Boosting Sensor Resilience in Welding With Self-Bunkering Inductive Proximity Sensors

A welding cell will press the limits of any sensor placed in its proximity. Avoiding weld spatter, magnetic fields, extreme temperatures, and impact damage are common challenges in a harsh welding environment. And when sensors fail in these conditions, it can significantly disrupt production uptime. To prevent such disruptions, manufacturers explore more robust sensor mounting solutions, such as proximity mounts, bunker blocks, and other protective devices to shield sensors from these harsh conditions. The self-bunkering inductive proximity sensor plays a key role in alleviating the issues, especially in situations where other accessories are not an option due to limited space.

Weld spatter and magnetic field resistant

In many welding applications, the substantial currents involved can generate heightened magnetic fields, making a welding cell vulnerable to interference. This interference can lead a basic proximity sensor to trigger, even though a part may not be present. The self-bunkering proximity sensor is designed to resist magnetic fields, allowing it to work much closer to the welding surface than a typical inductive sensor. Additionally, the sensor comes with a polytetrafluoroethylene (PTFE) weld coating, allowing for easy removal of the spatter buildup with abrasive tools like a wire brush.

Guard against heavy impacts

Again, the self-bunkering inductive proximity sensor is built for rugged environments. It features a thick, strong one-piece connector body and super thick brass housing to buffer the internal electronics from external impacts and conductive heat. It also includes a deflection ring and a non-brittle, ferrite-free coil carrier to protect the sensor face from direct impacts, disperse shock, and safeguard internal sensing components. The wide-radius corners offer stress relief at the major junction points of the connector body and housing.

Withstand extreme temperatures

With a ceramic PTFE-coated face plate, the sensor can resist up to 2200°F weld spatter burn through from the front. The rest of the body, coated with PTFE and paired with an extra-thick brass housing, provides protection for the sensor up to 300°F. This means that if the sensor is properly maintained, its lifetime should be quite a bit longer than a standard inductive sensor.

Don’t replace, defend

The core components of the proximity sensor can be destroyed if any of the three critical failures – conducted heat, impact, or spatter – occur in combination. To prevent this, the product incorporates a collection of design measures intended to create a virtually impenetrable shield around the internal critical components.

In summary, the self-bunkering inductive proximity sensor is a key solution to combat the challenges sensors face in harsh welding environments that will ultimately disrupt production. Its resistance to magnetic fields and ability to withstand heavy impacts and extreme temperatures, especially in situations with limited space, ensures the protection of the critical sensor components and extended sensor lifespan.

Exploring Industrial Cameras: A Guide for Engineers in Life Sciences, Semiconductors, and Automotive Fields 

In the bustling landscape of industrial camera offerings, discerning the parameters that genuinely define a camera’s worth can be a daunting task. This article serves as a compass, steering you through six fundamental properties that should illuminate your path when selecting an industrial camera. While the first three aspects play a pivotal role in aligning with your camera needs, the latter three hold significance if your requirements lean towards unique settings, external conditions, or challenging light environments.

    1. Resolution: unveiling the finer details. Imagine your camera as a painter’s canvas and resolution as the number of dots that bring your masterpiece to life. In simple terms, resolution is the number of pixels forming the image, determining its level of detail. For instance, a camera labeled 4096 x 3008 pixels amounts to a pixel symphony of around 12.3 million, or 12.3 megapixels. Yet don’t be swayed solely by megapixels. Focus on the pixel count on both the horizontal (X) and vertical (Y) axes. A 12-megapixel camera might sport configurations like 4000 x 3000 pixels, 5000 x 2400 pixels, or 3464 x 3464 pixels, each tailor-made for your observation intent and image format.
    1. Frame rate: capturing motion in real-time. The frame rate, akin to a movie’s frame sequence, dictates how swiftly your camera captures moving scenes. With figures like 46.5/74.0/135 denoting your camera’s capabilities, it reveals the number of images taken in different modes. Burst mode captures a rapid series of images, while Max. streaming ensures a consistent flow despite interface limitations. The elegance of Binning also plays a role, making it an adept solution for scenarios craving clarity in dim light and minimal noise.
    1. Connectivity: bridging the camera to your system. The camera’s connectivity interfaces, such as USB3 and GigE, shape its rapport within your system.

