[0022] The technical scheme of the present application will be further specifically described below by means of specific embodiments and in conjunction with the drawings:

[0023] Embodiment 1

[0024] As Figure 1As shown, an automatic arrangement butt joint installation device for pipette tip, comprising a shell 1, the upper surface of the shell 1 is a sieve plate 2, the sieve plate 2 is densely covered with sieve holes 21 for the vertical passing of the tip, the shell 1 is provided with an arrangement device 3 inside, the arrangement device 3 comprises a rotating plate 31, the rotating plate 31 is rotatably installed at the lower end inside the shell 1, the upper surface of the rotating plate 31 is provided with a plurality of placing grooves 32 in the circumferential direction, the placing groove 32 is a horizontally placed semicircular conical structure, the thick end of the placing groove 32 is communicated with the outer circumferential surface of the rotating plate 1, the rotating plate 31 is further provided with a blocking structure above, the sidewall surface of the shell 1 is further provided with a butt joint hole 11, the height of the butt joint hole 11 is the same as the height of the placing groove 32. The shell 1 is a hollow structure, and a space for accommodating and arranging the pipette tip is formed inside. When personnel need to select a pipette tip, they only need to open the whole package of pipette tips and pour them on the upper surface of the shell 1. In this process, personnel do not need to arrange the shell 1. The upper surface of the shell 1 is provided with a sieve plate 2, the sieve plate 2 is densely covered with sieve holes 21, and the pipette tip can enter the inside of the shell 1 through the sieve holes 21 under the action of gravity. At the same time, the sieve holes 21 have the function of preliminarily adjusting the orientation of the pipette tip. Because the area of the sieve holes 21 is small, only when the pipette tip is in a vertical state, the pipette tip can smoothly pass through the sieve holes 21, and the pipette tip in a horizontal state cannot pass through the sieve holes 21 and is left above the sieve plate 2, or is deflected under the action of its own gravity and changes from a horizontal state to a vertical falling state. The sieve holes 21 have a flow limiting effect on a large number of pipette tips, and can only allow a certain number of pipette tips to pass through, avoiding the arrangement capacity of the device being exceeded due to too many pipette tips. At the same time, the sieve holes 21 also have the effect of preventing other large-volume foreign matters from entering the inside of the shell 1. The inside of the shell 1 is provided with an arrangement device 3, the pipette tip entering the shell 1 will fall into the arrangement device 3, and the arrangement device 3 can neatly stack the entering pipette tips. The arrangement device 3 comprises a rotating plate 31, the rotating plate 31 is rotatably installed at the bottom of the shell 1, the upper surface of the rotating plate 31 is provided with a placing groove 32, the placing groove 32 is a horizontally placed semicircular conical structure, and is similar in shape to the pipette tip. Only the pipette tip with a position and orientation matched with the placing groove 32 can completely enter the placing groove 32. The arrangement device 3 further comprises a blocking structure arranged above the rotating disc. The rotating disc continuously rotates, and the pipette tip that cannot completely enter the placing groove 32 will protrude from the upper surface of the rotating disc, and the part of the pipette tip protruding from the upper surface of the rotating disc will be blocked by the blocking structure and cannot rotate with the rotating disc, and will finally be pushed out of the placing groove 32 by the blocking structure.The blocking structure also exerts force on the pipette tip during the process, so that the position and orientation of the pipette tip changes, and when it matches the placement slot 32, the pipette tip can smoothly fall into the placement slot 32. The pipette tip in the placement slot 32 will not be blocked by the blocking structure and will rotate with the rotating disc. The placement slot 32 is provided with multiple, which can simultaneously arrange multiple pipette tips. The rough end of the placement slot 32 is connected with the outer circumferential surface of the rotating plate 31, so that the pipette tip is not blocked by any structure when moving away from the axis of the rotating plate 31, and can be directly taken out from the outer circumferential surface of the rotating plate 31. The side wall of the shell 1 is also provided with a docking hole 11, which has the same height as the placement slot 32. The rotating plate 31 can align different placement slots 32 with the docking hole 11 through continuous rotation. When a person needs to use the pipette tip, he only needs to insert the pipette into the docking hole 11, so that the pipette and the pipette tip are connected. Then pull out the pipette from the docking hole 11, and the pipette tip is also taken out of the placement slot 32, realizing the installation of the pipette tip. After the rotating disc is installed, continue to rotate to align the new placement slot 32 with the pipette tip with the docking hole 11, and the empty placement slot 32 can continue to be used to place other pipette tips.

