Description

Technical Field

[0001] This utility model relates to the field of coaxial light source technology, specifically to a coaxial refractive light source mechanism for a polarization-maintaining fiber fusion splicer. Background Technology

[0002] In the field of machine vision technology, coaxial light sources provide more uniform illumination than traditional light sources while avoiding glare from objects, thus improving the accuracy and reproducibility of machine vision. A patent with authorization announcement number CN216351696U, entitled "A Coaxial Light Source," includes a beam-splitting film. A lamp source and a reflective wall for light extinction are respectively located on both sides of the beam-splitting film. The reflective wall includes a substrate with multiple conical grooves and / or multiple conical protrusions. The bottom surface of the conical grooves faces the lamp source, and the bottom surface of the conical protrusions faces away from the lamp source. The surfaces of the conical grooves and protrusions are all blackened. With this coaxial light source, incident stray light can be reflected from the surfaces of the conical grooves or protrusions. Because the reflective surface is conical, light extinction can be achieved through more than two reflections, thus solving the problem of strong reflected light in existing technologies. However, in actual use, both the lamp source and the beam-splitting film are fixed in a mounting frame, making it inconvenient to remove, clean, or replace them. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a coaxial refractive light source mechanism for a polarization-maintaining fiber fusion splicer.

[0004] The technical solution adopted by this utility model to solve its technical problem is a coaxial refractive light source mechanism for a polarization-maintaining fiber optic fusion splicer, including a housing and a plug. The housing has through slots on both sides. Inside the housing are a beam-splitting lens, a diffuser lens, a pressure frame, a PCB board, and a heat-conducting mechanism. The diffuser lens is located between the beam-splitting lens and the pressure frame. The heat-conducting mechanism is located on the side of the PCB board away from the pressure frame. Rubber frames are fixed to both sides of the pressure frame. Multiple LED beads are fixed to the side of the PCB board away from the heat-conducting mechanism. The housing contains two... The first sliding groove is adapted to the beam splitter lens, and the outer shell has two second sliding grooves adapted to the diffuser lens. A notch is provided on one side of the outer shell, and a baffle is provided in the notch. Two locking blocks are integrally formed on the baffle. Two protrusions are integrally formed on the outer wall of the outer shell. The side walls of the two locking blocks are provided with locking grooves adapted to the protrusions. There are two insertion rods. The bottom ends of the two protrusions and locking blocks are provided with slots adapted to the ends of the insertion rods. The two locking blocks are provided with through grooves for the top ends of the insertion rods to pass through. Springs are sleeved on the two insertion rods, and pressure blocks are fixed to the top ends of the two insertion rods.

[0005] By adopting the above technical solution, pressing the two pressure blocks causes the two insertion rods to move downwards, and the ends of the two insertion rods disengage from the slots at the bottom of the two protrusions. Moving the baffle away from the outer casing allows the baffle to be removed. Pulling out the beam splitter and diffuser lens allows the beam splitter and diffuser lens to be removed from the outer casing for cleaning or replacement. After removing the diffuser lens, the pressure frame is removed from the outer casing, and then the PCB board is removed for maintenance or replacement.

[0006] Specifically, the heat-conducting mechanism includes thermally conductive silicone and a heat-conducting plate. The thermally conductive silicone is located between the PCB board and the heat-conducting plate. Multiple support plates are integrally formed on the side of the heat-conducting plate away from the thermally conductive silicone. All of the multiple support plates penetrate the outer shell and extend to the outside of the outer shell.

[0007] By adopting the above technical solution, the arrangement of thermally conductive silicone, thermally conductive plate and support plate facilitates the dissipation of heat from inside the shell.

[0008] Specifically, a handle is fixed to one side of the baffle.

[0009] By adopting the above technical solution, the handle makes it convenient to pick up and put down the baffle.

[0010] Specifically, the tops of both pressure blocks are integrally formed with multiple anti-slip protrusions.

[0011] By adopting the above technical solution, the anti-slip protrusions facilitate pressing the block.

[0012] Specifically, both sides of the outer shell are integrally formed with mounting plates, and both mounting plates are provided with multiple mounting holes.

[0013] By adopting the above technical solution, the mounting plate and mounting holes are designed to facilitate fixing the outer casing in a suitable position using bolts.

[0014] The beneficial effects of this utility model are:

[0015] (1) The coaxial refractive light source mechanism for polarization-maintaining fiber fusion splicer described in this utility model presses two pressure blocks, which drive two insertion rods to move down. The ends of the two insertion rods dislodge from the slots at the bottom of the two protrusions. The baffle can be removed by moving the baffle away from the outer shell. The beam splitter and diffuser can be removed from the outer shell for cleaning or replacement by pulling out the beam splitter and diffuser. After the diffuser is removed, the pressure frame is removed from the outer shell. Then the PCB board can be removed for maintenance or replacement.

