Description

Technical Field

[0001] This invention relates to the field of fiber optic patch cord connector crimping technology, specifically to a fiber optic patch cord connector crimping device. Background Technology

[0002] Fiber optic patch cords are used to connect devices to fiber optic cabling links. They have a thick protective layer and are typically used for connections between optical transceivers and terminal boxes, in applications such as fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks. Fiber optic patch cord fabrication generally involves fixing the fiber optic cable and connector to a crimping ring. The crimping ring is deformed by the upper and lower dies in a crimping device to secure the fiber optic cable and connector.

[0003] However, current crimping devices require users to hold the fiber optic cable and connector by hand and place the crimping ring on the lower mold of the crimping device. During the crimping process, the user must keep holding the fiber optic cable and connector. This operation method poses a safety hazard of pinching and injuring personnel and has low safety. Therefore, a new technical solution has been developed in actual production to solve the above technical problems. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a fiber optic patch cord connector crimping device that offers advantages such as safe operation and stable crimping quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a fiber optic patch cord connector crimping device, comprising an upper mold, a mold base, a circulation mechanism, multiple sets of templates, and a pressing mechanism;

[0007] The mold base is located directly below the upper mold, and the extrusion mechanism is used to push the upper mold to move vertically;

[0008] The circulating mechanism is used to drive multiple sets of templates to circulate between the template base and the upper template one by one. The pressure ring and the fiber optic connector are placed on the template, and each set of templates is provided with a clamping mechanism for holding the fiber optic cable.

[0009] When a set of templates is located directly above the mold base, the mold base and the templates form the lower mold. The extrusion mechanism pushes the upper mold down and deforms the pressure ring by cooperating with the lower mold. After the extrusion is completed, the snap-fit ​​mechanism pushes the optical fiber away from the snap-fit ​​mechanism, releases the clamping of the optical fiber, and pushes the pressure ring and optical fiber connector off the template.

[0010] By adopting the above technical solution, the crimping ring and fiber optic connector are placed on a template away from the upper mold, and the fiber optic cable is clamped by a clamping mechanism. Then, a circulating mechanism moves the template containing the crimping ring and fiber optic connector, and the clamping mechanism, to directly above the mold base. At this time, the template and the mold base below together form the lower mold for crimping. The pressing mechanism drives the upper mold to move downward and cooperate with the lower mold, working together to cause plastic deformation of the crimping ring, thereby completing the crimping and fixing of the fiber optic cable and fiber optic connector. After crimping, the clamping mechanism automatically pushes the crimped fiber optic cable away from the clamped state, releasing its constraint, and assists in pushing the crimped components (crimping ring and fiber optic connector) off the template so that the template can enter the next cycle. In the above process, the safety hazards caused by the operator having to hold the fiber optic cable under the crimping force in the traditional process are fundamentally avoided, significantly improving operational safety. At the same time, the cyclic use of the template ensures the consistency of crimping quality and the continuity of production, effectively solving the problems of poor safety and unstable quality in the existing technology.

[0011] Preferably, the circulation mechanism includes two side plates and a circulation chain drive mechanism disposed between the two side plates. The mold base is horizontally disposed between the two side plates via a support platform. Multiple sets of the mold plates are driven by the circulation chain drive mechanism to circulate between the mold base and the upper mold one by one.

[0012] Preferably, each set of templates includes several mounting plates arranged at intervals along the length of the mold base, and each mounting plate is provided with a concave mold and a pad. The concave mold is used to place the pressure ring, and the pad is used to place the fiber optic connector. When each mounting plate in a set of templates is located directly above the mold base, the mold base and the concave mold are vertically aligned, and the concave molds on each mounting plate are of different sizes.

[0013] The snap-fit ​​mechanism includes a vertical plate and a fixed plate respectively disposed on each mounting plate. The fixed plate is located below one side of the vertical plate, and the fixed plate and the vertical plate are arranged in an L-shape. Each fixed plate is provided with a pressing module, which is used to press the optical fiber against the vertical plate. After the pressing is completed, the pressing module pushes the optical fiber away from the vertical plate and pushes the pressure ring and optical fiber connector off the concave mold and the pad.

[0014] Preferably, the pressing module includes a rotating mechanism, a pressure roller, and a linear drive component. The linear drive component is used to drive the pressure roller to approach the upright plate and press the optical fiber line against one side of the upright plate. The optical fiber line is parallel to the axis of the pressure roller. When the pressing is completed and the template is circulated to the bottom of the mold base, the rotating mechanism drives the pressure roller to rotate, so that the pressure roller pushes the optical fiber line out from between the upright plate and the pressure roller.

