Introduction: Solder the robot is to be engaged in soldering (include cut and spray) industrial robot. According to international Organization for Standardization (ISO) industrial robot belongs to a standard to solder the definition of the robot, industrial robot is a kind of multipurpose, the automata manipulator that can repeat process designing (Manipulator) , have 3 or more programmable axis, use at industrial automation domain. Solder the robot is to be engaged in soldering (include cut and spray) industrial robot. According to international Organization for Standardization (ISO) industrial robot belongs to a standard to solder the definition of the robot, industrial robot is a kind of multipurpose, the automata manipulator that can repeat process designing (Manipulator) , have 3 or more programmable axis, use at industrial automation domain. Solder the robot basically includes machine support of the people to solder equipment two parts. The robot is mixed by robot noumenon control ark (hardware and software) composition. And solder equipment, it is with arc solder and spot welding exemple, criterion by solder power source, (include its to control a system) , machine sending silk (arc solder) , welding torch (clamp) wait for a part to comprise. Due still to intelligent robot pass feeling system, be like laser or photograph wait like sensor and its control equipment. Graph 1a, B shows arc welding machine implement person and the basic composition that nod solder robot. Of spot welding robot solder equipment, because used unifinication solder pincers, solder transformer outfit is at the back of solder clamp, so transformer must as far as possible miniaturization. Lesser to the capacity transformer can be versed in with 50Hz frequency communicates, and bigger to the capacity transformer, had begun to use inversion technology to be versed in 50Hz frequency communication turns into communication of 600 ～ 700Hz, make the bulk of transformer decreases, reduce. Transformation hind can use alternating current of 600 ～ 700Hz to solder directly, also can undertake rectification 2 times again, solder with dc. Clamp of this kind of new electric servo spot welding has following advantages: 1) every solder nods solder cycle can be reduced substantially, because of solder clamp opening rate is by the robot accurate pilot, clamp of the mobile process between dot and dot, solder can begin the robot close; And solder is over after, solder clamp is stretched at the same time, the robot is OK at the same time displacement, the robot after clamp of the solder after need not waiting for a robot to reach the designated position just closes or solder clamp is stretched completely is again mobile; 2) solder clamp is stretched degree can adjust arbitrarily according to the circumstance of workpiece, should not produce collision or interference to decrease as far as possible only stretch degree, spend with saving solder clamp to leave, open the time that agrees place to occupy in order to save solder clamp. 3) solder clamp closes when pressurization, press muscularity is small OK adjustment not only, and when close two electrode are to close gently, decrease bump be out of shape and noise.
