Description

Technical Field

[0001] This utility model relates to the technical field of wire processing, and in particular to a heat shrink tubing device. Background Technology

[0002] The heat shrink tubing application device achieves precise application of heat shrink tubing to various wires (such as wires, cables, electronic connecting wires, etc.) through automated or semi-automated operation, ultimately achieving functions such as protection, insulation, or marking of the wires.

[0003] In some related technologies, patent CN113346314A discloses an automatic wire cutting and terminal crimping device, including a heat shrink tubing mounting mechanism disposed at one end of a wiring moving mechanism, and a wire taking mechanism disposed between the wiring moving mechanism and the heat shrink tubing mounting mechanism. The wire taking mechanism moves the wire on the wiring moving mechanism to the heat shrink tubing mounting mechanism. Two heat shrink tubing transmission devices in the heat shrink tubing mounting mechanism transmit heat shrink tubing and cut the heat shrink tubing into segments. The first heat shrink tubing gripper and the shifting sliding device in the heat shrink tubing clamping unit are respectively disposed on one side of the two heat shrink tubing transmission devices. The first heat shrink tubing gripper and the second heat shrink tubing gripper in the shifting sliding device are both used to grip the heat shrink tubing transmitted by the heat shrink tubing transmission devices. The shifting sliding device moves the second heat shrink tubing gripper to one end of the wire and moves the wire toward the side of the first heat shrink tubing gripper, so that the other end of the wire is fitted with heat shrink tubing.

[0004] The above solution has some technical problems. For example, if the second heat shrink tubing clamp is moved by the sliding device, and one end of the wire is held by the second heat shrink tubing clamp, and the wire is moved to the side of the first heat shrink tubing clamp to fit the other end of the wire with heat shrink tubing, if the wire end is tilted, the heat shrink tubing cannot be accurately fitted to the outside of the wire end. Moreover, this solution is generally used to fit a single wire with heat shrink tubing, and it is difficult to accurately fit two wires that are bonded together with heat shrink tubing.

[0042] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0043] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0044] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or indirectly on that other component.

[0045] When a component is said to be "connected to" another component, it can be directly connected to the other component or indirectly connected to that other component.

[0046] 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 accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] 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 technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0048] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0049] The following describes in detail the specific structure of a heat shrink tubing device provided by an embodiment of this utility model, according to the appendix. Figure 1-9 As shown, the specific structure of this heat shrink tubing device includes a workbench 1, a positioning mechanism 2, a wire pushing mechanism 3, and a heat shrink tubing assembly mechanism 4.

[0050] The workbench 1 is the basic support structure of the entire heat shrink tubing device. It provides a platform for the installation and support of the positioning mechanism 2, the wire pushing mechanism 3, and the heat shrink tubing assembly mechanism 4. That is, all the operating parts are installed on the top of the workbench 1, which can withstand the weight of the above-mentioned mechanisms and the pressure generated by each mechanism during operation, thus ensuring the stability of each mechanism during operation.

[0051] according to Figure 4 The positioning mechanism 2 includes a first support frame 21, a positioning seat 22, and a separation component 23. The first support frame 21 is disposed on the top of the workbench 1. The positioning seat 22 is disposed on the first support frame 21 and has a positioning cavity 222. The separation component 23 includes a first driving member and a separation blade. The first driving member is disposed on the first support frame 21 and its power output shaft is connected to the separation blade. The separation blade is located directly above the positioning cavity 222.

[0052] Specifically, the first support frame 21, as the main support structure of the positioning mechanism 2, is installed on the top of the workbench 1 to fix the positioning seat 22 and the separation component 23, so as to bear the weight of the positioning seat 22 and the separation component 23 and the force generated during operation. The positioning seat 22 is used to fix the end of the wire and provide a precise positioning space; the positioning seat 22 has a through positioning cavity 222, the shape and size of which are designed according to the outer diameter of the wire to ensure that the wire can be accurately inserted and fixed in it. The positioning seat 22 is installed on the first support frame 21, and the opening direction of the positioning cavity 222 is consistent with the pushing direction of the wire pushing mechanism 3, so that the ends of each wire can be pushed into the positioning cavity 222. The first driving member provides power to the separating blade, driving the separating blade to move up and down. The separating blade is used to separate the ends of two wires that are stuck together and fix the ends of the wires. Since the separating blade is located directly above the positioning cavity 222, when the first driving member is activated, the separating blade can accurately descend into the positioning cavity 222.

