Description
Technical Field

[0002] Electric soldering irons are essential tools for electronic production and electrical appliance maintenance. They are mainly used for welding machine components and wires. In particular, internal heating electric soldering irons heat up quickly and do not generate induced current. They are widely used in automated production lines. However, the heating core of internal heating electric soldering irons has a short life span and poor controllability in stable operation. Especially in automated production lines where multiple internal heating electric soldering irons work together, because it is impossible to monitor the life span of the electric heating core, they can only be replaced when the heating core is damaged. Damage will inevitably lead to a reduction in the reliability of the production line processing quality (damage to the electric heating core will cause problems in the welding of the corresponding production process). In order to ensure the stability of the working state of all electric soldering irons in the entire production line, not only the damaged ones need to be replaced, but also the other undamaged electric heating cores need to be replaced as a whole. (The heating cores of the same batch have similar life spans or failure cycles). This method will inevitably cause waste of heating cores.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).
[0019] The internal heating electric soldering iron controlled by a robot on the production line cannot estimate the life of the soldering iron heating core. It can only judge whether it is damaged based on real-time temperature monitoring, and can only be replaced after damage occurs, which will greatly affect the production efficiency of the production line and the reliability of the welding process. In the embodiment of the present application, a soldering iron heating core monitoring system is provided, which dynamically monitors the working parameter information of the internal heating electric soldering iron, and then estimates the life of the soldering iron heating core, so that each internal heating electric soldering iron can replace the soldering iron heating core in time, thereby ensuring the reliability and continuity of the internal heating electric soldering iron production process.
[0020] Embodiment 1: Please refer to Figure 1 , is a functional block diagram of a soldering iron heating core monitoring system in an embodiment, the soldering iron heating core monitoring system includes an inspection unit 1, a work monitoring unit 2, a replacement prompt unit 3 and an information update unit 4. The inspection unit 1 is used to read the identification information of each internal heating electric soldering iron that starts working, and the identification information includes the model information, ID information and working parameter information of the soldering iron heating core in the internal heating electric soldering iron. Among them, the model information is used to identify the model of the soldering iron heating core, the ID information is used to distinguish the soldering iron heating core, each soldering iron heating core corresponds to a unique ID information, and the working parameter information includes the working time, the working temperature error value and / or the number of working times. The working temperature error value is used to identify the temperature error of the soldering iron heating core when it is working. The working time is used to identify the historical working time of the soldering iron heating core, and the number of working times is used to identify the historical number of power on and off of the soldering iron heating core. The identification information is stored in the heating core encryption chip, which is integrated into the internal structure of the soldering iron heating core, and each heating core encryption chip corresponds to a soldering iron heating core. The work monitoring unit 2 is used to record the identification information of each internal heating electric soldering iron, and according to the working state of the internal heating electric soldering iron, track and record the working parameter information of each soldering iron heater, that is, track and record the working time and working times under the current working state. The replacement prompt unit 3 is used to output the indication information of the internal heating electric soldering iron that needs to replace the soldering iron heater according to the working parameter information of each soldering iron heater tracked and recorded, wherein the estimated life value of the soldering iron heater to be replaced is less than a first preset threshold value, and the estimated life value is used to identify the estimated reference threshold value of the predicted pre-damage of the soldering iron heater.

[0021] Due to the differences in the working environment (ambient temperature, humidity and pressure) and working mode (whether it is subjected to external force) of the internal heating electric soldering iron, the life evaluation conditions of the soldering iron heating core are also different. In one embodiment, the life estimation value of the soldering iron heating core is set based on the historical working time of the soldering iron heating core, and its working time is used to identify the historical time for each soldering iron heating core to maintain the working temperature. In one embodiment, the life estimation value of the soldering iron heating core is set based on the historical working times of the soldering iron heating core, and the working times are used to identify the number of times the soldering iron heating core is powered on and off. In one embodiment, the working parameter information also includes the expansion times, and the life estimation value of the soldering iron heating core is set based on the historical expansion times of the soldering iron heating core, and the expansion times are used to identify the number of times the temperature of the soldering iron heating core exceeds the first preset value and then falls below the second preset value, wherein the first preset value is greater than the second preset value. The estimation of the life estimation value based on the expansion times is based on the fact that when the soldering iron heating core changes beyond the preset temperature range, there will be expansion changes, and the number of expansion changes is also an important reference indicator affecting the life of the soldering iron heating core. In one embodiment, the above three estimation methods of life estimation value are comprehensively considered at the same time, and the minimum value among them is taken as the final life estimation value.
