A: A production line electronic Kanban system is an industrial display terminal mounted alongside the production line that replaces traditional paper Kanbans and whiteboards. It pushes real-time information such as work order progress, SOP/ESOP work instructions, exception calls, and equipment status directly to the operator's view. Simply put, it is not an isolated screen but rather the information outlet for shop floor management.
1. What it displays. Core content typically includes the current work order and model number, planned output versus real-time completion count, first-pass yield, top defect items, ESOP work instructions (including images, videos, and version numbers), Andon call status, and ESD electrostatic discharge workstation monitoring data. Operators can look up and see "what to do now, where the process stands, how to perform the task, and who to contact for issues."
2. Functions across several levels. 1. Line changeover efficiency: Changing paper SOP versions requires printing, distribution, and collection. Electronic Kanbans allow one-click distribution; if a version error occurs, the system blocks it to prevent the use of incorrect process documents. 2. Exception response: When an operator triggers an Andon, the Kanban immediately displays the call location and type, reducing the team leader's response time from several minutes of verbal shouting to seconds. 3. Transparent management: Management can view real-time output for each line from the office without waiting for post-shift reports. 4. Compliance traceability: Viewing records and version switch logs for ESOPs are retained, making audits significantly easier compared to paper files.
3. Practical implementation considerations. The size of the Kanban should not be maximized blindly; workstation-level screens of 21.5 to 32 inches are common, while large screens for the entire line are calculated separately. Content must be tailored by role: operators see yield rates and SOPs, while team leaders see exceptions and personnel data. Avoid cramming all data into a single screen. Additionally, the system must integrate with MES and ESOP systems; otherwise, it functions merely as a media player.
It is recommended to start with a pilot in one workshop or on one line to establish work order progress tracking and ESOP distribution before gradually adding Andon and ESD monitoring features. Do not aim for a full-featured large screen immediately.
