Description

Technical Field

[0001] This invention relates to the field of hydraulic pump suspension and conveying technology, and more specifically, to a conveying device for hydraulic pump processing and assembly. Background Technology

[0002] The conveying device for hydraulic pump processing and assembly is a conveying equipment used in the hydraulic pump production and assembly process for assembling and transferring the hydraulic pump housing and its internal structural components. It can complete the station transfer of hydraulic pump housing workpieces and realize the step-by-step assembly of various internal components. Since the hydraulic pump housing is the base bearing component of the hydraulic pump and undertakes the installation and positioning tasks of internal valve cores, seals, and oil passage components, the assembly accuracy of the housing directly affects the sealing performance and operational reliability of the hydraulic pump. Therefore, in the process of assembling the hydraulic pump housing, a suspended conveying device is usually used for conveying.

[0003] Currently, in the process of assembling and conveying hydraulic pump housings, the main controller is usually started first. The main controller drives the first robotic arm to grab the hydraulic pump housing and place it on the hook of the suspended conveying mechanism. Then, the suspended conveying mechanism is started to transport the housing workpiece to the next assembly workbench. The second robotic arm on the workbench uses its own fixing mechanism to clamp the hydraulic pump housing and accurately place the housing in the positioning position on the workbench. Then, the assembly of the internal components of the hydraulic pump housing is completed on the workbench, realizing the automated flow and assembly of the workpiece between multiple workstations.

[0004] However, the existing suspended conveying device still has the following obvious defects in the long-term conveying of hydraulic pump housings: Due to the continuous friction between the lifting rollers and the lower flange of the I-beam rail in the conveying device, the cross-sectional thickness of the lower flange gradually decreases, resulting in a gradual decrease in the load-bearing capacity of the rail. This makes the lower flange of the I-beam rail prone to local plastic deformation when the conveying device continuously conveys the hydraulic pump housing, causing continuous bumps and swaying during the conveying process. This reduces the stability and positioning accuracy during the conveying process. This not only easily causes wear and damage to the hydraulic pump housing mounted on the hook of the conveying equipment, reducing the production yield of the hydraulic pump housing products, but also causes deviations in the conveying path of the hydraulic pump housing. As a result, the positioning accuracy of the hydraulic pump housing on the conveying line decreases, affecting the accuracy of docking and gripping the material by the robotic arm in the subsequent conveying device. This can easily lead to material unloading failure, production line interruption, and reduced production efficiency.

[0005] In view of this, we propose a conveying device for hydraulic pump processing and assembly. Summary of the Invention

[0012] As an optional solution of the technical solution in this invention document, an air pressure monitoring chamber is provided inside the airbag sleeve and located at the roller, and multiple patch pressure sensors are arranged in a circular array along the circumference of the airbag sleeve inside the air pressure monitoring chamber.

[0013] As an optional solution of the technical solution in this invention document, the interior of the plurality of U-shaped plates is provided with a gas storage chamber, and the interior of the gas storage chamber and the airbag sleeve are both filled with high-pressure gas. A pair of delivery pipes are installed symmetrically inside the gas storage chamber, and the two delivery pipes pass through the corresponding sensing chambers respectively.

[0014] As an optional solution to the technical solution of this invention, one end of the conveying pipe is fixedly connected to a rotary joint, and one end of each of the rotary joints passes through the interior of the roller through a branch pipe and is connected to the interior of the airbag sleeve.

[0015] As an optional solution to the technical solution of this invention, a fixing block is installed on the outer surface of the rotary joint, and the side of the fixing block is connected to the inner wall of the sensing chamber.

[0016] As an optional solution to the technical solution of this invention, a miniature one-way pressure holding valve is installed on the pipeline of the plurality of rotary joints, and an air pump is installed on the pipeline of the rotary joint near the miniature one-way pressure holding valve.

[0017] As an optional solution to the technical solution of this invention, both microvascular one and microvascular two are three-dimensional mesh structures, and the intersection of the mesh structures forms a joint node. The interior of microvascular one is filled with resin repair agent, and the interior of microvascular two is filled with hardener.

