Description

Technical Field

[0001] This application relates to the field of sulfur hexafluoride density meter technology, and in particular to a relative cavity sulfur hexafluoride density meter inflation system, method, product and terminal. Background Technology

[0002] In the precision instrument industry, sulfur hexafluoride density meters are mainly used to monitor the density of sulfur hexafluoride gas in sealed containers. They can display the gas density on-site and provide timely alarms when the density value reaches the set value, making them suitable for high-pressure system testing. Among them, relative cavity sulfur hexafluoride density meters that employ the gas compensation principle are increasingly favored by customers due to their higher setpoint accuracy and greater shock resistance.

[0003] The core component of a relative cavity sulfur hexafluoride density meter is a bellows assembly. A predetermined gas, including SF6, N2, and C4, is filled into the gas chamber formed by the bellows assembly to achieve gas compensation, and then sealed with steel balls. However, the existing filling process for relative cavity sulfur hexafluoride density meters is mainly manual, using simple filling fixtures. This requires manual setting of the filling pressure, manual clamping and sealing, and manual pressing of the steel balls with a bench vise. This process is not only cumbersome but also results in poor consistency between filling and pressing, leading to high filling costs, low efficiency, and a relatively high rate of defective products. Furthermore, any abnormal filling value can prevent the bellows assembly or even the finished meter from being properly adjusted, resulting in scrap and significant cost losses. This makes it unsuitable for mass production of density relays and reduces its competitiveness in the precision instrument market. Summary of the Invention

[0023] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0024] Before providing a further detailed description of the present invention, the nouns and terms used in the embodiments of the present invention are explained, and the nouns and terms used in the embodiments of the present invention are subject to the following interpretations:

[0025] <1> Meters: These are instruments that measure a physical quantity and convert it into a displayed value, such as gas relays, pressure gauges, and gas density meters.

[0026] The existing filling process for relative cavity sulfur hexafluoride density meters is mainly manual, using simple filling fixtures. This requires manual setting of the filling pressure, manual clamping and sealing, and manual pressing of the steel balls using a bench vise. This process is not only cumbersome but also results in poor consistency between filling and steel ball pressing, leading to high filling costs, low efficiency, and a relatively high rate of defective products. Furthermore, any abnormal filling value can prevent the bellows assembly or even the finished meter from being properly adjusted, resulting in scrap and significant cost losses. This process also fails to meet the needs of mass-produced, customized density relays, making them uncompetitive in the precision instrument market.

[0027] To address the problems mentioned above, this invention provides a gas filling system, method, product, and terminal for a relative cavity sulfur hexafluoride density meter, aiming to solve the technical problems of high cost, low efficiency, and low yield caused by the manual operation of filling and sealing the relative cavity sulfur hexafluoride density meter in the prior art.

[0028] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 Detailed explanation. Figure 1 A schematic diagram of the relative cavity sulfur hexafluoride density meter inflation system 100 is shown in an embodiment of the present invention. The relative cavity sulfur hexafluoride density meter inflation system 100 includes: inflation fixture 101, inflation pressure steel ball module 102, air supply module 103, vacuum pumping module 104, steel ball discharge module 105, image acquisition module 106, and intelligent control module 107.

[0029] The pneumatic steel ball module 102 is connected to the pneumatic tooling 101, the air supply module 103, the vacuum extraction module 104, and the steel ball discharge module 105 via pipes; the intelligent control module 107 is electrically connected to the pneumatic steel ball module 102, the air supply module 103, the vacuum extraction module 104, the steel ball discharge module 105, and the image acquisition module 106.

[0030] Specifically, the inflation fixture 101 holds a product to be inflated; wherein the product to be inflated is a semi-finished product of relative cavity sulfur hexafluoride density table.

[0031] The steel ball discharge module 105 is used to transport sealed steel balls to the inflatable steel ball module 102.

