Abstract

The application discloses a pipetting workstation track system and a pipetting workstation, which comprise an experiment table top, a long strip plate and a positioning module. A plurality of long strip plates are arranged in parallel and at intervals on the experiment table top and are connected to the experiment table top through sliding. The experiment table top is detachably connected with the positioning module on the rear side of each long strip plate. The long strip plate is provided with a positioning structure matched with the positioning module. The positioning module is arranged to be capable of being engaged with or separated from the positioning structure on the adjacent long strip plate, so that the long strip plate is positioned on the experiment table top in the engaged state and cannot be moved without the pulling force, and the long strip plate can be moved in the pulling mode when the pulling force is applied. The long strip plate is positioned through the positioning module, so that the accurate positioning of the column of functional modules on the experiment table top is ensured. Meanwhile, the long strip plate cannot be moved after being positioned, so that the movement of the column of functional modules caused by the vibration of the equipment during the experiment is prevented, and the damage of the equipment is avoided.

Description

Technical Field

[0001] This invention relates to the field of automated liquid handling technology, and in particular to a pipetting workstation track system and a pipetting workstation. Background Technology

[0002] A fully automated pipetting workstation is an automated liquid handling platform system that can replace traditional pipetting tools, automatically performing high-precision liquid handling tasks such as gradient dilution, pipetting, and liquid merging. It can also be used in conjunction with analytical instruments to achieve efficient and accurate detection of target analytes. The fully automated operation of the workstation not only frees laboratory personnel from complex experimental procedures, effectively reducing human error, improving experimental repeatability, and lowering costs, but also allows for process control and traceability. It can be widely used in bioengineering, DNA plasmid purification, drug screening, ELISA reactions, PCR pretreatment, DNA sequencing processing, clinical laboratory sample processing, and high-throughput sample analysis in blood bank systems.

[0003] Existing pipetting workstations often have workbenches that can accommodate various functional modules, such as pipette tip holders, plate consumable holders, oscillation modules, magnetic rack modules, and cooling modules. When many modules are placed on the workbench, some are located inside the equipment, away from the access door. This forces operators to extend their arms further into the equipment, causing inconvenience and potential safety hazards. Furthermore, electrically charged modules are typically fixed to the workbench; for example, an oscillation module will oscillate all modules on the workbench during operation, but some modules do not require oscillation. This results in poor versatility and operational flexibility, making it unsuitable for diverse experimental needs.

[0004] Therefore, there is an urgent need for a pipetting workstation track system and a pipetting workstation to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention aims to solve the aforementioned technical problems. Specifically, it addresses the issue that existing workstations often have numerous functional modules on their workbench, with some modules located inside the equipment far from the "equipment door." This forces operators to extend their arms further into the equipment during operation, causing inconvenience and potential safety hazards. Furthermore, electrically charged modules, such as oscillation modules, are typically fixed to the workbench. Oscillation affects all modules on the workbench, but some modules do not require oscillation. This results in poor versatility and operational flexibility, making it unsuitable for diverse experimental needs.

[0006] To this end, in a first aspect, the present invention provides a pipetting workstation track system, comprising a worktable, elongated plates, and a positioning module. Multiple elongated plates are slidably connected to the worktable, arranged side-by-side at intervals, so that the elongated plates can be extended outwards from the operating door of the pipetting workstation by a pull-out mechanism. Various functional modules are mounted on the elongated plates. The positioning module is detachably and fixedly connected to the worktable on the rear side of each elongated plate. The elongated plates are provided with positioning structures that cooperate with the positioning modules. The positioning modules are configured to engage or disengage with positioning structures on adjacent elongated plates, so that in the engaged state, the elongated plates are positioned on the worktable, preventing movement without a pulling force, while under a pulling force, they can disengage to allow the elongated plates to move by a pull-out mechanism.

