Description

Technical Field

[0001] This application relates to the field of power cable processing technology, and in particular to a cable heat shrink tubing position adjustment device. Background Technology

[0002] The processing of power cables typically involves a series of steps, including wire cutting, heat shrink tubing insertion, terminal crimping inspection, heat shrinking of the tubing, cable pre-storage, bundling and coiling, and binding. Before heat shrinking, the heat shrink tubing needs to be positioned precisely on the cable, such as at the cable end. However, in previous steps, the heat shrink tubing is merely loosely fitted onto the cable without being securely fixed. As the cable moves between workstations, the heat shrink tubing inevitably shifts relative to the cable, potentially causing its position on the cable to deviate from the pre-set heat shrinking point.

[0003] Therefore, there is an urgent need for a device that can precisely adjust the position of heat shrink tubing to achieve standardized positioning and installation of heat shrink tubing on cables. Summary of the Invention

[0004] This application provides a cable heat shrink tubing position adjustment device to solve the problem of inaccurate cable heat shrink tubing positioning.

[0005] The technical solution adopted in this application is as follows:

[0006] A cable heat shrink tubing position adjustment device, comprising:

[0007] The base is equipped with translation guide rails;

[0008] The lifting mechanism is slidably connected to the translation guide rail, and includes a translation slider, a power drive component and the lifting guide rail fixedly mounted on the translation slider;

[0009] An axial translation mechanism includes a linear displacement component arranged parallel to the translation guide rail. The linear displacement component is provided with a push plate, and the push plate is fixedly connected to the translation slider.

[0010] A rotary drive mechanism is slidably connected to a lifting guide rail and includes a rotary drive assembly, a connecting plate, and a rotating part. The connecting plate is fixedly connected to the power drive component.

[0011] A clamping and positioning assembly is fixed to the rotating part by a mounting bracket. The clamping and positioning assembly is coaxially arranged with the rotary drive mechanism. The clamping and positioning assembly includes:

[0012] The clamping base is provided with at least two guide grooves;

[0013] At least two movable grippers, each movable gripper slidingly engaging with a guide groove via a slider located at its end, and sensors are provided on the sidewalls of the movable grippers for detecting the position of the heat shrink tubing;

[0014] The gripper drive mechanism is located on the side wall of the gripper seat and is connected to each movable gripper through a linkage component. It is used to drive the movable grippers to move along the guide groove.

[0015] In some embodiments, the system further includes at least two lateral stabilizing jaws, which are connected to the movable jaw via a rotating shaft, and the lateral stabilizing jaws and the movable jaw are arranged parallel to each other along the axial direction.

[0016] In some embodiments, the gripping end of the movable gripper is provided with a V-shaped, U-shaped or arc-shaped gripping groove, and the inner surface of the gripping groove is provided with anti-slip texture in the form of a serrated or raised dot array.

[0017] In some embodiments, a limiting baffle is provided at the distal end of the clamping groove.

[0018] In some embodiments, there are two movable grippers arranged opposite each other, and the guide grooves are two sets of guide grooves arranged in parallel.

[0019] In some embodiments, the clamping and positioning assembly further includes a stabilizing guide rail that is engaged with the slider, and the stabilizing guide rail is fixedly connected to the mounting bracket or clamping seat.

[0020] In some embodiments, a control module is also included, which is signal-connected to the lifting mechanism, the axial translation mechanism, the rotary drive mechanism, and the clamping and positioning component to form a closed-loop control circuit.

[0021] In some embodiments, a pressure sensor is provided at the gripping end of the movable gripper, and the pressure sensor is signal-connected to the control module.

[0022] In some embodiments, the movable gripper includes:

[0023] The base body is rigidly connected to the slider at its ends;

[0024] The clamping block is detachably mounted to the end of the base.

[0025] The pre-tightening elastic component is connected to the base and the clamping block at both ends. The pre-tightening elastic component is equipped with adjusting bolts, which can be used to adjust the relative distance between the base and the clamping block.

