Description

Technical Field

[0001] This utility model relates to the field of sample vial disassembly, specifically to an ion chromatography sample vial disassembly system. Background Technology

[0002] Ion chromatography is a technique that uses ion exchange mechanisms to separate and analyze ion mixtures. Its basic principle is to achieve separation by allowing ions to exchange between the stationary and mobile phases through ion exchange between the stationary and mobile phases. Ion chromatography can be classified into cation exchange chromatography, anion exchange chromatography, ion-pair chromatography, and ion repulsion chromatography based on different ion exchange mechanisms. Ion chromatography is widely used in environmental monitoring, food analysis, natural water industry, agriculture, geology, and many other fields. For example, it can be used to determine anions such as fluoride, chloride, and sulfate, as well as cations such as sodium, potassium, calcium, and magnesium in water samples.

[0003] After the samples are tested, a large number of used sample bottles need to be cleaned. Before cleaning, the sample bottle cap remover needs to be manually pressed against the sample bottle cap 101, manually rotated downwards, and after the thread is locked, the sample bottle cap 101 needs to be pulled out forcefully. The sample bottle cap remover is then reversed to separate it from the sample bottle cap 101. The above operation is repeated continuously to separate the sample bottle and the sample bottle cap 101 for the next cleaning step. The operation is time-consuming and laborious, which greatly increases the workload of the testers and reduces work efficiency. Utility Model Content

[0004] This invention provides an ion chromatography sample vial disassembly system, which aims to solve the complex technical problems of disassembling multiple ion chromatography sample vials before cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ion chromatography sample vial disassembly system includes: a rotating base for holding ion chromatography sample vials, a robotic arm mounted at the center of the rotating base, a rotary motor fixed to the robotic arm, a cap-removing cylinder fixed to the housing of the rotary motor, a fixed connecting cylinder for abutting the ion chromatography sample vials, and a fixed ring for abutting the cap of the sample vials inside the fixed connecting cylinder.

[0007] The output end of the rotary motor is vertically downward and connected to a telescopic rod. The output end of the telescopic rod extends downward beyond the cap-removing cylinder and the fixing cylinder, and has a threaded structure at the end for screwing on the sample bottle cap.

[0008] Preferably, the inner diameter of the fixing ring is smaller than that of the sample bottle cap.

[0009] Preferably, the outer diameter of the fixed connector is matched with the inner diameter of the ion chromatography sample vial.

[0010] Preferably, the rotating base includes a rotating ring platform, with multiple placement slots circumferentially opened on the top of the rotating ring platform and teeth surrounding the side. A drive motor is provided on one side of the rotating ring platform, and the output end of the drive motor is connected to a gear that matches the teeth.

[0011] Preferably, a robotic arm is mounted at the center of the rotating base via a bearing. The robotic arm is an existing structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The robotic arm automatically aligns the cap-removing cylinder and the fixing cylinder with the center of the sample bottle cap on the ion chromatography sample bottle, and moves downward until the fixing cylinder abuts against the bottle opening and holds the sample bottle in place. The output of the rotary motor rotates clockwise, causing the threaded structure of the telescopic rod to engage with the internal thread of the sample bottle cap. The telescopic rod retracts upward until the sample bottle cap separates from the ion chromatography sample bottle. The telescopic rod continues upward until it reaches the fixing ring. The output of the rotary motor then rotates counterclockwise until the sample bottle cap separates from the threaded structure and rests on the bottle opening. This completes the disassembly process for one ion chromatography sample bottle and cap. The rotating base then automatically rotates to the next sample bottle cap to begin the next disassembly process. This invention can continuously complete the disassembly of a large number of ion chromatography sample bottles and caps, saving significant disassembly time, simplifying operation, and improving work efficiency.

Detailed Implementation

[0019] A preferred embodiment of the present invention will now be described in conjunction with the accompanying drawings, providing a clear and complete description of the technical solution in this preferred embodiment.

[0020] An ion chromatography sample vial disassembly system includes: a rotating base 1 for holding an ion chromatography sample vial 100, a robotic arm 2 mounted at the center of the rotating base 1, a rotary motor 3 fixed to the robotic arm 2, a cap-removing cylinder 4 fixedly connected to the outer shell of the rotary motor 3, a fixing connecting cylinder 5 for abutting the ion chromatography sample vial 100, and a fixing ring 51 for abutting the sample vial cap 101 inside the fixing connecting cylinder 5.

[0021] The output end of the rotary motor 3 is vertically downward and connected to a telescopic rod 6. The output end of the telescopic rod 6 extends downward beyond the cap-removing cylinder 4 and the fixed connecting cylinder 5, and has a threaded structure 61 at the end for screwing the sample bottle cap 101.

[0022] Through the above design, when using this disassembly device, the used ion chromatography sample vial 100 with sample vial cap 101 is inserted into the rotating base 1. Up to 12 ion chromatography sample vials 100 can be placed at a time. After the robotic arm 2 is switched on, the robotic arm 2 automatically aligns the cap-removing cylinder 4 and the fixing cylinder 5 with the center of the sample vial cap 101 on the ion chromatography sample vial 100, and moves downwards until the fixing cylinder 5 abuts against the mouth of the ion chromatography sample vial 100 and fixes the ion chromatography sample vial 100 stationary. The output end of the rotary motor 3 rotates clockwise 3 times. The threaded structure 61 of the telescopic rod 6 engages with the internal thread of the sample vial cap 101. The telescopic rod 6 retracts upward until the sample vial cap 101 separates from the ion chromatography sample vial 100. The telescopic rod 6 continues upward until it reaches the fixing ring 51. The output end of the rotary motor 3 rotates counterclockwise 3 times until the sample vial cap 101 separates from the threaded structure 61 and falls onto the opening of the ion chromatography sample vial 100. The disassembly process of one ion chromatography sample vial 100 and sample vial cap 101 is completed. The rotating base 1 automatically rotates to the next sample vial cap 101 to begin the next disassembly process.

[0023] Specifically, the inner diameter of the fixing ring 51 is smaller than that of the sample bottle cap 101. The outer diameter of the fixing sleeve 5 matches the inner diameter of the ion chromatography sample bottle 100.

[0024] Through the above design, the outer diameter of the fixing sleeve 5 of the cap-removing sleeve 4 matches that of the ion chromatography sample bottle 100. When the robotic arm 2 moves the cap-removing sleeve 4 downward, it can press against the mouth of the ion chromatography sample bottle 100 to keep it stationary. At the same time, it can provide support when the telescopic rod 6 tightens or pulls out the sample bottle cap 101. The inner diameter of the fixing ring 51 of the fixing sleeve 5 is slightly smaller than that of the sample bottle cap 101, so it can provide support when the telescopic rod 6 loosens the sample bottle cap 101.

[0025] Specifically, the rotating base 1 includes a rotating ring platform 11, with multiple placement slots 12 circumferentially opened on the top of the rotating ring platform 11 and teeth 13 surrounding the side. A drive motor 14 is provided on one side of the rotating ring platform 11, and a gear 15 matching the teeth 13 is connected to the output end of the drive motor 14.

[0026] Specifically, a mechanical arm 2 is mounted on the center of the rotating base 1 via a bearing.

[0027] Through the above design, the robotic arm 2 is an existing device that can realize the up and down movement of the rotary motor 3.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
