Description

Technical Field

[0001] The present application relates to the field of cable processing technology, and in particular to a device for stripping the outer sheath of the inner conductors of a multi-core wire. Background Art

[0002] With the development of miniaturization and integration of electronic devices, multi-core cables are increasingly used in various electronic devices. Multi-core cables are usually composed of multiple thin conductors, wrapped in an outer layer of insulation. During the production process, it is often necessary to strip the outer covering of multiple thin conductors to a very short length to meet the needs of specific equipment. Traditional stripping methods mainly rely on manual operation or semi-automated equipment, which is inefficient and difficult to ensure accuracy. Currently, the common multi-core cable stripping technologies on the market mainly include the following: 1. Mechanical blade cutting method: The outer covering of multiple thin wires is cut by a mechanical blade, and then the wires are stripped manually or semi-automatically. This method is simple and easy to use, but it is easy to damage the wires, and the stripping length is difficult to accurately control.

[0003] 2. Laser cutting method: Use laser beam to cut the outer skin of multiple thin wires. It has high precision, but the equipment cost is expensive and has high requirements for the operating environment.

[0004] 3. Hot melt stripping: The outer covering of multiple thin wires is softened by heating and then stripped. This method is effective for the outer covering of some materials, but it can easily cause the outer covering to remain or the internal wires to be damaged by heat.

[0031] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1 and Figure 2, is a device for stripping the outer sheath of the internal conductors of a multi-core wire disclosed in an embodiment of the present application, including a first support frame 10, a first driving mechanism 20, a cable clamping mechanism 30, a second driving mechanism 40 and a cutting mechanism 50.

[0033] Among them, the first driving mechanism 20 is arranged on the first support frame 10, the cable clamping mechanism 30 is connected to the first driving mechanism 20, the second driving mechanism 40 is arranged at the upper end of the cable clamping mechanism 30 away from the first driving mechanism 20, and the cutting mechanism 50 is arranged on the first support frame 10. The first driving mechanism 20 is used to drive the cable to rotate, and the cable clamping mechanism 30 is used to fix the multi-core cable. The second driving mechanism 40 separates the multiple wires in the multi-core cable and rotates synchronously with the first driving mechanism 20, so that the cutting mechanism 50 cuts a certain length of the outer skin of each wire in turn and peels off the outer skin from the wire.

[0034] For details, see Figure 2 and Figure 3 The first driving mechanism 20 includes a first driving assembly 21 and a first rotating assembly 22. The first driving assembly 21 includes a first driving member 211 and a driving wheel 212. The first driving member 211 is a driving motor, which runs through the first support frame 10 and is connected to the driving wheel 212. The power output shaft of the motor is connected to the driving wheel 212. The driving wheel 212 is usually a gear structure. Of course, other transmission wheel structures such as pulleys can also be used to achieve power transmission. The first rotating assembly 22 includes a meshing driven wheel 221 and a main rotating wheel 222. The driven wheels 221 are set to two, and the driving wheel 212 is meshed with the two driven wheels 221 to drive the main rotating wheel 222 to rotate. The driven wheel 221 is also a gear structure, meshing with the driving wheel 212 and the main rotating wheel 222 to form a multi-stage transmission, which can change the transmission speed and torque. The main rotating wheel 222 is provided with an opening 2221, through which the multi-core cable is clamped to the cable clamping mechanism 30. The opening 2221 extends perpendicularly through the center of the rotation of the main rotating wheel 222. This multi-stage transmission method stably transmits power from the first driving member 211 to the main rotating wheel 222, thereby driving the multi-core cable clamped by the cable clamping mechanism 30 to rotate, ensuring stable and accurate rotation.

[0035] For further information, see Figure 2 、 Figure 3 and Figure 4 The cable clamping mechanism 30 includes a first fixed component 31 and a telescopic component 32. One end of the first fixed component 31 is fixed to the first rotating component 22. The telescopic component 32 passes through the first rotating component 22 and is connected to the first fixed component 31.

