Description

Technical Field

[0001] This utility model relates to the field of PCBA motherboard manufacturing technology, and in particular to a surface mount device for PCBA motherboard manufacturing. Background Technology

[0002] PCBA board, translated as Printed Circuit Board Assembly, is an electronic component with specific functions. It is built on the basis of PCB (Printed Circuit Board) and uses processes such as SMT (Surface Mount Technology) and DIP (Dual In-line Package) to mount electronic components (such as resistors, capacitors, inductors, chips, etc.) on the PCB, and performs a series of processes such as soldering and testing.

[0003] The chip mounting device used in PCBA motherboard production feeds the PCB board into the conveyor system. After precise positioning by the vision system, the nozzle picks up the components from the tray according to the program. After inspection and calibration, the components are mounted onto the pads at high speed and with precision. Finally, the components flow out, completing the pre-soldering preparation and achieving efficient and automated production.

[0004] However, dust easily accumulates on the nozzles during operation. This dust can damage the vacuum seal, making it impossible to pick up or causing components to fall off, resulting in placement misalignment and missing components. At the same time, components that are not firmly attached are prone to shifting during movement, causing soldering defects such as tombstoning and bridging. Manual cleaning requires removing the nozzles, which greatly affects work efficiency. Therefore, a surface mount device for PCBA motherboard production is proposed to solve the above problems.
