Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade manufacturing equipment technology, and in particular to a laser projection positioning system for fiberglass cloth layer laying operation of wind turbine blades. Background Technology

[0002] In modern large-scale equipment manufacturing, especially in fields such as wind power and aerospace, the application of composite material components is becoming increasingly widespread. Taking the manufacturing of wind turbine blades as an example, it typically requires laying large amounts of fiberglass or carbon fiber cloth layer by layer onto a huge mold according to extremely precise predetermined contours and sequences. To replace the traditional, inefficient, and error-prone physical templates, laser projection technology has been introduced into the layup-aid process. This technology uses a high-precision laser projector to directly and clearly project the digital contour lines from the design software onto the mold surface, providing operators with real-time and accurate layup guidance. This non-contact, flexible template technology greatly improves production efficiency and product quality consistency. Therefore, how to stably and accurately install the laser projector above the work area of ​​a large production workshop and ensure its long-term reliable operation is a key prerequisite for the successful application of this technology.

[0003] To achieve this laser projection positioning, various installation devices have been disclosed in the prior art. For example, Chinese Utility Model Patent Publication No. CN 219202724 U discloses a laser projection-assisted layering device. The technical solution of this device mainly includes a factory beam, a fixing plate, a fixing shaft, and a laser emitting mechanism. Its core structure lies in suspending a fixing shaft below the factory beam through the fixing plate, and then fixing the laser emitting mechanism to the fixing shaft through a laser fixing sleeve, thereby fixing the laser projector above the working area.

[0004] However, after in-depth research and practice of the aforementioned prior art, those skilled in the art have discovered that this purely rigid fixed structure has inherent defects that are difficult to overcome in actual industrial production environments. Firstly, large manufacturing workshops, especially those involved in wind turbine blade production, experience continuous and complex structural vibrations due to factors such as large overhead cranes lifting heavy objects, the start-up and shutdown of surrounding large equipment, and even the passage of heavy vehicles outside the workshop. In the scheme of CN 219202724 U, since the fixed plate and the workshop beam, the fixed shaft and the fixed plate, and the laser fixing sleeve and the fixed shaft are all rigidly connected, this structure effectively constitutes a vibration transmission path without attenuation. Any minute vibration originating from the workshop structure will be directly and completely transmitted to the laser emitting mechanism, causing it to generate high-frequency jitter. This jitter ultimately manifests as the projected laser outline becoming blurred, flickering, or producing "ghosting," severely affecting the visual judgment of the layup workers, reducing layup accuracy and work efficiency, and may even lead to substandard product quality.

[0005] Furthermore, this rigid fixed structure cannot cope with the long-term, slow macroscopic displacement caused by factors such as thermal expansion and contraction of the factory structure due to temperature changes, or uneven settlement of the foundation. Once the installation and commissioning are completed, the absolute spatial coordinates of the laser projector are completely fixed. Over time, the factory beams serving as the installation reference will experience millimeter-level displacement, causing the entire device to shift accordingly, without any ability to sense or compensate for this shift. This will cause the projection reference to gradually deviate from the theoretically designed position. To ensure product quality, technicians must periodically interrupt production to perform tedious remeasurement and calibration of the device, which not only consumes a significant amount of production time but also increases labor costs and introduces the risk of human error.

[0006] In summary, existing rigid and passive installation structures, due to their inability to actively isolate vibration and compensate for displacement, suffer from technical problems such as unstable positioning accuracy and the need for frequent manual intervention in complex industrial environments. These issues make it difficult to meet the stringent requirements of modern large-scale, high-precision composite material manufacturing for production efficiency and quality stability. Utility Model Content

[0007] The purpose of this invention is to provide a laser projection positioning system for the installation of fiberglass cloth layers on wind turbine blades, in order to solve the technical problems in the prior art where the positioning accuracy is easily affected by vibration and the position drift cannot be automatically compensated due to the use of a purely rigid fixed structure.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A laser projection positioning system for fiberglass cloth layer paving operations on wind turbine blades includes: a two-dimensional displacement mechanism; a damping assembly installed below the two-dimensional displacement mechanism and used to mount a laser projector; a sensing component including a first displacement sensor and a second attitude sensor; and a central control system platform; wherein the damping assembly includes multiple metal plates and multiple elastic rubber pads stacked alternately in a vertical direction, and at least one electromagnetic hydraulic damping adjuster; and the central control system platform is electrically connected to the sensing component, the two-dimensional displacement mechanism, and the electromagnetic hydraulic damping adjuster, and configured to control the two-dimensional displacement mechanism to perform displacement compensation based on the displacement or attitude signal detected by the sensing component, and to control the electromagnetic hydraulic damping adjuster (7) to adjust the damping force to actively suppress vibration and compensate for displacement.