[0018] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. By combining the distance sensor and laser displacement sensor within the deformation and wear sensing component, the wear thickness of the rollers on the lower flange of the I-beam rail and the bending deformation of the thinned lower flange under heavy loads can be detected in real time during long-term continuous high-altitude conveying of the hydraulic pump housing. This accurately detects early hidden defects such as thickness reduction or buckling wave deformation caused by long-term friction of the rail. When the load-bearing capacity of the I-beam rail decreases or the deformation exceeds the preset value, an early warning signal can be output in time to remind the staff to carry out timely inspection and replacement, avoiding the continuous deterioration of the conveying conditions due to rail defects. This avoids the problems of hook bumps and workpiece shaking caused by uneven rails from the source, improves the stability of the hydraulic pump housing during high-altitude conveying, and reduces the probability of wear and damage to the hydraulic pump housing mounted on the hook during conveying, thereby helping to improve the production yield of hydraulic pump housing products.

[0019] 2. Through the coordinated operation of the airbag sleeve, wear-resistant layer, and nylon cord layer within the vibration damping load-bearing component, the flexible buffering characteristics of the airbag sleeve can adaptively offset the height difference and impact vibration caused by track wear and thinning, and wave deformation. This significantly improves the flatness and assembly stability of the hydraulic pump housing during transport. Simultaneously, it can evenly disperse the localized concentrated compressive stress in the contact between the rollers and the track, preventing localized stress concentration from accelerating track plastic wear and buckling deformation. This effectively slows down the wear and thinning rate of the lower flange of the I-beam, thereby suppressing deviations in the hydraulic pump housing's transport path, maintaining the positioning accuracy of the hydraulic pump housing on the transport line, ensuring the accuracy of subsequent robotic arm docking and material handling, reducing material handling failures, preventing production line interruptions, improving production efficiency, and further reducing the frequency of equipment component replacements and the overall operation and maintenance costs of the production line.

[0020] 3. Through the cooperation of the patch-type pressure sensor, air pump and miniature one-way pressure holding valve inside the air pressure monitoring chamber, the air pressure fluctuation signal inside the airbag can be collected in real time and the real-time load of the roller can be accurately calculated. This enables dynamic adaptive adjustment of the airbag sleeve support stiffness. When air pressure decays or support performance declines during long-term conveying operations, the equipment can automatically complete precise air replenishment and pressure stabilization operations. The miniature one-way pressure holding valve stabilizes and locks the internal pressure, ensuring that the roller maintains appropriate buffer support performance under different load conditions. This continuously ensures the spatial positioning accuracy of the hydraulic pump shell transfer docking, effectively improving the matching degree of the robotic arm docking, gripping and unloading.

[0021] 4. Through the cooperation of the nylon cord layer inside the airbag sleeve with the three-dimensional mesh micro-vessels one and two, when the nylon cord layer experiences fiber fatigue fracture during long-term operation under alternating compressive stress, the fractured fibers can precisely pierce micro-vessels one and two, allowing the resin repair agent and hardener to flow out from micro-vessels one and two respectively. They then rapidly mix and undergo cross-linking polymerization and curing reactions in the interlayer chamber, thereby reinforcing the fractured fibers, restoring local tensile strength, effectively preventing the continuous propagation of microcracks, and eliminating the problem of local bulging of the airbag sleeve from the root.

[0022] 5. Meanwhile, relying on their own three-dimensional mesh joint node structure, micro-vessels one and two can achieve long-term sealing and leak-proof of the agent in the undamaged area of ​​the nylon cord layer, extend the service life of the nylon cord layer, reduce the frequency of parts replacement, and effectively avoid the risk of the airbag sleeve being scratched by the rough protrusion formed by the wear of the lower flange during the movement of the roller after local bulging. It also prevents secondary bumps caused by air leakage due to airbag sleeve damage when the roller moves in the track, further ensuring the stability and safety of the conveying process.

