Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber prepreg laying equipment, and in particular to a thermosetting prepreg carbon fiber laying device. Background Technology

[0002] Thermosetting prepregs are composite materials made of carbon fiber and thermosetting resins (such as epoxy resin, phenolic resin, etc.). These materials have advantages such as high strength, low density, and fatigue resistance, making them the core materials for lightweight and high-performance structural components. They are mainly used in aerospace, new energy, high-end transportation, precision manufacturing and other fields with high requirements for lightweight and high performance.

[0003] Traditional thermosetting prepreg carbon fiber layup equipment mostly uses a single feeding mechanism. Due to the fixed length limitation of the prepreg tape, the machine must be stopped and a new roll must be replaced when a roll of material is used up. During this period, manual loading and unloading of the roll, joint alignment and tension recalibration are required, which causes production continuity interruption and short effective working time per shift. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a thermosetting prepreg carbon fiber laying device, which aims to improve the problem that most traditional thermosetting prepreg carbon fiber laying devices adopt a single feeding mechanism. Due to the fixed length limitation of the prepreg tape, when a roll of material is used up, the machine must be stopped to replace the new roll. During this period, manual loading and unloading of the roll, joint alignment and tension recalibration are required, which causes the interruption of production continuity and short effective working time per shift.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermosetting prepreg carbon fiber laying device, comprising a mounting plate, wherein a feeding mechanism, a conveying mechanism, a bonding mechanism, a cutting assembly, and a pressing mechanism are mounted on the side of the mounting plate; a material preparation threaded column and a first threaded column are fixedly connected to the side of the mounting plate; a first driving gear is rotatably connected to the outer side of the material preparation threaded column; a first material tray is disposed on the outer side of the first driving gear; a first driven gear is rotatably connected to the side of the first threaded column; a first collecting tray is disposed on the side of the first driven gear; the tooth ends of the first driving gear and the first driven gear are meshed with each other; a fixed turntable is threadedly connected to the outer side of both the material preparation threaded column and the first threaded column; an output mechanism is fixedly connected to the bottom side of the mounting plate; a heating rod is disposed diagonally below the output mechanism; and a second detection bracket and a first detection bracket are fixedly connected to the middle side of the mounting plate.

[0006] By adopting the above technical solution, a first detection bracket is installed on one side of the middle of the mounting plate, which can monitor the feeding mechanism in real time and output the remaining material signal. When the feeding mechanism is insufficient, it can output the signal to the output mechanism and the heating rod. The output mechanism drives the prepreg tape to rotate and contact the prepreg tape on the outer wall of the heating rod to form compression. Through the heating of the heating rod, the two prepreg tapes are bonded together end to end, thereby realizing the uninterrupted and rapid replacement of the prepreg tape. This solves the problem that most traditional thermosetting prepreg carbon fiber laying devices use a single feeding mechanism. Due to the fixed length limitation of the prepreg tape, when a roll of material is used up, the machine must be stopped to replace it with a new roll. During this period, manual loading and unloading of the roll, joint alignment and tension recalibration are required, which causes interruption of production continuity and short effective working time per shift.

A second collection tray is provided on the side of the second driven geared disc. Fixed turntables are threadedly connected to the outer sides of both the second and third threaded posts.

[0012] Preferably, the bonding mechanism includes an ultrasonic generator, the top of which has heat dissipation holes, the bottom output end of which is provided with a connecting pipe, the other end of which is provided with an ultrasonic probe, the bottom of which is arc-shaped, the top of which is fixedly connected with a third support block, and the side of which is fixedly connected to the bottom side of the mounting plate.