[0016] (2) The coaxial refractive light source mechanism for polarization-maintaining fiber fusion splicer described in this utility model, with its thermally conductive silicone, thermally conductive plate and support plate, facilitates the heat dissipation from the inside of the shell.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To facilitate the disassembly, maintenance, or replacement of the beam-splitting lens 2, the diffuser lens 9, and the PCB board 11, as one embodiment of this utility model, such as... Figures 1 to 4 As shown, the coaxial refractive light source mechanism for a polarization-maintaining fiber optic fusion splicer of this utility model includes a housing 1 and a plug 7. The housing 1 has through slots on both sides. Inside the housing 1 are a beam-splitting lens 2, a diffuser lens 9, a pressure frame 10, a PCB board 11, and a heat-conducting mechanism 13. The diffuser lens 9 is located between the beam-splitting lens 2 and the pressure frame 10. The heat-conducting mechanism 13 is located on the side of the PCB board 11 away from the pressure frame 10. Rubber frames 15 are fixed to both sides of the pressure frame 10 with adhesive. Multiple LED beads 14 are fixed to the side of the PCB board 11 away from the heat-conducting mechanism 13. The housing 1 contains two... The outer casing 1 has a first sliding groove adapted to the beam splitter lens 2, and two second sliding grooves adapted to the diffuser lens 9. A notch is provided on one side of the outer casing 1, and a baffle 5 is provided in the notch. Two locking blocks 4 are integrally formed on the baffle 5. Two protrusions 3 are integrally formed on the outer wall of the outer casing 1. The side walls of the two locking blocks 4 are provided with locking grooves adapted to the protrusions 3. There are two insertion rods 7. The bottom ends of the two protrusions 3 and the locking blocks 4 are provided with slots adapted to the ends of the insertion rods 7. The two locking blocks 4 are provided with through grooves for the top ends of the insertion rods 7 to pass through. Springs 70 are fitted on the two insertion rods 7. Pressure blocks 71 are welded and fixed to the top ends of the two insertion rods 7.

[0025] When in use, press the two pressure blocks 71, which will cause the two insertion rods 7 to move down. The ends of the two insertion rods 7 will disengage from the slots at the bottom of the two protrusions 3. Move the baffle 5 away from the outer casing 1 to remove the baffle 5. At this time, the baffle 5 will no longer block the beam splitter lens 2 and the diffuser lens 9. Pull the beam splitter lens 2 and the diffuser lens 9 by hand to remove them from the outer casing 1 for cleaning or replacement. After removing the diffuser lens 9, remove the pressure frame 10 from the outer casing 1. Then remove the PCB board 11 for maintenance or replacement.

[0026] For ease of heat dissipation, for example, such as Figure 2 As shown, the heat conduction mechanism 13 includes thermally conductive silicone 12 and a heat conduction plate 16. The thermally conductive silicone 12 is located between the PCB board 11 and the heat conduction plate 16. Multiple support plates 17 are integrally formed on the side of the heat conduction plate 16 away from the thermally conductive silicone 12. The multiple support plates 17 all penetrate the outer shell 1 and extend to the outside of the outer shell 1.

[0027] To facilitate the removal and placement of the baffle 5, for example, such as Figure 1 As shown, a handle 6 is fixed to one side of the baffle 5 by adhesive.

[0028] To facilitate pressing the pressure block 71, for example, as follows: Figure 3 As shown, the tops of both pressure blocks 71 are integrally formed with multiple anti-slip protrusions 72.

[0029] For ease of installation of housing 1, for example, such as Figure 1 As shown, both sides of the outer shell 1 are integrally formed with mounting plates 8, and both mounting plates 8 are provided with multiple mounting holes.

[0030] Since the beam splitter 2, diffuser 9, PCB board 11 and LED beads 14 are all existing technologies, the specific principles will not be elaborated here. The setting of thermal conductive silicone 12, thermal conductive plate 16 and support plate 17 is conducive to the heat dissipation inside the outer shell 1. In specific implementation, heat dissipation holes or heat dissipation grooves can also be opened on the outer shell 1.

[0031] Press down on the two pressure blocks 71, and the two pressure blocks 71 will move the two insertion rods 7 down. The ends of the two insertion rods 7 will disengage from the slots at the bottom of the two protrusions 3. Move the baffle 5 away from the outer casing 1 to remove the baffle 5. At this time, the baffle 5 will no longer block the beam splitter lens 2 and the diffuser lens 9. Pull the beam splitter lens 2 and the diffuser lens 9 by hand to remove them from the outer casing 1 for cleaning or replacement. After removing the diffuser lens 9, remove the pressure frame 10 from the outer casing 1. Then remove the PCB board 11 to remove it for maintenance or replacement.

[0032] During installation, the PCB board 11 is placed inside the housing 1, the pressure frame 10 is placed on the side of the PCB board 11 away from the heat conduction mechanism 13, the diffuse lens 9 is placed in the second slide groove, and then the beam splitter 2 is placed in the first slide groove. The two pressure blocks 71 are pressed, the baffle 5 is placed in the notch on one side of the housing 1, the two pressure blocks 71 are released, the two springs 70 push the two pressure blocks 71 to move upward, and the ends of the two insert rods 7 are inserted into the slots at the bottom of the two protrusions 3, which can prevent the baffle 5 from shifting. The baffle 5 blocks the beam splitter 2 and the diffuse lens 9.
