Description

Technical Field

[0001] This invention relates to the field of gas supply manifold technology, specifically a fully automatic switching system for high-pressure gas cylinder supply manifolds. Background Technology

[0002] Gas manifolds are devices designed to improve work efficiency and production safety by centralizing individual gas sources at single gas consumption points and combining multiple gas containers (high-pressure cylinders or cryogenic Dewar flasks, etc.) to achieve centralized gas supply. Manifolds reduce the frequency of cylinder changes, lower labor costs and intensity, while enabling centralized management of high-pressure gases, reducing safety hazards, saving space, and facilitating gas management.

[0003] Most existing gas supply manifold systems on the market consist of high-pressure cylinders on the left and right sides that supply gas alternately. When the gas in one high-pressure cylinder is depleted, the system switches to supply from the other side. However, this method cannot accurately determine the remaining gas content in any individual high-pressure cylinder. Furthermore, because gas is supplied from one side's cylinders simultaneously, the gas in that side's cylinders is usually depleted at the same time, making it impossible to replace individual cylinders. If the gas in one high-pressure cylinder is depleted without timely replacement, it can lead to a gas supply interruption in the manifold system. Additionally, replacing high-pressure cylinders requires manual disassembly and installation, resulting in low automation and high labor costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide a fully automatic switching system for high-pressure gas cylinder manifolds. This system can solve the technical problem of how to avoid gas supply interruptions in the gas supply manifold system and improve the automation level of the gas supply manifold system.

[0005] The objective of this invention is achieved through the following means:

[0006] This is a fully automatic switching system for high-pressure gas cylinder supply manifolds, comprising a conveyor belt, electrical control cabinet, control panel, high-pressure gas cylinders, and an outer casing. The outer casing is located on one side of the conveyor belt, the electrical control cabinet on one side of the outer casing, and the control panel on the side of the electrical control cabinet furthest from the outer casing. The high-pressure gas cylinders are connected to the top of the conveyor belt, and each cylinder has a rotary valve and an outlet pipe. The conveyor belt includes fixed seats, a worktable, a fixed cylinder, and an infrared sensor. The bottom of the high-pressure gas cylinders is connected to the top of the conveyor belt via two or more fixed seats. The worktable is located in the middle of the conveyor belt, and the fixed cylinder and infrared sensor are both located on the top of the worktable. The outer casing has a wired connection. The system includes a linear module, an air tank, a clamping assembly, a ventilation assembly, and an air pipe. The air tank is located on the top of the housing, and an exhaust pipe is located on the top of the air tank. The linear module is located on the inner wall of the housing away from the worktable. The clamping assembly and the ventilation assembly are both connected to the linear module. One end of the air pipe is connected to the air tank, and the other end is connected to the ventilation assembly via a flexible air guide. A first solenoid valve and a pressure sensor are connected to the middle of the air pipe. A sealing joint is screwed onto the outer surface of the exhaust pipe. The conveyor belt, control panel, infrared sensor, linear module, clamping assembly, ventilation assembly, first solenoid valve, and pressure sensor are all electrically connected through an electrical control cabinet.

[0007] In the above description, as a preferred embodiment, the sealing joint consists of a plug, a mounting hole, a limiting rod, a spring, and a sealing block. The mounting hole is located on the side of the plug near the outlet pipe. The limiting rod is installed inside the mounting hole, and the spring is sleeved on the outer surface of the limiting rod. The sealing block is connected to the end of the limiting rod near the outlet pipe, and the sealing joint is screwed onto the outer surface of the outlet pipe. When no gas is supplied, the outlet pipe is sealed to prevent internal gas from flowing out. When gas is supplied, the venting rod pushes open the sealing block, and the gas inside the high-pressure cylinder flows into the gas usage point through the venting rod. After the gas supply is completed, the venting rod is pulled out, and the spring located on the outer surface of the limiting rod drives the sealing block to reset.

[0008] In the above description, as a preferred embodiment, the linear module consists of a motor, a slide rail, and a slider. The slide rail is located on the inner wall of the housing away from the worktable, the motor is connected to one end of the slide rail, and the slider is connected to the slide rail.

[0009] In the above description, as a preferred embodiment, the clamping assembly consists of a first connecting plate and a pneumatic gripper. The first connecting plate is located at one end of the slider, and the pneumatic gripper is connected to the side of the first connecting plate away from the slider.

