Description

Technical Field

[0001] This application relates to the field of wire harness manufacturing technology, and in particular to a wiring harness bundling tool for automobiles. Background Technology

[0002] As a core component of a vehicle's electrical system, automotive wiring harnesses undertake critical functions such as power transmission, signal control, and data interaction. With the increasing electrification and intelligence of automobiles, wiring harness structures are becoming increasingly complex, with more branches and wider differences in wire diameters, while also meeting stringent requirements such as lightweighting, high temperature resistance, and vibration resistance. During automobile manufacturing, wiring harnesses undergo multiple processes, including cutting, stripping, terminal crimping, and branch assembly, and are ultimately bundled and fixed to form modular components for easy vehicle assembly.

[0003] In related technologies, traditional automotive wiring harness bundling mostly relies on manual wrapping of tape, which requires repeated adjustments to the tape position and tension. The efficiency and consistency of manual bundling are difficult to guarantee, and it is easy to cause long time consumption for bundling a single piece. In addition, the bundling angle and tension are inconsistent, which cannot meet the standardization requirements of mass production of automotive wiring harnesses. Therefore, it needs to be improved. Utility Model Content

[0004] To address the issues of low efficiency and consistency in manual bundling, this application provides an automotive wiring harness bundling fixture.

[0005] The automotive wiring harness bundling fixture provided in this application adopts the following technical solution:

[0006] A wiring harness bundling fixture includes a fixture plate with a fixture column vertically arranged on the fixture plate. A bundling seat is provided on the fixture column, and a lifting mechanism for lifting the bundling seat is provided on the fixture column. A bundling mechanism is provided on the bundling seat. The bundling mechanism includes two vacuum adsorption plates and two tilting cylinders. The two vacuum adsorption plates are symmetrically hinged on both sides of the bundling seat and spaced apart. Each vacuum adsorption plate has several adsorption holes on its working surface. The two tilting cylinders correspond to the two vacuum adsorption plates respectively. The cylinder body of the tilting cylinder is inclined on the bundling seat, and the piston end of the tilting cylinder is hinged to the back of the corresponding vacuum adsorption plate.

[0007] Traditional automotive wiring harness bundling largely relies on manual wrapping of tape, requiring repeated adjustments to the tape position and tension. This manual bundling is inefficient and inconsistent, often resulting in long bundling times per unit and poor consistency in bundling angle and tension, failing to meet the standardization requirements of mass production of automotive wiring harnesses. By adopting the above-mentioned technical solution, including a tooling plate, tooling columns are vertically fixed on the tooling plate, and a lifting mechanism is provided on the tooling columns to drive the bundling seat to rise and fall. At the same time, the bundling seat is equipped with a bundling mechanism, which includes two vacuum suction plates and two tilting cylinders.

[0008] When bundling automotive wiring harnesses, the tape is cut to a predetermined length using an unwinding device. Both ends of the tape are placed on the working surfaces of two vacuum adsorption plates. Negative pressure is created through the adsorption holes, firmly adsorbing both ends of the tape onto the vacuum adsorption plates. The middle portion of the tape hangs naturally, suspended in the center of the bundling seat. The automotive wiring harness to be bundled is then transported to the bundling station via a conveyor or robotic arm, precisely positioned within the wiring harness groove. Two flipping cylinders are simultaneously activated, with the pistons pushing the vacuum adsorption plates to flip inward around the hinge axis. This flipping action causes the two ends of the tape to converge from both sides towards the wiring harness. The adhesive surfaces of the tape automatically bond upon contact, forming a closed-loop bundling structure. After bundling, the negative pressure in the adsorption holes disappears, the tape completely detaches from the vacuum adsorption plates, the flipping cylinders retract, and the vacuum adsorption plates return to a horizontal position. Simultaneously, if adjustments to the bundling position are needed or to adapt to subsequent processes, the lifting cylinder drives the lifting platform to rise and fall along the tooling column, causing the bundling seat to move vertically.

[0009] By incorporating a strapping base, vacuum adsorption plate, and flipping cylinder, the system facilitates precise tape adsorption, automatic wrapping, and closed-loop bonding, effectively replacing traditional manual strapping methods. This significantly improves strapping efficiency and consistency, ensuring the standardized requirements for mass strapping of automotive wiring harnesses.

