[0004] However, the current cutting device has the following problems: the cutting device is not convenient for fixing and positioning optical lens blanks of different specifications and sizes, resulting in a lot of time wasted on positioning and fixing the optical lens blanks, affecting the processing efficiency and making the device less applicable. Therefore, we propose a cutting and positioning device for processing optical lenses. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cutting and positioning device for processing optical lenses, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for processing optical lens cutting and positioning, including a device body, an adjustment component is arranged on the upper part of the inside of the device body, a laser cutting machine body is fixed to the movable end of the adjustment component, a positioning device is arranged in the middle of the device body, and the positioning device includes a driving motor, a turntable, and an electric push rod.

Three strip grooves are evenly opened on the top circumference of the turntable, and T-shaped columns are slidably installed inside the three strip grooves of the turntable. The bottom of the T-shaped column is hinged with a hinged rod, and one end of the hinged rod away from the T-shaped column is hinged to the top of the telescopic end of the electric push rod. The telescopic end of the electric push rod drives one end of the hinged rod to move downward, and the hinged rod pulls the T-shaped column to move toward the center of the turntable, and the T-shaped column clamps and fixes the optical lens blank.

[0007] According to the above technical solution, the adjustment component includes two fixed shells, and the two fixed shells are respectively fixed on both sides of the inner wall of the device body, and a screw rod 1 is rotatably installed inside one of the fixed shells, and the screw rod 1 is driven by a motor, and the external thread of the screw rod 1 is connected to a movable plate, and the end of the movable plate away from the screw rod 1 is slidably installed inside the other fixed shell, and the movable plate is the movable end of the adjustment component. The specific working process of the adjustment component is that the screw rod 1 is driven to rotate by the motor, and the screw rod 1 will drive the movable plate to move between the two fixed shells, so that the movable plate can adjust the position of the laser cutting machine body.

[0008] The U-shaped lever is pivotally attached to the bottom of the T-shaped post and is slidably mounted thereon, and a spring is arranged between the U-shaped lever and the bottom of the T-shaped post, a clamping column is fixed to the bottom of the U-shaped lever, a ladder panel is transversely inserted through and slidably mounted on one side of each T-shaped post close to the center of the turntable, and a spring is arranged between the ladder panel and the outer wall of the T-shaped post, a slot plate is fixed to the bottom of the U-shaped lever, a slot plate is transversely fixed to the bottom of the turntable, a slope is arranged on the top of the ladder panel close to the center of the turntable, the top of the inner wall of the U-shaped lever is located on the sloped motion trajectory of the ladder panel, and three clamping columns are fixed on both sides of the top of the clamping column The U-shaped plug rod drives the clamping column to move upward, and the U-shaped plug rod drives the clamping column to move upward until the triangular block of the clamping column is inserted into the slot of the slot plate. The slot plate limits the position of the T-shaped column through the clamping column, so that when the electric push rod applies tension to the T-shaped column through the hinge rod, the T-shaped column cannot be displaced.

[0009] The two ends of the two-way telescopic rod are fixed with an L-shaped column rod, one end of the L-shaped column rod is slidably mounted in the Z-shaped groove of the Z-shaped groove plate, and the other end of the L-shaped column rod is fixed with a scraper rod at the bottom. The side of the scraper rod close to the center of the turntable is set with a rough surface. When the T-shaped column moves toward the center of the turntable, the T-shaped column will also drive the scraper rod to move. After the scraper rod contacts the outer wall of the optical lens blank, the scraper rod will drive the L-shaped column rod to slide along the Z-shaped groove of the Z-shaped groove plate, and the L-shaped column rod drives the two-way telescopic rod to move. The spring corresponding to the two-way telescopic rod is compressed. Under the joint restriction of the Z-shaped groove of the Z-shaped groove plate and the two-way telescopic rod, the L-shaped column rod will move along the outer wall of the optical lens blank toward the two sides of the T-shaped column during the movement, so that the L-shaped column rod drives the scraper rod to scrape foreign matter adhered to the outer wall of the optical lens blank.