[0010] This technical solution fundamentally changes the passive, fixed mode of existing technologies by constructing a complete closed-loop control system integrating "perception-decision-execution". Specifically, the multi-layered composite structure in the vibration damping assembly, combined with the active damping regulator, effectively isolates and suppresses vibrations from external sources. Simultaneously, sensing components monitor the system's position and attitude changes in real time, and the central control system platform drives a two-dimensional displacement mechanism for active compensation based on the monitoring data. This structural design enables the system to actively combat vibration interference and position drift, providing an extremely stable working platform for the laser projector, thereby ensuring long-term, high-precision stability of projection positioning.

[0011] Preferably, the two-dimensional displacement mechanism includes an X-axis electric lead screw mechanism and a Y-axis electric lead screw mechanism. The X-axis electric lead screw mechanism is a cuboid frame arranged in the horizontal direction, which is suspended below a factory beam. The Y-axis electric lead screw mechanism is also a cuboid frame, which is installed below the X-axis electric lead screw mechanism, and the length direction of the Y-axis electric lead screw mechanism is perpendicular to the length direction of the X-axis electric lead screw mechanism.

[0012] This structure ingeniously constructs a suspended Cartesian coordinate positioning system through two mutually orthogonal lead screw mechanisms. This orthogonal layout is the structural foundation for achieving precise compensation at any point in the plane, providing the system with a wide range of physical movement capabilities. Simultaneously, its installation method, suspended from the factory's overhead beams, not only makes full use of the upper space of the workshop but also provides a broad and unobstructed working field of view for the laser projector below, ensuring it can cover the entire working area of ​​large workpieces.

[0013] Preferably, the plurality of metal plates and plurality of elastic rubber pads of the shock absorption assembly are arranged from top to bottom as follows: a base metal plate, a first elastic rubber pad, a middle metal plate, a second elastic rubber pad, an outer metal plate and a third elastic rubber pad; the thickness of the third elastic rubber pad is greater than the thickness of the second elastic rubber pad, and the thickness of the second elastic rubber pad is greater than the thickness of the first elastic rubber pad (4).

[0014] The core of this structure lies in the construction of a highly efficient passive mechanical filter through the alternating layering of rigid metal plates and flexible rubber pads with gradient thicknesses (and varying hardness). The rigid metal plates act as mass blocks, while the flexible rubber pads function as springs and dampers, forming multiple series-connected "mass-spring-damper" units. Vibrations passing through this structure are reflected and absorbed at the interfaces of each different material. More importantly, through the gradient thickness design, different layers of units exhibit different responses to vibrations at different frequencies, thus achieving layered and efficient attenuation of vibrations over a wide frequency range. This provides a preliminary yet highly effective foundation for subsequent active vibration damping.

[0015] Preferably, there are multiple electromagnetic hydraulic damping adjusters, which are cylindrical and vertically positioned below the outer metal plate, and are evenly distributed around the installation position of the laser projector.

[0016] This structure, based on a highly efficient passive damping structure, further incorporates active damping elements, forming a composite damping system that combines active and passive damping. Multiple cylindrical damping adjusters are evenly distributed at the ends of the passive damping structure, enabling real-time adjustment of the damping force by changing the viscosity of the internal magnetorheological fluid according to instructions from the central control system platform. This structure can actively and rapidly suppress sudden impacts and residual vibrations that are difficult for passive damping systems to eliminate, thereby achieving ultimate stability control of the laser projector's attitude.

[0017] Preferably, the first displacement sensor is a small rectangular block that is mounted on the X-axis electric lead screw mechanism; the second attitude sensor is also a small rectangular block that is mounted on the outer metal plate of the shock absorption assembly and adjacent to the mounting position of the electromagnetic hydraulic damping adjuster.

[0018] This structure, through a clever sensor layout, achieves precise, separate measurement of two different types of disturbances. The first displacement sensor is mounted at the top of the system's moving frame, directly measuring the macroscopic positional drift of the entire system relative to a fixed reference (the factory building's crossbeam). The second attitude sensor is installed at the end of the damping assembly, adjacent to the protected laser projector, measuring the microscopic attitude jitter of the laser projector after damping. This separate layout avoids signal coupling, providing a clear, decoupled control input to the central control system platform, and is the structural foundation and prerequisite for achieving precise compensation and intelligent damping.

