[0034] This utility model proposes a rotation testing device 1000.

[0035] Please see Figures 1 to 6 In one embodiment of this utility model, the rotating testing device 1000 includes a workbench 1, a water storage mechanism 2, and a transmission mechanism 3. The workbench 1 has a first table surface 13, which is provided with multiple testing stations. A central column 11 is provided at the center of the workbench 1, and the central column 11 protrudes from the first table surface 13. The water storage mechanism 2 includes a water tank 21 and an annular water pipe 27. The water tank 21 is located above the workbench 1, and the annular water pipe 27 is connected to the water tank 21 and arranged around the circumference of the water tank 21. The annular water pipe 27 connects multiple testing stations around its circumference. The transmission mechanism 3 is located inside the workbench 1 and can drive the first table surface 13 and multiple water pipes to rotate around the central column 11 to quickly switch testing stations.

[0036] In this embodiment, the rotary testing device 1000 provided in this application can be applied not only to the testing of medical devices but also to the testing of automated equipment. Here, the testing of medical devices is used as an example. It should be noted that the medical devices mentioned here include, but are not limited to, infusion pumps, enteral nutrition pumps, and syringe pumps, and can provide infusion accuracy testing and other functional tests. It is understood that, in conjunction with... Figure 6The water storage mechanism 2 and the transmission mechanism 3 are connected by the central column 11 of the workbench 1. When the transmission mechanism 3 drives the first platform 13 and the annular water pipe 27 to rotate around the central column 11, the water pipe of the water storage mechanism 2 will move synchronously with the switching of the test station, ensuring that each test station can obtain a stable water supply during testing. The annular water pipe 27 is distributed around the circumference of the water storage tank 21. It should be noted that multiple control valves can be provided around the annular water pipe 27, and each control valve is connected to a test station. In one embodiment, the annular water pipe 27 is connected to the water storage tank 21 through multiple water pipes 22. Multiple control valves are provided around the annular water pipe 27 connected to the test station, and each control valve is connected to a test station. The test stations are set around the annular water pipe 27 and are set with corresponding control valves. Furthermore, in order to strengthen the connection strength of the annular water pipe 27, multiple reinforcing ribs connected to the water storage tank 21 are provided on the inner circumference of the annular water pipe 27. Specifically, the water storage tank 21 is connected to the test water source to provide a water supply. The connection between the water storage tank 21 and the external water source is achieved by a connecting pipe joint located at the bottom of the tank 21. This connecting pipe joint passes through the central column 11 and exits from the bottom of the central column 11, thus connecting to the external water source to enable automated water replenishment. The transmission mechanism 3 is located inside the workbench 1 and drives a gear or belt transmission structure via a motor or other power source to rotate the first platform 13 and the water pipe around the central column 11. Figure 1 and Figure 2 It should be noted that part of the structure of the water storage mechanism 2 passes through the central column 11. The test station (not shown in the figure) is distributed in a circle along the surface of the workbench 1 and is set at intervals on the rotatable structure of the workbench 1. Since the transmission mechanism 3 is connected to the first table surface 13, the first table surface 13 rotates around the central column 11, so that the test station rotates with the rotation of the first table surface 13.

[0037] The technical solution of this utility model sets up multiple test stations and a transmission mechanism 3. The transmission mechanism 3 is connected to the first platform 13, and the test stations are set on the first platform 13 of the workbench 1. The first platform 13 can rotate relative to the workbench 1 around the central column 11. Driven by the transmission mechanism 3, the device provided in this application can quickly switch test stations, reducing the time required for manual station changes or equipment adjustments in traditional devices, thereby significantly improving testing efficiency. At the same time, the design of the water storage mechanism 2 (water tank 21 and water pipes arranged circumferentially) ensures that each test station receives a stable water supply, avoiding differences in test conditions caused by uneven water supply, thereby improving the reliability of test results. The transmission mechanism 3 drives the first platform 13 to rotate, enabling rapid switching of test stations, thus completing the testing of multiple stations in a short time, greatly reducing the time spent switching stations during the testing process, and improving the overall testing efficiency. Meanwhile, workbench 1 is equipped with multiple testing stations, and each station corresponds to a water pipe, which can test multiple objects at the same time, further improving the batch processing capability of testing and meeting the needs of large-scale production or inspection.

