[0042] This embodiment also provides a tape laying method, which is implemented by the tape laying head device suitable for the composite material fully automatic tape laying equipment provided in the above embodiment, and the steps are as follows: Preparation work before feeding and replenishing: measure the measuring tooling assembly through the tracker, reasonably adjust the placement of the tape roll, and manually adjust the center of the tape guide assembly through the centering knob; manually adjust the cutting depth of the prepreg tape cutting assembly, and manually move the cutter to the knife length measurement module.

[0043] Strip unwinding: Start the strip unwinding assembly drive motor, the unwinding assembly drive motor rotates to drive the unwinding roller to rotate, and unwind the strip. The prepreg tape clamping and unwinding assembly is mainly used for clamping and unwinding prepreg tapes. The central axis that drives the prepreg tape to rotate should be servo-controlled and can perform interpolation motion with other axes. The diameter of the reel is measured by a laser rangefinder sensor, and the torque of the reel mechanism is dynamically controlled according to the reel diameter to achieve precise tension; Automatic web deflection correction: Start the automatic deflection correction component, the edge detection sensor immediately detects the edge of the web, and feeds back the deviation signal to the deflection correction component drive motor.

The strip guide assembly has a mechanical limit for the edge of the prepreg strip, which can ensure the correct direction of the prepreg strip delivery and can be adjusted manually.

[0047] The heating component is heated before the prepreg tape is laid. The heat source temperature of the heating component is required to be displayed. Within the temperature controllable range, the accuracy of display and control temperature is ≤± 3℃, and the upper limit of heating is 100℃.

[0048] The belt pressing shoe assembly compacts the belt material: the belt pressing shoe cylinder drives the pressing shoe assembly to move downward, and the air pressure drives the pressing shoe piece to press downward, so that it fully contacts with the belt material and compacts the belt material.

[0049] The belt material pressing roller assembly lays the belt material: the pressing roller assembly extends out, and the electric cylinder drives the roller of the pressing roller assembly to swing downward, driving the roller to press the belt material, so that the belt material is laid reasonably.

The ultrasonic cutter is integrated into the tape laying head and is located on one side of the tape laying head. The cutter is driven by ultrasound and can cut multiple layers of uncured prepreg that have been laid on the tooling. The cutting depth of each cut is ≥4mm, the total cutting depth is ≥20mm, and the cutting depth accuracy is ≤1mm.

[0051] The tape pressure shoe assembly retracts and the pressure roller assembly is lifted up: the pressure roller assembly retracts, the cylinder is ventilated to make the pressure roller swing upward, the pressure shoe cylinder is de-aired to make the pressure shoe retract, driving the pressure shoe and pressure roller away from the surface of the tape, and the tape laying is completed.

[0052] In summary, the device provided in this embodiment has a simpler structure and is more aesthetically pleasing on the basis of meeting the requirements of automatic tape laying. The device structure is reasonably designed, occupies a small area, and the main body of the device structure and the transmission mechanism have undergone finite element analysis and professional calculations to meet sufficient technical requirements such as static, dynamic, and thermal stiffness. This effectively solves the problems of unstable laying quality and low efficiency caused by manual laying of large-size and small-curvature parts.
