Description

Harness cable marking device {The Harness Cable Marking Device}

The present invention relates to a harness cable marking device.

As the number of electrical components in automobiles increases, harnesses that play the role of 'neural networks' are becoming more complex and increasing in number. A harness is literally a part made by connecting bundles of wires and weaving them together in the shape of a mountaineering military vest.

The harness supplies power to operate automotive electrical components and transmits electrical signals to each control unit or arithmetic unit. As a car neural network, the harness is generally pre-installed in the required location before body assembly. Harnesses are classified according to their positions and roles, such as a main harness, a front harness, a control harness, and a floor harness, and the number of harnesses tends to increase.

Recently, as the number of sensors for functions such as self-driving electric vehicles increases, this neural network is also becoming complex enough to be difficult to compare with past cars.

Harness is a very labor-intensive industry in which people have to twist and connect each other, and the harness is made of a lot of wires, such as 500 kinds of wires.

For this harness work, the current wire sheathing color is differentiated. However, even if the colors are different, the number of wires may be very large, and the colors may overlap, and it is difficult to distinguish wires having different thicknesses.

In addition, in order to produce wires with different sheath colors, it should be easy to replace materials for each sheath color, but to prevent color mixing, it is necessary to melt and discharge a large number of them, so the utilization rate of wire sheath production is low at about 55%. am.

The present invention has been devised with the above technical background, and the present invention is a harness cable that can recognize the pin number of each wire while unifying the wire coating color constituting the harness, and can increase manufacturing efficiency by marking the pin number on both ends of the wire at the same time. It's about marking devices.

1 is a conceptual diagram illustrating wires connected to a cable harness connector manufactured by a harness cable marking device according to an embodiment of the present invention.

Referring to FIG. 1 , a wire 100 according to an embodiment of the present invention may be connected to a cable harness connector 200 . The wire sheath 110 may have the same sheath color.

The cable harness connector 200 is a total assembly of wires that enables each system to perform its proper role by transferring electrical signals and currents generated in each part of automobiles and electronic products between parts. The cable harness connector 200 is an intermediate medium that electrically interconnects numerous electrical components mounted in a vehicle, transfers electrical energy generated from a generator to each electrical component, and transmits various information generated from various switches and sensors to the corresponding component. As such, it serves as an electrical pathway.

A plurality of pins 210 may be provided inside the cable harness connector 200 . Each of the plurality of pins 210 may be connected to the plurality of wires 100 one-to-one.

At the end of the wire 100 according to an example, printed contents 120 printed by a wire marking device along the circumference of the wire 100 may be printed. For example, the printed contents 120 may be formed in a plurality of colors. In addition, the printed content 120 may be formed by varying the thickness for each color. In addition, a plurality of printed contents 120 may be formed on one wire sheath 110 spaced apart at predetermined intervals. The printed contents 120 may be symmetrically printed on one end and the rear end of one wire sheath 110 . Accordingly, the same printed contents 120 can be confirmed in the harness connector 200 connected to one end of the wire 100 and the rear end connector connected to the rear end.

Accordingly, in one embodiment of the present invention, it is possible to fabricate a wire capable of recognizing the pin number of each wire while unifying the coating color of the wire constituting the harness. In addition, since the wires can be easily distinguished, maintenance of the harness can be performed. Also, since it is not necessary to completely replace the harness, costs can be reduced.

As another example, a plurality of printed contents 120 may be printed by being spaced apart by a predetermined interval between one end and the rear end of one wire covering 110 . That is, when the length of the wire 100 is long, the same printed content 120 as one end and the rear end may be printed in the middle of the wire 100. Accordingly, the wires can be more easily distinguished even in the long wire 100 .

2 is a plan view of a harness cable marking device according to an embodiment of the present invention, FIG. 3 is a side view of FIG. 2 viewed from A direction, and FIG. 4 is a side view of FIG. 2 viewed from B direction.

2 to 4, the harness cable marking device 300 according to an embodiment of the present invention includes a print control unit 310, a print head unit 320, a PLC unit 330, a conveyor unit 340, A fixed part 350 and a moving part 360 may be included.

The print control unit 310 may set the printing content to be printed according to the positions of the pins on both ends of the plurality of wire sheaths 110 located inside the harness to which connectors made of a plurality of pins are connected at both ends. The print control unit 310 may include a print section control unit 311 that sets a printing point of the wire covering 110 .

