Manufacturing method of DC magnetron sputtering power supply
The DC magnetron sputtering power supply works in the high frequency conversion mode. The DC output and the adjustment of the power supply current are realized by changing the pulse width of the high frequency conversion. Then, let's learn about the production method of the DC magnetron sputtering power supply!
In the conventional DC magnetron sputtering power supply casing technology, when assembling the DC magnetron sputtering power supply casing, it is necessary to combine screws and nuts for fixing. If it needs to be disassembled after fixing, it is necessary to rotate the nut to loosen it. For example, when cleaning the heat dissipation cover panel, many screws need to be removed. In addition, dust is easy to accumulate on the heat dissipation cover and needs to be installed and removed repeatedly. In this way, the screws are prone to defects after multiple rotations. A factor that makes it difficult to rotate
The purpose of the present invention is to combine and fix the screws and nuts when assembling the housing of the DC magnetron sputtering power supply proposed in the background art. For example, when cleaning the heat sink panel, you need to remove many screws. In addition, the heat sink mask is easy to accumulate dust and needs to be installed and removed repeatedly. In this way, the screws are prone to notches after multiple rotations. On the other hand, The force method is difficult to rotate
In order to achieve the above purpose, the present utility model provides the following technical solutions.
An easy-to-assemble DC magnetron sputtering power supply housing, which is characterized by having a housing with the front end fixed on the front panel with screws and the rear end fixed on the back panel with screws, and a suction cover fixed on the front with screws. The front panel at the position near the center of the front end of the panel is provided with a touch control panel under the suction cover. The touch control panel is fixed by a slot inside the housing, and the touch control panel is electrically connected to the power supply. The left side of the cooling water outlet and the outer surface of the rear end of the back plate are provided with a cooling water inlet. The cooling water outlet and the cooling water inlet are connected with the copper nozzle of the internal heat dissipation water cooling plate, and the cooling water outlet is provided on the upper right side of the cooling water outlet. The output terminal is fixedly connected to the outer surface of the back plate via a card slot inside the housing. A 4-core input socket is provided on the right side of the output terminal, and the 4-core input socket passes through a card inside the housing. The groove is fixedly connected to the outer surface of the back plate
Preferably, the movable device includes a hinge, the left and right ends of the outer surface of the front end of which are connected to one end of the hinge by screw fixing, and the other end is also connected to the outer surface of the rear end of the back panel by screw fixing to fix the curved shell. The left and right ends of the outer surface are fixed by screw threads and can be rotated relative to the back plate based on hinges. The central part of the heat dissipation cover is fixed at the lower end and is provided with a pin under the fixed curved shell. The spring key is fixed to the back panel by welding. On the outer surface of the rear panel, the fixed curved shell and the spring key are in the same longitudinal direction, and the fixed rod inside the spring key can move up and down inside the spring key. In order to facilitate the cleaning of the heat dissipation cover, hinges and pins are used , A movable device for fixing the curved shell. Use a hinge, one end of the hinge is fixed on the surface of the back panel with a screw, and the other end is also fixed with a screw to fix the heat sink. That is to say, the heat dissipation cover can be rotated relative to the back panel based on the hinge when in use, and when it is rotated to a certain angle, the rear end of the heat dissipation cover can be cleaned with a brush, thereby making it easier to clean. No time-consuming disassembly of fixing parts such as screws is required. When fixing the heat dissipation cover after cleaning, the lower end of the pin is inserted into the inside of the fixed curved shell to fix the heat dissipation cover. The fixing method has a simple structure, and is pressed into the fixed curved shell by the gravity of the fixed rod inside the pin, which is more practical.
The above is the production method of DC magnetron sputtering power supply. If you need to know more, please feel free to contact us!
