[0048] During biochemical experiments, researchers often use microplate lifts and clamps to hold samples to avoid contamination, interference with experimental accuracy, or disruption to the researcher. Currently, existing microplate lifts and clamps often lack a lifting function or only offer a single level of lift, failing to meet the needs of many experimental scenarios.

[0049] The following embodiments of the present application provide a microplate lifting and clamping device, which solves the technical problem of how to enable the microplate lifting and clamping device to achieve two-stage lifting.

[0050] The principle and implementation of a microplate lifting and clamping device of this embodiment will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand the microplate lifting and clamping device of this embodiment without creative work.

[0051] See also Figures 1 to 7 As shown, this embodiment provides a microplate lifting and clamping device, comprising a base 1, a driving unit 2, a lifting unit 3, and a clamping unit 4. The driving unit 2 is connected to the lifting unit 3, the lifting unit 3 is connected to the clamping unit 4, and the clamping unit 4 is connected to the base 1.

[0052] Furthermore, the driving unit 2 drives the lifting unit 3 to move up and down within a first distance range, and the lifting unit 3 causes the clamping unit 4 to move up and down within a second distance range.

[0053] Please continue reading Figures 1 to 3 As shown, the drive unit 2 includes a first mounting base 21, two first electric wheels 22 and a first transmission belt 23 wrapped around the two first electric wheels 22. The two first electric wheels 22 are mounted on the first mounting base 21, and the first mounting base 21 is fixedly connected to the mechanical housing 5.

[0054] Specifically, a connection block 211 is provided on the first mounting base, and the first mounting base 21 is fixedly connected to the mechanical housing 5 via the connection block 211 .

[0055] Please continue to refer to 3 to Figure 4 As shown, a first transmission block 231 is provided on the first transmission belt 23 , and the first transmission block 231 is connected to the lifting unit 3 . The first transmission belt 23 drives the lifting unit 3 to move up and down within the first distance range through the first transmission block 231 .

[0056] by Figure 3 For example, when the first motorized wheel 22 begins to rotate, the first transmission block 231 on the first transmission belt 23 begins to move along with the first transmission belt 23. Because the first transmission block 231 is connected to the lifting unit 3, the lifting unit 3 moves synchronously. The first distance range is actually the range of movement of the first transmission block 231 on the first transmission belt 23.

[0057] Please continue reading Figures 3 and 4 As shown, the lifting unit 3 includes a second mounting base 31, two second electric wheels 32 and a second transmission belt 33 wrapped around the two second electric wheels 32, the two second electric wheels 32 are mounted on the second mounting base 31, and the second mounting base 31 is connected to the first transmission block 231.

[0058] Furthermore, a second transmission block 331 is provided on the second transmission belt 33 , and the second transmission block 331 is connected to the clamping unit 4 . The second transmission belt 33 drives the clamping unit 4 to move up and down within the second distance range through the second transmission block 331 .

[0059] by Figure 3For example, when the second motorized wheel 32 begins to rotate, the second transmission block 331 on the second transmission belt 33 begins to move along with the second transmission belt 33. Because the second transmission block 331 is connected to the lifting unit 3, the lifting unit 3 moves synchronously. The second distance range is actually the range of movement of the second transmission block 331 on the second transmission belt 33.

[0060] See also Figure 4 and Figure 5 As shown, the clamping unit 4 includes a mounting plate 41 , a clamping driver 42 and two clamping jaws 43 connected to the clamping driver 42 ; the clamping driver 42 is mounted on the mounting plate 41 , and the mounting plate 42 is connected to the second transmission block 331 .

[0061] During the clamping process, the clamping unit 4 and the lifting unit 3 can be rapidly lowered by the driving unit 2. Afterwards, the lifting unit 3 drives the clamping unit 4 to slowly descend over a small distance until the clamping jaws 43 are distributed on both sides of the sample. At this time, the clamping driver 42 drives the clamping jaws 43 to clamp, and the two clamping jaws 43 clamp the experimental sample inward to achieve the clamping of the microplate.

[0062] For further information, please refer to Figures 4 to 6 As shown, two first mounting holes 431 are provided on the clamping jaw 43 , and the clamping jaw 43 is connected to the clamping driver 42 through the two first mounting holes 431 .

[0063] For further information, please refer to Figure 5 As shown, a sliding mounting base plate 11 is provided on the base 1, and the mounting plate 41 is connected to the sliding mounting base plate 1. When the second transmission belt 33 drives the mounting plate 41 to move up and down through the second transmission block 331, the sliding mounting base plate 11 slides synchronously.

[0064] Please continue reading Figures 4 to 7 As shown, the driving unit 2 includes a limiting component 24 , and the base 1 is provided with a fixing component 12 , and the limiting component 24 forms a locking position with the fixing component 12 .

[0065] For further information, please refer to Figures 3 to 6 As shown, the limiting component 24 includes an L-shaped limiting plate, and two second mounting holes 241 are provided on the L-shaped limiting plate. The L-shaped limiting plate is fixedly connected to the mechanical housing 5 through the two second mounting holes 241 .

[0066] In some embodiments, the limiting component 24 further includes a motor and a screw. When the motor is driven, the screw drives the L-shaped limiting plate upward. Because the L-shaped limiting plate is locked with the fixing component 12, the L-shaped limiting plate cannot move upward. This creates a downward reaction force, which stabilizes the drive unit while also allowing the remaining lifting units (excluding the drive unit) and the clamping unit connected to the lifting unit to descend rapidly.

[0067] In the microplate lifting and clamping device provided herein, the drive unit 2 and the mechanical housing 5 are securely connected, thereby ensuring the stability of the drive unit 2. The drive unit 2 drives the lifting unit 3 to perform a lifting motion, enabling rapid lifting and lowering movement. Subsequently, the clamping unit 4 is moved within a second range of distances by the lifting unit 3, enabling slow movement over a short distance and within a small range, enabling the microplate lifting and clamping device to accurately clamp the desired microplate.

[0068] Therefore, the microplate lifting and clamping device provided in the present application can provide two lengths of lifting distances, that is, a two-stage lifting unit, thereby being able to meet the clamping requirements of different scenarios.

[0069] For example, in a PCR amplification experiment, the PCR plate set after being heated by the amplifier forms a vacuum negative pressure, which makes it difficult for the PCR plate to be separated from the base. At this time, if the experimenter comes into direct contact with the PCR plate and manually separates the PCR plate and the base, on the one hand, the pollutants such as aerosols generated by PCR amplification will affect the personnel, and on the other hand, the extraction plate will be damaged or contaminated, thus failing to meet the experimental requirements. At this time, the microplate lifting and clamping device provided by the above embodiment of the present application can be set on a workbench and connected to a mobile unit. The mobile unit provides X / Y axis movement and the clamping unit is lowered to a suitable height (two-stage Z-axis movement) through a driving unit and a lifting unit. At this time, the clamping claws, driven by the clamping driver, exert force inward on both sides to clamp the microplate and separate it from the base. In addition, the extraction plate can also be moved to other experimental equipment. Even if the heights of the experimental equipment are different, the microplate lifting and clamping device provided by the present application can perform precise two-stage height lifting and lowering to achieve grabbing or putting down.

[0070] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this application shall be covered by the claims of this application.
