The automatic gelatinizing system described in this paper adopts a DRC robot controller and a programmable controller (PLC) as its core. The DRC controller receives signals from the glue gun, cylinder sensors on the worktable, arms' limit switches of the SCARA robot, control signals from PLC, and so on. After systematic calculation and analysis, the DRC drives the robot's motors of every axis, electromagnetic valves, indicator lights, ancillary components on the claw, etc. The PLC receives input signals from the robot controller and detection sensors to control the air cylinder of clamps, loading and unloading devices, support panel and electrical motors, and it can also control the motor of the feeding glue system precisely. An automatic off-line programming system is developed with Visual C++ 6.0 programmable language to solve problems in the course of applying automatic gelatinizing robot, by which the users can easily design their own gelatinizing schemes at their will according to different gelatinizing tasks.