[0036] Specifically, the first fixing assembly 31 includes a snap-fit fixing member 311 and a fixing rod 312. The snap-fit fixing member 311 is snapped onto the main rotating wheel 222. The snap-fit fixing member 311 is generally a flexible clamp structure that is clamped onto the main rotating wheel 222 through elastic deformation. Other fixing methods such as bolt connection can also be used, which are not limited here. The fixing rod 312 is connected to the snap-fit fixing member 311 and is located between the main rotating wheel 222 and the core abutment member 42. The fixing rod 312 is provided with a plurality of retaining members 3121 for accommodating multi-core cables. The retaining members 3121 are arc-shaped groove structures for better accommodating and fixing multi-core cables.

[0037] The telescopic assembly 32 includes a contact member 321, a stretching rod 322, and a pneumatic member 323. The contact members 321 are provided in multiple configurations and are movably connected to the multiple stop members 3121 to form a receiving groove 3211 for the multi-core cable. The contact members 321 are block-shaped and have multiple cross-sections, as shown in the figure. The stretching rod 322 extends through the main rotating wheel 222 and connects to the multiple contact members 321. The pneumatic member 323 is located at the lower end of the main rotating wheel 222, away from the core contact member 42, and is connected to one end of the stretching rod 322. The pneumatic member 323 is a cylinder. When the cylinder is in operation, it drives the stretching rod 322 to move, thereby driving the multiple contact members 321 to abut the multi-core cables fixed in the receiving groove 3211. This structural design allows the cable clamping mechanism 30 to be flexibly adjusted according to the thickness and number of cables, ensuring reliable clamping of the multi-core cables.

[0038] For further information, see Figure 2 and Figure 3 The second driving mechanism 40 includes a second driving component 41 and a wire core abutment 42. The second driving component 41 is fixed on the first support frame 10. One end of the wire core abutment 42 is connected to the second driving component 41, and the other end is used to plug into the end of the multi-core cable (people manually plug the end of the multi-core cable into the wire core abutment 42) to separate each wire in the multi-core cable.

[0039] The second drive assembly 41 rotates synchronously with the first drive assembly 21 to control the rotation of the multi-core cable. The second drive assembly 41 is a motor that precisely controls its speed and direction to achieve synchronous rotation with the first drive assembly 21. The wire abutment 42 is a fork-shaped structure, with its branches inserted into the ends of the multi-core cable to separate the individual wires and facilitate subsequent cutting. The structure and appearance of the wire abutment 42 are shown in the figure.

[0040] For further information, see Figure 2 and Figure 4The cutting mechanism 50 includes a third driving component 51, a sliding frame 52, a fourth driving component 53, a cutting component 54 and a first grating component 55. The sliding frame 52 is connected to the third driving component 51, the fourth driving component 53 and the cutting component 54 are connected to the sliding frame 52, and the first grating component 55 is arranged on the cutting component 54 for sensing the wire as the third driving component 51 moves.

[0041] The third drive assembly 51 includes a third support frame 511, a third drive member 512, a first drive connector 513, and a guide rail 514.

The fixing member 521 is mounted on the first drive connector 513, and the slide rail 522 is mounted on the guide rail 514. The third drive member 512 drives the sliding frame 52 to slide back and forth relative to the third support frame 511. The third drive member 512 is a cylinder, and the telescopic movement of the cylinder connecting rod drives the sliding frame 52 to slide along the guide rail 514.

[0042] See also Figure 4 and Figure 5 The fourth drive assembly 53 includes a fourth drive member 531 and a second drive connecting member 532. The fourth drive member 531 is fixed to the sliding frame 52. One end of the second drive connecting member 532 is connected to the fourth drive member 531, and the other end is used to abut the cutting assembly 54. The fourth drive member 531 is a cylinder, and the second drive connecting member 532 is pushed to abut the cutting assembly 54 by the extension and contraction of the cylinder connecting rod.

