Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber bracket production and molding, and in particular to a carbon fiber bracket production and molding equipment and a manufacturing method. Background Art

[0002] Carbon fiber has become an indispensable material in the manufacture of UAVs due to its high specific strength, high specific stiffness, low weight, excellent corrosion resistance and heat resistance. These characteristics enable carbon fiber brackets to significantly reduce the weight of UAVs while meeting strength requirements, thereby improving flight efficiency, extending flight time and increasing load capacity; in the production process of carbon fiber brackets, the laying and curing of prepreg are the two core steps. Prepreg is a composite material that is pre-mixed with carbon fiber and other materials such as resin and partially cured. It provides a key basic material for the production of carbon fiber brackets; when it comes to the laying of prepreg for carbon fiber UAV frames, automatic tape laying machines are usually used as the preferred equipment. Automatic tape laying machines can quickly lay prepreg tapes to ensure accurate laying positions, while maintaining the tension and position stability of the prepreg tapes, thereby effectively avoiding the formation of wrinkles or bubbles.

[0003] In the prior art, there is a roller mechanism suitable for composite material curved surface laying, such as publication number CN111113939A, which includes: an independent pneumatic roller mechanism, and the upper and lower ends of the pneumatic cylinder barrel of the independent roller mechanism are respectively connected to the upper and lower ends of the cylinder base. Through multiple independent pneumatic roller mechanisms, the expansion and contraction amount and pressure of the pneumatic cylinder in each independent pneumatic roller mechanism can be controlled separately, so as to realize the composite material laying of multiple track curved surfaces at one time, greatly improving the laying efficiency and ensuring the laying quality.

[0004] In actual use, although it can adapt to carbon fiber brackets with different curvature rates, the prepreg is laid in multiple layers in an interlaced manner using multiple sets of separate cylinders, which has a high laying cost. In addition, after the pressure roller lays the material, it cannot be compacted to the prepreg tape and the frame surface in time, which easily leads to wrinkles and bubbles, affecting the molding effect of the carbon fiber bracket.

[0044] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] For example, see Figure 1-19 The present invention provides a technical solution: a carbon fiber bracket production and molding equipment, including a mounting support 1 and a swing support 12, both sides of the swing support 12 are fixedly connected with rotating pins 11, the swing support 12 is rotatably mounted on the mounting support 1 by rotating the pins 11, a prepreg laying mechanism 2 is arranged on the inner side of the swing support 12, the prepreg laying mechanism 2 includes a laying top plate 21, a laying roller mounting frame 22, a swing guard 25 and an auxiliary pressure roller 26, the lower end of the laying roller mounting frame 22 is rotatably connected with a prepreg laying roller body 221, both ends of the laying top plate 21 are respectively provided with a discharge trough 23 and a suction air nozzle 24, the discharge trough 23 and the suction air nozzle 24 are respectively mounted on both sides of the laying roller mounting frame 22, the swing guard 25 is rotatably mounted on both sides of the laying top plate 21, and the swing guard 25 is rotatably mounted on both sides of the laying top plate 21. The end of the movable guard frame 25 connected to the laying top plate 21 is provided with a swing amplitude locking component, and the auxiliary pressure roller 26 is provided with an elastic rolling component; the end of the laying roller mounting frame 22 away from the prepreg laying roller body 221 is provided with a limit frame plate 222, and the limit frame plate 222 is fixedly installed on the lower surface of the laying top plate 21, and the upper surface of the prepreg laying roller body 221 is slidably connected with the inner surface of the limit frame plate 222, and the inner bottom surface of the limit frame plate 222 is fixedly connected with a buffer spring 2211 and a telescopic sleeve, and the other ends of the prepreg laying roller body 221 and the telescopic sleeve are respectively fixedly connected with the upper end of the laying roller mounting frame 22; a soft baffle 241 is fixedly installed on the inner bottom surface of the swing guard frame 25, and the upper surface of the soft baffle 241 is movably abutted against the lower surface of the suction air nozzle 24;

[0046] In this embodiment, the mounting support 1 is connected to the driving assembly of the automatic tape laying machine, and the swing support 12 is installed at the lower end of the mounting support 1. The swing amplitude of the swing support 12 and the prepreg laying mechanism 2 as a whole is controlled by the rotating pin 11, so as to adapt to the brackets with different curved surfaces and change the laying angle at will. One end of the prepreg tape is sucked by the suction nozzle 24 and passes through the lower end of the prepreg laying roller 221 and the discharge trough 23 in sequence. When the mounting support 1 moves as a whole, the prepreg tape is tightly sucked by the suction nozzle 24. When it reaches the laying position, the laying top plate 21 is lowered as a whole, and the control of the telescopic part of the suction nozzle 24 is coordinated to make the prepreg at the bottom of the suction nozzle 24 close to the surface of the UAV bracket. Then, the laying top plate 21 is moved to ensure that the prepreg laying roller 221 makes the prepreg close to the bracket surface. It should be noted that the upper end of the laying roller mounting frame 22 is connected to a buffer spring 2211 and a telescopic sleeve, both of which are deformed when the prepreg laying roller body 221 shakes, so that the shaking force of the prepreg laying roller body 221 is weakened by the two, and the elastic deformation of the two can also be used to make the prepreg laying roller body 221 better adapt to the surface of the UAV bracket with different curvatures, ensure that the carbon fiber prepreg laying material is accurately attached to the surface of the UAV bracket, and improve the molding effect; adopt the mutual cooperation of the swing guard frame 25 and the auxiliary pressing roller 26, add the auxiliary rolling structure of the material strip after the prepreg laying roller body 221 is laid, and cooperate with the setting of the elastic rolling assembly, which not only meets the close fit between the material strip and the bracket, but also can synchronously adapt to different curved surfaces, and can also maintain a constant pressure for pressing the laying material and the bracket parts, further improving the molding effect of the carbon fiber bracket.

