Spring Appearance Defect Inspection Program-Plastic Industry-Specialized in visual imaging solutions_Non-standard optical customization-Dongguan Chuangshi Automation Technology Co., Ltd

Industry background

In modern industry, the spring as a common mechanical parts, in all kinds of equipment and mechanical products are widely used to buffer pressure, transfer force, improve the stability and safety of equipment operation. In actual use, the spring is in the long-term uneven force size, the force direction of the changing working conditions. In the production process, if there is poor winding, under stress corrosion, the spring surface is prone to fatigue cracks, affecting production safety. Take the plastic industry as an example, the requirement to assemble springs on plastic parts, how to test the appearance of the spring without damaging the sample to ensure that the spring is wound correctly? The manufacturer chose to adopt Trunsign's automated spring appearance inspection program!

Industry pain points

1, need to ∅ 20mm size of the outer ring of the sample spring appearance inspection, to determine whether there is a bad winding phenomenon;

2, metal wire surface reflections, spring winding irregularities, the rotation angle is not up to standard or did not reach the camera shooting position and other factors will cause the detection results deviation;

3、Spring winding end through the stress tear off, easy to retraction phenomenon. Due to the instability of the equipment, the angle of retraction is not consistent each time, and it is easy to have height deviation in the field of view, causing misjudgment to the camera.

Inspection Program

After receiving the customer's demand, Chuangshi Automation sent a team of engineers to conduct an on-site inspection, and based on the results of the research, recommended the customer to adopt Trunsign Automation's spring appearance inspection program.

In Terms of Software Selection:

Adopting Chuangshi professional software CS-Vison 2.0 to recognize the detection algorithm module, with hundreds of built-in algorithms, the inspection can be easily completed with simple settings. And in the detection process, the software automatically records the statistical fluctuations in the value of each test item, and the number of qualified and unqualified changes, which is convenient for enterprises to analyze the quality data and statistics. Support system intelligent self-test, remote troubleshooting and online software upgrades, to achieve rapid and accurate detection of spring appearance.

In the Choice of Hardware:

Adopt black and white camera with light source module that can achieve multi-view imaging effect. Realize a single imaging camera can shoot samples 360 degrees of the effect, in different viewpoints to highlight the spring winding defects. Compatible with different color samples, to avoid the single-station multiple testing or multi-station detection of cumbersome, improve detection efficiency and save project costs.

the appropriate light source, to achieve a high inspection rate, to help companies save manpower and significantly increase production speed. In the plastic industry, for example, the production efficiency compared to the previous has been significantly improved, helping enterprises to achieve automation and intelligent production.

Advantages of the plan

To address the problem of inspecting the appearance of the outer spring of plastic parts, by adding Chuangshi Automation spring inspection solution to the automated production line, it is possible to realize a batch full inspection of the production line without damaging the samples. Efficient and easy-to-use algorithm software with the appropriate light source, to achieve a high inspection rate, to help companies save manpower and significantly increase production speed. Take the plastics industry as an example, the production efficiency has been significantly improved compared to the previous one, helping enterprises to save labor and significantly increase production speed.

Before the significant increase in production efficiency, helping enterprises to achieve automation and intelligent production.
