Description

Technical Field

[0001] The utility model relates to the field of fan blade manufacturing, in particular to a fan blade web demoulding and flipping tool. Background Art

[0002] As a clean and renewable energy source, wind energy has developed rapidly around the world in recent years. Wind turbines are the core equipment of wind power generation, and wind blades are the key components of wind turbines to capture wind energy. The manufacturing process level directly affects the power generation efficiency and operating life of wind turbines.

[0003] Wind turbine blades are usually made of composite materials, and their structure mainly includes pressure surface shell, suction surface shell and web, etc. Among them, the web, as the main structure to bear the lateral shear load, is usually completed by prefabrication process, that is, the web is prefabricated first, and then bonded to the shell through bonding process to form an integral blade.

[0004] In the web prefabrication process, demoulding and flipping are two essential steps. Demolding refers to taking the prefabricated web out of the mold, and flipping refers to rotating the web 180° for subsequent processing or assembly. The traditional web demoulding and flipping process mainly relies on manual operation, which has problems such as low production efficiency, high labor intensity, and difficulty in ensuring product quality.

[0005] In order to overcome the above problems, some technical solutions have emerged in recent years to achieve automatic demoulding and flipping of webs. For example, Chinese patent document CN114772429A (hereinafter referred to as "Document 1") discloses a web demoulding and lifting tool and a demoulding and lifting method. The document provides a flippable positioning component, which realizes demoulding and lifting of the web by changing the state of the positioning component.

[0006] Specifically, the tooling of Document 1 includes a frame body, a plurality of suction components and a positioning component. The frame body is used to support the entire tooling; the suction component is arranged at the bottom of the frame body for adsorbing the web; the positioning component is arranged at both ends of the frame body and can be flipped, including horizontal and vertical states. When demolding is required, the positioning component is in a horizontal state to facilitate lifting the web out of the mold; when lifting is required, the positioning component is flipped to a vertical state to facilitate carrying the web to a designated position.

[0007] However, the solution in document 1 still has some shortcomings in practical applications, especially in the flipping of the positioning component:

[0008] The flipping operation is complicated and inefficient: Since the fan blade web is large in size and weighs hundreds or even thousands of kilograms, the size and weight of the positioning assembly also increase accordingly. In this case, if the flipping mechanism of the positioning assembly is not designed delicately, the flipping operation will be very complicated and require additional manual assistance to complete, which is time-consuming and labor-intensive, reducing production efficiency.

[0009] Positioning accuracy is difficult to ensure, affecting product quality: Large webs require high positioning accuracy. If the flipping mechanism of the positioning component is not accurate enough, the positioning component will not be able to accurately return to the predetermined position after flipping. This will lead to deviations in subsequent lifting and installation, affecting the bonding accuracy between the web and the shell, and ultimately affecting the manufacturing quality of the entire blade. Utility Model Content

[0010] The utility model provides a fan blade web demoulding and flipping tool, aiming to solve the problems of complex web demoulding and flipping operations and low efficiency in the prior art.

[0011] The utility model solves the above technical problems through the following technical solutions:

[0012] A fan blade web demoulding and flipping tool, comprising: a tool body, on which are provided a plurality of vacuum suction cups for adsorbing the web; a flipping mechanism, connected to the tool body, for driving the web to flip to a preset angle; a control system, electrically connected to the flipping mechanism, for controlling the flipping mechanism to drive the web to flip. Preferably, the flipping mechanism comprises: a drive motor, arranged on the tool body; a crankshaft, drivingly connected to the drive motor; an electric telescopic rod, connected to the crankshaft, for driving the web to flip. The structure is simple, the transmission is reliable, and the flipping of the web is easy to achieve.

[0013] Preferably, the crankshaft and the electric telescopic rod are connected by a connecting rod, so that the motion conversion is smooth, the flipping process is more controllable, and the stability of the flipping is improved.

[0014] Preferably, the control system controls the driving motor to drive the crankshaft to rotate, so that the electric telescopic rod is extended and retracted, thereby driving the web to flip, thereby realizing automatic control of the flipping process and improving production efficiency.

[0015] Preferably, the control system comprises an angle sensor for detecting the flipping angle of the web.

[0016] Preferably, the control system controls the start and stop of the drive motor according to the flip angle detected by the angle sensor, thereby achieving precise control of the flip angle of the web, ensuring that the web is flipped to a predetermined position, and improving product quality.

[0017] Preferably, the flip angle of the web is 180°. The specific application scenario targeted by the present invention, namely, the flipping requirement of the web of a fan blade is clarified.

[0018] Preferably, a supporting structure for supporting the web is also provided on the tooling body.

[0019] Preferably, the support structure includes a support plate and a plurality of support columns, wherein the support columns are arranged on the support plate, and the top ends of the support columns are provided with support surfaces that cooperate with the webs.

[0020] Preferably, the height of the support column is adjustable, which provides effective support to the web during the flipping process to prevent deformation, thereby further improving product quality.

