Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, specifically to a wire harness tape winding machine. Background Technology

[0002] Wire harnesses are critical components in electronic and electrical systems used to connect various parts, and are widely used in home appliances, automobiles, communication equipment, aerospace, and other fields. During wire harness manufacturing, the wrapping of tape around the wire harness surface (i.e., wire harness covering and shaping) is an important process. Currently, the wire harness wrapping process is mainly done manually, typically by workers holding the tape and wrapping it around the designated position of the wire harness, with simple tooling assisting in positioning. This traditional process has the following shortcomings: 1. High labor intensity and low efficiency: The wire harnesses need to be wound and fixed manually one by one, and more than 95% of the wrapping and shaping process relies on manual labor. Long hours of repetitive operation not only result in low efficiency and limited output, but also lead to worker fatigue.

[0003] 2. Poor quality consistency: The quality of manual wrapping depends on the worker's experience and condition. Prolonged operation can easily lead to visual fatigue, resulting in inconsistent tape tightness, positional deviations, and other quality problems. Differences in techniques between different workers can also cause inconsistencies in finished products, affecting product reliability.

[0004] 3. Limitations of manual inspection: In the traditional method, the quality after winding is mainly determined by manual visual inspection, which is easily affected by subjective human factors and makes it difficult to detect defects such as incomplete winding or loose winding in a timely manner.

[0005] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a winding machine for wire harness tape.

[0007] To achieve the above objectives, the specific solution of this utility model is as follows: This utility model provides a wire harness tape wrapping machine, comprising: CCD module, wire harness clamping mechanism, wire harness fixing module, tape wrapping mechanism; The wire harness clamping mechanism includes: a wire harness head end clamping mechanism and a wire harness tail end clamping mechanism; The wire harness fixing module includes: a wire harness head end fixing module and a wire harness tail end fixing module; The wire harness tail clamping mechanism, wire harness tail fixing module, adhesive tape wrapping mechanism, wire harness head fixing module, and wire harness head clamping mechanism are arranged sequentially from left to right. The wire harness head end fixing module and the wire harness tail end fixing module are respectively mounted on two X-axis moving mechanisms, and the head end and tail end of the wire harness are clamped by a gripper cylinder; Both the head end clamping mechanism and the tail end clamping mechanism of the wire harness are equipped with pressure sensors to detect the clamping status of the wire harness. The tape wrapping mechanism includes a rotating base and two sets of tape wrapping mechanisms disposed on the rotating base; The CCD module is used for size detection and positioning before and after the tape is wrapped.

[0008] Furthermore, each set of the tape wrapping mechanism includes a Y-axis assembly, a Z-axis assembly, a tape fixing and rotating shaft assembly, and a cutting and smoothing module; The Y-axis assembly is mounted on the Z-axis assembly, the tape-fixed rotating shaft assembly is mounted on the Y-axis assembly, and the cutting and smoothing module is mounted on the tape-fixed rotating shaft assembly.

[0009] Furthermore, the Y-axis assembly and Z-axis assembly are arranged perpendicularly to each other, and are used to drive the tape fixing rotation axis assembly to move in the vertical and horizontal directions to adjust the winding position of the tape.

[0010] Furthermore, the adhesive tape fixing rotating shaft assembly includes: a first motor, a driving wheel, a driven wheel, and an open gear; A drive wheel is installed on the output shaft of the first motor. The drive wheel meshes with two driven wheels. The two driven wheels mesh with an open gear. The tape is installed on the open gear. Driven by the first motor, the open gear drives the tape to rotate and wrap around the wire harness.

[0011] Furthermore, the wire harness head end fixing module and the wire harness tail end fixing module are respectively mounted on the X-axis moving mechanism to move along the X-axis direction to adjust the distance between them to accommodate wire harnesses of different lengths, and to keep the wire harness taut and moving during the winding process.

[0012] Furthermore, the synchronous movement of the wire harness head end fixing module and the wire harness tail end fixing module along the X-axis direction, in conjunction with the rotation of the adhesive tape fixing rotating shaft assembly, realizes the coating process of tight wrapping, spaced wrapping, and spot wrapping.

