the control panel acquires the environmental temperature information through an environmental temperature sensor;
when the environmental temperature information is lower than a preset low-temperature threshold value, the control panel controls the refrigerating and heating assembly to execute heating operation to heat the laser;
and after the internal temperature of the laser is higher than a preset operation temperature threshold, controlling the refrigerating and heating assembly to stop the heating operation.
9. The method for controlling an air-cooled laser as claimed in claim 8, wherein,
the method further comprises the steps of: after the control board acquires the starting information of the laser, the fan assembly is controlled to start and run, so that the temperature inside the laser is kept consistent;
after the preset time period, the environment temperature information is acquired through the environment temperature sensor, and the operation of the refrigerating and heating assembly is controlled according to the environment temperature information.
10. The method for controlling an air-cooled laser as claimed in claim 8, wherein,
the method further comprises the steps of: the control board acquires the internal temperature information of the laser through the temperature sensor;
when the internal temperature information of the laser is higher than a preset temperature threshold, the control board controls the refrigerating and heating assembly to execute refrigerating operation; cooling the interior of the laser;
the control board also controls the operation of the fan assembly.