[0010] In the above description, as a preferred embodiment, the ventilation assembly consists of a second connecting plate, a mounting base, a propulsion cylinder, a connecting elbow, and a ventilation rod. The second connecting plate is located at the end of the slider away from the first connecting plate. The propulsion cylinder is installed on the side of the first connecting plate near the conveyor belt. The mounting base is located on the side of the propulsion cylinder push rod near the pneumatic gripper. The connecting elbow is connected to the mounting base, and the ventilation rod is located on the side of the connecting elbow near the pneumatic gripper.

[0011] In the above description, as a preferred embodiment, a nut is screwed onto the outer surface of the connecting elbow, so that the position of the connecting elbow can be adjusted.

[0012] In the above description, as a preferred embodiment, the end of the exhaust pipe away from the gas storage tank is connected to a one-way valve and a second solenoid valve. The second solenoid valve is electrically connected to the electrical control cabinet to prevent gas backflow, and at the same time, the gas in the gas storage tank can be extracted through the second solenoid valve.

[0013] In the above description, as a preferred embodiment, the mounting base is provided with a sensing strip in the middle, which is electrically connected to the electrical control cabinet. The infrared sensor can locate and mark the mounting base by recognizing the sensing strip. The user can view the mounting base that has been supplied with gas through the control panel, and then replace the high-pressure steel cylinder above the mounting base.

[0014] In the above description, as a preferred embodiment, the outer surface of the sealing joint is provided with a wrench position to facilitate clamping by pneumatic grippers.

[0015] The fully automatic switching system for high-pressure gas cylinder manifolds provided by this invention has the following beneficial effects:

[0016] 1) By providing a fixed seat, workbench, fixed cylinder and infrared sensor on the conveyor belt, the high-pressure steel cylinder can be installed in the fixed seat. The infrared sensor senses the fixed seat and the fixed cylinder fixes the fixed seat, so that the high-pressure steel cylinder can supply gas in a fixed position, while preventing the high-pressure steel cylinder from tipping over during the transmission process.

[0017] 2) The clamping assembly can fix and clamp the sealing joint to ensure that the position of the sealing joint and the venting assembly are on the same axis, preventing the venting assembly from being unable to be accurately inserted into the sealing joint. This allows the venting assembly to connect with the sealing joint. Then, under the action of the first solenoid valve, the gas inside the high-pressure cylinder is delivered to the gas pipe through the gas guide hose, and finally to the gas storage tank. The gas is then delivered to the gas consumption point through the exhaust pipe. At the same time, the pressure sensor can detect the remaining gas in the high-pressure cylinder. When the gas in the high-pressure cylinder is depleted, the next high-pressure cylinder is replaced. This cycle greatly improves the working efficiency and automation of the high-pressure cylinder gas supply manifold, reduces the workload and time cost of manually replacing high-pressure cylinders, and can promptly replace high-pressure cylinders with depleted internal gas to avoid gas supply interruption in the gas supply manifold system.

[0030] The outer casing 5 is provided with a linear module 8, an air tank 501, a clamping assembly 9, a ventilation assembly 10, and an air pipe 11. The air tank 501 is located on the top of the outer casing 5, and an exhaust pipe 502 is provided on the top of the air tank 501. The end of the exhaust pipe 502 away from the air tank 501 is connected to a one-way valve 503 and a second solenoid valve 504. The second solenoid valve 504 is electrically connected to the electrical control cabinet 2 to prevent gas backflow. At the same time, the gas in the air tank 501 can be extracted through the second solenoid valve 504.

[0031] A linear module 8 is located on the inner wall of the outer casing 5 away from the worktable 7. The linear module 8 consists of a motor 801, a slide rail 802, and a slider 803. The slide rail 802 is located on the inner wall of the outer casing 5 away from the worktable 7. The motor 801 is connected to one end of the slide rail 802, and the slider 803 is connected to the slide rail 802. A clamping assembly 9 and a ventilation assembly 10 are both connected to the linear module 8. The clamping assembly 9 consists of a first connecting plate 901 and a pneumatic gripper 902. The first connecting plate 901 is located at one end of the slider 803, and the pneumatic gripper 902 is connected to the first connecting plate 901 on the side away from the slider 803. One end of the air pipe 11 is connected to the air storage tank 501, and the other end is connected to the ventilation assembly 10 via a flexible air guide hose 12. The ventilation assembly 10 consists of a first connecting plate 901, a first connecting plate 901, a second connecting plate 902, and a third connecting plate 902. The system comprises a second connecting plate 1001, a mounting base 1002, a propulsion cylinder 1003, a connecting elbow 1004, and a venting rod 1005. The second connecting plate 1001 is located at the end of the slider 803 away from the first connecting plate 901. The propulsion cylinder 1003 is mounted on the side of the first connecting plate 901 near the conveyor belt 1. The mounting base 1002 is located on the side of the push rod of the propulsion cylinder 1003 near the pneumatic gripper 902. The connecting elbow 1004 is connected to the mounting base 1002. The venting rod 1005 is located on the side of the connecting elbow 1004 near the pneumatic gripper 902. A nut 1006 is screwed onto the outer surface of the connecting elbow 1004 to allow for position adjustment. A first solenoid valve 1101 and a pressure sensor 1102 are connected to the middle of the air pipe 11.

