Description

Technical Field

[0001] The utility model relates to a coating device, belonging to the field of optical glass processing equipment. Background Art

[0002] Optical glass lenses need to be coated during the processing. A vacuum coating machine is usually used for coating optical glass lenses. Inlet and outlet are opened on two parallel sides of the vacuum coating machine. Sealing doors for sealing the inlet and outlet are installed inside the inlet and outlet. When the optical glass is transferred to the support in the vacuum chamber through the transmission line, the inlet and outlet and the sealing door have a certain width. Therefore, when one end of the optical glass is between the inlet and outlet and the sealing door, it is easy to tilt downward due to lack of support, thereby pressing against the support in the vacuum chamber, resulting in poor transmission of the optical glass. Therefore, it is necessary to design a coating equipment that can prevent the optical glass from getting stuck when entering and exiting the vacuum chamber. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a coating device to solve the problems raised in the above-mentioned background technology. The utility model prevents optical glass from getting stuck when entering and exiting a vacuum chamber.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a coating device, including a bottom box, a vacuum chamber is installed on the upper end of the bottom box, a bracket for holding up optical glass is installed at the inner bottom of the vacuum chamber, a support for reducing the resistance to movement of optical glass is installed on the lower surface of the bracket, inlet and outlet are provided on two parallel sides of the vacuum chamber, sealing doors for blocking the inlet and outlet are provided on the inner sides of the two inlet and outlet, two notches are symmetrically provided on the upper surface of the bracket, the sealing door passes through the notches, a horizontally arranged connecting plate is provided on the lower side of the bracket, the two ends of the connecting plate are respectively connected and fixed to the two sealing doors, a vertically arranged electric push rod is installed in the middle position of the lower surface of the connecting plate, the cylinder end of the electric push rod is installed at the bottom of the bottom box, and a plurality of first bull's eyes for holding up optical glass are evenly installed on the upper surface of the sealing door.

[0010] Beneficial effects of the utility model:

[0011] 1. Control the extension and retraction of the electric push rod, which drives the sealing door to move, so that the sealing door can block or open the inlet and outlet. When the inlet and outlet are in the open state, the first bull's eye installed on the upper end of the sealing door is flush with the second bull's eye, so that the first bull's eye facilitates the smooth movement of the optical glass from the conveyor line to the bracket, avoiding the optical glass from hitting the second bull's eye due to uneven force during the process of passing through the sealing door, thereby realizing the smooth transmission of the optical glass.

[0012] 2. Insert the plug on the first bull's eye into the slot, and then screw the connecting screw through the countersunk hole into the screw hole to complete the assembly of the plug and the sealing door. There is no need to process screw holes on the sealing door to match the connecting screws. When the screw holes are damaged due to wrong threads or other reasons, just replace the corresponding first bull's eye without replacing the sealing door.

[0013] 3. When the electric push rod is in a retracted state, the magnet block is not adsorbed to the iron plate. Under the action of the spring, the ball part of the second bull's eye is exposed on the upper side of the circular groove, so that the second bull's eye cooperates with the first bull's eye to transfer the optical glass to the bracket. After the electric push rod is controlled to extend, the sealing door seals the inlet and outlet. At this time, the magnet block and the iron plate are adsorbed to each other, so that the iron plate moves downward. The iron plate drives the second bull's eye to move downward through the column rod, so that the second bull's eye is retracted into the circular groove, which is convenient for the optical glass to fit on the bracket. After evacuating the vacuum chamber, the coating operation can be carried out. BRIEF DESCRIPTION OF THE DRAWINGS
