Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 and Figure 2The present embodiment provides an automatic sorting and boxing device for pipette tips, including a sorting component 100, a transport component 200 and a collecting component 300. The sorting component 100 includes a hopper 101, a slotted plug plate 102, a first driving member 103, a bracket 104 and a fixing block 105. The slotted plug plate 102 is arranged at the bottom of the hopper 101, the first driving member 103 is connected to the slotted plug plate 102, the hopper 101 is arranged on the bracket 104, and the fixing block 105 is axially connected to one end of the slotted plug plate 102; the transport component 200 is arranged on one side of the hopper 101, and the transport component 200 is placed obliquely; the collecting component 300 is arranged at the end of the transport component 200. The first driving member 103 includes a driving motor 103a, a cam 103b, a connecting rod 103c, a rod sleeve 103d and a support plate 103e, wherein the driving motor 103a and the rod sleeve 103d are arranged on the support plate 103e, the connecting rod 103c is arranged in the rod sleeve 103d to connect the slotted plug plate 102 and the cam 103b, and the cam 103b is arranged below the rod sleeve 103d to connect the driving motor 103a. The hopper 101 is a trapezoidal platform housing without upper and lower bottoms, and the slotted plug plate 102 is matched with the bottom surface of the hopper 101.

[0033] In this embodiment, the sorting component 100 arranges the scattered pipette tips and transports them to the collection component 300 for boxing through the transport component 200. Specifically, the upper bottom opening of the hopper 101 is large, and the lower bottom opening is small, which has the effect of a funnel, and the scattered tips are concentrated at the bottom of the hopper. When in use, the first driving member 103 controls the slotted plug plate 102 to reciprocate up and down. During the movement, the placement position of the tips will change, and some of the tips will slide into the grooves on the slotted plug plate 102. The structure of the pipette tip is that there is a large end with a larger diameter at the upper end and a small end with a smaller diameter at the lower end. The groove on the slotted plug plate 102 is slightly larger than the small end of the tip and smaller than the large end of the tip. The effect achieved by this structure is that the tip slides into the groove of the slotted plug plate 102 under the action of gravity, and the small end of the tip falls into the groove while the large end does not, so as to achieve the purpose of placing the tip in a certain posture.

[0034] Furthermore, the first driving member 103 is controlled by the driving motor 103a to rotate the cam 103b, and the connecting rod 103c is limited by the rod sleeve 103d and can only move up and down. The connecting rod 103c is arranged above the cam 103b and contacts the cam 103b under the action of gravity. When the cam 103b rotates, the connecting rod 103c is driven to move up and down. A connecting handle is also arranged on the slotted plug board 102, and the connecting handle is axially connected with the fixed block 105, so that the slotted plug board 102 can rotate with the fixed block 105 as the rotation center. One end of the connecting rod 103c contacts the cam 103b, and the other end is connected to the middle part of the connecting handle. When the connecting rod 103c moves up and down, the slotted plug board 102 is also driven to rotate around the fixed block 105. Because the height change of the cam 103b lifting the connecting rod 103c is now within a certain range, the up and down reciprocating motion of the slotted plug board 102 is also limited within a certain range. The transport component 200 is placed at an angle to ensure that the suction head can slide down along the transport component 200 under the action of its own gravity to ensure its smooth transmission. When the slotted plug plate 102 is in motion, the slots thereon will also have changes in the inclination angle. It should be noted that the minimum inclination angle of the slots on the slotted plug plate 102 is flush with the bottom of the hopper 101 to ensure that all the suction heads in the hopper 101 can fall into the slots. The maximum inclination angle of the slots on the slotted plug plate 102 is consistent with the inclination angle of the transport component 200, and at this time the slotted plug plate 102 is docked with the transport component 200 to achieve smooth transfer of the suction head from the slotted plug plate 102 to the transport component 200.

[0035] Example 2

[0036] Reference Figure 3 The difference between this embodiment and the previous embodiment is that the transport component 200 includes a feed track 201, a push rod motor 202, a baffle 203 and a collection trough 204, the baffle 203 is arranged at the end of the feed track 201, the baffle 203 is connected to the push rod motor 202, and the collection trough 204 is arranged below the feed track 201.

[0037] In this embodiment, the feeding track 201 and the collecting slot 204 are both in an inclined state, one end of the feeding track 201 is used to dock with the slotted insert plate 102, and the collecting assembly 300 is docked with the other end of the feeding track 201. The baffle 203 is arranged between the collecting assembly 300 and the feeding track 201. The movement of the baffle 203 is controlled by the push rod motor 202, which is specifically reflected in whether the baffle 203 hinders the transportation of the suction head between the feeding track 201 and the collecting assembly 300. The collecting slot 204 is arranged to collect suction heads that slide down in a wrong posture.

