Description

Technical Field

[0001] This invention relates to the field of cable processing, and more particularly to a cable wrapping mechanism for aerospace applications. Background Technology

[0002] In existing technologies, conductive tape needs to be wrapped around the surface of cables during processing. This tape-wrapping process is usually done manually or by machine. While manual tape wrapping can ensure accuracy, it is inefficient, especially when dealing with thicker cables, as manual operation is inconvenient. Existing machine operations typically involve clamping the cable, attaching the tape, and then rotating it. The machine then moves the tape holder, and the cable's rotation pulls the tape on the holder. Although this method is efficient, the tape output from the tape holder cannot be effectively controlled, and since the cable itself rotates to a certain extent, relying on the cable's rotation to pull the tape will result in uneven tape output. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an aerospace cable wrapping mechanism that can control the tape output to match the cable rotation and achieve uniform tape adhesion.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an aerospace cable wrapping tape mechanism, comprising a tape output mechanism, a displacement mechanism, and a cable rotation mechanism. The tape output mechanism includes a tape frame, an output motor, an output wheel, a sensing wheel, a mounting frame, a first position sensor, and a second position sensor. Tape is wound on the tape frame. The output wheel is located on one side of the tape frame and is drivenly connected to the output motor. The mounting frame is located on the side of the output wheel away from the tape frame. The mounting frame is provided with a sensing wheel that moves along the height direction of the mounting frame. The first position sensor is located near its upper side, and the second position sensor is located near its lower side. The first position sensor and the second position sensor are electrically connected to the output motor to sense the position of the tape. The displacement mechanism is connected to the tape output mechanism and drives the tape output mechanism to move along a first direction. The cable rotation mechanism is provided with a cable extending along the first direction and drives the cable to rotate.

[0005] The beneficial effects of this invention are as follows: the output motor drives the output wheel to rotate, causing the tape on the tape holder to be output towards the cable at the cable rotation mechanism. When the tape is output, one side abuts against the induction wheel. When the cable rotation mechanism drives the cable to rotate, due to the certain amplitude of the cable's rotation, the tape output may not match the cable rotation, resulting in either too little or too much tape output. When this situation is fed back to the induction wheel, if the tape output is too little, the induction wheel is raised by the tape; if the tape output is too much, the induction wheel is pressed down, and the tape is in a low position. This position change is sensed by the first and second position sensors and fed back to the output motor, which adjusts the output wheel speed to ensure that the tape output matches the cable rotation. The displacement mechanism drives the tape output mechanism to move at a constant speed along the first direction, so that the entire cable can be evenly wrapped with tape.

[0012] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0013] Please refer to Figure 1 and Figure 2A cable winding tape mechanism for aerospace applications includes a tape output mechanism 1, a displacement mechanism 2, and a cable rotation mechanism 3. The tape output mechanism 1 includes a tape holder 11, an output motor 12, an output wheel 13, a sensing wheel 14, a mounting frame 15, a first position sensor 16, and a second position sensor 17. Tape is wound on the tape holder 11. The output wheel 13 is located on one side of the tape holder 11 and is connected to the output motor 12 for transmission. The mounting frame 15 is located on the side of the output wheel 13 away from the tape holder 11. The mounting frame 15 has a [missing information - likely a cable rotation mechanism] along the [missing information - likely a cable rotation mechanism]. The system includes a sensing wheel 14 that moves in the height direction; a first position sensor 16 is provided near the upper side of the mounting bracket 15; a second position sensor 17 is provided near the lower side of the mounting bracket 15; the first position sensor 16 and the second position sensor 17 are electrically connected to the output motor 12 to sense the position of the tape; the displacement mechanism 2 is connected to the tape output mechanism 1, and the displacement mechanism 2 drives the tape output mechanism 1 to move along the first direction; the cable rotation mechanism 3 is provided with a cable extending along the first direction, and the cable rotation mechanism 3 drives the cable to rotate.