[0007] In a specific embodiment of the above-mentioned pipetting workstation track system, the positioning module includes a limiting post and a ball plunger. The limiting post is detachably fixed to the experimental platform on the rear side of the long plate. The ball plunger is embedded at the top of the limiting post, and the ball head of the ball plunger extends above the limiting post. A slot is provided at the bottom of the rear end of the long plate corresponding to the limiting post to engage with the ball head to form a positioning structure. When the long plate is not pulled out, the ball head of the ball plunger is engaged in the slot to position the long plate.

[0008] In a specific embodiment of the above-mentioned pipetting workstation track system, the pipetting workstation track system further includes a damping limiting module that is the same number as and corresponds one-to-one with the long strips. The damping limiting module is installed on the experimental platform on the rear side of the long strip. The middle part of the rear end of the long strip is provided with a damping engagement structure that cooperates with the damping limiting module. When the long strip is in the unpulled state, the damping limiting module engages with the damping engagement structure to generate pressure on the long strip to form a damping force that restricts movement.

[0009] In a specific embodiment of the above-mentioned pipetting workstation track system, there are two positioning modules, which are respectively arranged on both sides of the damping limiting module. The number of positioning structures is the same as the number of positioning modules, and they are respectively arranged on both sides of the damping engagement structure.

[0010] In a specific embodiment of the above-mentioned pipetting workstation track system, the damping limiting module includes a damping column, a first spring, and a fixed column. The top of the damping column extends outward to form a limiting plate, and the bottom of the damping column is inserted into the experimental platform and can move up and down relative to it. The top of the damping column has an installation groove, and the fixed column is inserted into the installation groove and passes through the damping column to be fixedly connected to the experimental platform. The first spring is sleeved on the outside of the fixed column and is in a compressed state by the squeezing action of the fixed column. The first spring applies downward pressure to the damping column to form a damping force that moves the damping column upward. The damping engagement structure is a U-shaped latch located at the middle of the rear end of the long strip and cooperating with the damping column. The edge of the U-shaped latch is provided with a U-shaped groove. When the long strip is in the unpulled state, the damping column is inserted into the U-shaped latch and the limiting plate is located in the U-shaped groove to form an engagement to generate pressure on the long strip and form a damping force that restricts movement.

[0011] In a specific embodiment of the above-mentioned pipetting workstation track system, the pipetting workstation track system further includes a quick-connect connector for conducting electricity to the energized functional module. The quick-connect connector includes a male plug and a female plug. The male plug is detachably and fixedly connected to the rear end of a long strip plate for installing the energized functional module. The female plug is installed on the experimental platform on the rear side of the long strip plate and aligned with the male plug, so that when the long strip plate is in an unpulled state, the male plug and the female plug are connected to achieve conductivity.

[0012] In a specific embodiment of the above-mentioned pipetting workstation track system, the bottom of the long strip plate is slidably connected to the experimental table surface through a guide rail assembly. The guide rail assembly includes two guide rails arranged side by side at intervals. Each guide rail includes multiple guide rail strips arranged at intervals along the pulling direction. The guide rail strips are detachably and fixedly connected to the experimental table surface. The bottom of the long strip plate is provided with a sliding groove that cooperates with the guide rail and is open at both ends. The two ends of the guide rail strips are respectively provided with guide tapers to guide the alignment when the sliding groove of the long strip plate aligns with the guide rail strip.

[0013] In a specific embodiment of the above-mentioned pipetting workstation track system, support bars are fixed at both ends of the bottom of the long strip plate. The bottom end of the support bar extends to the bottom of the long strip plate and fits against the experimental table surface. The support bar is made of a material with self-lubricating properties.

[0014] In a specific embodiment of the above-mentioned pipetting workstation track system, a limiting block is fixed at the middle part of the bottom of the long strip plate near the rear end, and a locking block that cooperates with the limiting block is fixed on the experimental platform on the front side of the long strip plate to limit the pulling displacement of the long strip plate.

