The upper portion of the container 222 has a container port 2221, and a pipetting component such as a pipetting pump or a pipetting gun can be inserted into the container 222 from the container port 2221 to perform pipetting.

[0052] Since the container carrying assembly 200 is provided with a plurality of container placement portions 221, the plurality of containers 222 can be respectively positioned in the plurality of container placement portions 221 of the container carrying assembly 200, and the plurality of containers 222 can remain stable when the container carrying assembly 200 moves.

[0053] Figure 8 FIG. 1 is a perspective view of a multilayer rack body of a solvent storage device according to an embodiment of the present application; Figure 9 FIG. 2 is a front view of the multilayer rack body of the solvent storage device shown in FIG. 1. Figure 8 FIG. 3 is a side view of the multilayer rack body of the solvent storage device shown in FIG. 1.

[0054] Referring to FIGS. 1 to 3, Figure 8 and Figure 9 In some embodiments, the rack body 100 is provided with multiple layers, and the multiple layers of the rack body 100 are arranged in the longitudinal direction Z and fixedly combined or detachably combined into one body, for example, Figure 8 The embodiment is provided with three rack bodies, namely, a rack body 100a, a rack body 100b, and a rack body 100c, which are arranged in the longitudinal direction Z. The rack body 100a is provided with a container carrying assembly 200a and a container sealing assembly 500a, the rack body 100b is provided with a container carrying assembly 200b and a container sealing assembly 500b, and the rack body 100c is provided with a container carrying assembly 200c and a container sealing assembly 500c.

[0055] The openings of the accommodating cavities of the rack body 100a, the rack body 100b, and the rack body 100c are arranged on the same side, which facilitates pipetting operation on the same side. The number of layers of the rack body can be selected according to actual needs to accommodate different numbers of containers 222.

[0056] In some embodiments, when the rack body has multiple layers, the multiple layers of the rack body are connected in sequence in the vertical direction. The bottom plate of an upper rack body (for example, the rack body 100b) is supported on the top of a lower rack body (for example, the rack body 100a), and a top plate can be arranged on the top of the uppermost rack body (for example, the rack body 100c). The top plate is provided with a plurality of positioning members, which are used in limiting cooperation with a support of another container placed on the top plate. The other container can be, for example, a test tube used for containing a reagent.

[0057] Referring to FIGS. 1 to 3, Figure 3 , Figure 4 and Figure 8In the embodiment, the rack body 100 is assembled by a plurality of plate bodies. For example, the rack body 100 can include a bottom plate 110, a top plate (not shown), a back plate 130 and two side plates 120 connected between the bottom plate 110 and the top plate. The bottom plate 110, the top plate, the back plate 130 and the two side plates 120 define a containing cavity. An opening of the containing cavity is arranged on the opposite side of the back plate 130. For example, the opening can be arranged in the transverse direction X. The container carrying assembly 200 can move from the opening to the inside or outside of the containing cavity. When the container carrying assembly 200 moves to the inside of the containing cavity, a plurality of containers 222 can be stored in the containing cavity. When the container carrying assembly 200 moves to the outside of the containing cavity, the plurality of containers 222 can be easily subjected to pipetting operation. In the embodiment, the container carrying assembly 200 is connected to the rack body 100 through a first movement mechanism 300. The first movement mechanism 300 can drive the container carrying assembly 200 to move. Continue to refer to Figure 2 and Figure 3 In an implementation, the first movement mechanism 300 includes a first guide assembly and a first driving assembly. The container carrying assembly 200 is slidably connected to the first guide assembly. The first driving assembly is in transmission connection with the container carrying assembly 200, and is configured to drive the container carrying assembly 200 to move, so that the plurality of containers 222 on the container carrying assembly 200 can move to the outside of the containing cavity or to the inside of the containing cavity.

[0058] In some embodiments, the first guide assembly includes two transverse guide rails 310 arranged in parallel on the bottom plate 110 of the rack body 100. The two transverse guide rails 310 include inner ends and outer ends. The inner ends are arranged close to the back plate 130 of the rack body 100. The outer ends extend to the opening of the containing cavity. The two transverse guide rails 310 are arranged in the containing cavity in the transverse direction X, and are arranged close to the two side plates 120 respectively. The container carrying assembly 200 is slidably connected to and supported on the two transverse guide rails 310.

[0059] Continue to refer to Figure 3 In some embodiments, the first driving assembly includes a first motor 320 and a first driving rod 330 in transmission cooperation with the first motor 320. The motor can be a linear stepper motor. The linear stepper motor can drive the first driving rod 330 to move linearly along the axial direction (i.e., the X-axis direction) of the first driving rod 330. The first motor 320 is fixedly arranged relative to the rack body 100. For example, the first motor 320 can be fixed to the rack body 100 through a fixing member (such as a motor fixing seat).

