Description

Technical Field

[0001] This application relates to the field of coating equipment, and more specifically to an upper clamping assembly used in a vacuum coating process in a vertical coating line. Background Technology

[0002] In the double-sided vacuum coating process, the front and back sides of the product need to be coated sequentially or simultaneously.

[0003] In a horizontal continuous coating production line, one side is usually coated at a time, and the product clamping mechanism is relatively simple. However, when coating the other side, a large number of mechanical equipment are required to assist, which increases the usage time, reduces the work quality, and makes the product more susceptible to damage.

[0004] Unlike horizontal continuous coating single-sided production processes, vertical coating lines have more complex product clamping. As workpiece sizes increase, the size of the coating chamber cathode also increases. Existing fixing mechanisms often suffer from problems such as unstable clamping leading to coating shift, obscuring the coating area and affecting film integrity, or insufficient positioning accuracy during face changing causing misalignment of the two film layers. These issues seriously affect product coating quality and production efficiency. There is an urgent need for a stable, reliable, and precisely positioned fixing mechanism to solve these problems.
