SVIA's Pickvision vision system puts eyes on the robot

SvenskIndustriautomation (SVIA) is a fast-growing automation company based in Jnkping, Sweden, which has developed robotic systems for customers in the Nordic countries, Germany, the UK, the Netherlands and the United States. The system is combined into robotic units that can communicate with other systems in the plant. At the heart of the robotic unit is SVIA's Pickvision vision system, which detects specific objects on the conveyor belt and picks up objects accurately. Simply put, SVIA puts the eyes on the robot. This revolutionary technology has become popular in the automation market, so SVIA's sales have doubled in the past few years.

Our strength lies in simplicity, says AndersMandorsson, SVIA's designer and project manager, telling the robot how easy it is to pick up objects from the conveyor. The user uses the Pickvision software to take a picture of the object that will be picked up from the belt. The software automatically detects the shape of the object and displays it in the camera each time, so the robot can determine how to pick it up.

Connect DeviceNet and PROFIBUS

As the most advanced automation system, SVIA's robotic units need to be connected to certain factory-level industrial networks, and such communication problems are not always going well. A few years ago, we built a robotic unit for a customer who promised to have access to their PROFIBUS system, but then our system only served as a separate node in its network. At this time, we found the AnybusX-Gateway gateway of HMS. We tried to install one in the electric control cabinet, and then successfully realized the conversion between the DeviceNet system and the customer's PROFIBUS system. AndersMandorsson said.

Since then, SVIA has used the AnybusX-Gateway Gateway in many of the robotic units delivered to customers worldwide. AndersMandorsson once again stressed that simplicity is extremely important. We use DeviceNet in most electrical control cabinets, instead of having to deal with other networks, we installed HMS's X-Gateway gateway, which is reasonably priced, but most importantly, it can make Customers clearly separate our systems from their own factory networks, AndersMandorsson said.

working principle

SVIA's robotic units are usually equipped with ABB robots based on a DeviceNet network. These robots can communicate with another DeviceNet network simply, but if you want to connect to another network, such as a PROFIBUS network (using Siemens PLC) or connect to an EtherCAT network. (using Beckhoff's PLC), you need an interpreter. The AnybusX-Gateway gateway is able to switch between the two networks with built-in software, rebuilding the message from one end and making it understandable on the other end. Configuration using the AnybusConfigurationManager software takes only a few minutes and no programming is required.

High flexibility

SVIA's robotic units are flexible and easy to adjust for different customer needs such as installation, packaging, drilling and planing. With the AnybusX-Gateway gateway, SVIA can be flexible with respect to the network it can connect to. To be frank, we really don't think too much about the network, AndersMandorsson said that when we created the robot system, we just ordered the X-Gateway gateway to switch to the customer's industrial network—plug and play.

In Pickvision, the operator decides what to pick from the conveyor. Each object is photographed and the software automatically recognizes the shape.

When the robot unit is running, the top camera monitors the conveyor belt...

So the robot knows exactly what to pick and how to pick it up.

The AnybusX-Gateway gateway completes the conversion between the DeviceNet system of the robotic control cabinet and the PROFIBUS network of the end customer.

The Rectifier Bridge is to seal the rectifier in a shell. Divided into full bridge and half bridge. The full bridge seals the four diodes of the connected bridge rectifier circuit. The half bridge is to seal together half of the four diode bridge rectifiers. Two bridges can be used to form a bridge rectifier circuit. One half bridge can also form a full-wave rectifier circuit with a center tap of the transformer. Rectifier circuit and operating voltage.
