[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings of the embodiments. This utility model is not limited to the following specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.
[0023] like Figures 1 to 5 As shown, an automatic electrode replacement device for an oil spectrometer 600 includes: a fixing plate 100, a material feeding mechanism 200, a first driving mechanism 300, a second driving mechanism 400, and a waste collection box 500; the fixing plate 100 is used to connect to the external oil spectrometer 600, the material feeding mechanism 200, the first driving mechanism 300, and the second driving mechanism 400 are arranged sequentially from top to bottom on the fixing plate 100, and the waste collection box 500 is located below the second driving mechanism 400.
[0024] Specifically, the material feeding mechanism 200 includes a fixed base 210, a first drive motor 220, a first pusher block 230, and two feed pipes 240. The fixed base 210 is disposed on one side of the fixed plate 100. The first drive motor 220 and the two feed pipes 240 are all disposed on the fixed base 210. The output shaft of the first drive motor 220 is movably connected to the first pusher block 230 through a limiting block 250. A sliding track 211 is provided on the fixed base 210, and the first pusher block 230 slides on the sliding track 211. The limiting block 250 has a limiting groove 251, and a limiting block 231 protrudes from the first pusher block 230, with the limiting block 231 located within the limiting groove 251.
[0025] In one embodiment, the first drive mechanism 300 includes a second drive motor 310, a first gearbox 320, a first mounting shaft 330, a mounting block 340, a first placement plate, a second placement plate, a third placement plate, and two insert blocks 380. The first drive motor 320 is mounted on the fixed plate 100. The output shaft of the second drive motor 310 is connected to the first gearbox 320. One end of the first mounting shaft 330 is connected to the first gearbox 320, and the other end is rotatably mounted on the fixed plate 100. The mounting block 340 is mounted on the first mounting shaft 330. The first placement plate, the second placement plate, and the third placement plate are sequentially mounted on the mounting block 340 from top to bottom. One insert block 380 is located below the fixed base 210, and the other insert block 380 is located on the fixed plate 100. One insert block 380 is movably inserted into the middle of the first placement plate, and the other insert block 380 is movably inserted into the middle of the third placement plate. Further, the first placement plate includes a first spring 351, two first half-plates 352, and four stops 353. The two first half-plates 352 are rotatably mounted on the mounting block 340 and are in contact with each other. One end of the first spring 351 is connected to one first half-plate 352, and the other end is connected to the other first half-plate 352. Two stops 353 are provided on each first half-plate 352. The second placement plate includes two second half-plates 360, which are rotatably mounted on the mounting block 340 and are in contact with each other. The third placement plate includes a second spring 371 and two third half-plates 372, which are rotatably mounted on the mounting block 340 and are in contact with each other. One end of the second spring 371 is connected to one third half-plate 372, and the other end is connected to the other third half-plate 372. It is worth mentioning that after the two second half plates 360 abut together, they form two first placement openings, and after the two third half plates 372 abut together, they form two second placement openings. The diameter of each second placement opening is smaller than the diameter of a first placement opening.
[0026] In one embodiment, the second drive mechanism 400 includes a third drive motor 410, a second gearbox 420, a second mounting shaft 430, a second pusher block 440, and a mounting base 450. The third drive motor 410 is mounted on the fixed plate 100, and the output shaft of the third drive motor 410 is connected to the second gearbox 420. One end of the second mounting shaft 430 is connected to the second gearbox 420, and the other end is connected to the second pusher block 440 through a connecting block. The second pusher block 440 is rotatably mounted on the mounting base 450.
[0027] In other words, the entire replacement device needs to be used with an external oil spectrometer 600. During use, the mounting plate 100 is installed on the external oil spectrometer 600, and all wires are electrically connected. It is then used directly with the control system 700 of the oil spectrometer 600. That is, the entire replacement device can be controlled by the PLC control system 700 of the external oil spectrometer 600. Furthermore, both feed pipes 240 are used to place the disc electrodes.
[0028] In use, the control system 700 controls the output shaft of the first drive motor 220 to rotate, causing the limiting block 231 to rotate. The rotation of the limiting block 231 pushes the first pusher block 230 to slide within the sliding track 211. In other words, the rotation of the output shaft of the first drive motor 220 drives the limiting block 231 to rotate, thereby causing the limiting block 231 to perform a circular motion with the output shaft of the first drive motor 220 as the center. Since the limiting block 231 has a limiting groove 251, and the first pusher block 230 has a protruding limiting block 231 located within the limiting groove 251, the rotation of the limiting block 250 causes the limiting block 231 to move within the limiting groove 251, thereby causing the first pusher block 230 to slide within the sliding track 211. That is, the lowermost disc electrodes in the two feed pipes 240 are located on one side of the sliding track 211, and then the first pusher block 230 pushes the two lowermost disc electrodes off the fixed base 210. It is worth mentioning that, in the initial state, the insert block 380 located below the fixing base 210 opens the two first half-plates 352, allowing the two disk electrodes to fall smoothly into the two first placement openings. Since the diameter of each second placement opening is smaller than the diameter of the first placement opening, and the diameter of the disk electrode is larger than the diameter of the second placement opening, the disk electrodes falling into the first placement openings will not fall out. Then, the second drive motor 310 is started, and the output shaft of the second drive motor 310 rotates, driving the first mounting shaft 330 to rotate, which in turn causes the mounting block 340 to rotate downwards. At this time, the insert block 380 no longer opens the two first half-plates 352, and under the action of the first spring 351, the two first half-plates 352 return to their initial positions. That is, the four stops 353 located on the two first half-plates 352 block one disk electrode with every two stops 353, thus preventing the disk electrodes from falling out when rotating downwards. It is also worth mentioning that the fixing plate 100 is provided with two connecting shafts, each driven by an external drive source. In other words, after the two disk electrodes located in the two first placement ports rotate down, each disk electrode will be inserted into a connecting shaft. Since the insert block 380 on the fixed plate 100 will open the two third half-plates 372, it will not affect the insertion of the two disk electrodes into the two connecting shafts. At this time, the mounting block 340 continues to rotate downwards. Therefore, the four stops 353 push the two disk electrodes to fix them in place on the two connecting shafts. Since the insertion of each disk electrode into a connecting shaft is an interference fit, the two disk electrodes can be driven to rotate by an external drive source. That is, after insertion, the output shaft of the second drive motor 310 reverses, driving the mounting block 340 to rotate upwards. At this time, the insert block 380 on the fixed plate 100 gradually stops opening the two third half-plates 372. That is, after passing the two disk electrodes, the two third half-plates 372 return to their initial position under the action of the second spring 371, thus reforming the two second placement ports.Finally, the entire mounting block 340, along with the first, second, and third placement plates, will be returned to its initial position. Then, the sample cup will be placed below the two disk electrodes. The two connecting shafts will be driven to rotate by an external drive source, thereby rotating the two disk electrodes. The entire experiment can then be completed in conjunction with the excitation and detection system of the oil spectrometer 600.
[0029] After the experiment is completed, the two disk electrodes need to be replaced. By starting the third drive motor 410, the output shaft of the third drive motor 410 rotates, which drives the second mounting shaft 430 to rotate, which in turn causes the connecting block to rotate, which in turn drives the second pusher block 440 to rotate. Therefore, the two disk electrodes located on the two connecting shafts can be pushed out directly and fall into the waste collection box 500 located below them, thus completing a detection process.
[0030] In summary, the above embodiments are not limiting embodiments of this utility model. Any modifications or equivalent variations made by those skilled in the art based on the substantive content of this utility model are within the technical scope of this utility model.
