Abstract

This invention relates to the field of glass production and processing technology, specifically to a glass lens milling equipment and processing technology based on CNC precision carving. It includes an outer support, a rotating table rotatably connected to the outer support, and a CNC milling mechanism mounted on the upper side of the outer support and positioned above the rotating table. Multiple fixing discs for adsorbing and fixing several glass lenses are arranged in a circular array on the upper side of the rotating table. Since fixing discs correspond to the loading, milling, cleaning, and unloading stations on the rotating table, the positions of the fixing discs can be switched synchronously after the rotating table rotates.

Description

Technical Field

[0001] This invention relates to the field of glass production and processing technology, specifically to a glass lens milling equipment and processing technology based on CNC precision carving. Background Technology

[0002] Existing CNC engraving equipment generally adopts a single-station fixed mode, which can only process a single glass substrate at a time. Traditional fixing methods rely on UV adhesive bonding or single-point vacuum adsorption, which cannot meet the simultaneous placement and processing of multiple glass lenses. Moreover, the glass debris and dust residue generated during processing can cause a chain reaction of problems, requiring machine shutdown and manual cleaning. The cleaning effect is generally poor and the equipment utilization rate is low. After cleaning, the fixture and lens need to be transferred to separate equipment for drying, and secondary handling increases the risk of contamination. It is not possible to quickly and deeply clean and dry the glass lenses and related accessories at the same time. The overall milling process is slow and the efficiency of the finished product needs to be improved. Therefore, it is necessary to propose a glass lens milling equipment and processing technology based on CNC engraving to further improve and optimize the existing technology. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a glass lens milling equipment and processing technology based on CNC precision carving, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a glass lens milling equipment based on CNC precision carving, comprising an outer support, a rotating table rotatably connected to the outer support, and a CNC milling mechanism disposed above the rotating table and installed on the upper side of the outer support. The rotating table is provided with a ring array of multiple fixing plates for adsorbing and fixing several glass lenses. The four sides of the rotating table are provided with a loading station, a milling station, a cleaning station and an unloading station in sequence corresponding to the fixing plates.

[0005] The cleaning station includes a sealing and blowing device that is lifted and mounted on an outer support. After the sealing and blowing device moves downward, it seals and covers the fixed plate, and cleans and dries multiple glass lenses on the fixed plate.

[0006] The sealed blowing and washing device includes an outer shell with an inner slot in the middle of its lower side for fitting onto the upper side of a fixed plate. A working chamber is connected above the inner slot, and a water receiving trough is connected to the outer periphery of the upper side of the inner slot. A water chamber and an installation chamber are separately and sealed inside the upper side of the outer shell. The installation chamber is located above the working chamber, and a water spray mechanism and a blower mechanism facing the working chamber are installed inside the installation chamber. A water filtration and circulation mechanism is installed on one side of the outer shell, and an ultrasonic oscillator and a water heater are installed on the side wall of the working chamber.

[0007] A rotating plate is rotatably mounted on the top of the fixed plate, and multiple negative pressure suction cups for adsorbing glass lenses are embedded on the upper side of the rotating plate. A shaft tube is fixed at the bottom of the rotating plate, and the cavity of the shaft tube is connected to each negative pressure suction cup. The shaft tube extends downward from the middle of the fixed plate to the bottom of the rotating platform. A drive mechanism for driving the shaft tube to rotate is installed on the lower side of the rotating platform. A suction pump is installed at the bottom of the rotating platform, and an air pipe is installed at the suction end of the suction pump. The air pipe is rotatably and sealingly inserted into the bottom of the shaft tube for connection.

[0008] A further improvement based on the above technical solution is that the drive mechanism includes a driven gear installed on the outer periphery of the bottom of the shaft tube and a rotary motor installed on the bottom of the rotating table. The shaft end of the rotary motor is equipped with a driving gear, and the driving gear meshes with the driven gear for transmission.