[0010] According to the above technical solution, an anti-reflection device is arranged under the movable plate, and the anti-reflection device includes an elastic telescopic rod, which is fixed at the outer wall of the movable plate, and a connecting rod is fixed at the bottom of the elastic telescopic rod, and a screw rod 2 is rotatably installed at the outer wall of the fixed end of the elastic telescopic rod, and a threaded block is fixed at one end of the connecting rod, and the threaded block is threadedly connected to the outside of the screw rod 2, and a fixed cylinder is fixed at the other end of the connecting rod, and grinding blocks are fixed on both sides of the bottom of the fixed cylinder, and a retaining cylinder is fixed at the inner wall of the fixed cylinder.

In the process of the turntable driving the optical lens blank to rotate, the grinding block will roughen the part of the optical lens blank that is in the cutting track of the laser cutting machine body.

[0011] According to the above technical solution, a U-shaped frame is fixed on both sides of the fixed cylinder, a rotating wheel is rotatably installed inside the U-shaped frame, a number of fan blades are evenly fixed on the outer circumference of the rotating shaft of the rotating wheel, the outer side of the rotating wheel is set as a smooth surface, and the bottoms of the fixed cylinder, the retaining cylinder and the rotating wheel are located on the same horizontal plane. When the optical lens blank is located in the cutting track of the laser cutting machine body and is roughened, the rotating wheel can rotate under the action of the friction between the rough surface of the optical lens blank and the rotating wheel. During the rotation of the rotating wheel, the rotating shaft of the rotating wheel will drive the fan blades to rotate.

[0012] The present invention provides a cutting and positioning device for processing optical lenses. It has the following beneficial effects:

[0013] (1) The present invention sets a positioning device so that the electric push rod and the hinged rod can cooperate to adjust the position of the T-shaped column according to the size of the optical lens blank. This movement mode enables the T-shaped column to position and fix optical lens blanks of different sizes; at the same time, the T-shaped column, ladder panel, U-shaped plug rod, U-shaped plug rod, clamping column, and slot plate cooperate to limit the position of the T-shaped column, so that when the electric push rod applies a pulling force to the T-shaped column through the hinged rod, the T-shaped column cannot be displaced, thereby avoiding the hinged rod pulling the T-shaped column to apply excessive clamping force to the optical lens blank. The characteristics of the optical lens require that the positioning during the processing process must be very precise. Excessive clamping may cause slight deformation of the lens near the clamping area, which will affect the working path of the laser cutting machine body and cause a decrease in cutting accuracy. If the optical lens blank is slightly bent or twisted, the focus of the laser cutting machine body will deviate from the predetermined position, resulting in problems such as an uneven cutting line and an uneven cutting surface.

[0014] (2) The present invention sets an anti-deviation device so that the T-shaped column, scraper rod, L-shaped column rod, Z-shaped groove plate, and bidirectional telescopic rod cooperate to drive the scraper rod to scrape foreign matter adhered to the outer wall of the optical lens blank, thereby helping the T-shaped column to firmly fix the optical lens blank in the correct position, thereby avoiding the presence of foreign matter, causing the optical lens blank to undergo slight displacement during the clamping process, and affecting the precision processing operation of laser cutting.

