Description

[0002] Carbon fiber composite tank is a kind of pressure vessel made by winding carbon fiber on the outside of metal tank. It has the advantages of high strength, light weight and good pressure bearing performance and is widely used in the aerospace field. Composite tank generally has a double-layer structure, which is a metal lining and a composite winding layer. The current mainstream winding methods of winding layers are generally divided into robot arm full-position winding and XZ plane mobile full-position winding.

[0003] The variety of spacecraft currently in use has led to a wide variety of tank specifications for storing propellants. Aerospace products are often produced in small batches of multiple varieties. For the full-position winding of the robotic arm, manufacturers cannot purchase separate high-cost equipment for only a few small batches of products. The high procurement cost of the robotic arm and the limited range of motion of the robotic arm cannot meet the winding of multiple tank specifications, which to a certain extent restricts the development of carbon fiber composite tanks. In order to reduce the impact of equipment procurement costs and winding specifications, there is an existing XZ plane mobile full-position winding method, which winds the tank by moving in the XZ plane. Although it meets the cost and winding requirements of multiple tank specifications, the winding fiber cannot fit the tank and the wound layer tightly during the winding process, which leads to uneven fiber laying, bubbles inside the layer, resulting in poor quality, and the overall mechanical properties of the tank are not excellent enough.

[0026] Reference Figure 1 and Figure 2 The present embodiment provides a carbon fiber winding device for a storage tank, including a box body 1, the box body 1 is used to place the entire device, a clamping mechanism is arranged on one side of the box body 1, the clamping mechanism is used to clamp the storage tank 7 to be wound with carbon fiber, in the present embodiment, the clamping mechanism adopts a first flange 6, one end of the first flange 6 is detachably connected to the second flange on the storage tank 7 through a pin, and the other end of the first flange 6 is connected to a rotating drive mechanism, and the rotating drive mechanism drives the first flange 6 to rotate, thereby driving the storage tank 7 to rotate.

[0027] In this embodiment, the rotary drive mechanism includes a drive motor 12, the output end of the drive motor 12 is connected to the driving wheel 11, the driving wheel 11 is connected to the driven wheel 14 through a belt 16, and the driven wheel 14 is connected to the first flange 6 through a transmission shaft 15. The driving wheel 11 and the driven wheel 14 are arranged up and down, and the belt 16 is used for transmission in the middle, so that the occupied volume of the rotary drive mechanism can be greatly reduced, and the center of gravity of the entire device can be lowered to improve stability.

[0028] In some other embodiments, the rotary drive mechanism may also use a drive motor to directly drive the first flange to rotate via a reducer, thereby reducing costs to the greatest extent.

[0029] In this embodiment, the clamping mechanism clamps one side of the tank 7, and the other side of the tank 7 is supported by the supporting mechanism. In this embodiment, the supporting mechanism includes a second lifting mechanism, which uses a hydraulic rod 9. One end of the hydraulic rod 9 is fixed to the tank body 1, and the other end is provided with an arc-shaped air nozzle lap bracket 8. The air nozzle lap bracket 8 contacts the air nozzle of the tank. When winding carbon fiber for tanks of different specifications, the height of the second lifting mechanism can be adjusted to adapt to air nozzles at different positions.

[0030] In some other embodiments, the side of the air nozzle lap bracket 8 that contacts the air nozzle is provided with rubber or silicone, so that during the rotation of the storage tank 7, the friction between the air nozzle and the air nozzle lap bracket 8 can be reduced to the greatest extent, thereby protecting the air nozzle.

[0031] In some other embodiments, one end of the hydraulic rod 9 is fixed on the slider 10, and the slider 10 is arranged in the slide groove 17 of the box body 1. A plurality of positioning holes (not shown in the figure) are opened in the slide groove 17. The slider 10 is fixed in the slide groove 17 by the positioning pins and the positioning holes. Such a design can adjust the distance between the hydraulic rod 9 and the clamping mechanism to adapt to tanks of different sizes.

[0032] In some other embodiments, the second lifting mechanism uses a cylinder or a motor to drive the screw nut to achieve the lifting of the support mechanism.

