Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology for optical lenses, and more specifically to an ultrasonic cleaning machine for optical lenses. Background Technology

[0002] An ultrasonic cleaning machine for optical lenses is a specialized device that utilizes the cavitation effect of ultrasound to perform high-cleanliness cleaning on various precision optical components such as camera lenses, telescope and microscope lenses, spectacle lenses, and other optical glass.

[0003] In traditional ultrasonic cleaning machines for optical lenses, the lenses are placed in a cleaning solution within a cleaning tank, where ultrasonic waves remove contaminants. After cleaning, the ultrasonic generator must be turned off, and the cleaned lenses are removed. Gravity then allows suspended impurities in the cleaning solution to settle naturally to the bottom of the tank or into a collection area. This passive settling process is time-consuming, reducing equipment turnover efficiency and potentially causing secondary contamination of the lenses due to prolonged suspension of impurities.

[0004] To address the aforementioned issues, there is an urgent need to develop an ultrasonic cleaning machine for optical lenses. Its core feature is an active impurity collection structure that can collect suspended impurities in the cleaning solution in real time and efficiently after the cleaning process is completed, without relying on natural sedimentation. This significantly shortens the post-processing time and improves cleaning efficiency and cleanliness reliability. Summary of the Invention

[0005] In response to the problems raised in the background art, the present invention provides an ultrasonic cleaning machine for optical lenses, which will be further described below.

[0006] An ultrasonic cleaning machine for optical lenses includes a cleaning machine frame, which is a semi-enclosed frame structure. Two vertically symmetrically arranged lead screws are connected to the cleaning machine frame, each with a drive wheel at its top. A belt is wound between the two drive wheels. A motor is mounted on the outer wall of the cleaning machine frame, and an ultrasonic generator is mounted on the frame. The output shaft of the motor is keyed to one of the lead screws. A lifting frame is threadedly connected between the two lead screws. A support is located in the middle of the lifting frame. Two symmetrically distributed support frames slide within the inner cavity of the cleaning machine frame, and a placement frame is fixedly connected between the two support frames. The bottom of the placement frame contacts the top of the support. The placement frame has a structure for supporting optical lenses. An active impurity collection structure is located at the bottom of the lifting frame, directly below the placement frame.

[0007] Preferably, the active impurity collection structure includes a storage box that is laterally embedded and slidably connected to the bottom of the lifting frame. The storage box is a box structure with an open top and an open bottom. A connecting frame is fixed to the lifting frame, and two symmetrically arranged rotating shafts are rotated on the connecting frame. An armored conveyor belt is wound between the two rotating shafts. A gap is left between the armored conveyor belt and the inner wall of the cleaning machine frame. The armored conveyor belt is in close contact with the top of the storage box. A gear is keyed to the end of one of the rotating shafts. A vertically arranged rack is fixed to the inner cavity of the cleaning machine frame, and the rack is located above the gear.

[0008] Preferably, the armored conveyor belt has multiple evenly distributed grooves that are wider at the bottom and narrower at the top.

[0009] Preferably, the storage box is fixedly connected to the left and right side walls with support columns, and the cleaning machine frame is provided with irregular guide grooves on the left and right side walls. The support columns are slidably embedded in the corresponding guide grooves, and a connecting plate is provided on the outer side of the top of the guide groove.

[0010] Preferably, the side wall of the connecting frame is fixed with two symmetrically distributed fixed seats, each fixed seat is hinged with a lever, and a limiting plate is slidably connected between the two fixed seats. The bottom of the limiting plate is attached to the top left area of ​​the armored conveyor belt, and the top of the limiting plate is fixed with two symmetrically arranged T-shaped frames. Each T-shaped frame has a transverse groove, and the free end of the lever is embedded and slidably connected in the corresponding transverse groove. The inner cavity side wall of the cleaning machine frame is fixed with extrusion columns that correspond one-to-one with the levers.

[0011] Preferably, the top of the storage box is provided with multiple cleaning blocks, which are slidably embedded in the grooves on the armored conveyor belt.

[0012] Preferably, a synchronous shaft is transferred to the connecting frame, and the synchronous shaft and the rotating shaft are connected by a synchronous belt drive. An eccentric wheel is keyed to one end of the synchronous shaft. A striking plate located on the back of the armored conveyor belt is slidably connected to the connecting frame. A transmission frame is fixed to the striking plate. A slot is opened on the transmission frame, and the slot of the transmission frame and the working end of the eccentric wheel are embedded and slidably connected.

