Description

Technical Field

[0001] The utility model relates to the technical field of lens processing equipment, in particular to an adhesive coating device for optical lens processing. Background Art

[0002] Optical lenses are mostly installed in frames or special brackets during use. There are two main existing installation processes: one is to place the lens in the frame first and then perform ultrasonic welding, but this processing method requires high processing accuracy of mechanical equipment; the other is to apply glue to the inner arc of the frame, then place the lens, and finally cure it through curing equipment.

[0003] Although gluing lenses to frames does not require high processing equipment requirements, the amount of glue applied to the frame is difficult to control. Therefore, glue overflow is likely to occur at the joint between the two after the lenses are installed, requiring additional inspection and cleaning steps. Moreover, it is difficult and time-consuming to clean after the glue solidifies. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Example 1

[0019] Reference Figure 1 The utility model provides an adhesive coating device for optical lens processing, including a frame 1, a mounting plate 2 is arranged on the top of the frame 1, a pressurized glue barrel 9 is installed inside the frame 1, a bracket 5 is installed below the mounting plate 2, a servo motor (not shown) is arranged on the bracket 5, the output shaft of the servo motor passes through the mounting plate 2 from bottom to top and is installed with a lens support 6, and a detachable glue plate 7 is installed on the frame 1 below the lens support 6.

[0020] The frames 1 on both sides of the lens support 6 are symmetrically mounted with a gluing mechanism 3 and a material moving mechanism 4. The material moving mechanism 4 transfers the lenses on the conveyor belt 8 and presses them onto the lens support 6. The gluing mechanism 3 applies glue on the outer edge of the lenses.

[0021] Reference Figure 2 The material moving mechanism 4 includes a translation screw 401 fixedly mounted on the frame 1, a material moving bracket 402 is mounted on the slider of the translation screw 401, a lifting bracket 403 and a lifting cylinder 404 are mounted on the material moving bracket 402, wherein the lifting bracket 403 is slidably connected to the material moving bracket 402, the piston rod of the lifting cylinder 404 is connected to the top of the lifting bracket 403, three material moving support plates 405 are spaced apart on the top of the lifting bracket 403, a mirror pressing cylinder 406 is mounted on the middle one of the three material moving support plates 405, vacuum suction cups 407 are mounted on the material moving support plates 405 on both sides, and a soft pressing head is rotatably mounted on the piston rod of the mirror pressing cylinder 406.

[0022] During operation, the vacuum suction cup 407 adjacent to the conveyor belt 8 sucks the lens from it and is transferred to the lens support 6 driven by the translation screw 401. The support 6 is usually made of soft material to avoid scratching the mirror surface. After the mirror pressing cylinder 406 moves to face the lens support 6, its piston rod extends out, and the soft pressure head on it presses against the center of the upper surface of the lens, thereby fixing the lens on the lens support 6. The servo motor drives the lens support 6 to rotate the glue coating mechanism 3 to apply glue on the outer edge of the lens.

[0023] Reference Figure 3 The glue coating mechanism 3 includes a glue coating support plate 301, a feed slide rail 307 is installed on the glue support plate 301, a glue gun seat 302 is installed on the slider of the feed slide rail 307, two glue coating guns 304 are installed on the glue gun seat 302, a feed cylinder 303 is installed on the side of the glue coating support plate 301, the piston rod of the feed cylinder 303 is connected to the glue gun seat 302 to drive it to approach or move away from the lens support 6, and a double-headed glue discharge needle 305 and a single-headed glue discharge needle 306 are respectively installed on the discharge ports of the two glue coating guns 304, the two glue discharge ports of the double-headed glue discharge needle 305 are arranged in the vertical direction, and the glue discharge port of the single-headed glue discharge needle 306 is located between the two glue discharge ports of the double-headed glue discharge needle 305 in the vertical direction. The double-headed glue discharge needle 305 is used to apply quick-setting glue, and the single-headed glue discharge needle 306 is used to apply adhesive glue. The glue remaining on the two glue discharge needles drips onto the glue receiving tray 7 for easy cleaning.

[0024] During operation, as the lens support 6 rotates, the double-headed glue needle 305 first coats the outer edge of the lens with two circles of quick-setting glue, and then the single-headed glue needle 306 fills the space between the two circles of quick-setting glue. The two layers of quick-setting glue are quickly cured to confine the adhesive in between, thereby preventing dripping during transportation between processes. During installation, when the inner surface of the frame approaches the lens, the adhesive overflows over the quick-setting glue on both sides, thereby completely bonding the lens to the frame. The two circles of quick-setting glue provide overflow space for the adhesive during installation, effectively avoiding the risk of the adhesive overflowing to the lens surface, thereby reducing the production resources consumed in cleaning the overflowed glue.

[0025] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
