Description

Technical Field

[0001] This utility model relates to the technical field of integrated knitting and forming devices, and in particular to an adaptive tension-adjustable irregular-shaped integrated knitting and forming device. Background Technology

[0002] Traditional irregular-shaped braiding devices mostly employ fixed molds and a single motion trajectory, which is difficult to adapt to the molding requirements of complex three-dimensional curved structures. Furthermore, the braiding tension relies on manual experience for adjustment, easily leading to defects such as uneven wire tension and interlayer misalignment. In existing technologies, limitations in mold posture adjustment, fixed wire feeding angles, and environmental factors such as temperature, humidity, and vibration further affect braiding accuracy and consistency. Moreover, the lack of real-time tension monitoring and closed-loop control mechanisms makes it difficult to achieve high-quality integrated molding of irregularly shaped parts. Therefore, there is an urgent need for an intelligent braiding device with multi-degree-of-freedom dynamic adjustment, adaptive tension compensation, and environmental stability control to solve the key technical bottlenecks in the molding of complex irregular-shaped woven fabrics. Utility Model Content

[0003] The main purpose of this invention is to provide an adaptive tension-adjustable integral knitting forming device for irregular shapes, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adaptive tension-adjustable irregular-shaped integrated braiding molding device includes: a base plate, on which a transverse moving mechanism is fixedly installed in the middle of its top surface, and a spatial moving mechanism is installed at the top moving end of the transverse moving mechanism; A spatial movement mechanism, wherein a mold fixing component is installed at its moving end, the spatial movement mechanism includes a first electric slide rail, a second electric slide rail and a rotary drive module, used to drive the mold fixing component to translate and rotate in three-dimensional space; The weaving moving components are symmetrically distributed on both sides of the lateral moving mechanism. Each group includes a linear module driven by a servo motor, and the moving end of the module is equipped with a weaving mechanism. The knitting mechanism includes a fixed base, a rotating ring, a knitting inlet, a knitting outlet, and a front knitting tube. The fixed base is fixed to the moving end of the knitting moving component. The rotating ring is rotatably connected to the fixed base through a bearing and has a steering wheel set and a tension sensor inside. One end of the front knitting tube is hinged to the rotating ring, and the other end is the knitting outlet. The control unit, integrated inside the substrate, receives tension sensor signals and regulates the motion parameters of the lateral movement mechanism, spatial movement mechanism, and weaving movement component to achieve adaptive closed-loop adjustment of weaving tension. The protective cover is fixed to the top of the base plate, with an observation door hinged on one side, a directional air inlet at the top, and an exhaust outlet at the bottom, forming a closed woven environment.

[0005] Preferably, the steering wheel assembly of the rotating ring includes: an active guide wheel driven by a micro servo motor for adjusting the wire feeding angle; a driven clamping wheel that forms a clamping channel with the active guide wheel through a spring loading mechanism, the pressure value of which is monitored in real time by a tension sensor; and the braided inlet passing through the rotating ring and communicating with the interior of the front braided tube.

[0006] Preferably, the front braided tube is provided with a clamping assembly, including: a pneumatic gripper that adaptively adjusts the clamping force according to the wire diameter; a pressure feedback module that monitors the clamping pressure in real time and transmits it to the control unit; and the braided material outlet of the front braided tube corresponds to the irregular mold position of the mold fixing assembly.

[0007] Preferably, the rotation drive module of the spatial movement mechanism is a six-degree-of-freedom parallel robotic arm with a mold fixing component at the end, including: an electromagnetic chuck for adsorbing and fixing irregular molds; and a tilt compensation module with a built-in gyroscope sensor and a fine-tuning motor to dynamically correct mold posture deviations.

[0008] Preferably, the directional air inlet of the protective cover is connected to a temperature and humidity regulator and a multi-stage filtration device, and the exhaust outlet has a built-in negative pressure fan and a vibration isolation layer to maintain a constant temperature, humidity and clean environment inside the cover and suppress external vibrations.

[0009] Preferably, the visual inspection system includes a high-speed camera fixed inside the protective housing, aimed at the exit area of ​​the woven fabric; the control unit integrates a defect analysis module, which detects surface defects of the woven fabric based on image recognition technology and triggers compensation commands.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By monitoring the wire tension in real time through the tension sensor inside the rotating ring, and combining the motion parameters of the lateral movement mechanism and the braiding movement component with the control unit, the wire is evenly distributed, which significantly reduces the risk of interlayer misalignment in irregularly shaped braided fabrics and improves the forming accuracy.

[0011] By working together with the directional air inlet and outlet of the protective cover, along with a multi-stage filtration system and vibration isolation layer, dust, temperature and humidity fluctuations and external vibrations are effectively isolated, maintaining a stable environment during the weaving process and reducing wire contamination and weaving defects.

[0012] The vision inspection system (high-speed camera) captures images of the woven fabric exit area in real time. After the defect analysis module identifies anomalies, it triggers the compensation action of the spatial movement mechanism to achieve closed-loop defect correction, reduce manual intervention, and improve production continuity and yield.

[0017] The spatial movement mechanism 7 has a mold fixing component 8 installed at its moving end. The spatial movement mechanism 7 includes a first electric slide rail 71, a second electric slide rail 72 and a rotary drive module 73, which are used to drive the mold fixing component 8 to translate and rotate in three-dimensional space.

[0018] The weaving moving components 10 are symmetrically distributed on both sides of the transverse moving mechanism 6. Each group includes a linear module driven by a servo motor, and its moving end is equipped with a weaving mechanism 9.

