[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following is combined Figure 1 This invention describes an automatic pipette tip recovery device.

[0023] like Figure 1 As shown, the automatic pipette tip recycling device of this utility model embodiment includes: a conveyor line 1, a sorting plate 2, and a recycling box 3.

[0024] Specifically, the sorting plate 2 is inclined and located at the end of the conveyor line 1. In this way, the gun head 6 conveyed on the conveyor line 1 can be moved to the sorting plate 2. Furthermore, due to the inclined arrangement of the sorting plate 2, the gun head 6 can move along the length of the sorting plate 2 under the action of its gravity.

[0025] In practical applications, the sorting plate 2 is sequentially equipped with multiple sorting areas, each with a discharge hole 21 and a corresponding recycling box 3 below it. The size of the discharge holes 21 corresponding to the sorting areas gradually increases along the direction away from the conveyor line 1. The pipette tips 6 used in the pipette 5 include approximately 1-2 mL tips, 5 mL tips, and 10 mL tips. Thus, the sorting plate 2 can have three sorting areas, arranged sequentially along its length. The first sorting area, closest to the conveyor line 1, is used to sort 1-2 mL tips, the second for 5 mL tips, and the third for 10 mL tips.

[0026] In addition, a first recycling box 3 is located below the first sorting area, allowing 1-2 mL pipette tips 6 to fall through the discharge hole 21 of the first sorting area into the first recycling box 3. A second recycling box 3 is located below the second sorting area, allowing 5 mL pipette tips 6 to fall through the discharge hole 21 of the second sorting area into the second recycling box 3. A third recycling box 3 is located below the third sorting area, allowing 10 mL pipette tips 6 to fall through the discharge hole 21 of the third sorting area into the third recycling box 3. It should be noted that the discharge hole 21 of the first sorting area needs to be compatible with 1-2 mL pipette tips 6, the discharge hole 21 of the second sorting area needs to be compatible with 5 mL pipette tips 6, and the discharge hole 21 of the third sorting area needs to be compatible with 10 mL pipette tips 6.

[0027] Specifically, after use, the pipette tips are placed on conveyor line 1. Driven by conveyor line 1, the pipette tips move towards and onto sorting plate 2. Under the influence of gravity, the pipette tips move along the length of sorting plate 2. During this process, the pipette tips fall into the corresponding recycling bin 3 through the corresponding drop hole 21, thus completing the sorting and recycling of the pipette tips. This method can replace the current manual recycling method, improve the sorting and recycling speed of the pipette tips 6, effectively solve the problem of rapid sorting, reduce workload, and improve work efficiency.

[0028] like Figure 1 As shown, the conveyor line 1 is inclined, and the inclination angle of the conveyor line 1 is the same as the inclination angle of the sorting plate 2. For example, the inclination angles of both the conveyor line 1 and the sorting plate 2 can be 3° to 5°. This ensures that the pipette tip moves stably and slowly on both the conveyor line 1 and the sorting plate 2, while also ensuring that the pipette tip on the conveyor line 1 moves smoothly to the sorting plate 2. In practical applications, the conveying plane of the conveyor line 1 and the bearing plane of the sorting plate 2 are on the same horizontal plane. Here, the conveying plane refers to the plane on the conveyor line 1 where the pipette tip is located, and the bearing plane refers to the plane on the sorting plate 2 where the pipette tip is located.

[0029] In an alternative embodiment, such as Figure 1 As shown, the length direction of the discharge hole 21 is the same as the width direction of the sorting plate 2. The discharge hole 21 can be a rectangular hole, so that when the pipette tip is placed horizontally on the sorting plate 2, the pipette tip can fall into the corresponding recycling box 3 through the discharge hole 21.

[0030] It should be noted that when the pipette tip rolls on the sorting plate 2, since the length direction of the discharge hole 21 is the same as the width direction of the sorting plate 2, the pipette tip can quickly fall into the corresponding recycling box 3 through the discharge hole 21.

[0031] In optional embodiments, such as Figure 1 As shown, the automatic pipette tip recovery device also includes a pipette holder 4, which includes a connected support leg 41 and a support frame 42. The support frame 42 is located above the conveyor line 1, and the pipette 5 is placed in conjunction with the support frame 42.

[0032] It should be noted that there can be two support legs 41, with the two support legs 41 located on both sides of the conveyor line 1. The support frame 42 is connected to the two support legs 41, spans the conveyor line 1, and is located above the conveyor line 1. In addition, the support frame 42 is provided with a clamping part for holding the pipette 5. For example, the clamping part is a structural member with a semi-circular groove.

