Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner production and processing, specifically to an automatic inflation docking device. Background Technology

[0002] An air conditioner, or air conditioner, is a device that artificially regulates and controls parameters such as temperature, humidity, and airflow within a building or structure. An air conditioning system typically consists of a cold / heat source, a cold / heat medium distribution system, terminal units, and other auxiliary equipment, primarily including a refrigeration unit, water pump, fan, and piping system. The terminal units are responsible for utilizing the distributed cooling or heating energy to specifically regulate the air conditions, ensuring that the air parameters of the target environment meet predetermined requirements.

[0003] Currently, most split-type air conditioners on the market use copper pipes for their intake and exhaust pipes. During the air conditioner manufacturing process, the weld joints of the copper pipes are prone to oxidation when exposed to oxygen in the air, producing oxide scale that can clog the piping system and affect the overall performance of the unit. To solve this problem, the piping needs to be purged with nitrogen for protection before welding.

[0004] In existing technologies, nitrogen purging largely relies on manual operation. Specifically, the operator first connects the intake and exhaust pipes, then uses a nitrogen purging fixture with a pre-connected nitrogen pipeline to connect to the machine. Different nitrogen purging fixtures are selected depending on the connection point (valve or process pipe). The fixture is equipped with a spring-loaded sensor that automatically turns on the nitrogen after connection. After purging for the specified time, the operator disassembles the fixture to complete the nitrogen purging process.

[0005] However, manual nitrogen filling is not only time-consuming and labor-intensive, but also carries the risk of incomplete or false nitrogen filling. It is also greatly affected by human factors, making it difficult to guarantee the quality of nitrogen filling. Although automatic nitrogen filling can replace manual operation, the complex docking method makes it difficult to implement, and the docking status cannot be monitored in real time. This may lead to nitrogen filling failure and the process proceeding directly to the welding step.

[0006] Therefore, existing technologies still need further development. Utility Model Content

[0007] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an automatic gas-filling docking device to solve the technical problem that the existing nitrogen-filling equipment cannot monitor the docking status in real time, which may lead to nitrogen-filling failure and direct entry into the welding process.

[0008] To achieve the above-mentioned technical objectives, according to one aspect of this utility model: an automatic inflation docking device is provided, comprising: a docking component, an elastic buffer component, and a detection component. The docking component is used to dock with the connection part of the device to be inflated. The elastic buffer component is movably disposed and has a conveying part and a fixing part. The input end of the conveying part is used to connect to a gas source, and the output end of the conveying part is connected to the docking component. The fixing part is sleeved on the conveying part, and the conveying part is movably disposed relative to the fixing part along a preset direction, so that when the docking component docks with the connection part of the device to be inflated, the conveying part moves relative to the fixing part. The detection component is used to detect the displacement of the conveying part relative to the fixing part in a direction away from the docking component along the preset direction, and to determine the docking state of the docking component and the device to be inflated based on the detected displacement.

[0009] Furthermore, the automatic inflation docking device also includes: a first support, the first support having a first support and a second support connected to each other, the first support and the second support forming a first preset angle, the first preset angle being greater than 0° and less than or equal to 90°; the first support being fixedly connected to the fixing part, the end of the second support away from the first support being arranged in a direction away from the docking component, and the second support being arranged parallel to the conveying part; the detection component being adjustablely arranged on the second support along a preset direction, so as to adjust the position of the detection component relative to the second support and the position of the detection component relative to the conveying part.

[0010] Furthermore, the elastic buffer assembly includes: a conduit extending in a preset direction to form a delivery section; and a fixing tube extending in a preset direction, sleeved on the conduit to form a fixing section; wherein the conduit includes a conduit body and a first limiting portion, the first limiting portion being located at the input end of the conduit body, and the first limiting portion being used to abut against the end of the fixing tube away from the docking assembly.

[0011] Furthermore, the elastic buffer assembly also includes: a limiting member, which is sleeved on the conduit body and located at one end of the conduit body near the docking assembly, and the limiting member is fixedly connected to the conduit body; and an elastic member, which is sleeved on the conduit body, with its two ends abutting against the fixed tube and the limiting member, respectively. When the docking assembly and the connection portion of the device to be inflated are subjected to pressure, the conduit moves relative to the fixed tube in a preset direction away from the docking assembly, so that the elastic member is in a compressed state. When the docking pressure between the docking assembly and the connection portion of the device to be inflated decreases, the elastic member is in a restoring state, thereby pushing the conduit relative to the fixed tube in a preset direction towards the docking assembly.

[0012] Furthermore, the automatic inflatable docking device also includes: a moving mechanism, the connecting end of which is movably disposed, the connecting end of which is connected to an elastic buffer component, and the moving mechanism drives the docking component to move through the elastic buffer component.

[0013] Furthermore, the automatic inflation docking device also includes: a second support, the second support having a third support and a fourth support connected to each other, the third support and the fourth support forming a second preset angle, the second preset angle being greater than or equal to 0° and less than or equal to 180°; the third support being connected to the connecting end of the moving mechanism, and the fourth support being fixedly connected to the fixed tube; wherein, the angle of the third support relative to the moving mechanism is adjustable.

[0014] Furthermore, the third support is provided with a connecting hole and an arc-shaped through hole. The connecting hole is used to pre-fix the third support to the moving mechanism. The arc-shaped through hole is spaced apart from the connecting hole so that after the third support is adjusted at its angle relative to the moving mechanism, the arc-shaped through hole is used to fix the third support to the moving mechanism.