[0038] Example 3

[0039] Reference Figures 4 to 8The difference between this embodiment and the previous embodiment is that the collecting assembly 300 includes a clamping blanking piece 301, a guide piece 302 and a storage piece 303, and the clamping blanking piece 301, the guide piece 302 and the storage piece 303 are placed in sequence from top to bottom. The clamping blanking piece 301 includes a pillar 301a, a placement table 301b, a fixed plate 301c, a movable plate 301d, a crank slider 301e and a first motor 301f, the placement table 301b is arranged above the pillar 301a, the movable plate 301d is connected to the slider of the crank slider 301e, the first motor 301f is connected to one end of the crank of the crank slider 301e, and the fixed plate 301c is arranged on the placement table 301b; the clamping blanking piece 301 is tilted at a certain angle, and the fixed block 105 is arranged on the placement table 301b. The fixed plate 301c and the movable plate 301d are placed opposite to each other, and the opposite surfaces of the fixed plate 301c and the movable plate 301d are provided with an inclined surface; the fixed plate 301c is connected to the placing platform 301b through the fixing frame 301g. The guide member 302 includes a connecting strip 302a, two side baffles 302b and a partition 302c, the connecting strip 302a connects one side of the two side baffles 302b and the fixed plate 301c, and the partition 302c is arranged between the two side baffles 302b. The storage member 303 includes a placing box 303a, a placing frame 303b and a guide rail seat 303c, the placing box 303a is arranged on the placing frame 303b, and the placing frame 303b is arranged on the guide rail seat 303c.

[0040] The storage piece 303 also includes a second motor 303d and a screw rod 303e. The second motor 303d is arranged on one side of the guide rail seat 303c, and the second motor 303d is connected to the screw rod 303e. A threaded hole 303b-1 is arranged on the placement rack 303b, and the screw rod 303e is connected to the threaded hole 303b-1. A positioning angle 303b-2 is arranged above the placement rack 303b.

[0041] In this embodiment, the suction heads are transported to the clamping blanking piece 301 by the transport component 200, and the clamping blanking piece 301 arranges them and blanks them when a certain number is reached, so that the suction heads fall into the guide piece 302, and the suction heads are transported to the placement holes on the placement box 303a via the guide piece 302.

[0042] Specifically, the placement box 303a for placing pipette tips is usually 8*12 in size, that is, there are 12 placement holes in each row, and there are 8 rows. Taking the placement box of this size as an example, the placement box 303a is set on the placement rack 303b, and the positioning angle 303b-2 allows the placement box 303a to be placed in a uniform placement position, and this position makes one row of 12 placement holes of the placement box 303a just correspond to the compartments in the guide 302. It should be noted that in the guide 302, the partition 302c divides the baffles 302b on both sides into 12 compartments, so the tips can enter the compartments in the guide 302 and can accurately fall into the placement holes on the placement box 303a. The fixed plate 301c and the movable plate 301d are placed opposite to each other, and a gap is formed in the middle to clamp the suction head. The suction head slides off the feeding track 201 and enters the fixed plate 301c and the movable plate 301d to be clamped by them. The distance between them can be adjusted as the position of the movable plate 301d changes. Its length can accommodate 12 suction heads. The connecting strip 302a connects the baffles 302b on both sides to the bottom of the fixed plate 301c, so that the 12 compartments on the baffles 302b on both sides correspond to the positions of the 12 suction heads above. When 12 suction heads are fully placed, the push rod motor 202 immediately moves to block the baffle 203 at the end of the feeding track 201 to prevent the suction head from sliding down further. At the same time, the first motor 301f moves, driving the crank slider 301e to move the movable plate 301d away, so that the suction head slides down, and the 12 suction heads fall one by one into the 12 compartments in the baffles 302b on both sides, and then fall into the placement box 303a. The inclined surface provided on the opposite surface of the fixed plate 301c and the movable plate 301d ensures that the suction head can remain in a vertical state when the distance between the fixed plate 301c and the movable plate 301d is continuously expanded, and then accurately falls into the guide member 302. Specifically, a weight sensing switch for detecting weight can be provided on the fixed plate 301c, and when the weight on it reaches the weight of 12 suction heads, the push rod motor 202 and the first motor 301f are triggered to operate. A time relay can be provided, and when the first motor 301f operates for a period of time, the suction head has fallen into the placement box 303a, and the second motor 303d is triggered to operate, and the guide rail seat 303c is pushed by one end distance by the cooperation of the screw rod 303e and the threaded hole 303b-1. After the push, the placement holes on the placement box 303a located directly below the guide member 302 are changed from a row full of suction heads to an empty row, and the boxes are loaded in sequence.

[0043] It should be noted that the device can be adjusted according to the specifications of the placement box 303a to adapt to placement boxes of various specifications. Specifically, the trigger weight of the weight sensing switch needs to be adjusted, and the length of the fixed plate 301c and the movable plate 301d and the length of the guide 302 and the number of compartments need to be matched and matched.