[0033] In optional embodiments, such as Figure 1 As shown, the automatic pipette tip recovery device also includes a collection cylinder 7. The collection cylinder 7 has a receiving space and an inlet and an outlet communicating with the receiving space. The collection cylinder 7 is mounted on the support leg 41, with the inlet corresponding to the support frame 42, and the outlet located near the conveyor line 1. It should be noted that the collection cylinder 7 can be configured to be larger at the top and smaller at the bottom, with the inlet size larger than the outlet size, and the inner diameter of the receiving space gradually decreasing from the inlet to the outlet. The collection cylinder 7 can be made of plastic.

[0034] In practical applications, after the pipette tip 6 of the pipette 5 located on the support frame 42 is removed, it can be moved to the conveyor line 1 via the collection tube 7. In other words, the movement of the pipette tip is constrained by the collection tube 7, so that the pipette tip can be moved to the conveyor line 1 and prevented from falling.

[0035] In an optional embodiment, the automatic pipette tip retrieval device further includes a robotic arm configured to remove the pipette tip 6 from the support frame 42 and move it onto the transport line 1.

[0036] It should be noted that the robotic arm may include a three-dimensional movement mechanism and a gripping mechanism. The three-dimensional movement mechanism can realize three-dimensional movement, and the gripping mechanism can use a clamping or suction method to grip the gun head 6. The robotic arm in question is a conventional robotic arm and will not be described in detail here.

[0037] In practical applications, after the robotic arm removes the pipette tip 6 from the support frame 42, it moves the tip 6 to the collection cylinder 7, allowing the tip 6 to move to the conveyor line 1 via the collection cylinder 7. Driven by the conveyor line 1, the pipette tip moves toward the sorting plate 2 and onto the sorting plate 2. Under the influence of gravity, the pipette tip moves along the length of the sorting plate 2. During this process, the pipette tip falls into the corresponding recycling box 3 through the corresponding drop hole 21, thus completing the sorting and recycling of the pipette tip.

[0038] In optional embodiments, such as Figure 1 As shown, to improve sorting efficiency, each sorting area is provided with multiple discharge holes 21, and the discharge holes 21 in the same sorting area are of the same size. The multiple discharge holes 21 in each sorting area are arranged in a rectangular array. For example, along the width direction of the sorting plate 2, the first sorting area has three rows of discharge holes 21, the second sorting area has two rows of discharge holes 21, and the third sorting area has one row of discharge holes 21.

[0039] In practical applications, conveyor line 1 includes a driving component, a driving wheel, a driven wheel, and a conveyor belt. The conveyor belt is fitted over the driving wheel and the driven wheel, and the driving component is connected to the driving wheel via a transmission. The driving component can be a drive motor.

[0040] Specifically, when the drive motor starts, its output drives the drive wheel to rotate via a transmission assembly. The rotational motion of the drive wheel is transmitted to the driven wheel via the conveyor belt, causing the driven wheel to rotate as well. Under the combined action of the drive and driven wheels, the conveyor belt begins to move continuously. The gun head 6 is conveyed to the designated position as the conveyor belt moves. When it is necessary to stop conveying, the drive motor stops working, and the drive wheel stops rotating. Due to the inertia and friction of the conveyor belt, the conveyor belt gradually decelerates and eventually stops moving.

[0041] In optional embodiments, such as Figure 1 As shown, to prevent the gun head 6 from falling off during movement, a first baffle 11 is provided at the edge of the conveyor line 1. Exemplarily, both sides of the conveyor line 1 are provided with the first baffle 11. Furthermore, both sides and the tail edge of the sorting plate 2 are provided with second baffles 22. Thus, the second baffle 22 is generally U-shaped, and the first baffle 11 and the second baffle 22 are connected, so the entire baffle is also U-shaped.

[0042] In practical applications, the automatic pipette tip recovery device may also include a base plate 8, on which the conveyor line 1, sorting plate 2, and recovery box 3 can all be mounted. For example, the sorting plate 2 can be mounted to the base plate 8 using multiple support plates.

[0043] It is particularly noteworthy that the automatic pipette tip recycling device may also include a control motherboard, with the drive motors of the robotic arm and conveyor line 1 electrically connected to the control motherboard. Specifically, upon receiving a command from the control motherboard, the robotic arm removes the pipette tip 6 from the support frame 42 and moves it to the collection cylinder 7, allowing the tip 6 to move to the conveyor line 1 via the collection cylinder 7. Simultaneously, the control motherboard controls the drive motor to move, and under the drive of the conveyor belt, the pipette tip moves towards the sorting plate 2 and onto it. Under the influence of gravity, the pipette tip moves along the length of the sorting plate 2. During this process, the pipette tip falls into the corresponding recycling box 3 through the corresponding drop hole 21, thus completing the sorting and recycling of the pipette tip. Finally, the inspector simply removes the recycling box 3 and sends the tip 6 for cleaning or disposal.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
