Description

Technical Field

[0001] The invention relates to an optical glass ultrasonic cleaning device and method. Background Art

[0002] Optical glass is often cleaned using ultrasound, which creates cavitation, acceleration, and a straight-through flow within the cleaning fluid. This disperses, emulsifies, and peels off the dirt layer on the surface of the optical glass, achieving the cleaning purpose. Ultrasonic cleaning devices for optical glass mostly utilize independent ultrasonic cleaning tanks. After ultrasonic cleaning, the tank is laterally moved to a rinse station. After the rinse operation is complete, it is laterally moved to a drying device. The entire cleaning device occupies a large amount of lateral space, and optical glass is often left in a static state during ultrasonic cleaning, requiring a long time to achieve the cleaning effect. Therefore, based on current cleaning devices, further research and development can be conducted on the structure and operation of the cleaning device. Summary of the Invention

[0084] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0085] See Figure 1 As shown in FIG. 13 , an optical glass ultrasonic cleaning device is used for cleaning the surface of optical glass. The device includes a cleaning cabinet 1, the interior of which is a cleaning space for containing optical glass cleaning fluid. Ultrasonic vibration plates 2 are arranged around the interior of the cleaning cabinet 1 for connecting to an external ultrasonic generator to generate ultrasonic waves within the cleaning space to clean the optical glass surface. The interconnection and arrangement of the ultrasonic vibration plates and ultrasonic generators can adopt the structures used in existing ultrasonic cleaning systems, as long as ultrasonic cleaning can be generated within the cleaning cabinet.

[0086] A lifting cabinet 3 is arranged above the cleaning cabinet 1, and the lifting cabinet 3 cover is arranged above the cleaning cabinet 1. A lifting frame 4 is arranged inside the lifting cabinet 3. When a vertical ascending or descending external force is applied to the lifting frame 4 from above the lifting cabinet 3, the lifting frame 4 can realize ascending or descending movements inside the lifting cabinet 3.

[0087] A loading assembly 5 for loading optical glass is provided in the middle of the lifting frame 4. The loading assembly 5 follows the rise and fall of the lifting frame 4. A water diversion plate 6 for collecting water dripping from the loading assembly 5 is provided at the bottom of the lifting frame below the loading assembly 5. The water diversion plate 6 has a generally flat U-shaped cross-section. Both sides of the water diversion plate 6 are ribs higher than the middle to prevent water from flowing out from both sides. The bottom wall of the water diversion plate 6 gradually tilts downward from its midline position toward both ends, so that the water on it can be diverted toward both ends through the bottom wall of the water diversion plate 6, thereby speeding up the flow of water from the water diversion plate 6.

[0088] A lift actuator 7 is located on the back of the lift cabinet 3, driving the lift frame 4 upward and downward. The drive end of the lift actuator 7 is connected to the top of the lift frame 4 via a connecting frame 8 that passes through the back of the lift cabinet 3. The lift actuator 7 utilizes a telescopic cylinder, and a notch 9 is provided on the upper back of the lift cabinet 3 to allow for access to the connecting frame 8. A protective cover is installed on the back of the lift cabinet 3, enclosing the lift actuator 7 and providing a degree of protection. Placing the lift actuator 7 on the back of the lift cabinet also reduces the vertical space occupied by the cleaning device.

[0089] Vertical guide plates 10 are fixedly provided on the inner walls on both sides of the lifting cabinet 3, and guide wheels 11 are installed on the outer side of the lifting frame 4. The side surfaces of the vertical guide plates 10 have guide grooves arranged vertically for the guide wheels 11 to be placed therein. The guide wheels 11 move in the vertical guide plates 10 to enhance the stability of the lifting frame 4 in vertical ascent and descent.

[0090] On both sides of the cleaning cabinet 1, there are respectively provided with a water collection box 12 for the water diverted by the water diversion plate 6 to flow into. The upper part of the two water collection boxes is fixedly provided with a drainage component 13 that is docked with the two ends of the water diversion plate 6. The water on the water diversion plate 6 is introduced into the water collection box 12 through the drainage component 13; the cooperation between the water diversion plate 6 and the drainage component 13 is mainly reflected in the rinsing process of the optical glass after ultrasonic cleaning, that is, the water in the rinsing process flows into the water collection box 12 through the water diversion plate 6 and the drainage component 13.

