Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness assembly and production technology, and in particular to a sleeve device, sleeve equipment and wire harness assembly line based on multi-core synchronous sleeve. Background Technology
[0002] In wire harness assembly production, after the wire harness undergoes stripping and shielding separation processes, the exposed wire cores need to be fitted with heat shrink tubing and crimped with terminals. Traditional manual tubing methods have significant efficiency bottlenecks. Operators must individually attach heat shrink tubing to each wire core, which is not only time-consuming and labor-intensive but also prone to quality issues such as mismatched tubing numbers with wire core models. Although some automated tubing equipment exists on the market, these devices typically only perform tubing operations on single wire cores. Because the stripped wire cores are often scattered, existing equipment cannot simultaneously tubing multiple cores, hindering overall production efficiency. Furthermore, during the tubing process, insufficient alignment accuracy between the heat shrink tubing and the wire core, as well as unstable tubing delivery, frequently affect tubing quality, further restricting the overall efficiency of the wire harness assembly line.

[0059] Reference Figures 1 to 5 This utility model provides a sleeve device 1, wherein the sleeve device 2 uses the sleeve device based on multi-core synchronous sleeve provided in this application.
[0060] Specifically, the sleeve device 2 includes a core 4 conveying module and a tube body conveying module. The core 4 conveying module includes a first clamping seat 100, which has multiple first clamping cavities arranged radially for fixing multiple cores 4 to be sleeved. The tube body conveying module is located at one end of the core 4 conveying module and includes a second clamping seat 200, which has multiple second clamping cavities 220 arranged radially for fixing a corresponding number of heat shrink tubing. The core 4 conveying module can move linearly to insert the cores 4 into the heat shrink tubing to complete the sleeve connection; alternatively, the second clamping seat 200 can move linearly to move the insulating tube 3 closer to the cores 4 to complete the sleeve connection.
[0061] It should be noted that during the process of connecting the insulating tube 3 and the wire core 4, the first clamping cavity and the second clamping cavity 220 always maintain a coaxial relationship.
[0062] Understandably, after the stripping of the wire core 4 is completed, the diverging wire cores 4 are placed into the radially arranged first clamping cavities. The tube delivery module loads the heat shrink tubing into the corresponding second clamping cavity 220, and ensures that each wire core 4 is in a straight line with the corresponding tube through position calibration. The drive mechanism pushes the wire core 4 delivery module to move towards the tube delivery module, so that multiple wire cores 4 are simultaneously inserted into the corresponding heat shrink tubing.
[0063] Alternatively, in some other embodiments, the drive mechanism pushes the second clamping seat 200 to move toward the wire core 4 conveying module, so that multiple wire cores 4 are simultaneously inserted into the corresponding insulating tubes 3.
[0064] Among them, the radially arranged clamping cavities form an array of workstations, which effectively utilize space to achieve multi-station parallel operation. The linear motion mechanism ensures the synchronization and consistency of batch sleeves, and achieves batch sleeves while avoiding manual handling of wire core 4, reducing the risk of model matching errors. It effectively solves the technical problem of synchronous sleeve of multiple wire core 4 and realizes the batch automated processing of unhandled wire core 4.
[0065] This application provides specific embodiments of the second clamping seat 200. For example... Figures 1 to 4 As shown, the second clamping seat 200 includes two clamping blocks 210 arranged opposite each other. The clamping blocks 210 are provided with arc-shaped grooves 211, and the two arc-shaped grooves 211 cooperate to form a second clamping cavity 220.
[0066] In some embodiments of this application, the two clamping blocks 210 can achieve relative displacement through a sliding track or hinge mechanism to adjust the clamping distance to accommodate insulating tubes 3 of different diameters. The arc-shaped groove 211 refers to the groove structure provided on the surface of the clamping block 210, which can specifically adopt a semi-circular or U-shaped cross section. After the grooves of the two clamping blocks 210 are aligned, they form a complete circular channel to wrap the circumferential surface of the heat shrink tubing and prevent it from radially shifting during the sleeve connection process.
[0067] Understandably, when the two clamping blocks 210 are in the closed state, they form a continuous cylindrical clamping cavity through the arc-shaped groove 211, confining the heat shrink tubing within the cavity and preventing radial movement. When it is necessary to release the heat shrink tubing, the two clamping blocks can separate horizontally, opening the clamping cavity. During the connection process, the clamping blocks remain closed, ensuring that the heat shrink tubing and the wire core 4 remain coaxial.
