Smart Cabinet | Digital upgrade of small parts materials on single production line of automotive component manufacturing base

In the automotive component assembly production scenario, a single production line has complex assembly processes and requires a wide variety of fastening and sealing small parts materials. The types of screws, washers, and sealing rings that can be regularly controlled by a single production line amount to over two hundred varieties. The quantity of these materials taken at a single time is not fixed, and the daily frequency of requisitioning is high. The traditional open shelving storage and manual paper-based registration management method has continuously caused various operational obstacles, making it difficult to implement the lean management system in the workshop. A certain automotive component production base, in response to the pain points of small part material control on a single production line, planned and deployed the PanShi Electric intelligent weighing container to replace the traditional manual management model, achieving self-service retrieval of all standard parts on a single line, automatic collection of inbound and outbound data, and dynamic monitoring of inventory. By relying on the hardware's supporting functions, it improves the existing process shortcomings and creates a digital model of edge warehouse that can be replicated and promoted in the factory area.

Management difficulties revealed during the operation of traditional manual shelves

Scattered requisitioning often leads to the omission of warehouse records, resulting in discrepancies between the book inventory and the actual quantity.

For over two hundred standard parts on a single production line, the requisitioning is flexible and the scenarios are scattered. Operators take and use the materials as needed, relying on manual handwritten registration, which is prone to omissions, delays, and errors. Over time, the system's book inventory value cannot match the actual on-site inventory, and the material consumption data is difficult to support the workshop's cost accounting and procurement planning management.

Lack of real-time inventory monitoring capability, making the material replenishment rhythm lag behind

Traditional shelves do not have the function of automatic data collection. The remaining quantities of various small parts materials can only be relied on warehouse staff to conduct regular on-site inventories. The interval between the two inventories cannot synchronize the dynamic material consumption, and when the stock of some commonly used standard parts decreases, there is no prompt, which may lead to insufficient material replenishment and temporary waiting for materials on the production line, affecting the production rhythm.

High frequency of requisitioning corresponds to a large number of manual documents, occupying the attention of warehouse staff on repetitive operations such as out-of-stock registration, on-site inventory, and monthly reconciliation. A large amount of energy is consumed on mechanical single-document processing, making it difficult to invest in material coordination and process optimization, resulting in continuous internal human resource consumption.

Mixed storage of multiple specifications of materials increases the probability of assembly mismatch

Over two hundred standard parts with similar appearances are uniformly stacked on the open shelves, without a fixed partitioning structure. During rush production, it is easy to take the wrong material specifications, resulting in assembly rework and increasing the production support costs in the workshop.

The smart cabinets meets the management needs of a single production line

For the unorganized, scattered, and high-frequency requisitioning of small parts materials on a single production line, the PanShi Electric intelligent weighing container relies on functions such as weight perception, self-service access control, and automatic data retention to alleviate various management difficulties brought by traditional shelves and adapt to the daily control requirements of over two hundred standard parts.

High-precision weight perception, automatically retaining each requisitioned data

The interior of the intelligent container is divided into independent, exclusive storage compartments, which can separately store screws, washers, and sealing rings of different specifications, reducing the likelihood of mixed storage and incorrect retrieval. Each storage compartment is equipped with a weight-sensing component, suitable for any scattered material retrieval operations performed by staff. After the staff completes the retrieval and closes the cabinet door, the system calculates the quantity based on the weight difference, eliminating the need for manual scanning or handwritten documentation. Each retrieval action automatically generates a cloud record, fully retaining information such as the operator, retrieval time, and material model, thereby reducing inventory discrepancies caused by human oversight.

24-hour dynamic inventory monitoring, with a backup inventory reminder mechanism

The equipment collects the inventory quantities of each type of standard parts throughout the day, synchronizes the data with the cloud management backend in real time, and managers can view the entire line's material consumption progress through mobile devices or computers. The workshop can set inventory ranges based on the daily production capacity. When the material reserve approaches the set range, the system will send a replenishment prompt, optimizing the material procurement rhythm and reducing the occurrence of material shortage on the production line.

Self-service material withdrawal with multi-identity verification, suitable for continuous production in multiple shifts.

The equipment supports two types of identity verification methods: card swiping and facial recognition. Enterprises can assign corresponding access rights based on positions and shifts, and standardize the material requisition process. The equipment is not limited by working hours, enabling batch assembly during the day shift, regular production during the night shift, and emergency maintenance material requisition to be completed independently without the need for on-site supervision by warehouse staff, thereby reducing repetitive manual distribution and registration tasks.

Automatically generate standardized electronic ledgers to simplify the monthly reconciliation process.

The system continuously collects the entire cycle of usage data and automatically generates exportable electronic ledgers, replacing the daily manual filling of forms and offline verification of physical documents by the workshop, reducing the numerical deviation caused by manual statistics and alleviating the pressure on the storage and administrative positions in handling documents.

Deployment of smart weighing cabinets on a single production line can improve management directions for the harvest.

The assembly quality control of the workshop is optimized.

All kinds of standard parts are stored in separate areas and arranged neatly, reducing the rework caused by incorrect material assembly, stabilizing the consistency of finished product assembly, and reducing the workload of quality inspection support.

The production line operation rhythm becomes more stable.

Relying on real-time inventory monitoring and pre-supply reminder, it alleviates the problem of production line stoppage caused by the shortage of small items, ensuring the orderly implementation of the established production plan in the workshop.

The allocation of warehouse staff is more reasonable.

By eliminating frequent filling of forms, repetitive inventory checks, and dedicated on-site material distribution, the energy of warehouse staff can be released to focus on material coordination, process optimization, and other management work, optimizing the personnel structure of the workshop.

The implementation of lean digital management in the workshop forms a sample.

Realize the digital management of the entire process of small item storage, retrieval, inventory, and traceability for a single production line, forming a standardized transformation plan, which can provide reference for the upgrade of other production lines in the factory, and improve the digital layout of on-site warehouse in the entire factory.

The lean upgrade of automotive component manufacturing requires not only the iteration of core production equipment but also precise control over frequently used small items such as screws, gaskets, and sealing rings. MonolithIoT smart weighing cabinets adopt a lightweight implementation mode, eliminating the need for major modifications to the production line site. They are suitable for real-world working conditions involving over 200 types of standard parts stored in a scattered manner for retrieval, specifically addressing common management challenges such as missed registration, delayed replenishment, and heavy manual tasks. This provides a feasible implementation path for the digital transformation of on-site warehouses in component manufacturing enterprises.
