[0002] With the rapid development of network technology, technologies such as data center interconnection, fiber optic sensing, and next-generation fiber optics are developing rapidly, and various network applications are constantly being upgraded.

[0003] During the production of bundled fiber optic branch ends, a tail tube needs to be fitted onto each branch tube. Currently, the tail tube is fitted onto each branch tube manually. Due to the large number of tail tubes, this work is repetitive, time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic sleeve manufacturing method for optical fiber branch tubes, which automatically sleeves the branch tubes with tail tubes, saves manpower and improves production efficiency.

[0005] The technical solution adopted by the present invention to solve the above problems is: a method for preparing an automatic sleeve for an optical fiber branch tube, the preparation method comprising the following steps:

[0006] Step 1: After aligning the branch pipes, place them into the pipe-laying funnel. The branch pipes are arranged in a row along the height direction of the pipe-laying funnel and fall onto the conveyor belt one by one.

[0007] Step 2: The conveyor belt transports the branch pipes that have fallen onto the conveyor belt to the flattening unit, the acceleration unit, and the straightening unit in sequence; the flattening unit lays the branch pipes flat; the acceleration unit widens the gap between two adjacent branch pipes; the straightening unit straightens the branch pipes on the conveyor belt.

[0008] Step 3: The aligned branch pipe is conveyed to the clamping unit; the clamping unit clamps the branch pipe and transfers it to the sleeve unit;

[0009] Step 4: The sleeve unit places the tail tube onto one end of the branch pipe, completing the automatic sleeve placement of the tail tube onto one branch pipe; then the sleeve unit automatically resets, ready for the next sleeve operation.

[0010] The fabric funnel includes a conical feed bin, the outlet of which is connected to a rectangular fabric bin.

[0011] The distance between the outlet end of the fabric bin and the top surface of the conveyor belt is equal to the diameter of a branch pipe; one end of the branch pipe falling on the conveyor belt extends beyond the edge of the conveyor belt.

[0012] The width of the fabric bin matches the diameter of the branch pipe.

[0013] The flattening unit includes a flattening motor, and a flattening roller assembly is provided on the output shaft of the flattening motor. The acceleration unit includes an acceleration motor, and an acceleration roller assembly is provided on the output shaft of the acceleration motor. The straightening unit includes a straightening motor, and a straightening gear assembly is provided on the output shaft of the straightening motor. The flattening roller assembly, the acceleration roller assembly, and the straightening gear assembly are arranged in parallel above the conveyor belt and are perpendicular to the conveyor belt.

[0014] The backlash of the gears in the centering gear set is equal to the diameter of one branch pipe.

[0015] The clamping unit includes two clamping conveyor belts arranged opposite each other, with the two clamping conveyor belts conveying in opposite directions.

[0016] The sleeve unit includes a base, with a cylinder slot and a push rod slot on the top of the base. The cylinder slot and the push rod slot are interconnected. A sleeve cylinder is installed in the cylinder slot, and a horizontally arranged push rod is installed in the push rod slot. One end of the push rod is fixed to the extension rod of the sleeve cylinder, and the other end of the push rod has a sideways U-shaped groove. A tailpipe support is installed on the base, and a tailpipe placement slot is provided on the tailpipe support. The tailpipe placement slot corresponds to the U-shaped groove. The tailpipe placed in the tailpipe placement slot falls into the U-shaped groove. The sleeve cylinder drives the push rod to approach the branch pipe and sleeve the tailpipe onto the branch pipe.

[0017] The tailpipe storage slot and U-shaped slot are sized to match the tailpipe.

[0018] The alignment unit and the sleeve unit are respectively connected to the photoelectric sensor signal.

[0019] Compared with existing technologies, the advantages of this invention are as follows: A method for automatically sleeves optical fiber branch tubes, wherein branch tubes are arranged in a row along the height direction of a tube-laying funnel and fall one by one onto a conveyor belt. The conveyor belt sequentially transports the branch tubes to a flattening unit, an acceleration unit, and a straightening unit. The flattening unit flattens the branch tubes; the acceleration unit widens the spacing between adjacent branch tubes; the straightening unit straightens the branch tubes so that they are perpendicular to the conveyor belt's transport direction, then clamps the branch tubes with the conveyor belt and transports them backward.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As shown in Figure 1, an automatic fiber optic branch tube sleeve device in this embodiment includes a tube-laying funnel 1, with a conveyor belt 2 positioned below the funnel 1 and perpendicular to it. A flattening unit 3, an acceleration unit 4, and a straightening unit 5 are sequentially arranged along the conveyor belt 2. A clamping unit is connected to the output end of the conveyor belt 2, and the clamping unit includes two clamping conveyor belts 6 arranged vertically opposite to each other, with opposite conveying directions. A sleeve unit is located on one side of the clamping unit. Branch tubes are arranged in a row along the height of the funnel 1 and fall onto the conveyor belt 2 one by one. The conveyor belt 2 sequentially transports the branch tubes to the flattening unit 3, the acceleration unit 4, and the straightening unit 5. The flattening unit 1 flattens the stacked branch pipes that fall onto the conveyor belt; the acceleration unit 4 is used to increase the distance between two adjacent branch pipes; the straightening unit 5 straightens the branch pipes so that the branch pipes are perpendicular to the conveying direction of the conveyor belt 2, and then the clamping conveyor belt 6 clamps the branch pipes and conveys them backward. When passing through the sleeve unit, the sleeve unit puts the tail pipe on the branch pipe, realizing the automatic sleeve of the tail pipe on the branch pipe.

