Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating, in particular to an online appearance detection device for vacuum coating. Background Art

[0002] With the improvement of vacuum coating technology and its wide application, the demand for coating is growing day by day. However, for some special-shaped workpieces, due to their structure, some concave and convex positions in the coating process are prone to uneven coating surface or too thin or too thick coating thickness. Therefore, it is necessary to inspect the appearance of the vacuum surface of the workpiece.

[0003] The Chinese authorized announcement number is CN 212871648 U. A detection mechanism for a vacuum coating device is provided. By setting a pressure sensor and a spring, this setting cooperates with the fixed connection between the pressure sensor and the piston plate, the sliding connection between the piston plate and the detection box, and the elastic force of the spring on the slider. When the device is used, the sealing of the device connection is detected, which facilitates the troubleshooting of the problem that the device cannot be used normally due to poor sealing of the connection.

[0004] However, this patent still has certain shortcomings when used. The existing method of inspecting the workpieces undergoing vacuum coating is to observe them with the naked eye by the operator. This inspection process is very cumbersome and time-consuming. The entire inspection process requires a lot of time and energy, and the inspection efficiency and accuracy are not high. In addition, for some coated workpieces with thick thickness requirements and long coating time, if the coating defects cannot be discovered during production, it is easy to cause huge economic losses.
