Description

Technical Field

[0001] The utility model relates to the technical field of pipette tip filling, in particular to a handheld micropipette tip filling device. Background Art

[0002] When conducting scientific experiments in universities and research institutes, micropipettes are often used to transfer samples. In this process, many micropipette tips of corresponding sizes are used. In order to ensure the accuracy of experimental data and avoid reagent contamination, disposable tips are usually used in huge quantities. Due to funding reasons, many laboratories cannot purchase pre-installed tips and can only purchase bulk tips, which are then manually loaded into pipette tip boxes. Since the size of micropipette tips is relatively small, it is difficult to smoothly insert them into the tip box holes during the filling process, and they are easy to fall off. If the number of loadings is large, it often takes a long time.

[0003] Therefore, a simple filling device is needed that can quickly solve the filling problem and appropriately save research funds. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a handheld micropipette gun tip filling device, which can simply and efficiently arrange a plurality of gun tips in an orderly manner, and then can accurately and quickly transfer the arranged gun tips to a gun tip box.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] A handheld micropipette tip filling device, comprising:

[0007] A comb-shaped main board is provided with a plurality of main board arrangement grooves arranged side by side, the main board arrangement grooves are used to hold gun tips, the lower part of the gun tips in the main board arrangement grooves protrudes from the lower end surface of the main board, and the main board is tilted so that the plurality of gun tips in the main board arrangement grooves abut against each other;

[0008] A sub-plate, comprising a comb-shaped sub-plate body and a dispersion portion arranged at one end of the sub-plate body, wherein the sub-plate body is provided with a plurality of sub-plate arrangement grooves arranged in parallel, and the dispersion portion is provided with a plurality of dispersion grooves in a discrete shape, and the dispersion grooves are connected with the sub-plate arrangement grooves;

[0009] Move the sub-plate from below the main plate in a direction perpendicular to the main plate arrangement groove, so that the lower part of the gun head in the main plate arrangement groove slides into the sub-plate arrangement groove along the dispersion groove, thereby making the gun heads in the main plate arrangement groove spaced apart and the lower end of the gun head protrude from the lower end surface of the sub-plate.

[0010] As a preferred embodiment, the shape and size of the cross-section of the mainboard arrangement groove are adapted to the shape and size of the upper portion of the gun head, so that the upper portion of the gun head is vertically stuck in the mainboard arrangement groove, and the lower end of the gun head protrudes from the lower end surface of the mainboard.

[0011] As a preferred embodiment, a cover plate slide groove is provided on the main board, the length direction of the cover plate slide groove is consistent with the length direction of the main board arrangement groove, a cover plate is slidably arranged in the cover plate slide groove, a buckle is arranged on the upper end surface of the cover plate, and the cover plate slides into place to prevent the gun head from rising.

[0012] As a preferred implementation, the cover plate is made of a transparent material.

[0013] As a preferred embodiment, the end of the dispersion portion is pointed and provided with an inclined surface, so that the end of the dispersion groove corresponds to the lower end of the gun head.

[0014] As a preferred embodiment, two ridges are symmetrically arranged on both sides of the upper end surface of the sub-board body, and two mainboard slots are opened on the lower end surface of the main board corresponding to the two ridges. The ridges are slidably arranged in the mainboard slots to guide the sub-board to move into place.

[0015] As a preferred embodiment, a mainboard handle is provided on a side of the mainboard away from the mainboard arrangement groove, and a sub-board handle is provided on a side of the sub-board away from the dispersion portion.

[0016] The beneficial effects of adopting the above technical solution are:

[0017] The present application firstly quickly places a plurality of gun heads into the mainboard arrangement groove of the mainboard, with the same number of gun heads in each mainboard arrangement groove, and then tilts and shakes the mainboard so that the plurality of gun heads in the mainboard arrangement groove are neatly abutted in a row. At this time, since the gun heads are tapered as a whole, the middle parts of two adjacent gun heads abut against each other, and there is a gap between the lower parts of the two adjacent gun heads; then, the sub-board is moved to fit the lower end surface of the mainboard, and the moving direction is perpendicular to the length direction of the mainboard arrangement groove. During the moving process, the dispersion groove at the front end of the sub-board and the gap between the lower parts of the two adjacent gun heads are used to In the gap, separate the two gun heads that are pressed against each other, and guide the gun heads to the arrangement slots of the sub-plate during the movement. When the sub-plate is moved into place, use the staggered arrangement slots of the sub-plate and the arrangement slots of the main plate to fix several gun heads in a grid array. At this time, the gun heads correspond to the gun head holes of the gun head accommodating disk on the gun head box one by one. Hold the main plate and the sub-plate and lower them to the bottom of the gun head and enter the gun head hole. Pull out the sub-plate, continue to lower the main plate so that the gun head is stably fixed in the gun head hole, and then pull out the main plate to complete the process of filling several gun heads into the gun head box. The above operation process achieves the purpose of rapid arrangement and accurate stacking of gun heads in a scattered state. Compared with the operation of manually inserting the gun heads into the gun head box one by one, the device of the present application is more efficient and quick, and reduces the number of direct contacts with the gun heads. The gun heads are not easy to be contaminated. At the same time, the overall volume of the main plate and the sub-plate is small, which is convenient for storage and placement in the laboratory, and is flexible and light when operated manually.

