Description

Technical Field

[0001] This application relates to the technical field related to the laying of carbon fiber prepregs, and in particular, to a laying device for carbon fiber prepregs. Background Art

[0002] Carbon fiber prepreg is a high-performance composite intermediate product. It is a semi-finished product pre-impregnated with carbon fiber reinforcing materials and a resin matrix, and has high strength and modulus, low density, better heat resistance and corrosion resistance, and good fatigue performance. Therefore, it is widely used in the fields of aerospace, automotive industry, sports equipment, and medical devices;

[0003] In the existing market, in order to improve the laying efficiency of carbon fiber, an automated laying device is generally used to carry out the laying work of carbon fiber prepregs. Specifically, first, the rolled carbon fiber prepreg is set above the material roll disk. Through the rotation of the material roll disk, the unwinding work of the carbon fiber prepreg is completed. During unwinding, the carbon fiber prepreg will be separated from the release paper on its surface. The separated release paper reaches the release paper winding disk for winding, and the unwound carbon fiber prepreg will successively pass through the first pressing assembly and the cutting assembly and enter the inside of the guiding assembly for guiding work, and then pass through the guiding assembly to reach the surface of the workpiece to be laid. At this time, the second pressing assembly is controlled to descend to extrude the unwound carbon fiber prepreg. After that, the external robotic arm drives the entire fixing plate to move, and in cooperation with the continuous unwinding work of the material roll disk, the purpose of completely laying the surface of the workpiece will be achieved, such as the laying process disclosed in a thermosetting prepreg carbon fiber laying device with the application number 202411226355.2.

[0004] However, before the above-mentioned laying device performs laying, no corresponding cleaning mechanism is provided. Although the workpiece is cleaned before being placed on the workbench, due to the complex processing environment, the surface of the workpiece on the workbench will still be affected by the external environment. Therefore, it will cause the prepreg to not fit tightly with the surface of the workpiece, which will result in voids or bubbles between the prepreg and the mold, affecting the surface quality and dimensional accuracy of the product. Impurities will also form an isolation layer between the prepreg and the mold, resulting in difficult demolding, and may even damage the surface of the product. Surface impurities will also interfere with the bonding between the fiber and the resin, reducing the strength and modulus of the composite material. For example, bubbles or voids will become stress concentration points, and cracks are likely to occur and expand when stressed. Surface defects will reduce the fatigue resistance of the composite material. Under cyclic loading, these defects will accelerate the formation and expansion of cracks, shortening the service life of the product. And the product quality problems caused by the above problems will lead to rework of the product, such as grinding, repairing, etc., which will increase the production cost, production cycle, and the rejection rate.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0034] One preferred embodiment of this application is as Figures 1 to 10 shown

[0035] The above describes a laying device for a carbon fiber prepreg of this application, including a fixing plate 1. At the middle position of the top end of the fixing plate 1, a connecting piece 2 for connecting with an external robot is provided. On both sides of the connecting piece 2, a material roll disc 3 and a release paper winding disc 4 are respectively arranged. The material roll disc 3 and the release paper winding disc 4 are respectively installed on both sides of the top end of the fixing plate 1. The material roll disc 3 is used for placing the prepreg main body 5, and the release paper winding disc 4 is used for recycling the release paper pasted on the outside of the prepreg main body 5. At the bottom of the fixing plate 1, a first pressing assembly 6, a cutting assembly 7, a guiding assembly 8 and a second pressing assembly 9 are successively arranged. The first pressing assembly 6 is arranged on the side biased towards the material roll disc 3. At the bottom of the guiding assembly 8, a cleaning assembly 10 is provided for wiping and cleaning the surface of the workpiece to be laid. On the outside of the guiding assembly 8, a collecting assembly 11 is arranged, and the collecting assembly 11 is installed on the back of the fixing plate 1. The collecting assembly 11 is used for collecting the impurities after being cleaned by the cleaning assembly 10.

[0036] The first pressing assembly 6 includes a first pressing cylinder 61, a first moving roller 62 and a fixed roller 63. The first pressing cylinder 61 is connected to one side of the fixing plate 1, and the bottom of the first pressing cylinder 61 is connected to the first moving roller 62 by a bearing. Below the first moving roller 62, a fixed roller 63 is provided, and the middle shaft of the fixed roller 63 is connected to one side of the fixing plate 1 by a bearing.

[0037] The cutting assembly 7 includes a second pressing cylinder 71 and a cutting knife 72. The cutting knife 72 is arranged at the bottom of the second pressing cylinder 71, and the second pressing cylinder 71 is connected to one side of the fixing plate 1. The second pressing assembly 9 includes a third pressing cylinder 91 and a second moving roller 92. The bottom of the third pressing cylinder 91 is connected to the second moving roller 92 by a bearing, and the third pressing cylinder 91 is connected to one side of the fixing plate 1.

