Description

Technical Field

[0001] This utility model relates to the field of luminescence measuring instruments, and in particular to the magnetic rod sleeve mounting structure of luminescence measuring instruments. Background Technology

[0002] Chemiluminescence assay technology is a novel technology that combines highly sensitive chemiluminescence assay technology with highly specific immunoassay technology. It is mainly used for the detection and analysis of solution concentrations of various antigens, haptens, antibodies, hormones, enzymes, fatty acids, vitamins, and drugs.

[0003] In existing chemiluminescence analyzers, test tubes containing the detection solution are typically placed inside the instrument, and then stirred by a magnetic stirrer. Before stirring, a sleeve needs to be fitted onto the magnetic rod on the stirring plate. This is to prevent the magnetic rod from contaminating the solution and also to prevent the solution from corroding the magnetic rod, thus reducing its lifespan. Currently, operators usually manually install the sleeve onto the stirring plate. After testing, the sleeve needs to be removed and replaced with a new one, requiring manual operation for each test, causing inconvenience to users and resulting in low stirring efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an efficient magnetic rod sleeve installation structure for a luminescence measuring instrument that enables automatic installation of a magnetic rod sleeve onto a magnetic rod.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a magnetic rod sleeve mounting structure for a luminescence measuring instrument, including a luminescence measuring instrument body, a stirring plate inside the luminescence measuring instrument body, and magnetic rods evenly arranged around the rotation axis of the stirring plate on the bottom surface of the stirring plate. It includes a magnetic rod sleeve replacement mechanism, comprising a first connecting ring, an electric telescopic rod fixedly connected to the top of the first connecting ring, a second connecting ring fixedly connected to the top of the electric telescopic rod, a second mounting ring rotatably connected to the top of the second connecting ring, and a second transmission mechanism between the second mounting ring and the second connecting ring. The second transmission mechanism is used to drive the second mounting ring to rotate. A transmission groove is opened on the top of the second mounting ring, and an electromagnet plate is fixedly connected in the transmission groove. It also includes a third mounting ring, on which a transmission iron block is arranged. The transmission iron block is electromagnetically attracted to the electromagnet plate. A magnetic rod sleeve is fixedly connected to the bottom of the third mounting ring, and the magnetic rod sleeve is correspondingly arranged with the magnetic rods. A threaded sleeve is provided on the top of the third mounting ring, and a threaded groove matching the threaded sleeve is opened on the bottom of the stirring plate.

[0006] Furthermore, it includes a mounting column, which is disposed within the main body of the luminescence measuring instrument; a first mounting ring, which is rotatably connected to the mounting column, and a first connecting ring, which is fixedly connected to the first mounting ring; and a first transmission mechanism, which is disposed between the mounting column and the first mounting ring, and is used to drive the first mounting ring to rotate around the mounting column.

[0007] Furthermore, the first transmission mechanism includes a first motor fixedly connected to the mounting column, the output end of the first motor being fixedly connected to a first rotating shaft via a coupling, a first gear being fixedly sleeved on the outer surface of the first rotating shaft, and a second gear being fixedly sleeved on the outer surface of the first gear and meshing with the first mounting ring.

[0008] Furthermore, the second transmission mechanism includes a second motor fixedly connected to the second connecting ring, the output end of the second motor being fixedly connected to a second rotating shaft via a coupling, a third gear being fixedly sleeved on the outer surface of the second rotating shaft, and a fourth gear being fixedly sleeved on the outer surface of the third gear.

[0009] Furthermore, it includes a cleaning and drying mechanism for sequentially cleaning and drying the magnetic rod sleeve, the cleaning and drying mechanism comprising a cleaning tank and a drying tank.

