Description

Technical Field

[0001] The present invention relates to the technical field of intelligent preparation of standard gas, and in particular to an intelligent preparation system of standard gas. Background Art

[0002] There are many kinds of standard gases, which are usually manually configured according to GB / T 5274.1-2018 "Preparation of mixed gases for gas analysis calibration Part 1: Preparation of primary mixed gases by weighing method". Multiple gases need to be filled in a certain proportion and sequence. This filling process is called "gas distribution", and the gases filled are called component gases.

[0003] The traditional gas distribution process is done manually, with low filling efficiency and prone to errors in gas metering. First of all, safety risks are a major consideration. Manual operation can easily lead to gas leakage, especially when connecting the gas cylinder valve, gas nozzle and quick connector. Careless operation or aging of equipment may cause leakage. In addition, different skill levels of operators may lead to incorrect mixing ratios, which in turn affects the accuracy and stability of the standard gas. Secondly, manual gas distribution is inefficient. The operation time is long, and valves need to be opened and closed and gas connections need to be made one by one, which is not only time-consuming but also increases the possibility of errors. Relying on the skills and experience of the operator, the accuracy of the distribution is difficult to control uniformly, and the skill levels of different operators and changes in environmental conditions can easily affect the final distribution results. In summary, these problems limit the scope and effect of traditional manual gas distribution methods in large-scale production and precision applications. Summary of the invention

It also includes a barcode scanning camera installed on the outside of the flexible clamp 2 for identifying the specifications and models of the gas cylinders.

[0010] Preferably, the workstation operation subsystem also includes a visual camera, which is installed on the outside of the identification station through a frame and is used to detect the position of the gas nozzle of the gas cylinder and cooperate with the rotating lifting platform under the identification station to ensure that the spatial position of the gas nozzle of the gas cylinder is the same each time it is loaded.

[0011] Preferably, the branch includes branch one installed on the outside of the main circuit for connecting to the component gas cylinders, and a pneumatic valve one, a filter and a manual valve are installed in sequence in the middle of the branch one. It also includes branch two, branch three, branch four and branch five for connecting the main circuit, and an exhaust gas outlet circuit connected to the main circuit, a pneumatic valve two and a vacuum pump are installed in sequence in the middle of the branch two, and a one-way valve is installed at the open end of the exhaust gas outlet circuit, a pneumatic valve three and a vacuum gauge sensor are installed in the middle of the branch four, and a pneumatic valve four is installed in the middle of the branch three.

[0012] Preferably, the gas filling subsystem also includes a safety valve 1 and a safety valve 2 installed in the middle of the main loop, and a pressure sensor and a throttle valve installed at the charging end of the main loop.

[0013] Preferably, the gas cylinder valve switch subsystem includes a linear motion module 1 installed on a frame, a rotating base installed at the execution end of the linear motion module 1, and a flexible clamp 1 installed at the execution end of the rotating base.

[0014] Preferably, the system also includes a quick-connect plug plug-in and pull-out subsystem, which is installed on the outside of the inflation station through a frame, and is used to connect the pipeline in the gas filling subsystem with the gas cylinder. It includes a linear motion module 2 installed on the frame, and the motion execution end of the linear motion module 2 is equipped with a plug clamp, and the execution end of the plug clamp is equipped with a quick-connect plug.

[0016] Preferably, the system also includes a safety monitoring subsystem, which includes a gas monitoring camera, a surveillance camera, and an alarm. The gas monitoring camera and the surveillance camera are installed on the outside of the frame, and the field of view can cover all other subsystems.

