A kind of nut-welding leakproof automatic testing method utilizing nut-welding leakproof automatic detection device in described auto production line to realize, this detection method comprises the following steps:
1) shelter target plate follow rush welding cylinder press to weld pedestal upper surface；
2) judge to weld according to induction module and whether have on pedestal the nut, concrete judge process to be:
If sensitive side photoelectric sensor is lighted, i.e. the light beam of emission side photoelectric sensor passes through at the sipes present position on shelter target plate, then be judged to weld on pedestal and have nut, enter step 3)；If sensitive side photoelectric sensor is not lighted, i.e. shelter target plate blocks the light beam of emission side photoelectric sensor, then be judged to weld without nut on pedestal, enter step 4)；
3) nut on welding pedestal is welded by welding rifle, enters step 5)；
4) projection welding special plane power-off, stops welding, waits that workman enters step 5 after laying nut and being energized)；
5) rush welding cylinder and lead shifting on shelter target plate, return step 1).
Compared with prior art, the method have the advantages that
(1) module is blocked in cooperation, and induction module only need to sense light beam and i.e. can determine whether the existence of nut, it is not necessary to directly sense nut, and this induction mode improves the accuracy of detection；
(2) in device, the width of sipes is set to 1 millimeter, only has the nut of several millimeters to be also convenient for realizing detection for thickness, and accuracy of detection is high；
(3) package unit is detection automatically, and automatic performance is high, and production efficiency is high；
(4) only need to arrange shutter on projection welding special plane can realize automatically detecting with photoelectric sensor, installation cost is low and is easy to maintenance, improves production efficiency.