[0019] Preferably, it also includes a layup monitoring component, which includes at least one top camera mounted on the crossbeam of the plant and facing downwards, and multiple side cameras respectively located on both sides of a wind turbine blade main mold and facing the main mold.

[0020] This structure leverages the system's inherent high stability to expand its functionality from simple positioning to process monitoring. By placing cameras above the system and on both sides of the workpiece, a multi-view, three-dimensional monitoring network is constructed. This structure completely eliminates blind spots caused by the curved surface of the mold or operator obstruction, ensuring not only the accuracy of laser projection but also comprehensive quality monitoring of the layering process based on this projection. This elevates the system from a simple positioning tool into a comprehensive production support system integrating positioning and process quality inspection.

[0021] Preferably, the central control system platform is a vertical cabinet-like structure with a display screen and an operating console, and the layered monitoring component also includes an audible and visual alarm device in the shape of a multi-layered cylindrical tower installed on the top of the central control system platform.

[0022] This structure defines a centralized and efficient human-machine interface for the entire complex system. The display screen and control panel are integrated into a vertical cabinet, with a prominent tower-shaped audible and visual alarm placed on top, forming an ergonomic workstation. This structure allows operators to intuitively access all monitoring screens and system statuses from a single location and receive clear alarm signals, greatly improving system operability, information transmission efficiency, and production safety.

[0023] In summary, this invention organically combines a two-dimensional displacement mechanism, a multi-stage composite damping structure, high-precision sensing components, and a central control platform to construct an intelligent closed-loop system capable of actively combating vibration and automatically compensating for displacement. This system fundamentally solves the problems of instability in accuracy and the need for frequent manual intervention caused by rigid installation in existing technologies, significantly improving the stability and automation level of laser projection positioning.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 This utility model provides a laser projection positioning system for the installation of fiberglass cloth layers on wind turbine blades, aiming to solve the technical problems in the prior art where the positioning accuracy is easily affected by vibration and the position drift cannot be automatically compensated due to the use of a purely rigid fixed structure.

[0027] This embodiment provides a laser projection positioning system for fiberglass cloth layer installation on wind turbine blades, comprising: a two-dimensional displacement mechanism; a damping assembly mounted below the two-dimensional displacement mechanism and used to mount a laser projector 15; a sensing component including a first displacement sensor 13 and a second attitude sensor 11; and a central control system platform 24. The damping assembly includes multiple metal plates 8, 9, 10 and multiple elastic rubber pads 4, 5, 6 stacked alternately in a vertical direction, and at least one electromagnetic hydraulic damping adjuster 7. The central control system platform 24 is electrically connected to the sensing component, the two-dimensional displacement mechanism, and the electromagnetic hydraulic damping adjuster 7. It is configured to control the two-dimensional displacement mechanism to perform displacement compensation based on the displacement or attitude signal detected by the sensing component, and to control the electromagnetic hydraulic damping adjuster 7 to adjust the damping force to actively suppress vibration and compensate for displacement.

This structural design enables the system to actively combat vibration interference and position drift, providing an extremely stable working platform for the laser projector 15, thereby ensuring long-term, high-precision stability of projection positioning.

[0029] Furthermore, the two-dimensional displacement mechanism includes an X-axis electric lead screw mechanism 2 and a Y-axis electric lead screw mechanism 3. The X-axis electric lead screw mechanism 2 is a cuboid frame arranged in the horizontal direction, which is suspended below a factory beam 1. The Y-axis electric lead screw mechanism 3 is also a cuboid frame, which is installed below the X-axis electric lead screw mechanism 2, and the length direction of the Y-axis electric lead screw mechanism 3 is perpendicular to the length direction of the X-axis electric lead screw mechanism 2.

[0030] This structure ingeniously constructs a suspended Cartesian coordinate positioning system through two mutually orthogonal lead screw mechanisms. This orthogonal layout is the structural foundation for achieving precise compensation at any point in the plane, providing the system with a wide range of physical movement capabilities. Simultaneously, its installation method, suspended from the overhead factory beam 1, not only makes full use of the upper space of the workshop but also provides a wide and unobstructed working field of view for the laser projector 15 below, ensuring that it can cover the entire working area of ​​the large workpiece.

