Description

Technical Field

[0001] This utility model relates to the field of reagent tube handling technology, and in particular to a reagent tube handling device. Background Technology

[0002] In fields such as medical testing, biological experiments, and chemical analysis, reagent tubes are key containers for carrying samples or reagents. The stability, efficiency, and safety of their handling operations directly affect the reliability of experimental results and the smoothness of the production process. With the development of automation technology, the traditional manual handling of reagent tubes is gradually being replaced by automated handling equipment due to problems such as low efficiency, easy contamination, and high labor intensity.

[0003] Existing reagent tube handling equipment mostly uses a single fixing method to grasp and move reagent tubes, such as using only a negative pressure adsorption mechanism or a mechanical clamping mechanism. If only negative pressure adsorption is used, slight air leakage in the adsorption channel or stains on the outer wall of the reagent tube can easily lead to insufficient adsorption force, causing the reagent tube to fall. This may not only cause sample loss but also pose a risk of environmental pollution after breakage. If only mechanical clamping is used, it is difficult to precisely control the clamping force. Excessive force can cause the reagent tube to deform or break, while insufficient force cannot guarantee the stability during handling. Especially when the equipment moves or turns, the reagent tube is prone to shaking or even falling off. To solve the above problems, this application proposes a reagent tube handling device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reagent tube handling device. Through the coordinated action of an adsorption mechanism and a clamping mechanism, the reagent tube is first initially fixed by negative pressure adsorption, and then further stabilized by mechanical clamping. This effectively avoids the problems of falling, deformation, or breakage that are prone to occur in single fixing methods, and ensures that the reagent tube remains stable during movement, turning, and other processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reagent tube handling device includes a robotic arm connector.

This effectively avoids the problems of falling, deformation or breakage that are prone to occur in single fixing methods, and ensures that the reagent tube remains stable during movement, turning and other processes.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4A reagent tube handling device includes a robotic arm connector 1, which connects to an external robotic arm to enable overall movement and positioning of the device. A square plate 2 is fixedly connected to the bottom of the robotic arm connector 1, supporting the connector and providing a mounting base for multiple support frames 3 below. Multiple support frames 3 connect the square plate 2 to a fixed plate 4, providing support and fixation. The fixed plate 4 provides a guide for the sliding of sliding rods 5 and a mounting carrier for a power component 8. Multiple sliding rods 5 are slidably connected to the fixed plate 4, restricting the base plate 7 to move only vertically and ensuring stability. A frame plate 6 connects the tops of the sliding rods 5, limiting their movement and preventing them from veering off the fixed plate. The fixed plate 4 is detached, and the bottom of multiple sliding rods 5 is fixedly connected to a base plate 7. The base plate 7 connects to the bottom of multiple sliding rods 5, providing an installation platform for the vertical rods 9 and the clamping mechanism, and moves synchronously with the sliding rods 5. The bottom of the fixed plate 4 is fixedly connected to multiple power components 8, which include a pressing cylinder and multiple guide cylinders. The positions of the multiple power components 8 are set in a rectangle and arranged at the four corners of the base plate 7. The output ends of the multiple power components 8 are fixedly connected to the top of the base plate 7. The multiple power components 8 work together to drive the base plate 7 to move up and down along the guide direction of the sliding rods 5. The pressing cylinder provides the main driving force, and the guide cylinders help to maintain smooth movement. The top of the base plate 7 is fixedly connected to multiple vertical rods 9, which are used to connect the base plate 7 and the limiting plate 10, support the limiting plate 10 and make it move synchronously with the base plate 7. The multiple vertical rods 9 are fixedly connected to the limiting plate 10, which provides an installation position for the adsorption mechanism and plays a role in fixing and limiting the adsorption mechanism.