[0009] A further improvement based on the above technical solution is that an outer stepped surface is horizontally provided on the outer periphery of the middle part of the fixed plate, and an inner protruding edge is provided on the inner side of the top of the inner slot. The bottom of the inner protruding edge is adapted to fit against the outer stepped surface, and a sealing gasket is laminated at the bottom of the inner protruding edge. The inner protruding edge is tightly fitted to the outer stepped surface through the sealing gasket.

[0010] A further improvement based on the above technical solution is that the outer periphery of the fixed plate on the upper side of the outer step surface is provided with an inclined surface, and an inner groove is provided on the upper side of the inclined surface. A layer of rubber waterproofing surface is laminated on the inner side of the water receiving groove, and a rubber protruding ring is provided on the inner edge of the rubber waterproofing surface. The rubber protruding ring protrudes between the inner slot and the working cavity, and the diameter of the rubber protruding ring is smaller than the diameter of the inner groove.

[0011] A further improvement to the above technical solution is that when the outer shell moves downward, the rubber convex ring deforms as it passes the outer periphery of the fixed disk, allowing the inner diameter of the rubber convex ring to tightly fit the outer wall of the fixed disk. When the inner edge of the rubber convex ring passes the inner groove, it elastically resets and tightens itself on the inner groove. Meanwhile, the lower side of the rubber convex ring adaptively and elastically adheres to the upper side of the inclined surface during the downward movement, thereby achieving a preliminary seal until the sealing gasket on the lower side of the inner convex edge presses against the outer step surface of the fixed disk, achieving a double seal.

[0012] A further improvement based on the above technical solution is that the water filtration and circulation mechanism includes a return water pipe installed on the outside of the outer casing and connected at both ends to the bottom of the water receiving tank and the top of the water chamber, respectively. A filter for filtering the liquid in the water receiving tank is installed on the lower side of the return water pipe, and a return water pump for pumping the liquid filtered by the filter back to the water chamber is installed on the upper side of the return water pipe.

[0013] A heat pipe assembly for exhaust is also installed on one side of the outer casing. The heat pipe assembly includes an air outlet valve installed on the upper side of the water receiving tank, and an exhaust pipe is connected to the outer end of the air outlet valve. The exhaust pipe is spaced around the outer periphery of the return water pipe, and a lower box is connected to the bottom of the exhaust pipe. The filter is located inside the lower box.

[0014] A further improvement based on the above technical solution is that the water spraying mechanism includes a water pump installed in the water chamber. The water outlet end of the water pump is disposed through the installation cavity, and the water outlet end of the water pump is connected to a plurality of L-shaped water pipes in a ring array. The end of each L-shaped water pipe penetrates vertically through the bottom of the installation cavity and is located at the top of the working cavity, and a nozzle is installed at the end of the L-shaped water pipe.

[0015] The blower mechanism includes a drying hot air blower installed in the mounting cavity. The air inlet of the drying hot air blower is connected to the outside of the outer casing, and the air outlet of the drying hot air blower is connected to multiple L-shaped air outlet pipes arranged in a ring array through a pipe. The ends of the L-shaped air outlet pipes penetrate vertically through the bottom of the mounting cavity and are located at the top of the working cavity. The L-shaped water outlet pipes and L-shaped air outlet pipes are staggered.

[0016] A further improvement based on the above technical solution is that an interval cavity is provided between the water chamber and the water receiving tank. The interval cavity is located on the outer periphery of the working chamber, and the ultrasonic oscillator and the water heater are installed on the side wall of the working chamber inside the interval cavity. A liquid level sensor is installed on the inner wall of the water chamber at a position higher than the fixed plate.

[0017] A further improvement based on the above technical solution is that the outer support is equipped with a rotating limiting plate that is spaced apart vertically in the middle, and the outer circumference of the rotating table is rotatably positioned between the two rotating limiting plates. The outer support is equipped with a telescopic rod to connect with the outer shell of the sealing blowing and washing device for lifting and lowering.