[0010] Optionally, the vacuum adsorption plate is provided with a vacuum channel inside, and the vacuum adsorption plate is provided with a vacuum interface for connecting to a vacuum.

[0011] By adopting the above technical solution, the vacuum channel is formed inside the vacuum adsorption plate, and the vacuum interface is installed on the vacuum adsorption plate. The vacuum interface facilitates quick connection to an external vacuum source, enabling flexible start and stop of the adsorption function.

[0012] Optionally, the two vacuum adsorption plates are rotatably mounted on the strapping seat, and the strapping seat has support bosses on both sides for engaging with the bottom surface of the vacuum adsorption plates.

[0013] By adopting the above technical solution, the support boss is integrally formed on the strapping seat. When the vacuum adsorption plate is in a horizontal position, the support boss fits and limits the bottom surface of the vacuum adsorption plate. By setting the support boss, the angular deviation of the adsorption plate caused by gravity or external force shaking is effectively reduced, ensuring the flatness and stability of the adsorption plate in the non-working state, and providing a stable reference surface for tape placement.

[0014] Optionally, the binding seat has a wire harness groove in the middle, which is located between two vacuum adsorption plates.

[0015] By adopting the above technical solution, the wire harness groove is opened in the middle of the binding seat; the setting of the wire harness groove effectively constrains the position of the wire harness, prevents it from shifting or moving when the tape is flipped and wrapped, ensures that the binding area is precisely aligned with the hanging position of the tape, and improves the tightness of the binding.

[0016] Optionally, the lifting mechanism includes a lifting platform, a lifting slider, and a lifting cylinder. The tooling column has a lifting groove along the height direction. The lifting slider is slidably connected in the lifting groove. The lifting platform is connected to the lifting slider. The binding seat is arranged on the lifting platform. The cylinder body of the lifting cylinder is connected to the tooling plate, and the piston end of the lifting cylinder is connected to the bottom of the lifting platform.

[0017] By adopting the above technical solution, the lifting mechanism includes a lifting platform, a lifting slider, and a lifting cylinder. When it is necessary to adjust the binding position or adapt to subsequent processes, the lifting cylinder is activated, driving the lifting platform to rise and fall along the tooling column. The lifting slider is slidably connected in the lifting groove, driving the binding seat to move vertically. Through the setting of the lifting mechanism, the vertical lifting and lowering control of the binding seat is realized, which can be flexibly adjusted according to the needs of the wire harness and adapted to multi-station connection or subsequent processing processes.

[0018] Optionally, a set of fastening bolts for fixed connection is provided between the lifting slider and the lifting platform, and the number of fastening bolts is multiple.

[0019] By adopting the above technical solution, the lifting slider and the lifting platform are fixed together by fastening bolts; the setting of fastening bolts ensures the structural stability during lifting movement, effectively reduces the tilting or vibration of the lifting platform, and facilitates disassembly and maintenance in the future.

[0020] Optionally, the tooling column is provided with an upper limit sensor and a lower limit sensor at intervals along the height direction, and the lifting slider is provided with a limiting protrusion for cooperating with the upper limit sensor and the lower limit sensor.

[0021] By adopting the above technical solution, the upper limit sensor and the lower limit sensor are installed alternately on the tooling column, and the limit protrusion is installed on the lifting slider. The limit protrusion cooperates with the upper limit sensor and the lower limit sensor. With the setting of the limit protrusion, the upper limit sensor and the lower limit sensor, when the lifting slider drives the strapping seat to rise and fall, the limit protrusion triggers the sensor to monitor in real time and forcibly interrupt the overtravel action of the lifting cylinder, so as to prevent the equipment from overtravel collision due to misoperation or failure, and improve the safety of the equipment.

[0022] Optionally, the tooling column is provided with two linear slide rails, which correspond to the upper limit sensor and the lower limit sensor respectively. Both the upper limit sensor and the lower limit sensor are provided with linear sliders, which are slidably connected in the corresponding linear slide rails, and the linear sliders are provided with locking bolts for locking the position.

