Embodiment Construction

[0018] The present invention will be further described below with reference to the specific drawings and embodiments.

[0019] like figure 1 , figure 2 , image 3 As shown, the embodiment of the present invention proposes a device for automatically detecting the starting point and end point of lap welding welding of metal parts, including: an auxiliary power supply 1, a relay 2, and a PLC controller 3; wherein the auxiliary power supply 1, the relay 2, the welding part 4. The workpiece 9 forms a small loop, the relay 2, the PLC controller 3, and the welding machine main body 5 form a large loop, and the PLC controller 3 can control the welding machine main body 5 to perform actions.

[0020] The PLC controller 3 can collect the signal that the relay 2 is closed or disconnected, so as to control the main body 5 of the welding machine to walk and perform welding.

[0021] Auxiliary power supply 1 is a regulated DC power supply that can be 12V, 24V, and 36V, with low power co...

Abstract

The invention provides a device for automatically detecting a starting point and an ending point of lap seam welding of a metal part. The device comprises an auxiliary power supply, a relay and a PLC,wherein the auxiliary power supply, the relay, a welding part and the workpiece form a small loop, when the welding part is in contact with the workpiece, the small loop is closed, the PLC detects the starting point and controls a welding machine main body to perform welding, when the welding part is separated from the workpiece, the small loop is disconnected, the PLC detects the ending point and controls the welding machine main body to stop welding. The device is advantaged in that problems that the traditional welding process is long in time and low in efficiency, and full welding cannotbe guaranteed are solved.

Description

technical field [0001] The invention relates to the technical field of welding detection, in particular to a device for automatically detecting the starting point and end point of lap welding welding of metal parts. Background technique [0002] Seam welding is a resistance welding method in which the weldments are assembled into lap joints or oblique butt joints and placed between two roller electrodes. Traditional resistance welding equipment often needs to stop during the welding process for inspection to check the welding quality and whether it is fully welded, resulting in long welding time and low efficiency. . SUMMARY OF THE INVENTION [0003] In view of the deficiencies in the prior art, the present invention provides a device for automatically detecting the starting point and end point of lap welding welding of metal parts, which solves the problems of long welding process time, low efficiency, and inability to guarantee full welding. By using an auxiliary power ...
