DCDC power supply module test system

Abstract

The invention relates to a DCDC power supply module test system. The DCDC power supply module test system comprises a positioning tool used for placing a DCDC power supply module, an auxiliary tool arranged on one side of the positioning tool, a feeding and discharging manipulator arranged on the auxiliary tool, a feeding and discharging suction head arranged at the front end of the feeding and discharging manipulator and used for replacing the DCDC power supply module to be tested, a bottom adsorption head arranged below the positioning tool and used for adsorbing or taking out the DCDC powersupply module, a detection device arranged on the auxiliary tool, a front positioning manipulator arranged on the auxiliary tool and located at the front end of the positioning tool, a front measuring head arranged at the front end of the front positioning manipulator, and a measuring probe arranged at the front end of the front measuring head and used for being in electric contact with the DCDCpower supply module. The DCDC power supply module test system is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a DCDC power module testing system. Background technique [0002] At present, the system and method for testing the output voltage of the DCDC module power supply with a special connector in the past is a simple connection test, and its test accuracy is low, because no matter how small the contact resistance of the connector is, a voltage drop will occur under high current Phenomenon, this error is unacceptable for high-precision testing. The significance of the method of the present invention is that the power and voltage signals are divided into two circuits, the power part still uses the traditional connector terminals, and an additional set of spring probes is added to test the module output pins. Since the actual current generated by the test voltage of the multimeter is extremely small, the contact resistance of the spring probe is also extremely small, so the voltage drop generated can be ignored, which effectively impr...

Problems solved by technology

In the traditional method, due to the point contact between the alligator clip and the converter pin, it is very easy to cause damage to the converter or "soft breakdown" of the internal circuit due to poor contact of the clip, which greatly increases the probability of human error and product scrapping. resulting in a sharp increase in production costs

Although CN201520454637.8 provides a set of solutions for a full-scale series of DC-DC converter dedicated test benches, its detection accuracy is still not high enough, and it is still not suitable for high-tech applications such as aerospace remote control, inertial navigation systems, and deep-sea exploration. field

[0003] In addition, the existing testing technology relies heavily on labor, which is costly, easy to cause product damage due to mistesting, and poses certain dangers to operators

Testing with electrodes held by people is not only easy to be hit by high voltage, but also more likely to cause internal breakdown of the module due to accidental touch
