Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, and in particular to a dust removal device for the surface of optical lenses. Background Technology

[0002] Optical lenses are transparent materials made of optical materials such as glass or resin. After being polished, they are used in various devices or apparatuses to achieve the purpose of protection or to improve optical performance.

[0003] Chinese utility model patent CN220361635U discloses a surface dust removal device for optical lenses, comprising: a dust removal device base, a sliding circular groove formed in the upper part of the dust removal device base, main support columns provided on the upper surface of the dust removal device base, the main support columns being fixed to the upper surface of the dust removal device base by welding, a locking connector provided above the main support columns, the locking connector being fixed to the upper part of the main support columns by welding, a fixing groove formed in the interior of the locking connector, a sliding hole formed in the center of the interior of the locking connector, a locking rotating shaft provided inside the locking connector, the locking rotating shaft passing through the fixing groove inside the locking connector, and the locking rotating shaft being fixed inside the locking connector by rotational connection. When using the above-mentioned dust removal equipment, the optical lens to be dusted is placed on the lens placement base. The active locking block drives the driven locking block to lock the optical lens. After the external blowing device is turned on, the air will enter the air box through the air inlet and blow out evenly from the air outlet. At this time, the sliding support block can be used for multi-angle dust removal, thereby achieving the effect of dust removal on the optical lens.

[0004] When using the dust removal equipment disclosed in the aforementioned utility model patent, the optical lens is placed above the lens placement base. Therefore, the air blown out by the external blowing device can only contact the upper surface of the optical lens. If the other side of the optical lens needs to be dusted, the optical lens needs to be manually flipped over and re-clamped, which is cumbersome and affects the dust removal efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an optical lens surface dust removal device, which solves the problem that manual flipping of optical lenses during the dust removal process is cumbersome and affects dust removal efficiency.

[0006] According to an embodiment of this utility model, an optical lens surface dust removal device includes a frame, on which a placement tray is provided and a plurality of positioning grooves are spaced apart along the circumference of the placement tray. Each positioning groove has a through hole penetrating the placement tray. The frame also includes two liftable movable frames and a drive assembly respectively connected to the two movable frames. The two movable frames are located on the upper and lower sides of the placement tray, and the drive assembly drives the two movable frames to simultaneously move closer to or away from the placement tray. Each movable frame has a plurality of rotating rods spaced apart along the circumference of the placement tray. The number of rotating rods is the same as the number of positioning grooves and is aligned with the through holes. One end of each rotating rod near the placement tray has a wiping plate, and the other end away from the placement tray has a first eccentric shaft. The wiping plate has a dust removal cloth on its side near the placement tray. The movable frame also includes a first drive motor, and the output end of the first drive motor has a second eccentric shaft. A drive disk is rotatably connected to the second eccentric shaft, and the drive disk has a plurality of first mounting holes corresponding to and cooperating with the first eccentric shaft.

[0007] Furthermore, the frame is provided with a vertical guide rod, and the movable frame is provided with a guide hole that cooperates with the guide rod.

[0008] Furthermore, the drive assembly includes a second drive motor and a drive rod disposed at the output end of the second drive motor. The drive rod is vertically disposed on the frame and rotatably connected to the frame, and the drive rod is provided with two threaded portions with opposite directions of rotation at intervals. The movable frame is provided with threaded holes that mate with the threaded portions.

[0009] Furthermore, the movable frame is provided with a plurality of second mounting holes spaced apart along the circumference of the placement tray. The number of the second mounting holes is the same as the number of the through holes and they are aligned one by one. The rotating rods are rotatably disposed in the second mounting holes.

[0010] Furthermore, the movable frame is also provided with a third mounting hole that cooperates with the second eccentric shaft, and the third mounting hole is coaxially arranged with the placement plate.

[0011] Furthermore, the placement tray is provided with an annular groove and a plurality of air guide grooves respectively communicating with the annular groove, and the end of the air guide groove away from the annular groove is respectively connected to the positioning groove or the through hole.

[0012] Furthermore, the placement tray is also provided with a connector, which communicates with the annular groove.

[0013] Furthermore, the dust removal cloth is cross-shaped and is bonded to the wiping plate.

