Description

Technical Field

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

[0002] In modern optics, cleaning optical lenses is a critical step in ensuring their performance and quality. Optical lenses are widely used in various high-precision devices, such as camera lenses, telescopes, microscopes, and lasers. These applications require extremely high levels of lens cleanliness; even the smallest stain or residue can affect image quality, optical transmission efficiency, or the overall performance of the equipment.

[0003] Traditional lens cleaning methods typically involve ultrasonic cleaners. However, different types of contaminants (such as dust, oil, and chemical residues) require different cleaning methods and solutions. A single cleaning step is unlikely to achieve the desired cleaning effect. Therefore, multi-stage cleaning has become an effective solution. Multi-stage cleaning uses different types of cleaning solutions in multiple compartments to gradually remove various contaminants from the lenses, ensuring that a very high level of cleanliness is ultimately achieved.

[0004] While multi-stage cleaning systems are widely used in existing optical lens cleaning equipment, significant shortcomings remain in lens repositioning. Specifically:

[0005] 1. Existing equipment typically relies on manual labor to move frames containing lenses from one compartment to another. This manual operation is not only time-consuming but also prone to interrupting the production process, failing to meet the high-efficiency requirements of mass production.

[0006] 2. During manual operation, operators may make mistakes such as inaccurate positioning or improper frame placement, affecting the consistency of cleaning results. Especially when handling high-precision optical lenses, any slight deviation may lead to incomplete cleaning or lens damage.

[0007] 3. During the manual repositioning of the frame, operators' gloves, tools, etc., may introduce new contaminants, reducing the cleaning effectiveness. Furthermore, frequent manual intervention increases the risk of cross-contamination. Utility Model Content

[0008] To overcome the aforementioned shortcomings, the technical problem of this utility model is to provide an ultrasonic cleaning device for optical lenses.

[0009] The technical solution of this utility model is as follows: an ultrasonic cleaning device for optical lenses, comprising an ultrasonic cleaner, a motor, a rotating frame, locking pins, a U-shaped track, a movable frame, torsion springs, and brackets. The ultrasonic cleaner has four compartments, each containing a tray. A motor is symmetrically mounted on the front of the ultrasonic cleaner, and a rotating frame is connected to the output shaft of each motor. A U-shaped track is symmetrically connected to the front of the ultrasonic cleaner. Two locking pins are connected to the left and right ends of the movable frame. The movable frame is slidably connected to the U-shaped track via the two locking pins. The movable frame is located at the top of the ultrasonic cleaner. The rotating frame is slidably connected to adjacent locking pins. Four sets of brackets are rotatably connected to the rear of the movable frame, with two brackets in each set. Each set of brackets is located on both sides of the compartment and symmetrically distributed. Two torsion springs are connected between each bracket and the movable frame.

[0010] Preferably, the frame is a frame with a border, the width of which is greater than the width of the frame, to ensure that the bracket can support the border of the frame.

[0011] Preferably, it also includes a second electric push rod, a lifting frame and a concave rod. The second electric push rod is symmetrically installed on the left and right sides of the front of the movable frame. The lifting frame is connected between the two second electric push rods and the telescopic rod. Four sets of concave rods are connected in a straight line on the lifting frame. There are two concave rods in each set, and they are aligned with the bracket on the same side. The lower end of the concave rod is provided with a concave groove, which contacts and engages with the bracket.

[0012] Preferably, the device also includes guide rods, springs, and a placement plate. Each of the four guide rods is slidably connected in a rectangular shape on the support plate. The top of each of the four guide rods is connected to a placement plate. The bottom of the placement plate is connected to the support plate, and the springs are sleeved on the guide rods.

[0013] Preferably, the device also includes a fixing plate, a first electric push rod, and a connecting frame. Two fixing plates are connected to the left and right sides of the rear of the ultrasonic cleaner. A first electric push rod is installed between each of the two corresponding fixing plates. A connecting frame is connected between the telescopic rods of the first electric push rods. The connecting frame is connected to the four support plates.

[0014] As a preferred option, a shelf is also included, with a shelf installed on the left side of the ultrasonic cleaner.