[0060] The first driving rod 330 is connected with the container carrying assembly 200, and specifically, the first driving rod 330 is connected with the lower side of the container carrying assembly 200, and can drive the container carrying assembly 200 to move along the transverse direction X. Since the plurality of containers 222 and the container carrying assembly 200 are limited in position and the positions can be kept relatively stable, the plurality of containers 222 can move simultaneously with the first driving rod 330. When the first driving rod 330 drives the container carrying assembly 200 to move towards the direction away from the opening, the plurality of containers 222 and the container carrying assembly 200 move out of the accommodating cavity. When the first driving rod 330 drives the container carrying assembly 200 to move towards the direction of the opening, the plurality of containers 222 and the container carrying assembly 200 move into the accommodating cavity.

[0061] In some embodiments, in order to ensure that the container carrying assembly 200 can be connected to slide with the first guide assembly, the frame body 100 is further provided with a first limiting assembly. The first limiting assembly is used for limiting the movement of the container carrying assembly 200, so that the container carrying assembly 200 is limited to a predetermined position inside or outside the accommodating cavity.

[0062] In an implementation manner, the first limiting assembly can include a first photoelectric switch 111 and a limiting screw. The first photoelectric switch 111 is arranged close to the inner end of the transverse guide rail 310. The photoelectric switch can sense the position of the transverse moving plate 210 moving into the accommodating cavity, so that the transverse moving plate 210 stops after moving to a specific position inside the accommodating cavity. The limiting screw is arranged close to the outer end of the transverse guide rail 310. When the container carrying assembly 200 moves out of the accommodating cavity, the limiting screw can block the container carrying assembly 200, so that the container carrying assembly 200 stops at a set position outside the accommodating cavity.

[0063] In some embodiments, the container carrying assembly 200 includes a transverse moving plate 210 and a container limiting plate 220 arranged above the transverse moving plate 210. The transverse moving plate 210 is connected with the first guide assembly and is slidably connected with the first guide assembly. For example, a sliding block can be mounted on the transverse guide rail 310, and the transverse moving plate 210 is fixed on the sliding block and can slide along the two transverse guide rails 310 with the sliding block. Figure 3 The container limiting plate 220 and the transverse moving plate 210 are arranged in the vertical direction and are spaced apart, that is, the container limiting plate 220 and the transverse moving plate 210 have a set distance in the longitudinal direction Z, are parallel to each other and are fixedly connected through a plurality of vertical columns. The container placing part 221 includes a plurality of limiting holes 221 arranged on the container limiting plate 220. The container 222 can be placed and limited in the limiting hole 221, and the bottom of the container 222 can be supported on the upper surface of the transverse moving plate 210.

[0064] The limiting hole 221 can be a through hole penetrating through the upper and lower sides of the container limiting plate 220. The limiting hole 221 can be in a shape matching the cross-sectional shape of the container 222, for example, when the cross-sectional shape of the container 222 is circular, the limiting hole 221 can also be circular.

[0065] After the container 222 is placed in the limiting hole 221, the bottom of the container 222 can be supported on the upper surface of the transverse moving plate 210, and the side wall of the container 222 can abut against the hole wall of the limiting hole 221, thereby limiting the container 222.

[0066] In some embodiments, the first driving rod 330 can be a telescopic rod, which can be telescopic in the movement direction of the container carrying assembly 200. The transverse moving plate 210 can be fixedly connected with the telescopic rod. When the first motor 320 works, the first motor 320 can drive the telescopic rod to telescope, thereby driving the transverse moving plate 210 to move.

[0067] In some embodiments, the first driving rod 330 can be a screw rod, and a nut is sleeved on the screw rod. The nut is connected with the transverse moving plate 210. When the first motor 320 works, the first motor 320 can drive the screw rod to rotate, thereby driving the nut to slide along the screw rod, so as to drive the transverse moving plate 210 to move.

[0068] It can be understood that the first driving rod 330 can not be limited to being driven by the first motor 320. In other embodiments, the first driving rod 330 can also be driven by a pneumatic cylinder.

[0069] Referring to Figure 1 and Figure 4 In some embodiments, in order to simultaneously open or seal a plurality of containers 222, a container sealing assembly 500 is further arranged in the accommodating cavity. The container sealing assembly 500 is connected with the frame 100 through a second movement mechanism 400. The container sealing assembly 500 is arranged above the container carrying assembly 200. The container sealing assembly 500 comprises a sealing mechanism 530 corresponding to the container placing part 221 in the longitudinal direction Z. The second movement mechanism 400 is used to drive the sealing mechanism 530 to approach or move away from the container placing part 221, so as to make the sealing mechanism 530 sealingly cooperate with or be separated from the container port 2221 of the container 222.

