Description

Technical Field

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

[0002] Optical lenses are lenses manufactured using optical glass. They have different shapes and surface properties and can achieve specific optical functions. Optical lenses require cleaning during the manufacturing process.

[0003] Chinese utility model patent CN210776084U discloses a bulk cleaning and placement rack for optical lenses, comprising four vertical rods, two horizontal rods, two upper longitudinal rods, and one lower longitudinal rod. The two horizontal rods and the lower longitudinal rod are connected to form an I-shaped structure. The four vertical rods are respectively located at both ends of the two horizontal rods. The two upper longitudinal rods are connected between the two vertical rods on the same longitudinal side. Several bottom slots are installed at equal intervals on the lower longitudinal rod, and several side slots corresponding to the bottom slots are installed on the upper longitudinal rods. The rack has multiple slots, allowing for the placement of multiple optical lenses for bulk cleaning.

[0004] The placement rack disclosed in the aforementioned utility model patent only places the optical lens into the slot when in use, without taking any measures to fix the optical lens. When the optical lens is subjected to water flow during the cleaning process, or when the placement rack is shaken to make the water on the surface of the optical lens fall off quickly, the optical lens is prone to move on the placement rack and fall off, causing damage to the optical lens. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bracket for cleaning optical lenses, which solves the problem of optical lenses falling off due to movement on the mounting rack.

[0006] According to an embodiment of this utility model, an optical lens cleaning bracket includes a base, at least one support on the base, and two parallel vertical plates with vertical limiting rods on each vertical plate. The base also has a rotatable rotating rod located between the two vertical plates. Two variable-diameter blocks are symmetrically arranged on the rotating rod, located on opposite sides of the two vertical plates. The distance between the sides of the two variable-diameter blocks closest to the vertical plates varies uniformly along the circumference of the rotating rod. The base also has a movable seat and a drive assembly connected to the movable seat. The movable seat has a rack, and a gear meshing with the rack is fixedly connected to the end of the rotating rod. The drive assembly drives the movable seat to reciprocate along the length of the rack.

[0007] Furthermore, the base is provided with a plurality of supports at intervals, and the plurality of supports are arranged in a matrix on the base.

[0008] Furthermore, the base is provided with a plurality of parallel rotating rods at intervals, and each rotating rod is provided with a plurality of symmetrical variable diameter blocks at intervals, and each set of symmetrical variable diameter blocks corresponds to one of the supports.

[0009] Furthermore, the support also includes a mounting cylinder located between the two vertical plates, the mounting cylinder having a mounting hole that mates with the rotating rod.

[0010] Furthermore, the variable diameter block is provided with a through hole that mates with the rotating rod and a through hole that communicates with the through hole. The rotating rod is provided with a locking hole that aligns with the through hole and a screw that mates with the locking hole is provided in the through hole.

[0011] Furthermore, the base is provided with a dovetail groove, the length direction of which is consistent with the moving direction of the movable seat, and the movable seat is provided with a slider that cooperates with the dovetail groove.

[0012] Furthermore, the driving assembly includes a driving screw rotatably mounted on the base, the length direction of the driving screw being consistent with the moving direction of the movable seat, and the movable seat having a threaded hole that mates with the driving screw.

[0013] Furthermore, a waterproof cover is fixedly connected to the base, and the movable seat, the gear, and part of the drive screw are located within the space enclosed by the waterproof cover and the base.

[0014] Furthermore, a handwheel is fixedly connected to one end of the drive screw, and the end of the drive screw with the handwheel extends out of the space enclosed by the base and the waterproof cover.