[0013] Preferably, the placement structure includes a receiving frame hinged to the placement rack, a plurality of placement units are provided on the top of the receiving frame, a fixing block is fixedly connected to one side of the receiving frame, and a vertically arranged limiting groove is opened at the corresponding position on the inner cavity side wall of the cleaning machine frame. The limiting groove is located above the placement rack, and the fixing block is embedded and slidably fitted in the limiting groove.

[0014] Preferably, the motor is provided with a sealed protective shell.

[0015] Beneficial effects: This device raises the lifting frame, bringing the placement structure and the optical lenses it carries to a height convenient for manual handling. The storage box, connecting frame, and armored conveyor belt rise synchronously, allowing the armored conveyor belt to actively intercept and capture suspended impurities in its upward path. Through gears meshing with a fixed rack, the rotating shaft is driven to rotate, thereby driving the armored conveyor belt to transport the collected impurities along the conveying path and drop them into the storage box below. This achieves coordinated operation of lifting the cleaned lenses and actively collecting impurities. There is no need to wait for the impurities to settle naturally; the device can efficiently capture and centrally collect suspended contaminants in the cleaning solution while the lenses are being removed, significantly shortening the post-processing time.

[0016] By using grooves to accommodate impurities and reduce the possibility of re-suspension due to liquid disturbance, and by using limiting plates to laterally block impurities on the armored conveyor belt to prevent impurities from getting stuck in gaps, the limiting plates are lifted and unrestrained by the squeezing action of squeezing columns and levers, and the cleaning blocks and grooves work together to prevent impurity residue. This achieves efficient collection, safe transport and unloading of impurities, effectively solving the problems of slow impurity settling, easy jamming and difficult cleaning in traditional ultrasonic cleaning machines.

[0017] The eccentric wheel rotates through the linkage of the rotating shaft, synchronous belt, and synchronous shaft. The eccentric motion of the eccentric wheel, through its sliding cooperation with the groove of the transmission frame, causes the transmission frame to move back and forth in a linear motion, thereby driving the striking plate to periodically strike the back of the armored conveyor belt, effectively shaking off impurities that are attached to or stuck in the groove, and further preventing impurity residue.

[0018] By using a fixing block and a limiting groove, one end of the receiving frame is raised, and the whole frame is tilted. This keeps the optical lens it carries in a non-horizontal state during the ultrasonic cleaning process, which helps the attached impurities to fall off more smoothly under the combined action of cavitation effect and gravity, thus improving cleaning efficiency.

Detailed Implementation

[0026] Next, combine Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0027] refer to Figure 1 and Figure 2 and Figure 3 An ultrasonic cleaning machine for optical lenses includes a cleaning machine frame 1, which is a semi-enclosed frame structure. Two vertically symmetrically arranged lead screws 12 are connected to the cleaning machine frame 1. Each lead screw 12 has a drive wheel 16 at its top, and a belt 15 is wound between the two drive wheels 16. A motor 11 is installed on the outer wall of the cleaning machine frame 1. An electrically controlled ultrasonic generator is installed on the cleaning machine frame 1. The output shaft of the motor 11 is keyed to one of the lead screws 12 to drive its rotation. The two lead screws 12 are connected... A common threaded connection is provided with a lifting frame 13, and a support is provided in the middle of the lifting frame 13. Two symmetrically distributed support frames 17 are slidably connected in the inner cavity of the cleaning machine frame 1. A placement frame 14 is fixedly connected between the two support frames 17. The bottom of the placement frame 14 contacts the top of the support, and the support supports the placement frame 14. The placement frame 14 is provided with a placement structure for carrying optical lenses. The bottom of the lifting frame 13 is provided with an active impurity collection structure, which is located directly below the placement frame 14 and is used to actively capture and collect suspended impurities in the cleaning fluid.

[0028] The active impurity collection structure includes a storage box 21 that is horizontally embedded and slidably connected to the bottom of the lifting frame 13. The storage box 21 is a box structure with an open top for temporarily storing the collected impurities. The storage box 21 has an opening at the bottom for draining sewage.

[0029] refer to Figure 4A connecting frame 29 is fixedly connected to the lifting frame 13. Two symmetrically arranged rotating shafts 23 are rotatably connected to the connecting frame 29. An armored conveyor belt 2 is wound between the two rotating shafts 23. The armored conveyor belt 2 has corrosion-resistant and wear-resistant properties. A gap is left between the armored conveyor belt 2 and the inner wall of the cleaning machine frame 1. The armored conveyor belt 2 is close to the top of the storage box 21. Its function is to actively intercept and receive impurities suspended in the cleaning liquid during the rising process. On the other hand, it transports the received impurities to the storage box 21 for centralized collection through its own operation. A gear 24 is keyed to the end of one of the rotating shafts 23. A vertically arranged rack 25 is fixedly connected to the inner cavity of the cleaning machine frame 1. The rack 25 is located above the gear 24.

