Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber array waveguide processing, in particular to an optical fiber array waveguide glue dispensing and product collision prevention fixture. Background Art

[0002] Fiber optic arrays are primarily used for image transmission. They consist of numerous optical fibers arranged in a specific sequence with their end faces arranged into the desired geometric shape. The fibers at both ends of the array correspond to each other, and each fiber in the array is equivalent to a pixel. The optical image at one end of the array is reproduced at the other end. Applications include planar waveguides, arrayed waveguide gratings, active / passive fiber optic array devices, micro-electromechanical systems (MEMS), and multi-channel optical modules. Fiber optic arrays utilize V-grooves to mount a single fiber, a bundle of fibers, or a fiber ribbon onto an array substrate and adhere them with glue. At the front end, the fibers are precisely positioned for connection to a PLC.

[0003] However, during the dispensing process, the optical fiber array is usually fixed using the optical fiber portion of an optical fiber array waveguide dispensing fixture. For example, patent publication number CN215313553U discloses an optical fiber array dispensing fixture, which includes a clamp, and the clamp includes two clamping arms. Both clamping arms include a handle and a chuck disposed at one end of the handle. The two handles are hinged, and the two chucks are closed to form a mounting hole. The mounting hole is opened along the height direction of the chuck and matches the optical fiber array. When the above-mentioned dispensing fixture is used, the optical fiber array is set in the mounting hole, and then adhesive is injected into the glue tank. The adhesive flows from the glue tank into the mounting hole, and the optical fiber array can be dispensed at one time, thereby speeding up the dispensing rate.

[0004] In the actual dispensing process, the above dispensing fixture can only dispense glue to a single optical fiber array waveguide, cannot dispense glue quickly, and has low dispensing efficiency. Utility Model Content

[0005] The utility model provides an optical fiber array waveguide glue dispensing anti-product collision fixture, which solves the problem of low glue dispensing efficiency in the prior art.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A fiber optic array waveguide dispensing and product collision prevention fixture includes a base, a head positioning assembly, and a tail pressing assembly. The head positioning assembly is provided with multiple positioning grooves arranged side by side on one side near the tail pressing assembly. The optical fiber heads of the fiber optic array waveguides cooperate with the positioning grooves, which can position the multiple optical fiber heads, allowing the multiple fiber optic array waveguides to be arranged side by side, and the dispensing positions of each fiber optic array waveguide to be arranged side by side. The tail pressing assembly presses the optical fiber tails of the fiber optic array waveguides, fixing the multiple fiber optic array waveguides, achieving positioning and clamping of the multiple fiber optic array waveguides on the fixture. In the subsequent dispensing process, multiple fiber optic array waveguides can be dispensed simultaneously, improving dispensing efficiency.

[0008] The head positioning assembly includes a horizontally arranged top positioning bar. Near the tail clamping assembly, a plurality of side positioning bars are arranged side by side. Two adjacent side positioning bars cooperate with the top positioning bar to form a positioning groove. The top and side positioning bars position the fiber head, ensuring accurate placement of the fiber array waveguide on the fixture and facilitating subsequent glue dispensing operations.

[0009] The length of the side positioning strip is less than the length of the optical fiber head. The side positioning strip does not contact the tail of the optical fiber, and thus does not contact the glue dispensing position of the optical fiber array waveguide, effectively preventing the side positioning strip from sticking to the optical fiber head during glue dispensing.

[0010] The distance between the two adjacent side positioning strips is equal to the width of the optical fiber head. The two side positioning strips cooperate to position the optical fiber head in the radial direction to prevent the optical fiber head from shaking left and right during glue dispensing.

[0011] The tail clamping assembly includes a pressure plate and a spring. The pressure plate is placed on the base, with one end of the spring flexibly connected to the base and the other end of the pressure plate tightly engaged with the pressure plate. After the optical fiber array waveguide is placed on the base, the pressure plate is placed on the base, with the bottom surface of the pressure plate contacting the tail of the optical fiber of the optical fiber array waveguide. The spring is then moved onto the pressure plate, applying a downward force to the tail of the optical fiber. The pressure plate and the base cooperate to clamp the tail of the optical fiber, thereby securing the optical fiber array waveguide on the base.

[0012] The bottom of the pressing plate is provided with an elastic buffer layer. The elastic buffer layer is a rubber layer. When the pressing plate presses the tail of the optical fiber, the elastic buffer layer contacts the tail of the optical fiber, and the elastic buffer layer protects the optical fiber array waveguide, preventing the pressing plate from damaging the optical fiber.

[0013] The base is provided with L-shaped pressure plate positioning ribs that mate with the corners of the pressure plate. These ribs position the pressure plate on the base, ensuring that it is accurately positioned on the base and that it can compress the optical fiber array waveguide.

[0014] The base is provided with a connecting post, one end of the spring piece is rotatably connected to the connecting post. The spring piece rotates on the connecting post to apply or remove downward pressure on the pressure plate, facilitating the removal and installation of the pressure plate and further facilitating the installation of the optical fiber array waveguide on the base.

[0015] There is at least one connecting post, which corresponds to the position of the side positioning strip. When the fiber array waveguide is placed on the base, the connecting post does not interfere with the fiber tail, ensuring the normal use of the clamp. At the same time, each connecting post is equipped with a spring clip, which together presses the pressure plate to improve the clamping stability of the pressure plate on the fiber tail.

[0016] The base is provided with a strip groove, which corresponds to the glue dispensing position of the optical fiber array waveguide. During glue dispensing, the glue adheres to the glue dispensing position of the optical fiber array waveguide, and due to the provision of the strip groove, the glue does not contact the base, thereby preventing the optical fiber array waveguide from adhering to the base.

