Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of high-performance composite material component manufacturing, and specifically relates to a laying device for preparing large components with high-performance fiber thermoplastic prepreg tapes. Background Art
[0002] With the rapid development of aerospace, rail transit, wind power, etc., the demand for large load-bearing components is increasing rapidly. For example, aircraft skins, rail transit car bodies, wind power blades, etc. all require large load-bearing components. At present, thermosetting composite materials are widely used to make large components. However, thermosetting composite materials usually take a long time to form, and the storage of materials has strict time requirements, resulting in high production costs and a high rate of defective products. Moreover, since thermosetting composite materials cannot be recycled and reused, it is difficult to handle large components in the later stage.
[0003] In recent years, with the continuous maturity of high-performance fiber-reinforced thermoplastic prepreg technology, the preparation of large-scale load-bearing components has begun to use high-performance fiber-reinforced thermoplastic prepregs on a large scale. Since the mobility of thermoplastic resin molecular chains is higher than that of thermosetting resins, the toughness of thermoplastic resins is generally higher. For example, the specific strength, heat resistance, impact resistance, and wear resistance of continuous carbon fiber reinforced thermoplastic resin composites far exceed those of thermosetting carbon fiber composites. Various glass fiber and carbon fiber thermoplastic prepregs have high strength and impact resistance. At the same time, the use of high-performance fiber-reinforced thermoplastic prepregs to prepare large-scale load-bearing components has a short molding cycle and high production efficiency.
[0004] High-performance fiber thermoplastic prepreg is an advanced composite material, which is composed of high-performance fibers (such as carbon fiber, glass fiber or aramid fiber, etc.) and a thermoplastic resin matrix. Due to its high performance, thermoplasticity, formability, lightweight and other characteristics, high-performance fiber thermoplastic prepreg is often used in aerospace, automobile, sports equipment, construction and other fields. It can be used to manufacture high-strength, lightweight structural parts to improve product performance and efficiency.
[0005] However, since high-performance fiber-reinforced thermoplastic prepregs are formed in layers in an autoclave when forming large components, the autoclave size and composite pressure requirements are high. In addition, structural reinforcement cannot be added directly, which hinders the application of thermoplastic prepregs in large load-bearing components. Utility Model Content

DETAILED DESCRIPTION
[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0032] Embodiment 1:
[0033] like Figure 1-Figure 3As shown, a laying device for preparing large components from high-performance fiber thermoplastic prepreg tapes includes a conveying component and a laying component, the conveying component includes four supporting legs 100, and the four supporting legs 100 are distributed in a four-cornered rectangle, a rotating rod 101 is rotated between the two supporting legs 100 corresponding to the left and right sides, one end of the rotating rod 101 on the front side is externally connected to a motor, a conveyor belt 102 is arranged between the outer sides of the two rotating rods 101 on the front and rear sides, a fixing rod 103 is arranged between the two supporting legs 100 corresponding to the front and rear sides, and a slitting component is commonly arranged at the upper ends of the two fixing rods 103, and the front ends of the two supporting legs 100 on the front side are both provided with extension arms 104, and the front ends of the two extension arms 104 are commonly fixed with a traction frame 105, a mechanical arm is installed in the middle of the traction frame 105, a laying disc 106 is hinged at the end of the mechanical arm, and a laying component is arranged at the lower end of the laying disc 106;
[0034] The laying assembly includes a plurality of hot pressing rollers 107, and a plurality of evenly distributed material guide grooves 108 are opened inside the laying disk 106, and each material guide groove 108 runs through the upper and lower ends of the laying disk 106. A plurality of material guide boxes 109 are provided at the lower end of the laying disk 106, and each material guide box 109 is connected to the lower port of the corresponding material guide groove 108. A plurality of N-shaped mounting frames 110 are evenly fixed to the lower end of the laying disk 106, and each N-shaped mounting frame 110 has a mounting groove 111 symmetrically opened on the lower side, and a mounting rod 112 is installed between two mounting grooves 111. Each hot pressing roller 107 is respectively arranged on the outer side of the corresponding mounting rod 112, and a gap is left between the opening of the material guide box 109 and the hot pressing roller 107.
[0035] The conveying assembly can convey the high-performance fiber thermoplastic prepreg tape to facilitate subsequent processing, wherein the support foot 100 provides support for the conveying assembly to be placed on the ground, and the rotating rod 101 connects the two corresponding supporting feet 100 on the left and right sides, so that the conveying belt 102 can be sleeved on the outside of the two rotating rods 101, and the rotating rod 101 is rotated by the motor to provide a power source, so that the conveying belt 102 can convey the high-performance fiber thermoplastic prepreg tape, and the fixing rod 103 connects the two corresponding supporting feet 100 in front and behind, making the entire conveying assembly more stable; the slitting assembly can be used to cut the high-performance fiber thermoplastic prepreg tape conveyed on the conveying belt 102 The high-performance fiber thermoplastic prepreg tape can be cut to obtain the high-performance fiber thermoplastic prepreg tape of suitable width required by the staff; the hydraulic rod and the line can be installed inside the mechanical arm, so that the mechanical arm can be moved to realize the laying operation; after cutting, the high-performance fiber thermoplastic prepreg tape can be separated from the upper surface of the conveyor belt 102 through the traction frame 105, and then the high-performance fiber thermoplastic prepreg tape is passed through the inside of the guide groove 108. The high-performance fiber thermoplastic prepreg tape has a certain viscosity after heating, so it is abutted against the outer surface of the hot pressing roller 107 through the guide box 109, so that a large component can be formed;
[0036] When laying large components: after the high-performance fiber thermoplastic prepreg tape passes through the guide groove 108, it can be guided to abut against the hot pressing roller 107 through the feeding box 109. When the hot pressing roller 107 contacts the laid panel, the hot pressing roller 107 drives the installation rod 112 to move upward along the installation groove 111 until the hot pressing roller 107 abuts against the opening at the lower end of the feed box 109. At the same time, the high-performance fiber thermoplastic prepreg tape will also contact the hot pressing roller 107 and become soft due to heat, which makes it convenient for the hot pressing roller 107 to lay the high-performance fiber thermoplastic prepreg tape on the panel. Under the control of the mechanical arm, the laying disk 106 can directly rely on the hot pressing roller 107 in the corresponding direction for laying. Large components can also be laid without rotating the hot pressing roller 107. This not only makes laying more flexible and efficient, but also allows laying large components of any shape without restrictions.
