Description

Technical Field

[0001] This invention relates to the field of lens manufacturing technology, and more specifically, to a lens cutting machine. Background Technology

[0002] With the continuous advancement of technology, lenses, as photosensitive elements, are widely used in fields such as medical care and security monitoring, bringing people many conveniences. Lens assembly usually involves first mounting the lens element on the lens barrel, then mounting the accessories on the lens barrel, and finally applying adhesive to the mounting positions to fix the lens element and accessories on the lens barrel. Due to substandard assembly precision and sealing, some lenses are defective and unusable.

[0003] Discarding defective lenses directly would waste internal lens elements and increase production costs. Because of the adhesive application during lens assembly, it's difficult to manually disassemble the lens and remove the internal lens elements. Manual cutting relies heavily on worker experience, resulting in poor consistency of disassembled parts, low production efficiency, and unreliable product quality. To address this, Chinese Patent Application No. CN202321911078X discloses a cutting device, including a clamping assembly, a driving assembly, a first base, a first guide structure, a cutting assembly, and a second guide structure. The clamping assembly is used to clamp the lens. The driving assembly connects to the clamping assembly and drives the lens to rotate. Both the clamping assembly and the driving assembly are located on the first base. The first base is located on the first guide structure and moves along the guide direction of the first guide structure to move the lens position. The cutting assembly is used to cut the outer wall of the lens. The cutting assembly is located on the second guide structure and moves along the guide direction of the second guide structure to feed towards the outer wall of the lens, thereby completing the cutting of the outer wall of the lens. Chinese patent application CN202121798890.7 discloses a lens disassembly device, including a main body with a worktable. The device further includes a feeding mechanism, a picking mechanism, and a cutting mechanism. The feeding mechanism includes a lens tray, and the picking mechanism includes a drive assembly and a clamping assembly. The clamping assembly is movably connected to the drive assembly. The drive assembly drives the clamping assembly to rotate along its central axis while simultaneously moving axially, causing the lens fixed to the clamping assembly to move synchronously, thus enabling the cutting mechanism to cut the lens housing. However, this solution cannot achieve multi-segment cutting of the lens, and the cutting process causes dust to fly around the room, easily polluting the production of optical components.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The problem solved by this invention is that existing devices cannot effectively control the dust generated during lens cutting, which can easily cause pollution to the production area of ​​optical components; another technical problem solved by this invention is that existing devices cannot perform multi-segment cutting of lenses.

[0006] To address the aforementioned problems, this invention provides a lens cutting machine, comprising a cutting device, a rotating clamping device, and a hopper mounted on a mounting plate. The cutting device is located on one side of the rotating clamping device and is used for cutting lenses. A conveying device is provided between the rotating clamping device and the hopper, and the conveying device is provided with multiple clamping parts for transferring lenses before and after cutting. The lens cutting machine also includes a dust collection assembly, which includes a protective end cap located on the side of the cutting device near the rotating clamping device for collecting dust generated during cutting.

[0007] The lens in the hopper is transferred to the rotary clamping device by the conveying device, and then the lens is cut by the cutting device. At the same time, the dust or solid debris generated is collected by the dust collection component. The dust generated during the entire lens cutting process can be controlled and will not affect the production environment of this optical component.

[0008] Preferably, the protective cover end cap has a notch and a flange on the side near the rotating clamping device, the flange is located above the notch, and air blowing components are respectively provided on both sides of the flange to form a gas seal on both sides of the protective cover end cap.

[0009] This design utilizes high-pressure gas to seal both sides of the protective cover end cap. The high-pressure gas on both sides of the end cap is continuously drawn in by a vacuum cleaner, transporting the cutting powder into the vacuum cleaner and preventing it from escaping. The protective cover end cap has a first connecting hole on the side furthest from the rotating clamping device, which connects to the vacuum cleaner.

[0010] Preferably, the air blowing assembly includes a first air blowing plate and a sealing plate. The sealing plate is fixed to the flange, and the first air blowing plate is located on the side of the sealing plate away from the flange. The first air blowing plate is connected to high-pressure gas, and a portion of the first air blowing plate near the sealing plate is recessed to form a first air outlet channel for blowing air downwards. This arrangement does not interfere with the movement of the rotating clamping device, effectively preventing dust from escaping from both sides of the cutting machine and ensuring stable and reliable operation of the lens cutting machine.