[0013] Preferably, a fixing ring is fixedly connected to the top of the mounting plate, and a fixing hole is opened on the top of the fixing ring for connecting the robotic arm.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a first detection bracket is installed on one side of the middle part of the mounting plate, which can monitor the feeding mechanism in real time and output the remaining material signal. When the feeding mechanism is insufficient, it can output the signal to the output mechanism and the heating rod. The output mechanism drives the prepreg tape to rotate and contact the prepreg tape on the outer wall of the heating rod to form compression. Through the heating of the heating rod, the two prepreg tapes are glued together end to end, thereby realizing the uninterrupted and rapid replacement of the prepreg tape. This solves the problem that most traditional thermosetting prepreg carbon fiber laying devices use a single feeding mechanism. Due to the fixed length limitation of the prepreg tape, when a roll of material is used up, the machine must be stopped to replace the new roll. During this period, manual loading and unloading of the roll, joint alignment and tension recalibration are required, which causes the interruption of production continuity and short effective working time per shift.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a thermosetting prepreg carbon fiber laying device, including a mounting plate 1. A feeding mechanism, a conveying mechanism, a bonding mechanism, a cutting assembly, and a pressing mechanism are mounted on the side of the mounting plate 1. A material preparation threaded post 7 and a first threaded post 31 are fixedly connected to the side of the mounting plate 1. A first active gear disc 2 is rotatably connected to the outer side of the material preparation threaded post 7. A first material tray 3 is disposed on the outer side of the first active gear disc 2. A first driven gear disc 4 is rotatably connected to the side of the first threaded post 31. A first collecting tray 5 is disposed on the side of the first driven gear disc 4. The tooth ends of the first active gear disc 2 and the first driven gear disc 4 are meshed with each other. A fixed turntable 6 is threadedly connected to the outer side of both the material preparation threaded post 7 and the first threaded post 31. An output mechanism is fixedly connected to the bottom side of the mounting plate 1. A heating rod 14 is disposed diagonally below the output mechanism. A second detection bracket 11 and a first detection bracket 10 are fixedly connected to the middle side of the mounting plate 1.

[0020] Specifically, the mounting plate 1 serves to support and fix the material; the feed threaded column 7 serves to fix and connect the mounting plate 1; the rotational connection between the first driving gear 2 and the feed threaded column 7 allows the first driving gear 2 to rotate around the center point of the cross-section of the feed threaded column 7; the meshing of the teeth of the first driving gear 2 and the first driven gear 4 causes the first driving gear 2 and the first driven gear 4 to rotate synchronously, and the rotation of the first driven gear 4 drives the first collecting plate 5 to rotate, which in turn winds and separates the release paper; the fixed turntable 6 serves to... The rotating connection between the feed threaded post 7 and the first threaded post 31 serves to fix the first material tray 3 and the first collection tray 5; the heating rod 14 heats the prepreg tape; the first detection bracket 10 outputs a material remaining signal, which, when the feeding mechanism has insufficient material, activates the output mechanism and the heating rod 14, causing the output mechanism to rotate and press the prepreg tape against the heating rod 14, where it is heated and bonded together; the second detection bracket 11 supports the prepreg; and the feeding mechanism ensures the prepreg tape is properly fed... The conveying mechanism delivers the prepreg tape to the bonding mechanism for bonding. The bonding mechanism presses and contacts the prepreg tape, adhering it to the workpiece. Simultaneously, the generated ultrasonic waves reduce air bubbles during bonding. A cutting component cuts the prepreg tape to the appropriate length. A clamping mechanism holds the prepreg tape in place, preventing the cut tape from falling off. Using this technical solution, a first detection bracket 10 is installed on one side of the middle of the mounting plate 1. This bracket monitors the feeding mechanism in real time and outputs a signal indicating the remaining material. When the feeding mechanism has insufficient material, it outputs a signal to the output device. The structure and heating rod 14 drive the prepreg tape to rotate through the output mechanism. The prepreg tape comes into contact with the outer wall of the heating rod 14 and is compressed. The heating rod 14 then heats the two prepreg tapes together end to end, thus enabling uninterrupted and rapid replacement of the prepreg tape. This solves the problem that traditional thermosetting prepreg carbon fiber laying devices mostly use a single feeding mechanism. Due to the fixed length limitation of the prepreg tape, the machine must be stopped and a new roll of material must be replaced when a roll of material is used up. During this period, manual loading and unloading of the roll, joint alignment, and tension recalibration are required, which causes interruption of production continuity and short effective working time per shift.

