Description

Technical Field

[0001] This invention belongs to the field of optical lens processing technology, specifically a lens cutting device and cutting method for optical lenses. Background Technology

[0002] Optical lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. Qualified glass blocks are then heated and forged to form optical lens blanks. In the process of optical lens processing, laser cutting is usually used. Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short time. The material begins to vaporize, forming steam. This steam is ejected at a high speed, and at the same time as the steam is ejected, a cut is formed on the material.

[0003] In existing technologies, during the cutting process of optical lenses, the operator first places the optical lens on the cutting table, then cuts it. After the cutting is completed, the optical lens is removed from the cutting table, and the cutting table is cleaned before a new optical lens can be placed on it for the next cutting. This prolongs the cutting time of optical lenses, requiring more working time and increasing costs. In addition, the debris generated during the cutting process adheres to the optical lens, which can easily scratch the optical lens during transfer and other operations. Furthermore, the harmful gases and chemicals generated during laser cutting can pollute the working environment and harm the health of the workers.

[0004] Therefore, we propose a lens cutting device and method for optical lenses to solve the problems encountered above. Summary of the Invention

[0005] The purpose of this invention is to address the problems in the optical lens cutting process. In this process, workers first place the optical lens on the cutting table, then cut it. After cutting, the optical lens is removed from the cutting table, and the table is cleaned before a new optical lens can be placed for the next cut. This process prolongs the cutting time, increases costs, and causes debris to adhere to the optical lens, potentially scratching it during transport. Furthermore, the harmful gases and chemicals generated during laser cutting pollute the working environment and harm workers' health. Therefore, this invention proposes a lens cutting device and method for optical lenses.

[0006] The objective of this invention can be achieved through the following technical solution: A workbench is included, with a column at the lower end of the rear outer wall of the workbench. A laser cutting device is mounted on the lower surface of the front end of the column. An alternating feeding mechanism is mounted above the workbench, and two sets of the alternating feeding mechanism are arranged in a horizontal array. The alternating feeding mechanism includes a U-shaped track plate, and two U-shaped track plates are provided. The two U-shaped track plates are respectively mounted on the outer surfaces of the front and rear sides of the workbench. A rotating plate is mounted on the outer surface of each of the two U-shaped track plates. A sliding push block is slidably installed inside the rotating plate. A positioning shaft is rotatably installed inside the sliding push block. A lifting rod is mounted on the upper end of the positioning shaft. A sleeve rod is sleeved on the upper end of the lifting rod. A horizontal plate is fixedly connected to the upper end of the sleeve rod through a Z-shaped connecting plate. A placement platform is provided between the two horizontal plates.

[0007] In a preferred embodiment of the present invention, a ball bearing is rotatably mounted on one end of the positioning shaft near the worktable, and the ball bearing is disposed inside the U-shaped movable groove of the U-shaped track plate. A sliding groove and a moving groove are provided on the upper surface of the worktable. A limiting slider is slidably mounted inside the sliding groove, and the upper end of the limiting slider is connected to the horizontal plate. A roller is provided inside the moving groove, and the upper end of the roller is connected to the lower surface of the placement platform.

[0008] In a preferred embodiment of the present invention, a drive mechanism is provided inside the workbench. The drive mechanism includes a motor, which is mounted on the left outer wall of the workbench via a motor mount. A worm gear is connected to the power output end of the motor. A worm wheel is meshed at the upper end of the worm gear. There are two worm wheels. A rotating shaft is provided between the two worm wheels. Both ends of the rotating shaft pass through the workbench and the U-shaped track plate and extend to the outside. A rotating plate is provided on the circumferential surface of the outer end of the rotating shaft.

[0009] In a preferred embodiment of the present invention, the workbench is provided with a processing mechanism, which includes an air pump and is located at the rear of the middle of the workbench. The front end of the air pump is provided with an air intake pipe and the rear end of the air pump is provided with an exhaust pipe. A water tank is provided at the rear of the column. The rear end of the exhaust pipe passes through the workbench and the column and extends to the bottom of the water tank. An activated carbon adsorption mesh is provided inside the upper end of the water tank.