[0019] The limiting plate 10 is equipped with multiple adsorption mechanisms, each including a cylindrical body 11 that penetrates and is fixedly connected to the limiting plate 10. The cylindrical body 11 connects the placement cylinder 12 and the gas delivery pipe, providing an upper channel for the guide groove 13. The bottom of the cylindrical body 11 is fixedly connected to the placement cylinder 12, which, together with the cylindrical body 11, forms the guide groove 13, providing initial containment and guidance for the reagent tube body 14. The cylindrical body 11 and the placement cylinder 12 share a common, interconnected guide groove 13, which provides space for the reagent tube body 14. The reagent tube body 14 is guided to accurately enter the adsorption position. The reagent tube body 14 is placed in the guide groove 13. The reagent tube body 14 is the object to be transported by the equipment. Stable transportation is achieved through the accommodation of the guide groove 13 and subsequent adsorption and clamping. The top of the fixing plate 4 is fixedly connected to the vacuum generator 20. The air inlet of the vacuum generator 20 is fixedly connected to the gas supply pipe. The gas supply pipe is fixedly connected to the top of the cylinder 11 and connected to the guide groove 13. The vacuum generator 20 provides negative pressure to the guide groove 13 through the gas supply pipe to achieve adsorption and fixation of the reagent tube body 14 in the guide groove 13.

[0020] Two clamping mechanisms are provided on the base plate 7. Each clamping mechanism includes a telescopic cylinder 15 rotatably connected to the top of the base plate 7. A top block is fixedly connected to the top of the base plate 7. The telescopic cylinder 15 is rotatably connected to the top block and provides driving force to the clamping mechanism. The extension and retraction of its output end drives subsequent components in linkage. A first moving block 16 is rotatably connected to the output end of the telescopic cylinder 15. The first moving block 16 transmits the output force of the telescopic cylinder 15 to a second moving block 17, realizing the transmission and conversion of power. The first moving block 16 is fixedly connected to the second moving block 17. The second moving block 17 moves with the first moving block 16 and drives two clamping plates 18 to rotate around a second rotating axis. The first moving block 16 and the second moving block 17 are integrated and slidably connected to the top of the base plate 7. The second moving block 17 is rotatably connected to two clamping plates 18 (the clamping plates 18 can...). (The number of clamping plates 18 can be adjusted according to actual needs). The two clamping plates 18 rotate relative to each other under the drive of the second moving block 17, so as to clamp or release the reagent tube body 14. The side wall of the base plate 7 is fixedly connected to the connecting seat 19. Both clamping plates 18 are rotatably connected to the connecting seat 19. The connecting seat 19 provides a rotation fulcrum for the clamping plates 18 to ensure the stability of the rotation trajectory of the clamping plates 18. Both ends of the second moving block 17 are fixedly connected to the first rotating shaft. Both first rotating shafts pass through the clamping plates 18 and are rotatably connected to them. The clamping plates 18 are provided with a second rotating shaft that is rotatably connected to them. Both ends of the second rotating shaft are fixedly connected to the connecting seat 19. The first rotating shaft realizes the rotational connection between the second moving block 17 and the clamping plates 18, and the second rotating shaft realizes the rotational connection between the clamping plates 18 and the connecting seat 19, which together ensure the smooth operation of the clamping action.

[0021] In this utility model, the operator installs and fixes the robotic arm connector 1 to the robotic arm. The robotic arm can drive the equipment to move. When the robotic arm moves the equipment to the position of the reagent tube body 14 on the conveyor line, the power component 8 is activated, which pushes the base plate 7 down (the base plate 7, multiple cylinders 11 and placement cylinder 12 move down) until the reagent tube body 14 enters the guide groove 13. At this time, the vacuum generator 20 works to form a negative pressure in the guide groove 13, which picks up the reagent tube body 14. When it is moved to a certain height, the telescopic cylinder 15 is activated. The telescopic cylinder 15 drives the first moving block 16 and the second moving block 17 to move, which makes the clamping plate 18 rotate, thereby clamping and securing the reagent tube body 14. The transportation process can then be carried out, making the reagent tube body 14 stable during transportation and preventing it from falling off.
