Description

Technical Field

[0001] This utility model relates to the field of wall panel production technology, and in particular to a flexible buffer positioning mechanism for a wall panel flipping device. Background Technology

[0002] Against the backdrop of rapid development in building industrialization and prefabricated construction, wall panels, as an important component of building structures, are seeing increasingly higher levels of automation in their production and installation. Wall panel turning equipment, as a key piece of equipment for achieving efficient wall panel production, is mainly used to complete the posture transformation of wall panels during the production process (such as switching between horizontal and vertical states) to meet the requirements of subsequent processes such as pouring, curing, transportation, and installation.

[0003] Currently, most common wall panel flipping devices on the market use rigid mechanical structures to achieve the positioning and flipping of wall panels. These devices have revealed the following technical bottlenecks in practical applications:

[0004] In traditional rigid positioning mechanisms, the wall panel and positioning components come into direct, rigid contact during the flipping process, which generates a large impact force. This can easily lead to quality defects such as cracks and edge damage on the wall panel surface, and the damage is particularly significant for high-precision, thin-walled wall panel components.

[0005] Rigid structures lack self-adjustment capabilities. When there are tolerances in the dimensions of the wall panels or fluctuations in the turning speed, the positioning error will be amplified, making it difficult for the accuracy of subsequent processes (such as the installation of embedded parts and joint treatment) to meet the high standards required for prefabricated buildings.

[0006] Different specifications and materials of wall panels (such as concrete wall panels and lightweight composite wall panels) have different requirements for cushioning and positioning. Traditional rigid mechanisms are difficult to achieve compatible processing of multiple types of wall panels, which limits the application range of the equipment. Utility Model Content

[0007] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of poor adaptability of the positioning mechanism. To this end, we propose a flexible buffer positioning mechanism for a wall panel flipping device.

[0008] To achieve the above objectives, this application adopts the following technical solution: a flexible buffer positioning mechanism for a wall panel flipping device, comprising a worktable, a guide rail mounted on the top of the worktable, and support seats mounted at both ends of the guide rail. A fixed positioning plate is rotatably connected to the top of one support seat, and a motion positioning plate is provided on the top of the other support seat. A servo motor is provided on the side of the motion positioning plate away from the fixed positioning plate, and a control component is provided at the output end of the servo motor. The control component includes an assembly cylinder, a movable stage built into the assembly cylinder, multiple return springs provided on the side of the movable stage near the bottom of the inner cavity of the assembly cylinder, a contact rod provided on the side of the movable stage near the bottom of the inner cavity of the assembly cylinder, a pressure sensor provided at the end of the contact rod away from the movable stage, a fixed roller fixedly connected to the side of the movable stage away from the pressure sensor, and a motion positioning plate fixedly connected to the end of the fixed roller away from the movable stage. An oil pipe is fixedly connected to one side of the assembly cylinder.

[0009] Preferably, the movable platform has a fixing ring groove around its perimeter, and a sealing ring is fitted inside the fixing ring groove.

[0010] Preferably, one end of the reset spring is fitted with a positioning cylinder, and one end of the positioning cylinder is fixedly connected to the bottom of the inner cavity of the assembly cylinder.

[0011] Preferably, the moving platform has multiple positioning slots on one side, and one end of the reset spring is fixedly connected to the bottom of the positioning slot cavity.

[0012] Preferably, a telescopic rod is provided between the two support seats, and one end of the assembly cylinder is fixedly connected to the output end of the servo motor.

[0013] Preferably, a fixing seat is sleeved and fixed on the surface of the pressure sensor, and one end of the fixing seat is fixedly connected to the bottom of the inner cavity of the assembly cylinder.

[0014] Preferably, the moving platform has a mounting groove on the side near the pressure sensor, and a telescopic spring is built into the mounting groove. The end of the telescopic spring away from the moving platform is fixedly connected to the contact rod.

[0015] Preferably, the oil pipe output end is located between the moving platform and the bottom of the assembly cylinder cavity.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This utility model features a flexible buffer positioning mechanism for a wall panel flipping device. Through structural design and intelligent control, it achieves precise positioning and efficient protection of the wall panels. A stable frame is constructed from the worktable guide rail and support base. The adjustable spacing of the telescopic rods adapts to different wall panel specifications. The fixed positioning plate and the moving positioning plate work together to position the wall panel. A servo motor drives the assembly cylinder, which in turn moves the moving table to adjust the angle of the moving positioning plate. Sealing rings around the moving table ensure the sealing of the assembly cylinder. The return spring compresses when pressure is applied to the wall panel, transferring the buffer force to the moving positioning plate to prevent hard contact. In the pressure sensing system, the contact rod and pressure sensor provide real-time pressure signal feedback. The control system adjusts the oil injection volume in the oil pipe accordingly to precisely control the contact pressure.

