Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a pipette tip boxing device. Background Technology

[0002] Pipette tips are critical consumables in biological laboratories and medical testing fields. They must be precisely arranged in a sterile state within standard tip boxes to meet the retrieval needs of pipetting equipment. Traditional boxing methods mainly rely on manual operation, which suffers from low efficiency, high labor costs, and susceptibility to contamination, making it difficult to meet the needs of large-scale industrial production.

[0003] Chinese Utility Model Patent Publication No. CN208161618U discloses a device for quickly installing pipette tips. The device includes a tip holder and an adjustment frame. Tip slots are sequentially arranged along the frame of the tip holder. The adjustment frame includes a flexible frame and horizontally arranged partitions between two parallel sides of the frame. In use, the adjustment frame is placed on the tip holder, with the partitions of the adjustment frame perpendicular to the tip slots of the tip holder. The side adjustment lever is pulled out of the positioning slot, and the tip falls into the small hole in the tip holder, completing the tip installation.

[0004] The aforementioned existing cartoning device has a complex structure and relies heavily on the side control levers. If any side control lever malfunctions, it will affect the rotation of the nozzle clip, thereby affecting the cartoning efficiency of the nozzle. Utility Model Content

[0005] To address the shortcomings of existing technologies, the present invention provides a pipette tip cartoning device that solves the problem of potential single-point failures in existing pipette cartoning devices, which could affect overall cartoning efficiency.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a pipette tip boxing device, including a shelf and an adjustment rack;

[0007] The shelf consists of a main frame made up of parallel front and rear longitudinal plates, which are hinged together by horizontal plates with equal spacing to form adjustable suction head receiving slots.

[0008] The adjustment frame is located below the shelf and consists of a base frame formed by a left horizontal plate and a right horizontal plate. The two are hinged together by a longitudinal plate with an equal spacing to the horizontal plate to form an adjustable box positioning structure.

[0009] The four corners of the shelf are hinged to the upper end of the cylinder, and the adjustment frame is fitted onto the cylinder through the fixing devices at the four corners, so that the shape formed by the shelf and the adjustment frame in the horizontal projection can be interchanged between a rhombus and a square.

[0010] The technical principle behind this solution is that, for rhombuses and squares with the same side length, the inscribed circle of the square has a larger diameter.

[0011] The beneficial effects of this solution are: 1. By rotating the shelf and the adjustment frame, the size of the rhombus inscribed circle formed by the horizontal projection of the shelf and the adjustment frame can be changed. The diameter of the suction head is larger than the diameter of the inscribed circle of the rhombus hole, but smaller than the diameter of the inscribed circle of the square. Therefore, by rotating the shelf and the adjustment frame, and thus adjusting the diameter of the inscribed circle of the horizontally projected rhombus, suction heads of different diameters can be adapted, which is highly flexible; 2. This device only has a shelf and an adjustment frame in its structure, which is simple and easier to maintain.

[0012] Furthermore, the hinge uses cylindrical pins. These cylindrical pins not only securely connect the front, rear, and transverse plates of the shelf, and the left, right, and longitudinal plates of the adjustment frame, but also serve as connecting pins, allowing the two connected components to rotate relative to each other.

[0013] Furthermore, the fixing device comprises a round bearing, a fixing tube, and a quick-release tube clamp; the inner ring of the round bearing is sleeved on the cylinder, allowing the adjusting frame to slide along the axial direction of the cylinder; an extended fixing tube is fixedly connected to the lower end of the inner ring of the round bearing; the quick-release tube clamp is held on the fixing tube, thereby fixing the sliding of the adjusting frame.

[0014] Furthermore, the fixing tube is made of rubber. Rubber is elastic and has high friction, which allows the adjusting bracket to be more stably fixed on the cylinder under the pressure of the quick-release tube clamp.

[0015] Furthermore, the circular bearing has a built-in locking device to fix the rotation of the adjustment bracket along the cylinder. The locking device prevents relative movement between the inner and outer rings of the circular bearing, thereby locking the rotation of the shelf and adjustment bracket along the cylinder axis. See Chinese Utility Model Patent Publication No. CN204716747U for a bearing with a locking device. Attached Figure Description

[0021] The following detailed description illustrates the specific implementation methods:

[0022] In the description of this utility model, it should be noted that the directions or positional relationships indicated by "front", "back", "left", "right", "up" and "down" are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device referred to must have a specific orientation.