[0011] Preferably, the dust collection assembly further includes a dust collection box located below the rotary clamping device. A second air blowing plate and a sealing plate are disposed on the upper part of the dust collection box. The second air blowing plate is connected to high-pressure gas, and the sealing plate is located above the second air blowing plate. The second air blowing plate forms a first inclined surface on the side near the sealing plate. The first inclined surface is higher on the side near the dust collection box than on the other side. The first inclined surface is partially recessed to form a recessed portion. The recessed portion cooperates with the sealing plate to form a second air outlet channel for blowing air towards the side near the cutting device.

[0012] This design guides the airflow downwards and forwards, creating a gas seal at the top of the dustbin to prevent dust from spreading outwards. The first and second sidewalls each have arc-shaped notches to avoid obstructing the rotating clamping device.

[0013] Preferably, the width of the dust collection box is L1, and the length of the recess is L2, where L2 = (0.9-0.95) * L1, and the angle α between the airflow from the second air outlet channel and the horizontal plane is 10-15°. This arrangement ensures that the generated dust is contained within a small area, effectively preventing dust escape. The distance between the two first air outlet channels is M1, and the width of the dust collection box is M2, where M1 = (0.9-0.95) * M2. This arrangement ensures a wider dust collection box, allowing more gas from the first air outlet channel to enter the dust collection box, resulting in better dust prevention. The length of the recess refers to its length in the width direction of the dust collection box, and the second air blowing plate is positioned higher than the first or second air gripper.

[0014] Preferably, the rotating clamping device includes a first rotating mechanism and a second rotating mechanism arranged opposite to each other. The second rotating mechanism can move closer to or further away from the first rotating mechanism. The first rotating mechanism is equipped with a first pneumatic gripper, and the second rotating mechanism is equipped with a second pneumatic gripper. The second pneumatic gripper is arranged opposite to the first pneumatic gripper and is used to clamp and fix the lens. This arrangement allows the second rotating mechanism to move closer to or separate from the first rotating mechanism. At the same time, the swing stage cylinder can rotate the second pneumatic gripper by 90°, thereby obtaining the lens from the conveying device or transferring the cut material to the conveying device. The second pneumatic gripper cooperates with the first pneumatic gripper to clamp the lens, and the rotation of the clamped lens is achieved by the second rotating R-axis.

[0015] Preferably, the first rotating mechanism includes an R-axis moving plate vertically disposed on the mounting plate, a first rotating R-axis is disposed at one end of the R-axis moving plate, a second rotating R-axis is disposed at one end of the first rotating R-axis, the first rotating R-axis and the second rotating R-axis rotate in a first plane and a second plane respectively, the first plane is disposed perpendicular to the second plane, and a first pneumatic gripper is disposed at the end of the second rotating R-axis.

[0016] This setup allows the lens to be retrieved from the conveying device or the cut material to be transferred to the conveying device via the rotation of the first rotating R-axis. The second rotating R-axis is used to drive the rotation of the first pneumatic gripper to hold and fix the lens, thereby enabling the cutting device to cut the outer periphery of the lens.

[0017] Preferably, the second rotating mechanism includes a driven X-axis, with a vertically positioned swing cylinder mounted on the upper part of the driven X-axis, and a freely rotatable second pneumatic gripper mounted on one side of the swing cylinder. This arrangement is compact and occupies little space.

[0018] Preferably, the conveying device includes a mounting frame mounted on a mounting plate, a conveying X-axis mounted on the mounting frame, the conveying X-axis being located above the rotary clamping device and the hopper, a conveying Z-axis mounted on the conveying X-axis, and a clamping part mounted on the conveying Z-axis.

[0019] This setup allows the clamping unit to move between the rotary clamping device and the hopper via the X-axis, while simultaneously using the Z-axis to move the clamping unit up and down along the Z-axis direction, picking up or placing materials from or into the rotary clamping device or hopper.

[0020] Preferably, the hopper includes a cover fixed to a mounting plate, the cover has an opening on one side, a liftable shelf is provided inside the cover, and the mounting plate is provided with a material picking Y-axis that can extend into the cover to remove the shelf.

