Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon fiber prepreg processing technology, and in particular to a marking and positioning device for carbon fiber prepreg processing. Background Technology
[0002] Carbon fiber prepreg is a composite material made by bonding epoxy resin to carbon fibers using high pressure and high temperature technology. It is made of carbon fiber yarn, epoxy resin, release paper and other materials, and is processed through coating, hot pressing, cooling, lamination and winding. It is called carbon fiber prepreg or carbon fiber prepreg cloth. It is called prepreg cloth because this is only the initial impregnation of resin and carbon fiber. The final impregnation is when the product is formed.
[0003] Carbon fiber prepreg can be cut and spliced according to design requirements to better adapt to the shape and size requirements of structural components. During the cutting and splicing process, a special marking and positioning device must be used to ensure accuracy and product quality. However, when using the existing marking and positioning device, due to the long size of the carbon fiber prepreg, it is not possible to fully tension and lay the carbon fiber prepreg flat. Wrinkles or vibrations will affect the marking accuracy. In addition, there is no full recording function in the marking process. When the marking needs to be adjusted, the carbon fiber prepreg needs to be unfolded again and searched step by step, which is time-consuming and laborious. Utility Model Content
[0004] The purpose of this invention is to provide a marking and positioning device for processing carbon fiber prepreg, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a marking and positioning device for processing carbon fiber prepreg, comprising a platform, two end plates fixedly connected to both ends of the platform, a rotating shaft rotatably connected between the two opposing end plates, a drive motor mounted on the side wall of one of the end plates, anti-static brushes fixedly embedded on both sides of the top of the platform, a roll of carbon fiber prepreg wound around the outer wall of one of the rotating shafts, a transmission belt on the top of the platform, a first connecting block and a second connecting block fixedly connected to the two side walls of the transmission belt in sequence, an arc-shaped clip fixedly connected to the side wall of the second connecting block, and a marking pen engaged with the inner wall of the arc-shaped clip;
[0006] An adjustment seat is provided on one side of the middle part of the platform. A slider is slidably connected to the inner wall of the adjustment seat. A strip plate is fixedly connected to the front of the slider. Transmission cylinders are rotatably connected to both sides of the top of the strip plate. A transmission belt is sleeved between the two transmission cylinders. A motor is installed on one side of the bottom end of the strip plate. A short plate is fixedly connected to the side wall of the first connecting block. A supplementary light is installed in the middle of the short plate. A camera is snapped to one end of the short plate. A scale is fixedly connected to the front of the strip plate.
[0007] As a preferred embodiment of this utility model, the output end of the drive motor is connected to one end of one of the rotating shafts, and a rubber ring is embedded at the rotational connection between the end plate and the rotating shaft.
[0008] The above technical solution uses a drive motor to drive one of the shafts, which in turn pulls and winds up the prepreg of carbon fiber, causing the prepreg roll to be continuously rolled out. The rubber ring increases the rotational friction of the shaft, making it less likely to rotate without the drive motor. Thus, when the drive motor is not working, both shafts can remain stable and not rotate.
[0009] As a preferred embodiment of this utility model, grooves are provided in the middle of both ends of the platform, and arc-shaped protrusions are fixedly provided on the inner wall of the grooves.
[0010] The above technical solution allows for the conveying of carbon fiber prepreg by adhering to the curved surface protrusions, avoiding damage from scratches and sharp corners.
[0011] As a preferred embodiment of this utility model, a pressure plate is slidably connected to one side inner wall of the adjusting seat, and a locking screw is threadedly connected to one side wall of the adjusting seat.
[0012] By using the above technical solution, rotating the locking screw can push or pull it out, thereby causing the pressure plate to clamp or loosen the slider.
[0013] As a preferred embodiment of this utility model, one end of the locking screw is fitted with one side wall of the pressure plate, and the other side wall of the pressure plate is fitted with the side wall of the slider.
[0014] Through the above technical solution, the pressure plate is pushed by the locking screw, which can press against the slider, clamp the slider, and limit its position.
