Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, and specifically to a tube insertion mechanism. Background Technology

[0002] In the cable manufacturing process, heat shrink tubing is commonly used as a protective material to ensure reliable protection of the joints. In practice, the tubing is fitted over the cable connection; after heat treatment, the tubing shrinks and tightly wraps around the joint, thus forming an effective insulation and protective layer.

[0003] Currently, this process mainly relies on manual operation: operators first cut the heat shrink tubing to the specified size, and then manually thread it onto the designated position on the cable. This traditional method is not only inefficient but also prone to errors, making it difficult to guarantee product qualification rates. Therefore, it is necessary to design a tubing threading mechanism to automate the process and reduce the manual steps involved in threading the tubing onto the wire. Utility Model Content

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0061] See Figures 1-7 A sleeve-feeding mechanism includes a frame 1, on which:

[0062] Pipe clamp assembly 2, which is used to clamp the sleeve 3;

[0063] Wire clamp assembly 4, which is used to clamp wire 5;

[0064] Feeding assembly 6, which is used to feed the sleeve 3 to the clamping station of the clamping assembly 2;

[0065] The cutting assembly 7 cuts the sleeve 3 after it is clamped by the pipe clamp assembly 2, so as to cut the sleeve 3 connected to the pipe clamp assembly 2 and the feeding assembly 6. The long part of the sleeve 3 stays on the feeding assembly 6, and the cut part of the sleeve 3 is on the pipe clamp assembly 2.

[0066] The movable component 8 is connected to the pipe clamp component 2 at its movable end and is cut by the cutter component 7. The sleeve 3 on the pipe clamp component 2 moves along the wire clamp component 4 through the movable component 8 to fit the sleeve 3 on the outside of the wire 5.

[0067] This sleeve-threading mechanism achieves fully automated operation of the sleeve-threading process through the coordinated cooperation of its components. The feeding component 6 automatically transports the sleeve 3 to the clamping station of the clamping component 2. After the clamping component 2 reliably clamps the sleeve 3, the cutting component 7 precisely cuts the sleeve 3, replacing the manual steps of picking up and placing the sleeve and cutting it, reducing manual intervention and avoiding dimensional errors that may occur during manual cutting. The moving component 8 drives the clamping component 2 to accurately fit the cut sleeve 3 onto the wire 5 fixed by the wire clamping component 4. The entire process requires no manual threading, significantly improving production efficiency and avoiding problems such as inaccurate sleeve fitting and product defects caused by uneven force and positioning deviations during manual operation, thus significantly improving the product qualification rate. Simultaneously, all components are integrated on the frame 1, forming an organic whole, ensuring the continuity and stability of the sleeve feeding, cutting, and fitting processes, providing reliable equipment support for the automation of sleeve threading in cable manufacturing.

[0068] The feeding assembly 6, cutting assembly 7, pipe clamp assembly 2, and wire clamp assembly 4 are arranged sequentially from top to bottom along the height of the frame 1. This top-to-bottom arrangement along the height of the frame 1 creates a vertical working path for the conveying, cutting, and fitting of the sleeve 3. The sleeve 3 is conveyed down from the upper feeding assembly 6. Before being cut by the cutting assembly 7, the sleeve 3 is clamped by the middle pipe clamp assembly 2. After the cutting assembly 7 cuts, the sleeve 3 will not fall off. Then, the moving assembly 8 drives the pipe clamp assembly 2 to move downwards, accurately fitting it onto the wire 5 fixed by the lower wire clamp assembly 4. The tight connection of each link reduces unnecessary path loss and improves work efficiency. At the same time, the vertical arrangement makes full use of the space of the frame 1, with the moving assembly 8 located inside the frame 1. This makes the overall equipment structure more compact and saves installation space.

[0069] The pipe clamp assembly 2 includes:

[0070] The gripper cylinder 9 is used to provide the clamping power for the sleeve 3.

[0071] The first gripper arm 10 is laterally and reciprocally mounted on the gripper cylinder 9.

[0072] The second gripper arm 11 is laterally and reciprocally mounted on the gripper cylinder 9.

[0073] Both the first gripper arm 10 and the second gripper arm 11 are provided with grippers 12, and each gripper 12 is provided with a gripper groove that is adapted to the outer hub of the sleeve 3.

[0074] The first gripper arm 10 and the second gripper arm 11 move laterally and reciprocate to switch the opening or clamping closure of the pipe clamp assembly 2.

[0075] Specifically: The pipe clamp assembly 2 uses an existing finger cylinder. The pipe clamp assembly 2 can be formed by simply fixing and installing a gripper arm on the movable end of the finger cylinder. The gripper 12 is fixed to the gripper arm by screws, or the gripper 12 is integrated with the gripper arm by metal processing.

