Abstract
A detection device includes a chamber for vacuum coating, a capacitance measurement device and a baffle mechanism located in the chamber. The baffle mechanism is a closed structure encompassed by a number of baffle walls, wherein at least one baffle wall includes a fixed baffle plate and a moveable baffle plate. The moveable baffle plate is pivotable about the fixed baffle plate. The moveable baffle plate, after pivoting, may get parallel with an adjacent baffle wall. The adjacent baffle wall and the moveable baffle plate are respectively connected to the capacitance measurement device, and the capacitance measurement device is used to measure the capacitance between the adjacent baffle wall and the moveable baffle plate. The detection device may accurately detect the service life of the baffle mechanism and achieve precise management of the apparatus.
