In the context of Industry 4.0, which focuses on high-end equipment manufacturing , more and more companies are beginning to realize the important role of intelligent manufacturing in improving production efficiency and reducing costs.
To create more advanced automated dispensing equipment, a dispensing robot manufacturer has partnered with Baumer to produce more precise and reliable intelligent dispensing equipment based on Baumer's laser rangefinder sensing technology. Let's take a look!
High-quality dispensing challenge
The dispensing process is a challenge of speed and precision. For example, in the process of dispensing or coating adhesives for mobile phone screens, if there are problems such as uneven thickness, glue end-capping, or glue dripping, it will lead to air bubbles and glue overflow in the subsequent bonding process, resulting in quality problems such as glare and yellowing of the mobile phone screen.
In other words, ensuring the uniformity and consistency of adhesive thickness is one of the important factors affecting product quality. If the thickness is too thin, some products may not achieve the required bonding and protection, while if it is too thick, it may increase the product weight and waste adhesive material.
Controlling the dispensing thickness requires, firstly, accurately determining the distance between the nozzle tip and the working surface; secondly, ensuring consistent dispensing thickness necessitates extremely high dispensing repeatability. Furthermore, the dark color of common dispensing objects, such as PCB boards, can also complicate sensor detection.
OM70 ensures excellent dispensing performance.
The dispensing equipment manufacturer has incorporated the OM70 high-precision laser sensor into its desktop dispensing machine to detect height information before dispensing, thus guiding the dispensing thickness.
According to the requirements of the dispensing process, the spot size of the OM70 laser sensor can be controlled within 0.05mm and the repeatability can be controlled within 5μm. For dark objects such as PCB boards, the OM70 has an automatic exposure compensation function, which can reliably achieve continuous laser detection.
In fact, the Baumer OM70 high-performance laser rangefinder sensor boasts a wealth of features, including automatic exposure control and adjustable data filters, ensuring stable measurement signals and easily completing measurements even under harsh conditions such as ambient light interference. With sub-micron repeatability and extremely low linearity, this series of sensors enables reliable measurement of components and high-precision positioning of objects or robotic grippers, ensuring extremely high process stability even under fluctuating temperature or changing ambient light conditions.
For dispensing machine applications, the OM70 point laser rangefinder sensor features an extremely small spot size, making it ideal for inspecting the position and height of small parts and objects. It ensures high-precision measurements even on difficult-to-measure surfaces.
Furthermore, in terms of ease of use, the OM70 features an integrated web interface that allows for real-time data monitoring and rapid optimization based on specific measurement tasks, facilitating debugging and installation. Simultaneously, its advanced OPC/UA interface and various mainstream industrial communication interfaces enable easy system integration, providing a solid foundation for building flexible dispensing production lines and achieving Industrial Internet of Things (IIoT) goals.
With the rapid development of automation technology, the popularization of intelligence, and the assistance of the Baumer OM70 high-performance laser rangefinder sensor, fully automatic dispensing machines have been applied in many process links, with obvious advantages such as high speed, high efficiency, high precision, and high consistency. The dispensing process is flawless!