[0070] When the pipetting operation is needed, the container sealing assembly 500 is first driven to rise by the second movement mechanism 400, so that the sealing mechanism 530 is separated from the container port 2221 of the container 222, and then the container carrying assembly 200 is driven to move out of the containing cavity by the first movement mechanism 300, so that the pipette extends into the container port 2221 to perform the pipetting. After the pipetting is completed, the container carrying assembly 200 is driven to move into the containing cavity by the first movement mechanism 300, and then the container sealing assembly 500 is driven to descend by the second movement mechanism 400, so that the sealing mechanism 530 is attached to the container port 2221 of the container 222. At this time, the plurality of containers 222 are again in a sealed state.

[0071] The solvent storage device provided by the embodiments of the present application can reduce the operation time of the pipetting process, because the plurality of containers 222 do not need to be opened and sealed one by one during the biochemical experiment, for example, the plurality of containers do not need to be taken out one by one, opened, pipetted, closed, and put back in, and the like.

[0072] Referring to Figure 4 In some embodiments, the second movement mechanism 400 includes a second guide assembly and a second driving assembly, and the container sealing assembly 500 is slidably connected to the second guide assembly. The second driving assembly is in transmission connection with the container sealing assembly 500 and is used to drive the container sealing assembly 500 to move. The second guide assembly can include two parallel longitudinal guide rails 410, and the two longitudinal guide rails 410 are arranged along the longitudinal direction Z and can be arranged on the inner side of the back plate 130 of the rack body 100. A sliding block can be mounted on the longitudinal guide rail 410, and the container sealing assembly 500 is fixed to the sliding block and can slide along the two longitudinal guide rails 410 with the sliding block.

[0073] In some embodiments, the second driving assembly includes a second motor 420 and a second driving rod 430 in transmission cooperation with the second motor 420. The second motor 420 is fixed to the rack body 100, and the second driving rod 430 is arranged along the longitudinal direction Z and located above the longitudinal moving plate 510 and fixedly connected to the upper side of the longitudinal moving plate 510.

[0074] In some embodiments, the second driving rod 430 can be a telescopic rod, the telescopic rod can be telescoped in the movement direction of the container sealing assembly 500, and the longitudinal moving plate 510 can be fixedly connected with the telescopic rod. When the second motor 420 works, the second motor 420 can drive the telescopic rod to telescope, thereby driving the longitudinal moving plate 510 to move.

[0075] In some embodiments, the second driving rod 430 can be a screw rod, a nut is sleeved on the screw rod, and the nut is connected with the longitudinal moving plate 510. When the second motor 420 works, the second motor 420 can drive the screw rod to rotate, thereby driving the nut to slide along the screw rod, so as to drive the longitudinal moving plate 510 to move.

[0076] It can be understood that the second driving rod 430 can not be limited to being driven by the second motor 420, and in other embodiments, the second driving rod 430 can also be driven by a pneumatic cylinder.

[0077] The second motor 420 of the embodiment can be a linear stepper motor, and the second motor 420 can drive the second driving rod 430 to move linearly along the axial direction thereof. The second motor 420 is fixedly arranged relative to the frame body 100, for example, the second motor 420 can be fixed to the frame body 100 by a fixing member.

[0078] In some embodiments, the solvent storage device further comprises a second limiting assembly arranged on the frame body 100, and the second limiting assembly is used for limiting the movement of the container sealing assembly 500, so that the container sealing assembly 500 is limited to a predetermined position in the longitudinal movement. The second limiting assembly can comprise a second photoelectric switch 131 and a limiting screw, the second photoelectric switch 131 is installed at a position close to the upper end of the longitudinal guide rail 410, and can limit the upward movement of the longitudinal moving plate 510; when the container sealing assembly 500 moves downward, the limiting screw can stop the container sealing assembly 500 at a set position, so that the descending height of the sealing mechanism 530 matches the height of the container, and then can be sealed with the container port 2221.

[0079] Referring to Figure 4 In some embodiments, the container sealing assembly 500 comprises a longitudinal moving plate 510 and a mounting plate 520 arranged on the longitudinal moving plate 510; the longitudinal moving plate 510 is slidably limited to the second guide assembly, and the second driving assembly is in transmission connection with the longitudinal moving plate 510; wherein a plurality of sealing mechanisms 530 are fixed to the mounting plate 520 and can move along the longitudinal direction Z with the mounting plate 520.

[0080] Referring to Figure 2 and Figure 5 In some embodiments, the arrangement form of the plurality of sealing mechanisms 530 on the mounting plate 520 is matched with the arrangement form of the plurality of container placing portions 221 on the container carrying assembly 200, so that the plurality of sealing mechanisms 530 and the plurality of container placing portions 221 correspond one by one.