[0032] A sealing joint 13 is screwed onto the outer surface of the vent pipe 402. The sealing joint 13 consists of a plug 1301, a mounting hole 1302, a limiting rod 1303, a spring 1304, and a sealing block 1305. The mounting hole 1302 is located on the side of the plug 1301 near the vent pipe 402. The limiting rod 1303 is installed inside the mounting hole 1302. The spring 1304 is fitted onto the outer surface of the limiting rod 1303. The sealing block 1305 is connected to the end of the limiting rod 1303 near the vent pipe 402. The sealing joint 13 is screwed onto the outer surface of the vent pipe 402 to seal the vent pipe 402 when no gas is supplied, preventing internal gas from flowing out. When supplying gas, the venting rod 1005 pushes open the sealing block 1305, and the gas inside the high-pressure steel cylinder 4 flows into the gas consumption point through the venting rod 1005. After the gas supply is completed, the venting rod 1005 is pulled out, and the spring 1304 on the outer surface of the limit rod 1303 drives the sealing block 1305 to reset. The outer surface of the sealing joint 13 is provided with a wrench position 1306 to facilitate the pneumatic gripper 902 to clamp. The conveyor belt 1, control panel 3, infrared sensor 702, linear module 8, clamping assembly 9, venting assembly 10, first solenoid valve 1101 and air pressure sensor 1102 are all electrically connected through the electrical control cabinet 2.

[0033] Working principle: The operator screws the stopper 1301 onto the outer surface of the vent pipe 402 of the high-pressure cylinder 4, and unscrews the rotary valve 401 of the high-pressure cylinder 4. Under the action of the sealing block 1305 and the stopper 1301, the gas inside the high-pressure cylinder 4 cannot leak out. Then, the high-pressure cylinder 4 is placed on top of the fixed base 6. After all the high-pressure cylinders 4 are placed on top of the fixed base 6, the conveyor belt 1 is started through the control panel 3. The conveyor belt 1 drives the fixed base 6 to move. When the infrared sensor 702 senses the sensing strip 601, the movement stops. When the cylinder 701 extends its push rod to fix the mounting base 6, the slider 803 moves back and forth along the slide rail 802, thereby driving the pneumatic gripper 902 to move above the stopper 1301. The pneumatic gripper 902 then clamps the stopper 1301 at the lever position 1306. The cylinder 1003 then drives the venting rod 1005 to extend, opening the sealing block 1305. Under the action of the first solenoid valve 1101, the gas in the high-pressure cylinder 4 flows through the venting rod 1005 into the connecting elbow 1004. The gas enters the gas storage tank 501 through the gas guide hose 12 and the gas pipe 11, and is finally supplied to the gas consumption point through the exhaust pipe 502 via the second solenoid valve 504. At the same time, under the detection of the pressure sensor 1102, when the gas in the high-pressure cylinder 4 is consumed, the push cylinder 1003 drives the venting rod 1005 to be pulled out from the plug 1301. The sealing block 1305 is reset under the action of the spring 1304 and the limit rod 1303. The pneumatic gripper 902 releases its grip on the plug 1301, and the slider 803 moves along the slide rail. 802 moves to move the pneumatic gripper 902 away from the stopper 1301, avoiding obstruction of the movement of the high-pressure cylinder 4, and then starts the conveyor belt 1 to switch to the next high-pressure cylinder 4. This cycle is repeated to achieve the purpose of fully automatic switching of the gas supply manifold of the high-pressure cylinder 4. This can greatly improve the working efficiency and automation of the gas supply manifold of the high-pressure cylinder 4, reduce the workload and time cost of manually replacing the high-pressure cylinder 4, and at the same time, it can replace the high-pressure cylinder 4 with depleted internal gas in time to avoid the gas supply manifold system from being interrupted.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the inventive concept, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
