AI Technical Summary
In the existing technology, manual assembly during the heat sink assembly process cannot meet the requirements of the adhesive properties, resulting in insufficient adhesive adhesion and increasing the risk of the heat sink falling off.
Design an automatic pressure-holding device that uses a pressure sensor and a silicone contact layer, combined with a lifting drive and elastic components, to ensure that the set pressure is maintained at a fixed level and to reduce product deformation.
The adhesive strength of the radiator backing was improved, reducing the risk of the radiator falling off, decreasing employee fatigue, and increasing assembly efficiency.
