[0002] Composite prepreg tape patches have become key materials in high-end manufacturing fields such as aerospace, new energy wind power, automobiles, rail transit, and marine engineering due to their high strength, lightweight, corrosion resistance, and customizability, and have an irreplaceable role in structural repair, performance enhancement, and lightweight design. However, the current industry is generally facing a production process bottleneck: the preparation of composite prepreg tape patches still relies on manual cutting or simple tooling, and the production module and downstream laying process are mutually disjointed, requiring a discrete process of independent production-transportation-laying. This traditional mode has four core pain points: 1) complex processes result in low production efficiency; 2) insufficient material utilization causes significant waste; 3) quality is difficult to stabilize control (raw edges, rolled edges, dimensional accuracy, etc.); 4) the beat of the automatic production line is seriously mismatched, which becomes a key bottleneck restricting the improvement of production capacity.

[0003] In view of the above problems, it is urgent to develop a prepreg tape patch making device, and the device should have three core features: 1) flexible preparation capability to meet the needs of multiple varieties; 2) high system compatibility (including mechanical interface and process adaptation); 3) easy to seamlessly integrate into the automatic production line control system. The breakthrough of such a device will achieve three values: significantly improve product consistency, promote the upgrading of the whole production process automation, and optimize the comprehensive efficiency of the production line, ultimately achieve the industrialization goal of "quality improvement-cost reduction-efficiency increase". Its application not only has important technical innovation significance, but also can create considerable economic benefits, and has strategic value for promoting the upgrading of the composite material industry.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] It is to be understood that the terms so far as the word "comprise" and / or "comprising", or "include" and / or "including" when used in this specification is / are used to express the inclusion of one or more steps, operations, elements, and / or components, but these articles do not exclude the other steps, operations, elements, and / or components.

[0041] The relative arrangement of parts and steps, numerical expressions, and numerical values set forth in the examples are not intended to limit the scope of the application unless specifically so stated. It is also to be understood that the dimensions of the various parts shown in the drawings are not drawn to scale for ease of illustration. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the specification as appropriate. In all examples shown and discussed herein, any specific values are to be interpreted as illustrative only and not as a limitation. Thus, other examples of the exemplary embodiments can have different values. It is to be noted that like numbers and letters refer to like elements throughout the several views of the drawings and, as such, no further discussion with regard thereto is deemed necessary.

[0042] In the description of the present application, it is to be understood that the orientation or positional relationships indicated by orientation words such as "front, back, upper, lower, left, right", "transverse, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Without the opposite indication, these orientation words do not indicate and imply that the devices or elements referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application: the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component.

[0043] For purposes of the description hereinafter, spatial relative terms, such as "above", "below", "top", "bottom", "upper", "lower", and the like, can be used to describe the relative position of one element or feature to another element or feature as illustrated in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "below" other elements or features would then be oriented "below" or "above" the other elements or features. Thus, the exemplary term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatial relative descriptors used herein interpreted accordingly.

[0044] In addition, it should be pointed out that the use of the words "first", "second" and the like to describe various components is merely intended to differentiate one component from another, and does not imply a special order or sequence of the components, unless otherwise stated. Therefore, these words should not be interpreted as limiting the scope of the present application.

[0045] Referring to Figures 1-5 The present application provides a technical solution: a composite material prepreg tape conveying and patch preparation device, comprising a prepreg tape unwinding mechanism, a tension adjusting roller set, a backing paper winding mechanism, a prepreg tape conveying mechanism, a prepreg tape pre-pressing mechanism, a prepreg tape pre-heating mechanism, and a prepreg tape cutting and trimming mechanism. The prepreg tape unwinding mechanism and the backing paper winding mechanism are installed on the magnetic powder support 4 in an up-down manner. The prepreg tape conveying mechanism comprises a support surrounding plate and a tape conveying mechanism installed on the support surrounding plate. The tension adjusting roller set, the prepreg tape pre-pressing mechanism, the prepreg tape pre-heating mechanism, and the prepreg tape cutting and trimming mechanism are installed on the support surrounding plate from front to back. The coiled prepreg tape is placed on the prepreg tape unwinding mechanism, the tension adjusting roller set is used to apply tension, the backing paper winding mechanism is used to separate the prepreg tape from the backing paper and wind the backing paper onto the film winding roller 7, the separated prepreg tape is conveyed by the prepreg tape conveying mechanism, and then passes through the prepreg tape pre-pressing mechanism, the prepreg tape pre-heating mechanism, and the prepreg tape cutting and trimming mechanism in sequence, and finally a high-quality composite material prepreg tape patch with consistent size and shape is prepared.

