Description

Technical Field

[0001] This invention relates to an ultrasonic cleaning apparatus and method for optical glass. Background Technology

[0002] The cleaning of optical glass is mostly carried out using ultrasound. Ultrasonic waves create cavitation, acceleration, and direct flow within the cleaning solution, dispersing, emulsifying, and peeling off the contaminant layer on the optical glass surface to achieve the cleaning purpose. Most ultrasonic cleaning devices for optical glass use independent ultrasonic cleaning tanks. After ultrasonic cleaning, the glass is moved laterally to the rinsing station. After rinsing, it is then moved laterally to the drying equipment. The entire cleaning device occupies a large lateral space, and optical glass is often left stationary during ultrasonic cleaning, requiring a considerable amount of time to achieve the desired cleaning effect. Therefore, based on current cleaning devices, further research and development are needed on the structure and operation of these devices. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this invention is to provide an ultrasonic cleaning device and method for optical glass that integrates multiple functions, occupies little horizontal space, and is easy to promote and use.

[0004] The technical solution for implementing the present invention is as follows:

[0005] An ultrasonic cleaning device for optical glass includes a cleaning cabinet, the interior of which is a cleaning space, and ultrasonic vibration plates are arranged around the perimeter of the cleaning cabinet.

A loading component for loading optical glass is installed in the middle of the lifting frame. A water guide plate is installed at the bottom of the lifting frame below the loading component to collect the water dripping from the loading component. The water guide plate directs the water on it to both ends. A lifting drive is installed on the back of the lifting cabinet to drive the lifting frame to move up and down.

[0024] The vertical length of the top vertical surface is greater than the end height of the water inlet plate.

[0025] In one embodiment of this application, the loading assembly includes a bearing plate, a positioning plate, and a loading plate, all arranged horizontally.

[0026] The side of the support plate is fixedly connected to the middle of the lifting frame, and the positioning plate is clamped onto the support plate;

[0027] The loading plate is rotatably mounted on the positioning plate, and a drive mechanism is provided on the positioning plate to drive the loading plate to reciprocate within a rotation angle of no more than 30 degrees on the positioning plate;

[0028] The loading platform has multiple small loading spaces;

[0032] The positioning plate has a circular positioning opening inside;

[0033] The outer periphery of the loading plate is circular and adapted to the positioning port. The upper part of the outer periphery of the loading plate is an annular locking part that is locked onto the upper surface of the positioning plate, and the lower part of the outer periphery is an annular inserting part that is inserted into the positioning port.

[0034] The drive mechanism includes a driven member located on the upper outer periphery of the loading plate and an active member installed on the upper corner of the positioning plate. The active member drives the driven member to rotate around the center of the positioning port on the positioning plate.

[0035] In one embodiment of this application, the loading plate contains a large circular loading space;

[0036] A ring-shaped support structure is set in the center of the large loading space;

[0037] The outer periphery of the carrier body has multiple bearing support plates. The outer ends of the bearing support plates are fixed to the inner periphery of the loading plate, and the inner ends are fixed to the outer periphery of the carrier body.

[0038] Multiple load-bearing plates are arranged in a ring in the annular space formed between the inner periphery of the loading plate and the outer periphery of the load-bearing body, and adjacent load-bearing plates constitute the aforementioned small loading space.

[0039] The loading mesh bag includes a U-shaped bag frame and a mesh bag body mounted on the bag frame;

[0040] The two sides of the bag frame are respectively secured to the upper surface of the adjacent load-bearing support plate;

[0041] Lifting handles are fixedly installed on both sides of the bag frame.

[0042] In one embodiment of this application, the lifting spray assembly includes a buffer container and a lifting drive structure;

[0043] The lifting drive structure is assembled on the lifting frame. The drive end of the lifting drive structure is connected to the buffer container, which drives the buffer container to move up and down directly above the loading component.

