Technical Field

[0002] In the production and processing of automotive wiring harnesses, the method of winding the lines together to form a wiring harness is generally adopted. The reason for adopting such a processing method is mainly because it can make many lines more regular and orderly. When the lines are integrated into wiring harnesses in this winding form, on the one hand, during the assembly process of automotive wiring harnesses, installers can install the wiring harnesses more conveniently, greatly improving the installation efficiency of the wiring harnesses. On the other hand, in the subsequent maintenance stage of automotive wiring harnesses, it is also convenient for maintenance personnel to quickly and accurately find specific lines for inspection and maintenance, providing strong guarantees for the normal production and processing of automotive wiring harnesses.

[0003] In the production and processing of automotive wiring harnesses, when using automated winding equipment to wind the lines into wiring harnesses, the overall diameter of the wiring harness often changes due to the presence of branches in some parts of the wiring harness, causing the wound wiring harness to easily break, or even the wiring harness to explode when the finished product is wound, forcing the automated winding equipment to stop and stop winding, affecting the continuity of automotive wiring harness production and processing, and making it difficult to meet the needs of efficient production. At present, workers usually use tape to manually wind to solve the problem of wire harness cracking or even explosion. However, this method of manually re-winding the tape on the broken position during the production process of the wiring harness can maintain production in an emergency, but the overall efficiency is low, which greatly affects the overall production progress and efficiency of the automotive wiring harness.

[0027] 3. After placing the wiring harness inside the annular block, when re-wrapping the tape on the position where the tape on the surface of the wiring harness is cracked or even exploded, the electric push rod pushes the arc frame upward, so that the upper ends of the two groups of first connecting rods above are tilted outward, and the connecting piece drags the rack to move outward. The two racks drive the gears meshing with them to rotate inward, and the second connecting rod is flipped inward through the rotating shaft. At this time, the two mounting frames remain horizontal and close to each other. Afterwards, the inner power-assisting roller clamps the wiring harness, and the driving motor drives the power-assisting roller to rotate through the connecting shaft. The two power-assisting rollers rotate in opposite directions, and can push and pull the rotating assembly and the film assembly along the wiring harness. The moving speed is stable, and there is no need to completely manually control the movement of the device. This not only improves the convenience of use, but also improves the neatness of the film winding on the surface of the wiring harness. BRIEF DESCRIPTION OF THE DRAWINGS

The rear surface of the annular block 201 is symmetrically provided with mounting holes 208, and the top of the annular block 201 is provided with a second line inlet 209. The two film assemblies 3 each include a mounting rod 301, and the rear ends of the two mounting rods 301 are respectively threadedly connected to the inner surface walls of the two mounting holes 208.

The plurality of guide wheels 202 are rotatably mounted on the front surface of the rear shell 1, and the outer surface of the guide wheel 202 is slidably fitted with the outer surface of the annular block 201, and the outer surfaces of the two guide pulleys 203 are slidably fitted with the outer surface of the annular block 201 and are rotatably mounted on the front surface of the rear shell 1, and the outer surface of the extrusion guide wheel 204 is slidably fitted with the outer surface of the annular block 201 and is rotatably mounted on the front surface of the rear shell 1, and the transmission connection between the extrusion guide wheel 204, the driving pulley 205 and the outer surfaces of the two guide pulleys 203 A transmission belt 207 is connected, and the servo motor 206 is fixedly installed on the front surface of the front cover 12, and the output end rotates through the front cover 12 and is fixedly connected to the center of the front surface of the driving pulley 205. Handle plates 13 are installed on the outer surfaces of the opposite sides of the front cover 12 and the extension shell 11 near the bottom. Circular openings 14 are opened on the outer surfaces of the front cover 12 and the rear shell 1 near the top, and a first wire inlet 15 is opened on the top of the circular opening 14.

It is not necessary to completely rely on the hand to control the movement of the device, which improves the convenience of use and the neatness of the film winding on the surface of the wire harness. This design also avoids the phenomenon that the centrifugal force during the rotation of the film rack 306 makes it difficult to hold the device stably when the manual hand moves it. At the same time, when the wire harness is squeezed too tightly by the two assisting rollers 516, a reaction force will be generated to push the assisting rollers 516 outward. When the first extension frame 511 and the second extension frame 512 are moved outward, the first extension frame 511 and the second extension frame 512 will respectively drive the corresponding U-shaped frame 510 to move outward. During the process, the slide bar 507 limits the U-shaped frame 510, ensuring the stability of the assisting roller 516 during the movement. When the U-shaped frame 510 moves outward, it squeezes the spring 508 and generates an inward squeezing force, so that the two assisting rollers 516 can effectively adhere to the surface of the line without squeezing the line. When the two assisting rollers 516 are close to each other, the extension sheet 513 on the surface of the first extension frame 511 will be inserted into the inner groove 514 on the surface of the second extension frame 512, so that the wiring harness is confined in a closed space and effectively fits with the assisting roller 516, ensuring the effect produced when the assisting roller 516 rotates.