USB3 Interface: Like a speedy expressway for data, USB3 suits real-time applications like quality control and automation. Its straightforward nature adapts to diverse setups.

GigE Interface: This Ethernet-infused interface excels in robust, long-distance connections. Tailored for tasks like remote monitoring and industrial inspection, it basks in Ethernet’s reliability.

    1. Dynamic range: capturing radiance and shadow. Imagine your camera as an artist of light, skillfully capturing both dazzling radiance and somber shadows. Dynamic range defines this ability, representing the breadth of brightness levels the camera can encapsulate. Think of it as a harmony between light and dark. Technical folks may refer to it as the Ratio of Signal to Noise. It’s influenced by the camera’s design and the sensor’s performance. HDR mode is also worth noting, enhancing contrast by dividing the integration time into phases, each independently calibrated for optimal results.
    1. Sensitivity: shining in low-light environments. Your camera’s sensitivity determines its prowess in low-light scenarios. This sensitivity is akin to the ability to see in dimly lit spaces. Some cameras excel at this, providing a lifeline in settings with scarce illumination. Sensitivity’s secret lies in the art of collecting light while taming noise, finding the sweet spot between clear images and environmental challenges.
    1. Noise: orchestrating image purity. In the world of imagery, noise is akin to static in an audio recording—distracting and intrusive. Noise takes multiple forms and can mar image quality:

Read noise: This error appears when converting light to electrical signals. Faster speeds can amplify read noise, affecting image quality. Here, sensor design quality is a decisive factor.

Dark current noise: Under light exposure, sensors can warm up, introducing unwanted thermal electrons. Cooling methods can mitigate this thermal interference.

Patterns/artifacts: Sometimes, images bear unexpected patterns or shapes due to sensor design inconsistencies. Such artifacts disrupt accuracy, especially in low-light conditions. By understanding and adeptly managing these noise sources, CMOS industrial cameras have the potential to deliver superior image quality across diverse applications.

In the realm of industrial cameras, unraveling the threads of resolution, frame rate, connectivity, dynamic range, sensitivity, and noise paints a vivid portrait of informed decision-making.

From Wired to Wireless Automation Advancements in Automotive Manufacturing

Looking back, the days of classic muscle cars stand out as a remarkable period in automotive history. Consider how they were built, including every component along the assembly line connected through intricate wiring, resulting in prolonged challenges related to both wiring and maintenance. Advancements in technology led to the introduction of junction blocks, yet this didn’t entirely solve the persistent problems associated with time and connections.

In the mid-2000s, a collaborative effort among multiple companies resulted in the development of the IO-Link protocol. This protocol effectively tackled the wiring and maintenance issues. Since its inception, IO-Link has continued to progress and evolve.

In 2023, we’re taking the next step with a wireless IO-Link master block.

In modern manufacturing, the process involves using independently moving automated guided vehicles (AGVs), also known as skillets. These AGVs are responsible for performing various tasks along the production line before completing their circuit and returning to their initial position. Initially, when these AGVs were integrated, each of these skillets was equipped with a programmable logic controller (PLC), which incurred significant expenses and extended the setup time. Additionally, the scalability of this system was limited by the available IP addresses for the nodes.

Demand for wireless IO-Link blocks

In recent years, there has been a growing demand for wireless IO-Link blocks. Now, a solution to meet this demand is available. The wireless IO-Link block works in a manner similar to the existing current blocks but without the need for a PLC, simplifying wiring and using existing Wi-Fi infrastructure.

Imagine a conveyor scenario where numerous AGVs follow a designated path, each with a hub attached. The setup would look something like this: up to 40 hubs communicating simultaneously with a central master. Each hub has the capacity to accommodate up to eight connected devices, resulting in a total of 320 distinct IO points managed by a single IO-Link master.

Communication among these blocks employs a protocol akin to that of a cell phone. As an AGV transitions from one master hub to another, it continues to transmit its data. Within each hub, an identity parameter not only designates the specific hub but also identifies the associated skillets and the location within the manufacturing plant.

Transitioning to a wireless system leads to a substantial reduction in your overall cost of ownership. This includes decreased setup times, simplified troubleshooting, lower maintenance efforts, and a reduced need for spare parts.

We are in an exciting time of technological advancement. Make sure you are moving alongside us!

