Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more specifically to an optical lens packaging material cleaning device. Background Technology

[0002] As a core component of precision optical devices, the surface quality of optical lenses directly affects imaging accuracy and optical performance. However, during the production process, secondary damage to the lens surface caused by residues from packaging materials (mainly blister packaging materials such as PVC and PET) has become a pain point in the industry.

[0003] Specifically, this manifests in the following ways: ① Surface residues due to material properties: During thermoforming and cutting, vacuum forming materials easily produce powdery residues. After transportation and vibration, these particles, with a Mohs hardness of 4-6H, can scratch the lens surface, forming invisible scratches 0.2-5μm deep. This is especially true for lenses made of high-refractive-index resin materials (such as polycarbonate), where the surface Mohs hardness is only 2-3H, making them more susceptible to mechanical damage from residues. ② Limitations of traditional cleaning methods: Current manual cleaning methods combine ethanol wiping with ultrasonic pre-cleaning, which have the following drawbacks: uneven pressure during manual operation leads to localized stress concentration, accelerating the propagation of subsurface cracks; cotton fiber residue triggers capillary adsorption, exacerbating the retention of contaminants in microstructure areas; ultrasonic waves exhibit standing wave phenomena, creating cleaning blind spots on complex curved surfaces (such as aspherical and free-form surfaces); and the residue removal rate is less than 70%. Experiments show that these residues undergo phase transformation expansion when temperature and humidity change, leading to stress-induced peeling of the coating layer.

[0004] Meanwhile, manual cleaning also has the problem that the cleaning solution cannot be reused, which wastes the cleaning solution and increases cleaning costs.

[0005] Therefore, developing an optical lens packaging material cleaning equipment that enables low-cost and more thorough cleaning of optical lens packaging materials is a means to improve the yield of optical lens products. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an optical lens packaging material cleaning device, which achieves the objective of solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the embodiments of the present invention specifically adopt the following technical solutions:

[0008] An optical lens packaging material cleaning device includes a vertical cleaning machine. The vertical cleaning machine has a housing with a control panel, an outer cylinder connected inside the housing, an inner cylinder nested inside the outer cylinder, a pulsator inside the inner cylinder, a drive shaft for driving the pulsator to rotate, a lint collector on the side wall of the inner cylinder, and a liftable support basket inside the inner cylinder. Multiple cleaning baskets are arranged in an array inside the support basket, and the cleaning baskets are filled with materials to be cleaned at intervals.

[0009] The inner cylinder contains cleaning fluid. The carrier basket carries the cleaning basket downward until the material to be cleaned is immersed in the cleaning fluid and cleaned by the rotating impeller. Alternatively, the carrier basket carries the cleaning basket upward to remove it from the cleaning fluid, and then rotates to spin-dry it.

[0010] This invention utilizes a liftable carrier basket to move the cleaning basket up and down to select for cleaning or spin-drying. During the cleaning process, particulate impurities are removed. The cleaning solution can be reused multiple times, resulting in lower costs. Furthermore, the use of a vertical impeller cleaning machine allows the forward and reverse impeller to drive the water flow and form a vortex, achieving multi-angle cleaning without dead angles, resulting in a more thorough cleaning.

[0011] Furthermore, the carrying basket is a trough-shaped body with an open top and a hollow bottom. The carrying basket is raised and lowered by a lifting mechanism, and the carrying basket is rotatably connected to the lifting mechanism.

[0012] The rotatable connection between the carrying basket and the lifting mechanism allows the carrying basket to slowly rotate when subjected to the impact of the vortex of the cleaning liquid flow, thereby enabling the cleaning liquid to rinse the material being cleaned in multiple directions and avoid cleaning dead corners.

[0013] Furthermore, the cleaning basket is a fan-shaped columnar frame made of metal mesh. Multiple cleaning baskets are arranged in a ring inside the carrying basket. The cleaning baskets are connected to the carrying basket by buckles. The cleaning basket is provided with a loading space with an opening facing the inner cylinder. The opening of the loading space is closed by the inner side wall of the carrying basket. Except for the opening, the side walls of the loading space have hollow holes formed by metal wires.

[0014] The loading space is used to load the materials to be cleaned. Since the opening of the loading space is closed by the carrying basket, the materials to be cleaned only need to be placed into the loading space without additional fixing, which simplifies the operation process and saves more time.

