Description

Technical Field

[0001] The present invention relates to the technical field of optical lens processing, and in particular to laser processing equipment for optical lenses. Background Art

[0002] Optical lenses are essential components in machine vision systems, directly impacting image quality and influencing algorithm implementation and effectiveness. Optical lenses are equivalent to the human eye in machine vision systems, focusing the target's optical image onto the photosensitive array of the image sensor (camera). Optical lenses are primarily used in traditional optical components, such as eyeglass lenses, camera lenses, and mobile phone lenses. Furthermore, optical lenses can also be used in optical components that are difficult to manufacture using conventional optical glass, such as Fresnel lenses and aspherical lenses.

[0003] At present, in the processing of optical lenses, laser marking machines are needed to mark them for reasons such as the uniqueness of optical lens identification, quality traceability requirements, process optimization requirements, anti-counterfeiting and brand protection. However, laser marking machines will generate high-energy laser beams during the marking process of optical lenses. Since there is no better protection mechanism, if the laser beam directly irradiates the operator or the surrounding environment, it will cause potential harm to the operator and the environment. For example, the laser beam may burn the operator's skin and cause irreversible damage to the eyes; if the laser beam accidentally irradiates the surrounding flammable and explosive items, it may also cause safety accidents. Although there are some protective devices for laser marking machines on the market, they generally have problems such as poor sealing protection effect, complex structure, and inconvenience in use. Therefore, it is urgent to design a laser processing equipment for optical lenses to solve the above problems. Summary of the Invention

[0016] This type of laser processing equipment for optical lenses forms a wastewater recycling system through the water storage chamber, inlet and outlet water pipes, water pump, suction pipe, and filter cover of the cleaning component, so that water resources can be reused and waste can be reduced. Suction is generated by the dust exhaust component, so that dust enters the dust collection box through the U-shaped suction pipe, the first connecting pipe, the connecting air duct, and the second connecting pipe. The detachable filter bag in the dust collection box further filters the dust. The filter screen at the exhaust port prevents dust from leaking out, effectively avoiding dust pollution of the environment, and ensuring the stable operation of the equipment and the health of the operators. This optical lens laser processing equipment adopts a funnel-shaped design at the bottom of the shielding cover, and fits tightly with the optical lens through a second sealing gasket to form a closed-loop sealed space. This structure has an excellent restraining effect on the laser beam. On the one hand, it prevents the laser beam from accidentally leaking and directly hitting the operator, avoiding irreversible burns to human skin and eyes and even safety accidents such as fire. On the other hand, the funnel-shaped shielding cover can guide the laser beam vertically downward to act on the lens surface, reducing the possibility of laser escape, so that the laser beam is firmly confined to the processing area, providing reliable safety protection for the production environment.

[0024] In summary, the working principle of the present invention is as follows: when in use, the control system controls the drive motor 202 in the conveying mechanism 2 to operate, driving the transmission roller 205 to rotate, driving the input belt 203 and the output belt 204 to operate, thereby smoothly conveying the optical lens from the feed end of the equipment to the rotating table 4, and also outputting it from the rotating table 4. When the lens is conveyed into the advancing groove 7, the lens will squeeze the positioning wheel 1803, causing the movable plate 1801 to rotate around the hinge point, and the V-shaped elastic plate 1802 will undergo elastic deformation to generate elastic force, pushing the positioning wheel 1803 to closely fit the edge of the lens, accurately positioning the lens from both sides, and ensuring that the lens is fixed in position during subsequent processing; Next, when the stepper motor 16 receives the command from the control system, it precisely controls the rotation angle and speed of the rotating shaft 15, thereby driving the rotating table 4 to rotate intermittently. When the positioned optical lens rotates with the rotating table 4 to the bottom of the cleaning assembly 8, the water pump 803 in the cleaning assembly 8 draws water from the water storage chamber 809 and sprays it onto the lens surface at a certain pressure through the drainage pipe 802 and the nozzle 811, thereby washing away dust, oil and other impurities on the lens. The cleaned waste water flows back to the water storage chamber 809 through the support mesh plate 812 and the water conduit 806 in the connecting groove on the bottom side of the fixed frame 3, thus realizing the recycling of water resources. After cleaning, the lens continues to rotate with the rotating table 4 to the bottom of the drying assembly 9. When the lens enters the drying station, the heater 902 is powered on, converting electrical energy into heat energy, and heating and drying the lens through the heating tube to remove the remaining water stains on the lens surface, preparing for subsequent laser processing; The dried lens rotates to the laser processing assembly 10 station, and the infrared sensor 17 in the groove on one side of the inner wall of the fixed frame 3 monitors the lens position in real time. When the lens reaches the laser processing station, the infrared sensor 17 detects the lens and sends a signal to the control system. The control system then controls the forward and reverse motor 1101 in the top frame 5 to start, and the forward and reverse motor 1101 drives the threaded column 1102 to rotate. The door frame 1103 screwed on the threaded column 1102 moves up and down along the slide rail 1104 on the inner wall of the top frame 5 while rotating, and the bottom end of the door frame 1103 is connected to the top of the shielding cover 1002. The laser emitting head 1003 is fixedly connected to the lens, thereby adjusting the height of the laser emitting head 1003 to maintain a suitable processing distance with the lens. When the laser emitting head 1003 is adjusted into place, the laser marking machine 6 transmits energy to the laser emitting head 1003, causing it to emit a high-energy laser beam to perform marking work. The funnel-shaped design at the bottom of the shielding cover 1002 cooperates with the second sealing gasket 1006 to fit tightly with the optical lens to form a closed-loop sealed space, ensuring that the laser beam is completely confined within the processing area, acting vertically on the lens surface, and performing precise processing on the lens. At the same time, it prevents laser leakage and ensures the safety of the operator. After the laser processing is completed, as the turntable 4 continues to rotate and the conveying mechanism 2 continues to work, when the transmission roller 205 rotates, the fan blade 1409 is driven by the transmission shaft 1407 and the bevel gear 1404 to rotate at high speed in the connecting air duct 1403, generating suction to suck in the dust generated by the processing. The dust enters the dust collecting box 1406 through the U-shaped suction pipe 1401, the first connecting pipe 1402, the connecting air duct 1403, and the second connecting pipe 1405. A detachable filter bag is provided inside the dust collecting box 1406 to filter and collect the dust. The filter screen 1411 at the exhaust port 1410 prevents dust from leaking out, keeps the air in the workshop clean, and prevents dust from affecting the normal operation of the equipment. After completing the laser processing and dust removal, the rotating table 4 continues to rotate, and the processed lens is sent to the top of the output belt 204. Driven by the transmission roller 205, the output belt 204 transports the lens to the discharge end of the equipment, completing the entire optical lens processing process.