[0032] The image acquisition module 106 is used to acquire the process card QR code image data of the product to be inflated;

[0033] The intelligent control module 107 is used to set the inflation process parameters of the product to be inflated based on the collected process card QR code image data, and according to the set inflation process parameters, it sequentially controls the inflation pressure steel ball module 102 to deliver sealing steel balls into the product to be inflated, controls the vacuum pumping module 104 to pump air from the product to be inflated through the inflation pressure steel ball module 102, controls the air supply module 103 to inflate the product to be inflated through the inflation pressure steel ball module 102, and controls the inflation pressure steel ball module 102 to press sealing steel balls into the product to be inflated.

[0034] In this embodiment, the inflation fixture 101 has multiple clamps, which can simultaneously fix multiple semi-finished sulfur hexafluoride density tables with the same inflation process information as products to be inflated. This enables batch inflation of multiple semi-finished sulfur hexafluoride density tables with the same inflation process information, effectively improving the speed and efficiency of the inflation process. Furthermore, a photoelectric sensor can be installed on the inflation fixture 101 to detect whether there are products to be inflated on the fixture. The photoelectric sensor is electrically connected to the intelligent control module 107. When the light emitted by the photoelectric sensor comes into contact with the product to be inflated fixed on the inflation fixture 101, the photoelectric sensor will trigger a signal, indicating that there is a product to be inflated fixed on the inflation fixture 101.

[0035] In this embodiment, in response to the trigger signal fed back by the photoelectric sensor, the clamp is controlled to clamp and fix the product to be inflated. After the product to be inflated is fixed, the intelligent control module 107 controls the steel ball discharging module 105 to transport the sealing steel balls to the inflation pressure steel ball module 102.

[0036] In this embodiment, the image acquisition module 106 includes a camera; the camera is used to scan the QR code of the process card of the product to be inflated within the camera's capture range, and to acquire the QR code image data of the process card.

[0037] It should be noted that each relative cavity sulfur hexafluoride density meter has a corresponding process card QR code. The process card QR codes for relative cavity sulfur hexafluoride density meters in the same batch may be identical. Therefore, multiple relative cavity sulfur hexafluoride density meters with the same process card QR code can be batch-filled with gas-pressurized steel balls for sealing. The process card QR code encodes the information on the process card (including the filling equipment, tools, and materials required for the filling process, and detailed explanations of the filling steps, methods, precautions, and safety requirements) into a QR code. By scanning the process card QR code with the camera, filling process information related to the filling process can be accurately obtained, allowing for strict control of each operational step and product quality during the filling process. Furthermore, the automatic product QR code recognition technology intelligently obtains the filling process information of the product to be filled, avoiding filling errors caused by manual setting of gas type and pressure, making it more accurate and with a lower error rate than manual operation.

[0038] It is worth noting that the relative cavity sulfur hexafluoride density meter filling system of the present invention, by setting up an intelligent control module 107, transforms the original inefficient process that could only be manually operated into an intelligent and automated process of filling and pressing steel balls through QR code image recognition technology, automated control technology, and software interaction. This greatly improves the efficiency and accuracy of the relative cavity sulfur hexafluoride density meter filling process, avoids the generation of defective products caused by improper tooling sealing or improper pressing of steel balls due to human operation factors, improves production efficiency and the yield of relative cavity sulfur hexafluoride density meters, and thus effectively improves the factory's revenue and market competitiveness.

[0039] In this embodiment, the intelligent control module 107 sets the inflation process parameters of the product to be inflated based on the collected process card QR code image data in the following ways:

[0040] (1) The process card QR code image data of the product to be inflated, which is acquired by the image acquisition module, is parsed and the inflation process information related to the inflation process is identified.

[0041] (2) Based on the inflation process information, set the inflation process parameters of the product to be inflated; wherein the inflation process parameters include: vacuum degree parameters, inflation hole position parameters, sealing hole position parameters, type of gas to be inflated and pressure parameters corresponding to the gas to be inflated.

[0042] In this embodiment, the type and proportion of gas injected into the product to be inflated can be guaranteed according to the inflation process parameters, thereby meeting the inflation process requirements and ensuring the product quality of the product to be inflated.

