Description

Technical Field

[0001] The present invention relates to the technical field of wire harness forming, and in particular to a combined wire harness forming process guiding method. Background Art

[0002] Wire harnesses (also known as wire ties) are widely used in assembly-level electrical products to deliver power, transmit control signals, and send and receive data. As the bridge connecting various components (connectors, relays, circuit breakers, position meters, pushbutton switches, terminal blocks, etc.), the quality of the wire harness directly impacts the production quality of assembly-level electrical products.

[0003] Generally speaking, a single wiring harness product is composed of wires of various specifications and protective materials, and has a shape similar to a multi-branched tree, where: the number of wires ranges from dozens to hundreds, and the length ranges from tens of centimeters to about two meters; protective materials include polytetrafluoroethylene film, nylon braided sleeves, wire protection tubes, corrugated tubes, etc., which are used to protect the wiring harness from wear or cutting in the working environment.

[0004] In the prior art, in the production process of assembly-level electrical products, there are two main ways to guide the wiring harness product molding process. One is the template (or tooling) wiring method, that is, drawing a template or making tooling at a 1:1 ratio according to the design or process construction drawing, and then wiring directly on the template (or tooling); the other is the drawing-based binding method, that is, binding the wires according to the binding direction and the order of wire continuation and wire shedding specified in the process regulations, combined with the wire harness segment size marked on the drawing. Compared with the template wiring method, the drawing-based binding method requires higher operating skills of the production personnel, and is prone to problems such as inconsistent branch lengths and missing wires, and the molding process is time-consuming. Therefore, when facing large-scale production, the template wiring method is mainly used to complete the molding and production of the wire harness. When using the template wiring method to guide wire harness forming, there are three problems: the routing path of each wire needs to be found on the wiring diagram, which is time-consuming and labor-intensive; the wires are laid on top of the template diagram, and as the number of wires increases, the laid wires can easily block the routing path information on the diagram, affecting subsequent operations; the wiring harness protection requirements and wire number inspection requirements are unclear, which is not conducive to operators' understanding and implementation.

[0005] In summary, there is at least one of the following technical problems:

[0006] The routing path of each wire needs to be found on the wiring diagram, which is a time-consuming and labor-intensive process;

[0007] Wires are laid on top of the template. As the number of wires increases, the laid wires can easily block the routing information on the pattern, affecting subsequent operations.

[0008] The wiring harness protection requirements and wire number inspection requirements are not clearly indicated, which is not conducive to operators' understanding and implementation. Summary of the Invention

[0009] The main purpose of the present invention is to provide a combined wire harness forming process guidance method and its use method, so as to solve at least one technical problem in the prior art that the routing path of each wire needs to be found on the wire binding diagram, which is a time-consuming and labor-intensive process; the wires are laid on top of the template diagram, and as the number of wires increases, the laid wires can easily block the routing path information on the pattern, affecting subsequent operations; the wire harness protection requirements and wire number inspection requirements are not clearly indicated, which is not conducive to the operator's understanding and execution.

[0047] In this embodiment, the virtual-reality fusion guidance of the wire harness 1 forming process includes the visual definition of the wire clamp 2 layout process, the visual definition of the wire routing process, the visual definition of the wire number inspection process, and the visual definition of the wire harness 1 protection process. The visual definition of the wire clamp 2 layout process is achieved by constructing a wire clamp 2 resource database, defining the wire clamp 2 layout orientation based on the routing path, and automatically generating layout instructions based on the wire clamp 2 information. The visual definition of the wire routing process is achieved by drawing the wire routing path based on design parameters, presenting the wire routing process based on a segmented display, and compiling routing step instructions based on wire information, thereby improving the readability and guidance of the wire routing process. The visual definition of the wire number inspection process is achieved by defining the wire number inspection area based on a rectangular wireframe, automatically identifying the wire number based on the inspection area, automatically arranging the wire number sequence based on rules, and automatically generating inspection instructions based on the wire number information. This improves the readability and guidance of the wire harness 1 inspection process.

The harness 1 forming process is visually defined through a virtual-real fusion guidance process. After completing the visual editing of the harness 1 product forming process, the visual process elements are gradually and accurately overlaid on the real-world image of the wiring area captured by a real camera, according to the process flow. This visual presentation of the harness 1 product forming process in a virtual-real fusion scenario guides the operator through the harness 1 forming operation. This virtual-real fusion guidance process includes: completing real-world camera calibration in a real-world wiring scenario to determine the camera's internal and external parameters; placing a two-dimensional marker code at the center of the harness 1 forming area on a real wiring board; using a real-world camera placed directly above the center of the wiring board to capture the two-dimensional marker code; and using computer vision algorithms to determine the spatial positional relationship between the real-world camera and the two-dimensional marker code.

[0049] In this embodiment, the virtual-real fusion guidance of the wiring harness 1 forming process also includes: in the virtual wiring scene, according to the spatial position relationship between the two-dimensional marker code and the real camera in the real scene, setting the virtual camera position, so that the posture relationship between the virtual camera and the center of the virtual wiring board is exactly the same as the posture relationship between the real camera and the two-dimensional marker code, thereby completing the precise registration of the virtual-real wiring scene. The virtual-real fusion guidance of the wiring harness 1 forming process also includes: relying on the virtual camera to obtain a virtual image of the wiring harness 1 forming process; relying on the real camera to obtain a real-time real image of the wiring scene; attaching the virtual image of the wiring harness 1 forming process to the real-time real image of the wiring scene to achieve the superposition of the virtual and real wiring scene images; according to the planned process flow, facing the wire clamp 2 arrangement, wire routing, wire number inspection, and wiring harness 1 protection process, the virtual-real fusion image is displayed step by step to guide the operator to complete the wiring harness 1 forming work.
