Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to an automatic wire harness binding machine. Background Technology

[0002] An automatic wire harness binding machine is a specialized device for automating the binding of wire harnesses. It can automatically complete a series of operations, including feeding, winding, tightening, and cutting of binding tape, through a preset program. The purpose of automatic binding is to replace manual binding, ensuring the consistency and strength of the wire harness binding, avoiding problems such as inconsistent tightness and missed bindings that may occur with manual operation. It also significantly improves the efficiency of wire harness processing and reduces labor costs. It is particularly suitable for mass production scenarios of wire harnesses in industries such as automotive, electronics, and home appliances, providing a stable structural guarantee for the subsequent assembly and use of the wire harnesses.

[0003] After the sensor detects the wire harness, the control system drives the feeding mechanism to deliver the binding tape. After winding and tightening to the set force, the cutting mechanism cuts and locks the binding tape. The whole process is completed automatically according to the preset program, realizing the fast and standardized binding of the wire harness.

[0004] When it is necessary to adapt to wire harnesses of different diameters and materials (requiring different specifications of tightening components), the replacement process requires stopping the machine and manually disassembling the old components and calibrating and installing the new components with tools. This not only takes a long time (possibly tens of minutes), seriously reducing production continuity and efficiency, but may also increase labor costs due to the complexity of the operation and reliance on professional personnel. Therefore, an automatic wire harness binding machine is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic wire harness binding machine, including a base plate 1. A slider 20 is slidably connected to the top of the base plate 1 via a dovetail groove guide rail. A shaped plate 19 is fixedly connected to the top of the slider 20. When the motor 3 drives the rotating rod 4 to rotate, the pulley 6 drives the turntable 7 to rotate the connecting rod 8. At this time, the slider 20 slides synchronously on the base plate 1, effectively dispersing the centrifugal force generated during the rotation of the wire harness and preventing equipment shaking. A rocker plate 11 is rotatably connected to the inner wall of the shaped plate 19 via a pin. The other end of the rocker plate 11 has a waist-shaped groove and is slidably connected to the slider 20 of the connecting rod 8, forming an adjustable lever fulcrum structure. When the switch 12 is pressed, the rocker plate 11 rotates around the pin, realizing the quick disassembly and replacement of the connecting rod 8. The lever principle reduces the operating force, connecting... The rod 8 has two internal sliding connections of two switches 12. Each switch 12 has a slide plate 13 fixedly connected to its adjacent side. The slide plate 13 has a fixed connection of a limit post 14. The limit post 14 is fitted with a spring 15. When the connecting rod 8 needs to be replaced, the switch 12 is pressed inward. The slide plate 13 slides along the limit post 14 to compress the spring 15, causing the limit block 17 to disengage from the slot of the irregular plate 19, thus achieving quick unlocking. After the switch 12 is released, the elastic restoring force of the spring 15 causes the slide plate 13 to return to its original position, ensuring connection stability. The spring preload ensures the reliability of the buckle connection. The top of the base plate 1 is fixedly connected to a stabilizing component. One end of the stabilizing component is fixedly connected to a clamping component. Through the multi-angle adjustment function of the stabilizing component, the clamping component can accurately align the wire harness at different positions for binding operations.

[0033] A support block 32 is fixedly connected to the top of the base plate 1. The top of the support block 32 has a V-shaped groove to support the middle of the longer wire harness and prevent the wire harness from sagging and deforming during rotation. Multiple buffer columns 33 are fixedly connected to the bottom of the base plate 1. The buffer columns 33 are made of rubber and can effectively absorb the vibration energy generated during the operation of the equipment and reduce the impact on the working environment. Based on the vibration damping principle of viscoelastic materials, a limit block 17 is fixedly connected to the outside of the slide plate 13. The cross section of the limit block 17 is a trapezoidal structure, which cooperates with the trapezoidal slot on the irregular plate 19 to ensure positioning accuracy and ensure the repeatability of the position of the connecting rod 8 after installation. A spring 18 is fixedly connected to the top of the connecting rod 8. A clamping plate 10 is fixedly connected to the other end of the spring 18, which can reliably fix the wire harness and prevent the insulation layer of the wire harness from being damaged due to excessive pressure.

[0034] A support plate 2 is fixedly connected to the top of the base plate 1. A motor 3 is fixedly connected to the top of the support plate 2 by bolts. A rotating rod 4 is fixedly connected to the drive end of the motor 3 by a coupling. Two turntables 5 are rotatably connected to the outside of the rotating rod 4 by a flat key. A pulley 6 is rotatably connected to the inside of the turntable 5 by a bearing. A turntable 7 is rotatably connected to the other side of the pulley 6 by a flat key. The other end of the turntable 7 is movably connected to the inner wall of the connecting rod 8 by a slider 20. When the motor 3 drives the rotating rod 4 to rotate, the turntable 7 drives the connecting rod 8 to make a circular motion through belt transmission, ensuring that the wire harness obtains a stable rotation speed. Based on the motion transmission principle of belt transmission, a fixing block 9 is fixedly connected to the top of the connecting rod 8. The bottom of the rocker 11 is rotatably connected to the outside of the fixing block 9 by a pin, forming a lever fulcrum, realizing the quick disassembly and replacement of the connecting rod 8.

