Description

Technical Field

[0001] This application relates to the technical field of metal processing, and particularly relates to a grooving device for an optical fiber tailstock. Background Art

[0002] The optical fiber tailstock, also known as the tail shank, is a part in an optical fiber connector.

[0003] See Figure 8 , specifically, the optical fiber tailstock is columnar, with a larger diameter at one end and a smaller diameter at the other end. Among them, the end with the larger diameter is adapted to other parts, and a through groove 7 needs to be opened.

[0004] In the related art, a grooving machine is generally used to groove the optical fiber tailstock, but the general grooving machine can only groove one optical fiber tailstock at a time, and the production efficiency is relatively low. Utility Model Content

[0005] In order to improve the production efficiency, this application provides a grooving device for an optical fiber tailstock.

[0006] The grooving device for an optical fiber tailstock provided by this application adopts the following technical solutions:

[0007] A grooving device for an optical fiber tailstock includes a support, a feeding mechanism, a material supporting mechanism, and a cutting mechanism. The feeding mechanism provides materials for the material supporting mechanism, and both the material supporting mechanism and the cutting mechanism are installed on the support;

[0008] The material supporting mechanism includes at least two supporting plates for receiving materials and a horizontal air cylinder for driving the supporting plates to move horizontally. The supporting plate includes a main plate and a sub-plate that can move relative to the main plate. A placement groove for placing materials and capable of opening and closing is formed between the main plate and the sub-plate;

[0009] The cutting mechanism includes at least two cutting machines for grooving materials. At least two cutting machines correspond to at least two supporting plates, and the cutting machines are located above the supporting plates.

[0010] By adopting the above technical solutions, when the grooving device is in use, the feeding mechanism transports the optical fiber tailstock materials to the supporting plates, and then the horizontal air cylinder drives the supporting plates to move, so that the optical fiber tailstock materials are grooved and cut by the cutting machines; since there are at least two supporting plates and at least two cutting machines, at least two cutting machines work simultaneously and cut the optical fiber tailstock materials on at least two supporting plates, so that at least two optical fiber tailstock materials are cut simultaneously, and the production efficiency is relatively high.

[0011] Optionally, the supporting plate further includes a movable air cylinder for driving the sub-plate to move towards or away from the main plate, and the movable air cylinder is fixedly connected to the sub-plate.

[0012] By adopting the above technical solution, the movable cylinder can drive the sub-plate to move. When the fiber tail seat material is cut, the movable cylinder drives the sub-plate to move away from the main plate, and the placement slot is opened, so that the fiber tail seat material in the placement slot can slide out, which is convenient for taking out the fiber tail seat material.

[0013] Optionally, the supporting mechanism further comprises a movable plate, the movable plate is fixedly connected to the horizontal cylinder, and at least two of the supporting plates are mounted on the movable plate.

[0014] By adopting the above technical solution, the supporting plates are all installed on the moving plate. When the horizontal cylinder drives the moving plate to move, all the supporting plates can be driven to move together at the same time, thus saving energy.

[0015] Optionally, the feeding mechanism includes a vibrating feeding plate, a feeding rail connected to the vibrating feeding plate at one end, and a feeding cylinder that drives the material to move downward. The feeding cylinder is located above the other end of the feeding rail, and the piston rod of the feeding cylinder can enter the feeding rail.

[0016] By adopting the above technical solution, during loading, the vibrating loading tray provides the fiber optic tail seat material to the loading guide rail, and the fiber optic tail seat material moves in the loading guide rail until it moves to the other end of the loading guide rail, after which the loading cylinder is started, and the piston rod of the loading cylinder pushes the fiber optic tail seat material in the loading guide rail downward into the supporting plate.

[0017] Optionally, the slotting device further includes a deburring mechanism, which includes a core inserting rod and a vertical cylinder driving the core inserting rod to move in a vertical direction, wherein the vertical cylinder is fixedly connected to the core inserting rod.