[0015] In a second aspect, the present invention also provides a pipetting workstation, including a pipetting workstation track system as described in any one of the first aspects.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The long strip is designed as a pull-out mechanism. By placing the functional modules on the strip, it can be pulled out from the operating door of the pipetting workstation. This reduces the need for operators to extend their arms excessively into the workstation during operation, simplifying operation and minimizing safety hazards. During the retraction process, the long strip is positioned using a positioning module to ensure accurate placement of the functional modules on the experimental platform. This also ensures that the strip remains stationary after it is in place, preventing damage to the equipment caused by vibrations during experiments.

[0017] 2. By setting a damping limit module, the limit plate on the damping column is inserted into the U-shaped slot and the first spring applies pressure to the long plate to form a damping force for the movement of the long plate. This adds an extra mechanical safety to the positioning of the long plate, preventing the vibration of the equipment during the experiment from causing the movement of this row of functional modules and resulting in equipment damage.

[0018] 3. By incorporating quick-connect plugs at corresponding locations on the elongated plate where the live functional modules are installed, this design overcomes the limitation of existing pipetting workstations where live modules can only be fixed to the experimental tabletop within the equipment, and also addresses the issue of live modules being restricted to the inner or left / right sides of the equipment. The structure of this application allows the live modules to be fixed anywhere on the equipment. Furthermore, the live modules mounted on the elongated plate can be pulled out of the experimental tabletop along with the plate, allowing customers to freely arrange the number and position of live modules. This increases the flexibility and versatility of the pipetting workstation, eliminating the need to modify the circuit wiring and installation structure based on different customers' requirements for tabletop functional modules, thus adapting to diverse experimental needs.

[0019] 4. Each guide rail is divided into multiple guide rail strips. This reduces the difficulty of processing the entire guide rail. Distributing the multiple guide rail strips at intervals reduces the amount of material used in the entire guide rail, which helps to reduce costs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the system or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the use of terms such as "first" and "second" to define components is merely for the convenience of distinguishing the aforementioned components. Unless otherwise stated, these terms have no special meaning and should not be construed as indicating or implying relative importance.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] This invention relates to the field of automated liquid handling technology, and in particular to a pipetting workstation track system and a pipetting workstation, comprising a worktable, elongated plates, and positioning modules. Multiple elongated plates are slidably connected to the worktable, arranged side-by-side at intervals along a transverse direction, allowing the plates to extend outwards from the operating door of the pipetting workstation via a pull-out mechanism. Various functional modules are mounted on the elongated plates. A positioning module is detachably and fixedly connected to the worktable on the rear side of each elongated plate. The elongated plates have positioning structures that cooperate with the positioning modules. The positioning modules are configured to engage or disengage with positioning structures on adjacent elongated plates. In the engaged state, the elongated plate is positioned on the worktable, preventing movement without pulling force, while under pulling force, it can disengage and move by pulling. A pull handle is fixed to the top front end of each elongated plate. This invention features a pull-out design for the elongated plate. By placing the functional modules on the plate, it can be pulled out from the operating door of the pipetting workstation. This reduces the need for operators to extend their arms excessively into the workstation during operation, simplifying the process and minimizing safety hazards. During the retraction process, the elongated plate is positioned using a positioning module, ensuring accurate placement of the functional modules on the experimental platform. This also prevents the plate from shifting after it has been positioned, thus preventing damage to the equipment caused by vibrations during the experiment.

[0026] The following is a detailed description of the pipetting workstation track system and pipetting workstation provided in the embodiments of the present invention, with reference to the accompanying drawings.

[0027] See Figure 1-21 This invention provides a pipetting workstation track system, including a workbench, elongated plates 2, and positioning modules 6. Multiple elongated plates 2 are slidably connected to the workbench, arranged side-by-side at intervals along a transverse direction, allowing the plates 2 to extend outwards from the operating door of the pipetting workstation via a pull-out mechanism. Various functional modules 3 are mounted on the elongated plates 2. A positioning module 6 is detachably and fixedly connected to the workbench surface on the rear side of each elongated plate 2. The elongated plates 2 have positioning structures that cooperate with the positioning modules 6. The positioning modules 6 are configured to engage or disengage with the positioning structures on adjacent elongated plates 2. In the engaged state, the elongated plate 2 is positioned on the workbench surface, preventing movement without pulling force, while under pulling force, it can disengage to allow for pull-out movement. A pull handle 15 is fixed to the top front end of each elongated plate 2.

