Fuwei Intelligent Case | AGV Car Material Handling in Class 100 Cleanroom

Project Background

With the continuous development of industrial automation, more and more enterprises are introducing intelligent logistics equipment to improve production efficiency.  This project is to implement an AGV (Automated Guided Vehicle) material handling system in a Class 100 cleanroom of a large flooring production enterprise.  The workshop is located in a closed and unlit environment, with dimensions of 100m * 60m and a large area. It places high demands on the automation, precision, and efficiency of logistics handling.

Project requirements

The main requirement of this project is to enable AGV carts to automatically transport umbrella racks from the coating machine to the cleaning workshop on the second floor, and to be able to transport empty boxes back to their original positions when needed.  During the transportation process, it is necessary to ensure the safety, accuracy, and timeliness of materials, while considering the special requirements of the dust-free workshop environment and the limitations of elevator transportation.

Project difficulties

Elevator transportation restrictions: The width of the elevator door in the workshop is about 1830mm, with an error of about ± 50mm. This requires that the size of the AGV car must be strictly controlled within a certain range to ensure that the car can smoothly pass through the elevator for vertical transportation.

Cleanroom environment: Class 100 cleanrooms have extremely high requirements for environmental cleanliness. During the design, manufacturing, and operation of AGV vehicles, it is necessary to ensure that no dust or pollutants are generated to avoid affecting product quality.

High precision positioning: Due to the large workshop area and the need for precise material handling to specific workstations, AGV vehicles must have high-precision navigation and positioning capabilities to ensure that materials can be accurately delivered to designated locations.

Solution

AGV car selection and design: Based on project requirements, select AGV cars suitable for dust-free workshop environments and customize their design.  The size of the car is strictly controlled within the allowable range of the elevator door width, and it is made of dust-free materials to ensure that no dust is generated during operation.

High precision navigation and positioning: using laser navigation or visual navigation technology to achieve autonomous navigation and precise positioning of AGV vehicles in the workshop.  By arranging landmarks or QR codes, provide precise path guidance and location information for the car.

Intelligent scheduling system: Establish an intelligent scheduling system to automatically plan the transportation path and task sequence of AGV vehicles based on production plans and material requirements.  By monitoring the running status and position information of the car in real-time, optimization and adjustment of the transportation process can be achieved.

Core values

After careful design and implementation, this project successfully achieved the material handling task of AGV carts in a Class 100 dust-free workshop.  The small car can accurately and efficiently transport umbrella frames and empty boxes, greatly improving production efficiency and quality.  Meanwhile, due to the adoption of dust-free design and high-precision navigation positioning technology, the impact of the car on the environment during operation is minimal, meeting the special requirements of the dust-free workshop.
