Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and more specifically to a cleaning fixture for optical lenses. Background Technology

[0002] In ultrasonic cleaning of optical lenses, vertical insertion-type mounting racks are widely used due to their high space utilization and ease of batch processing. However, for convex and biconvex lenses, existing technologies have the following significant drawbacks:

[0003] The vertical insertion placement rack has a core structure of metal support. It uses plastic retaining grooves to vertically fix the lens in the cleaning tank. When the curved edge of the convex lens comes into contact with the retaining structure of the rack, the large curvature of the surface can cause direct contact between the lens and the retaining component. Under the high-frequency vibration of ultrasonic waves, this contact intensifies the friction between the lens and the rack, leading to surface scratches, coating peeling, or micro-cracks at the edges. This damage directly affects image quality, especially when cleaning high-precision optical lenses. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning fixture for optical lenses to avoid friction and collision between the lens surface and the fixture.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A cleaning fixture for optical lenses includes a hanging plate with a through groove. A lens clamping assembly is disposed in the through groove. The lens clamping assembly includes a horizontally symmetrically rotatable shaft within the through groove. A mounting plate is fixedly connected to the shaft. An arc-shaped metal clamping bracket is fixedly connected to the bottom of the mounting plate. Two arc-shaped metal clamping brackets are symmetrically arranged. A base plate is disposed between the two mounting plates. The base plate is fixedly connected to the through groove. A guide rod is vertically disposed on the base plate. A slide block is slidably fitted on the guide rod. Connecting plates are provided between the two sides and the mounting plate. The two ends of the connecting plates are rotatably connected to the top of the mounting plate and the end of the slide, respectively. A first spring is connected between the bottom of the slide and the base plate. An adjusting plate is provided above the slide. An adjusting nut is fixedly connected to the top of the adjusting plate. The top of the guide rod has an external thread. The adjusting nut is threaded to the top of the guide rod. A top plate is rotatably provided coaxially at the bottom of the adjusting plate. Both the top plate and the adjusting plate are slidably sleeved on the guide rod. A second spring is connected between the top plate and the slide.

[0007] Furthermore, multiple sets of the through slots and lens clamping components are provided, and the through slot array is distributed on the hanging plate.

[0008] Furthermore, mounting holes are provided on the hanging plate.

[0009] Furthermore, a suspension frame is fixedly connected to the top of the suspended platform.

[0010] Furthermore, a silicone anti-slip sleeve is provided on the outer side of the arc-shaped metal clamping frame.

[0011] Furthermore, the adjusting nut is a nylon insert locking nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model adopts a symmetrically arranged arc-shaped metal clamping frame that only contacts the edge of the lens, completely avoiding the optical convex surface of the biconvex lens. This fundamentally eliminates friction and collision between the lens and the fixture, solving the core problem of easy scratching of the convex lens surface in the prior art. Through the combined design of the first and second springs, the slide can automatically adjust the opening and closing range according to the lens diameter. With the precise control of the spring preload by the adjusting nut, stable clamping of lenses of different diameters can be achieved, avoiding lens drop due to insufficient clamping force or edge damage due to excessive clamping force.

[0019] like Figures 1 to 4As shown, a cleaning fixture for optical lenses includes a hanging plate 1 with a through groove 101. A lens clamping assembly is disposed in the through groove 101. The lens clamping assembly includes a horizontally symmetrically rotatable shaft 2 within the through groove 101. A mounting plate 3 is fixedly connected to the shaft 2. An arc-shaped metal clamping frame 4 is fixedly connected to the bottom of the mounting plate 3. Two arc-shaped metal clamping frames 4 are symmetrically arranged. A base plate 5 is disposed between the two mounting plates 3. The base plate 5 is fixedly connected to the through groove 101. A guide rod 6 is vertically disposed on the base plate 5. A sliding seat 7 is slidably sleeved on the guide rod 6. A connecting plate 8 is provided between the side and the mounting plate 3. The two ends of the connecting plate 8 are rotatably connected to the top of the mounting plate 3 and the end of the slide block 7, respectively. A first spring 9 is connected between the bottom of the slide block 7 and the base plate 5. An adjusting plate 10 is provided above the slide block 7. An adjusting nut 11 is fixedly connected to the top of the adjusting plate 10. The top of the guide rod 6 is provided with an external thread. The adjusting nut 11 is threadedly connected to the top of the guide rod 6. A top plate 12 is rotatably provided at the bottom of the adjusting plate 10. Both the top plate 12 and the adjusting plate 10 are slidably sleeved on the guide rod 6. A second spring 13 is connected between the top plate 12 and the slide block 7.

[0020] Multiple sets of the through slots 101 and the lens clamping assembly are provided, and the through slots 101 are arrayed on the hanging plate 1.

[0021] The hanging plate 1 has a mounting hole 102; the mounting hole 102 on the hanging plate 1 facilitates the connection between the fixture and the robotic arm, and the robotic arm suspends the fixture and immerses it in the cleaning solution of the cleaning tank.

[0022] The top of the hanging plate 1 is fixedly connected to a suspension frame 14; the suspension frame 14 allows the fixture to be directly suspended above the cleaning tank, simplifying the installation process and facilitating the overall hoisting and transportation of the fixture, thus improving operational convenience.

[0023] The outer side of the arc-shaped metal clamp 4 is provided with a silicone anti-slip sleeve; the elastic buffer and increased friction of the silicone anti-slip sleeve further protect the lens edge from clamping stress damage, while enhancing the clamping reliability under ultrasonic vibration and preventing the lens from sliding.

[0024] The adjusting nut 11 is a nylon insert locking nut; the nylon insert locking nut utilizes the elastic clamping force of the insert to effectively prevent the adjusting nut 11 from loosening in the ultrasonic high-frequency vibration environment, ensuring the long-term stability of the clamping force setting value and avoiding the risk of clamping failure due to nut loosening.

[0025] Working principle:

[0026] In the initial state, the slide 7 is stably mounted on the guide rod 6 under the action of the first spring 9 and the second spring 13, and the two arc-shaped metal clamps 4 on both sides tend to close under the action of the mounting plate 3. When the lens is vertically inserted between the two arc-shaped metal clamps 4 from below, the edge of the lens pushes the arc-shaped metal clamps 4 to rotate outward around the pivot 2, and drives the slide 7 to slide downward along the guide rod 6 through the connecting plate 8. The first spring 9 is compressed and the second spring 13 is stretched, forming an elastic clamping force to clamp the edge of the lens.

[0027] By rotating the adjusting nut 11, the adjusting plate 10 can be moved up and down, changing the compression of the first spring 9 and the initial compression of the second spring 13, adjusting the initial position of the slide 7, thereby adjusting the preload of the clamping mechanism to adapt to lenses of different diameters.

[0028] This utility model features an edge-clamping design that completely avoids contact with convex surfaces, making it suitable for high-precision cleaning of biconvex lenses. The double-spring elastic buffer and silicone anti-slip sleeve effectively cope with ultrasonic vibrations, preventing the lenses from shifting and falling off during vibration.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