[0023] 6. Through the synergistic assistance of micro-pulse one and micro-pulse two, the local compressive stress and interlayer shear stress generated by the rolling contact of the rollers can be quickly dispersed to the overall mesh structure under normal conveying conditions. This effectively weakens the phenomenon of stress concentration at single points, distributes the load-bearing capacity of a single nylon fiber, efficiently dissipates the shear force generated by rolling friction, significantly reduces the fatigue damage rate of the nylon cord layer, and improves the overall fatigue resistance of the airbag sleeve. This further ensures the stability of the device during long-term continuous conveying operations, maintains the conveying positioning accuracy, reduces material feeding failures caused by airbag sleeve fatigue failure, and ensures continuous production of the production line.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Example 1: Please refer to Figures 1 to 12 The first embodiment of the present invention provides a technical solution: including a suspended conveyor frame 1, an I-beam rail 101 installed at the bottom of the suspended conveyor frame 1, a plurality of U-shaped plates 102 assembled along the length of the I-beam rail 101, rollers 103 rotatably connected to both sides of the U-shaped plates 102 through bearings, a deformation and wear sensing component 2 disposed inside the U-shaped plates 102, and a vibration damping bearing component 3 disposed inside the rollers 103.

[0041] Specifically, the deformation and wear sensing component 2 includes two sensing chambers 201 located inside the U-shaped plate 102. The two sensing chambers 201 are respectively arranged corresponding to the rollers 103 on both sides of the U-shaped plate 102. A distance sensor 202 is fixedly connected to the inner cavity sidewall of the sensing chamber 201, and a laser displacement sensor 203 is fixedly connected to the inner cavity sidewall of the sensing chamber 201 near the distance sensor 202. The distance sensor 202 can detect the wear thickness of the lower flange 107 of the I-beam in real time and accurately monitor the vertical wear degree of the track. At the same time, the laser displacement sensor 203 synchronously detects the overall bending deformation and lateral deviation deformation of the I-beam track 101. The two sets of sensors work together to perform all-weather real-time quantitative monitoring of the wear and deformation state of the I-beam track 101. When the monitoring values ​​collected by the distance sensor 202 and the laser displacement sensor 203 exceed the system's preset threshold, the abnormal signal can be transmitted to the main controller in a timely manner to trigger the alarm light and remind the operator to inspect and replace the track in time to avoid operating the equipment with a fault.

[0042] Please see Figures 5 to 8An air pressure monitoring chamber 205 is installed inside the airbag sleeve 301 and located at the roller 103. Multiple patch pressure sensors 204 are arranged in a circular array around the airbag sleeve 301 inside the air pressure monitoring chamber 205. During long-term conveying conditions, the airbag sleeve 301 will continuously bear heavy-load compression, alternating stress and repeated deformation, which may easily lead to problems such as slow air leakage, air pressure decay or pressure unevenness. Through multiple sets of patch pressure sensors 204, the air pressure fluctuation change signal inside the airbag sleeve 301 can be collected in real time from all directions without blind spots, accurately monitoring the inflation pressure, air pressure decay and pressure distribution inside the airbag sleeve 301. It can promptly detect abnormal air pressure drop inside the airbag sleeve 301, accurately determine the pressure bearing status of the airbag sleeve 301, and provide accurate data basis for subsequent automatic air replenishment and pressure stabilization control of the equipment. It effectively avoids the situation where the airbag sleeve 301 is insufficient in support stiffness and buffer failure due to long-term pressure fatigue and air leakage, ensuring the stable bearing and buffering performance of the roller 103 and the smooth conveying conditions throughout the process.