The print section control unit 311 may set a print section before a printing point. The print section may be set to a length to be inserted into the connector, a length to be printed apart from the connector, and a length to be spaced apart from the connector.

The length to be inserted into the connector may be the length in which the wire is inserted into the connector to be connected to the pin when connecting the wire to the connector. The length to be printed is a portion spaced apart from the connector by a predetermined distance so that the printed content can be observed well, and may be an area where the printed content is printed. The distance apart from the connector may be a length between a length in which the wire is inserted into the connector and a length in which printed contents are printed.

The same printed contents may be printed on both ends of one wire sheath 110 . In this case, the printed contents may be formed symmetrically from the center of the wire covering 110 . For example, printed contents may be formed in a plurality of colors on both ends of the wire sheath 110 . In addition, printed contents of different colors may be formed on each of the plurality of wire sheaths 110 so as to be easily distinguished. For example, printed contents may be formed on the wire sheath 110 by varying the thickness for each color. The printed contents may include a plurality of printed contents formed thinly or thickly for each color. The thickness and number of printed contents may be variously set according to the type and number of wire sheaths 110 . However, in order to easily distinguish each of the plurality of wire coverings 110, the printed contents may not overlap.

As another example, the printed contents may be made in the form of color codes. For example, the printed contents may be in the form of uncomplicated codes. The code may be variously formed such as Morse code, star, triangle, and square. In addition, the above-mentioned printing contents having different thicknesses and the printing contents in the form of codes may be mixed.

As described above, in one embodiment of the present invention, it is possible to fabricate a wire capable of recognizing the pin number of each wire while unifying the coating color of the wire constituting the harness by setting the contents of printing in various ways. In addition, since the wires can be easily distinguished, maintenance of the harness can be performed. In addition, since the entire harness does not need to be replaced, costs can be reduced.

The print head unit 320 may print the print contents 120 on both ends of the wire covering 110 . The print head unit 320 may include a first print head unit 321 and a second print head unit 322 . The first print head unit 321 and the second print head unit 322 may be spaced apart from each other by a predetermined distance and arranged symmetrically with respect to the center of the wire covering 110 . The first print head unit 321 and the second print head unit 322 are connected to the moving unit 360 and may move in different directions according to instructions from the PLC unit 330 . For example, the distance from the center of the wire sheath 110 to the first printhead unit 321 and the distance from the center of the wire sheath 110 to the second printhead unit 322 may be set to be the same. Accordingly, the same printed contents can be simultaneously printed at symmetrical positions on both ends of the wire covering 110 .

Since one embodiment of the present invention unifies the color of the cables and distinguishes the wires by marking lines or codes of different thicknesses on the cables, the number of wire sheaths 110 is correlated with only the two printer heads provided at both ends. It can print and distinguish various types of print contents without In addition, since the print head unit 320 can be moved according to an embodiment of the present invention, printing contents can be easily printed in various printing sections set according to the length of the wire covering 110 .

The PLC unit 330 may receive a printing section from the printing section control unit 311 and move the print head 320 connected to the moving unit 360 to the printing section. For example, a print section may be set according to the length of the wire covering 110 stored in the print control unit 310 . In this case, the PLC unit 330 may move the printer head unit 320 according to the length of the wire covering 110 so that the printer head unit 320 is located in the printing section. In addition, the PLC unit 330 may receive print contents to be printed on each wire covering 110 and instruct the operation of the print head unit 320 .

The conveyor unit 340 supports the plurality of wire sheaths 110 and may move the plurality of wire sheaths 110 in the printing direction in which the print head unit 320 is provided. For example, a bundle of a plurality of wire sheaths 110 may be simultaneously injected into the harness cable marking device 300 . First, the plurality of wire sheaths 110 may be seated side by side on the conveyor unit 340 at a predetermined interval. Next, as the conveyor unit 340 is rotated and disposed at the lower end of the printer head unit 320 sequentially, printing contents can be printed in the printing section.

The fixing part 350 is provided at both ends of the wire sheath 110 to fix both ends of the wire sheath 110 . For example, when the wire sheath 110 is supplied to the harness cable marking device 300, the wire may be bent or twisted as the thickness of the wire sheath 110 becomes thinner. In this case, printing defects may occur on the wire covering 110 . To prevent this, the fixing part 350 may hold the wire sheath 110 at the top and bottom of the wire sheath 110 . At this time, the width of the fixing part 350 may be larger than the width of the wire covering 110 . Accordingly, in one embodiment of the present invention, it is possible to improve print quality by preventing the wire sheath 110 from being bent or distorted.

