Description

Technical Field

[0001] This invention relates to the field of wind turbine blade manufacturing technology, and in particular to a pultruded sheet assembly tooling. Background Technology

[0002] Currently, wind turbine blades are increasingly trending towards larger and lighter designs. Therefore, pultruded glass sheets and pultruded carbon sheets are widely used in the fabrication of the main beams of wind turbine blades. After assembling multi-layer pultruded sheets, tensioning fixtures are typically used to lock and fix them in place, resulting in a multi-layered structure where each layer comprises multiple non-overlapping but mutually abutting pultruded sheets. However, due to the long dimensions and significant curvature of the pultruded sheets, they are prone to shifting between layers during assembly, transportation, and hoisting, leading to defects such as misalignment, gaps, and stacking of multiple pultruded sheets within the same layer.

[0003] Defects such as misalignment and gaps among multiple pultruded sheets in the same layer can be easily identified through visual inspection and can be reworked promptly. However, stacking defects between multiple pultruded sheets in the same layer are difficult to identify without vacuum tightening. Furthermore, visual inspection cannot effectively identify stacking defects between multiple pultruded sheets in the same layer. Such defects cannot be repaired in a timely manner, easily leading to problems such as low finished product quality or even product scrap.

[0004] Therefore, there is an urgent need for a pultruded sheet assembly tool to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a pultruded sheet assembly tooling that can achieve interlayer control, position the pultruded sheet, and avoid defects such as misalignment, gaps, and stacking between pultruded sheets in the same layer.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A pultruded sheet assembly fixture, on which multiple pultruded sheets can be stacked to form a pultruded main beam, the pultruded sheet assembly fixture comprising:

[0008] Base;

[0009] A conformal support mechanism is provided on the base, the shape of the bearing surface of the conformal support mechanism matching the shape of the pultruded sheet, to support the pultruded main beam;

[0010] An interlayer positioning mechanism includes a plurality of first positioning pieces spaced apart along a first direction. The plurality of first positioning pieces are vertically height-adjustable on the base and can be inserted into the pultruded main beam to position a plurality of pultruded sheets.

[0011] The first direction is perpendicular to the vertical direction.

[0012] As a preferred embodiment of the pultruded sheet assembly tooling provided by the present invention, the interlayer positioning mechanism further includes a fixing component and an adjusting component. The first positioning piece is spaced apart on the fixing component, the fixing component is disposed on the adjusting component, and the adjusting component is height-adjustably disposed on the base.

[0013] As a preferred embodiment of the pultruded sheet assembly tooling provided by the present invention, the adjusting component includes a lifting seat and a screw. The lifting seat is fixed relative to the base, and the screw is rotatably screwed into the lifting seat. When the screw rotates, the relative distance between the top end of the screw and the base can be adjusted. The fixing component is connected to the top end of the screw.

[0014] As a preferred embodiment of the pultruded sheet assembly tooling provided by the present invention, there are two adjustment components, which are spaced apart on the base along a first direction.

[0015] As a preferred embodiment of the pultruded sheet assembly fixture provided by the present invention, the conformal support mechanism includes a bracket and an arc plate. The bracket is disposed on the base, the arc plate is disposed on the top of the bracket, and the end face of the arc plate facing away from the bracket is the bearing surface.

[0018] As a preferred embodiment of the pultruded sheet assembly tooling provided by the present invention, the interlayer positioning mechanism further includes a plurality of second positioning pieces. Between two adjacent conformal support mechanisms, a plurality of second positioning pieces are spaced apart along a first direction. The plurality of second positioning pieces can be inserted into the pultruded main beam in a vertical direction to position a plurality of pultruded sheets.

[0020] As a preferred embodiment of the pultruded sheet assembly tooling provided by the present invention, the base is a transfer vehicle.

[0021] The beneficial effects of this invention are:

[0022] The pultruded sheet assembly fixture provided by this invention includes a base, a conformal support mechanism, and an interlayer positioning mechanism. The conformal support mechanism is disposed on the base, and the shape of its bearing surface matches the shape of the pultruded sheet, supporting the pultruded sheet.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] Figure 1 This shows a front view of the pultruded sheet assembly tooling provided in an embodiment of the present invention; Figure 2 This diagram shows a partial structural side view of the pultruded sheet assembly tooling provided in an embodiment of the present invention, wherein the first direction is perpendicular to the vertical direction. (Refer to...) Figure 1 and Figure 2 This embodiment provides a pultruded sheet assembly fixture. Multiple pultruded sheets 11 can be stacked on the pultruded sheet assembly fixture to form a pultruded main beam 10. The pultruded main beam 10 has a multi-layer structure, and each layer includes multiple pultruded sheets 11. The multiple pultruded sheets 11 in the same layer are not stacked but are arranged to abut against each other.