[0018] A processing technology for glass lens milling equipment based on CNC precision engraving includes the following steps:

[0019] S1: Loading stage: By placing multiple glass lenses on the negative pressure suction cups of the fixed plate at the loading station, the suction pump connected to the fixed plate starts to work, causing the air tube, shaft tube and each negative pressure suction cup to generate negative pressure to adsorb and fix each glass lens.

[0020] S2: Milling stage; After adsorption and fixation, the rotary table rotates the fixed plate on the loading station to below the CNC milling mechanism of the milling station, so that the CNC milling mechanism can mill multiple glass lenses separately without the need for individual pick-up and drop-off.

[0021] S3: Dust blowing stage: After the milling is completed, the fixed plate of the milling is rotated to the bottom of the sealing and blowing device of the cleaning station by the rotating table. The sealing and blowing device first blows air downwards using the blower mechanism to initially blow away the dust particles on each glass lens and the upper side of the fixed plate. Then the entire sealing and blowing device moves downwards to cover the fixed plate and is connected to the outer periphery of the outer shell in multiple layers to form a sealed space in the working chamber.

[0022] S4: Preliminary water circulation spray washing stage: At this time, the blower mechanism is turned off, and the water spray mechanism is turned on to perform a preliminary rinse on the glass lenses held by each negative pressure suction cup. This rinse washes away larger dust particles, and in conjunction with the drive mechanism, it drives the shaft tube and rotating plate to rotate, so that each negative pressure suction cup holds the glass lens and rotates, allowing the water flow to be sprayed fully and evenly onto each mirror surface. Meanwhile, the wastewater is guided to the activated water filtration and circulation mechanism to filter and recycle the water back to the water tank.

[0023] S5: Ultrasonic cleaning stage: After the initial spray rinsing, the water filtration and circulation mechanism is turned off, so that the water at the bottom of the working chamber is closed and does not flow out. At this time, the water flowing downward is relatively clean, the water level in the working chamber rises and submerges each glass lens. Then, the ultrasonic oscillator works to make the glass lens, the fixed plate and the inner wall of the working chamber perform ultrasonic cleaning simultaneously. After cleaning, the water filtration and circulation mechanism is turned on again to recycle and filter the water, and the water inside the working chamber is pumped away.

[0024] S6: Rotary drying stage: At this time, turn on the blower mechanism again and, in conjunction with the drive mechanism, rotate the rotating plate back and forth to quickly and evenly dry the glass lens that is attached and fixed by the negative pressure suction cup, and simultaneously dry the fixing plate and the working chamber for the next use.

[0025] S7: Unloading stage: After cleaning and drying, the rotary table rotates again, allowing the fixed plate of the cleaning station to rotate to the front unloading station. Then, the suction pump controls the release of air from each negative pressure suction cup, and the sheet is picked up and unloaded manually or by a robot. After unloading, the rotary table rotates again to rotate the empty fixed plate back to the loading station for repeated operation. The loading station, milling station, cleaning station and unloading station can be used simultaneously.

[0026] By adopting the above-described technical solution, the present invention has the following advantages over the prior art:

[0027] This invention has a clever structure and is simple and convenient to use. By having fixed plates corresponding to the rotating tables of the loading station, milling station, cleaning station and unloading station, the position of each fixed plate can be switched synchronously after the rotating table rotates, so that the loading station, milling station, cleaning station and unloading station can work synchronously. Moreover, multiple glass lenses can be placed and fixed on the fixed plates at the same time for the CNC milling mechanism to process and clean, without the need for manual single fixed point operation. This can quickly improve the milling and cleaning efficiency of glass lenses and the use effect of the equipment.

