THE EQUALIZING SPOT WELDING METHOD FOR SPOT WELDING GUN DEVICE

摘要

PURPOSE: balanced spot welding method prevents that poor weld will not be deposited in normotopia even if substrate since spot-welding gun does not interfere promotion substrate and increases using the offer of large spot welding gun. ;CONSTITUTION: balanced spot welding method using large spot welding gun include: input step angle-data spot-welding gun (30) from robot controller (60) in real time to system control panel (70, PLC); The air pressure equalisation cylinder (50) of step is exported according to angle information, these are input to the system control panel (70) and information, these system detections to control panel (70), spot-welding gun (30); The substrate (80) of the step of contact is balanced with lower end (20) progress, improves cylinder (50); Pass through the substrate (80) that welding gun is pressurizing cylinder (40) in step (10) operation upper part end, applies electric current upper end (10) and lower end (20) between point weldering base material (80); The mobile upper end of step (10) returns to lower end (20) by balance cylinder (50), so that electrode is opened by welding gun cylinder (40) to initial position; And the mobile spot-welding gun (30) is to open upper end (10) and lower end (20) with a gap between next welding point. In the output pressure of the step, the air pressure equalisation cylinder (50) setting stops rising, lower end (20) and substrate (80) when lower end (20). ;The 2013 of copyright KIPO submissions;Touch screen on [Reference numerals] (A1) input control pressure value equalizing cylinder; According to welding gun (A2) type, angle (on-the-spot test value); (BB) detection welding gun uses system control panel (PLC control panels); (CC) the robot control angle of transferring robot is from panel to system control panel; (D1) complete movement robot is to welding position; (D2) welding signal (welding condition) is exported; (EE) export Balance route condition (according to gun type, angle); (FF) improve equalizing cylinder (according to gun type, angle); (GG, KK) compares data (current ranking value is compared); (HH) top out equalizing cylinder (weight with panel for keeping balance); (I1) spot welds; (I2) pointed superior pressing panel is reduced; (I3) apply welding current; It improves (J1) and completes spot welding (upper end); (J2) equalizing cylinder (pressure output control) is reduced; (LL) equalizing cylinder is reduced; (MM) mobile robot (next welding position); Due to error (NN) arrestment