[0015] Furthermore, the fourth support has a through hole extending in a preset direction; the fixing tube is inserted through the through hole into the fourth support; the outer wall of the fixing tube has an external thread; the automatic inflation docking device also includes: two connecting nuts, which are threaded into the external thread of the fixing tube; the two connecting nuts are spaced apart on the fixing tube along its extension direction, and are located on both sides of the fourth support, and the fixing tube is fixedly connected to the fourth support through the two connecting nuts; wherein, when the displacement detected by the detection component is greater than or equal to the preset compression value of the elastic element, the position of the fixing tube relative to the fourth support is adjusted by adjusting the position of the two connecting nuts relative to the fixing tube.

[0016] Furthermore, the automatic inflation docking device also includes: a mounting plate, which is fixedly connected to the connecting end of the moving mechanism; a third support mounted on the side of the mounting plate away from the connecting end of the moving mechanism; and an elastic buffer assembly connected to the connecting end of the moving mechanism via a second bracket and the mounting plate.

[0017] Furthermore, the docking assembly includes: a washer movably connected to the output end of the conveying unit; and a mating joint fixedly connected to the end of the washer away from the output end of the conveying unit, the mating joint being used to connect to the connection part of the device to be inflated; wherein the mating surface inside the mating joint is a conical surface.

[0018] Beneficial effects:

[0019] Applying the technical solution of this utility model, an automatic inflation docking device is provided, comprising a docking component, an elastic buffer component, and a detection component. The docking component is used to dock with the connection part of the device to be inflated, facilitating the inflation operation of the device.

[0020] The elastic buffer assembly includes a fixing part and a conveying part. The fixing part is sleeved on the conveying part, and the conveying part can move relative to the fixing part in a preset direction. The input end of the conveying part is used to connect to a gas source, and its output end is connected to a docking assembly. Thus, after the docking assembly completes docking with the connection part of the device to be inflated, the gas output from the gas source can be sequentially conveyed to the device to be inflated through the conveying part and the docking assembly.

[0021] In addition, the detection component is used to detect the amount of displacement of the conveying part relative to the fixed part in a preset direction away from the docking component during the docking process, and to determine the docking status between the docking component and the device to be inflated based on the amount of displacement.

[0022] Therefore, by setting up the docking component, rapid and precise docking with the connection part of the device to be inflated can be achieved, significantly reducing the time and effort required for manual alignment and improving docking efficiency. At the same time, the excellent fit between the docking component and the connection part ensures smooth gas transmission, effectively preventing gas leakage and guaranteeing high efficiency and stability in the inflation process. Furthermore, the precise docking method also reduces the risk of gas leakage due to poor docking and avoids the problem of direct welding due to nitrogen filling failure.

[0023] Furthermore, the fixing part in the elastic buffer assembly is sleeved on the outside of the conveying part, and the conveying part has the ability to reciprocate relative to the fixing part in a preset direction. When the docking assembly contacts the connection part of the device to be inflated and docking pressure is applied, this structural design allows the conveying part to adjust its position within a certain range, thereby avoiding rigid contact between the docking assembly and the connection part and playing a buffering and protective role. This not only extends the service life of the docking assembly and the device to be inflated, but also effectively ensures the stability and sealing of the connection between the two.

[0024] Furthermore, by incorporating a detection component, the displacement of the conveyor relative to the stationary part along a preset direction away from the docking component can be monitored in real time during the docking process. This allows for rapid determination of whether the docking component has achieved a proper docking with the equipment to be inflated. If an abnormal displacement is detected, the detection component can promptly issue an early warning signal to alert the operator. Precise detection of displacement ensures that the docking component remains in the correct docking state. This precise monitoring mechanism overcomes the shortcomings of traditional manual judgment methods, improving the reliability and intelligence of the entire docking process. Simultaneously, the displacement detection function of the detection component provides operators with clear docking status information, eliminating the need for frequent manual checks on docking success and simplifying the operational process.

[0025] In summary, the automatic inflatable docking device provided by this utility model achieves automation and intelligence in the docking process through the synergistic effect of the docking components, elastic buffer components, and detection components. It not only effectively reduces the labor intensity of manual assembly processes and improves nitrogen filling quality and inflatable efficiency, but also solves the technical problem in the prior art where nitrogen filling equipment cannot monitor the docking status in real time, which may lead to nitrogen filling failure and direct welding.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] Air conditioners, as an indispensable piece of equipment in modern life, require a nitrogen-purging protection process during the welding of copper pipes in their internal system structure. This process involves filling the copper pipes with nitrogen gas to replace the original air, thereby reducing the oxide scale that forms on the inner wall of the copper pipes due to oxidation during the high-temperature welding process. If effective nitrogen purging protection is not performed, a large amount of oxides will be generated inside the copper pipes. This oxide scale is easily detached and remains in the pipes, causing blockages in critical components of the air conditioner's main compressor system, such as the evaporator and condenser, leading to a series of quality problems such as abnormal exhaust temperature, compressor seizure, and failure of cooling / heating functions.

[0034] Currently, in the air conditioner production process, key components such as four-way valves typically require manual piping. During the nitrogen purging process before welding, operators must use handheld nitrogen purging equipment to purge the copper pipes. The specific procedure is as follows: first, the intake and exhaust pipes are piped; then, workers manually align the nitrogen pipeline or nozzle with the air conditioner shut-off valve port to purge with nitrogen; after the specified time has elapsed, the nitrogen source is disconnected from the shut-off valve, and finally, welding is performed.

