Description

Technical Field

[0001] This invention relates to the field of marking technology for eyeglass lenses, and more specifically to laser marking equipment for eyeglass lenses. Background Technology

[0002] Laser marking uses a high-energy laser beam to irradiate the surface of eyeglass lenses, causing the material to vaporize or change color instantly, forming micron-level fine marks. This non-contact process does not damage the lenses. The printed marks are usually very small and located at the edges, not affecting the wearer's vision. These marks are as follows: Anti-counterfeiting verification: Branded eyeglass lenses will be engraved with a logo or serial number to help consumers distinguish between genuine and counterfeit products. Authentic products have clear and precise markings.

[0003] Record parameters: Special lenses such as progressive lenses will have parameters such as refractive index, ADD value, and channel length engraved on them.

[0004] Production tracking: Used to identify batches and production lines, facilitating quality control and product traceability.

[0005] Positioning aid: Serves as a positioning reference during processing to ensure accurate cutting and assembly. CN207723699U discloses a laser marking device for spectacle lenses. This device features a lens holder with a double-lens clamping structure, capable of holding two lenses simultaneously. Combined with a cylinder structure, the lens holder can be automatically moved during marking, achieving automated marking. Only after both lenses are marked does manual replacement of the next pair become necessary, resulting in higher operational efficiency and reducing the risk of confusion. The slider employs a spring structure, making lens installation and removal more convenient.

[0006] The above-mentioned laser marking machine has the following problems: First, manual loading and unloading is required, which is inefficient. Also, because the distance between different specifications of eyeglass lenses and the marking machine is not the same, while the distance between the aforementioned laser marking equipment for eyeglass lenses and the lens fixing plate is fixed, it can only be used for marking one specification of eyeglass lenses.

[0007] Secondly, before marking, the unnecessary parts of the eyeglass lenses have been cut off by machining. Water is required during machining. The core functions of water are cooling and crack prevention, washing away debris, lubrication and friction reduction, and ensuring the dimensional accuracy and surface smoothness of the eyeglass lenses. Since the next process after machining is laser marking, water is often left on the surface of the eyeglass lenses after machining. When loading manually, eyeglass lenses with water residue on the surface are usually placed directly on the lens chuck. Since the lens chuck is driven by a gripper cylinder, the water on the surface of the eyeglass lenses will flow onto the gripper cylinder, which will cause damage to the gripper cylinder after long-term use. Summary of the Invention

[0008] This invention provides a laser marking device for eyeglass lenses. This invention not only has high production efficiency, but is also applicable to marking eyeglass lenses of various specifications.

[0009] The technical solutions to the above technical problems are as follows: The spectacle lens laser marking equipment includes a first bracket, a laser marking machine, a controller, and a lens holder for supporting spectacle lenses. The laser marking machine is fixed to the first bracket. It also includes a conveying mechanism connected to the controller, which is located on one side of the laser marking machine. A tooling box for carrying lens holders; a conveying mechanism works with the tooling box to move the tooling box. The component under test is mounted on the tooling box. The first sensor is used to detect the component under test and is connected to the controller. The first clutch assembly is connected to the controller. A rotary lifting mechanism, which works in conjunction with a laser marking machine; Multiple clamping components for holding lens holders are mounted on a rotating and lifting mechanism; A second sensor that detects the lens holder and is connected to the controller is mounted on the clamping assembly; An extraction and release mechanism that allows the lens holder to switch positions between the tooling box and the clamping assembly.

[0010] The present invention has the following advantages: 1. This invention, through the cooperation of the first sensor, the conveying mechanism, and the extraction and release mechanism, automatically switches the eyeglass lenses between the tooling box and the clamping mechanism, so that the loading and unloading of marking do not require manual intervention, which helps to improve efficiency.

[0011] 2. The present invention uses a rotary lifting mechanism in conjunction with two clamping components, so that one clamping component is positioned below the laser marking, while the other clamping component receives the material. After marking is completed, the two clamping components are immediately interchanged by the rotary lifting mechanism, which helps to improve efficiency.

[0012] 3. This invention uses the lifting function of the rotating lifting mechanism to adjust the distance between the spectacle lens and the laser marking equipment, so as to meet the needs of marking spectacle lenses of different specifications.

[0013] 4. After the lens is loaded onto the clamping assembly, even if water falls from the surface of the lens, the water-blocking structure in this invention prevents water from acting on the clamping assembly, thus protecting the cylinder in the clamping assembly. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 8As shown, the spectacle lens laser marking equipment of the present invention includes a first support 1, a laser marking machine 2, a controller 3, a lens holder 4, a conveying mechanism 5, a tooling box 6, a component to be tested 7, a first sensor 8, a first clutch assembly 9, a rotary lifting mechanism B, a clamping assembly C, a second sensor 10, and an extraction and release mechanism D. The following is a detailed description of each part and the relationship between them.

