Full-Link Application: Application Scenarios of Industrial Lenses In The Plastic Products Industry

Industrial lenses, with their high resolution, low distortion, and high stability, have become a driving force behind the intelligent upgrade of industrial production. The plastics products industry, which covers a wide range of applications from daily necessities to precision components, places extremely high demands on dimensional accuracy, surface quality, and defect control during production, creating a significant demand for industrial lenses.

In this article, we will learn about the full-link application scenarios of industrial lenses in the plastic products industry.

1.Real-time monitoring of injection molding process

During the injection molding process of plastic products, industrial cameras can monitor the mold status and molding process in real time to ensure production efficiency and product quality.

For example, scanning the mold surface with a high-resolution industrial camera before injection can identify subtle scratches or residues to prevent them from being transferred to the final product. This mold inspection can significantly reduce the scrap rate caused by mold damage.

In addition, infrared industrial lenses combined with thermal imaging technology can monitor the temperature distribution and flow state of the melt during the injection molding process in real time, optimize the injection pressure and speed parameters, and reduce problems such as shrinkage and warping caused by uneven cooling of the melt.

2.Appearance defect detection

Industrial lenses can be used for surface inspection and quality control of plastic products. Through their high-resolution imaging capabilities, they can detect defects, bubbles, foreign matter, scratches, and other issues on the surface of plastic parts, ensuring that the surface of plastic products is smooth and uniform, meeting both aesthetic and functional requirements.

In addition to surface defect detection, industrial lenses can also detect the surface quality of printing or spraying. For example, color industrial lenses can check the color accuracy of label printing and the uniformity of UV spraying to ensure that logos, barcodes, etc. are clear and free of ghosting.

3.Critical dimension measurement

Industrial lenses can also accurately measure the length, width, thickness, and other dimensions of plastic parts to ensure they meet design requirements. Through the machine vision system, industrial lenses can capture images of parts and combine them with image processing technology to perform operations such as size measurement and shape detection.

For example, a bilateral telecentric lens can measure the module and addendum height of plastic gears or the hole spacing of a mobile phone casing. A laser profilometer combined with an industrial lens can reconstruct the curvature and flatness of plastic parts to verify conformance to CAD models.

4.Assembly and functional testing

Industrial lenses also play a vital role in the automated assembly of plastic products. For example, during the assembly of plastic parts, industrial lenses can help robots precisely locate parts and achieve accurate assembly. This application not only improves production efficiency but also reduces labor costs.

Industrial lenses are also used in functional testing of plastic products. For example, in airtightness testing, high-speed industrial lenses are used to observe the micron-level deformation of plastic housings after pressurization to infer sealing performance.

5.Packaging integrity testing

Industrial lenses can be used to inspect the packaging process of plastic products to ensure that the product packaging is intact and improve the quality of the product appearance.

For example, they can be used to check the integrity of the sealing ring of plastic bottle caps and the quality of the blister formation of blister packs. Compared with manual inspection, using industrial lens vision system to inspect packaging greatly improves efficiency.

6.Material and process optimization

Industrial lenses can also detect the distribution of additives in plastic products and optimize materials and processes. For example, multispectral industrial lenses can analyze the uniformity of glass and carbon fiber distribution in plastic slices to optimize the mixing process.

In addition, industrial lenses can be used to perform aging and durability tests on plastic products. By tracking the expansion of microscopic cracks in plastic parts under high temperature and ultraviolet rays over a long period of time, the service life of the product can be predicted.

In short, compared to traditional inspection methods, using industrial lenses to monitor and control the quality of plastic products throughout their entire process, including materials, appearance, dimensions, and assembly, not only improves inspection efficiency but also increases accuracy, reduces missed inspection rates, and significantly enhances product quality control. Therefore, industrial lenses have become an indispensable tool in the plastic products industry.

The Specific Application of IR Corrected Lenses In Night Photography

图片
A n   IR corrected  lens is a specially designed lens that can capture high-quality photos or videos both during the day and at night. IR corrected  lenses usually have a larger aperture and excellent low-light performance, which can capture detailed images in low-light conditions and also perform well in night shooting. IR corrected  lenses can capture more details and colors at night. The specific applications in night photography are mainly manifested in the following aspects: 1. Night security monitoring In the field of security monitoring, night monitoring has always been a key issue. The IR corrected  lens can automatically switch to black and white mode and use an infrared fill light to provide good night monitoring effects and achieve clear observation of objects within the monitoring range. 2. Night c ity p hotography In the city at night, the IR corrected  lens can help capture scenes such as high-rise buildings, traffic on busy streets, lights a...
