Description

Technical Field

[0001] This invention relates to the field of lens processing equipment technology, specifically to an integrated multi-station grinding and polishing equipment for optical lenses and its polishing process. Background Technology

[0002] The multi-station integrated grinding and polishing equipment for optical lenses is designed specifically for grinding or polishing optical surfaces on lenses and other workpieces with similar shapes. It integrates a multi-station collaborative operation structure, which can sequentially complete the rough grinding, fine grinding and polishing processes of optical lenses on the same machine. The machine tool device used for grinding or polishing can realize online repair or adjustment of the worn surface of the grinding wheel through modular station layout. At the same time, it optimizes the feeding method of grinding, polishing or abrasive to improve the processing accuracy and consistency of optical surfaces.

[0003] However, in the grinding process of optical lenses, the industry standard practice is to directly drive the coolant circulation with a water pump for cooling and lubrication. But in actual working conditions, a large amount of glass dust, abrasive particles, and other debris generated during lens grinding will directly mix into the coolant and continuously participate in the processing. This not only significantly reduces the lubrication and cooling performance of the coolant but also accelerates mold wear and may even scratch the surface of the optical lens, directly affecting processing accuracy and product yield. Therefore, we propose a multi-station integrated grinding and polishing equipment for optical lenses and its polishing process. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated multi-station grinding and polishing equipment for optical lenses and its polishing process, so as to solve the problems mentioned in the background art.

The cleaning and filtering structure is used for a series of conveying and filtering operations on the grinding debris generated during the polishing process of optical lenses. The cleaning and filtering structure includes a drive shaft and a driven shaft rotatably connected to the bottom of the water tank. A conveyor belt is driven to the outer side of the drive shaft and the driven shaft. A drain hole is opened on the side wall of the water tank. A brush rod is rotatably connected to the inner side of the water tank near the drain hole. Several bristles are fixedly connected to the side wall of the brush rod. The brush rod is located diagonally below the end of the conveyor belt. A combing and collecting structure is set on the side wall of the water tank. The combing and collecting structure is used for the centralized collection and processing of grinding debris from optical lenses.

[0006] The effect achieved by the above components is as follows: by setting up a cleaning and filtering structure, during the process of transporting and centrally processing impurities after the optical lens is polished, the impurities can be filtered by the brush bristles, and the impurities adhering to the surface of the conveyor belt can be cleaned by the brush bristles, thereby effectively avoiding the accumulation of polishing residue and dirt on the bottom wall of the water tank.

[0007] Preferably, a water tank is fixedly connected to the lower side of the water tank, the water tank is located below the drain hole, and the other end of the circulation pipe is connected to the water tank.

[0008] The effect achieved by the above components is that the coolant filtered by the brush can flow into the water tank, and the water pump can be started to realize the circulation of the coolant.

[0009] Preferably, a mounting rod is fixedly connected to the surface of the water tank, a mounting ring is fixedly connected to the lower end of the mounting rod, a motor is fixedly installed on the inner side of the mounting ring, and the output end of the motor is fixedly connected to the drive shaft.

[0010] The aforementioned components achieve the following effect: starting the motor enables the drive shaft to rotate, thereby enabling the transmission of the conveyor belt.

[0011] Preferably, the combing and collecting structure includes a fixed frame fixedly connected to the side wall of the water tank and the water trough, a combing plate is slidably installed on the inner side of the fixed frame, and a combing strip is fixedly connected to the side of the combing plate near the brush rod, the combing strip having an arc-shaped structure.

[0012] The above-mentioned components achieve the following effects: the combing strip can not only comb the bristles, but also collect and scrape away the abrasion residue between the bristles.

[0013] Preferably, a positioning block is fixedly connected to the upper side of the combing plate, and a first driving rod is threadedly inserted into the inside of the fixing frame, and the first driving rod and the positioning block are rotatably connected internally.

[0014] The effect achieved by the above components is that by rotating the first drive rod, the carding plate can be driven, thereby enabling flexible use of the carding plate.