[0015] Compared with existing technologies, this utility model has the following advantages: By using a support set on the base for placing the optical lens to be cleaned, the optical lens is positioned between two limiting rods when placed on top of the two vertical plates. The driving component then drives the moving seat to move, and through the cooperation of rack and gear, it drives the rotating rod to rotate. When the rotating rod rotates, it drives the variable diameter blocks located on both sides of the vertical plates to rotate. During the rotation of the variable diameter blocks, the distance between the two variable diameter blocks near the vertical plates gradually decreases until the two variable diameter blocks abut against the two sides of the optical glass. The optical glass is clamped between the two variable diameter blocks, and at the same time, the variable diameter blocks press the optical glass firmly onto the vertical plates, thereby fixing the optical glass and preventing it from falling during the cleaning process. After cleaning, the rotating rod is rotated in the opposite direction to gradually increase the distance between the two variable diameter blocks near the vertical plates until the two variable diameter blocks separate from the optical glass. At this time, the cleaned optical glass can be removed. This solves the technical problem of optical lenses falling due to movement on existing placement racks, and achieves the technical effect of ensuring the stability of the optical lens position during the cleaning process and avoiding the optical lens from falling and breaking. Moreover, it is simple to operate and convenient to use. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 5As shown in the figure, this utility model embodiment proposes a bracket for cleaning optical lenses 6, which is used to place the optical lenses 6 to be cleaned during the processing of optical lenses 6, and to prevent the optical lenses 6 from falling and being damaged when placed in equipment such as ultrasonic cleaners for cleaning.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The optical lens 6 cleaning bracket includes a base 1, on which at least one support 2 is provided. Each support 2 includes two parallel vertical plates 21, each with a vertical limiting rod 22. The vertical plates 21 support the optical lens 6, and the optical lens 6 is positioned between the two limiting rods 22 after being placed on the vertical plates 21. The base 1 also includes a rotatable rotating rod 3, located between the two vertical plates 21. The rotating rod 3 has two symmetrically arranged variable diameter blocks 31, located on opposite sides of the two vertical plates 21. The distance between the sides of the two variable diameter blocks 31 closest to the vertical plates 21 varies uniformly along the circumference of the rotating rod 3. The base 1 also includes a movable moving seat 4 and a driving assembly 5 connected to the moving seat 4. The moving seat 4 has a rack 41, and the end of the rotating rod 3 is fixedly connected to a gear 32 meshing with the rack 41. The driving assembly 5 drives the optical lens 6... The movable seat 4 reciprocates along the length of the rack 41. When the movable seat 4 moves under the drive of the drive assembly 5, the rotating rod 3 is driven to rotate through the cooperation of the rack 41 and the gear 32. When the rotating rod 3 rotates, it drives the variable diameter block 31 to rotate. During the rotation of the variable diameter block 31, the distance between the two variable diameter blocks 31 near the vertical plate 21 gradually decreases or increases with the rotation of the rotating rod 3. When the distance between the two variable diameter blocks 31 near the vertical plate 21 decreases to the point that the two variable diameter blocks 31 abut against the two sides of the optical glass, the optical glass is clamped between the two variable diameter blocks 31. At the same time, the variable diameter blocks 31 press the optical glass onto the vertical plate 21 to fix the optical glass and prevent it from falling off during the cleaning process. After cleaning, the rotating rod 3 is rotated in the opposite direction to gradually increase the distance between the two variable diameter blocks 31 near the vertical plate 21 until the two variable diameter blocks 31 separate from the optical glass. At this time, the cleaned optical glass can be removed.

[0021] Specifically, the operation steps for clamping the optical lens 6 using the cleaning bracket provided in this embodiment are as follows: Place the optical lens 6 on top of the two vertical plates 21 so that the optical lens 6 is positioned between the two limiting rods 22. Then, operate the driving assembly 5 to move the moving seat 4 and drive the rotating rod 3 to rotate, causing the variable diameter block 31 to rotate under the drive of the rotating rod 3 to adjust the distance between the two variable diameter blocks 31 near the vertical plates 21. Rotate the rotating rod 3 to gradually reduce the distance between the two variable diameter blocks 31 near the vertical plates 21 until the two variable diameter blocks 31 are respectively positioned with respect to the optical lens 6. The two sides of the glass abut against each other, clamping the optical glass between the two variable diameter blocks 31. Simultaneously, the variable diameter blocks 31 press the optical glass firmly against the vertical plate 21, thus fixing the optical glass and preventing it from falling during cleaning. At this point, the optical lens 6 cleaning bracket, along with the optical lens 6, can be placed into the cleaning machine for cleaning. After cleaning, the optical lens 6 cleaning bracket, along with the optical lens 6, is removed from the cleaning machine. Then, the rotating rod 3 is rotated in the opposite direction to gradually increase the distance between the two variable diameter blocks 31 near the vertical plate 21 until the two variable diameter blocks 31 detach from the optical glass. At this point, the cleaned optical glass can be removed. The optical lens 6 cleaning bracket provided in this embodiment clamps the optical lens 6 using two symmetrically arranged variable diameter blocks 31, ensuring the stable position of the optical lens 6 during cleaning and preventing it from falling and breaking due to water flow impact or vibration. Furthermore, it is simple to operate and convenient to use.

