Claim Text:
1. A high temperature curing oven for heating a plurality of substrates, comprising: a heating cavity, a heater and a temperature monitor system for monitoring a curing temperature inside the heating cavity, wherein: the heater includes a plurality of heating modules that can be controlled independently, the temperature monitor system comprises: at least one thermocouple for monitoring a temperature information of an inner environment of the heating cavity; an infrared monitor device for monitoring a surface temperature information of each layer of substrates inside the heating cavity and generating a temperature signal according to the surface temperature information; a signal processing module signally connecting to the thermocouple and the infrared monitor device, and generating an executive command when judging that there exists a substrate with abnormal curing temperature which has an excessively high temperature point and/or an excessively low temperature point according to the temperature information from the thermocouple and the temperature signal from the infrared monitor device; and an executing module signally connecting to the signal processing module, and adjusting a heating power of the heating module corresponding to the substrate with abnormal curing temperature in the heater according to the executive command generated by the signal processing module, wherein the infrared monitor device comprises: at least one infrared camera tube, which is disposed inside the heating cavity and monitors the surface temperature information of each layer of substrates inside the heating cavity; a sliding rail, which is disposed on a side wall of the heating cavity; a driving device, which is capable of driving the infrared camera tube to slide along the sliding rail; and an infrared signal receiving-and-processing device, which signally connects to each infrared camera tube and generates the temperature signal according to the surface temperature information, the infrared signal receiving-and-processing device signally connects to the signal processing module.
