[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0044] Please refer to Figures 1-4. The present invention provides the following technical solution: a fiber optic connector curing device, including a workbench 1 and a UVLED light source 3 disposed above the workbench 1, further including: a clamping mechanism 5 and a translational force component 6, wherein the clamping mechanism 5 includes: a movable seat 51, a fixed upright plate 52, a plurality of pneumatic grippers 53 and a rotational power component 54, and the translational force component 6 is used to drive the clamping mechanism 5 to move horizontally.

[0045] Further, as shown in Figures 1 and 2, in this embodiment, the movable seat 51 is movably connected to the workbench 1, the fixed plate 52 is fixed to the top surface of the movable seat 51, and multiple pneumatic grippers 53 are evenly distributed along the horizontal direction and rotatably connected to the fixed plate 52. The rotation power assembly 54 is used to drive the pneumatic grippers 53 to rotate. With the above scheme, when using it, the fiber optic connector to be cured is first placed in the clamping area of ​​the pneumatic gripper 53. The pneumatic gripper 53 is powered by the pneumatic system to clamp and fix the fiber optic connector.

[0046] When the translational motion component 6 is activated, it drives the movable seat 51 to move horizontally on the worktable 1, thereby moving the fixed upright plate 52, the pneumatic gripper 53 and the fiber optic connector mounted on it together.

[0047] When the clamping mechanism 5 moves to a suitable position below the UVLED light source 3, the translational force component 6 stops moving. At this time, the rotational power component 54 starts working, driving the pneumatic gripper 53 to rotate around its own rotation axis. Since the fiber optic connector is clamped by the pneumatic gripper 53, it will rotate together with the pneumatic gripper 53.

[0048] The UVLED light source 3 emits ultraviolet light to irradiate the curing material on the surface of the fiber optic connector. Under the action of the rotating power component 54, the fiber optic connector can receive ultraviolet irradiation from 360 degrees, ensuring that the curing material can be uniformly cured from all angles, thereby improving the curing quality and effect.

[0049] After curing is complete, the rotary power component 54 stops driving, the translational power component 6 starts again, and drives the clamping mechanism 5 to return to the initial position along the original path. Then, the pneumatic gripper 53 releases and removes the cured optical fiber connector, completing one curing operation.

[0050] Throughout the process, the translational motion component 6 and the rotational motion component 54 work together to achieve precise movement and rotation of the fiber optic connector during the curing process, enabling the UVLED light source 3 to provide comprehensive and uniform irradiation to the fiber optic connector, thus ensuring the efficient and stable operation of the curing equipment.

[0051] Optionally, as shown in Figures 1 and 2, in this embodiment, the rotary power assembly 54 includes: a rotating rod 541, a driven gear 542, a driving gear 543, and a first drive motor 544. One end of the rotating rod 541 is fixedly connected to the pneumatic gripper 53, and the other end is rotatably connected to the fixed plate 52 via a bearing. The driven gear 542 is fixed on the rotating rod 541, and the driven gears 542 on multiple rotating rods 541 mesh sequentially. The driving gear 543 is rotatably connected to the fixed plate 52 and meshes with the rotating rod 541. The first drive motor 544 is fixed to the outer wall of the fixed plate 52 and is used to drive the driving gear 543 to rotate. With the above scheme, when the clamping mechanism 5 moves to the curing station directly below the UVLED light source 3, the first drive motor 544 starts to work.

[0052] The output shaft of the No. 1 drive motor 544, which serves as the power source, is fixedly connected to the drive gear 543. When it rotates, it directly drives the drive gear 543 to rotate clockwise or counterclockwise on the bearing position on the fixed plate 52.

[0053] The driving gear 543 meshes with the driven gear 542 at the head end. Through the meshing of the gear teeth, the rotational power is transmitted to the first rotating rod 541, which drives the corresponding pneumatic gripper 53 to rotate synchronously.

[0054] Preferably, as shown in Figures 1 and 2, in this embodiment, the clamping mechanism 5 further includes a rubber block 55, which is fixed on the gripper of the pneumatic gripper 53. With the above solution, the high coefficient of friction of the rubber material can significantly improve the contact friction between the pneumatic gripper 53 and the surface of the optical fiber connector during use, and can effectively prevent the connector from circumferentially sliding or axially moving even under high-speed rotation conditions.

[0055] In addition, the elastic buffering effect of the rubber block 55 can eliminate the rigid stress concentration when the jaws are clamped. It can provide sufficient clamping force and absorb mechanical vibration through micro-deformation during the clamping process, preventing surface damage such as scratches and indentations caused by direct contact of the jaws, and ensuring that the optical performance of the connector is not affected.

