Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to an optical lens coating device. Background Technology

[0002] Optical coating refers to the process of depositing one (or more) thin films of metal (or dielectric) onto the surface of an optical lens. The purpose is to reduce or increase light reflection, beam splitting, color separation, filtering, polarization, and other requirements.

[0003] According to a publicized optical lens coating device (publication number: CN219195116U), in the above application, the arc-shaped limiting block can initially limit the optical lens; by opening a conical opening and a flat groove, it is easier to place the arc-shaped surface and the horizontal surface of the optical lens stably; starting the air pump can generate an adsorption force on the optical lens, thereby achieving the purpose of conveniently fixing multiple sets of optical lenses at the same time.

[0004] However, in actual use, when placing optical lenses on the feeding tray, they need to be pressed into the gaps between the arc-shaped positioning blocks one by one, and it must be ensured that each placement opening that is connected to the bottom cavity is covered by the optical lens. Once the placement position of an optical lens is left empty, the positioning effect cannot be achieved, resulting in a limitation on the number of optical lenses during coating processing and reducing the actual use effect of the device. In view of this, we propose an optical lens coating device. Utility Model Content

[0005] The purpose of this invention is to provide an optical lens coating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical lens coating device, comprising a cabinet, a cabinet door hinged to the front of the cabinet, a coating machine installed on the inner top wall of the cabinet, a hollow cylinder rotatably mounted through the inner bottom wall of the cabinet, a feeding tray fixedly mounted on the top of the hollow cylinder, a servo motor fixedly mounted on the inner bottom wall of the cabinet, a driving bevel gear fixedly mounted on the output end of the servo motor, a driven bevel gear fixedly mounted through the outer wall of the hollow cylinder, and a shielding and positioning component provided on the top of the feeding tray;

[0007] The shielding and positioning component includes an air pump, which is fixedly installed on the bottom outer wall of the cabinet. The material feeding tray has a central cavity inside, a through hole on the top inner wall of the material feeding tray, a material feeding groove on the top surface of the material feeding tray, and a movable cavity on the inner wall of the material feeding tray. A slide rod is slidably installed on the inner surface of the movable cavity. A fan-shaped plate is fixedly installed at the end of the slide rod, a spring is fixedly installed on the side wall of the slide rod, and a silicone arc strip is fixedly installed at the other end of the slide rod. An arc-shaped pressure plate is fixedly installed on the upper surface of the silicone arc strip.

[0008] Preferably, the through hole is connected to the central cavity, and the movable cavity is located between the discharge trough and the central cavity, while the through hole is located at the center of the discharge trough.

[0009] Preferably, the number of feeding slots is set to several groups, and the several groups of feeding slots are evenly distributed on the outer surface of the feeding tray, thereby providing sufficient placement space for optical lenses and enabling a large number of optical lenses to be coated at one time.

[0010] Preferably, the diameter of the fan-shaped plate is larger than the inner diameter of the through hole, and the number of the fan-shaped plate, slide bar, spring, silicone arc strip and arc pressure plate is set in three sets. The three sets of fan-shaped plates, slide bars, springs, silicone arc strip and arc pressure plate are arranged in a circumferential array inside the feeding groove, so that the periphery can be squeezed and positioned when the optical lens is placed.

[0011] Preferably, the upper surface of the silicone arc strip near the center of the feeding trough is inclined to facilitate the placement of optical lenses.

[0012] Preferably, the side of the arc-shaped pressure plate is provided with a clamping assembly, the clamping assembly includes a pull rod, the end of the pull rod is hinged to the inner wall of the arc-shaped pressure plate, the other end of the pull rod is hinged to the arc-shaped inner wall of the feeding groove, and the inside of the silicone arc strip is provided with a deformation cavity.

[0013] Preferably, the hinge point between the pull rod and the arc-shaped pressure plate is located on the side of the arc-shaped pressure plate that is biased towards the center of the discharge trough, the cross-section of the deformation cavity is set in the shape of a trapezoidal right trapezoid, and the inclined surface of the deformation cavity is set on the side away from the center of the discharge trough.

