Description

Technical Field

[0001] The utility model relates to the technical field of wire harness tracing technology, in particular to an overall wire harness tracing system. Background Art

[0002] Wiring harnesses are usually composed of multiple wires or conductors and are used to transmit electrical signals from one point to another. They are widely used in automobiles, aircraft, and electronic equipment. Especially with the promotion of green travel, wiring harnesses are used as key components in new energy vehicles for transmitting and connecting power, information, and data.

[0003] Since the number of manufacturing processes of the wiring harness assembly line for new energy vehicles is increasing, especially the number of processes and workstations after the finished wiring harness is off the line, the wiring harness is missed for inspection and the wiring harness products frequently skip the workstation and are missed for inspection. At the same time, after the wiring harness products leave the factory, it is impossible to trace the data of the wiring harness products in time and determine whether the wiring harness products have completed all processes. Utility Model Content

[0004] The utility model aims to provide an overall wire harness tracing system, which stores data for each process in the production process of a wire harness assembly line to form a tracing system that can be traced and queried.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] 1) An overall wiring harness tracing system, comprising:

[0007] An RFID tag disposed on the finished wire harness is configured to store manufacturing information of the finished wire harness;

[0008] Several RFID readers are arranged in the offline process of the finished wire harness, each RFID reader corresponds to a corresponding offline process, and the RFID reader is configured to read the manufacturing information of the RFID tag on the finished wire harness;

[0009] The server is configured to be electrically connected to the RFID readers in all offline processes of the finished wire harness, obtain the manufacturing information, or the manufacturing information and incremental detection information, read from the RFID tag in the RFID reader, and supplement the detection information in the offline process into the RFID tag and store it in the server.

[0010] This solution builds a radio frequency traceability system between the RFID tags on the finished wire harness each time it is manufactured and several RFID readers in the offline process of the finished wire harness; each time a finished wire harness is manufactured, an RFID tag is added to the finished wire harness, and the RFID tag stores the manufacturing information of the finished wire harness. In this way, in the offline process of the finished wire harness, the manufacturing information of the finished wire harness manufactured online can be detected and obtained, so that the online data and the offline data are connected.

[0011] The RFID readers installed in all processes of the finished wire harness off the line can read the RFID tags on the finished wire harness. During the reading process, the RFID reader transmits the read information to the server in a cumulative state. For example, the manufacturing information read by the RFID reader in the first process is transmitted to the server. While obtaining the RFID tag, the server adds the detection information of the first process to the RFID tag and stores it in the server. When the RFID reader reads in the next process, it will read the manufacturing information and the detection information of the previous process at the same time. In this way, the RFID reader reads the information in a continuous cumulative state. If a fault occurs, it can be judged that the wire harness has missed the inspection and the finished wire harness needs to be supplemented with additional inspection.

[0012] 2) A whole harness traceability system according to 1), wherein:

[0013] It also includes several alarms, each of which corresponds to a corresponding finished wire harness offline process, and the alarm has a matching number with the RFID card reader in the finished wire harness offline process, and all alarms are electrically connected to the server.

[0014] In this solution, each alarm corresponds to a corresponding finished wire harness offline process, so that the finished wire harness offline process corresponds to the alarm one by one, and there is a matching number between the RFID reader and the alarm in the finished wire harness offline process; in this way, when a fault occurs in the finished wire harness offline process, the RFID reader of the finished wire harness offline process fails to read the RFID tag information in the finished wire harness, and the RFID reader feeds back a no-read signal to the server. At this time, the server knows which finished wire harness offline process has not been detected based on the RFID reader. At this time, the alarm on the finished wire harness offline process will be activated to sound an alarm, so that the undetected finished wire harness offline process can be quickly located, and the finished wire harness can be supplemented with detection.

[0015] 3) A whole harness traceability system according to 1), wherein:

[0016] The RFID tag is attached to the tail of the finished wire harness along the transmission direction of the offline process.

[0017] This design can meet the requirement that when the finished wire harness is inspected along the transmission direction of the offline process, after the finished wire harness is inspected, the RFID tag at the end of the finished wire harness is read by the RFID reader in the offline process of the finished wire harness. While reading, the server will add the inspection information to the RFID tag and store it in the server.

[0018] 4) A whole harness traceability system according to 2), wherein:

[0019] The alarm is fixed at the head of the finished wire harness off-line process along its transmission direction.