[0038] In one embodiment of this utility model, the water storage mechanism 2 includes a spindle 23 and a synchronous gear 24 passing through the central column 11, the water storage tank 21 is located above the spindle 23, and the synchronous gear 24 is sleeved on the spindle 23; the transmission mechanism 3 includes a first drive unit 31 and a rotary gear 32 disposed on the worktable 1, the rotary gear 32 is sleeved on the outer periphery of the central column 11, and the synchronous gear 24 is sleeved on the outer side of the rotary gear 32, the first drive unit 31 is disposed on the worktable 1, and the output end of the first drive unit 31 is connected to the first table surface 13, the rotary gear 32, and the synchronous gear 24 respectively.

[0039] In this embodiment, in order to improve testing efficiency, combined with Figure 1 , Figure 2 as well as Figure 4 It can be seen that the mandrel 23 passes through the central column 11, and the two ends of the mandrel 23 are respectively connected to the water tank 21 and the synchronous gear 24, as shown. Figure 1 and Figure 2 As shown, the water tank 21 is positioned above the spindle 23, and the synchronous gear 24 is sleeved below the spindle 23. A water inlet pipe 25 is provided inside the spindle 23; one end of the water inlet pipe 25 is connected to the water tank 21, and the other end is connected to a test water source. The first drive unit 31 provides a power source to provide rotational power to the first platform 13. The type of the first drive unit 31 includes, but is not limited to, a servo motor and motor gear, a cylinder and gear (or chain), or a hydraulic motor and gear; no limitation is made here. Figure 4A rotary gear 32 is positioned above the workbench 1, and a first platform 13 is positioned above the rotary gear 32. The rotary gear 32 is sleeved on the outer periphery of the central column 11. This transmission connection allows the power of the first drive unit 31 to be transmitted to the water tank 21 and the first platform 13, thereby enabling multiple water pipes and multiple testing stations to rotate synchronously, improving the equipment's operating efficiency and stability. Furthermore, the presence of the rotary gear 32 allows the testing stations to rotate not only forward but also in reverse, increasing operational flexibility to meet the needs of different testing scenarios.

[0040] In one embodiment of the present invention, the first driving unit 31 includes a first driving member 311, a first gear 312 and a second gear 313. The output end of the first driving member 311 is respectively sleeved with the first gear 312 and the second gear 313. The first gear 312 is connected to the rotating shaft of the first platform 13 for transmission. The second gear 313 is meshed with the synchronous gear 24. The first gear 312 is meshed with the rotary gear 32.

[0041] In this embodiment, to further improve the accuracy of each test station stopping in front of the tester, a servo motor and motor gears are preferably used to achieve synchronous rotation of multiple water pipes and multiple test stations. The first drive component 311 is a servo motor, and the first gear 312, second gear 313, and synchronization gear 24 are preferably spur gears. Figure 5 The first driving component 311 has a motor mounting base, which is connected to the internal cavity wall of the worktable 1 via bolts, snap-fit, or other means. The first gear 312 and the second gear 313 are both mounted on the output drive shaft of the first driving component 311. The first gear 312 is positioned above the motor mounting base, and the second gear 313 is positioned below it. Specifically, the first gear 312 can be connected to the first table surface 13 via a solid or hollow shaft; this is not limited here. The second gear 313 meshes with the synchronous gear 24, and the first gear 312 meshes with the rotary gear 32. By changing the rotation direction of the first driving component 311, the first gear 312 and the second gear 313 can rotate in opposite directions, thereby driving the first table surface 13 and the rotary gear 32 to rotate in opposite directions. It should be noted that the control method of the first driving component 311 can be precisely controlled by a controller (such as a PLC, microcontroller, etc.), including speed, direction, and start / stop. Furthermore, combined with... Figure 5A planetary reducer 314 is also fitted onto the drive shaft at the output end of the first drive component 311. The planetary reducer 314 is positioned below the second gear 313. The presence of the planetary reducer 314 enhances the driving capability of the first drive component 311, enabling it to drive the first gear 312 and the second gear 313 more effectively. Through the cooperation of the first drive component 311, the first gear 312, and the second gear 313, power can be transmitted efficiently, energy loss reduced, and the power transmission efficiency of the equipment improved.