[0015] Furthermore, the plane containing the loading space is radially aligned with the cleaning basket and forms an angle with the vertical plane, which facilitates the cleaning fluid in driving the carrying basket to rotate.

[0016] Furthermore, a braking device is provided inside the inner cylinder. The braking device contacts the carrying basket after the carrying basket rises, so that the carrying basket and the inner cylinder are relatively fixed.

[0017] The braking device engages or squeezes the carrier basket to fix it relative to the inner cylinder. At this time, when the inner cylinder rotates, the carrier basket can carry the cleaning basket to rotate, generating a rapid centrifugal force to throw off the cleaning liquid. At the same time, the carrier basket is separated from the cleaning liquid, so there is no need to drain it. Dehydration can be achieved simply by using the clutch mechanism of the cleaning machine to make the inner cylinder and impeller rotate together. The cleaning liquid at the bottom can still be used for the next cleaning.

[0018] Furthermore, the impeller includes an upper impeller and a lower impeller. The upper impeller is an annular body with multiple upward-protruding water guide covers arranged in an array along the circumference of the upper impeller. Water passage holes are provided on the upper impeller outside the water guide covers. The inner ring of the upper impeller is rotatably connected to the lower end of the support basket and rises and falls with the support basket. The lower impeller includes a connecting plate and water guide plates. Water guide plates are arrayed on the connecting plate. The lower impeller is fixedly connected to the drive shaft. The upper impeller is connected to the drive shaft after the support basket descends and rotates with the drive shaft.

[0019] This technical solution solves the problem that the water guide shroud on the impeller generates an outward rotational force during dehydration. Because the upper impeller detaches from the cleaning fluid after rising with the support basket, its rotation does not affect the cleaning fluid, and the lower impeller has a smaller impact on the cleaning fluid.

[0020] Furthermore, it also includes a downpipe, which is connected to the support basket via a connecting rod. The support basket is rotatably connected to the lifting mechanism via a first rotating frame inside the downpipe. A connecting pipe is provided at the center of the upper impeller. The connecting pipe is connected to the upper impeller via a rib plate. The upper end of the connecting pipe protrudes from the upper impeller and is rotatably connected to the downpipe via a second rotating frame.

[0021] The downpipe is mainly used to collect impurities that easily float on the surface of the cleaning liquid and transport them to the area below the upper impeller. Suspended or settled impurities enter the area below the upper impeller through the water holes and are driven by the water guide plate of the lower impeller into the lint collector for filtration.

[0022] Furthermore, the drive shaft passes through the outer cylinder and the inner cylinder from bottom to top. The lower end of the drive shaft is connected to the housing via a bearing. The drive shaft is connected to mechanical seals corresponding to the outer cylinder and the inner cylinder, and is also equipped with a clutch. When the clutch is working, the inner cylinder rotates synchronously with the impeller. The drive shaft is provided with a connecting section for connecting the lower impeller and a threaded section for connecting a nut to restrict the movement of the lower impeller. Above the connecting section is a connector for connecting the upper impeller. The connector is an elliptical cylinder. The connecting tube on the upper impeller has a hole adapted to the connector.

[0023] Furthermore, the holes in the connecting tube include a gradient hole at the bottom and a first elliptical hole and a second elliptical hole at the top. The major axes of the first elliptical hole and the second elliptical hole are perpendicular to each other. The lower end of the gradient hole is circular, and the upper end gradually changes to be consistent with the first elliptical hole and the second elliptical hole; this facilitates connection and reduces the occurrence of jamming.

[0024] Furthermore, it also includes a drying mechanism, which comprises a hot air section, an air duct, and an air outlet connected in sequence, with the air outlet facing vertically toward the upper end of the washing basket.

[0025] The beneficial effects of the embodiments of the present invention are as follows:

[0026] 1. This invention utilizes a liftable carrier basket to move the cleaning basket up and down to select for cleaning or spin-drying. During the cleaning process, particulate impurities are removed. The cleaning solution can be reused multiple times, resulting in lower costs. Furthermore, the use of a vertical impeller cleaning machine allows the forward and reverse impeller to drive the water flow and form a vortex, achieving multi-angle cleaning without dead angles, resulting in a more thorough cleaning.

[0027] 2. The arrangement of the support basket and the cleaning basket in this invention allows the support basket to be cleaned when it descends. During the cleaning process, the support basket rotates, reducing the problem of cleaning dead angles. When the support basket rises, it rotates simultaneously with the inner cylinder, which facilitates spin drying.

