Description

Technical Field

[0001] This utility model relates to the field of square cylindrical mirror technology, and in particular to a cleaning fixture for square cylindrical mirrors. Background Technology

[0002] Cylindrical lenses, similar to spherical lenses, both use curved surfaces to focus or diverge light. However, cylindrical lenses only converge or diverge in one direction and do not affect light in the perpendicular direction. This is impossible with spherical lenses, as they focus or diverge light uniformly in a rotationally symmetrical manner. Cylindrical lenses, on the other hand, can focus parallel beams into a straight line, effectively reducing spherical and chromatic aberration. They are widely used in high-precision testing instruments, high-power lasers, and optical communications.

[0003] With the upgrading of the industrial chain, optical devices are becoming smaller and more compact, creating a large market for microcylinder lenses. In the field of optical communication, direct mounting technology for optical components is gradually being adopted, eliminating fixed components such as metal sleeves and optimizing functional areas. To keep pace with technological trends, a microcylinder lens has been developed. The curvature R and height H of the microcylinder lens determine its focal length (referencing the focal length formula for spherical lenses). Its four cylindrical faces are square, and the two non-C-groove faces do not need to be selected; any face can be directly mounted on the base platform (the C-groove is used to distinguish the optical functional and non-functional directions of the cylinder lens; the groove depth <0.05mm does not interfere with the optical path). The cylinder size L = the design distance between the center point of the optical path and the base * 2. To ensure that the optical path does not shift, the central axis of the optical path needs to coincide with the center line of the square cylinder, and the two sides of the cylinder should be symmetrical with the central axis of the square cylinder. This technology is applied to the Optical Circulator Module.

[0004] Using existing technology, square micro-cylindrical mirrors can be processed in the following steps: First, the cylindrical blank is thinned to a length L and a cylindrical mirror blank of the same length L is taken from the center line core, ensuring that the two sides of the cylinder are symmetrical with the central axis of the cylinder (in actual processing, there may be deviation of the center line, which needs to be checked and selected). Second, the micro-cylindrical mirror blank is cut from the inside to form a plane b. The plane b is then bonded to the polishing substrate for fixation, and the curved surface a is polished using a cylindrical surface tumbling polisher to obtain a smooth surface and shape. Third, grooves are cut into the two symmetrical cylindrical surfaces in the cylindrical mirror to distinguish the "functional direction". Fourth, the plane b is ground and polished, and the height H is controlled. Fifth, the mirror is cleaned using a conventional cleaning fixture.

[0005] This technology has drawbacks: conventional cleaning with mesh clamps can easily damage the mesh, and replacement is time-consuming and labor-intensive. In addition, ordinary cleaning clamps are not suitable for square microcylinders, and the product tends to rotate and rub against the mesh during ultrasonic cleaning, causing surface scratches.

[0006] Therefore, a cleaning fixture for square microcylindrical mirrors is still needed to solve the above problems. Utility Model Content

[0007] This invention provides a cleaning fixture for a square microcylindrical mirror that solves the above-mentioned problems.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A cleaning fixture for a square microcylinder includes a cylinder frame, an integrated mesh plate frame, and a mesh frame connected face to face in sequence.

[0010] The placement area of ​​the cylindrical lens holder has multiple evenly distributed mesh holes for the square micro cylindrical lens to pass through. The mesh holes are rectangular in shape, and the corners of the rectangular holes are provided with clearance parts to avoid the edges of the square cylindrical lens.

[0011] The integrated mesh frame has multiple drainage sections that correspond one-to-one with the mesh hole positions. These sections support the bottom of the square micropillars and allow cleaning agents to flow from the top of the square micropillars and out through the drainage sections during cleaning.

[0012] In one embodiment, the clearance portion is a cylindrical hole formed on the cross-sectional edge of the cylindrical lens frame, which includes a partially curved surface.

[0013] In one embodiment, the edge of the avoidance portion is a circular partial arc.

[0014] In one embodiment, a venting section includes a plurality of vent holes, the centers of which are located at the inflection points of the same polygon.

[0015] In one embodiment, the centers of the plurality of drainage holes are located at the inflection points of the same pentagon, and the drainage hole is located at the center of the pentagon.

