Description

[Detailed description of the invention] [Purpose of the invention] Regarding.

In order to clarify the classification (product type, system type, current capacity, etc.), a straight line 1, spiral line 2, chain line 3, etc. of different colors are combined with the basic color, as shown in Figure 3 (a) to (c). These electric wires 4, 4', 4' were processed to complete a wire harness 5 as shown in FIG. 4.

Therefore, when manufacturing the various electric wires with terminals 61, 62, 65, which are harness elements shown in Fig. 5, it is necessary to manufacture many types of electric wires with different colors, wire diameters, etc. Then, in the process of manufacturing wire harnesses, electric wires with terminals are manufactured using automatic wire processing equipment that combines measuring, cutting, stripping, terminal attachment, housing insertion, etc. of each electric wire one by one. The idea was to tie them together according to their circuits and create sub-harnesses or main harnesses.

``Let's do it'', fortune-telling According to the above conventional technology, the following problems remain.

(1) For example, 300 to 400 different colored electric wires must be manufactured and managed for each automobile.

(2) For wires of the same type, the automatic processing equipment will store the information such as stripping the insulation coating, the presence or absence of terminals, and the type of terminals in advance in the control unit. However, when changing to a different type of wire, The work software must be changed each time, which increases the storage capacity load on the control device.

(3) When the electric wire with a terminal is automatically inserted into the housing at the final stage of the automatic processing device, the work becomes even more complicated.

This invention was made to solve the above-mentioned problems, and its purpose is to greatly reduce the types of electric wires used in the manufacture of wire harnesses, and to reduce the load on the control section of the above-mentioned electric wire processing equipment. Another object of the present invention is to provide a method for manufacturing an electric wire with a terminal and an apparatus therefor, which allow easy modification of work software.

[Structure of the invention]

The present invention is directed to each harness element (
In other words, designations such as letters and figures, which are the information necessary for attaching a terminal, are printed on both ends of a bare wire or electric wire that has not yet been crimped with a terminal, and based on this printed information, the wire is The type, application, and subsequent processing steps are determined.

According to the present invention, using long bare (electrical) wires of the same type,
By changing the specifications to be printed on both ends,
It is now possible to manufacture many types of electric wires with terminals by arbitrarily specifying and changing the type of terminal to be crimped, the stripping position required for terminal crimping, the housing insertion of the terminal part, etc., and all the problems of the conventional method have been solved. resolved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to drawings showing embodiments.

The electric wires with terminals shown in Figures 1 (A) to (C) have data printed on both ends of each strand 10+, 402, and 103, which are harness elements, indicating the type of wire, purpose, work (processing) procedure, etc. ×1 + X25 XI, X4 and X5
．． Xs, and further different types of terminals 11, 12 and 13 were crimped based on these data.

These printing can be performed by any method such as a method of ejecting ink using an ultrasonic vibrator, a normal pressure printing method, or an angry pressure printing method. In the figure, (a) shows a wire 101 with barcodes attached to several locations on the outer periphery (XI, X2), and (b) shows a combination of similar barcodes and numbers (X2,
Xa) and (c) are the same dot marks (Xs, X6). Any combination of figures, numbers, etc. to be printed is possible, but for example, barcodes (XI,
X2-) is convenient for indicating the working procedure of the wire, which will be described later, and the numbers are convenient for indicating the designation of the housing and the insertion hole when inserting the &iiJ element into the housing by hand.

FIG. 2 is a plan view showing an embodiment of the device of the present invention.

The device 20 for automatic wire terminals is constructed by installing various devices A to G described below on a common workbench 21, and one side edge along the length of the workbench 21 is provided with a pair of clamps. A wire gripping and conveying device 23 having a gripping tool 22 and movable over time is provided.

Reference numeral A denotes a supply/cutting device for electric wire W, which is composed of a wire straightening/feeding roll 24, a measuring/feeding roll 25, a cutting blade 26, etc., and a printing device G is installed above the cutting blade 26 so as to be able to rise and fall freely. . The printing device G includes two print heads 27 located on both front and rear sides of the cutting blade 26 so as to sandwich the cutting blade 26 therebetween.

B is a wire stripping device that determines the crimp position of the terminal, that is, the necessary stripping length, and performs the stripping; C, D, and E are terminal crimping devices each equipped with different terminals; F is an automatic terminal housing insertion device It is.

The devices A to D are each equipped with sensors a to d for reading data printed on electric wires.
E is provided with terminals and reading sensors e and f for housing insertion.

Further, each of the devices A to G is connected to a control device (not shown), and operates in response to commands from information read by the sensors a to f.

Next, the operation of the apparatus shown in FIG. 2 will be explained.

First, based on another information command stored in the control device, the electric wire straightening/feeding roll 24 and measuring/feeding roll 2 are activated.
5 is activated, a predetermined length of the electric wire is measured, the electric wire is fed in, and the electric wire is fixed by the measuring/feeding roll 25 and the gripper 22.

Next, the printing device G descends, and the specified items such as the type of electric wire, its purpose, and the work procedure are printed on X1 to X1 shown in Figure 1 (A) to (C).
After printing as shown in X6, it returns to the predetermined position.

Printing is simultaneously performed at 21 tli positions on both sides of the cutting blade 26 by two print heads 27.

The printed characters, figures, etc. are read by the sensor a in the wire supply device A, and in response to the command, the cutting blade 26 is activated to cut the wire W. After that, the wire gripping and conveying device is activated to cut the wire. The wire W1 is moved to the next wire stripping device B. At the same time, the next electric wire W is sent to the supply device A by a predetermined length. If the print is not printed or is unclear, the sensor a cannot obtain the necessary information and the cutting blade 26 does not operate.

The wires conveyed facing the wire stripping device B determine the type of terminal to be crimped from the printed information read by the sensor b, and after stripping the terminal to the necessary crimp position, that is, a predetermined length. , and transported to the terminal crimping device C.

In the terminal crimping device C, the sensor C similarly reads the printed information and determines whether or not to crimp the terminal provided in the crimping device C to the transported electric wire W1. If the terminal crimping device does not work, the next terminal crimping device or E
are transported sequentially.

That is, the terminal crimping device C is attached to the electric wire W based on the printed information.
-E, a predetermined terminal is crimped.

The last terminal crimping device E is equipped with a sensor f, which determines whether the terminal crimped to the electric wire should be automatically inserted into the housing and the position of the insertion hole. Yes
When s, the next housing automatic insertion device F operates, and the terminal is inserted and locked in the predetermined insertion hole of the predetermined housing 28, and when NO, the insertion device F does not operate and the terminal is inserted. The wire W+ that has been removed is transported to the next process as it is, and is
is opened and released. Note that the electric wire left after cutting in the supply cutting device A is folded back into a loop shape in the next feeding process as necessary, and the folded end is held in the gripping tool 22.
By holding the wire in place, you can attach terminals to both ends of the wire.

In this way, the steps of cutting the wire, stripping the wire, crimping the terminal, and inserting the wire into the housing are performed based on information such as characters and graphics printed on the end of the wire.

The length of the wire to be measured and cut by the wire supply/cutting device A, and the information such as characters and figures printed by the printing device G can be set in any combination by programming the control device in advance. Therefore, a wide variety of electric wires with terminals having different lengths, terminals, etc. can be manufactured from one type of electric wire.

〔Effect of the invention〕

Since the present invention is as explained above, it has the following effects.

(11) The manufacturing composition of the electric wires required for the wire harness can be limited to a small number of types (color, type of insulator, purpose, etc.).
