Description

Description: TECHNICAL FIELD The present invention relates to an automatic wiring device for manufacturing a bundled wire (wire harness) used for a switchboard, a control panel, etc., and particularly to an end treatment of the wire and the bundled wire. The present invention relates to an automatic wiring device suitable for consistent formation and formation.

[Prior Art] As described in JP-A-61-23399, a conventional automatic wiring device uses a nozzle-shaped tool between auxiliary tools such as nails provided on a wiring board. Wires are drawn around to form a bundle. According to this conventional device, the electric wire is continuously drawn from the reel, and becomes a plurality of electric wires after being completed as a bundled wire. However, since it is formed with one continuous electric wire, after cutting the end part after forming the appearance of the bundled wire,
Work such as peeling off the covering material and crimping the terminals is required. In these operations, the wires are already formed into a bundle shape, so automation is difficult and it has to rely on human labor, which not only hinders the integrated automation of the bundle wire manufacturing process, but also requires manual terminal crimping. Therefore, an error occurs, which is a cause of adversely affecting the reliability of the product.

An apparatus for automatically performing terminal processing is disclosed in Japanese Patent Laid-Open No. 60-233898. In this conventional device, an electric wire is cut into a required length, both ends of the electric wire are gripped, and first an end processing is performed at a terminal processing device. Then, one end of the electric wire subjected to the terminal treatment is locked to a predetermined holder, and the other end side is laid along a predetermined path of the wiring board for wiring. In this way, many electric wires are laid and a bundle is formed.

[Problems to be Solved by the Invention] The prior art described in Japanese Patent Laid-Open No. 60-233898 aims to automate the terminal processing and achieves integrated automation of the bundle wire manufacturing process. However, since terminal processing and bundle formation are performed in a series of operation sequences, there is a problem that bundle formation cannot be performed during terminal treatment and terminal treatment cannot be performed during bundle formation, resulting in poor work efficiency. . Further, when creating control information for controlling the bundle forming device and the terminal processing device, since the terminal processing control and the wiring (bundle forming) control are performed in a series of operations, the information creation becomes complicated and a lot of labor is required. There is a problem that it becomes necessary.

It is an object of the present invention to provide an automatic wiring device that can perform terminal processing and bundle formation automatically and efficiently and that can easily create control information.

[Means for Solving Problems] The above-mentioned object is to measure and cut each electric wire that constitutes a bundle wire to perform end treatment on both ends or one end of the electric wire, and to terminate the treated electric wire to a wire rod transfer unit. While holding the electric wire on the terminal processing section and the wire rod delivering section, the electric wire is formed along the required path on the wiring board, and the electric wire is repeatedly formed by a predetermined number of bundles. A bundle line forming unit that forms a line, a terminal processing unit control unit and a bundle line forming unit control unit that respectively control the terminal processing unit and the bundle line forming unit, and control information to be given to the respective control units are created. It has a programming department.

The bundling portion is provided with a starting head and a terminating head that are respectively movable on the wiring board, a starting grip that is attached to the starting head and that grips the starting end of the wire, and draws the wire along a predetermined path. It has a nozzle and an end grip attached to the end head and for gripping the end of the wire.

In addition, the programming unit includes hoard data indicating the coordinate values of nails and holders provided on the wiring board, the wire diameter of each electric wire, the wire type of the covering material, the processing content of the starting end, the processing content of the end, and the cloth. When standard data consisting of wire data indicating the route of electric wires on the wire board and sub-harness data indicating the formation unit of each bundle as a set of multiple electric wires is input, these data are converted to standard data. When a standard data creation program means to be registered as a file and specified sub-harness data is specified, necessary data is extracted from the standard data file and edited, and a work file corresponding to the specified sub-harness data is created to edit data. The program means, the route on the wiring board, the contents of the circumference of the nail, and the route of the electric wire should move the start end grip, end grip, and nozzle. According to the operation decision rules for determining the road,
An operation determination program means for creating an operation data file capable of determining the movement paths of the start head and the end head of the bundle forming section, and the terminal processing section control section and the bundle forming section control section based on the operation data file. A standard data creation program means for converting the bundle forming section into data content capable of controlling the standard data creation program means,
Data editing program means, operation determination program means,
The data output program means is configured to collectively create the operation information of the terminal processing section and the operation information of the bundle forming section based on the standard data.

Further, the terminal processing unit control unit, the bundle line forming unit control unit,
They are connected to each other via a communication line, and based on the operation information of the terminal processing unit and the operation information of the bundle forming unit, the other can execute the processing while one of the terminal processing unit and the bundle forming unit is processing. Therefore, the terminal processing unit and the bundle forming unit are configured to be controlled independently.

[Operation] As described above, when the programming unit inputs standard data consisting of board data, wire data, and sub-harness data, standard data creation program means for registering as a standard data file and predetermined sub-harness data Is specified, a data editing program means for creating a work file corresponding to predetermined sub-harness data, and an operation determining program for creating a data file capable of determining the moving paths of the start end head and the end head of the bundle forming part. And a data output program means for converting the terminal processing unit control unit and the bundle line forming unit control unit into data contents that can respectively control the terminal processing unit and the bundle line forming unit based on the operation data file. By programming means
Since the operation information of the terminal processing unit and the operation information of the bundle forming unit are collectively created based on the standard data, the control information of each of the terminal processing unit and the bundle forming unit is collectively prepared from the same wiring information. Therefore, it is possible to reduce the effort for creating a program.

Moreover, the motion determining program means follows the motion determining rule for determining the route to the starting end grip or the end grip and the route to move the nozzle from the route of the wiring board, the content of the lap of the nail, and the route of the electric wire. Since the movement path of the end head and the end head can be determined, automatic wiring can be performed easily and reliably even if the path of the target harness and the wire material forming the harness changes.

The terminal processing section performs terminal processing on the electric wire based on the operation information obtained from the programming section, and sequentially conveys the terminal-processed electric wire to the wire rod delivery section, while the bundle forming section is based on the operation information obtained from the programming section. Then, the terminal processing unit receives the processed electric wire and forms the electric wire along a predetermined path. Further, the bundle forming unit outputs a signal indicating the completion of receiving the electric wire, and instructs the terminal processing unit to prepare to supply the next electric wire. The transmission of each of the above information is performed via a communication line.

With this, the control information of each of the terminal processing unit and the bundle forming unit can be obtained collectively from the same wiring information, which can reduce the effort for creating a program, and the terminal processing unit and the bundle forming unit. The work efficiency can be improved because the work is performed simultaneously with the forming unit.
