Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector processing technology, and in particular to an integrated grinding structure for the end face of an MPO high-density fiber optic connector. Background Technology

[0002] MPO fiber optic connectors are high-density, multi-fiber connectors that provide a scalable and flexible solution for high-speed data transmission. Multi-fiber push-in (MPO) connectors are fiber optic connectors designed to accommodate multiple fibers in a single physical connector interface. They employ high-density packaging to reduce space requirements and increase port density.

[0003] MPO fiber optic connectors are often produced by injection molding, which involves injecting molten plastic into a mold cavity under high pressure using an injection molding machine. After cooling and solidification, the molded product is obtained. However, the edges of the injection-molded MPO fiber optic connector shell often produce scrap material. Therefore, processing equipment is needed to remove and grind the excess scrap material.

[0004] However, current processing equipment typically involves cutting the fiber optic connector on a cutting device before placing it in a grinding device for grinding, which increases the production steps of MPO fiber optic connectors and affects production efficiency. Therefore, an integrated grinding structure for the end face of MPO high-density fiber optic connectors is proposed to solve the above problems. Utility Model Content

[0030] like Figure 1-3 As shown, the present invention proposes an integrated grinding structure for the end face of an MPO high-density fiber optic connector, including a housing 1, a support frame 2 fixedly connected to the upper end of the housing 1, and a support member 3 for processing MPO fiber optic connectors provided on the support frame 2.

[0031] The housing 1 is equipped with a machining part 5 for cutting and polishing MPO fiber optic connectors;

[0032] The box 1 is equipped with a collection component 4 for collecting grinding and cutting waste.

[0033] In this invention, the MPO fiber optic connector that is fixedly supported can be slidably and rotated and adjusted by the support member 3 on the support frame 2, so that the workpiece 5 can be cut and ground.

[0034] In an optional embodiment, the support member 3 includes two sliding blocks 31 slidably connected to the support frame 2. An adjusting screw 32 with one end penetrating the front sliding block 31 is installed on the front side of the support frame 2. A guide rod 33 with one end penetrating the rear sliding block 31 is installed on the rear side of the support frame 2. A rotating block 39 is rotatably connected to the upper end of the front sliding block 31. A fixing screw 34 penetrating the rotating block 39 is threadedly connected to the middle of the rotating block 39. A sleeve rod 35 is threadedly connected to one end of the fixing screw 34 penetrating the rotating block 39. A vertical rod 37 is rotatably connected to the front side of the rear sliding block 31. A plurality of placement blocks 314 are fixedly connected to one end of the vertical rod 37 near the sleeve rod 35. A plurality of abutments 36 are fixedly connected to one end of the sleeve rod 35 near the vertical rod 37. A limiting rod 310 with one end penetrating the rotating block 39 is fixedly connected to one end of the sleeve rod 35 near the rotating block 39.

[0035] A telescopic rod 38 is installed between the vertical rod 37 and the sleeve rod 35, and a limiting element for limiting the rotation block 39 is provided on the front sliding block 31.

[0036] In this embodiment, since the rotating block 39 can rotate and adjust on the front sliding block 31 and is limited by the limiting member, after the rotating fixing screw 34 drives the abutment block 36 and the placement block 314 to clamp and fix the MPO fiber optic connector, the processing part 5 can be lowered to cut off the MPO fiber optic connector. After the MPO fiber optic connector is rotated and flipped, it can be ground by the processing part 5 that is lowered again to improve processing efficiency.

[0037] It should be noted that the telescopic rod 38 is U-shaped and consists of a sleeve and a sliding rod. The sleeve is fixedly connected to the sleeve rod 35, and the sliding rod is slidably connected inside the sleeve. The end of the sliding rod located outside the sleeve is fixedly connected to the vertical rod 37, so that the telescopic rod 38 is used to connect the sleeve rod 35 and the vertical rod 37 without affecting the telescopic adjustment of the sleeve rod 35.

[0038] The support frame 2 is rectangular, and rectangular grooves for sliding blocks 31 are provided on both the front and rear sides of the support frame 2. The sliding blocks 31 are convex in shape, and the guide rod 33 is fixedly connected in the rear rectangular groove, so that the two sliding blocks 31 slide symmetrically on the support frame 2.

[0039] In addition, the inner circumferential wall of the sleeve 35 is provided with an internal thread, and the internal thread is adapted to the thread on the outside of the fixing screw 34, so that the rotating adjusting screw 32 can adjust the sleeve 35 to move back and forth along the direction parallel to the horizontal plane, so as to drive the front abutment 36 to adjust towards or away from the placement block 314.

[0040] Secondly, the adjusting screw 32 is rotatably connected in the front rectangular groove, and the lower end of the front sliding block 31 is provided with a threaded hole, which is adapted to the thread on the outside of the adjusting screw 32, so that the rotating adjusting screw 32 can drive the front sliding block 31 to move laterally along the horizontal plane for adjustment.

[0041] Then, the placement block 314 is U-shaped, and a set of rubber blocks are fixedly connected to the inner side of each placement block 314. The rubber blocks are triangular, and the abutment block 36 is U-shaped. Several placement blocks 314 and abutment blocks 36 are fixedly connected from bottom to top, so that the placement blocks 314 and abutment blocks 36 can support and fix several MPO fiber optic connectors at each time, so that the processing surface or processing end of the MPO fiber optic connector faces the processing part 5. The rubber block located in the placement block 314 can fit tightly with the end of the MPO fiber optic connector to improve the clamping stability.

