Description

Technical Field

[0001] This application relates to the field of conduit installation equipment, and in particular to a heat shrink tubing installation equipment for wire harnesses. Background Technology

[0002] Wire harnesses are the overall system of service equipment for a given load source group, such as trunk lines, switching devices, and control systems. Wire harnesses require terminals to connect various devices for data communication. Ordinary terminals are crimped and fixed to the wire harness as a single unit, leaving the connection point relatively weak. Therefore, heat shrink tubing is typically used at the connection point. Heating the heat shrink tubing causes it to shrink and deform, allowing both ends to connect stably to the wire harness and the crimp connector, respectively.

[0003] Heat shrink tubing is generally used in one piece. The end of the wire harness is first inserted into one end of the heat shrink tubing, and then the end of the heat shrink tubing is cut off. This achieves the effect of putting the heat shrink tubing on the wire harness. Finally, the terminals are connected. However, inserting the wire harness into the heat shrink tubing manually requires too much effort. When the machine is cutting, the diameter of the heat shrink tubing opening is small compared to the outer diameter of the wire harness, requiring high precision to complete the insertion. The accuracy is difficult to control, and the operation is cumbersome. Summary of the Invention

[0004] To address the challenge of achieving precise tubing insertion, this application provides a heat shrink tubing insertion device for wire harnesses.

[0005] The heat shrink tubing insertion device for wire harnesses provided in this application adopts the following technical solution: A heat shrink tubing insertion device for wire harnesses includes a frame, on which a translation mechanism, a cutting mechanism, a conveying mechanism, and a guide are also provided. The output end of the translation mechanism is provided with a clamping mechanism for holding the wire harness, and the clamping mechanism is slidably connected to the frame. The conveying mechanism is used to convey the heat shrink tubing, and the output end of the conveying mechanism is located on the same plane as the clamping mechanism on the frame. The guide is installed on the travel path of the heat shrink tubing and is located on the side of the conveying mechanism. The output end of the cutting mechanism, the output ends of the conveying mechanism, the clamping mechanism, and the guide are all located on the same horizontal line, so that the heat shrink tubing and the wire harness are on the same horizontal line. The output end of the clamping mechanism clamps the wire harness, the output end of the translation mechanism drives the clamping mechanism to move towards the cutting mechanism, and the output end of the conveying mechanism drives the heat shrink tubing along the guide to penetrate the cutting mechanism, so that after the wire harness and the heat shrink tubing are inserted, the cutting mechanism cuts them.

[0006] By adopting the above technical solution, the conveying mechanism clamps the heat shrink tubing and provides the conveying of the heat shrink tubing, the clamping mechanism holds the wire harness, the cutting mechanism is located between the conveying mechanism and the heat shrink tubing, and the translation mechanism drives the clamping mechanism to move towards the cutting mechanism. During the movement, the heat shrink tubing is stabilized by the guide component to make the wire harness and the heat shrink tubing be on the same horizontal straight line, so that the wire harness can be inserted into the heat shrink tubing more stably, and then cut by the cutting mechanism to achieve the function of accurate and stable automatic tubing insertion and cutting.

[0007] Optionally, the cutting mechanism includes a cutting drive, a fixed cutting component, and a movable cutting component; the fixed cutting component is mounted on the frame and on the same side as the translation mechanism; the cutting drive is mounted above the fixed cutting component; the movable cutting component is mounted at the output end of the cutting drive, and the movable cutting component and the fixed cutting component are in the same vertical plane.

[0008] By adopting the above technical solution, the moving cutting component is driven by the cutting drive component to move towards the fixed cutting component, so that the wire harness and heat shrink tubing located between the moving cutting component and the fixed cutting component and after insertion are cut off, so that manual cutting is not required, thus ensuring safety and improving convenience.

[0009] Optionally, the conveying mechanism includes a first pressure roller, a second pressure roller, a conveying drive component, and a tensioning drive component; the conveying drive component is mounted on the side of the frame away from the translation mechanism, and the output end of the conveying drive component extends through the frame to the same side as the horizontal mechanism; the first pressure roller is connected to the output end of the conveying drive component; the tensioning drive component is mounted on the same side as the translation mechanism, and the tensioning drive component is located above the first pressure roller; the second pressure roller is connected to the output end of the tensioning drive component.

