Description

Technical Field

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

[0002] In the field of optical lens manufacturing, grinding is a key process. By grinding the lens blank with grinding equipment, not only can the final size of the lens be precisely controlled, but its surface can also achieve the required optical smoothness to meet the imaging quality requirements. Currently, common grinding equipment is usually equipped with a special loading fixture or jig for positioning and holding lenses during the grinding process. When the operator is performing the processing operation, he or she must first manually place the lens to be processed into the loading structure, and then take it out after the grinding process is completed. However, after grinding is completed, due to the tight fit between the lens and the mounting structure or slight adhesion caused by coolant or debris, operators often cannot safely remove the lens by hand. Therefore, external tools such as suction pens, tweezers, or pry bars must be used to assist in removing the lens. This material handling method has the following main problems: each time material is handled, tools must be found and then a series of steps such as alignment, adsorption or clamping, and removal are performed. This not only extends the operation cycle of a single product and reduces the overall production efficiency, making it difficult to adapt to the needs of automation or mass production, but also makes it very easy for manual material handling to scratch or collide with the polished precision optical surface. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an optical lens grinding device that solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An optical lens grinding device includes: a processing tank, a protective cover movably mounted on the top of the processing tank, a rubber isolation curtain fixedly mounted on the bottom of the protective cover, a grinding unit assembled inside the protective cover, five sets of sliding components arrayed at the bottom of the processing tank, a loading cylinder fixedly mounted on the sliding end of the sliding components, a material ejector assembly assembled inside the loading cylinder, and five sets of ejection trigger rods arrayed on the inner wall of the processing tank, the ejection trigger rods engaging with the loading cylinder; the grinding unit includes a main propulsion cylinder, a cylinder mounting plate, and a telescopic rod; the cylinder mounting plate is fixedly mounted on the inner wall of the protective cover, an extended telescopic rod is connected to the inside of the cylinder mounting plate, the main propulsion cylinder is fixedly mounted on the protective cover above the cylinder mounting plate, a fixing block is connected to the output end of the main propulsion cylinder, the bottom of the fixing block is connected to the telescopic rod, an angle adjustment cylinder is fixedly mounted on the front of the fixing block, a mounting frame is fixedly mounted together with the front end of the angle adjustment cylinder and the telescopic rod, and an electric grinding head is fixedly mounted inside the mounting frame. This invention provides an optical lens grinding device. Compared with the prior art, it has the following advantages: 1. Five sets of independent sliding parts and loading cylinders enable multi-station parallel operation. While the equipment is processing one station, the operator can load and unload materials at other stations, overlapping auxiliary time with processing time, which greatly improves equipment utilization and overall production efficiency. The push handle and guide rail enable quick, easy, and accurate switching between workstations, reducing the labor intensity of operators. The mechanical linkage between the ejector assembly and the ejection trigger rod eliminates the need for manual lens removal, avoiding contact contamination and potential scratches on the surface of the precision lens. The ejection is triggered by the kinetic energy of the sliding mechanism, resulting in a simple structure and low failure rate.

[0005] 2. A dynamically sealed protective space is formed by the protective cover and the rubber isolation curtain; Effective sealing: During machining, it can completely block the splashing of cutting fluid and grinding debris, keep the working environment clean, and prevent coolant atomization and leakage; Unobstructed access: The flexibility of the rubber isolation curtain allows the loading cylinder to be pushed in and pulled out without obstruction, achieving a perfect balance between protection and ease of operation.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0010] To address the technical problems in the background section, the following optical lens grinding equipment is provided: Combination Figures 1-5As shown, the optical lens grinding equipment provided by this utility model includes: a processing tank 100, a protective cover 200 movably installed on the top of the processing tank 100, a rubber isolation curtain 201 fixedly installed on the bottom of the protective cover 200, a grinding unit 300 assembled inside the protective cover 200, five sets of sliding parts 600 arrayed at the bottom of the processing tank 100, a loading cylinder 500 fixedly installed at the sliding end of the sliding parts 600, a material ejection assembly 700 assembled inside the loading cylinder 500, and five sets of ejection trigger rods 400 arrayed on the inner wall of the processing tank 100, with the ejection trigger rods 400 and the loading cylinder 500 engaging with each other; the grinding unit 300 includes a main propulsion cylinder 301, a cylinder mounting plate 302, and a telescopic rod 303, the cylinder mounting plate 302 fixedly installed on the inner wall of the protective cover 200, and an extended telescopic rod 303 engaging inside the cylinder mounting plate 302. A main propulsion cylinder 301 is fixedly installed on the protective cover 200 above the cylinder mounting plate 302. A fixing block 310 is connected to the output end of the main propulsion cylinder 301, and the bottom of the fixing block 310 is connected to the telescopic rod 303. An angle adjustment cylinder 309 is fixedly installed on the front of the fixing block 310. An installation frame 307 is fixedly installed together with the front end of the angle adjustment cylinder 309 and the telescopic rod 303. An electric grinding head 305 is fixedly installed inside the installation frame 307. The top material assembly 700 includes a lower top cap 701, a spring 702, a top rod 703, and a fixing plate 704. The fixing plate 704 is fixedly installed inside the loading cylinder 500. A spring 702 is fixedly installed at the bottom of the fixing plate 704. A lower top cap 701 is fixedly installed at the bottom of the spring 702. A top rod 703 that penetrates the fixing plate 704 is fixedly connected to the middle of the top surface of the lower top cap 701. An upper top cap 705 is fixedly installed at the top of the top rod 703.