[0015] (3) The present invention sets an anti-reflection device so that the T-shaped column, screw rod 2, connecting rod, fixed cylinder, grinding block, and elastic telescopic rod cooperate to drive the grinding block to roughen the part of the optical lens blank that is on the cutting track of the laser cutting machine body. The rough surface of the optical lens blank will scatter the reflected light of the laser beam of the laser cutting machine body, instead of reflecting the laser back to the device like a smooth mirror. This can reduce the energy reflected back to the laser source, thereby reducing the risk of equipment damage. At the same time, the rough surface of the optical lens blank can promote the scattering and absorption of laser energy. The laser will have more heat exchange with the surface, thereby improving the cutting efficiency. At the same time, the blocking cylinder can help shield the area that does not need to be irradiated, avoiding the laser beam from irradiating the part that should not be cut. The blocking cylinder can serve as a physical barrier, allowing the laser beam to focus only on a specific cutting area, preventing The laser beam diffuses to avoid damaging other parts of the optical lens blank; at the same time, under the friction between the rough surface of the optical lens blank and the rotating wheel, the rotating wheel can rotate. The staff can determine whether the part of the optical lens blank in the cutting track of the laser cutting machine body has been polished rough by observing the rotation of the rotating wheel, so as to determine whether to start the laser cutting machine body to perform laser cutting on the optical lens blank. During the rotation of the rotating wheel, the rotating shaft of the rotating wheel will drive the fan blades to rotate. During the laser cutting process of the optical lens blank, the temperature of the cutting point is extremely high, and the surface of the optical lens blank is prone to melting or burning due to heat accumulation. The fan blades drive the surrounding air flow by rotation, which helps to dissipate heat, reduce the temperature of the cutting area, and reduce the heat-affected area on the lens surface, thereby improving the cutting quality and preventing damage or deformation of the optical lens surface.

The bottom of the T-shaped column 46 is hinged with a hinge rod 45, and one end of the hinge rod 45 away from the T-shaped column 46 is hinged to the top of the telescopic end of the electric push rod 44. Through the arrangement of the above structure, the position of the T-shaped column 46 can be adjusted according to the size of the optical lens blank. This movement mode enables the T-shaped column 46 to position and fix optical lens blanks of different sizes. Then, the position of the laser cutting machine body 3 can be adjusted by adjusting the component 2 to enable the laser cutting machine body 3 to cut optical lenses of different cutting diameters.

[0028] The adjustment component 2 includes two fixed shells 21, which are respectively fixed on both sides of the inner wall of the device body 1. A screw 22 is rotatably installed inside one of the fixed shells 21, and the screw 22 is driven by a motor.

The side of the inner wall top of the U-shaped plug rod 49 is located on the inclined motion trajectory of the ladder panel 410, triangular card blocks are fixed on both sides of the top of the clamping column 47, and the bottom of the card slot plate 48 is provided with a plurality of The card slot matched with the triangular card block, through the setting of the above structure, makes the card slot plate 48 limit the position of the T-shaped column 46 through the card column 47, so that when the electric push rod 44 applies a pulling force to the T-shaped column 46 through the hinge rod 45, the T-shaped column 46 cannot be displaced, thereby avoiding the hinge rod 45 pulling the T-shaped column 46 to apply excessive clamping force on the optical lens blank. The characteristics of the optical lens require that the positioning during the processing must be very precise. Excessive clamping may cause slight deformation of the lens near the clamping area, which will affect the working path of the laser cutting machine body 3 and cause a decrease in cutting accuracy. If the optical lens blank is slightly bent or twisted, the focus of the laser cutting machine body 3 will deviate from the predetermined position, resulting in problems such as an uneven cutting line and an uneven cutting surface.

[0030] An anti-bias device 5 is provided above each T-shaped column 46. The anti-bias device 5 includes a fixing plate 51. The fixing plate 51 is fixed to the top of the T-shaped column 46 on one side away from the center of the turntable 43. Z-shaped slot plates 52 are fixed on both sides of the fixing plate 51. A Z-shaped slot is provided on the top of the Z-shaped slot plate 52. A two-way telescopic rod 53 is slidably installed on the top of the fixing plate 51. A spring is provided between the fixed end of the two-way telescopic rod 53 and the fixing plate 51. L-shaped column rods 54 are fixed to the two-way telescopic ends of the two-way telescopic rod 53. One end is slidably installed inside the Z-shaped groove of the Z-shaped groove plate 52, and a scraper rod 55 is fixed to the bottom of the other end of the L-shaped column 54. The side of the scraper rod 55 close to the center of the turntable 43 is set as a rough surface. Through the setting of the above structure, the scraper rod 55 scrapes foreign matter adhered to the outer wall of the optical lens blank, thereby helping the T-shaped column 46 to firmly fix the optical lens blank in the correct position, thereby avoiding the presence of foreign matter, causing the optical lens blank to undergo slight displacement during the clamping process, affecting the precision processing operation of laser cutting.