[0068] The relative movement of the clamping blocks 210 can be achieved through a linear guide or a rotating mechanism. For example, the clamping blocks 210 can move synchronously and symmetrically by setting a slider to cooperate with the guide. The depth of the arc-shaped groove 211 can be set to 1.1-1.3 times the radius of the insulating tube 3, which can completely wrap the tube body without hindering axial movement.
[0069] Beneficially, this application employs a detachable double-clamp design, forming a closed guide channel during the clamping phase and rapidly separating the clamps during the release phase. This ensures the stability of multi-tube clamping while improving operational efficiency. Furthermore, the rigid clamps in this design, in conjunction with the groove, provide uniform circumferential constraint force. Different tube specifications can be accommodated by adjusting the spacing of the clamping blocks 210. This application achieves synchronous and stable clamping of multiple heat shrink tubings, ensuring that the tubing and wire core 4 remain coaxially aligned during the sleeve process, while also solving the problem of heat shrink tubing easily shifting and falling off when sleeved with multiple wire cores 4.
[0070] According to some embodiments of this application, such as Figure 2As shown, the tube conveying module also includes a first driving member 300, one or both of the two clamping blocks 210 are connected to the first driving member 300, and the first driving member 300 can drive one of the clamping blocks 210 away from or closer to the other clamping block 210; the tube conveying module also includes a mounting bracket 400, the two clamping blocks 210 are mounted on the mounting bracket 400, one or both of the two clamping blocks 210 are slidably connected to the mounting bracket 400, and one of the two clamping blocks 210 can move away from or closer to the other clamping block 210.
[0071] Understandably, when it is necessary to clamp heat shrink tubing of different diameters, the first drive unit 300 is activated and pushes one of the clamping blocks 210 to move along the slide rail of the mounting bracket 400, so that the distance between the two clamping blocks 210 is automatically adjusted to match the outer diameter of the heat shrink tubing. During movement, the clamping blocks 210 are guided and constrained by the slide rail to prevent offset or wobbling, ensuring that the second clamping cavity 220 remains coaxial. After clamping is completed, the first drive unit 300 keeps the clamping blocks locked in position, forming a stable clamping force to prevent the heat shrink tubing from shifting during the tubing process.
[0072] Beneficially, this application achieves automated adjustment of the clamping spacing through the first driving component 300. Combined with the sliding guide structure of the mounting bracket 400, it not only improves the adaptability of the clamping mechanism but also eliminates errors caused by manual intervention. This ensures precise alignment of the heat shrink tubing and the wire core 4 during multi-core 4 synchronous sleeve application, solving the problems of the inability to automatically adjust the clamping spacing and insufficient stability of the clamping structure during heat shrink tubing clamping. It achieves rapid adaptation and reliable fixation of heat shrink tubing of different diameters, providing precise tube positioning guarantee for multi-core 4 synchronous sleeve application and effectively avoiding sleeve misalignment or detachment.
[0073] Specifically, the tube conveying module also includes a second driving component. The mounting bracket 400 is connected to the second driving component. The second driving component can drive the mounting bracket 400 to move linearly in the horizontal direction so that the first clamping cavity and the second clamping cavity 220 are coaxial.
[0074] Understandably, when the first clamping cavity and the second clamping cavity 220 experience axial misalignment due to assembly errors, the second driving component is activated, pushing the mounting bracket 400 to move horizontally. A linear guide rail on the mounting bracket 400 guides the movement path, causing the second clamping seat 200 to shift as a whole until the second clamping cavity 220 and the first clamping cavity are coaxial. This movement process receives real-time position information feedback through a displacement sensor or vision inspection system, forming a closed-loop control to ensure alignment accuracy.
[0075] Advantageously, this application achieves automated dynamic calibration of the clamping cavity position through the combination of a movable mounting bracket 400 and a drive component, eliminating accumulated assembly errors without disassembling the components.
[0076] According to some embodiments of this application, the tube conveying module further includes a tube feeding device, which is disposed at one end of the second clamping seat 200. The second clamping seat 200 can be away from or close to the tube feeding device. The tube feeding device is used to convey the tube to be sleeved into the second clamping cavity 220.
[0077] Specifically, the tube feeding device includes a feeding roller group 500 and a guide channel, such as... Figure 2 and Figure 5 As shown, the guide channel is located between the feeding roller group 500 and the second clamping seat 200.