[0021] Compared with the prior art, the lens cutting machine of the present invention has the following advantages: 1) By setting up a dust collection component, the dust in the lens cutting process can be effectively controlled, avoiding dust overflow and contamination of the production area, which is crucial for the assembly of the lens, an optical component; 2) By using multiple clamping parts and a rotating clamping device, the lens can be cut into 2-4 segments, which is beneficial for the recycling of multiple lenses in the lens and has high cutting efficiency; 3) The structure is compact and easy to manufacture.

[0043] Due to their crucial role in security, parking management, and intelligent transportation, the demand for lenses is rapidly increasing. Lens failures due to human error and vibrations during assembly are frequent occurrences. For defective lenses that cannot be repaired or downgraded, disassembly is necessary to extract and reuse the elements to minimize unnecessary waste. To achieve higher image quality, multi-element lenses have become mainstream in the high-end market. However, existing lens cutting equipment cannot perform multi-segment cutting, and the dust generated during cutting contaminates the entire optical component manufacturing environment. Therefore, the applicant proposes the following technical solution:

[0044] like Figure 1-11 As shown, a lens cutting machine includes a cutting device 1, a rotating clamping device 3, a conveying device 4, and a hopper 5. The conveying device 4 is disposed between the rotating clamping device 3 and the hopper 5 for transferring materials before and after cutting between the hopper 5 and the rotating clamping device 3. The cutting device 1 is disposed on one side of the rotating clamping device 3 for cutting the lens 9. The lens cutting machine also includes a dust collection assembly 2, which includes a protective cover end cap 21. The protective cover end cap 21 is located on the side of the cutting device 1 near the rotating clamping device 3 for collecting dust generated during cutting.

[0045] The lens 9 in the hopper 5 is transferred to the rotary clamping device 3 by the conveying device 4, and then the lens 9 is cut by the cutting device 1. At the same time, the dust or solid debris generated is collected by the dust collection component 2. The dust generated during the entire lens cutting process can be controlled and will not affect the production environment of the entire lens 9 optical component. The structure is compact and occupies little space.

[0046] As an example of the present invention, the cutting device 1 includes a cutting X-axis 11, a cutting Y-axis 12 is disposed above the cutting X-axis 11, and a cutting motor 13, a transmission structure 14, and a cutting blade 15 are disposed above the cutting Y-axis 12. The cutting blade 15 is disposed close to the rotating clamping device 3 and can move along the plane formed by the X-axis and Y-axis to cut the lens 9. This arrangement can cut different positions of the lens 9 on the rotating clamping device 3 as needed, thereby cutting the lens 9 into 2-4 segments; the structure is simple and easy to manufacture.

[0047] Preferably, the cutting X-axis 11 includes an X-axis motor 111, a coupling 112, and a lead screw 113 connected in sequence. A lead screw nut 114 is provided on the lead screw 113, and a movable plate 115 is fixedly provided on the upper side of the lead screw nut 114 for mounting the cutting Y-axis 12. This arrangement can convert the rotation of the motor into linear motion, which has the advantages of high power transmission efficiency and accurate positioning. Preferably, the cutting Y-axis 12 and the cutting X-axis 11 have the same transmission method, which will not be described in detail here. As an example of the present invention, the transmission structure 14 is a synchronous pulley and gear structure.

[0048] Preferably, the protective cover end cap 21 is disposed around the cutting blade 15. A notch 211 is provided on one side of the protective cover end cap 21 to avoid the rotating clamping device 3. A first connecting hole 213 is provided on the side of the protective cover end cap 21 away from the rotating clamping device 3, and the first connecting hole 213 is connected to a vacuum cleaner (not shown in the figure). After the lens 9 is cut, the generated dust is sucked into the vacuum cleaner, preventing dust from splashing into the external environment and facilitating continuous production.

[0049] Preferably, the protective cover end cap 21 has a flange 212 on the side near the rotating clamping device 3, the flange 212 being located above the notch 211, and air blowing components 22 are respectively provided on both sides of the flange 212 to form a gas seal on both sides of the protective cover end cap 21. This arrangement can use high-pressure gas to seal both sides of the protective cover end cap 21, and the high-pressure gas on both sides of the protective cover end cap 21 is continuously sucked in by the vacuum cleaner, which can transport the cutting powder into the vacuum cleaner and prevent the powder from escaping outward.