[0025] The first support 1 includes a worktable 1a and a support frame 1b, with the support frame 1b fixed to the worktable 1a. The laser marking machine 2 is fixed to the support frame 1b in the first support 1. The laser marking machine 2 is electrically connected to a controller 3, which sends marking control signals to the laser marking machine 2. An industrial computer is preferred as the controller 3.

[0026] The lens holder 4 is used to support the spectacle lens A. The lens holder 4 includes a tray 4a and a base 4b detected by the second sensor 10. One end of the tray 4a has a mounting groove 4c for interference fit with the spectacle lens A. The groove 4a has a positioning block 4d for circumferential positioning of the spectacle lens A. The circumferential surface of the spectacle lens A has multiple notches. After the positioning block 4d engages with the notches, it forms a circumferential positioning of the spectacle lens A. The other end of the tray 4a is fixed to one end of the base 4b. The other end of the base 4b has a groove 4e for engaging with the clamping assembly C to restrict the rotation of the lens holder 4.

[0027] The conveying mechanism 5 is connected to the controller 3 and is located on one side of the laser marking machine 2. The conveying mechanism 5 is arranged laterally along the laser marking machine 2. In this embodiment, the conveying mechanism 5 includes a second support 5a, a flexible transmission mechanism 5b, a first motor (not shown in the figure), and a third support 5c. The flexible transmission mechanism 5b is mounted on the second support 5a, and the first motor is connected to the flexible transmission mechanism 5b. The flexible transmission mechanism 5b is either a belt drive mechanism or a sprocket and chain drive mechanism. In this embodiment, the flexible transmission mechanism 5b preferably uses a belt drive mechanism, and the first motor preferably uses a motor with a reducer. The third support 5c is fixed to the second support 5a. The first sensor 8 and the first clutch assembly 9 are located below the tooling box 6 and fixed to the third support 5c. The first sensor 8 is used to detect the measured component 7 and is connected to the controller 3. The first sensor 8 preferably uses an inductive sensor.

[0028] The first clutch assembly 9 is connected to the controller 3. The first clutch assembly 9 includes a first linear actuator 9a and a first stop block 9b. The power output end of the first linear actuator 9a is fixed to the first stop block 9b. The first linear actuator 9a can be a cylinder, an electric lifting screw, etc. In this embodiment, the first linear actuator 9a is preferably a cylinder. The first linear actuator 9a is fixed to the third bracket 5c.

[0029] The tooling box 6 is used to carry the lens holder 4. The conveying mechanism 5 cooperates with the tooling box 6 to move the tooling box 6. The tooling box 6 includes a box body 6a and a positioning seat 6b for positioning the lens holder 4. The box body 6a is provided with a partition 6c that divides the interior of the tooling box 6 into multiple receiving cavities. The positioning seat 6b is located in the receiving cavity. The positioning seat 6b is provided with a recess. A rod-shaped component is fixed in the recess. When the lens holder 4 is released into the recess on the positioning seat 6b by the extraction and release mechanism D, the groove 4e at the bottom of the lens holder 4 engages with the rod-shaped component, thereby restricting the rotation of the lens holder 4.

[0030] The outer surface of the housing 6a is provided with a connecting part 6d for engaging with the first clutch assembly 9. The component under test 7 is installed at the bottom of the tooling box 6. The component under test 7 is preferably made of metal sheet. When the first sensor 8 detects the component under test 7 on the tooling box 6, the first sensor 8 feeds back the detection information to the controller 3. The controller 3 sends a control command to the first clutch assembly 9. The first linear actuator 9a in the first clutch assembly 9 drives the first stop 9b to rise. The first stop 9b engages with the connecting part 6d, and the connecting part 6d is blocked, so that the tooling box 6 cannot move with the belt in the belt drive mechanism.

[0031] The rotary lifting mechanism B works in conjunction with the laser marking machine 2. Since the spectacle lens A needs to be positioned directly below the laser marking machine 2 during marking, and to improve feeding and marking efficiency, multiple clamping components C are used. For example, in this embodiment, two clamping components C are installed on the rotary lifting mechanism B. The clamping component C located directly below the laser marking machine 2 works with the laser marking machine 2 to mark the spectacle lens, while the other clamping component C is in the feeding state of receiving the lens holder 4. When the spectacle lens A on one clamping component C is marked and the lens holder 4 on the other clamping component C is fed, the controller 3 controls the rotary lifting mechanism B to work. The lifting mechanism B drives the two clamping components C to rotate 180°, so that the two clamping components C interchange positions. Because different lenses A have different parameters, the parameters printed on the lenses by the laser marking machine 2 are also different. The distance between different lenses A and the laser marking machine 2 is different. The distance between the lens A and the laser marking machine 2 is adjusted by rotating and lifting mechanism B to drive clamping component C to rise or fall.