[0028] In the above embodiments, the functional module 3 can be flexibly configured according to actual use, such as a pipette tip holder, a perforated plate consumable holder, an oscillation module, a magnetic rack module, a cooling module, etc. By placing the functional module 3 on the long strip plate 2, the long strip plate 2 can be pulled out from the operating door of the pipetting workstation by a pull-out method, so that the experimenter's arm does not need to penetrate too deeply into the pipetting workstation during operation, which facilitates operation and reduces safety hazards.

[0029] In the above embodiments, preferably, see [reference needed]. Figure 3 , Figure 5 , Figure 9 and Figure 16-17 The positioning module 6 includes a limiting post 602 and a ball-head plunger 601. The limiting post 602 is detachably fixed to the experimental platform on the rear side of the long plate 2. The ball-head plunger 601 is embedded in the top of the limiting post 602, and the ball head of the ball-head plunger 601 extends above the limiting post 602. A slot 14 is provided at the bottom of the rear end of the long plate 2 corresponding to the limiting post 602 to engage with the ball head, forming a positioning structure. When the long plate 2 is not pulled out, the ball head of the ball-head plunger 601 is locked in the slot 14 to position the long plate 2. Specifically, a U-shaped positioning port is provided at the bottom of the rear end of the long plate 2 for inserting the limiting post 602. The slot 14 is set on the bottom wall of the long plate 2 inside the U-shaped positioning port to ensure that the ball head of the ball-head plunger 601 can be inserted into the slot 14 while the limiting post 602 is inserted into the U-shaped positioning port.

[0030] Because the ball head of the spherical plunger can extend and retract vertically, applying sufficient pulling force to the long plate 2 will compress the ball head, causing it to retract and disengage from the slot 14, allowing for a pull-out operation. When the long plate 2 needs to be pushed back into place, the ball head can re-engage in the slot 14 under the pushing force, achieving precise positioning of the long plate 2. This, in turn, ensures the precise positioning of the functional modules 3 installed on the long plate 2, guaranteeing the smooth operation of subsequent pipetting workstation operations. Simultaneously, the engagement of the ball head with the slot 14 ensures that the long plate 2 will not move after it is in place, preventing equipment vibration during the experiment from causing movement of this row of functional modules 3 and resulting in equipment damage.

[0031] In the above embodiments, preferably, see [reference needed]. Figure 3 , Figure 5 , Figure 9-10 and Figure 13-14The pipetting workstation track system also includes damping limiting modules 5, which are the same number as and correspond one-to-one with the long strip plate 2. The damping limiting modules 5 are installed on the experimental platform behind the long strip plate 2. The middle part of the rear end of the long strip plate 2 is provided with a damping engagement structure that cooperates with the damping limiting modules 5. When the long strip plate 2 is in the unpulled state, the damping limiting modules 5 engage with the damping engagement structure to generate pressure on the long strip plate 2 to form a damping force that restricts movement. There are two positioning modules 6, which are respectively set on both sides of the damping limiting modules 5. The number of positioning structures is the same as the number of positioning modules 6, which are respectively set on both sides of the damping engagement structure.

