In traditional industrial automation environments, to ensure personnel safety, robotic arms are usually isolated by fixed fences or surrounded by bulky safety light curtains. This' hard isolation 'approach sacrifices the flexibility and productivity of human-machine collaboration.

Faced with the demand for small batch and multi variety production modes in modern manufacturing, close collaboration between humans and machines has become the key to improving production efficiency. Traditional safety light curtains have limitations such as insufficient flexibility, limited installation space, and high cost, making it difficult to meet the needs of flexible production

Innovation Highlight 1: Flexible Installation

Traditional light curtains are almost entirely based on the principle of opposition, with separate transmission and reception, which requires two installation ends and limited installation and usage scenarios.

Unlike traditional safety light curtains that require opposite installation, Meiji Sensing's solution can be directly integrated into the robotic arm body. This integrated design significantly saves equipment space and simplifies system integration.

Innovation Highlight 2: Rapid Response

The Meiji sensing solution adopts the principle of optical reflection and non-contact detection, with a rapid response speed of ≤ 5ms and a long detection distance, ensuring timely stopping of the robotic arm movement before potential hazards occur.  

The Akusense Sensing human-machine collaboration safety solution effectively avoids harm to operators caused by robotic arms, while ensuring that production pace is not affected. The economic benefits brought are obvious.

1. The significant reduction in human-machine collaboration distance has made the production line layout more compact, reduced equipment footprint, and optimized space utilization.

2. Due to the direct integration of safety protection into the robotic arm, there is no need to establish a large safety isolation zone. Personnel can quickly approach the equipment for maintenance and debugging work, significantly reducing production interruption time.

3. When personnel approach, the robotic arm automatically slows down or pauses; Once the personnel leave, the robotic arm immediately resumes operation, avoiding the common recovery delay in traditional safety systems.

Scenario 1: Semi automatic assembly

In the semi-automatic assembly workshop for electronic products, operators collaborate with robots to assemble complex components. When the operator approaches the robot operation area with small parts to prepare for docking, the circular safety light curtain quickly forms a dynamic safety isolation zone to monitor the hand position in real time. If the hand enters the danger zone, immediately pause the robot and it will automatically resume after exiting. This mode leverages the advantages of robots to ensure personnel safety, improve assembly efficiency, and enhance product quality.

Scenario 2: Workpiece replenishment

When the operator replenishes the workpiece tray, the robot can continue to operate normally without the need for overall shutdown, improving processing efficiency. At the same time, the circular safety light curtain is constructed for safety protection, ensuring that there is no risk of hand squeezing in human-machine cooperation and enhancing workers' acceptance of the collaborative mode.

This evolution from passive protection to active collaboration is a key breakthrough in the flexibility of production lines. This marks a new stage of "zero accidents and high efficiency" in human-machine collaboration. The balance between its economy and innovation is injecting safer and smarter genes into intelligent manufacturing.