The moving unit 360 is connected to the printer head unit 320 and can move the printer head unit 320 according to instructions from the PLC unit 330 . The first print head 321 may be connected to one end of the moving unit 360 and the second print head 322 may be connected to the other end. The moving unit 360 may receive the printing section of both ends of the wire sheathing 110 from the PLC unit 330, respectively, and move the first printer head unit 321 and the second printer head unit 322 at the same time. In this case, the first print head 321 and the second print head 322 may move in different directions and be symmetrically arranged. Accordingly, the same printed contents can be symmetrically printed on both ends of the wire covering 110 .

According to the configuration as described above, in one embodiment of the present invention, it is possible to fabricate a wire capable of recognizing the pin number of each wire while unifying the coating color of the wire constituting the harness. In addition, one embodiment of the present invention can reduce the number of wires, thereby reducing the weight of the vehicle. In addition, since the wires can be easily distinguished, maintenance of the harness can be performed, and cost can be reduced because the entire harness does not need to be completely replaced during maintenance.

In addition, in one embodiment of the present invention, since the wire coating can be injected into the marking device in a bundle, the loading time of the wire coating can be reduced. In addition, according to an embodiment of the present invention, printing time can be reduced by simultaneously printing the contents on both ends using two printer heads, thereby improving work yield.

5 is a view showing a fixing part according to another embodiment of the present invention.

Referring to FIG. 5 , the fixing part 350 according to another embodiment of the present invention may include a rotating member 355 provided on the rear side. For example, the rotating member 355 is coupled to the center of the rear surface of the fixing part 350 to rotate the wire sheath 110 by 180°. First, the print head unit 320 may print the printed content 120 on the upper surface of the wire covering 110 according to the moving direction of the wire covering 110 . Next, in order to ring-mark the wire sheath 110, the rotating member 355 may rotate the wire sheath 110 by 180°. Accordingly, the lower surface of the wire sheath 110 may be disposed to face upward. Next, the same printed content 120 as the upper surface may be printed on the lower surface of the wire sheathing 110 .

In another embodiment of the present invention, since the rotating member 355 is provided, ring marking can be performed without adding a printer head to the lower portion of the wire sheath 110. Accordingly, printing contents can be printed on a plurality of wire-covering bundles while reducing cost and time.

6 is a conceptual diagram showing printing contents according to an embodiment of the present invention.

Referring to FIG. 6 , printed contents 110 according to an embodiment of the present invention may be formed in a plurality of colors along the circumference of the wire 100 at the end of the wire 100 . The printed contents 110 may be formed on the wire covering 100 by varying the thickness for each color. For example, the thickness may be varied according to the pin number (PIN NO.) of the wire covering 100. When the pin number is 1 to 4, 1 to 4 thinly printed contents can be printed. If the pin number is 5, one print content thicker than that used for 1 to 4 can be printed. If the pin number is 6, one thick print content used for 5 and one thin print content used for 1 may be combined and used. If the pin number is 10, 2 of the thick print content used for 5 can be used.

As another example, the printed contents 110 may be formed in the form of color codes. That is, the code form can be changed according to the pin number of the wire sheath. When the pin numbers are 1 to 4, 1 to 4 blank star-shaped printed contents (☆) may be printed. If the pin number is 5, one printed content (★) in a star shape can be printed. If the pin number is 6, one full star-shaped printed content (★) used for 5 and one hollow star-shaped printed content (☆) used for 1 can be combined and used (★☆). If the pin number is 10, 2 printed contents (★) in the form of a solid star used for 5 can be used (★★).

As another example, the printed content 110 may be formed in the form of a color Morse code. The Morse code may be a code for transmitting messages composed of a combination of dots and lines. For example, if the pin number is 1, one dot and four lines may be printed, if the pin number is 5, five dots may be printed, and if the pin number is 0, five lines may be printed. can

As described above, according to one embodiment of the present invention, it is possible to fabricate a wire capable of recognizing the pin number of each wire while unifying the coating color of the wire constituting the harness. In addition, since the wires can be easily distinguished, maintenance of the harness can be performed. In addition, since the entire harness does not need to be replaced, costs can be reduced.