[0028] The sealed blowing device in the cleaning station sprays water and blows air downwards through a water spray mechanism and a blower mechanism. The water spray mechanism sprays water after the working chamber is sealed, using the water flow to wash away the dust on the surface of the glass lens downwards. At the same time, the use of the drive mechanism allows each glass lens to be rotated and sprayed, which improves the cleaning range and uniformity of the lens. During this process, the water filtration and circulation mechanism can be used to filter and recycle the water in the water tank back to the water chamber for reuse, so that the water level can be kept relatively balanced and will not overflow. When it is necessary to switch to the cleaning mode for deep cleaning, the operation of the water filtration and circulation mechanism can be stopped. At this time, the position is raised until the glass lens is submerged. The ultrasonic oscillator is used to perform ultrasonic cleaning on the submerged glass lens and the fixed plate, which can remove the grease marks and dust adhering to the surface, further improving the cleaning effect and efficiency of the lens.

[0029] When the working chamber is not sealed, the blower mechanism can initially blow away the dust and debris on the surface of the glass lens and the fixed plate, reducing the workload of the filter and preventing the dust and debris from affecting the tightness of the outer shell when it covers the outer periphery of the fixed plate. After the water spraying mechanism has finished cleaning the glass lens, the blower mechanism can dry it again. At the same time, the drive mechanism can rotate each glass lens to dry it evenly, improving the drying efficiency. Meanwhile, the hot air blown out can enter the pipe heating group, which heats the return water pipe and the filter, reducing the growth of bacteria in the return water pipe and the filter, which is beneficial to the cleanliness of the return water.

[0030] In addition, when the outer shell moves downwards to fit the fixed plate, the rubber convex ring first deforms as it passes the outer circumference of the fixed plate, allowing its inner diameter to fit tightly against the outer wall of the fixed plate. When the inner edge of the rubber convex ring passes the inner groove, it elastically resets and tightens itself on the inner groove. This prevents water from easily flowing to the edge of the rubber convex ring in the inner groove during spraying, thus improving the leak-proof effect. Meanwhile, the lower side of the rubber convex ring adapts and elastically adheres to the upper side of the inclined surface during the downward movement, achieving a preliminary seal. This continues until the sealing gasket on the lower side of the inner convex edge presses against the outer step surface of the fixed plate, achieving a double seal. This greatly improves the sealing performance between the fixed plate and the outer shell, providing a solid foundation for washing and drying. Attached Figure Description

Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figure 1-7As shown, this invention provides a technical solution for a glass lens milling machine based on CNC precision machining: it includes an outer support 1, a rotating table 2 rotatably connected to the outer support 1, and a CNC milling mechanism 4 mounted on the upper side of the outer support 1 and located above the rotating table 2. The CNC milling mechanism 4 is equipped with a vision camera to accurately determine the adsorption position of each glass lens, facilitating precise milling. Multiple fixing disks 3 for adsorbing and fixing several glass lenses are mounted in a circular array on the upper side of the rotating table 2. The four sides of the rotating table 2 are sequentially provided with a loading station, a milling station, a cleaning station, and an unloading station corresponding to the fixing disks 3. The cleaning station includes a sealing and blowing device 5 that is lifted and lowered on the outer support 1. After the sealing and blowing device 5 moves downward, it seals and covers the fixing disks 3, and cleans the multiple glass lenses on the fixing disks 3. The cleaning and drying process is carried out. Specifically, the sealed blowing and washing device 5 includes a housing 51. The lower middle part of the housing 51 has an inner slot 52 for fitting onto the upper side of the fixed plate 3. The upper part of the inner slot 52 is connected to a working chamber 53, and the upper outer periphery of the inner slot 52 is connected to a water receiving tank 56. The upper part of the housing 51 is separately and sealed with a water chamber 54 and an installation cavity 55. The installation cavity 55 is located above the working cavity 53, and a water spraying mechanism and a blowing mechanism facing the working cavity 53 are installed inside the installation cavity 55. A water filtration and circulation mechanism is installed on one side of the housing 51. An ultrasonic oscillator 581 and a water heater are installed on the side wall of the working cavity 53. The water heater mainly heats the water inside the working cavity 53 as needed, and the ultrasonic oscillator 581 enables the working cavity 53 to perform ultrasonic water washing.

