Automated CCD Vision Inspection for Automotive Oil Temperature Sensors

Automotive oil temperature sensor CCD vision inspection machine with multi-position fixtures, automated transfer, controlled lighting and multi-view image analysis.

This project features a standalone CCD vision inspection machine developed for automotive oil temperature sensors. The system combines dedicated multi-position fixtures, automated transfer mechanisms, CCD cameras, controlled illumination, and vision inspection software within one enclosed inspection cell. Multiple sensor assemblies can be positioned in parallel and moved through defined optical inspection stations, where the camera system captures and evaluates selected product features.

The CR-726A shown in the video operates as an independent inspection station rather than as a machine mechanically linked to upstream equipment. Sensor assemblies are supplied to the unit separately, processed through the internal handling and vision sequence, and then removed for the next production step.

Multi-Position Loading for Sensor Assemblies

The automotive oil temperature sensors shown in the project are long cable-type assemblies. Multiple products are arranged side by side in dedicated fixtures so that each sensor remains separated and aligned during handling.

The fixture provides repeatable reference positions for the vision system. This is important because machine-vision inspection depends on a stable relationship between the component, camera, lighting, and inspection area. By keeping each sensor in a defined position, the machine can repeatedly present the required product features to the camera under consistent conditions.

Instead of manually presenting one sensor at a time to an inspection camera, several sensors can be arranged within the working area and processed through the automated sequence. The material flow begins with sensor loading, fixture positioning, automated transfer, and CCD inspection.

Automated Transfer Between Vision Inspection Positions

Several linear handling mechanisms are integrated into the machine. During operation, the transfer unit grips or supports a group of sensors and moves them between the loading area and the different vision inspection positions.

The video shows the sensor assemblies being held in parallel while the handling mechanism moves them across the machine. Because the products have long flexible leads, the fixture and transfer system maintain separation between adjacent sensors while their inspection areas are positioned inside the camera stations.

The sequence follows a repeatable pattern: pick the sensor group, move to the inspection position, align the target area, capture the image, and then continue to the next inspection position.

CCD Cameras with Controlled Lighting

The machine contains dedicated camera and lighting assemblies for visual inspection. Controlled illumination is used around the inspection area so that the CCD camera receives a more consistent image of the component surface and geometry. This reduces the influence of changing ambient factory lighting on the inspection result.

Different optical assemblies are visible inside the machine, indicating that the sensor is inspected from more than one defined viewing position. Rather than relying on a single general-purpose image, the system presents specific sections of the product to the corresponding camera and illumination arrangement.

Multiple Inspection Images on the Vision Interface

The machine monitor displays several captured images simultaneously. Each inspection window corresponds to a defined visual inspection area. The software processes the captured image and compares the detected product features with programmed inspection criteria.

The interface also displays inspection status information for the individual image positions, allowing the result of each visual check to be reviewed directly on the machine. The inspection sequence therefore follows a structured process: position the product, illuminate the target area, capture the CCD image, analyze the image, and generate the inspection result.

Multi-View Inspection of Sensor Features

An automotive oil temperature sensor is not a single rigid component. The finished assembly includes the sensing section together with the connected lead or cable structure, and different areas may require visual verification during production.

The CR-726A uses several optical positions to capture defined views of the sensor assemblies. By moving the products between these positions, the system can inspect different areas without requiring an operator to manually rotate or reposition every component.

The video shows multiple product images on the vision interface, confirming that the inspection process is based on several defined visual checks rather than a single camera snapshot.

Standalone Vision Inspection Station

The machine is configured as a standalone vision inspection station. It is not mechanically connected to an upstream production machine in the configuration shown in the video. Products are supplied to the inspection equipment separately and then processed through the internal automated handling and vision sequence.

This arrangement allows the inspection process to operate independently from the cycle of the upstream equipment. The station performs product positioning, automated handling, CCD image acquisition, image analysis, and inspection result generation within its own enclosed cell.

Automated Visual Inspection in Oil Temperature Sensor Production

The complete inspection process combines multi-position sensor loading, automated product transfer, controlled positioning, CCD image capture, multi-view image analysis, and inspection result generation.

For automotive oil temperature sensor manufacturing, this replaces repeated manual visual checks with a standardized machine-vision process. The fixtures maintain sensor positioning, the transfer mechanisms move the products through the optical stations, the controlled lighting provides stable imaging conditions, and the CCD vision software evaluates the captured features according to predefined inspection criteria.

Together with electrical testing equipment used elsewhere in the production process, the CR-726A provides an additional automated quality-control step focused on the visual characteristics of the automotive oil temperature sensor assembly.
