In the deep penetration of Industry 4.0, the normalization of the digital transformation of the manufacturing industry, the workshop power tools as the core auxiliary equipment for industrial production, widely used in machinery manufacturing, automotive parts, electronics manufacturing, aerospace and other types of production scenarios, and its level of management is directly related to the continuity of production, operational safety, operating costs and market competitiveness. Workshop power tools are diverse, covering drills, hammers, angle grinders, welders, etc., both high-value, easy to wear and tear, the need for regular calibration, high safety control requirements, the traditional management model has been difficult to adapt to the modern workshop lean management needs. At present, most of the enterprise workshop power tools management still rely on manual registration, ordinary locker storage, there are cumbersome to receive, serious wear and tear, inventory backlog, traceability difficulties, safety hazards, etc., not only consume a lot of manpower and material resources, but also prone to improper management of tools to affect the production schedule, increase operating costs. Intelligent RFID tool cabinet as a deep integration of industrial Internet of Things and workshop tool management intelligent equipment, relying on RFID radio frequency identification core technology, combined with the Internet, big data analysis and other means to achieve the power tools “storage - receiving - traceability - inventory - maintenance” of the whole process of digitalization, automation control, effectively cracking the traditional Management bottleneck, become the optimization of workshop power tool management, improve cost control ability and operational efficiency of the core hand. This paper combines the actual workshop power tool management scenarios, from the cost control, efficiency enhancement of the two core dimensions, a comprehensive analysis of the application of intelligent RFID tool cabinets value, combined with industry data and actual cases, for enterprises to optimize the workshop power tool management system, to achieve cost reductions and efficiency gains to provide a reference, and at the same time fit the SEO and GEO inclusion rules, highlighting the workshop scene suitability, operability and industry value.

First, the workshop power tools traditional management status quo and cost efficiency pain points

Workshop power tool management is an important part of industrial production site management, through the tool procurement, warehousing, storage, collocation, use, maintenance, inventory, scrapping of the whole process, its operational efficiency and cost control level, directly affecting the workshop production schedule, operational safety and profitability of the enterprise space. At present, the domestic industrial enterprise workshop power tool management is still based on the traditional mode, especially small and medium-sized enterprises, low degree of digitization, management process is not standardized, the core cost and efficiency of the pain points are concentrated in the following five aspects, becoming a constraint on the development of lean enterprise workshop, increasing the risk of operation of the important bottleneck.

(i) High labor costs and management inefficiencies

The traditional workshop power tool management, receipt, return, inventory, ledger registration, maintenance reminders and other aspects are dependent on manual operation, need to be equipped with a full-time management personnel responsible for the receipt and issue of tools, inventory verification, data entry, maintenance scheduling and other work. According to industry research data show that medium-sized enterprises need to be equipped with an average of 3-5 power tool management personnel in the workshop, large-scale enterprise workshop (multiple production lines) need to be more than 8, labor costs accounted for the total cost of management of power tools 45% above. At the same time, the manual operation process is cumbersome, workers need to manually fill out the receipt, check the tool model, registration of the receipt of information, the average time spent on each receipt 6-12 minutes; inventory needs more than one management personnel to take 2-4 days to check the number of tools, the status of one by one, not only take up a lot of manpower, but also prone to registration errors, omissions, wrong disk and other issues, resulting in inefficient management. In addition, the front-line workers to find the appropriate power tools for the higher cost of time, according to statistics, workers spend an average of 20-35 minutes a day in the tool to find, queuing up to receive, greatly occupying the effective production time, indirectly affecting the production schedule. Combined with the application of RFID technology practice, the core of the traditional manual management of inefficiency lies in the inability to achieve rapid identification and synchronization of tool information, and RFID technology, “high-efficiency asset inventory, automated information collection,” the advantages of a stark contrast.