[0044] The buffer container has a circular outer circumference and a closed buffer cavity on the inner circumference;

[0045] Multiple spraying components are fixedly connected in a ring around the outer periphery of the buffer container, forming a communication with the buffer cavity. Each spraying component corresponds to a small loading space.

[0046] The injection assembly includes a main pipe and multiple branch pipes. One end of the main pipe is connected to the buffer cavity, and the other end extends radially outward along the buffer container.

The spraying area formed by the through holes on the multiple branch pipes is not less than the inner circumferential area of ​​the bag frame.

[0048] An ultrasonic cleaning method for optical glass includes the following steps.

[0049] S1. The lifting frame rises to the initial position, and the water inlet plate is above the water inlet assembly;

[0050] S2. Place the optical glass to be cleaned into the loading mesh bag, and then place the loading mesh bag and the optical glass to be cleaned into the small loading space.

[0051] S3. The lifting frame descends, and the water-guiding plate is positioned below the water-guiding component, allowing the optical glass in the loaded mesh bag to be immersed in the cleaning solution inside the cleaning cabinet.

[0052] S4. Start the ultrasonic equipment to generate ultrasonic waves in the cleaning space using the ultrasonic vibrating plate to clean the optical glass to be cleaned.

[0053] S5. After cleaning, the lifting frame rises to the initial position, so that the water diversion plate is above the diversion assembly.

[0054] S6. The lifting spray assembly descends and delivers clean water into the lifting spray assembly to spray and clean the ultrasonically cleaned optical glass in the loaded mesh bag. The sprayed water flows into the water collection tank through the water guide plate and the diversion assembly.

[0057] During step S5, the loading net bag and the water guide plate are removed from the cleaning fluid, and the lifting frame stays for 20-40 seconds when the water guide plate is below the drainage component.

[0058] The beneficial effects of this invention are:

[0059] 1. This cleaning device integrates ultrasonic cleaning of optical glass, post-cleaning rinsing of optical glass, and drying into a single vertical structure. The working space can be switched within the cleaning device as needed, reducing the space occupied by the cleaning device.

[0060] 2. The load-bearing plate, positioning plate, and loading plate in the loading assembly are stacked together to form an assembly, which facilitates assembly, disassembly, and maintenance.

[0084] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0085] Please see Figure 1 As shown in Figure 13, an ultrasonic cleaning device for optical glass is used to clean the surface of optical glass. It includes a cleaning cabinet 1, the interior of which is a cleaning space for holding optical glass cleaning fluid. Ultrasonic vibrating plates 2 are arranged around the perimeter of the cleaning cabinet 1 for connection to an external ultrasonic generator to generate ultrasonic waves within the cleaning space to clean the surface of the optical glass. The connection and arrangement of the ultrasonic vibrating plates and ultrasonic generator can adopt existing ultrasonic cleaning structures, as long as ultrasonic cleaning can be generated within the cleaning cabinet.

[0086] A lifting cabinet 3 is installed above the cleaning cabinet 1. The lifting cabinet 3 covers the cleaning cabinet 1. A lifting frame 4 is installed inside the lifting cabinet 3. When a vertical upward or downward external force is applied from above the lifting cabinet 3 to the lifting frame 4, the lifting frame 4 can move upward or downward inside the lifting cabinet 3.

[0087] A loading assembly 5 for loading optical glass is set in the middle of the lifting frame 4. The loading assembly 5 rises and falls with the lifting frame 4. A water guide plate 6 for collecting water dripping from the loading assembly 5 is set at the bottom of the lifting frame below the loading assembly 5. The water guide plate 6 is generally flat U-shaped. The two sides of the water guide plate 6 are baffles higher than the middle to prevent water from flowing out from both sides. The bottom wall of the water guide plate 6 gradually slopes downward from its middle line towards both ends so that the water on it can be guided to both ends through the bottom wall of the water guide plate 6, thereby accelerating the speed at which water flows out of the water guide plate 6.

