Description

[0001] DESCRIPTION [0002] Harness cable manufacturing apparatus [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness cable manufacturing apparatus, and more particularly, to a harness cable manufacturing apparatus that improves the harness cable production yield by automating the process of cutting off, cutting, and connecting a pin connector to a cable.

Generally, a harness cable is a cable that connects a power source or an electrical signal between a vehicle or an electric device provided in various electric or electronic devices.

At this time, the harness cable is classified into small, medium and large according to the use purpose.

For example, medium- and large-size harness cables are mainly used for automobiles, ships, aircraft, military equipment or large ships, and small harness cables are used for small electronic devices such as mobile phones, notebooks and digital cameras.

The harness cable is connected at one end with a connector pin, which is connected to another terminal inside the electronic device, and an electric wire exposed to the outside at the other end is soldered to a board or a board to connect an electrical signal and a signal between the electric devices do.

Patent Document 1 is related to a cable cutting device, and Patent Document 2 is related to a cable breaking device, and FIG. 1 is a view showing a pin connector compression device.

Here, the cable cutting device and the cable breaking device refer to Patent Documents 1 and 2, and the pin connector press device will be described with reference to Fig.

First, with reference to Patent Document 1, when the cable is extended to the workpiece guide and the workpiece supply unit, the up-down cylinder and the LM unit of the workpiece supply unit are operated, and when the cable is moved by a predetermined pitch, The block advances in the Y-axis direction and pushes the cable toward the fixed clamping block, so that the cable is clamped between the clamping blocks.

At this time, two cylinders are operated simultaneously to interlock the press blocks, and the cutter blade in each press block enters from both sides of the cable to cut the cable.

A plurality of materials (cables) thus obtained are respectively subjected to a peeling operation through an optical fiber stripping stripper of Patent Document 2.

With reference to Patent Document 2, by placing the slider close to the fixed end, the cutout portion is opened with a distance by the elasticity of the movable member.

Then, when the operator presses the movable portion, the cable sheath is cut while the cut-out portion is in contact with the cable sheath in a state in which the cable sheath is raised on the first cutout groove and the position to be deviated from the end portion of the cable is measured and fitted using a ruler. Pulling the cable will cause the cable to peel off.

By repeating the above process by the operator repeatedly, the cable sheath is removed, thereby obtaining a plurality of cables from which a single sheath has been stripped.

Thereafter, the connector pin is pressed onto the cable through the compression device shown in Fig.

1, a work table 10, a receiving portion 20 installed on the upper surface of the work table 10 to support a cable C and a connector pin P so as to support the receiving portion 20, A pushing portion 30 provided on the upper surface of the work table 10 for lifting and lowering the connector pin P to press the connector pin P on the peeled portion of the cable C, And a guide 40 for guiding the light.

The receiving portion 20 is a structure having a recessed structure formed by an upper light blocking structure.

The pressing portion 30 is configured to engage with the receiving portion 20.

Here, the peeled portion of the cable C is placed on the receiving portion 20, and the pin connector P is stacked on the peeled portion of the cable C in this state.

Then, the pressing portion 30 is operated to move up and down so that the pressing portion 30 is engaged with the receiving portion 20.

Then, the pushing portion 30 enters the recessed portion 20, and presses the pin connector P and the cable C at the same time.

At this time, both ends of the pin connector P are pressed by inclined surfaces formed by the depression of the receiving portion 20, and are folded in directions opposite to each other, thereby wrapping the peeled portion of the cable C.

Thus, the harness cable to which the pin connector is connected at one end is manufactured through the process described above.

However, when the harness cable is manufactured using the above-described devices and mechanisms

First, it is troublesome for the operator to collect the cable cut by the cell unit, and the collected cable must be moved to the place where the apparatus and the device corresponding to the next process are located. There is a problem that the number of unnecessary working personnel is increased due to mobilization of personnel.

Secondly, since a large number of bulky equipments are provided, the number of personnel is increased by attaching personnel to each of the equipments, and the number of working people is increased, There is a problem.

Third, the process of removing and compressing the outer skin is manually performed by the operator, resulting in an increase in the defective product rate, a difficulty in producing a uniform product, a reduction in the production yield due to a change in product manufacturing time according to the efficiency of the worker, There is a problem that the reliability is lowered.
