Description

Technical Field

[0001] This invention relates to the field of automated testing systems, and in particular to an automated receiving and sampling device for particulate samples. Background Technology

[0002] The analysis of samples of solid particulate materials (raw materials, semi-finished products, or finished products) is a crucial and essential task in many industries, including cement, metallurgy, chemicals, and food. It provides a strong basis for product quality control, and the results can guide relevant technical departments to optimize product formulation and processing, thereby improving final product performance and enhancing market competitiveness. Therefore, ensuring the accuracy and efficiency of product testing is of paramount importance.

[0003] Currently, many manufacturing companies' laboratories operate in a semi-automated, semi-manual manner. This means that laboratory technicians go to the site to collect samples, which are then taken to the laboratory, weighed, and placed into the appropriate equipment before further processing. Therefore, technicians need to repeatedly travel between the site and the laboratory, which is time-consuming and labor-intensive, and the dust can be harmful to their health. Furthermore, the manual inspection process presents challenges in maintaining consistent sample quality, leading to subjective and inaccurate evaluations.

[0004] In recent years, with the development of automation and intelligent technologies, some domestic enterprises have begun to automate their laboratories, adopting foreign automated testing equipment and systems. These include: on-site automatic sampling systems, automatic sending systems, automatic conveying systems, automatic receiving systems, automatic grinding and slide preparation equipment, transport robot systems, automatic analysis systems, and automatic management systems. The upgraded laboratories boast a high degree of automation, with fully digital intelligent control, eliminating the need for human intervention and avoiding human error, thus significantly improving testing efficiency and accuracy. However, foreign automatic sampling and receiving systems suffer from drawbacks such as complex structures, large space requirements for delivery pipelines, high costs, and stringent requirements on the dimensions of sample transport boxes. Meanwhile, domestically produced fully automated sending systems are not yet mature and in mass production. Summary of the Invention

[0034] Example

[0035] Please see Figures 1-4This invention provides an automated particle sample receiving and sampling device, which consists of a frame 1-4, a receiving opening / closing cover mechanism 1-1, a sample quantification mechanism 1-2, and a sample sampling mechanism 1-3.

[0036] Frames 1-4 are used to support various mechanisms within the device and are mounted on support bases 4-6;

[0037] The receiving and opening / closing cover mechanism 1-1 is located on the upper part of the frame 1-4 and is used to receive and open / close the sample box 3-3;

[0038] The sample quantification mechanism 1-2 is located below the receiving open / closed cover mechanism 1-1 and is used to quantitatively obtain the experimental sample inside the receiving open / closed cover mechanism 1-1.

[0039] The sample sampling mechanism 1-3 is located below the sample quantification mechanism 1-2 and is used to hold the experimental sample obtained by the sample quantification mechanism 1-2 in a small cup.

[0040] Specifically, the receiving / opening / closing mechanism 1-1 is located on the top layer of the device and is mainly used for receiving and opening / closing sample boxes 3-3. It includes a fixed cylinder 2-2, a movable cylinder 2-4, and a sample box lifting cylinder 2-6. The fixed cylinder 2-2 is mounted on the frame 1-4. Optical photoelectric switches 2-1 are installed on both sides of the upper part of the fixed cylinder 2-2 to detect whether a sample box 3-3 has passed by. Clamping cylinders 2-3 for clamping the sample box 3-3 are installed on both sides of the fixed cylinder 2-2. The movable cylinder... The movable cylinder 2-4 is located directly below the fixed cylinder 2-2. On both sides of the movable cylinder 2-4 are respectively installed lid clamping cylinders 2-5 for clamping the lid of the sample box 3-3. The lid clamping cylinders 2-5 and 2-3 together clamp the sample box 3-3, preparing for the opening / closing of the sample box 3-3. Both the two lid clamping cylinders 2-3 and 2-5 are connected in series with a dual-cylinder structure, ensuring precise and synchronized action and sufficient opening and closing force. The lower part of the movable cylinder 2-4 is connected to the feed pipe 2-7, which is connected to the sample quantitative mechanism 1-2. The fixed cylinder 2-2, the movable cylinder 2-4, and the sample quantitative mechanism 1-2 are sequentially and sealed together. The movable cylinder 2-4 is mounted on the tray of the sample box lifting cylinder 2-6. The movable cylinder 2-4 is driven to move up and down by the sample box lifting cylinder 2-6 to open / close the sample box 3-3. The sample box lifting cylinder 2-6 is mainly used as the power source for opening / closing the sample box 3-3.

