Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, and in particular to a suction tip carrier device for non-stop replacement. Background Technology

[0002] Fully automated analyzers, characterized by their speed, efficiency, and high accuracy, have found widespread application in the medical diagnostics field. Sample testing typically employs a batch processing method. Specifically, pipette tips are grouped and mounted on tip holders, which are then inserted into a support frame. After the support frame is pushed into the instrument's consumables compartment, batch sampling and testing can begin. Once the previous batch of tips is used up, simply pull out the support frame and replace the tip holder for the next round of testing. In this process, sampling is performed using a pipette connected to a 3D robotic arm. To facilitate the pipette's operation, the support frame is usually fixed in the instrument's consumables compartment. Therefore, the machine must be stopped to release the support frame and replace the tip holder. This process not only increases manual labor but also disrupts the continuity of testing and reduces equipment efficiency. Secondly, with the support frame fixed, the pipette tip holder is usually placed directly on the support frame for easy replacement. When there is a deviation between the pipette and the tip positioning, the pipette tip holder can easily be pulled off course or lifted up, affecting subsequent sampling operations and causing equipment failure. Summary of the Invention

[0003] To solve the above problems, this utility model provides a suction head carrying device for non-stop replacement, specifically adopting the following technical solution:

[0004] The non-stop replacement suction head support device of this utility model includes a suction head frame and a support frame. The suction head frame includes a support plate with a plurality of insertion holes arranged in a rectangular dot matrix. The periphery of the support plate is provided with a plurality of protective plates at intervals. Each protective plate extends from the support plate to the top and bottom respectively. The periphery of the support plate is also provided with a torsion buckle located between adjacent protective plates. The bottom of the support plate is provided with a socket plate located outside the area where the insertion holes are located. The socket plate is located inside the protective plates and is spaced apart from the protective plates. The support frame includes a base and a support plate connected by support legs. One end of the support plate is provided with a handle. The other end of the support plate is provided with a receiving hole adapted to the socket plate. The outer edge of the support plate outside the receiving hole is provided with a locking clip adapted to the torsion buckle. The base is provided with a positioning magnetic suction assembly.

[0005] The support plate is a rectangular structure with chamfered corners at all four corners. The guard plate is divided into two sections, each of which adopts a U-shaped structure and is symmetrically arranged along the center of the support plate.

[0006] The guard plate includes an upper section and a lower section located on both sides of the bearing plate, wherein the thickness of the lower section is greater than the thickness of the upper section.

[0007] The socket plate is configured as a closed rectangular structure with chamfered corners around the area where the insertion hole is located, and the lower edge of the socket plate is set lower than the lower edge of the protective plate.

[0008] The torsion buckle is symmetrically arranged along the center of the support plate, including a fulcrum integrated with the support plate. The fulcrum extends upward to form a pressing handle, and extends downward to form a hook head with the hook tip pointing inward.

[0009] The base is provided with a hollow hole corresponding to the position of the receiving hole. The base outside the hollow hole and the support plate outside the receiving hole are both provided with countersunk holes. Bolts for connecting the support leg to the base and the support plate are provided in the countersunk holes.

[0010] The outer edge of the support plate is provided with a groove corresponding to the position of the torsion buckle, and a protrusion structure is provided in the groove as the locking clip.

[0011] The positioning magnetic suction assembly includes a recessed groove on the edge of the chassis, a magnetic suction element is disposed in the recessed groove, and a pressure plate is disposed above the magnetic suction element. The pressure plate is connected to the chassis by screws.

[0012] The positioning magnetic suction component is located at one end of the chassis away from the handle.

[0013] This utility model provides a non-stop pipette tip replacement device. By incorporating a strong magnetic structure at the bottom of the support frame, it achieves positioning and correction of the support frame, allowing for tip replacement without shutting down the system. The tip holder features a stepped structure at its bottom for easy positioning and installation with the support frame. Additionally, twist-lock buckles on both sides of the tip holder allow for convenient locking / unlocking with the support frame via pressing. This prevents the tip holder from being pulled off course or lifted when the pipette is not accurately positioned, and also meets the requirements for rapid tip replacement. This utility model has a simple structure, is easy to use, has a low failure rate, and enables non-stop tip replacement, improving equipment testing efficiency. Attached Figure Description

[0017] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0018] like Figure 1-3 As shown, the non-stop replacement suction head carrying device of this utility model includes a suction head frame and a support frame. The suction head M is directly mounted on the suction head frame, which is then mounted on the support frame. By pushing or pulling the support frame, the suction head frame can be moved in or pulled out from the consumables compartment, thereby enabling the replenishment or batch replacement of the suction heads M.

