[0030] Compared with the prior art, the present invention has the following beneficial technical effects:

[0031] A device for bidirectional adjustment of an optical fiber bundle disclosed by the present invention includes a horizontal adjustment plate, an intermediate plate, a vertical adjustment plate, and a mold base support. The intermediate plate is arranged between the horizontal adjustment plate and the vertical adjustment plate. The horizontal adjustment plate and the intermediate plate are connected by a horizontal adjustment bolt. The vertical adjustment plate and the intermediate plate are connected by a vertical adjustment bolt; Rotate the horizontal adjustment bolt. The vertical adjustment plate is driven by the intermediate plate to move horizontally.

[0055] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0056] As Figure 1 shown, a device for bidirectional adjustment of an optical fiber bundle disclosed by the present invention includes a mounting die base and a die base bracket 1 for fixedly mounting the mounting die base. The mounting die base includes a horizontal adjustment plate 2, an intermediate plate 3, and a vertical adjustment plate 4. The horizontal adjustment plate 2 is mounted on the die base bracket 1. The intermediate plate 3 is disposed between the horizontal adjustment plate 2 and the vertical adjustment plate 4. The horizontal adjustment plate 2 is connected to the vertical adjustment plate 4 through the intermediate plate 3. The intermediate plate 3 horizontally slides relative to the horizontal adjustment plate 2 through a horizontal guiding structure, and the vertical adjustment plate 4 vertically slides relative to the intermediate plate 3 through a vertical guiding structure.

[0057] The horizontal sliding described in the present invention is Figure 1 the front-back sliding in the orientation shown in Figure 1 and the vertical sliding is the up-down sliding in the orientation shown in

[0058] As Figure 2 shown, a positioning hole 41 is opened at the upper central position of the vertical adjustment plate 4. A ceramic die 7 is installed in the positioning hole 41. By adjusting the horizontal and vertical positions of the vertical adjustment plate 4, the central position of the ceramic die 7 is kept in good coaxiality with the central position of the machine head.

[0059] More preferably, as Figure 2 shown, a reflector mounting bracket 5 and a laser mounting bracket 6 are installed on the vertical adjustment plate 4. Both the reflector mounting bracket 5 and the laser mounting bracket 6 are L-shaped plates. Long strip holes are opened on the side plate where the L-shaped plate is connected to the vertical adjustment plate 4 for adjusting the up-down position. Mounting holes are opened on the other side plate, and a region reflection type laser sensor for reflecting the corresponding mounting reflector and detection optical fiber is installed through a fastening bolt 15. This laser sensor belongs to a reflection type laser sensor and is used to detect the optical fiber, so as to judge whether the optical fiber is broken or whether the production is normal.

[0060] The horizontal guiding mechanism and the vertical guiding mechanism have the following four ways:

[0061] The first one:

[0062] As Figure 2 shown, adjacent plates are connected by keys. Specifically, the horizontal guiding mechanism uses a horizontal key 8, and the vertical guiding mechanism uses a vertical key 9. As Figure 5 and 6 shown, a horizontal hole 34 is opened on one side surface of the intermediate plate 3, and a vertical hole 33 is opened on the other side surface. The horizontal hole 34 and the vertical hole 33 are in a "cross" shape. As Figure 3 shown, a horizontal guiding hole 21 is opened on the horizontal adjustment plate 2. As Figure 7As shown in the figure, a vertical guiding hole 43 is formed in the vertical adjusting plate 4; half of the horizontal key 8 is embedded in the horizontal hole 34, and the other half is embedded in the horizontal guiding hole 21; half of the vertical key 9 is embedded in the vertical hole 33, and the other half is embedded in the vertical guiding hole 43. The key connection can not only ensure relative sliding, but also connect adjacent plates. This solution is the optimal solution.