[0088] A lifting drive 7, which drives the lifting frame 4 to move up and down, is installed on the back of the lifting cabinet 3. The driving end of the lifting drive 7 is connected to the top of the lifting frame 4 through a connecting frame 8 passing through the back of the lifting cabinet 3. The lifting drive 7 uses a telescopic hydraulic cylinder. A clearance slot 9 is provided on the upper part of the back of the lifting cabinet 3 to accommodate the connecting frame 8. A protective cover is installed on the back of the lifting cabinet 3 to enclose the lifting drive 7, thereby increasing its protective capability. Furthermore, placing the lifting drive 7 on the back of the lifting cabinet reduces the vertical space occupied by the cleaning device.

[0089] Vertical guide plates 10 are fixedly installed on the inner walls of both sides of the lifting cabinet 3, and guide wheels 11 are installed on the outer side of the lifting frame 4. The vertical guide plates 10 have guide grooves on their sides for the guide wheels 11 to be inserted and arranged vertically. The guide wheels 11 move within the vertical guide plates 10 to enhance the stability of the lifting frame 4 in vertical rising and falling.

[0090] The cleaning cabinet 1 has water collection tanks 12 on both sides for the water to flow into the water from the water guide plate 6. The upper part of the two water collection tanks is fixedly equipped with diversion components 13 that connect with the two ends of the water guide plate 6. The water on the water guide plate 6 is introduced into the water collection tank 12 through the diversion components 13. The cooperation between the water guide plate 6 and the diversion components 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 tank 12 through the water guide plate 6 and the diversion components 13.

[0091] A lifting spray assembly 14 is disposed on the upper part 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 move up and down within the lifting frame 4. That is, when picking up or putting down materials, the lifting spray assembly 14 rises to a high position within the lifting frame 4 without affecting the picking up or putting down of materials. 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, and then washes and blows the optical glass.

[0092] The drainage assembly 13 includes a base plate 15, a movable support block 16, a fixed support block 17, a drainage plate 18, a return spring 19, and a follower block 20. The base plate 15 is fixedly installed in the upper part of the water collection tank 12 near the cleaning cabinet 1 by bolts or welding. The entire base plate 15 is arranged horizontally, and an installation support surface is formed on the upper surface of the base plate 15. The movable support block 16 is slidably installed on the upper surface of the base plate 15 in the horizontal direction. A slide rail 21 is installed on the left and right sides of the upper surface of the base plate 15. The movable support block 16 is slidably installed on the slide rail 21 and can slide closer to or away from the cleaning 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 closer to the water collection tank 12, and the movable support block 16 is closer to the cleaning cabinet 1, moving closer to or away from the upper end of the cleaning 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 both. A guide post 22 is fixed on the side of the fixed support block 17 facing the movable support block 16. A vertical plate 23 is fixedly mounted on the outer side of the upper end of the movable support block 16. The guide post 22 passes through the vertical plate 23. The return spring 19 is sleeved on the guide post 22. The outer end of the return spring 19 abuts against the side of the fixed support block 17 and the inner end abuts against the side of the movable support block 16. Thus, 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 mounted on the movable support block 16 on the side near the cleaning cabinet 1; the diversion plate 18 is fixedly mounted on the movable support block 16 and moves together with the movable support block 16. The diversion plate 18 adopts an inclined design with the outer end lower than the inner end, so as to facilitate diversion towards the water collection tank 12. The outer end of the diversion plate 18 extends outward and is lower than the upper opening of the water collection tank 12, so as to ensure that the water on the diversion plate 18 can flow into the water collection tank 12.

[0095] The width of the diversion plate 18 near the end of the water diversion plate 6 is at least greater than the end width of the water diversion plate 6. The water diversion plate 6 is equipped with a pusher 24 that generates an outward pushing force on the follower block 20 when it comes into contact with the follower block 20, thereby compressing and storing the return spring 19. The pusher 24 is a push wheel or push wedge mounted on the outer side of the water diversion plate 6 via the mounting bracket 70. The outer circumference of the push wheel extends beyond the outer end face of the water diversion plate 6, ensuring that the pusher 24 can form an effective engagement relationship with the follower block 20.