[0035] However, since air conditioning systems typically include two shut-off valves—an exhaust shut-off valve (low-pressure valve) and an intake shut-off valve (high-pressure valve)—in actual production processes, one operator often needs to simultaneously assemble two sets of pipes and perform nitrogen purging on both valves. This manual nitrogen purging method is not only labor-intensive and inefficient, but also poses significant quality risks, such as frequent issues like missed purging and false purging, resulting in an inability to effectively guarantee the nitrogen purging effect.

[0036] Although existing technologies have proposed some automatic nitrogen-filling docking devices to address the above problems, these devices generally suffer from complex docking structures, high control difficulty, and a lack of real-time monitoring of docking status. This means that docking failures or insufficient nitrogen filling may still occur in practical applications, and operators may fail to detect these issues in time. Ultimately, this can lead to welding being performed directly without sufficient nitrogen filling, creating potential risks for system malfunction.

[0037] To address the aforementioned technical deficiencies, this embodiment provides an automatic nitrogen filling and docking device, which aims to solve the technical problem that existing nitrogen filling equipment cannot monitor the docking status in real time, which may lead to nitrogen filling failure and direct entry into the welding process, thereby improving the automation level, reliability, and safety of the nitrogen filling process.

[0038] Please see Figures 1 to 4 According to an embodiment of the present invention, an automatic inflation docking device is provided, comprising: a docking component 1, an elastic buffer component 2, and a detection component. The docking component 1 is used to dock with the connection part of the device to be inflated. The elastic buffer component 2 is movably disposed and has a conveying part and a fixing part. The input end of the conveying part is used to connect to a gas source, and the output end of the conveying part is connected to the docking component 1. The fixing part is sleeved on the conveying part, and the conveying part is movably disposed relative to the fixing part in a preset direction so that when the docking component 1 docks with the connection part of the device to be inflated, the conveying part moves relative to the fixing part. The detection component is used to detect the displacement of the conveying part relative to the fixing part in a preset direction away from the docking component 1, and to determine the docking state of the docking component 1 and the device to be inflated based on the detected displacement.

[0039] As can be seen, the automatic inflation docking device provided by this utility model includes a docking component 1, an elastic buffer component 2, and a detection component. The docking component 1 is used to dock with the connection part of the device to be inflated, so as to facilitate the inflation operation of the device.

[0040] The elastic buffer assembly 2 includes a fixing part and a conveying part. The fixing part is sleeved on the conveying part, and the conveying part can move relative to the fixing part in a preset direction. The input end of the conveying part is used to connect to a gas source, and its output end is connected to the docking assembly 1. Thus, after the docking assembly 1 completes docking with the connection part of the device to be inflated, the gas output from the gas source can be conveyed to the device to be inflated in sequence through the conveying part and the docking assembly 1.

[0041] In addition, the detection component is used to detect the amount of displacement of the conveying part relative to the fixed part in a preset direction away from the docking component 1 during the docking process, and to determine the docking status between the docking component 1 and the device to be inflated based on the amount of displacement.

[0042] Therefore, by setting up the docking component 1, rapid and precise docking with the connection part of the device to be inflated can be achieved, significantly reducing the time and effort required for manual alignment and improving docking efficiency. Simultaneously, the excellent fit between the docking component 1 and the connection part ensures smooth gas transmission, effectively preventing gas leakage and guaranteeing high efficiency and stability during the inflation process. Furthermore, the precise docking method reduces the risk of gas leakage due to poor docking and avoids the problem of direct welding due to potential nitrogen filling failure.

[0043] Furthermore, the fixing part of the elastic buffer assembly 2 is sleeved on the outside of the conveying part, and the conveying part has the ability to reciprocate relative to the fixing part in a preset direction. When the docking assembly 1 contacts the connecting part of the device to be inflated and docking pressure is applied, this structural design allows the conveying part to adjust its position within a certain range, thereby avoiding rigid contact between the docking assembly 1 and the connecting part and playing a buffering and protective role. This not only extends the service life of the docking assembly and the device to be inflated, but also effectively ensures the stability and sealing of the connection between the two.

[0044] Furthermore, by incorporating a detection component, the displacement of the conveying unit relative to the fixed unit along a preset direction away from the docking component 1 can be monitored in real time during the docking process. This allows for rapid determination of whether the docking component 1 has achieved a proper docking with the equipment to be inflated. If an abnormal displacement is detected, the detection component can promptly issue a warning signal to alert the operator. Precise detection of displacement ensures that the docking component 1 remains in the correct docking state. This precise monitoring mechanism overcomes the shortcomings of traditional manual judgment methods, improving the reliability and intelligence of the entire docking process. Simultaneously, the displacement detection function of the detection component provides operators with clear docking status information, eliminating the need for frequent manual checks on docking success and simplifying the operational process.

[0045] In summary, the automatic inflatable docking device provided by this utility model achieves automation and intelligence in the docking process through the synergistic effect of docking component 1, elastic buffer component 2, and detection component. It not only effectively reduces the labor intensity of manual assembly processes and improves nitrogen filling quality and inflatable efficiency, but also solves the technical problem in the prior art where nitrogen filling equipment cannot monitor the docking status in real time, which may lead to nitrogen filling failure and direct welding.

[0046] The device to be inflated is an air conditioner, and the connection part of the device to be inflated is the shut-off valve or other welded pipe of the air conditioner.