[0017] Working principle: The flexible gripper 2 on the gantry truss manipulator grips the gas cylinder to be filled in the loading area. At the same time, the scanning camera next to the flexible gripper 2 reads the QR code on the gas cylinder. The QR code carries information including the specifications and dimensions of the gas cylinder, the type and amount of the component gas to be filled, and this information is sent to the industrial computer, which records the specifications and dimensions of the gas cylinder filled this time, the type and amount of the component gas filled. The gantry truss manipulator moves the gas cylinder to the rotating lifting platform of the identification station. The visual camera measures the position of the gas nozzle of the gas cylinder, and locates the position of the gas nozzle in conjunction with the rotation of the rotating lifting platform to ensure that the spatial position of the gas nozzle of each loading gas cylinder is the same. Then the circular arc clamp is used to clamp the gas cylinder, and then the rotating lifting platform descends, the electric turntable rotates 180 degrees, and the gas cylinder is transferred to the filling station. With the cooperation of the rotating base and the linear motion module 1, the flexible gripper 1 can perform a compound movement of rotation and lifting to open the gas cylinder valve. The plug clamp clamps the fixed part of the quick-connect plug, moves upward or downward, aligns it with the gas nozzle, and then moves forward to insert the quick-connect plug into the gas nozzle. Pneumatic valve 1 in the gas filling circuit is opened and other pneumatic valves are closed. Component gas 1 enters the gas cylinder through the throttle valve. When the weight read by the electronic scale increases by a specified value, pneumatic valve 1 is immediately closed. The weight increase read by the electronic scale is the actual filling amount of component gas 1. Then pneumatic valve 2 and pneumatic valve 4 are opened, and flexible clamp 1 performs a compound movement of rotation and lifting to close the gas cylinder valve, turn on the vacuum pump, and extract the residual component gas 1 in the pipeline. At the same time, the vacuum gauge sensor monitors the exhaust situation. After the vacuum degree reaches the set value, the vacuum pump and gas are turned off. Pneumatic valve 2, pneumatic valve 4, and then the flexible gripper 1 performs a compound movement of rotation-lifting and opens the cylinder valve. The other pneumatic valve 1 opens, and the component gas 2 enters the cylinder through the throttle valve. When the weight read by the electronic scale increases by the set value, the pneumatic valve 1 is immediately closed. The weight increase read by the electronic scale is the actual filling amount of the component gas 2. The flexible gripper 1 performs a compound movement of rotation-lifting and closes the cylinder valve. The plug gripper is first clamped on the plug movable sleeve, gently pulled back, and then clamped on the fixed end of the plug, pulled back, and removed the quick-connect plug. The flexible gripper 2 on the gantry truss manipulator clamps the filled cylinder and puts it into the unloading area. The industrial computer records the actual filling amount of the component gas in this cylinder.

[0018] The present invention provides a standard gas intelligent preparation system, which has the following beneficial effects:

[0019] 1. The present invention can automatically complete the filling of gases of different components, greatly reduce the manual participation in gas distribution work, alleviate the manpower burden, and improve the accuracy of gas filling.

[0030] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] Please refer to the attached Figure 1 - Attachment Figure 3 The embodiment of the present invention provides a standard gas intelligent preparation system, including:

[0033] The station operation subsystem is used to adjust the gas cylinder and clamp and position it. It includes an identification station 6 for identifying the gas cylinder model and a gas filling station 8 symmetrically arranged therewith. The naming of the identification station 6 and the gas filling station 8 is not based on different structures, but on different spatial positions. After the identification station 6 rotates 180 degrees, it becomes the gas filling station 8. The electric turntable 5 carrying the identification station 6 and the gas filling station 8 rotates, and the gas cylinder can be operated between the identification station 6 and the gas filling station 8. The rotating lifting platform installed below the identification station 6, the arc clamp 7 for stabilizing the gas cylinder and the electronic scale installed below the gas filling station 8. When filling the gas, the change in the reading of the electronic scale reflects the quality of the gas filled. The electronic scale and the gas filling subsystem form a closed-loop control to accurately control the filling amount of each gas; each arc clamp 7 is composed of two semi-circular arc positioning blocks and a telescopic cylinder. When the gas cylinder is positioned and clamped, the telescopic cylinder retracts and the semi-circular arc positioning block is used to clamp the gas cylinder. It also includes a visual camera 9, which is installed outside the identification station 6 through a frame and is used to detect the position of the gas nozzle of the gas cylinder and cooperate with the rotating lifting platform under the identification station 6 to ensure that the spatial position of the gas nozzle of the gas cylinder loaded each time is the same. After the gas cylinder is loaded, it is placed on the rotating lifting platform and cooperates with the visual camera 9 to locate the position of the gas nozzle.

[0034] Please refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 7 The gas filling subsystem is used for automatic gas filling operations, which includes multiple component gas cylinders 16, a main circuit 17, multiple branches connected to the main circuit 17, pneumatic valves and a vacuum pump 26 installed on the main circuit 17 and the branches, and multiple status identification elements installed on the main circuit 17 and the branches.

