Inspection principle

In terms of its detection nature and application scope, machine vision industrial inspection systems are divided into two categories: quantitative and qualitative inspections, each of which is divided into different subcategories. Machine vision is very active in various application fields of industrial online inspection, such as: visual inspection of printed circuit boards, automatic flaw detection of steel plate surfaces, measurement of parallelism and perpendicularity of large workpieces, detection of container volume or impurities, automatic identification and classification of mechanical parts and Geometry measurement, etc.

In addition, machine vision systems can be effectively implemented in many situations that are difficult to detect by other methods. The application of machine vision is increasingly replacing people to complete many tasks, which undoubtedly improves the level of production automation and the intelligence level of inspection systems to a large extent.

Applications of machine vision

There are speedometers, water temperature gauges, gasoline gauges, ammeters, signal alarm lights, etc. installed on the dashboard of the car. The production batch is large, and a final quality inspection is required before leaving the factory. The testing items include: testing the indication errors of five instrument pointers including the speedometer; testing whether 24 signal alarm lights and several lighting 9 lights are damaged or missing.

Generally, manual visual inspection is used for inspection, which has large errors and poor reliability, and cannot meet the needs of automated production. The intelligent integrated test system based on machine vision has changed the status quo, realized the intelligent, fully automatic, high-precision, and rapid quality inspection of the instrument panel assembly, overcome various errors caused by manual inspection, and greatly improved the inspection process. efficiency.

The laser is used as the light source, and the stray light around the laser beam is filtered through the pinhole filter. The beam expander and collimator make the laser beam into parallel light and uniformly illuminate the surface of the metal plate to be inspected at an incident angle of 45 degrees. The metal plate is placed on the inspection table. The inspection table can move in the three directions of X, Y and Z. The camera adopts TCD142D type 2048 line Chen CCD, and the lens adopts ordinary camera lens.

The CCD interface circuit adopts the single-chip microcomputer system. The host PC mainly completes image preprocessing, classification of defects or depth calculation of scratches, etc., and can display the images of detected defects or scratches on the monitor. Two-way communication is carried out between the CCD interface circuit and the PC through the RS-232 port, combined with the asynchronous A/D conversion method to form human-computer interactive data collection and processing.

System advantages

The company has a complete technical service team and rapid response mechanism, and has dedicated service specialists for each customer, who can receive technical consultation and fault reports from customers at any time. And to ensure rapid response to customer emergencies, to ensure that customers receive satisfactory service.During the epidemic or due to special reasons, when after-sales engineers are unable to reach the site, the service center can remotely adjust customer equipment for troubleshooting and technical consultation.

After the equipment arrives at the customer site, the after-sales engineer arrives in time to carry out equipment installation, commissioning, and operation training. The product quality of the whole machine is traceable, and the quality warranty period is 1 year from the date of acceptance. In the event of non-human faults during the warranty period, after-sales engineers will quickly arrive at the site or provide remote guidance for free maintenance.