[0010] By adopting the above technical solution, the output end of the tension drive can drive the second pressure roller to move towards the first pressure roller, the output end of the conveying drive can drive the first pressure roller to rotate, the heat shrink tube is located between the first pressure roller and the second pressure roller, as the second pressure roller gradually approaches the first pressure roller, the heat shrink tube is clamped by the first pressure roller and the second pressure roller, and under the rotation drive of the first pressure roller, the second pressure roller follows and rolls.

[0011] Optionally, the clamping mechanism includes a bidirectional drive and a clamping member; the bidirectional drive is connected to the output end of the translation mechanism and has two output ends; there are two clamping members, which are sequentially installed on the two output ends of the bidirectional drive, and each clamping member has a half-opening. The bidirectional drive drives the two clamping members to move towards each other so that the two openings overlap to form a complete clamping opening.

[0012] By adopting the above technical solution, when the two clamping components clamp the wire harness, the wire harness is clamped in the complete clamping opening. The clamping components clamp or release the wire harness as the two output ends of the bidirectional drive extend or retract, so as to achieve the effect of mechanical clamping.

[0013] Optionally, it also includes an adjustment mechanism; the adjustment mechanism includes a first adjustment member and a second adjustment member, the first adjustment member being connected to the clamping mechanism; the second adjustment member is installed on the cutting mechanism, and the positions of the first adjustment member and the second adjustment member are opposite to each other.

[0014] By adopting the above technical solution, the heat shrink tubing and wire harness are stabilized by adjusting the mechanism to avoid misalignment and inaccurate connection.

[0015] Optionally, the first adjusting component is an adjusting drive component and a positioning component; the adjusting drive component is connected to the output end of the translation mechanism, and the output end of the adjusting drive component is connected to the clamping mechanism; the positioning component is connected below the clamping point of the clamping mechanism, and the positioning direction of the positioning component is opposite to the cutting mechanism, and the positioning component is electrically connected to the adjusting drive component; the second adjusting component is a reflective component, and the reflective component extends towards the fixed cutting component near the translation mechanism.

[0016] By adopting the above technical solution, when the clamping mechanism clamps the wire harness, the positioning component emits an infrared beam to the reflector. If the heat shrink tubing extends a long length after passing through the moving and fixed cutting components, the heat shrink tubing is greatly affected by the torque and will sag. After sag, it will block part of the reflector. The positioning component cannot receive the reflected signal, indicating that the wire harness cannot be docked with the heat shrink tubing. Therefore, by adjusting the height of the clamping mechanism by adjusting the driving component until the positioning component receives the reflected signal, the driving component is stopped. The translation mechanism can then drive the clamping mechanism and the clamped wire harness to move towards the heat shrink tubing, so that the wire harness and the heat shrink tubing can be docked, thus improving the stability of the docking.

[0017] Optionally, the first adjusting component is a first adjusting plate and a first spring; the first adjusting plate is used to provide support for the heat shrink tubing, and the first adjusting plate is slidably connected to the side of the cutting mechanism near the output end of the clamping mechanism; one end of the first spring is connected to the first adjusting plate, and the other end is connected to the cutting mechanism; the second adjusting component is a second adjusting plate and a second spring; two second adjusting plates are provided, and the two second adjusting plates are combined to provide support for the wire harness, and the second adjusting plates are slidably connected to the output end of the clamping mechanism; the second springs correspond to the second adjusting plates, and there are two of them, and one end of the two second springs is connected to the corresponding second adjusting plate, and the other end is connected to the output end of the clamping mechanism.

[0018] By adopting the above technical solution, when the wire harness is clamped by the two clamping members, the extended part is abutted by the two second adjusting plates. When the heat shrink tubing extends from the cutting mechanism to the clamping mechanism, the first adjusting plate abuts against the bending direction to avoid bending of the wire harness and heat shrink tubing. When the clamping mechanism moves towards the cutting mechanism under the drive of the translation mechanism, the wire harness moves with the clamping plate and is inserted into the heat shrink tubing. At the same time, the two second adjusting plates abut against the first adjusting plate, and the two exert force on each other, causing the first adjusting plate to move along the first sliding port and the second adjusting plate to move towards the second sliding port. This ensures that the two do not affect each other when the wire harness and heat shrink tubing are inserted, thereby stabilizing the position of the wire harness and heat shrink tubing and preventing displacement.