[0091] A lifting spray assembly 14 is disposed in the upper portion of the lifting frame 4 above the loading assembly 5. The lifting spray assembly 14 is used to spray cleaning water or drying gas toward the optical glass in the loading assembly 5. The lifting spray assembly 14 can rise and fall within the lifting frame 4. That is, when loading and unloading materials, the lifting spray assembly 14 rises to a high position within the lifting frame 4 without affecting the loading and unloading process. When washing and blowing the optical glass, the lifting spray assembly 14 descends downward within the lifting frame to the position of the loading assembly 5, where it washes and blows the optical glass.

[0092] Among them, the drainage assembly 13 includes a base plate 15, a movable support block 16, a fixed support block 17, a drainage plate 18, a reset spring 19, and a follower block 20; the base plate 15 is fixedly arranged on the upper end of the water collection box 12 close to the side of the washing cabinet 1 by bolts or welding, and the entire base plate 15 is arranged in a horizontal direction, and a mounting support surface is formed on the upper surface of the base plate 15; the movable support block 16 is slidably arranged on the upper surface of the base plate 15 in the horizontal direction, and a slide rail 21 is installed in the left and right directions of the upper surface of the base plate 15. The movable support block 16 is slidably assembled on the slide rail 21, and the movable support block 16 can slide toward or away from the washing cabinet 1 on the slide rail 21; the fixed support block 17 is fixedly installed on the upper surface of the base plate 15 by bolts, the fixed support block 17 is close to the side of the water collection box 12, and the movable support block 16 is close to the side of the washing cabinet 1, and moves toward or away from the upper end of the washing cabinet 1.

[0093] The return spring 19 is arranged between the movable support block 16 and the fixed support block 17 and is compressed by the two. A guide column 22 is fixed on the side of the fixed support block 17 facing the movable support block 16, and a vertical plate 23 is fixedly assembled on the outer side of the upper end of the movable support block 16. The guide column 22 passes through the vertical plate 23, and the return spring 19 is sleeved on the guide column 22. The outer end of the return spring 19 presses against the side of the fixed support block 17, and the inner end presses against the side of the movable support block 16, so that when the movable support block 16 moves toward the fixed support block 17, the return spring 19 can be compressed and store force.

[0094] The follower block 20 is fixedly assembled on the side of the mobile support block 16 close to the washing cabinet 1; the drainage plate 18 is fixedly assembled on the mobile support block 16 and moves together with the mobile support block 16. The drainage plate 18 adopts an inclined design with the outer end lower than the inner end to facilitate drainage toward the water collection box 12. The extension point of the outer end of the drainage plate 18 toward the outside is lower than the upper end box opening of the water collection box 12 to ensure that the water on the drainage plate 18 can flow into the water collection box 12.

[0095] The width of the end of the deflector plate 18 near the water deflector plate 6 is at least greater than the width of the end of the water deflector plate 6. The water deflector plate 6 is equipped with a pusher 24 that, when in contact with the follower block 20, exerts an outward thrust on the follower block 20, compressing and accumulating the force of the return spring 19. Pusher 24 is a pusher wheel or pusher ramp mounted on the outer side of the water deflector plate 6 via a mounting bracket 70. The outer periphery of the pusher wheel extends beyond the outer end surface of the water deflector plate 6, ensuring that pusher 24 effectively cooperates with the follower block 20.

[0096] In some embodiments, a first stop block 25 is fixedly provided on the bottom plate 15, and a second stop block 26 is fixedly provided on the side of the movable support block 16. The first stop block 25 blocks the second stop block 26 to constrain the moving distance of the movable support block 16 toward the cleaning cabinet 1, thereby preventing the movable support block 16 from moving too far.

[0097] In some embodiments, one side of the guide plate 18 can be fixed to the side of a movable support block 16, so that the other side of the guide plate 18 is suspended, which can reduce the use of related components. This structure only needs to slightly increase the thickness of the guide plate 18 to improve its impact resistance and deformation resistance.

[0098] In some embodiments, both sides of the guide plate 18 are respectively fixed on the movable support block 16, and other components in the guide assembly 13 except the guide plate 18 are also provided, so that both sides of the guide plate 18 can be stably supported, thereby enhancing the stability of the movement of the guide plate 18 and the stability of the operation of the guide assembly 13.

