Description

Technical Field

[0001] The utility model relates to the field of automatic demoulding of carbon fiber, in particular to an automatic demoulding device for carbon fiber. Background Technique

[0002] In the process of manufacturing unmanned aerial vehicles (UAVs), carbon fiber is mainly used as a structural material, especially for manufacturing key components such as the outer shell, wings, tail fins, and landing gears of UAVs. The density of carbon fiber composite materials is low, about 1 / 5 of that of steel and 1 / 2 of that of aluminum. This means that using carbon fiber can significantly reduce the overall weight of the UAV, which is extremely important for increasing flight time and load capacity.

[0003] In the process of manufacturing UAV fuselage parts, when demoulding the formed carbon fiber parts, in the traditional manual demoulding method, workers usually place a scraper on the edge of the mold and then carefully lift a part of the formed carbon fiber parts to achieve demoulding of the carbon fiber parts. This operation process must be extremely slow and delicate to avoid any damage to the carbon fiber parts. However, during the demoulding process, if the force is not properly controlled, the surface fibers of the carbon fiber material may be exposed, which not only affects the appearance and aesthetics of the finished product, but also may reduce the mechanical properties of the carbon fiber parts, and may cause deformation of the carbon fiber parts when taken out, resulting in a shape inconsistent with the design and affecting the dimensional accuracy of the carbon fiber parts, thus affecting subsequent assembly.

[0004] In view of the above problems, an automatic demoulding device for carbon fiber needs to be designed. Content of the Utility Model

[0005] In order to overcome the defect that if the force is not properly controlled, the surface fibers of the carbon fiber material are exposed, which not only affects the appearance and aesthetics of the finished product, but also may reduce the mechanical properties of the carbon fiber parts, the utility model provides an automatic demoulding device for carbon fiber.

[0006] The technical solution of the utility model is: an automatic demoulding device for carbon fiber, which includes a frame, a chain plate conveyor, a fixed seat, a sliding rod, a first spring, a suction cup type robotic arm, and a fixing component. A chain plate conveyor is installed on the upper part of the frame. A plurality of fixed seats are evenly spaced and connected to the chain plate of the chain plate conveyor. A sliding rod is slidably connected to the fixed seat. A first spring is connected between the sliding rod and the fixed seat. The sliding rod is used to fix the mold. A suction cup type robotic arm is installed on the right side of the frame. A plurality of fixing components are evenly spaced on the chain plate of the chain plate conveyor. The fixing components are located in front of the fixed seats.

[0007] Further, the fixing component includes a guide rod, a second spring and a wedge block. Multiple pairs of guide rods are evenly spaced and connected to the chain plates of the chain conveyor. A wedge block is slidably connected between two guide rods in the same group, and a second spring is connected between the front side of the wedge block and each of the two guide rods.

[0008] Further, it further includes a wedge plate, which is connected to the frame and is in contact and cooperation with the wedge block.

[0009] Further, it further includes a connecting seat, which is connected to the rear side of the frame.

[0010] Further, it further includes a support frame and a rotating plate. The support frame is connected to the rear side of the frame, and the rotating plate is rotatably connected to the support frame.

[0011] Further, the chain conveyor is horizontally arranged.

[0012] The beneficial effects of the present utility model are as follows: Through the cooperation of the guide rod, the second spring, the wedge block and the suction cup type robotic arm, when the mold reaches the predetermined position, the wedge block is no longer pressed. Under the reset action of the second spring, the wedge block moves along the guide rod to the initial position, so as to fix the mold through the cooperation of the fixing seat and the wedge block. Then, the suction cup at the end of the suction cup type robotic arm contacts the surface of the carbon fiber part, the vacuum pump is turned on to generate negative pressure, the suction cup firmly adsorbs the carbon fiber part, and the suction cup type robotic arm gently lifts it to overcome the adhesion between the carbon fiber part and the mold, realizing the separation of the carbon fiber part from the mold and improving the demolding efficiency of the carbon fiber part.

[0018] The present utility model will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment: An automatic demoulding device for carbon fiber, as Figures 1 - 4 shown, comprising a frame 1, a chain conveyor 2, a fixed seat 3, a sliding rod 4, a first spring 5, a suction cup manipulator 10, a wedge plate 11, a connecting seat 12, a support frame 13, a rotating plate 14 and a fixing component. A chain conveyor 2 is installed on the upper part of the frame 1. The chain conveyor 2 is horizontally arranged. A plurality of fixed seats 3 are evenly spaced and connected to the chain of the chain conveyor 2. A groove adapted to the fixed seat 3 is provided at the bottom of the mold, and the mold can be fixed on the fixed seat 3. A sliding rod 4 is slidably connected to the fixed seat 3, and a first spring 5 is connected between the sliding rod 4 and the fixed seat 3, which plays a role of buffering and resetting. A suction cup manipulator 10 is installed on the right side of the frame 1, which is used to perform the demoulding operation of the precision-formed carbon fiber parts. A wedge plate 11 is connected to the frame 1, and the wedge plate 11 is in contact and cooperation with the wedge block 8, which is used for the fixing and releasing of the mold. A connecting seat 12 is connected to the rear side of the frame 1, which is used to install a conveyor belt. A support frame 13 is connected to the rear side of the frame 1, and a rotating plate 14 is rotatably connected to the support frame 13. A plurality of fixing components are evenly spaced on the chain of the chain conveyor 2, and the fixing components are located in front of the fixed seat 3; the fixing component includes a guide rod 6, a second spring 7 and a wedge block 8. A plurality of pairs of guide rods 6 are evenly spaced and connected to the chain of the chain conveyor 2. A wedge block 8 is slidably connected between two guide rods 6 in the same group. Second springs 7 are connected between the front side of the wedge block 8 and the two guide rods 6 respectively, ensuring that the wedge block 8 can maintain its initial position when not under pressure, and can move along the guide rod 6 when under the pressure of the mold, realizing the positioning and releasing of the mold.

