Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber processing, in particular to an optical fiber cutting device. Background Art

[0002] To facilitate transport, transfer, and storage, optical fiber raw materials are typically supplied in long rolls. When used, the fiber is cut using a cutter according to the desired length. Traditional cutters, typically conventional guillotines, lack tangential motion relative to the fiber during cutting, making it difficult to sever larger diameter fibers. Even with variable cutter position, multiple cuts along different radial directions are performed, creating multiple cuts that are then pulled apart. This process is complex, slow, and results in uneven cuts, poor quality, and a high risk of waste. Utility Model Content

[0003] The utility model aims to provide an optical fiber cutting device with high cutting efficiency and good cutting quality.

[0004] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] It can be seen that the optical fiber is clamped by two clamping mechanisms, and the two driving mechanisms B are used to drive the two clamping mechanisms and the optical fiber and the cutting blade to rotate relative to each other. During the rotation, the driving mechanism A is used to push the mounting plate to continuously feed the cutting blade, so that the cutting blade feeds around the optical fiber while cutting, and finally cuts the optical fiber, thereby being able to easily cut large-diameter optical fibers and form continuous smooth incisions at the cut ends of the optical fibers, thereby improving the cutting quality. At the same time, the overall structure is simple, compact, and easy to use.

Preferably, the drive motor B is a servo motor or a stepper motor.

[0009] Furthermore, the clamping mechanism includes a fixed clamping plate and a movable clamping plate. The movable clamping plate is fixed to the fixed clamping plate by screws. The fixed clamping plate is fixed to the output shaft of the drive motor B on the corresponding side. The surfaces of the movable clamping plate and the fixed clamping plate adjacent to each other are each provided with a clamping groove, which cooperates to form a fiber clamping groove. This makes operation simple and convenient, and highly efficient.

[0010] Furthermore, along the length direction, the movable clamping plate is shorter than the fixed clamping plate, and a clearance opening is provided on the outside of the fixed clamping plate between the driving motor B and the end of the movable clamping plate to facilitate the extraction of the optical fiber tail.

[0011] Furthermore, the drive motor B is a hollow shaft motor with a through hole on the output shaft; a connector is provided at one end of the fixed clamp close to the corresponding drive motor B, and the connector is provided with a sleeve hole for sleeve-fitting the output shaft and an avoidance groove for allowing the optical fiber to pass through the through hole.

[0012] Furthermore, the connector is provided with a through hole A and a threaded hole A for fastening the output shaft.

[0013] Furthermore, the drive mechanism A includes an L-shaped frame fixed to the base, a drive motor A fixedly mounted on the L-shaped frame, a threaded rod fixed to the output shaft of the drive motor A, and a nut seat with threads matching the threaded rod; the nut seat is fixed to the mounting plate. This structure is simple and compact, which helps save space.

[0014] Furthermore, guide rails are fixed on both sides of the base along the width direction, and the mounting plate is slidably mounted on the top of the two guide rails through two sliding grooves at the bottom.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4 , as shown in the attached instructions Figure 1As shown in FIG, 01 is the width direction of the optical fiber cutting device, 02 is the length direction of the optical fiber cutting device, and 03 is the height direction of the optical fiber cutting device. The optical fiber cutting device provided by the utility model includes a base 2, a mounting plate 3, and a cutting blade 5. The mounting plate 3 is slidably mounted on the base 2 along the width direction 01 of the optical fiber cutting device. The cutting blade 5 is mounted on the base 2 via a blade holder 21. The base 2 is provided with a drive mechanism A4 for pushing the mounting plate 3 toward the cutting blade 5. Along the length direction 02 of the optical fiber cutting device, clamping mechanisms 7 for clamping the optical fiber are provided on both sides of the mounting plate 3 via drive mechanisms B6. The drive mechanism B6 is used to drive the clamping mechanisms 7 to rotate. The cutting blade 5 is located between the two clamping mechanisms 7. In the height direction 03 of the optical fiber cutting device, the cutting blade 5 can be aligned with the optical fiber clamping groove 75 of the clamping mechanism 7.

[0026] When using this optical fiber cutting device, two clamping mechanisms 7 are used to clamp two parts of the optical fiber in the optical fiber clamping groove 75 respectively. During operation, it is necessary to ensure that the part of the optical fiber located between the two clamping mechanisms 7 is as straight as possible to ensure stability during cutting. Then, the driving mechanism A4 works to push the mounting plate 3 to feed toward the side of the cutting blade 5 until the cutting blade 5 contacts the outer wall of the optical fiber and cuts to the predetermined position inside the optical fiber. Then, the driving mechanisms B6 on both sides work simultaneously to drive the two clamping mechanisms 7 to rotate synchronously, thereby driving the optical fiber to rotate. During the rotation process, the driving mechanism A4 works to push the mounting plate 3 to feed continuously, thereby forming a smooth and continuous incision to cut the optical fiber.

[0027] This optical fiber cutting device utilizes two clamping mechanisms 7 to clamp the optical fiber, utilizes two driving mechanisms B6 to drive the two clamping mechanisms 7 and the optical fiber and the cutting blade 5 to rotate relative to each other, and utilizes the driving mechanism A4 to push the mounting plate 3 to continuously feed toward the cutting blade 5 during the rotation process, so that the cutting blade 5 feeds around the optical fiber while cutting, and finally cuts the optical fiber, thereby being able to easily cut large-diameter optical fibers, and at the same time, a continuous smooth incision can be formed at the cut end of the optical fiber, thereby improving the cutting quality. At the same time, the overall structure is simple and compact, and easy to use.

[0031] The fiber clamping groove 75 allows the optical fiber to be inserted and clamped. The specific clamping method is: place the optical fiber between the fixed clamping plate 71 and the movable clamping plate 72, insert the screw into the through hole B741 on the movable clamping plate 72, and tighten it into the threaded hole B742 on the fixed clamping plate 71, thereby fastening the movable clamping plate 72 to the fixed clamping plate 71 to achieve the clamping of the optical fiber. The operation is simple, convenient and efficient.

The connector 76 is provided with a sleeve hole 77 for sleeve-connecting the output shaft 621 and an avoidance groove 78 for allowing the optical fiber to pass through the through hole 622.

[0034] The optical fiber passes through the through hole 622 and is clamped into the sleeve hole 77 at the avoidance groove 78 and then clamped, which ensures that the optical fiber extends in a straight line and avoids excessive curling and winding of the optical fiber during rotation and cutting. In addition, the avoidance groove 78 is not necessary, and the tail of the optical fiber can be swung out from the give way opening 701.

[0035] Preferably, the connector 76 is provided with a through hole A721 and a threaded hole A722 for fastening the output shaft 621 .