[0026] In some embodiments, the lateral stabilizing gripper further includes:

[0027] The fine-tuning elastic element has a lateral stabilizing gripper at one end and a movable gripper at the other end.

[0028] A limiting protrusion protrudes into the limiting portion of the movable gripper to limit the rotation angle range of the lateral stabilizing gripper.

[0029] The beneficial effects of adopting the technical solution of this application are as follows:

[0030] As can be seen from the above technical solutions, the cable heat shrink tubing posture adjustment device shown in this application embodiment flexibly controls the lifting, translation, and rotation of the movable gripper around its axis through a lifting mechanism, an axial translation mechanism, and a rotary drive mechanism. By setting sensors to accurately measure the position and orientation of the heat shrink tubing, a closed-loop control for precise positioning of the heat shrink tubing by the movable gripper is formed, thereby ensuring the standardized positioning and installation of the heat shrink tubing on the cable. In the solution of this application, the cooperation of the translation guide rail, linear displacement component, and power drive component realizes the vertical lifting and horizontal axial translation of the clamping component, covering the longitudinal and lateral displacement requirements for heat shrink tubing adjustment. The rotating part is coaxially set with the clamping and positioning component, driving the heat shrink tubing to rotate around the cable axis, solving the problem of circumferential angle deviation of the heat shrink tubing, and realizing precise adjustment of the three-dimensional spatial orientation. The gripper drive mechanism drives the movable gripper to move along the guide groove through the linkage component, forming a symmetrical clamping force and avoiding cable deviation caused by unilateral force. In addition, the sensors on the side wall of the movable gripper detect the position and orientation of the heat shrink tubing, and form a closed-loop feedback with the control module to dynamically correct the clamping action and ensure positioning accuracy. By combining a multi-degree-of-freedom adjustment mechanism with closed-loop control, the heat shrink tubing achieves high positional adjustment accuracy, which is significantly better than traditional manual or mechanical limiting methods.

[0031] This application is applicable to heat shrink tubing positioning scenarios such as high-voltage cables and communication cables, meeting high-precision process requirements; it can be integrated into processes such as cable cutting, sleeve insertion, and heat shrinking, improving the continuity and intelligence level of the production line; through multi-mechanism collaborative control and sensor feedback mechanism, it significantly improves the positioning accuracy and stability of heat shrink tubing on cables, and to a certain extent reduces the economic cost of large-scale heat shrink tubing positioning and installation processes.

Detailed Implementation

[0041] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0042] like Figure 1 and Figure 2As shown, the cable heat shrink tubing position adjustment device of this embodiment includes: a base 100 with a translation guide rail 110; a lifting mechanism 200 slidably connected to the translation guide rail 110, including a translation slider 210, and a power drive component 220 and a lifting guide rail 230 fixedly mounted on the translation slider 210; an axial translation mechanism 300 including a linear displacement component 310 arranged parallel to the translation guide rail 110, a push plate 320 provided on the linear displacement component 310, and the push plate 320 fixedly connected to the translation slider 210; a rotary drive mechanism 400 slidably connected to the lifting guide rail 230, including a rotary drive component 410, a connecting plate 420 and a rotating part 430, the connecting plate 420 being fixedly connected to the power drive component 220; and a clamping and positioning component 500 fixed to the rotating part 430 by a mounting bracket 510, the clamping and positioning component 500 being coaxially arranged with the rotary drive mechanism 400. The term "coaxial" here should be understood as the same axis of rotation, often referring to two or more components sharing the same central axis. In this application, the clamping and positioning assembly 500 and the rotating part 430 of the rotary drive mechanism 400 should have the same axis of rotation. That is, when the rotary drive mechanism 400 is working, the clamping and positioning assembly 500 will rotate around the same axis, so that their movement trajectories are consistent and there will be no eccentricity or offset. "Coaxial setting" can ensure the synchronization and accuracy of rotational movement, while making the device structure of this application more compact and its operation more stable.