[0010] In a preferred embodiment of the present invention, a dust removal mechanism is provided above the suction pipe. The dust removal mechanism includes a sealing connector, and a sealing ring is provided on the outer surface of the upper end of the sealing connector. A connection port is provided inside the lower end of the placement platform. A dust extraction pipe is connected to the upper end of the connection port, and the upper end of the dust extraction pipe passes through the placement platform and extends to the top of the placement platform. The upper end of the sealing connector is inserted into the connection port. Limiting plates are provided on the outer surfaces of both the left and right sides of the sealing connector. A spring is provided on the lower surface of the limiting plate, and both the limiting plate and the spring are provided inside the upper end of the worktable. The lower end of the sealing connector is connected to the upper end of the suction pipe through a corrugated pipe.

[0011] As a preferred embodiment of the present invention, a lens cutting method for optical lenses specifically includes the following steps:

[0012] Step 1: Place the optical lens to be cut on the upper surface of the left placement platform, then start the motor. The motor drives the worm gear to rotate, which in turn drives the worm wheel and the rotating shaft to rotate, which in turn drives the rotating plate on the surface of the rotating shaft to rotate. When the rotating plate rotates upward, the sliding push block and the positioning shaft will move a short distance to the right inside the rotating plate. At the same time, the lifting rod moves into the sleeve rod under the push of the positioning shaft. After the positioning shaft moves to the upper left end of the U-shaped track groove, the rotating plate continues to rotate. The positioning shaft will move horizontally to the right under the drive of the rotating plate. Then, through the lifting rod, the sleeve rod, the U-shaped connecting plate and the horizontal plate, the placement platform is smoothly moved horizontally to the right. When both the left and right positioning shafts have moved to the upper right end of the U-shaped track groove, the right placement platform moves to the right end of the upper surface of the worktable, and the left placement platform carrying the optical lens moves to the bottom of the laser cutting equipment.

[0013] Step 2: When the right-side placement platform moves to the right, its lower end will press down on the sealing connector, causing the sealing connector to move out of its connection port. Then, when the left-side placement platform moves to contact the sealing connector, it will also press the sealing connector down into the worktable. Then, when the left-side placement platform moves directly under the laser cutting equipment, the spring force on the side wall of the sealing connector is released, pushing the upper end of the sealing connector upward into the connection port, so that the dust extraction pipe is connected to the suction pipe through the sealing connector.

[0014] Step 3: Next, as the positioning axis moves from the upper right end of the U-shaped track groove to the lower right end, start the laser cutting equipment and air pump. The positioning axis will not move the placement table horizontally; it will only move the lifting rod out of the sleeve rod. During this process, the laser cutting equipment will cut the optical lens below it. The cutting work is completed before the positioning axis moves to the lower right end of the U-shaped track groove. At the same time, during the cutting process, the air pump works to draw in air through the suction pipe, so that the dust extraction pipe can absorb the debris and gas generated during the cutting process. Then, it is discharged into the water tank through the exhaust pipe, so that the debris dissolves into the water. At the same time, when the gas is discharged from the water tank, it is treated by the activated carbon filter, which can remove some harmful substances and prevent the debris generated during the cutting process from adhering to the lens and damaging the lens, or the gas from drifting into the working environment and causing environmental pollution.

[0015] Step 4: During the optical lens cutting process on the left placement stage, if there is a cut optical lens on the upper surface of the right placement stage, remove it. Then place a new optical lens waiting to be cut on the upper surface of the right placement stage and wait for the optical lens on the left placement stage to be cut before replacing it, so that the optical lenses can be cut alternately.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) By setting up an alternating feeding mechanism, when the optical lens on one placement table is being cut, the cut optical lens can be removed, the placement table can be cleaned, and a new optical lens can be placed on another placement table. This allows the optical lens cutting to be carried out alternately and seamlessly, improving the overall work efficiency and reducing the processing cost.

[0018] (2) Through the set processing mechanism and dust removal mechanism, the debris, harmful gases and chemicals generated during the cutting process can be absorbed, avoiding debris from adhering to the lens and causing scratches to the lens during subsequent transfer and other operations. It also avoids harmful gases and chemicals from drifting in the working environment, polluting the working environment and harming the health of the staff. Attached Figure Description