[0014] As can be seen from the above description, the beneficial effects of the present invention are as follows: the output motor 12 drives the output wheel 13 to rotate, so that the tape on the tape holder 11 is output towards the cable at the cable rotation mechanism 3, and one side of the tape abuts against the induction wheel 14 when it is output; when the cable rotation mechanism 3 drives the cable to rotate, since the cable itself rotates with a certain amplitude, the tape output at a uniform speed will result in the tape output not matching the cable rotation, resulting in the tape output being too little or too much. When this situation is fed back to the induction wheel 14, it means that the tape output is too little, the induction wheel 14 is raised by the tape, and the tape output is too much, the induction wheel 14 presses the tape down to a low position. The change in this position is sensed by the first position sensor 16 and the second position sensor 17 and fed back to the output motor 12, so that it adjusts the speed of the output wheel 13 to ensure that the tape output matches the cable rotation; the displacement mechanism 2 drives the tape output mechanism 1 to move at a uniform speed along the first direction so that the entire cable can be evenly wrapped with tape.

[0015] Furthermore, the tape output mechanism 1 also includes a first mounting base 18 and a second mounting base 19; the first mounting base 18 is connected to the displacement mechanism 2; the second mounting base 19 is provided with a tape frame 11, an output wheel 13 and a mounting frame 15 in sequence along its length direction, and the second mounting base 19 is rotatably mounted on the first mounting base 18.

[0016] As described above, the first mounting base 18 is connected to the displacement mechanism 2, thereby enabling the entire tape output mechanism 1 to move; the rotational cooperation between the second mounting base 19 and the first mounting base 18 allows the operator to easily adjust the output tape to wrap tape at different angles on the cable as needed.

[0017] Furthermore, the second mounting base 19 is provided with a placement plate 20 with an anti-stick coating at the position corresponding to the sensing wheel 14.

[0018] As described above, when the tape wrapping operation stops, the tape that has already been applied can adhere to the placement plate 20, preventing it from sticking to other components and affecting the preparation for the next operation.

[0019] Furthermore, the displacement mechanism 2 includes a displacement seat 21, a displacement motor 22, and a moving belt 23. The displacement seat 21 is provided with a displacement port 211 along its first direction. The moving belt 23 is provided in the displacement port 211 and is connected to the displacement motor 22 in a transmission manner. The tape output mechanism 1 is movably disposed in the displacement port 211 and connected to the moving belt 23.

[0020] As can be seen from the above description, the displacement port 211 on the displacement seat 21 serves as the moving path of the tape output mechanism 1, and the displacement motor 22 drives the moving belt 23 to rotate, thereby driving the tape output mechanism 1 to move.

[0021] Furthermore, the cable rotating mechanism 3 includes a rotating component and a clamping component. The clamping component includes two jaws 31 and corresponding jaw mounting brackets 32. The line connecting the two jaw mounting brackets 32 is parallel to the first direction. Each of the two jaw mounting brackets 32 is rotatably provided with jaws 31. The two jaws 31 are respectively used to clamp the two ends of the cable. The rotating component drives the jaws 31 to rotate.

[0022] As described above, the clamp mounting bracket 32 ​​can place the cable at a certain height to avoid interference with other components when its rotation range is large; the clamps 31 clamp both ends of the cable, and the rotating component drives the clamps 31 to rotate, thereby causing the cable to rotate.

[0023] Furthermore, the rotating assembly includes a rotating motor 33, a rotating shaft 34, a rotating shaft mounting base 35, a rotating belt 36, a first rotating wheel 37, and a second rotating wheel 38. Multiple rotating shaft mounting bases 35 are arranged sequentially along a first direction. The rotating shaft 34 is rotatably mounted within the rotating shaft mounting base 35. One end of the rotating shaft 34 is connected to the rotating motor 33. The rotating shaft 34 has two first rotating wheels 37 corresponding to two gripper mounting frames 32. The gripper mounting frames 32 have second rotating wheels 38 connected to the grippers 31. The rotating belt 36 is connected to both the first rotating wheel 37 and the second rotating wheel 38.

