Description

Technical Field

[0001] This utility model relates to the field of box sorting technology, and in particular to an automatic box sorting device for pipette tips. Background Technology

[0002] Pipette tips are disposable plastic pipette tips used in pipettes, primarily for the accurate and precise dispensing of liquids. They come in various sizes and shapes to suit different types of pipettes and are widely used in basic laboratory research, clinical diagnostics, and other fields. During the pipette tip manufacturing process, pipette tips need to be neatly arranged and loaded into tip boxes.

[0003] Currently, some methods involve manual arrangement of pipette tips. However, due to the small size of the tips and the need for precise arrangement, prolonged manual operation can easily lead to fatigue. Under fatigue, incorrect or missing pipette tips are prone to occur, such as mixing different sizes or omitting a tip from a particular orifice, which can affect product quality. Other methods use automated vibratory trays to arrange the tips on a track through vibration. However, this method has several problems. Since pipette tips are usually made of soft plastic, they can easily deform during vibration due to collisions, affecting their sealing and accuracy in subsequent use.

[0004] Based on the above situation, we propose an automatic pipette tip sorting device to solve the above problems. Utility Model Content

[0005] This invention provides an automatic pipette tip sorting device to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: An automatic pipette tip sorting device includes a fixing mechanism, a delivery unit, and a storage plate. The fixing mechanism is connected to a clamping assembly with multiple clamping holes for moving the tip body to a tip-down position for delivery. The delivery unit includes multiple delivery lines located below the clamping assembly for receiving the tip body on the fixing mechanism. The storage plate has multiple storage boxes arranged in a rectangular array, and the lower end of the storage plate is driven to move by a shifting mechanism to drop the tip body in the delivery line into the storage box.

[0007] Preferably, the input ends of the plurality of conveying pipelines correspond one-to-one with the plurality of clamping holes.

[0008] Preferably, the distribution shape of the input ends of the plurality of conveying pipes on a first projection plane perpendicular to their preset extension direction is the same as the distribution shape of the output ends of the plurality of conveying pipes on a second projection plane perpendicular to their preset extension direction.

[0009] Preferably, the number of storage boxes on the storage plate is the same as the number of delivery pipes.

[0010] Preferably, the shifting mechanism includes: A first linear drive mechanism is provided with a first connecting plate for driving the first connecting plate to translate along the X-axis direction; The second linear drive mechanism is disposed on the first connecting plate, and the second linear drive mechanism is provided with a second connecting plate connected to the storage plate. The storage plate is disposed on the second connecting plate and is used to drive the storage plate to translate along the Z-axis direction orthogonal to the X-axis. The controller is electrically connected to the first linear drive mechanism and the second linear drive mechanism respectively, and is used to receive motion commands and output control signals to enable the storage plate to translate in the plane formed by the XZ axes.

[0011] Preferably, the storage box is detachably connected to the slot of the storage plate via elastic claws on both sides.

[0012] The beneficial effects of this utility model are as follows: By setting a fixing mechanism with a clamping component having multiple clamping holes, the main body of the suction head can be arranged in a state with the tip facing down, waiting for delivery. This ensures the uniformity of the initial posture of the suction head during delivery and avoids misassembly caused by posture confusion during subsequent box arrangement. The multiple delivery pipes of the delivery unit correspond one-to-one with the clamping holes, enabling orderly reception and delivery of the suction heads. At the same time, the distribution shape of the input and output ends of the delivery pipes on the corresponding projection plane is the same, ensuring the consistency of the distribution shape of the suction heads during delivery and reducing positional deviation during box arrangement. The number of storage boxes in the rectangular array on the storage plate is the same as the number of delivery pipes. In conjunction with the shifting mechanism composed of the first linear drive mechanism, the second linear drive mechanism, and the controller, the storage plate can be driven to accurately translate in the XZ axis plane, realizing the accurate drop and arrangement of the suction heads from the delivery pipes to the storage boxes, improving the box arrangement accuracy and efficiency.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] Reference Figures 1-4 As shown, an automatic pipette tip sorting device includes a fixing mechanism 1. A clamping assembly 3 with multiple clamping holes 2 is connected to the fixing mechanism 1 to move the pipette tip body to a tip-down position for delivery. The clamping assembly 3 can be three stacked plates, each with clamping holes 2. When the three plates are stacked, the clamping holes 2 overlap. When the middle plate is misaligned, the clamping holes 2 on the upper and lower plates coincide. The pipette tip body is fixed by the misalignment between the clamping holes 2 on the middle plate and the upper and lower plates, and the pipette tip body is moved to a tip-down position for delivery. Below the clamping assembly 3, there is a delivery unit 4, which includes multiple delivery lines 5 for receiving pipette tips that fall from the clamping unit. Furthermore, a storage plate 6 is provided below the output end of the conveying pipeline 5. Multiple storage boxes 7 are arranged in a rectangular array on the storage plate 6, and the lower end of the storage plate 6 is driven to move by the shifting mechanism 8, so that the suction head body in the conveying pipeline 5 falls into the storage box 7. Specifically, when the clamping mechanism releases its grip on the suction head body, the suction head body falls through the conveying pipeline 5 into the storage box 7 below. Then the clamping assembly 3 clamps the suction head body conveyed from upstream again to continue conveying. For example, the shifting mechanism 8 first drives the storage plate 6 to move along the X-axis, so that the suction head body falls into another hole in the storage box 7. When the suction head bodies in the X-axis direction of the storage box 7 are all filled, the shifting mechanism 8 drives the storage plate 6 to move in the Z-axis direction. This process is repeated until each storage box 7 is filled with suction head bodies.

