When the pump of PVD vacuum coating machine works under extreme conditions
When the pump of the PVD vacuum coating machine works under extreme conditions, a strong violent noise occurs due to physical action (cavitation) in the pump, which will not cause great damage to the pump in a short time, and the power consumption is not Will increase, but long-term operation under this condition will cause serious damage to the internal parts of the pump, and sometimes even break the blades and shaft. Therefore, try to avoid long-term operation under extreme conditions.
Vacuum coating is an important aspect of the vacuum application field. It is based on vacuum technology, uses physical or chemical methods, and absorbs a series of new technologies such as electron beam, molecular beam, ion beam, plasma beam, radio frequency and magnetron. Scientific research and actual production provide a new process for film preparation. Simply put, the method of evaporating or sputtering metals, alloys or compounds in a vacuum to solidify and deposit them on the coated object is called vacuum coating.
When the existing vacuum coating machine coats the workpiece, the interior needs to be vacuumed and heated to a certain temperature. During continuous coating operation, the staff needs to turn on the vacuum coating machine to pick and place the workpiece. This operation has certain safety hazards , The stability is poor; when the vacuum coating machine is turned on, the internal vacuum environment will disappear, and the heat will escape, resulting in a waste of energy and increasing production costs.
Technology realization factors:
The purpose of this utility model is to solve the problem of poor stability when picking and placing workpieces in the prior art, and proposes a safe, reliable and highly stable vacuum coating machine.
In order to achieve the above purpose, the present utility model adopts the following technical solutions:
A vacuum coating machine with high stability, comprising a housing, the upper end of the housing is fixedly connected with a motor, a vertical baffle is arranged in the housing, and a gasket is arranged on the inner bottom surface of the housing, The gasket is made of silicone rubber material, the upper end of the baffle is fixedly connected with the inner side wall of the shell, the baffle divides the inside of the shell into a vacuum chamber and a heat treatment chamber, and the baffle is provided with a lower end A sliding groove provided with an opening, a sliding plate is slidably connected in the sliding groove, a threaded rod is connected to the internal thread of the sliding plate, and the upper end of the threaded rod sequentially penetrates the sliding plate, the baffle and the housing and extends to the outside of the housing. , The output shaft of the upper motor of the threaded rod is fixedly connected, the upper side wall of the vacuum chamber is provided with an opening, and the side wall of the opening is provided with a sealing mechanism for sealing the opening, and the sealing mechanism includes The cover plate above the opening, one end of the cover plate is hinged with the side wall of the opening through a hinge, the side wall of the opening is provided with a step matching the sealing plate, the vacuum chamber is provided with a working plate, so The working plate is fixedly connected to the side wall of the vacuum chamber through a pushing mechanism. The pushing mechanism includes a cylindrical shell fixedly connected to the side wall of the vacuum chamber. The inner side wall of the cylindrical shell is fixedly connected with an air bag. One end of the airbag is fixedly connected with a push rod, the push rod is slidably connected with the inner side wall of the cylindrical shell, and the end of the push rod away from the airbag extends to the outside of the cylindrical shell and is fixedly connected with the working plate. A cooling water pipe is provided, and the cooling water pipe sequentially penetrates the cylindrical shell and the shell and extends to the outside of the shell.
