OLED laser welding system and temperature control method

The embodiment of the invention belongs to the field of laser welding, and relates o an OLED laser welding system and a temperature control method. The OLED laser welding system provided by the invention comprises a laser unit, a welding head and a temperature detecting module, wherein the laser unit is separately connected to the welding head and the temperature detecting module; laser output bythe laser unit is transmitted to a welding point through the welding head; the temperature detecting module detects the temperature of a welding point through a noncontact way and a contact way, and transmits a first detected temperature and a second detected temperature to the laser unit, so that the laser unit regulates output power of laser according to the first detected temperature and the second detected temperature. The OLED laser welding system can ensure detection precision and quickness on the temperature of the welding point, and further can ensure reliability of the detected results, so that regulation of