[0043] Please see Figures 4 to 9 The vibration damping and bearing component 3 includes an airbag sleeve 301 fixedly connected to the outer surface of multiple rollers 103. A wear-resistant layer 302 is fixedly connected to the outer surface of the airbag sleeve 301. Multiple U-shaped plates 102 have internal air storage chambers 303. Both the air storage chambers 303 and the airbag sleeve 301 are filled with high-pressure gas. The airbag sleeve 301 is made of special nitrile rubber or polyurethane material. Through the high-pressure gas filling the airbag sleeve 301, the rollers 103, during their movement and bearing load with the U-shaped plates 102, connecting rods 104, and hooks 105, can absorb and offset the impact vibration caused by uneven wear and wave deformation of the I-beam rail 101 through their own elastic deformation. This effectively buffers the hard bumps caused by track height deviations. Simultaneously, the airbag sleeve 301 can evenly distribute the localized concentrated stress generated by the contact between the rollers 103 and the I-beam rail 101, preventing the rollers 103 from rigidly bearing pressure and causing localized track squeezing. The compression deformation continuously ensures the buffering and vibration reduction effect and load-bearing stability of the hook 105 during the conveying process. Furthermore, the airbag sleeve 301 and wear-resistant layer 302 can reduce the extrusion wear and friction loss of the lower flange 107 of the I-beam during the movement of the roller 103. This effectively alleviates the problems of wear thinning, plastic buckling and wave deformation of the lower flange 107 caused by long-term pressure. This reduces the probability of wear and damage to the outer shell 106 of the hydraulic pump mounted on the hook 105 during the conveying process, thereby helping to improve the production yield of the hydraulic pump shell product. Moreover, the wear-resistant layer 302 can isolate the direct frictional contact between the track and the airbag sleeve 301 body, greatly reducing the sliding wear and extrusion wear generated during the reciprocating rolling of the roller 103. This effectively reduces the wear degree of the inner airbag sleeve 301, significantly improves the overall service life of the airbag sleeve 301, and ensures the structural integrity of the vibration damping load-bearing component 3 during long-term operation.

[0044] Please see Figures 6 to 7The outer wall of the U-shaped plate 102 is connected to the gas storage chamber 303 by an injection pipe. A cover plate is threaded onto the outer surface of the injection pipe. Unscrewing the cover plate allows high-pressure gas to be added to the gas storage chamber 303. After injection, tightening the cover plate seals the injection pipe, preventing leakage of high-pressure gas from the gas storage chamber 303. This allows for gas supply when the gas level in the gas storage chamber 303 is insufficient, ensuring a sufficient and stable gas supply for continuous operation. It provides continuous gas support for subsequent pressure adjustment and replenishment operations when the air pressure in the airbag sleeve 301 decreases or its support rigidity is insufficient, enabling dynamic adjustment of the internal pressure of the airbag sleeve 301. The interior of the gas storage chamber 303 is centrally symmetrical. A pair of delivery pipes 304 are installed, with each delivery pipe 304 passing through a corresponding sensing chamber 201. One end of each delivery pipe 304 is fixedly connected to a rotary joint 308. One end of each rotary joint 308 passes through a branch pipe and connects to the inside of the roller 103 and the airbag sleeve 301. Since the roller 103 continuously rotates during the walking and conveying process, the rotary joints 308 can completely prevent the delivery pipes 304 from rotating synchronously with the roller 103, effectively preventing the delivery pipes 304 from twisting, tangling, bending, or tearing. This ensures that the air passage remains unobstructed and sealed during the continuous rolling operation of the roller 103, ensuring that the air replenishment and pressure stabilization operation can be carried out normally at any time.