[0013] Furthermore, the CCD module includes a CCD camera and a camera lifting mechanism, the camera lifting mechanism being used to adjust the height of the CCD camera.

[0014] Furthermore, the two sets of tape-wrapping mechanisms are symmetrically arranged on both sides of the rotating base.

[0015] Furthermore, the rotating base is provided with a drive mechanism, which drives the rotating base to rotate, so as to switch between the two sets of tape wrapping mechanisms, so that one set is in the working position and the other set is in preparation.

[0016] Furthermore, the cutting and smoothing module includes a cutting blade and a flattening mechanism, wherein the cutting blade is used to cut the tape, and the flattening mechanism is used to press the end of the tape onto the wire harness after the tape is cut.

[0017] The technical solution of this utility model has the following beneficial effects: 1. Fully automated operation, improving efficiency: This equipment integrates automatic clamping, automatic winding, automatic cutting and automatic pressing and bonding functions, which significantly reduces manual intervention; workers only need to feed materials and perform simple monitoring. After clamping the wire harness once, the machine can complete the entire tape wrapping process, avoiding the tedious operation of repeated manual winding and greatly improving production efficiency.

[0018] 2. Stable winding quality and high precision: The CCD vision module is used to detect the size and position the wire harness before and after winding; the starting position of the tape is accurately positioned before winding, and the wrapping length and tightness are measured after winding to ensure that the tape winding position of each product is accurate and the tightness is consistent; the servo motor driven rotation mechanism ensures uniform winding speed, and the constant clamping force controlled by the pressure sensor can avoid the deviation caused by manual operation and significantly improve the consistency of product quality.

[0019] 3. Strong process compatibility: This machine is compatible with various wire harness coating processes, including tight winding (tight spiral winding), interval winding, and spot winding (fixed-point coating), etc. By setting the ratio between the X-axis movement speed and the rotation speed through the control software, different spacing winding effects can be achieved. It can also be set to stop at a specified position and wind for a certain number of turns to achieve spot winding. One machine can meet the needs of different products and processes, and has a wide range of applications.

[0020] 4. Dual tape winding mechanism reduces downtime: Two sets of tape winding assemblies (one for operation and one for standby) are installed on the rotating base. During normal operation, one set performs the winding task while the other is in standby mode. When it is necessary to change the tape roll or one set of mechanisms malfunctions, the system can quickly switch to the standby mechanism to continue working, avoiding production delays due to material changes or maintenance. The dual-mechanism design reduces the waiting time for tape changes and improves the continuous operation capability of the equipment. Attached Figure Description

[0027] Combination Figures 1-6 As shown, this utility model provides a wire harness tape wrapping machine, comprising: CCD module 1, wire harness clamping mechanism, wire harness fixing module, tape wrapping mechanism; The wire harness clamping mechanism includes: wire harness head end clamping mechanism 2 and wire harness tail end clamping mechanism 3; The wire harness fixing module includes: wire harness head end fixing module 4 and wire harness tail end fixing module 5; The wire harness tail clamping mechanism 3, wire harness tail fixing module 5, adhesive tape wrapping mechanism, wire harness head fixing module 4, and wire harness head clamping mechanism 2 are arranged sequentially from left to right. The wire harness head end fixing module 4 and the wire harness tail end fixing module 5 are respectively mounted on two X-axis moving mechanisms 6, and the head end and tail end of the wire harness are clamped by a gripper cylinder. Both the wire harness head clamping mechanism 2 and the wire harness tail clamping mechanism 3 are equipped with pressure sensors 7 to detect the clamping status of the wire harness. The tape wrapping mechanism includes a rotating base 8 and two sets of tape wrapping mechanisms 9 disposed on the rotating base 8; The CCD module 1 is used for size detection and positioning before and after the tape is wrapped.