[0032] The rotary lifting mechanism B includes a second linear actuator 11, a fourth bracket 12, a rotary actuator 13, and a turntable 14. The fourth bracket 12 is fixed to the power output section of the second linear actuator 11, the rotary actuator 13 is fixed to the fourth bracket 12, and the turntable 14 is fixed to the power output section of the rotary actuator 13. The second linear actuator 11 preferably uses an electric linear module. The second linear actuator 11 is preferably fixed to the first bracket 1. Preferably, a first through hole is provided on the worktable 1a, and the second linear actuator 11 mates with the first through hole. The second linear actuator 11 is fixed to the support frame 1b.

[0033] The second sensor 10 is connected to the controller 3. The second sensor 10 is positioned on the lens holder 4 and is mounted on the clamping assembly C. The clamping assembly C is used to clamp the lens holder 4 and is mounted on the rotary lifting mechanism B. The clamping assembly C includes a support sleeve 15, a gripper assembly 16, and a positioning rod 17 that engages with the lens holder 4 to perform circumferential positioning of the lens holder 4. One end of the support sleeve 15 is connected to the rotary lifting mechanism B. The second sensor 10 is fixed to the support sleeve 15, with one end of the second sensor 10 located inside the support sleeve 15. The other end of the support sleeve 15 is for the lens holder 4 to be inserted. The gripper assembly 16 is located inside the support sleeve 15 and is fixed to the rotary lifting mechanism B. The positioning rod 17 is fixed to the support sleeve 15.

[0034] The clamping assembly C also includes a baffle plate 18. The gripper assembly 16 includes a cylinder assembly 16a and a plurality of grippers 16b. The grippers 16b are fixed to the power output part of the cylinder assembly 16a. The baffle plate 18 is provided with a plurality of guide plates 19 at intervals along the circumference. The surface of the baffle plate 18 has a plurality of flow-guiding slopes 18a. The surface of the guide plate 19 is an arc-shaped concave surface 19a. Each flow-guiding slope 18a is combined with an arc-shaped concave surface 19a. The end of the guide plate 19 is located outside the circumference of the cylinder assembly 16a. A clearance opening 20 is formed between two adjacent guide plates 19. The clearance opening 20 cooperates with the power output part of the cylinder assembly 16a or the grippers 16b. When liquid falls from lens A onto cylinder assembly 16a, the liquid falls directly onto baffle 18 due to the presence of baffle 18. Under the guiding action of the flow-guiding inclined surface 18a and the arc-shaped concave surface 19a, the liquid is discharged from the end of the guide plate 19, thus preventing the liquid on lens A from falling onto cylinder assembly 16a and providing beneficial protection for cylinder assembly 16a.

[0035] The extraction and release mechanism D allows the lens holder 4 to switch positions between the tooling box 6 and the clamping assembly. The extraction and release mechanism D includes a fifth support 20, a third linear actuator 21 arranged longitudinally along the laser marking machine 2, a fourth linear actuator 22 arranged transversely along the laser marking machine 2, a fifth linear actuator 23 arranged vertically along the laser marking machine 2, and a suction cup assembly 24. The third linear actuator 21 is fixed to the fifth support 20, the fourth linear actuator 22 is fixed to the power output of the third linear actuator 21, the fifth linear actuator 23 is fixed to the power output of the fourth linear actuator 22, and the suction cup assembly 24 is fixed to the power output of the fifth linear actuator 23. The suction cup assembly 24 engages with the spectacle lens A, applying negative pressure to the spectacle lens A. Since the spectacle lens A is fixed to the lens holder 4, once the spectacle lens A is firmly attracted by the suction cup assembly 24, the extraction and release mechanism D can move the spectacle lens A and the lens holder 4 along with it.

[0036] The third linear actuator 21 and the fourth linear actuator 22 preferably use electric linear modules, while the fifth linear actuator 23 preferably uses a cylinder. The structure of the suction cup assembly 24 is existing technology and will not be described in detail here. The third linear actuator 21, the fourth linear actuator 22, the fifth linear actuator 23, and the suction cup assembly 24 are all electrically connected to the controller 3, and their operating states are controlled by the controller 3.