[0078] The ability of the second clamping seat 200 to move away from or near the tube feeding device means that the clamping seat has a horizontal movement function, which can be achieved by a combination of linear guide rail and drive cylinder. That is, when the tube is being sleeved, it moves away from the feeding device. After the first clamping cavity and the second clamping cavity 220 are aligned, the second clamping seat 200 moves toward the wire core 4 conveying module to complete the tube sleeving process. During the feeding stage of the insulating tube 3, the second clamping seat 200 moves closer to the feeding device to shorten the tube conveying path and prevent the insulating tube 3 from falling off after entering the second clamping cavity 220 due to its long length.
[0079] Furthermore, the guide channel guides the tube body along a preset path to the vicinity of the second clamping seat 200. When the second clamping seat 200 moves to a position close to the tube body feeding device via the driving component, the tube body is pushed and inserted into the second clamping cavity 220 from the end of the guide channel. After the clamping block 210 closes and fixes the tube body, the second clamping seat 200 carries the tube body to a position aligned with the wire core 4 conveying module. At this time, the wire core 4 conveying module pushes the wire core 4 into the tube body to complete the sleeve connection. Alternatively, after the second clamping seat 200 carries the tube body to a position aligned with the wire core 4 conveying module, it continues to move towards the wire core 4 conveying module to complete the sleeve connection. During this process, multiple tube bodies are synchronously conveyed through parallel guide channels, realizing the batch sleeve connection of multiple wire cores 4 with corresponding tube bodies.
[0080] Beneficially, this application utilizes parallel guide channels in conjunction with a movable second clamping seat 200 to enable multiple tubes to be linearly conveyed within independent channels, avoiding mutual interference. The horizontal movement function of the second clamping seat 200 ensures both the shortest tube conveying path during the feeding stage and precise alignment of the clamping cavity with the wire core 4 during the sleeve stage. This resolves the contradiction between synchronous conveying of multiple tubes and precise positioning, achieving automated synchronous feeding of multiple heat shrinkable tubes and eliminating efficiency bottlenecks and model matching errors caused by manual operation. The linear conveying of the tubes within independent guide channels, combined with the movement control of the clamping seats, ensures that the tube axis and the clamping cavity remain coaxial, guaranteeing accurate alignment of multiple tubes with the corresponding wire core 4 during the sleeve process. This achieves precise positioning of multiple heat shrinkable tubes along the conveying path, ensuring that each heat shrinkable tube remains coaxially aligned with its corresponding wire core 4, preventing sleeve failure due to tube misalignment. Simultaneously, the cooperation between the guide channels and the feeding roller group 500 reduces the need for manual intervention, improving the production efficiency and yield of synchronous sleeved multiple wire cores 4.
[0081] In other embodiments of this application, such as Figure 3 As shown, the feed end of the feeding roller assembly 500 is also equipped with a guide channel.
[0082] Understandably, the heat shrink tubing enters the guide channel directly after being output from the roller assembly. The constraint of the channel's inner wall maintains its linear trajectory until it enters the second clamping cavity 220. When the heat shrink tubing is long, guide channels can be simultaneously installed at both the inlet and outlet ends to form a segmented guide structure, preventing the tubing from sagging due to its own weight or external interference, thus avoiding path deviation.
[0083] Beneficially, this application adds multi-position guide channels to form segmented path constraints, providing continuous guidance at key nodes before the heat shrink tubing enters the feeding roller group 500, during the conveying process, and before entering the clamping cavity. This eliminates potential offset risks at each stage, achieving precise positioning of multiple heat shrink tubings on the conveying path and ensuring that each heat shrink tubing remains coaxially aligned with its corresponding wire core 4, avoiding fitting failures due to tubing misalignment. At the same time, the cooperation between the guide channels and the feeding roller group 500 reduces the need for manual intervention, improving the production efficiency and yield of synchronous tubing for multiple wire cores 4.
[0084] Specifically, such as Figure 3 As shown, the guide channel includes a first guide seat 600 and a second guide seat 700.
[0085] According to some embodiments of this application, a first guide seat 600 is disposed at the feed end of the feeding roller assembly 500. The first guide seat 600 is provided with a first guide channel 610 through which heat shrink tubing can pass, and a plurality of first guide channels 610 are arranged along the radial direction of the first guide seat 600. A second guide seat 700 is disposed between the feeding roller assembly 500 and the second clamping seat 200. The second guide seat 700 is provided with a second guide channel 710 through which heat shrink tubing can pass, and a plurality of second guide channels 710 are arranged along the radial direction of the second guide seat 700.