[0033] In this embodiment, the carbon fiber winding device further includes a winding mechanism 5, which is arranged above the storage tank 7 and is used to wind the carbon fiber filaments on the surface of the storage tank 7. The winding mechanism 5 is connected to the first lifting mechanism 13, and the first lifting mechanism 13 is connected to the moving track through the translation mechanism 18; the first lifting mechanism 13 drives the winding mechanism 5 to move in the vertical direction, so as to adjust the distance between the winding mechanism 5 and the storage tank 7 below, so that during the process of winding the carbon fiber, the carbon fiber can be closely attached to the surface of the storage tank 7, so that the fiber is laid evenly, no bubbles are generated inside the layer, and the mechanical properties of the storage tank are improved.

[0034] In this embodiment, the carbon fiber winding device also includes a movable track, which is arranged above the winding mechanism 5 and fixed on the movable track bracket 2, and the movable track bracket 2 is fixed on the box body 1. The movable track is used to set up the first lifting mechanism 13 and guide it; specifically, the movable track includes two parallel straight tracks 3, and the two sides of the two straight tracks 3 are connected by an arc-shaped turning track 4. The edge side of the turning track 4 is tilted downward, and the projection of the entire movable track on the horizontal plane is elliptical. Since the middle part of most storage boxes 7 is cylindrical and the two sides are hemispherical, it is impossible to adjust the angle between the carbon fiber spinneret 52 in the winding mechanism 5 and the surface of the storage box by only adjusting the height of the winding device 5 through the first lifting mechanism 13, especially the hemispherical areas on both sides. If the two are not perpendicular, bubbles are likely to appear during the winding process, resulting in an unsatisfactory winding effect. Therefore, the entire moving track is divided into two parts, two straight tracks 3 and an arc-shaped turning track 4, and the edge side of the turning track 4 is tilted downward to adapt to the hemispherical area of ​​the storage box 7. In this way, the angle between the carbon fiber spinneret 52 and the surface of the storage box can be adjusted, bubbles in the winding process can be reduced, and the winding quality can be improved.

[0035] In some other embodiments, the straight track 3 and the turning track 4 are detachably connected via a connector, so that when winding tanks of different sizes, the length of the straight track 3 can be adjusted, thereby changing the length of the moving track.

[0036] Reference Figure 3 In this embodiment, the winding mechanism 5 includes a frame 51, which is connected to the first lifting mechanism 13. A carbon fiber spinneret 52 is arranged in the frame 51. The carbon fiber spinneret 52 is connected to an eccentric wheel 53. The eccentric wheel 53 is connected to a stepper motor 54. The eccentric wheel 53 is driven to rotate by the rotation of the stepper motor 54, thereby adjusting the angle between the outlet of the carbon fiber spinneret 52 and the horizontal plane.

[0037] It should be noted that since the storage box 7 is not a standard part, the storage box 7 and the translation track cannot be perfectly matched. Therefore, when the winding mechanism 5 is on the turning track 4, the nozzle of the carbon fiber spinneret 52 and the surface of the storage box 7 cannot be completely perpendicular. Therefore, it is necessary to adjust the angle of the carbon fiber spinneret 52 to make the two perpendicular. By rotating the eccentric wheel 53 by the stepper motor 54, the angle between the outlet of the carbon fiber spinneret 52 and the horizontal plane can be fine-tuned. Especially for the concave area, the angle between the carbon fiber spinneret and the surface of the storage box 7 can be adjusted to the greatest extent, so that the carbon fiber filaments and the storage box 7 fit perfectly.

[0038] In addition, a distance detector is provided in the winding mechanism 5, and the distance detector is used to detect the distance between the wire outlet of the winding mechanism 5 and the surface of the storage box 7, and the distance detector is electrically connected to the controller. In this embodiment, the distance detector 5 adopts an infrared sensor. It should be noted that although this embodiment adopts an infrared sensor, the protection scope of the present invention is not limited thereto, and other distance detectors such as ultrasonic sensors, laser sensors, optical sensors, etc. are all within the protection scope of the present invention.