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

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

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

[0099] In some embodiments, the follower block 20 has an isosceles trapezoidal follower portion 27 on the side near the cleaning cabinet 1. The isosceles trapezoidal follower portion 27 is arranged on one side of the follower block 20 after being rotated 90 degrees clockwise. 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 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 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. The bottom vertical surface 31 is fixedly disposed with the side of the follower block 20. The follower 27 and the follower block 20 can be connected by a detachable fixed connection to facilitate the periodic maintenance and replacement of the follower 27.

[0100] In some embodiments, when the diversion plate 18 is in the reset state, after projection from top to bottom, the distance D1 between the frontmost surface of the diversion plate 18 and the outermost surface of the water diversion 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 diversion plate 6. When the pusher 24 descends and contacts the first inclined surface 28, there is a certain distance between the water diversion plate 6 and the diversion plate 18 in the vertical direction, so no collision will occur. When the pusher 24 continues to descend and contacts the top vertical surface 30, the pusher 24 will push the follower 27 backward. After projection from top to bottom, there is a gap between the end face of the water diversion plate 6 and the end face of the diversion plate 18, so that the water diversion plate 6 can move down smoothly without obstruction. When the pusher 24 descends and contacts the second inclined surface 29, the diversion plate 18 The device is already above the water guide plate 6, and will not collide with the water guide plate 6 during subsequent resetting. Thus, through the cooperation of the pusher 24 and the follower 27, it can be ensured that the water guide plate 6 will not collide with the diversion plate 18 during the up and down movement. When the lifting frame rises to the rinsing position, the pusher 24 is disengaged from the first inclined surface 28. At this time, there is a certain overlap between the projection of the end of the diversion plate 18 and the end of the water guide plate 6, so that the water on the water guide plate 6 can flow onto the diversion plate 18.

[0101] In some embodiments, when the pusher 24 is not in contact with the first inclined surface 28 / second inclined surface 29, the projection from top to bottom or bottom to top still shows a partial overlap between the pusher 24 and the first inclined surface 28 / second inclined surface 29. This allows the pusher 24 to smoothly contact the follower 27 and generate an effective backward thrust on the follower 27. The inclination angle of the first inclined surface 28 / second inclined surface 29 is approximately 30 degrees. This avoids excessively large angles that could affect the collision force between the pusher 24 and the follower 27, causing mutual damage. It also avoids the need for longer inclined surfaces for transition due to smaller angles, and prevents reduced sensitivity in the cooperation between the follower 27 and the pusher 24.

[0102] In some embodiments, the loading assembly 5 includes a support plate 32, a positioning plate 33, and a loading plate 34, all arranged horizontally. The side of the support plate 32 is fixedly connected to the middle of the lifting frame 4. Connecting blocks 35 are fixed to at least two outer sides of the middle of the support plate 32. The connecting blocks 35 are bolted to the connecting seats 36 in the lifting frame 4. The positioning plate 33 is snapped onto the support plate 32, making it convenient for the positioning plate 33 to be loaded and unloaded from the support plate 32.

[0103] The loading plate 34 is rotatably mounted on the positioning plate 33, meaning 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 rotation angle of no more than 30 degrees. During ultrasonic cleaning, the drive mechanism can cause the loading plate 34 to rotate slowly at a small angle, resulting in a slight positional change of the optical glass in the ultrasonic cleaning fluid. This allows for better ultrasonic cleaning of the optical glass surface, increasing cleaning efficiency and effectiveness. The reciprocating rotation frequency and speed of the loading plate must not impact the rotation of the optical glass; the rotation only needs to cause a change in the position of the optical glass.