[0031] As shown in Figure 2, the pipe-laying funnel 1 includes a conical feed bin 1.1, the outlet of which connects to a rectangular fabric-laying bin 1.2. Branch pipes are simply aligned and placed into the feed bin 1.1. Under gravity, the branch pipes fall into the rectangular fabric-laying bin 1.2. The width of the fabric-laying bin 1.2 is slightly larger than the diameter of the branch pipes, allowing them to line up in a row along the height of the bin. The distance between the outlet of the fabric-laying bin 1.2 and the conveyor belt 2 is one branch pipe diameter. When the conveyor belt 2 stops, the upper branch pipes are stopped falling by the last branch pipe. The outlet of the fabric-laying bin extends beyond the width of the conveyor belt by approximately 1.5 times the length of the tail pipe, ensuring that one end of the branch pipe falling onto the conveyor belt extends beyond 1.5 times the length of the tail pipe, facilitating subsequent tail pipe fitting.

[0032] As shown in Figures 3, 4, and 5, the flattening unit 3 includes a flattening motor 3.1, with a flattening roller assembly 3.2 on its output shaft. This assembly flattens the stacked branch pipes falling onto the conveyor belt, arranging them in a row along the conveyor belt's transport direction. The acceleration unit 4 includes an acceleration motor 4.1, with an acceleration roller assembly 4.2 on its output shaft. The acceleration motor controls the acceleration roller assembly to rotate faster, thereby increasing the distance between adjacent branch pipes. The straightening unit 5 includes a straightening motor 5.1, with a straightening gear assembly 5.2 on its output shaft. When a branch pipe passes through the straightening gear assembly, it is caught within it, and the gear assembly presses against it, straightening the branch pipe onto the conveyor belt. The flattening roller assembly, acceleration roller assembly, and straightening gear assembly are arranged in parallel. The tooth clearance of the gears in the straightening gear assembly is equal to the diameter of one branch pipe.

[0033] As shown in Figures 6 and 7, the sleeve unit includes a base 9. The top surface of the base 9 has a cylinder groove 9.1 and a push rod groove 9.2, which are connected. A sleeve cylinder 7 is housed in the cylinder groove 9.1, and a horizontally arranged push rod 10 is housed in the push rod groove 9.2. One end of the push rod 10 is fixed to the extension rod of the sleeve cylinder 7, and the other end of the push rod 10 has a horizontally extending U-shaped groove. A vertically arranged tailpipe support 8 is mounted on the base 9. A vertically extending tailpipe storage groove is provided on the tailpipe support 8, corresponding to the U-shaped groove, thus connecting the tailpipe storage groove and the U-shaped groove. The dimensions of the tailpipe storage groove and the U-shaped groove match the dimensions of the sleeve.

[0034] As shown in Figure 8, a method for manufacturing an automatic sleeve for an optical fiber branch pipe includes the following steps:

[0035] Step 1: After aligning the branch pipes, place them into the feed hopper. The branch pipes will fall into the rectangular fabric hopper under the action of gravity, so that the branch pipes are arranged in a row along the height of the fabric hopper and fall onto the conveyor belt one by one.

[0036] Step Two: The conveyor belt sequentially transports the branch pipes onto the conveyor belt to the flattening roller group, the accelerating roller group, and the straightening gear group. The flattening motor drives the flattening roller group to rotate, causing the branch pipes to lie flat on the conveyor belt; the accelerating motor drives the accelerating roller group to rotate, widening the gap between adjacent branch pipes; the straightening motor drives the straightening gear group to rotate, causing the passing branch pipes to be positioned within the tooth gaps, thereby compressing the branch pipes and straightening them on the conveyor belt.

[0037] Step 3: The properly aligned branch pipe is then conveyed to the casing unit via a clamping conveyor belt.

[0038] Step 4: The tailpipe in the tailpipe storage slot falls into the U-shaped groove. The sleeve cylinder pushes the push rod to extend, which moves the tailpipe closer to the branch pipe and sleeves the tailpipe onto one end of the branch pipe, completing the automatic sleeve sleeve of one branch pipe. Then the sleeve cylinder resets, ready for the next sleeve action.

[0039] The centering motor and the sleeve cylinder are used in conjunction with photoelectric sensors. When the photoelectric sensor of the centering unit detects that the branch pipe has reached the centering gear set, the centering motor rotates one tooth pitch. When the photoelectric sensor of the sleeve unit detects the branch pipe in the clamping unit, the sleeve cylinder pushes the tail sleeve towards the branch pipe and sleeves it onto the branch pipe.

[0040] This application has a simple structure and is easy to operate. By cooperating with the clamping unit and the sleeve unit, the tail tube is automatically sleeved onto the branch tube, saving manpower and improving production efficiency.

[0041] In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