[0042] In an optional embodiment, the limiting member includes a mounting block 311 fixedly connected to the upper end of the front sliding block 31, and a pull rod 313 extending into the interior of the rotating block 39 is slidably connected to the mounting block 311. A spring 312 is installed between the upper end of the pull rod 313 and the mounting block 311.

[0043] In this embodiment, the pull rod 313 extending into the rotating block 39 can support and limit the rotating block 39. Conversely, by pulling the pull rod 313 to separate it from the rotating block 39, the rotating block 39 can be rotated on the front sliding block 31.

[0044] It should be noted that four limiting grooves are provided on the outer surface of the rotating block 39 away from the sleeve rod 35, and the four limiting grooves are distributed in a cross shape. The specifications of the limiting grooves are adapted to the specifications of the lower end of the pull rod 313. Since the pull rod 313 extending into the limiting groove can support and limit the rotating block 39, the pull rod 313 extending into different positions can support and limit the rotating block 39 after it has rotated 90 degrees.

[0045] In an optional embodiment, the upper end of the housing 1 is provided with an opening, and the collection component 4 includes a collection box 42 that is slidably connected to the opening of the housing 1 and located below the support frame 2. A filter screen 43 is installed on the inner bottom wall of the collection box 42, and a fan 41 is installed on the inner bottom wall of the housing 1.

[0046] In this embodiment, the waste material removed can be collected by the collection box 42 located at the opening of the box 1. In conjunction with the air pumping process of the fan 41, the dust generated during the cutting and grinding process of the MPO fiber optic connector can be adsorbed and then filtered by the filter screen 43 on the collection box 42, thereby facilitating the collection of waste material by the operator and reducing pollution to the surrounding environment.

[0047] It should be noted that the inner bottom wall of the housing 1 is connected to a rectangular horizontal plate located below the collection box 42. The collection box 42 is supported by the rectangular horizontal plate. The air inlet of the fan 41 is connected to the rectangular horizontal plate through conventional pipe fittings, so that the fan 41 can pump the air in the collection box 42 during the air pumping process, thereby adsorbing the dust in the MPO fiber optic connector during the processing.

[0048] The back of the housing 1 has an exhaust vent for air discharge.

[0049] In an optional embodiment, the processing component 5 includes a mounting bracket 51 fixedly connected to the back of the housing 1. A cylinder 52 is mounted on the upper end of the mounting bracket 51, and the output end of the cylinder 52 passes through the mounting bracket 51. A mounting plate 53 is fixedly connected to the output end of the cylinder 52. A dual-axis motor 54 is mounted below the mounting plate 53. A cutting blade 55 is mounted on one output shaft of the dual-axis motor 54, and a grinding disc 56 is mounted on the other output shaft of the dual-axis motor 54.

[0050] In this embodiment, the activated cylinder 52 can drive the mounting plate 53 to rise and fall vertically, while the activated dual-axis motor 54 can drive the cutting blade 55 and the grinding disc 56 to rotate, respectively cutting and grinding the MPO fiber optic connector.

[0051] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0052] The working principle in the above embodiments is as follows:

[0053] When the two sliding blocks 31 are located on one side below the dual-axis motor 54, the MPO fiber optic connector to be processed and of appropriate quantity can be placed between the abutment block 36 and the placement block 314. Then, by rotating the fixing screw 34 and adjusting the moving sleeve 35 towards the side of the rear sliding block 31, the abutment block 36 can be moved closer to the rear placement block 314 to clamp and fix the MPO fiber optic connector, so that the processing surface or processing end of the MPO fiber optic connector faces the cutting blade 55.

[0054] After the MPO fiber optic connector is fixed, the adjusting screw 32 can be rotated to drive the front sliding block 31 to adjust laterally on the support frame 2. Then, with the sleeve rod 35, telescopic rod 38 and vertical rod 37, the rear sliding block 31 can be moved and adjusted together. After the fixed MPO fiber optic connector to be cut is moved to below the cutting blade 55, the cylinder 52 can be activated to lower the mounting plate 53, so that the cutting blade 55 driven by the dual-axis motor 54 can cut off the waste material on the side or end of the MPO fiber optic connector to be cut.

[0055] After the cut-off portion of the MPO fiber optic connector is removed, the adjusting screw 32 can be rotated to move the sliding block 31 toward one side of the polishing disc 56, driving the removed MPO fiber optic connector to the underside of the polishing disc 56. Then, after pulling the lever 313 to separate it from the rotating block 39, the rotating block 39 can be rotated by the fixing screw 34 to rotate the cut-off portion of the MPO fiber optic connector 180 degrees. After the resetting lever 313 supports the rotating block 39 again, the cut-off portion of the MPO fiber optic connector can be rotated to the underside of the polishing disc 56. Then, the polishing disc 56 driven by the dual-axis motor 54 is lowered by the cylinder 52. Finally, the adjusting screw 32 is rotated in the opposite direction to drive the fixed cut-off portion of the MPO fiber optic connector to fit against the polishing disc 56 for polishing.

[0056] During the cutting and polishing process, rotating the rotating block 39 by ninety degrees can adjust one side or one end of the MPO fiber optic connector to face the cutting blade 55 and the polishing disc 56, which facilitates processing different sides or both ends of the MPO fiber optic connector. During the processing, the side or one end of the MPO fiber optic connector facing the telescopic rod 38 can be positioned inside the telescopic rod 38 as it descends.

[0057] Waste material removed during the cutting process can fall into the collection box 42 for collection, while the fan 41 activated during the grinding process can draw air to draw and adsorb the dust generated during grinding into the collection box 42, where it is blocked and filtered by the filter screen 43.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
