Thermal imaging surface processing auxiliary system and method

A thermal image surface processing auxiliary system, applicable for a surface processing apparatus that uses a grinding tool to perform surface processing on at least one workpiece, comprising:

• a thermal imaging sensor configured to photograph at least one of the grinding tool and the at least one workpiece to generate at least one thermal image;
• a computing device connected to the thermal imaging sensor and configured to obtain a temperature change of an observation area in the at least one thermal image, control the surface processing apparatus to move the grinding tool toward the at least one workpiece at a speed greater than a preset processing speed when the temperature change is not greater than a preset critical value, and control the surface processing apparatus to move the grinding tool toward the at least one workpiece at the preset processing speed when the temperature change is greater than the preset critical value,
• wherein the observation area corresponds to a portion other than a contact portion of the grinding tool with the at least one workpiece,
• wherein the computing device is further configured to determine whether a moving distance of the grinding tool is greater than a first preset distance when determining that the temperature change is not greater the preset critical value, control the surface processing apparatus to move the grinding tool toward the at least one workpiece at a first preset speed when determining that the moving distance of the grinding tool is not greater than the first preset distance, and control the surface processing apparatus to move the grinding tool toward the at least one workpiece at a speed smaller than the first preset speed when determining that the moving distance of the grinding tool is greater than the first preset distance, and
• wherein the computing device is further configured to determine whether the moving distance of the grinding tool is greater than a second preset distance when determining that the moving distance of the grinding tool is greater than the first preset distance, control the surface processing apparatus to move the grinding tool toward the at least one workpiece at a second preset speed when determining that the moving distance of the grinding tool is not greater than the second preset distance, and control the surface processing apparatus to move the grinding tool toward the at least one workpiece at a third preset speed smaller than the second preset speed when determining that the moving distance of the grinding tool is greater than the second preset distance, wherein the second preset distance is greater than the first preset distance.