[0018] By adopting the above technical solution, when the support plate brings the cut optical fiber tail seat to the unloading station, the vertical cylinder is started, and the core insertion rod moves downward under the drive of the vertical cylinder and rushes into the internal cavity of the optical fiber tail seat, so that the core insertion rod flushes out the burrs inside the optical fiber tail seat.

[0019] Optionally, the main board is inlaid with a first clip at the placement groove, and the sub-board is inlaid with a second clip arranged opposite to the first clip, and the first clip and the second clip form a clamping groove for clamping materials.

[0020] By adopting the above technical solution, when the first clamp and the second clamp are combined, the two notches form a clamping groove for clamping the lower end of the optical fiber tail seat. Through the clamping effect of the first clamp and the second clamp, the optical fiber tail seat is more stable in the placement groove.

[0021] Optionally, the secondary plate is fixedly connected to a first prying piece for removing a first clamping piece adhered thereto, and the first prying piece is arranged obliquely on the secondary plate.

[0022] By adopting the above technical solution, after the main board and the auxiliary board are opened, the first paddle moves together with the auxiliary board. If the fiber optic pigtail holder adheres to the second clip of the auxiliary board, the first paddle can knock the fiber optic pigtail holder off the second clip, thereby enabling the fiber optic pigtail holder to slide out of the placement groove better.

[0023] Optionally, the main board is fixedly connected with a second paddle for knocking off the one adhering to the second clip. The second paddle is inclined on the main board and is arranged relatively parallel to the first paddle.

[0024] By adopting the above technical solution, after the main board and the auxiliary board are opened, the second paddle moves together with the main board. If the fiber optic pigtail holder adheres to the first clip of the main board, the second paddle can knock the fiber optic pigtail holder off the first clip, thereby enabling the fiber optic pigtail holder to slide out of the placement groove better.

[0025] Optionally, the grooving device is further provided with a blowing pipe. The air inlet end of the blowing pipe is connected to a blower, and the air outlet end faces the supporting plate.

[0026] By adopting the above technical solution, when the supporting plate is at the blanking station and the main board and the auxiliary board are opened, the blowing pipe blows air into the opened placement groove, making it easier for the fiber optic pigtail holder to slide out of the placement groove; at the same time, the blowing pipe can also blow away the cut debris and impurities in the placement groove, making the placement groove more stable when loading the fiber optic pigtail holder next time.

[0027] Optionally, the auxiliary board is connected with a limiting rod, and the support is fixedly connected with a limiting backstop corresponding to the limiting rod and capable of blocking the limiting rod.

[0028] By adopting the above technical solution, when the supporting plate is being loaded, the horizontal air cylinder drives the moving plate to move the supporting plate towards the loading station. When the supporting plate is about to reach the loading station, the limiting rod of the auxiliary board abuts against the limiting backstop. By restricting the movement of the auxiliary board through the limiting backstop, the auxiliary board pushes the movable air cylinder away from the main board and remains stationary, while the main board continues to move forward. When the supporting plate reaches the loading station, there will be a certain distance between the main board and the auxiliary board, so that the first clip and the second clip are opened, facilitating the fiber optic pigtail holder to enter the placement groove and the clamping groove.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. When the first clip and the second clip are combined, the two notches form a clamping groove for clamping the lower end of the fiber optic pigtail holder. Through the clamping action of the first clip and the second clip, the fiber optic pigtail holder is more stable in the placement groove;

[0031] 2. After the main board and the auxiliary board are opened, the first paddle moves together with the auxiliary board, and the second paddle moves together with the main board. When the fiber optic ferrule is stuck on the first clip of the main board, the second paddle can flick the fiber optic ferrule off the first clip. When the fiber optic ferrule is stuck on the second clip of the auxiliary board, the first paddle can flick the fiber optic ferrule off the second clip, thus enabling the fiber optic ferrule to slide out of the placement groove better.

