Double-Headed Sensor Increases Gap Penetration

ZEISS 3D sensors combine 2D contour measurement using the multiple line triangulation principle enabling high precision, high-speed inspection of complex geometric characteristics in vehicle body construction.

The ZEISS AIMax twin sensor is used to capture the geometric dimensions of the gap and the flush on metal and painted surfaces. The use of a double-headed sensor increases gap penetration.

The double-head sensors ZEISS AIMax twin and ZEISS AIMax twin UV inspect gap and flush values on vehicles during manufacture and are indispensable management tools fo controlling production processes. The enhanced ZEISS product portfolio and the extension of the proven AIMax family of sensors ensure closed-loop in-line process control.

The ZEISS AIMax twin UV measures the geometric gap on various surfaces. This sensor takes the capture of gap and flush values one step further: in addition to painted and metal surfaces, it is now possible to obtain these values on non-cooperative and transparent surfaces, e.g. glass and plastics.

ZEISS AIMax twin UV can both be used as part of the 100% inspection for flush and gap measurements – and in any type of production facility: from car body construction all the way to final assembly of the finished vehicle. Early detection of gap and flush values can prevent the need for extensive and costly subsequent reworking. Cross-facility, in-line performance tests not only have a positive impact on the subsequent tightness of the vehicle and ensure correct door closing forces, but also enhance the customer‘s driving experience by reducing driving noise. Various factors which can influence the dimensional stability of the hang-on parts, such as temperature fluctuations, tension release, vibrations, mechanical and chemical processes, result in process influences throughout the entire production process. 100% inspection of the gap and flush values therefore is indispensable for the control of production processes.

Due to its doublehead sensor technology, the ZEISS AIMax can measure and evaluate gap values geometrically from two directions. The result is an even more precise inspection with more information whch can be restored to the process. A large number of gap and flush lines on the vehicle are located in relevant visual zones and are often created by adjacent components made of various surface materials, e.g. glass, plastic, chrome and rubber seals. For this reason, the inspection of these customer-relevant gap and flush values has increasingly come to the fore. The measurement and inspection of various non-cooperative materials has been mastered by the ZEISS AIMax twin UV sensor.