[0037] The laser marking equipment for eyeglass lenses of the present invention also includes a palletizing lifting driver 25 and a clamping mechanism 26. The lifting driver 25 is used to support the palletizing tooling box 6. The palletizing lifting driver 25 cooperates with the conveying mechanism 5. The palletizing lifting driver 25 includes a sixth linear driver and a tray. The sixth linear driver is fixed to the first bracket 1. The sixth linear driver is fixed along the power output end of the laser marking machine 2. The sixth linear driver is preferably a cylinder. The tray is fixed to the power output end of the sixth linear driver.

[0038] The clamping mechanism 26, in conjunction with the lifting driver 25, releases the palletized tooling boxes 6 one by one onto the conveying mechanism 5. The clamping mechanism 26 is arranged on both sides of the conveying mechanism 5. There are two clamping mechanisms 26 arranged symmetrically. The clamping mechanism 26 consists of a sixth bracket, a seventh linear driver, and a clamping block. The sixth bracket is fixed to the worktable 1a. The seventh linear driver is preferably a cylinder. The seventh linear driver is fixed to the sixth bracket, and the clamping block is fixed to the power output end of the seventh linear driver.

[0039] First, place the stacked tooling boxes 6 on the stacking lifting drive 25, with the bottom tooling box 6 positioned above the belt in the belt drive mechanism. When it is necessary to release the bottom tooling box 6 onto the belt, the clamping mechanism 26 clamps the tooling box 6 on top of the bottom tooling box, switching the stacking tooling box to be lifted by the clamping mechanism 26. At this time, the lifting drive 25 operates and drives the bottom tooling box 6 to descend, causing the tooling box 6 to fall onto the belt. After the tooling box 6 moves with the belt, the lifting drive 25 rises to lift the stacking tooling box. Repeating the above process, the stacking tooling boxes can be released onto the belt sequentially.

[0040] The laser marking equipment for spectacle lenses of the present invention also includes a purging mechanism for purging liquid from the surface of spectacle lens A. The purging mechanism is located on one side of the conveying mechanism 5. The purging assembly includes a sixth bracket 27, an air supply assembly 28, and an air nozzle 29. The sixth bracket 27 is fixed to the support frame 1b in the first bracket 1, the air supply assembly 28 is fixed to the sixth bracket 27, and the air nozzle 29 is connected to the air supply assembly 28 and is located above the conveying mechanism 5. By purging the liquid from the surface of spectacle lens A with the gas generated by the purging mechanism, the residual liquid on spectacle lens A is reduced or even eliminated. This reduces the probability of liquid falling onto the gripper assembly 16 when the spectacle lens is subsequently transferred to the clamping mechanism C, thus providing beneficial protection for the gripper assembly 16.

[0041] The spectacle lens laser marking equipment of the present invention marks spectacle lens A through the following process: S1, place the lens holder 4 carrying the eyeglass lens A into the tooling box 6, place the tooling box 6 on the conveying mechanism 5, and after the conveying mechanism 5 starts working, it drives the tooling box 6 to move.

[0042] S2, when the tooling box 6 moves below the extraction and release mechanism D and the first sensor 8 detects the measured component 7, the first sensor 8 feeds back the signal that the tooling box 6 is in position to the controller 3. The controller 3 sends a control signal to make the first clutch assembly 9 work. After the first clutch assembly 9 engages with the tooling box 6, the tooling box 6 stops moving.

[0043] S3, the controller 3 controls the extraction and release mechanism D to extract the lens holder 4 and the unmarked eyeglass lens A from the tooling box 6 and move them above the clamping assembly C. The controller 3 controls the extraction and release mechanism D to release the lens holder 4 onto the clamping assembly C, which is in an idle state. After the second sensor 10 detects the lens holder 4, the controller 3 controls the clamping assembly C to clamp the lens holder 4. S4, the controller 3 controls the rotating lifting mechanism B to drive the clamping assembly C to rotate, so that the lens holder 4 located below the extraction and release mechanism D and the unmarked eyeglass lens A on it are moved to the bottom of the laser marking machine 2, and the lens holder 4 located below the laser marking machine 2 and the marked eyeglass lens A on it are moved to the bottom of the extraction and release mechanism D.

[0044] S5, controller 3 controls laser marking machine 2 to mark the eyeglass lens A located below it, controller 3 controls clamping mechanism C located below extraction and release mechanism D to release clamping of lens holder 4, controller 3 controls extraction and release mechanism D to extract and move the lens holder 4 located below extraction and release mechanism D and release it into tooling box 6. S6, controller 3 controls the first clutch assembly 9 to reset, conveying mechanism 5 drives tooling box 6 forward one station, and then repeats S2 to S5.
