Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a pipette fixation assembly. Background Technology

[0002] Pipettes are commonly used precision liquid handling consumables in the medical device field to achieve accurate measurement, transfer and distribution of micro-volume liquids. In automated production processes, they often need to be stored in batches in storage cabinets for use. Therefore, a stable and reliable fixing method is considered one of the key process steps.

[0003] Existing pipette fixing methods mostly use neatly arranged pipette racks. However, this arrangement can easily cause adjacent devices to come into contact with the external clamps when they pick up the target pipette. This not only interferes with the accuracy of operation but may also cause structural damage or contamination to the pipette, affecting product quality and production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that external clamping components easily collide with adjacent devices when gripping a target pipette. This invention provides a pipette fixing assembly that effectively solves the problem of collisions between the external clamping component and adjacent devices when gripping a target pipette.

[0005] To solve the above-mentioned technical problems, the present invention discloses a pipette fixing assembly, which includes a support plate; multiple sets of connecting seats, each set of connecting seats being spaced apart along a first direction, each set of connecting seats including two clamping parts, the two clamping parts being spaced apart along a second direction, and adjacent two clamping parts being staggered along the first direction; and all fixed to the support plate, the two clamping parts being used to clamp the connectors at both ends of a pipette; the first direction is perpendicular to the second direction.

[0006] By employing the above technical solution, and staggering the clamping parts on the same side of each set of connectors, the operating gap between adjacent pipettes is increased within a limited space. This effectively avoids collisions between the external clamping components and adjacent devices when gripping the target pipette, and also improves the success rate of gripping operations and the stability and reliability of the overall production process. Furthermore, setting multiple sets of connectors allows for the placement of multiple pipettes, reducing the time spent manually handling pipettes during automated production and effectively improving production efficiency.

[0007] According to another specific embodiment of the present invention, each of the clamping parts includes a base, a first clamping groove and a second clamping groove, the first clamping groove and the second clamping groove being used to clamp the connector respectively; the first clamping groove and the second clamping groove are spaced apart along the second direction, and the first clamping groove and the second clamping groove are respectively fixed to the base.

[0008] The above technical solution is adopted. Each clamping part is provided with a first clamping groove and a second clamping groove. By setting the double clamping groove structure, the two ends of the pipette connector can be clamped respectively, forming double-sided constraints, thereby effectively increasing the stability and reliability of clamping and effectively preventing the pipette from shaking or falling off during operation.

[0009] According to another specific embodiment of the present invention, the first clamping groove and the second clamping groove are spaced apart along the second direction to define a gap space between the first clamping groove and the second clamping groove. The gap space extends vertically along the first direction and has a first opening along the first direction. The gap space also has a second opening along a third direction, allowing an external clamping member to enter the gap space through the first opening and the second opening to clamp or place a pipette. Both the first clamping groove and the second clamping groove have a third opening along the third direction, which communicates with the second opening along the second direction, allowing a pipette to enter and exit the first clamping groove and the second clamping groove through the second opening. The third direction is perpendicular to both the second direction and the first direction.

[0010] Using the above technical solution, the first clamping groove and the second clamping groove are spaced apart to form an interval space. The interval space is provided with a first opening and a second opening along a first direction and a third direction, respectively. The second opening is connected to a third opening formed by the first clamping groove and the second clamping groove along the third direction. When a pipette needs to be placed, the external clamping member enters the interval space through the second opening along the third direction. The two ends of the pipette connector are placed in the first clamping groove and the second clamping groove respectively through the third opening. The external clamping member then leaves the interval space through the first opening along the first direction. When a pipette needs to be removed, the external clamping member enters the interval space through the first opening along the first direction, clamps the pipette connector, and then removes the pipette through the second opening along the third direction. The pipette connector leaves the first clamping groove and the second clamping groove through the third opening along the third direction, thereby effectively realizing the placement and removal of the pipette through the external clamping part.

[0011] According to another specific embodiment of this utility model, the base has a square structure.

[0012] According to another specific embodiment of the present invention, the first clamping groove and the second clamping groove are respectively perpendicular to the base.

[0013] By adopting the above technical solution, the first clamping groove and the second clamping groove are perpendicular to the base, which is more in line with the movement path of the external clamping component, thereby effectively improving the success rate of clamping operation and the stability and reliability of the overall production process.

[0014] According to another specific embodiment of the present invention, both the first clamping groove and the second clamping groove are U-shaped grooves.

[0015] By adopting the above technical solution, the grooves of the first clamping groove and the second clamping groove are set as U-shaped. The U-shaped groove structure can better fit the outer wall of the pipette connector structure, providing a larger contact area, thereby achieving more stable and reliable clamping.

