July 29, 2019 - The EVT WireInspector can inspect cables and connectors for their correct contact assignment. The system can be either used for a hand-work place or for the automatic cable assembly directly online, where it is integrated in the plant.

With the “OneButton train“, the definition of the cable colors and their position can be trained with one click. Only the position of the color has to be pre-configured. This can be carried out with a ‘Golden Part’, which is a good part. On this good part all inspection windows learn automatically the color and generate a respective result protocol. The simplest result is that all cables are in the correct position. It is also possible to generate a detailed protocol, which lists the position and type of error, e.g. wrong color, cable not present, etc.

The system allows to inspect component parts in different positions and rotations, which means that it is not necessary to position the component parts in an exactly defined rotation.

There are digital I/Os (8 inputs and 8 outputs in 24 V technology) available for the implementation of the EVT WireInspector. This allows to directly control a signal lamp to indicate an error for e.g. example at a hand-work place. The connected monitor shows at the same time which cables are effected. Those cables are marked red. The correct cable assignment is shown in a reference image. The assembly worker has then the possibility to see the correct color for the incorrectly positioned cable.

The system can be pre-configured for any number of connectors. Therefore different connectors or assembly variations are easily inspected. Those can either be transferred via a master computer or a coder reader is connected to the system, which switches the inspection programs according to the code.

The adaption of the inspection for complex cables is also carried out completely graphically with a few mouse clicks. Users can ask EVT for the ideal hardware setup for the respective cable assembly.

There are different interfaces available for fully automated systems. Here are different options available, for example, the direct Profinet connection to a PLC, to which the inspection result is also delivered via Profinet. Of course also the I/O-based communication with 24 V is an option.

The EVT WireInspector is by default delivered with one camera, depending on the size of the connector, in different resolutions such as 1, 2, 5 and 6 Mpixel. Depending on the application it is also possible to use a higher resolution or more than one camera.

The smallest EVT WireInspector system is delivered with an intelligent camera head with integrated LEDs. All other systems are available with different illumination types, based on white LEDs. The illumination can be connected directly to the emSens controller, which offers the possibility to connect up to four illuminations.

The WireInspector contains also detailed statistics. The user can therefore detect, which characteristics are more often faulty than others. With this exact error analysis, the user can intervene directly into the production process.

The user has many options available for example to save the data in an SQL data base or to automatically compare the protocol of the respective connector with the master computer. The system is prepared to also read codes on the connectors, to protocol them or send them directly to the connected master computer. A 100%-retraceability can therefore be reached.
