Description

Technical Field

[0001] The present invention belongs to the technical field of fiber placement equipment, and in particular relates to a low-resistance material storage and conveying device for fiber placement and an automatic fiber placement system. Background Art

[0002] In existing automatic fiber placement systems, fiber bundles must be transported with low resistance to avoid defects such as bridging caused by excessive tension after placement. In addition, the fiber bundle prepreg used in automatic fiber placement is a thermosetting material with a viscosity that increases with increasing temperature and decreases with decreasing temperature. For example, the existing patent CN118124173A discloses a low-resistance fiber conveying device for laying silk, including a base and a flexible conveying installation assembly, the flexible conveying installation assembly including a flexible air duct, a plurality of balancers are arranged above the flexible air duct, and the balancers are connected to the flexible air duct through a pull rope; a plurality of flexible conveying tubes are installed between the two ends of the flexible air duct, and the flexible conveying tubes include a first flexible tube, a second flexible tube, a first flexible slat, a second flexible slat, and a third flexible slat; the outer side of the second flexible tube is sleeved with a first flexible tube, a first flexible slat is arranged on one side between the first flexible tube and the second flexible tube, and a second flexible slat and a third flexible slat are arranged on the other side, and the total length of the second flexible slat is less than that of the first flexible slat and are interconnected; cold air is circulated inside the flexible air duct. This solution uses a balancer to prevent the flexible conveying tube from experiencing significant deformation as it moves with the placement head, thereby controlling fiber transport resistance. Furthermore, the first flexible tube is configured as a bellows, and the first, second, and third flexible strips work together to clamp the second flexible tube, preventing twisting and deformation as it moves with the placement head, while also improving overall plastic deformation capacity. However, this solution does not optimize the storage equipment.

At the same time, due to size limitations, the equipped tension reduction module is relatively simple, resulting in greater fiber tension during placement, which is prone to quality defects such as fiber bridging.

DETAILED DESCRIPTION

[0020] Example 1: A low resistance material storage and conveying device for wire laying, such as Figure 1 As shown, it includes a storage box 1, a balancing system 2 and a fiber conveying channel 3; the balancing system 2 is provided on one side of the storage box 1, and the fiber conveying channel 3 is provided below the balancing system 2.

[0021] Preferably, multiple groups of yarn spreading modules 11 and tension reducing modules 12 are installed in the storage box 1, such as Figure 2 As shown, the yarn spreading module 11 includes a yarn unwinding roller 111, a backing recovery roller 112, and a guide roller 113. The fiber material roller 6 is mounted on the yarn unwinding roller 111. When the fiber tow 62 is tightened, the fiber material roller 6 passively unwinds, while the backing recovery roller 112 synchronously recovers the fiber backing 61. Preferably, the storage box 1 is provided with 8 sets of yarn spreading modules 11 and 8 sets of tension reduction modules 12.

[0022] like Figure 3 and Figure 4As shown, the tension reduction module 12 includes a tension reduction drive roller 121, a tension reduction belt 122 and a plurality of tension reduction guide mechanisms. Preferably, the tension reduction guide mechanisms are greater than or equal to 5 groups. Specifically, the tension reduction guide mechanism includes a spinning apron 123, a separator 124 and a tension reduction guide roller 125. The tension reduction guide roller 125 is connected to the tension reduction drive roller 121 through the tension reduction belt 122, and the tension reduction drive roller 121 provides power for continuous rotation. The separator 124 is arranged between the spinning apron 123 and the tension reduction guide roller 125. The inner circumference of the spinning apron 123 is slightly larger than the outer contour circumference formed by the tension reduction guide roller 125 and the separator 124. The spinning apron 123 can be rotated between the tension reduction guide roller 125 and the separator 124. The outer contour surface formed by 24 rotates, and when the rear end of the fiber bundle 62 is subjected to tension, the fiber bundle 62 makes the spinning leather ring 123 close to the tension-reducing guide roller 125, and the tension-reducing guide roller 125 gives the spinning leather ring 123 a driving force forward. The spinning leather ring 123 gives the fiber bundle 62 a driving force forward. The greater the pulling force, the greater the driving force, thereby offsetting the pulling force and reducing the tension of the fiber bundle 62. Under the joint action of the five groups of spinning leather rings 123, the partition blocks 124 and the tension-reducing guide rollers 125, the tension of the fiber bundle 62 can be reduced to close to 0.

