[0032] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] In this document, "plurality" refers to two or more. "And / or" describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates an "or" relationship between the associated objects.

[0034] Example 1

[0035] Please refer to Figure 1 , which shows a schematic diagram of the structure of an electronic drawing board imaging system provided by an exemplary embodiment of the present application. An electronic drawing board imaging system is used in the production process of a cable harness, comprising:

[0036] An electronic drawing board storage unit, used for storing a two-dimensional electronic drawing of a cable harness drawing board;

[0037] A luminous material printing device for printing using luminous materials according to a stored two-dimensional electronic drawing;

[0038] A projection unit including a plane wave light source is used to project the printed cable harness drawing board onto a workbench through a laser light source or an LED array light source to form a clear drawing board image;

[0039] Drawing management module is used to digitally manage and update the versions of two-dimensional electronic drawings.

[0040] In one possible implementation, the cable harness drawings (e.g., CAD design files) are stored in electronic formats (such as PDF, SVG, etc.) by uploading files or reading with a scanner, and are saved in the system's database for easy subsequent management and retrieval. Photoelectric materials or fluorescent inks are used for printing, and the design drawings are printed into cable harness drawing boards. The drawing board can effectively improve visibility in low-light environments and avoid affecting operational accuracy due to changes in ambient light. The projection system uses a laser light source or an LED array light source to project the drawing board onto the workbench. The light source uses a laser or LED array light source to provide a uniform, high-contrast projection effect, allowing technicians to operate accurately according to the drawings. The drawing management module includes drawing version management and real-time update functions to ensure that each workstation uses the latest version of the drawing to avoid operational errors caused by version confusion.

[0041] Among them, the electronic drawing board storage unit adopts standardized file format storage, supports file conversion and automatic classification, and ensures the reliability and traceability of data.

[0042] The luminous material printing device uses fluorescent ink and photoelectric materials, which have high brightness and durability, ensuring that the board can be clearly displayed under different lighting conditions.

[0043] The power, angle and intensity of the light source of the projection unit are precisely adjusted to ensure the clarity and operability of the drawing board image in different working environments.

[0044] The drawing management module supports automatic updating and synchronization, ensuring that each workstation uses the latest version of electronic drawings to avoid inconsistent drawing versions.

[0045] As can be seen, in the embodiments of this application, the system can save manual operation time, reduce the workload of traditional manual drawing board laying, and improve work efficiency and accuracy through precise electronic drawing management. The use of high-brightness luminous materials makes the drawing board clearly visible even in low-light environments, reducing errors caused by environmental factors. The projection system ensures the clarity of the drawing image through high-quality light sources, avoiding the distortion caused by damage or contamination of traditional drawings.

[0046] Example 2

[0047] Optionally, the luminescent material used in the luminescent material printing device is fluorescent ink, photoelectric material or other materials that can provide high contrast display in low light environment, and the luminous intensity of the luminescent material is 300cd / m 2 Up to 1000cd / m 2 The spectral range includes 480nm to 580nm in the visible light region.

[0048] Among them, the luminous intensity is 300cd / m 2 Up to 1000cd / m 2 The visible spectrum, which spans 480nm to 580nm, ensures clarity and contrast under all lighting conditions. Fluorescent ink is highly durable and stable, and will not fade or lose its brilliance over extended use.

[0049] Therefore, the choice of fluorescent ink can maintain the clarity of the drawing board in a variety of ambient lighting conditions, improving the operator's work precision. The high luminous intensity ensures that the drawing board is still clearly visible in dark environments, avoiding the misoperation caused by insufficient light in traditional drawing boards.

[0050] Example 3

[0051] Optionally, the plane wave light source is a laser light source or an LED array light source with a wavelength range of 400nm to 700nm and an irradiation angle of 30° to 60°.

[0052] The 400nm to 700nm wavelength spectrum covers the visible light region, ensuring that the image on the drawing board accurately reflects the drawing content. The illumination angle is set between 30° and 60°, ensuring that the light source evenly illuminates the entire drawing surface, avoiding partial overexposure or dimming. The illumination intensity can be adjusted to suit different environments, ensuring high-contrast images in various lighting conditions.

[0053] This demonstrates that through precise control of wavelength and illumination angle, the projection system ensures high contrast and uniformity of the drawing image, improving work accuracy. Adjustable illumination intensity ensures clear images of drawings in various working environments, enhancing the system's adaptability.

[0054] Example 4

[0055] Optionally, the drawing management module includes image recognition, data processing and format conversion functions. After the two-dimensional electronic drawings are input into the system through file uploading, scanner reading or other methods, they are digitized.

[0056] The system's drawing management module includes an image recognition and data processing unit. Once a technician uploads a cable harness drawing into the system, the system automatically converts the drawing to supported formats, including PDF and SVG. The system also links the drawing to production information, ensuring each drawing version matches the production batch.