[0019] The knitting mechanism 9 includes a fixed base 91, a rotating ring 92, a knitting inlet 93, a knitting outlet 94, and a front knitting tube 95. The fixed base 91 is fixed to the moving end of the knitting moving assembly 10. The rotating ring 92 is rotatably connected to the fixed base 91 through a bearing. It is equipped with a steering wheel group and a tension sensor 922 inside. One end of the front knitting tube 95 is hinged to the rotating ring 92, and the other end is the knitting outlet 94.

[0020] The control unit, integrated inside the substrate 1, receives signals from the tension sensor 922 and regulates the motion parameters of the lateral movement mechanism 6, the spatial movement mechanism 7, and the weaving movement component 10 to achieve adaptive closed-loop adjustment of the weaving tension.

[0021] The protective cover 2 is fixed to the top of the base plate 1, with an observation door 3 hinged on one side, a directional air inlet 4 at the top, and an exhaust outlet 5 at the bottom, forming a closed woven environment.

[0022] In this embodiment, the steering wheel assembly of the rotating ring 92 includes: an active guide wheel driven by a micro servo motor for adjusting the wire feeding angle; a driven clamping wheel that forms a clamping channel with the active guide wheel through a spring loading mechanism, the pressure value of which is monitored in real time by a tension sensor 922; a braided material inlet 93 that passes through the rotating ring 92 and communicates with the interior of the front braided tube 95; a clamping assembly is provided inside the front braided tube 95, including: a pneumatic gripper that adaptively adjusts the clamping force according to the wire diameter; a pressure feedback module that monitors the clamping pressure in real time and transmits it to the control unit; and a braided material outlet 94 of the front braided tube 95 that corresponds to the irregular mold position of the mold fixing assembly 8.

[0023] Specifically, the coordinated design of the active guide wheel servo drive and the driven clamping wheel spring loading mechanism, through the tension sensor 922 monitoring the wire tension in real time, combined with the linkage control of the first electric slide rail 71 and the second electric slide rail 72, realizes the dynamic adjustment of the wire conveying angle, effectively suppressing the tension fluctuation caused by the sudden change of path in high curvature irregular braiding; the pneumatic gripper adaptive clamping force and pressure feedback module is integrated inside the front braiding tube 95, which automatically adjusts the clamping force according to the wire diameter to avoid the wire displacement deviation caused by high-speed braiding; at the same time, through the pressure feedback and the hinged movement of the rotating ring 92, it ensures the precise alignment of the braided material outlet 94 with the mold fixing component 8, and enhances the interlayer bonding strength.

[0024] In this embodiment, the rotation drive module 73 of the spatial movement mechanism 7 is a six-degree-of-freedom parallel robotic arm with a mold fixing component 8 at its end, including: an electromagnetic chuck 81 for adsorbing and fixing irregularly shaped molds; a tilt compensation module with a built-in gyroscope sensor and a fine-tuning motor to dynamically correct mold posture deviations; a directional air inlet 4 of the protective cover 2 connected to a temperature and humidity regulator and a multi-stage filtration device, and an exhaust outlet 5 with a built-in negative pressure fan and vibration isolation layer to maintain a constant temperature and humidity clean environment inside the cover and suppress external vibrations; a visual inspection system including a high-speed camera 61 fixed inside the protective cover 2, aimed at the woven fabric outlet 94 area; and a control unit integrating a defect analysis module to detect surface defects of the woven fabric based on image recognition technology and trigger compensation commands.

[0025] Specifically, the combination of electromagnetic chuck 81 and six-degree-of-freedom parallel robotic arm rotation drive module 73 enables rapid adsorption and fixation of irregularly shaped molds, as well as spatial posture adjustment. The tilt compensation module, gyroscope sensor, and fine-tuning motor dynamically correct the mold's posture, reducing manual calibration time and making it suitable for rapid mold changeovers of various types and small batches of irregularly shaped parts. The directional air inlet 4 connects to a temperature and humidity regulator, while the exhaust outlet 5 incorporates a built-in negative pressure fan, working in conjunction with a vibration isolation layer to form a stable clean airflow circulation. This effectively isolates external dust pollution and equipment vibration, meeting the high cleanliness and low noise requirements of the aerospace industry for the weaving environment. The vision inspection system's high-speed camera 61 and defect analysis module are aligned with the weaving material outlet 94 area to capture surface defect images in real time. Combined with compensation commands from the control unit to the spatial movement mechanism 7 and the weaving movement component 10, closed-loop correction of weaving defects is achieved, reducing the frequency of manual inspections and improving the efficiency of fully automated production.

[0026] Working principle: Dynamic control of mold: The spatial movement mechanism 7 drives the mold fixing component 8 through a six-degree-of-freedom robotic arm, and combined with the tilt compensation module, corrects the mold posture in real time to ensure the precise alignment of the irregular mold and the woven fabric outlet 94.

[0027] Tension closed-loop control: The wire is conveyed by the steering wheel group in the rotating ring 92, the tension sensor 922 monitors the wire tension in real time, and the control unit adjusts the speed of the servo motor of the braiding moving component 10 and the displacement of the lateral moving mechanism 6 according to the feedback signal to form an adaptive tension adjustment closed loop.

[0028] Environmental stability guarantee: The protective cover 2 receives clean airflow with constant temperature and humidity through the directional air inlet 4, and the negative pressure fan at the exhaust outlet 5 discharges polluted air, suppressing vibration interference and ensuring a stable environment during the weaving process.

[0029] Real-time defect detection: The vision inspection system acquires images of the exit area of ​​the woven fabric. After the defect analysis module identifies surface anomalies, it triggers a spatial movement mechanism or a compensation action for the weaving speed to achieve intelligent quality control.