[0025] As shown in Figure 3 The blocking structure is a fixed plate 33, which transversely closes the inside of the shell 1. The fixed plate 33 is provided with a blocking hole 34 for the tip to pass transversely. The blocking hole 34 is provided with multiple, which are arranged along the circumferential direction of the fixed plate 33. The fixed plate 33 transversely closes the inside of the shell 1, so that the pipette tip entering the inside of the shell 1 falls on the fixed plate 33. The fixed plate 33 is fixedly connected with the shell 1 and will not rotate with the rotating plate 31. The fixed plate 33 is provided with a blocking hole 34, which can pass through the pipette tip and fall into the rotating disc 31, which drives the pipette tip to rotate. When the position and orientation of the pipette tip do not match the rotating placement slot 32, the pipette tip will protrude from the upper surface of the rotating disc 31 because it cannot completely fall into the placement slot 32. During the rotation of the rotating disc 31, the pipette tip and the hole wall of the blocking hole 34 are in contact, so that the pipette tip is blocked from continuing to rotate with the rotating disc 31. At the same time, the upper surface of the rotating disc 31 has friction on the pipette tip, and the hole wall of the blocking hole 34 also has a powerful effect on the pipette tip. Under the action of multiple forces, the position and orientation of the pipette tip will change constantly, and finally the position of the pipette tip will match the placement slot 32 and completely fall into the placement slot 32.

[0026] As shown in Figure 3As shown, the number of blocking holes 34 is one less than the number of placement grooves 32, and the position of the one less blocking hole 34 is aligned with the position of the docking hole 11. When the placement groove 32 is rotated to the position of the docking hole 11, the function of the placement groove 32 at this time is to dock and install the pipette tip. When the pipette is inserted into the docking hole 11 to dock the pipette tip, a pushing force will be generated on the pipette tip located in the placement groove 32. If a blocking hole 34 is still provided above the placement groove 32 at this time, the pipette tip will be pushed out of position by the pipette, and docking cannot be performed. Therefore, the number of blocking holes 34 is one less than the number of placement grooves 32, and the position of the one less blocking hole 34 is aligned with the position of the docking hole 11. This position will block the pipette tip in the placement groove 32 and prevent it from being pushed out of position.

The placement groove 32 is provided at the edge of the rotating plate 31, and there is a part of idle space at the center of the rotating plate 31, and it will be difficult for the pipette tip to slide into the placement groove 32 after falling into the idle space. Therefore, the rotating plate 31 is centrally provided with a conical protruding portion 35, which occupies the original idle space, and when the pipette tip falls into this place, it will slide along the conical surface of the protruding portion 35 to the place where the placement groove 32 is provided at the edge of the rotating plate 31. The fixed plate 33 is centrally provided with a rotating hole 36, and the protruding portion 35 is inserted into the rotating hole 36 and rotatably connected to the hole wall surface of the rotating hole 36, so that the protruding portion 35 can protrude from the upper surface of the fixed plate 33 without affecting the fixed plate 33 to remain stationary. The protruding portion 35 rotates with the rotating plate 31, so that the protruding portion 35 has a stirring effect on the pipette tip located above the fixed plate 33, making it easier for the pipette tip to fall into the placement groove 32 through the blocking hole 34.

[0028] As shown in Figure 3 , the rotating plate 31 is centrally provided with a protruding portion 35, which is a conical structure with a pointed top, and the fixed plate 33 is centrally provided with a rotating hole 36, and the protruding portion 35 is inserted into the rotating hole 36 and rotatably connected to the hole wall surface of the rotating hole 36. The placement groove 32 is provided at the edge of the rotating plate 31, and there is a part of idle space at the center of the rotating plate 31, and it will be difficult for the pipette tip to slide into the placement groove 32 after falling into the idle space. Therefore, the rotating plate 31 is centrally provided with a conical protruding portion 35, which occupies the original idle space, and when the pipette tip falls into this place, it will slide along the conical surface of the protruding portion 35 to the place where the placement groove 32 is provided at the edge of the rotating plate 31. The fixed plate 33 is centrally provided with a rotating hole 36, and the protruding portion 35 is inserted into the rotating hole 36 and rotatably connected to the hole wall surface of the rotating hole 36, so that the protruding portion 35 can protrude from the upper surface of the fixed plate 33 without affecting the fixed plate 33 to remain stationary. The protruding portion 35 rotates with the rotating plate 31, so that the protruding portion 35 has a stirring effect on the pipette tip located above the fixed plate 33, making it easier for the pipette tip to fall into the placement groove 32 through the blocking hole 34.