[0024] As described above, by setting the rotating belt 36, the rotation position of the cable can be far away from the rotating shaft 34, thereby avoiding interference of the cable rotation with other components; the rotating motor 33 drives the rotating shaft 34 to rotate, causing the first rotating wheel 37 on the rotating shaft 34 to rotate; under the transmission action of the rotating belt 36, the second rotating wheel 38 is driven to rotate, thereby realizing the rotation of the gripper 31.

[0025] Furthermore, the clamping assembly also includes two guide rails 39, which are arranged along a first direction and correspond one-to-one with the gripper mounting bracket 32; the gripper mounting bracket 32 ​​moves in cooperation with the guide rails 39.

[0026] As described above, the guide rail 39 allows the operator to adjust the distance between the gripper mounting brackets 32 to accommodate cables of different lengths.

[0027] Furthermore, the gripper 31 is a pneumatic gripper 31.

[0028] As can be seen from the above description, using pneumatic grippers 31 to clamp the cable ensures reliable clamping while also facilitating implementation.

[0029] Furthermore, the tape holder 11 is provided with a winding shaft 201, a top block 202 and a spring, and the tape is sleeved on the winding shaft 201; the winding shaft 201 is provided with two opposing top blocks 202 in the middle, and a spring is provided between the two top blocks 202; the two top blocks 202 respectively abut against the tape.

[0030] As described above, the tape is sleeved on the winding shaft 201, and the two top blocks 202 on the winding shaft 201 abut against the adjacent tape portion under the action of the spring, thereby fixing the sleeved tape.

[0031] Furthermore, the top block 202 has a pressing block 203 protruding from the end face of the winding shaft 201.

[0032] As can be seen from the above description, by setting the protruding pressing block 203, when it is necessary to replace the tape, simply press the protruding pressing block 203 to release the pressure of the top block 202 on the tape, making it easy to remove the used tape.

[0033] Reference Figure 1 and Figure 2 Embodiment 1 of the present invention is as follows:

[0034] The application scenario of this invention is as follows: In the traditional cable wrapping tape process, taking machine processing as an example, since the machine usually pulls the tape by rotating the cable, the tape output of the tape holder 11 cannot be effectively controlled. Moreover, the cable rotation itself has a certain range, and relying on the cable rotation to pull the tape will cause the tape output to be uneven.

[0035] like Figure 1 and Figure 2 As shown, the aerospace cable wrapping tape mechanism of this embodiment includes a controller, a tape output mechanism 1, a displacement mechanism 2, and a cable rotation mechanism 3. The controller is electrically connected to the tape output mechanism 1, the displacement mechanism 2, and the cable rotation mechanism 3.

[0036] The tape output mechanism 1 includes a tape holder 11, an output motor 12, an output wheel 13, a sensing wheel 14, a mounting bracket 15, a first position sensor 16, a second position sensor 17, a first mounting base 18, and a second mounting base 19.

[0037] The tape holder 11 is provided with a winding shaft 201, a top block 202 and a spring, and the tape is sleeved on the winding shaft 201; the winding shaft 201 is provided with two opposing top blocks 202 in the middle, and a spring is provided between the two top blocks 202; the two top blocks 202 respectively abut against the tape, and the top blocks 202 have a pressing block 203 protruding from the end face of the winding shaft 201.

[0038] The output wheel 13 is located on one side of the tape holder 11 and is connected to the output motor 12 for transmission. The mounting frame 15 is located on the side of the output wheel 13 away from the tape holder 11. The mounting frame 15 is provided with a sensing wheel 14 that moves along the height direction of the mounting frame 15. A first position sensor 16 is provided near the upper side of the mounting frame 15, and a second position sensor 17 is provided near the lower side of the mounting frame 15. The first position sensor 16 and the second position sensor 17 are electrically connected to the output motor 12 to sense the position of the tape. The first mounting base 18 is connected to the displacement mechanism 2. The second mounting base 19 is provided with the tape holder 11, the output wheel 13 and the mounting frame 15 in sequence along its length direction. The second mounting base 19 is rotatably mounted on the first mounting base 18. A placement plate 20 with an anti-stick coating is provided on the second mounting base 19 corresponding to the position of the sensing wheel 14.

