焊接頭問題處理:無安全地鎖信號(中英)

表現:

Manifestation:


焊接槍與工件接觸時,檢測頁【安全地鎖信號】顯示為灰色

When the welding gun is in contact with the workpiece, the inspection page [Safety locksignal] is grayed out


原因分析:

Cause analysis:


  焊接槍與工件接觸時,信號接口一的5/6腳應導通狀態,當出現斷路或主板內部問題,則顯示為灰色,結構如下圖

When the welding gun is in contact with the workpiece, the 5/6 pin of the signal interface should be in the conduction state, and when there is an open circuit or internal problems of the motherboard, it is displayed in gray, and the structure is shown as follows


邏輯

logic


5腳連到安全地鎖夾頭,與工件接觸

The 5-pin is connected to the safety lock chuck and is in contact with the workpiece


6腳通過三芯線連接到焊接槍槍頭

The 6-pin is connected to the welding gun tip by a three-core wire



故障處理:

Troubleshooting :


1、同時測試扳機信號是否正常,個別情況為航空插口松動,會導致兩個信號都沒有,航插位于焊接槍的線往后80cm處

At the same time, test whether the trigger signal is normal, in some cases, the aviation socket is loose, which will lead to no two signals, and the aviation insert is located 80cm behind the line of the welding gun


2、直接短接信號接口一的5/6腳,如導通則主板沒問題,繼續下一步的檢查

Directly shortconnect the 5/6 pin of the signal interface one, if the conduction is fine, the motherboard is fine, continue to the next step of inspection


3、測量安全地鎖夾子到5腳的通斷

Measure the on-off of the safety lock clip to 5 feet


4、測量銅嘴到6腳的通斷,個別情況為線斷了,可使用萬用表測量信號通斷

Measure the onoff of the copper nozzle to 6 feet, in some cases, the line is broken, and the signal can be measured on and off with a multimeter