[0043] See Figure 3 In the above embodiment, the clamping and positioning component 500 includes: a clamping base 520 with at least two guide grooves 521; at least two movable grippers 530, each movable gripper 530 slidingly engaging with the guide groove 521 via a slider 531 at its end, and a sensor 550 on the side wall of the movable gripper 530 for detecting the position of the heat shrink tubing; and a gripper driving mechanism 540, disposed on the side wall of the clamping base 520 and connected to each movable gripper 530 via a linkage component, for driving the movable grippers 530 to move along the guide grooves 521. The movable grippers 530 slide in the guide grooves 521 via the sliders 531, allowing them to move only in a straight line or curve along a preset trajectory. Since heat shrink tubing clamping requires ensuring strict symmetry in the movement trajectories of each gripper, the guide grooves 521, through mechanical hard limiting, improve the clamping accuracy of the movable grippers 530 to a certain extent.

[0044] To make the technical solutions of the above embodiments clearer and more explicit, the operation process of this device will now be described technically in conjunction with the accompanying drawings and specific embodiments:

[0045] 1. Initial position state (as shown in the attached document) Figure 4 (as shown)

[0046] The clamping and positioning component 500 is at the initial coordinate point (X0, Y0, Z0). Through the fully retracted state of the piston rod of the lifting guide rail 230 and the power drive component 220, the clamping and positioning component 500 maintains its position at the first vertical height H1. At this time, the clamping and positioning component 500 is in a relatively high horizontal stroke position, reserving working space for the wire feeding process and avoiding interference with the previous process. Figure 4 In the previous process, the cable clamp has fixed the cable. The clamp is located directly below the clamping and positioning component 500, providing a basis for the heat shrink tubing clamping operation of the clamping and positioning component.

[0047] The rotating part 430 of the rotary drive mechanism 400 is in a zero-degree angle reference position, so that the clamping center axis of the mounting bracket 510 is parallel to the cable conveying direction.

[0048] 2. Axial positioning stage:

[0049] The power drive component 220 drives the piston rod to extend, causing the connecting plate 420 to descend vertically along the lifting guide rail 230 to the second vertical height position H2; the axial translation mechanism 300 causes the rotary drive mechanism 400 to move axially, driving the clamping and positioning component 500 to move. The axial position of the heat shrink tube is determined by the sensor 550 along the way, until the clamping and positioning component 500 moves to the far end of the heat shrink tube.

[0050] 3. Angle correction stage (as shown in the attached document) Figure 5 (as shown)

[0051] The rotation drive assembly 410 drives the rotating part 430 to deflect within a range of ±90° around the axis (Y-axis), so that the sensor 550 measures the position of the heat shrink tubing within a range of 180° and obtains the actual tilt angle θ of the heat shrink tubing; the rotating part 430 rotates to compensate for the angle θ according to the value of θ.

[0052] 4. Clamping and resetting stage (as shown in the attached diagram) Figure 6 (as shown)

[0053] The gripper drive mechanism 540 pushes the movable gripper 530 to close synchronously along the guide groove 521 through the linkage component to clamp the heat shrink tubing; the rotary drive component 410 drives the rotating part 430 to rotate to the zero-degree angle reference position, while the axial translation mechanism 300 pulls the clamping and positioning component 500 to move axially until the near end face of the heat shrink tubing abuts against the preset installation end face of the cable.

[0054] 5. Reset and release phase:

[0055] The gripper drive mechanism 540 pulls the movable gripper 530 back to the initial open position along the guide groove 521 through the linkage component; the power drive component 220 and the rotary drive mechanism 400 work together to make the clamping and positioning component 500 rise to H1 along the lifting guide rail 230 and reset to the initial coordinate point (X0,Y0,Z0) along the axis.