[0019] Optionally, the cutting mechanism has a first sliding port through which the first adjusting plate passes; the output end of the clamping mechanism has a second sliding port through which the two second adjusting plates pass.

[0020] By adopting the above technical solution, the first sliding port and the second sliding port provide support and guidance for the first adjustment plate and the second adjustment plate.

[0021] Optionally, a first pad is provided at the first sliding port near the conveying mechanism, and a second pad is provided at the second sliding port away from the cutting mechanism.

[0022] By adopting the above technical solution, the first pad and the second pad can provide additional support for the first adjustment plate and the second adjustment plate, avoiding insufficient support for the cutting mechanism close to the first sliding port and insufficient support for the output end of the clamping mechanism at the second sliding port.

[0023] Optionally, the first adjustment plate has a first curved groove that matches the outer diameter of the heat shrink tubing; the second adjustment plate has a second curved groove that matches the outer diameter of the wire harness.

[0024] By adopting the above technical solution, the first curved groove and the second curved groove can respectively prevent the heat shrink tubing and the wire harness from shifting in the horizontal direction.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying mechanism clamps the heat shrink tubing and provides the conveying of the heat shrink tubing. The clamping mechanism holds the wire harness. The cutting mechanism is located between the conveying mechanism and the heat shrink tubing. The translation mechanism drives the clamping mechanism to move toward the cutting mechanism. During the movement, the heat shrink tubing is stabilized by the guide component to keep the wire harness and the heat shrink tubing on the same horizontal straight line, ensuring that the wire harness can be inserted into the heat shrink tubing more stably. The cutting mechanism then cuts the wire harness, achieving the function of accurate and stable automatic tubing insertion and cutting. 2. The positioning component emits an infrared beam to the reflector. If the heat shrink tubing droops, it will block part of the reflector. If the positioning component does not receive the reflected signal, it means that the wire harness cannot dock with the heat shrink tubing. The height of the clamping mechanism is adjusted by adjusting the driving component until the positioning component receives the reflected signal. Then the driving component is adjusted and the translation mechanism can drive the clamping mechanism and the clamped wire harness to move towards the heat shrink tubing, so that the wire harness and the heat shrink tubing can dock, which improves the stability of the docking. 3. After the wire harness is clamped by the two clamping members, the extended part is held in place by the two second adjusting plates. When the heat shrink tubing extends from the cutting mechanism to the clamping mechanism, the first adjusting plate holds against the bending direction to prevent the wire harness and heat shrink tubing from bending. When the clamping mechanism moves towards the cutting mechanism under the drive of the translation mechanism, the wire harness moves with the clamping plate and is inserted into the heat shrink tubing. At the same time, the two second adjusting plates hold against the first adjusting plate. The two exert forces on each other, causing the first adjusting plate to move along the first sliding port and the second adjusting plate to move towards the second sliding port. This ensures that the two do not affect each other when the wire harness and heat shrink tubing are inserted, thereby stabilizing the position of the wire harness and heat shrink tubing and preventing displacement.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0028] This application discloses a heat shrink tubing insertion device for wire harnesses.

[0029] Example 1: A heat shrink tubing insertion device for wire harnesses, as described in the reference. Figure 1 The system includes a frame 1, which is further equipped with a translation mechanism 2, a cutting mechanism 3, a conveying mechanism 4, and a guide 7. The output end of the translation mechanism 2 is equipped with a clamping mechanism 5 for clamping the wire harness. The translation mechanism 2 includes a translation drive and a connecting frame. The connecting frame is installed on one side of the frame 1, and the translation drive is installed on the connecting frame. The translation drive can be any type of drive element, such as an electric push rod, a pneumatic cylinder, or an electric cylinder. No limitation is made here. The output end of the translation drive is equipped with the clamping mechanism 5, which clamps the wire harness that needs to be inserted into the heat shrink tubing.

