Description

Technical Field

[0001] The present invention relates to the technical field of vacuum coating, in particular to a vacuum coating fixture and vacuum coating equipment. Background Art

[0002] At present, vacuum coating refers to a method of heating metal or non-metal materials under high vacuum conditions to evaporate and condense them on the surface of the coated part (metal, semiconductor or insulator) to form a thin film. The vacuum coating device includes a coating chamber, the bottom of the coating chamber is fixedly connected to a driving mechanism, the driving mechanism is connected to a turntable at the bottom of the coating chamber and drives the turntable to rotate, a vacuum coating fixture is fixed on the turntable, and a workpiece is fixed on the fixture, so that the workpiece rotates in the vacuum coating chamber to be fully coated. When using vacuum coating to prepare high corrosion-resistant coating fastener products, in order to ensure the uniformity and integrity of the corrosion-resistant coating on the surface of the fastener, it is necessary to ensure that the surface of the fastener substrate is exposed without overlap or obstruction during the coating process, which requires the fastener product to be suspended in a single piece in the coating furnace.

[0003] The prior art authorization announcement number is CN111041444B, which is a vacuum coating fixture and vacuum coating equipment, including a workpiece hanger and a hanger mounting seat; the workpiece hangers are provided with more than two, and a workpiece hanging structure is provided on them, and the workpiece hanging structure is used to hang the workpiece to be coated; the hanger mounting seat is used to be fixed to the furnace chamber of the vacuum coating machine; the hanger mounting seat is provided with a hanger pick-up and placement structure, and the hanger pick-up and placement structure allows the workpiece hanger to be detachably connected so that the workpiece hanger can be taken out and put into the furnace chamber. The vacuum coating fixture provided by the present invention can be placed outside the furnace door during the coating operation. The workpiece is mounted on the workpiece mounting structure, and then the workpiece hanger is installed as a whole on the hanger mounting seat in the furnace chamber. After the coating is completed, the workpiece hanger is removed as a whole and replaced with another batch of workpiece hangers, thereby enabling alternating production of different batches of workpieces and improving the efficiency of vacuum coating. However, the mounting seat of the invention rotates as a whole, but the workpiece hanger does not rotate, which may result in a good coating effect on the side facing the coating device and a poor coating effect on the side facing away from the coating device, requiring rework for secondary coating, which reduces the coating efficiency and affects product quality.