[0056] The above description of the actual operation of the apparatus of this application should be understood as not being the only one, and this application can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments of apparatus operation are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0057] See Figure 3 In some embodiments, at least two lateral stabilizing jaws 560 are also included. These lateral stabilizing jaws are connected to the movable jaw via a pivot, and the lateral stabilizing jaws 560 and the movable jaw 530 are arranged parallel to each other along the axial direction. By providing the lateral stabilizing jaws 560, the movable jaw 530 is assisted in clamping the cable, ensuring the cable is horizontal and straight. The lateral stabilizing jaws are connected to the movable jaw via a pivot, which is fixed to the movable jaw. The lateral stabilizing jaws can rotate around the pivot relative to the movable jaw. The lateral stabilizing jaws 560 and the movable jaw 530 cooperate to form a distributed support structure. Through synchronized movement with the movable jaw 530, they provide lateral constraint force during cable clamping, effectively suppressing workpiece displacement within the clamping plane. This auxiliary support is particularly advantageous when the workpiece end length exceeds the effective clamping range of the movable jaw 530 or when the clamping force of the movable jaw 530 is insufficient.

[0058] It should be noted that in some embodiments, the lateral stabilizing gripper 560 can also be set independently, forming a spatially decoupled layout with the movable gripper 530, abandoning the traditional linkage constraint, and can independently perform radial clamping compensation. The lateral stabilizing gripper 560 has an independent slider groove system, which is particularly important when handling workpieces of different shapes or sizes, such as asymmetrical cables or heat shrink tubing, and can adaptively adjust to achieve dynamic balance of local clamping forces.

[0059] In some embodiments, the clamping end of the movable jaw 530 is provided with a V-shaped, U-shaped, or arc-shaped clamping groove 532, and the inner surface of the clamping groove 532 is provided with anti-slip texture in the form of a serrated pattern or an array of raised dots. Among them, the symmetrical inclined surface of the V-shaped clamping groove 532 forms a self-centering effect through geometric constraints, and has a wedge effect. When clamping cables of different diameters, the two inclined surfaces generate normal component forces, forcing the cable axis to coincide with the center line of the jaw. The curvature of the groove surface of the U-shaped clamping groove 532 is more matched with the outer edge of the heat shrink tubing, forming a continuous envelope contact surface, which can reduce the contact pressure, effectively protect the heat shrink tubing, and make the clamping force more uniform. The arc-shaped clamping groove 532 has a larger contact surface for clamping cylindrical heat shrink tubing, and better anti-torsion performance, which improves the stability of clamping to a certain extent. Furthermore, when the clamping end face of the clamping groove 532 is serrated, it can provide a directional locking function (resisting axial movement); if the clamping end face of the clamping groove 532 is provided with an anti-slip texture of a convex array, it can suppress radial rotation when clamping heat shrink tubing, further improving the stability and reliability of clamping. Of course, in some other embodiments, the clamping groove 532 of the movable jaw 530 can also be set separately to form a replaceable clamping module, which is connected to the movable jaw 530 body through a quick-change interface, making it easy to switch the corresponding clamping groove 532 type when facing heat shrink tubing of different specifications and properties, so as to achieve better clamping performance and further solve the problems of poor clamping adaptability, high local damage rate and insufficient dynamic stability of traditional jaws.

[0060] In other embodiments, the clamping groove 532 may also adopt a composite groove structure, that is, the clamping groove 532 is axially segmented with a V-shaped guide section and a U-shaped stabilizing section to realize a two-stage clamping strategy of "centering first and then locking", which improves the clamping accuracy and can also appropriately increase the angle fault tolerance, and has better clamping stability.

[0061] See Figure 3In some embodiments, a limiting baffle is provided at the distal end of the clamping groove 532. The limiting baffle can be part of the movable gripper 530 body; or it can be a component relatively independent of the movable gripper 530 body, which is fixedly or detachably connected to the movable gripper 530 body. Specifically, as a limiting baffle part of the movable gripper 530 body, the clamping groove 532 can be obtained by slotting through a proximal end face of the movable gripper 530 to the distal end face. At a certain part of the clamping groove 532, a plate-like structure protrudes from the movable gripper 530, and this plate-like structure is the limiting baffle; of course, the clamping groove 532 can also be formed by slotting a certain distance from the proximal end face, without needing to penetrate to the distal end face of the movable gripper 530. In this case, the distal side of the clamping groove 532 is part of the movable gripper 530 body, which is the limiting baffle. In practical industrial applications, heat shrink tubing, which is the object being clamped, may have different specifications and models. In order to make the range of adaptation wider, the limiting baffle is detachably connected to the movable jaw 530 body, and the matching limiting baffle can be flexibly replaced, thus improving the compatibility of this device.