[0086] Understandably, before the heat shrink tubing enters the feeding roller assembly 500 from the storage device, it is initially positioned by multiple first guide channels 610 of the first guide seat 600. Each first guide channel 610 constrains the movement path of a single tube, preventing multiple tubes from crossing and tangling when entering the feeding roller assembly 500. After being conveyed by the feeding roller assembly 500, the heat shrink tubing enters the second guide channel 710 of the second guide seat 700 for secondary positioning. The radially arranged guide channels correct the offset generated by the tube during conveying. The first guide seat 600 and the second guide seat 700 work together to form a progressive positioning system. The first guide channel 610 eliminates the initial scattered state, and the second guide channel 710 compensates for the conveying path deviation, ultimately ensuring that multiple heat shrink tubing are precisely aligned with their corresponding clamping cavities.
[0087] Beneficially, this application employs a layered guiding design, setting radially arranged guiding channels at the feeding end and conveying section respectively. This solves the initial positioning problem of parallel multi-tube conveying and overcomes the cumulative error caused by long-distance conveying through a secondary correction mechanism. In particular, the radial arrangement matches the distribution pattern of the clamping cavities, ensuring that each tube maintains a spatial correspondence with the target clamping cavity throughout the conveying process. This achieves synchronous and precise positioning and conveying of multiple heat shrink tubings, effectively preventing tube misalignment or entanglement during conveying. The first guiding channel 610 standardizes the tube arrangement from the source, while the second guiding channel 710 performs position correction at key nodes. This dual guarantee mechanism ensures that multiple heat shrink tubings accurately correspond to the positional requirements of the clamping cavity of the wire core 4, solving the problem of misalignment between the heat shrink tubing and the wire core 4 caused by insufficient guidance in traditional equipment, and significantly improving the efficiency and accuracy of tubing operations.
[0088] According to some embodiments of this application, such as Figure 1 As shown, the sleeve device 2 of this application is also provided with a translation module 800. Specifically, the mounting bracket 400 is connected to the translation module 800, and the translation module 800 can drive the second clamping seat 200 to move linearly between the second guide seat 700 and the wire core 4 conveying module.
[0089] Understandably, the translation module 800 drives the mounting bracket 400 to move along a predetermined track, causing the second clamping seat 200 to switch positions between the second guide seat 700 and the wire core 4 conveying module. When heat shrink tubing needs to be loaded, the second clamping seat 200 is moved to the discharge end of the second guide seat 700, and the heat shrink tubing enters the second clamping cavity 220 through the second guide channel 710. After the tubing is loaded, the translation module 800 moves the second clamping seat 200 to a position coaxial with the wire core 4 conveying module. At this time, the wire core 4 conveying module drives the first clamping seat 100 to approach the second clamping seat 200, so that the wire core 4 and the heat shrink tubing are fitted together. Alternatively, the translation module 800 continues to move the second clamping seat 200, so that the wire core 4 and the heat shrink tubing are fitted together. By integrating the translation module 800, the clamping seat automatically switches between the tube receiving station and the sleeve station, eliminating timing errors caused by multi-device collaborative operation. At the same time, it reduces the number of drive units and realizes the automated connection between heat shrink tubing feeding and wire core 4 sleeve process. It ensures the axial alignment accuracy of the tube and wire core 4 when multiple wire cores 4 are working synchronously, avoids sleeve failure caused by clamping seat position deviation, and significantly improves the yield and production efficiency of multi-wire core 4 synchronous sleeve.
[0090] As a further optimization of the solution, the feeding ends of the second clamping cavity 220, the first guide channel 610, and the second guide channel 710 are all equipped with guide structures.
[0091] It is understood that the guiding structure refers to the physical structure used to guide the tube body to move along a preset path. Specifically, it can be implemented using a tapered flared structure, with the larger end of the tapered flared opening facing outwards to increase the tolerance range when the tube body enters the channel. The guiding structure of the second clamping cavity 220 is configured to eliminate radial offset when the tube body enters the clamping station, which can be implemented using a chamfered transition structure, with the chamfered surface forming an angle with the tube body axis to guide the tube body into the clamping cavity. The guiding structure of the first guiding channel 610 is configured to provide initial guidance for the multiple tube bodies output from the feeding roller group 500.