[0021] Reference Figure 1 The output mechanism includes a first motor 12, and a first main shaft 17 is rotatably mounted on the output end of the first motor 12. An eccentric column 13 is mounted on the side of the first main shaft 17 away from the first motor 12, and a fixing groove 37 is provided on the outer wall of the eccentric column 13.

[0022] Specifically, the first motor 12 provides rotational power to the first spindle 17; the first spindle 17 transmits the rotational power provided by the first motor 12 to the eccentric column 13; the eccentric column 13 has a fixing groove 37 that connects the prepreg strips; the rotation of the eccentric column 13 reduces the distance between it and the heating rod 14, causing the two prepreg strips to come into contact and be compressed; and the heating of the heating rod 14 causes the two prepreg strips to bond together end to end.

[0023] Reference Figures 1-2 The feeding mechanism includes a second threaded post 38, which is fixedly connected to one side of the mounting plate 1. A second geared disc 35 is rotatably connected to the outer side of the second threaded post 38. A second material tray 36 is provided on the outer side of the second geared disc 35. A third threaded post 39 is fixedly connected to the side of the mounting plate 1. A second driven geared disc 8 is rotatably connected to the side of the third threaded post 39. A second collection tray 9 is provided on the side of the second driven geared disc 8. A fixed turntable 6 is threadedly connected to the outer side of both the second threaded post 38 and the third threaded post 39. The tooth ends of the second geared disc 35 and the second driven geared disc 8 are meshed with each other.

[0024] Specifically, the second threaded post 38 supports the second geared disc 35; the rotatable connection between the second geared disc 35 and the second threaded post 38 allows the second material disc 36 to rotate around the center point of the cross-section of the second geared disc 35; the rotation of the second geared disc 35 causes the prepreg tape to rotate and unfold; the second material disc 36 holds the prepreg tape; the third threaded post 39 rotatably connects to the second driven geared disc 8; the second driven geared disc 8 mounts the second collecting disc 9, and the second collecting disc 9 facilitates winding. The release paper functions by meshing the teeth of the second toothed disc 35 and the second driven toothed disc 8, allowing them to rotate synchronously and separate the release paper on one side of the prepreg tape, which then wraps around the inside of the second collection tray 9. The outer sides of the second threaded column 38 and the third threaded column 39 are rotatably connected to the fixed turntable 6, which can fix the second material tray 36 and the second collection tray 9. The prepreg tape output from the second material tray 36 passes through the inner wall of the first detection bracket 10 and is connected to the prepreg conveying device. The prepreg tape output from the first material tray 3 passes through the inside of the second detection bracket 11 and is connected to the inner wall of the fixed groove 37 opened by the eccentric column 13.

[0025] Reference Figures 1-2 The conveying mechanism includes a second motor 18, a second main shaft 20 is rotatably mounted on the output end of the second motor 18, a second rotating wheel 19 is mounted on the side of the second main shaft 20 away from the second motor 18, a conveying bracket 15 is mounted on the bottom of the second rotating wheel 19, and a first rotating wheel 16 is rotatably connected to the middle of the conveying bracket 15.

[0026] Specifically, the second motor 18 generates rotational power; the second main shaft 20 at the output end of the second motor 18 transmits the rotational power; the rotation of the second main shaft 20 transmits the power to the second rotating wheel 19; the conveyor bracket 15 supports the rotation of the first rotating wheel 16; the rotation of the second main shaft 20 generates friction between the prepreg belt and the second main shaft 20, thereby moving the prepreg belt; as the prepreg belt moves, the rotation of the first rotating wheel 16 reduces the friction between the prepreg belt and the conveyor bracket 15, thus preventing scratches on the prepreg belt during production.