The fiber conveying channel 3 includes a wire guide tube 31 and a thermal insulation shield tube 32. Each fiber tow 62 passes through a different wire guide tube 31 to the fiber placement head 5. At the same time, cold air is passed through the thermal insulation shield tube 32 to keep the interior at a low temperature, reduce the viscosity of the fiber tow 62, and thus reduce the fiber conveying resistance. Preferably, the wire guide tube 31 in the fiber conveying channel 3 is made of high-density polytetrafluoroethylene that is not easy to adhere to the fiber tow 62 and is antistatic; at the same time, cold air is passed through the thermal insulation shield tube 32 to keep the interior of the fiber conveying channel 3 at a low temperature, reduce the viscosity of the fiber tow 62, and thus achieve low-resistance fiber conveying.

[0024] Preferably, if Figure 1 As shown, the balancing system 2 is equipped with multiple sets of balancers 21. As the fiber delivery channel 3 moves with the placement head 5, the balancers 21 provide a constant torque to the pull ropes, ensuring that the fiber delivery channel 3 is generally smooth and free of significant bending and deformation, thereby preventing significant resistance during the delivery of the fiber tows 62. Specifically, the pull ropes of the balancers 21 are hung on the fiber delivery channel 3. By adjusting the hanging point and torque of the balancers 21, the guide tubes 31 in the fiber delivery channel 3 do not experience significant deformation when moving with the placement head 5, thereby controlling the fiber delivery resistance.

Specifically, a vortex tube 512 is installed on the fixed base for blowing cooling air into the placement head 5 to reduce the resistance of the fiber tow 62 during transportation within the placement head 5. The placement head 5 is mounted on the flange of the robot 4 through the placement head mounting flange 511 and is equipped with a vortex tube 512 for blowing cooling air into the placement head 5 to maintain a low temperature inside the placement head 5 and reduce the resistance of the fiber bundle 62 to be transported in the placement head 5.

Under the action of the compacting cylinder 544, the laying pressure roller 541 can make linear motion when the compacting cylinder 544 is actuated, thereby compensating for the dimensional error of the surface to be laid and compacting the ply.

[0028] Preferably, the fiber placement head moving part 52 is equipped with a heating device 53, which includes an infrared probe 531 and a radiation heat source 532.

At the same time, the infrared probe 531 is used to realize closed-loop control of the heating temperature to ensure that the fiber bundle 62 is heated and has sufficient viscosity to be compacted and laid on the surface to be laid.

[0029] Preferably, if Figure 7As shown, the placing head moving part 52 is equipped with an upper wire guide plate 551 and a lower wire guide plate 552 for guiding the odd-numbered fiber bundles 621 and the even-numbered fiber bundles 622 and finally bundling them into a wide band with variable width.

The odd fiber driving roller 561 and the even fiber driving roller 562 are respectively equipped with drives, and their rotation linear speed is consistent with the placement speed. The odd fiber tows 621 and the even fiber tows 622 need to be When re-feeding is required, the corresponding odd fiber feeding cylinder 565 and even fiber feeding cylinder 566 are activated, so that the odd fiber enabling roller 563 and the even fiber enabling roller 564 correspondingly press the odd fiber bundles 621 and the even fiber bundles 622 onto the odd fiber driving roller 561 and the even fiber driving roller 562, so that the odd fiber driving roller 561 and the even fiber driving roller 562 correspondingly carry the odd fiber bundles 621 and the even fiber bundles 622 toward the laying pressure roller 541.

[0031] Preferably, the fiber bundle 62 has a shearing function, and the laying head moving part 52 is equipped with an odd fiber shearing anvil 571, an even fiber shearing anvil 572, an odd fiber cutter 573, an even fiber cutter 574, an odd fiber shearing cylinder 575 and an even fiber shearing cylinder 576.