[0018] Rubber pads on the panel surface, a return spring, and hydraulic pressure regulation effectively buffer impact forces, preventing damage to the wall panel surface and improving finished product quality. A pressure sensor, linked to a servo motor and hydraulic lines, automatically adapts to fluctuations in wall panel dimensional tolerances and flipping speed, ensuring positioning accuracy and meeting the high standards of prefabricated buildings. By adjusting the return spring parameters, regulating the hydraulic pressure range, and controlling the servo motor speed and angle, the system is compatible with various wall panels, including concrete and lightweight composite materials, broadening the equipment's application scenarios and providing reliable support for wall panel production and processing.

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Reference Figures 1 to 6 As shown, this utility model provides a technical solution: a flexible buffer positioning mechanism for a wall panel flipping device, including a worktable 1. A guide rail 101 is installed on the top of the worktable 1. Support seats 2 are installed at both ends of the guide rail 101. A telescopic rod 201 is provided between the two support seats 2. A fixed positioning plate 3 is rotatably connected to the top of one support seat 2, and a motion positioning plate 301 is provided on the top of the other support seat 2. A servo motor 302 is provided on the side of the motion positioning plate 301 away from the fixed positioning plate 3. A control component 4 is provided at the output end of the servo motor 302. The guide rail 101 on the top of the worktable 1 provides stable support and a motion track for the entire positioning mechanism. The two support seats 2 are installed at both ends of the guide rail 101, forming the basic framework of the mechanism. The telescopic rod 201 is located between the two support seats 2, and the distance between the support seats 2 can be adjusted according to actual needs to adapt to the flipping and positioning of wall panels of different specifications. The fixed positioning plate 3, which is rotatably connected to the top of the support base 2 on one side, provides a fixed positioning reference for one side of the wall panel. The moving positioning plate 301 on the top of the support base 2 on the other side is driven by the servo motor 302 and the control component 4 to adjust the position and pressure, thereby completing the flexible buffer positioning of the other side of the wall panel.

[0029] Furthermore, the control component 4 includes an assembly cylinder 401. One end of the assembly cylinder 401 is fixedly connected to the output end of the servo motor 302. The assembly cylinder 401 contains a movable stage 402. The movable stage 402 has fixing annular grooves 403 around its perimeter. A sealing ring 404 is fitted inside the fixing annular grooves 403. Multiple return springs 405 are provided on the side of the movable stage 402 near the bottom of the inner cavity of the assembly cylinder 401. One end of each return spring 405 is fitted with a positioning cylinder 406. One end of the positioning cylinder 406 is fixed to the inner cavity of the assembly cylinder 401. The bottom of the cavity is fixedly connected, and multiple positioning slots 407 are opened on one side of the moving stage 402. One end of the return spring 405 is fixedly connected to the bottom of the inner cavity of the positioning slot 407. The servo motor 302 serves as a power source, and its output end is fixedly connected to the assembly cylinder 401. When the servo motor 302 is started, it can drive the assembly cylinder 401 to rotate, and then transmit the power to the motion positioning plate 301 through the moving stage 402 inside the assembly cylinder 401, so as to realize the rotation of the motion positioning plate 301 to adapt to the angle adjustment during the wall panel flipping process. Inside the assembly cylinder 401, the moving stage 402 has fixed ring grooves 403 around its perimeter, and the built-in sealing ring 404 ensures the sealing of the inside of the assembly cylinder 401, creating conditions for subsequent oil injection and pressure control. Multiple return springs 405 are provided on the side of the moving stage 402 near the bottom of the inner cavity of the assembly cylinder 401. One end of the return spring 405 is sleeved and fixed on the positioning cylinder 406, which is fixedly connected to the bottom of the inner cavity of the assembly cylinder 401. The other end is fixedly connected to the bottom of the inner cavity of the positioning groove 407 opened on one side of the moving stage 402. When the moving positioning plate 301 is subjected to pressure from the wall panel, the pressure is transmitted to the moving stage 402 through the fixed roller 413. The moving stage 402 moves in the assembly cylinder 401 towards the bottom of the inner cavity of the assembly cylinder 401, compressing the return springs 405. The buffering force generated by the return springs 405 is transmitted to the moving positioning plate 301 through the moving stage 402 and the fixed roller 413, so that the moving positioning plate 301 and the wall panel form a flexible contact, avoiding hard impact.