[0063] Preferably, the horizontal key 8 and the vertical key 9 are fixed to the intermediate plate 3 by key fixing bolts 13. The horizontal hole 34 matches the size of the horizontal key 8. In the horizontal direction, the length of the horizontal guiding hole 21 is greater than the length of the horizontal key 8; the vertical hole 33 matches the size of the vertical key 9. In the vertical direction, the length of the vertical guiding hole 43 is greater than the length of the vertical key 9. The horizontal key 8 slides horizontally in the horizontal guiding hole 21, thereby driving the intermediate plate 3 to slide horizontally, and the intermediate plate 3 drives the vertical adjusting plate 4 to slide horizontally; the vertical guiding hole 43 moves up and down along the vertical key 9, that is, the vertical adjusting plate 4 slides up and down relative to the intermediate plate 3.

[0064] Alternatively, the horizontal key 8 is fixed to the horizontal adjusting plate 2. The horizontal guiding hole 21 matches the size of the horizontal key 8. In the horizontal direction, the length of the horizontal hole 34 is greater than the length of the horizontal key 8; the horizontal hole 34 moves horizontally along the horizontal key 8, that is, the intermediate plate 3 slides horizontally, and the intermediate plate 3 drives the vertical adjusting plate 4 to slide horizontally.

[0065] The vertical key 9 is fixed to the vertical adjusting plate 4. The vertical guiding hole 43 matches the size of the vertical key 9. In the vertical direction, the length of the vertical hole 33 is greater than the length of the vertical key 9. The vertical key 9 moves up and down in the vertical guiding hole 43, that is, the vertical adjusting plate 4 slides up and down relative to the intermediate plate 3.

[0066] Second:

[0067] As Figure 9 shown in the figure, both the horizontal guiding structure and the vertical guiding mechanism adopt a guiding column mechanism, including a first guiding column 18 and a second guiding column 19; a horizontal guiding hole 21 serving as a guide rail is formed in the horizontal adjusting plate 2, and a vertical guiding hole 43 serving as a guide rail is formed in the vertical adjusting plate 4;

[0068] The first guiding column 18 is installed on the side of the intermediate plate 3 opposite to the horizontal adjusting plate 2. The first guiding column 18 is embedded in the horizontal guiding hole 21, and the first guiding column 18 moves back and forth in the horizontal guiding hole 21 along the horizontal direction;

[0069] The second guiding column 19 is installed on the side of the intermediate plate 3 opposite to the vertical adjusting plate 4. The second guiding column 19 is embedded in the vertical guiding hole 43, and the second guiding column 19 moves up and down in the vertical guiding hole 43 along the vertical direction.

[0070] Specifically, both the first guiding column 18 and the second guiding column 19 are connected to the intermediate plate 3 through a connecting shaft.

[0071] More preferably, there are two first guiding columns 18 and two second guiding columns 19, which provide better guiding performance and more stable movement.

[0072] The third type:

[0073] As Figure 11 shown, both the horizontal guiding structure and the vertical guiding mechanism adopt a guide rail roller mechanism, including a first roller 51 and a second roller 52; a horizontal guiding hole 21 serving as a guide rail is formed in the horizontal adjusting plate 2, and a vertical guiding hole 43 serving as a guide rail is formed in the vertical adjusting plate 4;

[0074] The first roller 51 is installed on the side of the intermediate plate 3 opposite to the horizontal adjusting plate 2. Half of the first roller 51 is embedded in the horizontal guiding hole 21, and the first roller 51 rolls back and forth in the horizontal guiding hole 21 along the horizontal direction;

[0075] The second roller 52 is installed on the side of the intermediate plate 3 opposite to the vertical adjusting plate 4. Half of the second roller 52 is embedded in the vertical guiding hole 43, and the second roller 52 rolls up and down in the vertical guiding hole 43 along the vertical direction.

[0076] Specifically, as Figure 12 and 13 shown, a horizontal hole 34 and a vertical hole 33 are formed in the intermediate plate 3, and the horizontal hole 34 and the vertical hole 33 are in a "cross" shape; first grooves 37 for installing the first roller 51 are formed at both ends of the horizontal hole 34, and second grooves for installing the second roller 52 are formed at both ends of the vertical hole 33 except for the accusation 33. The first roller 51 is installed in the first groove 37 through a connecting shaft, and the second roller 52 is installed in the second groove 38 through a connecting shaft.

[0077] More preferably, there are two first rollers 51 and two second rollers 52, which provide better guiding performance and more stable movement.

[0078] The fourth type:

[0079] The guiding structure can also adopt a gear and rack mechanism, specifically including a first gear, a first rack, a second gear and a second rack. A horizontal hole 34 is formed on one side surface of the intermediate plate 3, and a vertical hole 33 is formed on the other side surface. The horizontal hole 34 and the vertical hole 33 are in a "cross" shape; a horizontal guiding hole 21 is formed in the horizontal adjusting plate 2, and a vertical guiding hole 43 is formed in the vertical adjusting plate 4; the first gear is installed in the horizontal hole 34 along the horizontal direction, and the first rack is embedded in the horizontal guiding hole 21; the second gear is installed in the vertical hole 33 along the vertical direction, and the second rack is embedded in the vertical guiding hole 43.

[0080] Both the gear and the rack are embedded. Half of the gear is inside the middle plate 3, and the other half is inside the horizontal adjustment plate 2 or the vertical adjustment plate 4, which can reduce the distance between adjacent plates and make the connection more compact and stable.

[0081] The middle plate 3 used in this structure is relatively thick and can accommodate a part of the first gear and the second gear, which will reduce the distance between adjacent plates.

[0082] The corresponding drawing for the fourth structure is not given and reference can be made to Figure 2 , and Figure 2 the key in it is replaced with a gear for local adjustment.

[0083] As Figure 3 and 4 shown, symmetrically arranged first long holes 22 are provided on the horizontal adjustment plate 2. As Figure 7 shown, symmetrically arranged second long holes 42 are provided on the vertical adjustment plate 4; as Figure 5 shown, a first round hole 31 corresponding to the first long hole 22 and a second round hole 32 corresponding to the second long hole 42 are provided on the middle plate 3. The positions of the first round hole 31 and the second round hole 32 are arranged staggeredly; the first long hole 22 and the first round hole 31 are connected by a horizontal locking bolt 12, and the second long hole 42 and the second round hole 32 are connected by a vertical locking bolt 14.

[0084] The first long hole 22 is used for horizontal locking. When the horizontal adjustment plate 2 slides horizontally and is adjusted to the proper position, the horizontal locking bolt 12 is screwed into the middle plate 3 from the first long hole 22 to lock the horizontal adjustment plate 2; the second long hole 42 is used for vertical locking. When the vertical adjustment plate 4 slides vertically and is adjusted to the proper position, the vertical locking bolt 14 is screwed into the middle plate 3 from the second long hole 42 to lock the vertical adjustment plate 4.

[0085] As Figure 2 shown, a convex block is provided on one side wall of the middle plate 3, and a horizontal adjustment screw hole 35 is provided on the convex block; a lug is provided on one side wall of the horizontal adjustment plate 2, and a horizontal adjustment hole 25 is provided on the lug; the horizontal adjustment screw hole 35 and the horizontal adjustment hole 25 are connected by a horizontal adjustment bolt 10. After the horizontal adjustment bolt 10 is screwed into the horizontal adjustment screw hole 35 of the middle plate 3, it is inserted into this hole and fixed with a washer 17 and a circlip 16. When the horizontal adjustment bolt 10 rotates, it will drive the middle plate 3 to produce a horizontal movement relative to the horizontal adjustment plate 2.

[0086] As Figure 5 and 6 shown, a convex block is provided on the lower side wall of the middle plate 3, and a vertical adjustment screw hole 36 is provided on the convex block; as Figure 7As shown in the figure, lugs are provided on the lower side wall of the vertical adjustment plate 4, and vertical adjustment holes 44 are formed in the lugs; the vertical adjustment screw hole 36 and the vertical adjustment hole 44 are connected by a vertical adjustment bolt 11. After the vertical adjustment bolt 11 is screwed into the vertical adjustment screw hole 36, it is inserted into the hole and fixed with a washer 17 and a circlip 16. When the vertical adjustment bolt 11 rotates, it will drive the vertical adjustment plate 4 to move vertically relative to the intermediate plate 3.

[0087] As Figure 10 shown in the figure, annular grooves 111 are formed in the heads of the horizontal adjustment bolt 10 and the vertical adjustment bolt 11. After the horizontal adjustment bolt 10 is screwed into the horizontal adjustment screw hole 35 of the intermediate plate 3, the head is inserted into the horizontal adjustment hole 25. Washers 17 and circlips 16 are installed in the annular groove 111, and the head of the horizontal adjustment bolt 10 is fixed to the horizontal adjustment hole 25 to prevent the horizontal adjustment bolt 10 from slipping off; after the vertical adjustment bolt 11 is screwed into the vertical adjustment screw hole 36, the head is inserted into the vertical adjustment hole 44. Washers 17 and circlips 16 are installed in the annular groove 111, and the head of the vertical adjustment bolt 11 is fixed to the vertical adjustment hole 44 to prevent the vertical adjustment bolt 11 from slipping off.

[0088] During horizontal adjustment, since the horizontal adjustment plate 2 is fixed, when the horizontal adjustment bolt 10 rotates, the horizontal adjustment screw hole 35 on the intermediate plate 3 will move along the axial direction of the horizontal adjustment bolt 10, thereby driving the intermediate plate 3 to move horizontally relative to the horizontal adjustment plate 2.

[0089] During vertical adjustment, since the intermediate plate 3 is fixed, when the vertical adjustment bolt 11 rotates, the vertical adjustment bolt 11 will simultaneously move axially along the vertical adjustment screw hole 36 on the intermediate plate 3, and then drive the vertical adjustment plate 4 to move vertically relative to the intermediate plate 3 through the vertical adjustment hole 44 connected to the head of the vertical adjustment bolt 11.

[0090] As Figure 8 shown in the figure, the die holder support includes a base 101 and a column 102. The column 102 is fixedly connected to the base 101, and a connection hole 103 is formed at the upper end of the column 102. As Figure 3 and 4 shown in the figure, a connecting plate 23 is connected to one side wall of the horizontal adjustment plate 2, and a long strip fixing hole 24 is formed in the connecting plate 23. The long strip fixing hole 24 and the connection hole 103 are fixedly connected by bolts.

[0091] The base 101 can be made of a rectangular steel plate of 200mm×300mm×8mm, and the column 102 can be a square steel pipe of 60mm×60mm. The top of the square pipe should be sealed, and a bottom plate of 40mmx100mm should be welded at the place where the die holder is installed on the upper part of the square steel pipe column 102. The installation holes are through holes and are fully tapped. In addition, there should be reinforcing rib plates when the rectangular steel plate is welded to the square steel pipe.

[0092] The usage method of the present invention includes horizontal adjustment and vertical adjustment, specifically as follows:

[0093] Horizontal adjustment: Loosen the horizontal locking bolt 12, then rotate the horizontal adjustment bolt 10 to drive the vertical adjustment plate 4 to move horizontally through the intermediate plate 3, so that the ceramic mold 7 on the vertical adjustment plate 4 drives the optical fiber bundle passing through it to move horizontally until the process requirements are met. After the horizontal adjustment is completed, tighten the horizontal locking bolt 12 and the horizontal adjustment bolt 10 to relatively fix the intermediate plate 3 and the horizontal adjustment plate 2.

[0094] Vertical adjustment: Loosen the vertical locking bolt 14, then rotate the vertical adjustment bolt 11, and the vertical adjustment plate 4 moves vertically relative to the intermediate plate 3, which can make the ceramic mold 7 drive the optical fiber bundle passing through it to move vertically until the process requirements are met. After the vertical adjustment is completed, finally tighten the vertical locking bolt 14 and the vertical adjustment bolt 11 to relatively fix the intermediate plate 3 and the vertical adjustment plate 4.