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figure 1 - Figure 6As shown, a lens cutting device for optical lenses includes a worktable 1. A column 6 is provided at the lower end of the rear outer wall of the worktable 1. A laser cutting device 7 is provided on the lower surface of the front end of the column 6. The laser cutting device 7 is an existing device and will not be described in detail here. A drive mechanism 2 is provided inside the worktable 1. The drive mechanism 2 includes a motor 201, which is mounted on the left outer wall of the worktable 1 via a motor mount. The power output end of the motor 201 is connected to a worm gear 202 via a coupling. The upper end of the worm gear 202 is meshed with a worm wheel 203. There are two worm wheels 203. A rotating shaft 204 is provided between the two worm wheels 203. The front and rear ends of the rotating shaft 204 pass through the worktable 1 and the U-shaped track plate 301 and extend to the outside. An alternating feeding mechanism 3 is provided above the worktable 1. Two sets of alternating feeding mechanisms 3 are arranged in a horizontal array. The alternating feeding mechanism 3 includes two U-shaped track plates 301. Two U-shaped track plates 301 are respectively disposed on the outer surfaces of the front and rear sides of the worktable 1. A rotating plate 302 is disposed on the outer surface of each U-shaped track plate 301. The rotating plate 302 is disposed on the circumferential surface of the outer end of the rotating shaft 204. A sliding push block 303 is slidably installed inside the rotating plate 302. A positioning shaft 304 is rotatably installed inside the sliding push block 303. A ball bearing 8 is rotatably installed at the end of the positioning shaft 304 closest to the worktable 1, and the ball bearing 8 is disposed on the U-shaped track plate 301. Inside the U-shaped movable groove, a lifting rod 305 is provided at the upper end of the positioning shaft 304. A sleeve rod 306 is sleeved at the upper end of the lifting rod 305. A horizontal plate 308 is fixedly connected to the upper end of the sleeve rod 306 through a U-shaped connecting plate 307. The U-shaped connecting plate 307 is provided so that the rotating plate 302 will not contact the U-shaped connecting plate 307 when it rotates to the upper end, thereby allowing the rotating plate 302 to rotate smoothly and stably. A placement platform 309 is provided between the two horizontal plates 308.

[0030] It should be noted that there is a certain distance between the column 6 and the rear side of the worktable 1, so that the rotating plate 302 will not collide with the column 6 when it rotates. The inside of the U-shaped track plate 301 is provided with a U-shaped track groove, and the inner end of the positioning shaft 304 is movably installed inside the U-shaped track groove through the ball bearing 8. This allows the positioning shaft 304 to move smoothly inside the U-shaped track groove when the rotating plate 302 rotates and drives the positioning shaft 304 to move. In turn, the positioning shaft 304 can smoothly drive the lifting rod 305 and the sleeve rod 306 to move horizontally left and right. The inside of the rotating plate 302 is provided with a movable groove, and the sliding push block 303 is slidably installed inside the movable groove. This design allows the sliding push block 303 to slide inside the movable groove when the rotating plate 302 rotates, preventing the sliding push block 303 from getting stuck. This allows the sliding push block 303 to smoothly drive the lifting rod 305 and the sleeve rod 306 to move horizontally via the positioning shaft 304. When the positioning shaft 304 moves to the inside of the left and right sides of the U-shaped track groove, and the positioning shaft 304 moves vertically inside the U-shaped track groove, the lifting rod 305 will rise and fall vertically inside the sleeve rod 306. Consequently, it will not drive the horizontal plate 308 and the placement platform 309 to move vertically via the sleeve rod 306 and the U-shaped connecting plate 307, so that the placement platform 309 can only move horizontally left and right.

[0031] The upper surface of the workbench 1 is provided with a sliding groove 10 and a moving groove 11. A limiting slider 9 is slidably installed inside the sliding groove 10, and the upper end of the limiting slider 9 is connected to the horizontal plate 308. The setting of the sliding groove 10 provides the limiting slider 9 with a space for movement, so that the horizontal plate 308 can smoothly drive the limiting slider 9 to move horizontally. The moving groove 11 is provided with a roller 12, and the upper end of the roller 12 is connected to the lower surface of the placement table 309. The setting of the moving groove 11 provides the roller 12 with a space for movement, so that the roller 12 can smoothly move horizontally inside the moving groove 11.

[0032] It should be noted that the setting of the limiting slider 9 can limit the horizontal plate 308 and the placement table 309, so that when the horizontal plate 308 and the placement table 309 are subjected to a vertical force, they will not move vertically due to the vertical force. The lower surface of the placement table 309 does not contact the upper surface of the worktable 1, so that the lower end of the placement table 309 contacts the worktable 1 through the roller 12. Then, when the horizontal plate 308 drives the placement table 309 to move horizontally, the placement table 309 will not generate a lot of friction with the worktable 1, thus making the horizontal movement of the placement table 309 more stable and smooth.