[0042] In one embodiment of this utility model, the transmission mechanism 3 further includes a sliding contact structure 33 and a rotary gear 32, and the rotation testing device 1000 further includes a power socket 4. The sliding contact structure 33 includes a sliding contact ring 331, a second driving member 332, and a driving arm 333. The sliding contact ring 331 is disposed inside the workbench 1. One end of the driving arm 333 is connected to the second driving member 332 in a transmission manner, and the other end of the driving arm 333 is fixed to the central column 11. The second driving member 332 is provided with a conductive sheet, which is in movable contact with the sliding contact ring 331. The sliding contact ring 331 is provided with a ribbon cable, which is electrically connected to the power socket 4.

[0043] In this embodiment, to ensure the device receives continuous power while rotating and to avoid cable tangling or power outages caused by rotation, this application incorporates a sliding contact mechanism to achieve dynamic power supply. Combined with... Figure 3 and Figure 4 The sliding contact structure 33 includes a sliding contact wire ring 331 disposed outside the rotary gear 32. It can be understood that the sliding contact wire ring 331 consists of a wire ring support 331a and a wire ring body 331b. The wire ring support 331a is arranged in a ring shape along the center of the central column 11 and is erected above the workbench 1 (above the first table surface 13). The wire ring body 331b is connected to the inner wall of the wire ring support 331a by bolts, screws, or other means. The other end of the second driving member 332 that abuts against the sliding contact wire ring 331 is provided with a driving arm 333, which is disposed on the outer side of the central column 11. The power socket 4 is disposed on the outer wall of the wire ring support 331a and is movably abutted against the sliding contact wire ring 331 by the second driving member 332, thereby maintaining a good electrical connection. Understandably, the outer wall of the wire ring support 331a is also equipped with a manual control button and a power switch, so that in an emergency, the operator can quickly operate the manual control button to cut off or restore power in a timely manner, reducing the risk of equipment damage or accidents. When the second drive component 332 rotates to a certain position of the sliding contact wire ring 331, the circuit of the power socket 4 corresponding to that position is turned on to realize the power supply for connecting external structures, including but not limited to test equipment such as syringe pumps and infusion pumps. Figure 3Since the power sockets 4 are spaced along the outer wall of the line ring support 331a, multiple power sockets 4 are set up corresponding to each test station in order to provide power sockets 4 for each test station. At the same time, the drive arm 333 is connected to the rotary gear 32 for transmission. When the rotary gear 32 rotates under the drive of the first gear 312, that is, when the first table 13 rotates under the rotation of the first drive part 31, the drive arm 333 also rotates synchronously, so that the equipment can continuously obtain power when rotating. It can be understood that the workbench 1 is equipped with a power supply, which is electrically connected to the wire in the drive arm 333 through a conductive wire, so that the second drive member 332 rotates to a certain position of the sliding contact line ring 331, and the circuit of the power socket 4 corresponding to that position is turned on to realize the power supply to the external structure. It should be noted that the second drive member 332 includes one or more conductive plates (or brushes, brush blocks). The number of these conductive sheets is typically matched to the number of rings on the sliding contact ring 331. In this embodiment, the sliding contact ring 331 has three rings, with an insulating layer between each ring. The number of rings on the sliding contact ring is not limited here and may include two, three, etc. The conductive sheets are typically made of materials with good conductivity and wear resistance, such as copper alloys, silver alloys, or graphite-containing composite materials.

[0044] In one embodiment of this utility model, the sliding contact wire ring 331 includes a wire ring support 331a and a wire ring body 331b disposed on the workbench 1. The wire ring body 331b is disposed on the wire ring support 331a, and the wire ring support 331a is arranged in a ring shape along the central column 11. The rotation test device 1000 also includes a plurality of power supply sockets 4, each power supply socket 4 being distributed at intervals along the outer peripheral wall of the wire ring support 331a and corresponding to a test station.

