Technical Field

[0001] The utility model belongs to the field of medical technology, and particularly relates to an automatic box packing machine for pipette tips. Background Art

[0002] In the field of medical development laboratory applications, pipettes are often used to manipulate laboratory samples in various laboratory operating procedures. The function of the pipette is to draw a certain volume of liquid into the pipette and then distribute the liquid into one or more distribution volumes. The pipette tip is a tool installed on the pipetting device of the pipette for aspirating and transferring liquids. It is the most commonly used consumable equipment in the laboratory.

[0003] At present, the most common way to pack pipette tips is to manually place the pipette tips into the pipette tip storage box. This packing method is labor-intensive and also reduces the packing rate. At the same time, the tip of the tip is relatively sharp and can easily scratch the limbs of the staff, posing certain safety hazards.

[0004] To this end, we provide a pipette tip automatic boxing machine to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic boxing machine for pipette tips, which can unload pipette tips in an orderly manner by arranging a combing component and a conveying component, and at the same time, the pipette tips to be determined are conveyed and organized into a storage box in sequence and in an orderly manner by the conveying component, without the need for manual storage, thus saving time and effort, and solving the problem of manual labor in placing pipette tips into a pipette tip storage box.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses an automatic box packing machine for pipette tips, comprising a working box and a storage box placed beside the working box; a conveying assembly is arranged on the inner wall of the working box; the conveying assembly comprises two turntables rotatably arranged on the inner wall of the working box; a rotating shaft is fixed on the side of the turntable away from the center; a limiting plate is fixed on the side of the rotating shaft; a connecting plate is arranged between the two rotating shafts; rotating holes symmetrically provided on the side of the connecting plate to cooperate with the rotating shaft for rotation; a vertical plate is arranged on the surface of the connecting plate; an arc plate is fixed on the surface of the vertical plate; a combing assembly is arranged on the surface of the working box; an inclined plate is fixed on the surface of the working box; baffles are fixed on both sides of the inclined plate.

[0008] The utility model is further configured that the combing component comprises a combing plate fixed on the surface of the working box and a feeding frame fixed on the surface of the combing plate; the feeding frame is configured to be gradually reduced in size from top to bottom.

[0009] The utility model is further configured that a passage groove is provided inside the combing plate; the passage groove is communicated with the feed frame; under the action of the passage groove, the passage groove only allows one pipette gun head to pass.

[0010] The utility model is further configured that a support plate is fixed on the side of the feed frame; a vibration motor is arranged on the surface of the support plate; under the action of the vibration motor, the pipette tips poured into the feed frame will be vibrated and fall in an orderly manner.

[0011] The utility model is further configured as follows: a placement plate is fixed on the side of the combing plate; an arc groove is opened on the surface of the placement plate; the arc groove is connected with the passage groove; a servo motor is fixed on the side of the working box; and the output end of the servo motor is fixedly connected to a turntable.

[0012] The utility model is further configured as follows: the arc-shaped plate is a hollow structure, and a plurality of suction holes are evenly opened on its surface; a connecting pipe is fixed to the side of the connecting plate; the connecting pipe and the suction holes are interconnected through the inside of the connecting plate; an air pump is placed next to the working box; and an air extraction pipe is connected between the connecting pipe and the air extraction pump.

[0013] The utility model is further configured as follows: a diverter plate is rotatably provided on the side of the working box; a lifting lug is fixed on the side of the diverter plate and a side of a limit plate; a steel wire rope is connected between the two lifting lugs; and a reset spring is connected between the diverter plate and the working box.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model transmits the pipette tips that have been sorted out in an orderly manner to the surface of the inclined plate one by one by arranging a conveying component. The pipette tips placed on the surface of the inclined plate roll down to the inside of the storage box through the inclined plate. At the same time, the provided air pump is conducive to better fixing the pipette tips during the conveying process. When the arc groove catches the pipette tips in the arc groove, the air pump is turned on to inhale air, so that the pipette tips are adsorbed and fixed. When the pipette tips are placed on the surface of the inclined plate, the air pump stops working. At this time, the pipette tips are separated from the arc plate and placed on the surface of the inclined plate. The whole process does not require manual operation, saving time and effort.

[0016] 2. The combing assembly provided in the utility model automatically arranges the pipette tips poured into the feed frame in an orderly manner and drops them one by one. Under the action of the passage groove, the passage groove only allows one pipette tip to pass through, so that only one pipette tip stays on the arc groove each time, thereby preventing too many pipette tips from being blocked and damaging the machine and the pipette tips during storage.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0028] See also Figure 1-5The utility model is an automatic box packing machine for pipette tips, comprising a working box 1 and a storage box 2 placed next to the working box 1; a conveying assembly 3 is arranged on the inner wall of the working box 1; the conveying assembly 3 comprises two turntables 4 rotatably arranged on the inner wall of the working box 1; a rotating shaft is fixed to the side of the turntable 4 away from the center; a limiting plate 5 is fixed to the side of the rotating shaft; a connecting plate 6 is arranged between the two rotating shafts; rotating holes that cooperate with the rotating shaft for rotation are symmetrically opened on the side of the connecting plate 6; a vertical plate 7 is arranged on the surface of the connecting plate 6; an arc plate 8 is fixed on the surface of the vertical plate 7; a combing assembly is arranged on the surface of the working box 1; an inclined plate 9 is fixed on the surface of the working box 1; baffles 10 are fixed on both sides of the inclined plate 9.

