Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind power blades, in particular to an automatic assembly equipment for wind power blades. BACKGROUND

[0002] The web plate is a key component of the wind power blade and plays a role in resisting shear in the structure of the whole blade. The common web plate is a double-symmetric structure. The single web plate after forming is connected into an integrated body by assembly and then installed in the inner cavity of the blade. The width, height and curve of the web plate are different for different blade types. The assembly of the single web plate needs to be directly assisted and fixed by a special web plate assembly tool to complete the assembly. The size of the support and the assembly precision are crucial. The current web plate assembly tool is customized according to the blade type and does not have universality. Multiple sets of web plate assembly supports with fixed sizes need to be customized for each blade type. After the blade type is discontinued, the corresponding web plate assembly support is discarded and cannot be reused. The tool investment cost is large. After the single web plate is fixed on the web plate assembly tool, a large clamp is installed every 0.5-2 meters to tighten and fix the web plate, which is time-consuming and labor-intensive. The whole process is manually operated. The size of the web plate assembly tool changes after a long time of use. The current web plate assembly tool cannot be adjusted due to the fixed size of the surface and support mechanism. Long-term non-correction will affect the assembly precision of the web plate and the product quality. If correction is performed, a new template needs to be made, which has a large correction cost, a long period and will delay the production progress.

[0003] In order to solve the above problems, the patent for invention with publication number CN 110340846 B discloses a kind of automatic assembly tool for wind power blade web plate. In the scheme, the tool support, the side support mechanism arranged on the back of web plate and the bottom support mechanism arranged on the bottom of web plate are set;The side support mechanism on one side of tool support is positioning support mechanism, and the side support mechanism on the other side of tool support is pneumatic pressing mechanism;Positioning support mechanism includes positioning support screw and fixed nut, and fixed nut is installed on tool support;Pneumatic pressing mechanism includes pneumatic mounting frame and pressing cylinder, and pressing cylinder is connected with control cabinet through cylinder control line. By setting pneumatic pressing mechanism, positioning support mechanism and bottom support mechanism, the assembly of web plate is realized. By setting angle adjusting mechanism and locking mechanism, the left, right, up and down adjustment of web plate can be realized. It can be suitable for web plates with different widths, heights and curves. The tool has strong universality, greatly saves tool investment cost, improves the clamping precision of web plate assembly and ensures the assembly quality.

[0004] However, the above scheme still has some deficiencies. In the above scheme, multiple cylinder structures are used to support the web plate, which needs to consume a lot of time for adjustment during use, affecting the production and processing efficiency. SUMMARY
