Description

Technical Field

[0001] This utility model belongs to the field of fiber optic patch cord production technology, specifically relating to an automatic feeding device for the end sheath of the cable. Background Technology

[0002] Fiber optic patch cords, as key passive components for optical signal transmission and connection in optical communication systems, are widely used in data centers, communication base stations, broadcasting and television, industrial control, and other fields. As the optical communication industry develops towards higher speeds, higher densities, and larger scale, the market demand for fiber optic patch cord production capacity continues to increase, while the requirements for its product performance (such as insertion loss and return loss) and structural stability are becoming increasingly stringent.

[0003] In the production process of fiber optic patch cords, the installation of the end sleeve (also known as the power cord protective sleeve) is one of the core preliminary steps. The end sleeve is typically made of elastic insulating material, and its main functions are: firstly, to protect the end connection structure of the fiber optic patch cord from damage caused by external dust, moisture, or mechanical impact; and secondly, to enhance the tensile strength of the fiber optic patch cord end, preventing fiber breakage due to external pulling during subsequent assembly, handling, or use, thereby ensuring the transmission performance and lifespan of the fiber optic patch cord. Therefore, the quality of the end sleeve installation (such as installation accuracy and fit) directly determines the smooth progress of subsequent processes (such as connector assembly and performance testing) and the reliability of the final product.

[0004] However, the current industry practice of attaching end sleeves to fiber optic patch cords still largely relies on manual operation. A typical process involves operators manually picking up a single end sleeve from the hopper, visually locating the pre-set attachment position on the fiber optic cable, and then manually attaching the end sleeve. This manual method is inefficient, cannot meet the demands of large-scale production, and results in high labor costs and poor economic returns. It has become a key bottleneck restricting the automation and large-scale production of fiber optic patch cords. The current manual attachment method for end sleeves in fiber optic patch cord production can no longer meet the industry's needs for automated, efficient, high-quality, and low-cost production. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding device for wire tail sheaths, which aims to solve the technical problem that the wire tail sheath application process in the prior art relies on manual operation. There is a lack of automated equipment in the industry that can automatically feed and transport wire tail sheaths to the preset application position, and cooperate with the optical fiber clamping device to complete the high-precision and rapid application of wire tail sheaths.

[0006] To achieve the above objectives, this utility model provides an automatic feeding device for wire tail sheaths, including a feeding device, a positioning device, a picking device, and a frame. The frame supports the feeding device, the positioning device, and the picking device. The feeding device includes a vibratory feeder, and a feeding plate is connected to the outlet of the vibratory feeder. A feeding channel extending along the length of the feeding plate is provided in the middle of the feeding plate. The feeding channel allows the wire tail sheaths to pass through while restricting their movement direction. A picking part extending along the length of the feeding plate is also provided at the end of the feeding plate away from the vibratory feeder. The feeding section is located in the middle of the side of the feeding plate, and the width of the feeding section is smaller than the maximum diameter of the wire tail sheath. A direct vibration feeder is provided below the feeding plate. A limiting mechanism is provided above the end of the feeding plate adjacent to the feeding section. The limiting mechanism includes a limiting head that can extend and retract relative to the feeding channel. A positioning device is provided above the feeding section that can extend and retract relative to the feeding section. The positioning device includes a telescopic mechanism and a mounting block connected to the telescopic mechanism. The mounting block is arranged adjacent to the feeding section and can be sleeved around the feeding section under the drive of the telescopic mechanism. A feeding device is provided below the mounting block.

[0007] Preferably, the material handling device includes a drive mechanism, which is fixedly disposed on one side of the feeding plate and connected to a mounting plate. The drive mechanism can drive the mounting plate to reciprocate along the length of the feeding plate.

[0008] Preferably, the mounting plate is provided with a rotary cylinder, which is located below the material handling section. The rotary cylinder includes a rotating arm, which can drive the rotating arm to rotate relative to the material handling section.

[0009] Preferably, the rotating arm is equipped with a cylinder gripper. When the cylinder gripper is in the open state, the mounting plate drives the cylinder gripper to move towards the material picking part, so that the material picking part is located in the cylinder gripper. When the cylinder gripper closes, it picks up the wire tail sheath on the material picking part.

