Abstract

The invention relates to the field of automatic production of automobiles, in particular to an independent automatic electrode cap replacement unit comprising an electrode cap removal unit, an electrode cap storage unit and a sensing detection unit. The electrode cap storage unit and the sensing detection unit are disposed on two sides of the electrode cap removal unit and are connected in a quick plugging manner. The sensing detection unit comprises an electrode cap removal detection sensor, two electrode cap amount detection sensors and two travel detection sensors. The independent automatic electrode cap replacement unit has the advantages that the unit which is highly modular can be combined with any automatic grinder to allow for automatic die repair and cap replacement, and the function can be updated for customers still replacing caps with hands; the twist and pull cap removal technology is utilized innovatively, efficiency and reliability are improved greatly, upper and lower electrode caps are removed respectively with the cap replacement unit in different rotation directions, the risk of electrode bar looseness due to cap removal torque can be reduced, the electrode cap storage unit can be removed freely, and the size of the whole cap replacement unit is reduced.

Description

technical field

[0001] The invention relates to the field of automatic manufacturing of automobile production, in particular to a self-contained electrode cap automatic replacement device. Background technique

[0002] At present, modern automobile production lines generally use robots for spot welding of automobile body-in-white. The intelligent high-speed movements of robots can meet the high production capacity requirements of automobile production, but the electrodes used for welding are frequently switched on and off and pressure is applied during robot welding. The electrode wears quickly, and the surface of the electrode is easy to form an oxide layer, which will damage the electrode. The damaged electrode will seriously affect the welding quality of the body in white. In order to eliminate the electrode wear and the adverse effect of the electrode oxide layer on welding, the usual practice is to After the electrode is used for a certain number of times, the electrode...
