Description

Technical Field

[0001] The invention relates to the technical field of optical fiber fusion splicing, and in particular to a precisely adjustable optical fiber pressure foot support device. Background Art

[0002] Optical fiber is a fiber made of glass or plastic that can be used as a light transmission tool. With the continuous improvement of current technology, the application of polarization-maintaining optical fiber is becoming more and more extensive. In order to cooperate with the fusion splicing of polarization-maintaining optical fiber, it is necessary to accurately align the stress zone of the optical fiber to ensure the alignment degree of the optical fiber fusion position.

[0003] Since the alignment of polarization-maintaining optical fibers requires rotating the optical fibers, and friction is generated between the rotating optical fibers and the V-grooves, the pressure controlled by the pressure foot affects the accuracy of the core alignment. Therefore, the existing fixed pressure foot bracket cannot meet the functional requirements of the optical fiber fusion splicer.

[0004] During the fiber fusion splicing process, the optical fiber is located in the ceramic V-groove, and the fiber optic pressure foot presses the optical fiber on it with a certain pressure. This pressure can constrain the optical fiber in the V-groove and maintain the stable movement of the optical fiber during fusion splicing. When aligning the stress area, the optical fiber needs to be rotated. The pressure of the fiber optic pressure foot will cause friction between the optical fiber and the V-groove. This friction will cause a certain lag in the movement of the optical fiber, resulting in errors in the alignment of the stress area. Therefore, the pressure on the optical fiber needs to be relatively small when rotating the optical fiber, and the pressure on the optical fiber needs to be relatively large when fusion splicing.

[0005] To this end, the inventors have designed and developed a precisely adjustable optical fiber pressure foot support device, which solves the problem of large errors caused by pressure incompatibility during optical fiber rotation. Summary of the Invention

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A precisely adjustable optical fiber pressure foot support device comprises a mounting seat and a V-groove seat, wherein the mounting seat is provided with a motor fixing seat, the motor fixing seat is provided with a side plate, the side plate is provided with a photoelectric switch, the motor fixing seat is provided with a guide bar, a sliding sleeve on the guide bar is provided with an adapter plate, and the adapter plate is provided with a blocking plate that is linked and matched with the photoelectric switch.

[0008] Preferably, a jacking motor is provided on the motor fixing seat, a screw rod is provided at the end of the output shaft of the jacking motor, and a hollow jacking rod that rotates in conjunction with the screw rod is provided on the adapter plate.

[0009] Preferably, a guide groove slidably matched with the guide bar is provided on the adapter plate, and a connecting seat is provided on the adapter plate.

[0010] Preferably, the upper shaft of the connecting seat is connected to an extension bracket, an assembling frame is provided at the end of the extension bracket, and a pressure foot matching the V-groove seat is provided on the bottom surface of the other end of the assembling frame.

[0011] Preferably, a rotating fixed seat is provided on the mounting seat, a rotating motor is provided on the side of the rotating fixed seat, and a driving gear is provided on the end of the output shaft of the rotating motor.

[0012] Preferably, an optical fiber strip is placed on the V-groove seat, and an observation box is provided on the mounting seat.

[0013] Preferably, the rotating fixing seat is provided with a rotating gear for driving the optical fiber strip to rotate, and the rotating gear is meshed and matched with the driving gear.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Through the setting of photoelectric switches and blocking plates, the presser foot is used to drive the assembly frame, extension bracket, connecting seat and adapter plate to move up and down as a whole to adjust the photoelectric signal of the photoelectric switch to be connected and closed, so that the pressure of the assembly of the presser foot and the V-groove seat on the optical fiber strip will be adjusted accordingly.

[0016] 2. By setting up the screw rod and the hollow lifting rod, and utilizing the mutual cooperation between the photoelectric switch and the blocking plate, the opening and closing of the lifting motor can be accurately controlled, so that the pressure of the pressure foot on the optical fiber strip can be adapted, avoiding the situation where the optical fiber strip is subjected to greater or lesser pressure during the rotation process.

[0017] In summary, the present invention overcomes the shortcomings of the existing technology, has a reasonable design, and uses photoelectric signals to control the adjustment of the clamping pressure, so that the pressure on the optical fiber during rotation is moderate and will not cause damage to the optical fiber. It has high social use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] Reference Figure 1-5 A precisely adjustable optical fiber pressure foot bracket device includes a mounting base 1 and a V-groove base 8. The mounting base 1 is provided with a motor fixing base 2, the motor fixing base 2 is provided with a side plate 21, the side plate 21 is provided with a photoelectric switch 201, the motor fixing base 2 is provided with a guide bar 22, the guide bar 22 is slidingly sleeved with an adapter plate 6, and the adapter plate 6 is provided with a blocking plate 603 that is linked and matched with the photoelectric switch 201.