[0047] Furthermore, when docking component 1 docks with the connecting part of the device to be inflated, a certain docking pressure is generated. At this time, under the action of this docking pressure, the conveying part in the elastic buffer component 2 will move away from the docking component 1 in a preset direction relative to the fixed part; when the docking pressure decreases, the conveying part will move in the opposite direction, that is, move towards the docking component 1, thereby pushing the docking component 1 to fit more tightly with the connecting part of the device to be inflated, ensuring good sealing between the two and providing reliable protection for the subsequent inflation process.

[0048] Furthermore, in the elastic buffer assembly 2, when the conveying part of the elastic buffer assembly 2 is subjected to docking pressure and is displaced relative to the fixing part of the elastic buffer assembly 2 in a preset direction away from the docking assembly 1, the detection assembly will detect the current displacement in real time and compare the detected displacement value with the preset displacement range to determine whether the docking state is normal.

[0049] If the detected displacement is outside the preset displacement range, an alarm function will be triggered to remind the operator to check the docking status in time to prevent gas leakage or inflation failure due to poor docking.

[0050] The preset displacement range is greater than 0 and less than or equal to 50% of the maximum preset displacement threshold allowed by the conveying unit. Specifically:

[0051] If the displacement measured by the detection device is 0, it means that the docking component 1 has not yet formed an effective docking with the connection part of the equipment to be inflated.

[0052] If the detected displacement exceeds 50% of the preset displacement threshold of the conveying unit, it indicates a risk of overpressure docking, which may cause damage to the docking components or connection parts.

[0053] If the detected displacement is within the preset displacement range, proceed to the next step.

[0054] Therefore, when the detection result shows that the displacement is equal to 0 or exceeds 50% of the preset displacement threshold of the conveying unit, the detection component will automatically issue an alarm signal to prompt the operator to perform inspection and necessary maintenance, thereby improving the safety and reliability of the entire inflation docking process.

[0055] Furthermore, nitrogen is preferred as the inflation gas. Using nitrogen for inflation helps to remove air from the system, prevents oxidation and contamination by impurities, improves inflation quality, and meets the technical requirements for inflation of high-precision equipment.

[0056] Furthermore, the conveying section in the elastic buffer assembly 2 has a conveying channel, and an input port and an output port connected to the conveying channel. The docking assembly 1 is provided with a guide channel connected to the output port. The conveying channel extends in a preset direction, and the input port of the conveying section forms the input end of the conveying section, and the output port of the conveying section forms the output end of the conveying section.

[0057] Specifically, the output end of the conveying section of the elastic buffer assembly 2 is connected to the input end of the docking assembly 1; the output end of the docking assembly 1 is used to connect to the connecting section of the device to be inflated.

[0058] Specifically, the detection component is located above the input end of the conveying section of the elastic buffer component 2.

[0059] Preferably, the detection component is a metal sensor.

[0060] Specifically, such as Figure 1 and Figure 2 As shown, the automatic inflation docking device further includes: a first support 3, the first support 3 having a first support 31 and a second support 32 connected to each other, the first support 31 and the second support 32 being connected and forming a first preset angle, the first preset angle being greater than 0° and less than or equal to 90°; the first support 31 being fixedly connected to the fixing part, the end of the second support 32 away from the first support 31 being arranged in a direction away from the docking assembly 1, and the second support 32 being arranged parallel to the conveying part; the detection assembly being adjustablely arranged on the second support 32 along a preset direction, so as to adjust the position of the detection assembly relative to the second support 32 and the position of the detection assembly relative to the conveying part.

[0061] With this structural arrangement, the second support 32 is positioned parallel to the conveying unit, and the detection component is adjustablely mounted on the second support 32 along a preset direction. This design allows the detection component to maintain a relatively stable distance and positional relationship with the conveying unit, thereby improving the accuracy of the detection component's detection of the conveying unit's displacement. Since the displacement of the conveying unit is a key parameter for judging the docking status, accurate detection results can more reliably reflect the docking status between the docking component and the equipment to be inflated, avoiding misjudgments caused by detection errors. At the same time, the adjustable position of the detection component provides great convenience for actual operation. During installation and commissioning, the position of the detection component can be flexibly adjusted according to specific working requirements and the characteristics of the equipment to be inflated to achieve the best detection effect.

[0062] Furthermore, the first support 31 and the second support 32 form a first preset angle, which is greater than 0° and less than or equal to 90°. This allows the first support 3 to adapt to the spatial layout and installation requirements of different devices to be inflated, while also ensuring that the second support 32 can be set parallel to the conveying unit. This design not only improves the flexibility and applicability of the device but also provides conditions for the accurate installation and operation of the detection components, thereby ensuring the reliable operation of the entire automatic inflation docking device.

[0063] The second support 32 and the conveying section both extend in a preset direction.

[0064] Preferably, the first preset included angle is 90°, that is, the first support 31 and the second support 32 are in a perpendicular state.

[0065] The first support 31 and the second support 32 are connected by welding or integral molding.

[0066] Furthermore, such as Figure 1As shown, an adjustment hole 320 is provided on the second support 32. The adjustment hole 320 extends in a preset direction. At least a portion of the detection component is adjustablely disposed in the second support 32 in the preset direction so as to adjust the position of the detection component relative to the adjustment hole 320 and the position of the detection component relative to the conveying part.

[0067] This structural design allows for optimal positioning of the detection component and the conveying unit by adjusting the position of the detection component within the adjustment hole 320. This improves the accuracy of the detection component's measurement of the conveying unit's displacement. In practical applications, the displacement of the conveying unit is a key parameter for determining the docking status. Accurate detection results more reliably reflect the docking status between the docking component and the equipment to be inflated, avoiding misjudgments caused by detection errors. Furthermore, the adjustment hole 320 provides a wide adjustment range when adjusting the position of the detection component based on the position of the conveying unit, making it easier for installers to place the detection component in the appropriate position.

