openings at both ends, and a shovel 2 and a shovel displacement drive assembly for driving the shovel to move forward and backward are provided within the mounting shell.

[0065] The hoist shaft lifting device includes a fixing frame 3 fixedly connected to the mounting shell, and a lifting drive module 4 whose body is fixedly mounted on the fixing frame;

[0066] The lifting shaft assembly includes a lifting shaft 5 with an opening at the bottom end, a basket connecting member 6 located in the lifting shaft, and a basket connecting member lifting and lowering driving device for driving the basket connecting member to vertically rise and fall in the lifting shaft;

[0067] The output end of the lifting drive module is connected to the lifting shaft, and the bottom of the lifting shaft is provided with a plate frame inlet and outlet 7 corresponding to the shovel plate.

[0068] The multifunctional basket lifting mechanism of the present invention has a lifting drive module that can drive the lifting shaft to rise and fall, which is installed on the mounting shell of the shovel plate assembly through a fixed frame. This enables the multifunctional basket lifting mechanism to not only lift the basket, but also extract the plate frame on it through the shovel plate mechanism after the basket is lifted, thereby making it have both basket lifting and plate frame extraction functions.

[0069] Compared with the original lifting shaft assembly, it integrates the shovel plate assembly and the lifting shaft assembly into one, which is convenient for operators to install and maintain.

[0070] At the same time, the multifunctional basket lifting mechanism can also be connected to other displacement modules through a fixed frame, so that the lifting drive module and other displacement modules form a three-dimensional displacement mechanism, so that a single lifting well assembly can operate the baskets in multiple areas respectively, thereby reducing the number of lifting well assemblies, reducing the overall cost of the equipment, and improving the flexibility of the lifting well assembly.

[0071] The lifting shaft assembly is used to operate the lifting basket. A lifting basket connector is provided within the lifting shaft assembly and is capable of connecting to the lifting basket. In this embodiment, the lifting basket connector is a four-claw manipulator. Its specific structure can be found in Chinese Patent Publication No. CN112478760A, entitled "A Clamping Device for a Plate Rack." Alternatively, the lifting basket connector can be connected to the lifting basket using a hook, electromagnetic, or negative pressure suction device.

[0072] In this embodiment, the basket connecting member includes a base plate 50 and a plurality of clamping jaws 51. The top of the clamping jaw is connected to a clamping jaw connecting block 52, and a connecting pin 53 is provided on the clamping jaw connecting block. The surface of the base plate is provided with a guide bar 54 that slides with the clamping jaw connecting block and extends radially. A driving plate 55 is provided above the base plate. The central axis of the driving plate is rotatably connected to the base plate. The surface of the driving plate is provided with a curved guide hole 56 corresponding to the connecting pin. The curved guide hole is not a circular hole, and the top of the connecting pin is set in the curved guide hole. A turbine 57 is provided at the end of the central axis of the driving plate. The turbine rotates under the drive of the worm 58, thereby driving the driving plate to rotate, and then driving the connecting pin to move along the curved guide hole. Because the curved guide hole is not a circular hole, the connecting pin moves along the guide bar below it under the action of the driving guide hole, thereby realizing the extension and retraction of the clamping jaw.

[0073] During installation, a gantry frame, fixed to the base plate, is installed above the drive plate. The gantry frame's top plate is fixedly connected to an L-shaped connecting frame. Sliders on both sides of the connecting frame engage with the guide rails inside the hoist shaft. The connecting frame has connecting holes on its surface. A connecting column mounting frame is installed on the chain, and connecting columns are installed on the connecting column mounting frame. The ends of the connecting columns are located in the connecting holes. During lifting, the chain drives the connecting column mounting frame and the connecting columns up and down, thereby driving the connecting frame and the basket connector to rise and fall.

[0074] The basket lifting connector lifting drive device is used to drive the basket lifting connector to lift vertically along the lifting shaft. It can be a linear displacement device such as a gear rack lifting drive mechanism, a chain lifting device, a cylinder, an oil cylinder or an electric cylinder.

[0075] In this embodiment, the basket handle connector lifting and lowering drive device is a sprocket and chain type lifting device, comprising sprockets 8 located at the upper and lower ends of the lift shaft, a chain 9 wound around the sprockets, and a sprocket drive motor 10 for driving the sprockets. The basket handle connector is connected to the chain via a connecting frame 11. During operation, the output end of the sprocket drive motor drives the chain through the sprocket, thereby driving the connecting frame and the basket handle connector connected to the chain to rise and fall.

[0076] Preferably, the lifting drive device of the basket connecting member also includes a tensioning device, which includes an adjusting plate 45, a first tensioning sprocket 46 whose wheel body is meshed with the chain and whose central axis is fixedly connected to the adjusting plate, a second tensioning wheel 47 whose wheel body is meshed with the chain and whose central axis is fixedly connected to the lifting well, and an adjusting shaft 49 whose one end is fixedly connected to the adjusting plate and the other end is threadedly connected to the fixed plate 48, and the fixed plate is fixedly arranged on the surface of the lifting well.

[0077] The setting of the tensioning device makes it convenient for the operator to adjust the tightness of the sprocket.