[0032] In the above embodiment, preferably, the damping limiting module 5 includes a damping column 501, a first spring 503 and a fixing column 502. The top end of the damping column 501 extends outward to form a limiting disk 5011. The bottom of the damping column 501 is inserted into the experimental table and can move up and down relative to it. The top end of the damping column 501 is provided with an installation groove. The fixing column 502 is inserted into the installation groove and passes through the damping column 501 and is fixedly connected to the experimental table. The first spring 503 is sleeved on the outside of the fixing column 502 and is in a compressed state by the squeezing action of the fixing column 502. The first spring 503 applies downward pressure to the damping column 501 to form a damping force for the damping column 501 to move upward. The damping engagement structure is a U-shaped latch 12 located in the middle of the rear end of the long strip plate 2 and cooperating with the damping column 501. The edge of the U-shaped latch 12 is provided with a U-shaped groove 141201. When the long strip plate 2 is in the unpulled state, the damping column 501 is inserted into the U-shaped latch 12 and the limiting plate 5011 is located in the U-shaped groove 141201 to form an engagement to generate pressure on the long strip plate 2 and form a damping force to restrict movement.

[0033] Specifically, a first mounting hole 16 is provided on the experimental platform at the rear of the long strip 2. The first mounting hole 16 is a stepped hole, with the upper diameter larger than the lower diameter. The bottom of the damping column 501 is inserted into the larger diameter of the first mounting hole 16 and can move up and down relative to it. The bottom end of the damping column 501 is in contact with the first groove under the elastic force of the first spring 503. The fixing column 502 can be a screw, which is threaded into the smaller diameter hole in the first mounting hole 16. The screw nut presses the first spring 503, keeping it in a compressed state, thereby realizing the detachable installation of the damping limiting module 5. By disassembling the fixing column 502, the damping limiting module 5 can be completely removed or fixed on the experimental platform. The fixing method is simple and convenient.

[0034] By setting the damping limit module 5, the limit plate 5011 on the damping column 501 is inserted into the U-shaped slot 141201 and applies pressure to the long plate 2 through the first spring 503 to form a damping force for the movement of the long plate 2, thereby adding a mechanical safety to the positioning of the long plate 2 and preventing the movement of this row of functional modules 3 caused by the vibration of the equipment during the experiment, which would lead to equipment damage.

[0035] In the above embodiments, preferably, see [reference needed]. Figure 1-4 and Figure 21 The pipetting workstation track system also includes quick-connect fittings for conducting electricity to the energized functional module 3. The quick-connect fittings include a male plug 8 and a female plug 4. The male plug 8 is detachably and fixedly connected to the top rear end of the elongated plate 2 used to mount the energized functional module 3. The female plug 4 is mounted on the experimental platform behind the elongated plate 2 and aligned with the male plug 8, so that when the elongated plate 2 is in the unretracted state, the male plug 8 and female plug 4 are inserted to achieve conductivity. The male plug is connected to the energized functional module via a wire, which can be installed at the bottom of the elongated plate, with the wire length set according to the position of the energized functional module.

[0036] Specifically, the male plug 8 includes a male plug 802 and a first bracket 801. The first bracket 801 is detachably fixed to the top of the rear end of the long strip 2. The male plug 802 is fixed to the first bracket 801. Guide sleeves 803 are respectively provided on the first bracket 801 on both sides of the male plug 802. The female plug 4 includes a female plug 402 and a second bracket 401. The second bracket 401 is detachably fixed to the experimental table surface. The female plug 402 is fixed to the second bracket 401. Guide posts 403 that cooperate with the guide sleeves 803 are respectively fixed on the second bracket 401 on both sides of the female plug 402. Before the male plug 802 and the female plug 402 are inserted, the guide posts 403 are pre-inserted into the guide sleeves 803 for guiding and limiting, so as to ensure that the male plug 802 and the female plug 402 are aligned and smoothly inserted. For example, the quick-connect connector can be an HMD-012-MC aviation plug.

[0037] By incorporating quick-connect plugs at corresponding locations on the elongated plate where the live functional modules are installed, this design overcomes the limitation of existing pipetting workstations where live modules can only be fixed to the experimental platform inside the equipment, and also addresses the issue of live modules being restricted to the inner or left / right sides of the equipment. The structure of this application allows the live modules to be fixed anywhere on the equipment. Furthermore, the live modules mounted on the elongated plate can be pulled out of the experimental platform along with the plate, allowing customers to freely arrange the number and position of live modules. This increases the flexibility and versatility of the pipetting workstation, eliminating the need to modify the circuit wiring and installation structure based on different customers' requirements for different platform functional modules, thus adapting to diverse experimental needs.