[0030] Driven by the translation drive, the clamping mechanism 5 can slide along the frame 1. The clamping mechanism 5 includes a mounting frame, a lifting drive, a bidirectional drive 51, and a clamping member 52. The mounting frame provides support and mounting points. The lifting drive is mounted on the side of the mounting frame. The bidirectional drive 51 is mounted on the output end of the lifting drive. The lifting drive can be an electric push rod, a cylinder, an electric cylinder, or other driving element, and there is no limitation here. The bidirectional drive 51 can be a bidirectional electric push rod. The clamping member 52 can be a clamping plate with openings on it. The clamping port matches the wire harness, and two clamping plates are provided, which are installed sequentially on the two output ends of the bidirectional electric push rod. Therefore, the clamping port 53 on each clamping plate is a half-opening. When the two clamping plates clamp the wire harness, the wire harness is clamped in the two half-opening clamping ports 53. The clamping plates clamp or release the wire harness as the two output ends of the bidirectional electric push rod extend or retract. The upgraded drive unit can drive the bidirectional electric push rod to rise and fall vertically to adjust the position of the clamping port 53 on the clamping plate and improve the accuracy of wire threading.

[0031] The translation mechanism 2 and the clamping mechanism 5 can be connected by a sliding seat 8, which consists of a slide rail 81 and a slider 82. The output end of the translation mechanism 2 is connected to one end of the slider 82, and the clamping mechanism 5 is connected to the other end of the slider 82. This allows the output end of the translation mechanism 2 to drive the slider 82, thereby driving the clamping mechanism 5 to translate along the slide rail 81. The sliding seat 8 ensures the stability of the translation of the clamping mechanism 5 and improves the accuracy of tube insertion.

[0032] Reference Figure 2As shown, the conveying mechanism 4 is used to convey heat shrink tubing, and the output end of the conveying mechanism 4 and the clamping mechanism 5 are located on the same plane as the frame 1. Guide members 7 can be set on both sides of the conveying mechanism 4. The guide members 7 can be cylindrical or block-shaped with guide holes for the heat shrink tubing to pass through. The heat shrink tubing passes through the guide members 7 to fix the travel path, and the number of guide members 7 is determined according to the length of the heat shrink tubing. The heat shrink tubing passes through the guide members 7 and connects to the output end of the conveying mechanism 4. The conveying mechanism 4 can be a roller conveyor. The roller conveyor mainly consists of a first pressure roller 41, a second pressure roller 42, a conveying drive member 43, and a tensioning drive member 44. The conveying drive member 43 can be a drive motor, and the tensioning drive member 44 can be a lifting cylinder. The drive motor is installed on the side of the frame 1 away from the translation mechanism 2, and the output end of the drive motor passes through the frame 1. Extending to the same side as the horizontal mechanism, the first pressure roller 41 is connected to the output end of the drive motor. The lifting cylinder is installed on the same side as the translation mechanism 2, and is located directly above the first pressure roller 41. The second pressure roller 42 is connected to the output end of the lifting cylinder, so that the output end of the lifting cylinder can drive the second pressure roller 42 to move towards the first pressure roller 41. The output end of the drive motor drives the first pressure roller 41 to rotate. The heat shrink tubing is located between the first pressure roller 41 and the second pressure roller 42. When the second pressure roller 42 gradually approaches the first pressure roller 41, the heat shrink tubing is clamped by the first pressure roller 41 and the second pressure roller 42. Under the rotation drive of the first pressure roller 41, the second pressure roller 42 follows and rolls, and the heat shrink tubing is subjected to force and moves towards the cutting mechanism 3. It is guided by the guide member 7 to avoid deviation of the travel path, so as to achieve the function of accurately replacing the heat shrink tubing.

