DETAILED DESCRIPTION OF THE INVENTION

[0020] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] Please refer to Figures 1 to 4 , an inductively coupled plasma mass spectrometry determination device is provided in an embodiment of the present application, including a frame 1, on which a pressure cylinder 2 is installed. The pressure cylinder 2 can be a hydraulic cylinder or a pneumatic cylinder. The two output ends of the pressure cylinder 2 are slidably and hermetically connected to an arc-shaped plate 3. The arc-shaped plate 3 and the pressure cylinder 2 form a loading ring. The input end of the pressure cylinder 2 is slidably and hermetically connected to a sealing plate 4. A linear actuator 5 is installed on the frame 1. The linear actuator 5 can be an electric cylinder. The output end of the linear actuator 5 is connected to the sealing plate 4. A rotary driving device 6 is rotatably connected to the frame 1. The rotary driving device 6 can be a servo motor. The output end of the rotary driving device 6 is provided with a turntable 7. A number of receiving brackets 8 are installed on the turntable 7. Two rotary driving devices 9 are installed on the receiving brackets 8. The rotary driving device 9 can be a servo motor. Two symmetrically arranged clamping plates 10 are installed on the receiving brackets 8. The output end of the rotary driving device 9 is in transmission connection with the clamping plate 10. The clamping plate 10 and the receiving bracket 8 form a material-changing ring. An extrusion mechanism for extruding a dropper is installed on the frame 1, and a blanking mechanism for replacing the dropper is installed on the frame 1. The turntable 7 can be rotated forward by a certain number of turns and then reversed, so as to avoid the power cord connecting the rotary driving device 9 from being wound and knotted. The rotary driving device 6, the rotary driving device 9, and the linear actuator 5 are all signal-connected through a signal processor.

[0022] In this embodiment, the staff can directly place the dropper on the loading ring composed of the pressure cylinder 2 and the arc-shaped plate 3. Then, the rotary driving device 6 drives the turntable 7 to rotate. When rotating, the rotary driving device 9 drives the clamping plate 10 to deflect, so that after the material-changing ring composed of the receiving bracket 8 and the clamping plate 10 rotates and overlaps with the loading ring, only the receiving plate 8 contacts the dropper. Then, the rotary driving device 9 drives the clamping plate 10 to rotate back to form a material-changing ring with the receiving bracket 8, and the linear actuator 5 drives the sealing plate 4 to move in the pressure cylinder 2, so that the two arc-shaped plates 3 contract, and thus the dropper can be automatically taken away by the material-changing ring on the turntable 7 to achieve automatic feeding. When the dropper is transferred from the loading ring to the material-changing ring, the wider clamping part at the top round edge of the dropper slides from the loading ring to the material-changing ring; while the dropper is transferred from the loading ring to the material-changing ring, the extrusion mechanism starts to extrude the previously loaded dropper, and the blanking mechanism replaces the extruded dropper, so as to empty the material-changing ring for the next feeding.

[0023] In some embodiments, to achieve the purpose of automatically removing the droppers on the material-changing ring, a blanking mechanism is provided, which includes a guide rail 14. A plurality of sliding seats 15 are installed at the output end of the guide rail 14. A driving servo motor is installed inside the sliding seat 15, enabling the sliding seat 15 to move on the guide rail 14. A linear actuator three 16 is installed on the sliding seat 15. The linear actuator three 16 can be an electric cylinder. A blanking ring 17 is installed at the output end of the linear actuator three 16. The sliding seat 15 drives the linear actuator three 16 thereon to move on the guide rail 14 to the position below the material-changing ring. Then, the linear actuator three 16 lifts the blanking ring 17 to clamp the dropper. After that, the rotation driving device two 9 drives the two clamping plates 10 to separate, so that the sliding seat 15 can take away the dropper.

[0024] In some embodiments, to facilitate the extrusion of the droppers, an extrusion mechanism is provided, which includes a linear actuator two 11 and a liquid dripping plate 12. The linear actuator two 11 can be an electric cylinder. The linear actuator two 11 is installed on the frame 1. An extrusion plate 13 is installed at the output end of the linear actuator two 11. The liquid dripping plate 12 is placed on the frame 1 and is located below the extrusion plate 13. The linear actuator two 11 drives the extrusion plate 13 to move downward, so as to cooperate with the material-changing ring to abut against the dropper, enabling the liquid to drip on the liquid dripping plate 12.

[0025] In some embodiments, to facilitate the improvement of efficiency, the extrusion mechanism and the pressure cylinder 2 are respectively located on both sides of the turntable 7. Thus, while the dropper is transferred from the carrier ring to the material-changing ring, the extrusion mechanism extrudes the previously loaded dropper, so that the turntable 7 stops rotating once to complete two tasks.

[0026] In some embodiments, to facilitate the protection of the droppers, an arc-shaped cotton strip 18 is installed on the receiving frame 8.

[0027] In some embodiments, to facilitate the removal of the dropper when the sliding seat 15 moves on the guide rail 14, the guide rail 14 can be an elliptical guide rail or a square guide rail with arc-shaped corners.

[0028] In some embodiments, to enable the linear actuator three 16 to smoothly drive the blanking ring 17 to receive the dropper, the distance between the blanking ring 17 and the receiving frame 8 is greater than the length of the dropper.

[0029] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
