Description

Technical Field

[0001] This utility model relates to the technical field of glass lens processing equipment, and in particular to a fully automatic glass lens cutting machine. Background Technology

[0002] Glass lenses are made primarily of optical glass, a material known for its excellent optical properties and stability. Glass lenses exhibit superior light transmittance and stable mechanical and chemical properties; compared to other materials, they are less prone to scratches and possess excellent scratch resistance; their outstanding optical performance, with a high refractive index, ensures accurate light transmission and high-quality imaging.

[0003] Cutting glass lenses is a process requiring high precision and meticulous operation to ensure smooth edges, accurate dimensions, and no impact on optical performance. Common cutting methods include CNC cutting, internal circular cutting, and manual cutting. CNC cutting is a highly automated method that uses a pre-programmed control system to precisely cut the lens. This method is suitable for lenses of various shapes and sizes, and is particularly suitable for high-volume, high-precision production. Internal circular cutting is another common lens cutting method, using an internal circular blade to rotate and cut the lens. This method requires adjusting the air pressure or cutting parameters according to the lens's thickness and material to ensure optimal cutting results.

[0004] Based on this, Chinese patent CN219363503U discloses a glass lens cutting device, which includes a main cutting device. A cutting chamber is provided on the upper side of the main cutting device, and a protective mechanism is installed at the bottom of the cutting chamber. The protective mechanism includes a lens holder fixedly mounted at the bottom of the cutting chamber, a protective cover on the outer side of the lens holder, a cover plate movably connected to the upper interior of the protective cover, a cutting head fixedly connected to the lower end of the cover plate, and two sets of circular tubes fixedly connected to the lower end of the cover plate. Limiting rods are fixedly connected to the inner wall of the protective cover near both sides, and springs are fixedly connected between the limiting rods and the upper inner wall of the circular tubes. This glass lens cutting device, by using a cylinder to push the cover plate and cutting head downwards, causes the protective cover to cover the outside of the lens holder, preventing strong light sources from irritating the eyes of workers.

[0005] However, the aforementioned cutting equipment still suffers from insufficient cutting precision. Specifically, the glass lens cutting equipment requires placing the lens on the cutting device and cutting it according to a preset program or operating procedure. During the cutting process, the cutting tool needs to be kept stable and the force applied evenly to ensure the accuracy of the cutting line and the integrity of the lens. However, the cutting head, when cutting the glass lens, can cause chipping and irregular cutting edges on the outer edge of the glass lens, thus affecting the dimensional accuracy of the finished glass lens. To make the edge of the lens smooth, further grinding and polishing of the cut edge is required, which affects the efficiency of batch operations. Utility Model Content

[0028] Please refer to the following: Figures 1 to 4 This utility model discloses a fully automatic glass lens cutting machine, comprising: a base frame 1, a longitudinal drive mechanism 2, a rotary drive mechanism 3, a suction cup support frame 4, a gantry frame 5, a transverse drive mechanism 6, a laser cutting blade assembly 7, and a vision positioning structure 8; the longitudinal drive mechanism 2 is mounted on the base frame 1, the rotary drive mechanism 3 is mounted on the longitudinal drive mechanism 2, and the longitudinal drive mechanism 2 and the rotary drive mechanism 3 are drivenly connected; the suction cup support frame 4 is mounted on the rotary drive mechanism 3, and the rotary drive mechanism 3 is drivenly connected to the suction cup support frame 4; the gantry frame 5 is straddling the suction cup support frame 4, the transverse drive mechanism 6 is mounted on the gantry frame 5, the laser cutting blade assembly 7 is mounted on the side of the transverse drive mechanism 6, the vision positioning structure 8 is adjacent to the laser cutting blade assembly 7, and the transverse drive mechanism 6 is drivenly connected to both the laser cutting blade assembly 7 and the vision positioning structure 8.

[0029] Specifically, when the fully automatic glass lens cutting machine of this invention is in operation, an external transfer device places the glass raw material onto the suction cup support frame 4 to adsorb and limit the glass raw material. Next, the longitudinal drive mechanism 2 drives the rotary drive mechanism 3 to move the suction cup support frame 4 longitudinally to a preset position; the transverse drive mechanism 6 drives the laser cutting blade assembly 7 and the vision positioning structure 8 to move laterally to a preset position. Subsequently, the vision positioning structure 8 communicates with external computer or other equipment to correct the actual cutting position of the laser cutting blade assembly 7; simultaneously, the laser cutting blade assembly 7 emits a laser beam to cut the glass raw material. During cutting, the longitudinal drive mechanism 2, the transverse drive mechanism 6, and the rotary drive mechanism 3 can cooperate to change the position of the glass raw material so that the laser cutting blade assembly 7 can cut the glass raw material along a preset trajectory. This invention relates to a fully automatic glass lens cutting machine. The laser cutting blade group 7 uses a high-energy laser beam to rapidly scan the glass raw material, creating a high-temperature melting zone and generating cracks, thereby cutting the lens. This method is suitable for cutting lenses of various complex shapes and requiring high precision. The edges of the glass cut by this method are smoother and flatter than those cut by ordinary blades, thus improving the precision of glass lens cutting.