[0035] Reference Figure 2 and Figure 4 The stabilizing component includes a fixed base 21, the bottom of which is rotatably connected to the top of the base plate 1 via a bearing. The inner wall of the fixed base 21 is rotatably connected to a follower plate 22 via a spherical bearing. The other end of the follower plate 22 is rotatably connected to a driven plate 23 via a ball joint. This structural design enables the clamping component to have three degrees of freedom adjustment capability. The driven plate 23 can be adjusted by ±15° of yaw angle via a ball joint. Through this multi-joint linkage design, the operator can quickly align the clamping block 30 with wire harnesses of different diameters and positions, significantly improving the flexibility of the strapping operation.

[0036] The clamping assembly includes a connecting block 24, which is externally fixedly connected to the outside of the driven plate 23. A pneumatic cylinder 25 is fixedly connected to the inner wall of the connecting block 24. A follower block 26 is fixedly connected to the drive end of the pneumatic cylinder 25. Two rotating blocks 27 are rotatably connected inside the pneumatic cylinder 25 via a pin. A connecting plate 28 is rotatably connected inside the rotating blocks 27 via a pin. When the piston rod of the pneumatic cylinder 25 extends, the follower block 26 pushes the rotating block 29 to open outward. The rotating blocks 27 rotate around the pin. Through the linkage of the connecting plate 28, the two clamping blocks 30 close inward synchronously, achieving stable clamping of the wire harness. This structure adopts a parallelogram linkage mechanism design to ensure that the clamping blocks 30 maintain parallel movement during the closing process, avoiding damage to the wire harness due to shearing force.

[0037] The follower block 26 has two rotating blocks 29 rotatably connected internally via pins. The exterior of rotating blocks 29 is rotatably connected to the interior of rotating block 27 via pins. The other end of rotating block 27 is rotatably connected to a clamping block 30 via a pin. The exterior of clamping block 30 is rotatably connected to a connecting plate 28 via a pin. This double-rocker mechanism design enables clamping block 30 to achieve a self-centering effect when closed. Regardless of changes in the wire harness diameter, the center of clamping block 30 always coincides with the axis of the pneumatic cylinder 25, ensuring consistent strap position. Simultaneously, the length design of the connecting plate 28 creates a mechanical dead point at the closing end position of clamping block 30, preventing loosening due to air pressure fluctuations and improving the stability of the binding quality.

[0038] Reference Figure 1 and Figure 2 The outer side of the rotating rod 4 is rotatably connected to the limit ring 16 through an interference fit. The bottom of the limit ring 16 is fixedly connected to the top of the base plate 1 by bolts, which effectively limits the radial runout of the rotating rod 4 and ensures the smoothness of the belt drive.

[0039] The top of the base plate 1 is fixedly connected to the protective cover 31 by bolts. The outside of the rotating rod 4 is rotatably connected to the inner wall of the protective cover 31 by bearings. The protective cover 31 adopts a sheet metal forming structure and the surface is powder coated. It can not only prevent operators from contacting the rotating parts, but also effectively block dust from entering the transmission system and extend the service life of the equipment.

[0040] Working principle: Press one side of the clamp (10), pick up the wire harness and align one end with the bottom of the clamp (10). The spring 2 (18) will rebound and fix the wire harness. Repeat the operation on the other end of the wire harness. Start the motor (3) to drive the rotating rod (4) to rotate, so that the first turntable (5) pulls the belt pulley (6) to rotate, so that the second turntable (7) rotates, so that the connecting rod (8) drives each wire harness to rotate. At this time, pick up the driven plate (23), pull the follower plate (22), and pick up the connecting block (24) to align with the appropriate position. Start the pneumatic cylinder (25) to drive the follower block (26) to move, pull the second turntable (29) to move the first turntable on both sides (27) and move with the follower block (26), so that the connecting plate (28) moves and the clamping block (30) is restricted to prevent deviation. The wire harness is clamped and wound.

[0041] When the connecting rod (8) is damaged due to excessive use, pressing the switch (12) will cause the slide plate (13) to move, thereby releasing the limit block (17) from restricting the rocker (11). The limit post (14) will prevent the slide plate (13) from deviating, and the spring (15) will bounce the switch (12) back.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
