Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for optical lens processing, specifically a coating plate suitable for optical lenses. Background Technology
[0002] With the rapid development of science and technology and the continuous improvement of social standards, optical lenses have been widely used in digital cameras, mobile phones, projectors, camcorders and other technical fields. During the production process, optical lenses need to ensure high purity, transparency and uniformity. The coating process is one of the important steps in the subsequent processing. Therefore, a coating plate assembly is needed to support the optical lens. Generally, the coating plate has a series of support holes. Before coating, the lens needs to be installed in these holes. To prevent the lens from falling out, these holes are the same diameter as the lens, so that the lens can be held in the holes.
[0003] A search revealed that patent publication number CN219861552U discloses a coating plate assembly for optical lens coating, comprising a coating plate and an outer jacket plate. The outer periphery of the coating plate is disposed inside the outer jacket plate, and multiple limiting grooves are provided on the outer periphery of the coating plate. Multiple fixing mechanisms are provided in the middle of the coating plate. The fixing mechanism includes a slot, a hidden groove, a spring, and a locking block. The slot is located in the middle of the coating plate, and the hidden groove is located on the outer periphery of the slot. This invention provides a coating plate assembly for optical lens coating. When the lens is placed inside the guide groove, and then the lens is pressed down, the edge of the lens presses against the locking block. After releasing the pressure, the spring holds the locking block in place, thus effectively fixing the lens. When the lens needs to be removed, the coating plate is placed inside the outer jacket plate, and the coating plate is pressed down, causing a top post to extend into the fixing mechanism, thereby pushing the lens upwards and freeing it from the locking block's restriction, allowing for easy removal of the lens. The installation and removal of lenses is very convenient.
[0004] In practical use, the above-mentioned technical solution involves inserting uncoated optical lenses into a fixing mechanism. After the optical lenses are coated, they are ejected from the fixing mechanism using an ejection structure. This coating and removal process easily damages the optical lenses, affecting the yield rate of the finished products. Currently, workers typically use tweezers to remove the coated lenses from the coating plate. However, the optical lenses generally have a gap fit with the holes in the coating plate, making it difficult for workers to remove them in one go with tweezers. The tweezers repeatedly touch the surface of the optical lenses during the gripping process, easily causing scratches and other damage, further affecting the yield rate of the finished products. The efficiency of removing coated optical lenses is also low. Therefore, a coating plate suitable for optical lenses needs to be designed. Utility Model Content
[0005] In view of the defects or shortcomings of coating plates for optical lenses, the purpose of this utility model is to provide a coating plate suitable for optical lenses, which makes it easier for workers to remove the coated optical lenses with tweezers, and avoids the situation where the surface of the optical lenses is scratched due to repeated contact between the tweezers and the optical lens during the process of picking up the optical lenses.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0007] This utility model provides a coating plate suitable for optical lenses, including a housing, with the coating plate mounted on the top of the housing. The surface of the coating plate has an inverted frustum-shaped placement holes and grooves arranged in a ring array, and the grooves are located on one side of the inner wall of the inverted frustum-shaped placement holes. The interior of the housing is provided with a movable plate and a lifting assembly for moving the movable plate in the Y-axis direction. The upper surface of the movable plate is provided with protrusions arranged in a ring array, and the protrusions on the movable plate correspond to the grooves on the coating plate.
[0008] Preferably, the coated plate is fixedly connected to the housing by fastening bolts, and the outer wall of the protrusion and the groove wall are in clearance fit.
[0009] Preferably, the lifting assembly is provided with a second rotating shaft, the bottom end of the second rotating shaft is installed in a bearing seat, and the bearing seat is installed at the center of the bottom end inside the housing. A second bevel gear is provided below the outer wall of the second rotating shaft.
[0010] Preferably, the second bevel gear meshes with the first bevel gear, and the first bevel gear is installed at one end of the first rotating shaft. The other end of the first rotating shaft extends to the outside through the bearing on the outer wall of the connecting block and the bearing on the circumferential outer wall of the housing, and is connected to the rotating adjustment plate.
[0011] Preferably, the outer circumferential wall of the movable plate and the inner circumferential wall of the housing are in clearance fit, a threaded sleeve is provided at the center of the surface of the movable plate, the threaded sleeve is provided on the second rotating shaft, the outer circumferential wall of the second rotating shaft is provided with external thread, and the external thread on the second rotating shaft and the threaded hole on the threaded sleeve are in threaded fit connection.
[0012] Preferably, the bottom of the housing is provided with guide rods arranged in a ring array. The top of the guide rods penetrates through a through hole on the surface of the movable plate. The through holes are arranged in a ring array on the surface of the movable plate, and the outer diameter of the guide rods is equal to the diameter of the through hole.
[0013] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0014] 1. In this utility model, through a series of structural arrangements, during the coating operation of the optical lens, the operator places the optical lens in an inverted frustum-shaped placement hole. When the operator removes the coated optical lens, rotating the adjusting plate on the lifting assembly clockwise or counterclockwise indirectly drives the second rotating shaft to rotate clockwise or counterclockwise. Because the external thread on the second rotating shaft and the threaded hole on the threaded sleeve are connected by a threaded engagement, the clockwise or counterclockwise rotation of the second rotating shaft causes the threaded sleeve to move linearly in the Y-axis direction. This linear movement of the threaded sleeve in the Y-axis direction, in turn, drives the moving plate to move linearly in the Y-axis direction. The linear motion allows the operator to move the protrusion on the moving plate out of the groove on the coating plate. Then, using tweezers, the operator picks up the optical lens from the inverted frustum-shaped placement hole through the groove. This allows the operator to remove the coated optical lens from the inverted frustum-shaped placement hole in a single operation. This device facilitates the removal of coated optical lenses by tweezers, improving the efficiency of lens removal and avoiding scratches caused by repeated contact between the tweezers and the lens surface during handling. This ultimately increases the pass rate of coated optical lenses.
