[0027] The present application provides a pipette tip assembly device that can be used to install a pipette tip into a pipette tip box 100, see Figure 7 As shown, the pipette tip box 100 is provided with multiple rows of placement holes 101, and each row of placement holes 101 is provided with multiple placement holes 102. The pipette tip assembly device provided in the present application can install the pipette tip into the placement hole 102 of the pipette tip box.

[0028] See also Figure 1-Figure 6 As shown, the pipette tip assembly device provided in this embodiment is mainly used to load the pipette tips into the pipette tip box 100, wherein the pipette tip assembly device includes: a sorting mechanism 10, a spacing adjustment mechanism 20 and an oscillation mechanism 30. The pipette tips are placed in the sorting mechanism 10, and the oscillation mechanism 30 is used to oscillate the pipette tips so that the pipette tips can be sorted in the sorting mechanism 10 along directions parallel to each other, and the spacing adjustment mechanism 20 can adjust the spacing between two adjacent pipette tips in the same column of pipette tips so that the spacing is equal to the spacing between two adjacent placement holes in the same row of placement holes in the pipette tip box 100.

[0029] The sorting mechanism 10 includes: a side enclosure 11, a plurality of support bars 12 and a plurality of support fixing portions 13. The plurality of support bars 12 are arranged in parallel inside the side enclosure 11, and a sorting groove 120 is formed between two adjacent support bars 12. In this embodiment, the pipette tips are placed inside the sorting mechanism 10, and the sorting mechanism 10 is oscillated so that the pipette tips can be arranged in an orderly manner in the sorting groove 120. Specifically, the pipette tips are arranged in the sorting groove 120 in an inverted manner, that is, the tail of the pipette tip is located at the top and the head of the pipette tip is located at the bottom.

[0030] In order to facilitate the insertion of the pipette tip into the sorting slot 120, Figure 4 As shown, the top width H of the sorting groove 120 is set to be larger than the tail width of the pipette tip, and the bottom width h of the sorting groove 120 is set to be smaller than the middle width of the pipette tip, so that the pipette tip can be stuck in the sorting groove 120, and the bottom of the pipette tip extends out of the sorting groove 120. A plurality of supporting fixing portions 13 are provided on the side enclosure 11, and are used to fix the side enclosure 11 on the pipette tip box 100 and maintain a preset gap 200 with the pipette tip box 100.

[0031] In this embodiment, the shape and size of the sorting mechanism 10 are substantially the same as those of the pipette tip box 100 . The pipette tip box 100 is usually rectangular in shape, and the shape and size of the side panel 11 are substantially the same as those of the pipette tip box 100 .

[0032] like Figure 5 and Figure 6 As shown, the spacing adjustment mechanism 20 includes: a body 21 and a plurality of comb teeth 22, wherein the plurality of comb teeth 22 are arranged on the body 21 in parallel with each other, and the spacing between two adjacent comb teeth 22 is the same as the spacing between two adjacent placement holes 102 in the same placement hole row 101 in the pipette tip box. Figure 2 As shown, the spacing adjustment mechanism 20 is used to be inserted from the preset gap 200 to adjust the spacing between two adjacent pipette tips in the same sorting slot 120, so that the spacing between two adjacent pipette tips in the same sorting slot 120 is equal to the spacing between two adjacent placement holes 102 in the same placement hole row 101 in the pipette tip box, thereby positioning the pipette tips in each placement hole 102.

[0033] The oscillation mechanism 30 is used to carry the pipette tip box and provide an oscillation environment.

[0034] In some embodiments, a storage tray 31 is provided on the oscillation mechanism 30 , and the pipette tip box 100 is placed in the storage tray 31 .

[0035] In the present application, the pipette tips are placed in the sorting mechanism 10, and the sorting mechanism 10 is fixedly connected to the pipette tip box 100 through the supporting fixing portion 13, so that a preset gap 200 is maintained between the side 11 and the pipette tip box 100. The pipette tip box 100 is carried on the oscillation mechanism 30, and the oscillation mechanism 30 starts to work to generate an oscillation environment, so that the pipette tips are orderly arranged in each sorting slot 120. After the pipette tips are orderly arranged in each sorting slot 120, the bottom of the pipette tip is supported on the top of the sorting slot 120, the middle of the pipette tip is supported on the bottom of the sorting slot 120, and the top of the pipette tip extends out of the sorting slot 120. The spacing adjustment mechanism 20 is inserted from the preset gap 200, and under the action of the plurality of comb teeth 22, the spacing between two adjacent pipette tips in the same sorting slot 120 is equal to the spacing between two adjacent placement holes 102 in the same placement hole row 101 in the pipette tip box, so that the pipette tips can be positioned and placed in each placement hole 102. In this way, the present device, through the oscillation environment provided by the oscillation mechanism 30, enables each pipette tip placed in the sorting mechanism 10 to be orderly arranged in the sorting slot 120, and adjusts the spacing between two adjacent pipette tips in the same sorting slot 120 to be equal to the spacing between two adjacent placement holes 102 in the same placement hole row 101 in the pipette tip box through the spacing adjustment mechanism 20, so that the pipette tips can be automatically assembled into the pipette tip box, thereby improving assembly efficiency.

