The working principle of the insertion machine mainly involves the automatic and standard insertion of electronic components into the conductive through holes of the printed circuit board. This process is achieved through mechanical equipment and usually includes the following steps:
Circuit board transfer and calibration: First, the printed circuit board (PCB) moves smoothly through the conveyor belt on the automated production line to the working area of the insertion machine. Here, a sophisticated vision system is responsible for locating and calibrating the position of the PCB to ensure the accuracy and stability of subsequent component insertion.
Automatic component feeding: Next, the insertion machine automatically selects the required electronic components from the storage bin through preset program control. After precise positioning and attitude detection, these components are ready to be accurately placed at the predetermined position on the PCB.
Accurate insertion: The pneumatic system plays a key role, which is responsible for sucking the components from the feeder and accurately placing the components into the preset holes of the PCB through a high-precision mechanical structure. This step marks the official start of automated assembly of electronic components.
Soldering Fixation: When all necessary plug-ins are installed on the PCB, the entire PCBA (assembled printed circuit board) is transferred to the wave soldering equipment for soldering. Wave soldering equipment controls the temperature of the molten tin furnace and the working status of the heating tube to firmly solder the components with exposed pins and the components on the back to the PCB.
Quality inspection and adjustment: After completing the welding, the PCBA will go through strict quality inspection to ensure that all components have been installed and welded correctly. If any problems are found, such as component misalignment or poor welding, the insertion machine can adjust the movement path and speed according to preset programming to adapt to components and PCBs with different specifications and requirements. Afterwards, the insertion and welding processes can be repeated until predetermined quality standards are achieved.
