Cable processing device

This application claims the benefit of Chinese Patent Application No. CN202121791620.3 filed on Aug. 3, 2021, the whole disclosure of which is incorporated herein by reference.

The present disclosure relates a cable processing device.

Before connecting a cable with two core wires wound together, the outer sheath at the end of the cable needs to be removed to expose the two core wires. After removing the sheath, it is necessary to straighten the exposed two core wires. Finally, the two straightened core wires are separated by a predetermined spacing. In this way, the subsequent connection operation of the core wires can be facilitated.

However, in the prior art, there is no cable processing equipment capable of performing the above operations, so the above processing operations need to be performed manually, and the processing efficiency of the core wires is very low.

A cable processing device comprises a cable clamping device for clamping a cable to be processed. The device further includes a core wire straightening device for straightening a pair of exposed core wires of the fixed cable, and a core wire separating device for separating the straightened pair of core wires by a predetermined spacing.

Referring generally to FIGS. 1 - 5 , the cable processing device includes a cable clamping device 10 , a core wire straightening device 20 and a core wire separating device 30 . The cable clamping device 10 is used to clamp and fix the cable 1 . The core wire straightening device 20 is used to straighten the exposed two core wires 1 a of the fixed cable 1 (see FIG. 7 a ). The core wire separating device 30 is used to separate the two core wires 1 a that have been straightened by a predetermined spacing (see FIG. 9 a ). The cable processing device further includes a frame 100 . The cable clamping device 10 , the core wire straightening device 20 and the core wire separating device 30 are installed on the frame 100 .

The cable clamping device 10 includes a gripper 11 and a driving device 12 . The gripper 11 is adapted to be opened and closed. The driving device 12 is used to drive the gripper 11 to open or close. When the gripper 11 is closed, the cable 1 is clamped on the gripper 11 so that the cable 1 is fixed. The gripper 11 includes a fixed block 11 a and a movable block 11 b . The fixed block 11 a is fixed to the frame 100 of the cable processing device. The movable block 11 b can be moved between an open position and a closed position with respect to the fixed block 11 a . The driving device 12 includes, but is not limited to, a cylinder mounted on the frame 100 and connected to the movable block 11 b to drive the movable block 11 b to move between the open position and the closed position.

FIG. 7 shows a schematic diagram of straightening the core wire 1 a by using the core wire straightening device 20 shown in FIG. 4 . FIG. 7 a shows a schematic diagram after the core wires 1 a of the cable 1 are straightened. As shown in FIGS. 1 - 2 , 4 , 7 and 7 a , the core wire straightening device 20 includes a mounting frame 201 , a clamp 21 , a first driving device 22 and a second driving device 23 . The mounting frame 201 is movably mounted on the frame 100 of the cable processing device and can be moved along the axis Y of the cable 1 . The clamp 21 is mounted on the mounting frame 201 and is suitable to be opened and closed, and is used to clamp two core wires 1 a . The first driving device 22 is mounted on the mounting frame 201 to drive the clamp 21 to open or close. The second driving device 23 is mounted on the frame 100 to drive the mounting frame 201 and the clamp 21 mounted thereon to move along the axial direction Y.

When the clamp 21 is closed, there is a gap between the clamp and the two core wires 1 a to allow the clamp 21 to move in the axial direction Y of the cable 1 with respect to the two core wires 1 a . In this way, it is possible to prevent abrasion of the two core wires 1 a when the clamp 21 moves along the axial Y direction of the cable 1 . After the clamp 21 is clamped on the roots or bases of the two core wires 1 a , the second driving device 23 drives the clamp 21 to move to the ends of the two core wires 1 a along the axial direction Y to straighten the two core wires 1 a.

The clamp 21 includes a fixed clamping block 21 a and a movable clamping block 21 b . The fixed clamping block 21 a is fixed to the mounting frame 201 . The movable clamping block 21 b is movably mounted on the mounting frame 201 and can be moved between the open position and the closed position with respect to the fixed clamping block 21 a . The first driving device 22 includes a first cylinder connected to the movable clamping block 21 b for driving the movable clamping block 21 b to move between the open position and the closed position.

The second driving device 23 includes a second cylinder connected to the mounting frame 201 to drive the mounting frame 201 and the clamp 21 to move in the axial Y direction along the cable 1 with respect to the two core wires 1 a.

FIG. 9 shows a schematic diagram of separating two core wires 1 a by a predetermined spacing using the core wire separating device 30 shown in FIG. 8 . FIG. 9 a shows a schematic diagram in which the two core wires 1 a of the cable 1 are separated by a predetermined spacing. Referring now to FIGS. 1 - 2 , 5 - 6 , 8 , 9 and 9 a , the core wire separating device 30 includes two support frames 301 , two clamping devices 31 , two first drive mechanisms 32 and a second drive mechanism 33 and 34 . The two support frames 301 are movably mounted on the frame 100 of the cable processing device and can be moved in the first direction X perpendicular to the axis Y of the cable 1 .

The two clamping devices 31 are respectively installed on the two support frames 301 , which are suitable to be opened and closed, and are used to respectively clamp the two core wires 1 a that have been straightened. The two first drive mechanisms 32 are respectively installed on the two support frames 301 to drive the two clamping devices 31 to open or close. The second drive mechanism 33 and 34 is installed on the frame 100 to drive the two support frames 301 to move away from or close to each other so that the two clamping devices 31 are moved away from or close to each other. After the two clamping devices 31 respectively clamp the two core wires 1 a , the second driving mechanism 33 and 34 drives the two clamping devices 31 to move away from each other so that the two core wires 1 a are separated by a predetermined spacing in the first direction X. The core wire separating device 30 also includes a slide rail 302 . The slide rail 302 is mounted on the frame 100 and extends in the first direction X.

The second driving mechanism 33 and 34 includes a driving plate 34 and a linear driving device 33 . A pair of slots 34 a are formed on the driving plate 34 . The linear driving device 33 is connected to the driving plate 34 for driving the driving plate 34 to move along the axis Y of the cable. The support frame 301 has legs 301 a , and the legs 301 a of the two support frames 301 are slidably assembled in the pair of slots 34 a respectively. When the linear driving device 33 drives the driving plate 34 to move along the axial Y of the cable, the driving plate 34 drives the two support frames 301 to move away from or close to each other in the first direction X through the pair of slots 34 a . The linear driving device 33 includes a servo motor 33 a and a transmission mechanism 33 b . The servo motor 33 a is mounted on the frame 100 .
