Now, mechanical hand automation has become inevitable, mechanical automation is unstoppable. Fieldbus is a well known and widely used relatively mature control system technology. The safety of mechanical automation is still very important, safety must be the first and safety bus has been paid attention to. Considering the traditional security measures, especially in the automotive industry a higher degree of automation of welding workshop and assembly workshop, welding robot and assembly manipulator, added a lot of risk, the use of safety protection sensors such as scanner, An Quansuo, emergency stop switch has been very common, but the non bus control system control system of these safety devices remain in the "relay" or "PLC" low-level control state.
The main difference between a secure bus system and a standard bus system is the standard of the communication protocol. The security of the secure bus system is an extension of standard protocols that allow standard and security devices to run on the same network. Its unique feature lies in the realization of secure communication without expensive hardware devices such as gateways, bridges and so on, which can be realized only through software layer. The hand and wrist of an injection molding machine is a part of the hand and arm that adjusts or changes the orientation of the workpiece, thus having independent degrees of freedom to allow the robot to adapt to complex motion requirements. The main weight of the main manipulator is the main parameter of its specifications. At present, the maximum grip weight of the manipulator is about 10 kilograms, and the grip weight is half of the high-speed action. When using suction cups, the weight of 5 kilograms can be absorbed.
The nature of the non-standard manipulator manufacturers learned people generally think that just by changing the software to change the bus system is a kind of dangerous behavior, but it is a security protocol inherent safety bus system to ensure the safety of the whole system.
