[0034] Combination Figures 1 to 5 As shown, the carrier device provided in this embodiment can limit the relative position of the gun tip box 10 and the carrier body 100. Specifically, the carrier device includes a carrier body 100 and an adjustment limit member 200. The upper surface of the carrier body 100 has a first opening 110 for placing the gun tip box 10; the adjustment limit member 200 is connected to the carrier body 100 and is located on one side of the first opening 110. The adjustment limit member 200 cooperates with the first opening 110 to limit the relative position of the gun tip box 10.

[0035] Since an adjustment limit piece 200 is provided on one side of the first opening 110, when the gun tip box 10 is placed in the first opening 110, the adjustment limit piece 200 abuts against the gun tip box 10, which can limit the relative position of the gun tip box 10 and the first opening 110, thereby preventing the gun tip box 10 from moving with the pipette or the gun tip box 10 from detaching from the first opening 110 during the process of replacing the gun tip and removing the pipette from the gun tip box 10, thereby improving the convenience of replacing the gun tip.

[0036] When limiting the position of the gun tip box 10 placed in the first opening 110, an adjustment limit piece 200 can be set only on one side of the first opening 110, so that the gun tip box 10 and the adjustment limit piece 200 have an interference fit; or an elastic snap-fit ​​assembly 300 can be set on the adjustment limit piece 200, so that the adjustment limit piece 200 and the elastic snap-fit ​​assembly 300 cooperate to achieve the elastic snap-fit ​​assembly 300 and the abutment with the gun tip box 10, thereby limiting the relative position of the gun tip box 10. At the same time, it is convenient for the disassembly and maintenance of the gun tip box 10 after the pipetting is completed.

[0037] Preferably, a plurality of adjustment limit members 200 are provided, and the side walls of the gun head box 10 corresponding to the plurality of adjustment limit members 200 can be detachably connected to the carrier body 100. The number of adjustment limit members 200 corresponding to the side walls of the gun head box 10 can be set to two, three or four, and the specific number of settings can be appropriately increased or decreased according to actual needs. In this embodiment, two adjustment limit members 200 are provided, and the two adjustment limit members 200 correspond to the two opposite side walls on the gun head box 10, which can be detachably connected to the carrier body 100 and are both located on one side of the first opening 110, and the two adjustment limit members 200 are both provided with elastic snap-on components 300, such as Figure 1 and Figure 2Such a configuration can better limit the relative position of the gun tip box 10 in the first opening 110 from two directions, further improving the convenience of replacing the gun tip.

[0038] In some other embodiments, the elastic clamping assembly 300 may be disposed on only one of the adjustment and limiting members 200 , and the other adjustment and limiting members 200 directly abut against the side wall of the gun tip box 10 .

[0039] Preferably, the elastic snap-fit ​​assembly 300 includes an elastic member 310 and an abutment member 320 , the first end of the elastic member 310 is fixedly connected to the adjustment limit member 200 , and the second end extends toward the middle of the first opening 110 , the abutment member 320 is connected to the second end of the elastic member 310 , and abuts against the gun tip box 10 .

[0040] Specific combination Figures 3 to 5 As shown, a clamping limit portion is provided at the bottom of the gun tip box 10, and the elastic member 310 is configured as a compression spring. Before the gun tip box 10 is placed in the first opening 110, the compression spring is compressed under external force, and the abutment member 320 moves in a direction away from the first opening 110 along with the compression spring, so as to facilitate the gun tip box 10 to be placed in the first opening 110; after the gun tip box 10 is placed in the first opening 110, the external force on the compression spring is released, the compression spring extends back, and brings the abutment member 320 to abut against the clamping limit portion, limiting the relative position of the gun tip box 10, and preventing the pipette from taking the gun tip and driving the gun tip box 10 to move; when the gun tip box 10 needs to be removed, the gun tip box 10 is pushed as a whole in the direction of one of the adjustment limit members 200, so that the compression spring corresponding to the adjustment limit member 200 is compressed, so that a gap appears between the gun tip box 10 and the other adjustment limit member 200, thereby facilitating the disassembly of the gun tip box 10.

[0041] In order to further improve the convenience of placing the gun tip box 10 in the first opening 110, or removing the gun tip box 10 from the first opening 110, the abutment 320 can be set to a columnar shape, and the end surface of the abutment 320 facing away from the elastic member 310 can be set as a guide surface, or the abutment 320 can be directly set to a sphere, thereby further improving the convenience of replacing the gun tip.

[0042] Preferably, the elastic clamping assembly 300 further includes a guide groove 330, which is arranged on the first side wall 210 of the adjustment limiter 200, and the first end of the elastic member 310 is fixedly connected to the bottom wall of the guide groove 330. The length of the compression spring is greater than or equal to the depth of the guide groove 330; during the disassembly and assembly of the gun tip box 10, the compression spring is compressed, and the abutment member 320 is compressed into the guide groove 330 to facilitate the disassembly and assembly of the gun tip box 10; after the gun tip box 10 is placed in the first opening 110, the compression spring retracts automatically, and the abutment member 320 extends to the open end of the guide groove 330 and abuts against the corresponding side wall of the gun tip box 10 to limit the relative position of the gun tip box 10. During the compression or self-retraction of the compression spring, the guide groove 330 guides and limits the compression spring, guides the compression spring to move along a predetermined path, and avoids bending and tilting during the movement of the compression spring, thereby further ensuring the limiting effect of the gun tip box 10.

[0043] In some other embodiments, the elastic clamping assembly 300 further includes an auxiliary member 340, an auxiliary channel is provided on the guide groove 330, the auxiliary member 340 is connected to the elastic member 310 or the abutting member 320, and extends out of the adjustment limit member 200 through the auxiliary channel. Specifically, at least one of the abutting members 320 is connected to the auxiliary member 340, and the auxiliary channel is provided on the guide groove 330 corresponding to the abutting member 320; when the gun tip box 10 needs to be removed, the auxiliary member 340 is pulled to move away from the gun tip box 10, so that the elastic member 310 is compressed, so that a gap appears between the gun tip box 10 and the other adjustment limit member 200, thereby facilitating the removal of the gun tip box 10.

[0044] In order to further improve the limiting effect of the gun tip box 10, a plurality of elastic clamping components 300 are arranged at intervals on the adjusting and limiting member 200. In this embodiment, two elastic clamping components 300 are arranged at intervals on one adjusting and limiting member 200.

[0045] Preferably, a plurality of second openings 120 for accommodating the carrier 20 are disposed at intervals on the carrier body 100 .

[0046] Combination Figure 1 and Figure 2 As shown, the number of carriers 20 is appropriately increased or decreased according to actual needs, and the number of second openings 120 corresponds to the number of carriers 20, which can achieve the technical effect of storing source liquid or contaminated liquid, and improving the overall convenience of the pipetting workstation. In this embodiment, three second openings 120 are arranged at intervals on the carrier body 100, and three corresponding carriers 20 are also arranged.

[0047] The liquid transfer workstation includes a frame, a liquid transfer device and a carrier device. The carrier device and the liquid transfer device are both arranged on the frame. The liquid transfer device cooperates with the carrier device to realize the replacement of the gun tip or liquid transfer. The carrier device and the liquid transfer device are arranged at intervals on the upper end surface of the frame. The liquid transfer device is used to install the pipette. The liquid transfer device can change the relative position of the pipette and the frame. The pipette is used for liquid transfer. According to actual needs, the gun tip in the gun tip box 10 is installed on the pipette, and then the liquid transfer device moves the source liquid in the carrier 20 to the target container to carry out the next production step.