[0029] The operation process of this embodiment is as follows: first, put the pipette gun tip to be boxed into the combing component, and after the combing component, wait to be transported to the inclined plate 9 by the conveying component 3. In the initial state, the rotating shaft is at the lowest position of the turntable 4, driving one turntable 4 to rotate clockwise, and driving the other turntable 4 to rotate synchronously clockwise through the connecting plate 6, thereby driving the vertical plate 7 and the curved plate 8 to rotate synchronously clockwise. When the rotating shaft rotates to the leftmost position of the turntable, the curved plate 8 just contacts with a pipette gun tip to be boxed. As the turntable 4 continues to rotate, the pipette gun tip is lifted and taken away. When the rotating shaft is at the rightmost position of the turntable 4, the pipette gun tip just contacts with the inclined plate 9. As the turntable 4 rotates, the curved plate 8 separates from the pipette gun tip and falls into the storage box 2 along the inclined plate. No manual operation is required, saving time and effort. Specific embodiment 2

[0031] See also Figure 1-5 On the basis of the specific embodiment 1, the combing assembly includes a combing plate 11 fixed on the surface of the working box 1 and a feed frame 12 fixed on the surface of the combing plate 11; the feed frame 12 is arranged to be gradually reduced in size from top to bottom.

[0032] Specifically, a passage groove 13 is provided inside the combing plate 11 ; the passage groove 13 is connected to the feed frame 12 ; under the action of the passage groove 13 , the passage groove 13 only allows one pipette tip to pass through.

[0033] Furthermore, a support plate 14 is fixed to the side of the feed frame 12; a vibration motor 15 is arranged on the surface of the support plate 14; under the action of the vibration motor 15, the pipette tips poured into the feed frame 12 will be vibrated and fall down in an orderly manner.

[0034] Furthermore, a placement plate 16 is fixed to the side of the combing plate 11; an arc groove 17 is opened on the surface of the placement plate 16; the arc groove 17 is connected to the passage groove 13; a servo motor is fixed to the side of the working box 1; and the output end of the servo motor is fixedly connected to a turntable 4.

[0035] The operation process of this embodiment is as follows: manually put the pipette tips to be sorted into the feed frame 12, turn on the vibration motor 15 to vibrate the feed frame 12 to prevent the pipette tips from piling up inside the feed frame 12, and the pipette tips pass through the passage slot 13 one by one in a single row and finally stay in the arc slot 17, then turn on the servo motor to drive a turntable 4 to rotate clockwise, drive another turntable 4 to rotate synchronously clockwise through the connecting plate 6, and then drive the vertical plate 7 and the arc plate 8 to rotate synchronously clockwise. When the shaft rotates to the leftmost position of the turntable, the arc plate 8 just contacts a pipette tip to be boxed. As the turntable 4 continues to rotate, the pipette tip is lifted and taken away. When the shaft is at the rightmost side of the turntable 4, the pipette tip just contacts the inclined plate 9. As the turntable 4 rotates, the arc plate 8 separates from the pipette tip and falls into the storage box 2 along the inclined plate. The combing component automatically arranges the pipette tips poured into the feed frame 12 in an orderly manner and falls one by one. Under the action of the passage groove 13, the passage groove 13 only allows one pipette tip to pass, so that there is only one pipette tip staying on the arc groove 17 at a time, preventing too many pipette tips from being blocked and damaging the machine and the pipette tips during storage. Specific embodiment three

[0037] See also Figure 1-5 On the basis of the specific embodiment 1 and the specific embodiment 2, the arc plate 8 is a hollow structure, and a plurality of suction holes 18 are evenly opened on its surface; a connecting pipe 19 is fixed to the side of the connecting plate 6; the connecting pipe 19 and the suction holes 18 are interconnected through the inside of the connecting plate 6; an air pump 20 is placed next to the working box 1; an air extraction pipe 21 is connected between the connecting pipe 19 and the air extraction pump 20.

[0038] Specifically, a diverter plate 22 is rotatably provided on the side of the working box 1; ears 23 are fixed on the side of the diverter plate 22 and the side of a limit plate 5; a wire rope is connected between the two ears 23; and a return spring 24 is connected between the diverter plate 22 and the working box 1.

[0039] The operation process of this embodiment is as follows: in order to prevent the pipette tip from falling during the transmission process, an air pump is used to fix it, and the air pump 20 is turned on to allow the air pump 20 to suck air through the suction hole 18, the connecting tube 19 and the air suction tube 21, so that the pipette tip is sucked and fixed, and the pipette tip that falls through the inclined plate 9 can be evenly received in the storage box 2 by the diverter plate 22. In the process of the turntable 4 rotating to drive the rotating shaft and the limit plate 5 to rotate, the steel wire rope pulls the diverter plate 22, and the elastic force of the return spring 24 pushes the diverter plate 22, that is, the diverter plate 22 can be rotated left and right, so that the pipette tip can be evenly laid left and right inside the storage box 2, and the boxing is more orderly.
