Abstract
Provided is a laser welding device using a laser to fuse resin material parts to each other, and more particularly, a thermosetting resin laser welding device fixing a fusion target by using a transparent fixing member to perform fusion while a laser is emitted to an exact fusion point, and capable of emitting the laser to the fusion point by using a refraction of the laser even when an obstacle is present in a straight line between a laser light source and the fusion point.
Claims16
A laser welding device for fuse-joining the first part and second part of a fusion target, in which the fusion target includes the first part made of a laser-transmitting resin material and disposed on one side and the second part made of a non-laser-transmitting resin material and in contact with the other side of the first part, the device comprising:
- a laser light source disposed to be spaced apart from the one side of the fusion target and emitting a laser to one surface of the second part to fuse the second part;
- and
- a fixing member in contact with one surface of the first part and supporting one side of the first part,
- wherein the fixing member is made of a transparent material through which the laser is transmitted.