[0068] Specifically, such as Figure 2 As shown, the elastic buffer assembly 2 includes: a conduit 21 and a fixing tube 22. The conduit 21 extends in a preset direction to form a delivery section; the fixing tube 22 extends in a preset direction and is sleeved on the conduit 21 to form a fixing section; wherein, the conduit 21 includes a conduit body 211 and a first limiting part 212. The first limiting part 212 is located at the input end of the conduit body 211 and is used to abut against the end of the fixing tube 22 away from the docking assembly 1.

[0069] With this structural design, the conduit 21 can slide relative to the fixed tube 22, allowing the docking assembly 1 to maintain good docking performance when facing equipment to be inflated at different installation positions or angles, thus improving the adaptability and reliability of the device. Specifically, when docking pressure occurs between the docking assembly 1 and the connection part of the equipment to be inflated, the conduit 21 can move inside the fixed tube 22 in a preset direction, thereby absorbing impact energy and providing necessary buffer protection.

[0070] In addition, a first limiting part 212 is provided at the input end of the catheter body 211 to limit the relative position between the catheter 21 and the fixing tube 22, especially when the docking pressure is released or reduced. The first limiting part 212 ensures that the catheter 21 will not disengage from the fixing tube 22 due to excessive displacement.

[0071] Preferably, the first limiting part 212 is sleeved on the catheter body 211, and the first limiting part 212 is fixedly connected to the catheter body 211. The width of the first limiting part 212 is greater than the inner diameter of the fixed tube 22.

[0072] Specifically, such as Figure 1and Figure 2 As shown, the elastic buffer assembly 2 further includes: a limiting member 23 and an elastic member. The limiting member 23 is sleeved on the conduit body 211 and is located at one end of the conduit body 211 near the docking assembly 1. The limiting member 23 is fixedly connected to the conduit body 211. The elastic member is sleeved on the conduit body 211, and its two ends abut against the fixed tube 22 and the limiting member 23, respectively. When the docking assembly 1 and the connection part of the device to be inflated are subjected to pressure, the conduit 21 moves relative to the fixed tube 22 in a preset direction away from the docking assembly 1, so that the elastic member is in a compressed state. When the docking pressure between the docking assembly 1 and the connection part of the device to be inflated decreases, the elastic member is in a restoring state, so as to push the conduit 21 relative to the fixed tube 22 in a preset direction toward the docking assembly 1.

[0073] With this structural design, an elastic element is incorporated, which generates elastic force to move the conduit 21 relative to the fixed tube 22 along a preset direction. This elastic force not only effectively absorbs and buffers pressure shocks during docking but also prevents damage to the connection between the docking assembly 1 and the equipment to be inflated due to excessive instantaneous pressure, thereby improving the overall structural stability and service life.

[0074] Meanwhile, during the docking process, the elastic element can automatically adjust the relative position between the conduit body 211 and the fixed tube 22 to ensure that the docking assembly 1 and the connection part of the equipment to be inflated always maintain a tight fit, thus ensuring the sealing and reliability of the gas transmission process.

[0075] In addition, the limiting component 23 is used to position and limit the elastic component, preventing it from shifting or falling off during operation, thereby ensuring that the elastic component is always in the set working state, further improving the stability and safety of the entire elastic buffer assembly 2.

[0076] The working principle of the elastic element in the automatic inflation docking device is based on its own elastic properties; that is, the elastic element can deform when subjected to external force and return to its original shape after the external force is removed. The specific working principle of the elastic element in this device is as follows:

[0077] When docking component 1 aligns with the connection part of the device to be inflated, a certain docking pressure is generated. At this time, the conduit 21 is subjected to pressure and moves away from docking component 1 along a preset direction. During this process, the elastic element is compressed, undergoes elastic deformation, and stores elastic potential energy. Through elastic deformation, the elastic element can absorb and buffer external forces, thereby reducing the impact on the conduit 21 and the fixed tube 22, as well as the impact on the connection part of docking component 1 and the device to be inflated, while preventing damage to components due to excessive external forces.

[0078] When the docking pressure between the docking component 1 and the connection between the device to be inflated decreases, the elastic element is no longer subjected to external force, and the elastic potential energy stored inside it begins to be released. At this time, the elastic element extends through its own restoring force, thereby causing the conduit 21 to move towards the docking component 1 along a preset direction, thus ensuring that the docking component 1 and the connection between the device to be inflated always maintain a tight fit, ensuring the sealing and reliability of the gas transmission process.

[0079] Under the action of the docking pressure, the conveying part in the elastic buffer assembly 2 will move away from the docking assembly 1 in a preset direction relative to the fixed part; when the docking pressure decreases, the conveying part will move in the opposite direction, that is, move towards the docking assembly 1, thereby pushing the docking assembly 1 to fit more tightly against the connection part of the device to be inflated, ensuring good sealing between the two and providing reliable protection for the subsequent inflation process.

[0080] Preferably, the elastic element is a spring.

[0081] Specifically, the automatic inflation docking device also includes: a moving mechanism, the connecting end of which is movably set and connected to the elastic buffer component 2, the moving mechanism driving the docking component 1 to move through the elastic buffer component 2.

