Description

TECHNICAL FIELD

[0002] With the increasing demand for heat dissipation performance of modern electronic equipment and industrial products, the connection quality between aluminum alloy die casting and heat sink is particularly important. Among them, brazing as a common connection process is widely used in the manufacture of such structures. For example, the patent with the publication number CN210498706U discloses a high-frequency brazing heat sink, which is composed of a die casting and a heat sink. The heat sink includes an extruded profile or a cold-forged component. The die casting and the heat sink are fixed to each other by brazing filler metal. The brazing filler metal is distributed at the edge position of the die casting and the heat sink, forming a sealed connection filler layer along the edge of the die casting and the heat sink. The existing brazing method is mostly operated by hand or semi-automatic equipment. First, spot welding is used to position the die casting and the heat sink, then clamping is performed, and full welding is carried out after clamping. However, there are defects such as complex clamping structure, inconvenient adjustment, poor adaptability, etc. Traditional clamps mostly use pneumatic or hydraulic clamping, which requires multiple independent drive units to control positioning elements in different directions. Not only is the cost high, but the control is also complex, making it difficult to achieve rapid synchronous positioning. After welding is completed, there are often defects such as welding beads and spatter at the weld, which need to be transferred to a polishing equipment for subsequent processing, increasing the transfer time and risk of collision between processes, which is not conducive to continuous production. More importantly, the existing equipment has single function, mostly only has welding capability, cannot integrate auxiliary processing functions such as polishing, drilling and stamping, resulting in a large number of types of production line equipment, large floor area and high maintenance cost, which is difficult to meet the demand for multi-process collaborative processing.