[0042] The fixed disk 3 has a rotating plate 31 sealed and rotatably mounted on its top. Multiple negative pressure suction cups 32 for adsorbing glass lenses are embedded in the upper side of the rotating plate 31. A shaft tube 33 is fixed to the bottom of the rotating plate 31, and the cavity of the shaft tube 33 communicates with each negative pressure suction cup 32. The shaft tube 33 extends downwards from the middle of the fixed disk 3 to the bottom of the rotating platform 2. A drive mechanism for driving the shaft tube 33 to rotate is mounted on the lower side of the rotating platform 2. The drive mechanism includes a driven gear 331 mounted on the outer periphery of the bottom of the shaft tube 33 and a rotary motor 332 mounted on the bottom of the rotating platform 2. The shaft end of the rotary motor 332... The rotating table 2 is equipped with a drive gear 333, which meshes with the driven gear 331 for transmission. Therefore, the rotating motor 332 drives the drive gear 333 to mesh with the driven gear 331, so that both the shaft tube 33 and the rotating plate 31 can rotate. A suction pump 34 is installed at the bottom of the rotating table 2. The suction end of the suction pump 34 is equipped with an air pipe 35. The air pipe 35 is rotatably sealed and inserted into the bottom of the shaft tube 33 for connection. Therefore, the negative pressure suction cup 32 can synchronously adsorb the glass lens as the rotating plate 31 rotates. In this way, it can be used in conjunction with the water spray mechanism and the blower mechanism to efficiently clean and dry the glass lens during rotation.

[0043] Furthermore, the outer periphery of the middle part of the fixed plate 3 is horizontally provided with an outer stepped surface 36, and the inner side of the top of the inner slot 52 is provided with an inner protruding edge 521. The bottom of the inner protruding edge 521 is adapted to fit against the outer stepped surface 36, and a sealing gasket 522 is laminated at the bottom of the inner protruding edge 521. The inner protruding edge 521 is tightly fitted to the outer stepped surface 36 through the sealing gasket 522. The outer periphery of the fixed plate 3 on the upper side of the outer stepped surface 36 is provided with an inclined surface 37, and an inner groove 38 is provided on the upper side of the inclined surface 37. The inner side of the water receiving tank 56 is laminated with a layer of rubber waterproof surface 57, and a rubber protruding ring part 571 is provided on the inner edge of the rubber waterproof surface 57. The rubber protruding ring part 571 protrudes from the inner slot. Between the outer shell 52 and the working chamber 53, and since the diameter of the rubber convex ring 571 is smaller than the diameter of the inner groove 38, when the outer shell 51 moves downward, the rubber convex ring 571 deforms as it passes the outer periphery of the fixed disk 3, so that the inner diameter of the rubber convex ring 571 is tightly fitted onto the outer wall of the fixed disk 3. When the inner edge of the rubber convex ring 571 passes the inner groove 38, it elastically resets and tightens onto the inner groove 38. Meanwhile, the lower side of the rubber convex ring 571 adaptively and elastically adheres to the upper side of the inclined surface 37 during the downward displacement, thereby achieving a preliminary seal until the sealing gasket 522 on the lower side of the inner convex edge 521 presses against the outer step surface 36 of the fixed disk 3, achieving a double seal.

[0044] Furthermore, the water filtration and circulation mechanism includes a return water pipe 7 installed on the outside of the outer casing 51 and connected at both ends to the bottom of the water receiving tank 56 and the top of the water chamber 54, respectively. A filter 71 for filtering the liquid in the water receiving tank 56 is installed on the lower side of the return water pipe 7, and a return water pump 72 for pumping the liquid filtered by the filter 71 back to the water chamber 54 is installed on the upper side of the return water pipe 7, thereby realizing water circulation filtration. A pipe heat exchanger 8 for exhaust is also installed on one side of the outer casing 51. The pipe heat exchanger 8 includes an air outlet pipe installed on the upper side of the water receiving tank 56. The valve 80 is connected to an exhaust pipe 81 at its outer end. The exhaust pipe 81 is sleeved around the outer periphery of the return water pipe 7 at intervals. The bottom of the exhaust pipe 81 is connected to a lower box 82. The filter 71 is located inside the lower box 82. The exhaust pipe valve 80 has an opening. This configuration can guide the hot air blown outward by the blower mechanism to the exhaust pipe valve 80, and then enter the exhaust pipe 81 and the lower box 82 through the exhaust pipe valve 80. The hot air is used to heat the return water pipe 7 and the filter 71 simultaneously to reduce the growth of bacteria in the return water pipe 7 and the filter 71.