[0015] 2. In this utility model, through a series of coordinated structural arrangements, compared with the operation of removing the coated optical lens in the prior art, this device effectively avoids damage to the coated optical lens and prevents the qualified rate of the coated optical lens from decreasing due to the removal operation. It is highly practical. Attached Figure Description

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0031] like Figure 1-6 As shown, a coating plate suitable for optical lenses includes a housing 100. A coating plate 400 is mounted on the top of the housing 100. The surface of the coating plate 400 has an inverted frustum-shaped placement holes 410 and grooves 420 arranged in a ring array. The grooves 420 are located on one side of the inner wall of the inverted frustum-shaped placement holes 410. The inverted frustum-shaped placement holes 410 are used to place optical lenses of different outer diameters. The interior of the housing 100 is provided with a movable plate 300 and a lifting assembly 200 for moving the movable plate 300 in the Y-axis direction. The upper surface of the movable plate 300 is provided with an annular array of protrusions 310, and the protrusions 310 on the movable plate 300 correspond to the grooves 420 on the coating plate 400.
[0032] The coated plate 400 is fixedly connected to the housing 100 by fastening bolts. The outer wall of the protrusion 310 and the groove wall of the groove 420 are in clearance fit. Because the outer wall of the protrusion 310 and the groove wall of the groove 420 are in clearance fit, it is easy to move the protrusion 310 into the groove 420 or remove the protrusion 310 from the groove 420.
[0033] The lifting assembly 200 is provided with a second rotating shaft 230. The bottom end of the second rotating shaft 230 is installed in the bearing seat 240, and the bearing seat 240 is installed at the center of the bottom end inside the housing 100. A second bevel gear 231 is provided below the outer wall of the second rotating shaft 230.
[0034] The second bevel gear 231 meshes with the first bevel gear 212, and the first bevel gear 212 is installed at one end of the first rotating shaft 210. The other end of the first rotating shaft 210 passes through the bearing on the outer wall of the connecting block 220 and the bearing on the circumferential outer wall of the housing 100, extends to the outside, and is connected to the rotating adjustment plate 211. When the operator rotates the rotating adjustment plate 211 forward or backward, it will drive the first rotating shaft 210 to rotate forward or backward. When the first rotating shaft 210 rotates forward or backward, it will drive the second bevel gear 231 to rotate forward or backward through the first bevel gear 212. When the second bevel gear 231 rotates forward or backward, it will drive the second rotating shaft 230 to rotate forward or backward.
[0035] The outer circumferential wall of the movable plate 300 and the inner circumferential wall of the housing 100 are in clearance fit. A threaded sleeve 320 is provided at the center of the surface of the movable plate 300. The threaded sleeve 320 is provided on the second rotating shaft 230. An external thread is provided on the outer circumferential wall of the second rotating shaft 230. The external thread on the second rotating shaft 230 and the threaded hole on the threaded sleeve 320 are in threaded fit connection.
[0036] Inside the housing 100, at the bottom, there are guide rods 110 arranged in a ring array. The top of the guide rods 110 penetrates through holes on the surface of the movable plate 300. The through holes are arranged in a ring array on the surface of the movable plate 300, and the outer diameter of the guide rods 110 is equal to the diameter of the through holes. Because the outer diameter of the guide rods 110 is equal to the diameter of the through holes, it can limit and guide the movement of the movable plate 300.
[0037] Working principle: During the coating process of optical lenses, the operator places the optical lens in the frustum-shaped placement hole 410. When the operator removes the coated optical lens, rotating the rotary adjustment plate 211 on the lifting assembly 200 clockwise or counterclockwise indirectly drives the second rotating shaft 230 to rotate clockwise or counterclockwise. Because the external thread on the second rotating shaft 230 and the threaded hole on the threaded sleeve 320 are threadedly connected, the clockwise or counterclockwise rotation of the second rotating shaft 230 causes the threaded sleeve 320 to move linearly in the Y-axis direction. The linear movement of the threaded sleeve 320 in the Y-axis direction drives the moving plate 300 to move linearly in the Y-axis direction. After the operator removes the protrusion 310 on the moving plate 300 from the groove 420 on the coating plate 400, the operator uses tweezers to remove the protrusion 410 from the groove 420. The device uses 20 grippers to remove optical lenses from the frustum-shaped placement holes 410 after coating. This allows operators to remove the coated optical lenses from the holes 410 in a single gripping operation. This simplifies the process of removing coated optical lenses using tweezers, improving efficiency and preventing scratches caused by repeated contact between the tweezers and the lens surface. This increases the pass rate of coated optical lenses. Compared to the procedures described in the reference document, this device effectively avoids damage to the coated optical lenses and prevents a decrease in the pass rate due to improper removal.
[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
