Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically a PVD coating equipment. Background Technology

[0002] PVD, or Physical Vapor Deposition, refers to the process of transferring matter from a source to a substrate surface using physical processes. Its purpose is to allow certain microparticles with special properties to be sprayed onto a substrate with lower performance, thereby giving the substrate better performance. The basic methods of PVD are: vacuum evaporation, sputtering, and ion plating.

[0003] The patent application number "CN214300324U" describes "a novel PVD coating equipment, comprising a device body, a fixed plate at the bottom of the device body, a material storage trough at the top of the fixed plate, a rotating plate at the top of the device body, arc-shaped plates on both sides of the bottom of the rotating plate, an adjusting rod at the bottom of the arc-shaped plate, a clamping plate at one end of the adjusting rod, and a rotating shaft on both sides of the bottom of the fixed plate, with a cooling fan on the outer side of the top of the rotating shaft. This invention, through the arrangement of the clamping plate and the rotating plate, allows the hydraulic cylinder to adjust the distance between the two clamping plates, enabling the clamping plates to clamp and fix objects of different sizes. Simultaneously, a first motor drives the rotating plate to rotate, thereby rotating the object to be coated, resulting in a more uniform coating. A second motor drives two cooling fans to rotate, thereby dissipating heat from the heating plate."

[0004] The aforementioned patent can clamp and fix objects of different sizes, making the coating of the objects more uniform and dissipating heat from the heating plate. However, during use, the raw materials inside the storage tank are in a static state, which cannot guarantee uniform heating or evaporation. At the same time, it cannot control the internal airflow, affecting its use. Utility Model Content

By using a stirring mechanism, the raw materials can be flowed, ensuring uniform heating during heating and achieving the evaporation effect. This also improves production efficiency, reduces production costs, and ensures process stability.

The overall structure is simple, easy to use, and improves the overall performance.

The first stirring blade 13 and the second stirring blade 12 rotate in opposite directions to stir the raw materials inside the storage tank 17 to ensure their use. The top of the coating box 1 has a positioning device, which is existing technology and will not be described in detail here.