[0031] When in use, the optical lens blank is placed on the top of the turntable 43, and the optical lens blank is located between the three T-shaped columns 46, and the electric push rod 44 is started. The telescopic end of the electric push rod 44 drives one end of the hinged rod 45 to move downward, and the hinged rod 45 pulls the T-shaped column 46 to move toward the center of the turntable 43. The T-shaped column 46 clamps and fixes the optical lens blank, and the position of the T-shaped column 46 can be adjusted according to the size of the optical lens blank. This movement method enables the T-shaped column 46 to position and fix optical lens blanks of different sizes. Then, the laser can be adjusted by adjusting the component 2. The position of the cutting machine body 3 enables the laser cutting machine body 3 to cut optical lenses with different cutting diameters. The specific working process of the adjustment component 2 is as follows: the screw 22 is driven by the motor to rotate, and the screw 22 will drive the movable plate 23 to move between the two fixed shells 21, so that the movable plate 23 can adjust the position of the laser cutting machine body 3. Finally, the pulley 42 is driven by the driving motor 41 to rotate, and the pulley 42 drives the turntable 43 to rotate through the belt, and the turntable 43 drives the optical lens blank fixed thereon to rotate. The optical lens can be cut by starting the laser cutting machine body 3. The blank is cut; at the same time, when the T-shaped column 46 moves toward the center of the turntable 43, the T-shaped column 46 drives the ladder panel 410 to move with it. After the ladder panel 410 contacts the outer wall of the optical lens blank, as the T-shaped column 46 continues to move, the inclined surface of the ladder panel 410 will push the top of the inner wall of the U-shaped plug 49 to drive the U-shaped plug 49 to move upward, and the U-shaped plug 49 drives the clamping column 47 to move upward until the triangular clamping block of the clamping column 47 is clamped into the clamping groove of the clamping groove plate 48. The clamping groove plate 48 limits the position of the T-shaped column 46 through the clamping column 47, so that the electric push rod 44 When a pulling force is applied to the T-shaped column 46 through the hinged rod 45, the T-shaped column 46 cannot be displaced, thereby preventing the hinged rod 45 from pulling the T-shaped column 46 to apply excessive clamping force to the optical lens blank. The characteristics of the optical lens require that the positioning during the processing process must be very precise. Excessive clamping may cause slight deformation of the lens near the clamping area, which will affect the working path of the laser cutting machine body 3 and cause a decrease in cutting accuracy. If the optical lens blank is slightly bent or twisted, the focus of the laser cutting machine body 3 will deviate from the predetermined position, resulting in problems such as an uneven cutting line and an uneven cutting surface.

[0032] When the T-shaped column 46 moves toward the center of the turntable 43, the T-shaped column 46 will also drive the scraper rod 55 to move with it. After the scraper rod 55 contacts the outer wall of the optical lens blank, the scraper rod 55 will drive the L-shaped column rod 54 to slide in the Z-shaped groove of the Z-shaped groove plate 52. The L-shaped column rod 54 drives the two-way telescopic rod 53 to move with it. The spring corresponding to the two-way telescopic rod 53 is compressed. Under the joint restriction of the Z-shaped groove of the Z-shaped groove plate 52 and the two-way telescopic rod 53, the L-shaped column rod 54 will move along the outer wall of the optical lens blank toward the two sides of the T-shaped column 46 during the movement, so that the L-shaped column rod 54 drives the scraper rod 55 to scrape foreign matter adhered to the outer wall of the optical lens blank, thereby helping the T-shaped column 46 to firmly fix the optical lens blank in the correct position, thereby avoiding the presence of foreign matter, resulting in a slight displacement of the optical lens blank during the clamping process, affecting the precision processing operation of laser cutting.