[0078] The adjustment plate is located on the outer side of the lifting well, and the main shaft of the first tensioning sprocket passes through the lifting well and is fixed to the adjustment plate. A guide hole can be provided on the surface of the adjustment plate, and a pin on the surface of the lifting well is located in the guide hole to guide the adjustment plate.

[0079] The adjustment shaft is threaded onto the fixed plate, with its end fixedly attached to the adjustment plate. To adjust the chain tension, the operator rotates the adjustment shaft to move the adjustment plate, which in turn moves the first tensioning sprocket. Because the first and second tensioning sprockets are staggered, the chain gradually tightens as the first tensioning sprocket moves.

[0080] The lifting drive module is used to drive the lifting shaft to lift and lower, so that the bottom end of the lifting shaft can be lifted to just above the basket so that the basket connector can be connected to the basket. It is a one-dimensional linear displacement drive device, preferably an electric cylinder.

[0081] The fixed frame is used to install the lifting drive module, and it is also used to connect other displacement modules to form a three-dimensional displacement mechanism, thereby driving the lifting shaft and shovel assembly to move to the predetermined area and operate the basket in the area.

[0082] In this embodiment, the fixed frame is a frame-like structure, its bottom end secured to the top plate of the mounting housing via its base plate and two L-shaped brackets 12. The lifting module's body is fixed to the front plate of the fixed frame, its output end connected to a lever 13. A guide hole 14 is vertically defined in the base plate of the fixed frame to facilitate the lever's vertical movement. The lever's end is connected to the lifting shaft to drive the shaft vertically upward and downward.

[0083] The shovel assembly, used to retrieve the pallet from the basket, contains a shovel and a shovel displacement drive assembly that drives the shovel. This assembly drives the shovel along the primary guide rails 15 within the mounting housing, allowing the shovel to extend from the end of the housing and enter the hoistway through the pallet access opening at the bottom of the hoistway, thereby retrieving the pallet from the hoistway.

[0084] During operation, the basket connector in the hoist shaft, driven by the basket connector lifting drive, rises, moving the basket 16 to the desired position. Next, the shovel, driven by the shovel displacement drive assembly, extends from the opening at the end of the mounting shell and through the panel rack inlet and into the hoist shaft, where it is positioned directly below the panel rack. The basket is then lowered slightly, allowing the panel to rest on the shovel. The shovel, driven by the shovel displacement drive assembly, then transports the panel from the basket into the mounting shell and out through the opening at the other end, allowing subsequent operation by an operator or robot.

[0085] The shovel displacement drive assembly can be a rack-and-pinion displacement drive device, or a displacement device such as an electric cylinder, pneumatic cylinder, or oil cylinder. In this embodiment, the shovel displacement drive assembly is a two-stage displacement drive mechanism. Specifically, the shovel drive assembly includes a primary slide 17 that can slide along the primary guide rail within the mounting housing; a primary linear displacement drive mechanism that is fixedly connected to the mounting housing and can drive the primary slide forward and backward along the primary guide rail within the mounting housing; a secondary slide 19 that can slide along the secondary guide rail 18 on the surface of the primary slide; and a secondary linear displacement drive mechanism that is fixedly connected to the primary slide and can drive the secondary slide forward and backward.

[0086] The first-stage linear displacement drive mechanism includes a first-stage drive motor 20 fixedly connected to the body and the top plate of the mounting shell. The output shaft of the first-stage drive motor is connected to the first-stage gear 22 through a synchronous belt transmission device 21. The first-stage gear is rotatably connected to the mounting plate 23 on the mounting shell. The first-stage gear is also engaged with the first-stage rack 24 on the first-stage skateboard, thereby driving the first-stage rack and the first-stage skateboard to move along the first-stage guide rail on the mounting shell.

[0087] Similarly, the secondary linear displacement drive mechanism includes a secondary drive motor 26, which is fixedly connected to the primary slide via a motor mounting bracket 25. The output shaft of the secondary drive motor is connected to a secondary gear 27, which meshes with a secondary rack 44 on the secondary slide, thereby driving the secondary slide along the secondary guide rail on the surface of the primary slide. The shovel is connected to the front end of the secondary slide.

[0088] The setting of the secondary displacement drive mechanism increases the stroke of the shovel displacement drive assembly while reducing its overall length, making it easier to connect it with components such as the lifting shaft.

[0089] Preferably, the fixing frame is also provided with a pipette assembly 28 for sucking the sample tube.

[0090] The arrangement of the pipette assembly is used to implement the operation of a single sample tube, thereby further improving the versatility of the multifunctional basket lifting mechanism.

[0091] The straw assembly includes a straw 29 and a straw lifting mechanism 30 for driving the straw to rise and fall. The body of the straw lifting mechanism is fixedly mounted on the bottom plate of the fixing frame.

Combined with the lift drive module, this mechanism forms a three-dimensional displacement mechanism, driving the lift shaft to a predetermined position above the refrigerated container, allowing the basket to be retrieved from the container. Compared to existing sample storage devices, this multifunctional basket lift assembly combines basket lifting and rack retrieval functions, offering greater integration, more flexible operation, and lower overall equipment costs.

[0097] Among them, the transverse displacement driving device and the longitudinal displacement driving device are both one-dimensional displacement driving mechanisms, preferably electric cylinders.