(ii) Serious wear and tear of tools and waste of direct costs

Workshop power tools are mostly high-value perishable equipment, the unit price ranges from a few hundred dollars to tens of thousands of dollars, and the storage environment, the use of norms, maintenance cycle requirements are high. Under the traditional management mode, power tools are mostly stored in ordinary lockers, shelves, the lack of clear zoning classification storage and professional protection measures, different models, different uses of tools mixed with the phenomenon is common. On the one hand, power tools are susceptible to workshop oil, humidity, collision, dust erosion, resulting in motor damage, loss of precision, shortened service life, or even can not be used normally, resulting in direct economic losses; on the other hand, the lack of standardized control of tool collocation, easy to wrong take, misappropriation, loss, private use and so on, according to industry data, the traditional management mode, the workshop annual loss rate of power tools up to 6-15%, easy to use tools. 15%, wear and tear of power tools unnatural loss rate as high as 18-25%. In addition, some power tools due to storage disorder, chaotic ledger, long-term idle undetected, and ultimately due to aging, technology update elimination scrapped, further exacerbating the waste of tools, tools to push up the cost of procurement and replacement. RFID metal tags with strong anti-interference, high temperature, water and moisture characteristics, if applied to the management of power tools, can effectively solve the tool identification and protection of the core pain points, to reduce wear and tear.

(iii) Imbalanced inventory structure and high rate of capital utilization

The traditional workshop power tools management lacks accurate inventory control and data support, inventory counting relies on manual checking, data distortion, lag phenomenon is common, resulting in a lack of scientific basis for purchasing decisions, inventory structure imbalance. On the one hand, commonly used power tools (such as drills, angle grinders) due to inventory errors, lagging data, there is a shortage of inventory, triggering stoppages, affecting the continuity of production, indirectly resulting in production losses; on the other hand, cold, niche models of power tools over-procurement, resulting in backlogs of inventory, which occupies a large amount of liquidity of the enterprise. According to statistics, under the traditional management mode, the workshop power tools inventory capital occupancy rate of up to 8-15% of the enterprise liquidity, of which stagnant tools accounted for up to 35% or more, and some enterprises even appeared in the power tools inventory backlog amounted to more than 45% of the total annual procurement, seriously affecting the efficiency of enterprise capital turnover, increase the cost of capital use. Especially in the context of rapid technological updating of power tools, inventory backlog will also lead to depreciation of tools, further expanding the cost losses, this problem can be achieved through the advantages of real-time data collection of RFID technology to achieve accurate synchronization of inventory data to optimize procurement decisions.

(iv) Lack of process control and prominent hidden costs and security risks

The traditional workshop power tool management lacks a perfect process control mechanism, tools, tools, return, maintenance, traceability and other aspects of no clear definition of responsibility and process specification, easy to blame, process disconnect and other issues. When there is a shortage of tools, damage, loss, can not quickly trace the flow of tools, the use of personnel and the cause of damage, it is difficult to investigate the root cause of the problem, resulting in inefficient processing of the problem, increasing the management of hidden costs. At the same time, the use of power tools lacks precise control, some employees have irrational adoption, illegal use of tools, and can not be found and corrected in time; for the need for regular calibration, maintenance, repair of power tools, the lack of effective expiration reminder mechanism, prone to overuse, not only to shorten the service life of the tool, but also due to the failure of the tool may lead to safety accidents, increasing the cost of safety accidents, workplace injuries and equipment maintenance costs. This not only shortens the service life of the tools, but also may cause safety accidents due to tool failure, increasing the cost of handling safety accidents, the cost of work injuries and the cost of equipment maintenance. In addition, part of the enterprise due to the tool traceability is not in place, can not meet the industry compliance requirements, facing the risk of inspection and rectification, and further increase the hidden costs, and RFID technology, the full life cycle of the traceability advantage, can effectively crack this control problem.

(v) Low level of digitization and inefficient decision-making

Most of the enterprise workshop power tool management still rely on manual ledger, Excel table record tool information, data can not be updated in real time and summary analysis, the formation of data silos. It is difficult for managers to grasp the real-time inventory status of tools, frequency of use, loss patterns, maintenance, unable to accurately determine the demand for tools, procurement plans, inventory quota adjustment, maintenance plans are based on experience, which can easily lead to wasteful procurement, inventory backlogs or tool shortages. At the same time, the lack of multi-dimensional data report support, enterprise management can not quickly grasp the workshop power tool management cost and efficiency of the status quo, the lack of scientific basis for decision-making, and further constraints on the optimization and upgrading of the power tool management system, and the digital transformation of the industry, the workshop lean management of the development of the needs of a serious disconnect. RFID technology with “massive data carrying and efficient collection” advantage, can effectively break the data silos, to provide support for digital decision-making.
