Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supporting the manufacture of a wire harness and an instruction device for supporting a work.

[0002]

2. Description of the Related Art Generally, when manufacturing a wire harness, a plurality of electric wires are routed on a work table called a wiring board, and a connector is connected to the routed wire bundle or taping is performed. Or mounting exterior parts. The shape of the wire harness is extremely complicated, the number of attachment parts is large, and the processing steps are diverse. Therefore, techniques for displaying work procedures and the like by various methods have been conventionally proposed.

For example, Japanese Patent Application Laid-Open No. 9-147641 proposes a technique for instructing a worker on a wiring order, a component assembling position, and the like using visible light such as a laser beam. The gist is to provide a guidance device capable of irradiating visible light in the YX direction on the wiring board, and to irradiate the visible light to a wiring path, a holder of a wire harness, and the like in accordance with the order of wiring the wires on the wiring board. It is to do. Then, as is apparent from the column 0014 of the publication, a procedure of displaying a predetermined work position with visible light, ending the work at the displayed work position, and displaying the position of the next work with visible light. Is configured to be repeated.

[0004]

However, simply irradiating visible light in the order of work requires detection of the end of work for each work process of the worker, which requires a very complicated switching operation. In addition, there is a problem that a device for detecting switching is complicated.

That is, if there are, for example, N steps required to manufacture one wire harness on a wiring board, it is necessary to switch the irradiation position of visible light N times. At that time, it is necessary to detect whether or not the work is progressing for each process, and to input the progress of the work to the control unit for switching the irradiation position. Are required, and the detection method becomes complicated. For this reason, the above-described conventional configuration is not suitable for a product requiring a multi-step manufacturing operation such as a wire harness.

It is also conceivable to switch the display position by setting a timer or the like. In this case, however, it is necessary to set / change the switching time for each process.
The setting itself becomes complicated. In addition, if the switching time is set for each process, the set time tends to deviate from the actual work time of the operator, which is not preferable.

[0007] Further, in the support method for guiding work support over time, there is a case where the display mode is difficult and difficult to press the operator, and the efficiency is not necessarily improved.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a wire harness manufacturing support method and a work support instruction device capable of displaying a multi-step manufacturing procedure with a configuration as simple as possible. The challenge is to do.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a wire harness manufacturing support method for instructing the work procedure of a manufacturing process with visible light when wiring wires are wired on a wiring board to manufacture a wire harness. A method for supporting the manufacture of a wire harness, characterized in that a processing part of the wire harness related to the order and a part accommodating part are simultaneously illuminated with the visible light.

According to the present invention, the work order at each display position can be displayed by simultaneously irradiating a plurality of work positions with visible light. In this way, it is possible to display the work order without detecting the progress of the worker one by one. Here, the term “simultaneously” is not limited to the strict meaning at the same time, but may be any degree as long as a human can identify the same at the same time by the trajectory of visible light.

As a mode of irradiating the work position, it is preferable to scan and illuminate a plurality of locations with one light source.

In this case, since the work position can be displayed at the same time, there is no restriction over time, and it is easy to appropriately change the display state according to the work state of the worker.

Alternatively, the processed part of the wire harness and the corresponding part accommodating part may be displayed simultaneously as a pair using a plurality of light sources.

As a specific embodiment of the present invention, it is preferable to adopt a procedure in which a standard operation time corresponding to the operation procedure is set, and the light source illuminates a lighting location for the standard operation time.

[0015] In a more specific embodiment, it is preferable that the step of simultaneously illuminating with the visible light is to oscillate a single light source to illuminate linearly.

With this configuration, the processing portion of the wire harness and the corresponding component housing can be illuminated as a pair with only a single light source, so that the present invention can be implemented with a relatively simple lighting device. It becomes possible.

