Description

Technical Field

[0001] The present invention belongs to the technical field of wire harness bundling, and particularly relates to a quick-change adjustable-angle automatic cable tie device. Background Art

[0002] In recent years, with the increasing global awareness of environmental protection and the adjustment of the energy structure, the new energy vehicle market has shown a rapid growth trend. As the world's largest new energy vehicle market, China's production and sales have continued to climb in recent years. The high-voltage wire harnesses and a large number of wire harnesses required for intelligent networking inside new energy vehicles need to be bundled and fixed, resulting in a sharp increase in the demand for automotive wire harness bundling.

[0003] The quality and stability of wire harness connections directly affect the quality of the whole vehicle. Through in-depth market research, it is found that in the current field of new energy vehicle manufacturing, most automobile factories still use manual wire harness cable ties, which have many disadvantages. First of all, manual operation is inefficient, greatly affecting the production speed of automobiles and increasing production costs; secondly, the consistency of manual cable ties is difficult to guarantee, and it is easy to have the situation of too loose or too tight cable ties. When the tying force is too large, the wire harness may be folded, and when the tying force is too small, the wire harness may not be fixed firmly. Both of these situations affect the stability and safety of the wire harness. Long-term manual operation is likely to cause worker fatigue, and there may be phenomena of operation errors, posing safety hazards to the vehicle. At present, the automatic bundling equipment adopted by most enterprises is very expensive and has poor universality.

[0004] Therefore, in order to meet the requirements of new energy vehicles for lightweight, intelligent, high-temperature tolerance, and environmentally friendly materials, this solution proposes a quick-change adjustable-angle automatic cable tie device to solve various technical problems of the above-mentioned manual wire harness cable ties.

[0015] The cutting structure includes a cutting cylinder, a movable cutter head fixedly connected to the free end of the cutting cylinder, and a fixed cutter head fixed on the housing structure. The movable cutter head is arranged to move close to the fixed cutter head.

[0019] The beneficial technical effects of the present invention are as follows:

[0020] (1) A cable tie pushing structure is designed, which cooperates with the movable limiting assembly and the binding adjusting assembly to achieve the following technical effects:

[0021] First, under the action of the air source, the small end of the cable tie is in the front and moves quickly along the pneumatic pipeline to contact with one end of the spring and the wedge block. The large head of the cable tie is blocked by the two wedge blocks on both sides, and the large head of the cable tie is stably clamped under the action of the spring.

[0022] Second, under the action of the first limiting cylinder and the second limiting cylinder, the first guiding block and the second guiding block approach both sides of the cable tie, so that the cable tie passes through the two limiting grooves, realizing the stability of the cable tie and avoiding the deviation of its position.

[0023] Third, by using the upper arc rod and the lower arc rod that are slidably connected to each other, the cable tie slides in the lower arc groove and the upper arc groove, bypasses the wire harness, slides out from the inner end of the upper arc rod, and extends into the large head of the cable tie;

[0024] (2) A pulling structure is provided. Under the action of the servo motor, the first pressing wheel and the second pressing wheel are driven to rotate, and the small end of the cable tie is pressed downward, thereby realizing the binding and tensioning of the wire harness;

[0025] Subsequently, the cutting cylinder is started. The cable tie passes between the movable cutter head and the fixed cutter head. The movable cutter head is close to the fixed cutter head position, realizing the cutting of the cable tie, which is convenient and fast, and improves the work efficiency;

[0026] (3) In this solution, the second rotating rod assembly is designed. On the one hand, it can lift the bound wire harness, so that the large head of the cut cable tie is separated from the housing structure, and the wire harness advances for the next round of binding; on the other hand, an air pipe, an air passage, and an air pump are provided. Under the action of the air pump, air is introduced into the air pipe and sprayed from the side of the vertical part towards the side of the cable tie, ensuring that the cable tie is closely attached to the upper arc groove, so as to ensure that the small end of the cable tie accurately extends into the large head of the cable tie, ensuring the stability of the work;

