Soldering iron calibration method

Abstract

The invention discloses a soldering iron calibration method, belongs to the calibration technology field and is based on the soldering iron calibration structure. The soldering iron calibration structure comprises a support, a detection switch, a soldering iron driven by a linear servo mechanism and a soldering iron tip mounted on the soldering iron, wherein the support is equipped with a guide shaft in a sliding mode, one end of the guide shaft is provided with an insulation element, the other end is provided with a detection piece, the detection switch is electrically connected with an electrical control unit, the electrical control unit is electrically connected with the linear servo mechanism, the soldering iron tip is driven by the linear servo mechanism to move and contact the insulation element, the detection piece is further driven to move, when a signal is detected by the detection switch, position data of the linear servo mechanism is read by the electrical control unit, position data of a linear servo mechanism of a standard soldering iron tip is compared with the position data of the linear servo mechanism of the detected soldering iron tip, and difference is the compensation amount. The soldering iron calibration structure is advantaged in that welding defects caused by wear, corrosion and replacement of the soldering iron tip can be reduced, and stability, consistency and the utilization rate of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of calibration, and in particular relates to a method for calibrating a soldering iron. Background technique [0002] In the production of electronic products, the joints of components need to be soldered. For example: in the assembly process of LCM (LCD Module, liquid crystal display module), the backlight pins of BL (Back Light, backlight board) and the pads of FPC (Flexible Printed Circuit, flexible circuit board) need to be connected by soldering. A soldering iron is the most commonly used soldering tool. [0003] In the process of automatic welding production, due to the needs of the process, it is required to ensure that the gap between the soldering iron tip of the soldering iron and the pad is within a certain range, otherwise poor welding will easily occur. However, during the long-term use of the soldering iron tip, the gap between the soldering iron tip and the pad will continue to increase due ...

AI Technical Summary

Problems solved by technology

During the long-term use of the soldering iron tip, the gap between the soldering iron tip and the pad will continue to increase due to wear and corrosion.

In addition, because the height consistency of the soldering iron tip itself is not good, after replacing the soldering iron tip, the gap between the new soldering iron tip and the pad will also change

If it is adjusted manually, it will take a long time, and the requirements for the calibration personnel are high
