Reading of the board labeling and assignment of the press parameters

Combination of board data with batch data

The blanks coming from the coil system are temporarily stored before further processing. The data collected by evoTrQ provide information on which stack the individual blanks are on and whether changes in material properties have taken place within a stack, e.g. due to coil changes.

Equipping the press

Process steps such as equipping the forming press with blanks marked by evoTrQ are reported to the system as events and can be called up again later.

Camera Station

The camera station reads codes lasered onto the circuit boards again, so that evoTrQ can display data generated in the cutting press via the evoTrQ DASHboard. Both operating personnel and systems connected to evoTrQ can make decisions and make necessary adjustments.

Brush system, post-oiler

The spot lubrication can be controlled with the information on the board, e.g. about the condition of the oiling. It is also possible to determine the position of the board on the conveyor and to inform the spot lubrication of the displacement of the board. This ensures that if the plate is shifted, the oil actually hits the point where it is to be re-oiled.

Drawing level parameters

evoTrQ records the settings that tools work with during processing - such as the configuration of drawing stages and rams. In addition to the material properties of the component, the system parameters of the individual processing steps can always be traced.

Correlations - fault and cause

Crack detection

There are different methods for crack detection at the various OEMs. Cameras are typically used, as well as different types of lighting. The transmitted data are also taken over and assigned to the board. In the meantime there is also a tool from the evoTrQ kit called evoVIU, which can be used for local crack detection.

Storage of the boards

The finished parts are stacked on the transport container

The operator or a robot stack the pressed parts in a box. A camera system reads both the number on the circuit board and the number of the box. This ensures that the parts can be tracked further. The higher-level logistics system receives information from evoTrQ in which box which pressed parts are and of course which properties they have. With a handheld camera system, the operator can read the number of the box and have the content displayed.

Storage and distribution

Components tracked via evoTrQ are now enriched with a large amount of information. If deficiencies are found in the following steps, material properties and processing steps can be traced in their respective parameterization and assigned to the stored components. This process knowledge enables detailed error analyzes and helps to identify affected components in the warehouse. With a hand-held camera, every employee can see the number of the Read the transport container and immediately know which material is stored in the box with which data.

Quality of the input material

Coil data

In the ideal case, the already "Smart Coil" is delivered with the information provided from production, such as width, thickness, material properties, roughness, etc. The supplier has already saved the data in a cloud. There they can be called up to the meter using a label or code on the coil. The code is read with a camera and added to the system. This can also be done manually. It should be noted that the code applied in the center and with ink on the coil is washed off and is not available on every board after cutting. Please also note that if, for example, two boards are cut in parallel, not every board contains the code.

Inline measurement of further material and process parameters

Tensile strength, surface roughness, strip thickness measurement

If these values are not available from the manufacturer when the coils are delivered, appropriate sensors or devices to record them can be attached to the system. With the evoTrQ system, these are picked up, integrated, visualized and made available for evaluation. The measuring systems can also be delivered turnkey by evopro.

Oil layer thickness measurement

To ensure production accuracy, it is necessary to have the required oil film in the right places during the pressing process. This requires precise and uniform oil film thicknesses on the blanks, which can be recorded using measuring methods and also assigned to the coil. The oil layer thickness cannot be supplied with the coil as there is a redistribution during winding and storage. Here, too, Evopro has the know-how for the turnkey integration of a measuring device.

Straightening machine parameters

Here, various values for equalizing and aligning the various coils are generated and recorded by the machine. By adopting these values in the evoTrQ system, these quality parameters are attached to the respective circuit board.

Labeling of the board

Laser marking

The circuit boards are marked with the help of a laser while the material is running. As soon as this has been done, the raw material data (coil), the parameters collected from the previous process steps and the data recorded from the following process steps can be assigned to each blank. From here on, each board is "SMART" and from this point on is equipped with unique (quality) features. 4 laser heads can mark at the same time. The depth of the font is 10 μm.

Contour measurement of blanks

In order to avoid faulty production or rejects, various contour features can be recorded at this point with the help of an optical contour measurement directly after the blanking process. This can be the defined number, the relative position, the dimension as well as internal and external features as well as the shape and position of the components. Depending on the requirements and characteristics, these values are recorded and processed.