[0053] During operation, the wire pushing mechanism 3 pushes the ends of two mutually bonded wires to the entrance of the positioning cavity 222. After the ends of each wire enter the positioning cavity 222, the cavity wall of the positioning cavity 222 restricts the movement of the wires, keeping them in a fixed position. The positioning cavity 222 of the positioning seat 22 is designed to ensure that the ends of the wires can be accurately inserted and fixed therein, providing stable support for subsequent separation operations. When the first driving component is activated, it drives the separating blade to move downward, that is, the separating blade moves closer to the middle of the positioning cavity 222 until it can pass through the positioning cavity 222. When the separating blade is inserted between the ends of the two mutually bonded wires, the ends of the wires are separated by the blade. At the same time, during the descent of the separating blade, it pushes each wire, fixing the ends of each wire between the outer side of the separating blade and the cavity wall of the positioning cavity 222. In this way, the ends of the two wires are accurately separated and fixed (fixed between the outer side of the separating blade and the cavity wall of the positioning cavity 222), which is convenient for subsequent heat shrink tubing.

[0054] It should be noted that the shape and size of the separating blade in this embodiment of the utility model are designed according to the outer diameter of the wire and the bonding method. It is usually thin or blade-shaped and can be accurately inserted into the bonding joint between the ends of the wire.

[0055] It is understood that the first driving component in this embodiment of the present invention is a cylinder 242, and the power output shaft of the cylinder 242 is connected to the top of the separating blade.

[0056] according to Figure 2 As shown, the wire pushing mechanism 3 is movably mounted on the top of the workbench 1 and can move closer to or further away from the positioning cavity 222.

[0057] Specifically, the wire pushing mechanism 3 is mainly used to push the ends of two mutually bonded wires from their initial positions into the positioning cavity 222. This ensures that each wire accurately enters the subsequent heat shrink tubing application position. By accurately controlling the distance and speed at which the wire pushing mechanism 3 pushes each wire, it ensures that the ends of each wire are accurately inserted into the positioning cavity 222, avoiding insufficient or excessive pushing that could prevent the wires from being properly secured. Furthermore, the wire pushing mechanism 3 can be positioned closer to or further away from the positioning cavity 222; this flexibility allows the pushing mechanism to adjust its position according to actual needs to accommodate wires of different lengths.

[0058] according to Figure 1 and Figure 4 As shown, the heat shrink tubing assembly mechanism 4 includes a heat shrink tubing feeding assembly 41, a cutting assembly 42, and a heat shrink tubing clamping assembly 43. The heat shrink tubing feeding assembly 41 is located next to the worktable, the heat shrink tubing clamping assembly 43 is set on the worktable 1 and can move along the direction of the positioning seat 22, and the cutting assembly 42 is located between the heat shrink tubing feeding assembly 41 and the heat shrink tubing clamping assembly 43.

[0059] Specifically, the heat shrink tubing feeding assembly 41 is responsible for conveying the heat shrink tubing from the storage location to between the cutting assembly 42 and the heat shrink tubing clamping assembly 43. Located next to the workbench 1, it facilitates continuous supply of heat shrink tubing. The cutting assembly 42 cuts the heat shrink tubing to the appropriate length, ensuring accurate placement of the heat shrink tubing on the wire end. The heat shrink tubing clamping assembly 43 clamps the end of the heat shrink tubing and stretches it close to the wire end to complete the placement. Because the heat shrink tubing clamping assembly 43 can move closer to or further away from the positioning seat 22, it ensures accurate placement of the heat shrink tubing on the wire end.

[0060] During operation, the heat shrink tubing is fed from the reel of the heat shrink tubing feeding assembly 41 and conveyed to the position between the cutting assembly 42 and the heat shrink tubing clamping assembly 43. Once the heat shrink tubing is conveyed to the designated position, the heat shrink tubing clamping assembly 43 is activated, clamping the end of the heat shrink tubing. Simultaneously, the heat shrink tubing clamping assembly 43 moves along the direction of the positioning seat 22 until the heat shrink tubing is stretched near the end of the wire. The clamping device then continues to hold the end of the heat shrink tubing, ensuring that the opening of the heat shrink tubing is aligned with the end of the wire. As the heat shrink tubing clamping assembly 43 continues to move, it places the end of the heat shrink tubing over the outside of the end of the wire. Once the heat shrink tubing is accurately placed over the end of the wire, the cutting assembly 42 is activated, cutting off any excess heat shrink tubing to ensure that the cut heat shrink tubing is of appropriate length, neither too long nor too short. Thus, through the coordinated work of the heat shrink tubing feeding assembly 41, the clamping assembly, and the cutting assembly 42, a series of operations such as feeding, clamping, stretching, and cutting of the heat shrink tubing are realized. The overall operation process can be automated, ensuring that the heat shrink tubing can be accurately fitted onto the end of the wire. Furthermore, by precisely controlling the operation of each component, the assembly efficiency of fitting the heat shrink tubing is improved.

