This application claims the benefit of Chinese Patent Application No. CN202310655669.3 filed on Jun. 5, 2023, in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
Embodiments of the present disclosure relate to a cable unwinding device and a cable unwinding method.
In the prior art, a twisted pair cable includes two twisted core wires. It is often necessary to crimp terminals on the two core wires of the twisted pair cable. To conveniently crimp terminals on two core wires, it is necessary to first untwist and straighten the two core wires. In the prior art, only manual methods can be used to unwind and straighten the two core wires, which leads to very low efficiency.
According to an embodiment of the present disclosure, a cable unwinding device includes a cable clamp for clamping and fixing a cable, a core ware clamp for clamping two twisted core wires of the cable, a rotating device, and a translation device. The rotating device drives the core wire clamp to rotate around the central axis of the cable. The translation device drives the core wire clamp to move in a first horizontal direction parallel to the central axis of the cable. As the rotating device drives the core wire clamp to rotate around the central axis of the cable, the translation device drives the core wire clamp to move along the first horizontal direction, such that the two twisted core wires are untwisted and straightened.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown to simplify the drawing.
A cable unwinding device according to an embodiment of the present disclosure includes: a cable clamp for clamping and fixing a cable; a core wire clamp for clamping two twisted core wires of the cable; a rotating device for driving the core wire clamp to rotate around the central axis of the cable; and a translation device for driving the core wire clamp to move in a first horizontal direction parallel to the central axis of the cable. While the rotating device drives the core wire clamp to rotate around the central axis of the cable, the translation device drives the core wire clamp to move along the first horizontal direction, such that the two twisted core wires are untwisted and straightened.
According to another embodiment, a cable untwisting method comprises the steps of: providing the above cable untwisting device; using the cable clamp to clamp and fix the cable; clamping the roots of two exposed core wires at one end of the cable with the core wire clamp; and using the rotating device to drive the core wire clamp to rotate around the central axis of the cable, while using a translation device to drive the core wire clamp to move towards the ends of the two core wires along the axial direction of the cable.
As shown in
While the rotating device 4 drives the core wire clamp 5 to rotate around the central axis of the cable 10, the translation device 3 drives the core wire clamp 5 to move in the first horizontal direction Y, so that the two twisted core wires 11 are untwisted and straightened. The rotating device 4 is installed on the translation device 3, so that the rotating device 4 can be moved along the first horizontal direction Y with the translation device 3.

The first driving device comprises a nut 35, a screw rod 31, and a first motor 30. The nut 35 is fixed to the movable seat 32. The screw rod 31 is rotatably installed on the fixed seat 21 and threaded to the nut 35. The first motor 30 is installed on the fixed seat 21, and its output shaft is connected to one end of the screw rod 31. The first motor 30 is used to drive the screw rod 31 to rotate, so as to drive the movable seat 32 to move along the guide rail 33 through the nut 35. In the illustrated embodiment, the first motor 30 can be a servo motor, which can improve control accuracy.
A pair of support seats 34 are installed on the fixed seat 21. The two ends of the screw rod 31 are respectively rotatably installed on the pair of support seats 34.
In the illustrated embodiments, the frame 2 further comprises a pair of vertical brackets 22 and a crossbeam 23. The pair of vertical brackets 22 are fixed to the fixed seat 21. The crossbeam 23 is connected between the pair of vertical brackets 22. The cable clamp 1 is fixed to the crossbeam 23.
The cable unwinding device comprises two cable clamps 1 for clamping and fixing two cables 10, respectively. The cable unwinding device includes two core wire clamps 5, which are used to respectively clamp the core wires 11 of two of the cables 10. The rotating device 4 is installed on the movable seat 32 and is suitable for driving two core wire clamps 5 to rotate simultaneously, so that the core wires 11 of the two cables 10 are simultaneously untwisted and straightened. This can improve the efficiency of cable untwisting and straightening.
The rotating device 4 includes an installation bracket 49, a first rotating shaft 47, a second rotating shaft 48, and a second driving device. The installation bracket 49 is fixed to the movable seat 32. The first shaft 47 is rotatably installed on the installation bracket 49. The second shaft 48 is rotatably installed onto the installation bracket 49. The second driving device is installed on the movable seat 32 to drive the first shaft 47 and the second shaft 48 to rotate synchronously. The first shaft 47 and the second shaft 48 are axially connected to the two core wire clamps 5, respectively, to drive the two core wire clamps 5 to rotate synchronously. The axes of the first shaft 47 and the second shaft 48 are parallel to the first horizontal direction Y. The first shaft 47 and the second shaft 48 are spaced from each other at a predetermined distance in a second horizontal direction X perpendicular to the first horizontal direction Y.
The second driving device comprises a second motor 40, a first pulley 43, a second pulley 44, a third pulley 45, a fourth pulley 46, a first transmission belt 41, and a second transmission belt 42. The second motor 40 is installed onto the movable seat 32. The first pulley 43 is fixed to the output shaft of the second motor 40. The second pulley 44 is fixed to the first shaft 47. The third pulley 45 is fixed to the first shaft 47. The fourth pulley 46 is fixed to the second shaft 48. The first transmission belt 41 is connected between the first pulley 43 and the second pulley 44. The second transmission belt 42 is connected between the third pulley 45 and the fourth pulley 46.
