Controller and Power supply
The controller in the robotic system is the heart of the operation.cnc machining parts The controller stores preprogrammed information for later recall, control peripheral devices, and communicates with computers within the plant for constant updates in production The controllers is used to control the robot manipulator’s movements as well as to control peripheral components within the work cell.
The user can program the movements of the manipulator into the controller through the use of a hand-held teach pendent. This information is stored in the memory of the controller for later recall. The controller stores all program data of the robotic system. It can store several different programs, and any of these programs can be edited。
The controller is also required to communicate with peripheral equipment within the work cell. For example, the controller has an input line that identifies when a machining operation is completed. When the machine cycle is completed, the input line turns on, telling the controller to position the manipulator so that it can pick up the finished part. cnc machining parts Then, a new part is picked up by the manipulator and placed into the machine. Next, the controller signals the machine to start operation.
The controller can be made from mechanically operated drums that step through a sequence of events. This type of controller operates with a very simple robotic system. The controllers found on the majority of robotic systems are more complex devices and represent state-of-the-art electronics. That is, they are microprocessor-operated. These microprocessors are either 8-bit, 16-bit, or 32-bit processors. This power allows the controller to be very flexible in its operation.
The controller can send electric signals over communication lines that allow it to talk with the various axes of manipulator. This two-way communication between the
8 robot manipulator and the controller maintains a constant update of the location and the operation of the system. The controller also controls any tooling placed on the end of the robot’s wrist. The controller also has the job of communicating with the different plant computers . The communication link establishes the robot as part of a computer-assisted manufacturing (CAM) system.
As the basic definition stated , the robot is a reprogrammable , multifunctional manipulator . Therefore , the controller must contain some type of memory storage . The microprocessor-based systems operate in conjunction with solid-state memory devices . These memory devices may be magnetic bubbles , random-access memory , floppy disks , or magnetic tape . Each memory storage device stores program information for later recall or for editing。
The power supply is the unit that supplies power to the controller and the manipulator . Two types of power are delivered to the robotic system . One type of power is the AC power for operation of the controller . The other type of power is used for driving the various axes of the manipulator .
For example , if the robot manipulator id controlled by hydraulic or pneumatic manipulator drives , control signals are sent to these devices ,cnc machining parts causing motion of the robot . For each robotic system , power is required to operate the manipulator . This power can be developed from either a hydraulic power source , a pneumatic power source , or an electric power source , These power sources are part of the total components of the robotic work cell。
