Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a vacuum coating machine which can uniformly coat a piston ring. Background Art

[0002] Vacuum coating machines primarily refer to a type of coating that requires a relatively high vacuum level. These include various types, including vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, and ion beam sputtering. The main concepts are categorized into two types: evaporation and sputtering. Therefore, a vacuum coating machine that can uniformly coat piston rings is required.

[0003] According to the description in a vacuum coating machine (authorization announcement number: CN216107178 U) disclosed in the patent website that can uniformly coat piston rings, "the utility model discloses a vacuum coating machine that can uniformly coat piston rings, including a coating machine barrel, a piston ring inlet pipe, an exhaust grid ring, an active disk and an ion beam pole. A piston ring inlet pipe is provided on the upper left side of the coating machine barrel, and an inner reinforcement cylinder is provided inside the coating machine barrel. After the piston ring to be coated enters the inner reinforcement cylinder, the staff presses a button switch to start the vacuum pump, and extracts the air in the inner reinforcement cylinder through the evacuation pipe. The extracted air is discharged from the exhaust grid ring, so that the environment in the inner reinforcement cylinder suddenly changes to a low-pressure vacuum state. At this time, magnetron sputtering is carried out through the ion beam pole. Under the low-pressure vacuum state, the piston ring to be coated is coated, which greatly improves the fit and smoothness of the film and the piston ring, reduces the incorporation of impurities in the air, and improves the efficiency of piston ring coating."

[0004] In response to the above description, the applicant believes that the following problems exist: a piston ring inlet pipe is provided on the left side above the coating machine barrel, and an inner reinforcement cylinder is provided inside the coating machine barrel. The bottom port of the piston ring inlet pipe is connected to the top of the inner reinforcement cylinder. The piston ring inlet pipe is in the shape of an inverted bucket. When the device places the workpiece for coating, the workpiece slides into the interior of the device through the pipe and cannot be fixed. The collision between the workpieces may affect the processing quality. Utility Model Content