[0031] Furthermore, the multiple metal plates and multiple elastic rubber pads of the shock absorption assembly are arranged from top to bottom as follows: a base metal plate 8, a first elastic rubber pad 4, a middle metal plate 9, a second elastic rubber pad 5, an outer metal plate 10, and a third elastic rubber pad 6; the thickness of the third elastic rubber pad 6 is greater than the thickness of the second elastic rubber pad 5, and the thickness of the second elastic rubber pad 5 is greater than the thickness of the first elastic rubber pad 4.

[0032] The core of this structure lies in the construction of a highly efficient passive mechanical filter through the alternating layering of rigid metal plates and flexible rubber pads with gradient thicknesses. The rigid metal plates act as mass blocks, while the flexible rubber pads function as springs and dampers, forming multiple series-connected "mass-spring-damper" units.

More importantly, through the gradient thickness design, different layers of units exhibit different responses to vibrations of different frequencies, thus achieving layered and efficient attenuation of vibrations over a wide frequency range. This provides a preliminary yet highly effective foundation for subsequent active vibration damping.

[0033] Furthermore, there are multiple electromagnetic hydraulic damping adjusters 7, which are cylindrical and are arranged vertically below the outer metal plate 10, and are evenly distributed around the installation position of the laser projector 15.

[0034] This structure, based on a highly efficient passive damping structure, further incorporates active damping elements, forming a composite damping system that combines active and passive damping. Multiple cylindrical damping adjusters 7 are evenly distributed at the ends of the passive damping structure, enabling real-time adjustment of the damping force by changing the viscosity of the internal magnetorheological fluid according to instructions from the central control system platform 24. This structure can actively and rapidly suppress sudden impacts and residual vibrations that are difficult for passive damping systems to eliminate, thereby achieving ultimate stability control of the laser projector 15's attitude.

[0035] Furthermore, the first displacement sensor 13 is a small rectangular block, which is mounted on the X-axis electric lead screw mechanism 2; the second attitude sensor 11 is also a small rectangular block, which is mounted on the outer metal plate 10 in the shock absorption assembly and adjacent to the installation position of the electromagnetic hydraulic damping adjuster 7.

[0036] This structure, through a clever sensor layout, achieves precise, separate measurement of two different types of disturbances. The first displacement sensor 13 is mounted at the top of the system's moving frame, directly measuring the macroscopic positional drift of the entire system relative to the fixed reference, the factory beam 1. The second attitude sensor 11 is mounted at the end of the damping assembly, adjacent to the protected laser projector 15, measuring the microscopic attitude jitter of the laser projector 15 after damping. This separate layout avoids signal coupling, providing a clear, decoupled control input to the central control system platform 24, and is the structural foundation and prerequisite for achieving precise compensation and intelligent damping.

[0037] Furthermore, the system also includes a layup monitoring component, which includes at least one top camera 16 installed on the factory beam 1 and facing downwards to shoot, and multiple side cameras 20 respectively set on both sides of a wind turbine blade main mold 25 and facing the main mold to shoot.

[0038] This structure leverages the system's inherent high stability to expand its functionality from simple positioning to process monitoring. By placing cameras 16 and 20 above the system and on both sides of the workpiece, a multi-view, three-dimensional monitoring network is constructed. This structure completely eliminates blind spots caused by the mold's curved surface or operator obstruction, ensuring not only the accuracy of laser projection but also comprehensive quality monitoring of the layering process based on this projection. This elevates the system from a simple positioning tool into a comprehensive production support system integrating positioning and process quality inspection.

[0039] Furthermore, the central control system platform 24 is a vertical cabinet-like structure with a display screen and an operating console, and the layered monitoring component also includes a multi-layered cylindrical tower-shaped audible and visual alarm 23 installed on the top of the central control system platform 24.

[0040] This structure defines a centralized and efficient human-machine interface for the entire complex system. The display screen and control panel are integrated into a vertical cabinet 24, with a prominent tower-shaped audible and visual alarm 23 placed on top, forming an ergonomic workstation. This structure allows operators to intuitively access all monitoring screens and system statuses from a single location and receive clear alarm signals, greatly improving system operability, information transmission efficiency, and production safety.