[0061] It should be noted that the heat shrink tubing device in this solution only needs to be fitted with heat shrink tubing on one end of the wire; the other end of the wire does not need to be fitted with heat shrink tubing.

[0062] according to Figure 4 As shown, in some specific embodiments, the positioning seat 22 includes a second driving member 24, a third driving member 25, a slide rail 241, and two seat bodies 221; the slide rail 241 is disposed on the first support frame 21, and the seat bodies 221 are all movably disposed on the slide rail 241; a positioning cavity 222 is provided on the opposite side of the two seat bodies 221; the second driving member 24 is disposed on the first support frame 21 and is drivenly connected to each seat body 221, and can drive each seat body 221 away from each other; the third driving member 25 is disposed on the slide rail 241 and is drivenly connected to each seat body 221, and can drive each seat body 221 closer to each other.

[0063] Specifically, the slide rail 241 provides a moving path for the seat 221, ensuring that each seat 221 can move smoothly in a predetermined direction. The slide rail 241 is a linear guide rail, capable of withstanding the force generated when each seat 221 moves. The seat 221 is used to fix the end of the wire, providing positioning and support. The positioning cavity 222 is located between the two seats. The second drive member 24 drives the two seats 221 away from each other to insert or remove the wire. The third drive member 25 is used to drive the two seats 221 closer together, fixing the end of the wire in the positioning cavity 222, and cooperating with the separating blade to achieve the positioning function of the end of each wire.

[0064] In the initial state, the second drive member 24 drives the two seats 221 to be far apart, ensuring that the distance between the two positioning seats 22 is sufficient to insert the end of the wire, so that the wire pushing mechanism 3 can push the end of the wire into the positioning cavity 222 of the positioning seat 22. Then, the second drive member 24 cancels the driving force applied to the two seats 221, and at the same time, the third drive member 25 is activated to drive the two seats 221 to move closer to each other along the slide rail 241. As the positioning cavity 222 of the seat 221 gradually approaches the end of the wire, when the two seats 221 are completely close, the end of the wire is fixed in the positioning cavity 222, and the wire is fixed by the inner wall of the positioning cavity 222. The outer diameters of the wires are tightly fitted to ensure that the wires will not move during subsequent operations. Then, the first drive of the separation component 23 is activated to drive the separation blade to descend. When the separation blade passes between the ends of the two wires, the ends of the two wires that are stuck together can be separated. The separation action is completed by inserting the blade of the separation blade into the joint between the ends of the wires. Finally, the second drive 24 is activated to drive the two seats 221 to move away from each other along the slide rail 241. When the distance between the two seats 221 is large enough, the wire pushing mechanism 3 can take out the separated wire ends from the positioning cavity 222 so that they can be sent to the next process.

[0065] according to Figure 5 and Figure 6 As shown, in a further embodiment, the lower end of the seat 221 is provided with a first inclined surface 224 that slopes inward from bottom to top, and the first inclined surfaces 224 of each seat 221 are arranged opposite to each other; the second driving member 24 includes a cylinder 242 and two pushing blocks 243; the pushing blocks 243 are provided with a second inclined surface 244 corresponding to the first inclined surface 224; the cylinder 242 is disposed on the first support frame 21 and is drivenly connected to each pushing block 243.

[0066] Specifically, the piston rod of cylinder 242 retracts to move the piston rod back to its original position. At this time, under the pushing action of the third drive member 25, each seat 221 moves along the slide rail 241 so that each push block 243 moves closer to each other until the two seats 221 fit together to form a complete positioning cavity 222. At this time, the separation knife is used to fix the ends of each wire. Conversely, when the piston rod of cylinder 242 begins to extend, the extension action of the piston rod drives each push block 243 to move upward, that is, to move upward along the axis of cylinder 242. At this time, the second inclined surface 244 of the push block 243 and the first inclined surface 224 of the seat 221 are tightly fitted again. As the push block 243 moves further upward, the force transmission between the inclined surfaces causes the seat 221 to move inward along the slide rail 241. Since the first inclined surface 224 and the second inclined surface 244 are tightly fitted, they play the role of converting the linear motion of the push block 243 into the oblique movement of the seat 221, thereby causing the two seats 221 to move away from each other. As the distance between the two seats 221 gradually increases, until the distance between the two seats 221 is sufficient to provide enough space for inserting or removing the wire, the wire pushing mechanism 3 can push the end of the wire to pass through the positioning cavity 222.

