The development status of the automotive industry
With the rapid development of the automobile industry, users have put forward higher and higher requirements on the performance, quality, model, environmental protection and economy of automobiles. This has forced automobile manufacturers to continuously adopt new materials, change new processes and Continuously improve the degree of production automation to meet this requirement, which also puts forward higher requirements for position detection sensors in the automotive production automation process. TURCK’s new generation of Uprox+ inductive sensors can meet these requirements to the utmost extent.
Breaking through tradition–the innovation of Uprox+ sensor
The Uprox+ inductive sensor adopts a patented PCB structure with multiple coils, which completely changes the epoxy core process structure of the traditional inductive sensor, making Uprox+ products have full metal detection, increased detection distance, and excellent EMC Excellent performance in terms of characteristics, pre-damping characteristics, etc., so it has a wider range of versatility, which has been concentrated in the production of automobiles. It has been widely used in various position detection requirements in auto parts processing, engine manufacturing, stamping, painting, welding, assembly, and final assembly of vehicle plants.

Uprox+ sensor requirements for inductive sensors in the development of new automotive material technology
With the rapid development of material technology, the composition of modern automobile manufacturing materials has also undergone major changes. For example, in the manufacture of automobile engines and automobile parts, steel was mostly used as manufacturing materials. However, as automobile materials develop in the direction of lighter weight, resource saving, high performance and high function, they are now gradually using aluminum, aluminum alloy or magnesium aluminum alloy. New composite materials are used instead. For example, to manufacture steel plates for automobiles, in order to meet the needs of light weight, elements such as silicon, manganese, niobium, and titanium are added to the original steel plates to form new composite high-tensile steel plates. Compared with the original soft steel plates, the overall weight of the body Decrease 30~50% while increasing tensile strength and toughness.
Due to the changes in vehicle production materials, traditional sensors will have varying degrees of attenuation when detecting these new composite materials. As a result, automobile manufacturers can only use sensors that use a variety of different detection distances, but this undoubtedly increases the customer’s products. The complexity of use, management and maintenance and aspects also greatly increase the cost of use. In the face of new requirements, Uprox+ sensors have created a new benchmark for “full metal detection” in metal detection, that is, it can detect iron, stainless steel, copper, aluminum and brass with the same high switching distance with the highest accuracy . In this way, the minimum product model can be used to meet the application requirements of different solutions, which greatly simplifies the customer’s product management and reduces the cost of use. Therefore, in this sense, Uprox+ products have the most extensive versatility.

Application of Uprox+ sensor in automotive welding
Welding is one of the most concerned process areas of automobile manufacturers. During the entire welding process, it has to go through 3000-5000 spot welding steps. Due to the continuous improvement of automobile performance and quality requirements, automobile welding processes are becoming more and more complex and advanced. , More types of new materials are applied, and a large number of robots are used to complete the transmission, grasping, clamping, welding and other processes.At the same time, new high-precision position detection sensors that can meet the new technology and the ever-increasing degree of automation are required.
The Uprox+ sensor has a high level of EMC characteristics and strong anti-magnetic field interference due to its innovative PCB coil arrangement structure. Because it does not contain a ferrite core, it is no longer sensitive to AC and DC magnetic fields and can fully resist welding The strong magnetic field generated during the process, and the MT12, MT18, MT30 series with Teflon coating at the same time, can withstand spark splash, mechanical wear and terminal mechanical tension generated during welding. Ensure high reliability and use of product testing Life span has become a “tailor-made” inspection product for automotive welding.

Application of Uprox+ sensor in automobile assembly and painting
In the final assembly and painting workshops of the automobile manufacturing industry, high-volume automobile production requires a high degree of automation. At this stage, the logistics system of storage, lifting, overhaul and conveying adopts advanced modular process assembly technology and a variety of vehicle models. The production of flexible production line technology is equipped with a control system that is efficient, reliable and easy to maintain.
This first requires the use of a large number of, diversified, and highly reliable inductive proximity switches as the detection element of the field device, and the characteristics of the Uprox+ sensor fully meet this requirement. Not only has the high protection level of IP68, but also because of the novel patented coil technology, the Uprox+ sensor has a detection distance increased to 250% compared with the conventional inductive sensor with a ferrite core structure, which can ensure the least use of products. Models to cover the entire on-site testing application, so as to meet the diverse needs of various areas of the site, plus the pre-damping protection characteristics of non-flush products, so that it has the greatest degree of installation freedom, ensuring application under various installation conditions .
For example, the QV40 series products can not only provide a 50mm ultra-large detection distance for the skid body inspection, but also ensure the reliability of the detection when the skid body is traveling due to vibration and deflection, and its unique “detection surface multi-degree freedom” And the characteristics of “quick installation”—the detection surface can be adjusted in multiple directions through the fixture, and it can provide the most convenient installation for the mass use of sensors in the logistics conveying equipment area, plus its unique “pre-damping protection” feature, It can be installed and used in every “corner” of the production line.

Application of Uprox+ sensor in coating production line
It is precisely because of the innovative all-metal detection and other excellent characteristics of the new generation Uprox+ sensor that it can realize most of the applications of automobile production automation detection with only the fewest models, and has the greatest degree of freedom in the solution. Coupled with the product’s high system reliability, it has the widest versatility and applicability in the field of automobile manufacturing.
