Double-sided adhesive tape is adhered to the upper end of the dustproof head to adsorb and fix the dust on it, preventing it from falling onto the optical element.

Description

Technical Field

[0001] This utility model relates to the field of optical device processing technology, and in particular to a placement disk. Background Technology

[0002] Optical devices are key components in optical modules used to connect optical fibers and signal input / output systems. For example... Figure 4 A three-dimensional structural diagram of an optical device is shown. As can be seen from the figure, the optical device includes a housing 4, an optical element 42 is provided at the lower end of the interior of the housing 4, a convex ring 40 is provided at the upper outer periphery of the upper end of the housing 4, and multiple pins 41 are provided at the upper end of the housing 4.

[0003] Optical element 42 is prone to dust contamination during processing and transfer, which can significantly affect the transmission of optical signals. To improve quality, multiple microscopic inspections are often performed to ensure that optical element 42 is free of dust. Currently used transfer trays reduce dust contamination by placing the optical device upside down, with the pins facing upwards. However, the trays themselves are prone to dust contamination. Therefore, during transfer, dust from the recesses of the tray can easily drift onto the optical element 42, resulting in dust contamination on the optical element. Utility Model Content

[0004] This invention provides a placement tray to overcome the shortcomings of the prior art and solve the problem that optical elements are easily contaminated with dust during transfer, thus having strong practicality.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0006] A placement disk includes a rectangular disk body with multiple limiting mechanisms fixed in an array on the rectangular disk body, and an optical device is placed on the limiting mechanisms.

[0007] Furthermore, the two ends of the rectangular disc are bent upwards to form side plates, and gripping holes are provided on the side plates.

[0008] Furthermore, the limiting mechanism includes a ring fixed to the rectangular disc by screws, an upper extension tube formed on the ring, a limiting ring at the upper end of the upper extension tube, a movable tube movably disposed inside the limiting ring, the lower end of the movable tube being closed, a spring at the lower end of the movable tube, the lower end of the spring abutting against the rectangular disc, and a dustproof head at the lower end of the inner side of the movable tube.

[0009] Furthermore, the upper end of the dustproof head has a conical structure, and the upper end of the dustproof head is the smaller end.

[0010] Furthermore, the dust cover is made of rubber and has double-sided tape attached to its top.

[0011] Furthermore, the lower end of the movable tube is formed with a ring, and the spring is located inside the ring.

[0012] Furthermore, a concave seat is fixed to the limiting ring by screws. A connecting shaft is rotatably provided at the upper end of the concave seat. A vertical plate is rotatably provided on the connecting shaft. A clamping plate is formed on the inner wall of the upper end of the vertical plate. A vertical end plate is formed on the outer end of the concave seat. An inclined plate is bent outward at the upper end of the vertical end plate. A V-shaped spring is installed on the inclined plate by screws. The other end of the V-shaped spring abuts against the outer wall of the vertical plate.

[0013] Furthermore, a protruding plate is provided at the upper end of the vertical plate.

[0014] The advantages of the above technical solution are:

[0015] This invention uses a movable tube to limit the lower end of the optical device's casing, thereby preventing dust from entering the optical elements at the lower end of the casing during the transfer process.

[0016] This invention uses a dustproof head to seal the lower end of the tube shell, preventing dust from entering the tube shell during transfer. There is a gap between the upper end of the dustproof head and the optical element, which prevents dust on the dustproof head from adhering to the optical element. In order to adsorb and fix the dust on the dustproof head and prevent it from falling onto the optical element, double-sided tape is attached to its upper end.

[0017] This invention uses a locking plate that can be locked onto the upper surface of the convex ring to fix the tube shell in place, thus preventing the tube shell from moving or falling off during transfer. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0020] Figure 2 A three-dimensional structural diagram of the limiting mechanism is shown.

[0021] Figure 3 A cross-sectional view of the limiting mechanism is shown.

[0022] Figure 4 A three-dimensional structural diagram of the optical device is shown. Detailed Implementation

[0023] like Figures 1-4 As shown, a placement disk includes a rectangular disk body 1, on which multiple limiting mechanisms 2 are fixed in an array, and optical devices are placed on the limiting mechanisms 2.

[0024] The rectangular disc 1 has side plates 10 formed by bending upwards at both ends, and the side plates 10 have gripping holes 11.

[0025] The limiting mechanism 2 includes a ring 20 fixed to a rectangular disc 1 by screws. An upper extension tube 21 is formed on the ring 20. A limiting ring 22 is provided at the upper end of the upper extension tube 21. A movable tube 34 is movably provided inside the limiting ring 22. The lower end of the movable tube 34 is closed. A spring 32 is provided at the lower end of the movable tube 34. The lower end of the spring 32 abuts against the rectangular disc 1. A dustproof head 35 is provided at the lower end of the movable tube 34. The upper end of the dustproof head 35 has a conical structure and is the smaller end. The dustproof head 35 is made of rubber and has double-sided tape pasted on its upper end. Operators need to replace the double-sided tape pasted on the dustproof head 35 regularly. A ring sleeve 33 is formed at the lower end of the movable tube 34, and the spring 32 is located inside the ring sleeve 33.

[0026] A concave seat 23 is fixed to the limiting ring 22 by screws. A connecting shaft 24 is rotatably provided at the upper end of the concave seat 23. A vertical plate 26 is rotatably provided on the connecting shaft 24. A protruding plate 27 is provided at the upper end of the vertical plate 26. A retaining plate 28 is formed on the inner wall of the upper end of the vertical plate 26. A vertical end plate 29 is formed at the outer end of the concave seat 23. An inclined plate 30 is bent outward at the upper end of the vertical end plate 29. A V-shaped spring piece 31 is installed on the inclined plate 30 by screws. The other end of the V-shaped spring piece 31 abuts against the outer wall of the vertical plate 26.

[0027] In this embodiment, the operator inserts the lower end of the housing 4 of the optical device one by one onto the dustproof head 35. After insertion, the dustproof head 35 extends into the lower end of the housing 4, with the upper end of the dustproof head 35 a certain distance away from the optical element 42. The lower end of the housing 4 abuts against the bottom of the movable tube 34, and then the movable tube 34 is pressed down to deform the spring 32. Before insertion, the clamping plate 28 is rotated outward to avoid interfering with the placement of the housing 4. During the rotation, the V-shaped spring 31 deforms. After placement, the V-shaped spring 31 causes the clamping plate 28 to rotate inward, making the vertical plate 26 vertical. Then, the elastic force provided by the spring 32 can move the housing 4 upward, so that the lower wall of the clamping plate 28 abuts against the upper surface of the convex ring 40. This ensures the fixed and limited effect of the housing 4, preventing the housing 4 from jumping up and down during transfer.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