[0016] According to another specific embodiment of the present invention, the first clamping groove includes a first upper groove wall and a first lower groove wall disposed opposite to each other, and the second clamping groove includes a second upper groove wall and a second lower groove wall disposed opposite to each other. Each of the first upper groove wall, the first lower groove wall, the second upper groove wall and the second lower groove wall is provided with an elastic clamping member, which is used to clamp the pipette.

[0017] By adopting the above technical solution, elastic clamping components are set on the upper tank wall and the lower tank wall. The flexible clamping of the pipette connector is achieved by the elastic clamping components, which can effectively improve the reliability and stability of clamping. Furthermore, by utilizing the variable characteristics of the elastic clamping components themselves, while ensuring effective clamping, it will not hinder the external clamping components from placing and removing the pipette from the clamping slot, thus effectively achieving the stability of clamping and the smoothness of operation.

[0018] According to another specific embodiment of the present invention, the elastic clamping member is a plunger.

[0019] According to another specific embodiment of the present invention, the elastic clamping member is a spring sheet.

[0020] According to another specific embodiment of the present invention, the support plate is the wall of the pipette dispensing chamber. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Pipettes are commonly used precision liquid handling consumables in the medical device field to achieve accurate measurement, transfer, and dispensing of minute amounts of liquid. Pipettes are usually single-use products, so in automated production processes, they often need to be stored in batches in storage cabinets for later use. In some existing embodiments, pipettes are often fixed by neatly arranged pipette racks. However, this arrangement can cause adjacent devices to come into contact when the external clamping device picks up the target pipette, which not only interferes with the accuracy of operation but may also cause structural damage or contamination of the pipette, affecting product quality and production efficiency.

[0033] To address this, this application provides a pipette fixing assembly, which includes multiple sets of connecting seats, each set of connecting seats being spaced apart along a first direction, and each set of connecting seats including two clamping parts, the two clamping parts being staggered along the first direction. By staggering the clamping parts, the problem of contact between the external clamping member and other adjacent devices when the external clamping member clamps the target pipette is solved.

[0034] Understandably, reference Figure 1 In this embodiment, the pipette 1 includes two connectors 2. However, those skilled in the art will understand that in other embodiments, the pipette 1 may include any number of connectors 2, such as one, three, etc., and this application does not impose any limitation on this.

[0035] Specifically, refer to Figure 1 and Figure 2 The pipette fixing assembly 100 includes a support plate 200 and multiple sets of connectors 300. Each set of connectors 300 is spaced apart along a first direction Z. Each set of connectors 300 includes two clamping parts 310. The two clamping parts 310 are spaced apart along a second direction X. Adjacent clamping parts 310 are staggered along the first direction Z. Both are fixed to the support plate 200. The two clamping parts 310 are used to clamp the connectors 2 at both ends of a pipette 1. The first direction Z is perpendicular to the second direction X.

[0036] Understandably, reference Figure 1 The aforementioned support plate 200 can be the wall of the dispensing chamber of the pipette 1, or any wall or floor of other working spaces, and this application does not limit it in this regard.

[0037] It should be noted that the distance between the two clamping parts 310 along the second direction X depends on the distance between the two connectors 2 of the pipette 1. The two clamping parts 310 are used to clamp the two connectors 2 respectively, and this application does not limit this.

[0038] Specifically, the two adjacent clamping parts 310 are staggered along the first direction Z, which can reserve operating space by staggering the positions to prevent the external clamping part 3 from touching the adjacent device when clamping the target pipette 1.

[0039] For example, refer to Figure 1 and Figure 2 The support plate 200 has a total of 4 sets of connecting seats 300. However, those skilled in the art will understand that in other embodiments, the support plate 200 may have any number of connecting seats 300, such as 3 sets, 5 sets, 8 sets, etc., and this application does not limit this number.

[0040] refer to Figure 3 Each clamping part 310 includes a base 311, a first clamping groove 312, and a second clamping groove 313, the first clamping groove 312 and the second clamping groove 313 being used to clamp the connector 2 in the pipette 1 (e.g., Figure 1 (As shown); the first clamping groove 312 and the second clamping groove 313 are spaced apart along the second direction X, and the first clamping groove 312 and the second clamping groove 313 are respectively fixed to the base 311.

[0041] Specifically, the first clamping groove 312 and the second clamping groove 313 are spaced apart, so as to clamp the two ends of the connector 2 in the pipette 1 respectively. By setting the double clamping groove structure, double-sided constraint is formed, thereby effectively increasing the stability and reliability of clamping and effectively preventing the pipette 1 from shaking or falling off during operation.