[0015] Beneficial effects: 1. Through precise control of the motor and the second electric push rod, the automatic conveying and switching of the lens-containing frame between the compartments is realized, which greatly reduces the need for manual operation, improves work efficiency, and the equipment can continuously process lenses in multiple compartments, ensuring the smooth progress of the production process. The automation system not only improves production efficiency, but also reduces human error and ensures the consistency and reliability of the cleaning process.

[0016] 2. Different types of cleaning solutions are injected into the four compartments to gradually remove various contaminants from the lenses, including dust, oil, and chemical residues. This multi-stage cleaning method ensures that the lenses achieve extremely high cleanliness. It also utilizes ultrasonic vibration technology to deeply clean the tiny particles and stubborn stains on the lens surface, providing a more thorough cleaning effect.

[0017] 3. The first electric push rod drives the tray and the placement plate to vibrate slightly up and down through the connecting frame, which increases the contact area between the lens and the cleaning solution, significantly improves the cleaning quality, ensures that the cleaning solution can evenly cover the lens surface, and further enhances the cleaning effect.

Detailed Implementation

[0023] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0024] Example: An ultrasonic cleaning device for optical lenses, such as... Figure 1 , Figure 3 and Figure 4As shown, the ultrasonic cleaner includes an ultrasonic cleaner 1, a motor 10, a rotating frame 11, locking posts 12, a U-shaped track 13, a movable frame 14, a torsion spring 19, and a bracket 20. The ultrasonic cleaner 1 has four compartments, each containing a tray 6. A perforated frame holding a lens is placed on the tray 6 for ultrasonic cleaning. Motors 10 are symmetrically mounted on the front left and right sides of the ultrasonic cleaner 1. Rotating frames 11 are welded to the output shafts of the motors 10. U-shaped tracks 13 are symmetrically welded to the front left and right sides of the ultrasonic cleaner 1. Two locking posts 12 are connected to the left and right ends of the movable frame 14. The movable frame 14 is slidably connected to the U-shaped track 13 via the two locking posts 12. The movable frame 14 is located within the ultrasonic cleaner. At the top of the acoustic cleaner 1, the rotating frame 11 is slidably connected to the adjacent locking posts 12. By rotating the rotating frame 11, the locking posts 12 and the moving frame 14 can be moved along the track of the U-shaped track 13. The rear of the moving frame 14 is rotatably connected to four sets of brackets 20. Each set of brackets 20 consists of two brackets, and each set of brackets 20 is located on both sides of the compartment and is symmetrically distributed. Two torsion springs 19 are connected between the brackets 20 and the moving frame 14. The frame is a frame with a frame, and the width of the frame is greater than the width of the frame to ensure that the brackets 20 can support the frame frame. Each set of brackets 20 can support the frame containing the lens to lift the frame upward and change the position of the frame.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a second electric push rod 15, a lifting frame 16, and concave rods 17. The second electric push rods 15 are symmetrically installed on the front side of the movable frame 14 by bolts. The lifting frame 16 is connected between the telescopic rods of the two second electric push rods 15. Four sets of concave rods 17 are connected in a straight line on the lifting frame 16. There are two concave rods 17 in each set, and they are aligned with the brackets 20 on the same side. The lower end of the concave rod 17 is provided with a concave groove. The concave groove contacts and engages with the bracket 20. In the initial state, the lower end of the concave groove supports the bracket 20, ensuring that the bracket 20 cannot rotate downward. When the concave rod 17 moves downward alone, it can push the bracket 20 downward through the upper end of the concave groove, changing its state.

[0026] like Figure 2 As shown, it also includes guide rods 7, springs 8 and placement plates 9. Four guide rods 7 are rectangularly slidably connected to the support plate 6. The top of each of the four guide rods 7 is connected to a placement plate 9. Four springs 8 are connected between the bottom of the placement plate 9 and the support plate 6. The springs 8 are sleeved on the guide rods 7. The frame for storing the lens is placed on the placement plate 9 and is buffered by the cooperation of the placement plate 9 and the springs 8.

