Laser drying device and method of use thereof

A laser drying device, comprising a laser drying module, a position sensor, a sensor module and a control system;

• the laser drying module includes semiconductor laser units arranged in an array and electrically connected to the control system;
• the sensor module includes a sensor and a sensor driving unit, wherein the sensor is slidably connected to the sensor driving unit, the sensor driving unit is positioned on a side of the laser drying module;
• the sensor of the sensor module is either a temperature sensor or a humidity sensor;
• the position sensor is placed at an edge of a strip to detect a position of the edge of the strip;
• wherein the sensor driving unit includes a sliding guide and a driving motor, the sliding guide is slidably connected to the sensor and placed on one side of the laser drying module, the driving motor is mounted on one end of the sliding guide and is kinetically connected to the sliding guide;
• and
• wherein the sliding guide includes a chain, a slide groove, a first transmission gear and a second transmission gear, the chain is arranged around the slide groove, and the chain is connected to the first transmission gear at an end and connected to the second transmission gear at the other end;
• a T-shape slider is provided at a connection point of the sliding guide and the sensor, and an horizontal end of the T-shape slider is arranged between the slide groove and a side of the chain away from the laser drying module;
• and the first transmission gear is kinetically connected to an output shaft of the drive motor.
