Description

Technical Field

[0001] This utility model relates to the field of biological sample consumables processing technology, and in particular to an automatic biological sample consumables processing device. Background Technology

[0002] Plastic consumables for biological experiments, also known as biological consumables, refer to the production and processing equipment applicable to the biological consumables industry. They mainly include products such as metrology, quantitative consumables, milk powder consumables, molecular biology consumables, culture consumables, testing services, outsourced experiments, sample preservation, sample processing, filtration, chromatography, general laboratory consumables, books and software, synthesis and preparation products, and experimental containers. Pipette tips, EP tubes, and multi-well plates are used in the largest quantities.

[0003] Since biological consumables are typically made of plastic, liquid residue can remain during experiments, especially when using pipette tips, leading to inaccurate pipetting. To address this, biological consumables undergo a siliconization process, where a siliconized layer is deposited on the surface to achieve a smooth finish and reduce liquid residue.

[0004] The existing silanization method usually involves putting biological consumables into a plastic bucket, pouring in silanizing liquid, and manually stirring to achieve silanization. After silanization, the biological consumables need to be taken out, drained, and then dried. This process is inefficient, and the silanizing reagents are volatile and harmful to the human body.

[0005] Therefore, existing biological sample processing devices suffer from low processing efficiency. Summary of the Invention

[0006] This utility model provides an automatic biological sample consumable processing device, which solves the technical problem of low consumable processing efficiency in existing biological sample consumable processing devices.

[0008] An automated biological sample consumable processing device includes a processing box;

[0009] The carrier box is used to carry consumables;

[0010] A drive assembly that drives the carrier box to rotate within the processing box;

[0011] A drying assembly is disposed inside the processing chamber, and the drying assembly dries the consumables inside the carrier box;

[0012] and a moving component, wherein the moving component drives the carrier box to move within the processing box via the driving component;

[0013] The processing chamber is filled with silicide liquid, the drying component is located above the surface of the silicide liquid, and the moving component drives the carrier box to enter or leave the silicide liquid through the driving component.

[0014] Preferably, the drive assembly includes a frame, the moving assembly includes a lead screw rotatably connected to the frame, the processing box is provided with a screw hole that mates with the lead screw, the frame is also provided with a guide post, and the processing box is provided with a guide hole that mates with the guide post.

[0015] Preferably, the upper end of the processing box is provided with a shoulder ring, the shoulder ring and the processing box are integral structures, and a support rib is provided between the shoulder ring and the side wall of the processing box, the support rib being located on the lower side of the shoulder ring.

[0016] Preferably, there are at least two guide posts, which are evenly arranged around the circumference of the frame. The guide holes are located on the shoulder of the frame, and each guide post is engaged with an independent guide hole. The frame is also provided with a first drive motor that drives the lead screw to rotate.

[0017] Preferably, the drive assembly further includes a second drive motor mounted on the frame, the output shaft of the second drive motor extending into the processing box, the frame having a through hole that mates with the output shaft, a rolling bearing being provided between the output shaft and the through hole, and the carrier box being mounted on the lower end of the output shaft via a mounting assembly.

[0018] Preferably, the mounting assembly includes a mounting plate fixed to the lower end of the output shaft, a cylindrical body provided on the lower side of the mounting plate, the cylindrical body protruding from the lower side of the mounting plate, a shoulder provided at the lower end of the cylindrical body, a positioning groove formed between the shoulder and the mounting plate, a connecting piece provided in the carrier box that mates with the positioning groove, and a notch provided on the shoulder that allows the connecting piece to pass through, the notch communicating with the positioning groove.

[0019] Preferably, there are two notches, which are evenly distributed around the circumference of the mounting plate, and there are two connecting pieces, which are evenly distributed around the circumference of the carrier box.

[0020] Preferably, the mounting plate is provided with a positioning post for positioning the connecting piece, the connecting piece is provided with a groove that mates with the positioning post, the mounting plate is provided with a hole that mates with the positioning post, the hole communicates with the positioning groove, the part of the positioning post that mates with the groove is hemispherical, and an elastic element that pushes the positioning post to mate with the groove is also provided between the positioning post and the mounting plate.

[0021] Preferably, the mounting plate is provided with a mounting bracket, the elastic element is a spring, the upper end of the spring is fixed to the mounting bracket, and the lower end of the spring is fixedly connected to the positioning post.