[0038] The present application provides a laying device for carbon fiber prepreg with a cleaning component 10. Specifically, when in use, first, an external robotic arm is connected to the connecting member 2 on the fixed plate 1. At this time, the motor outside the material reel 3 controls the rotation of the material reel 3 to unwind the prepreg main body 5. After unwinding, the prepreg main body 5 is separated from the release paper outside it. The separated release paper is adhered to the outside of the release paper winding reel 4. By controlling the rotation of the release paper winding reel 4 under the action of the motor, the winding of the release paper can be completed. The top of the separated prepreg main body 5 will sequentially pass through the bottom of the first moving roller 62 and the bottom of the cutting knife 72, and then after being guided by the guiding component 8, it reaches the bottom of the second moving roller 92. At this time, control the third pressing cylinder 91 to start, so that it drives the second moving roller 92 to descend, pressing the guided prepreg main body 5 against the surface of the workpiece. At this time, control the external robot to drive the connecting member 2 and the entire fixed plate 1 to move according to the set procedure, which will drive the second moving roller 92 to continuously move on the surface of the workpiece, completing the automatic pressing and laying work of the prepreg main body 5. When moving and laying, since the cleaning component 10 is provided at the bottom of the guiding component 8, when the robot drives the entire device to move towards the laying position of the workpiece, the cleaning component 10 can clean the surface of the workpiece in advance, thereby cleaning impurities such as dust, oil stains, and debris on the surface of the workpiece. After that, the impurities are sucked and collected by the collecting component 11, ensuring that the surface to be laid of the prepreg main body 5 is in a clean state, thereby ensuring the laying quality.

[0039] When it is necessary to cut the prepreg main body 5 after laying is completed, at this time, control the first pressing cylinder 61 to descend, so that it drives the first moving roller 62 to descend, pressing the prepreg main body 5 between the first moving roller 62 and the fixed roller 63, making the prepreg main body 5 in a taut state at this time. Then, control the second pressing cylinder 71 to descend, so that it drives the cutting knife 72 to descend, completing the cutting work of the prepreg main body 5. Since there is still part of the prepreg main body 5 in the guiding component 8 after cutting, control the robot to continue moving, and the laying work of the remaining prepreg main body 5 will be completed.

[0040] As a further preference of this embodiment, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 9 and Figure 10As shown, the guiding component 8 includes an upper guiding plate 81 and a lower guiding plate 82. The lower guiding plate 82 is arranged below the upper guiding plate 81. Upper side blocks 83 are fixed on both sides of the upper guiding plate 81. Lower side blocks 84 are arranged on both sides of the lower guiding plate 82. At the top of the lower side block 84, a "U"-shaped connecting sliding frame 86 is fixed, and the connecting sliding frame 86 slides inside the upper side block 83.

[0041] An adjusting mechanism is arranged inside the connecting sliding frame 86, and it includes a rotating screw 87 and a rotating gear 88. The rotating gear 88 is arranged outside the rotating screw 87, and the rotating gear 88 meshes with the tooth blocks on one side wall inside the connecting sliding frame 86. The upper part of the rotating screw 87 is controlled to rotate by a rotating control component 85, and the rotating control component 85 is arranged inside the fixed cover at the top of the upper guiding plate 81.

[0042] The rotating control component 85 includes a rotating handle 851, a driving pulley 852, a connecting belt 853 and a driven pulley 854. The bottom of the rotating handle 851 is coaxially connected with the driving pulley 852. Two connecting belts 853 are arranged outside the driving pulley 852, and the driven pulleys 854 are respectively arranged at the tops of the two connecting belts 853. At the bottom of the driven pulley 854, a rotating screw 87 coaxially connected with it is arranged.

[0043] Specifically, when the prepreg main body 5 gets stuck between the upper guiding plate 81 and the lower guiding plate 82, it is necessary to separate the upper guiding plate 81 and the lower guiding plate 82 to complete the maintenance work. At this time, it is necessary to rotate the rotating handle 851. When the rotating handle 851 rotates, it will drive the driving pulley 852 coaxially connected with it to rotate. With the arrangement of the connecting belt 853, the driven pulleys 854 on both sides will rotate. When the driven pulley 854 rotates, it will drive the rotating screw 87 coaxially connected with it to rotate. When the rotating screw 87 rotates, it will mesh with the rotating gear 88, causing the rotating gear 88 to rotate. When it rotates, it will mesh with the tooth blocks on the inner wall of the connecting sliding frame 86. At this time, the connecting sliding frame 86 descends in the chute inside the upper side block 83. Thus, the connecting sliding frame 86 drives the lower side block 84 to descend, achieving the purpose of driving the lower guiding plate 82 to descend. Thereby, the lower guiding plate 82 is separated from the upper guiding plate 81, which facilitates the maintenance and combing work on the stuck prepreg main body 5.

