Description

Technical Field

[0001] The invention belongs to the field of composite material processing equipment, and in particular relates to a tape pressing roller device and a control method suitable for composite material full-automatic tape laying equipment. Background Art

[0002] The manufacturing of composite parts is a process of laying prepreg tapes layer by layer, compacting them and then curing them. The laying and compacting of prepreg tapes are the most critical operations in the manufacturing of composite parts. By laying and compacting the prepreg tapes, the gas in the laying process of the prepreg tapes can be effectively discharged, making the layers more tightly bonded, fully ensuring the quality of composite parts.

[0003] During the prepreg tape compaction process, the compaction force generated must be reasonably suitable for the material properties to avoid surface damage.

[0004] The existing tape laying machine's tape material compacting device does not have an obvious compacting effect on curved surface conditions, thereby affecting the tape material laying efficiency and laying accuracy.

[0005] At present, the compaction operation after the completion of the paving by a large number of tape laying machines is done manually, which is labor-intensive and difficult to meet the needs of mass production schedules. In addition, when the operator presses, the compaction operation will be unevenly stressed, thus affecting the laying quality.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] like Figure 1 and 2 As shown in the figure, the composite material fully automatic tape laying equipment equipped with a tape pressing roller device provided in this embodiment is Figure 1 It includes a compaction support assembly 1 and a strip material placement plate 5 for fixing the equipment, and a strip material pressing roller device arranged on the compaction support assembly 1, and the strip material pressing roller device includes a pressing roller assembly 3 and a pressing shoe assembly 2.

[0036] like Figure 2 As shown, the pressure roller assembly 3 includes a first telescopic assembly 31 , a pressure roller supporting rotating shaft 32 , a first pressure roller rod 33 , a second telescopic assembly 34 , a second pressure roller rod 35 , a pressure roller wheel 36 and a pressure roller mounting seat 37 .

[0037] More specifically, the tail end of the first telescopic component 31 is installed on the pressure shoe guide rail mounting seat, the starting end of the first telescopic component 31 is hinged to one end of the first pressure roller rod 33 to form a swing pair, the pressure roller support rotating shaft 32 and the first pressure roller rod 33 are hinged to form a rotation pair, the pressure roller support rotating shaft 32 and one end of the second pressure roller rod 35 are hinged to form a rotation pair, the other end of the first telescopic component 31 is hinged to the tail end of the second telescopic component 34 to form a rotation pair, and the starting end of the second telescopic component 34 and the other end of the second pressure roller rod 35 and the pressure roller wheel 36 form a composite hinge.

[0038] like Figure 4 As shown, the pressure roller lays and compacts the material: the first telescopic component 31 extends, driving the first telescopic component 31 to rotate relative to the pressure roller support rotating shaft 32. When the first telescopic component 31 swings to a preset position, the first telescopic component 31 is fixed, and the second telescopic component 34 starts to extend, thereby driving the pressure roller 36 to adjust its position, so that the pressure roller 36 is in full contact with the surface of the material for compaction.

[0039] The pressure roller wheel 36 is wrapped with a layer of rubber on the outside. The characteristic of rubber deformation under stress makes the pressure roller device suitable for compacting irregular curved surfaces on paving tools. Another main function of the pressure roller device is to separate the tailings of the material strip laid on the tooling from the backing paper. The tailings must remain on the backing paper when cutting due to their shape (angle). At the same time, the pressure roller device can be divided into 150mm and 300mm bandwidths, which are suitable for 150mm and 300mm widths of strips respectively. When the bandwidth is 150mm, the slope is ≥1:5, and the slope height can reach 6mm; when the bandwidth is 300mm, the slope is ≥1:10, and the slope height can reach 6mm. The maximum pressure of the pressure roller at the paving head is ≥1000N (or 0.8MPa. If the pressure unit is selected, an equivalent calculation formula must be provided), and the pressure programming is adjustable and displayable.

[0040] This embodiment also provides a control method for using a belt pressing roller device provided in the above embodiment, and the specific process is as follows:

[0041] like Figure 5 As shown, the complete pressure shoe assembly is driven down by the cylinder so that the pressure shoe piece is in full contact with the surface of the workpiece, and the pressure roller device is in a switching state between the pressure shoe and the pressure roller;

[0042] like Figure 6 As shown, after the pressure shoe assembly 2 is in full contact with the workpiece, the first telescopic assembly 31 of the pressure roller device contracts, driving the first pressure roller rod 33 to rotate relative to the pressure roller wheel 36. When the first pressure roller rod 33 swings to a preset position, the first pressure roller rod 33 is fixed, and the second telescopic assembly 34 starts to contract, thereby driving the second pressure roller rod 35 to rotate, and then driving the pressure roller support rotating shaft 32 to lift up and leave the workpiece surface.

[0043] When the device provided in this embodiment uses a roller device for compaction, the entire roller device is equipped with a guide rail in the Z-axis direction, so that it can adapt to the changes in the paving surface curve and ensure that the paving pressing force is stable within the corresponding range of the programmed value. In this way, the strip material can be accurately laid on the flat or gently curved parts with a large surface area such as wall panels and skins.

[0044] In addition, the terms "upper", "lower", "inner", "outer", "front", "rear" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. Unless otherwise specifically stated, the relative steps, numerical expressions and values ​​of the components and steps described in these embodiments do not limit the scope of the present invention.

[0045] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.

[0046] Finally, it should be noted that the above-described embodiments are only specific implementations of the present invention, which are used to illustrate the technical solutions of the present invention, rather than to limit them. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
