Description

Technical Field

[0001] The utility model relates to the field of optical filter assembly equipment, in particular to an optical filter assembly equipment. Background Art

[0002] At present, there are two main methods of laminating oblique prisms: manual lamination and automatic lamination. Manual lamination requires the use of tweezers to clamp the filters one by one, which is inefficient and easy to damage and dirty the filters. For some automatic lamination machines, the filters need to be manually clamped into the fixture, which also has the problem of low efficiency of manually laminating one by one.

[0003] Furthermore, when certain filters are plasma treated, the filter bonding surface needs to face upward and be plasma treated, thereby facilitating the loading of adhesives or coating layers.

[0004] However, when the filter needs to be bonded to the rhombus prism, the plasma side needs to face downwards to achieve bonding. Due to the small structure of the rhombus prism, the existing automated equipment structure is relatively complex and the production cost is relatively high. Utility Model Content

[0010] The technical solution of the utility model realizes the material arrangement of the filter through the long strip-shaped loading seat in the feeding device of the filter, and a plasma processing device can be arranged above the loading seat to realize the plasma processing of the filter. When the filter at the front end of the loading seat moves to the position of the notch, the adsorption hole of the notch fixes the filter through negative pressure, and then the swing seat drives the filter to flip to the position above the attachment surface of the rhombus prism, and the rhombus prism is driven by the vertical adjustment device to rise and connect with the filter, thereby realizing the filter assembly of the rhombus prism.