[0019] Specifically, the suction head holder is a disposable consumable made of PP material, including a support plate 11, a protective plate 12, a socket plate 13, and a twist buckle 14. In this embodiment, the support plate 11 adopts a rectangular structure with chamfered corners, and has several insertion holes N, all of which are round holes of the same size, arranged in a rectangular dot matrix structure. Two spaced-apart protective plates 12 are provided around the periphery of the support plate 11. Each protective plate 12 extends from the short side of the support plate 11 to the long sides on both sides, forming a U-shaped structure symmetrically arranged along the center of the support plate 11. Each protective plate 12 includes an upper section extending upwards from the support plate 11 and a lower section extending downwards. Since the suction head holder is supported on the support frame by the protective plates 12, the thickness of the lower section of the support plate 11 is greater than the thickness of the upper section to improve support stability. To securely connect the suction head to the support frame, a socket plate 13 is provided at the bottom of the support plate 11. Simultaneously, a torsion buckle 14 is provided in the gap between the guard plates 12 around the perimeter of the support plate 11. The socket plate 13 is located inside the guard plate 12 and spaced apart from it. It is a closed rectangular structure with chamfered corners, surrounding the outer edge of the area where the insertion hole N is located, and the lower edge of the socket plate 13 is lower than the lower edge of the guard plate 12. There are two torsion buckles 14, both located at the center of the long side of the support plate 11 (i.e., symmetrically arranged along the center of the support plate 11). Each buckle includes a fulcrum 141 integrated with the support plate 11. The fulcrum 141 extends upward to form a pressing handle 142, and extends downward to form a hook head 144 with an inwardly pointing hook tip 143.

[0020] Because the suction head M has a certain length, the support frame adopts a matching aluminum alloy frame structure, including a base 22 connected by legs 21 and a support plate 23. One end of the support plate 23 has a recessed handle 24 for easy pushing and pulling of the support frame; the other end of the support plate 23 has a receiving hole 25 that matches the receiving plate 13, allowing the suction head frame to be securely inserted into the support plate 23 through the cooperation of the receiving plate 13 and the receiving hole 25. The outer edge of the support plate 23 also has grooves corresponding to the positions of the torsion buckle 14, and each groove has a protrusion structure corresponding to the position of the hook 144. This protrusion structure serves as a locking clip 26 that cooperates with the hook 144. To reduce wear and tear on the support frame during the pulling process, the base 22 adopts a hollow structure made of ABS material. Specifically, hollow holes 27 are provided at positions corresponding to the receiving hole 25. Countersunk holes 28 are provided on the base 22 at the four outer corners of the hollow holes 27 and on the support plate 23 at the four outer corners of the receiving hole 25. The support legs 21 are inserted into the countersunk holes 28, and the support legs 21, base 22, and support plate 23 are connected together by bolts 29 installed in the countersunk holes 28. In addition, a positioning magnetic suction assembly 4 is provided on the base 22. This positioning magnetic suction assembly 4 is located at the end of the base 22 away from the handle 24, and includes a recess 41 formed on the edge of the base 22. A magnetic suction element 42 is installed in the recess 41, and a pressure plate 43 is provided above the magnetic suction element 42. The pressure plate 43 is connected to the base 22 by screws 44 (or by adhesive).

[0021] In use, place the suction tip holder above the support frame, align the insert plate 13 with the receiving hole 25 of the support plate 23, and push it downwards. Simultaneously, press the pressing handle 142 of the twisting buckle 14 to open the hook 14. When the insert plate 13 is installed in the receiving hole 25 and the bottom of the guard plate 12 is in contact with the surface of the support plate 23, release the pressing handle 142. The hook 144 will then engage with the locking clip 26 of the support plate 23, locking the suction tip holder to the support frame. Afterwards, push the support frame into the instrument. Due to the positioning and correction effect of the positioning magnetic suction component 4, the support frame is attracted to the consumables position, ensuring proper placement and facilitating subsequent suction tip retrieval. When the suction head is used up, overcome the magnetic attraction of the positioning magnetic component 4, pull out the support frame, press the pressing handle 142 of the twist buckle 14 again to release the locking relationship between the suction head frame and the support frame, place the new suction head frame on the support frame and lock it, then push it back into the consumables slot to retrieve the suction head. Repeat this cycle.
