Description

Technical Field

[0001] This utility model relates to the technical field of power device testing equipment, specifically a power device testing device. Background Technology

[0002] Power device testing equipment is used to test the electrical performance of power semiconductor devices (such as transistors, MOSFETs, IGBTs, etc.). This equipment typically consists of a test bench, testing instruments, a controller, and a power supply. It can test parameters such as current, voltage, power, and frequency of power devices and provide high-precision, high-speed, and high-reliability test results. Power device testing equipment is widely used in power electronics, transportation, industrial automation, and communication equipment, and is an important tool for ensuring the quality and reliability of power devices. After the production of power devices is completed, each device needs to undergo polarity withstand voltage and insulation testing using a power device testing equipment.

[0003] In existing technologies, to improve production efficiency, multiple power devices are manually laid side by side on a test bench for simultaneous testing. Although this eliminates the need for frequent start-ups of the test device, the manual assembly and disassembly of the power devices is still cumbersome, reducing testing efficiency. Furthermore, the testing range of the test device is limited, and the distance between the test end and the power device test device cannot be quickly and automatically adjusted according to the size of the power device, thus narrowing the detection range of the test device. Therefore, we propose a power device test device. Utility Model Content

[0030] Working principle: The conveyor drive motor 4 starts, driving the transmission shaft 3 to rotate.

The conveyor belt 15 transports the power device to the test position. According to the size of the power device, the correction adjustment cylinder 7 on the correction support platform 21 operates, pushing the correction push rod 18 to move.

Through the action of the correction slide plate 17, the power device is corrected to a suitable test position, ready for testing. The transverse drive motor 12 starts, driving the transverse drive screw 11 to rotate. The transverse slider 10 is guided through the top sliding groove 20. Meanwhile, since the transverse threaded hole 19 is threadedly connected to the transverse drive screw 11, the rotation of the transverse drive screw 11 causes the transverse slider 10 to move laterally on the top support platform 16, driving the power transmission test assembly to move laterally above the power device to be tested. After the transverse slider 10 moves into position, the lifting drive cylinder 13 works, pushing the lifting drive push rod 14 to move downward. The lifting drive push rod 14 drives the lifting push plate 9 to move downward, thereby causing the power transmission platform 6 to descend. The power transmission platform 6 contacts the power device, and at the same time, the power transmission platform 6 and the electrode transmission platform 8 are started to supply power to the power device for insulation performance and other tests. Through the cooperation of the test assembly and the transmission assembly, the fully automatic detection of the power device is realized, improving the testing efficiency.