[0039] The displacement mechanism 2 includes a displacement seat 21, a displacement motor 22, and a moving belt 23. The displacement seat 21 has a displacement port 211 along its first direction. The moving belt 23 is provided in the displacement port 211 and is connected to the displacement motor 22 in a transmission manner. The first mounting seat 18 is movably disposed in the displacement port 211 and is connected to the moving belt 23.

[0040] The cable rotating mechanism 3 includes a rotating component and a clamping component. The clamping component includes two guide rails 39, two grippers 31, and corresponding gripper mounting brackets 32. The line connecting the two gripper mounting brackets 32 is parallel to the first direction. Each of the two gripper mounting brackets 32 is rotatably provided with a gripper 31, which is a pneumatic gripper 31. The two grippers 31 are respectively used to clamp the two ends of the cable. The guide rails 39 are arranged along the first direction, and the guide rails 39 correspond one-to-one with the gripper mounting brackets 32. The gripper mounting brackets 32 move in coordination with the guide rails 39.

[0041] The rotating assembly includes a rotating motor 33, a rotating shaft 34, a rotating shaft mounting base 35, a rotating belt 36, a first rotating wheel 37, and a second rotating wheel 38. Multiple rotating shaft mounting bases 35 are arranged sequentially along a first direction. The rotating shaft 34 is rotatably mounted within the rotating shaft mounting base 35. One end of the rotating shaft 34 is connected to the rotating motor 33. The rotating shaft 34 has two first rotating wheels 37 corresponding to two gripper mounting frames 32. The gripper mounting frames 32 have second rotating wheels 38 connected to grippers 31. The rotating belt 36 is connected to both the first rotating wheel 37 and the second rotating wheel 38.

[0042] The working principle of this invention is as follows: Before processing, the position of the clamp mounting bracket 32 ​​on the guide rail 39 is first adjusted to match the length of the cable, and then the two ends of the cable are respectively engaged with the two clamps 31; then the tape is pulled out from the tape holder 11, passes through the output wheel 13 and the sensing wheel 14 in sequence, and is pasted to the end of the cable.

[0043] The controller then operates the displacement motor 22, the output motor 12, and the rotation motor 33. The output motor 12 drives the output wheel 13 to rotate, thereby continuously driving the tape output of the tape holder 11; the displacement motor 22 drives the moving belt 23 to rotate, thereby driving the tape output mechanism 1 to move along the first direction; the rotation motor 33 drives the rotating shaft 34 to rotate, and with the cooperation of the rotating belt 36, the first rotating wheel 37, and the second rotating wheel 38, the gripper 31 drives the cable to rotate; under the simultaneous action of the three, the tape is evenly wrapped around the cable.

[0044] Specifically, during the tape output process, when the cable rotates too fast, causing the tape output to be unable to match the cable rotation, the tape at the sensing wheel 14 will lift the sensing wheel 14, thereby causing the first position sensor 16 located on the upper side to sense it, causing the output motor 12 to speed up the rotation of the output wheel 13 and speed up the tape output; the same applies to the opposite.

[0045] In summary, the aerospace cable wrapping tape mechanism provided by this invention uses an output motor to drive an output wheel to rotate, causing the tape on the tape holder to be output towards the cable at the cable rotation mechanism. During tape output, one side of the tape abuts against the induction wheel. When the cable rotation mechanism drives the cable to rotate, due to the cable's own rotation amplitude, the tape output may mismatch the cable rotation, resulting in either too little or too much tape output. When this situation is fed back to the induction wheel, if the tape output is too little, the induction wheel is raised by the tape; if the tape output is too much, the induction wheel presses the tape down to a low position. This positional change is sensed by a first position sensor and a second position sensor and fed back to the output motor, causing it to adjust the output wheel speed to ensure that the tape output matches the cable rotation. A displacement mechanism drives the tape output mechanism to move uniformly along a first direction, ensuring that the entire cable is evenly wrapped with tape.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