[0045] In this embodiment, combined with Figure 1 Power socket 4 is used to power the equipment at the test station. It should be noted that power socket 4 is preferably a three-position socket, ensuring the test equipment receives 220V AC power during rotation. Test personnel can quickly connect the equipment to the corresponding power socket 4, reducing test preparation time and improving test efficiency. Multiple power sockets 4 allow simultaneous power supply to multiple test devices, enabling simultaneous testing at multiple test stations and improving overall test efficiency.

[0046] In one embodiment of this utility model, the workbench 1 includes a frame 12 and a second table surface 14. The first table surface 13 is disposed on the frame 12. The central column 11 passes through the frame 12, the first table surface 13 and the second table surface 14 in sequence. The second table surface 14 is disposed above the first table surface 13. The transmission mechanism 3 includes a first driving part 31 and a sliding contact structure 33. The second table surface 14 covers the sliding contact structure 33. The first driving part 31 and part of the water storage mechanism 2 are disposed inside the frame 12.

[0047] In this embodiment, combined with Figure 1 and Figure 2 It should be noted that the second platform 14 covers the sliding contact structure 33 to prevent external environmental factors such as dust, water droplets, and debris from interfering with the sliding contact structure 33, thereby improving the reliability and service life of the sliding contact structure 33. Here, the second platform 14 is a fixed platform and does not rotate with the rotation of the first platform 13. The portion of the second platform 14 that covers the first platform 13, together with the wire ring support 331a in the sliding contact structure 33, forms a limiting space for the second drive component 332, the synchronous gear 24, and the rotary gear 32, further protecting the overall equipment.

[0048] In one embodiment of the present invention, the water storage mechanism 2 further includes a central water pipe passing through the central column 11, a water inlet connector connected to the test water source, and a rotary connector 26. The water inlet connector is located inside the workbench 1, and the two ends of the rotary connector 26 are respectively connected to the central water pipe and the water inlet connector.

[0049] In this embodiment, combined with Figure 1 and Figure 2 A central water pipe passes through a mandrel 23 and then through a central column 11. The two ends of the central water pipe are connected to a water storage tank 21 and a rotary joint 26, respectively. The rotary joint 26 connects the central water pipe to the inlet connector, allowing water to enter the rotary joint 26 through the inlet connector and then be transported to the water storage tank 21 via the central water pipe. The rotary joint 26 ensures smooth water flow when the central column 11 rotates. Furthermore, to prevent over-rotation, a locking plate is provided on the rotary joint 26 to limit its rotation angle and prevent damage to internal seals or connecting components due to excessive rotation.

[0050] In one embodiment of this utility model, the water storage mechanism 2 further includes a float valve, which is located inside the water storage tank 21.

[0051] In this embodiment, it should be noted that the float valve is not shown. The float valve is used to automatically control the water level in the water storage tank 21. When the water level drops to the set minimum level, the float valve will automatically open, allowing water to flow into the water storage tank 21 for replenishment; when the water level rises to the set maximum level, the float valve will automatically close, stopping water replenishment. The automatic water level control function reduces the need for frequent manual checks and manual water replenishment, reducing labor costs and the risk of operational errors.

[0052] In one embodiment of this utility model, each water pipe is distributed circumferentially along the water storage tank 21, and a connecting pipe is provided between the test station and each water pipe, with a control valve inside the connecting pipe.

[0053] In this embodiment, combined with Figure 1 and Figure 2The water pipes are evenly distributed along the circumference of the water tank 21 to ensure uniform water supply to each test station, avoiding test errors caused by uneven water supply. Each test station is connected to the water pipes by a connecting pipe and a control valve, allowing independent control of the water supply to each station, improving the flexibility and accuracy of the test; it also reduces water flow interference between different test stations. It is understood that the control valve here includes, but is not limited to, solenoid valves, manual valves, proportional valves, etc., and is not limited here; it can be set according to specific needs.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
