Embodiment 1

[0029] The wind power blade preform production method of the present embodiment includes the following steps automatically controlled by the industrial computer:

[0030] ①. Send two different fabrics to two sets of cutting mechanisms through two sets of constant micro-tension unwinding mechanisms.

[0031] ②. Two sets of cutting mechanisms cut the two kinds of fabrics respectively: the cutting mechanism is equipped with an industrial laser projector, and the industrial laser projector projects the pattern that needs to be cut out of the fabric onto the fabric in a ratio of 1:1. The cutting machine cuts the fabric according to the projected graphics.

[0032] ③. Grasp the fabrics cut by two sets of cutting mechanisms through the mechanical arm, and stack them on the turnover frame transported by the first conveying line; specifically: install the cloth frame on the robotic arm, and install it on the frame Multiple needle-punched suction cups, controlled by the valve island, c...

Abstract

The invention discloses a production method of a wind turbine blade preform. The method comprises steps as follows: 1, unwinding is performed; 2, cutting is performed; 3, cloth is grabbed by a mechanical arm and stacked on a transfer frame conveyed by a first conveying line; 4, the cloth is sewn; 5, the cloth on the transfer frame is jacked up by a jacking and cloth taking mechanism and sent to a metal detection mechanism, and after passing through the metal detection mechanism, the cloth enters a stacking and discharging mechanism for discharging; 6, the unloaded transfer frame is jacked up by a jacking and translation mechanism and sent to an input end of a second conveying line; 7, the unloaded transfer frame is conveyed backwards by the second conveying line to an output end of the second conveying line; 8, the unloaded transfer frame is jacked up by the jacking and translation mechanism and sent to an input end of the first conveying line; 9, the unloaded transfer frame is received by the jacking and translation mechanism arranged at the bottom of the input end of the first conveying line, and the steps are circularly executed by starting from the step 3. Automatic production of the wind turbine blade preform is realized, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to a preformed production method of wind power blades. Background technique [0002] As the timetable for the depletion of traditional fossil energy such as coal, oil, and natural gas is approaching, the development and utilization of wind energy has attracted more and more attention, and it has become one of the most promising projects in the energy field. develop rapidly. With the emergence of network-connected wind turbines, wind power has entered a period of rapid development. When blades of traditional materials are used on increasingly large-scale wind turbines, some performances can no longer meet the requirements. Therefore, composite blades with high specific strength have been developed. stand up. [0003] At the root of wind power blades, there is a piece that needs to be stacked in multiple layers and then stitched to form a preform. The preform is made of about 20 layers of glass fiber cloth of various shapes stacke...