[0104] The loading plate 34 has multiple small loading spaces 37. Loading mesh bags 38 for placing optical glass are suspended on the loading plate 34 in each small loading space 37. The loading mesh bags 38 extend downward toward the loading assembly 5, so that during the ultrasonic cleaning process, the optical glass in the loading mesh bags 38 can be immersed below the liquid surface and effectively cleaned by ultrasonic waves.

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

[0106] The positioning plate 33 has a circular positioning opening 42 in the middle that runs through the upper and lower surfaces; the outer periphery of the loading plate 34 is circular and conforms to the positioning opening 42. The upper part of the outer periphery of the loading plate 34 is an annular locking part 43 that is locked onto the upper surface of the positioning plate 33, and the lower part of the outer periphery is an annular insert part 44 that is inserted into the positioning opening. Thus, when the loading plate 34 is placed into the positioning opening 42, the loading plate 34 has a space to rotate around the center of the positioning opening; that is, the lower outer end face of the annular locking part 43 slides with the upper surface of the positioning opening 42, and the outer peripheral wall of the annular insert part 44 slides with the inner peripheral wall of the positioning opening 42.

[0107] The drive mechanism includes a driven member 45 disposed on the upper outer periphery of the loading plate 34 and an active member 46 mounted on the corner of the upper surface of the positioning plate 33. The active member 46 drives the driven member 45 to move, so that the loading plate 34 rotates on the positioning plate 33 with the center of the positioning port as the center.

[0108] In implementation, the drive mechanism can be implemented using a gear and rack system. For example, the driven member 45 is an arc-shaped rack mounted on the outer periphery of the loading plate 34, and the driving member 46 is a gear mounted on the positioning plate 33. The gear is driven by a motor, thereby enabling the drive mechanism to rotate the loading plate 34 on the positioning plate 33. Alternatively, a telescopic cylinder can be used. 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 periphery of the loading plate 34. The telescopic end of the telescopic cylinder is movably connected to the driven block. The telescopic cylinder's extension and retraction along the tangential direction of the outer periphery of the loading plate 34 drives the rotation of the loading plate 34 on the positioning plate 33. Thus, during ultrasonic cleaning, the drive mechanism can drive the loading plate to reciprocate at a certain angle on the positioning plate, thereby causing the optical glass to move in the cleaning fluid and increasing cleaning efficiency.

[0109] In some embodiments, the loading plate 34 contains a large circular loading space. A ring-shaped support 47 is positioned at the center of this large loading space. The support 47 and the loading plate 32 share a common center. Multiple support plates 48 are located around the outer periphery of the support 47. The outer ends of the support plates 48 are fixed to the inner periphery of the loading plate 34, and their inner ends are fixed to the outer periphery of the support 47. These multiple support plates 48 are arranged in a ring within the annular space formed between the inner periphery of the loading plate 34 and the outer periphery of the support 47, thus creating the aforementioned small loading spaces 37 between adjacent support plates 48. Through the arrangement of the multiple support plates 48, the large loading space is divided into multiple small loading spaces 37, and the optical glass is placed within each of these small loading spaces 37.

[0110] In some embodiments, the support plate 48 is arranged horizontally, with its upper surface serving as the support surface. The loading net bag 38 includes a U-shaped bag frame 49 and a net bag body 50 mounted on the bag frame 49. The net bag body 50 can be made of rigid net bag, such as a stainless steel wire 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 engaged with the upper surfaces of adjacent support plates 48 to suspend the loading net bag 38 between adjacent 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. The opening of the net bag body 50 is fixed to the bag frame 49. Lifting handles 54 are fixedly provided on both sides of the bag frame 49 to facilitate the loading net bag 38 being taken out 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 divide the space within the mesh bag body 50 for placing different types of optical glass. This allows for the mixing and washing of different types of optical glass without causing confusion. In practice, the partition 55 can be made of stainless steel wire mesh. The partition 55 can extend downwards to a certain length, providing a corresponding vertical constraint on the optical glass.