[0032] 3. When the pallet is being loaded, the horizontal cylinder drives the moving plate to move the supporting plate towards the loading station. When the supporting plate is about to reach the loading station, the limiting rod of the auxiliary board abuts against the limiting backstop, and the movement of the auxiliary board is restricted by the limiting backstop, causing the auxiliary board to push the movable cylinder away from the main board and remain stationary, while the main board continues to move forward. When the supporting plate reaches the loading station, there will be a certain distance between the main board and the auxiliary board to make the first clip and the second clip open, facilitating the entry of the fiber optic ferrule into the placement groove and the clamping groove.

Detailed implementation manners

[0042] The present application will be further described in detail below with reference to the accompanying drawings.

[0043] An embodiment of the present application discloses a grooving device for an optical fiber tail seat, which is used for grooving the end of the optical fiber tail seat.

[0044] Referring to Figure 1 , the grooving device includes a support 1, a loading mechanism 2, a material supporting mechanism 3 and a cutting mechanism 4, and the material supporting mechanism 3 and the cutting mechanism 4 are both installed on the support 1.

[0045] The loading mechanism 2 includes a vibrating loading tray 21, a loading guide rail 22 and a loading cylinder 23. One end of the loading guide rail 22 is connected to the vibrating loading tray 21, so that the optical fiber tail seat on the vibrating loading tray 21 can enter the loading guide rail 22, and the other end is located below the loading cylinder 23. The piston rod of the loading cylinder 23 can enter the loading guide rail 22 and push the optical fiber tail seat in the loading guide rail 22 downward.

[0046] It should be noted here that after being debugged by the staff, for the optical fiber tail seats entering the loading guide rail 22, the larger-diameter end is upward and the smaller-diameter end is downward.

[0047] Referring to Figure 2 , the material supporting mechanism 3 includes at least two supporting plates 31 and a horizontal cylinder 32. The supporting plates 31 are located below the loading guide rail 22, and the horizontal cylinder 32 drives the supporting plates 31 to move in the horizontal direction. In this embodiment, two supporting plates 31 are provided, and the two supporting plates 31 are arranged at intervals along the movement direction of the horizontal cylinder 32.

[0048] To enable the horizontal cylinder 32 to drive the two supporting plates 31 to move, the material supporting mechanism 3 further includes a moving plate 33. The moving plate 33 is slidably installed on the support 1, and the moving plate 33 is fixedly connected to the piston rod of the horizontal cylinder 32. The two supporting plates 31 are both installed on the moving plate 33, so that the horizontal cylinder 32 can drive the moving plate 33 to move horizontally on the support 1, thereby driving the supporting plates 31 to move.

[0049] Referring toFigure 3 and Figure 4 The supporting plate 31 includes a main plate 311 and a sub-plate 312. The main plate 311 is fixedly connected to the movable plate 33 by screws. The sub-plate 312 can slide on the upper surface of the movable plate 33. A placement groove 313 that can be opened and closed and for placing the optical fiber tail seat is formed between the main plate 311 and the sub-plate 312.

[0050] It is worth noting that the length of the fiber tail seat is greater than the depth of the placement groove 313 , so that when the fiber tail seat is located in the placement groove 313 , the end of the fiber tail seat with a larger diameter protrudes from the supporting plate 31 .

[0051] In order to enable the main plate 311 and the sub-plate 312 to open and close, the supporting plate 31 also includes a movable cylinder 34, which is fixedly mounted on the movable plate 33. The piston rod of the movable cylinder 34 is fixedly connected to the side of the sub-plate 312 away from the main plate 311, so that the movable cylinder 34 can drive the sub-plate 312 to move toward or away from the main plate 311.