[0099] In some embodiments, the side of the follower block 20 close to the cleaning cabinet 1 has an isosceles trapezoidal follower portion 27, which is turned 90 degrees clockwise and arranged on one side of the follower block 20; the follower portion 27 includes a first inclined surface 28, a second inclined surface 29, a top vertical surface 30, and a bottom vertical surface 31; the first inclined surface 28 is arranged to be inclined downward from the top surface of the follower block 20 toward the bottom of the cleaning cabinet 1; the second inclined surface 29 is arranged to be inclined upward from the bottom surface of the follower block 20 toward the top of the cleaning cabinet 1; the top vertical surface 30 is vertically arranged between the outer side of the first inclined surface 28 and the outer side of the second inclined surface 29, the upper end of the top vertical surface 30 is connected to the lower end of the first inclined surface 28, and the upper end is connected to the upper end of the second inclined surface 29; the bottom vertical surface 31 is vertically arranged between the inner side of the first inclined surface 28 and the inner side of the second inclined surface 29, and the bottom vertical surface 31 is fixed to the side of the follower block 20. The follower portion 27 and the follower block 20 may be connected in a detachable fixed connection manner to facilitate regular maintenance and replacement of the follower portion 27 .

[0100] In some embodiments, when the deflector plate 18 is in the reset state, after projecting from top to bottom, the distance D1 between the front end surface of the deflector plate 18 and the outermost surface of the water deflector plate 6 is less than the distance D2 between the top vertical surface 30 and the bottom vertical surface 31; the vertical length of the top vertical surface 30 is greater than the end height of the water deflector plate 6. When the pusher 24 descends and contacts the first inclined surface 28, there is a certain distance between the water deflector plate 6 and the deflector plate 18 in the vertical direction, and no collision occurs. When the pusher 24 continues to descend and contacts the top vertical surface 30, the pusher 24 pushes the follower 27 toward the rear. After projecting from top to bottom, there is a gap between the end surface of the water deflector plate 6 and the end surface of the deflector plate 18, so that the water deflector plate 6 can move downward smoothly without obstruction. When the pusher 24 descends and contacts the second inclined surface 29, the deflector plate 18 It is already above the water guide plate 6, and will not collide with the water guide plate 6 during the subsequent reset. Therefore, through the cooperation of the pushing member 24 and the follower 27, it can be ensured that the water guide plate 6 will not collide with the guide plate 18 during the up and down movement; when the lifting frame rises to the flushing position, the pushing member 24 and the first inclined surface 28 are disengaged. At this time, there is a certain overlap between the end of the guide plate 18 and the end of the water guide plate 6 after projection, so that the water on the water guide plate 6 can flow onto the guide plate 18.

[0101] In some embodiments, when the pusher 24 is not in contact with the first inclined surface 28 / second inclined surface 29, a portion of the pusher 24 and the first inclined surface 28 / second inclined surface 29 still overlap when projected from top to bottom or bottom to top, allowing the pusher 24 to smoothly contact the follower 27 and effectively push the follower 27 backward. The inclination angle of the first inclined surface 28 / second inclined surface 29 is approximately 30 degrees to avoid the generation of a large collision force between the pusher 24 and the follower 27 due to an excessively large angle, which could cause mutual damage, and to avoid the need for a longer inclined surface for transition due to a smaller angle, which would reduce the sensitivity of the cooperation between the follower 27 and the pusher 24.

[0102] In some embodiments, the loading assembly 5 includes a supporting plate 32, a positioning plate 33, and a loading plate 34, all of which are arranged in a horizontal direction; the side of the supporting plate 32 is fixedly connected to the middle part of the lifting frame 4, and connecting blocks 35 are respectively fixed on at least the two outer sides of the middle part of the supporting plate 32. The connecting blocks 35 are connected to the connecting seat 36 in the lifting frame 4 by bolts, and the positioning plate 33 is clamped on the supporting plate 32 to facilitate the loading and unloading of the positioning plate 33 from the supporting plate 32.