[0045] Please see Figure 7 A fixing block 307 is installed on the outer surface of the rotary joint 308. The side of the fixing block 307 is connected to the inner wall of the sensing chamber 201. The fixing block 307 can support the delivery pipe 304. A miniature one-way pressure holding valve 305 is installed on the pipeline of multiple rotary joints 308. An air pump 306 is installed on the pipeline of the rotary joint 308 near the miniature one-way pressure holding valve 305. When the patch pressure sensor 204 detects that the air pressure inside the airbag sleeve 301 has decreased and cannot adapt to the current load condition, the main controller automatically starts the air pump 306 and delivers air through the delivery pipe 304 and rotary joint 308. The air passage formed by the head 308 replenishes the high-pressure gas inside the air storage chamber 303 into the airbag sleeve 301, realizing automatic compensation of air pressure and stiffness adjustment of the airbag sleeve 301. This allows the roller 103 to adaptively match the support strength according to light and heavy load conditions, ensuring smooth conveying. This suppresses deviations in the conveying path of the hydraulic pump housing 106, maintains the positioning accuracy of the hydraulic pump housing 106 on the conveying line, ensures the accuracy of subsequent robotic arm docking and material handling, reduces material handling failures, avoids production line interruptions, improves production efficiency, and further reduces the frequency of equipment component replacement and the overall operation and maintenance cost of the production line.

[0046] Please see Figures 1 to 5The U-shaped plate 102 is connected to the traction chain inside the suspended conveyor frame 1. The I-beam rail 101 has an upper flange and a lower flange 107. The outer surface of the roller 103 rolls in contact with the upper surface of the lower flange 107 and the lower surface of the upper flange. Connecting rods 104 are provided at the bottom of multiple U-shaped plates 102. The lower end of the connecting rod 104 is hinged to a hook 105 via a pin. The outer surface of the hook 105 is engaged with a hydraulic pump housing 106. The engagement structure of the hook 105 achieves stable mounting and fixing of the hydraulic pump housing 106, completing the process. The suspended conveyor frame 1 is fixedly connected to a workbench on its outer side, and a robotic arm is connected to the side of the workbench via a fixed plate. A drive mechanism is fixedly connected to the upper surface of the suspended conveyor frame 1. The drive mechanism includes a drive motor and a reducer. The output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the traction chain drive. The drive mechanism is used to drive the traction chain to run in a cycle. The drive mechanism outputs power to drive the traction chain to run in a cycle, thereby driving the U-shaped plate 102 to move in a cycle along the I-beam track 101 to transport the workpiece.

[0047] Please see Figures 1 to 3 The outer surface of the robotic arm is equipped with a fixing mechanism, which can clamp, position, and transfer the hydraulic pump housing 106 that has been delivered to the designated location, facilitating assembly operations by the operator. A main controller is fixedly connected to the side of the workbench. The main controller has a built-in power supply, and all electrical components of the equipment are electrically connected to the internal power supply of the main controller via cables to realize power supply, signal reception, and command control of the entire machine. Multiple support rods are fixedly connected to the bottom of the workbench, and an alarm light is fixedly connected to the upper surface of the suspended conveyor frame 1. The alarm light is electrically connected to the main controller via a circuit. When the deformation and wear sensing component 2 detects that the wear thickness, bending deformation, or lateral deviation of the I-beam rail 101 exceeds the preset safety threshold, the main controller can quickly receive the abnormal signal and trigger the alarm light to illuminate as a warning, promptly prompting the operator to stop the machine for inspection and maintenance, and replace the damaged rail, thus avoiding defects such as conveyor bumps caused by the equipment continuing to operate with faults.

[0048] Example 2: The difference between this example and Example 1 is that the vibration damping load-bearing component 3 is provided with a fabric micro-damage blocking component 4.

[0049] Specifically, the fabric micro-damage blocking component 4 includes a sandwich chamber 403 inside the airbag sleeve 301. A micro-vessel 1 401 is fixedly connected to the inner wall of the sandwich chamber 403 near the wear-resistant layer 302, and a micro-vessel 2 402 is fixedly connected to the inner wall of the sandwich chamber 403 near the airbag sleeve 301. Both micro-vessel 1 401 and micro-vessel 2 402 are made of flexible, high-elasticity, high-polymer thin-walled tube material, which can adapt to the long-term repeated compression and deformation of the airbag sleeve 301. It will not crack, leak or fail due to the elastic expansion and contraction of the airbag sleeve 301 or the rolling impact of the track, and at the same time, it does not affect the flexible buffering and deformation performance of the airbag sleeve 301 itself.