[0028] 3. The impeller of the present invention has a split structure, which prevents the cleaning liquid from extending too much upward due to centrifugal force during the spin-drying process. This reduces the height of the cleaning machine, increases the height of the cleaning basket, and allows for the cleaning of a larger amount of material at one time.

[0029] 4. The connector of the drive shaft and the connecting pipe of the upper impeller of the present invention are specially designed to reduce the problem of connection jamming between the upper impeller and the drive shaft during the rising and falling process. Attached Figure Description

[0039] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0040] See Figure 1 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention discloses an optical lens packaging material cleaning device, including a vertical cleaning machine, which is similar to a household washing machine but larger in size. The vertical cleaning machine has a housing 2 with a control panel 1. An outer drum 4 is connected to the housing 2 via a suspension assembly 3. An inner drum 5 is nested inside the outer drum 4. The inner drum 5 has drainage holes on its side wall and a pulsator at the bottom of the inner drum 5. The pulsator is driven by a drive shaft 6 that passes through the inner drum 5 and the outer drum 4. A driven wheel 7 located below the outer drum 4 is connected to the lower part of the drive shaft 6. A drive motor is provided between the outer drum 4 and the housing 2. A drive wheel is provided on the output shaft of the drive motor. The drive wheel and the driven wheel 7 are connected by a belt 8. The drive shaft 6 is also provided with a mechanical seal 9 corresponding to the outer drum 4 and the inner drum 5. A clutch 10 is also provided on the drive shaft 6 between the outer drum 4 and the inner drum 5. When the clutch 10 is not working, the drive shaft 6 only drives the pulsator to rotate reciprocally. When the clutch 10 is working, the drive shaft 6 drives the inner drum 5 to rotate together with the pulsator.

[0041] The bottom of the inner cylinder 5 is also provided with a water guiding channel 11 located outside the impeller. The water guiding channel 11 is connected to the wire debris collector 12 on the side wall of the inner cylinder 5. When the impeller rotates, the cleaning liquid (water) in the inner cylinder 5 is guided into the water guiding channel 11 and transported to the wire debris collector 12 for filtration. Small particulate impurities in the water are intercepted by the filter screen of the wire debris collector 12, and the filtered water is returned to the inner cylinder 5 for continued use.

[0042] The upper end of the housing 2 is provided with an openable cover plate 13 and a lifting mechanism 14. The lifting mechanism 14 is a telescopic cylinder, a telescopic motor, or other telescopic mechanism. The inner cylinder 5 is provided with a carrying basket 15. The carrying basket 15 is a trough-shaped body with an open top and a hollow bottom. The carrying basket 15 is raised and lowered by the lifting mechanism 14. The carrying basket 15 is rotatably connected to the lifting mechanism 14. When the carrying basket 15 is subjected to the impact of the vortex of the cleaning fluid, it can slowly rotate, so that the cleaning fluid can rinse the material being cleaned in multiple directions and avoid cleaning dead corners. Multiple [items] are arranged in an array inside the carrying basket 15. The cleaning basket 16 is a fan-shaped columnar frame made of metal mesh. Multiple cleaning baskets 16 are arranged in a ring inside the carrying basket 15. The cleaning baskets 16 are connected to the carrying basket 15 by buckles. The cleaning basket 16 is provided with a loading space 17 with the opening facing the inner cylinder. The opening of the loading space 17 is closed by the inner side wall of the carrying basket 15. Therefore, the material to be cleaned only needs to be placed into the loading space 17 without additional fixing, which simplifies the operation process and saves more time. Except for the opening, the other side walls of the loading space 17 have hollow holes formed by metal wire connection.

[0043] The loading space 17 of the cleaning basket 16 contains optical lens packaging material (blister material), i.e., the material to be cleaned.

[0044] A liquid level sensor 18 is installed on the inner wall of the outer cylinder 4. The liquid level sensor 18 is higher than the lint collector 12. The inner cylinder 5 is filled with cleaning fluid. The liquid level of the cleaning fluid is flush with the liquid level sensor 18. During cleaning, the support basket 15 carries the cleaning basket 16 downward until the material to be cleaned is immersed in the cleaning fluid and is cleaned by the rotation of the impeller. After cleaning, the support basket 15 carries the cleaning basket 16 upward to remove it from the cleaning fluid. The support basket 15 carries the cleaning basket 16 and rotates to spin dry. The rotation power can be selected as motor drive or other power drive mechanism. It can directly drive the support basket 15 or be driven by other transmission components.