[0033] Reference Figure 3 As shown, the heat shrink tubing is transported by the conveying mechanism 4 and moves from the cutting mechanism to the clamping mechanism. The cutting mechanism 3 includes a cutting drive 31, a fixed cutting component 32, and a moving cutting component 33. The fixed cutting component 32 can be a fixed cutter, which is directly mounted on the frame 1 and on the same side as the translation mechanism 2. The cutting drive 31 is mounted above the fixed cutter. The moving cutting component 33 is mounted at the output end of the cutting drive 31, and the moving cutting component 33 and the fixed cutting component 32 are on the same vertical plane. The moving cutting component 33 can be a moving cutter. The output end of the cutting drive 31 drives the moving cutter to move towards the fixed cutter. Both the fixed cutter and the moving cutter have sharp cutting edges in opposite directions to cut the heat shrink tubing containing the wire harness.

[0034] A sliding seat 8 can also be provided between the cutting drive 31 and the moving cutter. The sliding seat 8 stabilizes the movement of the moving cutter and reduces the occurrence of uneven cuts due to deviation during the cutting process.

[0035] The cutting surface of the fixed cutter, the top surface of the first pressure roller 41, and the clamping opening 53 of the clamping plate are all located on the same horizontal straight line, so that the heat shrink tube and the wire harness can be inserted on the same horizontal straight line, thereby improving the accuracy and stability of tube cutting.

[0036] The implementation principle of Embodiment 1 of this application includes: the conveying mechanism 4 clamps the heat shrink tubing and provides the conveying of the heat shrink tubing; the clamping mechanism 5 clamps the wire harness; the cutting mechanism 3 is located between the conveying mechanism 4 and the heat shrink tubing; the translation mechanism 2 drives the clamping mechanism 5 to move towards the cutting mechanism 3; during the movement, the heat shrink tubing is stabilized by the guide 7 to make the wire harness and the heat shrink tubing be on the same horizontal straight line, so that the wire harness can be inserted into the heat shrink tubing more stably, and is cut by the cutting mechanism 3, so as to achieve the function of accurate and stable automatic tubing insertion and cutting.

[0037] Example 2: Reference Figure 4 As shown, this embodiment 2 adds the following content based on embodiment 1, including an adjustment mechanism 6; the adjustment mechanism 6 includes a first adjustment member 61 and a second adjustment member 62, the first adjustment member 61 is connected to the clamping mechanism 5; the second adjustment member 62 is installed on the cutting mechanism 3, and the positions of the first adjustment member 61 and the second adjustment member 62 are opposite; since the heat shrink tubing and wire harness ports are small in size and soft in material, they are prone to misalignment during insertion, making accurate docking difficult. Therefore, the adjustment mechanism 6 is used to stabilize the heat shrink tubing and wire harness to avoid misalignment and inaccurate docking.

[0038] Specifically, the first adjusting member 61 consists of an adjusting drive member 6111 and a positioning member 6112; the adjusting drive member 6111 is connected to the output end of the translation mechanism 2, and the output end of the adjusting drive member 6111 is connected to the clamping mechanism 5; the positioning member 6112 is connected to the lower part of the clamping point of the clamping mechanism 5, and the positioning direction of the positioning member 6112 is opposite to that of the cutting mechanism 3, and the positioning member 6112 is electrically connected to the adjusting drive member 6111; the second adjusting member 62 is a reflective member 6211, which extends downwards towards the fixed cutter.

[0039] The adjustment drive component 6111 can be an electric push rod, cylinder, electric cylinder, or other drive element, and there are no restrictions on its use. The positioning component 6112 can be an infrared positioner, and the reflector 6211 can be a reflector with a relatively long vertical length, the specific length of which needs to meet the vertical height of the heat shrink tubing after bending. The infrared positioner emits infrared light, and when the infrared light emitted by the infrared positioner comes into contact with the reflector, it is reflected back to the infrared positioner. The infrared positioner can determine its position after receiving the reflected infrared light. When the two clamping plates clamp the wire harness, only a portion of the wire harness head needs to be exposed to ensure that the torque between the wire harness head and the clamping plates does not cause the wire harness head to droop and bend, thus preventing it from blocking the infrared rays emitted by the infrared locator. When the heat shrink tubing is bent, the infrared locator will be blocked by the bent heat shrink tubing. Therefore, by adjusting the drive component 6111, the bidirectional drive component 51 is moved vertically until the blocked infrared rays can illuminate the reflector, so that the infrared locator can receive the infrared signal reflected by the reflector, thereby stopping the operation of the adjustment drive component 6111 to adjust the height of the clamping plates. At this time, the position of the wire harness head and the position of the heat shrink tubing after it droops are on the same horizontal straight line, so the wire harness head can be inserted into the heat shrink tubing.