[0015] Preferably, a right-angled triangular connecting plate is provided at the angle between the fixing plate and the upright plate, and the inclined surface of the connecting plate is an arc-shaped surface adapted to the pressure roller.

[0016] Preferably, the rotating mechanism includes a rotating shaft coaxially mounted on the pressure roller, and a gear is provided on the rotating shaft. A rack that meshes with the gear is mounted on one of the side plates via a mounting component. When the pressing is completed and the template circulates to the bottom of the mold base, the gear meshes with the rack. Then, as the template moves, the gear and the rack mesh, causing the gear to drive the pressure roller to rotate via the rotating shaft.

[0017] Preferably, the linear drive includes a tension spring, a slide block, and a connecting groove disposed at the top of the mounting plate. The slide block is horizontally slidably connected to the fixed plate, and the pressure roller is rotatably connected to the slide block. The bottom end of the slide block is provided with a vertical plate, and the bottom end of the vertical plate passes through the connecting groove and extends to the bottom of the mounting plate. The bottom end of the mounting plate is provided with a suspension plate, and the tension spring is disposed between the suspension plate and the vertical plate.

[0018] Preferably, when all the mounting plates in a set of templates are located directly above the mold base, the suspension plate, vertical plate and tension spring are all located on one side of the mold base.

[0019] Preferably, the upper mold is provided with a positioning mechanism. When all the mounting plates in a set of templates are located directly above the mold base and the upper mold is pressed down, the positioning mechanism is used to position the mounting plates on the mold base.

[0020] Preferably, the positioning mechanism includes a plurality of positioning rods and inserts on each mounting plate in each set of templates. When the upper mold is pressed down, the upper mold drives each of the positioning rods to move downward, so that the bottom end of each positioning rod is inserted into each insert, and the bottom end face of each positioning rod is a pointed tip.

[0021] The beneficial effects of this invention are as follows: The clamping ring and fiber optic connector are placed on a template away from the upper mold, and the fiber optic cable is clamped by a snap-fit ​​mechanism. Then, the template containing the clamping ring and fiber optic connector, and the fiber optic cable clamped by the snap-fit ​​mechanism, is moved to the top of the mold base by a circulation mechanism. At this time, the template and the mold base below together form the lower mold for crimping. At this time, the pressing mechanism drives the upper mold to move downward and cooperate with the lower mold, working together to cause the clamping ring to undergo plastic deformation, thereby completing the crimping and fixing of the fiber optic cable and fiber optic connector. After crimping, the snap-fit ​​mechanism automatically pushes the crimped fiber optic cable away from the clamped state, releasing its constraint, and assists in pushing the crimped components (clamping ring and fiber optic connector) off the template so that the template can enter the next cycle. In the above process, the safety hazards caused by the operator having to hold the fiber optic cable under the crimping force in the traditional process are fundamentally avoided, and the operational safety is significantly improved.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] A fiber optic patch cord connector crimping device, such as Figure 1 and Figure 2 It includes a base plate 1 and an upper mold 2, a mold base 3, a circulation mechanism, multiple sets of templates 4, and an extrusion mechanism, all mounted on the base plate 1. The extrusion mechanism includes a column 11 mounted on the top of the base plate 1, and a horizontal plate 111 is horizontally mounted on the top of the column 11. An electric cylinder 112 is mounted on the horizontal plate 111, and one end of the piston rod of the electric cylinder 112 passes through the horizontal plate 111 and is connected to the upper mold 2.

[0035] The die base 3 is located directly below the upper die 2, and the extrusion mechanism is used to push the upper die 2 to move vertically;

[0036] The circulation mechanism is used to drive multiple sets of templates 4 to circulate between the template base 3 and the upper template 2 one by one. The pressure ring 61 and the fiber optic connector 62 are placed on the template 4, and each set of templates 4 is provided with a clamping mechanism for holding the fiber optic cable 6.

[0037] When a set of templates 4 is located directly above the template 3, the template 4 and the template 3 form a lower mold. The pressing mechanism pushes the upper mold 2 down and deforms the pressing ring 61 by cooperating with the lower mold. After the pressing is completed, the clamping mechanism pushes the optical fiber 6 away from the clamping mechanism, releases the clamp on the optical fiber 6, and pushes the pressing ring 61 and the optical fiber connector 62 off the template 4.