[0028] Each tape wrapping mechanism 9 includes a Y-axis assembly 12, a Z-axis assembly 13, a tape fixing and rotating shaft assembly 14, and a cutting and smoothing module; The Y-axis assembly 12 is mounted on the Z-axis assembly 13, the tape-fixed rotating shaft assembly 14 is mounted on the Y-axis assembly 12, and the cutting and smoothing module is mounted on the tape-fixed rotating shaft assembly 14.

[0029] The Y-axis assembly 12 and Z-axis assembly 13 are arranged perpendicularly to each other and are used to drive the tape fixing rotation shaft assembly 14 to move in the vertical and horizontal directions to adjust the winding position of the tape 19.

[0030] The adhesive tape fixing rotating shaft assembly 14 includes: a first motor 15, a driving wheel 16, a driven wheel 17, and an open gear 18; A drive wheel 16 is mounted on the output shaft of the first motor 15. The drive wheel 16 meshes with two driven wheels 17. The two driven wheels 17 mesh with an open gear 18. The tape 19 is mounted on the open gear 18. Driven by the first motor 15, the open gear 18 drives the tape 19 to rotate and wrap around the wire harness.

[0031] The wire harness head end fixing module 4 and the wire harness tail end fixing module 5 are respectively mounted on the X-axis moving mechanism 6 to move along the X-axis direction to adjust the distance between them to accommodate wire harnesses of different lengths, and to keep the wire harness taut and moving during the winding process.

[0032] The synchronous movement of the wire harness head-end fixing module 4 and the wire harness tail-end fixing module 5 along the X-axis direction, in conjunction with the rotation of the adhesive tape fixing rotating shaft assembly 14, realizes the coating process of tight wrapping, spaced wrapping and spot wrapping.

[0033] The CCD module 1 includes a CCD camera 10 and a camera lifting mechanism 11, which is used to adjust the height of the CCD camera 10.

[0034] The two sets of tape wrapping mechanisms 9 are symmetrically arranged on both sides of the rotating base 8.

[0035] The rotating base 8 is provided with a drive mechanism 20, which drives the rotating base 8 to rotate, so as to switch between the two sets of tape wrapping mechanisms 9, so that one set is in the working position and the other set is in preparation.

[0036] The cutting and smoothing module includes a cutting blade 21 and a flattening mechanism 22, wherein the cutting blade 21 is used to cut the tape, and the flattening mechanism 22 is used to press the end of the tape onto the wire harness after the tape is cut.

[0037] The principle of this utility model is as follows: I. Preliminary Stage: Wire Harness Fixing and Clamping The spacing adjustment adapts to the length of the wire harness. The wire harness head end fixing module 4 and the wire harness tail end fixing module 5 are respectively installed on two independent X-axis moving mechanisms 6. According to the actual length of the wire harness to be wound, the two fixing modules are driven to move synchronously or asynchronously along the X-axis direction through the X-axis moving mechanism 6 to adjust the spacing between them and ensure that the two ends of the wire harness can be stably clamped.

[0038] Dual clamping and clamping status detection Two sets of fixed modules clamp the head and tail ends of the wire harness through "clamping cylinders" while keeping the wire harness in a taut state (to prevent the wire harness from loosening or shifting during winding). The wire harness head clamping mechanism 2 and the wire harness tail clamping mechanism 3 synchronously assist in clamping the wire harness, and both are equipped with pressure sensors 7 to detect the clamping force in real time: this prevents the wire harness from slipping due to insufficient clamping force, and also avoids damage to the wire harness due to excessive force, ensuring that the clamping state is qualified.

[0039] II. Before winding: CCD detection and positioning (to ensure winding accuracy) CCD module 1 (including CCD camera 10 and camera lifting mechanism 11) is activated and completes two core tasks: Size detection: Adjust the height of the CCD camera 10 through the camera lifting mechanism 11, align it with the wire harness to be wound, and detect the basic dimensions such as the diameter and length of the wire harness, so as to provide a basis for setting subsequent winding parameters (such as the coverage area of ​​the tape and the winding density); Winding Positioning: Accurately identify the "starting position" and "ending position" of the wire harness to be wrapped with tape, and feed back the positioning signal to the tape winding mechanism to ensure that the winding position is without deviation.