[0030] Furthermore, a contact rod 408 is provided on the side of the moving stage 402 near the bottom of the inner cavity of the assembly cylinder 401. A pressure sensor 411 is provided at the end of the contact rod 408 away from the moving stage 402. An installation groove 409 is provided on the side of the moving stage 402 near the pressure sensor 411. A telescopic spring 410 is built into the installation groove 409. The end of the telescopic spring 410 away from the moving stage 402 is fixedly connected to the contact rod 408. A fixed roller 413 is fixedly connected to the side of the moving stage 402 away from the pressure sensor 411. The end of the fixed roller 413 away from the moving stage 402 is fixedly connected to the motion positioning plate 301. A fixed seat 412 is sleeved and fixedly fixed on the surface of the pressure sensor 411. One end of the fixed seat 412 is fixedly connected to the bottom of the inner cavity of the assembly cylinder 401. An oil pipe 414 is fixedly connected to one side of the assembly cylinder 401. The output end of the oil pipe 414 is located between the moving stage 402 and the bottom of the inner cavity of the assembly cylinder 401. The pressure sensing and adjustment system plays a key feedback control role in the entire working process. A contact rod 408, located on the side of the moving stage 402 near the bottom of the inner cavity of the assembly cylinder 401, remains in contact with the pressure sensor 411 under the action of the telescopic spring 410. When the moving stage 402 is subjected to pressure, the contact rod 408 moves accordingly and transmits the pressure to the pressure sensor 411. The pressure sensor 411 converts the pressure signal into an electrical signal and feeds it back to the control system. The control system, based on a preset pressure threshold and the specific parameters of the wall panel, controls the oil pipe 414 to inject or discharge oil into the assembly cylinder 401, adjusting the oil pressure between the moving stage 402 and the bottom of the inner cavity of the assembly cylinder 401. This further adjusts the position of the moving stage 402 and the compression of the return spring 405, achieving precise control of the overall contact pressure. For example, when excessive pressure is detected, the control system controls the oil pipe 414 to discharge some oil, reducing the internal pressure and causing the moving stage 402 to move back appropriately under the action of the return spring 405, reducing the pressure on the wall panel; when the pressure is too low, oil is injected to increase the pressure and ensure the stability of the positioning.

[0031] To prevent damage to the wall panel, the mechanism incorporates rubber pads on the surfaces of the two positioning plates. These rubber pads possess excellent elasticity and can absorb some of the impact force. Simultaneously, the buffering force provided by the return spring 405 and the control of contact pressure by the hydraulic pipe 414 ensure a flexible contact between the moving positioning plate 301 and the wall panel, preventing hard impacts. When the wall panel contacts the positioning plate, the compression of the return spring 405 and the adjustment of the hydraulic pressure effectively buffer the impact force, distributing it evenly across the wall panel surface and reducing localized stress concentration. This protects the wall panel surface from damage, significantly improving the finished quality of the wall panel, and is particularly suitable for the flipping and positioning of high-precision, thin-walled wall panel components.

[0032] Regarding adaptive adjustment capabilities, the pressure sensor 411 in control component 4 senses changes in contact pressure in real time. Combined with the precise control of servo motor 302 and oil pipe 414, the position and contact pressure of the motion positioning plate 301 can be automatically adjusted according to the tolerance of the wall panel size and fluctuations in the flipping speed. For example, when there is a certain tolerance in the wall panel size, the motion positioning plate 301 can be appropriately adjusted under the drive of servo motor 302. At the same time, the positioning pressure is kept stable by adjusting the return spring 405 and the hydraulic pressure, thereby reducing positioning errors. When the flipping speed fluctuates, the pressure sensor 411 can detect changes in impact force in a timely manner and adjust the hydraulic pressure and the rotation speed of servo motor 302 through the control system. This allows the positioning mechanism to quickly adapt to speed changes and maintain positioning accuracy, providing a reliable foundation for subsequent processes such as embedded part installation and joint treatment, and meeting the high standards required for prefabricated buildings.

[0033] Regarding the compatibility of various wall panel types, wall panels of different specifications and materials (such as concrete wall panels and lightweight composite wall panels) have different requirements for cushioning and positioning. The device achieves compatibility for various wall panel types through the following design: First, the elastic coefficient and number of return springs 405 can be adjusted according to the material and weight of the wall panel. For heavier concrete wall panels, return springs 405 with a larger elastic coefficient or an increased number of springs can be selected to provide sufficient cushioning force; for lightweight composite wall panels, springs with a smaller elastic coefficient or a reduced number of springs can be selected to avoid excessive cushioning force causing damage to the wall panel. Second, the pressure control range of the oil pipe 414 is wide, and the contact pressure can be precisely adjusted according to the requirements of different wall panels to ensure stable positioning under appropriate pressure for both rigid concrete wall panels and flexible lightweight composite wall panels. Third, the speed and rotation angle of the servo motor 302 can be flexibly adjusted through the control system to adapt to the angle and position requirements during the flipping process of wall panels of different specifications. In summary, this mechanism can flexibly adjust the buffering and positioning parameters according to the specific type and requirements of the wall panel, greatly improving the application range of the equipment and enabling it to play a good role in the production and processing of various wall panels.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