[0016] In one embodiment, both the integrated mesh frame and the mesh frame of the cylindrical lens frame are provided with connection holes for fixing with bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0018] By setting multiple evenly distributed mesh holes on the cylindrical lens holder and opening clearance parts at the corners of the mesh holes, during cleaning, the clearance parts allow the liquid to flow smoothly from the surface of the square micro-cylinder lens placed in the mesh holes, preventing the square micro-cylinder lens from sliding and scratching relative to the mesh holes due to the flow of cleaning liquid. This would prevent the corners of the square micro-cylinder lens from colliding with the inner wall of the mesh holes, causing the corners to break and thus rendering the processed square micro-cylinder lens unusable.

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0025] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0026] Reference Figure 1-4 This utility model provides a cleaning fixture for a square microcylinder, including a cylinder frame 1, an integrated mesh plate frame 2, and a mesh frame 3 connected face to face in sequence.

[0027] The placement area of ​​the cylindrical lens holder 1 has multiple evenly distributed mesh holes 11 for the square micro cylindrical lens to pass through. The mesh holes 11 are rectangular holes, and the corners of the rectangular holes are provided with clearance parts 12 to avoid the edges of the square cylindrical lens.

[0028] The integrated mesh frame 2 has multiple drainage sections 21, each corresponding to a mesh hole 11, to support the bottom surface of the square microcylinder. During cleaning, the cleaning agent flows from the top of the square microcylinder and then exits through the drainage section 21. During cleaning, an adhesive layer, such as a wax layer, is formed on the sidewall of the square microcylinder. The periphery of the square microcylinder passes through the mesh hole 11 on the microcylinder frame 1, and the bottom of the square microcylinder is placed on top of the drainage hole, at its top edge. The cleaning liquid flows downwards from the top curved surface of the microcylinder, and then, under the influence of gravity, gradually flows along the surrounding sidewalls of the microcylinder, passes through the bottom of the flow channel of the clearance section 12, and finally exits through the drainage section 21. After flowing through the avoidance section 12, the cleaning agent flows smoothly out of the drain hole, preventing the square micro-cylinders from surging during flow and causing them to sway relative to each other within the mesh aperture 11. This would prevent the square micro-cylinders from scratching and colliding with the inner wall of the mesh aperture 11, resulting in broken edges or scratches. It also effectively avoids the problem of the mesh surface being easily damaged.

[0029] In one embodiment, the clearance portion 12 is a cylindrical hole formed on the cylindrical lens frame 1, with a partially curved edge. The clearance portion 12 is, for example, a hole formed on the cylindrical lens frame 1 that partially overlaps and communicates with the mesh hole 11, and has a curved arc-shaped profile. After installation, during cleaning, the sharp corners of the square micro-cylinder lens extend into the clearance portion 12. The arc-shaped profile of the hole effectively prevents the edge from directly colliding with the inner wall of the cylindrical hole during shaking, thus avoiding damage.

[0030] Preferably, the edge of the avoidance portion 12 is a circular arc. The avoidance portion 12 has an arc-shaped outline, and the two ends of the arc are located on the two adjacent edges of the rectangular hole, respectively. This regular shape of the avoidance portion 12 can effectively avoid the corner collision damage of the square microcylindrical lens.

[0031] Preferably, one of the drainage sections 21 includes multiple drainage holes, the centers of which are located at the inflection points of the same polygon. The inner diameter of each drainage hole is smaller than the bottom surface area of ​​the square microcylindrical mirror, serving to support the bottom of the square microcylindrical mirror and allowing the cleaning agent to flow smoothly during cleaning, preventing the square microcylindrical mirror from shaking.

[0032] Preferably, the centers of the plurality of drainage holes are located at the inflection points of the same pentagon, and a drainage hole is also located at the center of the pentagon. The plurality of drainage holes are of equal size and are distributed in a pentagonal pattern, which facilitates the flow of cleaning agent from the periphery of the square microcylinder during cleaning, thereby ensuring that the square microcylinder remains stably within the mesh plate holes 11.

[0033] Preferably, the centers of the plurality of drainage holes are located at the inflection points of the same pentagon, and a drainage hole is also located at the center of the pentagon. The even distribution of the six drainage holes ensures smooth flow of the micro-cleaning agent.

[0034] Preferably, the cylindrical lens frame 1, the integrated mesh panel frame 2, and the mesh frame 3 are all provided with connecting holes 4 for bolts 5 to pass through and fix the outer nuts 6. Connecting them into a whole can effectively improve the overall coordination and prevent the panels and frames from sliding against each other.

[0035] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
