排除上述状况后,这时候先用万用表测量机器人电路板电源与地之间的阻值,通常机器人电路板的阻值不应小于70Ω。若阻值太小,才几或十几欧姆。说明机器人电路板上有元器件被击穿或部分击穿,就必须采取措施将被击穿的元器件找出来。

(注意!此时一定要搞清该板的工作电压的电压值与正负极性,不可接错和加入高于工作电压值。否则将对待修机器人电路板有伤害!老故障没排除,又增新毛病!用点温计测机器人电路板上各器件的温度,温度升的较快较高的视为重点怀疑对象。若阻值正常后,再用万用表测量板上的阻容器件二、三极管,场效应管,以及拨段开关等元器件。其目的就是首先要确保被测量过的元器件是正常的。能用一般测试工具(如万用表等)解决的问题,就不要把它复杂化。

二、先外后内

使用进行检测时。如果情况允许,好是有一块与待修板一样的好机器人电路板作为参照。然后机器人维修使用测试仪的双棒VI曲线扫描功能对两块板进行好、坏对比测试。开始的对比测试点可以从机器人电路板的端口开始;然后由表及里,尤其是对电容器的对比测试。这可弥补万用表在线难以测出电容是否漏电的缺憾。

三、先易后难

使用进行检测时。为提高测试效果,在对机器人电路板进行在线功能测试前,应对被修板做一些技术处理,以尽量削弱各种干扰对测试过程中带来的影响。具体措施如下:

1.测试前的准备

将晶振短路(注意对四脚的晶振要搞清那两脚为信号输出脚,可短路此两脚。记住一般情况下另外两脚为电源脚,千万不可短接!!),对于大容量的电解电容器,也要焊下一脚使其开路。因为大容量电容的充放电同样也会带来干扰。

After the above conditions are eliminated, at this time, use a multimeter to measure the resistance between the power supply and ground of the robot circuit board. Generally, the resistance of the robot circuit board should not be less than 70 Ω. If the resistance is too small, it is only a few or more ohms. It shows that if the components on the robot circuit board are broken down or partially broken down, measures must be taken to find the broken down components.
(note! At this time, be sure to make clear the voltage value and positive and negative polarity of the working voltage of the board, and do not connect wrongly or add higher than the working voltage value. Otherwise, the robot circuit board to be repaired will be damaged! The old faults have not been eliminated, and new faults will be added! Use a dot thermometer to measure the temperature of each device on the robot circuit board, and the one with a faster and higher temperature rise will be regarded as the key suspect. If the resistance value is normal, use a multimeter to measure the resistance and capacitance devices II and III on the board Transistor, FET, and toggle switch and other components. The purpose is to ensure that the measured components are normal. Don't complicate problems that can be solved with general testing tools (such as multimeter, etc.).
2、 From outside to inside
When using for detection. If circumstances permit, it is best to have a good robot circuit board as the same as the board to be repaired as a reference. Then the robot maintenance uses the dual bar VI curve scanning function of the tester to conduct a good and bad comparison test on the two boards. The starting comparative test point can start from the port of the robot circuit board; Then from the outside to the inside, especially the comparative test of capacitors. This can make up for the defect that it is difficult for the multimeter to detect whether the capacitor is leaking electricity online.
3、 Easy before difficult
When using for detection. In order to improve the test effect, some technical treatment should be done to the repaired board before the online function test of the robot circuit board, so as to minimize the impact of various interferences on the test process. Specific measures are as follows:
1. Preparation before test
Short circuit the crystal oscillator (note that for the four pin crystal oscillator, make sure that the two pins are signal output pins, and short circuit these two pins. Remember that the other two pins are power pins in general, and do not short circuit!!), For large capacity electrolytic capacitors, it is also necessary to weld the next leg to make it open circuit. Because the charge and discharge of large capacity capacitors will also bring interference.