[0076] The cutting blade assembly 7 includes:

[0077] Cutter cylinder 13, which provides power to cut the sleeve 3;

[0078] The first connecting arm 14 is laterally reciprocatingly mounted on the cutter cylinder 13;

[0079] The second connecting arm 15 is laterally reciprocatingly mounted on the cutter cylinder 13;

[0080] Both the first connecting arm 14 and the second connecting arm 15 are equipped with a cutter 16, which is used to cut when the first connecting arm 14 and the second connecting arm 15 are close to each other.

[0081] Specifically: the cutter cylinder 13 can also be an existing finger cylinder, which works on the same principle as the pipe clamp assembly 2, so it will not be described in detail here.

[0082] The feeding assembly 6 includes:

[0083] The first guide wheel 17 is rotatably mounted on the frame 1;

[0084] The second guide wheel 18 is rotatably mounted on the frame 1;

[0085] The first guide wheel 17 and the second guide wheel 18 act on the outer hub of the sleeve 3 during rotation to transport the sleeve 3, and a guide groove is formed between the first guide wheel 17 and the second guide wheel 18.

[0086] The frame 1 is equipped with a conveyor motor 19, and the first guide wheel 17 and / or the second guide wheel 18 are fixedly connected to the drive shaft of the conveyor motor 19.

[0087] The guide groove formed between the first guide wheel 17 and the second guide wheel 18 effectively limits the movement of the sleeve 3, ensuring that it moves along a predetermined path during transport and preventing deviation or swaying, thus guaranteeing the stability of the transport direction. The conveying motor 19 provides power for the rotation of the guide wheels. By controlling the speed and running time of the conveying motor 19, the transport length of the sleeve 3 can be precisely controlled (or by calculating the number of rotations of the motor shaft of the conveying motor 19), reducing errors in the transport length. Furthermore, the rolling contact between the guide wheels and the outer hub of the sleeve 3 reduces friction and damage to the outer surface of the sleeve 3, protecting its integrity and ensuring the smooth progress of subsequent processes, significantly improving the accuracy and efficiency of the sleeve 3 transport.

[0088] The rack 1 is also equipped with:

[0089] The traction component 20 is used to position the sleeve 3 in order to cooperate with the feeding component 6 to transport the sleeve 3.

[0090] The traction assembly 20 includes a first positioning member 22 located above the feeding assembly 6. The first positioning member 22 is provided with a positioning groove 23 for positioning the sleeve 3. The first positioning member 22 is open at both ends and the positioning groove 23 is connected to the guide groove.

[0091] The traction assembly 20 also includes a traction wheel 21 rotatably disposed above the first positioning member 22, and the traction wheel 21 is provided with a slot 24 for assisting the positioning sleeve 3;

[0092] The traction assembly 20 also includes a second positioning member 27 located at the lower part of the feeding assembly 6. The second positioning member 27 has a cavity that runs vertically through its interior to connect with the positioning groove 23. The second positioning member 27 is located above the cutter assembly 7. The sleeve 3 passes through the first positioning member 22, the guide groove and the second positioning member 27 in sequence.

[0093] The traction assembly 20 guides and constrains the conveying process of the sleeve 3 through a multi-positioning structure, significantly improving the stability of the sleeve 3 conveying. The positioning groove 23 of the first positioning member 22 is adapted to the sleeve 3 to position the upper part of the sleeve 3; the slot 24 of the traction wheel 21 further assists in positioning to prevent the sleeve 3 from shifting in the early stage of conveying; the cavity of the second positioning member 27 is connected to the positioning groove 23 to position the lower part of the sleeve 3, ensuring that the sleeve 3 maintains a stable posture before entering the guide groove of the feeding assembly 6 and after exiting the guide groove. This multi-level positioning design effectively avoids problems such as shaking and bending of the sleeve 3 due to its own weight or external interference during the conveying process, enabling the sleeve 3 to be accurately conveyed to the clamping position of the clamping assembly 2.

[0094] The rack 1 is also equipped with:

[0095] Detector 25, the detector 25 is used to detect whether the sleeve 3 passes through the first positioning member 22;

[0096] The outer side of the first positioning member 22 is provided with a detection avoidance hole 26 corresponding to the detection probe of the detector 25.