[0050] Preferably, the air blowing assembly 22 includes a first air blowing plate 221 and a sealing plate 222. The sealing plate 222 is fixed to the flange 212. The first air blowing plate 221 is located on the side of the sealing plate 222 away from the flange 212. The first air blowing plate 221 is connected to high-pressure gas. The first air blowing plate 221 has a recessed portion on the side near the sealing plate 222 to form a first air outlet channel for downward air outlet to form a gas seal on the side of the protective cover end cap 21. This arrangement does not interfere with the movement of the rotating clamping device 3, effectively preventing dust from escaping from both sides of the cutting machine and ensuring stable and reliable operation of the lens cutting machine.

[0051] The lens cutting machine also includes a frame 6, which includes a base frame 62. An upper frame 61 is mounted on the base frame 62. An mounting plate 611 is provided between the upper frame 61 and the base frame 62. The cutting device 1, the rotating clamping device 3, and the conveying device 4 are all mounted on the mounting plate 611.

[0052] As an example of the present invention, the dust collection assembly 2 further includes a dust collection box 23. The mounting plate 611 is provided with a vertical plate 26, and the dust collection box 23 is disposed on one side of the vertical plate 26. A first sidewall 231 and a second sidewall 232 are respectively disposed on both sides of the dust collection box 23. The first sidewall 231 and the second sidewall 232 form an avoidance notch 233 on the side closest to the cutting device 1. This arrangement provides good dust collection performance without interfering with the cutting device 1.

[0053] Preferably, the upper part of the dust collection box 23 is provided with a second air blowing plate 25 and a sealing plate 24. The second air blowing plate 25 is connected to high-pressure gas, and the sealing plate 24 is located above the second air blowing plate 25. The second air blowing plate 25 forms a first inclined surface on the side near the sealing plate 24. The first inclined surface is higher on the side near the dust collection box 23 than on the other side. The first inclined surface is partially concave downward to form a recessed portion. The recessed portion cooperates with the sealing plate 24 to form a second air outlet channel for blowing air towards the cutting device 1. This arrangement guides the airflow downward and forward, thereby forming a gas seal on the top of the dust collection box 23 to prevent dust from spreading outward. The first sidewall 231 and the second sidewall 232 are respectively provided with arc-shaped notches to avoid the rotating clamping device 3. Preferably, the width of the dust collection box 23 is L1, and the length of the recess is L2, where L2 = (0.9-0.95) * L1. The angle α between the airflow from the second air outlet channel and the horizontal plane is 10-15°. This arrangement ensures that the generated dust is contained within a small area, effectively preventing dust escape. The distance between the two first air outlet channels is M1, and the width of the dust collection box 23 is M2, where M1 = (0.9-0.95) * M2. This arrangement ensures a larger width for the dust collection box 23, allowing more gas from the first air outlet channel to enter the dust collection box 23, resulting in better dust prevention.

[0054] Preferably, a grid 235 is provided inside the dust collection box 23, and the grid 235 is located above the second connecting hole 234. This arrangement can prevent unsecured lenses 9 from falling directly into the second connecting hole 234, ensuring that the entire production process can continue.

[0055] The rotating clamping device 3 includes a first rotating mechanism 31 and a second rotating mechanism 32 arranged opposite to each other. The second rotating mechanism 32 can move closer to or further away from the first rotating mechanism 31. A dust collection box 23 is provided between the first rotating mechanism 31 and the second rotating mechanism 32. A second connecting hole 234 is provided at the bottom of the dust collection box 23, and the second connecting hole 234 is connected to a vacuum cleaner. After the lens 9 is cut, the generated dust falls downward into the dust collection box 23 under the action of gravity and is then sucked into the vacuum cleaner, avoiding dust accumulation at the cutting station and facilitating continuous production.