[0020] With this design, when a fault occurs in the RFID reader, the server activates the alarm. The alarm is fixed at the head of the finished wire harness offline process along its transmission direction, so that the alarm sound or alarm light can better alert the staff at the back end of the finished wire harness offline process.

[0021] Compared with the prior art, the utility model also has the following technical effects:

[0022] The utility model constructs a radio frequency traceability system between the RFID tags on the finished wire harness each time it is manufactured and several RFID readers in the off-line process of the finished wire harness. In the production process of the wire harness assembly line, data is stored for each process to form a traceability query traceability system. After the wire harness product leaves the factory, the data of the wire harness product is traced and queried in time to determine whether the wire harness product has completed all processes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 This is a framework diagram of an overall wiring harness tracing system of the utility model. DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] For example, see Figure 1 As shown, in this embodiment, an overall wire harness traceability system includes an RFID tag disposed on a finished wire harness, and is configured to store manufacturing information of the finished wire harness;

[0026] Several RFID readers are arranged in the offline process of the finished wire harness, each RFID reader corresponds to a corresponding offline process, and the RFID reader is configured to read the manufacturing information of the RFID tag on the finished wire harness;

[0027] The server is configured to be electrically connected to the RFID readers in all offline processes of the finished wire harness, obtain the manufacturing information, or the manufacturing information and incremental detection information, read from the RFID tag in the RFID reader, and supplement the detection information in the offline process into the RFID tag and store it in the server.

[0028] This solution builds a radio frequency traceability system between the RFID tags on the finished wire harness each time it is manufactured and several RFID readers in the offline process of the finished wire harness; each time a finished wire harness is manufactured, an RFID tag is added to the finished wire harness, and the RFID tag stores the manufacturing information of the finished wire harness. In this way, in the offline process of the finished wire harness, the manufacturing information of the finished wire harness manufactured online can be detected and obtained, so that the online data and the offline data are connected.

[0029] The RFID readers installed in all processes of the finished wire harness off the line can read the RFID tags on the finished wire harness. During the reading process, the RFID reader transmits the read information to the server in a cumulative state. For example, the manufacturing information read by the RFID reader in the first process is transmitted to the server. While obtaining the RFID tag, the server adds the detection information of the first process to the RFID tag and stores it in the server. When the RFID reader reads in the next process, it will read the manufacturing information and the detection information of the previous process at the same time. In this way, the RFID reader reads the information in a continuous cumulative state. If a fault occurs, it can be judged that the wire harness has missed the inspection and the finished wire harness needs to be supplemented with additional inspection.

[0030] It also includes several alarms, each of which corresponds to a corresponding finished wire harness offline process, and the alarm has a matching number with the RFID card reader in the finished wire harness offline process, and all alarms are electrically connected to the server.

[0031] In this solution, each alarm corresponds to a corresponding finished wire harness offline process, so that the finished wire harness offline process corresponds to the alarm one by one, and there is a matching number between the RFID reader and the alarm in the finished wire harness offline process; in this way, when a fault occurs in the finished wire harness offline process, the RFID reader of the finished wire harness offline process fails to read the RFID tag information in the finished wire harness, and the RFID reader feeds back a no-read signal to the server. At this time, the server knows which finished wire harness offline process has not been detected based on the RFID reader. At this time, the alarm on the finished wire harness offline process will be activated to sound an alarm, so that the undetected finished wire harness offline process can be quickly located, and the finished wire harness can be supplemented with detection.

[0032] Secondly, the RFID tag is attached to the tail of the finished wire harness along the transmission direction of the offline process. This design can meet the requirements of when the finished wire harness is tested along the transmission direction of the offline process, after the finished wire harness is tested, the RFID tag at the tail of the finished wire harness is read by the RFID card reader in the offline process of the finished wire harness. At the same time, the server will add the detection information to the RFID tag and store it in the server.

[0033] The alarm is fixed at the head of the finished wire harness offline process along its transmission direction. With this design, when the RFID card reader is faulty, the server activates the alarm to sound an alarm. The alarm is fixed at the head of the finished wire harness offline process along its transmission direction, so that the alarm sound or alarm light can better alert the staff at the back end of the finished wire harness offline process.

[0034] The utility model constructs a radio frequency traceability system between the RFID tags on the finished wire harness each time it is manufactured and several RFID readers in the off-line process of the finished wire harness. In the production process of the wire harness assembly line, data is stored for each process to form a traceability query traceability system. After the wire harness product leaves the factory, the data of the wire harness product is traced and queried in time to determine whether the wire harness product has completed all processes.