[0082] This structural design, through the inclusion of a moving mechanism that works in conjunction with the elastic buffer assembly and docking assembly, enables the automatic nitrogen filling docking device to achieve fully automated operation of the nitrogen filling docking process. The moving mechanism can drive the docking assembly to precisely move to the connection point of the equipment to be filled, based on a preset path or external control signal, completing the automatic docking action. This completely replaces the traditional method of relying on manual handheld nitrogen filling equipment for alignment and filling.

[0083] Preferably, the moving mechanism is a robot. The robot moves the docking component 1 to the connection part of the device to be inflated for inflation docking. After docking is completed, inflation is performed. After inflation is completed, the robot moves the docking component 1 away from the connection part of the device to be inflated. Compared with manual inflation, using a robotic arm for automated inflation improves inflation efficiency and reduces the labor intensity of workers.

[0084] Specifically, such as Figures 1 to 4 As shown, the automatic inflation docking device further includes: a second support 4, the second support 4 having a third support 41 and a fourth support 42 connected to each other, the third support 41 and the fourth support 42 forming a second preset angle, the second preset angle being greater than or equal to 0° and less than or equal to 180°; the third support 41 is connected to the connecting end of the moving mechanism, and the fourth support 42 is fixedly connected to the fixed tube 22; wherein, the angle of the third support 41 relative to the moving mechanism is adjustable.

[0085] With the above-described structure, the second bracket 4 allows the elastic buffer assembly 2 and the docking assembly 1 to be securely mounted on the moving mechanism, thereby automating the entire inflation docking process. The second bracket 4 includes a third support 41 and a fourth support 42 connected to each other, forming a second preset angle between them. This angle is greater than or equal to 0° and less than or equal to 180°, allowing for the selection of the appropriate angle for the second bracket 4 based on the spatial layout and installation requirements of different inflatable devices. This design enables the entire automatic inflation docking device to flexibly adapt to various angles and spatial arrangements of the connection ports of inflatable devices, significantly improving the compatibility and versatility of the device in various application scenarios.

[0086] Meanwhile, the angle of the third support 41 relative to the moving mechanism is adjustable, allowing the docking component 1 to complete the docking operation at the optimal angle by adjusting the posture of the second support 4 when facing connection ports with different docking angles. This structure not only improves docking accuracy but also effectively avoids problems such as poor docking and inadequate sealing caused by angle deviations, further ensuring the stability and reliability of the nitrogen filling process, and further improving the applicability of the automatic gas filling docking device, enhancing its adaptability to complex working conditions.

[0087] The angle between the third support 41 and the fourth support 42 can be designed as an obtuse angle, an acute angle, or 90° or 180° to facilitate inflation.

[0088] Preferably, the angle between the third support 41 and the fourth support 42 is 90°. That is, the second support 4 is an L-shaped support.

[0089] Furthermore, the third support 41 and the fourth support 42 are connected by welding or integral molding.

[0090] Furthermore, such as Figures 1 to 4 As shown, the third support 41 is provided with a connecting hole 410 and an arc-shaped through hole 411. The connecting hole 410 is used to pre-fix the third support 41 onto the moving mechanism. The arc-shaped through hole 411 is spaced apart from the connecting hole 410 so that after the third support 41 has been adjusted at its angle relative to the moving mechanism, the arc-shaped through hole 411 is used to fix the third support 41 onto the moving mechanism.

[0091] With this structural design, by combining the connecting hole 410 and the arc-shaped through hole 411, when adjusting the angle of the third support 41 relative to the moving mechanism, it can be initially fixed through the connecting hole 410, and then the angle can be finely adjusted and finally locked through the arc-shaped through hole 411, thus taking into account both adjustment flexibility and positioning stability.

[0092] Meanwhile, the arc-shaped through-hole 411 allows for free adjustment of the second bracket 4's posture within a certain angle range, enabling alignment without repeated disassembly and reassembly. This simplifies the assembly process and improves installation efficiency and ease of operation. Furthermore, after angle adjustment and locking, the arc-shaped through-hole 411, in conjunction with fasteners, ensures the third support 41 is firmly fixed, preventing angular displacement due to vibration or external forces. This ensures that the docking assembly 1 always completes docking in the optimal posture, improving docking accuracy and sealing reliability.

[0093] In summary, this structural design enables the automatic inflation docking device to adapt to inflatable equipment with different spatial layouts and installation angles, significantly enhancing the applicability and on-site adaptability of the equipment and improving the versatility of the overall tooling system.

[0094] Specifically, such as Figure 2 As shown, the fourth support 42 has a through hole extending in a preset direction; the fixing tube 22 is inserted through the through hole onto the fourth support 42; the outer wall of the fixing tube 22 has an external thread; the automatic inflation docking device also includes: two connecting nuts 5, which are threadedly engaged with the external thread of the fixing tube 22; the two connecting nuts 5 are spaced apart on the fixing tube 22 along the extension direction of the fixing tube 22, and the two connecting nuts 5 are respectively located on both sides of the fourth support 42, and the fixing tube 22 is fixedly connected to the fourth support 42 through the two connecting nuts 5; wherein, when the displacement detected by the detection component is greater than or equal to the preset compression value of the elastic element, the position of the fixing tube 22 relative to the fourth support 42 is adjusted by adjusting the position of the two connecting nuts 5 relative to the fixing tube 22.

[0095] This structural design, using external threads on the outer wall of the fixed tube 22 and securing it with two connecting nuts 5, ensures a firm connection between the fixed tube 22 and the fourth support 42 while allowing for fine-tuning as needed, ensuring the entire system operates at its optimal state. Furthermore, the design of the two connecting nuts 5 allows the fixed tube 22 to achieve precise positioning through simple tightening and maintains a stable connection under different operating conditions, preventing positional shifts caused by vibration or other external factors.