[0067] according to Figure 6 As shown, in a further embodiment, the third driving member 25 includes two elastic members 245 and two fixing blocks 246; each fixing block 246 is fixedly disposed on the slide rail 241; the two ends of the elastic member 245 are respectively connected to the corresponding seat 221 and fixing block 246.

[0068] Specifically, the elastic element 245 provides thrust to drive the seats 221 closer together. The fixing block 246 fixes one end of the elastic element 245, providing a stable support point for that end. When the second drive element 24 has driven the two seats 221 to a position away from each other, providing sufficient space for inserting the wire, the elastic element 245 is in a stretched state. However, due to the action of the second drive element 24, the seats 221 remain in the separated position, allowing the end of the wire to be inserted between the two seats 221. Conversely, when the cylinder 242 of the second drive element 24 drives the pressing block 243 to descend along the axis of the cylinder 242, as the pressing block 243 descends, the second inclined surface 244 of the pressing block 243 and the first inclined surface of the seat 221... As the force transmission between surfaces 224 gradually decreases, the pushing force of the second driving member 24 gradually decreases. At this time, the elastic member 245 generates a certain pushing force during the process of returning to its original shape, which is transmitted to the seat 221. This drives each seat 221 to move closer to each other along the slide rail 241 until the cavity wall of the positioning cavity 222 abuts against the end of the wire. When the two seats 221 are completely close, the end of the wire is fixed in the positioning cavity 222. Since the inner wall of the positioning cavity 222 is in close contact with the outer side of the wire, it ensures that the wire is unlikely to shake violently in subsequent operations. In this way, the elastic member 245 continuously provides a certain elastic force, thereby ensuring that each seat 221 is kept in the designated position. Moreover, since the elastic force of the elastic member 245 is relatively moderate, damage to the end of the wire can be avoided.

[0069] It is understood that the elastic element 245 in this embodiment of the present invention is a spring.

[0070] according to Figure 3 As shown, in some specific embodiments, the wire pushing mechanism 3 includes a pushing component 31, a support base 36, a wire clamping component 32, and a wire end clamping component 33; the wire clamping component 32 and the wire end clamping component 33 are both disposed on the support base 36; the pushing component 31 is disposed on the top of the workbench 1 and is drivenly connected to the support base 36.

[0071] Specifically, the pushing component 31 is the power source for the wire pushing mechanism 3, used to drive the carrier 36 to move along the guide rail of the worktable 1. The carrier 36 is the core component of the wire pushing mechanism 3, used to install and support the wire clamping component 32 and the wire end clamping component 33. The wire clamping component 32 clamps the main body of the wire, ensuring the wire remains stable during pushing. The wire end clamping component 33 precisely clamps the end of the wire, preventing the wire end from shifting during pushing.

[0072] according to Figure 3As shown, specifically, the wire clamping assembly 32 includes a fourth driving member 34 and two first clamping parts 35; the fourth driving member 34 is disposed on the support base 36 and is drivenly connected to each of the first clamping parts 35; the wire end clamping assembly 33 includes a fifth driving member and two second clamping parts; the fifth driving member is disposed on the support base 36 and is drivenly connected to each of the second clamping parts.

