PURPOSE:To dispense with a preparatory operation where electronic parts are previously set uniform in polarity by a method wherein the electrodes of the electronic part provided with a pair of electrodes formed different from each other in shape so as to be recognized in polarity are recognized by a recognition camera, whereby the electronic part is corrected in polarity and positional deviation to a suction nozzle. CONSTITUTION:Two separate electrodes 2 and 3 are formed on the underside of the primary plane of an electronic part 1, where the electrodes 2 and 3 are formed different from each other in shape so as to be easily distinguished from each other at recognition. An electronic part 1 uncertain in polarity and housed in a part feeder 4 is sucked by a suction nozzle 58 connected to a rotary table 64 at a point E and moved to a point G by the intermittent motion of the rotary table 64. Then, the polarity and the positional deviation DELTAX, DELTAY, and DELTAtheta of the electronic part 1 are detected by a recognition camera 59 at, a point G. The part 1 is corrected in deviation by an angle of DELTAtheta by a corrector 62 at a point H and then corrected by distances of DELTAX and DELTAY along the axes of X and Y at a point I and then mounted. |