[0010] Furthermore, the cleaning and drying mechanism includes a transmission disc slidably connected to the mounting column. A cleaning tank is fixedly connected to one side of the transmission disc via a first connecting plate. A cleaning coil tube is fixedly connected inside the cleaning tank, and a cleaning pipe is fixedly connected inside the cleaning tank. The cleaning pipe is connected via a first coil tube. Cleaning nozzles are fixedly installed on the outer surfaces of both the cleaning coil tube and the cleaning pipe. A water pump is fixedly connected to the connecting plate. The output end of the water pump is fixedly connected to a first connecting pipe that is fixedly connected to both the cleaning coil tube and the first coil tube. A drain pipe is fixedly connected to the bottom of the cleaning tank. A third transmission mechanism connected to the mounting column is driven to the transmission disc, and the third transmission mechanism is used to drive the transmission disc to move.

[0011] Furthermore, a drying drum is fixedly connected to the outer surface of the transmission disc via a second connecting plate. A drying coil tube is fixedly connected inside the drying drum, and a drying pipe is fixedly connected inside the drying drum. The drying pipe is connected via a second coil tube. A drying cover is fixedly connected to the outer surface of both the drying coil tube and the drying pipe. A hot air blower is fixedly connected to the connecting plate, and a second connecting pipe is provided at the output end of the hot air blower, which is fixedly connected to both the drying coil tube and the second coil tube.

[0012] Furthermore, the third transmission mechanism includes a third motor fixedly connected to the mounting column, and the output end of the third motor is fixedly connected to a threaded rod that is threadedly connected to the transmission disk via a coupling. A guide rod that is fixedly connected to the mounting column is slidably connected to the transmission disk.

[0013] The beneficial effects of this utility model are as follows: First, when it is necessary to install the magnetic rod sleeve onto the magnetic rod, the first connecting ring is first positioned below the magnetic rod. Then, the electric telescopic rod is raised to bring the third mounting ring close to the mixing plate, and the threaded sleeve of the third mounting ring is tightly fitted with the threaded groove at the bottom of the mixing plate. Subsequently, the second mounting ring is rotated by the second transmission mechanism. Since the second and third mounting rings are connected by an electromagnet plate and a transmission iron block that are magnetically attracted to each other, the third mounting ring will also rotate, allowing the threaded sleeve of the third mounting ring to screw into the threaded groove at the bottom of the mixing plate, thus achieving the effect of installing the magnetic rod sleeve onto the magnetic rod. Afterwards, simply de-energizing the electromagnet plate will separate the second and third mounting rings. The installed third mounting ring and the magnetic rod sleeve are fixedly positioned at the bottom of the mixing plate, and the magnetic rod sleeve is securely fitted onto the magnetic rod. Second, when it is necessary to remove the used magnetic rod sleeve, the operation is reversed from the installation steps. The second transmission mechanism drives the second mounting ring to rotate in the opposite direction, coordinating with the downward retraction of the electric telescopic rod and the connection and disconnection between the electromagnet plate and the transmission block. This allows the threaded sleeve of the third mounting ring to unscrew from the threaded groove at the bottom of the stirring plate. Third, the removed magnetic rod sleeve is sequentially cleaned and dried by the cleaning and drying mechanism and then reused, realizing the recycling of the magnetic rod sleeve. This invention is particularly suitable for the automatic installation and disassembly of magnetic rod sleeves in luminescence measuring instruments. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 6 The luminescence measuring instrument shown includes a main body 1, within which a vertically movable stirring plate 2 is disposed. Multiple magnetic rods 3 are fixedly connected to the bottom of the stirring plate 2, and the magnetic rods 3 are evenly arranged around the bottom circumference of the stirring plate 2. A mounting column 4 is fixedly connected inside the main body 1, and a magnetic rod sleeve replacement mechanism is provided on the mounting column 4 for automatically replacing the magnetic rod sleeves on the stirring plate 2. A cleaning and drying mechanism is provided on the mounting column 4 for automatically cleaning and drying the magnetic rod sleeves. A fixing plate is fixedly connected to the bottom of the mounting column 4, and the mounting column 4 is fixedly disposed inside the main body 1 via the fixing plate.