[0022] Preferably, the carrier box has liquid dispensing holes evenly distributed throughout it, and the liquid dispensing holes penetrate the carrier box so that the siliconizing liquid enters the carrier box through the liquid dispensing holes. The drying component is a fan.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] By configuring a drive assembly to rotate the carrier box, the rotation of the carrier box, when fully immersed in the silanizing solution, improves the contact performance between the consumable and the silanizing solution, resulting in higher silanization efficiency. After silanization is complete, the carrier box leaves the silanizing solution and is positioned above its surface. Then, the drive assembly rotates the carrier box again, and under centrifugal force, the silanizing solution adhering to the consumable can be quickly detached. Finally, the consumable is dried by a drying assembly. Since some of the silanizing solution on the consumable has been removed under centrifugal force, the drying efficiency of the consumable is effectively improved, thereby significantly increasing the processing efficiency of the consumable.

[0025] By setting up a moving component, the carrier box can be easily moved within the processing chamber. Different process steps are completed when the consumables are in different positions within the processing chamber. For example, when the consumables are immersed in the siliconizing solution, they are used to complete siliconization. When the consumables are removed from the siliconizing solution, they are used to complete drying. The movement of the carrier box does not require manual operation, reducing the labor intensity of the operators. Attached Figure Description

[0039] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0040] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0041] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0042] Reference Figures 1 to 6 As shown, an automated biological sample consumable processing device includes a processing box 1;

[0043] Carrier box 2, the carrier box 2 is used to carry consumables;

[0044] Drive component 3 drives the carrier box 2 to rotate within the processing box 1;

[0045] Drying component 4 is disposed inside the processing box 1, and the drying component 4 dries the consumables inside the carrier box 2;

[0046] and the moving component 5, which drives the carrier box 2 to move within the processing box 1 via the driving component 3;

[0047] The processing tank 1 is filled with silicide liquid, the drying component 4 is located above the surface of the silicide liquid, and the moving component 5 drives the carrier box 2 to enter or leave the silicide liquid through the driving component 3.

[0048] Specifically, when performing siliconization on the consumables, the consumables are first rotated in the carrier box 2, and then the moving component 5 drives the carrier box 2 to move downwards, so that the carrier box 2 is immersed in the siliconization liquid.

[0049] The drive component 3 drives the carrier box 2 located in the siliconization liquid to rotate, so that the consumables can quickly complete siliconization.

[0050] After the consumable is siliconized, the moving component 5 drives the carrier box 2 to detach from the surface of the siliconizing liquid. At this time, the carrier box 2 is located above the surface of the siliconizing liquid. The driving component 3 drives the carrier box 2 to rotate, and under the action of centrifugal force, the residual siliconizing liquid on the consumable quickly leaves the consumable.

[0051] The moving component 5 then moves the drive carrier box 2 upward. When the position of the carrier box 2 corresponds to that of the drying component 4, the drying component 4 starts working and quickly dries the consumables.

[0052] Finally, the moving component 5 moves the carrier box 2 outside the processing box 1, and the carrier box 2 is manually removed to prepare for the next consumable processing.

[0053] In some embodiments, the drive assembly 3 includes a frame 31, the moving assembly 5 includes a lead screw 51 rotatably connected to the frame 31, the processing box 1 is provided with a screw hole that mates with the lead screw 51, the frame 31 is also provided with a guide post 52, and the processing box 1 is provided with a guide hole that mates with the guide post 52. The lead screw 51 has an optical axis portion that is rotatably connected to the frame 31. The optical axis portion and the frame 31 can be an integral structure.

[0054] In some embodiments, the upper end of the processing box 1 is provided with a shoulder 11, the shoulder 11 and the processing box 1 are integral structures, and a support rib 12 is provided between the shoulder 11 and the side wall of the processing box 1, the support rib 12 being located on the lower side of the shoulder 11.

[0055] The support rib 12, the shoulder 11, and the processing box 1 are an integral structure. The support rib 12 is used to support the shoulder 11, so that the shoulder 11 and the processing box 1 have a higher connection strength.

[0056] In some embodiments, there are at least two guide posts 52, which are evenly arranged around the circumference of the frame 31. The guide hole is provided on the shoulder 11, and each guide post 52 cooperates with an independent guide hole. The frame 31 is also provided with a first drive motor 53 that drives the lead screw 51 to rotate.

[0057] The cross-sectional shape of the guide post 52 can be circular or polygonal.

[0058] Reference Figures 1 to 6 As shown, in some embodiments, the drive assembly 3 further includes a second drive motor 32 mounted on the frame 31, the output shaft 33 of the second drive motor 32 extending into the processing box 1, the frame 31 being provided with a through hole that mates with the output shaft 33, a rolling bearing being provided between the output shaft 33 and the through hole, and the carrier box 2 being mounted on the lower end of the output shaft 33 by a mounting assembly.