[0028] Specifically, a lifting motor 7 is provided on the motor fixing seat 2, and a screw rod 701 is provided at the end of the output shaft of the lifting motor 7. A hollow lifting rod 602 that rotates with the screw rod 701 is provided on the adapter plate 6. Through the arrangement of the hollow lifting rod 602 and the screw rod 701, the output shaft of the lifting motor 7 is used to drive the hollow lifting rod 602 to rotate, and the depth of the hollow lifting rod 602 screwed into the screw rod 701 can be adjusted to adjust the height of the adapter plate 6 and its upper connecting component.

[0029] Specifically, a guide groove 601 is provided on the adapter plate 6 to slide with the guide bar 22, and a connecting seat 61 is provided on the adapter plate 6. By opening the guide groove 601 and coordinating with the guiding connection of the guide bar 22, the adapter plate 6 will not shake during the overall movement.

[0030] Specifically, an extension bracket 62 is connected to the rotating shaft on the connecting seat 61, an assembling frame 63 is provided at the end of the extension bracket 62, and a presser foot 64 matching the V-groove seat 8 is provided on the bottom surface of the other end of the assembling frame 63. By using the connecting seat 61, the extension bracket 62 and the assembling frame 63, the presser foot 64 can be aligned with the position of the V-groove seat 8, so that the presser foot 64 cooperates with the V-groove seat 8 to clamp the optical fiber strip 10.

[0031] Specifically, a rotating fixed seat 4 is provided on the mounting seat 1, a rotating motor 3 is provided on the side of the rotating fixed seat 4, and a driving gear 31 is provided at the end of the output shaft of the rotating motor 3. The setting of the driving gear 31 can transmit its rotational kinetic energy to the rotating gear 5, so that the rotating gear 5 can drive the optical fiber strip 10 to rotate and adjust the welding position of the optical fiber strip 10.

[0032] Specifically, an optical fiber strip 10 is placed on the V-groove seat 8 , and an observation box 101 is provided on the mounting seat 1 , through which the position status of the optical fiber strip 10 can be observed.

[0033] Specifically, a rotating gear 5 is provided on the rotating fixing seat 4 to drive the optical fiber strip 10 to rotate. The rotating gear 5 is engaged with the driving gear 31. The driving gear 31 provides the rotating gear 5 with a rotating power, so that the rotating gear 5 can drive the optical fiber strip 10 to rotate, so as to adjust the welding position of the optical fiber strip 10.

[0034] Working principle: In the present invention, when the optical fiber fusion splicer processes special optical fibers, the rotating motor 3 is turned on, and the meshing matching between the active gear 31 and the rotating gear 5 is used to drive the optical fiber strip 10 to rotate, making it convenient to observe the optical fiber end face under a microscope. Due to the different diameters of the optical fiber strip 10, the relative position height between the hollow lifting rod 602 and the screw rod 701 is controlled by turning on the lifting motor 7, which plays a height adjustment role on the adapter plate 6, allowing the adapter plate 6, the connecting seat 61, the extension bracket 62 and the assembly frame 63 to be precisely adjusted in the up and down directions, thereby achieving the increase and decrease of the relative position height between the presser foot 64 and the V-groove seat 8, and increasing the precise control between the presser foot 64 and the V-groove seat 8.

[0035] When the presser foot 64 is lifted upward, the blocking plate 603 will move upward with the adapter plate 6, so that the blocking plate 603 is away from the photoelectric switch 201, so that the photoelectric switch 201 is in a connected state. The current generated by it prompts the lifting motor 7 to start operating. The operation of the lifting motor 7 can increase the relative position between the hollow lifting rod 602 and the screw rod 701, so that the adapter plate 6 can move upward along the matching direction of the guide groove 601 and the guide bar 22.

[0036] On the contrary, when the presser foot 64 moves downward, the lifting motor 7 can reduce the relative position between the hollow lifting rod 602 and the screw rod 701, so that the hollow lifting rod 602 can drive the adapter plate 6 to move downward as a whole. At this time, the blocking plate 603 also moves downward until the blocking plate 603 can block the middle of the photoelectric switch 201, cutting off the photoelectric signal between the photoelectric switches 201, and the operation of the lifting motor 7 also stops.