Further, the present invention provides a light source for irradiating visible light, a first holder for holding the light source so as to be able to swing around a predetermined axis, and a light source provided on the first holder. A driving member for a light source that swings around an axis to be rotated, a second holder that holds the first holder so as to be able to swing around an axis orthogonal to the axis, and a holder that holds the first holder around a corresponding axis. The drive member for the light source and the drive member for the holder are controlled such that the holder drive member to be oscillated, the processing portion of the wire harness related to the work sequence, and the component housing portion are simultaneously illuminated with the visible light. A work support instructing device comprising a control unit capable of being used.

According to this apparatus, the working order of each display position can be displayed by simultaneously irradiating the processing part of the wire harness and the component housing part which are related to the working order by visible light. Further, in this device, it is preferable that an elastic member is provided only between the first holder and the light source to prevent backlash of the reduction gear connected to the driving member for the light source.

According to this configuration, in order to swing the light source, the first holder is provided with the light source driving member, and the second holder for swingably holding the first holder via the light source driving member. Since the holder is provided, the holder driving member holds the light source driving member in a cantilever manner. As a result, the load on the driving member for the light source and the first holder held through the driving member for the light source is received by the driving member for the holder. There is no need to provide an elastic member.

FIG. 7 shows each motor 15 according to the embodiment of FIG.
FIG. 4 is a configuration diagram schematically showing a basic configuration for controlling the fourth and 156.

Referring to FIG. 7, a control unit 20 has a microprocessor 21 therein, and has, in its memory 22, a process of a wire harness WH to be manufactured, an irradiation position corresponding to each process, and an irradiation position. Are stored for each of the motors 154 and 156. These data are input using a personal computer (not shown). The CPU of the microprocessor 21
21a, each sensor S of the light beam irradiation unit 150 is provided.
1, and the output signals of S2 are input.

The microprocessor 21 includes:
In order to drive each of the motors 154 and 156 with higher accuracy, a motor control driver 2 is provided for each of the motors 154 and 156.
3a and 23b are connected, and each of the motors 154 and 156 can be selectively driven via these motor control drivers 23a and 23b.

An operation panel 24 is provided, and by operating the operation panel 24, the power supply is turned on and the light irradiation unit 1 is turned on.
The 50 light source units 160 can be forcibly turned off.

In addition, in the illustrated embodiment, the instruction signal output unit 171 and the continuity check signal output unit 172 of the connection instruction device 170 attached to the wiring board 2 are connected to the microprocessor 21. A connection instruction signal and a continuity test signal of the electric wire with terminal connected when the wire harness is manufactured are output from the respective output units 171 and 172. Thus, the processing step of the wire harness in the manufacturing process and the pass / fail judgment after the processing are input to the control unit 20, and the information can be used in a connection support procedure described later.

FIG. 8 is a flowchart showing the operation procedure according to this embodiment.

Referring to FIG.
Are initialized in step S1, and mode selection is performed in step S2. This mode selection includes a normal instruction processing mode S3 which is a normal routine,
This is for selectively switching to the teaching processing mode S4 for inputting data and changing settings.
Any mode is selected and executed by this mode selection procedure.

FIG. 9 is a flowchart showing details of the normal instruction processing mode in FIG.

Referring to FIG. 4, when the normal instruction processing mode is selected, the microprocessor 2 of the control unit 20
1 reads data to be displayed in step S31. In the reading operation according to the illustrated embodiment, the connection instruction signal output unit 1 of the connection instruction device 170 is used.
The process is input by reading the instruction signal output from 71. In the illustrated embodiment, the input information is collated with the data stored in the memory 22 in step S32. If the data does not match at the time of the data collation, the process proceeds to step S36, an error is displayed, and the process ends.

If the collated data match, in step S33, the light source unit 160 is operated to start lighting.

In the illustrated embodiment, as shown in FIGS. 10 to 12, which will be described later, the processing portion of the wire harness WH related to the work sequence and the corresponding component housing portion (case 4) are paired. In this case, the work order is displayed simultaneously with the visible light, so that the work order can be displayed without detecting the progress of the worker one by one. In this aspect, since the work position can be displayed simultaneously, there is no restriction over time, and it is easy to appropriately change the display state according to the work state of the worker.

