The Wuxi Sigma machine tool robot adopts GSK robot and ABB robot body, which ensures the stability of the robot in hardware. By using Sigma professional application modules accumulated in the automation application of CNC machining industry for many years to connect with the robot's bus, the reliability of the application is guaranteed from the scheme

The Sigma six axis robot solution has the following characteristics:

1. Scalability

The I/O interface can be expanded to 256 points, and can be expanded to 1-2 external axes when needed in production

2. Durable and sturdy

Industrial robots are made of high-strength materials and their arms are mechanically balanced, making them suitable for harsh production environments

3. Easy to operate

The teaching box provides a friendly human-machine dialogue window, with a simple and elegant interface, and rich display and monitoring information

4. High efficiency

By adopting the advanced GSK-RC control system in China, the robot can always optimize acceleration and deceleration according to the actual load, and shorten the operation cycle time as much as possible

5. Strong reliability

The robot monitors its own motion and load situation through a built-in Service Information System (SIS) and optimizes service requirements, with a longer continuous working time

6. Excellent safety performance

By carefully designing protective programs and corresponding protective devices, collisions between robotic arms and machine tools can be effectively prevented It can also be integrated into the Taisho Vision System for real-time visual monitoring of the work environment, ensuring the safety of personnel, machine tools, and robots

7. Stable high-precision performance

It has high repeatability positioning accuracy, and under long-term working conditions, the robot's high accuracy is not affected, ensuring the stability of part production quality

8. Material reverse recognition device

The mechanical hand claw is equipped with a high-precision measuring device, which can correctly identify whether there is material, whether there is no material, whether there is reverse material, and whether the size is qualified

9. Robot gripper can be replaced at will

Based on the different dimensions and shapes of the processed workpieces, robots can replace or install claws according to actual needs

Robot working diagram

Schematic diagram of feeding mechanism

This institution consists of a positioner, photoelectric sensor, turntable, support, positioning column, etc There are a total of 60 workstations in this silo, with 30 workstations inside and outside respectively, using a staggered design. Each time, the robot first takes the raw materials from the outer 30 workstations until they are processed, and then takes the raw materials from the inner 30 workstations (The number of workstations can be increased or decreased according to the actual needs of the user)

Schematic diagram of robot hand grasping and clamping

The robot adopts two claws, one for feeding and the other for receiving. The mechanical claws can be replaced according to the product shape, and various auxiliary claws can be added as needed. One robot can simultaneously load and unload multiple CNC machine tools

We will choose ABB robots and GSK robot bodies based on the actual environment of the customer:
