Description

Technical Field

[0001] The present application belongs to the technical field of optical fiber axis alignment equipment, and specifically relates to a pressing fixture and an axis alignment device. Background Art

[0002] Fiber alignment is a process of placing the light into the U-shaped groove on the bar, and then performing operations such as alignment, glue dispensing, and curing. During the curing operation, the U-shaped groove needs to be filled with shadowless glue. During the filling process, the shadowless glue may squeeze the light out of the U-shaped groove, thereby affecting the subsequent end face coupling and increasing the heat dissipation loss of the optical signal. In order to prevent the optical fiber from floating out of the U-shaped groove due to the filling of shadowless glue, a pin is usually used to press on the optical fiber in the vertical direction. At this time, the vertical pressure on the optical fiber is the gravity of the pin, which will cause more shadowless glue to overflow, causing the optical fiber surface to be contaminated. Utility Model Content

[0003] The technical problem to be solved by the present application is that the existing pin directly presses on the optical fiber, causing a large amount of shadowless glue to overflow, so that the optical fiber surface is contaminated. A pressing fixture and an axis alignment device are provided to reduce the overflow of shadowless glue and avoid contamination of the optical fiber surface.

[0004] The technical solution proposed in this application is:

[0005] A pressing jig, comprising:

[0006] Connecting seat;

[0007] An adjustment seat connected to the connecting seat, and the adjustment seat can adjust the position along a first direction relative to the connecting seat;

[0008] A pressure rod is connected to the adjustment seat so as to be reciprocatably movable along a second direction perpendicular to the first direction, and the pressure rod extends along the second direction. A clamping surface is provided at the end of the pressure rod, and an acute angle is formed between a straight line extending along the second direction and the clamping surface.

[0009] Furthermore, an angle between a straight line extending along the second direction and the pressing surface is 30° to 60°.

[0010] Furthermore, an angle between a straight line extending along the second direction and the pressing surface is 45°.

[0011] Furthermore, the connecting seat has a connecting surface, the connecting surface is perpendicular to the second direction, and the adjusting seat is connected to the connecting surface.

[0012] Furthermore, the connection seat includes a connection plate and a connection block, the connection block is fixedly connected to the connection plate, and the connection block has the connection surface, and the connection surface is connected to the surface of the connection plate.

[0013] Furthermore, the pressing fixture further comprises a locking member, which is connected to the connecting seat and is configured to be controllably movable relative to the connecting seat so as to lock and release the adjusting seat during the movement;

[0014] When the locking member locks the adjustment seat, the adjustment seat is fixed relative to the connecting seat; when the locking member releases the adjustment seat, the adjustment seat can adjust its position relative to the connecting seat along the first direction.

[0015] Furthermore, the adjustment seat is provided with an adjustment hole, which extends along the first direction. One end of the locking member passes through the adjustment hole and is connected to the connecting seat. During the movement of the locking member relative to the connecting seat, the other end of the locking member can abut against or separate from the adjustment seat.

[0016] Furthermore, the pressure rod is provided with a sliding groove extending along the second direction;

[0017] The pressing fixture further includes a limiting member, which is connected to the adjusting seat and partially extends into the sliding groove.

[0018] Furthermore, a connecting hole is formed through the adjusting seat, the pressing rod is slidably arranged in the connecting hole, and the end of the limiting member extends into the sliding groove through the connecting hole.

[0019] An axis alignment device comprises the pressing jig as described above.

[0020] The above-mentioned pressing fixture is used to connect the connection seat with other structures in the axis alignment device, and then the position of the adjustment seat is adjusted according to the position of the optical fiber to ensure that the pressing surface can press the optical fiber during the movement of the pressure rod along the second direction. Since the pressure rod extends and moves along the second direction that is relatively inclined to the vertical direction, when the pressing surface presses on the optical fiber, the vertical pressure on the optical fiber is less than the gravity of the pressure rod, thereby reducing the vertical pressure on the optical fiber, reducing the overflow of the shadowless glue, and avoiding contamination of the optical fiber surface. At the same time, it can also avoid crushing the optical fiber and the bar strips. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] On the one hand, if Figure 1 and Figure 2 As shown, an embodiment of the present application provides a pressing fixture 100 for pressing an optical fiber 200 in an axis-aligning device. The pressing fixture 100 includes a connecting seat 110 , an adjusting seat 120 and a pressing rod 130 .

[0029] The connection seat 110 is used to connect with other structures in the axis alignment device so that the pressing fixture 100 is fixed relative to the optical fiber 200. The adjustment seat 120 is connected to the connection seat 110, and the adjustment seat 120 can adjust the position relative to the connection seat 110 along the first direction. The pressure rod 130 is reciprocatingly connected to the adjustment seat 120 along a second direction perpendicular to the first direction, and the pressure rod 130 extends along the second direction. The end face of the pressure rod 130 is provided with a pressing surface, and the pressing surface is used to contact with the optical fiber 200 to press the optical fiber 200. The angle between the straight line extending along the second direction and the pressing surface is an acute angle.

[0030] It should be noted that, in this embodiment, the pressed portion of the optical fiber 200 extends in the horizontal direction, so the pressing surface is a horizontal surface, and the first direction is Figure 1 The second direction is set to be inclined relative to the vertical direction, such as Figure 1 shown.

[0031] The above-mentioned pressing fixture 100 is used to connect the connecting seat 110 with other structures in the axis alignment device, and then the position of the adjustment seat 120 is adjusted according to the position of the optical fiber 200 to ensure that the pressing surface can press the optical fiber 200 during the movement of the pressing rod 130 along the second direction. Since the pressing rod 130 extends and moves along the second direction that is relatively inclined to the vertical direction, when the pressing surface presses on the optical fiber 200, the vertical pressure on the optical fiber 200 is less than the gravity of the pressing rod 130, so that the vertical pressure on the optical fiber 200 can be reduced without replacing the pressing rod 130, reducing the overflow of the shadowless glue and avoiding contamination of the surface of the optical fiber 200. At the same time, it can also avoid crushing the optical fiber 200 and the bar strips.

[0032] It needs to be further explained that the plane formed by the straight line extending in the second direction and the pressed part of the optical fiber 200 is a plane in the vertical direction. In other words, the projection of the straight line extending in the second direction on the horizontal plane is parallel to the pressed part of the optical fiber 200. In this way, after the pressure rod 130 is pressed on the optical fiber 200, the gravity of the pressure rod 130 can be divided into two components in the vertical direction and the horizontal direction, and the direction of the horizontal component is the length direction of the pressed part of the optical fiber 200.

[0033] In addition, it is necessary to further explain that when aligning multiple optical fibers 200, the multiple optical fibers 200 are arranged at intervals along the first direction, or the aligning device is provided with multiple fixed positions arranged at intervals along the first direction, and each fixed position can be used to place the bar and the optical fiber 200. At this time, the position of the adjustment seat 120 can be adjusted along the first direction to ensure that the pressure rod 130 can correspond to the optical fiber 200, thereby ensuring that the pressure rod 130 can press any optical fiber 200 or any optical fiber 200 at a fixed position.

[0034] Furthermore, the angle between the straight line extending in the second direction and the pressing surface is 30° to 60°, so as to reduce the vertical gravity while ensuring the pressing effect on the optical fiber 200, and prevent the optical fiber 200 from floating and moving. Preferably, the angle between the straight line extending in the second direction and the pressing surface is 45°, at which time the vertical pressure on the optical fiber 200 is equal to the gravity of the pressure rod 130. .

[0035] In one embodiment, the connection seat 110 has a connection surface 111, the connection surface 111 is perpendicular to the second direction, and the adjustment seat 120 is connected to the connection surface 111. It should be noted that the connection method between the connection seat 110 and other structures of the axis alignment device is fixed, and the connection surface 111 is inclined relative to the vertical direction. At the same time, since the connection surface 111 is perpendicular to the second direction, after the adjustment seat 120 is connected to the connection surface 111, it can be ensured that the pressure rod 130 is also inclined relative to the vertical direction, thereby ensuring that the pressing surface is a horizontal surface.

[0036] In one embodiment, the connection seat 110 includes a connection plate 112 and a connection block 113, the connection plate 112 is used to connect with other structures of the shaft alignment device, the connection block 113 is fixedly connected to the connection plate 112, and the connection block 113 has the above-mentioned connection surface 111. Furthermore. The connection surface 111 is connected to the surface of the connection plate 112. In other words, the end of the connection block 113 is connected to the connection plate 112, and the connection surface 111 is the side of the connection block 113. Specifically, the connection plate 112 is connected to other structures of the shaft alignment device by bolts.

[0037] In one embodiment, the pressing jig 100 further includes a locking member, which is connected to the connecting seat 110 and is configured to be controllably movable relative to the connecting seat 110 so as to lock and release the adjusting seat 120 during the movement.

[0038] When the locking member locks the adjustment seat 120 , the adjustment seat 120 is fixed relative to the connecting seat 110 ; when the locking member releases the adjustment seat 120 , the adjustment seat 120 can adjust its position relative to the connecting seat 110 along the first direction.

[0039] Furthermore, the adjustment seat 120 is provided with an adjustment hole 121, which extends along the first direction. One end of the locking member passes through the adjustment hole 121 and is connected to the connecting seat 110. During the movement of the locking member relative to the connecting seat 110, the other end of the locking member can abut against or separate from the adjustment seat 120, thereby locking the adjustment seat 120 when abutting against the adjustment seat 120 and releasing the adjustment seat 120 when separating from the adjustment seat 120.

[0040] It is understandable that the locking member can be a bolt, which is threadedly connected to the connecting seat 110, and the rod of the locking member is staggered with the adjusting seat 120, and the head of the locking member can abut against the adjusting seat 120, so as to lock the adjusting seat 120 when abutting against the adjusting seat 120. In addition, it can be determined that in this embodiment, the adjusting seat 120 can also rotate relative to the connecting seat 110 and rotate around an axis parallel to the second direction to further adjust the position of the pressing rod 130.

[0041] In one embodiment, the pressure rod 130 is provided with a slide groove 131 extending along the second direction, and the pressing fixture 100 also includes a limit member 140, which is connected to the adjustment seat 120, and the limit member 140 partially extends into the slide groove 131 to limit the pressure rod 130 so that the pressure rod 130 moves back and forth along the second direction.

[0042] Specifically, the adjustment seat 120 is penetrated by a connecting hole 122, the pressure rod 130 is slidably disposed in the connecting hole 122, and the end of the limiting member 140 extends into the sliding groove 131 through the connecting hole 122 to limit the pressure rod 130 from rotating in the connecting hole 122, so that the pressure rod 130 reciprocates along the second direction.

[0043] On the other hand, the present application further provides an axis alignment device, which is used to align the optical fiber 200, thereby facilitating the coupling of the optical fiber 200. The axis alignment device includes the pressing fixture 100 in the above embodiment.

[0044] Furthermore, the axis alignment device also includes a mounting frame and a supporting member, the mounting frame and the supporting member are relatively fixedly arranged, the connecting seat 110 is used to connect with the mounting frame, the supporting member is used to carry the optical fiber 200, and the pressure rod 130 can be pressed on the optical fiber 200 carried by the supporting member.

[0045] It should also be noted that the axis alignment device also includes a detection mechanism, which usually includes multiple CCD cameras and multiple CCD light sources to perform multi-angle detection on the optical fiber 200. If the pressure rod 130 extends in the vertical direction, the pressure rod 130 will block the overhead CCD light source located above, so in this application, the pressure rod 130 is arranged to be tilted relative to the vertical direction, which can avoid the pressure rod 130 from blocking the overhead CCD light source, thereby improving the detection accuracy of the pressing position, and further ensuring the axis alignment accuracy of the optical fiber 200.

[0046] In summary, the pressing fixture 100 and the shaft alignment device provided by the present application have at least the following advantages:

[0047] 1. The pressure rod 130 is inclined relative to the vertical direction, which can reduce the vertical pressure, reduce the overflow of the shadowless adhesive, avoid the surface of the optical fiber 200 from being contaminated, and also avoid crushing the optical fiber 200 and the bar strips.

[0048] 2. The adjustment seat 120 can adjust the position, so that the position of the pressure rod 130 can be adjusted according to the position of the optical fiber 200, so that the pressure rod 130 is suitable for pressing the optical fiber 200 at different positions;

[0049] 3. The pressure rod 130 is inclined relative to the vertical direction, which will not block the CCD light source when looking down, thereby improving the detection accuracy and further improving the axis accuracy.

[0050] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