Next, in step S34, the microprocessor 21 determines whether or not the worker has finished the work based on the output signal of the continuity test signal output unit 172 of the connection support device 170. If the output signal is a pass signal, the light source unit 160 is turned off in step S35, and the process ends. If the output signal is a reject signal in step S34, the flow advances to step S36 to display an error, and the process ends.

FIG. 10 is a perspective view showing a typical display example according to the present embodiment. In FIG. 10, reference numeral 2a denotes a wiring tool (so-called U) for arranging the wire harness WH.
And 4 is a case (component housing part) for housing articles required for the wiring harness WH to be routed, such as a connector or an exterior component attached to the wiring harness WH.
Alternatively, the above-described wiring tools 2a are accommodated by being appropriately classified by type.

As shown in FIG.
As a support display at the time of wire harness production by 0,
For example, it is preferable to irradiate and illuminate such that a linear trajectory GA is formed between the processing position of the wire harness WH and the case 4 corresponding thereto. As described above, the term “simultaneously” in the present invention is not limited to the “simultaneous” in the strict sense, but may be any degree as long as a human can identify the simultaneous with the locus GA of the visible light.

FIG. 11 is a perspective view showing a display mode according to another embodiment of the present invention.

As shown in FIG. 11, as a mode of irradiating the work position, a plurality of pointing devices 10 (or light beam irradiation units 150) are prepared, and a plurality of locations are simultaneously irradiated with visible light. Good.

FIG. 12 is a perspective view showing still another embodiment of the present invention.

In the example shown in the figure, the illuminations 5 are attached to the case 4 respectively, and the control unit 20 (see FIG. 6) can individually turn on the light at a predetermined timing. Then, the illumination 5 of the case 4 relating to the specific work process
By simultaneously illuminating the processing location of the wire harness WH corresponding to the case 4, a plurality of processes are simultaneously displayed.

The above embodiment is merely a preferred specific example of the present invention, and the present invention is not limited to the above embodiment. For example, as a light beam irradiation unit, by scanning and illuminating laser light by combining a plurality of mirrors,
A configuration that forms an optical image may be employed.

The irradiation timing is not limited to the above embodiment.

For example, the embodiment shown in FIG. 13 can be adopted. FIG. 13 is a flowchart according to another embodiment of the present invention. Note that among the contents shown in FIG.
The same reference numerals are given to portions having the same procedures as those described above, and description thereof will be omitted.

The procedure for setting the illumination timing as shown in FIG. 13 may be a method of counting the standard set time as shown in step S301. The standard setting time is a standard time required for the worker to perform the work, and is counted by a timer of the microprocessor 21 or the like. The operator performs a predetermined operation based on the lighting operation of the light source unit 160 within the standard set time. When such a standard setting time is set, the illumination is ended after the standard setting time has elapsed as shown in step S302, and also before the standard setting time has elapsed, as shown in step S303, Lighting can also be forcibly terminated by a manual operation (specifically, operation of the operation panel 24).
Accordingly, work support by lighting can be performed in a state more suitable for the work state of the worker, so that workability can be further improved.

It goes without saying that various modifications are possible within the scope of the claims of the present invention.

[0057]

As described above, according to the present invention,
Since a plurality of work orders are displayed at the same time, the display position switching operation by visible light becomes unnecessary as much as possible, and the work support is suitably performed even when manufacturing a wire harness having a relatively complicated process. It becomes possible. Further, even when the display position is switched by setting a timer or the like, a plurality of processes are displayed at the same time, so that the setting is facilitated, and the deviation from the actual working time of the operator is less likely to occur. Therefore, according to the present invention, there is a remarkable effect that the manufacturing procedure of the wire harness can be displayed with a configuration as simple as possible.
