Description

Technical Field

[0001] This utility model relates to the field of fiber splicing machine technology, and in particular to a fiber splicing machine for optical cable splicing. Background Technology

[0002] Fiber optic fusion splicers, also known as optical cable fusion splicers, play a crucial role in the field of optical communication, especially in the construction and maintenance of optical cables. Their main working principle involves melting the two ends of the optical cable by releasing an electric arc, while simultaneously using the collimation principle to smoothly advance the cable, thereby achieving coupling of the optical cable mode field. Used for the construction and maintenance of optical cables in optical communication, their high precision and stability ensure low loss and high reliability in optical cable connections.

[0003] However, traditional fiber fusion splicing machines often require operators to manually rotate, adjust, and operate components during optical cable splicing. This cumbersome process undoubtedly increases the complexity of operation and reduces overall work efficiency. Therefore, this invention proposes a fiber fusion splicing machine for optical cable splicing. Utility Model Content

[0004] The purpose of this invention is to provide a fiber splicing machine for optical cable splicing, thereby solving the problems mentioned above.

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

[0006] This utility model discloses a fiber splicing machine for optical cables, comprising a base box. Clamping assemblies are symmetrically arranged on the upper left and right sides of the base box. The bottom of each clamping assembly passes through the upper surface of the base box and connects to a movable assembly. The movable assembly is located at the bottom of the base box and mounted on a support frame. A through hole is provided on the upper surface of the base box for the movable assembly to move left and right. A column is provided on one side of each clamping assembly. Mounting plates are provided on opposite surfaces of the left and right columns. An L-shaped rod is slidably mounted on the bottom of the mounting plate away from the column, and a stop is provided at the end of the L-shaped rod. The mounting plate has a counterweight on the side away from the clamping assembly; a mounting base is provided on the upper surface of the mounting plate, and a roller is provided on the mounting base; limit posts are symmetrically provided on the left and right sides of the upper surface of the base box, and a roller matching the roller is provided on the limit post; a limit hole is provided below the roller, and an L-shaped rod is slidably provided in the limit hole; a soft rope is provided at the upper end of the L-shaped rod, and the soft rope passes through the roller and the roller and connects to the clamping assembly; a fiber bonding seat is symmetrically provided at the center of the base box.

[0007] Preferably, the bottom of the base box is symmetrically provided with several support columns.

[0008] Preferably, the moving component includes a gear disposed at the center of the upper end face of the support frame, the gear being symmetrically meshed with a rack, a pulley being disposed at the bottom of the rack, a slide rail being slidably disposed at the bottom of the pulley, and the slide rail being disposed on the support frame; a connecting post being disposed on the upper end face of the rack and connected to the clamping component.

[0009] Preferably, a motor is provided at the center of the lower end face of the support frame, and the output end of the motor passes through the support frame and is connected to the gear.

[0010] Preferably, the clamping assembly includes an upper clamping plate and a lower clamping plate symmetrically distributed vertically, and the upper clamping plate is connected to the lower clamping plate through a lifting assembly.

[0011] Preferably, the lifting assembly includes a lifting screw, the bottom of which is rotatably mounted on the lower clamping plate, the lifting screw is threadedly connected to the upper clamping plate, and a handle is provided at the top of the lifting screw; a limit assembly is provided between the upper and lower clamping plates.

[0012] Preferably, the limiting component includes a guide rod disposed on the upper surface of the lower clamping plate, and the other end of the guide rod extends out of the upper clamping plate and is provided with an absorptive ring.

[0013] Preferably, the upper clamping plate and the lower clamping plate have matching arc grooves on their opposite surfaces.

[0014] Preferably, a guide block is provided on the lower end surface of the mounting plate to restrict the up-and-down movement of the L-shaped rod.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This utility model relates to a fiber optic cable splicing machine. Firstly, a moving component is incorporated: after the fiber optic cable is fixed, a control motor drives a gear to rotate. As the gear rotates, two racks slide towards each other, causing the clamping components on the connecting column to move closer together, thus splicing the two fiber optic cables. After splicing, the fiber optic cables are fused together by a fusion splicing seat. The moving component drives the clamping components to move in opposite directions, reducing the workload of manual adjustment. Secondly, a baffle limits the lateral distance of the fiber optic cable. Through the connection between the soft rope and the L-shaped plate, the clamping components automatically release the obstruction of the fiber optic cable during movement, completing the splicing. The weight of the counterweight naturally moves the L-shaped rod downwards, preparing for the next clamping and positioning. Finally, the design of the upper and lower clamping plates and the arc groove ensures that the fiber optic cable is precisely clamped and positioned in the center, guaranteeing the accuracy of the splicing and making it suitable for different specifications and types of fiber optic cables. In summary, this utility model of a fiber optic cable splicing machine is simple to operate, provides precise splicing, and improves splicing efficiency. Attached Figure Description

[0025] like Figure 1-4 As shown, a fiber splicing machine for optical cables includes a base box 1. Clamping assemblies 6 are symmetrically mounted on the upper surface of the base box 1. The bottom of each clamping assembly 6 passes through the upper surface of the base box 1 and is connected to a moving assembly 4. The moving assembly 4 is located at the bottom of the base box 1 and mounted on a support frame 3. A through hole 5 is provided on the upper surface of the base box 1 for the moving assembly 4 to move left and right. Specifically, in this embodiment, the length of the through hole 5 is greater than the stroke of the moving assembly 4.

