Description
Technical Field
[0001] This utility model relates to the field of optical lens coating, specifically to a lens anti-displacement loading fixture for optical lens coating. Background Technology
[0002] Optical lens coating refers to the deposition of one or more thin films of specific materials on the surface of optical lenses using physical or chemical methods to improve their optical performance, mechanical properties, or environmental adaptability. Its core principle is to achieve precise control over properties such as reflection, transmission, and absorption through the interaction between the thin film and light. During the coating process, a fixture is needed to support the optical lens. This optical lens coating fixture is a specialized tool used to fix the optical lens, ensuring its stable position during the coating process and assisting in the control of specific coating areas.
[0003] In the utility model patent application CN214218849U, published on September 17, 2021, entitled "An Optical Lens Coating Fixture," this utility model discloses an optical lens coating fixture applicable to the field of lens coating technology. It includes a substrate with mounting holes. The substrate has a plurality of clamping arms along the periphery of the mounting holes for holding lenses. The clamping arms are rotatably connected to the substrate via rotating shafts. Positioning elements for fixing the clamping arms are provided within the mounting holes. This application uses positioning elements to press the clamping arms against the sidewall of the lens, achieving the effect of clamping the lens. This allows the operator to quickly and conveniently fix the lens, improving the ease of lens fixation and the coating efficiency.
[0004] In the aforementioned patents or prior art, optical lenses not only need to be fixed in position during the coating process, but also need to be positioned accurately. However, the existing fixture fixing methods are prone to causing the lens to shift in position during processing and handling, thus affecting the quality of subsequent coating processing. At the same time, the existing fixture fixing methods are not convenient for picking up and putting down optical lenses before and after processing, thus affecting the overall efficiency.
[0005] Therefore, it is necessary to invent a lens anti-displacement loading fixture for optical lens coating to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a lens anti-displacement loading fixture for optical lens coating. The upward and downward movement of the conical block drives the optical glass above the support platform to move up and down, thereby facilitating its removal and placement. When the conical block moves downward, it can simultaneously squeeze multiple sets of push rods, causing the push rods to drive the rocker arm to simultaneously adhere to the side of the optical glass from various directions, achieving the effect of fixing and correcting the position of the optical glass. This solves the problem in the prior art that the optical glass is prone to positional displacement inside the fixture, affecting the coating effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a lens anti-displacement loading fixture for optical lens coating, comprising a fixture base, a control panel installed on one side of the fixture base, a loading box installed above the fixture base, and multiple loading cavities arranged in an array inside the loading box, each loading cavity being provided with a support platform.
[0008] The correction and anti-deviation assembly installed in the loading cavity includes a fixed cylinder. The fixed cylinder is installed below the inner wall of each group of loading cavities. Each group of fixed cylinders is provided with a conical block, and the upper part of each group of conical blocks is fixedly connected to the corresponding support platform. Each group of conical blocks is symmetrically installed with limit blocks. Each group of fixed cylinders has symmetrical limit grooves on its inner wall, and the limit grooves are slidably connected to the corresponding limit blocks.
[0009] The power assembly installed in the fixture base includes a synchronization plate, guide blocks are symmetrically installed on the side of the synchronization plate, guide grooves are opened on the inner wall of the fixture base, and the guide grooves are slidably connected to the corresponding guide blocks. A connecting rod is installed between the synchronization plate and the bottom of each set of conical blocks.
[0010] Preferably, the correction and anti-deviation component further includes through holes, which are formed on the inner wall of each group of fixed cylinders, and four groups of through holes are formed in a ring on the inner wall of each group of fixed cylinders.
[0011] Preferably, each of the through holes is connected to a push rod, one end of which is in contact with the inclined surface of the conical block. Each of the push rods is fitted with a limit ring, and each of the push rods is fitted with a spring, with the two sides of the spring in contact with the limit ring and the inner wall of the through hole, respectively.
[0012] Preferably, each loading cavity has a rocker arm rotatably connected to its inner wall, and the rocker arms are arranged in a ring with four sets in each loading cavity. Each rocker arm has a rubber pad installed on the side near the support platform above it.
[0013] Preferably, each rocker arm has a groove below it, and the inside of the groove is slidably connected to the end of the push rod away from the conical block.
[0014] Preferably, the power assembly further includes a servo motor, which is installed below the inner wall of the fixture base and electrically connected to the control panel. A screw is rotatably connected above the inner wall of the fixture base, and the screw is threaded through and screwed to the synchronization plate. The output end of the servo motor is connected to the screw shaft.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. By moving the conical block up and down, the inclined surface of the conical block can squeeze one end of the push rod, allowing the push rod to move along the inside of the through hole. The movement of the push rod causes the other end to push the rocker arm to rotate, causing the upper part of the rocker arm to move closer to the support platform. This allows each set of rocker arms to simultaneously adhere to the side of the optical glass, thus fixing the optical glass. At the same time, because each set of rocker arms adheres to the side, the overall position of the optical glass is centered on the support platform, ensuring its positional accuracy.
[0017] 2. The up-and-down movement of the conical block can move the support platform, allowing it to move closer to or further away from the opening of the loading cavity. This makes it convenient for workers to put or take the optical glass into or out of the loading cavity before and after processing. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The above describes a lens anti-displacement loading fixture for optical lens coating, including a fixture base 001, a control panel 101 installed on one side of the fixture base 001, a loading box 102 installed above the fixture base 001, and multiple loading cavities 103 arranged in an array inside the loading box 102, each loading cavity 103 being provided with a support platform 104.