[0027] (4) There is a first rotating rod assembly, which cooperates with the second rotating rod assembly. The upward rotation of the first rotating rod and the second rotating rod causes the wire harness to rise under the lifting of the two, so that the large head of the cut cable tie is separated from the housing structure, so that the next round of binding action can be carried out smoothly;

[0028] (5) This equipment has the characteristics of high efficiency, accuracy, and stability, and can meet the production needs of the automotive manufacturing industry. The initial version of this equipment has been successfully applied to the wire harness production line of an automotive parts enterprise and the R & D project of a certain institute of the Chinese Academy of Sciences, reducing the production cost of the enterprise by about 120,000 yuan and obtaining good market feedback; specifically reflected in the following points:

[0029] First, it improves production efficiency. Automatic bundling and assembly can significantly speed up the bundling speed of wire harnesses, reduce the time of manual operation, thereby improving the overall production efficiency, and ensuring the product delivery cycle and the profitability of the enterprise in the intelligent manufacturing environment;

[0030] Second, it reduces labor costs. Traditional wire harness bundling requires a large amount of manual operation, while automatic bundling and assembly can greatly reduce the labor intensity of workers, and even completely replace manual labor in some cases. This not only reduces labor costs, but also reduces errors and wastes caused by worker fatigue or improper operation;

[0031] Third, it improves product quality. Through precise mechanical structures and control systems, it can ensure the uniformity and consistency of each bundling, thereby improving product quality and reducing wire harness failures and safety hazards caused by poor bundling;

[0032] Fourthly, it enhances production flexibility. The equipment is equipped with a control system and can be flexibly adjusted according to different wire harness specifications and bundling requirements. This flexibility enables the production line to quickly adapt to market changes and product updates, improving the competitiveness and response speed of the enterprise;

[0033] Fifthly, it promotes energy conservation and emission reduction. By reducing manual operations and waste, it helps to reduce energy consumption and emissions during the production process. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0046] In order to more clearly illustrate the technical features of this solution, the following elaborates on this solution through specific implementation manners.

[0047] See Figures 1 - 3 、 Figure 10 , a quick-change adjustable-angle automatic cable tie device, including a housing structure. Inside the housing structure, there are provided a cable tie pushing structure for the forward movement of the cable tie 13, a movable limit assembly 4 for laterally limiting the cable tie 13, a binding adjustment assembly for bending the small end of the cable tie and inserting it into the cable tie head 131, a pulling structure for tensioning the cable tie 13 against the wire harness 3, and a cutting structure for cutting the cable tie 13. The cable tie pushing structure is connected to the pneumatic pipeline 7, and the pneumatic pipeline 7 is connected to a gas source. A cable tie pipe 71 is communicatively provided on the side of the pneumatic pipeline 7.

[0048] Among them, the housing structure includes an outer shell one 1 and an outer shell two 8 that are butt-jointed with each other by bolts. A switch door 2 is provided on the outer shell one 1 for removing the remaining cable tie materials after cutting.

[0049] See Figure 6 , the cable tie pushing structure includes a toothed plate 6 that slides horizontally inside the housing structure, a power gear 61 that is meshed and connected above the toothed plate 6, a power motor that is drivingly connected to the power gear 61, and a chuck 62 that is detachably connected to the bottom end of the toothed plate 6. The chuck 62 is provided with a horizontal through hole. On both sides of one end of the horizontal through hole, springs 621 are respectively provided. One end of each spring 621 is connected to a wedge block 622;

[0050] The horizontal perforation is connected to the pneumatic pipeline 7, and the two wedge blocks 622 are detachably clamped on both sides of the large head 131 of the cable tie. When the large head 131 of the cable tie advances, the wedge block 622 squeezes the spring 621, and the wedge block 622 slides out from the large head 131 of the cable tie and easily disengages from the large head 131 of the cable tie.