[0010] Preferably, the cylinder gripper has a gripping hole that is adapted to the wire tail sheath, so that the cylinder gripper can grip the wire tail sheath while avoiding severe deformation of the wire tail sheath. Below the gripping hole, there is an avoidance groove. The width of the avoidance groove is greater than the width of the material picking part. The avoidance groove prevents the cylinder gripper from gripping the material picking part when it grips the wire tail sheath, thereby ensuring that the cylinder gripper can still move with the mounting plate after gripping the wire tail sheath.

[0011] Preferably, the feeding channel is a U-shaped channel, and the side of the material taking part adjacent to the limiting head is an arc-shaped surface, which extends along the U-shaped channel.

[0012] Preferably, the mounting block is provided with a detection device, which is located above the end of the material taking part away from the feeding plate. The detection device is used to detect whether the end sheath of the wire is delivered in place.

[0013] Preferably, the mounting block has a mating groove at one end adjacent to the material taking part, which is parallel to the material taking part. The opening of the mating groove faces the material taking part, and the width of the mating groove is greater than the maximum diameter of the wire tail sheath. The height of the mating groove is greater than the sum of the maximum diameters of the material taking part and the wire tail sheath. The mating groove allows the mounting block to be fitted around the material taking part.

[0014] Preferably, a stop block is provided at the end of the mating groove away from the feeding plate. When the mounting block is sleeved around the material taking part, the stop block restricts the position of the wire tail sheath.

[0015] Preferably, the top of the mounting block is connected to the telescopic mechanism, the back of the mounting block is provided with a slider and a slide rail, the slider is fixedly connected to the mounting block, the slide rail is fixedly mounted on the frame, and the slider is slidably mounted in the slide rail.

[0016] The above-mentioned technical solutions of one or more technical solutions in the automatic feeding device for thread tail sheaths provided in this embodiment of the utility model have at least one of the following technical effects:

[0017] This invention utilizes a vibratory feeder, a direct vibratory feeder, and a feeding plate with a U-shaped feeding channel and a picking-up section to systematically transport wire tail sheaths to an arc-shaped picking-up section. Simultaneously, a retractable limiting mechanism uses a limiting head to hold the wire tail sheaths within the feeding channel, achieving intermittent feeding to the picking-up section. This prevents wire tail sheaths from accumulating and congesting at the picking-up section and ensures accurate delivery of individual wire tail sheaths to the picking-up position, laying the foundation for stable subsequent picking-up. Furthermore, the design of the positioning device in conjunction with the picking-up section and the limiting mechanism involves the positioning device's mounting block being fitted around the picking-up section via its own mating groove. The mating groove and stop in the mounting block assist the detection element in accurately identifying whether the sheath is in place and prevent the wire tail sheath from shifting during transport. After the detection confirms the wire tail sheath is in place, the mounting block rises to avoid it, ensuring that the sheath's posture and position meet the requirements before picking-up, significantly improving the accuracy of subsequent picking-up and fitting, and avoiding feeding failures due to sheath shifting.

[0018] This utility model, through the linkage of the positioning device and the material picking device, and the cooperation of the rotary cylinder and the cylinder gripper of the material picking device, after the positioning device confirms that the sheath is in place and rises, the cylinder gripper of the material picking device rises to pick up the sheath, and then the rotary cylinder drives the gripper to rotate 90 degrees to send the sheath to the preset placement position. The whole process does not require manual intervention, which not only replaces the tedious operation of manual grabbing, positioning and transfer, but also ensures that the feeding rhythm is stable and controllable. It can match the continuous operation requirements of large-scale production of fiber optic patch cords and improve the overall production efficiency.

[0019] The core components of this utility model are all mature and universal accessories. The overall structure of the equipment is simple and the manufacturing cost is low. Through the design of the position, movement relationship and mutual linkage relationship between the components, the device can operate automatically without the need for special personnel to operate. It is only necessary to replenish the raw material of the wire tail sheath to the vibratory feeder periodically. Compared with manual feeding, it greatly reduces the input of manpower, reduces the overall production cost from both equipment production and daily operation, and improves the economic efficiency of production. At the same time, the equipment has a compact structure and saves space. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0039] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0042] In one embodiment of this utility model, such as Figure 1 , 2 As shown, an automatic feeding device for thread tail sheaths is provided, including a feeding device 10, a limiting mechanism 15, a positioning device 20, a picking device 30, and a frame. The frame supports the feeding device 10, the positioning device 20, and the picking device 30. The feeding device 10 conveys the thread tail sheaths in a specific direction to below the limiting mechanism 15. The limiting mechanism 15 uses telescopic movement to abut and release the thread tail sheaths, thereby pausing or continuing the conveying of the thread tail sheaths. The positioning device 20 is provided on one side of the limiting mechanism 15 along the discharge direction of the feeding device 10. The picking device 30 is provided below the positioning device 20. The picking device 30 clamps the positioned thread tail sheaths, adjusts their posture, and moves them to a preset fitting position. The feeding device 10, the limiting mechanism 15, the positioning device 20, and the picking device 30 work together to achieve automated feeding of thread tail sheaths.