[0057] Drawings can be entered into the system through file uploads, scanner reading, and other methods, supporting a variety of file formats. Advanced OCR (Optical Character Recognition) technology automatically extracts key information from drawings, converts them into different formats, and stores them. Furthermore, the system supports drawing version management and updates, ensuring that the latest drawings are used in production.

[0058] The integrated drawing management module ensures consistent drawing versions, avoiding the errors and confusion associated with traditional manual management. Real-time updates and version control make the production process more efficient and reduce operational errors caused by drawing version issues.

[0059] Example 5

[0060] Optionally, the system also includes an image quality control device for optimizing the resolution of the drawing board image and automatically adjusting the contrast and clarity of the drawing board image.

[0061] The system includes an automatic image quality control device that adjusts the brightness, contrast and clarity of the drawing board image in real time according to changes in ambient light, ensuring that technicians can obtain clear and accurate drawing images in any situation.

[0062] The system automatically monitors the brightness and contrast of the projected image and makes real-time adjustments when anomalies are detected to avoid affecting operational accuracy. Integrated light sensors allow the system to sense changes in ambient lighting and automatically adjust the image display.

[0063] Automatically adjusting image quality ensures the image on the board remains optimal, ensuring the best display quality in varying lighting conditions. By optimizing the quality of the projected image, operational accuracy and efficiency are greatly improved.

[0064] Example 6

[0065] Please refer to Figure 2 , which shows a flow chart of an operating method of an electronic drawing board imaging system provided by an exemplary embodiment of the present application. This embodiment is described using the method as an example of the electronic drawing board imaging system provided by the above embodiment. The method includes:

[0066] Step 201: storing a two-dimensional electronic drawing of a cable harness drawing board in an electronic drawing board imaging system.

[0067] The two-dimensional electronic drawing format of the cable harness drawing board is converted into a standard format that can be displayed in the electronic drawing board imaging system; the two-dimensional electronic drawing after format conversion is stored in the system database.

[0068] In one possible implementation, all 2D electronic drawings are input into the system via file upload or scanner reading. The system then uses image recognition and data processing modules to convert the input drawings into a standard format suitable for display on the electronic drawing board imaging system, such as SVG or PDF.

[0069] All drawings will be converted to support formats such as SVG and PDF to ensure that the drawings can be recognized and displayed by the system. The converted drawings are stored in a standardized format for easy version control and retrieval.

[0070] This shows that format conversion ensures that drawings from different sources can be displayed smoothly in the system, improving system compatibility. Standardized storage facilitates unified management and updating of drawings.

[0071] Step 202: Print the stored two-dimensional electronic drawing into a corresponding cable harness drawing board using a luminous material printing device;

[0072] Step 203 , projecting the printed cable harness drawing board onto a workbench by a projection unit including a plane wave light source to form a clear drawing board image;

[0073] Step 204: Update and manage the two-dimensional electronic drawings in real time according to production requirements.

[0074] During the cable harness production process, the cable harness drawings are first stored in the system database. A luminous material printing device then prints the drawing board. Once printed, the system uses an LED array light source to project the board image onto the workbench, allowing technicians to assemble the cable harness based on the projected image. The system manages drawing versions in real time to ensure the latest drawings are used.

[0075] In one possible implementation, the drawings are stored in the system through file upload and format conversion is performed; the drawings are printed using luminous materials to ensure that the drawing board is clearly visible in low-light environments; and the drawings are projected using high-quality light sources to ensure that technicians can accurately refer to the drawings for operation.

[0076] This demonstrates that digital management and automated printing significantly reduce the complexity and errors of manual operations, improving production efficiency. Real-time drawing management ensures technicians always use the latest drawings, avoiding production errors caused by outdated versions.

[0077] Optionally, the method further includes:

[0078] The alignment and clarity of the board image are automatically detected through image recognition technology; if there is any deviation, the position and size of the board image are automatically adjusted.

[0079] During the drawing projection process, the system automatically detects the alignment and clarity of the drawing image through cameras and image recognition technology. If any deviation is found, the size and position of the drawing image will be automatically adjusted to ensure precise alignment.

[0080] The camera monitors the drawing image in real time and automatically detects deviations. When deviations are detected, the system automatically adjusts the position and size of the drawing image. This automatic adjustment function ensures precise alignment of the drawing image, improving operational accuracy and efficiency. Image recognition and automatic adjustment reduce the complexity and errors of manual operations, further improving production efficiency.

[0081] An embodiment of the present application also provides a computer-readable medium, which stores at least one instruction, and the at least one instruction is loaded and executed by the processor to implement the electronic drawing board imaging system operation method described in the above embodiments.

[0082] The above description is merely an optional embodiment of the present application and is not intended to limit the present application.