[0045] In the above technical solution, the water spraying mechanism includes a water pump 541 installed in the water chamber 54. The water outlet end of the water pump 541 is installed through the mounting cavity 55, and the water outlet end of the water pump 541 is connected to a plurality of L-shaped water outlet pipes 542 in a ring array. The ends of each L-shaped water outlet pipe 542 penetrate vertically through the bottom of the mounting cavity 55 and are located at the top of the working cavity 53. A nozzle 543 is installed at the end of the L-shaped water outlet pipe 542. The blowing mechanism includes a drying hot air blower 551 installed in the mounting cavity 55. The air inlet end of the drying hot air blower 551 is connected to the outside of the outer casing 51, and the blowing end of the drying hot air blower 551 is connected to a plurality of L-shaped air outlet pipes 552 distributed in a ring array through a pipe. The ends of the L-shaped air outlet pipes 552 penetrate vertically through the bottom of the mounting cavity 55 and are located at the top of the working cavity 53. The L-shaped water outlet pipes 542 and the L-shaped air outlet pipes 552 are staggered and distributed in a reasonable spatial layout, so that water and air can enter from the upper side of the working cavity 53.

[0046] Furthermore, an interval cavity 58 is provided between the water chamber 54 and the water receiving tank 56. The interval cavity 58 is located on the outer periphery of the working chamber 53, and the ultrasonic oscillator 581 and the water heater are installed on the side wall of the working chamber 53 inside the interval cavity 58, which facilitates the later maintenance and replacement of this component. A liquid level sensor 531 is installed on the inner wall of the water chamber 54 at a position higher than the fixed plate 3 to detect the water level. Moreover, a rotating limit plate 10 with upper and lower intervals is installed in the middle of the outer bracket 1, and the outer periphery of the rotating platform 2 is rotatably set between the two rotating limit plates 10. In this way, the rotating platform 2 can rotate more stably between the two rotating limit plates 10, which can also improve the structural support stability of the outer bracket 1. The outer bracket 1 is equipped with a telescopic rod 6 to connect with the outer shell 51 of the sealing blowing device 5 for lifting and lowering. The end of the telescopic rod 6 is locked to the top of the outer shell 51, thereby realizing the overall lifting and lowering of the outer shell 51 and its internal structure.

[0047] The rotating platform 2 has a water guide hole on its top surface and an upward-facing convex edge on its surface to prevent water leakage from all four sides. A wastewater box is installed at the bottom of the rotating platform 2 corresponding to the water guide hole to collect dust and wastewater. The rotating platform 2 is driven to rotate by a rotating motor installed on the base. Specifically, it can be driven by gear meshing or by a transmission belt. Since the structure is relatively conventional and simple, it will not be described in detail here.

[0048] A processing technology for glass lens milling equipment based on CNC precision engraving includes the following steps:

[0049] S1: Loading stage: By placing nineteen glass lenses on the negative pressure suction cups 32 of the fixed plate 3 at the loading station, the suction pump 34 connected to the fixed plate 3 starts to work, so that the air pipe 35, shaft pipe 33 and nineteen negative pressure suction cups 32 generate negative pressure to adsorb and fix each glass lens.

