Everything You Should Know about Automotive Appearance Inspection
Over the past few years, the automotive sector has experienced rapid growth and development, with increasing numbers of new vehicles being designed and manufactured globally. This worldwide spike can be linked to technological advancements, varying consumer preferences, and the need for more sustainable transportation solutions. Around 80 million automobiles were produced worldwide in 2021, a rise of three percent from the previous year; increased production means that the automotive industry is on the mend following the rough years of 2019 and 2020.
Considering the boosting market, here we will discuss the challenges associated with the automotive inspection of a car’s appearance and how machine vision products, including visual sensors, can help inspect in this regard. So, let’s get started.
Challenges of Automotive Appearance Inspection
The following are the challenges associated with automotive appearance inspection. In essence, these problems highlight the significance of adding visual sensors to inspect car appearance.
The high volume of vehicles produced in the automotive industry presents a significant challenge for appearance inspection. With thousands of automobiles manufactured daily, inspectors must examine each quickly and accurately while ensuring they meet the desired quality standards. As a result, the sheer number of vehicles that must be inspected can lead to potential errors, bottlenecks, or increased costs. E.g., a busy production line may struggle to maintain optimal quality control, which leads to issues like paint imperfections or body panel misalignments going unnoticed.
Achieving the required level of preciseness in the automotive inspection of a vehicle is yet another challenge. Inspectors must scrutinize every aspect of a vehicle's exterior and look for defects such as dents, scratches, uneven paint, or misaligned parts. Sometimes, these imperfections may be minuscule or barely visible and hence makes their detection even more problematic. For instance, slight color variations or subtle texture differences in the paint finish may only be apparent under specific lighting conditions, which ultimately requires inspectors to be highly attentive and knowledgeable about the specific requirements of each automobile.
Long Shutdown Time during the Inspection
The inspection process can result in long shutdown times while posing a challenge for automotive manufacturers. When vehicles are taken off the assembly line for inspection, it can interrupt the production flow and create inefficiencies. Any issues discovered during the inspection may require additional time for rework or repair, further extending the shutdown period. For example, if a vehicle's paintwork is found to have flaws, it may need to be sent back for repainting, which causes delays in the production process and potentially impacts delivery times to customers.
How SmartMoreInside's Machine Vision Products Inspect the Appearance
Here we see how machine vision products like visual sensors help inspect the car's appearance:
Machine vision products utilize visual sensors, such as industrial cameras and sensors, to inspect car frames for structural integrity and proper alignment. These devices recognize the code on the frame and capture high-resolution images of defects like cracks, corrosion, or misaligned components that can be identified through advanced image processing algorithms. E.g., a machine vision system might detect minute deformations in the frame's structure and alert quality control teams to potential safety concerns.
Visual sensors are indispensable for assessing the quality of car tires during manufacturing and usage. These sensors can capture images of tire surfaces, treads, and sidewalls and hence enable the detection of defects like uneven wear, punctures, or manufacturing inconsistencies. A common example includes using machine vision solutions to identify the presence of foreign objects embedded in the tire, which could compromise its performance and safety.
Machine vision products inspect solder joints in a car's electronic components. High-resolution cameras and advanced image processing can evaluate the quality of these joints by assessing their shape, size, and position – the process helps identify any weak or defective solder connections that could lead to electronic failure. An example of this technology in action includes examining the solder joints on a car's engine control unit, ensuring that all connections are secure and reliable.
Visual sensors and machine vision systems inspect car paint quality and consistency. These systems can detect defects, including scratches, dents, or inconsistent coloration, by capturing images of the paint surface at various angles and under different lighting conditions. For instance, a machine vision solution might identify areas of a car where paint has been applied too thinly or has not adhered well while ensuring that customers receive a flawless finish.