[0046] As Figure 1 , Figure 6 , Figure 7As shown, the pre-impregnated tape unwinding mechanism includes a magnetic powder brake 1, a magnetic powder fixing plate 2, a bearing seat 3, a bearing and a tile type air inflation shaft 5. The magnetic powder brake 1 is fastened and connected with the magnetic powder fixing plate 2 through bolts, connected with the air inflation shaft 5 through the bearing seat 3, and internally connected with a key. The power transmission is matched with the key groove in the air inflation shaft 5 through the key on the brake shaft of the magnetic powder brake 1. The bearing seat 3 is located between the magnetic powder fixing plate 2 and the air inflation shaft 5, and is fixed and connected on the magnetic powder support 4 through bolts. The air inflation shaft 5 is rotatably connected on the magnetic powder support 4 through the bearing. In the initial state, the tile type air inflation shaft 5 is inflated to make the pre-impregnated tape fixed on the air inflation shaft 5 under the action of the inflation force. In the use state, the air inflation shaft 5 rotates with the movement of the pre-impregnated tape. When stopping is needed, the brake is realized through the magnetic powder brake 1.

[0047] After the pre-impregnated tape is sent from the pre-impregnated tape unwinding mechanism, it passes through a group of tension adjusting roller groups, such as Figure 1 As shown, the tension adjusting roller group includes a first tension guide roller 9, a second tension guide roller 10 and a third tension guide roller 11, which are all fixed on the pre-impregnated tape conveying mechanism front side support plate 12 through bolts. The three tension guide rollers are placed in the same vertical plane from top to bottom. After the pre-impregnated tape comes out of the pre-impregnated tape unwinding mechanism, it passes through the first tension guide roller 9 counterclockwise, then moves vertically downward to the second tension guide roller 10, and passes through the backing paper winding mechanism. Under the action of the backing paper winding mechanism, the pre-impregnated tape is separated from the surface backing paper. The backing paper is wound on the film winding roller 7 through the action of the backing paper winding mechanism, realizing the recycling of the backing paper. The pre-impregnated tape passes through the third tension guide roller 11 clockwise and enters the pre-impregnated tape conveying mechanism for transmission.

[0048] The function of the backing paper winding mechanism is to separate the pre-impregnated tape from the backing paper and realize the recycling of the backing paper. As shown in Figure 1 The backing paper winding mechanism includes a torque motor 6, a torque motor seat 40, a film winding roller 7 and a roller pressing cover 8. The torque motor 6 is connected with the torque motor seat 40 through bolts. The film winding roller 7 is internally embedded with metal parts, and is fastened and connected with the torque motor 6 through thread and glue. Finally, the torque motor seat 40 is fixed and connected on the magnetic powder support 4 through bolts. The backing paper winding mechanism is located directly below the pre-impregnated tape unwinding mechanism. In order to prevent the backing paper from sliding after winding, the roller pressing cover 8 is connected through threads at the tail of the film winding roller 7. The backing paper winding mechanism is driven by the torque motor 6 to realize the automatic separation of the pre-impregnated tape from the backing paper and the recycling of the backing paper.