[0022] By placing the magnetic rod sleeve into the magnetic rod sleeve replacement mechanism, the mechanism automatically feeds the magnetic rod sleeve to the bottom of the stirring plate 2 on the main body 1 of the luminescence analyzer, and simultaneously automatically installs the magnetic rod sleeve onto the magnetic rod 3 at the bottom of the stirring plate 2, thus achieving automatic and portable installation of the magnetic rod sleeve. After the magnetic rod stirs the substance in the test tube, the magnetic rod sleeve replacement mechanism automatically unloads the magnetic rod sleeve 3 from the stirring plate 2, and then automatically feeds a clean magnetic rod sleeve back onto the magnetic rod 3 at the bottom of the stirring plate 2, thus achieving portable and automatic replacement of the magnetic rod sleeve. The replaced magnetic rod sleeve is sent to the cleaning and drying mechanism, where the outer surface of the magnetic rod sleeve is thoroughly cleaned and dried for future replacement, thus achieving reuse of the magnetic rod sleeve.

[0023] The magnetic rod sleeve replacement mechanism includes a first mounting ring 11 rotatably connected to the mounting post 4. A first transmission mechanism, connected to the mounting post 4, is driven to rotate the first mounting ring 11 via a transmission plate on the outer surface of the first mounting ring 11. Two first connecting rings 12 are fixedly connected to the outer surface of the first mounting ring 11 via a connecting plate, with the two first connecting rings 12 respectively located on the left and right sides of the first mounting ring 11. An electric telescopic rod 13 is fixedly connected to the top of the first connecting ring 12, with the telescopic direction of the electric telescopic rod 13 perpendicular to the first connecting ring 12. A second connecting ring 14 is fixedly connected to the top of the electric telescopic rod 13, and a second mounting ring 15 is rotatably connected to the top of the second connecting ring 14. A second transmission mechanism, connected to the second connecting ring 14, is driven to rotate the second mounting ring 15 via a transmission plate on the outer surface of the second mounting ring 15.

[0024] The top of the second mounting ring 15 has a transmission groove 16, and an electromagnet plate 17 is fixedly connected inside the transmission groove 16. The electromagnet plate 17 and the transmission iron block 18 are attracted by electromagnetic force. The transmission iron block 18 is fixedly connected to the third mounting ring 19, and multiple magnetic rod sleeves 190 are fixedly connected to the bottom of the third mounting ring 19. The magnetic rod sleeves 190 are set perpendicular to the third mounting ring 19. The top of the third mounting ring 19 is fixedly connected to a threaded sleeve 191, and the bottom of the stirring plate 2 has a threaded groove 192.

[0025] The first transmission mechanism includes a first motor 21 fixedly connected to the mounting column 4. The first motor 21 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the first motor 21. The output end of the first motor 21 is fixedly connected to a first rotating shaft 22 via a coupling. A first gear 23 is fixedly sleeved on the outer surface of the first rotating shaft 22. A second gear 24, which is fixedly sleeved on the outer surface of the first gear 23, is meshed with the outer surface of the first gear 23. The first motor 21 drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the first mounting ring 11 to rotate via the first gear 23 and the second gear 24.

[0026] The second transmission mechanism includes a second motor 31 fixedly connected to the second connecting ring 14. The second motor 31 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the second motor 31. The output end of the second motor 31 is fixedly connected to a second rotating shaft 32 via a coupling. A third gear 33 is fixedly sleeved on the outer surface of the second rotating shaft 32. A fourth gear 34, which is fixedly sleeved on the outer surface of the third gear 33, is meshed with the third mounting ring 19. The second motor 31 drives the second rotating shaft 32 to rotate, and the second rotating shaft 32 drives the third mounting ring 19 to rotate via the third gear 33 and the fourth gear 34.