[0045] The lifting basket 15 carries the cleaning basket 16 up and down to select for cleaning or spin drying. The removal of particulate impurities is completed during the cleaning process. The cleaning solution can be used for cleaning multiple times, which is low-cost. The vertical impeller cleaning machine uses a forward and reverse impeller to drive the water flow to form a vortex, achieving multi-angle cleaning without dead angles, and cleaning more thoroughly.

[0046] In some embodiments of the present invention, the plane of the loading space 17 is radially along the cleaning basket 16 and forms an angle with the vertical plane. In this way, the material to be cleaned can be driven by the water flow under the impact of the water flow, thereby causing the carrying basket 15 to rotate. After the carrying basket 15 rotates, the cleaning dead angle of the water flow on the material to be cleaned can be reduced or even eliminated.

[0047] In some embodiments of the present invention, a braking device 19 is provided inside the inner cylinder 5. The braking device 19 contacts the carrying basket 15 after the carrying basket 15 rises, thus fixing the carrying basket 15 relative to the inner cylinder 5. The braking device 19 engages or presses against the carrying basket 15, for example... Figure 2 In the middle, the outer diameter of the upper end of the outer wall of the carrying basket 15 is small and the outer diameter of the lower end is large. The braking device 19 is ring-shaped. When the carrying basket 15 rises, the braking device 19 and the carrying basket 15 are pressed into contact. Or in some other embodiments, the braking device 19 and the carrying basket 15 are pressed into contact. At this time, when the inner cylinder 5 rotates, the carrying basket 15 can carry the cleaning basket 16 to rotate, generating a rapidly rotating centrifugal force to shake off the cleaning liquid. Because the carrying basket 15 is separated from the cleaning liquid during the spin-drying process, there is no need to drain the water. The inner cylinder 5 and the impeller can be rotated together by the clutch of the washing machine to achieve dehydration. The cleaning liquid below can still be used for the next cleaning.

[0048] The above structure is already capable of cleaning optical lens packaging materials. However, because the impeller rotation during spin drying also drives the water to all sides, causing the water to rise along the inner wall of the inner cylinder 5, the height of the shell 2 and the inner cylinder 5 needs to be made relatively high, or the height of the carrying basket 15 needs to be reduced to avoid water contacting the material being cleaned during spin drying. However, there is another embodiment of the present invention that can solve this problem.

[0049] like Figure 6 , Figure 7 and Figure 8As shown, in another embodiment of the present invention, the impeller includes an upper impeller 20 and a lower impeller 21. The upper impeller 20 is an annular body, a planar circular ring, and can also be configured with a smooth filtering slope. The upper impeller has multiple upward-protruding water guide covers 22, which are arranged in a circular array along the circumference of the upper impeller 20. The upper end of the water guide covers 22 is higher than the water guiding channel 11 when the upper impeller 20 and the lower impeller 21 are connected. The water guide covers 22 are used to push the water flow in the inner water cylinder 5 to form a vortex when the upper impeller 20 rotates. The upper impeller 20, excluding the water guide covers 22, is provided with water passage holes 23. The inner ring is rotatably connected to the lower end of the support basket 15 and rises and falls with the support basket 15; the lower impeller 21 includes a connecting plate 25 and a water guide plate 24. The connecting plate 25 is a flat circular plate with a connecting boss 26 at its center. The connecting boss 26 has a connecting hole 27 at its center for connecting the drive shaft 6. The water guide plate 24 is arranged on the connecting plate 25. The upper end of the water guide plate 24 is not higher than the upper end of the connecting boss 26 to avoid interference with the upper impeller 20. The lower impeller 21 is fixed to the drive shaft 6 by a nut. The upper impeller 20 is connected to the drive shaft 6 after the support basket 15 descends and rotates with the drive shaft 6.

[0050] In this way, during washing, the upper impeller 20 and the lower impeller 21 combine to form the existing impeller structure, which is used to drive the water flow and form a washing vortex. During spin drying, the upper impeller 20 and the lower impeller 21 separate and no longer drive the water to rotate. Only the lower impeller 21 rotates with the inner cylinder 5. The viscosity of the water is very small and not enough to make the water flow generate a large centrifugal force. Therefore, the height of the inner cylinder 5 can be reduced, and the height of the carrying basket 15 and the washing basket 16 can be increased to load more materials to be washed.