[0043] In this embodiment, by utilizing QR code image recognition technology, the present invention eliminates the need for manual data input or process control. Instead, it automatically scans and reads inflation process information and sets the inflation process parameters, significantly reducing manual operation steps, improving work efficiency, minimizing human intervention time, and avoiding problems caused by incorrect process parameter settings due to human data input errors. This enhances the accuracy and reliability of the inflation process. Precise control of inflation process parameters ensures the stability and consistency of the inflation process, contributing to improved product quality and consistency, while also helping to reduce production costs and waste.

[0044] In this embodiment, as Figure 2 The diagram shows a schematic representation of the intelligent control module in an embodiment of the present invention. The intelligent control module 107 includes at least a steel ball discharge control unit 1071, an air-pressurized steel ball control unit 1072, a vacuum extraction control unit 1073, and an air supply control unit 1074.

[0045] In this embodiment, the steel ball discharge control unit 1071 is used to control the steel ball discharge module 105 to transport sealed steel balls to the inflatable steel ball module 102. The steel ball discharge module 105 includes a hopper for holding sealed steel balls, a pusher bar disposed in the hopper, a cylinder connected to the pusher bar, a conveyor belt connected to the hopper pipe, and a drive mechanism; the cylinder and drive mechanism are electrically connected to the steel ball discharge control unit 1071. After the product to be inflated is fixed, the steel ball discharge control unit 1071 controls the reciprocating motion of the cylinder to push the pusher bar to push the sealed steel balls out of the hopper and transport them to the conveyor belt, and controls the drive mechanism to drive the conveyor belt to transport the sealed steel balls to the inflatable steel ball module 102.

[0046] In this embodiment, the inflation pressure steel ball control unit 1072 is connected to the steel ball discharge control unit 1071. After the steel ball discharge module 105 delivers the sealing steel ball to the inflation pressure steel ball module 102, it controls the inflation pressure steel ball module 102 to deliver the sealing steel ball into the product to be inflated according to the inflation hole position parameters. After the product to be inflated is filled with all the gas to be filled, it controls the inflation pressure steel ball module 102 to press the sealing steel ball into the sealing hole of the product to be inflated.

[0047] In this embodiment, the inflatable steel ball module 102 includes an inflation head and an electromagnet disposed on the inflation head. Gas channels are provided on both sides of the inflation head; the gas channels are respectively connected to the gas supply module and the vacuum pumping module; the electromagnet is electrically connected to the intelligent control module. The intelligent control module 107 controls the inflatable steel ball module 102 to deliver sealed steel balls into the product to be inflated based on the inflatable steel ball control unit 1072, including the following methods:

[0048] (1) When the sealing steel ball is detected to be delivered to the inflation pressure steel ball module, the electromagnet is energized so that the inflation head generates magnetism and the sealing steel ball is attracted to the head of the inflation head.

[0049] (2) According to the set inflation hole position parameters, control the inflation head to move into the inflation hole of the product to be inflated.

[0050] In this embodiment, the inflation head is also equipped with a displacement sensor, which is electrically connected to the inflation pressure steel ball control unit 1072. Based on the position data of the inflation head transmitted from the displacement sensor and the set inflation hole position parameters, the inflation pressure steel ball control unit 1072 controls the inflation head to move the sealing steel ball adsorbed on its head towards the inflation hole. The inflation head stops moving after it reaches the inflation hole of the product to be inflated. A sealing ring fitted on the inflation head seals the side of the inflation hole. Because the size of the sealing steel ball is smaller than the size of the inflation hole, the sealing steel ball does not block the inflation hole. Therefore, the gas to be inflated can smoothly enter the product through the gas channels on both sides of the inflation head, preventing air leakage during inflation and ensuring the efficiency and accuracy of the inflation process for the relative cavity sulfur hexafluoride density meter.