[0103] The loading plate 34 is rotatably mounted on the positioning plate 33, meaning that the loading plate 34 can rotate on the positioning plate 33. A drive mechanism is provided on the positioning plate 33 to drive the loading plate 34 to reciprocate within a rotational angle of no greater than 30 degrees. During the ultrasonic cleaning process, the drive mechanism can cause the loading plate 34 to rotate slowly and reciprocally at a small angle, thereby causing the optical glass to shift position within the ultrasonic cleaning solution. This allows the ultrasonic wave to better clean the optical glass surface, increasing cleaning efficiency and effectiveness. The reciprocating frequency and speed of the loading plate must not impact the rotation of the optical glass; as long as the loading plate rotates to shift the position of the optical glass, it is sufficient.

[0104] There are multiple small loading spaces 37 in the loading plate 34, and a loading mesh bag 38 for placing optical glass in each small loading space 37 is hung on the loading plate 34. The loading mesh bag 38 extends toward the bottom of the loading assembly 5, so that during the ultrasonic cleaning process, the optical glass in the loading mesh bag 38 can be immersed below the liquid surface and effectively cleaned by ultrasonic waves.

[0105] In some embodiments, the supporting plate 32 adopts a square structure, and has a rectangular supporting opening 39 in the supporting plate 32, and has a card slot 40 on the four sides of the supporting opening 39; the outer periphery of the positioning plate 33 extends outward to form a card edge 41 adapted to the card slot 40. After the card edge 41 is placed in the corresponding card slot 40, the positioning plate 33 is installed on the supporting plate 32. Other detachable connection methods can also be used between the positioning plate 33 and the supporting plate 32 to further increase the connection, such as magnetic, bolt connection, etc., to ensure the stability of the connection between the positioning plate 33 and the supporting plate 32.

[0106] The middle part of the positioning plate 33 has a circular positioning opening 42 that passes through the upper and lower surfaces; the outer periphery of the loading plate 34 is a circle that adapts to the positioning opening 42, the upper part of the outer periphery of the loading plate 34 is an annular clamping portion 43 that is stuck on the upper surface of the positioning plate 33, and the lower part of the outer periphery is an annular inserting portion 44 that is inserted into the positioning opening. In this way, when the loading plate 34 is placed in the positioning opening 42, the loading plate 34 has a space for rotation formed with the center of the positioning opening; that is, the outer lower end surface of the annular clamping portion 43 slides in conjunction with the upper surface of the positioning opening 42, and the outer peripheral wall of the annular inserting portion 44 slides in conjunction with the inner peripheral wall of the positioning opening 42.

[0107] The driving mechanism includes a follower 45 arranged on the upper part of the outer periphery of the loading plate 34, and an active member 46 installed at the corner of the upper surface of the positioning plate 33. The active member 46 drives the follower 45 to move, causing the loading plate 34 to rotate on the positioning plate 33 with the center of the positioning opening as the center.

[0108] In practice, the drive mechanism can be implemented using a rack and pinion system, such as a driven member 45 being an arcuate rack mounted on the outer circumference of the loading plate 34, and a driving member 46 being a gear mounted on the positioning plate 33. The gear is driven by a motor, thereby enabling the drive mechanism to drive the loading plate 34 to rotate on the positioning plate 33. Another implementation method is to use a telescopic cylinder. In this case, the driving member 46 can be a telescopic cylinder, and the driven member 45 can be a driven block mounted on the outer circumference of the loading plate 34. The telescopic end of the telescopic cylinder is movably connected to the driven block. The telescopic cylinder is extended and retracted along the tangential direction of the loading plate 34 to drive the loading plate 34 to rotate on the positioning plate 33. Thus, during the ultrasonic cleaning process, the drive mechanism can drive the loading plate to reciprocate at a certain angle on the positioning plate, thereby moving the optical glass in the cleaning solution and improving cleaning efficiency.

[0109] In some embodiments, the loading plate 34 defines a large, circular loading space. An annular carrier 47 is disposed in the center of the large loading space. The carrier 47 and the loading plate 32 share a common center. The outer periphery of the carrier 47 is provided with multiple supporting plates 48. The outer ends of the supporting plates 48 are secured to the inner periphery of the loading plate 34, while the inner ends are secured to the outer periphery of the carrier 47. The multiple supporting plates 48 are arranged in an annular pattern within the annular space formed between the inner periphery of the loading plate 34 and the outer periphery of the carrier 47, forming the aforementioned small loading spaces 37 between adjacent supporting plates 48. The arrangement of the multiple supporting plates 48 divides the large loading space into multiple small loading spaces 37, into which the optical glass is placed.

