Abstract
An electrical cable manufacturing method includes: in a joining device including a first facing surface and a second facing surface facing each other in a first direction, and a pressing member and a vibrating member facing each other in a second direction, setting an interval between the first facing surface and the second facing surface to a first distance; placing core wires between the first facing surface and the second facing surface having the interval set at the first distance; and joining the core wires by ultrasonic vibration. The core wires include core wires having different outer diameters. The first distance is larger than a maximum value between values of outer diameters of the core wires and smaller than the sum of the maximum value and a minimum value.
Claims3
An electrical cable manufacturing method comprising:
- setting an interval between a first facing surface and a second facing surface in a first direction to a first distance, in a joining device including the first facing surface and the second facing surface facing each other in the first direction, and a pressing member and a vibrating member facing each other in a second direction orthogonal to the first direction;
- placing a plurality of core wires between the first facing surface and the second facing surface having the interval set at the first distance;
- and
- joining the core wires by using the vibrating member to apply ultrasonic vibration to the core wires while sandwiching the core wires between the pressing member and the vibrating member, wherein
- the core wires include core wires having outer diameters having mutually different values, and
- the first distance is larger than a maximum value between values of outer diameters of the core wires and smaller than a sum of the maximum value and a minimum value between the values of the outer diameters of the core wires.
An electrical cable manufacturing apparatus comprising:
- a first facing surface and a second facing surface facing each other in a first direction;
- a pressing member and a vibrating member facing each other in a second direction orthogonal to the first direction;
- a controller configured to acquire a first distance corresponding to outer diameters of a plurality of core wires to be joined;
- and
- a driving mechanism configured to vary an interval between the first facing surface and the second facing surface in the first direction, wherein
- the first distance is larger than a maximum value between values of the outer diameters of the core wires and smaller than a sum of the maximum value and a minimum value between the values of the outer diameters of the core wires,
- the electrical cable manufacturing apparatus is configured to
- receive the core wires in a gap between the first facing surface and the second facing surface with the interval set at the first distance, and
- join the core wires by ultrasonic vibration applied to the core wires by the vibrating member while sandwiching the core wires between the pressing member and the vibrating member.