[0038] like Figure 1 and Figure 2 The crimping ring 61 and the fiber optic connector 62 are placed on a template 4 away from the upper mold 2, and the fiber optic cable 6 is clamped by a snap-fit ​​mechanism. Then, the template 4, on which the crimping ring 61 and the fiber optic connector 62 are placed and the fiber optic cable 6 is clamped by the snap-fit ​​mechanism, is moved to the top of the mold base 3 by a circulation mechanism. At this time, the template 4 and the mold base 3 below together form the lower mold for crimping. At this time, the electric cylinder 112 is activated. The piston rod of the electric cylinder 112 drives the upper mold 2 to move downward and cooperate with the lower mold. Together they act on the crimping ring 61 to cause it to undergo plastic deformation, thereby completing the crimping and fixing of the fiber optic cable 6 and the fiber optic connector. After the crimping is completed, the snap-fit ​​mechanism automatically pushes the crimped fiber optic cable 6 away from the clamped state, releases its constraint, and assists in pushing the crimped components (crimping ring 61 and fiber optic connector) off the template 4 so that the template 4 can enter the next cycle. In the above process, the safety hazards caused by the operator having to hold the fiber optic cable 6 under the crimping force in the traditional process are fundamentally avoided, and the operational safety is significantly improved.

[0039] like Figure 1 and Figure 2 The circulation mechanism includes two side plates 51 and a circulation chain drive mechanism disposed between the two side plates 51. The two side plates 51 are mounted on the base plate 1 via a support frame 5. The mold base 3 is horizontally disposed between the two side plates 51 via a support platform 31. Multiple sets of mold plates 4 are driven by the circulation chain drive mechanism to circulate sequentially between the mold base 3 and the upper mold 2. The circulation chain drive mechanism includes two sprockets 511 rotatably connected to each side plate 51, and the two sprockets 511 are connected by a chain 5111. The sprockets 511 on the two side plates 51 correspond one-to-one and are connected by a drive shaft 5112. Multiple sets of templates 4 are arranged between two chains 5111 and are evenly distributed along the circumference of the chains 5111. One of the side plates 51 is equipped with a servo motor 512 for driving one of the sprockets 511 to rotate. Both side plates 51 are equipped with baffles 514, and the baffles 514 are in contact with the inner top of the chains 5111. The opposite sides of the mold base 3 are provided with inclined surfaces for the templates 4 to slide horizontally into the mold base 3. Through the inclined surfaces on the templates 4 and the baffles 514, the chains 5111 can easily transport the templates 4 to the mold base 3, reducing the possibility of the templates 4 getting stuck on the mold base 3.

[0040] The working process of the circulation mechanism is as follows:

[0041] like Figure 1 and Figure 2 After the equipment is started, the servo motor 512 fixed on the side plate 51 starts to work, driving the sprocket 511 directly connected to its output shaft to rotate. Since the two sprockets 511 on the same side are rigidly connected by the transmission shaft 5112, the transmission shaft 5112 ensures that the corresponding sprockets 511 on both sides can rotate synchronously. The rotation of the sprocket 511 drives the chain 5111 meshing with it to move. Since multiple sets of templates 4 are evenly and fixedly installed between two parallel and synchronously running chains 5111, the movement of the chain 5111 is transformed into the cyclic stepping movement of all templates 4 along the preset closed track. Therefore, the transfer structure of all templates 4 not only meets the automation requirements of continuous cyclic production, but also ensures the stability at the moment of pressing. At this time, the stability is achieved together with the mold base. The structure design is ingenious.

[0042] The start and stop of the servo motor 512 enable the chain 5111 to move intermittently at a set rhythm. Each time it starts, the chain 5111 drives the template 4 forward by a fixed station spacing, so that the template 4, which was originally in the loading / preparation position, moves to the pressing station (between the mold base 3 and the upper mold 2). The template 4 that has been pressed is then moved out of the pressing station and enters the subsequent unloading and reset area to prepare for the next round of loading. Therefore, it is only necessary to control the alignment accuracy of the template 4 and the pressing station along the transmission direction of the chain 5111.

[0043] This cycle repeats continuously, enabling multiple sets of templates 4 to circulate automatically and continuously between the three main workstations of "material preparation → pressing and forming → unloading and resetting", providing a foundation for the continuous and efficient operation of the entire pressing equipment.