[0015] As a preferred embodiment of this utility model, the output end of the motor is fixedly connected to one of the transmission cylinders through the strip plate.
[0016] Through the above technical solution, the motor drives one of the transmission cylinders to rotate, and the transmission belt drives the other transmission cylinder to rotate accordingly.
[0017] As a preferred embodiment of this utility model, a base is fixedly connected to the middle of the outer wall of the platform, and the adjustment seat is fixedly disposed on the top of the base.
[0018] The above technical solution fixes the position of the adjustment seat, which can be used to adjust the height of the strip plate and the distance from the carbon fiber prepreg.
[0019] As a preferred technical solution of this utility model, an operation panel is installed on the outer wall of the platform. The operation panel is equipped with a drive motor switch, a motor switch and a fill light switch. The drive motor, motor and fill light are all electrically connected to an external power supply through the drive motor switch, motor switch and fill light switch respectively.
[0020] The above technical solutions are integrated into a single control panel, facilitating centralized control.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. This utility model, through the setting of a central platform and end plates on both sides, and the rotating shaft between the end plates, can slowly pull out the carbon fiber prepreg roll. While pulling it out, it flattens and passes through the upper surface of the platform, which can flatten and unfold the carbon fiber prepreg on the flat platform. This allows the carbon fiber prepreg to be fully unfolded and kept flat during the line drawing operation, avoiding the situation where the line drawing is crooked or shaking, resulting in unclear lines. This is conducive to subsequent precise cutting. The pulling and unfolding process can be made more stable by adjusting the drive motor and the rubber ring at the rotating shaft. The limit can also be fixed at any time during the unfolding and conveying process to facilitate complex line drawing operations. Two anti-static brushes embedded in the front and back of the platform surface can perform anti-static brushing operations on the surface of the carbon fiber prepreg before and after line drawing to avoid the adverse effects of static electricity before and after line drawing.
[0023] 2. This utility model, by setting a first connecting block and a second connecting block fixed on the surface of the transmission belt, allows for the adjustment of the positions of the drawing pen, camera, and supplementary light. The drawing pen, in conjunction with a ruler, can be adjusted to a precise drawing position. Simultaneously, the camera can completely record the drawing process. When subsequent line adjustments are needed, the video information can be viewed first to determine the position of the line to be adjusted, so that the adjustment position can be quickly determined later. The supplementary light on one side of the camera can be randomly controlled by the operator to clearly illuminate a part of the carbon fiber prepreg. This allows for the recording of local parts of the carbon fiber prepreg to randomly inspect the finished product quality of different parts of the carbon fiber prepreg. A quality inspection process can be carried out before the next step after drawing, namely the cutting and processing operation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1 to 5 This utility model provides a technical solution for a marking and positioning device for processing carbon fiber prepreg: Example 1:
[0032] according to Figure 1 and Figure 3 , Figure 4 As shown, a marking and positioning device for processing carbon fiber prepreg includes a platform 1. Two end plates 2 are fixedly connected to both ends of the platform 1. A rotating shaft 3 is rotatably connected between the two opposite end plates 2. A drive motor is installed on the side wall of one of the end plates 2. Antistatic brushes 5 are fixedly embedded on both sides of the top of the platform 1. A carbon fiber prepreg roll 23 is wound around the outer wall of one of the rotating shafts 3. A transmission belt 9 is provided on the top of the platform 1. A first connecting block 12 and a second connecting block 14 are fixedly connected to the two side walls of the transmission belt 9 in sequence. An arc-shaped clip 22 is fixedly connected to the side wall of the second connecting block 14. A marking pen 15 is engaged with the inner wall of the arc-shaped clip 22.