[0044] As a further preference of this embodiment, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、Figure 6 and Figure 7 As shown in Figure 7 , the cleaning component 10 includes a fixed rod body 101, a driving component 102, a rotating cylinder 103, and a fixed protective cover 104. A driving component 102 is arranged on the outer side of the fixed rod body 101, and the driving component 102 is used to control the up and down movement of the fixed rod body 101. At the bottom of the fixed rod body 101, a fixed protective cover 104 with a two-thirds circular structure is integrally installed, and a rotating cylinder 103 is arranged inside the fixed protective cover 104. A rotating motor 105 is arranged on the outer side of the rotating cylinder 103, and the rotating motor 105 is installed on the outer side of the fixed protective cover 104.

[0045] The fixed rod body 101 includes a fixed vertical rod 1011 and a fixed inclined rod 1012. The fixed inclined rod 1012 is integrally installed at the bottom of the fixed vertical rod 1011. A slider slides in the chute on the outer wall of the fixed plate 1 on the outer side of the fixed vertical rod 1011, and a toothed block is arranged on the outer side of the fixed vertical rod 1011 and is connected to the driving component 102. The driving component 102 includes a driving motor 1021, a driving gear 1022, and a mounting seat 1023. A mounting seat 1023 is arranged on the outer side of the driving motor 1021 and is fixed to the outer side of the fixed plate 1. A driving gear 1022 is coaxially connected to the top of the driving motor 1021, and the driving gear 1022 meshes with the toothed block on the outer side of the fixed vertical rod 1011.

[0046] The inside of the rotating cylinder 103 is a hollow structure, and mesh holes are equiangularly distributed on its outer wall. Rotating brushes 1031 are also equiangularly distributed on the outer wall of the rotating cylinder 103. The inside of the rotating cylinder 103 communicates with the collecting component 11. Protruding blocks 1041 are equiangularly distributed on the inner side of the fixed protective cover 104, and the protruding blocks 1041 and the rotating brushes 1031 are arranged alternately.

[0047] Specifically, when the robotic arm in the external environment drives the fixed plate 1 to move, the entire cleaning assembly 10 will move accordingly. First, the drive motor 1021 needs to be started to drive the drive gear 1022 at its top to rotate. When it rotates, it will mesh with the tooth block on the fixed vertical rod 1011, causing the fixed vertical rod 1011 to descend, driving the fixed inclined rod 1012 to descend. As a result, the fixed inclined rod 1012 drives the fixed protective cover 104 at its bottom and the rotating cylinder 103 inside it to descend. When the rotating brush 1031 on the outside of the rotating cylinder 103 comes into contact with the surface of the workpiece, the rotating motor 105 is started to drive the rotating cylinder 103 to rotate, and then the rotating brush 1031 rotates to clean the surface of the workpiece. When the rotating brush 1031 rotates, it will be engaged with the protruding block 1041 inside the fixed protective cover 104 in an alternating manner. Thus, under the action of the protruding block 1041, the rotating brush 1031 will be cleaned. With the setting of the external collection assembly 11, the impurities will be sucked and recovered.

[0048] Furthermore, according to Figure 2 As shown, during the suction collection, the collection assembly 11 includes a fixed box body 111, a suction pump 112, a collection drawer 113, and a suction pipe 114. A detachable and installable collection drawer 113 is arranged inside the fixed box body 111, and a suction pump 112 is installed outside the fixed box body 111. A suction pipe 114 is arranged on the outside of the suction pump 112, and the top of the suction pipe 114 penetrates through the top inside of the fixed inclined rod 1012 and penetrates into the inside of the rotating cylinder 103.

[0049] Specifically, the suction pump 112 needs to be started so that the suction pipe 114 at its top sucks the inside of the rotating cylinder 103. Since the surface of the rotating cylinder 103 is provided with a mesh structure, impurities such as impurities or oil stains will reach the inside of the suction pipe 114 through the mesh on the surface of the rotating cylinder 103. Finally, they will reach the inside of the collection drawer 113 inside the fixed box body 111 for collection. Finally, when cleaning is required, only the collection drawer 113 needs to be pulled out inside the fixed box body 111 for cleaning.