[0056] like Figure 8As shown, the first rotating mechanism 31 includes an R-axis moving plate 311 vertically mounted on the mounting plate 611. A first rotating R-axis 312 is located at one end of the R-axis moving plate 311, and a second rotating R-axis 313 is located at one end of the first rotating R-axis 312. The first rotating R-axis 312 and the second rotating R-axis 313 rotate within a first plane and a second plane, respectively. The first plane is perpendicular to the second plane. A first pneumatic gripper 314 is located at the end of the second rotating R-axis 313, and the first pneumatic gripper 314 is used to clamp one end of the lens 9. This configuration allows the lens 9 to be retrieved from the conveying device 4 or the cut material to be transferred to the conveying device 4 through the rotation of the first rotating R-axis 312. The second rotating R-axis 313 drives the first pneumatic gripper 314 to clamp and fix the rotation of the lens 9, thereby enabling the cutting device 1 to cut the outer periphery of the lens 9.

[0057] The structures of the first rotating R-axis 312 and the second rotating R-axis 313 may be the same or different. As an example of the present invention, the first rotating R-axis 312 includes a connected servo motor, a hollow rotating platform (100W high-speed bearing type), and a rotating shaft. Its specific structure and assembly relationship are prior art and will not be described in detail here.

[0058] Preferably, the first rotating mechanism 31 further includes a sensing device 315, which is located on the R-axis moving plate 311 and positioned higher than the first rotating R-axis 312. This arrangement enables the detection of the start and stop of the first rotating R-axis 312, facilitating automated production. The structures of the sensing device 315 and the first pneumatic gripper 314 are existing technologies and will not be described in detail here. Preferably, a reinforcing plate 316 is provided on one side of the R-axis moving plate 311, with two reinforcing plates 316 located at both ends of the R-axis moving plate 311. This arrangement improves the mechanical strength of the R-axis moving plate 311 and ensures a stable and reliable connection.

[0059] The maximum distance between the first pneumatic gripper 314 and the notch 211 is X1, and the width of the first air outlet channel is X2, where X2 = 1.2 * X1. This configuration, through the dust collection box 23, the first gas channel, the second gas channel, and the protective cover end cap 21, can form a three-dimensional seal for the cutting area, effectively preventing dust escape.

[0060] like Figure 9As shown, the second rotating mechanism 32 includes a driven X-axis 321. A vertically positioned swing cylinder 322 is mounted on the upper part of the driven X-axis 321. A freely rotatable second gripper 323 is mounted on one side of the swing cylinder 322. The second gripper 323 is positioned opposite to the first gripper 314 and is used to hold and fix the lens 9. This configuration allows the second rotating mechanism 32 to move closer to or separate from the first rotating mechanism 31. Simultaneously, the swing cylinder 322 allows the second gripper 323 to rotate 90°, thereby retrieving the lens 9 from the conveying device 4 or transferring cut materials to the conveying device 4. The second gripper 323 cooperates with the first gripper 314 to clamp the lens 9, and the rotation of the clamped lens 9 is achieved through the second rotating R-axis 313.

[0061] Preferably, the driven X-axis 321 is a lead screw drive, with a sliding block 324 on the lead screw nut and a swing cylinder 322 on the sliding block 324. The structures of the first pneumatic gripper 314 and the second pneumatic gripper 323 may be the same or different, and the specific structures of the swing cylinder 322 and the second pneumatic gripper 323 are existing technologies.

[0062] like Figure 10-11 As shown, the conveying device 4 includes a mounting frame 41 mounted on a mounting plate 611. A conveying X-axis 42 is mounted on the mounting frame 41, located above the rotary clamping device 3 and the hopper 5. A conveying Z-axis 43 is mounted on the conveying X-axis 42, and a clamping part 44 is mounted on the conveying Z-axis 43 for holding the lens 9. This arrangement allows the clamping part 44 to move between the rotary clamping device 3 and the hopper 5 via the conveying X-axis 42, while simultaneously using the conveying Z-axis 43 to move the clamping part 44 up and down along the Z-axis direction, picking up or placing materials from or into the rotary clamping device 3 or the hopper 5.

[0063] As an example of the present invention, the mounting frame 41 includes two connected columns 411 and a top plate 412. A rotating clamping device 3 and a hopper 5 are arranged between the two columns 411. The two ends of the top plate 412 are fixedly connected to the upper ends of the columns 411 respectively, for assembling and transporting the X-axis 42. This arrangement has a simple structure, is compact, and has high space utilization.