[0097] The detector 25 can monitor in real time whether the sleeve 3 has successfully passed through the first positioning member 22 and provide timely feedback on the conveying status of the sleeve 3. When the sleeve 3 fails to pass through the first positioning member 22 as expected, the detector 25 can send a signal to stop the equipment in time or issue an alarm, preventing the equipment from continuing to operate without the sleeve 3 being conveyed, reducing ineffective operations and equipment idling, and lowering the risk of energy waste and equipment damage. The detection clearance hole 26 on the first positioning member 22 provides a detection channel for the detection probe of the detector 25, ensuring that the detector 25 can accurately and unobstructedly detect the presence or absence of the sleeve 3, thus guaranteeing the accuracy of the detection.

[0098] The frame 1 is equipped with:

[0099] The travel detection switch 28 is used to detect the position of the movable end of the moving component 8 during the lifting and lowering process.

[0100] The number of travel detection switches 28 is provided, and the travel detection switches 28 are arranged vertically at intervals along the lifting height direction of the moving component 8.

[0101] The travel detection switch 28 can monitor the position of the moving end of the moving component 8 in real time, providing a basis for precise control of the lifting action. Several travel detection switches 28, arranged at intervals along the lifting height direction, can cover the entire movement stroke of the moving component 8, accurately detecting key positions of the pipe clamp component 2 during the rising or falling process, such as the initial position, the position where the sleeve 3 is about to be fitted onto the wire 5, and the position after fitting. Through this positional information, the start and stop of the moving component 8 can be precisely controlled, ensuring that the pipe clamp component 2 can accurately reach the fitting position with the sleeve 3, avoiding damage to the sleeve 3 from collision with the wire 5 due to excessive lifting or insufficient lifting, thus effectively improving the control precision of the lifting action and ensuring the accuracy and reliability of the sleeve 3 fitting process.

[0102] The mobile component 8 includes:

[0103] The lifting motor 29 has its output end connected to the pipe clamp assembly 2 and provides lifting power.

[0104] Lead screw 30, which is connected to the motor shaft of lifting motor 29;

[0105] Nut sleeve 31 is sleeved on the outside of lead screw 30 and fixedly connected to pipe clamp assembly 2. Nut sleeve 31 and lead screw 30 are threadedly connected to each other. The output end of lifting motor 29 is connected to pipe clamp assembly 2 through lead screw 30 and nut sleeve 31.

[0106] A linear sliding assembly is provided between the frame 1 and the nut sleeve 31 to constrain the linear movement of the nut sleeve 31 during the rotation of the lead screw 30;

[0107] The linear sliding assembly includes a linear guide rail 33 fixed on the frame 1 and a slider 34 that slides with the linear guide rail 33.

[0108] The nut sleeve 31 is provided with a connecting piece 32 that is fixedly connected to the slider 34.

[0109] The lifting motor 29, through the threaded transmission between the lead screw 30 and the nut sleeve 31, converts the motor's rotational motion into the linear lifting motion of the nut sleeve 31. This transmission method features high precision and smooth operation, accurately controlling the lifting speed and displacement of the pipe clamp assembly 2, ensuring that the sleeve 3 can be fitted onto the wire 5 at the appropriate speed and position. The linear sliding assembly, including the linear guide rail 33 and the slider 34, guides and constrains the movement of the nut sleeve 31, preventing it from rotating or shifting during lifting, thus ensuring the linearity and stability of the lifting motion of the pipe clamp assembly 2. Furthermore, the lead screw and nut transmission structure has strong load-bearing capacity, stably supporting the weight of the pipe clamp assembly 2 and the sleeve 3, ensuring no jamming or shaking occurs during lifting, further improving the operational reliability and control precision of the moving assembly 8, and providing strong support for the precise fitting of the sleeve 3.

[0110] In this technical solution, the frame 1 is provided with a vertically arranged support plate 39, the support plate 39 is provided with a lead screw rotating seat 40, there are two lead screw rotating seats 40, the two lead screw rotating seats 40 are fixedly arranged on the support plate 39 at an upper and lower interval, and the nut sleeve 31 is located between the two lead screw rotating seats 40.

[0111] The nut sleeve 31 is equipped with a detection element 41 that cooperates with the travel detection switch 28.

[0112] The top of the support plate 39 is provided with a fixing plate 42. The lifting motor 29 is fixed on the top of the fixing plate 42, and the drive shaft of the lifting motor 29 passes through the fixing plate 42 and is connected to the lead screw 30 through a coupling.

[0113] A conveyor motor 19 is provided on the top of the fixed plate 42. A first fixed seat is provided on one side of the conveyor motor 19 and fixed on the top of the fixed plate 42. The drive shaft of the conveyor motor 19 passes through the first fixed seat and is connected to the first guide wheel 17. A second fixed seat is also provided on the top of the fixed plate 42. The second guide wheel 18 is rotatably mounted on the second fixed seat. The cutter cylinder 13 is fixedly mounted on the bottom of the fixed plate 42.