[0056] Optionally, as shown in Figures 1 and 3, in this embodiment, the translational motion component 6 includes: two fixed plates 61, a threaded screw 62, and a second drive motor 63. The two fixed plates 61 are symmetrically fixed to the top surface of the workbench 1. The threaded screw 62 is rotatably installed between the two fixed plates 61 and is threadedly engaged with the movable seat 51. The second drive motor 63 is fixed to the outer wall of the fixed plate 61 and is used to drive the threaded screw 62 to rotate. With the above scheme, when in use, the second drive motor 63 starts, and its output shaft drives the threaded screw 62 to rotate through a coupling. Since the threaded screw 62 is rotatably installed between the two fixed plates 61 and is threadedly engaged with the movable seat 51, the rotation of the threaded screw 62 can be converted into linear movement of the movable seat 51, so that the clamping mechanism 5 can be transferred between different workstations.

[0057] Preferably, as shown in Figures 1 and 3, in this embodiment, the translational force component 6 further includes two guide rods 64, which are symmetrically fixed between two fixed plates 61 and pass through the movable seat 51. With the above solution, during use, the two guide rods 64 are used to support and guide the movable seat 51, which further improves the stability of the movable seat 51.

[0058] Preferably, as shown in Figures 1 and 4, in this embodiment, the UVLED light source 3 includes a plurality of UVLED lamp beads 31 arranged in a linear array. With the above scheme, when in use, the linear array layout makes the UVLED lamp beads 31 form a continuous surface illumination area, which can completely cover its curing area and avoid the problem of under-curing at both ends caused by distance attenuation in traditional single-point light sources.

[0059] Preferably, as shown in Figure 1, this embodiment further includes: a fixed frame 2 and a lifting mechanism 4. The fixed frame 2 includes two side plates 21 symmetrically fixed to the top surface of the workbench 1 and a top plate 22 fixed to the top of the side plates 21. The lifting mechanism 4 includes a lifting plate 41 located below the top plate 22 and an electric push rod 42 fixed to the top surface of the top plate 22. The UVLED light source 3 is fixed to the bottom surface of the lifting plate 41, and the piston rod of the electric push rod 42 passes through the top plate 22 and is fixedly connected to the lifting plate 41. With the above solution, when the equipment enters the curing preparation stage, according to the model of the fiber optic connector to be processed (such as FC type, LC type, etc.), the electric push rod 42 is activated, and the piston rod of the electric push rod 42 drives the lifting plate 41 to rise and fall, so that the UVLED light source 3 rises and falls, adjusting the initial height of the UVLED light source 3 to adapt to the light energy reception differences of different sized fiber optic connectors, ensuring that different specifications of fiber optic connectors obtain the best illumination distance and angle during the curing process.

[0060] Preferably, as shown in Figure 1, in this embodiment, the lifting mechanism 4 further includes two guide columns 43, which are symmetrically fixed to the top surface of the lifting plate 41 and penetrate the top plate 22. With the above solution, during use, the two guide columns 43 are used to guide the lifting plate 41, which further improves the stability of the lifting plate 41.

[0061] It should be noted that the UVLED light source 3, electric push rod 42, pneumatic gripper 53, drive motor 544 and drive motor 63 are all commercially available conventional equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0062] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0063] Components not described in detail in this article are existing technologies.

[0064] The working principle and usage process of this utility model: When using the curing device of this utility model, the optical fiber connector to be cured is first placed in the clamping area of ​​the pneumatic gripper 53. The pneumatic gripper 53 is powered by the pneumatic system to clamp and fix the optical fiber connector.

[0065] When the translational force component 6 is activated, it drives the movable seat 51 to move horizontally on the worktable 1, thereby moving the fixed upright plate 52, the pneumatic gripper 53 and the fiber optic connector mounted on it together.

[0066] When the clamping mechanism 5 moves to a suitable position below the UVLED light source 3, the translational force component 6 stops moving. At this time, the rotational power component 54 starts working, driving the pneumatic gripper 53 to rotate around its own rotation axis. Since the fiber optic connector is clamped by the pneumatic gripper 53, it will rotate together with the pneumatic gripper 53.

[0067] The UVLED light source 3 emits ultraviolet light to irradiate the curing material on the surface of the fiber optic connector. Under the action of the rotating power component 54, the fiber optic connector can receive ultraviolet irradiation 360 degrees, ensuring that the curing material can be uniformly cured from all angles, thereby improving the curing quality and effect.

[0068] After curing is complete, the rotary power component 54 stops driving, the translational power component 6 starts again, and drives the clamping mechanism 5 to return to the initial position along the original path. Then, the pneumatic gripper 53 releases and removes the cured optical fiber connector, completing one curing operation.

[0069] Throughout the process, the translational motion component 6 and the rotational motion component 54 work together to achieve precise movement and rotation of the fiber optic connector during the curing process, enabling the UVLED light source 3 to provide comprehensive and uniform irradiation to the fiber optic connector, thus ensuring the efficient and stable operation of the curing equipment.

[0070] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