[0037] Specifically, the pultruded sheet assembly fixture includes a base 100, a conformal support mechanism 200, and an interlayer positioning mechanism 300. The conformal support mechanism 200 is disposed on the base 100 and is used to support the pultruded main beam 10. The interlayer positioning mechanism 300 is disposed on the base 100 and can limit the pultruded sheet 11 in the pultruded main beam 10 to prevent defects such as misalignment, gaps, and stacking between pultruded sheets 11 in the same layer.

[0038] Alternatively, in this embodiment, the base 100 is a transfer vehicle. The conformal support mechanism 200 and the interlayer positioning mechanism 300 are integrated with the transfer vehicle, and can position the pultruded sheet 11 during the transfer of the pultruded main beam 10.

[0039] More specifically, there are multiple conformal support mechanisms 200, which are arranged parallel to each other and spaced apart on the base 100. The multiple conformal support mechanisms 200 can simultaneously support the pultruded main beam 10 to ensure the support stability and reliability of the pultruded main beam 10.

[0040] More specifically, the pultruded sheet assembly fixture also includes a positioning stop mechanism 400. This positioning stop mechanism 400 is disposed on the base 100 and extends vertically, with one end of the pultruded main beam 10 abutting against it. Through this arrangement, the positioning stop mechanism 400 can abut against the lower end of the pultruded main beam 10 in the vertical direction, thereby achieving end positioning of the pultruded main beam 10.

[0041] Preferably, there are two positioning and stopping mechanisms 400, which are spaced apart on the base 100 along the first direction. That is, one of the two positioning and stopping mechanisms 400 can be selected to achieve the abutment of the end of the pultruded main beam 10 with the lower height in the vertical direction, without specifying the specific setting direction of the conformal support mechanism 200 in the first direction.

[0042] Continue to refer to Figure 1 The conformal support mechanism 200 includes a bracket 210 and an arc-shaped plate 220. The bracket 210 is disposed on the base 100, as shown in the figure. Figure 2 The interlayer positioning mechanism 300 is offset from the arc plate 220. The arc plate 220 is located on the top of the bracket 210, and the end face of the arc plate 220 facing away from the bracket 210 is the bearing surface. The shape of the bearing surface matches the shape of the pultruded sheet 11, which can stably and reliably support the pultruded main beam 10.

[0043] Continue to refer to Figure 1 and Figure 2The interlayer positioning mechanism 300 includes multiple first positioning pieces 310 spaced apart along a first direction. These first positioning pieces 310 are vertically height-adjustable on the base 100 and can be inserted into the pultruded main beam 10 to position multiple pultruded sheets 11. Specifically, the first positioning pieces 310 divide the multiple pultruded sheets 11 in the pultruded main beam 10 into multiple modules. These modules abut against each other but do not overlap, and each module includes multiple pultruded sheets 11 stacked together. The multiple first positioning pieces 310 enable interlayer control of the pultruded main beam 10, preventing stacking of multiple pultruded sheets 11 within the same layer.

[0044] Specifically, the interlayer positioning mechanism 300 further includes a fixing component 320 and an adjusting component 330. The first positioning piece 310 is spaced apart on the fixing component 320, the fixing component 320 is disposed on the adjusting component 330, and the adjusting component 330 is height-adjustably disposed on the base 100.

[0045] More specifically, the adjusting assembly 330 includes a lifting seat 331 and a screw 332. The lifting seat 331 is fixed relative to the base 100, and the screw 332 is rotatably screwed into the lifting seat 331. Rotation of the screw 332 adjusts the relative distance between its tip and the base 100. The tip of the screw 332 is rotatably connected to the fixing assembly 320 via a bearing. When the screw 332 rotates, it can rise and fall relative to the lifting seat 331 and rotate relative to the fixing assembly 320. The fixing assembly 320 is height-adjusted under the influence of the screw 332.

[0046] Optionally, there are two adjustment components 330, which are spaced apart on the base 100 along the first direction. The screws 332 of the two adjustment components 330 are rotatably connected to a fixing component 320 to ensure the stability of the fixing component 320 when adjusting its height.

[0047] Figure 3 This diagram illustrates the distribution of the pultruded sheet, the first positioning piece, and the second positioning piece according to an embodiment of the present invention. (Refer to...) Figure 3 The interlayer positioning mechanism 300 provided in this embodiment also includes a plurality of second positioning pieces 340. A plurality of second positioning pieces 340 are spaced apart between two adjacent conformal support mechanisms 200 along a first direction. These second positioning pieces 340 can be inserted vertically into the pultruded main beam 10 to position a plurality of pultruded sheets 11. The aforementioned second positioning pieces 340 and the base 100 are designed separately, which, based on the plurality of first positioning pieces 310, further increases the density of positioning points of the pultruded sheets 11 in the pultruded main beam 10, and further improves the positioning reliability of the pultruded sheets 11.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