[0044] like Figures 2-6 Each set of templates 4 includes several mounting plates arranged at intervals along the length of the template base 3, and each mounting plate is provided with a concave mold 41 and a pad 42. The concave mold 41 is used to place the pressure ring 61, and the pad 42 is used to place the fiber optic connector 62. When each mounting plate in a set of templates 4 is located directly above the template base 3, the template base 3 and the concave mold 41 are vertically aligned. The concave molds 41 on each mounting plate are of different sizes. By using concave molds 41 of different sizes, pressure rings 61 of different specifications can be adapted. The snap-fit ​​mechanism includes a vertical plate 43 and a fixed plate 44 respectively set on each mounting plate. The fixed plate 44 is located below one side of the vertical plate 43. At this time, the fixed plate 44 and the vertical plate 43 are arranged in an L-shape. Each fixed plate 44 is provided with a pressing module. The pressing module is used to press the fiber optic cable 6 against the vertical plate 43. After the pressing is completed, the pressing module pushes the fiber optic cable 6 away from the vertical plate 43 and pushes the pressure ring 61 and the fiber optic connector 62 off the concave mold 41 and the pad 42.

[0045] The pressing module includes a rotating mechanism, a pressure roller 4411, and a linear drive. The linear drive drives the pressure roller 4411 to approach the upright plate 43, pressing the optical fiber 6 against one side of the upright plate 43. The optical fiber 6 is parallel to the axis of the pressure roller 4411. When the pressing is completed and the template 4 circulates to the bottom of the mold base 3, the rotating mechanism drives the pressure roller 4411 to rotate, causing the pressure roller 4411 to push the optical fiber 6 out between the upright plate 43 and the pressure roller 4411. The rotating mechanism includes a rotating shaft 4412 coaxially mounted on the pressure roller 4411, and a gear 4413 is provided on the rotating shaft 4412. A rack 5131 that meshes with the gear 4413 is mounted on the side plate 51 via a mounting component. When the pressing is completed and the template 4 circulates to the bottom of the mold base 3, the gear 4413 meshes with the rack 5131. Then, as the template 4 moves, the gear 4413 drives the pressure roller 4411 to rotate through the rotating shaft 4412 via the meshing of the gear 4413 and the rack 5131. Several anti-slip rings are coaxially provided on the pressure roller 4411, and the anti-slip rings are distributed at intervals along the axis of the pressure roller 4411. The anti-slip rings reduce the slippage between the pressure roller 4411 and the optical fiber 6 when the pressure roller 4411 rotates.

[0046] The mounting component is an L-shaped mounting bracket 513, which is located at the bottom end of the side plate 51 near the gear 4413. The rack 5131 is located at the bottom end of the mounting bracket 513. The linear drive component includes a tension spring 47, a slide block 441, and a connecting groove 45 located at the top of the mounting plate. The slide block 441 is horizontally slidably connected to the fixed plate 44, and the pressure roller 4411 is rotatably connected to the slide block 441. The bottom end of the slide block 441 is provided with a vertical plate 4414, which is vertical. The bottom end of plate 4414 passes through the connecting groove 45 and extends to the bottom of the mounting plate. The bottom end of the mounting plate is provided with a suspension plate 46, and a tension spring 47 is provided between the suspension plate 46 and the vertical plate 4414. When all the mounting plates in a set of templates 4 are located directly above the mold base 3, the suspension plate 46, the vertical plate 4414 and the tension spring 47 are all located on one side of the mold base 3. At this time, the mold base 3 will not affect the suspension plate 46, the vertical plate 4414 and the tension spring 47 from moving with the mounting plate.

[0047] like Figures 2-8 The process of the template and the clamping module working together is as follows:

[0048] Step 1: Clamping Preparation

[0049] According to the specifications of the clamping ring 61, select the corresponding size of the concave mold 41 on each mounting plate of the template 4. Place the clamping ring 61 into the concave mold 41, place the fiber optic connector on the pad 42, and place the fiber optic cable 6 on the side of the upright plate 43. Then, press the fiber optic cable 6 radially between the upright plate 43 and the pressure roller 4411, forcing the pressure roller 4411 to retract and stretch the tension spring 47. The rebound force of the tension spring 47 is used to achieve stable clamping, effectively preventing the fiber optic cable 6 from falling off the clamping ring 61 due to dragging during subsequent movement or crimping.

[0050] Step 2: Press forming

[0051] When the template 4 is transported to the top of the mold base 3, the electric cylinder 112 drives the upper mold 2 to press down. The upper mold 2 cooperates with the lower mold composed of the mold base 3 and the concave mold 41, and squeezes the pressure ring 61 to plastically deform it, thereby pressing and fixing the optical fiber 6 to the connector.