[0037] In this embodiment, by setting the hot pressing rollers 107 in different directions, when laying large components, more targeted laying can be achieved in various directions. At the same time, the high-performance fiber thermoplastic prepreg tape is divided into different widths through the slitting assembly, so that the hot pressing roller 107 can lay high-performance fiber thermoplastic prepreg tape of any width. This not only improves the laying efficiency, but also allows the laying of any large components without restriction.
[0038] Embodiment 2:
[0039] Based on the first embodiment, the components of the laying device are further described. Figure 3-Figure 6 As shown, the slitting assembly includes two support plates 200, and the two support plates 200 are fixedly connected to the upper ends of the two fixed rods 103 respectively. A cross bar 201 is installed on the rear side between the two support plates 200, and a plurality of evenly distributed abutment blocks 202 are fixed to the lower end of the cross bar 201, and a gap is left between the lower end of each abutment block 202 and the upper end surface of the conveyor belt 102. A cover plate 203 is rotated on the front side between the two support plates 200, and an I-shaped slide groove 204 that passes through the cover plate 203 from top to bottom is opened inside the cover plate 203, and a plurality of I-shaped sliders 205 slide inside the I-shaped slide groove 204, and a plurality of dividing pieces 206 are provided at the lower end of each I-shaped slider 205, and each dividing piece 206 is dispersedly inserted between the corresponding two abutment blocks 202.
[0040] A lifting groove 207 is provided at the rear side of the upper end of the cover plate 203 , and a matching buckle 208 is provided between the rear side of the lower end of the cover plate 203 and the upper end of the cross bar 201 .
[0041] The middle part of the traction frame 105 is set in a circular state, and a plurality of evenly distributed through slots 300 are opened at the front end of the traction frame 105, and a round rod 301 is rotated inside each through slot 300.
[0042] The robot arm includes a primary arm 302, the rear end of which is hinged to the front end of the traction frame 105, the front end of the primary arm 302 is hinged to the secondary arm 303, the front end of the secondary arm 303 is rotatably connected to the laying disk 106, and the interiors of the primary arm 302 and the secondary arm 303 are both set to be hollow.
[0043] Protective plates 304 are evenly arranged on the lower inner sides of the primary arm 302 and the secondary arm 303 .
[0044] Connecting rods 305 are symmetrically arranged on the outer sides of the hinges of the primary arm 302 and the secondary arm 303 . The two connecting rods 305 are jointly provided with a guide plate 306 . A plurality of guide grooves 307 are formed at the front end of the guide plate 306 .
[0045] The edges of each guide groove 307 are configured to be arc-shaped.
[0046] In this embodiment, the cover plate 203 and the cross bar 201 can be locked to a certain extent by matching the buckles 208 to each other, so as to prevent the cover plate 203 from tilting up and affecting the cutting of the high-performance fiber thermoplastic prepreg tape, and the staff can also flip the cover plate 203 through the lifting groove 207, so that the staff can push the I-shaped slider 205 to slide inside the I-shaped slide groove 204 to adjust the distance between each split piece 206. When it moves to a suitable position, when the cover plate 203 is covered, each split piece 206 will be stuck between two adjacent abutment blocks 202, so that the split piece 206 can be restricted, so that the high-performance fiber thermoplastic prepreg tape can be cut to obtain high-performance fiber thermoplastic prepreg tapes of different widths, and it is also convenient to replace the split piece 206;
[0047] The first arm 302 and the second arm 303 are both hollow inside. In the prior art, hydraulic telescopic rods and lines can be installed inside to ensure that the mechanical arm can move and realize the movement of laying. The protective plate 304 can not only conveniently protect the components inside the first arm 302 and the second arm 303, but also prevent the lines from being exposed and affecting the laying.
[0048] The traction frame 105 and the guide plate 306 can both guide the moving direction of the high-performance fiber thermoplastic prepreg tape. After the high-performance fiber thermoplastic prepreg tape is divided, it can be abutted against the round rod 301 through the through groove 300. The round rod 301 can reduce the friction between the high-performance fiber thermoplastic prepreg tape and the high-performance fiber thermoplastic prepreg tape, so that the high-performance fiber thermoplastic prepreg tape can pass through the traction frame 105 faster. After the high-performance fiber thermoplastic prepreg tape passes through the guide groove 307, the direction of the high-performance fiber thermoplastic prepreg tape can be changed, so that the high-performance fiber thermoplastic prepreg tape will not contact the outside of the robot arm, causing damage to the high-performance fiber thermoplastic prepreg tape;
[0049] The edges of the guide grooves 307 are all configured to be arc-shaped, which can prevent damage to the high-performance fiber thermoplastic prepreg tape and affect the laying effect.