[0023] As attached Figure 1-4 As shown:

[0024] A pipette tip packaging device includes a shelf and an adjustment rack;

[0025] The shelf is composed of a front longitudinal plate 11 and a rear longitudinal plate 12 arranged in parallel to form a main frame. The two are hinged together by transverse plates with equal spacing to form a suction head receiving slot with adjustable spacing.

[0026] The adjustment frame is located below the shelf and consists of a base frame formed by a left horizontal plate 21 and a right horizontal plate 22. The two are hinged together by a longitudinal plate with an equal spacing to the horizontal plate to form an adjustable box positioning structure.

[0027] The four corners of the shelf are hinged to the upper end of the cylinder 3, and the adjustment frame is fitted onto the cylinder 3 through the fixing devices at the four corners, so that the shape formed by the shelf and the adjustment frame in the horizontal projection can be interchanged between a rhombus and a square.

[0028] Furthermore, the hinge uses a cylindrical pin.

[0029] Furthermore, the fixing device comprises a round bearing 4, a fixing tube 41, and a quick-release tube clamp 5; the inner ring of the round bearing 4 is sleeved on the cylinder 3, allowing the adjusting frame to slide along the axial direction of the cylinder 3; an extended fixing tube 41 is fixedly connected to the lower end of the inner ring of the round bearing 4; the quick-release tube clamp 5 is clamped on the fixing tube 41, thereby fixing the sliding of the adjusting frame.

[0030] Furthermore, the fixing tube 41 is made of rubber.

[0031] Furthermore, the circular bearing 4 has a built-in locking device to fix the rotation of the adjustment frame along the cylinder 3.

[0032] Working principle:

[0033] Select a suction head box with rectangular suction head holes. Prepare a shelf and an adjustment rack with the same width as the cross and longitudinal clearance between the suction head holes. Place the shelf and adjustment rack on top of the suction head box, aligning the front longitudinal plate 11 of the shelf with one side of the suction head box. Adjust the angle between the shelf and the adjustment rack to be perpendicular. Check from above whether the centers of the square and circular suction head holes formed by the shelf and the adjustment rack are aligned.

[0034] Loosen the quick-release tube clamp 5 and move the adjustment frame downwards. When the lower surface of the adjustment frame is above the nozzle box and the distance between the upper surface of the adjustment frame and the upper surface of the shelf exceeds the length of the nozzle to be installed, clamp the quick-release tube clamp 5 to fix the adjustment frame so that the nozzle can be freely suspended on the shelf.

[0035] With the front longitudinal plate 11 of the shelf stationary, rotate the shelf and the adjustment rack along the cylinder 3 so that the horizontal projection of the shelf and the adjustment rack is a rhombus and the spacing between the horizontal plates of the shelf is less than the diameter of the suction head. Open the locking device of the four corner bearings 4 to lock the rotation of the bearings 4, thereby fixing the rotation of the shelf and the adjustment rack.

[0036] Place the vacuum cleaner nozzles randomly on the shelf, and shake the shelf to allow the smaller end of the nozzles to fall into the gaps between the nozzles. Tilt the shelf forward towards the front vertical plate 11 to slide the nozzles uniformly towards the front vertical plate 11.

[0037] Loosen the quick-release tube clamp 5 and move the adjustment bracket upwards along the cylinder 3 until it is flush with the shelf. Then clamp the quick-release tube clamp 5. At this point, the horizontal plate of the shelf and the vertical plate of the adjustment bracket form a diamond-shaped hole, and the suction head is located in the diamond-shaped hole. Since the diameter of the suction head is larger than the diameter of the inscribed circle of the diamond-shaped hole, the suction head will not fall into the diamond-shaped hole.

[0038] Close the locking device of the four corner bearings 4, rotate the shelf and the adjustment frame along the cylinder 3 so that the horizontal projection formed by the shelf and the adjustment frame is a square, and the diamond-shaped hole formed by the horizontal plate of the shelf and the vertical plate of the adjustment frame becomes a square hole. The suction head falls into the suction head box with the square hole under the action of gravity.

[0039] As the shelf and adjustment frame rotate to a perpendicular angle, the larger end of the suction head is suspended in the diamond-shaped hole formed by the shelf and adjustment frame. The horizontal rotational force on the suction head provides it with horizontal acceleration and a component force to resist gravity. Due to the small mass of the suction head, it will not fall off during the rotation of the shelf and adjustment frame to a perpendicular angle.

[0040] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