[0027] Reference Figures 1-2 The clamping mechanism includes a second support block 23, a second electric push rod 28 is provided on the bottom side of the second support block 23, a pressure plate 27 is provided at the output end of the second electric push rod 28, a support plate 26 is provided at the bottom of the pressure plate 27, and an inclined surface is provided on the side of the support plate 26 away from the first rotating wheel 16.

[0028] Specifically, the second support block 23 can fix the second electric push rod 28; the extension of the working output end of the second electric push rod 28 drives the pressure plate 27 to move towards the support plate 26, which, together with the support plate 26, can clamp the prepreg tape; the support plate 26 can place the prepreg tape, and the inclined surface on the side of the support plate 26 away from the first rotating wheel 16 can reduce the size of the device and make it easier to fit the prepreg tape.

[0029] Reference Figures 1-2 The cutting assembly includes a first support block 21, and a first electric push rod 22 is fixedly connected to the outer wall of the first support block 21. A triangular blade 29 is provided at the output end of the first electric push rod 22, and the triangular blade 29 is located diagonally above the support plate 26.

[0030] Specifically, the first support block 21 can fix the first electric push rod 22; the extension of the working output end of the first electric push rod 22 drives the triangular blade 29 to move towards the support plate 26, and the triangular blade 29 squeezes against the support plate 26 to cut the prepreg tape; the triangular shape of the triangular blade 29 can reduce the contact area and cut the prepreg tape more easily.

[0031] Reference Figures 1-3 The bonding mechanism includes an ultrasonic generator 32. The top of the ultrasonic generator 32 is provided with a heat dissipation hole 33. The bottom output end of the ultrasonic generator 32 is provided with a connecting pipe 30. The other end of the connecting pipe 30 is provided with an ultrasonic probe 25. The bottom of the ultrasonic probe 25 is arc-shaped. The top of the ultrasonic probe 25 is fixedly connected to a third support block 24. The side of the third support block 24 is fixedly connected to the bottom side of the mounting plate 1.

[0032] Specifically, the ultrasonic generator 32 generates ultrasonic waves, the heat dissipation hole 33 dissipates heat from the ultrasonic generator 32, the connecting pipe 30 transmits ultrasonic waves, the third support block 24 fixes the ultrasonic probe 25, and the ultrasonic probe 25 contacts the prepreg tape, which reduces internal air bubbles and improves the finished product qualification rate.

[0033] Reference Figure 1 A fixing ring 34 is fixedly connected to the top of the mounting plate 1. The top of the fixing ring 34 has a fixing hole for connecting the robotic arm. The interior of the first material tray 3 is used to wind the prepreg tape, and the interior of the first collection tray 5 is used to wind the release paper.

[0034] Specifically, the fixing holes provided by the fixing ring 34 enable convenient and quick connection of the robotic arm.

[0035] Working principle: When the first detection bracket 10 detects that the prepreg roll in the feeding mechanism is used up, it transmits a signal to make the first motor 12 and the heating rod 14 work simultaneously. The rotational power of the first motor 12 is transmitted to the eccentric column 13 through the first main shaft 17 at the output end. The eccentric column 13 drives the prepreg strip in the fixed groove 37 to rotate, so that it is squeezed with the prepreg strip on the heating rod 14. It is bonded together by the heating of the heating rod 14. The prepreg strip can be switched continuously. The working output end of the second motor 18 drives the second rotating wheel 19 to rotate. Through the friction generated with the prepreg strip, the prepreg strip is disengaged from the fixed groove 37 and continues to move. The movement of the prepreg strip drives the first material tray 3 to rotate. The rotation of the first material tray 3 drives the first active toothed disc 2 to rotate, thereby causing the first driven toothed disc 4 to rotate and drive the first collection tray 5 to rotate. The rotation of the first collection tray 5 can play the role of winding and separating the release paper. The prepreg strip is moved to the bonding mechanism through the conveying mechanism and is bonded by the movement of the robotic arm from top to bottom.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