[0026] A column 7 is installed on one side of the clamping assembly 6. Mounting plates 8 are installed on the opposite surfaces of the left and right columns 7. An L-shaped rod 9 is slidably mounted on the bottom of the mounting plate 8 away from the column 7. A baffle 10 is installed at the end of the L-shaped rod 9. The axis of the baffle 10 overlaps with the axis of the clamping assembly 6 before it is moved by the moving assembly, thus preventing the left and right clamping assemblies 6 from being spliced. A counterweight 17 is installed on the side of the baffle 10 away from the clamping assembly 6. When the clamping assembly 6 is reset, the L-shaped rod 9 moves downwards and resets under the weight of the counterweight 17. A mounting base 11 is mounted on the upper surface of the mounting plate 8. A roller 12 is mounted on the mounting base 11. Limiting posts 13 are symmetrically mounted on the left and right sides of the upper surface of the base box 1. A roller 14 matching the roller 12 is mounted on the limiting post 13. A limiting hole is opened below the roller 14, and the L-shaped rod 9 is slidably mounted in the limiting hole. A soft rope 15 is fixedly connected to the upper end of the L-shaped rod 9. The soft rope 15 passes through the roller 12 and the roller 14 in sequence and is connected to the clamping assembly 6. A guide block 16 is mounted on the lower surface of the mounting plate 8 to restrict the up and down movement of the L-shaped rod 9. Specifically, the clamping assembly 6 moves towards each other under the drive of the moving assembly 4, the soft rope 15 drives the L-shaped rod 9 to move upward, and the guide block 16 ensures that the L-shaped rod 9 moves upward along the vertical direction. When the L-shaped rod 9 moves upward, the baffle 10 at its end moves upward, thereby exposing the cables to be welded on the left and right sides, preparing for the next step of welding.

[0027] The base box 1 has symmetrically installed fiber splicing seats 2 at its center position for splicing optical cables.

[0028] Several support columns 18 are symmetrically installed at the bottom of the base box 1 to provide support.

[0029] The moving component 4 includes a gear 42 mounted at the center of the upper surface of the support frame 3. The gear 42 is symmetrically meshed with a rack 43. A pulley 46 is mounted on the bottom of the rack 43, and a slide rail 44 is slidably mounted on the bottom of the pulley 46. The slide rail 44 is mounted on the support frame 3. The pulley 46 slides on the slide rail 44, which can effectively reduce the contact area, thereby reducing friction and extending service life. A connecting post 45 connected to the clamping component 6 is mounted on the upper surface of the rack 43. Through the rotation of the gear 42, the rack 43 moves towards (away from) each other. Under the limiting action of the pulley 46 and the slide rail 44, the connecting post 45 moves laterally horizontally, thereby realizing the towards (away from) movement of the clamping component 6, completing the welding operation (the reset operation after welding).

[0030] A motor 41 is installed at the center of the lower end face of the support frame 3. The output end of the motor 41 passes through the support frame 3 and is connected to the gear 42. The motor 41 drives the rotation of the gear 42. In this embodiment, the motor 41 is a forward and reverse reversible motor.

[0031] The clamping assembly 6 includes an upper clamping plate 62 and a lower clamping plate 61 symmetrically distributed vertically. The upper clamping plate 62 is connected to the lower clamping plate 61 via a lifting assembly. The lifting assembly includes a lifting screw 63, the bottom of which is rotatably mounted on the lower clamping plate 61. The lifting screw 63 is threadedly connected to the upper clamping plate 62, and a handle 67 is mounted on the top of the lifting screw 63. A limiting assembly is installed between the upper clamping plate 62 and the lower clamping plate 61. The limiting assembly includes a guide rod 64 mounted on the upper surface of the lower clamping plate 61. The other end of the guide rod 64 extends out of the upper clamping plate 62 and is fitted with a suction ring 65. Specifically, according to the screw principle, under the guiding and limiting effect of the guide rod 64, by rotating the handle 67, the lifting screw 63 rotates forward (reverse), driving the upper clamping plate 62 to move upward (downward) relative to the lower clamping plate 61, thereby clamping the cable to be fused (releasing the cable after fusion), and assisting in completing the fusion process (preparing for the next fusion operation).

[0032] The upper clamping plate 62 and the lower clamping plate 61 have matching arc grooves 66 on their opposite surfaces, which allows the optical cable to be accurately clamped and positioned in the center, ensuring the accuracy of the optical cable connection and making it suitable for optical cables of different specifications and types.

[0033] The operation process of this utility model is as follows:

[0034] First, ensure that the upper and lower clamps are separated, and place the two optical cables to be connected into the arc grooves 66 on the left and right symmetrical clamping components 6 respectively. Then rotate the handle 67, and according to the screw principle, the upper clamp 62 moves downward to clamp the cables.

[0035] Then, the motor 41 starts, the gear 42 rotates, and drives the meshing rack 43 to move towards each other. The connecting column 45 also moves towards each other. During the movement, the lower clamping plate 61 moves towards each other. When it moves to a certain distance, the lower clamping plate 61 moves together with the soft rope 15. Under the combined restraint of the roller 12, roller 2 14 and guide block 16, the L-shaped rod 9 moves upward. When the L-shaped rod 9 moves upward, it drives the baffle 10 to move upward, so that the baffle 10 no longer blocks the left and right cables and exposes the fiber fusion base 2.

[0036] Finally, the lower clamp 61 continues to move towards each other until the end of the cable to be fused is placed at the fusion splice holder 2 to meet the fusion requirements. Then the motor 41 stops, and the fusion splice holder 2 fuses the cable.

[0037] After the above welding is completed, the motor 41 starts to rotate in the opposite direction, the holding component 6 is reset under the action of the moving component 3, and the L-shaped rod 9 and the counterweight 17 are reset under their own weight.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