[0038] In the above embodiments, preferably, see [reference needed]. Figure 3-4 , Figure 6-7 The bottom of the long strip 2 is slidably connected to the experimental table surface through a guide rail assembly. The guide rail assembly includes two guide rails arranged side by side at intervals. Each guide rail includes multiple guide rail strips 7 arranged at intervals along the pulling direction. The guide rail strips 7 are detachably and fixedly connected to the experimental table surface. The bottom of the long strip 2 is provided with a sliding groove 10 that cooperates with the guide rail and is open at both ends. The two ends of the guide rail strips 7 are respectively provided with guide tapers to guide the alignment when the sliding grooves 10 of the long strip 2 are connected to the guide rail strips 7.

[0039] Specifically, see Figure 8 The guide rail 7 has a T-shaped cross-section. The slide groove 10 has an inverted T-shaped cross-section that mates with the guide rail 7. The guide rail 7, inserted into the slide groove 10, restricts the movement of the long plate 2, allowing it to slide only along the direction of the guide rail 7, thus enabling the long plate 2 to be pulled out. The rear end of the slide groove 10 is connected to the U-shaped positioning port.

[0040] In the above embodiment, each guide rail is divided into multiple guide rail strips 7, which reduces the difficulty of processing the entire guide rail. Distributing the multiple guide rail strips 7 at intervals reduces the amount of material used in the entire guide rail, which helps to reduce costs. The guide rail strip 7 near the operating door is longer than the guide rail strip 7 at other locations. This is because the long strip 2 needs to stop at this position for the staff to operate the functional module 3, ensuring the overall stability of the long strip 2.

[0041] In the above embodiments, preferably, see [reference needed]. Figure 11-12 Support strips 9 are fixed at both ends of the bottom of the long strip 2. The bottom end of the support strip 9 extends to the bottom of the long strip 2 and fits against the experimental table surface. The support strip is made of a material with self-lubricating properties, for example, POM material, which has self-lubricating function.

[0042] Specifically, the slide 10 is positioned between two support bars 9. The support bars 9 remain in contact with the experimental platform during the pulling process of the long plate 2 to support the long plate 2, ensuring the overall balance of the long plate 2. This reduces the machining accuracy required for the top surface of the guide rail and the inner top wall of the slide 10. It is only necessary to ensure that the side wall of the slide 10 cooperates with the side wall of the guide rail to achieve the pulling and sliding, thus reducing the overall manufacturing difficulty.

[0043] In the above implementation, preferably, see [reference needed]. Figure 15 and Figures 19-20 A limiting block 11 is fixed at the middle part of the bottom of the long strip plate 2 near the rear end, and a locking block 13 that cooperates with the limiting block 11 is fixed on the experimental table surface on the front side of the long strip plate 2 to limit the pulling displacement of the long strip plate 2.

[0044] Specifically, the middle part of the long strip plate 2 is provided with a strip-shaped groove into which the locking block 13 can be inserted. The limiting block 11 is fixed in the strip-shaped groove. When the long strip plate 2 is placed on the experimental table, the locking block 13 is inserted into the strip-shaped groove. As the long strip plate 2 is pulled out, the limiting block 11 is blocked by the locking block 13 and cannot move further towards the operating door, thus playing a limiting role. This prevents the experimental personnel from using force to completely pull the long strip plate 2 out of the equipment, causing equipment damage and personnel injury.

