Description

Smart tool cart Technical Field

[0001] This utility model relates to the field of tool cart technology, and more specifically to the field of intelligent equipment technology based on an intelligent workshop management system. Background Technology

[0002] In today's booming manufacturing industry, digital intelligent control cabinet workshops are gradually becoming the core locations for producing non-standard control cabinets. However, in actual production operations, a series of problems faced by operators are becoming increasingly prominent, seriously restricting the efficiency and accuracy of production.

[0003] On the one hand, the coordinated use of tools and drawings is crucial for ensuring processing quality and efficiency. However, the current lag in the drawing update mechanism acts as a significant obstacle between operators and efficient production. During processing, operators often need to perform precise operations based on drawings, but the lack of timely updates causes discrepancies between the drawings they refer to and the actual production requirements. This not only leads to frequent errors in the processing, resulting in a high rework rate for control panels, but also significantly wastes the overall manpower. Operators are often bogged down in the tedious process of repeatedly checking drawings and modifying processing steps, with valuable time constantly slipping away in inefficient repetitive operations, severely hindering the overall production progress of the workshop.

[0004] On the other hand, the paper-based drawing management model has numerous drawbacks. Firstly, there's the issue of resource waste. The large volume of drawing printing demands consumes a considerable amount of paper resources, which is particularly inappropriate in today's increasingly environmentally conscious world. With increased usage frequency, wear and tear on the drawings is inevitable. Once the drawings are worn, the detailed information becomes blurred, which not only affects operators' accurate grasp of processing parameters but may also lead to processing errors caused by misunderstandings of the drawings, further impacting the quality and performance of the control panels. Furthermore, managing paper drawings is equally troublesome. Quickly and accurately finding the required drawing among numerous others is an extremely challenging task, often requiring significant manpower and time. Moreover, issues such as the storage, organization, and version control of drawings place a heavy burden on the daily management of the workshop, seriously affecting its operational efficiency and management level.

[0005] In conclusion, resolving the issues related to drawing updates and management in digital intelligent panel cabinet workshops has become an urgent priority for improving workshop production efficiency, ensuring product quality, reducing resource waste, and optimizing tool management. Only by overcoming this challenge can digital intelligent panel cabinet workshops truly achieve intelligent and efficient production, thereby gaining a favorable position in fierce market competition and driving the entire non-standard processing panel cabinet industry towards higher quality and greater sustainability.

[0057] Implementation Method Two: This implementation method is described in conjunction with Figure 5. This implementation method provides a detailed explanation of the functions implemented by the intelligent tool vehicle proposed in Implementation Method One above.

[0058] As shown in Figure 5, the intelligent tool cart achieves automatic updates of received drawings through the interconnection and cooperation of various hardware modules. Specifically, the communication module is responsible for data transmission, the memory is responsible for version management, and the touch screen provides the interactive interface. No program modification is required throughout the process, and the parts involving the program can be implemented using existing programs.

[0059] Specifically, the workshop management system pushes new drawings (such as DWG format files) to the intelligent communication module via the HTTP protocol. The intelligent communication module stores the drawings in the storage unit (SSD) and overwrites the old version (based on the existing file overwrite function) to realize the drawing reception function. Operators view the drawings through the touch screen. If modifications are needed, they click the "Approval Request" button. The communication module calls the existing OA interface of the workshop management system (such as the WeChat Approval API) to submit the application. After approval, the workshop management system automatically pushes the updated file to the tool cart to realize the drawing display and approval functions.

[0060] This implementation method achieves online display and automatic updating of drawings through the physical connection and data synchronization of the aforementioned modules, completely replacing paper drawings. Operators can directly view the latest version via touchscreen, reducing rework caused by drawing errors and decreasing wasted time by approximately 40%.

[0061] Furthermore, the intelligent tool cart achieves tool loss prevention management through the interconnection and collaboration of various hardware modules. Specifically, the camera provides physical status data, and the programmable logic controller (PLC) and central processing unit (CPU) perform logical judgments, all of which are combinations of existing module functions.

[0062] Specifically: Tool matching and prompts: The central processing unit (CPU) reads the current drawing from the storage unit, calls the tool database pre-stored in the SSD, and displays a list of required tools on the touchscreen (e.g., "M6 wrench required"). Tool access monitoring: When the operator opens the compartment, the position sensor detects the tool's presence, and the data is transmitted to the CPU via the programmable logic controller (PLC); the camera captures an image of the tool, and the built-in OpenCV library is used to compare the contours to confirm whether the tool type matches; if the tool is not returned or the type is incorrect, the CPU triggers an audible and visual alarm.

[0063] The tool storage and retrieval status of the intelligent tool cart is verified by both cameras and sensors. In case of abnormalities, an audible and visual alarm provides real-time alerts, reducing tool loss rates by over 60%. Operators can retrieve tools according to on-screen prompts, and a video detection unit verifies tool compatibility, reducing processing error rates by 35% and improving tool scheduling efficiency by 50%.

[0064] Furthermore, the intelligent tool cart's tool compartment opening and closing is also achieved through the interconnection and collaboration of various hardware modules. Specifically: Tool Retrieval: The operator selects a tool via the touchscreen. The central processing unit (CPU) sends an unlocking command to the programmable logic controller (PLC). The PLC controls the electromagnetic lock of the corresponding compartment to open. After the position sensor detects that the tool has been removed, the PLC sends a status feedback to the CPU. Tool Return: When a tool is returned to its compartment, the position sensor detects a position signal. The camera captures an image and compares it with the tool type. After confirmation, the PLC controls the electromagnetic lock to close.

[0065] In the above description, all hardware modules involved in this utility model are commercially available products, specifically including: PLC: Siemens S7-1200, supporting industrial automation control; Camera: Hikvision DS-2CD3320D-I, with built-in image acquisition and OpenCV library; Intelligent communication module: Quectel EC25, supporting 4G / Wi-Fi communication; Sensor: Omron E2E-X5ME1, used for position detection; Alarm: Omron F3SJ-A, supporting audible and visual alarm signal output. The related programs (such as image recognition, approval processes, and database queries) utilize existing open-source or commercial software (such as OpenCV and WeChat API).

[0066] In summary, the intelligent tool cart proposed in this utility model achieves the following functions through the combination of the above-mentioned existing hardware modules: electronic drawing and automatic updating: based on data synchronization between the communication module and the memory; tool loss prevention: through physical signal linkage of sensors, cameras and alarms; intelligent tool matching: utilizing the interaction function of a pre-stored database and a touch screen.
