焊接頭問題處理:出氣不出光(中英)

表現:

Manifestation:


  焊接狀態時,扣動扳機后,出氣送絲,紅光正??梢?,但是不出激光

In the welding state, after pulling the trigger, the gas is fed, and the red light is normally visible, but the laser is not out


原因分析:

Cause analysis:


  邏輯上,當出氣時,出光信號也會發出去的,當激光器未收到出光信號(端口故障)或激光器有問題時

Logically, when the gas is out, the light signal is also emitted, when the laser does not receive the light signal (port failure) or there is a problem with the laser


解決方案

solution


①首先排除激光器本身存在報警,請注意,激光器電壓不穩定時也會不出光也不報警

(1) First of all, exclude the alarm of the laser itself, please note that when the laser voltage is unstable, it will not produce light or alarm


②凡是涉及到關機重啟后正常的,多數可能是激光器本身的可復位報警,建議聯系激光器廠家或者監控看下內部報警

(2) Where it is normal after shutdown and restart, most of them may be resettable alarms of the laser itself, it is recommended to contact the laser manufacturer or monitor the internal alarm


③針對激光器的觸發信號,兩種方案來測試

(3) For the trigger signal of the laser, two schemes to test


最簡單就是鏈接激光器的監控軟件,來查看缺失哪個信號。

另外可以測量信號接口三的信號口

通常,激光器只有收到使能/PWM/模擬量信號才會出光。

The simplest is to link the laser's monitoring software to see which signal is missing. In addition, the signal port of signal interface three can be measured

Typically, lasers emit light only when they receive an enable/PWM/analog signal.


因此,我們可以在【工作狀態下,即出氣or出絲】或者使用【診斷功能,獨立打開使能/PWM/模擬量】,然后測量信號是否發出來

Therefore, we can use [working state, that is, air outlet or wire out] or use [diagnostic function, independently turn on enable/PWM/analog], and then measure whether the signal is sent



(測量時請務必拔掉信號接口三的各端口上激光器的線,如圖所示

(When measuring, be sure to unplug the laser wire on each port of signal interface three, as shown in the figure)


使能信號:2/4腳 24V

Enable signal: 2/4 pin 24V


PWM調制解調信號:6/7腳 24V

PWM modulation and demodulation signal: 6/7 pin 24V


模擬量信號:4/5腳 等比例電壓,滿功率下有10V

Analog signal: 4/5 pin equal proportional voltage, 10V at full power


如果以上信號正常,依舊不出光,則聯系激光器廠家處理

If the above signal is normal and still does not produce light, contact the laser manufacturer for processing


如使能/PWM其中一個沒電壓,可以放在一起使用,如PWM接使能信號腳

If one of the enable/PWM is not voltage, it can be put together, such as PWM connected to the enable signal pin


如模擬量沒有電壓,且紅光是一條線,返廠維修或更換主板

If there is no voltage in the analog quantity, and the red light is a line, return to the factory for repair or replace the motherboard


如模擬量沒有電壓,且紅光是一個點,則檢查15V開關電源±是不是接反了

If there is no voltage in the analog quantity and the red light is a point, check whether the 15V switching power supply ± is reversed