[0017] The beneficial effects of the present invention are as follows: the positioning grooves on the head positioning assembly can simultaneously position multiple optical fiber heads, so that multiple optical fiber array waveguides are arranged side by side, and the glue dispensing positions of each optical fiber array waveguide are arranged side by side, which is convenient for glue dispensing; the tail pressing assembly presses and fixes each optical fiber tail, realizes the positioning and clamping of multiple optical fiber array waveguides on the fixture, and can dispense glue on multiple optical fiber array waveguides at the same time in the subsequent glue dispensing process, thereby improving the glue dispensing efficiency; the optical fiber tail is pressed by the combination of the pressure plate and the spring piece, which is convenient for the installation or removal of the pressure plate on the base, and further facilitates the rapid installation and clamping of the optical fiber array waveguide on the fixture.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1, as Figure 1 、 Figure 2 、 Figure 3 As shown, a fiber array waveguide dispensing and product collision prevention fixture includes a base 1, which is provided with a head positioning component 5 and a tail pressing component. The head positioning component 5 has a plurality of positioning grooves arranged side by side on the side near the tail pressing component. The positioning grooves on the head positioning component 5 position the optical fiber head 6 to ensure that the optical fiber array waveguide is accurately placed on the base 1. The tail pressing component presses the optical fiber tail 61 to achieve the fixation of the optical fiber array waveguide on the base 1. During the dispensing process, the optical fiber array waveguide is fixed to the base 1. At the same time, the fixture can clamp and position multiple optical fiber array waveguides simultaneously, improving the dispensing efficiency.

[0025] Furthermore, the head positioning assembly 5 includes a transversely arranged top positioning bar 52. A plurality of side positioning bars 51 are arranged side by side on one side of the top positioning bar 52, near the tail clamping assembly. Two adjacent side positioning bars 51 cooperate with the top positioning bar 52 to form a positioning groove. The top positioning bar 52 and the side positioning bars 51 position the optical fiber head 6, ensuring accurate placement of the optical fiber array waveguide on the fixture and facilitating subsequent glue dispensing operations.

[0026] Furthermore, the length of the side positioning strip 51 is less than the length of the optical fiber head 6. The side positioning strip 51 has no contact with the optical fiber tail 61, thereby making the side positioning strip 51 have no contact with the glue dispensing position of the optical fiber array waveguide, effectively avoiding the side positioning strip 51 and the optical fiber head 6 from adhering during glue dispensing. The spacing between the two adjacent side positioning strips 51 is equal to the width of the optical fiber head 6. The two side positioning strips 51 cooperate to position the optical fiber head 6 radially to avoid the optical fiber head 6 shaking left and right during glue dispensing. In addition, the side positioning strip 51 separates the two adjacent optical fiber array waveguides to prevent the optical fiber heads 6 from colliding with each other, thereby avoiding damage and scrapping of the optical fiber array waveguide.

[0027] Example 2, based on Example 1, is a fixture for dispensing and preventing product collisions for optical fiber array waveguides. The tail clamping assembly includes a pressure plate 3 and a spring plate 4. The pressure plate 3 is placed on the base 1. One end of the spring plate 4 is movably connected to the base 1, and the other end of the pressure plate 4 is pressed and fitted with the pressure plate 3. After the optical fiber array waveguide is placed on the base 1, the pressure plate 3 is placed on the base 1. The bottom surface of the pressure plate 3 contacts the optical fiber tail 61 of the optical fiber array waveguide. The spring plate 4 is then moved onto the pressure plate 3, so that the pressure plate 3 exerts a downward force on the optical fiber tail 61. The pressure plate 3 cooperates with the base 1 to clamp the optical fiber tail 61, thereby fixing the optical fiber array waveguide on the base 1.

[0028] Furthermore, an elastic buffer layer is provided at the bottom of the pressing plate 3. The elastic buffer layer is a rubber layer. When the pressing plate 3 presses the optical fiber tail 61, the elastic buffer layer contacts the optical fiber tail 61. The elastic buffer layer protects the optical fiber array waveguide and prevents the pressing plate 3 from damaging the optical fiber.

[0029] Furthermore, the base 1 is provided with a pressure plate positioning rib 2. The pressure plate positioning rib 2 is an L-shaped structure and cooperates with the corners of the pressure plate 3. The pressure plate positioning rib 2 positions the pressure plate 3 on the base 1, ensuring that the pressure plate 3 is accurately placed on the base 1, thereby ensuring that the pressure plate 3 can press the optical fiber array waveguide tightly.

[0030] Furthermore, the base 1 is provided with a connecting post 11, to which one end of the spring 4 is rotatably connected. The spring 4 rotates on the connecting post 11 to apply or remove downward pressure on the pressure plate 3, facilitating the removal and installation of the pressure plate 3 and, in turn, the installation of the optical fiber array waveguide on the base 1.

[0031] Furthermore, there is at least one connecting post 11, and the position of the connecting post 11 corresponds to the position of the side positioning strip 51. In this embodiment, there are two connecting posts 11, and the spring clip 4 is rotatably connected to the connecting posts 11. When the optical fiber array waveguide is placed on the base 1, the connecting posts 11 will not interfere with the optical fiber tail 61, ensuring the normal use of the clamp. At the same time, each connecting post 11 is equipped with a spring clip 4, and multiple spring clips 4 work together to press the pressure plate 3, improving the clamping stability of the pressure plate 3 on the optical fiber tail 61.

[0032] Furthermore, the base 1 is provided with a strip groove 12, which corresponds to the glue dispensing position of the optical fiber array waveguide. During glue dispensing, the glue adheres to the glue dispensing position of the optical fiber array waveguide, and due to the provision of the strip groove 12, the glue does not come into contact with the base 1, thus preventing the optical fiber array waveguide from adhering to the base 1.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