[0030] In the initial state, the lifting frame 13 is at its lowest position, the placement frame 14 and the placement structure on it are supported by the support, and the storage box 21 is located at the bottom of the inner cavity of the cleaning machine frame 1, directly below the placement structure. At this time, the gear 24 and the rack 25 have not yet meshed.

[0031] During operation, the optical lens to be cleaned is placed in the placement structure, and an appropriate amount of cleaning fluid is injected into the cleaning machine frame 1, with the fluid level slightly higher than the top of the lens. The electrically controlled ultrasonic generator is then activated, utilizing the ultrasonic cavitation effect to complete the cleaning. After cleaning, the ultrasonic generator is turned off. At this point, a large number of fine impurities remain suspended in the cleaning fluid, while a small number of larger impurity particles fall onto the surface of the armored conveyor belt 2.

[0032] At this time, the motor 11 is started, the lead screw 12 rotates forward, driving the lifting frame 13 to move upward, and linking the support frame 17, the placement frame 14 and the placement structure and the optical lens it carries to a height that is convenient for manual handling.

[0033] During the upward movement of the lifting frame 13, the storage box 21, the connecting frame 29, and the armored conveyor belt 2 rise synchronously. The armored conveyor belt 2 actively intercepts and captures suspended impurities in the upward path. When the lifting frame 13 rises to the set height, the gear 24 meshes with the fixed rack 25, and drives the rotating shaft 23 to rotate under the action of relative motion, thereby driving the armored conveyor belt 2 to operate. The impurities that have been received are transported along the conveying path and fall into the storage box 21 below. This achieves the coordinated operation of lifting the cleaned lens and actively collecting the impurities. There is no need to wait for the impurities to settle naturally. The efficient capture and centralized collection of suspended pollutants in the cleaning solution can be completed at the same time as the lens is taken out, which significantly shortens the post-processing time.

[0034] refer to Figure 5To ensure that the impurities removed during the cleaning process can be effectively retained on the armored conveyor belt 2 and transported to the storage box 21 as it rotates, and to prevent the impurities from being resuspended in large quantities due to disturbance during the transport process, the surface of the armored conveyor belt 2 is provided with multiple evenly distributed grooves 201 that are wider at the bottom and narrower at the top. The grooves 201 are used to accommodate and temporarily fix the impurities. When the armored conveyor belt 2 moves upward, the impurities will fall into the grooves 201, reducing the possibility of them being resuspended due to liquid disturbance.

[0035] Considering that if the armored conveyor belt 2 carries a large amount of impurities, some of the impurities may be squeezed into the gap between the armored conveyor belt 2 and the inner wall of the cleaning machine frame 1 during operation, causing jamming or even hindering the normal rotation of the armored conveyor belt 2, the device is designed as follows.

[0036] refer to Figure 4 The storage box 21 is fixedly connected to the left and right side walls with support columns 22. The cleaning machine frame 1 is provided with irregular guide grooves 26 on the left and right side walls. The support columns 22 are slidably embedded in the corresponding guide grooves 26 to guide the storage box 21 to slide out laterally at a high position. The top outer side of the guide groove 26 is provided with a connecting plate 34 to limit the travel of the storage box 21 to slide out laterally.

[0037] refer to Figure 5 The connecting frame 29 has two symmetrically distributed fixed seats 3 fixed to its side wall. Each fixed seat 3 is hinged with a lever 31. A limiting plate 33 is slidably connected between the two fixed seats 3. The bottom of the limiting plate 33 is attached to the top left area of ​​the armored conveyor belt 2. The function of the limiting plate 33 is to constrain impurities on the side of the armored conveyor belt 2 away from the inner wall of the cleaning machine frame 1 during the conveying process, so as to prevent them from entering the side gap and causing jamming.

[0038] Two symmetrically arranged T-shaped frames 32 are fixedly connected to the top of the limiting plate 33. Each T-shaped frame 32 has a horizontal groove 322. The free end of the lever 31 is embedded and slidably connected in the corresponding horizontal groove 322. The inner cavity side wall of the cleaning machine frame 1 is fixedly connected with a squeezing column corresponding to the lever 31. Initially, the squeezing column is located directly above the corresponding lever 31.