[0033] The workbench 1 is equipped with a processing mechanism 4, which includes an air pump 401. The air pump 401 is located at the rear of the middle of the workbench 1. The front end of the air pump 401 is equipped with an air suction pipe 402, and the rear end of the air pump 401 is equipped with an exhaust pipe 403. The rear side of the column 6 is equipped with a water tank 404. The rear end of the exhaust pipe 403 passes through the workbench 1 and the column 6 and extends to the bottom of the water tank 404. The upper end of the water tank 404 is equipped with an activated carbon adsorption net 405.

[0034] It should be noted that clean water is injected into the water tank 404 before operation, so that the water overflows the exhaust port of the exhaust pipe 403. Then, the gas discharged from the exhaust pipe 403 will directly enter the clean water, so that impurities in the gas will directly enter the water, preventing impurities from being carried by the gas and dispersed into the air. The activated carbon adsorption net 405 can further purify the gas after removing impurities, adsorbing harmful gases and chemicals in the gas, thereby making the discharged gas purer and avoiding pollution of the working environment and harm to the health of the staff.

[0035] A dust removal mechanism 5 is installed above the suction pipe 402. The dust removal mechanism 5 includes a sealing connector 501, and a sealing ring is provided on the outer surface of the upper end of the sealing connector 501. The sealing ring improves the sealing effect of the sealing connector 501, preventing air leakage at the connection point and improving the dust extraction effect. A connection port 502 is opened inside the lower end of the placement platform 309. A dust extraction pipe 503 is connected to the upper end of the connection port 502, and the upper end of the dust extraction pipe 503 passes through the placement platform 309 and extends to the top of the placement platform 309, forming a sealed connection. The upper end of the sealing connector 501 is inserted into the inside of the connector 502. Limiting plates 504 are provided on the outer surfaces of both sides of the sealing connector 501. Springs 505 are provided on the lower surface of the limiting plates 504. Both the limiting plates 504 and the springs 505 are located inside the upper end of the workbench 1. The lower end of the sealing connector 501 is connected to the upper end of the suction pipe 402 through a bellows 506. The bellows 506 allows the sealing connector 501 to move smoothly in the vertical direction without detaching from the suction pipe 402.

[0036] It should be noted that the outer surface of the upper end of the sealing connector 501 and the left and right sides of the bottom of the placement platform 309 are both arc-shaped, so that when the placement platform 309 moves horizontally left and right, the sealing connector 501 can be pushed downward smoothly, thereby allowing the sealing connector 501 to be smoothly disengaged and inserted.

[0037] Example 2:

[0038] Please refer to the following: Figure 1 - Figure 6As shown, the present invention further discloses a lens cutting method for optical lenses, which specifically includes the following steps:

[0039] Step 1: Place the optical lens to be cut on the upper surface of the left placing table 309, then start the motor 201. The motor 201 operates to drive the worm 202 to rotate, which in turn drives the worm wheel 203 and the rotating shaft 204 to rotate, and further drives the rotating plate 302 on the surface of the rotating shaft 204 to rotate. When the rotating plate 302 rotates upward, the sliding push block 303 and the positioning shaft 304 will move a small distance to the right inside the rotating plate 302, and at the same time, the lifting rod 305 is pushed by the positioning shaft 304 to move into the interior of the sleeve rod 306. After the positioning shaft 304 moves to the upper left end of the track groove of the rectangular track plate 301, when the rotating plate 302 continues to rotate at this time, the positioning shaft 304 will be driven by the rotating plate 302 to move horizontally to the right, and then smoothly drive the placing table 309 to move horizontally to the right through the lifting rod 305, sleeve rod 306, several-shaped connecting plate 307 and horizontal plate 308. When both the left and right sets of positioning shafts 304 move to the upper right end of the rectangular track groove, the right placing table 309 moves to the right end of the upper surface of the workbench 1, and the left placing table 309 carrying the optical lens moves directly below the laser cutting equipment 7;

[0040] Step 2: When the right placing table 309 moves to the right, its lower end presses down the sealing connector 501, causing the sealing connector 501 to move out of its connection port 502. Then when the left placing table 309 moves into contact with the sealing connector 501, it will first press the sealing connector 501 down into the interior of the workbench 1. Next, when the left placing table 309 moves directly below the laser cutting equipment 7, the elastic force of the spring 505 on the side wall of the sealing connector 501 is released, pushing the upper end of the sealing connector 501 upward into the interior of the connection port 502, so that the dust extraction pipe 503 communicates with the air suction pipe 402 through the sealing connector 501;