[0051] In this embodiment, the inflation head is also equipped with a drive motor, which is electrically connected to the inflation pressure steel ball control unit 1072. The inflation pressure steel ball control unit 1072, based on the position data of the inflation head transmitted from the displacement sensor and the set inflation hole position parameters, drives the inflation head via the drive motor to move the sealing steel ball adsorbed on its head towards the inflation hole.

[0052] In this embodiment, as Figure 3The diagram shows another structural schematic of the relative cavity sulfur hexafluoride density gauge inflation system in an embodiment of the present invention. The relative cavity sulfur hexafluoride density gauge inflation system 100 further includes: a pressure monitoring module 108; the gas supply module 103 and the vacuum pumping module 104 are both connected to the inflation pressure ball module 102 via pipelines through the pressure monitoring module 108; the pressure monitoring module 108 includes a pressure gauge and a second solenoid valve; the pressure gauge and the second solenoid valve are electrically connected to the intelligent control module 107, and are connected to the inflation pressure ball module 102 sequentially via pipelines in the order of pressure gauge and second solenoid valve.

[0053] In this embodiment, the vacuum pumping control unit 1073 is connected to the inflation pressure steel ball control unit 1072. After the inflation head moves into the inflation hole of the product to be inflated, the vacuum pumping module 104 controls the inflation pressure steel ball module 102 to pump air from the product to be inflated according to the vacuum degree parameter, so as to form a vacuum inside the product to be inflated.

[0054] In this embodiment, the vacuum pumping module 104 includes a vacuum pump and a third solenoid valve. The third solenoid valve is electrically connected to the intelligent control module 107 and is connected to the inflation pressure ball module 102 in the order of vacuum pump, third solenoid valve, pressure gauge, and second solenoid valve via pipelines. The intelligent control module 107 controls the vacuum pumping module 104 to evacuate the product to be inflated via the inflation pressure ball module 102, based on the vacuum pumping control unit 1073, in the following ways:

[0055] (1) Control the second solenoid valve and the third solenoid valve to open, and start the vacuum pump according to the set vacuum parameters. Continuously pump air from the product to be inflated through the gas channels on both sides of the inflation head, and monitor the vacuum value of the gas inside the product to be inflated through the pressure gauge.

[0056] (2) When the vacuum value reaches the set vacuum parameter, control the second solenoid valve and the third solenoid valve to close, and shut down the vacuum pump.

[0057] In this embodiment, the gas supply control unit 1074 is connected to the vacuum pumping control unit 1073. After a vacuum is formed inside the product to be inflated, the gas supply module 103 controls the gas supply module 103 to sequentially inflate all the gases to be inflated into the product through the inflation pressure ball module 102, according to the type of gas to be inflated and the corresponding pressure parameters.

[0058] In this embodiment, the gas supply module 103 includes multiple gas cylinders containing different types of gas to be filled and multiple first solenoid valves. Each first solenoid valve is electrically connected to the intelligent control module 107 and is connected to the inflation pressure ball module 102 in the order of gas cylinder, first solenoid valve, pressure gauge, and second solenoid valve via pipeline. The intelligent control module 107 controls the gas supply module 103 to inflate the product to be filled via the inflation pressure ball module 102 based on the gas supply control unit 1074, including the following methods:

[0059] (1) Control the second solenoid valve to open, and control the first solenoid valve connected to the corresponding gas tank to open according to the type of gas to be filled, so as to start the gas to be filled in the gas tank to be automatically filled into the product to be filled based on the air pressure through the gas channels on both sides of the filling head, and monitor the pressure value of the gas to be filled in the product to be filled by the pressure gauge.

[0060] (2) When the pressure value of the gas to be filled reaches the set corresponding pressure parameter, control the second solenoid valve to close and the first solenoid valve connected to the gas tank to close.

[0061] In this embodiment, when the product to be inflated needs to be filled with multiple gases, after each inflating of the product with one type of gas, the third solenoid valve is opened to extract the remaining gas in the pipeline, and then the third solenoid valve is closed. Then, the next type of gas is inflated, and the second solenoid valve and the first solenoid valve connected to the corresponding gas tank are opened to automatically inflate the product with the gas from that gas tank through the gas channels on both sides of the inflator head based on air pressure. The pressure value of the gas in the product is monitored by the pressure gauge. When the pressure value of the gas reaches the set corresponding pressure parameter, the second solenoid valve and the first solenoid valve connected to the gas tank are closed. This process is repeated to complete the inflating of all gases in the product.

