System for optimizing electrode cap welding

Abstract

The invention discloses a system for optimizing welding of an electrode cap, which comprises a sensor, a current sensor of the sensor is connected with a single chip microcomputer, the single chip microcomputer converts a signal of the current sensor into a digital signal, then the digital signal is stored in a storage module, and the storage module carries out simple processing such as filtering on collected current data; the analysis module is used for acquiring the digital signal processed by the single chip microcomputer and the diameter signal of the end face of the electrode, automatically matching and comparing the digital signal and the diameter signal with electrode cap parameters imported into the system, and generating an adjustment factor alpha; and the current adjusting module is used for receiving the adjusting factor alpha obtained by the analysis module and adjusting the real-time current of the welding machine, so that the welding machine is maintained to be output at the current value I. The current of the welding gun can be effectively controlled, the output current of the welding machine is within an effective range, and the problem that the current is too large or too small is avoided.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a system for optimizing electrode cap welding. Background technique [0002] Electrode cap is a kind of welding electrode, which is used for the welding of resistance welding equipment, such as fixed spot welder, suspension spot welder and manipulator spot welder. Because it is sleeved on the electrode connecting rod, it is called electrode cap. Most of the materials are chromium zirconium copper, and there are also dispersed copper. After a certain number of welding (usually 800-1000 points), it needs to be ground or replaced due to wear, which is a welding consumable part; [0003] In the prior art, the welding parameter setting of the spot welding robot is unreasonable, resulting in a short service life of the current electrode cap, and it is impossible to monitor the use process of the electrode cap in real time to ensure the quality of welding. SUMMARY OF THE INVENTION ...

AI Technical Summary

Problems solved by technology

After welding for a certain number of times (generally 800-1000 points), it needs to be ground or replaced due to wear and tear, which belongs to welding consumable parts;

[0003] In the prior art, the welding parameter setting of the spot welding robot is unreasonable, which leads to the short service life of the current electrode cap, and it is impossible to monitor the use process of the electrode cap in real time to ensure the quality of welding