[0110] In some embodiments, the load-bearing support plate 48 is arranged horizontally, and its upper surface is the load-bearing surface. The loading mesh bag 38 includes a U-shaped bag frame 49 and a mesh bag body 50 installed on the bag frame 49. The mesh bag body 50 can be a hard mesh bag, such as a stainless steel mesh bag; the bag frame 49 is a fan-shaped structure formed by two side frames 51, an outer frame 52, and an inner frame 53. The two side frames 51 of the bag frame 49 are respectively stuck on the upper surfaces of adjacent load-bearing support plates 48 to hang the loading mesh bag 38 between adjacent load-bearing support plates 48. The outer frame 52 connects the outer ends of the two side frames 51, and the inner frame 53 connects the inner ends of the two side frames 51, and the bag mouth of the mesh bag body 50 is fixed on the bag frame 49; lifting handles 54 are fixed on both sides of the bag frame 49 to facilitate the entire loading mesh bag 38 to be taken and placed as a whole from the small loading space 37.

[0111] In some embodiments, at least one partition 55 is provided within the bag frame 49 to separate the space within the mesh bag body 50 for placing different types of optical glass, allowing them to be mixed and shuffled without causing confusion. In practice, the partition 55 can be made of stainless steel wire mesh. The partition 55 can be extended downward to a certain length to provide a corresponding vertical restraint for the optical glass.

[0112] In some embodiments, the lifting spray assembly 14 includes a buffer container 56 and a lifting drive structure 57; a supporting plate 58 is fixedly installed on the upper part of the lifting frame 4, and the lifting drive structure 57 is vertically assembled downward on the supporting plate. The lifting drive structure 57 adopts a telescopic cylinder, such as an oil cylinder, an air cylinder, an electric cylinder, etc.

[0113] The driving end of the lifting drive structure 57 is connected to the buffer container 56, driving the buffer container 56 to move upward and downward directly above the loading assembly 5. Specifically, the upper end of the buffer container 56 is mounted on a base plate 59. The base plate 58 is connected to the lifting drive structure 57. A guide rod 60 is fixedly mounted on the base plate 59. The upper end of the guide rod 60 passes through the supporting plate to form a guide, enhancing the stability of the base plate 59 and the buffer container 56 during the lifting and lowering. When purging is required, the lifting drive structure 57 drives the base plate 59 to descend, allowing the buffer container 56 to descend into place. When purging is not required, the lifting drive structure 57 drives the base plate 59 to ascend and return to its original position.

[0114] In some embodiments, the buffer container 56 has a circular outer periphery and a closed buffer cavity 61 on the inner periphery; the side of the buffer container 56 is equipped with a pipe joint 62, and the pipe joint 62 is connected to the water source pump and the dry air pump on the back of the lifting cabinet 3 through a metal hose. The water source pump and the dry air pump are connected to the metal hose by switching the switching valve to switch the water or dry gas into the buffer cavity 61; the metal hose can be connected to the back of the lifting cabinet 3 from the yield slot 9.

[0115] In some embodiments, a plurality of injection assemblies 63 are arranged in an annular manner and fixedly connected to the outer periphery of the buffer container 56, and are connected to the buffer cavity 61. One injection assembly 63 corresponds to a small loading space 37, and one injection assembly 63 is responsible for injecting the optical glass in the small loading space 37. The injection assembly 63 includes a main pipe 64 and multiple branch pipes 65. One end of the main pipe 64 is connected to the buffer cavity 61, and the other end extends radially outward along the buffer container 56. The main pipe 64 and the buffer container 56 are connected by threads to facilitate assembly and disassembly between the main pipe 64 and the buffer container 56. The main pipe 64 and the branch pipes 65 are fixed by welding. The branch pipes 65 can be curved or straight. The fluid in the buffer cavity 61 is sent to each branch pipe 65 through the main pipe 64. By arranging the buffer cavity 61 and the main pipe 64 in an annular manner on the outer periphery of the buffer cavity 61, the fluid in the buffer cavity 61 can be evenly introduced into the main pipe 64, thereby improving the balance of the injection flow of each injection assembly 63.

