VisionUnit allows Variable Focus Adjustment in the Tightest of Spaces

Cognex In-Sight based VisionUnits by senswork

Camera systems with telecentric lenses and the corresponding working distance are often too long to be integrated into a machine without space problems. No problem with the Cognex In-Sight based VisionUnit from senswork.

VisionModule from senswork checks correct feeding of microchips in fully automatic system

Ensuring the correct feeding of microchips

Applications in the semiconductor industry require both high-precision, leading-edge technologies and reliable performance characteristics in cleanroom and control test environments. One of the largest manufacturers of semiconductor device handling systems relies on a specially developed VisionUnit from senswork to ensure chip positioning for very small chip sizes with extremely small dimensions.

Shape-from-Shading system inspects graphite surfaces for damage

Surface Inspection of Graphite

Today, die-pressed carbons and graphites are used in large quantities to manufacture a wide variety of subcomponents for the automotive industry, such as fuel and water pumps. To ensure that the products leave the production line free of defects, senswork has developed a fully automated system for the quality assurance of such components together with a mechanical engineering company from Rosenheim.

The VisionUnit from senswork enables a semi-automatic measurement of connector assemblies

2D-Measuring System for Connector Assemblies

The gap between contact surfaces plays a major role in connector assemblies. The distance between the individual contact surfaces is measured to an accuracy of 0.01 mm. For this purpose, the test parts are brought into the VisionUnit. The plug is clamped via a clamping mechanism and light diffusers are simultaneously delivered to the assembly, which display the gap between the contact surfaces in high contrast. A high-resolution camera in conjunction with telecentric optics then measures the gap between the individual contacts.

Turnkey inspection device with an automatic focusing device

Pin Inspection of Fakra Connector Assemblies with Press Fits

The testing device, which is 100% manufactured by senswork, enables the measurement of Fakra plug assemblies with an accuracy range of ± 0.02 mm. Both the Fakra interface side and the PCB side with press fits are tested with this device. An automatic focusing device ensures that the pins relate to the reference feature with constant image quality. The system is calibrated by a checkerboard calibration with high-precision calibration targets.

Dual Camera System Detects Nest Numbers on Miniature Components

OCR System for Turbocharger Guide Vanes

A dual camera system with mirror deflection enables the reading of part numbers on so-called turbocharger guide vanes by means of OCR. For this purpose, two Cognex In-Sight 8000 smart camera systems were integrated into a senswork VisionUnit with mirror deflection.

Camera system with variable camera adjustment insepcts the Fakra connector assembly

Turnkey Manual Testing Station

The turnkey test system consisting of a camera for the PCB side and a camera for the interface side tests a wide variety of Fakra plug assemblies. This is made possible by an adjustable viewing direction of the camera on the interface side and a well thought-out interchangeable set of partial exposures. Good parts are marked with a needle head that is integrated directly into the part receptacles.

Quality Inspection in the Manufacture of Reversing Sensors

Inspection System for Reversing

For a French automotive supplier, senswork developed and implemented optical control modules for the quality inspection of automotive reversing sensors. Different sensor types are processed in one machine, then packed and stacked in different trays. The modular machine consists of four assembled modules connected by a common control system. A total of seven camera systems are used for optical inspection and defect detection.

When the resolution alone is no longer enough ...

Manual Test Station with 3-Axis System for Connector Assemblies

With 18 images in different positions and focal planes on the component, our camera system checks a connector assembly on the front and back. With a resolution of 8 µm / pixel and the specially developed stitching tool, the images are joined together and combined into one overall image.

VisionUnit with automatic focus adjustment checks USB plugs

USB Connector Inspection on Multiple Focal Planes

With USB connectors there are different contact surfaces on different Z-planes. In order to ensure a sharp view of the contact quality even at high resolution, this VisionUnit records several images on different focal planes in the shortest possible time. The characteristics are calculated across screens in the test program.

VisionUnit inspects connector assemblies in a test machine

Smart Camera with Mirror Deflection

With another VisionUnit from senswork with mirror deflection and manual focus adjustment, hundreds of connector assemblies are fully tested every day in an automatic testing machine from Adaptronic. The additional lighting ensures the best lighting conditions for the high-contrast representation of the test features.

Maximum image sharpness for a wide variety of component types

VisionUnit with Manual or Automatic Focus Adjustment

In order to obtain maximum flexibility with regard to the most varied connector types for manual connector inspection at a manual test station, we use our powerful VisionUnits from senswork with variable focus adjustment. The focus variation is made possible via a 30 mm servo axis, which can be controlled either via a PLC or directly via the camera program.

Measurement of the inner conductor tip deflection of coaxial cables

New 3D Method for Inspecting Coaxial Cables

In high-frequency technology, the quality of the installed coaxial cables, especially in the connection area of the cables, plays a major role in the subsequent signal quality. The measuring system developed by senswork records the inner conductor tip three-dimensionally, and is thus able to precisely measure the spatial deflection of the tip as well as the protrusion from the outer conductor shield.

Connector Inspection with a Mirror and Prism System

Inspection of Cut Contacts on a Connector Assembly

This double-head inspection system checks cutting contacts from two directions at the same time by means of cleverly deflected beam paths. The beam path is deflected in such a way that both the interlacing of the contact elements with one another and the gap size can be detected at the same time. A 3D portal system positions this VisionUnit above the contact elements. This VisionUnit saves a complex and wear-prone mechanical test.
