PCB Conveyors in SMT Lines
Automated Board Transfer
PCB Conveyors move printed circuit boards between machines by themselves. They use belt systems and platforms to keep boards moving. This helps boards travel at the same speed. People do not need to touch the boards as much. This lowers the chance of damage or mistakes. Operators can change how fast the conveyor goes. They can also change the width for different board sizes. This makes the system work for many kinds of boards.
Automation helps keep board quality the same. It also makes things safer for workers. The conveyors have rails that can be moved and speed controls that can change. This helps each board get to the next station on time. Boards do not get stuck or go to the wrong place. Push rods and modular parts help the conveyor work well. These things make it easy to change the setup. They also help make more boards and better boards.