[0114] The travel detection switch 28 is fixedly mounted on the side of the support plate 39.

[0115] One end of the fixing plate 42 is provided with a back plate 43 fixed behind the support plate 39. The bottom of the back plate 43 is provided with a base plate 44 for fixing the lowest lead screw rotating seat 40. The side of the base plate 44 is provided with a connecting plate 45. One end of the connecting plate 45 extends upward and is fixedly connected to the clamping cylinder 35 of the wire clamp assembly 4.

[0116] A cylinder lifting clearance groove 46 is provided between the base plate 44 and the connecting plate 45 to avoid the gripper cylinder 9 that follows the downward movement of the moving component 8.

[0117] The linear guide rail 33 is fixedly mounted on the rear side of the support plate 39. The connector 32 is L-shaped, with the long arm of the connector 32 fixedly connected to the nut sleeve 31 and the short arm of the connector 32 fixedly connected to the slider 34.

[0118] The wire clamp assembly 4 includes:

[0119] Clamping cylinder 35, the clamping cylinder 35 is used to provide power for clamping wire 5;

[0120] The first clamping arm 36 is oscillatingly mounted on the clamping cylinder 35;

[0121] The second clamping arm 37 is oscillatingly mounted on the clamping cylinder 35;

[0122] Both the first clamping arm 36 and the second clamping arm 37 are provided with clamping claws 38, and each clamping claw 38 is provided with a groove that is adapted to the outer surface of the wire 5; the first clamping arm 36 and the second clamping arm 37 are brought together or moved apart by swinging to switch the opening or clamping closure of the wire clamp assembly 4.

[0123] Specifically, the wire clamp assembly 4 can be a Y-shaped finger cylinder, the principle of which is the same as that of the pipe clamp assembly 2, so it will not be described in detail here.

[0124] The clamping cylinder 35 provides stable clamping power to the wire clamp assembly 4. By controlling the movement of the clamping cylinder 35, the first clamping arm 36 and the second clamping arm 37 can swing flexibly, opening or closing the wire clamp assembly 4, facilitating the placement and fixing of the wire 5. The grooves on the clamping claws 38 that are adapted to the outer surface of the wire 5 can fit tightly with the wire 5, forming a reliable clamping and positioning of the wire 5, preventing the wire 5 from moving, rotating, or shaking during the sleeve 3 installation process, and ensuring that the wire 5 is always in the predetermined installation position. This stable clamping provides a solid foundation for the installation of the sleeve 3, enabling the clamp assembly 2 to accurately install the sleeve 3 onto the wire 5, avoiding installation deviations caused by wire 5 displacement, effectively improving the stability of wire 5 clamping and the accuracy of sleeve 3 installation, and ensuring the consistency of product quality.

[0125] The specific workflow is as follows:

[0126] 1. The sleeve 3 is conveyed into place by the conveyor motor 19;

[0127] 2. The pipe clamp assembly 2 clamps the sleeve 3 that extends out of the second positioning member 27;

[0128] 3. The cutter assembly 7 cuts off the sleeve 3, and the cutter assembly 7 resets;

[0129] 4. The lifting motor 29 starts, driving the pipe clamp assembly 2 to descend. The sleeve 3 is fitted onto the wire 5 held by the wire clamp assembly 4. There are three stroke detection switches 28. When the lifting motor 29 descends to the middle position (the middle stroke detection switch 28 detects the nut sleeve 31), the wire clamp assembly 4 opens. The lifting motor 29 continues to drive the pipe clamp assembly 2 to descend, so that the sleeve 3 is inserted into the designated position of the wire 5 (the root of the wire 5, which can be understood as the maximum descending stroke position of the lifting motor 29 in the process).

[0130] 5. After the sleeve is inserted, the pipe clamp assembly 2 resets and releases the sleeve, and the lifting motor 29 rises, driving the pipe clamp assembly 2 to reset to its initial position.

[0131] In this technical solution, in order to achieve auxiliary fixing of the wire 5, an auxiliary clamping mechanism 47 is provided on the outer side of the branch of the wire 5. The structure of the auxiliary clamping mechanism 47 is the same as that of the wire clamp assembly 4, and will not be described in detail here.

[0132] The wire 5 includes a vertical section and a horizontal section. The clamping mechanism 47 clamps the horizontal section of the wire 5, and the vertical section of the wire 5 is used to install the sleeve 3.

[0133] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