[0096] At the same time, the connection nut 5 not only facilitates installation and disassembly, but also supports quick adjustments based on test results during equipment operation, without the need for complex tools or long downtime, greatly improving maintenance efficiency and equipment operability.

[0097] Furthermore, when the detection component detects a displacement exceeding the preset range, the position of the fixing tube 22 can be recalibrated by adjusting the connecting nut 5, ensuring the system is always in optimal working condition. This enhances the adaptability of the entire automatic inflation docking device to different working conditions and ensures that the docking component 1 and the connection point of the equipment to be inflated make elastic, soft contact. Therefore, accurate positioning and stable fixing help improve the alignment accuracy between the docking component 1 and the connection port of the equipment to be inflated, avoiding poor sealing or gas leakage caused by positional deviations, and further improving the quality and reliability of the nitrogen filling process.

[0098] When the detection component detects that the displacement of the conduit 21 is greater than or equal to the preset compression value of the elastic element, the system will automatically trigger an alarm signal, prompting the operator that the current docking status is abnormal and that the position of the fixed tube 22 relative to the second support 4 needs to be adjusted accordingly. The specific operating steps are as follows:

[0099] First, the operator rotates the two connecting nuts 5 to move them away from each other along the extension direction of the fixed tube 22, thereby releasing the clamping effect on the fourth support 42.

[0100] Subsequently, the fixing tube 22 is moved along the preset direction toward the side away from the docking component 1 to adjust its relative position on the second bracket 4; finally, the two connecting nuts 5 are tightened again to lock them onto both sides of the fourth support 42, thereby firmly fixing the fixing tube 22 back into the adjusted position.

[0101] Specifically, such as Figure 1 As shown, the automatic inflation docking device also includes: a mounting plate 6, which is fixedly connected to the connecting end of the moving mechanism; a third support 41 is installed on the side of the mounting plate 6 away from the connecting end of the moving mechanism; and an elastic buffer assembly 2 is connected to the connecting end of the moving mechanism via a second bracket 4 and the mounting plate 6.

[0102] With this structural design, the mounting plate 6 serves as an intermediate connecting component, effectively integrating the moving mechanism, the second support 4, and the elastic buffer assembly 2 together. This enhances the connection strength and structural rigidity between the components and improves the overall stability of the device operation.

[0103] Specifically, such as Figure 1 , Figure 3 As shown, the docking assembly 1 includes: a washer 11 and a connector 12. The washer 11 is movably connected to the output end of the conveying section; the connector 12 is fixedly connected to the end of the washer 11 away from the output end of the conveying section, and the connector 12 is used to connect to the connection part of the device to be inflated; wherein, the mating surface inside the connector 12 is a conical surface.

[0104] This structural design, with the movable connection between the gasket 11 and the output end of the conveying unit, allows the conveying unit to be angled according to the actual docking position, enhancing the device's adaptability to different installation environments and interface directions. The connector 12 features a tapered docking surface design, which automatically matches the interface angle of the equipment to be inflated, ensuring good sealing contact, preventing gas leakage, and guaranteeing inflation quality.

[0105] Furthermore, the conveying section has a symmetrical structure with a central line of symmetry. The angle between the central line of symmetry of the conveying section and the central axis of the washer 11 is adjustable, meaning that the central line of symmetry of the conveying section and the central axis of the washer 11 can coincide, so that the conveying section and the washer 11 are on the same straight line. Alternatively, the central line of symmetry of the conveying section can be deflected at a certain angle relative to the central axis of the washer 11, so that an angle can be formed between the central axes of the conveying section and the washer 11.

[0106] Furthermore, the washer 11 has a receiving cavity. The docking assembly 1 also includes a rotating member, which is rotatably disposed within the receiving cavity, and the output end of the conveying section is connected to the rotating member. The rotating member has a gas passage, which is connected to the flow passage of the docking connector 12 and the conveying passage of the conveying section, respectively, and the conveying section is movably connected to the washer 11 via the rotating member.

[0107] The rotating component is a rotating ball.

[0108] Preferably, such as Figure 1 As shown, there are two of each of the following components: docking component 1, elastic buffer component 2, first bracket 3, and second bracket 4. Each docking component 1 is respectively configured to correspond one-to-one with each elastic buffer component 2, each first bracket 3, and each second bracket 4. The second brackets 4 are spaced apart on the mounting plate 6.

[0109] Preferably, the assembly process of the automatic inflation docking device is as follows:

[0110] 1. Mounting plate installation

[0111] Mounting plate 6 is fixed to the robot (mobile mechanism) as the base for subsequent component installation.

[0112] 2. Pre-fixing and angle adjustment of the second bracket 4

[0113] By passing the first screw through the connecting hole 410 on the third support 41, the second bracket 4 is initially fixed to the mounting plate 6. According to the actual docking requirements, the angle of the second bracket 4 relative to the mounting plate 6 is adjusted by rotation; after the angle adjustment is completed, the second screw is passed through the arc-shaped through hole 411 to finally lock and fix the second bracket 4 to the mounting plate 6.

[0114] 3. Installation of docking component 1

[0115] The assembled elastic buffer assembly (including conduit 21, fixing tube 22, limiting member 23 and elastic member) is fixed to the output end of conduit 21 with the third screw to ensure a firm connection and good sealing.

[0116] 4. The first bracket and the elastic buffer assembly are installed onto the second bracket.