[0049] After the pre-impregnated tape enters the pre-impregnated tape conveying mechanism, it passes through two groups of belt conveying mechanisms in turn. As shown in Figure 1 , Figure 8 , Figure 9 , Figure 10As shown, the prepreg tape conveying mechanism includes a servo motor 16, a motor pulley 34, a transmission pulley 35, a front small pulley 32, a rear small pulley 33, a front synchronous pulley 36, a rear synchronous pulley 37, a front conveying belt 20, a rear conveying belt 27, a lateral transmission belt 26, a short shaft 38, a long shaft 39, a bearing flange 31, two front lateral support plates 12, two rear lateral support plates 28 and a fixed bottom plate 29, the two front lateral support plates 12, the two rear lateral support plates 28 and the fixed bottom plate 29 form a support enclosure, such as Figure 11 As shown, the two front lateral support plates 12 are installed in parallel on the front side of the fixed bottom plate 29, the two rear lateral support plates 28 are installed in parallel on the rear side of the fixed bottom plate 29, the servo motor 16 is installed on the front lateral support plate 12, the servo motor 16 is connected with the motor pulley 34 through a expansion sleeve to realize power transmission, the motor pulley 34 and the transmission pulley 35 are both rotationally connected on the front lateral support plate 12, the two sides of the front conveying belt 20 are connected with the motor pulley 34 and the transmission pulley 35, the motor pulley 34, the transmission pulley 35 and the front conveying belt 20 form a first group of belt transmission mechanism; the front small pulley 32 is located on the left side of the transmission pulley 35, and the two are connected through the long shaft 39, the bearing flange 31 and the expansion sleeve, the inside is connected by a key (the long shaft 39 is connected with the inside of the transmission pulley 35 by a key), and power is transmitted to the front small pulley 32, and the bearing flange 31 is fixedly connected on the front lateral support plate 12; the front small pulley 32 and the rear small pulley 33 are located on the same side, the two sides of the lateral transmission belt 26 are connected with the front small pulley 32 and the rear small pulley 33, the two small pulleys (the front small pulley 32 and the rear small pulley 33) and the lateral transmission belt 26 form a second group of belt transmission mechanism, the rear small pulley 33 is located on one side of the front synchronous pulley 36, the rear small pulley 33 and the front synchronous pulley 36 are connected through the short shaft 38, the bearing flange 31 and the expansion sleeve, and the inside also adopts key connection to realize power transmission, the short shaft 38 is connected with the inside of the front synchronous pulley 36 by a key, and the bearing flange 31 is fixedly connected on the rear lateral support plate 28 of the support enclosure; the front synchronous pulley 36 and the rear synchronous pulley 37 are both rotationally connected on the rear lateral support plate 28, the two sides of the rear conveying belt 27 are connected with the front synchronous pulley 36 and the rear synchronous pulley 37, and the last two synchronous pulleys (the front synchronous pulley 36 and the rear synchronous pulley 37) and the rear conveying belt 27 form a third group of belt transmission mechanism. The prepreg tape conveying mechanism includes three groups of belt transmission mechanisms, the prepreg tape passes through the first group of belt transmission, then passes through the prepreg tape cutting mechanism, and then enters the third group of belt transmission mechanism, the second group of belt transmission mechanism is located on the side edge and is only responsible for power transmission, and does not convey the prepreg tape. The front conveying belt 20 and the rear conveying belt 27 have anti-sticking function, wherein the surface of the front conveying belt 20 and the rear conveying belt 27 is sprayed with a self-lubricating coating to prevent the prepreg tape from sticking.

[0050] In the process of conveying the prepreg tape, the prepreg tape first passes through the prepreg tape pre-pressing mechanism,Figure 1 、 Figure 12 、 Figure 13 、 Figure 14 As shown, the prepreg prepressing mechanism includes a double cylinder 14, a cylinder adjustment pad 13, a front pressure roller 30, a rear pressure roller 17 and a pressure roller bracket 15. The double cylinders 14 are symmetrically distributed along the conveying direction of the prepreg, and a cylinder adjustment pad 13 is placed on the outside of each double cylinder 14. The cylinder adjustment pads 13 on both sides are fixed to the two front lateral support plates 12 by bolts. The piston plates of the two double cylinders 14 are connected to the pressure roller bracket 15 by bolts respectively. The front pressure roller 30 and the rear pressure roller 17 are located on the same horizontal plane and are fixedly connected to the pressure roller bracket 15 by bolts. When the double cylinder 14 is working, the piston rod moves downward, pushing the front pressure roller 30 and the rear pressure roller 17 to generate prepressure on the prepreg. Rolling bearings are placed inside the pressure rollers, which can rotate as the prepreg is conveyed, thereby finally achieving prepressing of the prepreg. The prepreg passing through the prepreg prepressing mechanism will become flatter and will not produce warping.

The controllable electric heater 19 preheats the prepreg tape by adjusting to a suitable temperature, which plays a certain softening role and further solves the problems of curling and warping.

[0052] The prepreg tape after preheating finally reaches the prepreg tape cutting and trimming mechanism, such as Figure 1 、 Figure 15 、 Figure 16 、 Figure 17 As shown, the prepreg cutting and trimming mechanism includes a cylinder 22, a cylinder bracket 21, a knife clamp 23, a cutter 24, and a knife pressing plate 25.

The knife clamp 23 is fixedly connected to the piston rod of the cylinder 22. The cutter 24 is fastened to the groove of the knife clamp 23 by lateral bolts. The knife pressing plate 25 is located in the gap between the first and third belt drive mechanisms. When the cylinder 22 is working, the piston rod moves downward rapidly, driving the cutter 24 to move downward rapidly, achieving the cutting of the prepreg and completing the preparation of the patch. In addition, the shape of the groove of the knife clamp 23 is variable, and different types of cutters 24 can be replaced to achieve the preparation of prepreg patches of different shapes.
