Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens production equipment, and in particular relates to a glass cleaning mechanism for an optical lens ion source coating machine. Background Art

[0002] Modern optical lenses (such as glass lenses) are typically coated with single or multiple layers of antireflection coating to reduce reflection and increase light transmittance. Existing technology often uses ion source coating machines for coating glass lenses. Patent document CN2690417Y discloses a planar ion source enhanced deposition coating machine, which includes a vacuum system, a heating system, a bias system, a gas supply system, a workpiece transmission mechanism, a planar ion source, and a metal sputtering evaporation source such as magnetron sputtering or multi-arc. The planar ion source consists of an internal anode, a slit cathode, a magnetic field, a cathode shield, and a gas circuit. Under certain vacuum conditions, gas ions with a certain energy are generated to clean the workpiece surface. These ions then react with metal ions generated by the metal evaporation source to deposit a highly adhesive thin film on the workpiece surface. While this patent allows for coating operations, it does not allow for cleaning of the workpiece (glass lens) before coating. If impurities are present on the glass lens, this can affect the coating effect and hinder production. Therefore, a glass cleaning mechanism for an optical lens ion source coating machine is needed to address the aforementioned technical issues. Utility Model Content

[0031] Working principle: Install the glass lenses to be cleaned on the mounting holes on the carrier plate, then place it on the operating platform. The forward and reverse motors drive the support rods to rotate, moving the mechanical claws to the top of the carrier plate. The vertical telescopic rods extend, and the mechanical claws move down to the carrier plate. The forward and reverse motors rotate three times, and the two clamping claws move toward each other to clamp the carrier plate (such as Figure 1 、 Figure 2 As shown), the vertical telescopic rod is retracted, driving the carrying plate to move up, and then the forward and reverse motor 1 rotates in the opposite direction to move the carrying plate to the top of the cleaning box, and then the forward and reverse motor 2 rotates to rotate the hinge shaft 90 degrees, so that the carrying plate changes from a horizontal state to a vertical state, and the vertical telescopic rod is extended to drive the carrying plate to move down into the cleaning box (as shown). Figure 5 As shown), at this time, the glass lenses on the carrier plate correspond to the air distribution pipe and the water distribution pipe, and the water spray head on the water distribution pipe sprays water to clean the glass lenses. Then the water spray head is closed and the air spray head is opened to air-dry the glass lenses. After the air-drying is completed, the vertical telescopic rod is retracted, and the carrier plate is taken out of the cleaning box. The forward and reverse motors continue to rotate to move the carrier plate to the top of the ion source coating machine feed port. Then the forward and reverse motors rotate 90 degrees in the opposite direction to restore the carrier plate to a horizontal state. The vertical telescopic rod is extended to place the carrier plate on the operating platform (as shown). Figure 6 As shown), finally enter the ion source coating machine to carry out the coating operation.
