[0068] Before using the device, check that the device circuit connection is correct, wipe the work surface and upper beam components clean, ensure that there is no dirt on the work surface, and prevent the inclusion of dirt during the rolling process from affecting the final quality of the composite material product.
[0069] Before the formal automatic rolling and pasting, the device is first run in an empty run, mainly to ensure the positive and negative linear movement of the Z axis of the moving beam assembly of the device, the positive and negative movement of the X and Y axes of the working panel and the reliable operation of the travel limit device.
[0070] Rotate the knob of the operating control box to the up position, lift the pneumatic arm to the highest position along the positive direction of the z-axis, place the selected rolling mandrel in the middle of the chuck, align the mounting holes of the chuck and the mandrel, and another person slowly turns the handwheel in a clockwise direction to slowly clamp the chuck through forward and reverse screws, linear guide rails, sliders, etc., until the rolling mandrel is finally clamped between the two chucks, and ball bearings are installed on the outside of the rolling mandrel as fixed and sliding shafts at both ends of the shaft. The mandrel can achieve free rotation along the axial direction through deep groove ball bearings.
[0071] Adjust the position of the working panel, and realize its movement to the maximum displacement in the negative direction of the X direction by adjusting the lower movable panel, and make the working panel repositioned in the middle position of the rolling axis by adjusting the upper movable panel. The working principle of the upper and lower movable panels is to achieve the output of the appropriate rolling speed through the stepper motor and the planetary reducer assembly, transmit power through the synchronous belt, and realize the guidance and reliability of linear motion through the linear guide rail and the slider installed on the upper and lower movable panels.
[0072] After the working panel and rolling shaft are adjusted to the appropriate position, the prepreg or sheet prepared in advance is laid flat on the working plane to ensure that it is laid flat and wrinkles and bubbles are prohibited.
[0073] The material properties and paving process of the composite material raw materials can be used to determine whether the material needs to be preheated during the paving process. If necessary, turn on the heating control switch to heat the working panel to the specified temperature.
[0074] After the sheet is laid and preheated to the predetermined temperature, the knob of the operating control box is adjusted to the downward gear, so that the air pressure arm moves along the negative direction of the z-axis until it is in close contact with the sheet. The pressure gauge on the control cabinet can be used to monitor the pressure of the air pressure arm in real time and adjust it to adjust the pressure of the rolling core shaft on the sheet.
[0075] After the rolling core shaft presses the sheet, one person pulls and tensions the sheet to provide a certain rolling tension to the sheet. The sheet is parallel to the working plane. The remote control handle makes the panel move at a constant speed along the positive direction of the x-axis, tightly wraps the sheet around the shaft, and grabs the remaining sheet to increase the winding tension. The force is enough for the shaft to just rotate with the movement of the panel.
[0076] When the panel moves to the maximum value along the positive direction of the x-axis, stop the control handle, rotate the knob to the up position, and lift the air pressure arm to the highest position.
[0077] When the rolling mandrel rises to the highest position and stops, use the mobile control handle to move the work plane along the negative direction of the x-axis to the maximum value, and repeat steps 8 and 9 until the paving is completed.
[0078] After the paving is completed, the working panel and the rolling mandrel are restored to the initial position. One person holds the rolled mandrel and the product with his hands, and the other person slowly turns the handwheel in a counterclockwise direction to slowly loosen the chuck through the forward and reverse screws, linear guide rails, sliders, etc., and finally the rolling mandrel is separated from the two chucks.
[0079] The rolled mandrel and the sheet rolled on it are removed, vacuum bagging is performed, and the product is heated and pressurized in an autoclave for curing, and finally the product is cured and formed.