[0014] Compared with existing technologies, this utility model has the following advantages: By employing positioning slots on the placement tray to accommodate optical lenses to be cleaned, after the optical lenses are placed into their respective positioning slots, the drive assembly is activated to move two movable frames closer to the placement tray. This causes the wiping plate on the movable frame above the placement tray to extend into the positioning slot until the dust removal cloth contacts the upper surface of the optical lens, while the wiping plate on the movable frame below the placement tray passes through the through hole to contact the lower surface of the optical lens. Then, the first drive motors on the two movable frames are activated to drive the second eccentric shaft to rotate. The drive wheel is activated, and through the cooperation of the first eccentric shaft and the drive wheel, all rotating shafts rotate synchronously. This allows the dust removal cloth to wipe both the top and bottom surfaces of the optical lens simultaneously, eliminating the need to flip the optical lens. After dust removal, the first drive motor is turned off, and the drive assembly moves the two movable seats away from the placement tray, allowing the optical lens to be removed from the placement tray. This solves the technical problem of the cumbersome manual flipping of the optical lens during dust removal, which affects the dust removal efficiency. It achieves the technical effect of simultaneously removing dust from both the top and bottom surfaces of the optical lens, simplifying the operation steps, and improving the dust removal efficiency.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes an optical lens surface dust removal device for wiping the surface of an optical lens to remove dust adhering to the surface of the optical lens.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The optical lens surface dust removal device includes a frame 1, on which a placement tray 2 is provided, and multiple positioning slots 21 are spaced apart along the circumference of the placement tray 2. The positioning slots 21 are used to place the optical lens to be dusted, and each positioning slot 21 has a through hole 22 penetrating the placement tray 2. The frame 1 also has two liftable movable frames 3 and a drive assembly 4 that is pulsatingly connected to the two movable frames 3. The two movable frames 3 are located on the upper and lower sides of the placement tray 2, and the drive assembly 4 drives the two movable frames 3 to move closer to or away from the placement tray 2. Multiple rotating rods 5 are spaced apart along the circumference of the placement tray 2 on the movable frames 3. The number of rotating rods 5 is the same as the number of positioning slots 21 and is aligned with the through holes 22. The end of each rotating rod 5 near the placement tray 2 is provided with a wiping plate 51, and the end away from the placement tray 2 is provided with a first eccentric shaft 52. The side of the wiping plate 51 near the placement tray 2 is provided with a dust removal cloth 53. The drive assembly 4 drives the two movable frames 3 to move closer to or away from the placement tray 2. When the movable frame 3 approaches the placement tray 2, the wiping plate 51 located above the placement tray 2 extends into the positioning groove 21, causing the dust removal cloth 53 to contact the upper surface of the optical lens. Simultaneously, the wiping plate 51 located below the placement tray 2 passes through the through hole 22, causing the dust removal cloth 53 to contact the lower surface of the optical lens. The movable frame 3 is also equipped with a first drive motor 31, and the output end of the first drive motor 31 is equipped with a second eccentric shaft 32. A drive disk 33 is rotatably connected to the second eccentric shaft 32. The drive disk 33 is equipped with a plurality of first mounting holes that correspond one-to-one with the first eccentric shaft 52. When the first drive motor 31 drives the second eccentric shaft 32 to rotate, it drives the drive disk 33 to move. Through the cooperation between the drive disk 33 and the first eccentric shaft 52, the power output by the first drive motor 31 is transmitted to each of the rotating rods 5, causing each of the rotating rods 5 to rotate synchronously. When the rotating rods 5 rotate, the dust removal cloth 53 wipes the surface of the optical lens to remove the dust adhering to the surface of the optical lens.

[0023] Specifically, the operation steps for removing dust from the surface of an optical lens using the optical lens surface dust removal device provided in this embodiment are as follows: Place the optical lenses to be dusted into the respective positioning slots 21. After the optical lenses are placed, activate the drive assembly 4 to drive the two movable frames 3 closer to the placement tray 2. This causes the wiping plate 51 on the movable frame 3 above the placement tray 2 to extend into the positioning slots 21 until the dust removal cloth 53 contacts the upper surface of the optical lens. Simultaneously, the wiping plate 51 on the movable frame 3 below the placement tray 2 passes through the through hole 22, causing the dust removal cloth 53 to contact the lower surface of the optical lens. The first drive motors 31 on the two movable frames 3 are turned on to drive the second eccentric shafts 32 to rotate. When the second eccentric shafts 32 rotate, they drive the drive wheels to move, and through the cooperation of the first eccentric shafts 52 and the drive wheels, they drive each rotating shaft to rotate synchronously. When the rotating shafts rotate, the dust removal cloths 53 wipe the surface of the optical lens, and the dust removal cloths 53 located on both sides of the optical lens wipe both the upper and lower surfaces of the optical lens at the same time. After the dust removal is completed, the first drive motors 31 are turned off, and the drive assembly 4 drives the two movable seats away from the placement tray 2, so that the optical lens can be removed from the placement tray 2. The optical lens surface dust removal device provided in this embodiment can remove dust from both the upper and lower surfaces of the optical lens at the same time, without the need to flip and clamp the optical lens, simplifying the steps of the optical lens dust removal operation and improving the dust removal efficiency.