[0050] S2: Milling stage; After adsorption and fixation, the rotating table 2 rotates the fixed plate 3 on the loading station to below the CNC milling mechanism 4 of the milling station, so that the CNC milling mechanism 4 can mill the edges of the nineteen glass lenses respectively, without the need for individual pick-up and drop processing;

[0051] S3: Dust blowing stage: After milling is completed, the milled fixed plate 3 is rotated by the rotary table 2 to a position below the sealing and blowing device 5 in the cleaning station. The sealing and blowing device 5 first uses the blower mechanism to operate the drying hot air blower 551, causing the L-shaped air outlet pipes 552 distributed in a ring array to blow air downwards, initially blowing away the dust particles on each glass lens and the upper side of the fixed plate 3. Then, the entire sealing and blowing device 5 moves downwards to cover the fixed plate 3. When the outer shell 51 moves downwards to cover the fixed plate 3, the rubber convex ring 571 first deforms as it passes the outer periphery of the fixed plate 3, allowing the inner diameter of the rubber convex ring 571 to tightly fit the outer wall of the fixed plate 3. When the inner edge of the rubber convex ring 571 passes through the inner groove 38, it elastically resets and tightens on the inner groove 38. This makes it difficult for water to flow to the edge of the rubber convex ring 571 in the inner groove 38 during the subsequent spraying, thus improving the water-proof effect. Meanwhile, the lower side of the rubber convex ring 571 adaptively and elastically adheres to the upper side of the inclined surface 37 during the downward displacement, thereby achieving a preliminary seal until the sealing gasket 522 on the lower side of the inner convex edge 521 presses against the outer step surface 36 of the fixed plate 3, achieving a double seal. This greatly improves the sealing performance between the fixed plate 3 and the outer shell 51, allowing the working cavity 53 to form a sealed space and reducing the possibility of water and air leakage.

[0052] S4: Preliminary water circulation spray washing stage: At this time, the blower mechanism is turned off, and the water spray mechanism is turned on to perform preliminary rinsing on the glass lenses held by each negative pressure suction cup 32. The water spray mechanism mainly uses the water pump 541 to spray water downwards from the nozzle 543 of the L-shaped water outlet pipe 542 for rinsing. This rinsing washes away larger dust particles, and in conjunction with the drive mechanism's rotary motor 332, drives the active gear 333 to rotate and mesh with the driven gear 331 of the transmission shaft tube 33, thereby driving the shaft tube 33 and the rotating plate 31 to rotate, so that each negative pressure suction cup 32 can rotate while holding the glass lens, allowing the water flow to be sprayed fully and evenly onto each mirror surface. The wastewater is guided to the water receiving tank 56 through the upper surface of the rubber convex ring 571, and the return water pump 72 of the water filtration circulation mechanism is turned on. The water at the bottom of the water receiving tank 56 is drawn out through the return water pipe 7 and filtered through the filter 71. The filtered water is then recycled back to the water tank to ensure that the water level does not rise and to provide sufficient circulating water for the water chamber 54.

[0053] S5: Ultrasonic cleaning stage: After the initial spray rinsing, the return water pump 72 of the water filtration circulation mechanism is turned off, so that the bottom of the working chamber 53 is closed and does not flow out. At this time, the water flowing downward is relatively clean. The water spraying mechanism causes the water level in the working chamber 53 to rise, submerging each glass lens and being detected by the liquid level sensor 531. Then the water spraying stops. Then, the ultrasonic oscillator 581 works to make the glass lens, the fixed plate 3 and the inner wall of the working chamber 53 be ultrasonically cleaned simultaneously. After the cleaning is completed, the water filtration circulation mechanism is turned on again to recycle and filter the water, and the water inside the working chamber 53 is pumped out, thus completing the deep cleaning operation.

Then, the entire outer shell 51 is disengaged from the fixed plate 3 by the action of the telescopic rod 6.

[0055] S7: Unloading stage: After cleaning and drying, the rotary table 2 rotates again, allowing the fixed plate 3 of the cleaning station to rotate to the front unloading station. Then, the suction pump 34 controls the release of air from each negative pressure suction cup 32, and the sheet is picked up and unloaded manually or by a robot. After unloading, the rotary table 2 rotates to rotate the empty fixed plate 3 back to the loading station for repeated operation. The loading station, milling station, cleaning station and unloading station can be used simultaneously.