[0040] III. Adhesive Tape Wrapping Mechanism: Switching and Preparation (Improving Work Efficiency) The core of the tape wrapping mechanism is a "rotating base 8 + two sets of symmetrical tape wrapping mechanisms 9", which achieves parallel "operation + preparation" through mechanism switching: The rotating base 8 is equipped with a drive mechanism 20, which drives the base to rotate around the central axis and can be switched between two sets of tape winding mechanisms 9; Switching logic: One set of tape wrapping mechanisms 9 moves to the "working position" (aligned with the area to be wrapped of the wire harness), while the other set is in the "ready position" (the tape installation and parameter adjustment are completed in advance), avoiding downtime and waiting when a single mechanism is working, and improving overall efficiency.

[0041] IV. Adjusting the position of the tape (aligning it with the target area). Each tape wrapping mechanism 9 consists of a Y-axis assembly 12, a Z-axis assembly 13, a tape fixing and rotating shaft assembly 14, and a cutting and smoothing module. The Y-axis assembly 12 and the Z-axis assembly 13 are arranged perpendicularly to each other to achieve precise adjustment of the tape position. Z-axis assembly 13 is fixed on the rotating base 8, Y-axis assembly 12 is mounted on Z-axis assembly 13, and tape is used to fix rotating shaft assembly 14 (including tape 19) mounted on Y-axis assembly 12; The Z-axis assembly 13 drives the Y-axis + tape fixing rotation axis to move in the "vertical direction", and the Y-axis assembly 12 drives the tape fixing rotation axis to move in the "horizontal direction". Combined with the CCD positioning signal, the tape 19 is precisely aligned with the starting position of the wire harness winding.

[0042] V. Core: Adhesive tape wrapping operation (to meet different process requirements) The wrapping operation is completed through the coordinated movement of the "rotation of the tape-fixed rotating shaft assembly 14" and the "X-axis movement of the fixed module," and the specific principle is as follows: 1. Power transmission for tape rotation and winding The transmission structure of the tape fixing rotating shaft assembly 14 is as follows: the output shaft of the first motor 15 drives the driving wheel 16 to rotate; the driving wheel 16 meshes with two driven wheels 17, driving the driven wheels 17 to rotate; the two driven wheels 17 then mesh with the "open gear 18", driving the open gear 18 to rotate; since the tape 19 is installed on the open gear 18, when the open gear 18 rotates, the tape 19 moves in a circular motion around the wire harness synchronously with the gear, realizing the correct wrapping of the tape.

[0043] 2. Implementation of multiple winding processes (dense winding, spaced winding, point winding) The wire harness head-end fixing module 4 and the wire harness tail-end fixing module 5 move synchronously along the X-axis, and their movement speed is coordinated with the rotational speed of the open gear 18 (i.e., the winding speed of the tape 19): If the X-axis movement speed of the fixed module is extremely slow and matched with the rotation speed to achieve "no gap coverage of tape 19", then tight wrapping can be achieved. If the X-axis moving speed and rotation speed of the fixed module are matched in a fixed ratio, the tape 19 will retain a set gap after winding, thus achieving spacing winding; If the fixed module only moves a short distance along the X-axis in a local area, in conjunction with rotation, point wrapping (wrapping tape only at specific points of the wire harness) can be achieved.

[0044] 6. Finishing: Cut and smooth the tape (to ensure wrapping quality) When the winding reaches the set termination position, the cutting and smoothing module is activated: Cutting: The "cutting blade 21" in the module quickly cuts the tape, ensuring a clean cut; Smoothing: After cutting, the "flattening mechanism 22" in the module immediately presses the end of the tape onto the surface of the wire harness to prevent the tape from curling up and to ensure the sealing and stability of the winding.

[0045] 7. After winding: CCD re-inspection (confirming compliance) After the cutting and smoothing are completed, CCD module 1 is restarted to detect the key parameters of the wire harness after winding (such as tape thickness, winding spacing, end smoothing effect, etc.), confirm that the winding quality meets the standards, and complete the entire winding process.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