[0052] Step 3: Rotary unloading

[0053] After crimping is completed, the upper mold 2 rises and resets, and the chain 5111 drives the template 4 to leave the crimping station (mold base 3) and move downstream. When the template 4 moves to the bottom of the mold base 3, the template 4 is located below the support platform 31, and the gear 4413 on the rotating shaft 4412 and the stationary rack 5131 on the mounting bracket 513 begin to mesh. As the template 4 continues to move, the stationary rack 5131 forces the gear 4413 to rotate. The rotation of the gear 4413 directly drives the pressure roller 4411 to rotate around its own axis through the rotating shaft 4412. The rotating pressure roller 4411 generates tangential friction between itself and the still-clamped optical fiber 6. This friction pushes the optical fiber 6 (along with the crimped connector) downward from the clamping opening between the upright plate 43 and the pressure roller 4411, reducing the situation where the pressure ring 61 is stuck in the concave mold 41 and cannot fall off under gravity. After being pushed out, the workpiece falls to the bottom plate 1 under gravity, completing the automatic unloading. By using gear 4413 and rack 5131 to drive the pressure roller 4411 to rotate, the optical fiber 6 is forcibly pushed out of the clamping port and falls off by gravity. This design avoids the use of additional cylinders, motors, or complex electronic control systems for unloading, reducing costs and control complexity, and improving reliability. It resolves the contradiction that the optical fiber 6 needs to be clamped during crimping but loosened during unloading, using the frictional force of the rotating pressure roller 4411 to forcibly overcome the spring force and "spin out" the optical fiber 6.

[0054] Step 4: Reset and wait for materials

[0055] After the template 4 has completely passed through the rack 5131 segment, the gear 4413 disengages from the rack 5131, and the pressure roller 4411 stops rotating. At the same time, since the optical fiber 6 has been pushed out, the tension spring 47 begins to pull the slide block 441 along with the pressure roller 4411 horizontally towards the vertical plate 43 through the vertical plate 4414, returning to the initial position and preparing for the next work cycle.

[0056] like Figure 3 A right-angled triangular connecting plate 48 is provided at the angle between the fixed plate 44 and the upright plate 43, and the inclined surface of the connecting plate 48 is an arc-shaped surface adapted to the pressure roller 4411. The arc-shaped surface on the connecting plate 48 can reduce the situation where the optical fiber 6 slides into the lower side of the pressure roller 4411 when it is pressed between the upright plate 43 and the pressure roller 4411, which would prevent the optical fiber 6 from being pushed out when the pressure roller 4411 rotates.

[0057] like Figures 2-4The upper mold 2 is equipped with a positioning mechanism. When each mounting plate in a set of templates 4 is located directly above the mold base 3 and the upper mold 2 is pressed down, the positioning mechanism is used to position the mounting plates on the mold base 3. The positioning mechanism includes several positioning rods 21 and inserts 49 on each mounting plate in each set of templates 4. When the upper mold 2 is pressed down, the upper mold 2 drives each positioning rod 21 to move downward, so that the bottom end of each positioning rod 21 is inserted into each insert 49 respectively. The bottom end face of each positioning rod 21 is a pointed tip.

[0058] like Figures 2-4 The positioning mechanism works as follows, and its core function is to achieve positioning before crimping to ensure crimping quality:

[0059] When a set of templates 4 is driven by the circulation mechanism, causing the mounting plates on them to move to the pressing station directly above the mold base 3, the extrusion mechanism begins to drive the upper mold 2 to press down. In the initial stage of the downward movement of the upper mold 2, several positioning rods 21 fixedly installed on it also move down synchronously. Since the bottom end face of the positioning rod 21 is constructed as a pointed tip, this design gives it good guiding properties. When the positioning rod 21 approaches the corresponding insert 49 on the mounting plate, even if there is a slight initial alignment deviation between the template 4 and the upper mold 2, the pointed tip can easily guide and correct the position, ultimately ensuring that the bottom ends of each positioning rod 21 can smoothly... The positioning rod 21 is precisely inserted into each of the insert barrels 49. After the positioning rod 21 is inserted into the insert barrel 49, it essentially forms a rigid constraint in the horizontal direction, locking the upper mold 2 and the template 4 (mounting plate) into a whole before pressing. This reduces lateral displacement or shaking and provides crucial precision assurance for subsequent pressing actions, thereby ensuring the accuracy of the pressing and forming position and effectively reducing pressing defects caused by misalignment. After pressing is completed, the upper mold 2 drives the positioning rod 21 to rise, causing it to exit from the insert barrel 49 and release the constraint on the template 4. The template 4 can then move out of the station under the drive of the circulation mechanism and enter the next cycle.

[0060] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