[0024] like Figure 1 and Figure 2 As shown, the frame 1 is provided with a vertical guide rod 11, and the movable frame 3 is provided with a guide hole 34 that mates with the guide rod 11. The movable frame 3 is installed on the frame 1 through the engagement of the guide hole 34 and the guide rod 11, allowing the movable frame 3 to move axially along the guide rod 11 on the frame 1. This ensures a secure fit between the movable frame 3 and the frame 1 while preventing the movable frame 3 from deviating from the preset direction during movement, thereby improving the structural stability of the optical lens surface dust removal device.

[0025] like Figure 3As shown, the drive assembly 4 includes a second drive motor 41 and a drive rod 42 disposed at the output end of the second drive motor 41. The drive rod 42 is vertically disposed on the frame 1 and rotatably connected to the frame 1. The drive rod 42 has two threaded portions 43 with opposite directions of rotation spaced apart. The movable frame 3 is provided with threaded holes 35 that mate with the threaded portions 43. When the drive rod 42 rotates under the drive of the second drive motor 41, the engagement of the threaded portions 43 with the threaded holes 35 drives the movable frame 3 to move axially along the drive rod 42, thereby driving the movable frame 3 to rise and fall vertically. The opposite directions of rotation of the two threaded portions 43 cause the two movable frames 3 to move in opposite directions under the drive of the drive rod 42, allowing the two movable frames 3 to simultaneously move closer to or further away from the placement tray 2, facilitating the adjustment of the position of the movable frame 3.

[0026] Please refer to Figure 2 The movable frame 3 has multiple second mounting holes spaced circumferentially along the placement tray 2. The number of second mounting holes is the same as the number of through holes 22, and they are aligned one by one. The rotating rods 5 are rotatably disposed in the second mounting holes. The second mounting holes on the placement tray 2 are used to mount the rotating rods 5 onto the movable frame 3, and the second mounting holes are aligned one by one with the through holes 22, so that the rotating rods 5 remain aligned with the through holes. This ensures that when the movable frame 3 moves toward the placement tray 2, the wiping plate 51 can smoothly enter the positioning groove 21 or pass through the through hole 22.

[0027] In detail, the movable frame 3 is also provided with a third mounting hole that mates with the second eccentric shaft 32. The third mounting hole is coaxially arranged with the placement disk 2. The second eccentric shaft 32 is mounted to the movable frame 3 through the mating with the third mounting hole, which helps to improve the stability of the mating between the second eccentric shaft 32 and the movable frame 3, and prevents the drive disk 33 from moving unexpectedly when driven by the second eccentric shaft 32.

[0028] Please combine Figure 3 and Figure 4The placement tray 2 is provided with an annular groove 23 and a plurality of air guide grooves 24 respectively communicating with the annular groove 23. The end of the air guide groove 24 away from the annular groove 23 is respectively connected to the positioning groove 21 or the through hole 22. The annular groove 23 provided on the placement tray 2 is used to communicate with an external vacuum generator, and the air guide grooves 24 provided on the placement tray 2 connect the annular groove 23 with the positioning groove 21 or the through hole 22. When the external vacuum generator is turned on, the dust in the positioning groove 21 and the through hole 22 can be sucked in along the air guide grooves 24 and the annular groove 23, avoiding the dust wiped off the optical lens by the dust removal cloth 53 from remaining in the positioning groove 21 or the through hole 22, and facilitating the centralized treatment of the wiped-off dust.

[0029] In this embodiment, the placement tray 2 is further provided with a connector 25, which communicates with the annular groove 23. The connector 25 is used to connect to an external vacuum generator, facilitating the connection between the annular groove 23 and the external vacuum generator.

[0030] like Figure 1 As shown, the dust removal cloth 53 is cross-shaped and is bonded to the wiping plate 51. The cross-shaped design of the dust removal cloth 53 allows dust wiped off the optical lens to accumulate at its edges, enabling the dust to be quickly sucked away by an external vacuum generator or to adhere to the cloth and detach from the lens. The cloth 53 is bonded to the wiping plate 51, allowing for easy replacement by tearing it off. This prevents dust adhering to the cloth from affecting the dust removal effect of the bond between the cloth 53 and the wiping plate 51.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