[0052] See also Figure 2 The cutting mechanism 4 includes a fixing frame 42 and at least two cutting machines 41. The fixing frame 42 is installed on the support 1. The at least two cutting machines 41 are connected to the fixing frame 42, and the cutting machines 41 are located above the supporting plate 31 through the fixing frame 42. The number of the cutting machines 41 is the same as the number of the supporting plates 31. Therefore, in this embodiment, two cutting machines 41 are provided, and the two cutting machines 41 correspond to the two supporting plates 31.

[0053] The support plate 31 has a loading station and an unloading station. When the support plate 31 is located at the loading station, the placement slot 313 is located directly below the loading cylinder 23, and the piston rod of the loading cylinder 23 moves downward, thereby flushing the fiber tail seat in the loading guide rail 22 into the placement slot 313; then the horizontal cylinder 32 drives the support plate 31 to move, and the fiber tail seat passes through the cutting machine 41 driven by the support plate 31. The blade of the cutting machine 41 passes through the upper end of the fiber tail seat protruding from the support plate 31, so that the end of the fiber tail seat is cut and grooved; then the support plate 31 Move to the unloading station, the movable cylinder 34 is started, and the movable cylinder 34 drives the sub-plate 312 to move away from the main board 311, and the placement groove 313 is opened, and the optical fiber tail seat that loses the clamping of the main board 311 and the sub-plate 312 slides out of the placement groove 313; finally, the movable cylinder 34 drives the sub-plate 312 to move towards the main board 311, and the sub-plate 312 and the main board 311 are abutted, and the horizontal cylinder 32 drives the supporting plate 31 to move toward the upper feeding station, and repeat the above operation.

[0054] Since the fiber tail seat is punched into the placement groove 313 from top to bottom, in order to allow the fiber tail seat to enter the placement groove 313, the diameter of the placement groove 313 will be slightly larger than the diameter of the fiber tail seat, but this makes the fiber tail seat easy to shake in the placement groove 313 when being grooved by the cutting machine 41, resulting in unstable grooves at the upper end of the fiber tail seat.

[0055] See also Figure 4 , Figure 5 and Figure 6 In order to make the optical fiber tail seat more stable in the placement groove 313, the main board 311 is inlaid with a first clamp 314 at the placement groove 313, and the sub-board 312 is inlaid with a second clamp 315 corresponding to the first clamp 314. The first clamp 314 and the second clamp 315 both have notches. When the first clamp 314 and the second clamp 315 are combined, the two notches form a clamping groove 316 for clamping the lower end of the optical fiber tail seat. Through the clamping effect of the first clamp 314 and the second clamp 315, the optical fiber tail seat is more stable in the placement groove 313.

[0056] In order to enable the first clamp 314 and the second clamp 315 to smoothly clamp the optical fiber tail seat, the sub-plate 312 is fixedly connected with a limit rod 317, and the support 1 is fixedly connected with a limit backing 11 corresponding to the limit rod 317. When the support plate 31 is loading, the horizontal cylinder 32 drives the movable plate 33 to move the support plate 31 to the loading station. When the support plate 31 is about to reach the loading station, the limit rod 317 of the sub-plate 312 abuts against the limit backing 11, and the movement of the sub-plate 312 is limited by the limit backing 11, so that the sub-plate 312 pushes the movable cylinder 34 in the direction away from the main plate 311 and remains motionless, while the main plate 311 continues to move forward, so that when the support plate 31 reaches the loading station, the main plate 311 and the sub-plate 312 will be separated by a distance. The distance is such that the first clamp 314 and the second clamp 315 are opened, so that the optical fiber tail seat can enter the placement groove 313 and the clamping groove 316 conveniently; after the optical fiber tail seat enters the placement groove 313, the horizontal cylinder 32 drives the supporting plate 31 to move toward the lower material station, and the limiting rod 317 of the sub-plate 312 no longer abuts against the limiting backer 11. The sub-plate 312 is reset under the action of the movable cylinder 34 and abuts against the main plate 311, and the optical fiber tail seat is firmly clamped in the placement groove 313 by the first clamp 314 and the second clamp 315.