[0073] Specifically, a fourth driving member 34 is disposed on the support 36 and is used to drive the opening and closing of the two first clamping parts 35, which are used to clamp the wire. The fourth driving member 34 drives the two first clamping parts 35 to rotate until they can approach each other, gradually clamping the wire. Driven by the pushing component 31, the support 36 moves along the guide rail of the worktable 1, and the wire clamping component 32 moves with the support 36. Throughout the pushing process, the fourth driving member 34 maintains a certain clamping force, ensuring that the main body of the wire is stably clamped between the two first clamping parts 35. A fifth driving member is disposed on the support assembly and is used to drive the opening and closing of the two second clamping parts, which are used to clamp the end of the wire. When the end of the wire is placed between the two second clamping parts, within the clamping range of the clamping parts, the fifth driving member drives the two second clamping parts to rotate until they gradually approach the end of the wire. When the two second clamping parts are completely closed, the end of the wire is firmly clamped between the two clamping parts. Driven by the pushing component 31, the carrier 36 moves along the guide rail of the worktable 1, and the wire end clamping component 33 moves together with the carrier 36. Throughout the pushing process, the fifth driving component maintains a certain clamping force to ensure that the wire end is stably clamped between the two second clamping parts. Therefore, the wire clamping component 32 and the wire end clamping component 33 need to work together during the pushing process, while controlling the actions of the fourth driving component 34 and the fifth driving component to ensure that the main body of the wire and the wire end remain stable during the pushing process, so as to ensure that the wire end can stably pass through the positioning cavity 222.

[0074] It is understood that the fourth driving component 34 and the fifth driving component in this embodiment of the present invention can both be HFR cylinder 242.

[0075] according to Figure 7 As shown, in some specific embodiments, the heat shrink tubing assembly mechanism 4 further includes a second support frame 44, a first roller assembly 45, and a second roller assembly 48; the second support frame 44 is disposed on the worktable 1; each roller assembly 45 is disposed on the second support frame 44, and the heat shrink tubing is conveyed between the two sets of roller assemblies 45; the cutting assembly 42 is disposed on the second support frame 44.

[0076] Specifically, the second support frame 44 is disposed on the workbench 1 and is used to support and fix the components on the heat shrink tubing transport path, such as the roller assembly 45 and the cutting assembly 42. Each roller assembly consists of multiple rollers for supporting and guiding the transport of the heat shrink tubing. The first roller assembly 45 and the second roller assembly 48 are located on the upper and lower sides of the heat shrink tubing, respectively, to ensure that the heat shrink tubing remains stable during transport. The heat shrink tubing feeding assembly 41 is responsible for transporting the heat shrink tubing from the storage location to the heat shrink tubing assembly mechanism 4. When the heat shrink tubing feeding assembly 41 conveys the heat shrink tubing, the heat shrink tubing is clamped and guided by the first roller assembly 45 and the second roller assembly 48. When the heat shrink tubing reaches the clamping position of the heat shrink tubing clamping assembly 43, the heat shrink tubing clamping assembly 43 is activated to clamp the end of the heat shrink tubing. After clamping the heat shrink tubing, the heat shrink tubing clamping assembly 43 moves along the direction of the positioning seat 22 to stretch the heat shrink tubing to a position close to the end of the wire. The first roller assembly 45 and the second roller assembly 48 continue to support and guide the heat shrink tubing during the stretching process to ensure that the heat shrink tubing does not shift or twist during the stretching process. During the movement, the heat shrink tubing clamping assembly 43 moves the clamped heat shrink tubing toward the end of the wire and accurately aligns the end of the heat shrink tubing with the end of the wire. When the heat shrink tubing is stretched close to the end of the wire, the heat shrink tubing clamping assembly 43 continues to move to accurately fit the heat shrink tubing onto the outside of the end of the wire.

[0077] With this configuration, the outer side of the heat shrink tubing is simultaneously clamped by the first roller assembly 45 and the second roller assembly 48. Under the guidance of the roller assembly 45, the heat shrink tubing can be transported smoothly and supported to prevent it from deforming or shifting due to its own weight or external force during transport. Moreover, under the guidance of each roller assembly 45, the heat shrink tubing can be moved smoothly to the clamping position of the heat shrink tubing clamping assembly 43.

[0078] Specifically, the first roller assembly 45 includes a sixth driving member 451, a driving roller 452 and a first driven roller 453; the driving roller 452 and the first driven roller 453 are both rotatably mounted on the second support frame 44, and the sixth driving member 451 is mounted on the second support frame 44 and is drivenly connected to the driving roller 452.

[0079] Specifically, when the sixth drive unit 451 is activated, it transmits power to the drive roller 452, which then begins to rotate under the drive of the sixth drive unit 451. Due to the friction between the drive roller 452 and the surface of the heat shrink tubing, the heat shrink tubing is driven forward. As the heat shrink tubing moves forward under the drive of the drive roller 452, it simultaneously comes into contact with the first driven roller 453. The first driven roller 453 is driven to rotate by the conveying of the heat shrink tubing and works in coordination with the drive roller 452 to ensure the smooth conveying of the heat shrink tubing. Guided by the drive roller 452 and the first driven roller 453, the heat shrink tubing is smoothly conveyed forward. Finally, when the heat shrink tubing is conveyed to the clamping position of the heat shrink tubing clamping assembly 43, the sixth drive unit 451 stops working, causing the drive roller 452 and the first driven roller 453 to stop rotating. At this time, the heat shrink tubing clamping assembly 43 is activated, clamping the end of the heat shrink tubing, preparing for the next step of stretching and assembling the heat shrink tubing.

