AI Technical Summary
In existing press-fit IGBT clamping fixtures, the weakening of the spring force of the clamping components leads to unstable clamping force, affecting the clamping consistency of the modules and the reliability of product quality.
Synchronous components are used to achieve synchronous movement of the clamping components, and the spring force is dynamically adjusted through the coordinated cooperation of the positioning component and the drive component to enhance the elastic recovery capability and extend the service life.
It effectively avoids clamping deviation, improves clamping reliability and ease of operation, and extends the service life of the equipment.