[0116] In some embodiments, the volume of the buffer space is at least twice or more than the volume of all the injection components 63 to ensure that there is sufficient fluid in the buffer space and that corresponding pressure can be generated toward the injection component 63, so that the injection component 63 produces a stable injection effect; wherein, the external water source pump and the dry air pump both use a pressurized method to deliver fluid into the buffer cavity 61 to maintain the fluid pressure in the buffer cavity 61.

[0117] In some embodiments, multiple branch pipes 65 are fixedly connected at intervals to the extended ends of the main pipe 64. A spray hole 66 is defined below the branch pipes 65, connecting the inside and outside of the branch pipes 65. The spray holes 66 on the multiple branch pipes 65 form a spray area that is no smaller than the inner circumference of the bag frame 49, ensuring an effective spray area for the optical glass within. The spray holes 66 can be formed in a block, with mounting notches on the branch pipes 65 for mounting the block.

[0118] In some embodiments, the jet hole 66 has a flat rectangular cross-section, and the rectangular cross-section of the jet hole outlet 67 is smaller than the rectangular cross-section of the jet hole inlet 68. That is, the height of the jet hole inlet 68 is greater than the height of the jet hole outlet 67, resulting in a certain pressure increase effect. However, it should be noted that the pressure increase here and the pressure increase for the buffer cavity 61 described above must not cause impact damage to the optical glass. To increase the injection surface area on the left and right sides of the jet hole outlet, the width of the jet hole outlet 67 is greater than the width of the jet hole inlet. That is, the two side walls of the jet hole inlet 68 and the two side walls of the jet hole outlet are connected by outwardly inclined flared bevels 69.

[0119] In some embodiments, there are two rows of spray holes 66 below a single branch pipe 65, one row of spray holes 66 sprays toward the lower left area of ​​the branch pipe 65, and the other row of spray holes 66 sprays toward the lower right area of ​​the branch pipe 65, that is, the two rows of spray holes 66 are arranged at an angle, which is beneficial to enhancing the effectiveness of spraying on the optical glass surface; the ends of the spraying areas generated by adjacent spray holes 66 in each row of spray holes 66 overlap, so that the fluid sprayed therefrom produces a continuous curtain shape, thereby enhancing the spraying ability on the optical glass surface.

[0120] In some embodiments, the center of the bottom of the buffer cavity 61 is slightly raised, and the connection position between the branch pipe 65 and the buffer cavity 61 is located on the periphery of the bottom of the buffer cavity 61 to better discharge the fluid in the buffer cavity 61.

[0121] The optical glass ultrasonic cleaning method based on the above cleaning device includes the following steps:

[0122] S1. The lifting frame 4 rises to the initial position, that is, the lifting driver 7 drives the lifting frame 4 to rise to the highest position. The loading assembly 5 is at a height of about 1 meter, which is convenient for taking and placing the loading assembly 5. At this time, the water guide plate 6 is above the drainage assembly 13, and the loading mesh bag 38 is separated from the cleaning liquid in the cleaning cabinet 1.

[0123] S2. Place the optical glass to be cleaned vertically in the loading mesh bag 38, and then place the loading mesh bag 38 and the optical glass to be cleaned therein into each small loading space 37. Optical glasses of different sizes can be placed here to adapt to the simultaneous cleaning of optical glasses of multiple specifications. That is, optical glasses of the same specifications can be placed in the corresponding partition 55 positions in the loading mesh bag 38 to avoid the phenomenon of optical glass confusion and facilitate the regular removal of optical glasses later. The setting of the partition 55 can constrain the optical glass to be roughly vertical in the loading mesh bag 38.