[0043] like Figure 1-4 As shown, the feeding device 10 includes a vibratory feeder 11, a support frame 12, a linear vibratory feeder 13, a feeding plate 14, and a limiting mechanism 15. The vibratory feeder 11 is a commonly used feeding device in the prior art. The vibratory feeder 11 can generate high-frequency small-amplitude vibrations. By adjusting the vibration frequency and amplitude, the vibratory feeder 11 drives the tail sheath to gradually rise along the spiral track. The vibratory feeder 11 is fixed by the support frame 12. The height of the support frame 12 can be adjusted according to the installation height of the feeding plate 14 to ensure that the discharge end of the vibratory feeder 11 and the feeding plate 14 are at the same horizontal level, avoiding the tail sheath from getting stuck due to a height difference at the conveying connection. The outlet direction of the discharge end of the vibratory feeder 11 is aligned with one end of the feeding plate 14 to ensure that the tail sheath fed from the vibratory feeder 11 can accurately enter the feeding plate 14. The high-frequency vibration of the vibratory feeder 11 causes the disorderly stacked wire tail sheaths inside the vibratory feeder 11 to be arranged in an orderly manner along the spiral track, realizing the uniformity of the direction of the wire tail sheaths and individual conveying, avoiding channel blockage caused by disorderly stacking of the wire tail sheaths in the subsequent conveying process, and laying the foundation for subsequent accurate feeding.

[0044] The linear vibratory feeder 13 is a conventional linear vibratory feeding structure in the prior art. The linear vibratory feeder 13 is fixed above the frame, and the top surface of the linear vibratory feeder 13 is connected to the bottom surface of the feeding plate 14. The direction of the linear vibratory feeder 13 is consistent with the length direction of the feeding plate 14 and covers the entire length of the feeding plate 14. When the linear vibratory feeder 13 is working, it generates linear vibration along the length direction of the feeding plate 14, which drives the feeding plate 14 to vibrate synchronously, thereby driving the wire tail sheath on the feeding plate 14 to move towards the limiting mechanism 15 in a preset direction, providing driving force for the directional conveying of the wire tail sheath.

[0045] One end of the feeding plate 14 is connected to the discharge end of the vibratory feeder 11, and the other end extends below the limiting mechanism 15. A feeding channel 141 extending along its length is provided in the middle of the top surface of the feeding plate 14. A material-taking part 142 is provided at the end of the feeding plate 14 away from the vibratory feeder 11. The feeding channel 141 is a U-shaped groove. The groove width is greater than the maximum diameter of the wire tail sheath to ensure that the wire tail sheath can pass smoothly without lateral displacement. The groove depth is more than twice the maximum diameter of the wire tail sheath to avoid... The tail sheath is dislodged from the groove during the vibration conveying process; one end of the feeding channel 141 is connected to the feeding track at the discharge end of the vibratory plate 11, and the other end is connected to the picking part 142, forming a complete conveying path for the tail sheath from the vibratory plate 11 to the picking part 142. After the tail sheath enters the feeding channel 141 from the vibratory plate 11, it moves along the U-shaped groove under the vibration drive of the direct vibration feeder 13. The U-shaped structure restricts the lateral movement of the tail sheath, ensuring that the sheath is always conveyed in the preset direction.

[0046] The material-taking section 142 is an extension of the end of the feeding plate 14. The material-taking section 142 extends along the length of the feeding plate 14 and is located in the middle of the side of the feeding plate 14. The width of the material-taking section 142 is less than the maximum diameter of the wire tail sheath, while ensuring that the sheath will not slip off from either side when placed on the material-taking section 142. In this embodiment, the width of the material-taking section 142 is three-fifths of the maximum diameter of the wire tail sheath. The side of the material-taking section 142 adjacent to the limiting mechanism 15 is the material-taking section. The top surface of 142 is an arc-shaped surface that extends along the U-shaped structure of the feeding channel 141, which can guide and limit the sheath. The length of the picking part 142 is adapted to the length of a single wire tail sheath, and can only accommodate one wire tail sheath to stay, avoiding multiple sheaths from piling up at the same time. After the wire tail sheath moves from the feeding channel 141 to the picking part 142, it stops precisely on the picking part 142 under the restriction of the arc-shaped surface guide and positioning device 20, providing a stable working position for subsequent limiting, detection and picking.