[0080] It should be noted that, since the surfaces of the driving roller 452 and the first driven roller 453 generate a certain friction when in contact with the outer side of the heat shrink tubing, it can be ensured that the heat shrink tubing is unlikely to slip or deviate during transport.

[0081] It is understood that the sixth driving component 451 of this utility model embodiment includes a motor, a transmission belt, a driving gear and a driven gear; the driving gear is fixedly sleeved on the power output shaft of the motor, the driven gear is sleeved on the connecting shaft of the driving roller 452, and the transmission belt sleeves the driving gear and the driven gear. When the motor drives the driving gear to rotate, the driven gear can be driven to rotate synchronously through the transmission belt, and the driving roller 452 will rotate accordingly.

[0082] according to Figure 8 As shown, in a further embodiment, the second support frame 44 is provided with a vertical slide rail 46; the second support frame 44 is provided with a vertical slide rail 46; the second roller assembly 48 includes a seventh driving member 454, a moving block 455, and a second driven roller 456; the second driven roller 456 is connected to the moving block 455, and the moving block 455 is movably disposed on the vertical slide rail 46; the seventh driving member 454 is drivenly connected to the moving block 455, and can drive the second driven roller 456 to approach or move away from the driving roller 452.

[0083] Specifically, the heat shrink tubing is transported between the driving roller 452 of the first roller assembly 45 and the second driven roller 456 of the second roller assembly 48. When the seventh driving member 454 is activated, it drives the moving block 455 to move up and down along the vertical slide rail 46. Under the drive of the seventh driving member 454, the moving block 455 moves along the vertical slide rail 46, causing the second driven roller 456 to move closer to or away from the driving roller 452.

[0084] For example, when it is necessary to increase the tension of the heat shrink tubing or adjust the conveying path, the seventh drive member 454 drives the moving block 455 downward, causing the second driven roller 456 to approach the active guide roller until the heat shrink tubing is tightened, thus increasing the tension. This is necessary when the heat shrink tubing requires high-precision conveying without any looseness, such as before the heat shrink tubing clamping assembly 43 clamps it, to ensure the heat shrink tubing is taut for accurate clamping. Conversely, when it is necessary to loosen the heat shrink tubing or adjust the conveying path, the seventh drive member 454 drives the moving block 455 upward, causing the second driven roller 456 to move away from the active roller 452. This reduces the tension on the heat shrink tubing, making it more relaxed, thereby reducing friction during conveying or preventing overstretching. Therefore, when the heat shrink tubing needs to pass through a complex conveying path or when overstretching needs to be avoided, such as in the initial stage of conveying the heat shrink tubing from the storage location to the conveying path, reducing the tension of the heat shrink tubing can prevent damage due to overstretching.

[0085] In addition, when the second driven roller 456 approaches the driving roller 452, the position of the heat shrink tubing is fixed between the two rollers, which also ensures that the heat shrink tubing is unlikely to shift during transport.

[0086] according to Figure 9 As shown, in a further embodiment, the heat shrink tubing assembly mechanism 4 also includes a guide member 47, which is disposed on the second support frame 44 and has a guide hole through which the heat shrink tubing moves.

[0087] Specifically, the shape and size of the guide hole match the outer diameter of the heat shrink tubing. The heat shrink tubing passes through the guide hole during transport. Since the guide hole provides a fixed transport path for the heat shrink tubing, ensuring it always moves in the predetermined direction and preventing deviation or twisting, it ensures that the heat shrink tubing moves along the predetermined direction. For example, when the cutting assembly 42 cuts the heat shrink tubing, one of the guide members 47 is located beside the cutting assembly 42. The guide hole fixes the position of the heat shrink tubing, ensuring that the cutting assembly 42 can accurately cut the heat shrink tubing at the designated position. Moreover, the inner wall of the guide hole can apply a certain supporting force to the heat shrink tubing, preventing it from shaking or shifting during the cutting process.

[0088] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