[0051] See Figures 7 - 9 , the movable limit assembly 4 includes a first limit cylinder 41, a first fixed block 411 fixedly connected to the free end of the first limit cylinder 41, a first guide block 412 fixedly connected to the first fixed block 411, a second limit cylinder 42, a second fixed block 421 fixedly connected to the free end of the second limit cylinder 42, and a second guide block 422 fixedly connected to the second fixed block 421. The first limit cylinder 41 and the second limit cylinder 42 are respectively arranged on both sides of the cable tie 13, and the first guide block 412 and the second guide block 422 are respectively arranged on both sides of the cable tie 13;

[0052] Limit slots 413 are provided on both the first guide block 412 and the second guide block 422, and two adjacent limit slots 413 are butted. The cable tie 13 passes through and is movably clamped in the two limit slots 413. The inlet of the limit slot 413 is of a flared structure, and the outlet is of a constricted structure, which helps to enter and limit the cable tie.

[0053] See Figure 4 and Figure 5 , the binding adjustment assembly includes a lower arc rod 12, an upper arc rod 94 detachably butted with one end of the lower arc rod 12, and a worm and worm gear structure 9 fixedly connected to the other end of the upper arc rod 94. A lower arc groove 121 is provided on the inner side of the lower arc rod 12, and an upper arc groove 95 is provided on the inner side of the upper arc rod 94. One end of the upper arc rod 94 is slidably connected in the lower arc groove 121. The small end of the cable tie 13 sequentially slides through the lower arc groove 121, the upper arc groove 95, and is arranged on the large head 131 of the cable tie; the bottom end of the lower arc rod 12 is connected to the rotation adjustment assembly.

[0054] Specifically, under an external force, the cable tie 13 first passes through the lower arc groove 121, and then the small end of the cable tie contacts one end of the upper arc rod 12. One end of the upper arc rod 12 abuts against the small end of the cable tie, causing the movement track of the small end of the cable tie to change and enter the upper arc groove 95. Then it winds around the inside of the upper arc groove 95 and disengages from one end of the upper arc groove 95, and is inserted into the large head 131 of the cable tie from top to bottom. At this time, the cable tie 13 has wound up the wire harness 3.

[0055] Preferably, the rotation adjustment assembly includes a vertically arranged rotating column 122, a driving gear 123 coaxially connected to the bottom end of the rotating column 122, a rack 124 meshingly connected to the driving gear 123, and a pushing cylinder 125 fixedly connected to one end of the rack 124. When the pushing cylinder 125 operates, it drives the linear movement of the rack 124, and then drives the rotation adjustment of the driving gear 123, thereby driving the rotation adjustment of the rotating column 122.

[0056] See Figure 4 and Figure 5 , the worm and worm gear structure 9 includes a worm gear 92, a rotating shaft 96 coaxially connected to the center of the worm gear 92, a worm 91 meshingly connected to the worm gear 92, a driving motor drivingly connected to the worm 91, and a fixing part 93 fixedly connected to the meshing part of the worm gear 92. The fixing part 93 is fixedly connected to the outer side of the upper arc-shaped rod 94. The two ends of the rotating shaft 96 are rotatably connected to the protective cover 5, and the protective cover 5 is fixed to the housing structure. Under the action of the driving motor, the worm 91 is driven to rotate, and then the worm gear 92 is driven to rotate, thereby driving the rotation adjustment of the upper arc-shaped rod 94.

[0057] See Figure 6 , the pulling structure includes a driving gear 144 and a driven gear 147 meshingly connected to each other, a servo motor 143 drivingly connected to the driving gear 144, a first pressing wheel 145 coaxially connected to the driving gear 144, and a second pressing wheel 146 coaxially connected to the driven gear 147. The small end of the cable tie 13 moves through the space between the first pressing wheel 145 and the second pressing wheel 146.

[0058] Preferably, a first axle passes through the first pressing wheel 145, a second axle passes through the second pressing wheel 146, and a torque sensor is provided on the first axle or the second axle. The torque sensor is connected to a PLC controller, and the PLC controller controls the operation or stop of the servo motor 143.

[0059] Through the torque sensor, it is judged how tight the cable tie 13 winds the wire harness. The greater the torque, the greater the bundling strength of the wire harness; the smaller the torque, the smaller the bundling strength of the wire harness. A certain torque value is set, and when this torque value is reached, the pulling stops.

[0060] The torque sensor is a prior art. In use, the torque sensor is generally connected to the housing structure through hub couplings at both ends of the shaft, and the working principle will not be elaborated here.

