Abstract

The invention provides a device for welding plastic materials in a laser transmission manner. The device comprises a supporting plate, a laser light source and a pressure regulating mechanism, wherein the pressure regulating mechanism comprises a pressing plate mechanism, a supporting plate, a guide rail and a drive mechanism; the pressing plate mechanism is connected with the drive mechanism andis connected with the supporting plate through the guide rail; the pressing plate mechanism is provided with a light-transmitting window consisting of a light-transmitting window opening and a light-transmitting window body; plastic materials to be welded are positioned on the supporting plate and correspondingly arranged below the light-transmitting window; and the laser light source is sequentially connected with the light-transmitting window and the plastic materials to be welded through laser beams. The invention also provides a welding method realized by the device. According to the invention, the plastic materials to be welded are under proper pressure, and further generate secondary polarization to be combined together, thus welding quality and welding strength are ensured.