[0062] See Figure 3 In some embodiments, the number of movable grippers 530 is two and they are arranged opposite each other, and the guide grooves 521 are two sets of parallel guide grooves 521. The two sets of guide grooves 521 are strictly parallel, forming a double linear guide rail system, which restricts the movable grippers 530 to move only along a single degree of freedom, making it easier to eliminate motion errors at other angles. The two movable grippers 530 achieve closed-loop synchronous drive through the linkage component, resulting in smaller displacement synchronization errors and ensuring that the center of the workpiece always coincides with the clamping axis, thus achieving higher clamping accuracy. The aforementioned linkage component is driven by a gripper drive mechanism 540; the gripper drive mechanism 540 can be composed of a stepper motor and a ball screw, and of course, the stepper motor can also be replaced by a servo motor; in addition, a linear motor and a double cylinder can also be used to form a gripper drive mechanism 540. It is conceivable that, in addition to the above structure, the gripper drive mechanism 540 can also be other combined structures that can provide driving force, and the linkage component cooperates with the gripper drive mechanism 540 to transmit torque. Its specific structure will not be described in detail here.

[0063] See Figure 3In the previous embodiment, the two movable grippers have a single degree of freedom of movement relative to the guide groove. Frequent reciprocating motion can easily cause the grippers to deviate, resulting in a lack of precise alignment and hindering the achievement of long-term, stable, high-precision clamping of the target. Therefore, this application presents another embodiment where a stabilizing guide rail 533 is fitted onto the slider and fixed to a mounting bracket or clamping seat. Due to the relative stability of the stabilizing guide rail 533, the slider fitted onto it maintains high-precision linearity even after multiple sliding operations, thus achieving high-quality and high-reliability clamping in mass production. As an extension, in addition to high-precision fitting, appropriately increasing lubrication can also significantly improve the sliding effect. For example, applying grease or lubricating oil to the stabilizing guide rail 533, or installing ball bearings on the slider or stabilizing guide rail 533, can all increase the reliability and durability of this application to a certain extent.

[0064] In some embodiments, a control module is also included, which is signal-connected to the lifting mechanism 200, the axial translation mechanism 300, the rotary drive mechanism 400, and the clamping and positioning component 500 to form a closed-loop control circuit. This embodiment, through closed-loop control architecture and multi-physics field collaborative optimization, overcomes the triangular contradiction of accuracy-speed-reliability to a certain extent, which is beneficial to improving the automation efficiency and accuracy of the device.

[0065] In some embodiments, a pressure sensor is provided at the clamping end of the movable gripper 530, and the pressure sensor is signal-connected to the control module. The pressure sensor (such as a piezoelectric, strain gauge, or MEMS type) is embedded in the clamping working surface and can measure the contact pressure in real time. The control module can adjust the gripper displacement or torque output of the gripper drive mechanism 540 according to the measured value, thereby significantly improving the clamping accuracy and avoiding damage to the workpiece or gripper. The control module can pre-store multiple clamping modes (such as rigid clamping, flexible envelope, and constant force clamping) and automatically switch according to sensor data to meet the operational requirements of workpieces of different specifications.