[0041] Step 3: Next, as the positioning shaft 304 moves from the upper right end to the lower right end of the U-shaped track groove, the laser cutting equipment 7 and the air pump 401 are started. The positioning shaft 304 will not move the placement table 309 horizontally, but will only move the lifting rod 305 out of the sleeve rod 306. Then, during this process, the laser cutting equipment 7 will cut the optical lens below it. The cutting work is completed before the positioning shaft 304 moves to the lower right end of the U-shaped track groove. At the same time, during the cutting process, the air pump 401 works to draw air through the suction pipe 402, so that the dust extraction pipe 503 can absorb the debris and gas generated during the cutting process. Then, it is discharged into the water tank 404 through the exhaust pipe 403, so that the debris dissolves into the water. At the same time, when the gas is discharged from the water tank 404, it is treated by the activated carbon adsorption net 405, which can remove some harmful substances, so as to prevent the debris generated during the cutting process from adhering to the lens and damaging the lens, or the gas from drifting into the working environment and causing environmental pollution.

[0042] Step 4: During the optical lens cutting process above the left placement stage 309, if there is a cut optical lens on the upper surface of the right placement stage 309, remove it. Then place a new optical lens waiting to be cut on the upper surface of the right placement stage 309 and wait for the optical lens on the left placement stage 309 to be cut before replacing it, so that the optical lenses can be cut alternately.

[0043] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.

The motor (201) drives the worm gear (202) to rotate, which in turn drives the worm wheel (203) and the rotating shaft (204) to rotate, which in turn drives the rotating plate (302) on the surface of the rotating shaft (204) to rotate. When the rotating plate (302) rotates upward, the sliding push block (303) and the positioning shaft (304) will move a small distance to the right inside the rotating plate (302). At the same time, the lifting rod (305) moves into the sleeve rod (306) under the push of the positioning shaft (304). When the positioning shaft (304) moves to After the upper left end of the track groove of the U-shaped track plate (301), when the rotating plate (302) continues to rotate, the positioning shaft (304) will move horizontally to the right under the drive of the rotating plate (302), and then smoothly drive the placement platform (309) to move horizontally to the right through the lifting rod (305), sleeve rod (306), zig-shaped connecting plate (307) and horizontal plate (308). When both the left and right positioning shafts (304) have moved to the upper right end of the U-shaped track groove, the right placement platform (309) moves to the right end of the upper surface of the worktable (1), and the left placement platform (309) carries the optical lens to move directly below the laser cutting equipment (7). Step 2: When the right placement platform (309) moves to the right, its lower end will press down on the sealing connector (501), causing the sealing connector (501) to move out of its connection port (502). Then, when the left placement platform (309) moves to contact the sealing connector (501), the sealing connector (501) is first pressed down into the inside of the worktable (1). Then, when the left placement platform (309) moves directly below the laser cutting equipment (7), the spring (505) on the side wall of the sealing connector (501) is released, pushing the upper end of the sealing connector (501) upward into the inside of the connection port (502), so that the dust extraction pipe (503) is connected to the suction pipe (402) through the sealing connector (501). Step 3: Next, as the positioning shaft (304) moves from the upper right end to the lower right end of the U-shaped track groove, the laser cutting equipment (7) and air pump (401) are started. The positioning shaft (304) will not drive the placement table (309) to move horizontally, but will only cause the lifting rod (305) to move out of the sleeve rod (306). Then, during this process, the laser cutting equipment (7) cuts the optical lens below it. Before the positioning shaft (304) moves to the lower right end of the U-shaped track groove, the cutting work is completed. At the same time, during the cutting process, the air pump (401) works to draw air through the suction pipe (402), so that the dust extraction pipe (503) can absorb the debris and gas generated during the cutting process. Then, the dust is discharged into the water tank (404) through the exhaust pipe (403), so that the debris dissolves into the water. At the same time, when the gas is discharged from the water tank (404), it is treated by the activated carbon filter (405). Step 4: During the optical lens cutting process above the left placement stage (309), if there is a cut optical lens on the upper surface of the right placement stage (309), remove it, and then place a new optical lens waiting to be cut on the upper surface of the right placement stage (309). Replace it after the optical lens on the left placement stage (309) is cut, so that the optical lenses can be cut alternately.
