Description

Technical Field

[0001] This utility model relates to the field of optical lens manufacturing technology, and in particular to an optical lens core extraction device. Background Technology

[0002] Optical lenses are transparent materials, usually made of glass or plastic, used to control and regulate the propagation of light. They play a key role in a variety of optical devices and instruments. The optical lens core-taking device is used to polish the edges of optical lenses to improve their resistance to cracking and appearance quality. Through the core-taking operation, it is ensured that the optical axis of the lens coincides with the outer diameter center axis, thereby improving the coaxiality of the lens system. This is an important process to ensure optical performance.

[0003] During the core-taking process of optical lenses, the grinding wheel needs to grind the lens edge under the lubrication and cooling effect of coolant or water flow. For example, the prior art, Chinese Patent Publication No. "CN216399077U", describes an optical lens core-taking device, which includes a housing. A diamond grinding wheel driven by a motor is installed inside the housing. A fixed plate is provided at the front end of the diamond grinding wheel. A first movable plate is slidably connected in a first groove. Two sliding rails that move back and forth are provided on the first movable plate. A second movable plate is provided on the sliding rails. A clamping device is provided at the front left side of the second movable plate, and a water tank support column is provided at the rear end. A water outlet plate is slidably connected to the lower end of the water outlet groove. A stop plate is provided on the fixed plate, and the stop plate contacts the baffle. This invention, through the setting of a foldable water outlet plate, allows water flow and the processing surface to operate simultaneously during optical lens core taking, avoiding water waste and preventing damage to the diamond grinding wheel. The clamping device ensures that processing is safe and that the lens is not damaged during grinding.

[0004] In actual operation, considering that the water is poured directly onto the grinding wheel, and the water is prone to splashing when the grinding wheel rotates rapidly, there is no protective structure to stop the splashing water, which can easily pollute the processing environment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that lack protective structures to stop splashing water, and to propose an optical lens core extraction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an optical lens core extraction device, including a base, a box fixedly connected to the top of the base, a clamping mechanism and a grinding mechanism are arranged inside the box, the grinding mechanism includes a grinding wheel and a coolant nozzle placed between the lens and the grinding wheel;

[0008] The container is equipped with a protective cover at the inlet to prevent coolant from splashing out. A cleaning component is provided between the protective cover and the container to scrape off and clean the coolant adhering to the inside of the protective cover.

[0009] Furthermore, the cleaning component includes a connecting rod, which is rotatably connected to the inner top of the housing on the opening side via a torsion spring. A protrusion is slidably connected to the end of the connecting rod via a limiting part, and a scraper is fixedly connected to the periphery of the end of the connecting rod.

[0010] Furthermore, a compression spring is also sleeved at the end of the connecting rod, with the two ends of the compression spring abutting against the scraper and the protrusion respectively, wherein the top of the scraper abuts against the protective cover.

[0011] Furthermore, the protective cover has an arc-shaped structure that matches the opening of the box. The side of the protective cover extends towards the axis to form an extension. The extension is provided with a guide slope on the outer side, and the slope of the guide slope gradually increases on the side facing the protrusion.

[0012] The top protrusion of the protrusion abuts against the extension, and the protrusion also abuts against and slides against the guide slope.

[0013] Furthermore, guide posts are fixedly connected to both sides of the tail end of the protective cover, and a positioning glass bead is also embedded on one side. The protective cover is slidably connected to the arc-shaped guide groove on the inner wall of the box through the guide posts and the telescopic column ends of the positioning glass bead.

[0014] Furthermore, the housing has a through hole at one end of the arc-shaped guide groove, and the telescopic end of the positioning glass bead engages in the through hole.

[0015] The optical lens core-taking device proposed in this utility model has the following advantages: The device features a protective cover on the opening side of the housing. This cover serves two purposes: firstly, it shields the lens from splashing coolant, preventing contamination of the processing environment; secondly, it stops the lens from becoming loose, improving operational safety; and thirdly, the positioning beads prevent accidental opening or closing of the protective cover. Furthermore, the opening and closing of the protective cover allows for the cleaning of coolant adhering to its surface using a scraper, preventing coolant buildup that could obstruct the operator's monitoring of lens processing and any lens misalignment.

[0022] 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.

[0023] Reference Figure 1-5 An optical lens core extraction device includes a base 1, a housing 2 fixedly connected to the top of the base 1, a clamping mechanism 3 and a polishing mechanism 4 are provided inside the housing 2, and the polishing mechanism 4 includes a polishing wheel 41 and a coolant nozzle 42 placed between the lens and the polishing wheel 41.

[0024] A protective cover 5 is provided at the feed inlet of the housing 2 to prevent coolant from splashing out. A cleaning component 6 is provided between the protective cover 5 and the housing 2 to scrape off and clean the coolant adhering to the inside of the protective cover 5.

[0025] In some embodiments, the clamping mechanism 3 includes a pair of clamping rods, which are arranged opposite to each other and are driven to move relative to each other by a cylinder or an electric push rod to clamp the lens.

[0026] The polishing mechanism 4 also includes a drive component connected to the polishing wheel 41, which drives the polishing wheel 41 to rotate. It also drives the drive component and the polishing wheel 41 to move laterally via a ball screw assembly, so that the polishing wheel 41 can better fit the outer wall of the lens for polishing. Furthermore, the coolant nozzle 42 is mounted on the universal joint rod and is connected to the universal joint rod and the liquid supply device to provide coolant for lubricating and cooling the lens.