Standardizing Sensors and Cables for Improved End-User Experience

The concept of product standardization holds a crucial role in the realm of manufacturing, particularly for companies with numerous facilities and a wide array of equipment suppliers. The absence of well-defined standards for components integrated into new capital equipment can lead to escalated purchasing expenses, heightened manufacturing outlays, increased maintenance costs, and more demanding training requirements.

Sensors and cables must be considered for these reasons:

    • A multitude of manufacturers of both sensors and cables, which can lead to a myriad of choices.
    • Product variations from each manufacturer in terms of product specifications and features, which can complicate the selection process.

For example, inductive proximity sensors all share the fundamental function of detecting objects. But based on their specific features, some are more suitable for specific applications than others. The situation is mirrored in the realm of cables. Here we look at some of the product features to consider:

Inductive Proximity Sensors Cables
 

·    Style:  tubular or block

·    Size and length

·    Electrical characteristics

·    Shielded or unshielded

·    Sensing range

·    Housing material

·    Sensing Surface

 ·    Connector size

·    Length

·    Number of pins & conductors

·    Wire gage

·    Jacket material

·    Single or double ended

In the absence of standardized norms, each equipment supplier might opt for its favorite source, often overlooking the impact on the end user. This can lead to redundancies in inventories of sensor and cable spare parts and even the use of components that are not entirely suited for the manufacturing environment. The ripple effect of this situation over time can result in diminished operational efficiency and high inventory carrying costs.

Once the selection and purchasing of sensors and cables are standardized, the management of inventory costs will coincide. Overhead expenses related to purchasing, stocking, picking, and invoicing will also go down. The process becomes more efficient when standardized components and materials that are readily available are employed, resulting in reduced inventory levels. Moreover, standardization with the right material selection contributes to decreased manufacturing downtimes.

Also, this transition empowers companies to reassess their existing inventory of cable and sensor spare parts. Through the elimination of redundancy and the elevation of equipment performance, the physical footprint of spare parts inventory can be significantly diminished. Executed adeptly, the act of standardization not only simplifies supply chain management but also extends the mean time between failures while concurrently reducing the mean time taken for repairs.

Driving Efficiency and Reliability in Automotive Manufacturing

In the days of Henry Ford – when you could get a car in any color as long it was black – the assembly line involved grabbing a part and putting it on the car. Today, there are literally thousands of iterations of car options, drastically increasing the need for tracking and traceability of all parts that go into the cars. How do you ensure that the components going into vehicles are the correct ones?

Limitations of traditional barcode stickers

The answer is ever-evolving. At first, automotive companies were printing off one-dimensional barcodes on stickers – a time-consuming, labor-intensive, and often wasteful process. It was necessary for an individual to print a stack of stickers hoping that they were correct and in the right order, manually put them on the parts, and hope they wouldn’t fall off. Unfortunately, many times they did fall off, leaving the operators without a way to track the parts. And once the part hit the assembly line, the operator had to manually scan the barcode, which typically took six to 10 seconds.

The power of optical identification sensors

Modern automotive companies are automating this process with sensors for optical identification. They can reliably and precisely read both 1D and 2D bar codes. This two-step process includes:

    1. Using lasers (CO2 for plastic or Fiber for metal), a Direct Part Mark (DPM) is permanently etched onto the component. This DPM remains readable throughout the component’s lifespan.
    2. Once marked, a nest is created on the component, equipped with two to four cameras. These cameras capture visible 2D data matrices or 1D sticker barcodes from up to 600mm away. All data is transmitted via IO-Link to the PLC. This process eliminates scanning errors and reduces scrap.

Advanced condition monitoring for quality and efficiency

In addition to code reading functions, advanced condition monitoring capabilities have become an essential part of ensuring quality and efficiency in automotive manufacturing. These capabilities enable the continuous monitoring of various parameters related to the components and their operational conditions. Sensors equipped with advanced condition monitoring features, such as temperature sensors, vibration sensors, humidity sensors, inclination sensors, signal quality sensors, and operating time sensors, are deployed alongside the code reading sensors.

Overall, the combination of code reading sensors and advanced condition monitoring capabilities ensures not only the correct identification and traceability of components but also enhances overall quality control, reduces downtime, minimizes scrap, and improves the reliability and performance of the final products.
