Description

Technical Field

[0001] The present invention relates to the field of strapping machinery, and in particular to a manual device for identifying a strapping harness; Background Art

[0002] During the automobile assembly process, it is usually necessary to install control cables, connecting cables and other wiring harnesses. In order to distinguish different types of wiring harnesses and to clearly identify their fixing points with automobile assembly parts, adhesive identification tapes are usually tied around the periphery of these wiring harnesses. At present, the binding of adhesive identification tapes mainly relies on manual operation, but this method has the problem of low production efficiency, and in order to ensure that the identification tape is firm, the adhesive identification tape is usually required to be tied more than 1.5 times. However, when manually tied, the identification tape often shifts, and it cannot be guaranteed that each turn accurately surrounds the same binding center, resulting in misalignment of the identification tape, which not only affects the assembly quality, but also reduces the overall aesthetics of the product. CN112706971B discloses a wire harness tape binding device, which includes a support frame, a conveying device, a first driving wheel, and a tape binding mechanism. The tape passes through the conveying device and is installed at the bottom of the narrow slot of the first driving wheel. The first driving wheel drives the tape to be wound around the wire harness by rotating. The structure of this device is complex, and the tape is easily adhered to the device during the process of being conveyed by the conveying device and pushed to the bottom of the narrow slot of the first driving wheel, resulting in a high failure rate. In addition, when the tape breaks in the device and winds itself up, it is not easy to remove the faulty tape, resulting in a decrease in production efficiency. Summary of the invention
