Fully Automatic Indicator Light Production Line
Indicator Light Automatic Manufacturing System is a complete package to create a pilot light, an industrial or a residential signal indicator and an LED indicator lamp. All aspects of the manufacturing process (i.e., insertion of the copper sheet, assembly of circuit boards (PCBs), riveting the housing, fastening with screws, pad printing, and finally packaging the base) have been automated. This manufacturing system is designed for high volume production with high quality while greatly reducing dependence on labor.
This line integrates robotic arms, servo driven riveting systems, automatic screwdriver workstations, and a pad printer for printing logos or ratings. The primary functions performed are the embedding of copper sheets on PCBs, PCB placement, 2 stage riveting (for electrical connector contacts), nut tightness (by automatic means) with rubber o-rings sealing the nuts, pad printing of logos/rating, and the final riveting to seal the covers onto the assemblies. Each of the workstations on the line are controlled by one central PLC with HMI which provides for real-time monitoring of operations and changeover to new recipes. The normal output of the line is 1200 to 2000 assemblies per hour, depending on how the equipment is configured.
Standard delivery: 30-60 days | ROI typically 8-14 months | Customizable for LED and neon indicators
Definition of Indicator Light Automation Assembly Line
An indicator light automatic production line is a fully automated assembly solution designed for the manufacture of indicator lights, display indicators, and LED indicator lights. The assembly line provides for the sequential assembly of mechanical and electrical components where the process includes the following: inserting copper conductive component parts; placing PCBs; riveting contacts; fastening screws and nuts (including the use of rubber sealing rings); applying pad printed ink markings; and finally sealing the base using rivets. The assembly line provides for no manual handling or variation, thereby guaranteeing that each indicator light manufactured meets the same high electrical and mechanical standards. The assembly line is best utilized by manufacturers of industrial control panels, household appliances, automotive dashboards, and signalling equipment.
Copper Insertion → PCB Placement → Riveting (2x) → Screw Fastening → Nut Tightening + Rubber Ring → Pad Printing → Cover Sealing → Final Riveting.
The vision-guided robots accurately position copper and circuit board component pieces. Riveting force and screw torque are digitally controlled.
An optional electrical continuity test, riveting force monitoring, and vision inspecting can be added at the critical assembly points.
Allows manufacturers to changeover between different sizes of indicator lights (8mm, 12mm, 16mm, 22mm) in less than 30 minutes using recipe based settings.

Most Common Questions
This line will produce round panel indicator lights with standard sizes of 8mm, 12mm, 16mm, 22mm and can produce custom rectangular and miniaturized sizes with custom tooling.
The line offers electrical testing (continuity, LED brightness, polarity) as an option to be integrated after final assembly. We recommend to add a test module to ensure the highest quality assurance.
Yes, both indicator lights use a similar assembly process, however proper handling of the PCB when assembling LED panel indicators is critical. The line is capable of assembling both LED and Neon indicator lights; therefore, we will adapt the PCB mounting setups and screw fastening set-up to support your individual design.
Changeover for electrical parameter changes (color and voltage) are done via the recipe on the HMI – no changes are needed to the machines mechanically; for panel indicator lights that have different physical dimensions (e.g., 16mm vs. 22mm), it should take approximately 30 minutes to change tooling.
The line produces between 9,600 and 16,000 units per 8‑hour shift (1,200–2,000 per hour), depending on the number of parallel stations and indicator complexity.
