Problems solved by technology

[0004] The original manual detection method needs to manually connect the probe to the test pin, and then connect the test system. This test method has low work efficiency, high labor intensity, and is prone to human detection errors. In addition, the test data needs to be recorded manually. Prone to errors, etc., unable to meet mass production and increasingly stringent quality control requirements, low production efficiency, prone to missed inspections, wrong inspections

Abstract

The invention discloses an automatic testing device for IGBT (Insulated Gate Bipolar Transistor) modules, and relates to the technical field of automatic IGBT module testing. The automatic testing device comprises a feeding system, a material carrying system, a camera positioning system, a testing system and a two-dimensional code scanning system. Feeding trays are installed on the left side and the right side, testing cannot be interrupted due to feeding; grabbing of modules of different sizes and specifications in batches can be achieved, and the requirements for various models and differentsizes in actual production are met; operators can operate the device without special training, the modules do not need to be accurately placed, and the fault tolerance is high; a camera installed atthe bottom of the device accurately positions the position of the modules, and a robot can achieve high-precision placement according to the position and deviation angle, shot by the camera, of the module; a test tray is rotatable, so that uninterrupted test is realized; and a two-dimensional code reading system is installed so that whole-course traceability of test data can be realized.

Description

technical field [0001] The invention belongs to the technical field of power semiconductor device testing, in particular to an IGBT automatic testing device. Background technique [0002] IGBT (Insulated Gate Bipolar Transistor) is a composite fully-controlled voltage-driven power semiconductor device with high frequency, high voltage, high current, and easy switching. The IGBT module is a modular semiconductor product that is packaged by IGBT and FWD (freewheeling diode chip) through a specific circuit bridge. The IGBT module has the characteristics of energy saving, convenient installation and maintenance, and stable heat dissipation; For such modular products. With the advancement of concepts such as energy saving and environmental protection, such products are widely used in rail transit, smart grid, aerospace, electric vehicles and new energy equipment. [0003] In recent years, with the continuous development of electric vehicles, high-speed rail and power electronic...