[0117] First, a connecting nut 5 is fitted onto one end of the fixing tube 22; then, the first support 31 is fitted onto the outside of the fixing tube 22; next, the elastic buffer assembly consisting of the fixing tube 22 and the guide tube 21 is passed through the through hole at the bottom of the fourth support 42; finally, another connecting nut 5 is installed at the other end of the fixing tube 22, so that the two connecting nuts 5 are located on both sides of the fourth support 42. By tightening the two connecting nuts 5, the first bracket 3 and the elastic buffer assembly 2 are securely locked onto the second bracket 4.

[0118] 5. Installation of detection components

[0119] The detection component is mounted on the second support 32 of the first bracket 3 and positioned above the inlet end of the conduit 21. The specific installation position of the detection component can be fine-tuned according to actual needs to ensure that it can accurately detect the displacement changes of the conduit 21.

[0120] 6. Inflation line connection and overall machine inspection

[0121] Connect one end of the inflation tube with the solenoid valve to the input end of the conduit 21, and the other end to the gas source. After assembling all components, conduct a comprehensive inspection of the entire device to confirm that all parts are installed correctly and that there are no omissions. Pay special attention to checking that all fasteners are tightened without looseness, that the expansion and contraction of the conduit 21 under the action of the elastic element is smooth and that the expansion and contraction range is reasonable, and that the connectors can rotate flexibly without jamming. At the same time, check for foreign objects inside the pipes and connectors. If any are found, clean them promptly to ensure that the system is clean, unobstructed, and free from any obstructions.

[0122] According to an embodiment of the present invention, an automatic inflation docking device is provided, comprising: a docking component 1, an elastic buffer component 2, and a detection component. The docking component 1 is used to dock with the connection part of the device to be inflated. The elastic buffer component 2 is movably disposed and has a conveying part and a fixing part. The input end of the conveying part is used to connect to a gas source, and the output end of the conveying part is connected to the docking component 1. The fixing part is sleeved on the conveying part, and the conveying part is movably disposed relative to the fixing part in a preset direction so that when the docking component 1 docks with the connection part of the device to be inflated, the conveying part moves relative to the fixing part. The detection component is used to detect the displacement of the conveying part relative to the fixing part in a preset direction away from the docking component 1, and to determine the docking state of the docking component 1 and the device to be inflated based on the detected displacement.

[0123] As can be seen, the automatic inflation docking device provided by this utility model includes a docking component 1, an elastic buffer component 2, and a detection component. The docking component 1 is used to dock with the connection part of the device to be inflated, so as to facilitate the inflation operation of the device.

[0124] The elastic buffer assembly 2 includes a fixing part and a conveying part. The fixing part is sleeved on the conveying part, and the conveying part can move relative to the fixing part in a preset direction. The input end of the conveying part is used to connect to a gas source, and its output end is connected to the docking assembly 1. Thus, after the docking assembly 1 completes docking with the connection part of the device to be inflated, the gas output from the gas source can be conveyed to the device to be inflated in sequence through the conveying part and the docking assembly 1.

[0125] In addition, the detection component is used to detect the amount of displacement of the conveying part relative to the fixed part in a preset direction away from the docking component 1 during the docking process, and to determine the docking status between the docking component 1 and the device to be inflated based on the amount of displacement.

[0126] Therefore, by setting up the docking component 1, rapid and precise docking with the connection part of the device to be inflated can be achieved, significantly reducing the time and effort required for manual alignment and improving docking efficiency. Simultaneously, the excellent fit between the docking component 1 and the connection part ensures smooth gas transmission, effectively preventing gas leakage and guaranteeing high efficiency and stability during the inflation process. Furthermore, the precise docking method reduces the risk of gas leakage due to poor docking and avoids the problem of direct welding due to potential nitrogen filling failure.

[0127] Furthermore, the fixing part of the elastic buffer assembly 2 is sleeved on the outside of the conveying part, and the conveying part has the ability to reciprocate relative to the fixing part in a preset direction. When the docking assembly 1 contacts the connecting part of the device to be inflated and docking pressure is applied, this structural design allows the conveying part to adjust its position within a certain range, thereby avoiding rigid contact between the docking assembly 1 and the connecting part and playing a buffering and protective role. This not only extends the service life of the docking assembly and the device to be inflated, but also effectively ensures the stability and sealing of the connection between the two.

[0128] Furthermore, by incorporating a detection component, the displacement of the conveying unit relative to the fixed unit along a preset direction away from the docking component 1 can be monitored in real time during the docking process. This allows for rapid determination of whether the docking component 1 has achieved a proper docking with the equipment to be inflated. If an abnormal displacement is detected, the detection component can promptly issue a warning signal to alert the operator. Precise detection of displacement ensures that the docking component 1 remains in the correct docking state. This precise monitoring mechanism overcomes the shortcomings of traditional manual judgment methods, improving the reliability and intelligence of the entire docking process. Simultaneously, the displacement detection function of the detection component provides operators with clear docking status information, eliminating the need for frequent manual checks on docking success and simplifying the operational process.

[0129] In summary, the automatic inflatable docking device provided by this utility model achieves automation and intelligence in the docking process through the synergistic effect of docking component 1, elastic buffer component 2, and detection component. It not only effectively reduces the labor intensity of manual assembly processes and improves nitrogen filling quality and inflatable efficiency, but also solves the technical problem in the prior art where nitrogen filling equipment cannot monitor the docking status in real time, which may lead to nitrogen filling failure and direct welding.