[0027] Furthermore, to facilitate the collection of lubricating oil, a collection trough can be installed below the grinding mechanism 4 inside the housing 2. The collection trough is connected to the drain pipe for collecting and discharging excess lubricating oil.

[0028] Furthermore, the cleaning component 6 includes a connecting rod 61, which is rotatably connected to the inner top of the housing 2 on the opening side via a torsion spring 62. The end of the connecting rod 61 is slidably connected to a protrusion 64 via a limiting part 63, and a scraper 65 is fixedly connected to the periphery of the end of the connecting rod 61.

[0029] It should be added that, such as Figure 5 As shown, the limiting part 63 includes a limiting groove and a limiting block. The end of the connecting rod 61 is provided with the limiting groove, and the protrusion 64 is provided with the limiting block at the central through hole. The limiting groove and the limiting block are slidably connected. The limiting part 63 enables the connecting rod 61 to circumferentially lock the protrusion 64, that is, the connecting rod 61 can drive the protrusion 64 to rotate synchronously.

[0030] Furthermore, the two ends of the torsion spring 62 are fixedly connected to the inner wall of the housing 2 and the protrusion 64, respectively. The torsion spring 62 is used to reset the connecting rod 61 and the protrusion 64.

[0031] Furthermore, a compression spring 66 is also sleeved at the end of the connecting rod 61. The two ends of the compression spring 66 abut against the scraper 65 and the protrusion 64, respectively. The top of the scraper 65 abuts against the protective cover 5.

[0032] More specifically, the protective cover 5 has an arc-shaped structure that matches the opening of the box 2. The side of the protective cover 5 extends towards the axis to form an extension 51. The extension 51 is provided with a guide slope 52 on the outer side. The guide slope 52 gradually increases in size towards the protrusion 64.

[0033] The top protrusion of the protrusion 64 abuts against the extension 51, and the protrusion 64 also abuts against and slides against the guide slope 52.

[0034] It is worth mentioning that the scraper 65 is preferably made of materials such as rubber and silicone, and the height of the scraper 65 is higher than that of the protrusion 64 to prevent the protrusion 64 from contacting the protective cover 5;

[0035] In specific operation, when the protective cover 5 is opened, the extension 51 abuts against the protrusion 64. The protrusion 64 is abutted, causing the connecting rod 61 and the scraper 65 to flip. The scraper 65 avoids the protective cover 5. Furthermore, after the protective cover 5 is opened, the protrusion 64 disengages from the extension 51, and the connecting rod 61 is reset under the action of the torsion spring 62. The advantage is that it prevents the scraped coolant from dripping down the front end of the protective cover 5. Due to the loading and unloading of the lens, the coolant should be cleaned along the rear end of the protective cover 5.

[0036] Conversely, when the protective cover 5 is closed, the protrusion 64 slides towards the connecting rod 61 under the guidance of the guide slope 52. Therefore, the connecting rod 61 drives the scraper 65 to reset. The end of the scraper 65 abuts against the inner surface of the protective cover 5, so that the scraper 65 cleans the lubricant adhering to the inner surface when the protective cover 5 is closed. In addition, after the protrusion 64 is separated from the extension 51, it resets under the action of the compression spring 66, waiting for the next contact with the extension 51.

[0037] In general, guide posts 53 are fixedly connected to both sides of the tail end of the protective cover 5, and a positioning glass bead 54 is also embedded on one side. The protective cover 5 is slidably connected to the arc-shaped guide groove 21 on the inner wall of the box 2 through the guide posts 53 and the telescopic column ends of the positioning glass bead 54.

[0038] Finally, the housing 2 has a through hole 22 at one end of the arc-shaped guide groove 21, and the telescopic column end of the positioning glass bead 54 is engaged in the through hole 22.

[0039] In this embodiment, a drive rod is fixedly connected to the front end of the protective cover 5. The telescopic end of the positioning glass bead 54 is engaged in the through hole 22, which can prevent the protective cover 5 from opening or closing in case of accidental contact with the drive rod or accidental operation.

[0040] Working method: During operation, the lens is clamped by the clamping mechanism 3, and the grinding wheel 41, under the action of the driving component, works with the coolant sprayed from the coolant nozzle 42 to grind the edge of the lens. Before grinding, the protective cover 5 needs to be closed to prevent coolant from splashing.

[0041] After polishing, press the telescopic column end of the positioning glass bead 54 to make it retract and disengage from the through hole 22. Then, the protective cover 5 can be flipped open by the drive rod. When the protective cover 5 is opened, the extension part 51 abuts against the protrusion part 64. The protrusion part 64 is abutted and drives the connecting rod 61 and the scraper 65 to flip. The scraper 65 avoids the protective cover 5. After the protective cover 5 is opened, the protrusion part 64 disengages from the extension part 51, and the connecting rod 61 is reset under the action of the torsion spring 62.

[0042] When the protective cover 5 is closed, the protrusion 64 slides toward the connecting rod 61 under the guidance of the guide slope 52. Therefore, the connecting rod 61 drives the scraper 65 to reset and, together with the scraper 65, scrapes off the coolant on the inner surface of the protective cover 5. After the protrusion 64 is separated from the extension 51, it resets under the action of the compression spring 66.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