[0028] The support stage 104 can support symmetrical optical lenses, so that the optical lenses can be effectively placed inside the loading cavity 103.
[0029] The correction and anti-deviation assembly 002 installed in the loading cavity 103 includes a fixed cylinder 201. The fixed cylinder 201 is installed below the inner wall of each loading cavity 103. Each fixed cylinder 201 is provided with a conical block 202. The upper part of each conical block 202 is fixedly connected to the corresponding support platform 104. Limiting blocks 203 are symmetrically installed on each conical block 202. Limiting grooves 204 are symmetrically opened on the inner wall of each fixed cylinder 201. The limiting grooves 204 are slidably connected to the corresponding limiting blocks 203.
[0030] With the cooperation of the limiting block 203 and the limiting groove 204, the conical block 202 can move up and down in the fixed cylinder 201, while its movement position is restricted to a certain extent, so that the bearing platform 104 can move up and down, thereby facilitating the placement and removal of optical lenses from the loading cavity 103.
[0031] The power assembly 003 located in the fixture base 001 includes a synchronization plate 303. Guide blocks 304 are symmetrically installed on the side of the synchronization plate 303. A guide groove 305 is provided on the inner wall of the fixture base 001, and the guide groove 305 is slidably connected to the corresponding guide block 304. A connecting rod 306 is installed between the synchronization plate 303 and the bottom of each set of conical blocks 202.
[0032] With the cooperation of guide block 304 and guide groove 305, the synchronous plate 303 can move up and down on the fixture base 001, and the movement of synchronous plate 303 can simultaneously drive each set of conical blocks 202 to move up and down synchronously through connecting rod 306.
[0033] Furthermore, in the above structure, the correction and anti-deviation component 002 also includes through holes 205, which are opened on the inner wall of each group of fixed cylinders 201, and four groups of through holes 205 are opened in a ring on the inner wall of each group of fixed cylinders 201.
[0034] Furthermore, in the above structure, each set of through holes 205 is connected to a push rod 206, and one end of the push rod 206 is in contact with the inclined surface of the conical block 202. Each set of push rods 206 is fitted with a limit ring 207, and each set of push rods 206 is fitted with a spring 208, and the two sides of the spring 208 are in contact with the limit ring 207 and the inner wall of the through hole 205, respectively.
[0035] The spring 208 and the limiting ring 207 work together to keep the push rod 206 in the position of the through hole 205, and the cone block 202 moves downward, which allows its inclined surface to push the push rod 206 to move, thereby compressing the spring 208.
[0036] Furthermore, in the above structure, rocker arms 209 are rotatably connected to the inner wall of each loading cavity 103, and four sets of rocker arms 209 are arranged in a ring in each loading cavity 103. A rubber pad 210 is installed on the side of each rocker arm 209 near the support platform 104.
[0037] Furthermore, in the above structure, each set of rocker arms 209 has a sliding groove 211 below it, and the inside of the sliding groove 211 is slidably connected to the end of the push rod 206 away from the conical block 202.
[0038] One end of the push rod 206 is pressed by the conical block 202, causing the other end of the push rod 206 to slide in the groove 211. This causes the push rod 206 to drive the rocker arm 209 to rotate, so that the rubber pad 210 is attached to the side of the optical lens. Since the four rocker arms 209 are attached and pushed at the same time, the optical lens can be positioned at the center of the support platform 104. The rocker arms 209 can fix the position of the optical lens to prevent the position from shifting during subsequent handling, and also facilitate subsequent coating processing.
[0039] Furthermore, in the above structure, the power assembly 003 also includes a servo motor 301. The servo motor 301 is installed below the inner wall of the fixture base 001 and is electrically connected to the control panel 101. A screw 302 is rotatably connected above the inner wall of the fixture base 001 and is threaded through to the synchronization plate 303. The output end of the servo motor 301 is axially connected to the screw 302.
[0040] The servo motor 301 can drive the screw 302 to rotate, thereby causing the screw 302 to drive the synchronous plate 303 to move up and down.
[0041] The working principle of this practical application is as follows:
[0042] Refer to the instruction manual appendix Figure 1-5 When optical lenses need to be coated, the servo motor 301 is controlled to rotate via the control panel 101, which drives the synchronous plate 303 to move upward. At this time, the rocker arm 209 moves away from the support platform 104, and the support platform 104 moves upward, thus approaching the opening of the loading cavity 103, making it easier for the operator to place the optical lens on it. When the optical lens is placed into each loading cavity 103 in sequence, the servo motor 301 is controlled to rotate via the control panel 101 again, causing the synchronous plate 303 to move downward. This causes the conical block 202 to press the push rod 206, which moves along the through hole 205. At the same time, the push rod 206 pushes the rocker arm 209 downward, causing the rubber pad 210 above the rocker arm 209 to move towards the support platform 104. The optical lenses are brought together sideways. As each set of rocker arms 209 moves together simultaneously, the optical lenses can be corrected in position, thus placing them at the center of the support platform 104. At this point, the entire fixture is placed into the coating equipment for coating processing. After processing, the upward movement of the synchronous plate 303 releases the rocker arms 209 and also moves the support platform 104 upward, thus sending the optical glass to the opening of the loading cavity 103 for easy removal by the operator. This structure effectively corrects and fixes the position of the optical glass before processing, thus preventing the optical glass from shifting and ensuring the quality of the coating process. At the same time, the lifting and lowering of the support platform 104 also facilitates the placement and removal of the optical glass before and after processing.
[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