[0022] like Figure 1 and Figure 4 As shown, a plurality of supports 2 are spaced apart on the base 1, and the plurality of supports 2 are arranged in a matrix on the base 1. By setting a plurality of supports 2 on the base 1 for placing optical lenses 6 respectively, the capacity of the optical lens 6 cleaning tray can be increased, so that multiple optical lenses 6 can be placed on the optical lens 6 cleaning tray for cleaning at the same time, which is beneficial to improving the cleaning efficiency of the optical lenses 6.

[0023] In this embodiment, the base 1 is provided with a plurality of parallel rotating rods 3 at intervals. Each rotating rod 3 is provided with a plurality of symmetrical variable diameter blocks 31 at intervals, and each set of symmetrical variable diameter blocks 31 corresponds to one of the supports 2. The base 1 has a plurality of parallel rotating rods 3, and each rotating rod 3 is provided with a plurality of variable diameter blocks 31. Rotating one of the rotating rods 3 can drive the plurality of variable diameter blocks 31 to rotate synchronously and fix the optical lenses 6 placed on the supports 2 in the same row. Each rotating rod 3 is provided with a gear 32 that meshes with the rack 41. When the moving seat 4 moves, the plurality of rotating rods 3 can rotate synchronously and clamp the optical lenses 6 placed on each support 2 simultaneously, so as to facilitate batch cleaning of the optical lenses 6.

[0024] like Figure 2 and Figure 3 As shown, the support 2 also includes a mounting cylinder 23 located between the two vertical plates 21. The mounting cylinder 23 has a mounting hole that mates with the rotating rod 3. The mounting cylinder 23 is used to cooperate with the rotating rod 3 to keep the relative position of the rotating rod 3 and the support 2 stable, preventing the rotating rod 3 from moving unexpectedly and causing the variable diameter block 31 to deviate from the preset position.

[0025] Please refer to Figure 3 The variable diameter block 31 has a through hole that mates with the rotating rod 3 and a through hole that communicates with the through hole. The rotating rod 3 has a locking hole aligned with the through hole, and a screw 33 that mates with the locking hole is located in the through hole. The variable diameter block 31 is fixed to the rotating rod 3 by the engagement of the screw 33 with the locking hole. This facilitates the installation of the variable diameter block 31 onto the rotating rod 3 while ensuring that the variable diameter block 31 rotates smoothly under the drive of the rotating rod 3, which helps to improve the structural stability of the optical lens 6 cleaning bracket.

[0026] Please combine Figure 2 and Figure 4 The base 1 is provided with a dovetail groove 11, the length direction of which is consistent with the moving direction of the movable seat 4, and the movable seat 4 is provided with a slider 42 that cooperates with the dovetail groove 11. The movable seat 4 achieves a sliding connection with the base 1 through the cooperation of the slider 42 and the dovetail groove 11, so that the movable seat 4 can move smoothly on the base 1 while preventing the movable seat 4 from deviating from the preset direction.

[0027] In detail, the driving assembly 5 includes a driving screw 51 rotatably mounted on the base 1. The length direction of the driving screw 51 is consistent with the moving direction of the movable seat 4, and the movable seat 4 is provided with a threaded hole that mates with the driving screw 51. When the driving screw 51 rotates, the engagement between the driving screw 51 and the threaded hole drives the movable seat 4 to move along the axial direction of the driving screw 51. Controlling the rotation direction of the driving screw 51 can adjust the moving direction of the movable seat 4, thereby controlling the moving direction and distance of the movable seat 4, and thus precisely adjusting the rotation angle of the rotating rod 3 and ensuring that the optical lens 6 is clamped by the variable diameter block 31.

[0028] like Figure 1 and Figure 4 As shown, a waterproof cover 12 is fixedly connected to the base 1. The movable seat 4, the gear 32, and part of the drive screw 51 are located within the space enclosed by the waterproof cover 12 and the base 1. The waterproof cover 12 is used to protect the movable seat 4, the gear 32, and part of the drive screw 51, preventing the cleaning fluid in the cleaning machine from contacting the threaded parts of the rack 41, the gear 32, and the drive screw 51 during the cleaning process. This helps to improve the reliability of the bracket for cleaning the optical lens 6.

[0029] In this embodiment, a handwheel 52 is fixedly connected to one end of the drive screw 51, and the end of the drive screw 51 with the handwheel 52 extends out of the space enclosed by the base 1 and the waterproof cover 12. Operating the handwheel 52 allows for convenient rotation of the drive screw 51 and control of its rotation direction, facilitating the use of the optical lens 6 cleaning bracket.

[0030] 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.
