Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, in particular to a wire harness feeding device with fracture detection function. Background Art

[0002] Wire harnesses are key components in electronic circuit product systems. They are typically assembled from multiple wire harness units, available in various lengths and types. Wire harness production involves cutting raw wires of varying sizes and colors to length before assembling them. These raw wires are typically wound onto reels, which are then mounted on a feed drum for continuous, rotating feeding.

[0003] In addition to single, continuous wire harness coils, wire harness reels also exist, made by splicing multiple individual wire harnesses together. While these types of reels offer relatively low raw material costs, they leave gaps at the splices, rendering the wires unusable and requiring operators to identify and remove them. However, these reels are often densely packed, making it easy for operators to miss or misidentify wires. Therefore, further improvements are needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a wire harness feeding device with fracture detection.

[0005] An embodiment of the present invention solves the technical problem by adopting a technical solution: a wire harness feeding device with fracture detection, comprising: a workbench, a control center, and a barrel mounting assembly, a feeding assembly, a fracture detection assembly, and a cutting assembly arranged on the workbench;

[0006] The barrel mounting assembly is used to install the wire harness roll; the feeding assembly includes a pressure wheel and a feed roller; the pressure wheel can press the wire harness toward the feed roller and feed the wire harness forward; the fracture detection assembly includes a proximity switch, which can detect metal products passing through the proximity switch and feedback signals to the control center; the cutting assembly can cut the wire harness.

[0007] Optionally, the proximity switch is an annular proximity switch having an annular channel.

[0008] Optionally, two proximity switches are provided at intervals in front and back along the wire harness feeding direction.

[0009] Optionally, the fracture detection component is provided with a long strip-shaped detection channel, and the two proximity switches are provided at opposite ends of the detection channel.

[0010] Optionally, support blocks are further provided at the front and rear ends of the detection channel.

[0012] Optionally, the workbench is further provided with a material picking assembly, which is arranged at the rear end of the cutting assembly; the material picking assembly is provided with a lateral push rod, which can push the wire harness sideways.

[0013] The beneficial effects of this utility model are as follows: the metal proximity switch can be used to detect metal products passing through the proximity switch and feedback signals to the control center. If a connection break occurs during the continuous feeding of the wire harness roll, the break is not wrapped with a protective layer, and the metal core is exposed. This can be detected by the metal proximity switch. The control center determines the length of the connection break based on the feeding speed and the break detection time, and then controls the cutting component to cut the material at the break. The machine can also be stopped to prompt the operator to select the cut material.

[0023] Example

[0024] Reference Figure 1 The present invention proposes a wire harness feeding device with fracture detection, comprising: a workbench 10, a control center, and a barrel mounting assembly 20, a feeding assembly 30, a fracture detection assembly 40, and a cutting assembly 50 arranged on the workbench 10;

[0025] The barrel mounting assembly 20 is used to install the wire harness reel; the feeding assembly 30 includes a pressure wheel 31 and a feeding roller 32; the pressure wheel 31 can press the wire harness toward the feeding roller 32 and feed the wire harness forward; the fracture detection assembly 40 includes a proximity switch 41, which can detect metal products passing through the proximity switch 41 and feedback signals to the control center; the cutting assembly 50 can cut the wire harness.

[0026] In the present invention, the metal proximity switch 41 can be used to detect metal products passing through it and feedback a signal to the control center. If a connection break occurs during the continuous feeding of the wire harness reel, where the protective rubber layer is missing and the metal core is exposed, the metal proximity switch 41 will detect the presence of the connection break. The control center determines the length of the connection break based on the feeding speed and the break detection time, thereby controlling the cutting assembly 50 to cut the material at the break, and can also stop the machine to prompt the operator to select the cut material.

[0027] In this embodiment, in order to facilitate the passage of the wire harness and uniformly detect defective products with gaps in the interface or protective layer from a circumferential direction, the proximity switch 41 is an annular proximity switch 41 with an annular channel.

[0028] In this embodiment, in order to improve the accuracy of detection and reduce misjudgment and incorrect judgment of the break length, two proximity switches 41 are arranged at intervals along the feeding direction of the wire harness to perform two metal exposure detections on the wire harness.

[0029] In this embodiment, in order to facilitate the installation of two proximity switches 41 , the fracture detection assembly 40 is provided with a long strip-shaped detection channel 42 , and the two proximity switches 41 are provided at opposite ends of the detection channel 42 .

[0030] Furthermore, support blocks 43 are provided at the front and rear ends of the detection channel 42, which can lift and support the wiring harness at the front and rear ends of the detection channel 42 to prevent the wiring harness from falling due to gravity and directly touching the contact switch, thereby causing wear and affecting the contact switch.

[0031] In this embodiment, two feeding assemblies 30 are provided, which are located at the front and rear ends of the workbench 10. The wire harness after cutting can be fed forward to the semi-finished product area or the next station.

[0032] In this embodiment, in order to facilitate the direct cutting and picking out of defective wire harnesses or wire harnesses at the port interface, the workbench 10 is also provided with a material picking component 60, which is arranged at the rear end of the cutting component 50; the material picking component 60 is provided with a lateral push rod 61, which can push the wire harness sideways.

[0033] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