[0047] Embodiment 2, refer to the attached Figure 1-19On the basis of the first embodiment, in order to adjust the swing angle of the swing guard 25 and the auxiliary pressure roller 26: the swing guard 25 is a "U"-shaped plate structure, and the outer surfaces of both sides of the swing guard 25 are fixedly installed with convex plates 250, one side of the convex plate 250 is fixedly connected with a curved elastic wire 254, and the other end of the curved elastic wire 254 is fixedly connected with a swing arm 253; the swing arm 253 is fixedly connected with a central shaft 252, and the inner side of the central shaft 252 is rotatably connected with a fixed block 251, and the fixed block 251 is fixedly installed on the inner walls of both sides of the swing guard 25; the auxiliary pressure roller 26 is a hollow cylindrical structure, and the two ends of the auxiliary pressure roller 26 are respectively provided with connecting shafts 26 0, the connecting shaft 260 penetrates the inner wall of the lower end of the swing arm 253 and is rotatably connected to the inner wall of the swing arm 253, and the connecting shaft 260 is provided with two groups, and a through hole is opened on the inner wall of one group of connecting shafts 260, and an air inlet pipe 2630 is fixedly connected to the inner surface of the through hole, and a micro air pump 26301 is provided at the input end of the air inlet pipe 2630; the output end of the air inlet pipe 2630 is sealed and connected with an extrusion airbag 263, and the extrusion airbag 263 is arranged in the cavity of the auxiliary pressure roller 26, and a plurality of groups of exhaust fine tubes 2631 are connected through the inner wall of the extrusion airbag 263, and the plurality of exhaust fine tubes 2631 are distributed in a circular array about the horizontal central axis of the auxiliary pressure roller 26;

[0048] In this embodiment, the swing guard 25 is installed on one side of the laying roller mounting frame 22, one end of the swing arm 253 is connected to the auxiliary pressure roller 26, and the other end is connected to the surface of the convex plate 250 through the curved elastic wire 254. At this time, the swing arm 253 forms a lever. When the auxiliary pressure roller 26 contacts the surface of the bracket, the curved elastic wire 254 will produce different degrees of deformation, which is convenient for adapting to surfaces with different curvatures. In addition, it can also weaken the jitter of the auxiliary pressure roller 26 when rolling, reduce vibration damage between components, and extend the overall service life; here, the auxiliary pressure roller 26 is optimized as a whole, and a cavity structure is adopted. The extrusion airbag 263 is installed. When the input end of the air inlet pipe 2630 is connected to the micro air pump 26301, the air source is delivered to the inside of the extrusion airbag 263, and the inflated extrusion airbag 263 is used to achieve a constant pressure in the circumferential direction. It is worth noting that a plurality of groups of fine exhaust tubes 2631 are passed through the inner wall of the extrusion airbag 263. When the extrusion airbag 263 is continuously squeezed, the gas inside the extrusion airbag 263 is forced to be ejected outward through these exhaust tubes 2631, so that the prepreg can be assisted in cooling and the dust on the surface can be blown away.

[0049] It is worth noting that by adjusting the swing amplitude of the swing guard 25 and the auxiliary pressure roller 26, multiple effects can be achieved, such as Figure 4 As shown, the swing guard 25 drives the auxiliary pressure roller 26 to swing outward at an angle of 60°. At this time, the auxiliary pressure roller 26 can be used as an auxiliary pressure roller after the prepreg laying roller body 221 is laid; Figure 5As shown, at this time, the swing guard 25 tends to be perpendicular to the laying top plate 21, and the auxiliary pressure roller 26 is lower than the lowest plane of the prepreg laying roller body 221. When the mounting support 1 moves as a whole, the compaction between the material belt and the UAV bracket can be achieved independently. The soft baffle 241 on the inner side of the swing guard 25 protects the bottom of the suction nozzle 24 to prevent dust from entering the output hole of the suction nozzle 24 when the auxiliary pressure roller 26 rolls the surface of the material belt and causing blockage; Figure 7 As shown, when the equipment is in an idle state and not working, the swing guard frame 25 still tends to be in a vertically aligned state, and the auxiliary pressure roller 26 reaches the bottom of the prepreg laying roller body 221, which can protect the bottom side of the prepreg laying roller body 221, and can abut the material tape when the material tape and the suction nozzle 24 accidentally fall off, to prevent the material tape from being scattered.

