Description

Technical Field

[0001] This utility model relates to the field of fiber optic collimator manufacturing technology, specifically to a collimator lens assembly fixture. Background Technology

[0002] An optical fiber collimator is a passive optical device consisting of a pigtail and a self-focusing lens precisely positioned together. It can convert transmitted light within an optical fiber into parallel light (collimated light), or couple external parallel (approximately parallel) light into a single-mode optical fiber, playing a crucial role in optical fiber communication. Currently, in the assembly of optical fiber collimators, workers typically manually install the lens inside the glass tube, resulting in relatively low assembly efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a highly efficient collimator lens assembly fixture.

[0004] To achieve the above objectives, the present invention provides the following technical solution.

[0005] A collimator lens assembly fixture includes a U-shaped base and an assembly plate, with the assembly plate fixed to the U-shaped base. A positioning base plate is provided on the inner side of the U-shaped base, and the U-shaped base is slidably mounted on the positioning base plate along its width. A positioning surface is provided on the side of the positioning base plate facing the assembly plate. A rotating shaft is rotatably mounted through and on the U-shaped base, and the rotating shaft is rotatably fitted onto a pin. A mounting hole is provided on the side of the positioning base plate facing away from the assembly plate, and the pin is fixed in the mounting hole. The outer circumferential surface of the rotating shaft is threadedly connected to the U-shaped base. Along the axial direction of the pin, the rotating shaft and the pin are relatively fixed. A stop strip and double-sided adhesive are provided on the upper side of the assembly plate, with the double-sided adhesive located on the side of the stop strip facing away from the positioning base plate, and the stop strip being higher than the double-sided adhesive.

[0006] Therefore, by using double-sided adhesive and stop strips, multiple glass tubes can be quickly positioned and fixed simultaneously. By turning the rotating shaft, the assembly plate can be moved, adjusting the depth of the lens insertion into the glass tube and thus controlling the length of the lens tip extending from the front of the glass tube. This allows for the simultaneous assembly of multiple workpieces, improving assembly efficiency. Furthermore, the double-sided adhesive fixing method is simple in structure, low in cost, easy to operate, and does not damage the glass tube, resulting in good performance. After the lens is inserted into the glass tube to the predetermined depth, UV-curing adhesive is applied to the gap between the lens and the glass tube. After initial curing by ultraviolet light, the glass tube, along with the lens, can be removed and placed on the UV curing station for deep UV curing. This effectively ensures the reliability of lens positioning and improves production efficiency.

[0007] Furthermore, slide rails are installed on both inner walls of the U-shaped base, and sliders are installed on both sides of the positioning base along its length, with the sliders matching the slide rails.

[0008] Furthermore, positioning blocks are provided on both sides of the outer surface of the assembly plate along its length.

[0009] Furthermore, a knob is mounted on the outer surface of the shaft, and a rubber sleeve is provided on the outer surface of the knob.

[0010] Furthermore, the U-shaped base, assembly plate, and positioning base plate all have a symmetrical structure.

[0011] Furthermore, both ends of the assembly plate along its length are connected to the U-shaped seat by bolts.

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

[0013] This invention uses double-sided adhesive and stop bars to simultaneously fix and position multiple glass tubes. By turning the rotating shaft to move the positioning base plate, the depth of the lens insertion into the glass tube is adjusted, thereby controlling the length of the lens tip extending from the front end of the glass tube. Therefore, it can realize the simultaneous assembly of multiple workpieces and improve assembly efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0023] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0024] Please see Figures 1-4 This utility model provides a collimator lens assembly fixture, including a U-shaped base 100 and an assembly plate 101, with the assembly plate 101 fixed on the U-shaped base 100. A positioning base plate 106 is provided on the inner side of the U-shaped base 100, and the U-shaped base 100 is slidably mounted on the positioning base plate 106 along its width direction 1. A positioning surface 108 is provided on the side of the positioning base plate 106 facing the assembly plate 101. A rotating shaft 104 is rotatably mounted through and connected to the U-shaped base 100, and the rotating shaft 104 is rotatably fitted onto a pin 105. A mounting hole 107 is provided on the side of the positioning base plate 106 facing away from the assembly plate 101, and the pin 105 is fixed in the mounting hole 107. The outer peripheral surface 109 of the rotating shaft 104 is threadedly connected to the U-shaped base 100. Along the axial direction of the pin 105, the rotating shaft 104 and the pin 105 are relatively fixed. The upper side of the assembly plate 101 is provided with a baffle 102 and double-sided adhesive 103. The double-sided adhesive 103 is located on the side of the baffle 102 that faces away from the positioning substrate 106, and the baffle 102 is higher than the double-sided adhesive 103.

[0025] In use, the worker first inserts the lens 01 into the glass tube 02, then sequentially attaches multiple glass tubes 02 containing the lens 01 to the double-sided tape 103 for positioning and fixation. During the attachment process, one side of the glass tube 02 abuts against the retaining strip 102 to achieve positioning of the glass tube 02. Next, the rotating shaft 104 is turned, which moves the assembly plate 101 forward through the U-shaped seat 100. This causes the positioning surface 108 to simultaneously push multiple lenses 01 within the glass tubes 02, adjusting the insertion depth of the lens 01 into the glass tube 02, thereby controlling the length of the lens 01's tip extending from the front end of the glass tube 02. Preferably, the positioning surface 108 is made of silicone to prevent damage to the lens 01 due to impact caused by excessive movement of the assembly plate 101. After adjusting the length of the lens 01 extending from the front end of the glass tube 02, apply UV-curing adhesive through the gap between the lens 01 and the front end of the glass tube 02. After initial curing with ultraviolet light, transfer the glass tube 02 and lens 01 together to the later UV curing station for further UV curing to improve the connection strength.

[0026] Specifically, slide rails 200 are installed on both inner walls of the U-shaped base 100, and sliders 201 are installed on both sides of the positioning base plate 106 along its length 2, with the sliders 201 matching the slide rails 200. The arrangement of the slide rails 200 and sliders 201 improves the stability of the positioning base plate 106 during movement, ensuring high precision and consistent pushing distance for all lenses 01.

[0027] Specifically, positioning blocks 300 are provided on both sides of the outer surface of the assembly plate 101 along its length direction 2. The positioning blocks 300 can be used to position the double-sided adhesive 103 when it is replaced.

[0028] Specifically, a knob 400 is mounted on the outer surface of the rotating shaft 104, and a rubber sleeve is provided on the outer surface of the knob 400. The knob 400 facilitates the rotation of the rotating shaft 104, and the rubber sleeve increases the friction between the knob and the hand, reducing slippage and improving hand comfort.

[0029] Specifically, the U-shaped base 100, assembly plate 101, and positioning base plate 106 are all symmetrical structures. This symmetrical structure allows assembly operations to be performed on both the top and bottom surfaces of the fixture. Therefore, in actual operation, when the viscosity of the double-sided adhesive 103 decreases, the fixture can be flipped using a rotating mechanism (not shown in the figure), rotating the double-sided adhesive 103 located at the bottom to the top, thus allowing assembly operations to continue uninterrupted and improving assembly efficiency. Workers only need to replace both double-sided adhesives 103 periodically, reducing the frequency of replacement.

[0030] Specifically, both ends of the mounting plate 101 along the length direction 2 are connected to the U-shaped seat 100 by bolts. The bolt connection method facilitates replacement when the mounting plate 101 is damaged or when different specifications of collimator lenses 01 are assembled.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