[0047] The limiting mechanism 15 is located above the end of the feeding plate 14 adjacent to the material taking part 142, and is correspondingly arranged with respect to the feeding channel 141. The limiting mechanism 15 is a cylinder, and includes a limiting head 151 that can extend and retract relative to the feeding channel 141. The limiting head 151 is connected to the output shaft of the cylinder to realize the extension and retraction movement. The side of the limiting head 151 adjacent to the feeding channel 141, that is, the bottom surface of the limiting head 151, is provided with a protrusion that can extend into the feeding channel 141, and the bottom surface of the protrusion is provided with a groove that matches the wire tail sheath. The central axis of the groove is in the same vertical plane as the central axis of the feeding channel 141, ensuring that the protrusion can accurately extend into or out of the feeding channel 141 when the limiting head 151 extends and retracts. The limiting head 151 is withdrawn from the feeding channel to achieve contact or release between the limiting head 151 and the tail sheath. When there is already a tail sheath on the picking section 142, the limiting mechanism 15 drives the limiting head 151 to extend towards the feeding channel 141, enter the feeding channel 141 and contact the tail sheath to be conveyed later, preventing the sheath from continuing to move towards the picking section 142 and avoiding accumulation in the picking section 142. After the sheath in the picking section 142 has been picked up, the limiting mechanism 15 drives the limiting head 151 to retract away from the feeding channel 141, releasing the subsequent sheath to move along the feeding channel 141 to the picking section 142, realizing intermittent conveying of the tail sheath, ensuring that a single sheath enters the picking section 142 in sequence, and improving the accuracy of subsequent positioning and picking.

[0048] like Figure 5 , 6 As shown, the positioning device 20 is located on the side of the limiting mechanism 15 away from the vibratory plate 11 and above the material taking part 142. The positioning device 20 includes a telescopic mechanism 21, a mounting block 22, a slide rail 23, a slider 24, and a detection device 25. The telescopic mechanism 21 is a linear drive assembly. In this embodiment, a cylinder is selected. The telescopic mechanism 21 is fixed on the frame and is vertically located above the material taking part 142. The piston rod end of the telescopic mechanism 21 is fixedly connected to the top of the mounting block 22. The telescopic direction of the telescopic mechanism 21 is perpendicular to the top surface of the feeding plate 14.

[0049] The mounting block 22 is a rectangular block structure. The top of the mounting block 22 is fixedly connected to the piston rod of the telescopic mechanism 21. A mating groove 221 is provided on the side of the mounting block 22 adjacent to the material-taking part 142 and on the bottom surface of the mounting block 22. The mating groove 221 is located directly above the material-taking part 142, and its vertical projection overlaps with the projection of the material-taking part 142. The mating groove 221 is a U-shaped groove with its opening facing the material-taking part 142. The groove width is greater than the width of the material-taking part 142 to ensure that the material-taking part 142 can be smoothly embedded into the mating groove 221. The height of the mating groove 221 is greater than the distance between the material-taking part 142 and the end sleeve. The sum of the large diameters ensures that the material taking part 142 and the wire tail sheath can be completely embedded in the groove and that the wire tail sheath will not be squeezed or deformed. The mating groove 221 is opened along the length direction of the material taking part 142, and the center line of the mating groove 221 and the center line of the material taking part 142 are in the same vertical plane. When the telescopic mechanism 21 drives the mounting block 22 to descend, the mating groove 221 can accurately align with the material taking part 142 and be fitted onto the material taking part 142. The mating groove 221 limits the lateral displacement of the wire tail sheath placed on the material taking part 142 by limiting the material taking part 142 through the groove wall, thereby ensuring that the position of the sheath is stable during the testing process.

[0050] The end of the mating groove 221 away from the feeding plate 14 is provided with a stop block 222. The stop block 222 is a rectangular protrusion. When the mounting block 22 is sleeved on the picking part 142, the stop block 222 is in contact with the end face of the wire tail sheath away from the feeding channel 141 or leaves a small gap. The stop block 222 restricts the axial displacement of the sheath and ensures that the axial position of the sheath on the picking part 142 is maintained.