[0015] Preferably, a collection hopper is fixedly connected to the lower end of the fixed frame, and the collection hopper has a rectangular opening at the top and a circular opening at the bottom.

[0016] The effect achieved by the above-mentioned components is that the collection hopper facilitates the collection of grinding residue after cleaning.

[0017] Preferably, the lower end of the collecting hopper is fixedly connected to a threaded port, and a threaded cap is threadedly connected to the outer side of the threaded port.

[0018] The aforementioned components achieve the following effect: by opening the threaded cover, the grinding residue collected inside the collection hopper can be periodically processed.

[0019] Preferably, the side wall of the driven shaft is provided with a control structure, the control structure including a first toothed ring fixedly connected to the side wall of the driven shaft, a second toothed ring fixedly connected to the side wall of the brush rod, a limit strip fixedly connected to the side wall of the water tank, a positioning strip slidably connected to the side wall of the limit strip, a pivot pin rotatably connected inside the positioning strip, and a gear fixedly connected to the end side of the pivot pin, the tooth surfaces of the gear meshing with the first toothed ring and the second toothed ring respectively.

[0020] The above components achieve the following effect: by sliding the positioning bar on the limit bar, the gear is moved to a position where the first gear ring and the second gear ring are on the same horizontal plane. When the driven shaft rotates, it can drive the gear to move, which in turn drives the second gear ring and the brush rod to move. This not only achieves deep cleaning of the conveyor belt, but also allows the brush rod to move relative to the combing plate, which facilitates the handling of grinding residue between the bristles.

[0021] Preferably, a second drive rod is threaded into the internal part of the positioning bar, and the second drive rod is rotatably connected to the inside of the water tank. The effect achieved by this component is that rotating the second drive rod facilitates flexible movement of the positioning bar.

[0022] The polishing process of a multi-station integrated grinding and polishing equipment for optical lenses includes the following steps: S1: During the optical lens polishing process, the water pump is started, and the water pump will drive the coolant through the flexible pipe to pour it onto the polishing position to cool it down. S2: Start the motor. At this time, the conveyor belt will run, transporting the grinding residue to the brush position for filtration. S3: Move the gear to a position on the same horizontal plane as the two gear rings, so that the brush rod can rotate synchronously during the rotation of the driven shaft; S4: Finally, the polishing residue will be scraped and collected by the combing plate, realizing the centralized treatment of polishing residue.

[0023] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the design of a cleaning and filtration structure, utilizes a conveyor belt to collect and transport grinding debris such as glass powder and abrasive particles washed down by the coolant during the optical lens polishing process. Combined with brush rods and bristles located at the lower side of the conveyor belt, it achieves primary filtration of the coolant. Simultaneously, it automatically cleans debris adhering to the conveyor belt surface, effectively preventing debris accumulation and dirt buildup at the bottom of the water tank. The filtered coolant flows into the lower water tank and can be recycled via a water pump, significantly extending the coolant's lifespan and reducing processing costs. Furthermore, it reduces the risk of debris scratching the lens surface and accelerating mold wear during coolant circulation, ensuring the processing accuracy and yield of optical lenses.

[0024] This invention features a combing and collection structure that uses arc-shaped combing strips in conjunction with a rotating brush rod to automatically comb the bristles and scrape away abrasion debris stuck in the gaps between the bristles. This effectively prevents the bristles from losing their filtering effect due to debris blockage. The scraped-off debris can be collected in a collection hopper. With the detachable design of the threaded opening and threaded cap, the regular cleaning and transfer of debris can be completed without stopping the machine and disassembling the equipment. This significantly reduces the difficulty and time required for equipment maintenance and improves overall processing efficiency.