[0020] When this device is needed for automatic demolding of carbon fiber parts during the manufacturing process of UAV fuselage parts, the staff first installs the conveyor belt on the connecting seat 12. After completing the installation of the conveyor belt, they then pull the rotating plate 14 to rotate along the support frame 13 until the rotating plate 14 is adjusted to an appropriate angle. After that, the rotating plate 14 is placed on the conveyor belt, and then the rotating plate 14 is released to ensure the smooth flow of the demolded mold. Then, the rotating plate 14 is fixed in place. After the rotating plate 14 is fixed, the staff places the mold above the sliding rod 4 and then pushes the mold downward. The mold moves and contacts the sliding rod 4, applying pressure to the sliding rod 4, causing the sliding rod 4 to move downward along the fixed seat 3, and the first spring 5 is compressed. At the same time, the mold moves and contacts the wedge block 8, applying pressure to the wedge block 8, causing the wedge block 8 to move forward along the guide rod 6, and the second spring 7 is compressed. When the mold reaches the predetermined position, the wedge block 8 is no longer under pressure. Under the reset action of the second spring 7, the wedge block 8 moves along the guide rod 6 to the initial position, thereby fixing the mold through the cooperation of the fixed seat 3 and the wedge block 8. At this time, the wedge part of the wedge block 8 is located above the mold and fits with the mold to press it tightly, and the distance between the flat part of the wedge block 8 and the mold is greater than the thickness of the wedge plate 11. Repeat the above operations to ensure that all molds are installed and fixed in place. Then, start the chain plate conveyor 2, and the chain plate conveyor 2 conveys the components on it to the right. When the mold is conveyed below the suction cup manipulator 10, since the suction cup manipulator 10 is preset to the standby state, waiting for a signal to trigger, the standby suction cup manipulator 10 starts after receiving the demolding instruction. The suction cup manipulator 10 moves towards the mold, accurately aligns with the position where the carbon fiber part is located. The suction cup at the end of the suction cup manipulator 10 contacts the surface of the carbon fiber part, and the vacuum pump is turned on to generate negative pressure, and the suction cup firmly adsorbs the carbon fiber part. The suction cup manipulator 10 gently lifts it, overcoming the adhesion force between the carbon fiber part and the mold, realizing the separation of the carbon fiber part from the mold. The suction cup manipulator 10 carries the carbon fiber part to the preset target position. After reaching the target position, the vacuum pump is turned off to release the adsorption force of the suction cup, and the carbon fiber part is placed smoothly. After the manipulator completes releasing the carbon fiber part, it returns to the standby position to prepare for the next demolding operation. Then, the chain plate conveyor 2 continues to drive the components on it to move downward until the wedge plate 11 extends into the gap between the wedge block 8 and the mold and contacts the wedge block 8. As the wedge block 8 moves leftward along the wedge plate 11, when the wedge block 8 moves to the inclined surface of the wedge plate 11, the wedge plate 11 applies pressure to the wedge block 8, causing the wedge block 8 to move forward along the guide rod 6 again, and the second spring 7 is compressed again. When the wedge block 8 moves out of contact with the mold, under the reset action of the first spring 5, the sliding rod 4 moves outward along the fixed seat 3. During the movement of the sliding rod 4, the sliding rod 4 pushes the demolded mold downward to separate from the fixed seat 3, and the demolded mold falls onto the rotating plate 14 under the action of gravity and slides along its surface to the conveyor belt below.Since the conveyor belt is preset to the standby state, the conveyor belt in the standby state starts, and the conveyor belt transports the mold to the next process. Subsequently, the chain plate conveyor 2 continues to drive the remaining components to move to the left. The wedge block 8 moves to the left along the wedge plate 11 until the wedge block 8 moves out of contact with the wedge plate 11. Under the reset action of the second spring 7, the wedge block 8 moves along the guide rod 6 to the initial position again, preparing for the next round of demolding operation. Repeat the above operations. When all the molded carbon fiber parts are demolded, the chain plate conveyor 2, the suction cup manipulator 10, and the conveyor belt are turned off.