[0033] The output end of the drive motor is connected to one end of one of the rotating shafts 3. A rubber ring is embedded at the rotational connection between the end plate 2 and the rotating shaft 3. The rubber ring increases the friction at the connection, so that when the drive motor does not drive the rotation, the rotating shaft 3 does not rotate and is in a relatively stable state, so as to achieve a relatively fixed limiting function. The middle of both ends of the platform 1 is provided with a groove, and the inner wall of the groove is fixed with an arc-shaped protrusion 4. A pressure plate 20 is slidably connected to one side inner wall of the adjusting seat 7. A locking screw 21 is threadedly connected to one side wall of the adjusting seat 7. One end of the locking screw 21 is in contact with one side wall of the pressure plate 20, and the other side wall of the pressure plate 20 is in contact with the side wall of the slider 19.
[0034] In practical use, the carbon fiber prepreg processing marking and positioning device of this utility model allows the operator to place the carbon fiber prepreg roll 23 on one of the rotating shafts 3, pull out one end of the carbon fiber prepreg and lay it on the platform 1, while simultaneously winding the other end onto the other rotating shaft 3. Turning on the drive motor causes the other rotating shaft 3 to rotate, thereby continuously pulling out the carbon fiber prepreg roll 23 placed on the rotating shaft 3. As it is pulled out, it is flattened and passes through the upper surface of the platform 1. At this time, a marking pen 15 can be used to mark lines on the flattened carbon fiber prepreg. While the carbon fiber prepreg is conveyed along the surface of the platform 1, it also rubs against two antistatic brushes 5 embedded in the platform 1, performing antistatic brushing operations before and after marking lines to avoid the influence of static electricity during and after the marking process. Example 2:
[0035] Based on Example 1, such as Figure 1 and Figure 2 , Figure 5 As shown, an adjustment seat 7 is provided on one side of the middle of platform 1. A slider 19 is slidably connected to the inner wall of the adjustment seat 7. A strip plate 8 is fixedly connected to the front of the slider 19. Transmission cylinders 10 are rotatably connected to both sides of the top of the strip plate 8. A transmission belt 9 is sleeved between the two transmission cylinders 10. A motor 11 is installed on one side of the bottom of the strip plate 8. A short plate 17 is fixedly connected to the side wall of the first connecting block 12. A supplementary light 18 is installed in the middle of the short plate 17. The supplementary light 18 enhances the illumination to clearly show whether there are uneven dyeing, protrusions, damage, etc. on the surface of the carbon fiber prepreg. One end of the platform 7 is connected to a camera 13. A scale 16 is fixedly connected to the front of the strip plate 8. The output end of the motor 11 passes through the strip plate 8 and is fixedly connected to one of the transmission cylinders 10. A base 6 is fixedly connected to the middle of the outer wall of the platform 1. An adjustment seat 7 is fixedly set on the top of the base 6. An operation panel 24 is installed on the outer wall of the platform 1. The operation panel 24 is equipped with a drive motor switch, a motor switch and a fill light switch. The drive motor, motor 11 and fill light 18 are electrically connected to an external power supply through the drive motor switch, motor switch and fill light switch respectively.
[0036] In practical use, this utility model's carbon fiber prepreg processing marking and positioning device, when performing the marking operation, requires the marking pen 15 to change position. The operator can first adjust the height of the slider 19 on the inner wall of the adjusting seat 7, then rotate the locking screw 21 to push the pressure plate 20 to clamp the slider 19, thus adjusting and limiting the height of the strip plate 8. Then, by operating the control panel 24, the motor 11 is activated. The motor 11 drives the two transmission cylinders 10 to rotate, and the transmission belt 9 rotates accordingly. The first connecting block 12 and the second connecting block 14 fixed on the transmission belt 9 change position, thereby adjusting the height of the second... Connecting block 14 drives the adjustment of the position of the drawing pen 15, while the first connecting block 12 drives the adjustment of the position of the supplementary light 18 and the camera 13. The camera 13 can be used to record the entire drawing process. During the process, the supplementary light 18 can be turned on randomly to clearly illuminate the local part of the carbon fiber prepreg. At this time, the local part of the carbon fiber prepreg can be photographed and recorded to randomly inspect the finished product quality of different parts of the carbon fiber prepreg, such as whether the surface is flat, whether there is damage, whether the color is uniform, etc. This allows for a quality inspection process before the next processing operation after drawing the line.