[0040] A bending drive can be installed on the bidirectional drive 51, and the bending drive is connected to an external controller signal. The bending drive can be a drive turntable, which can drive the bidirectional drive 51 to tilt, thereby tilting the clamping plate and the wire harness. Since the heat shrink tubing will be at an angle after bending, it may cause inaccurate docking. Therefore, in order to improve accuracy, it can be adjusted by the bending drive.

[0041] When the infrared locator receives the infrared reflected signal, it transmits the lifting data to the back-end controller via an electrical signal. The controller calculates the bending degree of the heat shrink tubing and sends an electrical signal to control the bending drive to drive the bidirectional drive 51 to bend, so that the wire harness head and the opening of the heat shrink tubing are at the same bending angle, thereby improving the docking accuracy.

[0042] The implementation principle of Embodiment 2 of this application includes: when the clamping mechanism 5 clamps the wire harness, and the wire harness head only needs to extend through the clamping mechanism 5, so that the torque on one end of the wire harness head is small, the wire harness itself can withstand the torque on one end of the wire harness head and will not bend, at this time the positioning member 6112 emits an infrared beam to the reflector 6211. If the heat shrink tube extends a long length after passing through the cutting mechanism, the heat shrink tube will sag under the influence of force. After sag, it will block part of the reflector 6211. The positioning member 6112 cannot receive the reflected signal, indicating that the wire harness cannot be docked with the heat shrink tube. The height of the clamping mechanism 5 is adjusted by adjusting the driving member 6111 until the positioning member 6112 is adjusted. After receiving the reflected signal, 112 stops adjusting the drive component 6111. The translation mechanism 2 then drives the clamping mechanism 5 and the clamped wire harness to move towards the heat shrink tubing, enabling the wire harness to connect with the heat shrink tubing and improving the stability of the connection. After connection, the clamping mechanism 5 loosens slightly, allowing the wire harness to slide along the clamping mechanism 5. The translation mechanism 2 then drives the clamping mechanism 5 to move away from the cutting mechanism 3 until the required insertion length of the wire harness is reached. The clamping mechanism 5 then clamps the wire harness again, and the translation mechanism 2 drives the clamping mechanism 5 to insert the wire harness into the heat shrink tubing. Subsequently, the cutting mechanism 3 cuts the wire harness, thus achieving the effect of controlling the required insertion length.

[0043] Example 3 Refer to 5 and Figure 6 As shown, this embodiment 3 is another implementation of embodiment 2, and the specific contents are as follows: the first adjusting member 61 is the first adjusting plate 6121 and the first spring 6122; the second adjusting member 62 is the second adjusting plate 6221 and the second spring 6222.

[0044] The first adjusting plate 6121 is used to provide support for the heat shrink tubing, and the first adjusting plate 6121 is slidably connected to the side of the cutting mechanism 3 near the output end of the clamping mechanism 5; two second adjusting plates 6221 are provided, and the two second adjusting plates 6221 are combined to provide support for the wire harness, and the second adjusting plates 6221 are slidably connected to the output end of the clamping mechanism 5; one end of the first spring 6122 is connected to the first adjusting plate 6121, and the other end is connected to the cutting mechanism 3; two second springs 6222 are provided, corresponding to the second adjusting plates 6221, and one end of the two second springs 6222 is connected to the corresponding second adjusting plate 6221, and the other end is connected to the output end of the clamping mechanism 5.

[0045] The second adjustment plate 6221 is a half anti-deviation plate. The two second adjustment plates 6221 are respectively installed on the two clamping plates and located below the clamping opening 53. When the two clamping plates approach each other and clamp the wire harness, the two second adjustment plates 6221 come together to form a complete anti-deviation plate. After the two clamping plates clamp the wire harness, the part of the wire harness that extends out is supported by the complete anti-deviation plate formed by the combination of the two second adjustment plates 6221. The first adjustment plate 6121 supports the extended heat shrink tubing. The first adjustment plate 6121 and the second adjustment plate 6221 are both made of rigid materials, so they can withstand the soft and drooping heat shrink tubing and wire harness, thereby improving the accuracy of the connection between the wire harness and the heat shrink tubing.