[0041] Specifically, in this embodiment, please refer again. Figure 1The entire laser projection positioning system is suspended below the factory beam 1 at the top of the production workshop. The X-axis electric lead screw mechanism 2 is arranged along the length of the factory beam 1, and its slider is equipped with the Y-axis electric lead screw mechanism 3. Together, they form a two-dimensional motion platform that can cover the entire area of ​​the main wind turbine blade mold 25 below. The entire damping assembly is rigidly connected to the Y-axis electric lead screw mechanism 3 below via its top base metal plate 8. The damping assembly is constructed from top to bottom by stacking the base metal plate 8, a first elastic rubber pad 4 with higher hardness and thinner thickness, a middle metal plate 9, a second elastic rubber pad 5 with moderate hardness and medium thickness, an outer metal plate 10, and a third elastic rubber pad 6 with lower hardness and the largest thickness. This gradient design allows the damping system to absorb vibrations of different frequencies in layers. The laser projector 15 is fixed to the bottom of the entire damping assembly via a mounting plate (not shown), thus receiving maximum vibration isolation protection. Meanwhile, multiple electromagnetic hydraulic damping regulators 7 and 71 are evenly distributed circumferentially, with their two ends connected between the outer metal plate 10 and the mounting base of the laser projector, respectively, to actively suppress residual vibration.

[0042] In terms of sensing and control, the first displacement sensor 13 is installed between the stationary and moving parts of the X-axis electric screw mechanism 2 to monitor the absolute position drift of the system relative to the factory beam 1. The second attitude sensors 11 and 12 are attached to the outer metal plate 10 to capture the real-time attitude changes of the laser projector 15. The signal and power lines 21 of all sensors, actuators, cameras, and dampers are all connected to the transfer terminal cabinet 17 and filters / shields 18, 19, and 191 installed on the Y-axis electric screw mechanism 3 for processing and transfer, and then connected to the central control system platform 24 on the ground through the main cable bundle 22. The central control system platform 24 is a vertical cabinet integrating an industrial computer, display screen, and operating console, with a conspicuous audible and visual alarm 23 on its top. The layered monitoring components also include multiple top cameras 16 and 161 installed on the factory beam 1, and side cameras 20 and 201 installed on both sides of the main wind turbine blade mold 25 on the ground, which together form a comprehensive visual monitoring network. The entire system integrates vibration isolation, displacement compensation, and process monitoring through this structure, significantly improving the accuracy and automation level of laser-assisted layup for large workpieces.

[0043] The system's workflow and information interaction process are as follows: During system operation, the central control system main control signal processing module within the central control system platform 24 acts as the core, continuously executing closed-loop control. On one hand, it receives raw data from the sensing components, including macroscopic displacement data detected by the first displacement sensor 13 and microscopic attitude data detected by the second attitude sensor 11. This data first passes through an Ethernet interface to a Butterworth low-pass filter for preliminary filtering and high-frequency noise removal. Subsequently, the Kalman filter module performs state estimation and further processing on the filtered data to improve its accuracy and reliability. The processed high-precision state data is then sent to the adaptive algorithm module. This module optimizes and adjusts the algorithm parameters based on real-time dynamic data and outputs precise control signals. These control signals are divided into two paths: one drives a stepper motor, converting electrical energy into linear motion of the two-dimensional displacement mechanism, thereby providing physical position compensation for the system based on the lead screw's guidance; the other path uses a MEMS reflector control module to fine-tune the MEMS reflector inside the laser projector 15, achieving rapid and precise correction of the projection beam angle and position.

[0044] On the other hand, the top camera 16 and side cameras 20 in the layup monitoring component continuously collect image data of the work area and feed the images into the camera image data input module. The image comparison and analysis module compares and analyzes the real-time images with pre-stored standard images or models to detect abnormalities in the layup process. The analysis results, along with the sensor data, are fed into the main control signal processing module of the central control system. When a deviation or defect is detected, the main control signal processing module of the central control system makes a decision based on preset logic. On the one hand, it triggers the audible and visual alarm control module to activate the audible and visual alarm 23 to alert on-site personnel; on the other hand, it triggers the automatic error correction execution module to automatically adjust the projection compensation parameters according to the deviation, thereby achieving immediate correction of errors. Through the close coordination of the above structure and process, this utility model realizes a highly intelligent, adaptive laser projection positioning system with real-time quality inspection capabilities.

[0045] It should be noted that in the accompanying drawings of this utility model, in order to clearly indicate the existence of multiple identical or similar components, notation such as '7' and '71', '16' and '161', '19' and '191', '20' and '201' may be used. These notations all refer to the reuse of the same type of components (e.g., multiple electromagnetic hydraulic damping adjusters, multiple top cameras, etc.). In the description of the specification, for the sake of brevity, usually only one of the notations (such as '7', '16') is used as a representative for description, and the description also applies to other components of the same type.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the scope of implementation of the present utility model. All equivalent changes and modifications made in accordance with the scope defined by the claims of the present utility model shall still fall within the protection scope of the present utility model.