[0023] By adopting the above technical solution, two linear slide rails are installed on the tooling column, and linear sliders are installed on the upper limit sensor and the lower limit sensor. At the same time, locking bolts are installed on the linear sliders. The arrangement of linear slide rails, linear sliders and locking bolts helps to adjust the position of the sensors to adapt to different strokes. Meanwhile, the locking bolts can firmly lock the position of the sensors, reduce displacement deviation caused by vibration or impact, and ensure the accuracy of limit detection.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The design, including the strapping seat, vacuum adsorption plate, and flipping cylinder, facilitates precise tape adsorption, automatic wrapping, and closed-loop bonding, effectively replacing the traditional manual strapping method, significantly improving strapping efficiency and consistency, and ensuring the standardization requirements for batch strapping of automotive wiring harnesses.

[0026] 2. By setting up the support boss, the angle deviation of the adsorption plate caused by gravity or external force is effectively reduced, ensuring the flatness and stability of the adsorption plate in the non-working state, and providing a stable reference surface for tape placement.

[0027] 3. By setting limit protrusions, upper limit sensors, and lower limit sensors, when the lifting slider drives the strapping seat to rise and fall, the limit protrusion trigger sensor can monitor in real time and forcibly interrupt the overtravel action of the lifting cylinder, preventing the equipment from overtravel collisions due to misoperation or malfunction, thus improving equipment safety.

[0032] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0033] This application discloses an automotive wiring harness bundling fixture. (Refer to...) Figure 1 The automotive wiring harness bundling fixture includes a fixture plate 1, a fixture column 2 vertically mounted on the fixture plate 1, and a bundling seat 3 arranged on the fixture column 2. In this embodiment, the bundling seat 3 is equipped with a bundling mechanism 5, which is used to bundle the wiring harness. At the same time, the fixture column 2 is equipped with a lifting mechanism 4, which is used to drive the bundling seat 3 to lift.

[0034] Reference Figure 1 and Figure 2 The lifting mechanism 4 includes a lifting platform 41, a lifting slider 42, and a lifting cylinder 43. A lifting groove 21 is provided on the tooling column 2. The lifting slider 42 is slidably connected in the lifting groove 21. The lifting platform 41 is located outside the tooling column 2 and is fixedly connected to the lifting slider 42. Fastening bolts 10 are installed between the lifting slider 42 and the lifting platform 41. There are multiple sets of fastening bolts 10, which are used to fix the lifting slider 42 and the lifting platform 41.

[0035] Reference Figure 1 and Figure 2 The strapping seat 3 is installed on the lifting platform 41, and the lifting cylinder 43 is vertically installed on the tooling plate 1. The cylinder body of the lifting cylinder 43 is arranged on the tooling plate 1, and the piston end of the lifting cylinder 43 is connected to the bottom of the lifting platform 41. This realizes the vertical lifting control of the strapping seat 3, which can be flexibly adjusted according to the needs of the wire harness and adapted to multi-station connection or subsequent processing procedures.

[0036] Reference Figure 1 and Figure 3 The tooling column 2 is equipped with an upper limit sensor 11 and a lower limit sensor 12, which are arranged at intervals along the height direction of the tooling column 2. The lifting slider 42 is equipped with a limit protrusion 13, which cooperates with the upper limit sensor 11 and the lower limit sensor 12. The limit protrusion 13 and the upper limit sensor 11 and the lower limit sensor 12 can be contact or non-contact. When the lifting slider 42 drives the strapping seat 3 to rise and fall, the limit protrusion 13 triggers the sensor to monitor in real time and forcibly interrupt the overtravel action of the lifting cylinder 43, preventing the equipment from overtravel collision due to misoperation or failure, thus improving the safety of the equipment.

[0037] Reference Figure 1 and Figure 2Two linear slide rails 14 are installed on the tooling column 2. The linear slide rails 14 are arranged along the height direction of the tooling column 2. The two linear slide rails 14 correspond to the upper limit sensor 11 and the lower limit sensor 12, respectively. A linear slider 15 is installed on both the upper limit sensor 11 and the lower limit sensor 12. The linear slider 15 is slidably connected in the corresponding linear slide rail 14, and a locking bolt 16 is installed on the linear slider 15. The locking bolt 16 is used to lock the position of the linear slider 15. This helps to realize the position adjustment of the sensor to adapt to different strokes. At the same time, the locking bolt 16 can firmly lock the position of the sensor, reduce the displacement deviation caused by vibration or impact, and ensure the accuracy of limit detection.