[0064] Preferably, the transport X-axis 42 includes a linear motor 421 disposed on one side of the top plate 412, the top plate 412 being placed along the Z-axis direction, and the linear motor 421 having a sliding member 422 disposed on the side away from the top plate 412 for assembling the transport Z-axis 43.

[0065] As an example of the present invention, the conveying Z-axis 43 includes a plate 431 fixedly connected to a sliding member 422. A base plate 432 is provided on the side of the plate 431 away from the sliding member 422. The base plate 432 is provided with a Z-axis motor 433, a synchronous belt 438, and synchronous pulleys 435. There are two synchronous pulleys 435, and a synchronous belt 348 is provided between the synchronous pulleys 435. One of the synchronous pulleys 435 is driven by the Z-axis motor 433 to drive the synchronous belt 438 to reciprocate. The base plate 432 is provided with a sliding assembly 437, and a clamping part 44 is provided on the sliding assembly 437. The clamping part 44 is fixedly assembled with the synchronous belt 438. This arrangement allows the Z-axis motor 433 to drive the clamping part 44 to move up and down along the sliding assembly 437 on the Z-axis via the synchronous belt 438. The structure is simple and easy to manufacture.

[0066] Preferably, the sliding assembly 437 includes a slide rail 4371 disposed on a base plate 432, a slider 4372 disposed on the slide rail 4371, and a clamping part 44 disposed on the slider 4372. This arrangement has a simple structure and provides stable and reliable transmission. As an example of the present invention, a mounting block 436 is disposed on one side of the clamping part 44, and a pressure plate 434 is disposed on the side of the mounting block 436 away from the clamping part 44. The pressure plate 434 cooperates with the mounting block 436 to fix the synchronous pulley 435.

[0067] As an example of the present invention, the clamping part 44 includes a gripper connecting plate 441 disposed on the slider 4372, a pneumatic gripper cylinder 442 disposed on the gripper connecting plate 441, pneumatic gripper mounting blocks 443 disposed on both sides of the pneumatic gripper cylinder 442, and a third pneumatic gripper 444 disposed on the pneumatic gripper mounting blocks 443 for gripping the lens 9. Preferably, there are two base plates 432, and two clamping parts 44 are disposed on the base plates 432 respectively. This arrangement results in a total of four clamping parts 44 on the conveying device 4, which can transfer the lens 9 into the hopper 5 in one go after it is cut into two, three, or four pieces, thereby improving production efficiency.

[0068] As an example of the present invention, the hopper 5 includes a cover 53 fixed on a mounting plate 611. One side of the cover 53 is open, and a liftable shelf 52 is disposed inside the cover 53. The mounting plate 611 is provided with a material-picking Y-axis 51, which can extend into the cover 53 to remove the shelf 52. The specific structure of the hopper 5 is prior art and will not be described in detail here.

[0069] Preferably, a downwardly inclined conveying trough 8 is provided between the material picking Y-axis 51 and the rotating clamping device 3, and a material box 7 is provided at the end of the conveying trough 8 for collecting waste material. This arrangement allows the conveying device 4 to transfer the cut material, and after moving it above the conveying trough 8, the clamping part 44 is opened to discard the waste material into the conveying trough 8, and finally it slides downward into the material box 7.

[0070] This invention also provides a control method for a lens cutting machine, comprising:

[0071] S1. Raise the shelf 52 in the hopper 5 to the specified height, and insert the material picking Y-axis 51 into the cover 53 to remove the shelf 52.

[0072] S2. The conveying device 4 moves downward by conveying the Z-axis 43 and uses the clamping part 44 to fix the lens 9 on the shelf 52 and transfer it to the first rotating mechanism 31.

[0073] S3. After the first rotating mechanism 31 rotates 90°, the second rotating mechanism 32 moves to one side of the first rotating mechanism 31 and supports the other side of the lens 9.

[0074] S4. The lens 9 is driven to rotate by the first rotating mechanism 31, and the cutting device 1 moves to the designated position to cut the lens 9. The dust collection assembly 2 performs gas sealing on the cut part.

[0075] S5. After cutting, the second rotating mechanism 32 moves away from the first rotating mechanism 31. The first rotating mechanism 31 and the second rotating mechanism 32 rotate 90° respectively to transfer the cut material to the handling device 4 and transport it to the silo 5.

[0076] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