[0014] Compared with the prior art, the present invention provides an optical lens coating device, which has the following beneficial effects:

[0015] 1. This optical lens coating device, by setting up a shielding and positioning component, uses the elastic force of springs to completely seal the through holes of the three sets of fan-shaped plates. Therefore, the through holes of the feeding slot at this position remain closed when the optical lens is not pressed in, thus not affecting the positioning effect of the air pump and the central cavity on the optical lenses placed in other feeding slots by negative pressure. This improves the speed of manual feeding of optical lenses and avoids the problem of a single optical lens not being placed properly affecting the placement and positioning of all optical lenses, thereby affecting the coating processing efficiency of the optical lenses.

[0016] 2. This optical lens coating device is equipped with a clamping component. When the silicone arc strip and the arc-shaped pressure plate move towards the center of the feeding groove under the elastic force of the spring and squeeze the optical lens to achieve positioning, the pull rod tightens the bottom of the arc-shaped pressure plate. At this time, the arc-shaped pressure plate tilts downward to press the silicone arc strip, causing the silicone arc strip to press and limit the side of the optical lens, ensuring its positioning stability in the feeding groove, thereby ensuring the stability of the optical lens during the coating process.

[0024] like Figures 1-6As shown, this utility model provides a technical solution: an optical lens coating device, including a cabinet 1, a cabinet door 2 hinged to the front of the cabinet 1, a coating machine 3 installed on the top inner wall of the cabinet 1, a hollow cylinder 4 rotatably installed through the bottom inner wall of the cabinet 1, a feeding tray 5 fixedly installed at the top of the hollow cylinder 4, a servo motor 6 fixedly installed on the bottom inner wall of the cabinet 1, a driving bevel gear 7 fixedly installed at the output end of the servo motor 6, a driven bevel gear 8 fixedly installed through the outer wall of the hollow cylinder 4, and a blocking and positioning component 9 installed on the top of the feeding tray 5. The blocking and positioning component 9 includes an air pump 91, a central cavity 92, a through hole 93, a feeding groove 94, a movable cavity 95, a slide bar 97, a fan-shaped plate 96, a spring 98, a silicone arc strip 99, and an arc-shaped pressure plate 910.

[0025] In one embodiment of this utility model, the air pump 91 is fixedly installed on the bottom outer wall of the cabinet 1. The inside of the feeding tray 5 is provided with a central cavity 92. The top inner wall of the feeding tray 5 is provided with a through hole 93. The top surface of the feeding tray 5 is provided with a feeding groove 94. The inner wall of the feeding tray 5 is provided with a movable cavity 95. The inner surface of the movable cavity 95 is slidably installed with a slide rod 97. The end of the slide rod 97 is fixedly installed with a fan-shaped piece 96. The side wall of the slide rod 97 is fixedly installed with a spring 98. The other end of the slide rod 97 is fixedly installed with a silicone arc strip 99. The upper surface of the silicone arc strip 99 is fixedly installed with an arc-shaped pressure plate 910.

[0026] Furthermore, the feeding tray 5 is cone-shaped, and the coating machine 3 is positioned above the feeding tray 5. After the optical lens is placed on the feeding tray 5, the coating operation can be performed on it. At the same time, the driven bevel gear 8 and the driving bevel gear 7 mesh together to achieve transmission. Thus, during the coating process, the servo motor 6 is started, which, in conjunction with the transmission of the driving bevel gear 7 and the driven bevel gear 8, enables the hollow cylinder 4 to drive the feeding tray 5 to rotate relatively slowly inside the cabinet 1.

[0027] Meanwhile, the output end of the air pump 91 is connected to the internal cavity of the hollow cylinder 4. When the air pump 91 is started, the air in the hollow cylinder 4 and the central cavity 92 is extracted to form a negative pressure state. In addition, the through hole 93 is connected to the central cavity 92, and the movable cavity 95 is located between the feeding groove 94 and the central cavity 92. At the same time, the through hole 93 is set at the center of the feeding groove 94. During the feeding process, the operator places the optical lens in the feeding groove 94, and the back of the optical lens covers the through hole 93. At this time, the air pump 91 is started, and the negative pressure state in the central cavity 92 can adsorb the optical lens through the through hole 93, thereby keeping it in a limited state in the feeding groove 94. At the same time, there are several sets of feeding grooves 94, which are evenly distributed on the outer surface of the feeding tray 5, thereby providing sufficient placement space for the optical lens and allowing a large number of optical lenses to be coated at one time.

