Automated Production Lines

The automated production line design solution is a flexible production model that connects various adjustable workstations, tooling fixtures, equipment, and machine tools, integrated with automatic conveying devices. Through the automated production line software management system for information coordination, the design solution combines multiple production modes to reduce production costs and make the best use of resources.

By implementing this automated production line design, workers are freed from heavy physical labor, partial mental labor, and harsh or dangerous working environments. With the support of the automated production line, employees can operate multiple machines or perform multiple tasks simultaneously, greatly improving labor productivity. This enables flexible automated production for multi‑variety, small‑ and medium‑batch manufacturing, while significantly reducing equipment investment and maintenance costs.

The automated production line design solution effectively integrates microelectronics, computer technology, and systems engineering to resolve the conflict between high automation and high flexibility in mechanical manufacturing. It enables the simultaneous production of multiple product varieties on a single production line, allowing enterprises to adjust production models and output according to demand, thereby enhancing their production adaptability and responsiveness.

Service Focus:

The automated production line design solution is divided into three phases: production line optimization and design phase, production line fabrication and trial operation phase, and production line operation phase. The solution will provide production line layout planning, finished line deliverables, and operational guidance. We begin by conducting a survey to understand the current status of the client’s production line, then focus on simple automation as the core, designing the line by replacing manual operations with equipment, jigs, and fixtures. Lean methods are adopted to achieve one-piece-flow just-in-time production. Information management is implemented through the solution to enable data collection, process monitoring, TPM equipment management, quality management, production scheduling, and statistical data analysis throughout the entire production process, thereby creating a low-cost, high-quality, and high-efficiency smart compact Cell production line.

During the implementation of the production line automation design solution, we will:

1.Introduce lean production methods, focusing on leveling, just-in-time, and jidoka (autonomation) as core improvement principles to optimize processes, improve motions, and enhance quality, achieving an efficient, high-quality one-piece-flow pull production model.

2.Introduce information management systems for digital, IoT-connected, and visualized management. Data collection is carried out through industrial IoT technology, analyzed by information systems, and feedback is provided via Andon and Kanban, enabling real-time awareness of production line status.

3.Introduce low-cost automation equipment and improve tooling and fixtures. Through mechanization, electrification, and automation, only a small number of employees are required to work with equipment, achieving a flexible production line layout with one person operating multiple machines and automated production.

Introduction to Automated Production Line Design Solutions

The application of automated production line design solutions is extensive. In the machinery manufacturing industry, for example, automated production lines are used in foundry, forging, stamping, heat treatment, welding, cutting, and mechanical assembly. There are also comprehensive automated lines that integrate processes of different natures, including blank manufacturing, processing, assembly, inspection, and packaging. Among these, cutting process automation has seen the fastest development and the widest application in mechanical manufacturing. Common types include: combined machine tool automation lines for processing boxes, shells, and miscellaneous parts; rotary body automation lines consisting of general-purpose, specialized, or dedicated automated machine tools for machining shafts, discs, and rings; and rotor automation lines for processing small parts with simple procedures.

In automated production line design solutions, equipment can be connected in two ways: rigid linkage and flexible linkage. In rigid‑linkage automation lines, there is no buffer storage between processes, and the processing and transfer of workpieces follow a strict rhythm. If one piece of equipment fails and stops, the entire line shuts down. Therefore, high reliability is required for all equipment in rigidly linked automation lines. In flexibly linked automation lines, buffer storage is provided between processes (or sections), so the cycle times of different processes do not need to be strictly synchronized. When a single machine stops briefly, the buffer storage can balance production within a certain time frame without affecting the normal operation of other equipment. Comprehensive automation lines, assembly automation lines, and longer combined machine tool lines often adopt flexible linkage.

The automated production line design solution mainly consists of: the main production line, branch production lines, control systems, and information systems. It can be divided into flexible production line hardware equipment and a flexible production line information management system. In the production line automation design solution, a Lean Cell Line approach is adopted to connect workstations, tooling fixtures, equipment, machine tools, and transport systems to form a flexible production line system. This ensures that product technical requirements are met, production tact time is maintained, product precision is effectively controlled, and product model changes and upgrades are accommodated — achieving high precision, high quality, high reliability, high efficiency, high flexibility, and consistency.

Automated Production Line Hardware Equipment System

① Main Production Line

In the automated production line design solution, the main production line adopts flexible production integration models such as Just‑In‑Time (JIT) production and agile manufacturing management. After rational consolidation and optimization of the production process, appropriate production equipment is deployed. Combined with the rapid changeover of different tools and fixtures, this enables the production of multiple product varieties on the same production line. At the same time, the main line serves as the primary transportation route in the automated production line design, where the transfer of parts and materials between various workstations is completed. The main line handles one transfer cycle of parts and materials at a time.

② Branch Production Lines

In the automated production line design solution, a branch line is set up at each workstation. The branch lines use loading/unloading devices, conveying devices, storage devices, gravity‑fed or force‑fed chutes or tracks, as well as lifting, indexing, and distributing devices to receive and deliver parts and materials. Through the branch lines, the production line automation design solution can process parts and materials that require special handling, enabling simultaneous production of individual components for multiple product varieties. The branch lines can operate in both forward and reverse directions, allowing them to receive parts from the main line and deliver parts to the main line, with the specific receiving and delivery requirements determined by the information system.

③ Control System

In the automated production line design solution, the control system serves as the central nervous system of the flexible production line. It is responsible for information exchange between the actuators and the information system, and controls the actuators to perform specified actions as required. To accommodate the debugging and normal operation of the automated line, the control system has three operating states: manual setup, semi‑automatic, and automatic. In the manual setup state, manual operation and adjustment are possible, allowing individual actions of each equipment unit. In the semi‑automatic state, single‑cycle operation of a single equipment unit is possible. In the automatic state, the entire automated line operates continuously. In the production line automation design solution, information generated from actuator operations is recorded and fed back to the information system for logical calculation and storage, ensuring accurate actions and providing statistical analysis data for future production management.

Automated Production Line Information Management System

① Production Management System

In the automated production line design solution, the information system serves as the upper‑level management system of the flexible production line, primarily utilizing MES (Manufacturing Execution System) and ERP (Enterprise Resource Planning) systems. Its main function is to process product production information, generate data files in a specified format, and dynamically call the corresponding technical documents for each different production run through interface software, transmitting them to the automated production line. Through IoT and monitoring technologies, the production line automation design solution enables real‑time tracking of the flexible production line’s operational status. Based on changes in products or processes, the system pushes the required production data to the corresponding equipment in a timely and accurate manner, while collecting, processing, and feeding back various types of information generated during production, and executing equipment control. Production data generated during the line’s operation is simultaneously uploaded to the information system and stored in its database, providing rich production data for production management.

② Tooling / Tool Management System

In the automated production line design solution, the tooling/tool management system enables real‑time, dynamic, standardized, just‑in‑time, and automated management of the fixtures, tools, and jigs required for flexible production. It comprehensively meets various tool management needs and fundamentally eliminates blind spots and loopholes in tool management. Upon receiving a processing task, the system allows the tooling/tool warehouse to promptly and accurately prepare the required tools and fixtures according to the product‘s process requirements and deliver them to the production workstation, significantly reducing waiting time and improving production preparation efficiency.