[0018] Reference Figures 1-2As shown, furthermore, the input ends of multiple delivery pipes 5 correspond one-to-one with multiple clamping holes 2. As shown in the figure, the clamping holes 2 can be distributed in a 4×8 rectangular array. The delivery pipes 5 are also 32 transparent PVC delivery pipes distributed in a 4×8 rectangular array. Their input ends are connected to the outlets of the clamping holes 2 one-to-one through conical guide sleeves to ensure that the suction head falls without jamming. When the clamping hole 2 is aligned with the input end of the delivery pipe 5, 32 suction head bodies are delivered at one time.

[0019] Reference Figures 1-2 As shown, the distribution shape of the input ends of the multiple conveying pipes 5 on the first projection plane perpendicular to their preset extension direction is the same as the distribution shape of the output ends of the multiple conveying pipes 5 on the second projection plane perpendicular to their preset extension direction. The number of storage boxes 7 on the storage plate 6 is the same as the number of conveying pipes 5. The mounting holes on the storage boxes 7 are also distributed in a 4×8 rectangular array. If the clamping holes 2 and the conveying pipes 5 are both distributed in a 4×8 rectangular array, then the storage boxes 7 on each storage plate 6 are also distributed in a 4×8 rectangular array. In this way, when the clamping component 3 feeds 32 times, the shifting mechanism 8 drives the storage plate 6 to shift in the rectangular array direction 32 times, so that the storage boxes 7 on each storage plate 6 can be filled with the suction head body.

[0020] Reference Figure 3As shown, the shifting mechanism 8 further includes a first linear drive mechanism 801, a second linear drive mechanism 803, and a controller 805. The first linear drive mechanism 801 has a first connecting plate 802 for driving the first connecting plate 802 to translate along the X-axis. The second linear drive mechanism 803 is mounted on the first connecting plate 802 and has a second connecting plate 804 connected to the receiving plate 6. The receiving plate 6 is mounted on the second connecting plate 804 for driving the receiving plate 6 to translate along the Z-axis, which is orthogonal to the X-axis. The controller 805 is electrically connected to both the first linear drive mechanism and the second linear drive mechanism 803, and is used to receive motion commands and output control signals to cause the receiving plate to translate. The storage plate 6 performs translational motion within the plane formed by the X and Z axes. Specifically, the first linear drive mechanism 801 can be a linear motor or a ball screw slide, with its fixed end mounted on the equipment frame and its moving end rigidly connected to the first connecting plate 802. When the first linear drive mechanism 801 is working, it can drive the first connecting plate 802 to move smoothly along the X-axis direction (such as the length direction of the equipment). The second linear drive mechanism 803 also uses a linear motor or a high-precision synchronous belt module, with its fixed end integrated on the first connecting plate 802 and its moving end fixed to the bottom surface of the storage plate 6 via the second connecting plate 804. It can drive the storage plate 6 to move along the Z-axis direction (such as the width direction of the equipment) which is orthogonal to the X-axis. The controller 805 uses a PLC. Alternatively, a motion control card can receive the box placement command from the host computer through a preset program, and then output pulse signals to the first and second linear drive mechanisms 803 respectively to control their movement speed, displacement, and start / stop sequence, so that the storage plate 6 can complete the translation in the plane formed by the XZ axes according to a preset trajectory (such as moving row by row or column by column), ensuring that the hole position of each storage box 7 can accurately connect with the output end of the conveying pipeline 5.

[0021] Reference Figure 4 As shown, the storage box 7 is further detachably connected to the slot of the storage plate 6 by the elastic claws 9 on both sides. The elastic claws 9 are used to lock the storage box 7 on both sides of the slot of the storage plate 6, thereby fixing the storage box 7 and achieving stability when the suction head body is inserted.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