[0050] Please see Figures 8 to 12 A nylon cord layer 404 is installed between micro-vessel one 401 and micro-vessel two 402. Both micro-vessel one 401 and micro-vessel two 402 are three-dimensional mesh structures, and the intersection of the mesh structures forms a joint node. The interior of micro-vessel one 401 is filled with resin repair agent, and the interior of micro-vessel two 402 is filled with hardener. Under normal equipment conveying conditions and when the nylon cord layer 404 does not show fiber damage or breakage, the resin repair agent and hardener inside micro-vessel one 401 and micro-vessel two 402 can quickly disperse the local extrusion stress and interlayer shear force generated by the rolling contact of the roller 103, and distribute the load-bearing capacity of the nylon cord layer 404, reducing the fatigue wear of the nylon cord layer 404. Furthermore, when the airbag sleeve 301 is subjected to alternating extrusion for a long time... When compressive stress causes fatigue fracture of local fibers in the nylon cord layer 404, the broken fiber ends can directly pierce the corresponding damaged microvessels 401 and 402, causing the resin repair agent inside microvessel 401 and the hardener inside microvessel 402 to flow out rapidly and mix quickly at the damaged location in the interlayer chamber 403, undergoing a cross-linking polymerization and curing reaction. The liquid quickly solidifies into a high-strength solid polymer, which firmly bonds the broken fiber structure, effectively restores the local tensile strength of the nylon cord layer 404, blocks the continuous extension and expansion of microcracks, further ensures the stability of the device during long-term continuous conveying operations, maintains the conveying positioning accuracy, reduces material feeding failures caused by fatigue failure of the airbag sleeve 301, and ensures continuous production of the production line.

[0051] Working principle: In use, the operator first starts the equipment into standby mode through the main controller. The drive motor and reducer inside the drive mechanism work together to drive the traction chain inside the suspended conveyor frame 1 to rotate in a cycle. The traction chain synchronously drives each group of U-shaped plates 102 to move along the length of the I-beam rail 101. The rollers 103 on both sides of the U-shaped plate 102 simultaneously roll along the upper surface of the lower flange 107 and the lower surface of the upper flange of the I-beam rail 101. The rollers 103 support the overall weight of the U-shaped plate 102, connecting rod 104, hook 105 and hydraulic pump housing 106, realizing the continuous high-altitude flow and conveying of the hydraulic pump housing 106. When it is conveyed to the workbench, it is placed on the workbench by the fixing mechanism on the robotic arm so that the operator can assemble the hydraulic pump housing 106. This cycle is repeated.

[0052] During the entire conveying operation, as the traction chain inside the suspended conveyor frame 1 circulates and drives the overall movement of the lifting device, the deformation and wear sensing component 2 inside the U-shaped plate 102 is continuously in a real-time monitoring state. The distance sensor 202 in the two sets of sensing chambers 201 inside the U-shaped plate 102 collects the remaining thickness data of the lower flange 107 of the I-beams on both sides in real time, accurately monitoring the vertical wear degree of the track. The laser displacement sensor 203 simultaneously detects the bending deformation and lateral deviation of the I-beam track 101. The main controller summarizes the monitoring data in real time and accurately determines whether the track wear and deformation have reached the scrapping standard. Once the monitoring data exceeds the standard, the alarm light is immediately triggered to remind the staff to repair and replace the track in time, so as to avoid the continuous operation with faults aggravating the conveying defects.