[0011] In the above scheme: Equipment basic structure: The processing tank 100 serves as the basic platform, and a protective cover 200 is installed on its top via a hinge; the rubber isolation curtain 201 at the bottom of the protective cover 200 can effectively block the splashing of cutting fluid during grinding; Grinding unit 300: This unit is the core actuator of the equipment. The main propulsion cylinder 301 serves as the main drive, which can push the entire grinding mechanism to move back and forth. The angle adjustment cylinder 309 drives the mounting frame 307 and the electric grinding head 305 to adjust the pitch angle through a unique linkage mechanism composed of sliding block 311 and hinge seat 304, so as to adapt to the lens grinding requirements of different angles. The vertical feed cylinder 308 is responsible for driving the electric grinding head 305 to perform vertical feed motion. Five loading cylinders 500 are installed in the machining tank via a sliding component 600 at the bottom and can slide independently to the grinding station. Each loading cylinder 500 contains an ejector assembly 700. Under the action of the spring 702, the upper cap 705 at the top of the ejector rod 703 is usually in a low position. When it is necessary to eject the lens, the external ejection trigger rod 400 will press against the lower cap 701, compress the spring 702 and raise the ejector rod 703 to eject the lens.

[0012] In this embodiment, a cover handle 202 is fixedly installed on the front side of the protective cover 200, and a hinge mounting base 101 is fixedly installed on the back side of the processing groove 100. A hinge connector 102 is movably installed in the hinge mounting base 101 through a pin, and the hinge connector 102 is fixedly connected to the back side of the protective cover 200.

[0013] When the equipment needs maintenance, replacement of the grinding head, or cleaning of the interior, the operator can hold the cover handle 202 on the front side of the protective cover 200 and flip the protective cover upwards. The hinge connector 102 on the back is connected to the hinge mounting base 101 by a pin, ensuring smooth and stable opening and closing action. This design greatly facilitates the daily maintenance and upkeep of the equipment.

[0014] In this embodiment, the grinding unit 300 further includes a hinge seat 304, a carrier plate 306, a vertical feed cylinder 308, and a sliding block 311. The end of the telescopic rod 303 is fixedly connected to the hinge seat 304. A hinge block 313 connected to the mounting frame 307 is hingedly installed inside the hinge seat 304. The output end of the angle adjustment cylinder 309 is hingedly installed with the sliding block 311. A slide rail 312 connected to the mounting frame 307 is slidably connected on the sliding block 311. The vertical feed cylinder 308 is fixedly installed on the top of the mounting frame 307, and the output end of the vertical feed cylinder 308 passes through the mounting frame 307 and is connected to the carrier plate 306. The electric grinding head 305 is installed on the top of the carrier plate 306.

[0015] The piston rod of the angle adjustment cylinder 309 extends and retracts, pushing the sliding block 311 connected thereto. Since the mounting bracket 307 is simultaneously in sliding contact with the hinge seat 304 and the sliding block 311, this movement will be converted into the precise pitch rotation of the mounting bracket 307 around the hinge seat 304, which allows the electric grinding head 305 to be precisely adjusted to the preset grinding angle. The electric grinding head 305 is mounted on the carrier plate 306 and is driven by the vertical feed cylinder 308 to achieve vertical feed. The carrier plate 306 integrates a liquid nozzle, which can be connected to an external cutting fluid pipeline to precisely cool and flush the grinding point during grinding, thereby improving grinding quality and tool life.