[0035] Please refer to the attached Figure 7The branch includes a branch 18 installed outside the main circuit 17 for connecting with the component gas cylinder 16. The middle of the branch 18 is sequentially installed with a pneumatic valve 12, a filter 23 and a manual valve 24. The manual valve 24 is normally open. When the system is abnormal and the automatic valve cannot be closed, the valve can be manually closed to prevent accidents. The branch also includes a branch 2 19, a branch 3 20, a branch 4 21 and a branch 5 37 that connect the main circuit 17, and an exhaust gas outlet circuit 38 connected to the main circuit 17. The middle of the branch 2 19 is sequentially installed with a pneumatic valve 25 and a vacuum pump 26. The middle of the branch 3 20 is installed with a pneumatic valve 4 34. When the pressure value in the main circuit 17 reaches the set upper limit, the pneumatic valve 4 34 automatically opens and releases pressure under the control of the industrial computer as another safety protection. The middle of the branch 4 21 is installed with a pneumatic valve 3 27. The state identification element includes a one-way valve 33 installed at the open end of the exhaust gas outlet circuit 38, a vacuum gauge sensor 32 installed in the middle of the branch four 21, a safety valve 1 31 and a safety valve 2 35 installed in the middle of the main circuit 17. When the pressure value in the main circuit 17 reaches the set upper limit, the safety valve 2 35 automatically opens and releases pressure, and a pressure sensor 28 and a throttle valve 29 installed at the inflation end of the main circuit 17. The throttle valve 29 is connected to a hose and then to the quick-connect plug 15. A pneumatic valve No. 2 25 is arranged on branch No. 2 19, and a vacuum pump 26 is arranged behind the pneumatic valve No. 25. A pneumatic valve No. 3 27 is arranged on branch No. 4 21, and a vacuum gauge sensor 32 is arranged behind the pneumatic valve No. 3 27. A safety valve No. 1 31 is arranged behind the vacuum gauge sensor 32. Branch No. 3 20, branch No. 2 19, branch No. 4 21, and branch No. 5 37 converge into an exhaust gas outlet circuit 38, and a one-way valve 33 is arranged on the exhaust gas outlet circuit 38. The exhausted exhaust gas passes through the one-way valve 33 and enters the waste pool. The one-way valve 33 can prevent the exhaust gas in the exhaust pool from entering the gas filling circuit.

[0036] When a certain component gas is filled into a gas cylinder, the pneumatic valve 22 corresponding to the branch 18 where the component gas is located in the gas filling circuit is opened, and the pneumatic valve 22 in the middle of other branches 18 is closed, and the gas cylinder valve is opened, and the component gas enters the gas cylinder through the pressure sensor 28 and the throttle valve 29. The pressure data of the pressure sensor 28 can reflect whether the circuit is being filled and whether the circuit is leaking. The throttle valve 29 can adjust the gas flow rate to facilitate the control of the amount of gas filled. When the component gas filling is completed and another component gas needs to be filled, the pneumatic valve 25 and the pneumatic valve 4 34 must be opened first, and all other pneumatic valves and the gas cylinder valve must be closed. The vacuum pump 26 is turned on to extract the residual component gas in the pipeline. At the same time, the vacuum gauge sensor 32 monitors the exhaust situation. After the vacuum reaches the set value, the vacuum pump 26, the pneumatic valve 25, and the pneumatic valve 4 34 are turned off, and then the next component gas is filled.

[0037] Please refer to the attached Figure 1 - Attachment Figure 3, the loading and unloading subsystem is used for loading and unloading of gas cylinders, which includes a gantry truss manipulator 3 installed on the frame, and a flexible clamping claw 2 36 installed on the execution end of the gantry truss manipulator 3, which is used to transport the gas cylinder from the loading area 1 to the upper part of the electric turntable 5, and to transport the gas cylinder that has been inflated on the upper part of the electric turntable 5 to the unloading area 2, and also includes a barcode scanning camera 4 installed on the outside of the flexible clamping claw 2 36 for identifying the specifications and models of the gas cylinder. After the gas cylinder is clamped by the flexible clamping claw 2 36, the gantry truss manipulator 3 moves the gas cylinder in the three directions of X, Y, and Z, and can move the gas cylinder from the loading area to the inflation station 8, and from the inflation station 8 to the unloading area 2, so as to realize loading and unloading. The barcode scanning camera 4 is installed next to the flexible clamp 2 36. When the gas cylinder is clamped, the barcode scanning camera 4 reads the QR code or barcode on the gas cylinder, which can carry information. The information carried includes the specifications and dimensions of the gas cylinder, the type and filling amount of the component gas to be filled, and sends this information to the industrial computer in the electrical control subsystem. The industrial computer receives the information of the gas cylinder that needs to be filled and records it. Later, it can control the actuators of other subsystems to perform corresponding actions based on this information.

The plug clamp 14 clamps the plug fixed end 151, moves up or down, and moves forward after aligning with the gas nozzle. The quick-connect plug 15 is inserted into the gas nozzle. After the gas distribution is completed, the plug clamp 14 is first clamped on the plug movable sleeve 152, and then lightly pulled backward, and then clamps the plug fixed end 151, and pulls backward to remove the quick-connect plug 15.