[0061] See Figure 6, the cutting structure includes a cutting cylinder 14, a movable cutter head 141 fixedly connected to the free end of the cutting cylinder 14, and a fixed cutter head 142 fixed on the housing structure. The movable cutter head 141 is arranged to move closer to the fixed cutter head 142; the movable cutter head 141 and the fixed cutter head 142 are arranged above the pulling structure. The cable tie 13 passes between the movable cutter head 141 and the fixed cutter head 142, and the two cutter heads approach each other to cut the cable tie.

[0062] The specific working process of the present invention is as follows:

[0063] (1) Automatic feeding through the air source:

[0064] The cable tie 13 is transmitted into this device by the pneumatic pipeline 7. The spring wedge mechanism (including a spring 621 and a wedge block 622) blocks the large head 131 of the cable tie. The inner hole of the pipeline (i.e., Figure 2 the round hole in the middle of the middle chuck 62) is slightly smaller than the large head 131 of the cable tie to ensure that the cable tie 13 moves forward together with the chuck 62. During operation, the power motor drives the power gear 61 and the toothed plate 6 to move. The power gear 61 drives the cable tie 13 clamped with the chuck 62 forward together. When the bundling is completed and the bundling force is large, the small end of the cable tie is pulled down, the wedge block 622 is forced to open on both sides, and the spring 621 is compressed to facilitate the smooth removal of the cable tie 13;

[0065] It should be noted that the structure of the pipeline pneumatic valve mainly includes a valve body, a valve core, a spring 621, an air source interface, etc.; its working principle is based on the pressure difference of the gas, and the opening and closing of the valve are realized by controlling the flow of the gas. The specific working principle is as follows: When compressed air is introduced into the air source interface, the gas enters the valve body through the filter and pushes the valve core to move; when the valve core moves to a certain position, it will open or close the valve, thereby controlling the flow of the gas; when there is no compressed air input at the air source interface, the spring 621 will push the valve core back to the original position to close the valve; in this way, the pipeline pneumatic valve can achieve precise control of the gas flow.

[0066] A cable tie tube 71 is arranged outside the entrance of the pneumatic pipeline 7, which is in a bifurcated structure. The pneumatic pipeline 7 is connected to the air source, and the cable tie tube 71 inputs the cable tie. The cable tie 71 can be manually fed. The cable tie 13 is placed in the cable tie tube 71, and the cable tie 13 slides into the pneumatic pipeline 7 under gravity. The air source directly blows the cable tie 13 into the interior of the pneumatic pipeline 7 and pushes the cable tie 13 to move inside the pneumatic pipeline 7 under a certain pressure, finally forcing the wedge block 622 to be stressed and open its two sides, and using the spring 621 and the wedge block 622 to squeeze the cable tie 13.

[0067] (2) Automatic guiding during feeding: Limit cylinder 1 41 and limit cylinder 2 42 drive guide block 1 412 and guide block 2 422 respectively. One side of the two guide blocks has a larger opening and gradually shrinks. When the cable tie 13 contacts the guide of the clamping claw (including the upper arc rod 94 and the lower arc rod 12), the two limit cylinders move outward and the guide blocks open, making it easy for the cable tie 13 to be removed smoothly.

[0068] (3) Pre-tightening the wire harness 3 before tightening the cable tie 13: The drive motor drives the worm gear 92 and the worm 91, and the upper arc rod 94 rotates downward and enters the interior of the lower arc rod 12 to pre-tighten the wire harness 3 to be tied.

[0069] (4) Automatic bundling: After the small end of the cable tie enters the cable tie hole 13 on the large end 131 of the cable tie, the servo motor 143 drives the driving gear 144 and the driven gear 147 to mesh inward, driving the extrusion wheel 145 and the extrusion wheel 2 146 to rotate inward synchronously. The extrusion wheel 145 and the extrusion wheel 2 146 are provided with pressing teeth, leaving a certain gap in the middle. When the small end of the cable tie 13 is twisted between the extrusion wheel 145 and the extrusion wheel 2 146, it is driven downward to achieve tightening.