[0041] The upper end of the movable cylinder 2-4 is slidably connected to the fixed cylinder 2-2, and an upper sealing ring 3-1 is provided at the connection. The feed pipe 2-7 is slidably connected to the sample volume metering groove 4-8 of the sample metering mechanism 1-2, and a lower sealing ring 3-2 is provided at the connection. This allows the movable cylinder 2-4 to move up and down under the action of the sample box lifting cylinder 2-6, maintaining a seal between itself and the fixed cylinder 2-2 and the sample volume metering groove 4-8. In this embodiment, the upper sealing ring 3-1 is installed in the sealing groove on the inner side wall of the outlet of the fixed cylinder 2-2, and the lower sealing ring 3-2 is installed in the sealing groove on the inner side wall of the inlet of the sample volume metering groove 4-8.

[0042] The movable cylinder 2-4 is provided with compressed air pipeline interfaces 2-9 around its perimeter for introducing compressed air into the movable cylinder 2-4 to flush residual waste and assist in the delivery of sample box 3-3. Pneumatic vibrators 2-8 are also installed on the movable cylinder 2-4 and the sample volume metering tank 4-8 ​​to prevent blockage of the feed pipe 2-7 and the sample volume metering tank 4-8.

[0043] The sample quantification mechanism 1-2 is located on the second layer of the frame 1-4, and includes a sample volume quantification tank 4-8, a first cylinder 4-1, and a second cylinder 4-2. The inlet of the sample volume quantification tank 4-8 ​​is connected to the outlet of the feed pipe 2-7 of the receiving opening / closing mechanism 1-1. The first cylinder 4-1 and the second cylinder 4-2 are arranged vertically and are both installed on the sample volume quantification tank 4-8. The blade of the first cylinder 4-1 and the blade of the second cylinder 4-2 are slidably and sealingly connected to the inner wall of the sample volume quantification tank 4-8 ​​to realize the quantitative acquisition of experimental samples. The sample quantification adopts the principle of volume quantification. The feed tube 2-7 at the bottom of the receiving / closing mechanism 1-1 sends the experimental sample along the feed tube 2-7 to the sample volume quantification groove 4-8 of the sample quantification mechanism 1-2 by gravity. The upper and lower cylinders drive the gate blade to perform volume quantification, thereby realizing sample quantification. Opening the lower gate blade realizes the accurate acquisition of a fixed volume of experimental sample.

[0044] The sample collection mechanism 1-3 includes a small cup 4-3 and a cup-lifting cylinder 4-5. The small cup 4-3 is located on the cup-lifting cylinder 4-5, which is supported and fixed to the frame 1-4 by a cylinder-lifting bracket 4-7. The cup-lifting cylinder 4-5 drives the cup-lifting cylinder to move up and down, so that the small cup 4-3 can be pressed against the outlet of the sample quantitative mechanism 1-2. The sample collection mechanism 1-3 is located at the bottom layer and mainly collects the experimental samples obtained by the sample quantitative mechanism 1-2 through the small cup 4-3. Before filling, the cup-lifting cylinder 4-5 holds the small cup 4-3 against the outlet of the sample quantitative mechanism 1-2. After the small cup 4-3 has received the sample, the cup-lifting cylinder 4-5 retracts, and finally, the small cup 4-3 is removed by an external robotic arm. The material cup lifting cylinder 4-5 is equipped with a waste conduit 4-4. One end of the waste conduit 4-4 is connected to an external dust removal device, and the other end can be pressed against the outlet of the sample quantitative mechanism 1-2 through the material cup lifting cylinder 4-5, so that it is connected to the sample quantitative structure and the feed pipe 2-7, thereby realizing that the residual waste is completely removed by the external dust removal device, ensuring the environment inside the pipe, so as to facilitate the next sample collection and prevent mixing.

[0045] This invention realizes an automated receiving, opening, quantification, sampling, and rinsing device. The entire process is controlled by a PLC, automatically receiving sample box 3-3, automatically opening sample box 3-3, automatically quantifying the sample, and automatically acquiring the sample. After sample collection, compressed air is automatically activated to rinse the pipeline. Finally, the sample box 3-3 is capped and automatically, accurately, and efficiently returned to the corresponding sampling site. This device has the advantages of compact structure, small footprint, and easy maintenance.

[0046] The following provides a detailed explanation of the entire process of the automated receiving-sampling device, from its static state to receiving sample box 3-3, from opening the lid to sampling, from rinsing inside the container to closing the lid, and finally to sending sample box 3-3 out. The specific process is as follows:

[0047] 1) The device is in a static state;

[0048] Before the sample box 3-3 is sent from the sending station to the automated receiving and sampling device through the pipeline, all electrical devices of the automated receiving and sampling device are in the off state except for the photoelectric switch 2-1.