[0051] Because optical lens packaging materials are thermoforming materials, the density of each type of packaging material varies, ranging from 0.74 to 1.12 g / cm³. 3 The unequal distribution of impurities results in some particles remaining suspended in the water, some sinking to the bottom, and some floating on the surface. Particles suspended in the water and those sinking to the bottom can enter the lower impeller 21 through the water passage 23 during washing and be guided into the water guide channel 11 for filtration. However, impurities floating on the surface have difficulty breaking through the vortex to enter the lower impeller 21. Therefore, as... Figure 2As shown, in some embodiments of the present invention, a drain pipe 28 is also included. The drain pipe 28 is connected to the support basket 15 via a fixed rod. The support basket 15 is rotatably connected to the lifting mechanism 14 via a first rotating frame 29 inside the drain pipe 28, thus forming a rotatable connection between the support basket 15 and the lifting mechanism 14. A connecting pipe 30 is provided at the center of the upper impeller 20. The connecting pipe 30 is connected to the upper impeller 20 via a rib plate 31. The upper end of the connecting pipe 30 protrudes from the upper impeller 20 and is rotatably connected to the drain pipe 28 via a second rotating frame 32, thus forming a rotatable connection between the inner ring of the upper impeller 20 and the lower end of the support basket 15. The drain pipe 28 and the upper impeller 20 are vertically opposite each other. When the support basket 15 falls to clean, the upper end of the drain pipe 28 is located at the bottom of the vortex, allowing water on the surface of the vortex to flow into the drain pipe 28, and then into the lower impeller 21 via the upper impeller 20, thereby achieving the filtration of particulate impurities on the water surface to ensure the cleanliness of the cleaning solution.

[0052] Both the first rotating frame 29 and the second rotating frame 32 include a sleeve and a connecting plate. Multiple connecting plates are connected in a circumferential array around the sleeve. The sleeve contains a bearing for connecting to the connecting pipe or the lifting mechanism. The outer ends of the connecting plates are connected to a drain pipe.

[0053] The downpipe 28 is mainly used to collect impurities that are easy to float on the surface of the cleaning liquid and transport them to the area below the upper impeller 20. The suspended or settled impurities enter the area below the upper impeller 20 through the water hole 23 and are driven into the lint collector 12 by the water guide plate 24 of the lower impeller 21 for filtration.

[0054] like Figure 5 As shown, the main body of the drive shaft 6 is a cylinder. The drive shaft 6 passes through the outer cylinder 4 and the inner cylinder 5 from bottom to top. Its lower end has a shoulder that is connected to the inner bottom surface of the housing 2 via a bearing. The upper end is provided with a hexagonal prism-shaped connecting section 33 for connecting the lower impeller 21. The upper end of the connecting section 33 is connected with a threaded section 34 for connecting with a nut to press the lower impeller 21 onto the connecting section 33. Above the threaded section 34 is a connector head 35 for connecting the upper impeller 20.

[0055] During the rising and falling of the carrying basket 15, the upper impeller 20 and the connector 35 need to be aligned so that the connector 35 can drive the upper impeller 20 to rotate. If the connector 35 and the hole of the connecting pipe 30 on the upper impeller 20 are not aligned, jamming will occur, which will not only affect work efficiency, but may also damage the equipment.

[0056] Therefore, in some embodiments of the present invention, the connector 35 is an elliptical cylinder, and the connecting tube 30 on the upper impeller 20 is provided with a hole adapted to the connector 35.

[0057] The holes in the connecting pipe 30 include a gradient hole 36 at the bottom and a first elliptical hole 37 and a second elliptical hole 38 at the top. The major axes of the first elliptical hole 37 and the second elliptical hole 38 are perpendicular to each other. The lower end of the gradient hole 36 is circular, and the upper end gradually changes to be consistent with the first elliptical hole 37 and the second elliptical hole 38. This facilitates connection and reduces the occurrence of jamming.

[0058] It also includes a drying mechanism 39, which includes a hot air section, an air duct and an air outlet connected in sequence, with the air outlet facing vertically toward the upper end of the washing basket.

[0059] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
