[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figures 1 to 3 As shown, this embodiment provides a wingplate shaping device, which includes a main frame 1, multiple shape plates 2, and multiple shaping structures 3. The main frame 1 is shaped like a wingplate, and the multiple shape plates 2 are fixed to the main frame 1. Each shape plate 2 is fixedly connected to at least one shaping structure 3. The shaping structure 3 includes an adsorption component 31, a driving component 32, a force monitoring component 33, a transmission component 34, and a linear motion component 35. The driving component 32 is connected to one end of the linear motion component 35, and the other end of the linear motion component 35 is connected to the adsorption component 31 through the transmission component 34. The linear motion component 35 and the adsorption component 31 are located on the same side of the transmission component 34. The force monitoring component 33 is disposed between the transmission component 34 and the adsorption component 31 to monitor the force applied by the linear motion component 35 to the adsorption component 31.

[0022] The linear motion component 35 applies a force to the adsorption component 31 under the action of the drive component 32. The adsorption component 31 can push or pull the wing panel 100 to deform it, thereby shaping the panel 100. The force monitoring component 33 can monitor the force applied to the panel 100 by the adsorption component in real time. This force includes thrust and pull to ensure the shape control requirements of the panel 100 at all points. The linear motion component and the adsorption component are set on the same side of the transmission component 34, which can reduce the length of the shaping structure 3 and occupy less space. Multiple shaping structures 3 can be arranged to meet the different shape control requirements of the panel 100 at all points, improve the shape control accuracy of the panel 100, and make the panel 100 fit more closely with the wing frame.

[0023] like Figure 2 and Figure 3As shown, in some embodiments, the adsorption assembly 31 includes a suction cup 311, a movable connecting pin 312, and a tension spring 313. One end of the movable connecting pin 312 is connected to the suction cup 311, and the other end of the movable connecting pin 312 is connected to the force monitoring element 33 through the tension spring 313.

[0024] The tension spring 313 can deform under the pull of the movable connecting pin 312, and then gradually apply the tension to the suction cup 311. In this way, the suction cup 311 will not be subjected to a strong force at the moment of being pulled, so that the wall panel 100 will not deform. Under the action of the tension spring 313, the force applied by the suction cup 311 to the wall panel 100 gradually increases to a constant value. In this way, the deformation of the wall panel 100 occurs slowly after being attracted by the suction cup 311. After the force applied to the suction cup 311 is constant, the shape of the wall panel 100 is controlled. The force monitoring component 33 monitors the force applied by the linear motion component 35 in real time to ensure the shape control requirements of the wall panel 100.

[0025] For example, tension spring 313 is a tension spring.

[0026] In some embodiments, the adsorption assembly 31 further includes a tension sleeve 314, a tension spring 313 located inside the tension sleeve 314, one end of the tension spring 313 being fixedly connected to the inner wall of the tension sleeve 314, and the other end of the tension spring 313 being connected to a movable connecting pin 312.

[0027] One end of the tension sleeve 314 away from the movable connecting pin 312 is connected to the force monitoring component 33. The tension spring 313 is placed inside the tension sleeve 314. Thus, the tension spring 313 is compressed or stretched by the force of the tension sleeve 314 and the movable connecting pin 312.

[0028] The tension sleeve 314 protects the tension spring 313 and provides guidance for the tension spring 313 to prevent it from twisting.

[0029] Furthermore, the adsorption assembly 31 also includes a compression spring 315 and a compression sleeve 316. The tension sleeve 314 and the movable connecting pin 312 are located at both ends of the compression sleeve 316 and both extend into the compression sleeve 316. The compression spring 315 is located inside the compression sleeve 316 and is sleeved on the outer periphery of the movable connecting pin 312. One end of the compression spring 315 abuts against the retaining ring 319 of the movable connecting pin 312, and the other end of the compression spring 315 abuts against the end of the tension sleeve 314.

[0030] The compression spring 315 can absorb part of the thrust before the tension sleeve 314 pushes the movable connecting pin 312 to move, and then transfer it to the movable connecting pin 312. This provides a buffer for the force on the movable connecting pin 312, preventing the movable connecting pin 312 from being impacted by the force and causing the suction cup 311 to apply a large force to the wall panel 100, thus avoiding increased deformation. This ensures that the wall panel 100 is controlled and does not deform during the process of being supported and moving. Furthermore, the compression spring 315 can buffer the force on the wall panel 100 compared to the hard force in related technologies.