[0021] In summary, the utility model can realize automatic flipping of the web by setting up a flipping mechanism and a control system without additionally operating a positioning component, thus solving the problem of complicated flipping operation and low efficiency in the prior art. At the same time, the control system's precise control of the flipping angle also ensures the accuracy of the web flipping, thus solving the problem of the prior art that the positioning accuracy is difficult to ensure and affects the product quality.

[0023] Figure 2 It is a schematic structural diagram of a fan blade web demoulding and flipping tooling after flipping 180° according to one embodiment of the utility model. DETAILED DESCRIPTION

[0024] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the structure of a fan blade web demoulding and flipping tooling according to an embodiment of the utility model. Figure 2 This is a schematic diagram of the structure of the fan blade web demoulding and flipping tooling after flipping 180° according to one embodiment of the utility model. Figure 1 and Figure 2 As shown, the embodiment of the utility model discloses a fan blade web demoulding and flipping tool, including a tool body 2, on which are provided a plurality of vacuum suction cups 3 for adsorbing the web. The plurality of vacuum suction cups 3 are evenly distributed on the bottom surface of the tool body 2, and are used to adsorb on the web so as to remove the web from a mold (not shown in the figure).

[0026] The demoulding turning tool also includes a turning mechanism for driving the web to turn over a preset angle. In this embodiment, the preset angle is 180°. The turning mechanism is connected to the tool body 2, and includes a drive motor 7 arranged on the tool body 2, a crankshaft 4 connected to the drive motor 7, and an electric telescopic rod 5 connected to the crankshaft 4 and used to drive the web to turn over. The crankshaft 4 and the electric telescopic rod 5 are connected by a connecting rod 10, and the two ends of the connecting rod 10 are respectively hinged to the crankshaft 4 and the electric telescopic rod 5, so that the rotational motion of the crankshaft 4 can be smoothly converted into the linear motion of the electric telescopic rod 5, thereby realizing the smooth turning over of the web, avoiding impact and vibration, and improving the stability of the turning process.

[0027] In addition, the demoulding and flipping tooling also includes a control system 6, which is electrically connected to the flipping mechanism and is used to control the flipping mechanism to drive the web to flip. In this embodiment, the control system 6 controls the drive motor 7 to drive the crankshaft 4 to rotate, so that the electric telescopic rod 5 is extended and retracted, thereby driving the web to flip. This control method realizes the automatic control of the flipping process without manual intervention, thereby improving production efficiency.

[0028] In order to achieve accurate control of the web flip angle, the control system 6 also includes an angle sensor (not shown in the figure) for detecting the flip angle of the web. The control system 6 controls the start and stop of the drive motor 7 according to the flip angle detected by the angle sensor, thereby ensuring that the web can be accurately flipped to a preset angle, such as 180°. This precise flip angle control ensures that the web is flipped to a predetermined position, improves product quality, and avoids deviations in subsequent hoisting and installation.

[0029] In order to provide effective support to the web and prevent deformation during the flipping process, a support structure for supporting the web is also provided on the tooling body 2. In this embodiment, the support structure includes a support plate (not shown in the figure) and a plurality of support columns (not shown in the figure). The support column is arranged on the support plate, and a support surface matching the web is arranged at the top of the support column, which is used to provide support during the flipping process of the web, prevent the web from being deformed due to its own weight, and ensure the shape accuracy of the web. In order to adapt to webs of different sizes, the height of the support column is adjustable to better meet actual production needs.

[0030] The working process of the fan blade web demoulding and flipping tool provided by the utility model is as follows:

[0031] First, the whole tooling 2 is connected to the crane through the hook 1 above the tooling, and the tooling 2 is lifted and placed above the web to be demoulded. Next, the control system 6 is turned on to control multiple vacuum suction cups 3 to be adsorbed on the surface of the web. Then, the crane is raised to drive the tooling body 2 and the web adsorbed thereon to rise together, thereby achieving separation of the web from the mold.

[0032] After demoulding is completed, the web is hoisted to the designated area, the web flip control 6 is turned on, the drive motor 7 is started, and the electric telescopic rod 5 and the crankshaft 4 are driven by electricity to rotate. The drive motor 7 drives the crankshaft 4 to rotate, and the rotational motion of the crankshaft 4 is transmitted to the electric telescopic rod 5 through the connecting rod 10, so that it performs telescopic motion, thereby driving the web flip.

[0033] After the web plate rotates 180°, the angle sensor feeds back the detected flip angle to the control system 6, and the control system 6 automatically turns off the drive motor 7, stops the rotation of the crankshaft 4, and realizes the 180° flip of the web plate. At this time, the support structure provides stable support during the flipping process of the web plate, avoids deformation of the web plate due to its own weight, and ensures the shape accuracy of the web plate.

[0034] In summary, the fan blade web demoulding and flipping tooling provided by the utility model can realize automatic flipping of the web by setting a flipping mechanism and a control system without additional operation of the positioning component, thus solving the problem of complicated flipping operation and low efficiency in the prior art. At the same time, the precise control of the flipping angle by the control system also ensures the accuracy of the web flipping, thus solving the problem of the positioning accuracy being difficult to ensure and affecting the product quality in the prior art. In addition, the utility model also sets a support structure to provide effective support to the web during the flipping process to prevent deformation, thus further improving the product quality.