[0124] S3, the lifting driver 7 drives the lifting frame 4 to descend. During the descending process, the pusher 24 at the lower end of the lifting frame 4 first contacts the follower block 20 in the drainage assembly 13. Specifically, the pusher 24 contacts the first inclined surface 28 and gradually generates an outward thrust toward the follower block 20, so that the end surface of the drainage plate 18 and the end surface of the water diversion plate 6 gradually move from the overlapping trajectory after the top-down projection toward the gap formation trajectory. When the pusher 24 is at the intersection of the first inclined surface 28 and the top vertical surface 30, the end surface of the drainage plate 18 and the water diversion plate 6 are at the intersection of the first inclined surface 28 and the top vertical surface 30. The end faces are completely staggered, that is, the drain plate 18 will not cause friction with the downward movement of the water guide plate 6; when the pusher 24 moves to the lower end of the top vertical surface 30, the water guide plate 6 drops to the bottom of the drain plate 18, and then through the cooperation of the pusher 24 and the second inclined surface 29, that is, under the action of the reset spring 19, the drain plate 18 is gradually and slowly reset toward the inside, and the drain plate 18 is above the water guide plate 6, so that the drain plate 18 can form a position change for the lifting of the lifting frame 4 through the cooperation between the pusher 24 and the follower block 20. Among them, when the water guide plate 6 is below the drainage assembly 13 and the lifting frame 4 is lowered into place, the optical glass in the loading mesh bag 38 is immersed in the cleaning liquid in the cleaning cabinet 1. In such a case Figure 1 In the front-to-back direction of the drawing, there is a certain distance between the water guide plate 6 and the inner wall of the cleaning cabinet 1. That is to say, during the rising and falling process of the water guide plate 6, it will not be affected by the rising and falling of the cleaning liquid stored in the cleaning cabinet 1.

[0125] S4. According to the cleaning requirements of the optical glass, set the ultrasonic cleaning parameters and duration, start the ultrasonic equipment to make the ultrasonic vibration plate generate ultrasonic waves in the cleaning space, clean the optical glass to be cleaned, and make the surface of the optical glass clean.

[0126] S5. After cleaning is completed, the lifting frame 4 is driven to rise to the initial position by the lifting driver 7. During the rising process of the lifting frame 4, the pushing member 24 cooperates with the second inclined surface 29, the top vertical surface 30, and the first inclined surface 28 in sequence, so that the water guide plate 6 rises to above the drainage component 13; during this rising process, the rising speed of the lifting frame 4 is lower than the previous falling speed of the lifting frame 4, one is to ensure the smoothness of the rise, and the other is to extend the time between the separation of the loading mesh bag 38 from the cleaning liquid and the switching of the water guide plate 6 to the top of the drainage plate 18 as much as possible, so that the cleaning liquid carried by the rising loading mesh bag 38 falls into the cleaning cabinet 1.

[0127] S6. When the cleaned optical glass needs to be rinsed, the lifting spray assembly 14 can be lowered, that is, the lower part of the buffer container 56 is lowered into the carrier 47, so that a spray assembly 63 corresponds to the top of a small loading space 37. By switching the valve, the water source pump is switched to form a connection with the buffer cavity 61, and clean water can be injected into the buffer space. The optical glass is rinsed by the spray of the spray assembly 63. The clean water flowing down during the rinsing process flows into the water collection box 12 through the cooperation of the water guide plate 6 and the drainage plate 18. The water in the water collection box 12 can also be filtered by the filter and pumped by the water source pump. Due to the design of the spray hole structure and the optical glass placed between the adjacent spray holes on the adjacent branch pipes 65, the fluid discharged from the spray hole can be sprayed toward the surface of the optical glass.

[0128] S7. After the flushing is completed, the switching valve is switched to connect the drying air pump with the buffer cavity 61, and the drying air is delivered to the buffer cavity 61 in the lifting spray assembly 14 by the drying air pump to dry the optical glass and accelerate the drying of the optical glass. After the air supply and drying time is over, the lifting spray assembly 14 is lifted and reset by the lifting drive structure 57. After reset, the distance between the lower end of the lifting spray assembly 14 and the upper end of the loading assembly 5 is greater than the height of the loading assembly 5 itself, so as to facilitate the loading of the net bag 38 and the entire loading assembly 5.

[0129] S8. Take out the loading mesh bag 38 together with the optical glass therein from the loading assembly 5. After taking out, sort the optical glass in the loading mesh bag 38.

[0130] During step S5 , after the loading mesh bag 38 and the water guide plate 6 are separated from the cleaning liquid, and when the water guide plate 6 is below the drainage assembly 13 , the lifting frame 4 can be designed to stay for 20-40 seconds to allow the cleaning liquid to drip into the cleaning cabinet 1 .