[0027] By placing the third mounting ring 19, which is equipped with multiple magnetic rod sleeves 190, into the second mounting ring 15, and simultaneously aligning the transmission iron block 18 at the bottom of the third mounting ring 19 with the transmission groove 16 at the top of the second mounting ring 15, the electromagnet plate 17 in the transmission groove 16 is energized, thereby attracting the transmission iron block 18 and fixing the third mounting ring 19. Subsequently, the first transmission mechanism drives the first mounting ring 11 to rotate, which in turn drives the first connecting ring 12 to rotate. The first connecting ring 12 then drives the electric telescopic rod 13 and the second connecting ring 14 to rotate, which in turn drives the second mounting ring 15 to rotate. The second mounting ring 15 then drives the third mounting ring 19 to rotate below the magnetic rod 3. Subsequently, the electric telescopic rod 13 drives the second connecting ring 14 and the second mounting ring 15 to move upwards, and the second mounting ring 15 drives the third mounting ring 19 to move upwards, causing the threaded sleeve 191 on the third mounting ring 19 to insert into the threaded groove 192 at the bottom of the mixing plate 2. Next, the second transmission mechanism drives the third mounting ring 19 to rotate, which in turn drives the threaded sleeve 191 to rotate. Simultaneously, the electric telescopic rod 13 moves the second connecting ring 14 and the third mounting ring 19 upward, so that the threaded sleeve 191 on the third mounting ring 19 is screwed into the threaded groove 192 for fixation, thus securing the third mounting ring 19 to the mixing plate 2. Subsequently, the electromagnet plate 17 in the transmission groove 16 is de-energized and no longer attracts the transmission iron block 18. The electric telescopic rod 13 drives the second connecting ring 14 downward, which in turn drives the second mounting ring 15 downward, causing the second mounting ring 15 to detach from the magnetic rod sleeve 190. Then, the first transmission mechanism drives the first mounting ring 11 to rotate 90° to avoid the mixing plate 2, after which the mixing plate 2 begins operation.

[0028] After the mixing plate 2 finishes its work, the first transmission mechanism drives the first mounting ring 11 to rotate -90°. Then, the electric telescopic rod 13 drives the second connecting ring 14 upwards, causing the transmission block 18 to enter the transmission groove 16 within the second mounting ring 15 for fixation. The second mounting ring 15 then rotates, causing the third mounting ring 19 to rotate, thus unscrewing the threaded sleeve 191 from the threaded groove 192 on the third mounting ring 19. Next, the electric telescopic rod 13 drives the second connecting ring 14 downwards, and the first transmission mechanism drives the first mounting ring 11 to rotate 180°. The new magnetic rod sleeve 190 is then installed on the mixing plate 2 using the same steps, followed by a 90° rotation. The removed magnetic rod sleeve 190 is then rotated to the cleaning and drying mechanism for cleaning and drying, thus enabling portable and automatic replacement of the magnetic rod sleeve 190, facilitating user operation.

[0029] The cleaning and drying mechanism includes a transmission disc 41 slidably connected to a mounting column 4. A cleaning tank 42 is fixedly connected to one side of the transmission disc 41 via a connecting plate and a connecting column. Two cleaning coils 43 are fixedly connected inside the cleaning tank 42, and multiple cleaning pipes 44 are also fixedly connected inside the cleaning tank 42. The multiple cleaning pipes 44 are connected by a first coil 45. Cleaning nozzles 46 are fixedly connected to the outer surfaces of both the cleaning coils 43 and the cleaning pipes 44. A water pump 47 is fixedly connected to the connecting plate, and the output end of the water pump 47 is fixedly connected to a first connecting pipe 48, which is fixedly connected to both the cleaning coils 43 and the first coil 45. A drain pipe is fixedly connected to the bottom of the cleaning tank 42. A third transmission mechanism connected to the mounting column 4 is driven to move the transmission disc 41.

[0030] The third transmission mechanism includes a third motor 61 fixedly connected to the mounting column 4. The third motor 61 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the third motor 61. The output end of the third motor 61 is fixedly connected to a threaded rod 62 that is threadedly connected to the transmission disk 41 via a coupling. A guide rod 63, which is fixedly connected to the mounting column 4, is slidably connected to the transmission disk 41. The third motor 61 drives the threaded rod 62 to rotate, and the threaded rod 62 drives the transmission disk 41 to move up and down.

