This utility model relates to the technical field of optical device coating equipment, and particularly to a coating fixture for an open-aperture lens. The open-aperture lens has a coating surface at one end along the axial direction and a positioning part at the other end. The open-aperture lens also has a through hole along the axial direction. The coating fixture includes a fixture body and a fixing member. A positioning groove is provided at the bottom of the fixture body, and a through hole communicating with the positioning groove is provided at the top of the fixture body. The positioning groove is used to position the positioning part. The fixing member passes through the through hole and the through hole in sequence. One end of the fixing member has a limiting part that can be engaged in the through hole, so that the positioning groove positions the positioning part. The coating fixture for the open-aperture lens provided by this utility model can reliably fix and accurately position the lens without obstructing the coating surface.

The utility model discloses a wave trap, including shell and be located in the inner shell of shell, fixedly connected with inner core and inductance coil on the inner shell, be equipped with the aperture unit for fixing inner core and inductance coil on the inner shell, form the cambered surface unit between aperture unit and the outer wall of inner shell, and aperture unit extends to the inside of inner shell and forms the convex unit, and aperture unit intercommunication cambered surface unit and convex unit. The utility model discloses reasonable structure design, and the aperture of inner shell side surface and bottom surface all adopt non - material punching process, and the aperture around convex circle forms convex unit, increases the interface of the component of interface, and the cambered surface unit is formed to the outside of aperture, forms the tin dissolving groove, makes tin not to flow to other position, guarantees that tin and the interface of component are covered well, thereby guarantees that the welding is good, and it is not easy to appear the phenomenon of false welding.

The invention discloses a positioning and trepanning jig for a lens frame of VR glasses and a positioning and trepanning method of the positioning and trepanning jig. The two reference cylinders are vertically arranged on the workbench, and the reference cylinders are movably arranged in the lens openings of the lens frame in a penetrating mode; the lower ends of the poking pieces are installed on the outer wall of the reference cylinder in a turnover mode, a plurality of penetrating holes are formed in the reference cylinder, the inner sides of the poking pieces are connected with supporting and ejecting rods, the supporting and ejecting rods movably penetrate through the penetrating holes, and elastic pieces are installed between the supporting and ejecting rods and the penetrating holes; a supporting plate is erected on the workbench, the supporting plate is arranged above the two reference cylinders, the supporting plate is provided with the extrusion part in a lifting mode, and the outer diameter of the extrusion part is gradually increased from bottom to top; the punching mechanism is installed on the bearing plate in a lifting mode, and the punching mechanism is aligned to the hole opening position of the lens frame. The lens frame punching device solves the problem that when a common positioning device is used for positioning a lens frame for punching, the punching position is not accurate.
