Description

Technical Field

[0001] This utility model relates to the field of optical device manufacturing technology, and in particular to a lens cleaning tool for optical devices. Background Technology

[0002] Optical components in optical communication devices connect to optical fibers at one end and to the circuit board of the device at the other end via pins. These components require processes such as end cap soldering and pin bending. During handling and processing, a certain amount of dust adheres to the optical elements. This dust affects the light propagation effect after the connection between the optical component and the optical fiber. Therefore, the optical elements need to be cleaned after each operation. Current cleaning methods involve spraying cleaning agents such as alcohol onto the optical elements, but this method suffers from uncontrollable cleaning effectiveness. Utility Model Content

[0003] This invention provides a lens cleaning tool for optical devices, which overcomes the shortcomings of the prior art and solves the problem of uncontrollable cleaning effect of existing cleaning methods, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A lens cleaning tool for optical devices includes a tube with a connector at one end. The connector has a movable hole inside, and a tapered hole at the lower end of the movable hole. The upper end of the tapered hole is a small end, and a round hole is formed at the lower end of the tapered hole. A rubber cup is provided at the other end of the connector, covering the round hole and sealing it to the connector. The rubber cup has multiple holes. A lint-free cloth is provided around the connector and the rubber cup, and the lint-free cloth is tightly attached to the outer periphery of the connector and the rubber cup through a ring. A pull rod is inserted inside the tube, and a tapered head is threaded to the lower end of the pull rod. An end post is provided at the lower end of the tapered head. Both the end post and the tapered head are made of rubber. The pull rod passes through the movable hole, and the end post and the tapered head move within the tapered hole and the round hole. The rubber cup, round hole, and conical hole form a cavity for holding cleaning agents such as alcohol. When cleaning fine dust, pressing the tool deforms the rubber cup, causing the lint-free cloth on its outer wall to adhere tightly to the optical element. During pressing, alcohol is squeezed out from the holes, thus wetting the lint-free cloth and preventing it from scratching the optical element. It also helps to adsorb fine dust onto the cloth, significantly improving the cleaning effect on the optical element. The conical head and pull rod facilitate the suction of alcohol into the cavity. Furthermore, for easy replacement of the lint-free cloth, it is secured to the connector head with a ring.

[0006] Furthermore, the upper end of the movable hole is provided with an internal threaded hole, and the lower end of the pipe fitting is provided with a threaded head. The threaded head is connected to the internal threaded hole by a thread. This detachable connection method facilitates cleaning operations inside the pipe fitting.

[0007] Furthermore, the upper end of the connector is formed with an upper extension sleeve, which is fitted onto the pipe fitting to improve the connection stability between the pipe fitting and the connector.

[0008] Furthermore, the upper outer periphery of the connector is formed with a raised edge, the lower end of the raised edge has a tapered structure, the outer periphery of the raised edge is formed with threads, the upper end of the ring is formed with a threaded ring, the threaded ring is connected to the raised edge by threads, and the inner periphery of the ring abuts against the outer side of the cleanroom cloth, so that the inner wall of the cleanroom cloth abuts against the outer periphery of the connector. The ring is connected to the connector by the threaded ring, so as to fix the cleanroom cloth and replace the cleanroom cloth in a timely manner.

[0009] Furthermore, the upper end of the fitting is formed with an end ring, and a spring is sleeved on the pull rod. The lower end of the spring abuts against the end ring. The upper end of the pull rod is fixed with a connecting sleeve by a pin. The upper end of the connecting sleeve is provided with an end cap. The upper end of the spring abuts against the inner wall of the end cap. The spring ensures the suction capacity of the conical head and end column for alcohol.

[0010] The advantages of the above technical solution are:

[0011] This invention facilitates the removal of micro-dust from optical components on optical devices. By using a wetting and adhesion method, it can prevent damage to the optical components while improving the micro-dust removal effect. Attached Figure Description

[0015] Figure 3 A cross-sectional view of the connector is shown. Detailed Implementation

[0016] like Figures 1-3As shown, a lens cleaning tool for optical devices includes a tube 1, one end of which is connected to a connector 2. The connector 2 has a semi-ellipsoidal structure with a protruding end. The connector 2 has a movable hole 36 inside, the lower end of which connects to a conical hole 37. The upper end of the conical hole 37 is a smaller end, and the lower end of the conical hole 37 has a circular hole 22. The other end of the connector 2 has a rubber cup 24, which covers the circular hole 22 and is sealed and fixed to the connector 2. The rubber cup 24 has multiple holes 25. A lint-free cloth 28 is provided around the connector 2 and the rubber cup 24, and the lint-free cloth 28 is tightly attached to the outer periphery of the connector 2 and the rubber cup 24 via a ring 27. A pull rod 34 is inserted inside the pipe fitting 1. A tapered head 35 is connected to the lower end of the pull rod 34. An end post is provided at the lower end of the tapered head 35. Both the end post and the tapered head 35 are made of rubber. The pull rod 34 is inserted into the movable hole 36, and the end post and the tapered head 35 move within the tapered hole 37 and the round hole 22.

[0017] Specifically, the upper end of the movable hole 36 is provided with an internal threaded hole 38, the lower end of the pipe fitting 1 is provided with a threaded head 29, the threaded head 29 is connected to the internal threaded hole 38 by threads, and the upper end of the connector 2 is formed with an upper extension sleeve 21, which is fitted onto the pipe fitting 1.

[0018] Specifically, the upper outer periphery of the connector 2 is formed with a raised edge 20, the lower end of the raised edge 20 is tapered, the outer periphery of the raised edge 20 is formed with threads, the upper end of the ring sleeve 27 is formed with a threaded ring 26, the threaded ring 26 is connected to the raised edge 20 by threads, and the inner periphery of the ring sleeve 27 abuts against the outer side of the cleanroom cloth 28, so that the inner wall of the cleanroom cloth 28 abuts against the outer periphery of the connector 2.

[0019] Specifically, the upper end of the pipe fitting 1 is formed with an end ring 10, a spring 32 is sleeved on the pull rod 34, the lower end of the spring 32 abuts against the end ring 10, the upper end of the pull rod 34 is fixed with a connecting sleeve 33 by a pin, the upper end of the connecting sleeve 33 is provided with an end cap 39, and the upper end of the spring 32 abuts against the inner wall of the end cap 39.

[0020] In this embodiment, when performing micro-dust removal on optical components of an optical device, the operator first wraps a clean lint-free cloth 28 around the lower end of the rubber cup 24 and the connector 2, then puts the ring 27 on the connector 2, and rotates the threaded ring 26 to connect it to the flange 20 by thread. In this way, the lint-free cloth 28 is fixed to the connector 2 by the ring 27.

[0021] Then the operator presses down on the end cap 39. During the pressing process, the end post and the conical head 35 will move downwards. Then the connector 2 will be inserted into the alcohol storage container. After that, the pressure on the end cap 39 will be released. Then the pull rod 34, the end post and the conical head 35 will move upwards under the elastic force of the spring 32. During the movement, the alcohol will be drawn into the cavity formed by the rubber cup 24, the conical hole 37 and the round hole 22 through the hole 25.

[0022] The operator then inserts the rubber cup 24 into the optical device and makes the cleanroom cloth 28 contact the optical device, and then rotates it. During the rotation, the rubber cup 24 will gradually deform, and the deformation will allow the cleanroom cloth 28 to fully contact the optical element. After rotating several times, the connector 2 is removed. The rotation can fully and comprehensively adhere micro-dust to the cleanroom cloth 28.