[0062] In this embodiment, a heat exchanger is also provided between the gas tank and the first solenoid valve to ensure that the gas to be filled into the product has a stable temperature.

[0063] It should be noted that during the automatic inflation process, the pressure value of the gas to be inflated is monitored by a pressure gauge, and the inflation error is controlled within 0.005MPa, ensuring the accuracy of the inflation pressure and the compensation accuracy of the product to be inflated.

[0064] In this embodiment, the inflation pressure steel ball control unit 1072, after all the gas to be filled into the product to be inflated, controls the inflation pressure steel ball module 102 to press the sealing steel ball into the sealing hole of the product to be inflated. The intelligent control module 107, based on the inflation pressure steel ball control unit 1072, controls the inflation pressure steel ball module 102 to press the sealing steel ball into the product to be inflated in the following ways: controlling the first, second, and third solenoid valves to close, and controlling the inflation head to move the sealing steel ball into the sealing hole of the product to be inflated according to the set sealing hole position parameters, so as to press the sealing steel ball into the sealing hole for sealing.

[0065] In this embodiment, the inflation pressure steel ball control unit 1072, based on the position data of the inflation head returned by the displacement sensor and the set sealing hole position parameters, drives the inflation head through the drive motor to move the sealing steel ball adsorbed on its head toward the sealing hole of the product to be inflated, and stops after the inflation head moves into the sealing hole, pressing the sealing steel ball into the sealing hole to seal.

[0066] It is worth noting that the relative cavity sulfur hexafluoride density meter inflation system of the present invention, through automated control technology, not only completes the intelligent and automated transformation of the inflation process, but also prevents air leakage during inflation by precisely controlling the position of the inflation head, and avoids defects such as incomplete steel ball pressing due to deformation or damage of the inflation head. This ensures the efficiency, accuracy, stability and consistency of the relative cavity sulfur hexafluoride density meter inflation process, improves production efficiency and the yield of relative cavity sulfur hexafluoride density meters, helps to improve product quality and consistency, and also helps to reduce production costs and waste, thereby effectively improving the factory's profits and market competitiveness.

[0067] Furthermore, by transmitting control signals to the vacuum pump, various solenoid valves, and pressure gauges via electrical connection, signal quality and transmission efficiency are ensured, comprehensively improving the efficiency and accuracy of the inflation process and resulting in a higher yield of the products to be inflated.

[0068] In this embodiment, the relative cavity sulfur hexafluoride density gauge inflation system 100 further includes a laser marking module connected to the intelligent control module. This module controls the laser marking module to mark a traceability code on the product after inflation and steel ball pressing, ensuring each product has a unique traceability code for easy future tracking. The intelligent control module records and saves information such as the product's traceability code, inflation gas, corresponding inflation pressure, steel ball pressing stroke, and steel ball pressing force, enabling accurate tracking of key information such as the product's production process, raw material source, production batch, and production date. When product quality issues arise, the source of the problem can be quickly located, reducing the recall scope and minimizing losses.

[0069] It should be understood that the inflation system for the relative cavity sulfur hexafluoride density gauge provided in any of the above embodiments, when inflating the product to be inflated, is only illustrated by the division of the above-described program modules. In practical applications, the above processing can be assigned to different program modules as needed, that is, the internal structure of the system can be divided into different program modules to complete all or part of the processing described above. This invention does not limit this.

[0070] To better describe the specific structure of the relative cavity sulfur hexafluoride density meter inflation system, the connection relationship between the various structures, and the function of each structure, the present invention provides a specific embodiment to further illustrate the relative cavity sulfur hexafluoride density meter inflation system.

[0071] Example: A relative cavity sulfur hexafluoride density gauge inflation system.