[0028] Furthermore, the diameter of the fan-shaped plate 96 is larger than the inner diameter of the through hole 93, and three sets of fan-shaped plates 96, slide bars 97, springs 98, silicone arc strips 99, and arc-shaped pressure plates 910 are arranged in a circumferential array inside the feeding groove 94, thereby enabling the peripheral compression and positioning of the optical lens during placement. Further, the upper surface of the silicone arc strip 99 near the center of the feeding groove 94 is inclined to facilitate the placement of the optical lens. Meanwhile, the spring 98 is positioned away from the slide bar 97... The end is fixedly connected to the inner wall of the movable cavity 95. In the initial state, the spring force of the spring 98 makes the three sets of fan-shaped plates 96 completely close the through hole 93. Therefore, the through hole 93 of the feeding groove 94 at this position remains closed without pressing in the optical lens. Thus, it will not affect the positioning effect of the air pump 91 and the central cavity 92 on the optical lenses placed in other feeding grooves 94 by negative pressure. This improves the speed of manual feeding of optical lenses and avoids the problem of a certain optical lens not being placed properly affecting the placement and positioning of all optical lenses, thereby affecting the coating processing efficiency of the optical lenses.

[0029] Please see Figures 5-6 A pressing assembly 10 is provided on the side of the arc-shaped pressure plate 910. The pressing assembly 10 includes a pull rod 101. The end of the pull rod 101 is hinged to the inner wall of the arc-shaped pressure plate 910, and the other end of the pull rod 101 is hinged to the arc-shaped inner wall of the discharge groove 94. A deformation cavity 102 is opened inside the silicone arc strip 99.

[0030] In this embodiment of the present invention, the hinge point between the pull rod 101 and the arc-shaped pressure plate 910 is located on the side of the arc-shaped pressure plate 910 that is biased toward the center of the feeding groove 94, and the interior of the deformation cavity 102 is filled with inert gas. Specifically, the cross-section of the deformation cavity 102 is set in the shape of a trapezoidal right trapezoid, and the inclined surface of the deformation cavity 102 is set on the side away from the center of the feeding groove 94. When the silicone arc strip 99 and the arc-shaped pressure plate 910 move toward the center of the feeding groove 94 under the elastic force of the spring 98 and squeeze the optical lens to achieve positioning, the pull rod 101 has a tightening effect on the bottom of the arc-shaped pressure plate 910. At this time, the arc-shaped pressure plate 910 tilts downward to press the silicone arc strip 99, causing the silicone arc strip 99 to press and limit the side of the optical lens, ensuring its positioning stability in the feeding groove 94, thereby ensuring the stability of the optical lens during the coating process.

[0031] In this invention, during use, the optical lens is aligned with the center of the feeding slot 94 and pressed in. Through the compression of the optical lens against the silicone arc strip 99, under the elastic force of the spring 98, the slide rod 97 drives the fan-shaped piece 96 and the silicone arc strip 99 to move towards the center of the feeding slot 94, thereby achieving the centered positioning of the optical lens. At the same time, the fan-shaped piece 96 does not completely block the through hole 93. After the optical lens is placed, the air pump 91 is started, and negative pressure is formed inside the feeding tray 5 through the internal cavity of the hollow cylinder 4 and the central cavity 92, thereby achieving the positioning of the optical lens in the feeding slot 94. Then, the cabinet door 2 is closed, the servo motor 6 is started, and with the cooperation of the active bevel gear 7 and the driven bevel gear 8, the hollow cylinder 4 drives the feeding tray 5 to rotate slowly, which, in conjunction with the operation of the coating machine 3, realizes the coating processing of the optical lens.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