[0051] The slide rail 23 is a linear guide rail, which is set on the frame behind the mounting block 22. The length direction of the slide rail 23 is consistent with the extension direction of the telescopic mechanism 21. The slider 24 is slidably engaged with the slide rail 23. One end of the slider 24 is fixedly connected to the back of the mounting block 22, and the other end can slide freely along the slide rail 23. When the telescopic mechanism 21 drives the mounting block 22 to move vertically, the slider 24 slides synchronously along the slide rail 23. The guide and restriction of the slider 24 by the slide rail 23 prevents the mounting block 22 from tilting or deviating when it moves, and ensures that the mating groove 221 can accurately fit the material picking part 142.

[0052] The telescopic mechanism 21 is connected to the control unit of the detection device 25 and the material handling device 30. When the limit mechanism 15 completes the release action and reports that the material handling part 142 has delivered the wire tail sheath, after the detection device 25 completes the detection and reports that it is qualified, the control unit drives the telescopic mechanism 21 to retract, thereby driving the mounting block 22 to rise to the clearance position to avoid interfering with the material handling action of the material handling device 30.

[0053] The detection device 25 is a non-contact detection sensor, fixed to the top surface of the mounting block 22, with the detection direction facing the wire tail sheath on the material handling section 142, and the detection point aligned with the preset detection position of the wire tail sheath. When the mounting block 22 descends into the material handling section 142, the detection device 25 sends a detection signal to the material handling section 142. If there is a wire tail sheath on the material handling section 142 and it is in the correct position, the signal is reflected or blocked by the sheath, and the detection device 25 outputs a qualified signal to the control unit, triggering the subsequent material handling action. If there is no sheath on the material handling section 142 or the sheath is misaligned, the detection device 25 outputs an unqualified signal, and the control unit drives the limit mechanism 15 to release a new sheath, ensuring that the sheath is accurately positioned before material handling.

[0054] like Figure 7 , 8 As shown, the material handling device 30 is located below the positioning device 20, and the material handling end of the material handling device 30 is correspondingly arranged with the material handling part 142. The material handling device 30 includes a drive mechanism 31, an auxiliary mechanism 32, a mounting plate 33, a rotary cylinder 34, and a cylinder gripper 35. The drive mechanism 31 is a linear drive assembly. In this embodiment, a cylinder is selected. The drive mechanism 31 is horizontally fixed on the bottom support of the frame. The extension and retraction direction of the extension shaft of the drive mechanism 31 is parallel to the length direction of the feeding plate 14.

[0055] The auxiliary mechanism 32 includes a slider and a guide rail. The guide rail is arranged parallel to the telescopic shaft of the drive mechanism 31 and is fixed to the side of the frame. The slider is fixedly connected to the mounting plate 33 and slidably connected to the guide rail. The top surface of the mounting plate 33 is provided with a connecting plate 331. The connecting plate 331 is an L-shaped metal plate. One side of the plate is fixed to the top surface of the mounting plate 33, and the other side is fixed to the telescopic shaft of the drive mechanism 31. When the drive mechanism 31 drives the mounting plate 33 to slide, the slider slides relative to the guide rail, which helps support the mounting plate 33 and prevents the mounting plate 33 from tilting due to unilateral force, thus ensuring that the mounting plate 33 moves smoothly.

[0056] The rotary cylinder 34 is fixed to the side of the mounting plate 33 away from the slider. The rotary cylinder 34 can slide relative to the feeding plate 14 as the mounting plate 33 slides. The rotary cylinder 34 is located below the side of the picking part 142 away from the positioning device 20 and is fixed to the mounting plate 33. The output end of the rotary cylinder 34 is provided with a rotary arm 341. The rotary arm 341 is a long strip structure, one end of which is fixed to the rotation axis of the rotary cylinder 34, and the other end is located directly below the picking part 142 and is fixedly connected to the cylinder gripper 35. The rotary cylinder 34 can drive the rotary arm 341 to rotate relative to the picking part 142. In the initial state, the rotary arm 341 extends horizontally to below the picking part 142 and drives... The telescopic shaft of mechanism 31 extends, causing the mounting plate 33 to drive the rotary cylinder 34 to make the rotary arm 341 protrude from the end of the picking part 142 away from the feeding plate 14. At this time, the cylinder gripper 35 is in the open state, and the gripping part of the cylinder gripper 35 is on the same horizontal plane as the wire tail sheath. The telescopic shaft of the drive mechanism 31 retracts, causing the cylinder gripper 35 to move to both sides of the wire tail sheath. After the cylinder gripper 35 closes to grip the wire tail sheath, the telescopic shaft of the drive mechanism 31 extends, causing the cylinder gripper 35 to drive the wire tail sheath away from the picking part 142. Subsequently, the rotary cylinder 34 drives the rotary arm 341 to rotate 90°, adjusting the wire tail sheath to a sleeve posture that is compatible with the optical fiber clamping device.