[0053] During the operation of the I-beam rail 101, regardless of whether there is slight wear on the rail, the airbag sleeve 301 on the surface of the roller 103 continuously provides flexible elastic cushioning. If the lower flange 107 wears thin and becomes wavy, the airbag sleeve 301 can adaptively offset the bumps and vibrations caused by uneven wear on the rail, greatly improving the flatness and stability of the hydraulic pump housing 106 during the conveying process. At the same time, it effectively disperses the local contact stress of the roller 103, slows down the wear thinning and buckling deformation rate of the lower flange 107 of the I-beam, thereby improving the stability of the hydraulic pump housing 106 during high-altitude conveying, reducing the probability of wear and damage to the hydraulic pump housing 106 that is hung on the hook 105 during the conveying process, and thus helping to improve the production yield of the hydraulic pump housing 106. Furthermore, it ensures that the roller 103 always maintains appropriate cushioning and support performance under different load conditions, continuously ensuring the spatial positioning accuracy of the hydraulic pump housing 106 transfer and docking, and effectively improving the matching degree of the robotic arm docking, gripping and unloading.

[0054] Furthermore, during the movement and load-bearing process of the roller 103, the main controller will simultaneously activate the patch pressure sensor 204 in the air pressure monitoring chamber 205 to collect air pressure change signals in real time. The main controller accurately calculates the real-time load of the roller 103 through air pressure changes. When the air pressure is detected to be too low or the support stiffness is insufficient, the patch pressure sensor 204 will immediately transmit the signal to the main controller, causing the main controller to immediately start the air pump 306. This allows the gas in the air storage chamber 303 to be automatically replenished into the airbag sleeve 301 through the delivery pipe 304, rotary joint 308, and branch pipe. This works in conjunction with the miniature one-way pressure holding valve 305 to maintain a constant internal air pressure. When the patch pressure sensor 204 detects that the pressure of the airbag sleeve 301 has reached the preset value, it will immediately transmit this signal to the main controller, causing the main controller to immediately shut down the air pump 306 and stop injecting high-pressure gas into the corresponding airbag sleeve 301.

[0055] Under long-term alternating compressive stress, the internal nylon cord layer 404 is prone to fiber fatigue fracture. When a fiber in the nylon cord layer 404 fractures due to fatigue, the fractured fiber simultaneously punctures the corresponding three-dimensional network structure of microvessels 401 and 402, causing the internal resin repair agent and hardener to mix rapidly and undergo a cross-linking polymerization reaction. This rapidly solidifies the liquid into a high-strength solid polymer, fixing the fractured fiber, restoring local tensile strength, and preventing the continued propagation of microcracks. Simultaneously, relying on their own three-dimensional network joint structure, microvessels 401 and 402 can prevent fiber fractures in other locations. Liquid leakage inside 401 and micro-pulse 402 is prevented, maintaining the long-term sealed storage of the medicine and extending the service life of the fabric micro-damage blocking component 4. Until the patch pressure sensor 204 detects abnormal air pressure in the airbag sleeve 301 and determines that the airbag sleeve 301 has leaked and failed, the airbag sleeve 301 is replaced as a whole, and the fabric micro-damage blocking component 4 is replaced along with the airbag sleeve 301. This effectively avoids the risk that the airbag sleeve 301 will be punctured by the wear spikes of the lower flange 107 during the movement of the roller 103 after a partial bulge. It also prevents secondary bumps caused by the airbag sleeve 301 breaking and leaking air when the roller 103 moves in the track, further ensuring the stability and safety of the conveying process.

[0056] Under normal conveying conditions, micro-vessel 1 401, micro-vessel 2 402, and the repair and hardening agents filled inside them can serve as flexible buffer media between the layers of nylon cord fabric 404. Relying on the extensibility of the three-dimensional network structure and the incompressible nature of the medium volume, the localized concentrated stress generated by the pressure on the roller 103 is quickly dispersed to the entire network structure, avoiding stress concentration on a single nylon fiber. This significantly reduces the stress load on the nylon cord fabric 404, effectively dissipates the interlayer shear force generated by the contact and rolling of the roller 103 and the I-beam rail 101, reduces the fatigue damage rate of the nylon cord fabric 404, further ensures the stability of the device during long-term continuous conveying operations, maintains the conveying positioning accuracy, reduces material feeding failures caused by the fatigue failure of the airbag sleeve 301, and ensures continuous production of the production line.