[0038] Reference Figure 1 The strapping mechanism 5 includes two vacuum adsorption plates 51 and two flipping cylinders 52. The two vacuum adsorption plates 51 are symmetrically hinged on both sides of the strapping base 3, and the two vacuum adsorption plates 51 are arranged at intervals. In this embodiment, the vacuum adsorption plates 51 can be hinged by a hinge shaft. The vacuum adsorption plates 51 have a vacuum channel formed inside, and a vacuum interface 7 is installed on the vacuum adsorption plates 51. The working surface of the vacuum adsorption plates 51 is provided with several adsorption holes 6. The vacuum interface 7 facilitates quick access to an external vacuum source, and the tape is adsorbed by negative pressure through the adsorption holes 6 via the vacuum channel.

[0039] Reference Figure 1 Meanwhile, both sides of the strapping seat 3 are integrally formed with support bosses 8. When the vacuum adsorption plate 51 is in a horizontal position, the support bosses 8 fit and limit the bottom surface of the vacuum adsorption plate 51, effectively reducing the angle deviation caused by gravity or external force shaking of the adsorption plate, ensuring the flatness and stability of the adsorption plate in the non-working state, and providing a stable reference surface for tape placement.

[0040] Reference Figure 1 Two flipping cylinders 52 correspond to two vacuum adsorption plates 51 respectively. The cylinder body of the flipping cylinder 52 is installed at an angle on the binding seat 3. The piston end of the flipping cylinder 52 is hinged to the back of the corresponding vacuum adsorption plate 51. When the flipping cylinder 52 is started synchronously, the piston end pushes the vacuum adsorption plate 51 to flip inward around the hinge axis. The flipping action causes the two ends of the tape to close from both sides towards the wire harness. After the adhesive surfaces of the tape come into contact, they automatically bond together to form a closed loop binding structure.

[0041] Reference Figure 1 The binding seat 3 has a wire harness groove 9 in the middle, which is located between two vacuum adsorption plates 51. The wire harness groove 9 can effectively constrain the position of the wire harness and prevent it from shifting or moving when the tape is flipped and wrapped, ensuring that the binding area is precisely aligned with the hanging position of the tape, thereby improving the tightness of the binding.

[0042] The implementation principle of the automotive wiring harness bundling fixture in this application embodiment is as follows: When bundling automotive wiring harnesses, the tape is cut to a predetermined length using an unwinding device. Both ends of the tape are placed on the working surfaces of two vacuum adsorption plates 51. A negative pressure is formed through the adsorption holes 6, firmly adsorbing both ends of the tape onto the vacuum adsorption plates 51. At this time, the middle portion of the tape hangs naturally, suspended above the wiring harness groove 9 in the middle of the bundling seat 3. The automotive wiring harness to be bundled is transported to the bundling station via a conveyor or robotic arm, precisely positioned within the wiring harness groove 9, and then flipped over. The cylinder 52 starts synchronously, and the piston end pushes the vacuum adsorption plate 51 to rotate inward around the hinge axis. The rotation action causes the two ends of the tape to come together from both sides towards the wire harness. After the adhesive surfaces of the tape come into contact, they automatically bond together to form a closed-loop binding structure. After binding is completed, the negative pressure of the adsorption hole 6 disappears, and the tape is completely separated from the vacuum adsorption plate 51. The rotating cylinder 52 retracts, and the vacuum adsorption plate 51 returns to the horizontal position. At the same time, if it is necessary to adjust the binding position or adapt to subsequent processes, the lifting cylinder 43 drives the lifting platform 41 to rise and fall along the tooling column 2, which drives the binding seat 3 to move vertically.

[0043] The use of strapping seat 3, vacuum adsorption plate 51, and flipping cylinder 52 helps to achieve precise adsorption, automatic wrapping, and closed-loop bonding of tape, effectively replacing the traditional manual strapping method, significantly improving strapping efficiency and consistency, and ensuring the standardization requirements of batch strapping of automotive wiring harnesses.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