[0092] That is, when the heat shrink tubing is output from the feeding roller group 500, the tapered flaring structure at the entrance of the first guide channel 610 guides multiple tubes into their respective first guide channels 610, preventing the tubes from crossing and tangling in the initial stage. Similarly, when the tubes enter the second guide channel 710, the tapered flaring structure at the entrance of the second guide channel 710 guides multiple tubes into their respective second guide channels 710. Finally, when the tubes reach the entrance of the second clamping cavity 220, the chamfered transition structure precisely guides the end of the tube to the center position of the clamping cavity, at which point the clamping mechanism closes and completes the positioning. The three-stage guiding structure forms continuous position correction in the feeding, conveying, and clamping stages, ensuring that multiple heat shrink tubings remain strictly coaxial with their corresponding cores 4. This achieves full-process trajectory control of multiple heat shrink tubings from feeding to clamping, eliminating axial offset caused by tube bending and conveying vibration. The tube is always under control during transportation, which avoids tube misalignment or tube jamming caused by positional deviation, and ensures accurate alignment of the wire core 4 and the heat shrink tubing in subsequent tubing processes.
[0093] According to some embodiments of this application, such as Figure 1 As shown, the sleeve device 2 is also equipped with a tube cutting module 900 to achieve fixed-length cutting of the insulating tube 3.
[0094] Specifically, the tube cutting module 900 is located at the discharge end of the feeding roller group 500, wherein the tube cutting module is either a cutting blade or a laser cutting device.
[0095] Understandably, after the heat shrink tubing is continuously conveyed to the discharge end by the feeding roller group 500, the tubing cutting module 900 triggers the cutting action according to the preset length parameters. When a cutting blade is used, the blade moves perpendicular to the tubing conveying direction under the drive of a servo motor, completing a mechanical cut; when a laser cutting device is used, the laser beam forms a heat-affected zone on the tubing surface, achieving non-contact cutting through energy focusing. Both methods use a closed-loop control system to ensure that the cutting length is consistent with the preset value, avoiding dimensional deviations caused by manual operation. The cut heat shrink tubing is transferred to the second clamping cavity 220, where it is synchronously connected with the wire core 4 conveying module to complete the sleeve connection, solving the problems of low efficiency and insufficient precision in fixed-length cutting of heat shrink tubing, and achieving precise control of the tubing length during the synchronous sleeve connection of multiple wire cores 4. The coordinated work of the cutting module and the feeding roller group 500 improves the processing cycle, and the flexible selection of the two cutting methods can adapt to the processing needs of heat shrink tubing of different materials and diameters, ensuring a flat and deformation-free cut surface.
[0096] Beneficially, this application achieves precise, fixed-length cutting of heat shrink tubing by integrating an automated cutting module and combining it with the continuous conveying function of the 500 feeding roller group. The configuration of the cutting blade and laser cutting device maintains the high reliability of the mechanical structure while reducing physical damage to the tubing surface through non-contact cutting.
[0097] According to some embodiments of this application, the bushing device 2 of this application is further provided with an identification module. Specifically, the identification module includes a first detector and a second detector, wherein the first detector is used to acquire marking information on the surface of the insulating tube 3, and the second detector is used to acquire color information of the wire core 4 to be bushed.
[0098] Understandably, the first detector refers to a device used to read the markings on the surface of the insulating tube 3. This can be implemented using a visual sensor or a QR code scanner. By identifying the markings on the surface of the insulating tube 3, such as the model code, it ensures that the sleeve and the core 4 match in specifications. The second detector refers to a device used to identify the color of the core 4. This can be implemented using a spectral analysis sensor or an RGB color sensor. By detecting the color characteristics of the core 4's outer sheath, such as red, blue, or yellow, it determines the functional classification of the core 4.
[0099] Specifically, during the sleeve connection process, the first detector scans the pre-printed markings on the surface of the insulating tube 3, for example, by capturing the marking pattern through an image acquisition unit and transmitting the data to the control system for analysis. Simultaneously, the second detector identifies the color of the outer sheath of the wire core 4, for example, by emitting a specific wavelength light source and receiving the reflected spectrum to determine the color parameters. Based on the correspondence between the marking information and the color information, the control system automatically matches the insulating tube 3 and the wire core 4, driving the wire core 4 conveying module and the tube conveying module to complete the sleeve connection operation. When a mismatch between the marking and color information is detected, the system triggers an alarm and suspends the operation.