[0030] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is clearly and completely described below in conjunction with specific embodiments.

[0031] like Figures 1 to 8 The handheld micropipette tip loading device shown comprises:

[0032] A comb-shaped main board 1 is provided with a plurality of main board arrangement slots 1-1 arranged side by side. The main board arrangement slots 1-1 are used to hold gun tips 200. The lower part of the gun tips 200 in the main board arrangement slots 1-1 protrudes from the lower end surface of the main board 1. The main board 1 is tilted so that the plurality of gun tips 200 in the main board arrangement slots 1-1 abut against each other.

[0033] A sub-plate 2, comprising a comb-shaped sub-plate body 2-1 and a dispersion portion 2-2 arranged at one end of the sub-plate body 2-1, wherein the sub-plate body 2-1 is provided with a plurality of sub-plate arrangement grooves 2-1-1 in parallel, and the dispersion portion 2-2 is provided with a plurality of dispersion grooves 2-2-1 in a discrete manner, and the dispersion grooves 2-2-1 are connected with the sub-plate arrangement grooves 2-1-1;

[0034] Move the sub-plate 2 from the bottom of the main plate 1 along a direction perpendicular to the main plate arrangement groove 1-1, so that the lower part of the gun head 200 in the main plate arrangement groove 1-1 slides into the sub-plate arrangement groove 2-1-1 along the dispersion groove 2-2-1, thereby making the gun heads 200 in the main plate arrangement groove 1-1 spaced apart and the lower end of the gun head 200 protrudes from the lower end surface of the sub-plate 2.

[0035] In this embodiment, a mainboard handle 1-2 is provided on a side of the mainboard 1 away from the mainboard arrangement slot 1-1, and a sub-board handle 2-3 is provided on a side of the sub-board 2 away from the dispersion portion 2-2.

[0036] See also Figure 3The shape and size of the cross section of the mainboard arrangement groove 1-1 match the shape and size of the upper part of the gun head 200. Specifically, the gun head 200 is approximately conical, and the cross section of the mainboard arrangement groove 1-1 is also approximately conical, so that the upper part of the gun head 200 is vertically stuck in the mainboard arrangement groove 1-1, and the lower end of the gun head 200 protrudes from the lower end surface of the mainboard 1. In the embodiment, both sides of the upper end of the mainboard arrangement groove 1-1 are provided with trumpet-shaped chamfers with the opening facing upward, which is convenient for receiving the gun head 200. The mainboard chamfered parts 1-4 are also provided around the area on the upper end surface of the mainboard 1 corresponding to the mainboard arrangement groove 1-1, so as to prevent the gun head 200 from being scattered outside the mainboard 1 when the gun head 200 is quickly placed.

[0037] See also Figure 3 and Figure 4 The main board 1 is provided with a cover plate slide 1-5, the length direction of the cover plate slide 1-5 is consistent with the length direction of the main board arrangement slot 1-1, and a cover plate 3 is slidably arranged in the cover plate slide 1-5, and a buckle 3-1 is arranged on the upper end surface of the cover plate 3, and the cover plate 3 slides into place to prevent the gun head 200 from rising. The setting of the cover plate 3 can prevent the gun head 200 from rising and escaping from the guidance of the dispersion slot 2-2-1 during the movement of the sub-board 2. The cover plate 3 is made of a transparent material, such as a transparent acrylic plate material, which is convenient for observing the arrangement process.

[0038] See also Figure 7 , looking from top to bottom, the dispersion part 2-2 of this embodiment is in the shape of a right-angled trapezoid, so that the end of the dispersion part 2-2 is pointed, one right-angle side of which is flush with the side of the comb-shaped sub-board body 2-1, and the other side of which is connected to the other side of the sub-board body 2-1. The dispersion grooves 2-2-1 on the dispersion part 2-2 are discrete, so that the sub-board 2 can guide the gun head 200 to move to the sub-board arrangement groove 2-1-1 during the movement process. At this time, the gun head 200 slides in the main board arrangement groove 1-1, so that the two gun heads 200 that originally abutted against each other in the main board arrangement groove 1-1 are arranged at intervals. See Figure 8 The front end of the dispersion part 2-2 is provided with an inclined surface, so that the front end entrance of the dispersion groove 2-2-1 is directly opposite to the lower part of the gun head 200. The gap between two adjacent gun heads 200 becomes larger as it is closer to the lower end. Therefore, the design of the inclined surface is conducive to the lower end of the gun head 200 entering the dispersion groove 2-2-1.

[0039] See also Figure 3 , Figure 4 and Figure 8Two convex ridges 2-4 are symmetrically arranged on both sides of the upper end surface of the sub-board body 2-1, and two mainboard slots 1-3 are opened on the lower end surface of the mainboard 1 corresponding to the two convex ridges 2-4. The convex ridges 2-4 are slidably arranged in the mainboard slots 1-3 to guide the sub-board 2 to move into position. In this embodiment, when the mainboard 1 is tilted and shaken, the gun head 200 slides along the mainboard arrangement slot 1-1 to one side of the mainboard 1 (i.e., the side away from the outlet of the mainboard arrangement slot 1-1), and is located between the opening positions of the two mainboard slots 1-3.