[0112] In some embodiments, the lifting spray assembly 14 includes a buffer container 56 and a lifting drive structure 57; a support plate 58 is fixedly installed above the lifting frame 4, and the lifting drive structure 57 is vertically mounted on the support plate. The lifting drive structure 57 is a telescopic cylinder, such as a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0113] The driving end of the lifting drive structure 57 is connected to the buffer container 56, causing the buffer container 56 to move up and down 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, and 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 lifting of the base plate 59 and the buffer container 56. When rinsing is required, the lifting drive structure 57 drives the base plate 59 to descend, allowing the buffer container 56 to descend into place. When rinsing is not required, the lifting drive structure 57 drives the base plate 59 to rise and reset.

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

[0115] In some embodiments, a plurality of spraying assemblies 63, communicating with the buffer cavity 61, are fixedly connected in a ring around the outer periphery of the buffer container 56. Each spraying assembly 63 corresponds to a small loading space 37, and is responsible for spraying optical glass in the small loading space 37. The spraying assembly 63 includes a main pipe 64 and a plurality of 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 for easy assembly and disassembly. 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 delivered to each branch pipe 65 through the main pipe 64. By arranging the buffer cavity 61 and the main pipe 64 in a ring around the outer periphery of the buffer cavity 61, the fluid in the buffer cavity 61 can enter the main pipe 64 evenly, improving the uniformity of the spray flow of each spraying assembly 63.

[0116] In some embodiments, the volume of the buffer space is at least twice or more than twice the volume of all the spray components 63, so as to ensure that there is sufficient fluid in the buffer space and that the corresponding pressure can be generated toward the spray components 63, so that the spray components 63 can produce a stable spraying effect; wherein, the external water pump and the dry air pump are pressurized to send fluid into the buffer cavity 61 to maintain the fluid pressure in the buffer cavity 61.

[0117] In some embodiments, a plurality of branch pipes 65 are fixedly connected at intervals to the extension end of the main pipe 64. A jetting through-hole 66 communicating with the inside and outside of each branch pipe 65 is provided below the branch pipe 65. The jetting area formed by the jetting through-holes 66 on the plurality of branch pipes 65 is not smaller than the inner circumferential area of ​​the bag frame 49, to ensure an effective jetting area is formed on the optical glass within the bag frame. The jetting through-hole 66 may be formed in a block, and the branch pipe 65 has a mounting slot for assembling the block.

[0118] In some embodiments, the jetting orifice 66 adopts a flat rectangular cross-section. The rectangular cross-section of the jetting orifice outlet 67 is smaller than the rectangular cross-section of the jetting orifice inlet 68, that is, the height of the jetting orifice inlet 68 is greater than the height of the jetting orifice outlet 67, thereby generating a certain pressure boosting effect. However, it should be noted that the pressure boosting here and the aforementioned pressure boosting of the buffer cavity 61 must not cause impact damage to the optical glass. In order to increase the jetting surface on the left and right sides of the jetting orifice outlet, the width of the jetting orifice outlet 67 is greater than the width of the jetting orifice inlet, that is, the two side walls of the jetting orifice inlet 68 and the two side walls of the jetting orifice outlet are connected by flared inclined surfaces 69 that are inclined outwards.

[0119] In some embodiments, a single branch pipe 65 has two rows of jet holes 66 below it. One row of jet holes 66 jets towards the lower left region of the branch pipe 65, and the other row of jet holes 66 jets towards the lower right region of the branch pipe 65. That is, the two rows of jet holes 66 are arranged at an angle, which helps to enhance the effectiveness of jetting onto the optical glass surface. The ends of the jetting areas generated by adjacent jet holes 66 in each row of jet holes 66 overlap, so that the jetted fluid produces a continuous curtain shape, which enhances the jetting capability onto the optical glass surface.

