Background

The composite blade consists of 2 halves. One half of which is called the PS plane and the other is called the SS plane. Each half has a leading edge and a trailing edge. During manufacture, the two halves are produced separately in a mold, and subsequently they will be glued together. To bond the PS side and the SS side together, an edge-on bond along the leading and trailing edges is required. The seam area where the two halves are bonded together is called a co-molded seam.

In the production of the PS side and the SS side, a lot of excess material is created in the pinch seam area for ease of production, which must be removed in order to ensure a good joint between the suction and pressure sides. 1-3m of the rotor blade is the most important area, and the area is the last part of the rotor blade, and the bonding surface needs to be accurately positioned to ensure the accuracy of the die-closing seam.

In the past, composite blades were machined by a hand grinder. The glass fiber dust of the composite material is used as a main pollution source in the wind power blade processing industry and is an important factor for restricting the occupational health development of enterprises. In addition, the thickness of the material needing to be cut off of the die-closing seam in the 1-3m area of the blade is basically more than 100mm, and the excessive material is cut off by manually holding the angle grinder, so that the higher mechanical injury risk is accompanied.