[0031] When the linear motion component 35 applies a constant force to the movable connecting pin 312, the movable connecting pin 312 is always subjected to a tensile force, thus exerting a force away from the suction cup 311. To ensure a constant force and prevent the movable connecting pin 312 from disengaging from the suction cup 311 due to relative movement, the movable connecting pin 312 is further provided with a limiting part 3121, which can abut against the end of the compression sleeve 316. The compression sleeve 316 then applies an opposite force to the limiting part 3121, thereby keeping the position of the movable connecting pin 312 constant, thus achieving the purpose of controlling the shape of various parts of the wall panel 100.

[0032] Furthermore, the suction cup 311 moves in a straight line. Due to the high deformation precision of the wall panel 100, if the suction cup 311 vibrates or deviates from its predetermined path when acting on the wall panel 100, the wall panel 100 may deform and fail to fit snugly against the wing frame. Therefore, the shaping structure 3 also includes a guide assembly 4, which is connected to the transmission component 34 to guide it. The guide assembly 4 guides the transmission component 34 to ensure stable movement. Stable movement of the transmission component 34 drives the suction cup 311 to move stably, thus preventing vibration of the suction cup 311 during movement and ensuring that the wall panel 100 does not deform.

[0033] Furthermore, the guide assembly 4 and the transmission component 34 work together to control the movement of the suction cup 311 in the normal direction of the wall panel 100, that is, the suction cup 311 is always perpendicular to the wall panel 100, regardless of the shape of the wall panel 100.

[0034] In some embodiments, the wingplate shaping device further includes a support 5, which is fixed to the shape plate 2, and the guide assembly 4 includes a slide rail and a slider, with the slide rail fixed to the support 5 and the slider connected to the transmission component 34.

[0035] Support 5 provides support for the guide assembly to ensure that the slide rail is in a horizontal state. The combination of the slide rail and the slider enables the transmission component 34 to move smoothly along the length extension direction of the slide rail.

[0036] In addition, the drive component 32 is also fixed to the support 5. With this arrangement, during assembly, the drive component 32, the guide component 4 and the adsorption component 31 can be assembled and installed on the support 5 first, and then the support 5 can be installed as a whole on the outer profile plate 2, which can improve assembly efficiency.

[0037] In addition, the support 5 is provided with a support frame 51, which is used to support the compression sleeve 316. The compression sleeve 316 is raised by the support frame 51 to ensure that the suction cup 311 is completely adsorbed on the wall panel 100. Furthermore, the support frame 51 can also make the position of the wall panel 100 adsorbed by the suction cup 311 different, so as to meet the shape control requirements of different positions of the wall panel 100.

[0038] The movable connecting pin 312 is directly connected to the suction cup 311. This would cause the suction cup 311 to rotate when the movable connecting pin 312 rotates, resulting in deformation of the wall panel 100. Therefore, in some embodiments, the shaping structure 3 also includes a straight bushing 317 and a guide pin 318. The straight bushing 317 is sleeved on the outer periphery of the movable connecting pin 312 and embedded in the compression sleeve 316. The guide pin 318 is inserted into both the movable connecting pin 312 and the compression sleeve 316.

[0039] The linear bushing 317 and guide pin 318 prevent the movable connecting pin 312 from rotating relative to the compression copper sleeve during operation, and prevent the suction cup 311 from rotating with the movable connecting pin 312 and causing deformation of the wall panel 100. This improves the device's control over the shape of the wall panel 100.

[0040] Specifically, the end of the compression sleeve 316 facing the movable connecting pin 312 is provided with an installation groove, and the linear bushing 317 is embedded in the installation groove.

[0041] The linear bushing 317 provides high-precision linear guidance. To this end, the linear bushing 317 enables the movable connecting pin 312 to move linearly, and the linear bushing 317 is embedded in the mounting groove to prevent the linear bushing 317 from moving.

[0042] The linear motion assembly 35 includes a lead screw and a nut, which are screwed together. The lead screw is connected to the drive member 32 via a coupling 36. The lead screw can move the nut linearly under the drive of the drive member 32. The nut is connected to the transmission member 34 to drive the transmission member 34 to move linearly.

[0043] For example, the drive component 32 is a servo motor. The force monitoring component 33 is a pressure sensor used to monitor thrust and tension.

[0044] For example, the transmission component 34 is a transmission plate, and the nut and the adsorption assembly 31 are located on the same side of the transmission plate and are both connected to the transmission plate. In this way, the transmission plate can transmit the movement of the nut to the adsorption assembly 31, so that the adsorption assembly 31 can move.

