Description

TECHNICAL FIELD

[0001] The utility model relates to a wiring auxiliary device technical field especially relates to a harness assembly intelligent mistake proofing wiring control device. BACKGROUND

[0002] The current commonly used hole position installation mode in the harness industry is as follows: a process engineer splits the whole wire, combines quality mistake proofing control requirements (same color wires are not installed at the same station) and process capacity beat balancing, allocates each single wire hole position installation (according to the product, the number of single wires is dozens to hundreds) to a first online turnover station or a second pre-installation auxiliary station which constitutes a continuous assembly line operation, compiles and continuously optimizes the station process operation instruction book, and each station operator takes out the cut length and the lead after the terminal from the warehouse according to the material taking requirement of the operation instruction book, and places them into the corresponding storage box, and according to the installation requirement of the operation instruction book, inserts the two ends or one end of the lead into the corresponding sheath hole position, and each station operator forms a flow type cooperative assembly line to complete the hole position installation of the lead (according to the product, the number of leads is several to hundreds) in the sheath (according to the product, the number of sheaths is several to dozens), and the finished product is detected by an electrical function conduction test table before leaving the factory to detect whether the hole position installation is wrong.

[0003] Due to the increase of intelligent development electrical function and cost control factors, the sheath is designed to be compatible, the number of holes and sheaths is increasing, the interval between the holes is smaller and smaller, and due to the large number of leads, the color variety of the leads is insufficient (only more than 10 kinds), so it is impossible to realize the mistake proofing control requirement that there is no same color wire at the same station, therefore, in actual operation, even if the operator has been trained for a long time, the operator is prone to eye fatigue, misreading of position, and wrong wire, leading to frequent assembly errors of lead insertion into the wrong sheath hole position without knowing it.

[0004] In the past 30 years of rapid development of the automobile industry, this process mode has been used and has not been substantially changed, and the manufacturing management problem in the harness industry has not been effectively solved, and the hole position assembly error has been named as an "industry common disease".

[0044] In order to enable the personnel in the art to better understand the utility model scheme, the technical scheme in the utility model embodiments will be clearly and completely described below in combination with the drawings in the utility model embodiments. Unless otherwise defined, all the technical and scientific terms used in the present document are the same as the meanings commonly understood by the personnel in the technical field to which the utility model belongs. The terms used in the specification of the utility model in the present document are only for the purpose of describing the specific embodiments and are not intended to limit the utility model.

[0045] In the present document, the phrase "embodiment" means that the specific features, structures or characteristics described in combination with the embodiment can be contained in at least one embodiment of the utility model. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment and is not an independent or alternative embodiment that is not mutually exclusive with other embodiments. The skilled person in the art explicitly and implicitly understands that the embodiments described in the present document can be combined with other embodiments.

[0046] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 8 , the utility model embodiment provides a kind of wire harness assembly intelligent mistake-proof wiring control device, it include: main controller and sub-controller 10, the sub-controller 10 is not less than two, each sub-controller 10 is connected with the main controller by data bus, each sub-controller 10 is equipped with wire detection interface and pilot lamp 101, one wire detection interface is equipped with multiple wiring sockets 102, the main controller is used to carry out lighting or extinguishing control to pilot lamp 101, to carry out wire insertion indication to the wiring socket 102 on two wire detection interfaces.

