Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5An optical lens coating device with a drying mechanism includes a base 001, a support seat 101 slidably connected to the upper end of the base 001, a plurality of placement slots 102 provided on the upper end of the support seat 101, an electric push rod 103 fixedly connected to the lower end of the base 001, the output end of the electric push rod 103 fixedly connected to the lower end of the support seat 101, a bracket 104 fixedly connected to the upper end of the base 001, columns 105 rotatably connected to both inner walls of the bracket 104, and a cover plate 108 slidably connected to the top of the bracket 104; and a housing 002 rotatably disposed on both inner walls of the bracket 104, the side walls of the housing 002 fixedly connected to the ends of the columns 105, and drying chambers 2 respectively provided inside both ends of the housing 002. The coating chamber 204 is located inside the housing 002. Multiple holes 203 are provided between the chamber 202 and the drying chamber 201. A coating emission device 205 is fixedly connected to the inner wall of the coating chamber 204. A vacuum pump 206 is fixedly connected to the side wall of the housing 002. The input end of the vacuum pump 206 communicates with the interior of the coating chamber 204. The lower edge of the cover plate 108 is arc-shaped. A sealing ring is provided on the upper end of the support seat 101. Before vacuum coating of the optical lenses, the operator places multiple optical lenses into the multiple placement slots 102 on the upper end of the support seat 101. Then, the output end of the electric push rod 103 pushes the support seat 101 upwards, sliding it into the drying chamber 201. The optical lens is located inside the drying chamber 201. Hot air is then supplied to the chamber 202 and ejected through multiple holes 203 onto the surface of the optical lens to dry it. After drying, the output end of the electric push rod 103 pulls the carrier 101 downwards, causing the optical lens to slide out of the drying chamber 201. Then, one of the pillars 105 rotates the housing 002 180°, positioning the coating chamber 204 above the carrier 101. The output end of the electric push rod 103 then pushes the carrier 101 upwards, sliding it into the coating chamber 204. At this point, the optical lens is in the coating chamber. Inside cavity 204, vacuum pump 206 is used to evacuate the inside of coating cavity 204. After the vacuuming is completed, vacuum pump 206 stops operating. Then coating emission device 205 operates and emits coating material to coat the surface of optical lens located inside coating cavity 204. When housing 002 rotates, the outer or inner wall of housing 002 contacts the arc-shaped side of cover plate 108. As housing 002 rotates, cover plate 108 is moved and slid. When drying cavity 201 or coating cavity 204 rotates upward, cover plate 108 automatically slides into drying cavity 201 or coating cavity 204, thereby sealing drying cavity 201 or coating cavity 204.
[0023] A motor 106 is fixedly connected to the side wall of the bracket 104. The output end of the motor 106 is fixedly connected to the end of one of the columns 105. Two guide rods 111 are slidably connected through the base 001. The upper end of the guide rod 111 is fixedly connected to the lower end of the support 101. The output end of the motor 106 drives one of the columns 105 to rotate. When the support 101 slides longitudinally, it is guided and assisted by the guide rod 111.
[0024] The upper end of the bracket 104 is slidably connected to two vertical rods 107. The lower end of the vertical rods 107 is fixedly connected to the upper end of the cover plate 108. A spring 109 is fixedly connected between the upper end of the cover plate 108 and the inner top of the bracket 104. A limit plate 110 is fixedly connected to the upper end of the vertical rods 107. When the cover plate 108 is pushed and slid by the housing 002, the spring 109 contracts. When the lower end of the cover plate 108 is separated from the side of the housing 002, the energy of the spring 109 is released and pushes the cover plate 108 to slide. The vertical rods 107 guide and assist the longitudinally sliding cover plate 108, while the limit plate 110 limits the sliding distance of the cover plate 108.
[0025] A pipe 207 is fixedly connected through the side wall of the shell 002, and the pipe 207 is connected to the chamber 202. A box 003 is fixedly connected to the side wall of the shell 002, and an air pump 301 is fixedly connected to the side wall of the box 003. The output end of the air pump 301 is connected to the inside of the box 003. The air pump 301 delivers external airflow to the inside of the box 003, and the airflow then flows to the inside of the chamber 202 through the pipe 207.
[0026] A filter screen 302 is fixedly connected inside the housing 003, and multiple heating wires 303 are fixedly connected inside the housing 003. The airflow flowing into the housing 003 is filtered and purified by the filter screen 302, and then the airflow is heated by the multiple heating wires 303.
[0027] The side wall of the housing 002 is provided with multiple heat dissipation holes 208, which are arranged in a ring array. The operator fixes the external filter plate inside the heat dissipation holes 208, and the hot air flow after drying the optical lens inside the drying chamber 201 is discharged through the multiple heat dissipation holes 208.
[0028] In this invention, before vacuum coating of optical lenses, the operator places multiple optical lenses inside multiple placement slots 102 at the upper end of the carrier 101. Then, the output end of the electric push rod 103 pushes the carrier 101 to slide upward, and the carrier 101 slides into the drying chamber 201. At this time, the optical lenses are located inside the drying chamber 201. Then, the external airflow is delivered to the chamber 003 by the air pump 301. The airflow flowing into the chamber 003 is filtered and purified by the filter screen 302. Then, multiple heating wires 303 heat the airflow. The hot airflow flows into the chamber 202 through the pipe 207. The hot airflow is then sprayed out onto the surface of the optical lenses through multiple holes 203 to dry the optical lenses.
[0029] After the optical lens is dried, the output end of the electric push rod 103 pulls the carrier 101 downward, causing the optical lens to slide out of the drying chamber 201. Then, the output end of the motor 106 drives one of the columns 105 to rotate, which in turn drives the housing 002 to rotate 180°, so that the coating chamber 204 is located above the carrier 101. Then, the output end of the electric push rod 103 pushes the carrier 101 upward, and the carrier 101 slides into the coating chamber 204. At this time, the optical lens is located inside the coating chamber 204. Then, the vacuum pump 206 operates to evacuate the coating chamber 204. After the vacuum is evacuated, the vacuum pump 206 stops operating. Then, the coating emission device 205 operates and emits coating material to coat the surface of the optical lens located inside the coating chamber 204.
[0030] When the housing 002 rotates, the outer or inner wall of the housing 002 contacts the arc-shaped side of the cover plate 108. As the housing 002 rotates, the cover plate 108 is pushed and slid, the spring 109 contracts, and when the lower end of the cover plate 108 disengages from the side of the housing 002, the energy of the spring 109 is released, and it pushes the cover plate 108 to slide. The cover plate 108 automatically slides into the drying chamber 201 or the coating chamber 204, thereby sealing the unused drying chamber 201 or coating chamber 204.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