[0025] This invention, through a control structure, utilizes the power inherent in the driven shaft and the meshing transmission of gears and two gear rings to achieve synchronous operation of the brush rod and conveyor belt. This eliminates the need for a separate drive motor for the brush rod, simplifying the equipment structure and reducing manufacturing costs and operating energy consumption. Furthermore, the engagement and disengagement of the gears can be controlled by rotating the second drive rod, allowing for flexible switching of the brush rod's working state according to actual processing needs. The transmission can be disconnected when cleaning is not required, reducing unnecessary component wear and extending the equipment's service life. Attached Figure Description

[0037] The positioning bar 95 has a second drive rod 96 inserted into its internal thread, and the second drive rod 96 is rotatably connected to the water tank 2.

[0038] A polishing process for a multi-station integrated grinding and polishing equipment for optical lenses includes the following steps: S1: During the optical lens polishing process, water pump 5 is started. Water pump 5 will drive coolant through the tough tube 4 to pour it onto the polishing position to cool it down. S2: Start motor 707. At this time, conveyor belt 701 will run, transporting the grinding residue to brush bristle 705 for filtration. S3: Move gear 93 to a position on the same horizontal plane as the two gear rings. During the rotation of driven shaft 706, brush rod 704 can be driven to rotate synchronously. S4: Finally, the polishing residue will be scraped and collected by the combing plate 87, realizing the centralized treatment of polishing residue.

[0039] Working principle: When using this multi-station integrated grinding and polishing equipment for optical lenses, the optical lens to be processed is first fixed on the grinding table 11. The equipment is started to perform rough grinding, fine grinding and polishing processes in sequence. During the processing, the water pump 5 is started. The water pump 5 draws coolant from the water tank 702 and delivers it to the connecting pipe 3 through the circulation pipe 6. Then, it is precisely poured into the processing position of each grinding table 11 through several flexible pipes 4 to cool and lubricate the lens and grinding tool. The glass powder, abrasive particles and other debris generated during grinding are washed into the water tank 2 below.

[0040] Simultaneously, the motor 707 is started, and the motor 707 drives the drive shaft 710 to rotate through the output end. The drive shaft 710, together with the driven shaft 706, drives the conveyor belt 701 to run continuously on the bottom side of the water tank 2, receiving and conveying the polishing debris washed down. When the debris moves to the end side with the conveyor belt 701, it will fall into the gap of the bristles 705 on the brush bar 704 at the lower angle. The coolant then flows through the gap of the bristles 705 and the drain hole 703 into the water tank 702 below, completing the first-stage filtration and circulation of the coolant.

[0041] When it is necessary to clean the bristles 705 or improve the filtration effect, rotate the second drive rod 96. The second drive rod 96 drives the positioning strip 95 to slide along the limiting strip 94 through the threaded transmission, so that the gear 93 on the end side of the pivot pin 97 moves to a position on the same horizontal plane as the first gear ring 91 and the second gear ring 92. At this time, the gear 93 meshes with the two gear rings at the same time. When the driven shaft 706 rotates, it will drive the first gear ring 91 to rotate synchronously. Then, through the transmission of the gear 93, it will drive the second gear ring 92 and the brush rod 704 to rotate. The rotating bristles 705 can not only further intercept the fine debris in the coolant, but also scrape off the stubborn debris adhering to the surface of the conveyor belt 701 in the opposite direction, so as to achieve deep cleaning of the conveyor belt 701.

[0042] During the rotation of the brush rod 704, the first drive rod 85 is rotated. The first drive rod 85 drives the combing plate 87 to move along the fixed frame 81 towards the brush rod 704 through the positioning block 86, so that the arc-shaped combing strip 88 fits against the rotating bristles 705. The combing strip 88 automatically combs the bristles 705 and scrapes off the grinding residue stuck in the gaps between the bristles 705. The scraped residue naturally falls into the collection hopper 82 below for collection. When the residue in the collection hopper 82 accumulates to a certain amount, the threaded cover 84 can be unscrewed to discharge the residue. After processing, the threaded cover 84 can be tightened again to continue use. After processing is completed, the motor 707 and water pump 5 are turned off in sequence. If the equipment is not used for a long time, the second drive rod 96 can be rotated in the opposite direction to separate the gear 93 from the two gear rings and stop the operation of the brush rod 704, reducing the wear of idle parts.