[0045] Bismuth workstations are used for a wide variety of biochemical experiments, and each customer requires a different work surface, while even the same customer may have different work surface needs. Based on these considerations, the work surface modules in this application are designed with consistent dimensions, and multiple sets of mounting holes are provided on the work surface to accommodate different experimental combinations. In this application, as... Figure 3 As shown, the experimental platform near the rear end has multiple first mounting holes 16 arranged laterally for mounting the positioning module 6 and the damping limiting module 5. Each long strip 2 has at least three corresponding first mounting holes 16 on its rear side. The first mounting hole 16 in the middle is used to mount the damping column 501, and the first mounting holes 16 on both sides are used to mount the limiting column 602. The experimental platform in front of the first mounting holes 16 has multiple rows of second mounting holes 17 arranged laterally. Each group of second mounting holes 17 includes multiple second mounting holes 17 arranged along the pulling direction. Multiple guide rails 7 are detachably fixed to some of the second mounting holes 17 by screws. The experimental platform behind the first mounting holes 16 has multiple third mounting holes 18 arranged laterally for mounting the female plug 4. The second bracket 401 in the female plug 4 is detachably fixed by screws threadedly connected to two of the third mounting holes 18.

[0046] The distribution design of the first mounting hole 16, the second mounting hole 17, and the third mounting hole 18 allows multiple long strips 2 to be installed on the experimental platform, thereby enabling the installation of multiple rows and columns of functional modules 3.

Claims

1. A pipetting workstation track system, characterized in that, The device includes an experimental platform, long strips, and positioning modules. Multiple long strips are slidably connected to the experimental platform, spaced apart side-by-side, allowing them to extend outwards from the operating door of the pipetting workstation via a pull-out mechanism. Various functional modules are mounted on the long strips. The positioning module is detachably and fixedly connected to the experimental platform on the rear side of each long strip. Each long strip has a positioning structure that cooperates with the positioning module. The positioning module is configured to engage or disengage with the positioning structure on adjacent long strips. In the engaged state, the long strip is positioned on the experimental platform, preventing movement without a pulling force, while under a pulling force, it disengages, allowing the long strip to be moved by a pull-out mechanism.

2. The pipetting workstation track system according to claim 1, characterized in that, The positioning module includes a limiting post and a ball-head plunger. The limiting post is detachably fixed to the experimental platform on the rear side of the long strip. The ball-head plunger is embedded at the top of the limiting post, and the ball head of the ball-head plunger extends above the limiting post. A slot is provided at the bottom of the rear end of the long strip corresponding to the limiting post to engage with the ball head to form a positioning structure. When the long strip is not pulled out, the ball head of the ball-head plunger is engaged in the slot to position the long strip.

3. The pipetting workstation track system according to claim 1, characterized in that, The pipetting workstation track system also includes damping limiting modules that are the same number as and correspond one-to-one with the long strips. The damping limiting modules are installed on the experimental platform on the rear side of the long strips. The middle part of the rear end of the long strips is provided with a damping engagement structure that cooperates with the damping limiting modules. When the long strips are in the unpulled state, the damping limiting modules engage with the damping engagement structure to generate pressure on the long strips to form a damping force that restricts movement.

4. The pipetting workstation track system according to claim 3, characterized in that, The number of positioning modules is two, and they are respectively arranged on both sides of the damping limiting module. The number of positioning structures is the same as the number of positioning modules, and they are respectively arranged on both sides of the damping engagement structure.

5. The pipetting workstation track system according to claim 3, characterized in that, The damping limiting module includes a damping column, a first spring, and a fixed column. The top of the damping column extends outward to form a limiting plate. The bottom of the damping column is inserted into the experimental platform and can move up and down relative to it. The top of the damping column has an installation groove. The fixed column is inserted into the installation groove and passes through the damping column to be fixedly connected to the experimental platform. The first spring is sleeved on the outside of the fixed column and is in a compressed state by the squeezing action of the fixed column. The first spring applies downward pressure to the damping column to form a damping force that moves the damping column upward. The damping engagement structure is a U-shaped latch located at the middle of the rear end of the long strip and cooperating with the damping column. The edge of the U-shaped latch is provided with a U-shaped groove. When the long strip is in the unpulled state, the damping column is inserted into the U-shaped latch and the limiting plate is located in the U-shaped groove to form an engagement to generate pressure on the long strip and form a damping force that restricts movement.