[0030] Furthermore, the longitudinal drive mechanism 2 includes a longitudinal support frame 201, a longitudinal drive motor 202, a longitudinal drive screw 203, a longitudinal drive nut slider 204, and a longitudinal moving platform 205; the longitudinal drive motor 202 is disposed at one end of the longitudinal support frame 201, the longitudinal drive screw 203 is movably disposed within the longitudinal support frame 201, and the longitudinal drive motor 202 is drivenly connected to the longitudinal drive screw 203; two longitudinal drive nut sliders 204 are movably connected adjacently to the longitudinal drive screw 203, the longitudinal moving platform 205 is connected to the two longitudinal drive nut sliders 204, and the rotary drive mechanism 3 is disposed on the longitudinal moving platform 205. Specifically, after the longitudinal drive motor 202 is energized, it can drive the longitudinal drive screw 203 to rotate in the forward or reverse direction, thereby enabling the drive screw nut slider 204 to reciprocate along the longitudinal drive screw 203; thereby driving the longitudinal moving platform 205 to reciprocate along the longitudinal direction; and causing the rotary drive mechanism 3 to follow it and reciprocate along the longitudinal direction.

[0031] Furthermore, the rotary drive mechanism 3 includes a rotary motor 301 and a turntable structure 302. The rotary motor 301 is mounted on the longitudinal moving platform 205 and is drivenly connected to the turntable structure 302. The suction cup support platform 4 is mounted on the turntable structure 302. Specifically, after the rotary motor 301 is started, it can drive the turntable structure 302 to rotate, thereby driving the suction cup support platform 4 to rotate, so that the glass material that is limited and connected to the suction cup support platform 4 can be driven to rotate to a preset angle.

[0032] Furthermore, the suction cup support frame 4 includes a support frame 401 and several suction cup structures 402; the support frame 401 is disposed on the turntable structure 302, and the several suction cup structures 402 are evenly distributed on the support frame 401. Specifically, the support frame 401 can be linked with the turntable structure 302, so that when the external transfer mechanism places the glass raw material to be cut onto each suction cup structure 402, the suction cup structure 402 can, under the drive of an external air source, clamp and limit the glass raw material to facilitate subsequent cutting processing.

[0033] Furthermore, the transverse drive mechanism 6 is disposed on the side of the gantry frame 5. The transverse drive mechanism 6 includes a transverse support frame 601, a transverse drive motor 602, a transverse drive lead screw 603, a transverse drive lead screw nut slider 604, and a transverse moving connecting frame 605. The transverse drive motor 602 is disposed at one end of the transverse support frame 601, and the transverse drive lead screw 603 is movably disposed within the transverse support frame 601. The transverse drive motor 602 is drivenly connected to the transverse drive lead screw 603. The transverse drive lead screw nut slider 604 is movably connected to the transverse drive lead screw 603. The transverse moving connecting frame 605 is connected to the side of the transverse drive lead screw nut slider 604. The laser cutting blade assembly 7 and the visual positioning structure 8 are both disposed on the side of the transverse moving connecting frame 605. Specifically, after the transverse drive motor 602 is energized, it can drive the transverse drive screw 603 to rotate in the forward or reverse direction, thereby enabling the drive screw nut slider 604 to reciprocate along the transverse drive screw 603; thereby driving the transverse moving connecting frame 605 to reciprocate in the transverse direction; and enabling the laser cutting blade assembly 7 and the vision positioning structure to follow it and reciprocate in the transverse direction.

[0034] Specifically, the laser cutting blade assembly 7 emits a high-energy laser beam after activation to cut the glass raw material. The visual positioning structure 8 includes a CCD camera module 801 and a supplementary lighting structure 802. The CCD camera module 801 is located adjacent to the laser cutting blade assembly 7 and connected to an external computer, enabling real-time visual image connection.

[0035] In summary, the fully automatic glass lens cutting machine of this utility model is provided with a base frame 1, a longitudinal drive mechanism 2, a rotary drive mechanism 3, a suction cup support frame 4, a gantry frame 5, a transverse drive mechanism 6, a laser cutting blade assembly 7, and a vision positioning structure 8. The longitudinal drive mechanism 2 is arranged on the base frame 1, and the rotary drive mechanism 3 is arranged on the longitudinal drive mechanism 2, and the longitudinal drive mechanism 2 and the rotary drive mechanism 3 are drivenly connected. The suction cup support frame 4 is arranged on the rotary drive mechanism 3, and the rotary drive mechanism 3 is drivenly connected to the suction cup support frame 4. The gantry frame 5 is straddling the suction cup support frame 4, the transverse drive mechanism 6 is arranged on the gantry frame 5, the laser cutting blade assembly 7 is arranged on the side of the transverse drive mechanism 6, the vision positioning structure 8 is arranged adjacent to the laser cutting blade assembly 7, and the transverse drive mechanism 6 is drivenly connected to both the laser cutting blade assembly 7 and the vision positioning structure 8.