[0100] Beneficially, this application achieves automated matching and verification through dual detector collaborative identification, avoiding the problem of mismatch between the sleeve and the core 4 due to human error. By automatically verifying the correspondence between the insulating tube 3 and the core 4, the accuracy of the sleeve operation is ensured, while reducing manual intervention and improving the production efficiency and quality consistency of multi-core 4 synchronous sleeves.
[0101] According to some embodiments of this application, such as Figure 6 and Figure 7 As shown, the first clamping seat 100 is provided with a clamping mechanism. Specifically, the clamping mechanism includes a left clamping block 110 and a right clamping block 120, which are arranged opposite to each other to form a first clamping cavity.
[0102] In some embodiments of this application, the right clamping block 120 is hinged to the first clamping seat 100, and the left clamping block 110 is fixedly connected to the first clamping seat 100. The right clamping block 120 and the first clamping seat 100 are hinged via a hinge structure. Specifically, the hinge structure includes a hinge hole on the right clamping block 120 and a hinge shaft on the first clamping seat 100. Further, a hinge spring is provided between the hinge hole and the hinge shaft. It can be understood that the hinge spring in this application refers to a rotational elastic element installed inside the hinge pair, specifically a torsion spring or a coil spring. It is sleeved on the hinge shaft and forms a torque transmission relationship with the hinge hole, generating a rotational torque that causes the clamping block to close through elastic deformation. That is, when the right clamping block 120 rotates around the hinge shaft, it forces the hinge spring to undergo torsional deformation, and the reverse torque generated by the spring causes the right clamping block 120 to automatically return to the closed position without external force.
[0103] Alternatively, in another embodiment of this application, a telescopic member 130 is provided between the right clamping block 120 and the first clamping seat 100. It can be understood that the telescopic member 130 in this application refers to an elastic element with axial telescopic function, specifically implemented as a spring or pneumatic telescopic rod, with its two ends connected to the movable clamping block and the fixed component respectively, generating a continuous retraction force through elastic deformation. That is, when the right clamping block 120 is opened by an external force, the telescopic member 130 undergoes tensile deformation, storing elastic potential energy; after the external force disappears, the elastic restoring force drives the right clamping block 120 to reset towards the left clamping block 110, thereby maintaining the continuous clamping pressure of the first clamping cavity on the wire core 4.
[0104] Preferably, the retractable component 130 of this application is a spring, specifically a helical spring or a disc spring. The spring generates an elastic restoring force through compression or stretching, so that the right clamp 120 has the tendency to automatically adapt to changes in the size of the wire core 4.
[0105] According to some embodiments of this application, the second clamping seat 200 has a built-in heating component for fixing the insulating tube 3 to the wire core 4.
[0106] Alternatively, in some other embodiments, the second clamp 200 is connected to a heating device to fix the insulating tube 3 to the wire core 4.
[0107] It is understandable that after the insulating tube 3 and the wire core 4 are connected, heating can be performed directly to make the insulating tube 3 tightly wrap the wire core 4, without the need to transfer the wire core 4, thus simplifying the process.
[0108] Preferably, the second clamping seat 200 of this application has a built-in heating component. Optionally, the second clamping seat 200 is embedded with a ceramic heating element, which is heated in situ after being sleeved to ensure that the insulating tube 3 shrinks evenly and avoids local bubbles.
[0109] The advantage of this application is that by integrating the sleeve and heating process, the process chain is shortened, the bonding strength is improved, and the tube body of the wire core 4 after sleeve is prevented from falling off during the switching of work stations.
[0110] This application also provides a sleeve device 1 that utilizes the aforementioned sleeve device 2. Two sleeve devices 2 are arranged horizontally at intervals, allowing for simultaneous sleeve application of the cores 4 at both ends of the same wire harness, thereby effectively improving efficiency. Alternatively, cores 4 can be sleeved simultaneously on two independent wire harnesses, further enhancing efficiency.
[0111] Among them, such as Figure 1 As shown, two sleeve devices 2 are horizontally spaced to simultaneously sleeve the wire cores 4 at both ends of the same wire harness. In the practical application of this application, the mounting brackets 400 of both sleeve devices 2 are fixed on the mounting support 810, wherein the mounting support 810 is fixed on the translation module 800. It can be understood that the translation module 800 can simultaneously drive the two second clamping seats 200 to move synchronously, which helps to reduce equipment costs.
[0112] Furthermore, this application also provides a wire harness assembly device that uses the aforementioned sleeve device 2, or a sleeve device 1 having the aforementioned sleeve device 2.