[0059] In some embodiments, both the first drive motor 53 and the second drive motor 32 can be fixed to the frame 31 with screws.

[0060] In some embodiments, the mounting assembly includes a mounting plate 34 fixed to the lower end of the output shaft 33. A cylindrical body 341 is provided on the lower side of the mounting plate 34. The cylindrical body 341 protrudes from the lower side of the mounting plate 34. A shoulder 342 is provided at the lower end of the cylindrical body 341. A positioning groove 343 is formed between the shoulder 342 and the mounting plate 34. The carrier box 2 is provided with a connecting piece 21 that cooperates with the positioning groove 343. The shoulder 342 is provided with a notch 3421 that allows the connecting piece 21 to pass through. The notch 3421 communicates with the positioning groove 343.

[0061] In some embodiments, there are two notches 3421, which are evenly arranged around the circumference of the mounting plate 34, and there are two connecting pieces 21, which are evenly arranged around the circumference of the carrier box 2.

[0062] In some embodiments, the connecting piece 21 and the carrier box 2 are integrally formed. The connecting piece 21 protrudes from the carrier box 2 along the diameter direction of the carrier box 2.

[0063] In some embodiments, the mounting plate 34 is provided with a positioning post 344 for positioning the connecting piece 21, the connecting piece 21 is provided with a groove 22 that mates with the positioning post 344, the mounting plate 34 is provided with a hole that mates with the positioning post 344, the hole communicates with the positioning groove 343, the portion of the positioning post 344 that mates with the groove 22 is hemispherical, and an elastic element 345 is also provided between the positioning post 344 and the mounting plate 34 to push the positioning post 344 to mate with the groove 22.

[0064] In some embodiments, the mounting plate 34 is provided with a mounting bracket 346, the elastic element 345 is a spring, the upper end of the spring is fixed to the mounting bracket 346, and the lower end of the spring is fixedly connected to the positioning post 344.

[0065] Mounting bracket 346 can be fixed to mounting plate 34 with screws.

[0066] Understandably, a positioning piece can be provided in the positioning groove 343. The positioning piece contacts the connecting piece 21 and defines the position of the connecting piece 21 within the positioning groove 343. When the drive assembly 3 drives the carrier box 2 to rotate, under the action of inertial force, the connecting piece 21 moves towards the positioning piece until it contacts the positioning piece, thereby positioning the connecting piece 21 within the positioning groove 343 and effectively preventing the connecting piece 21 from dislodging from the positioning groove 343.

[0067] When the connecting piece 21 is set, the positioning post 344 is not required.

[0068] Understandably, when the connecting piece 21 and the positioning groove 343 have a large coefficient of friction and the inertial force is insufficient to make the connecting piece 21 move automatically in the positioning groove 343, the positioning post 344 and the positioning piece may not be provided.

[0069] Understandably, when installing the carrier plate, align the connecting piece 21 with the notch 3421, then move it upwards to allow the connecting piece 21 to pass through the notch 3421 and enter the positioning groove 343. Then, rotate the carrier box 2 to displace the connecting piece 21 from the notch 3421, thus completing the installation of the carrier box 2. Removing the carrier box 2 is done in the reverse order.

[0070] Reference Figures 1 to 6As shown, it can be understood that the distance from which the positioning post 344 extends into the positioning groove 343 is determined by the spring. That is, in addition to pushing the positioning post 344 into the groove 22, the spring is also used to limit the position of the positioning post 344 to prevent the positioning post 344 from extending too far into the positioning groove 343, causing interference between the connecting piece 21 and the positioning post 344.

[0071] When the groove 22 corresponds to the positioning post 344, the elastic element 345 pushes the lower end of the positioning post 344 into the groove 22 to position the connecting piece 21.

[0072] In some embodiments, the carrier box 2 is provided with liquid dispensing holes 23, which are distributed throughout the carrier box 2. The liquid dispensing holes 23 are connected to the carrier box 2, and the siliconizing liquid enters the carrier box 2 through the liquid dispensing holes 23. The drying component 4 is a fan.

[0073] In some embodiments, the fan can be fixed to the frame 31 with screws. The fan is a common blower assembly.

[0074] In some embodiments, a heating element may be integrated into the fan to increase the temperature of the airflow output by the fan, thereby enabling the fan to achieve faster drying efficiency. The heating element may be a heating tube or a heating wire.

[0075] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0076] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0077] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
