Technical Field
[0001] This invention relates to a robotic arm, and more particularly to a guided robotic arm. Background Technology
[0002] Existing carbon fiber guided robotic arms employ a circumferential winding method. This method allows the carbon fiber to be wound onto a substrate through a cross-winding technique, achieving rapid and uniform fiber layer stacking. However, the circumferential winding method has some limitations when handling complex curved surfaces or irregularly shaped products. It cannot fully adapt to the shapes of non-circular surfaces, and the winding precision is not high enough, resulting in irregular winding patterns. Summary of the Invention

Carbon fiber is wound onto the carbon fiber winding device, which is adapted to rotate about its own axis. Each carbon fiber winding device corresponds to one of the traction devices.
[0005] The traction device is positioned close to the carbon fiber winding device. The traction device hooks onto the end of the carbon fiber to be wound. When the carbon fiber winding device rotates around its own axis, the traction device moves left and right relative to the frame along the axis of the carbon fiber winding device.
[0006] The clamping device includes a clamping element and a roller. The clamping element is used to clamp the end of the carbon fiber to be wound and move the carbon fiber to be wound to a position close to the surface of the carbon fiber winding device. The roller is used to press the carbon fiber to be wound against the carbon fiber winding device. The clamping element and the roller are adapted to move in the front-back, left-right, and up-down directions.
[0007] The cutting device includes scissors adapted to move back and forth, the scissors being used to cut the carbon fiber.

The first support is connected to the frame. The clamping element and the roller are both disposed on the clamping element telescopic mechanism. The clamping element telescopic mechanism is disposed on the clamping element forward and backward movement mechanism. The clamping element forward and backward movement mechanism is disposed on the clamping element up and down movement mechanism. The clamping element up and down movement mechanism is disposed on the first support. The clamping element up and down movement mechanism is adapted to move up and down relative to the first support.
[0010] The present invention guides a robotic arm, wherein the clamping element is a wire cutter.
[0011] This invention guides a robotic arm, wherein the cutting device further includes a guide rail, a transmission chain, a motor, a scissor frame, and a second support. The second support is connected to the frame, and the guide rail is disposed on the second support. The direction of the guide rail is parallel to the axial direction of the carbon fiber winding device. The scissors are disposed on the scissor frame and are adapted to move relative to the guide rail. The scissor frame is connected to the transmission chain, and the motor drives the transmission chain to move, thereby causing the scissor frame to move relative to the guide rail.
[0012] The present invention guides a robotic arm, wherein a guide column is provided on the frame, and the clamping device and the shearing device are both connected to the guide column, and the position of the guide column on the frame is adjustable.

[0016] This invention discloses a guided robotic arm, comprising a frame, a carbon fiber winding device mounted on the frame, a traction device, a clamping device, and a cutting device. The carbon fiber winding device is adapted to rotate around its own axis.