This can reduce the energy reflected back to the laser source, thereby reducing the risk of equipment damage. At the same time, the rough surface of the optical lens blank can promote the scattering and absorption of laser energy, and the laser will have more heat exchange with the surface, thereby improving the cutting efficiency. At the same time, the baffle 65 can help shield the area that does not need to be irradiated, and prevent the laser beam from irradiating the part that should not be cut. The baffle 65 can be used as a physical barrier, allowing the laser beam to focus only on a specific cutting area, preventing the laser beam from diffusing and damaging other parts of the optical lens blank.

Through the setting of the above structure, the rotating wheel 69 can rotate under the friction between the rough surface of the optical lens blank and the rotating wheel 69. The staff can determine the part of the optical lens blank in the cutting track of the laser cutting machine body 3 by observing the rotation of the rotating wheel 69. Whether it has been roughened is determined to determine whether to start the laser cutting machine body 3 to perform laser cutting on the optical lens blank.

During the laser cutting process of the optical lens blank, the temperature of the cutting point is extremely high, and the surface of the optical lens blank is easily melted or burned due to heat accumulation. The fan blade 610 drives the surrounding air to flow by rotating, which helps to dissipate heat, reduce the temperature of the cutting area, and reduce the heat-affected area on the lens surface, thereby improving the cutting quality and preventing damage or deformation of the optical lens surface.

[0036] When in use, after the T-shaped column 46 clamps and fixes the optical lens blank, the screw rod 62 is manually rotated, and the screw rod 62 drives the connecting rod 66 to move downward. The connecting rod 66 drives the grinding block 67 to contact the top of the optical lens blank through the fixed tube 64, and the connecting rod 66 will drive the telescopic end of the elastic telescopic rod 61 to stretch. In the process of the optical lens blank driven by the turntable 43 to rotate, the grinding block 67 will roughen the part of the optical lens blank that is on the cutting track of the laser cutting machine body 3. The rough surface of the optical lens blank will scatter the reflected light of the laser beam of the laser cutting machine body 3, instead of reflecting the laser back to the equipment like a smooth mirror surface. This can reduce the energy reflected back to the laser source, thereby reducing the risk of equipment damage. At the same time, the rough surface of the optical lens blank can promote the scattering and absorption of laser energy, and the laser will have more heat exchange with the surface, thereby improving the cutting efficiency. At the same time, the blocking tube 65 can help shield the area that does not need to be irradiated, and prevent the laser beam from irradiating the part that should not be cut. The blocking tube 65 can be used as a physical barrier. , only allowing the laser beam to focus on a specific cutting area, preventing the laser beam from diffusing and damaging other parts of the optical lens blank; when the optical lens blank is in the cutting track of the laser cutting machine body 3 and is roughened, the wheel 69 can rotate under the friction between the rough surface of the optical lens blank and the rotating wheel 69. The staff can determine whether the part of the optical lens blank in the cutting track of the laser cutting machine body 3 has been roughened by observing the rotation of the rotating wheel 69, so as to determine whether to start the laser cutting machine body 3 to perform laser cutting on the optical lens blank. During the rotation of the rotating wheel 69, the rotating shaft of the rotating wheel 69 will drive the fan blade 610 to rotate. During the laser cutting process of the optical lens blank, the temperature of the cutting point is extremely high, and the surface of the optical lens blank is easily melted or burned due to heat accumulation. The fan blade 610 drives the surrounding air to flow by rotating, which helps to dissipate heat, reduce the temperature of the cutting area, and reduce the heat-affected area on the lens surface, thereby improving the cutting quality and preventing damage or deformation of the optical lens surface.
