It becomes possible to perform the routing work.
[0066]
Referring to FIG. 9, the assembly drawing plate 210 is provided with a container 218 and a tray 219 that house exterior parts connected to the subassembly assembly SH in the assembly process. In addition, an assembly process support unit 220 for supporting a mounting procedure for mounting these exterior parts is incorporated. The assembly process support unit 220 selectively turns on a lamp (not shown) at regular intervals by the controller 221, thereby displaying the mounting location and the components to be mounted and displaying the connection procedure to the operator. Is to do. In the illustrated example, the assembly drawing board 210 is provided with a start switch 222, a stop switch 223, and an end switch 224 so that the connection operation by the controller 221 can be controlled manually. Further, a progress guide display unit 225 similar to the progress guide display unit 125 provided on the connection work table 100 is connected to the controller 221.

Then, the operator operates the start switch 222 to cause the controller 221 to perform a display operation, and attaches exterior parts at a pace displayed on the progress guide display unit 225. The controller 221 is set to turn off the current display lamp and turn on the display lamp at the next connection location when a preset display time has elapsed. Also, if the worker cannot finish the connection work within the display time for some reason, the controller 221 displays the current display operation as it is by operating the stop switch 223. The operation is set so as not to move to the next step. Further, the controller 221 can perform display support for the post-process by the operator operating the start switch 222 again when the work catches up.
[0068]
Then, when the worker P operates the end switch 224 after the work is finished, the controller 221 finishes the display process.

FIG. 19 is a schematic sectional view showing one step in the assembly station.
[0071]
First, referring to FIG. 1 and FIG. 11, in the above configuration, first, the worker P operates the connection support unit 120 of the connection station ST1 to perform a connection process. In this connection step, the connection support unit 120 displays the connection of the subassembly S to be connected first, and the worker P takes out the subassembly S to be connected from the stock table 300 and instructs to attach the connector C. The connector holder 121 is attached. When the connector C is attached to the connector holder 121, the detector of the connector holder 121 and the terminal of the connector C come into contact with each other, so that the control unit 122 of the connection support unit 120 determines whether the attachment is good. If the mounting is good, the control unit 122 gives the next mounting instruction (the connection order is indicated by a circled number in FIG. 11). When all the connectors C are attached, the connection support unit 120 issues a connector attachment instruction for the next subassembly S.
[0072]
The designation of the subassembly S at this time can be easily specified, for example, by stocking the subassembly S on the stock table 300 by type and numbering the connection order of the subassembly S.
[0073]
As shown in FIG. 12, some subassemblies S include a later insertion terminal T connected to a connector C of another subassembly S in a later process. In this case, after all the connectors C of the sub-assembly S are mounted on the connector holder 121 in accordance with the mounting order, the rear-insertion terminal T is brought into contact with the grounding plate (not shown), and the voltage drop at that time causes a later-insertion terminal. It becomes possible to specify T. As a result, the control unit 122 can display a cavity into which the insertion terminal T is to be inserted thereafter on a display lamp (not shown) provided in the connector holder 121 and can instruct the operator to connect.
[0074]
  Referring to FIG. 13, a relatively large-scale sub-assembly assembly SH is manufactured on connection diagram board 110 of connection work table 100 by performing the connection process by repeating the mounting / connection work. Become. At this time, each connector C constituting the subassembly assembly SH has the connector holder 121 of the subassembly assembly SH.Narrower than final formBy being arranged in the work area, the connection process can be completed without performing useless operations. Further, in this connection step, the cut piezoelectric wire W that constitutes the trunk portion of the sub-assembly assembly SH is wired on the detachable plate 142 of the trunk wire holder 140 that is mounted on the connection diagram board 110 in advance. At this time, the surrounding plate 143 of the trunk wire holding tool 140 is in an open posture so that the cut piezoelectric wire W can be easily wired on the detachable plate 142. There is no hindrance.
[0075]
Next, when all the connection processes are completed, as shown in FIGS. 14 and 15, the worker P takes out some of the connectors C from the connector holder 121 and removes the manufactured sub-assembly assembly SH from the terminal processing unit 150. Develop on ~ 170.
[0076]
By this development process, the sub-assembly assembly SH is routed in the final form on the connection work table 100. In this state, the worker P performs terminal processing of the sub-assembly assembly SH in a predetermined procedure. In this terminal processing, for example, an exterior part (corrugated tube CL is shown as an example of the exterior part in FIGS. 14 and 15) accommodated in the containers 111 and 112 is attached, or taping is performed to Prevent looseness from occurring. In this process, since the terminal processing is performed in a state where the trunk portion of the sub-assembly assembly SH is wired, the finished dimension of the terminal portion is precisely maintained at the intended size. Further, through this process, the sub-assembly assembly SH becomes the sub-assembly assembly bundle GH.
[0077]
Next, referring to FIG. 16 and FIG. 17, when the terminal processing is completed, the worker P shifts to a transporting process of transporting the manufactured subassembly assembly bundle GH from the connection station ST1 to the assembly station ST2. In this transporting process, the surrounding plate 143 of the trunk wire holding tool 140 is displaced from the open posture shown in FIG. 16 to the surrounding posture shown in FIG. 17, and the sub-assembly assembly bundle GH is removed from the connection work table 100 in a state of surrounding the trunk portion. Remove.
[0078]
Then, as shown in FIG. 18, the sub-assembly assembly bundle GH is transported to the assembly drawing plate 210 of the assembly work table 200 for each main wire holder 140, and the notch 143a is preset as described in FIG. The main wire holder 140 is temporarily placed on the assembly drawing plate 210 in a state where it can be detached from the sub-assembly assembly SH, as shown in FIG. The sub-assembly assembly SH can be held by the assembly drawing board 210 as it is.
[0079]
After this conveyance process is completed, the final wiring harness WH is manufactured by mounting an exterior part (the protector PA is shown in FIG. 1 as an example of the exterior part) on the assembly drawing board 210.
[0080]
As described above, according to the present embodiment, the connection support unit 120 installed on the connection work table 100 of the connection station ST1 can perform the connection work in a relatively compact work area, and the same The terminal assembly units 150 to 170 provided in the connection station ST1 can expand the subassembly aggregate SH into a final form, and perform a post-process to process the subassembly aggregate bundle GH. For this reason, it is possible to transport the sub-assembly assembly bundle GH, which is subjected to terminal processing and whose form can be specified, from the connection station to the assembly station. As a result, in the process of transporting the sub-assembly assembly bundle GH to the assembly drawing board 210, it is possible to prevent the terminal portion from being scattered or entangled as much as possible.
[0081]
Moreover, in this embodiment, the main line holder 140 is previously attached to the connection drawing plate 110 and the connection work is performed, so that the main line portion of the sub-assembly assembly SH can be held by the main line holder 140 during the connection work. At the time of transportation, the subassembly assembly bundle GH is removed from the connection drawing plate 110 together with the main wire holder 140 to convey the subassembly assembly bundle GH to the assembly drawing plate 210 while maintaining the form of the main line portion. Therefore, it becomes easier to transport and maintain the shape of the sub-assembly assembly bundle GH.
[0082]
