A post-molding station is described which is used in the manufacturing of a wind turbine blade. A blade shell forming part of a wind turbine blade is initially molded in a blade mold, the blade shell subsequently transferred to a post-molding station which allows for various post-molding operations to be carried out on the blade shell away from the mold, thereby increasing the productivity of the blade mold in the manufacturing process. The post-molding station may be operable to perform the closing of first and second blade shells to form a wind turbine blade, and may be formed from an adjustable structure which can provide relatively easy access to the contained blade shell for working thereon. Accordingly, the manufacturing equipment may be of reduced cost, combined with an increase in the overall productivity of the manufacturing system.

1. A post-moulding station for performing at least one post-moulding operation on at least a section of a cured wind turbine blade shell of at least 40 meters length, the post-moulding station comprising: a first cradle to receive at least a section of a first cured blade shell transferred from a blade mould;a second cradle to receive at least a section of a second cured blade shell transferred from a blade mould, said first and second cured blade shells together substantially forming a wind turbine blade;wherein at least one post-moulding operation can be performed on at least one surface of said first and second cured blade shells received in said cradles,wherein at least one of said first and second cradles is a substantially open-framed structure to provide access to a supported surface of a cured blade shell received in said cradle, the cradle having a plurality of support members to support a surface of a cured wind turbine blade shell received in said cradle,wherein the first cradle is adapted to receive an upwind or pressure side blade shell and the second cradle is adapted to receive a downwind or suction side blade shell,wherein the post-moulding station is adapted to align the upwind blade shell and the downwind blade shell along a leading edge and a trailing edge,wherein the post-moulding station further comprises a closing mechanism operable to translationally move said first cradle relative to said second cradle to form a closed cradle, such that said first cured blade shell is connected to said second cured blade shell within said closed cradle to form a wind turbine blade, andwherein a hinge couples the first cradle to the second cradle and assists the first cradle translationally moving relative to the second cradle. 2. A manufacturing system for the manufacture of wind turbine blades formed from a pair of cured blade shells bonded together, the system comprising: a first upwind blade mould to produce at least a portion of a first upwind cured blade shell;a second downwind blade mould to produce at least a portion of a second downwind cured blade shell;a post-moulding station as claimed in claim 1 to receive said first and second cured blade shells from said first upwind blade mould and second downwind blade mould, wherein a post-moulding operation can be performed on said first and second cured blade shells at said post-moulding station; anda closing mechanism operable to rotationally move the first upwind blade mould relative to the second downwind blade mould to close said first and second cured blade shells to form a wind turbine blade. 3. A method of performing at least one post-moulding operation on at least a section of a cured wind turbine blade shell, the method comprising the steps of: providing at least a section of a first cured blade shell in a blade mould;transferring said at least a section of a first cured blade shell from a blade mould to a first cradle of a post-moulding station as claimed in claim 1;providing at least a section of a second cured blade shell in a blade mould;transferring said at least a section of a second cured blade shell from a blade mould to a second cradle of said post-moulding station;performing at least one post-moulding operation on at least one surface of said first and second cured blade shells received in said cradles; androtating the first cradle relative to the second cradle to form a closed cradle,wherein at least one of said cradles is provided as a substantially open-framed structure to provide access to a supported surface of a cured blade shell received in said cradle, and wherein said at least one post-moulding operation is performed on at least a portion of said supported surface through said open-framed structure. 4. A post-moulding station for performing at least one post-moulding operation on at least a section of a cured wind turbine blade shell of at least 40 meters length, the post-moulding station comprising: a first cradle to receive at least a section of a first cured blade shell transferred from a blade mould;a second cradle to receive at least a section of a second cured blade shell transferred from a blade mould, said first and second cured blade shells together substantially forming a wind turbine blade;wherein at least one post-moulding operation can be performed on at least one surface of said first and second cured blade shells received in said cradles,wherein at least one of said first and second cradles is a substantially open-framed structure to provide access to a supported surface of a cured blade shell received in said cradle, the cradle having a plurality of support members to support a surface of a cured wind turbine blade shell received in said cradle,wherein the plurality of support members comprise individually moveable vacuum clamps which are selectively applied,wherein the first cradle is adapted to receive an upwind or pressure side blade shell and the second cradle is adapted to receive a downwind or suction side blade shell,wherein the post-moulding station is adapted to align the upwind blade shell and the downwind blade shell along a leading edge and a trailing edge, andwherein the post-moulding station further comprises a closing mechanism operable to move said first cradle relative to said second cradle to form a closed cradle, such that said first cured blade shell is connected to said second cured blade shell within said closed cradle to form a wind turbine blade. 5. A manufacturing system for the manufacture of wind turbine blades formed from a pair of cured blade shells bonded together, the system comprising: a first upwind blade mould to produce at least a portion of a first upwind cured blade shell;a second downwind blade mould to produce at least a portion of a second downwind cured blade shell;a post-moulding station as claimed in claim 4 to receive said first and second cured blade shells from said first upwind blade mould and second downwind blade mould, wherein a post-moulding operation can be performed on said first and second cured blade shells at said post-moulding station, wherein the post-moulding station comprises at least one cradle comprising a plurality of support members, wherein the plurality of support members comprises individually moveable vacuum clamps which are selectively applied; anda closing mechanism operable to close said first and second cured blade shells to form a wind turbine blade. 6. A method of performing at least one post-moulding operation on at least a section of a cured wind turbine blade shell, the method comprising the steps of: providing at least a section of a first cured blade shell in a blade mould;transferring said at least a section of a first cured blade shell from a blade mould to a first cradle of a post-moulding station as claimed in claim 4;providing at least a section of a second cured blade shell in a blade mould;transferring said at least a section of a second cured blade shell from a blade mould to a second cradle of said post-moulding station; andperforming at least one post-moulding operation on at least one surface of said first and second cured blade shells received in said cradles,wherein at least one of said cradles is provided as a substantially open-framed structure to provide access to a supported surface of a cured blade shell received in said cradle, wherein the at least one of said cradles comprises a plurality of support members comprising individually moveable vacuum clamps which are selectively applied, and wherein said at least one post-moulding operation is performed on at least a portion of said supported surface through said open-framed structure.