[0036] After the pipette tips are positioned and assembled into the placement holes 102 of the pipette tip box 100, the sorting mechanism 10 needs to be removed. In one embodiment of the present application, an opening (not shown in the figure) is further provided at one end of the side enclosure 11 along the length direction of the support bar 12, and an openable or closable side panel 14 is provided at the opening. The sorting mechanism 10 can be separated from the pipette tips by opening the side panel 14 and pulling out the sorting mechanism 10 along the length direction of the support bar 12.

[0037] In some embodiments, the side panels 14 are hinged to the side enclosures 11 . More specifically, the side panels 14 are hinged to the openings of the side enclosures 11 via hinges.

[0038] In the process of inserting the spacing adjustment mechanism 20 from the preset gap 200, in order to prevent the comb teeth 22 from being squeezed at the same time and affecting the adjustment, in this embodiment, the lengths of the multiple comb teeth 22 are increased successively along the sorting direction of the multiple comb teeth 22, so that the longer comb teeth 22 can be inserted first, and the shorter comb teeth 22 adjacent to the longer comb teeth 22 can be inserted later.

[0039] In this embodiment, Figure 6As shown, the length L of the plurality of comb teeth 22 increasing gradually is greater than or equal to the width of the pipette tip. Specifically, if the pipette tip is a columnar structure, the width of the pipette tip is its outer diameter. More specifically, since the bottom of the pipette tip extends into the preset gap 200, the length L of the plurality of comb teeth 22 increasing gradually should be greater than or equal to the outer diameter of the bottom of the pipette tip.

[0040] In one embodiment, in order to facilitate the smooth insertion of the comb teeth 22 , a guiding inclined surface 220 is further provided at the end of the comb teeth 22 away from the main body 21 .

[0041] The spacing adjustment mechanism 20 further includes a handle 23 , which is disposed on the body 21 for the convenience of an operator to hold and operate.

[0042] In one embodiment of the present application, in order to make the top width H of the sorting groove 120 larger than the tail width of the pipette tip, and the bottom width h of the sorting groove 120 smaller than the middle width of the pipette tip, when manufacturing the support bar 12, the upper end width of the support bar 12 is smaller than the lower end width.

[0043] In one embodiment, the end surface of the bottom end of the support bar 12 and the end surface of the bottom end of the side wall 11 are in the same plane, so that the bottom of the pipette tip can be extended to the preset gap 200, which is convenient for adjusting the spacing of the pipette tips.

[0044] like Figure 4 As shown, the support bar 12 has an upper support portion 121 and a lower support portion 122, the lower support portion 122 is connected to the bottom of the upper support portion 121, the spacing between the upper support portions 121 of two adjacent support bars 12 forms the top width H of the sorting groove 120, and the spacing between the lower support portions 122 of two adjacent support bars 12 forms the bottom width h of the sorting groove 120.

[0045] In summary, the pipette tip assembly device provided by the present application places the pipette tip in the sorting mechanism, and the sorting mechanism and the pipette tip box are fixedly connected by a supporting fixed portion, so that the preset gap is maintained between the side circumference and the pipette tip box, and the pipette tip box is carried on the oscillation mechanism, and the oscillation mechanism starts to work to generate an oscillation environment, so that the pipette tips are arranged in order in each sorting slot. After the pipette tips are arranged in order in each sorting slot, the spacing adjustment mechanism is inserted from the preset gap, and under the action of multiple comb teeth, the spacing between two adjacent pipette tips in the same sorting slot is adjusted to be equal to the spacing between two adjacent placement holes in the same placement hole row in the pipette tip box. In this way, the device, through the oscillation environment provided by the oscillation mechanism, enables each pipette tip placed in the sorting mechanism to be arranged in order in the sorting slot, and the spacing between two adjacent pipette tips in the same sorting slot is adjusted by the spacing adjustment mechanism to be equal to the spacing between two adjacent placement holes in the same placement hole row in the pipette tip box, so as to improve the assembly efficiency of the pipette tip.