[0042] Further, refer to Figure 3 The first clamping groove 312 and the second clamping groove 313 are spaced apart along the second direction X to define a space 314 between them. The space 314 extends vertically along the first direction Z. The space 314 has a first opening 3141 along the first direction Z and a second opening 3142 along the third direction Y, so that an external clamping member 3 can enter the space 314 through the first opening 3141 and the second opening 3142 to clamp or place a pipette 1 (e.g., ...). Figure 5 (As shown); both the first clamping groove 312 and the second clamping groove 313 are provided with a third opening 315 along the third direction Y. The third opening 315 and the second opening 3142 are connected along the second direction X, so that a pipette 1 can enter and exit the first clamping groove 312 and the second clamping groove 313 through the second opening 3142. The third direction Y is perpendicular to the second direction X and the first direction Z, respectively.

[0043] For example, the base 311 has a square structure. However, those skilled in the art will understand that in other embodiments, the base 311 can be other shapes, such as cylindrical, etc., and this application does not limit it in this regard.

[0044] For example, the first clamping groove 312 and the second clamping groove 313 are respectively perpendicular to the base 311. However, those skilled in the art will understand that in other embodiments, the first clamping groove 312 and the second clamping groove 313 may form other angles with the base 311, such as acute angles or obtuse angles, as long as it is ensured that the first clamping groove 312 and the second clamping groove 313 can effectively clamp the connector 2. This application does not impose any restrictions on this.

[0045] For example, both the first clamping groove 312 and the second clamping groove 313 are U-shaped grooves. However, those skilled in the art will understand that in other embodiments, the first clamping groove 312 and the second clamping groove 313 can be grooves of other shapes, such as dovetail grooves, rectangular grooves, etc., and this application does not limit them in this regard.

[0046] Further, refer to Figure 4 The first clamping groove 312 includes a first upper groove wall 3121 and a first lower groove wall 3122 arranged opposite to each other, and the second clamping groove 313 includes a second upper groove wall 3131 and a second lower groove wall 3132 arranged opposite to each other. The first upper groove wall 3121, the first lower groove wall 3122, the second upper groove wall 3131 and the second lower groove wall 3132 are all provided with elastic clamping members, which are used to clamp the pipette 1.

[0047] It should be noted that by setting elastic clamping members on the first upper groove wall 3121, the first lower groove wall 3122, the second upper groove wall 3131, and the second lower groove wall 3132 respectively, the flexible clamping of the connector 2 in the pipette 1 can be achieved through the elastic clamping members, which can effectively improve the reliability and stability of clamping. Furthermore, by utilizing the variable characteristics of the elastic clamping members themselves, while ensuring effective clamping, it will not hinder the external clamping members 3 from placing and removing the pipette 1 from the clamping groove, thus effectively achieving the stability of clamping and the smoothness of operation.

[0048] For example, refer to Figure 3 and Figure 4The elastic clamping component is a plunger 316. A first through hole 31211 is provided in the first upper groove wall 3121, a second through hole 31221 is provided in the first lower groove wall 3122, a third through hole 31311 is provided in the second upper groove wall 3131, and a fourth through hole 31321 is provided in the second lower groove wall 3132. The plunger 316 is respectively assembled into the first through hole 31211, the second through hole 31221, the third through hole 31311, and the fourth through hole 31321, thereby achieving bidirectional constraint on the pipette 1 connector 2 in the first direction Z, effectively suppressing the displacement and loosening of the pipette 1 under vibration and other working conditions, and ensuring the stability of the clamping force through the compensation effect of the elastic element.

[0049] In some possible embodiments, the resilient clamping element is a spring.

[0050] It should be noted that the reference Figure 4 and Figure 5 The first clamping groove 312 and the second clamping groove 313 are spaced apart to form a space 314. The space 314 has a first opening 3141 and a second opening 3142 along the first direction Z and the third direction Y, respectively. The second opening 3142 is connected to a third opening 315 formed by the first clamping groove 312 and the second clamping groove 313 along the third direction Y. When it is necessary to place the pipette 1, the external clamping member 3 enters the space 314 through the second opening 3142 along the third direction Y. The two ends of the pipette 1 connector 2 are respectively placed in the first clamping groove 3141 through the third opening 315. The clamping groove 312 and the second clamping groove 313 are used. The external clamping member 3 then leaves the spacer space 314 through the first opening 3141 along the first direction Z. When it is necessary to remove the pipette 1, the external clamping member 3 enters the spacer space 314 through the first opening 3141 along the first direction Z, clamps the pipette 1 connector 2, and then removes the pipette 1 through the second opening 3142 along the third direction Y. The pipette 1 connector 2 leaves the first clamping groove 312 and the second clamping groove 313 through the third opening 315 along the third direction Y, thereby effectively realizing the placement and clamping of the pipette 1 through the external clamping part 310.

[0051] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