[0031] A drying drum 51 is fixedly connected to the outer surface of the transmission disc 41 via a connecting plate and a connecting column. Two drying coils 52 are fixedly connected inside the drying drum 51, and multiple drying tubes 53 are fixedly connected inside the drying drum 51. The multiple drying tubes 53 are connected by a second coil 54. A drying cover 55 is fixedly connected to the outer surface of both the drying coils 52 and the drying tubes 53. A hot air blower 56 is fixedly connected to the connecting plate, and a second connecting tube 57 is fixedly connected to the output end of the hot air blower 56, which is also fixedly connected to both the drying coils 52 and the second coil 54.

[0032] After the magnetic rod sleeve is replaced, it rotates 90°, meaning the first transmission mechanism drives the first mounting ring 11 to rotate 90° to move the removed magnetic rod sleeve 190 above the cleaning tank 42. Then, the third transmission mechanism drives the threaded rod 62 to rotate, which in turn drives the transmission disc 41 to move upwards. The transmission disc 41, through the connecting plate, drives the cleaning tank 42 to move upwards, allowing the magnetic rod sleeve 190 to enter the cleaning tank 42. Subsequently, the water pump 47 pumps cleaning fluid through the first connecting pipe 48 into the first ring pipe 45 and the cleaning ring pipe 43. The first ring pipe 45 then passes the cleaning fluid into the cleaning pipe 44, and the cleaning pipe 44 and the cleaning ring pipe 43 spray the cleaning fluid through the cleaning nozzle 46 to clean the surface of the magnetic rod sleeve 190. Simultaneously, the third mounting ring 19 is rotated by the second transmission mechanism, which in turn rotates the magnetic rod sleeve 190. The magnetic rod sleeve 190 rotates within the cleaning tank 42, allowing the cleaning nozzle 46 to spray water onto the magnetic rod sleeve 190 from multiple angles, achieving thorough cleaning. After cleaning, when the third mounting ring 19 on the mixing plate 2 is replaced, the cleaned magnetic rod sleeve 190 rotates to the top of the drying tank 51. Then, the third transmission mechanism moves the transmission plate 41 and the drying tank 51 upwards, allowing the cleaned magnetic rod sleeve 190 to enter the drying tank 51. The hot air blower 56 then operates, supplying hot air to the second coil tube 54 and the drying coil tube 52 through the second connecting pipe 57. The hot air is blown out through the drying hood 55 on the drying coil tube 52 and the drying pipe 53, while the second transmission mechanism rotates the third mounting ring 19. At this time, the drying hood 55 at multiple angles dries the cleaned magnetic rod sleeve 190 with hot air, thereby realizing the automatic cleaning and drying of the used magnetic rod sleeve 190 for reuse and achieving the reuse of the magnetic rod sleeve 190.

[0033] The working principle of this invention is as follows: The magnetic rod sleeve is placed into the magnetic rod sleeve replacement mechanism, which then automatically feeds the magnetic rod sleeve onto the bottom of the stirring plate 2 on the main body 1 of the luminescence analyzer. The magnetic rod sleeve is then automatically installed onto the magnetic rod 3 at the bottom of the stirring plate 2, thus achieving automatic and portable installation of the magnetic rod sleeve. After the magnetic rod stirs the substance in the test tube, the magnetic rod sleeve replacement mechanism automatically unloads the magnetic rod sleeve 3 from the stirring plate 2, and then automatically feeds a clean magnetic rod sleeve back onto the bottom of the stirring plate 2 for secure installation, thus achieving portable and automatic replacement of the magnetic rod sleeve. The replaced magnetic rod sleeve is then sent to a cleaning and drying mechanism, which thoroughly cleans the outer surface of the magnetic rod sleeve and then dries it for easy replacement next time, thus achieving reuse of the magnetic rod sleeve.
