The figure schematically shows an apparatus according to an embodiment of the present invention. In the figure, 1 is a resin-molded electronic component, and the lead terminal portion 1a of this electronic component 1 is continuous in a hoop shape, and is continuously transferred at a constant pitch in the front and back directions of the paper by an appropriate transfer means (not shown). be done. Reference numeral 2 denotes a laser beam generating device disposed on the side of the transfer path of the electronic component 1. The laser beam generated by this device 2 is emitted toward the transfer path via the irradiation control section 3, and is emitted to the transfer path through the lens. 4 and irradiates the marking surface of the electronic component 1 in a concentrated manner, and by controlling the irradiation direction by the control section 3, the focal point of the laser beam is moved on the marking surface to perform desired laser marking.

いる。 A generated gas suction duct 5 connected to a suction fan (not shown) is arranged near the electronic component 1 that is irradiated with this laser beam.
The opening of this suction duct 5 faces above the marking surface of the electronic component 1 and the back surface thereof. Therefore, the gas smoke generated on the marking surface of the electronic component 1 by the laser beam irradiation is immediately sucked and removed by the opening of the suction duct 5. Furthermore, a nozzle is provided at the front lower part of the electronic component 1 to blow clean air toward the marking surface, thereby purifying the atmosphere near the marking surface.

行えるようになつた。(Effects) As explained above, in the present invention, a suction duct for the generated gas is provided near the electronic components, and this suction duct has openings facing above and on the back surface of the marking surface of the electronic components. As a result, the gas smoke generated on the marking surface of the electronic component by laser beam irradiation is immediately sucked in by the opening of the suction duct and spreads along the entire circumference of the marking surface except at least below. Therefore, it will flow and be quickly removed. Therefore, even if the transfer route for electronic components is enlarged, marking problems caused by gas fumes will no longer occur, making it possible to improve the efficiency of laser marking work. It has also become possible to perform laser marking of color-coated parts that tend to generate gas smoke.