[0043] The cutting assembly 54 includes a cutting knife 541, a cutting knife connecting rod 542 and a limiting member 543. The cutting knife 541 includes two staggered blades. The cutting knife connecting rod 542 is provided in two to respectively connect the two staggered blades. The end of the cutting knife connecting rod 542 away from the cutting knife 541 is provided with a rolling member 5421. The rolling member 5421 is used to slide against the second driving connecting member 532. The end of the second driving connecting member 532 away from the fourth driving member 531 is provided with a conical surface. The first grating assembly 55 is fixed on the cutting knife connecting rod 542. The limiting member 543 is located between the two cutting knife connecting rods 542, and limiting grooves 5431 are provided on both side ends of the limiting member 543 for the cutting knife connecting rod 542 to pass through.

[0044] When the fourth drive member 531 drives the second drive connector 532 to move, the tapered surface cooperates with the rolling element 5421 to move the two offset blades closer or farther from each other, cutting the wire sheath. The third drive member 512 also drives the cutting blade 541 backward to remove the sheath from the wire. The first grating assembly 55 can sense the position of the wire in real time. When the presence of the wire is detected, it controls the third drive member 512 to drive the cutting blade 541 to move a certain distance toward the multi-core cable for cutting, ensuring accurate cutting length.

[0045] In addition, see Figure 2 and Figure 6 The device also includes a cable end clamping assembly 60, which is located between the telescopic assembly 32 and the wire core abutment 42. The cable end clamping assembly 60 includes a second support frame 61, a second driving member 62 and a matching clamping claw member 63.

The first sensor 71 is arranged on the first support frame 10 relative to the driving wheel 212, and the first sensing member 72 is fixed on the driving wheel 212. The first sensor 71 is used to sense the first sensing member 72 rotating with the driving wheel 212.

[0048] The first sensor 71 may be a photoelectric sensor, which senses the rotational position of the first sensing member 72 and provides feedback on the rotational state of the driving wheel 212 , so as to precisely control the first driving member 211 .

[0049] For further information, see Figure 3 The device also includes a second sensor assembly 80, which includes a second sensor 81 and a second sensing member 82. The second sensor 81 is arranged relative to the second sensing member 82 and is fixed on the first support frame 10. The second sensing member 82 is arranged between the second driving assembly 41 and the wire core abutment member 42. The second sensor 81 is used to sense the second sensing member 82 that rotates with the second driving assembly 41.

[0050] The second sensor 81 may also be a photoelectric sensor, which is used to monitor the rotation of the second drive assembly 41 and ensure the synchronization between the second drive assembly 41 and the first drive assembly 21 .

[0051] For further information, see Figure 1 The device further includes: an outer shell 90 and a second grating component 100, which is arranged at the entrance of the outer shell 90. The second grating component 100 can sense whether the multi-core cable enters the device, playing the role of safety protection and feeding detection.

[0052] In addition, the device is provided with start buttons (not marked in the figure) on both sides of the entrance of the outer shell 90. The start buttons on both sides need to be pressed at the same time to start the device, so as to avoid misoperation of the buttons on one side.

[0053] The working principle of this embodiment is as follows: Through the coordinated operation of various mechanisms, the device achieves high-precision automatic sheath stripping of multiple wires within a multi-core cable. The first drive mechanism 20 and the second drive mechanism 40 rotate synchronously, driving the multi-core cable to rotate. The cable clamping mechanism 30 and the cable end clamping assembly 60 secure the cable. The wire core abutment 42 of the second drive mechanism 40 separates the wires. The cutting mechanism 50 cuts the sheath of each wire to a certain length based on the sensing signal of the first grating assembly 55. During the cutting process, while the cutting blade 541 remains in the cutting state, it is driven by the third drive assembly 51, causing the cutting blade 541 to move away from the wire, dragging a certain length of the sheath off the wire, thereby stripping the wire sheath. The first sensor assembly 70 and the second sensor assembly 80 monitor the rotation state of the drive assembly in real time to ensure the stability and synchronization of the device. The second grating assembly 100 detects the feeding of the device and provides safety protection. Compared with the traditional multi-core wire sheath stripping method, this device improves the stripping accuracy and efficiency, reduces damage to the wires, solves the problems existing in the existing technology, and has significant practicality and innovation.