[0047] Specifically, as Figure 1As shown in the figure, the 485 main controller is externally connected with a plurality of sub-controllers, and the number of the sub-controllers depends on the number of the connectors 20 of the wire harness, wherein the maximum pin PIN of each connector 20 can be 47. The specific sending instruction of the 485 main controller can be designed according to the specific requirements of the customer for wiring; during the wiring process of the connector 20, one end of the connecting wire 30 needs to be inserted into one port of one connector 20; and the other end of the connecting wire 30 needs to be inserted into one port of another connector 20. Since the ports of the connector 20 are relatively more, it is easy to cause the port to be inserted incorrectly during the insertion. In order to insert the connecting wire 30 into the corresponding port of the connector 20 during the wiring, the main controller can send a corresponding indication signal to the sub-controller 10 during the wiring, and the sub-controller 10 can light up the indicator lamp 101 corresponding to the port of the wire detection interface. Since the wiring jack 102 of the wire detection interface, the port of the connector 20 and the indicator lamp 101 correspond to each other; for example, in an example of the utility model, one of the indicator lamps 101 is arranged at the corresponding position of the wiring jack 102. In this way, when the corresponding indicator lamp 101 corresponding to the wiring jack 102 is lighted up, the connecting wire 30 can be inserted into the corresponding port of the connector 20. As shown in the figure, Figure 2 When the lamps at the corresponding positions of the two sub-controllers 10 are lighted up, one connecting wire 30 can be inserted into the corresponding wiring jack 102. Since the connector 20 is also located at the position of the wire detection interface, the connecting wire 30 can be inserted into the corresponding position of the connector 20, so that the connecting wire 30 can be accurately connected to the two connectors 20, thereby preventing the connecting wire 30 from being inserted into the wrong position and improving the accuracy of the insertion of the connecting wire 30 into the connector 20.

[0048] Referring to Figure 3 , the sub-controller 10 comprises a control board circuit and a lamp board circuit, the control board circuit is in communication connection with the main controller to receive the control signal of the main controller; as Figure 3 shown in the figure, each sub-controller 10 is in communication connection with the main controller through a data bus, so as to receive the control signal issued by the main controller; the control board circuit can control the lighting or extinguishing of the indicator lamp 101 on the lamp board circuit according to the received control signal. The lamp board circuit comprises an indicator lamp 101 circuit and a wire detection interface circuit, the indicator lamp 101 circuit comprises the indicator lamp 101, the wire detection interface circuit comprises the wire detection interface, and the lamp board circuit is connected with the control board circuit to control the lighting of the indicator lamp 101 under the control of the control board circuit.

[0049] Referring to Figure 2 , Figure 3 and Figure 8The main controller and / or the control board circuit is further configured to control or detect signals of the wire detection interface to detect the wire insertion state of each wire jack 102 on the two wire detection interfaces. As shown in Figure 2 , Figure 3 and Figure 8 When the two ends of the connecting wire 30 are inserted into the two sub-controllers 10, the corresponding wire detection interface of the sub-controller 10 is in an on state. In order to detect whether the connecting wire 30 has been correctly connected, the control board circuit of one of the sub-controllers 10 can output a high level signal through the corresponding wire jack 102 (the corresponding pin PIN of the connector 20) of the connecting wire 30, and the control board circuit of the other sub-controller 10 can detect whether the corresponding wire jack 102 (the corresponding pin PIN of the connector 20) of the connecting wire 30 is a high level signal; in this way, it can be determined whether the connecting wire 30 is inserted into the correct port. For example, when it is necessary to detect whether PIN1 of the connector 201 is inserted into PIN2 of the connector 202 through the connecting wire 30. By controlling the PIN1 detection port of the connector 201 to pull high, it is detected whether there is a high level signal from the PIN2 input port of the connector 202; if there is, it indicates that the wire is inserted correctly. Then, the control board circuit can send the state of the connecting wire 30 to the main controller, and wait for the host to read the state of the wire harness. When the wire insertion jack is inserted incorrectly, an alarm prompt can be given to correct the error.

Since the external interface of the control board circuit is relatively small, when the number of indicator lamps 101 and wire jacks 102 is relatively large, the input and output interfaces IO of the interface expansion circuit can not meet the application requirements. Therefore, the expansion of the input and output interfaces IO can be realized through the interface expansion circuit to meet the connection of a plurality of indicator lamps 101 and wire jacks 102. As shown in Figure 8As shown in the figure, the interface expansion circuit can include two expansion controllers, expansion controller U2 and expansion controller U4.