[0057] When the blade of the cutting machine 41 crosses the end of the optical fiber tail seat in a transverse direction, since the optical fiber tail seat is hollow inside, burrs will be left on the edge of the inner cavity after the optical fiber tail seat is slotted.

[0058] See also Figure 7In order to save the staff from the step of deburring, the grooving equipment also includes a deburring mechanism 5, which includes a core insert rod 51 and a vertical cylinder 52. The vertical cylinder 52 is located directly above the unloading station of the support plate 31. The piston rod of the vertical cylinder 52 is fixedly connected to the core insert rod 51, so that the vertical cylinder 52 can drive the core insert rod 51 to move downward.

[0059] When the supporting plate 31 brings the cut optical fiber tail seat to the unloading station, the vertical cylinder 52 is started, and the core insertion rod 51 moves downward under the drive of the vertical cylinder 52 and rushes into the internal cavity of the optical fiber tail seat, so that the core insertion rod 51 removes the burrs inside the optical fiber tail seat; then, the movable cylinder 34 drives the sub-plate 312 to move away from the main plate 311, the placement groove 313 is opened, and the optical fiber tail seat that loses the clamping of the main plate 311 and the sub-plate 312 slides out of the placement groove 313.

[0060] In order to enable the optical fiber tail seat to slide out smoothly from the placement groove 313 after cutting and grooving, the grooving equipment is also provided with a blowing pipe 6 fixedly connected to the support 1, the air inlet end of the blowing pipe 6 is connected to the fan, and the air outlet end faces the unloading station.

[0061] When the supporting plate 31 is at the unloading station and the main plate 311 and the sub-plate 312 are opened, the blowing pipe 6 blows air toward the opened placement slot 313, so that the optical fiber tail seat can slide out of the placement slot 313 more easily; at the same time, the blowing pipe 6 can also blow away the cut debris and impurities in the placement slot 313, so that the placement slot 313 is more stable when it is loaded with the optical fiber tail seat next time.

[0062] See also Figure 4 Since the first clamp 314 and the second clamp 315 directly clamp the fiber tail seat, when the main board 311 and the sub-board 312 are opened, the fiber tail seat may stick to the first clamp 314 or the second clamp 315; in order to allow the fiber tail seat to slide off the first clamp 314 or the second clamp 315 smoothly, the sub-board 312 is fixedly connected with the first paddle 318, and the main board 311 is fixedly connected with the second paddle 319, the first paddle 318 and the second paddle 319 are arranged obliquely on the main board 311, and the first paddle 318 and the second paddle 319 are arranged relatively parallel; and after the main board 311 and the sub-board 312 are combined, the first paddle 318 and the second paddle 319 are respectively located on both sides of the placement groove 313.

[0063] After the main board 311 and the auxiliary board 312 are opened, the first dial 318 moves together with the auxiliary board 312, and the second dial 319 moves together with the main board 311. If the fiber optic ferrule is stuck on the first clip 314 of the main board 311, the second dial 319 can dial the fiber optic ferrule off the first clip 314. If the fiber optic ferrule is stuck on the second clip 315 of the auxiliary board 312, the first dial 318 can dial the fiber optic ferrule off the second clip 315, thereby enabling the fiber optic ferrule to slide out of the placement groove 313 better.

[0064] The implementation principle of the grooving device for a fiber optic ferrule according to an embodiment of the present application is as follows: When the device is started, the fiber optic ferrule moves from the vibrating loading tray 21 to the loading guide rail 22, and is flushed into the placement groove 313 of the supporting plate 31 through the loading cylinder 23. Then, it passes through the cutting machine 41 and is cut and grooved under the drive of the supporting plate 31. Finally, it reaches the unloading station, the main board 311 and the auxiliary board 312 are opened, and the fiber optic ferrule slides out of the placement groove 313.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