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

[0121] The ultrasonic cleaning method for optical glass based on the above-mentioned 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 component 5 is about 1 meter high, which is convenient for loading component 5 to be picked up and put down. At this time, the water guide plate 6 is above the diversion component 13, and the loading net bag 38 is removed 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 in each small loading space 37. Here, the glass can be placed according to the size of different optical glass to accommodate the simultaneous cleaning of multiple specifications of optical glass. That is, optical glass of the same specification can be placed in the corresponding partition 55 position in the loading mesh bag 38 to avoid the phenomenon of optical glass being disordered and to facilitate the orderly removal of optical glass in the future. 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 descent, the pusher 24 at the lower end of the lifting frame 4 first contacts the follower block 20 in the diversion assembly 13. Specifically, the pusher 24 contacts the first inclined surface 28 and gradually generates an outward pushing force toward the follower block 20, causing the end face of the diversion plate 18 and the end face of the water diversion plate 6 to gradually move along the trajectory of the overlap after projection from top to bottom toward the formation of the gap. When the pusher 24 is at the intersection of the first inclined surface 28 and the top vertical surface 30, the end face of the diversion plate 18 and the water diversion plate 6... The end faces are completely offset, meaning the diversion plate 18 will not rub against the downward movement of the water diversion plate 6. When the pusher 24 reaches the lower end of the top vertical surface 30, the water diversion plate 6 descends below the diversion plate 18. Then, through the cooperation of the pusher 24 and the second inclined surface 29, i.e., under the action of the return spring 19, the diversion plate 18 is gradually and slowly reset inward, with the diversion plate 18 positioned above the water diversion plate 6. Thus, the diversion plate 18 can change the position of the lifting frame 4 through the cooperation between the pusher 24 and the follower block 20. When the water diversion plate 6 is below the diversion assembly 13 and the lifting frame 4 has descended to its final position, the optical glass in the loading mesh bag 38 is immersed in the cleaning fluid inside the cleaning cabinet 1. Figure 1 In the front-back direction of the view, 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 of the water guide plate 6, it will not be affected by the mutual rising and falling because the cleaning liquid is stored in the cleaning cabinet 1.

[0125] S4. According to the cleaning requirements of optical glass, set the ultrasonic cleaning parameters and duration, start the ultrasonic equipment to 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, the lifting frame 4 is raised to the initial position by the lifting driver 7. During the raising of the lifting frame 4, the pusher 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 above the diversion assembly 13. During this raising process, the raising speed of the lifting frame 4 is less than the lowering speed of the lifting frame 4 beforehand. This is to ensure the stability of the raising and to extend the time between the loading net bag 38 leaving the cleaning fluid and the water guide plate 6 switching to the diversion plate 18, so that the cleaning fluid carried by the loading net 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 so that the lower part of the buffer container 56 is lowered into the carrier 47, so that one spray assembly 63 corresponds to the upper part of a small loading space 37. By switching the valve, the water source pump is connected to 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 tank 12 through the cooperation of the water guide plate 6 and the diversion plate 18. The water in the water collection tank 12 can also be filtered by the filter and pumped by the water source pump. Due to the design of the spray through-hole structure, and the fact that the placed optical glass is located between the close spray through-holes on the adjacent branch pipes 65, the fluid discharged from the spray through-hole can be sprayed toward the surface of the optical glass.

[0128] S7. After rinsing, the switching valve connects the drying air pump to the buffer cavity 61. The drying air pump delivers drying gas to the buffer cavity 61 in the lifting spray assembly 14 to dry the optical glass and accelerate the drying process. After the drying time is over, the lifting spray assembly 14 is raised and reset by the lifting drive structure 57. After reset, the distance between the bottom of the lifting spray assembly 14 and the top 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 loading assembly 5.

[0129] S8. Take the loading net bag 38, along with the optical glass inside, out of the loading assembly 5. After taking it out, sort the optical glass in the loading net bag 38.

[0130] During step S5, after the loading net bag 38 and the water guide plate 6 are removed from the cleaning fluid, and when the water guide plate 6 is below the diversion component 13, the lifting frame 4 can be designed to stay for 20-40 seconds so that the cleaning fluid drips into the cleaning cabinet 1.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