[0049] 2) When the device receives sample box 3-3;

[0050] When sample box 3-3 is delivered to the automated receiving and sampling device, photoelectric switch 2-1 senses the passing of the object and triggers other equipment to start running. At this time, the fan that transports sample box 3-3 continues to be turned on. The fan is turned off only after sample box 3-3 has completely stopped on the moving cylinder 2-4 of the device.

[0051] 3) After the device receives sample box 3-3;

[0052] When the lid clamping cylinder 2-5 of the movable cylinder 2-4 starts to operate, the movement of its cylinder rod is detected by the magnetic induction device on the lid clamping cylinder 2-5. After the cylinder rod of the lid clamping cylinder 2-5 is fully extended, it is clamped in the annular groove at the lid of the sample box 3-3. Then, the bottom sample box lifting cylinder 2-6 is activated. After the cylinder rod of the sample box lifting cylinder 2-6 is fully extended, the box clamping cylinder 2-3 of the fixed cylinder 2-2 starts to operate. The movement of its cylinder rod is detected by the magnetic induction device on the box clamping cylinder 2-3. The action of the rod is such that when the cylinder rod of the box clamping cylinder 2-3 is fully extended and clamped in the annular groove at the box body of sample box 3-3, the sample box lifting cylinder 2-6 is closed and the cylinder rod of the sample box lifting cylinder 2-6 is retracted, thereby realizing the opening process of sample box 3-3; at the same time, the two pneumatic vibrators 2-8 installed on the sample volume quantitative groove 4-8 and the movable cylinder 2-4 are turned on, and the feed pipe 2-7 at the bottom of the opening / closing mechanism 1-1 transports the experimental sample into the sample quantitative mechanism 1-2.

[0053] 4) Quantitatively obtain and take samples for experiments;

[0054] Open cylinder 4-1 at the top of sample quantitative mechanism 1-2, hold for a period of time, and then close it again. Start the small cup 4-3 lifting cylinder to place the small cup 4-3 at the outlet of "sample quantitative mechanism 1-2". Then open cylinder 4-2 of sample quantitative mechanism 1-2. At this time, the experimental sample falls into the small cup 4-3. After all the experimental sample in sample volume quantitative tank 4-8 ​​has fallen into the small cup 4-3, close the cup lifting cylinder 4-5. Then, the robotic arm "takes" the small cup 4-3. This is recorded as the first sampling. If a second sampling is required, repeat this step. The number of samplings can be set (up to 8 times). After the robotic arm takes out the small cup 4-3 for the last time, proceed to the next step.

[0055] 5) Pipeline cleaning;

[0056] After the small sample cup 4-3 is removed, the sample cup lifting cylinder 4-5 is activated, causing the waste conduit 4-4 on the sample cup lifting cylinder 4-5 to press tightly against the outlet of the sample quantitative mechanism 1-2. Then, the external dust removal equipment is activated, and the first cylinder 4-1 and the second cylinder 4-2 on the sample quantitative mechanism 1-2 are simultaneously activated to remove any remaining waste through the external dust removal equipment. After a period of time, the sample box lifting cylinder 2-6 of the receiving open / close mechanism 1-1 is activated to complete the closing action of the sample box 3-3. The box clamping cylinder 2-3 and the... After the lid clamping cylinder 2-5 completes its action, the compressed air in the pipe of the movable cylinder 2-4 is turned on. After a period of time, the compressed air in the pipe of the movable cylinder 2-4 is turned off to complete the flushing of residual materials attached to the inside of the pipe and the outside of the sample box 3-3. This prevents the materials from causing dust and prevents the next sampling from being contaminated. Then, the pneumatic vibrator 2-8 is turned off. After the action is completed, the external dust removal equipment is turned off. The first cylinder 4-1 and the second cylinder 4-2 on the sample quantitative mechanism 1-2 are turned off. The cup lifting cylinder 4-5 of the sample sampling mechanism 1-3 is turned off.

[0057] 6) Sample boxes 3-3 sent;

[0058] Turn on the external fan (reverse valve switching), turn on the compressed air in the movable cylinder 2-4 pipe, and sample box 3-3 will be launched away from the device under the action of the airflow in the pipe. After photoelectric switch 2-1 senses again and gives a prompt, turn off the compressed air in the movable cylinder 2-4 pipe, and turn off the sample box lifting cylinder 2-6. The delivery of sample box 3-3 is complete. One workflow is finished.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