[0027] The ultrasonic cleaner 1 has four compartments, each filled with a different type of cleaning solution to gradually remove various contaminants from the lenses, achieving multi-stage cleaning and ensuring lens cleanliness. The lens-containing frame is placed on a placement plate 9 within each compartment, with springs 8 acting as a buffer to ensure frame stability and prevent lens damage. Upon starting the ultrasonic cleaner 1, ultrasonic vibrations are transmitted through the cleaning solution to the lens surface, effectively removing tiny particles and stains. When the frame needs to be moved from one compartment to the next, the motor 10 is activated. The output shaft of the motor 10 rotates, driving the rotating frame 11 to rotate. The rotating frame 11 first pushes the locking pin 12 upwards along the vertical track on the right side of the U-shaped track 13. The locking pin 12 then drives the moving frame 14 and the bracket 20 to rise synchronously, subsequently driving the second electric push rod 15, the lifting frame 16, and the concave rod 1... 7. Move upwards, the concave groove of the concave rod 17 abuts against the bottom surface of the bracket 20. The upward movement of the bracket 20 can lift the frame containing the lens upwards, so that it is separated from the placement plate 9. After being lifted, the rotating frame 11 continues to rotate, so that the locking post 12 passes through the bend of the U-shaped track 13, and then drives the frame to move straight to the left until it is aligned with the next compartment. After the frame is aligned, the rotating frame 11 continues to rotate, pushing the locking post 12 to move downwards along the left vertical track of the U-shaped track 13, so that the moving frame 14, bracket 20, second electric push rod 15, lifting frame 16 and concave rod 17 descend synchronously, and finally place the frame on the placement plate 9 of the next compartment. After the leftmost frame has completed the cleaning of all four compartments, it is removed from the ultrasonic cleaner 1, ready for subsequent processing or removal. The remaining frames continue to move to the left in sequence and enter the next compartment for cleaning.

[0028] After the frame position is changed, the movable frame 14 needs to be reset to prepare for the next operation. First, start the second electric push rod 15 to extend its telescopic rod, which drives the lifting frame 16 and the concave rod 17 to move downward. The upper end of the concave groove of the concave rod 17 will push the bracket 20 to rotate downward and into a vertical state, so that it no longer supports the frame. At the same time, the torsion spring 19 deforms, and the concave rod 17 maintains this height. Control the motor 10 to run in the opposite direction, which drives the rotating frame 11 to move in the opposite direction along the U-shaped track 13, so that the locking post 12, the movable frame 14 and the bracket 20 return to the initial position along the original trajectory. The second electric push rod 15, the lifting frame 16 and the concave rod 17 move synchronously, keeping the concave rod 17 against the bracket 20. The system ensures that the bracket 20 is detached from the frame without affecting its placement in the compartment. When the moving frame 14 returns to its initial position, the bracket 20 also returns to its original compartment. At this time, the telescopic rod of the second electric push rod 15 is shortened, driving the lifting frame 16 and the concave rod 17 to rise, causing the upper end face of the concave groove on the concave rod 17 to separate from the bracket 20. The torsion spring 19 rebounds and resets, and the bracket 20 reverses and returns to the horizontal state. The bracket 20 will support the frame in the compartment, while the concave rod 17 returns to its initial height, and the lower end face of the concave groove abuts against the bottom surface of the bracket 20 again, ensuring that the bracket 20 remains in the horizontal state and is ready for the next use. In this way, the frame can be automatically transported and the compartment can be switched.

[0029] like Figure 1 and Figure 2 As shown, it also includes a fixed plate 3, a first electric push rod 4 and a connecting frame 5. Two fixed plates 3 are welded to the left and right sides of the rear of the ultrasonic cleaner 1. A first electric push rod 4 is installed between the corresponding two fixed plates 3. A connecting frame 5 is connected between the telescopic rods of the first electric push rod 4. The connecting frame 5 is connected to four support plates 6 to drive the support plates 6 to rise and fall.

[0030] During the lens cleaning process, the first electric push rod 4 is activated, and the telescopic rod of the first electric push rod 4 is controlled to rise and fall at a uniform speed. This drives the tray 6 to rise and fall, which in turn drives the frame containing the lens to move up and down slightly through the placement plate 9. This increases the contact area between the lens and the cleaning solution, improving the cleaning quality of the lens. After cleaning is completed, the first electric push rod 4 is turned off.

[0031] like Figure 1 As shown, it also includes a storage plate 2. The storage plate 2 is bolted to the left side of the ultrasonic cleaner 1. After the lens is cleaned with four kinds of cleaning solutions, it is lifted from the leftmost compartment and moved to the storage plate 2 for temporary storage, so that the operator can remove the frame from the storage plate 2.

Therefore, the scope of this invention should be limited only by the appended claims.