[0070] (5) Cutting off the remaining waste: The cutting cylinder 14 pushes the movable cutter head 141 forward, and works together with the fixed cutter head 142 fixed to the housing to cut off the remaining cable tie 13.

[0071] (6) When using different automotive wiring harness 3 cable ties 13, the chuck 62 can be quickly replaced: the chuck 62 is connected to the bottom of the tooth plate 6 by a dovetail groove, and is pushed inward after installation, and the left and right sides of the chuck 62 are tightened by the shell; if replacement is required, it is only necessary to move the tooth plate 6 and push it out horizontally.

[0072] (7) When the equipment cannot be inserted into the location where bundling is required, the angle can be adjusted: when the bundling angle needs to be adjusted, the driving cylinder 125 pushes the driving gear 123 to rotate left or right, and the hanging part of the lower arc rod 12 is fixed in a circular step-like manner and can rotate with it.

[0073] With the continuous development of the automotive industry and the continuous growth of market demand, this equipment is expected to be more widely used and promoted in the future. Technological innovation: The equipment adopts advanced automatic control technology to realize the automation and intelligence of wire harness 3 bundling. By optimizing the mechanical design and material selection, the durability and service life of the equipment are improved. Design innovation: It realizes the function of universal quick change of different cable ties 13, one machine for multiple uses, and realizes the free adjustment of bundling angle, which improves flexibility. Application innovation: This equipment is not only suitable for the bundling of automotive wire harness 3, but can also be widely used in wire harness 3 bundling work in other fields. Through continuous technological upgrades and improvements, the equipment is expected to achieve more functions and better performance in the future.

[0074] With the rapid development of the new energy vehicle market, the improvement of production efficiency and quality requirements, the promotion of the trends of intelligentization and automation, the driving force of technological innovation and industrial upgrading, as well as the policy support and market demand, the automatic bundling and assembly of automotive wire harness 3 will play an increasingly important role in the new energy vehicle production line.

[0079] Under the action of the first micro-motor 101, the first rotating shaft 102 rotates, and then drives the first rotating rod 103 to rotate.

[0080] In this solution, the second rotating rod assembly 11 is designed. On the one hand, it can lift the bundled wire harness 3. That is, when the first rotating rod 103 and the second rotating rod 113 rotate simultaneously, from Figure 11 From the perspective of observation, both the first rotating rod 103 and the second rotating rod 113 rotate clockwise. The wire harness 3 rises under the arching action of the two, so that the tie head 131 rises. Subsequently, the wire harness 3 moves, and the large head of the tie strap 131 disengages from above the outer shell 1.

[0081] It should be noted that the movement of the wire harness 3 is carried out under the action of a driving and moving mechanism, which can be an upper rotating roller and a lower rotating roller, between which the wire harness 3 is located, and driven to move under the rotation of the upper rotating roller and the lower rotating roller; it can also be a horizontally moving manipulator, which moves the wire harness 3 forward under the grasping movement of the manipulator; the driving and moving mechanism is a prior art and is not limited to the above-mentioned structure, as long as it can move the wire harness 3 forward, it will not be described in detail here.

[0082] The cut big end 131 of the cable tie is separated from the shell structure, and the wire harness 3 moves forward for the next round of binding. On the other hand, an air pipe 114, an air duct and an air pump are provided. Under the action of the air pump, air is ventilated into the air pipe 114 and sprayed from the side of the vertical portion 115 toward the side of the cable tie 13 and the inner side of the upper arc groove 95. Under the action of wind force, the cable tie 13 is ensured to be tightly attached to the upper arc groove 95, thereby ensuring that the small end of the cable tie is accurately inserted into the big end 131 of the cable tie, thereby ensuring the stability of the work. It should be noted that the spray direction of the airflow is not toward the small end of the cable tie, otherwise it will definitely cause the small end of the cable tie to bend.

[0083] A rotating rod assembly 10 is provided, which cooperates with the rotating rod assembly 2 11. The upward rotation of the rotating rod 103 and the rotating rod 2 113 causes the wire harness 3 to rise under the support of the two, so that the cut large end 131 of the cable tie is separated from the shell structure, so that the next round of binding action can be carried out smoothly.

[0084] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