[0039] During the movement of the winding mechanism 5, the distance between the carbon fiber spinneret 52 and the surface of the lower storage box 7 can be detected by the distance detector, and the size of the entire storage box 7 can be determined according to the detected distance. During the overshoot of winding, the distance between the outlet of the carbon fiber spinneret 52 and the storage box 7 can be adjusted by the first lifting mechanism 13, and the eccentric wheel 53 can be driven to rotate by the stepping motor 54, so as to adjust the angle between the outlet of the carbon fiber spinneret 52 and the horizontal plane. When the preset distance and angle are reached, the spinning and winding starts, which can ensure that the carbon fiber filaments are closely fitted to the storage box to the greatest extent, and there are no bubbles inside the layer, thereby improving the mechanical properties of the storage box.

[0040] In this embodiment, the first lifting mechanism 13 includes a base 131, which is fixedly connected to the translation mechanism 18. A first lifting motor 132 is connected to the base 131. The output shaft of the first lifting motor 132 is connected to a screw 133. A nut is connected to the screw 133. The nut is connected to the winding mechanism 5. The screw 133 is driven to rotate by the rotation of the first lifting motor 132, and the up and down movement of the winding mechanism 5 is completed by the cooperation between the screw 133 and the nut.

[0041] In some other embodiments, the first lifting mechanism 13 adopts a cylinder or a hydraulic rod.

[0042] In this embodiment, the translation mechanism 18 includes a roller, and a hub motor is provided on the roller. The hub motor drives the roller to rotate, thereby driving the winding mechanism 5 to move on the moving track.

[0043] In some other embodiments, the translation mechanism 18 includes a driving wheel, a traction motor, and a guide wheel. The driving wheel and the guide wheel can be assembled in a straight track and a turning track. The traction motor can move the winding device along the straight track and the turning track to complete the winding process.

[0044] In some other embodiments, the present invention further provides a carbon fiber winding method for a tank, using the carbon fiber winding device described in any of the above embodiments, comprising the following steps: Step 1: Fix the storage box 7 to be wound with carbon fiber to the clamping mechanism, adjust the position of the supporting mechanism, and set up the storage box.

[0045] Step 2: The storage box 7 is driven to rotate by the rotary drive mechanism, and the first lifting mechanism is driven by the translation mechanism 18 to drive the winding mechanism 5 to move on the moving track; while moving, the distance detection device is used to detect the distance between the outlet of the carbon fiber spinneret 52 and the storage box 7 below to be wound with carbon fiber in real time, and the data is transmitted to the controller.

[0046] Step 3, the controller determines the surface structure of the storage box 7 through the distance data, and determines the distance that the first lifting mechanism needs to lift at each position and the angle that the eccentric wheel 53 needs to rotate during the entire winding process according to the preset distance between the wire outlet and the storage box 7 during the winding process.

[0047] Step 4: restore the winding mechanism 5 and the rotary drive mechanism to their initial positions.

[0048] Step 5, the rotary drive mechanism rotates to drive the storage box 7 to rotate, and at the same time the translation mechanism drives the first lifting mechanism and then drives the winding mechanism 5 to move on the moving track. During the movement, the distance between the wire outlet and the storage box 7 is adjusted by the first lifting mechanism, and the angle between the wire outlet and the storage box is adjusted by the eccentric wheel 53. When the distance and the angle reach the preset value, the carbon fiber spinneret 52 spins.

[0049] Step 6: Repeat step 5 until the carbon fiber winding of the entire storage tank 7 is completed.

[0050] The carbon fiber winding device recorded in this embodiment clamps the storage box and rotates it through a clamping mechanism, and uses a translation mechanism 18 to drive the winding mechanism 5 to move on the moving track. The distance between the outlet of the winding mechanism 5 and the surface of the storage box 7 is detected by a distance detector, and the distance between the carbon fiber spinneret 52 and the storage box 7 is adjusted by a first lifting mechanism. At the same time, the eccentric wheel 53 is used to adjust the angle between the outlet of the carbon fiber spinneret 52 and the horizontal plane. In this way, it can ensure that the carbon fiber filaments are closely fitted to the storage box to the greatest extent, there are no bubbles inside the layer, and the mechanical properties of the storage box are improved.