[0066] In some embodiments, the movable gripper 530 includes: a base, the end of which is rigidly connected to the slider 531; a clamping block, detachably mounted on the end of the base; and a pre-tensioning spring member, with its two ends connected to the base and the clamping block respectively. The pre-tensioning spring member is provided with adjusting bolts, which are used to adjust the relative distance between the base and the clamping block. The rigid connection between the end of the base and the slider 531 improves the clamping accuracy and the overall integrity of the device. Specifically, the base can be a metal matrix, a ceramic matrix, or other composite material matrix. Metal matrices offer better rigidity and strength, ceramic matrices have better high-temperature resistance and corrosion resistance, while metal-based composite material matrices have strong wear resistance and high-temperature resistance. A more suitable matrix can be flexibly selected according to different application scenarios. The detachable structure of the clamping block facilitates the replacement of clamping blocks of different shapes or materials to adapt to different workpiece requirements, increasing the versatility of the device. Simultaneously, the detachable structure also facilitates maintenance and replacement of worn parts, reducing maintenance costs and time. Furthermore, the clamping block and the base are elastically connected via a pre-tensioning elastic element, which makes the clamping process more flexible and precise, adapting to the clamping requirements of different workpieces and avoiding over-tightening or over-loosening. The pre-tensioning elastic element can be a pre-tensioning spring, a pre-tensioning leaf spring, or a pre-tensioning hydraulic component; any element with a certain degree of toughness and adjustable extension / retraction is acceptable. The adjusting bolt has a simple, reliable mechanical structure and is easy to operate, allowing for quick adjustment of the stress in the pre-tensioning elastic element on-site, thus improving the actual clamping effect.

[0067] In some embodiments, the lateral stabilizing gripper 560 further includes: a fine-adjusting elastic element, one end of which is connected to the lateral stabilizing gripper and the other end to the movable gripper; and a limiting protrusion that protrudes toward the limiting portion of the movable gripper to limit the rotation angle range of the lateral stabilizing gripper. In this embodiment, the limiting portion can be a through hole or a groove on the movable gripper. The through hole can be cylindrical or an irregular arc-shaped hole; the groove can be rectangular or arc-shaped, and there is no single limitation. Any structural form capable of accommodating the movement of the limiting protrusion within its constrained space can be considered a limiting portion. After setting the initial length of the fine-adjusting elastic element with the fine-adjusting bolt, it provides elastic clamping force for the lateral stabilizing gripper 560 to clamp the heat shrink tubing, allowing it to spring back to its initial position when the lateral stabilizing gripper 560 is not clamping the heat shrink tubing.

[0068] It should also be noted that, in addition to the lateral stabilizing gripper 560 that shares the same drive source as the movable gripper 530, an independently driven lateral stabilizing gripper 560 can also be provided. This lateral stabilizing gripper 560 is directly controlled by another drive source and can provide a clamping force equal to or different from that of the movable gripper 530. In this way, by independently controlling the torque output ratio of the two drive sources, the clamping stiffness can be adjusted by changing the diameter, which is especially suitable for clamping irregularly shaped parts and expands the applicability of this device.

[0069] In some embodiments, the power drive is an electric cylinder assembly, which includes a cylinder and a solenoid valve for controlling the extension and retraction of the cylinder. It is conceivable that the power drive could also be a hydraulic motor or a pneumatic motor; that is, the broad scope of power drives should include all components capable of providing linear driving force. Since the power drive is designed to support and drive the rotary drive mechanism to move longitudinally, the combination of a cylinder and a solenoid valve offers good adaptability and economy, while also providing relatively high mobility.

[0070] In addition, linear displacement components include ball screws and drive motors. The combination of ball screws and drive motors is very common, has good economic efficiency, and can also balance stability and reliability to a certain extent. Of course, linear displacement components can also be linear motors, telescopic hydraulic cylinders, or telescopic pneumatic cylinders, depending on the required work accuracy and efficiency.

[0071] In some embodiments, the rotary drive component is a servo motor or a stepper motor. Any energy component that provides energy to generate rotational kinetic energy in the rotating part can be used as a rotary drive component. Servo motors and stepper motors are currently relatively mature technologies with reliable performance. Selecting appropriate specifications and models can meet accuracy requirements and reduce economic costs to some extent.

[0072] In this application, unless otherwise specified, technical terms such as "axis," "axis line," and "axis center" are closely related to the rotation axis of the movable gripper 530, and those skilled in the art should not interpret them in any other way that would violate the technical essence of this application. Similar parts between the embodiments provided in this application can be referred to mutually. The specific embodiments provided above are merely several examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other embodiments extended from the scheme of this application without creative effort are within the scope of protection of this application.
