Two calibration rods 402 are slidably mounted on the housing 401. The two calibration rods 402 are perpendicular to each other, with one end being a contact end and the other end being a detection end. The contact ends of the two calibration rods are brought close together to form a detection port. Two photoelectric sensors 403 are mounted on the housing 401. The positions of the two photoelectric sensors 403 correspond to the detection ends of the two calibration rods 402. Specifically, when the soldering iron tip 1 is at the position of the contact end of the contact rod, the sensor calibrates the contact end of the contact rod. When testing, the soldering iron tip 1 presses firmly against the two calibration rods 402 on the calibration sensor 4. When the soldering iron tip 1 moves, the two calibration rods 402 move along the axis of the calibration rods 402 toward the contact end of the calibration rods 402. The photoelectric sensor 403 is provided with a light-transmitting hole, which corresponds to the position of the calibration rods 402. When the contact ends of the two calibration rods 402 move toward the photoelectric sensor 403 until they enter the light-transmitting hole, the photoelectric sensor 403 sends a detection signal. Then, the position of the soldering iron tip 1 is adjusted so that the contact ends of the calibration rods 402 move in the opposite direction so that they just leave the light-transmitting hole. At this time, the movement of the soldering iron tip 1 is stopped, and the soldering iron tip 1 reaches the ideal coordinate position.