[0057] The cylinder gripper 35 is a parallel opening and closing pneumatic gripper, fixed to the end of the rotating arm 341. Symmetrical gripping holes 351 are provided on the inner sides of its two gripper arms. Each gripping hole 351 is a semi-circular groove with a radius matching the maximum diameter of the wire tail sheath, ensuring it can abut against the outer wall of the wire tail sheath during gripping and preventing excessive deformation of the sheath. Below the gripping holes 351 is a clearance groove, a rectangular hole. The sum of the widths of the two clearance grooves is greater than the width of the material handling section 142, ensuring that the material handling section 142 can pass through the clearance groove when the cylinder gripper 35 grips the sheath, preventing interference between the cylinder gripper 35 and the material handling section 142. The end of the gripping hole 351 furthest from the material handling section 142... An auxiliary hole 352 is provided, which is connected to the clamping hole 351. The diameter of the auxiliary hole 352 gradually increases along the clamping hole 351. The auxiliary hole 352 serves to assist the optical fiber in entering the tail sheath. When the cylinder gripper 35 is in the open state, the mounting plate 33 drives the cylinder gripper 35 to move towards the picking part 142, so that the picking part 142 is located in the cylinder gripper 35. Then the cylinder gripper 35 closes and clamps the tail sheath on the picking part 142 through the clamping hole 351. After clamping, it is moved with the drive mechanism 31, and then rotated with the rotating arm 341 to the sleeve position. Finally, the tail sheath is opened and released to complete the picking action.

[0058] The working principle of this utility model is as follows: An automatic feeding device for thread tail sheaths first involves the operator feeding thread tail sheaths into the vibratory feeder 11. The vibratory feeder 11 is then activated, and the vibration drives the thread tail sheaths (such as...) to... Figure 9As shown, the material rises and is conveyed in an orderly manner to the feeding channel 141 of the feeding plate 14; the direct vibration feeder 13 starts, causing the feeding plate 14 to vibrate, driving the sheath in the feeding channel 141 to move towards the picking part 142. At this time, the limiting head 151 of the limiting mechanism 15 retracts, allowing the sheath to enter the picking part 142; the telescopic mechanism 21 of the positioning device 20 extends, driving the mounting block 22 to descend, so that the mating groove 221 is fitted around the picking part 142, and the stop block 222 and the end of the wire tail sheath correspond to form a bidirectional limit;

[0059] The detection device 25 starts the detection. When the first wire tail sheath moves to the material handling section 142 and stops, if the wire tail sheath is in place and qualified, the detection device 25 sends a signal to the control unit. The limit head 151 extends to block subsequent sheaths from entering, preventing accumulation in the material handling section 142. The telescopic mechanism 21 drives the mounting block 22 to rise and reset. Then, the cylinder gripper 35 opens, and the drive mechanism 31 of the material handling device 30 drives the mounting plate 33 and the rotary cylinder 34 to move the cylinder gripper 35 to both sides of the material handling section 142, so that the material handling section 142 is located between the grippers. Subsequently, the cylinder gripper... The device closes at 35, gripping the wire tail sheath through the gripping hole 351. After gripping, the drive mechanism 31 drives the mounting plate 33 to move the cylinder gripper 35 away from the material handling section 142. Then, the rotary cylinder 34 drives the rotary arm 341 to rotate 90°, adjusting the wire tail sheath to the fitting position. The cylinder gripper 35 opens to release the sheath, cooperating with the fiber optic clamping device to complete the fitting. Finally, the drive mechanism 31 drives the material handling device 30 to reset, the limit head 151 retracts, and the next sheath is released into the material handling section 142. The above steps are repeated to achieve continuous automated feeding. Through the above process, this equipment completely replaces manual operation, improves feeding efficiency and accuracy, reduces overall production costs, and meets the needs of large-scale production of fiber optic patch cords.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
