Description

  The present invention is used for instructing the production of a three-dimensional structure formed by a plurality of wire harnesses on a wiring board, and is a planar manufacturing that supports creation of a planar manufacturing drawing in which the three-dimensional structure is developed into a planar shape. The present invention relates to a drawing production support device, a plan production drawing creation support method, and a plan production drawing creation support program.

  Various electronic devices are mounted on automobiles or the like as moving bodies. For this reason, the automobile or the like is wired with a wire harness in order to transmit electric power from a power source, a control signal from a computer, or the like to the electronic device. The wire harness includes a plurality of electric wires and connectors attached to ends of the electric wires.

  The electric wire includes a conductive core wire and a covering portion made of an insulating synthetic resin that covers the core wire. The electric wire is a so-called covered electric wire. The connector includes a conductive terminal fitting and an insulating connector housing. The terminal fitting is attached to an end portion of the electric wire and is electrically connected to the core wire of the electric wire. The connector housing is formed in a box shape and accommodates the terminal fitting.

  When assembling the wire harness, the electric wire is first cut to a predetermined length, and then a terminal fitting is attached to the end of the electric wire. Connect wires as needed. Thereafter, the terminal fitting is inserted into the connector housing. Thus, the wire harness described above is assembled.

  The design of the wire harness is prepared in parallel with the design progress of the vehicle or the like in which the wire harness is routed. Usually, a route layout of a wire harness is requested by a manufacturer such as a vehicle (simply called a car manufacturer), and a component manufacturer that receives the request uses a manufacturing jig to manufacture a wire harness that satisfies the request. Specifically, a car manufacturer generates circuit information indicating, for example, a product type, a size, a circuit, and the like by circuit design, and based on the circuit information, performs a three-dimensional route plan in consideration of an auxiliary device, a fixed position, a body shape, and the like. The route plan information shown is created. Then, the operator converts the three-dimensional wire harness indicated by the route plan information into a two-dimensional (planar shape) by manual operation or the like to create a two-dimensional (planar) manufacturing drawing, and the two-dimensional manufacturing drawing that has been drawn out. Based on this, the manufacturer was instructed to manufacture a wire harness.

Further, Patent Literature 1 describes a wire harness design support method that can easily convert three-dimensional data of a wire harness into a two-dimensional drawing. In this patent document 1, a development plane for two-dimensionally developing the wire harness data is set, the wire harness data is divided into a plurality of segments for each predetermined division point, and all the segments are used as the development plane. It is possible to easily convert the three-dimensional data of the wire harness into a two-dimensional drawing by expanding each segment so as to be included, and the design period of the wire harness has been shortened.

The evaluation result information indicating the evaluation result is output to the display device 10 to display the evaluation result on the display device 10 to the designer (W3).

  The designer refers to the evaluation result, and when there is a defective portion such as a portion where the three-dimensional structure 2 manufactured on the wiring board 8 cannot be mounted on the mounting target, a route planning step (W3). Returning to FIG. 5, the design change of the route plan information D2 for the defective part is performed, and the plan manufacturing drawing creation support process is performed again (W4). On the other hand, if no defect location is found in the evaluation result, the designer issues a plan manufacturing drawing, and the car maker or the like instructs the manufacturing meter or the like to manufacture the three-dimensional structure 2 based on the plan manufacturing drawing (W4).

  Manufacturing meters, etc. are examined based on the above-mentioned plan manufacturing drawings, considering the wiring board 8 used for manufacturing, manufacturing jigs, jig layouts, etc., manufacturing of vehicle feasibility evaluation, etc. In the case of failure, the failure information is notified to the car manufacturer.

On the other hand, if there is no problem in the examination result of the process W5, the three-dimensional structure 2 instructed to manufacture in the plan view is manufactured in a plane shape on the wiring board 8 (W6).

  According to the plan production drawing creation support apparatus 10 of the present invention described above, the layout shape model M1 considering the production requirements is formed by acquiring the route plan information D2 and the production requirement information D3, and the mounting shape model M2 is obtained. Since the evaluation is performed based on the simulation result of the deformation to the shape, and the evaluation result is output to support at least one of the route design of the three-dimensional structure 2 and the creation of the plan production drawing, a plan production drawing is created. Since the factor of the design change can be reduced at the stage where the route plan information D2 before the creation is created, the accuracy of the route plan information D2 can be improved. Accordingly, the accuracy of the plan drawing created based on the route plan information D2 can be improved and the occurrence of defects in the manufacturing process can be reduced, so that the transition from the design process to the manufacturing process can be made more efficient. . Moreover, since it can contribute to reduction of the examination man-hour in a manufacturing process, elimination of trial manufacture of a manufacturing jig etc., the life cycle of the three-dimensional structure 2 can be shortened.

  Further, since the circuit information D1 of the three-dimensional structure 2 is acquired and the layout shape model M1 is created based on the circuit information D1, the route plan information D2, and the manufacturing requirement information D3, the circuit structure D1 is connected to the wire harness. Since the direction of the connector and the like can be taken into account, the deformation from the layout shape model M1 to the mounting shape model M2 can be simulated more accurately. Therefore, since the completeness of the planar manufacturing drawing created based on the route plan information D2 can be further improved, the occurrence of design changes can be reduced.

  In the above-described embodiment, the case where the design device 5, the manufacturing requirement information providing device 7, and the plan production drawing creation support device 10 are realized by separate devices has been described.
