Why Did the Carpenter Put Down the Nail Gun? 🪚 In 2025, a company called ‘Kongkan Jejakso’ brought a new breeze to the construction site by introducing ‘robots’ into wood assembly. 🤖

If you thought, “Wait, do robots even drive nails into wood now?” this case study will change your mind.

Gonggan Jejakso is a specialist in modular housing. To establish consistent quality and an efficient production system, they introduced industrial robots. As a result, they succeeded in automating the window frame assembly process, reducing work time by 40%.

But why did they choose to introduce robots? How was work time reduced by 40%? What role did Marosol play in this project? Let’s head into the vivid scene of the action right now. 🏃‍♂️

Robots, Not Carpenters, Assemble Wooden Window Frames? 🤔

Among construction processes, window frame assembly is particularly labor-intensive. This is because frame shapes vary by the dozens depending on window size and opening shapes, and the joining of each part must be executed with high precision.

Previously, skilled technicians had to manually lift the wood, align it, and secure it with nail guns to complete the frames. The problems were as follows: 👇

✅ Limited production due to a shortage of skilled workers. ✅ Increasing the workforce was necessary to respond to diverse orders. ✅ High fatigue from transporting heavy materials and repetitive tasks. ✅ Difficulty in real-time task management due to the large and complex site environment.

To solve these issues, Kongkan Jejakso introduced a robot automation system.

Marosol Solution 1: KUKA Robot + Dedicated Gripper + High Payload Track Motion

Marosol designed the optimal combination for ‘Window Frame Assembly Automation’ in this project.

🎯 The Core Configuration: KUKA KR 210 R3100 Industrial Robot Capable of lifting up to 210kg with a working radius exceeding 3 meters.

Custom-Designed Robot Gripper Recognizes the shape and position of the wood, delicately grips it, and moves it. High Payload Track Motion Covers a wide work area and helps move heavy window frames freely.

What happens when these three are combined? The process of ‘material alignment → assembly → moving’ previously done by humans is now handled by the robot—accurately and quickly. Let’s look closer at how the automation line is structured.

At the center of the automation line sits a KUKA high-payload industrial robot. It performs tasks while moving along a Track Motion installed on the factory floor. The robot’s end-effector is equipped with a customized gripper specialized for handling wooden components.

The core of this system is the organic integration of the 6-axis industrial robot and peripheral devices. Kongkan Jejakso introduced the ‘KR R3100’ model from Germany’s KUKA. This robot can lift up to approximately 120kg and cover a wide working radius of over 3m. This allows it to easily handle large, heavy window frames or wooden panels.

The robot moves along a High Payload Track Motion to access multiple work points along a long assembly table. This track acts like a linear rail, expanding the robot’s working range several times over, allowing a single robot to cover a vast area. It can even transport panel frames weighing hundreds of kilograms.

Another crucial element is the dedicated gripper. This gripper is designed to pick up and align wooden parts, and perform nailing or stapling while holding them in place. It essentially replaces dangerous tasks that previously had to be done by human hands. Furthermore, the gripper is equipped with pressure sensors and vision cameras. This allows it to accurately and stably grip wooden components of various sizes and place them precisely in designated positions.

Marosol Solution 2: Real-time Process Monitoring System, SOLlink INDUSTRIAL 🧠

Automation isn't just about machines; management and control are vital. Therefore, Marosol also built SOLlink INDUSTRIAL, a smart factory solution that can monitor manufacturing processes in real-time and immediately detect errors. SOLlink is a cloud-based integrated robot control platform developed by Bigwave Robotics. It allows for the real-time monitoring and control of multiple robots and peripheral equipment on a single screen.

Through this system, the factory can check the status of robots and work progress in real-time, issue necessary instructions, and collect/analyze data. It allows for the integration and remote control of heterogeneous robots, meaning that even if more robots are introduced or processes are expanded, they can be managed within a single platform. Thanks to SOLlink, immediate responses to unexpected issues are possible, and data-driven predictive maintenance has become a reality. Ultimately, the organic linkage of hardware (robots, grippers, track motions) and software (SOLlink system) allowed Kongkan Jejakso to realize smart automation of the window frame assembly process. 🙌

Process Flow at a Glance 👀

From Material Input to Window Assembly and Frame Movement

The automation system handles the window frame assembly within the wooden panel manufacturing process. The entire process is divided into three stages:

1️⃣ Material Input and Alignment Once the cut and processed wooden parts are supplied, the robot picks them up one by one with its gripper and aligns them in designated positions. Based on BIM drawing information and the SOLlink system, components are placed precisely according to the window's position and size.

2️⃣ Window Frame Assembly Once the parts are in place, the robot performs nailing (stapling) at precise locations. Robots safely handle dangerous tasks and flexibly assemble according to 44 different window patterns.

3️⃣ Frame Movement and Connection to the Next Process Finished panels are moved along the track by the robot to the next station. Heavy frames can be transported stably, enabling logistics automation without the need for cranes or forklifts.

In summary... Material placement → Window assembly → Panel movement The entire process is handled automatically within a single robot cell. Workers only handle auxiliary roles like material setting or final inspection, while the robot takes responsibility for dangerous and repetitive assembly.

What Makes Kongkan Jejakso’s Automation System Special? 🔧

This system goes beyond simple mechanization; it is a smart solution with flexibility, precision, real-time management, and safety.

✅ Handles Diverse Window Patterns with Ease The system is designed to respond to 42 different window patterns. Even wall structures with slightly different window sizes or positions can be automatically assembled using programs tailored to each pattern. It is easily expandable by simply adding programs for new patterns, which is especially useful in the highly customized field of residential construction.

🎯 Accurate Work, Consistent Quality Robots consistently perform precision tasks that are difficult for humans to repeat. Because the nailing positions and component spacing are always identical, high-quality results are produced without deviation. Since automation, the defect rate has dropped significantly, and insulation performance and finish quality have improved.

🦺 A Safe Working Environment Robots take over dangerous tasks like lifting heavy wood or operating nail guns. This reduces the risk of worker injury and creates a more pleasant environment by reducing noise and dust. Safety fences and sensors ensure there is no collision between humans and robots.