[0050] Embodiment 3, refer to the attached Figure 1-19 On the basis of the second embodiment, in order to achieve the stability of the rolling of the support surface by the rolling ring plate 261: the elastic rolling assembly includes a rolling ring plate 261 and a squeezing column 262, the squeezing column 262 is a rectangular block structure and a circular array is distributed on the outer ring surface of the auxiliary pressing roller 26, and the inner wall of the auxiliary pressing roller 26 is provided with an avoidance groove 2600 that is slidably matched with the outer surface of the squeezing column 262, and the outer surface of the squeezing column 262 is fixedly connected to the inner ring surface of the rolling ring plate 261 ; A splicing cover net 2610 is arranged on the rolling ring plate 261, and elastic support members are respectively arranged on both sides of the splicing cover net 2610, and the elastic support members include a double-layer ring plate 2611 and an A-type elastic block 2612, the double-layer ring plate 2611 is fixedly installed on the inner wall of the rolling ring plate 261, and the A-type elastic block 2612 is fixedly installed on the inner side of the double-layer ring plate 2611, and the A-type elastic block 2612 is arranged in a circular array about the central axis of the double-layer ring plate 2611;

[0051] In this embodiment, multiple groups of extrusion columns 262 penetrate the auxiliary pressing roller 26, and are arranged in an array on the inner ring of the rolling ring plate 261. When the extrusion airbag 263 is inflated, the rolling ring plate 261 can achieve a pressure balance effect when it contacts the surface of the prepreg paving material with different curvatures, ensuring that the rolling ring plate 261 can obtain the same pressure in the circumferential direction without separate adjustment; and can adapt to processing surfaces with different curvatures, effectively contact the surface of the prepreg paving material and the bracket, and provide a constant pressing force, thereby improving the stability of the pressing material; and it should be noted that, with reference to Figure 13-14 As shown, an elastic support piece is added to the rolling ring plate 261, and the double-layer ring plate 2611 and the A-type elastic block 2612 are arranged together, which can not only achieve balanced support for the rolling ring plate 261 during rolling and enhance the stability of the UAV bracket forming, but also reduce the shaking of the auxiliary pressure roller 26 and enhance the stability of the rolling effect.

[0052] Embodiment 4, refer to the attached Figure 1-19 On the basis of the third embodiment, in order to realize the unlocking and locking of the swing guard 25 and the auxiliary pressure roller 26 with different swing amplitudes: the swing amplitude locking assembly includes a fixed pin 27 and a fixed toothed ring 28, the fixed pin 27 is fixedly mounted on the laying top plate 21, the fixed toothed ring 28 is fixedly mounted on the upper outer surface of the swing guard 25, a limiting groove 270 is provided at one end of the outer side of the fixed pin 27, a rotating buckle 271 is rotatably mounted on the central inner surface of the fixed pin 27, and a buckling groove is provided at one end of the outer side of the rotating buckle 271; side arc grooves 2710 are symmetrically provided on the inner walls of both sides of the rotating buckle 271, and the inner surface of the side arc groove 2710 is movably embedded with The arc-shaped end plate 2731 has a movable block 273 fixedly connected to the other end of the arc-shaped end plate 2731, and a locking cone plate 2732 fixedly connected to one end of the movable block 273 away from the arc-shaped end plate 2731, and the outer surface of the locking cone plate 2732 is movably engaged with the inner tooth groove of the fixed gear ring 28; the outer surface of the movable block 273 is fixedly connected to a connecting square plate 274, and one side of the connecting square plate 274 is fixedly connected to a connecting spring piece 2741, and the other end of the connecting spring piece 2741 is fixedly connected to a connecting protrusion 272, and the connecting protrusion 272 is fixedly installed on the inner wall of the limiting groove 270, and the other side of the connecting protrusion 272 is movably abutted against the outer surface of the arc-shaped end plate 2731;

[0053] In this embodiment, a swing range locking component is added at the connection position between the swing guard 25 and the laying top plate 21. Figure 6 For example, when the swing guard 25 stops, the operator puts his finger into the buckling groove on the outside of the rotating buckle 271, and rotates the side arc groove 2710 in the horizontal state by 90 degrees, so that the opening direction of the two sets of side arc grooves 2710 is in a vertical state. At this time, the rounded section of the arc end plate 2731 is pushed out by the side arc groove 2710, and the arc end plate 2731 drives the movable block 273 and the locking cone plate 2732 to move to both sides, so that the locking cone plate 2732 is inserted between the teeth of the fixed gear ring 28. At this time, when the movable block 273 moves, the connecting square plate 274 moves synchronously, and drives the connecting spring piece 2741 to move outward. When the locking cam 2732 is engaged with the locking cam 2734, the locking cam 2735 is engaged with the locking cam 2736. When the locking cam 2736 is engaged with the locking cam 2737, the locking cam 2738 is engaged with the locking cam 2739.

When it reaches the laying position, the laying top plate 21 is lowered as a whole, and the prepreg at the bottom of the suction nozzle 24 is tightly attached to the surface of the UAV bracket in coordination with the control of the telescopic part of the suction nozzle 24.