[0046] However, the first adjusting plate 6121 and the second adjusting plate 6221 need to extend a certain distance to provide the heat shrink tubing and wire harness with the effect of resisting the adjustment offset. When the two move relative to each other, they will abut against each other, causing the translation mechanism 2 to be unable to drive the clamping mechanism 5 to continue moving. Therefore, a first sliding opening 6123 is opened on the fixed blade. The first adjusting plate 6121 can pass through the first sliding opening 6123, so that the first adjusting plate 6121 is slidably connected to the fixed blade through the first sliding opening 6123. Then, it is reset by the first spring 6122. A first spring 6122 can be used. One end of the first spring 6122 is connected to the first adjusting plate 6121, and the other end is connected to the fixed blade. When the first adjusting plate 6121 is squeezed and moves towards the conveying mechanism 4 along the first sliding port 6123, the first spring 6122 is stretched, thereby generating a force to reset the first adjusting plate 6121. When the first adjusting plate 6121 is no longer squeezed, the first adjusting plate 6121 is reset by the elastic force and moves towards the clamping mechanism 5 through the first sliding port 6123 to achieve the reset function.

[0047] After the two clamping plates are clamped together, a second sliding opening 6223 is opened, that is, each clamping plate has half of the second sliding opening 6223. The combined size of the second sliding openings 6223 matches the size of the second adjusting plate 6221. The second adjusting plate 6221 can slide through the clamping plate along its corresponding half of the second sliding opening 6223. The second spring 6222 can be a second spring 6222. One end of the second spring 6222 is connected to the second adjusting plate 6221, and the other end is connected to the corresponding clamping plate, thereby ensuring that the second adjusting plate 6221 can complete the reset under the elastic force of the second spring 6222.

[0048] A first pad 6124 is provided at the first sliding port 6123 near the side of the conveying mechanism 4, and a second pad 6224 is provided at the second sliding port 6223 away from the cutting mechanism 3. The function of the first pad 6124 and the second pad 6224 is to provide additional support for the first adjusting plate 6121 and the second adjusting plate 6221, so as to avoid insufficient support for fixing the cutter at the first sliding port 6123 and insufficient support for the clamping plate at the second sliding port 6223.

[0049] A first curved groove 6125 that matches the outer diameter of the heat shrink tubing is provided on the first adjustment plate 6121 to allow the heat shrink tubing to fit and prevent the heat shrink tubing from shifting in the horizontal direction; a second curved groove 6225 that matches the outer diameter of the wire harness is provided on the second adjustment plate 6221 to allow the wire harness to fit and prevent the wire harness from shifting in the horizontal direction.

[0050] The implementation principle of Embodiment 3 of this application includes: when the wire harness is clamped by the two clamping members 52, the extended portion is abutted by the two second adjusting plates 6221. When the heat shrink tubing extends from the cutting mechanism 3 to the clamping mechanism 5, the first adjusting plate 6121 abuts against the bending direction to prevent the wire harness and heat shrink tubing from bending. When the clamping mechanism 5 moves towards the cutting mechanism 3 under the drive of the translation mechanism 2, the wire harness moves with the clamping plates and is inserted into the heat shrink tubing. At the same time, the two second adjusting plates 6221 abut against the first adjusting plate 6121. 1. The two exert forces on each other, causing the first adjusting plate 6121 to move along the first sliding port 6123 and the second adjusting plate 6221 to move towards the second sliding port 6223. This ensures that the two do not interfere with each other when the wire harness is inserted into the heat shrink tubing, thereby stabilizing the position of the wire harness and the heat shrink tubing and preventing displacement. When the clamping mechanism 5 moves away from the cutting mechanism 3, the first spring 6122 and the second spring 6222 generate elastic force to reset the first adjusting plate 6121 and the second adjusting plate 6221.