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the present invention provides a guided robotic arm, comprising a frame 1, a carbon fiber winding device 2 mounted on the frame 1, a traction device 3, a clamping device 4, and a cutting device 5. The guided robotic arm is used to wind carbon fiber or other thread-like materials onto the carbon fiber winding device 2. In this embodiment, winding carbon fiber is used as an example. The carbon fiber winding device 2 is adapted to rotate around its own axis. One or more carbon fiber winding devices 2 and traction devices 3 are provided, with a one-to-one correspondence between the carbon fiber winding device 2 and the traction device 3.
[0027] The traction device 3 is positioned close to the carbon fiber winding device 2. The traction device 3 is used to hook the end of the carbon fiber to be wound. When the carbon fiber winding device 2 rotates around its own axis, the traction device 3 is adapted to move left and right relative to the frame 1 along the axis of the carbon fiber winding device 2. During this process, the carbon fiber is wound onto the carbon fiber winding device 2.
[0028] The clamping device 4 includes a clamping element 41 and a roller 42. The clamping element 41 is used to clamp the end of the carbon fiber to be wound and move the carbon fiber to be wound to a position close to the surface of the carbon fiber winding device 2. The roller 42 is used to press the carbon fiber to be wound against the carbon fiber winding device 2. The clamping element 41 and the roller 42 are adapted to move in the front-back, left-right, and up-down directions to move the carbon fiber to be wound to a position close to the surface of the carbon fiber winding device 2 when winding begins, and to return to their original positions after winding is completed.
[0029] The cutting device 5 includes scissors 51, which are adapted to move back and forth. The scissors 51 are used to cut carbon fibers. When it is necessary to cut carbon fibers, the cutting device 5 moves forward and then moves backward after cutting.
[0030] In this invention, when a robotic arm is working, the clamping element 41 clamps one end of the carbon fiber to be wound and moves it to a position close to the surface of the carbon fiber winding device 2, so that the roller 42 is tangent to the carbon fiber winding device 2, clamping the carbon fiber to be wound between the roller 42 and the carbon fiber winding device 2. After the traction device 3 pulls the one end of the carbon fiber to be wound, the clamping element 41 and the roller 42 are released. The carbon fiber winding device 2 first rotates half a turn in the opposite direction to wind the carbon fiber onto the carbon fiber winding device 2. Then, the traction device 3 swings back and forth, and the carbon fiber winding device 2 rotates in the forward direction to wind the carbon fiber. After the carbon fiber winding is completed, the cutting device 5 moves forward to cut the carbon fiber, the clamping element 41 moves to the initial position, and the robotic arm's work of guiding the carbon fiber is completed. This invention provides a guided robotic arm, comprising a frame 1, a carbon fiber winding device 2 mounted on the frame 1, a traction device 3, a clamping device 4, and a cutting device 5. The carbon fiber winding device 2 is adapted to rotate around its own axis. When the carbon fiber winding device 2 rotates around its own axis, the traction device 3 is adapted to move left and right relative to the frame 1 along the axis of the carbon fiber winding device 2, winding the carbon fiber onto the carbon fiber winding device 2, thereby improving the accuracy and efficiency of carbon fiber winding. Furthermore, the shape and structure of the carbon fiber winding device 2 have no impact on the winding process. Meanwhile, since the clamping device 4 includes a clamping element 41 and a roller 42, the clamping element 41 can clamp one end of the carbon fiber to be wound, making the roller 42 tangential to the carbon fiber winding device 2, clamping the carbon fiber to be wound between the roller 42 and the carbon fiber winding device 2. And the traction device 3 can pull one end of the carbon fiber to be wound, starting the winding from the end of the carbon fiber. Therefore, it can solve the problem of the difficulty in winding the end of the carbon fiber, reduce the labor intensity of the operator, and ensure the operator's production safety.
[0031] Optionally, the carbon fiber traction device 3 includes a mounting frame 31 and a fixing hook 32. The fixing hook 32 is connected to the mounting frame 31, which is connected to the frame 1. The mounting frame 31 is adapted to move left and right relative to the frame 1 along the axial direction of the carbon fiber winding device 2. The fixing hook 32 is used to hook the end of the carbon fiber to be wound, which can solve the problem of the difficulty in winding the end of the carbon fiber.
[0032] Optionally, the clamping device 4 further includes a clamping element telescopic mechanism 43, a clamping element forward and backward moving mechanism 44, a clamping element up and down moving mechanism 45, and a first bracket 46. The first bracket 46 is connected to the frame 1. The clamping element 41 and the roller 42 are disposed on the clamping element telescopic mechanism 43. The clamping element telescopic mechanism 43 is disposed on the clamping element forward and backward moving mechanism 44. The clamping element forward and backward moving mechanism 44 is disposed on the clamping element up and down moving mechanism 45. The clamping element up and down moving mechanism 45 is disposed on the first bracket 46. The clamping element up and down moving mechanism 45 is adapted to move up and down relative to the first bracket 46. Specifically, the first bracket 46 is provided with a guide rail. A motor drives the clamping element up and down moving mechanism 45 to move up and down on the guide roller. A cylinder drives the clamping element forward and backward moving mechanism 44 to move back and forth on the clamping element up and down moving mechanism 45. The clamping element telescopic mechanism 43 can be a cylinder mechanism or a lead screw mechanism. The clamping device 4 also includes a clamping element telescopic mechanism 43, a clamping element forward and backward movement mechanism 44, and a clamping element up and down movement mechanism 45, so that the positions of the clamping element 41 and the roller 42 can be adjusted as needed in three mutually perpendicular directions, making it more convenient to use.
[0033] Optionally, the clamping element 41 is a wire cutter that clamps the carbon fiber when closed.
[0034] Optionally, the cutting device 5 further includes a guide rail 52, a transmission chain 53, a motor 54, a scissor frame 55, and a second support 56.

The scissor frame 55 is connected to the transmission chain 53, and the motor 54 drives the transmission chain 53 to move, thereby causing the scissors frame 55 to move relative to the guide rail 52. The scissors 51 being mounted on the scissor frame 55 and adapted to move relative to the guide rail 52 allows for more accurate adjustment of the scissors 51's position.
[0035] Optionally, such as Figure 2 , Figure 3 As shown, a guide column 13 is also provided on the frame 1. The clamping device 4 and the shearing device 5 are both connected to the guide column 13. A column guide rail is provided on the frame 1, and the guide column 13 is set on the column guide rail. The servo motor drives the guide column 13 to move on the column guide rail via the track 14 to adjust the position of the guide column 13 on the frame 1, thereby adjusting the position of the clamping device 4 and the shearing device 5 on the frame 1 to adapt to different models of carbon fiber winding devices 2, making the guided robotic arm of the present invention more widely applicable. After the position is adjusted, the guide column 13 is fixed to the frame 1 by the support column, making the guided robotic arm of the present invention more convenient to use.