[0037] The use method and working principle of the device: During the production and processing of automobile wiring harnesses, when part of the tape breaks or even explodes after the line is wound into a wiring harness using an automated winding device, at this time, the worker uses the device to first insert the wiring harness with the surface tape broken or even exploded from the first wire inlet 15 and the second wire inlet 209 into the inner side of the annular block 201, and then controls the end of the device close to the circular opening 14 to move on the wiring harness path by holding the handle. During this process, the servo motor 206 is started to drive the drive pulley 205 to rotate. At this time, the transmission belt 207 will rotate between the extrusion guide wheel 204, the drive pulley 205 and the outside of the two guide pulleys 203, and because the annular block 201 is driven by the guide wheels 202, The guide pulley 203 and the extrusion guide wheel 204 are suspended and limited, and the annular block 201 and the transmission belt 207 are in close contact with each other. Therefore, the friction force of the transmission belt 207 during its movement will drive the annular block 201 to rotate, and then drive the two film assemblies 3 at the rear to rotate around the outer side of the gathered line. In this process, the film is pulled off the film rack 306 and wrapped on the line surface, so as to restore the wound part of the wire harness that is cracked or even exploded on the surface. The overall size of the device is small and the structure is compact. When workers use the device to wrap adhesive tape around the wire harness that is cracked or even exploded during the production and processing of automobile wire harnesses, they only need to feed the wire harness into the inner side of the annular block 201, and then hold the device and move along the wire harness to quickly complete the winding operation. The production can be maintained in an emergency, and the overall tape winding efficiency is high, which ensures the overall production progress and efficiency of the automobile wiring harness. At the same time, the device is small in size and can perform tape winding operations on the automobile wiring harness in a small space, which is convenient for tape winding maintenance of the wiring harness installed in the small space of the car later. The function is relatively practical. When the device is used to wind the film on the surface of the installed wiring harness, two reasonably arranged film racks 306 can be installed with insulating tape and aluminum foil tape respectively. During the winding process, the insulating tape and aluminum foil tape can be wound on the surface of the wiring harness in layers for fixing at the same time, and the aluminum foil material has the performance of shielding signal interference. The aluminum foil tape can also be replaced with other functional tapes according to actual conditions, thereby meeting the needs of the wiring harness. The invention can meet the production, processing and use requirements of different wiring harnesses, further improve the auxiliary effect of the device for wiring harness installation, and has good practicality. Moreover, when assembling the common film on the market with the device, it is only necessary to loosen the anti-skid nut 305 and remove the conical second extrusion block 304 from the mounting rod 301, and then put the film with different inner diameters or the film with the film holder 306 on the outside of the mounting rod 301, and then reinstall the second extrusion block 304 on the surface of the mounting rod 301 through the anti-skid nut 305. At this time, the two conical first extrusion blocks 302 and the second extrusion blocks 304 can fix the film by friction, and the conical extrusion blocks can fix the common film on the market, and no special customized products are required, so the versatility is high.Thereby, the auxiliary effect of the device on the installation of automobile wiring harness is further improved. Moreover, after the wiring harness is placed inside the annular block 201, when the adhesive tape on the surface of the wiring harness is cracked or even exploded, the electric push rod 403 is started to push the arc frame 401 upward. At this time, the arc frame 401 will push the two sets of first connecting rods 405 above upward, so that the upper ends of the slightly inclined first connecting rods 405 move outward and tilt. At this time, the connecting piece 406 will drag the rack 407 outward. When the two racks 407 move outward synchronously, they will drive the two gears 504 meshing with them to rotate inward. The second connecting rod 502 is driven to turn inwards through the rotating shaft 503 connected to the gear 504, and the second connecting rod 502, the first rotating seat 501 and the second rotating seat 505 added on the outside play the role of limiting the mounting frame 506. Therefore, when the electric push rod 403 is started to drive the second connecting rod 502 to turn inwards, the two mounting frames 506 can be driven to maintain a horizontal state and approach each other. After the two mounting frames 506 are close to each other, the two assisting rollers 516 on the inside will clamp the scattered wire harnesses, and then the driving motor 517 is started to drive the two assisting rollers 516 through the connecting shaft 515. The two power-assisting rollers 516 rotate closely against the wiring harness, and the two power-assisting rollers 516 rotate in opposite directions. According to the direction of rotation, the rotation assembly 2 and the film assembly 3 can be pushed and pulled to move along the outside of the wiring harness, and the moving speed is relatively stable. It is not necessary to completely rely on the hand to control the movement of the device, which improves the convenience of use and the neatness of the film winding on the wiring harness surface. At the same time, when the wiring harness is squeezed too tightly by the two power-assisting rollers 516, a reaction force will be generated to push the power-assisting rollers 516 outward. At this time, the first extension frame 511 and the second extension frame 512 will respectively drive the corresponding U-shaped frame 510 to move outward. During the process The slide bar 507 serves to limit the U-shaped frame 510, ensuring the stability of the assist roller 516 during its movement. When the U-shaped frame 510 moves outward, it squeezes the spring 508 and generates an inward squeezing force, so that the two assist rollers 516 can effectively adhere to the line surface without squeezing the line. When the two assist rollers 516 are close to each other, the extension piece 513 on the surface of the first extension frame 511 will be inserted into the inner groove 514 on the surface of the second extension frame 512, so that the wire harness is confined in a closed space and effectively fits with the assist roller 516, ensuring the effect produced when the assist roller 516 rotates.