[0016] In this embodiment, the sliding component 600 includes a guide rail 601 and a guide block 602. The bottom array of the processing groove 100 is equipped with the guide rail 601, and the guide block 602 is slidably connected on the guide rail 601. The bottom of the loading cylinder 500 is installed on the top of the guide block 602.

[0017] At the bottom of the processing tank 100, five sets of parallel guide rails 601 are precisely installed. The bottom of each loading cylinder 500 is slidably engaged with the guide rail 601 through the guide block 602. This structure ensures that the loading cylinder 500 can smoothly and linearly enter and exit the grinding station when manually pushed, thus guaranteeing the alignment accuracy between the lens and the grinding head.

[0018] In this embodiment, a loading head 501 is fixedly installed on the top of the loading cylinder 500, and a top outlet 502 communicating with the loading cylinder 500 is provided at the bottom of the loading head 501. The top outlet 502 corresponds to the upper cap 705, and a pusher 504 is fixedly installed on one side of the loading cylinder 500.

[0019] Workpiece clamping: The operator places the lens to be ground in the positioning surface of the loading head 501. The design of the loading head 501 ensures that the initial position of the lens is accurate. Unloading: After processing, the top cap 705 on the top of the push rod 703 rises from the top outlet 502, smoothly lifting the lens that has been ground, so that it is removed from the positioning surface of the loading head 501, making it easy for personnel to pick up. Easy to operate: The push handle 504 provides the operator with a clear point of force application, making it easy to push and pull the loading cylinder.

[0020] In this embodiment, the loading cylinder 500 is provided with through interfaces 503 on both the front and rear sides, and the interfaces 503 correspond to the ejection trigger rod 400.

[0021] When the loading cylinder 500 is pulled back to the loading and unloading position, the interface 503 on its side wall will be aligned with the ejection trigger rod 400 fixed to the inner wall of the processing tank. As the loading cylinder continues to move, the ejection trigger rod 400 will pass through the interface 503 and press precisely against the lower cap 701 of the ejection assembly 700, thereby triggering the ejection action. This design does not require an additional power source and can achieve automated unloading with only simple mechanical linkage. The structure is ingenious and reliable.

[0022] Working principle and usage process of this utility model: When in use, the electrical components on the equipment are matched and connected with the external control system, which can be integrated and controlled by a PLC; During processing, the external cutting fluid line is connected to the fluid nozzle on the carrier plate 306 to ensure that the fluid nozzle can supply fluid to the grinding position on its respective during grinding. The operator places the lens in the loading head 501 for positioning, and then pushes the loading cylinder 500 with the pusher 504 to make it reach the processing point of the grinding unit 300, ensuring that the lens in the loading head 501 corresponds to the electric grinding head 305. The operator first starts the angle adjustment cylinder 309 to drive the mounting frame 307 through the front sliding block 311. The mounting frame 307 uses the sliding block 311 to create a sliding hinge with the angle adjustment cylinder 309, and uses the hinge seat 304 to move and hinge with the telescopic rod 303, so that the mounting frame 307 itself and its internal structure tilt synchronously to adapt to the grinding requirements of the lens. During grinding, the vertical feed cylinder 308 is activated to push the carrier plate 306, which causes the carrier plate 306 to drive the electric grinding head 305 at the bottom to descend. The electric grinding head 305 rotates electrically to achieve the grinding operation of the lens. The electric grinding head 305 is composed of a motor and a grinding head. During this period, the main propulsion cylinder 301 can be started simultaneously. The output end of the main propulsion cylinder 301 drives the telescopic rod 303 and the angle adjustment cylinder 309 simultaneously through the fixed block 310, thereby realizing the synchronous push of the mounting bracket 307. At that time, the electric grinding head 305 completes the grinding operation of the lens under reciprocating motion. The splashing liquid generated during grinding will be blocked by the protective cover 200 and the rubber isolation curtain 201. During material loading and unloading, the rubber isolation curtain 201 will not obstruct the loading cylinder 500, ensuring that it can enter and exit stably. During cleaning and maintenance, personnel can simply flip up and open the protective cover 200 using the cover handle 202. After polishing, personnel can pull the loading cylinder 500 outward using the pusher 504. With continuous pulling, the interface 503 on the loading cylinder 500 connects with the ejector trigger rod 400, causing the ejector trigger rod 400 to insert into the loading cylinder 500. At this time, the ejector trigger rod 400 can abut against the lower cap 701, causing the lower cap 701 to drive the top rod 703 to rise. When rising, the spring 702 enters a compressed state, and the upper cap 705 at the top of the rod 703 can penetrate the outlet 502, thus ejecting the lens from the loading head 501. Personnel can then quickly remove the lens.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