[0045] Continue to refer to Figure 1 In some embodiments, the main frame 1 has lifting lugs 11 at its corners, which facilitate fixing the main frame 1 to the hook of the overhead crane for easy movement. Additionally, positioning plates 12 are provided at the corners of the main frame 1 to position the main frame 1 against the wing frame, facilitating alignment of the wall panel 100 with the wing frame. The main frame 1 employs a lightweight design to reduce the overall weight of the wing panel control device.

[0046] During installation, the drive component 32, force monitoring component 33, transmission component 34, guide component 4 and adsorption component 31 are first assembled and installed on the support 5. Then, the support 5 is fixed as a whole to the side of the outer shape plate 2. The outer shape plate 2 is set vertically relative to the wall panel 100, and the shaping structures 3 on the same outer shape plate 2 are set at intervals. The interval distance is set according to the actual shape control position of the wall panel 100. Then, the outer shape plate 2 is fixed to the main frame 1.

[0047] Of course, in other embodiments, the outer shape plate 2 can be fixed to the main frame 1 first, and then the shaping structure 3 can be fixed to the outer shape plate 2 according to actual needs.

[0048] When the wing panel shaping device is working, the suction component 31 is controlled by the drive component 32 to extend its distance. The direction of movement is controlled by the transmission component 34 and the guide component 4 to be the same as the normal direction of the wing panel 100. The force monitoring component 33 can monitor the tension and thrust forces acting on the wing panel 100 in real time. By controlling the drive component 32 to provide tension (push) force to the wing panel 100, the force monitoring component 33 detects the tension (push) force limit value, and the drive component 32 stops moving, thus providing continuous tension (push) force to maintain the shape of the wing panel 100. The tension force is achieved through the tension spring 313 to flexibly stretch the wing panel 100, and the thrust force is applied to the wing panel 100 through the compression spring 315. The movable connecting pin 312 is used to connect the suction cup 311 and the tension spring 313. After the wall panel 100 is mounted on the device, the drive unit 32 moves the wall panel 100 away from it. The tension spring 313 inside the tension sleeve 314 applies tension to the movable connecting pin 312, thereby generating a tension value on the wall panel 100, causing the wall panel 100 to conform to the outer shape clamp 2. Before transporting to the wing assembly station, if the power is disconnected, the drive unit 32 has a power-off brake function, which can maintain the tension effect on the wall panel 100 while maintaining the air source suction force of the suction cup 311. At the assembly station, the drive unit 32 moves towards the wall panel 100, and the tension sleeve 314 applies a pushing force to the retaining ring 319 on the movable connecting pin 312 through the compression spring 315, thereby applying a pushing force to the wall panel 100 so that the wall panel 100 can be properly assembled with the wing rib. The guide pin 318 prevents the movable connecting pin 312 from rotating and cooperates with the linear bushing 317 to ensure that the suction cup 311 can only move in a fixed direction.

[0049] The force monitoring component 33 and the drive component 32 form a closed-loop system. When the tension or thrust exceeds the alarm value, the drive component 32 stops moving to protect the product. The suction cup 311 should be positioned to avoid the area where the wall panel 100 connects to the wing rib, thus avoiding the drilling area.

[0050] (1) The wing panel 100 is mounted on the frame, and the suction cup 311 provides suction to fix the panel 100.

[0051] (2) The driving component 32 drives the linear movement component 35, which in turn drives the adsorption component 31 and the force monitoring component 33 to monitor until the outer surface of all the wall panels 100 fits the theoretical surface of the card plate.

[0052] (3) Transport the wing panel control device to the wing assembly station, drive the drive component 32, change the tension of the wing panel 100 to the thrust according to the assembly status of the panel 100, coordinate the gap value between the panel 100 and the wing rib, and complete the assembly of the panel 100.

[0053] The wingplate shape control device has the following advantages: The pulling and pushing forces of each suction cup 311 are controllable. It can provide stronger pulling forces to the areas of the wall panel 100 with large deformation and weaker pulling forces to the areas of the wall panel 100 with small deformation, effectively controlling the shape of the large wall panel 100 to the theoretical position.

[0054] The force monitoring component 33 can monitor the pulling and pushing forces of each suction cup 311 and generate data reports for the control and research of the wall panel 100.

[0055] The main frame 1 adopts a lightweight design, and the frame is matched with the shape of the large wall panel 100, which can meet the installation requirements of the card plate 2 in different positions.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
