Vision systems in the automotive industry

In the automotive industry, where even minor faults can lead to major accidents, the demand for quality and precision is high. To better meet this demand, inspection benchmarks are constantly being upgraded. It is known that the number of parts in a car will exceed 30,000 if you count the tiny bolts, and it will increase as versatility progresses. Fully inspecting and accurately managing these components is no easy task.

Relative to OEMs, in the event of a recall, it is important to develop and quickly delineate the scope of the impact study and categorize the problem, otherwise it will cause a huge loss, and even damage the image of the corporate brand culture. Especially in China in recent years, the government management can develop the country introduced the automobile company recycling law, airbags, chlorofluorocarbons and other recycling cycle has also become the obligation of manufacturers. For this reason, in addition to the design and manufacture of parts and the assembly of the entire vehicle,vision inspection systems it has become an urgent requirement to ensure traceability from the time of preparation and overhaul to the time of scrapping.

The demand for information databases dominated by test results is increasing year by year, and visualization systems are receiving more and more attention as one of the means to do so. The vision system is expected to replace the previous visual and experience-based inspection process for high efficiency, cost reduction and accuracy.

Several aspects of vision system inspection of automotive consulting services are briefly described:.

1. Checking for button assembly errors on the operator panel, LCD monitor, etc.

2. Detection of poor motor wire bundling (bundling) , poor soldering

3. Measurement and color can be identified through the outer diameter, detection of fuel injectors in the assembly of various types of working parts of the error

4. Detecting subtle shape differences in seat belt hardware, and identifying varieties.

5. Identify differences in the diameter and number of teeth of gears and implement variety identification.

6. Differentiate between varieties by measuring the full length and diameter of connecting rods

7. Checks the amount of grease applied.

8. In a process of hot forging, we confirm that the workpieces in the metal mold are mounted in different positions.

9. Checking the shape of the wheel to prevent mixing of different varieties.

10. Preventing mixing of different varieties by detecting the difference in tire color markings.

11. Detecting liquid sealants applied to various components such as engines, gasoline engines, oil sumps, etc.

12. Detecting holes on the surface when the camshaft is rotating.

13. Detect the appearance of bad design of equipment bearings

14. Checking the chip in the piston groove

15. Inspection of defective characters displayed on a monitor

16.Detecting defects in rubber molded parts

17.Implementation of LED lighting inspection for tail lights, high beams, etc.

18.Inspection of steel balls falling out of equipment bearings

19.Inspect O-rings for burrs and defects

20. Use vision system to detect the position and angle of measuring pointer

21. Measure the closure of piston ring

22. Inspect the welding position before bending.

23. Measurement of the shape of the sealing material to check the amount of coating possible.

And so on and so forth.