[0039] Because the cleaning machine frame 1 adopts a semi-enclosed structure, when the lifting frame 13 drives the entire moving impurity collection structure to move upward, the side wall of the cleaning machine frame 1 is freed from the enclosure constraint of the armored conveyor belt 2. At this time, the lever 31 moves upward with the whole and contacts the corresponding squeezing column above. It rotates under the squeezing action. The rotation of the lever 31 drives the T-shaped frame 32 and the limiting plate 33 fixed to it to move upward synchronously through the transverse groove 322, thereby releasing the lateral obstruction of the limiting plate 33 on the impurities on the armored conveyor belt 2. As the storage box 21 moves upward, the support column 22, guided by the guide groove 26, drives the storage box 21 to slide out laterally at a high position to receive the impurities on the side of the armored conveyor belt 2 close to the cleaning machine frame 1. Subsequently, the impurities fall into the storage box 21 below under the action of the conveyor belt movement.

[0040] To further prevent impurities from remaining in trench 201, refer to Figure 5 The storage box 21 is provided with a plurality of cleaning blocks 4 on its top. The cleaning blocks 4 are embedded and slide in the grooves 201 on the armored conveyor belt 2. When the armored conveyor belt 2 continues to run through the area of ​​the storage box 21, the cleaning blocks 4 are inserted into the grooves 201 to scrape off the residual impurities inside, so that the grooves 201 are clean and unobstructed, and to avoid the accumulation of impurities affecting the subsequent conveying efficiency and the stability of equipment operation.

[0041] In summary, by using the groove 201 to accommodate impurities and reduce the possibility of re-suspension due to liquid disturbance, by using the limiting plate 33 to laterally block impurities on the armored conveyor belt 2 to prevent impurities from getting stuck in the gaps, by using the squeezing column and lever 31 to squeeze the limiting plate 33 upward to remove the restriction, and by using the cleaning block 4 and the groove 201 to prevent impurities from remaining, the system achieves efficient collection, safe transportation and unloading of impurities, effectively solving the problems of slow impurity settling, easy jamming and difficult cleaning in traditional ultrasonic cleaning machines.

[0042] refer to Figure 6 A synchronous shaft 42 is connected to the connecting frame 29. The synchronous shaft 42 and the rotating shaft 23 are connected by a synchronous belt 41. An eccentric wheel 44 is keyed to one end of the synchronous shaft 42. A striking plate 45 located on the back of the armored conveyor belt 2 is slidably connected to the connecting frame 29. A transmission frame 43 is fixed to the striking plate 45. A slot is opened on the transmission frame 43. The slot of the transmission frame 43 and the working end of the eccentric wheel 44 are embedded and slidably connected.

[0043] During the upward movement of the armored conveyor belt 2, the rotating shaft 23 drives the synchronous belt 41, which in turn drives the synchronous shaft 42 to rotate synchronously, thereby causing the eccentric wheel 44 to rotate. The eccentric motion of the eccentric wheel 44 is converted into the reciprocating linear motion of the transmission frame 43 through its sliding cooperation with the groove of the transmission frame 43. This causes the striking plate 45 to periodically strike the back of the armored conveyor belt 2. This striking action can effectively shake off impurities that are attached to or stuck in the groove 201, further preventing impurity residue.

[0044] The placement structure includes a support frame 141 hinged to the placement frame 14. The top of the support frame 141 is provided with multiple placement units for accommodating optical lenses. A fixing block 27 is fixedly connected to one side of the support frame 141. A vertically arranged limiting groove 28 is opened at the corresponding position on the inner cavity side wall of the cleaning machine frame 1. The limiting groove 28 is located above the placement frame 14, and the fixing block 27 is embedded and slidably fitted in the limiting groove 28.

[0045] In the initial state, the fixing block 27 is supported at the bottom of the limiting groove 28, which raises one end of the receiving frame 141 that is fixed thereto, and the whole is tilted. This tilting design is intended to keep the optical lens being carried in a non-horizontal state during the ultrasonic cleaning process, which is conducive to the smoother removal of attached impurities under the combined action of cavitation effect and gravity, thereby improving cleaning efficiency.

[0046] When the lifting frame 13 moves the entire mass collection structure upward, the fixing block 27 disengages from the support surface at the bottom of the limiting groove 28. Under the action of gravity, the receiving frame 141 rotates downward and finally fits smoothly against the top surface of the placement frame 14, so that the optical lens changes from an inclined state to a horizontal state, which facilitates subsequent smooth lifting and removal operations.

[0047] All components of this device that come into contact with the cleaning fluid are treated with anti-corrosion measures to resist the chemical corrosion of the cleaning fluid; the motor 11 used for driving is equipped with a sealed protective shell to ensure that the electrical components operate safely and reliably in a humid environment.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
