Talking about the composition of PCBA proofing and placement equipment

PCBA proofing patchEquipment is a very critical equipment in the SMT proofing process, not only related to the efficiency of patch proofing, but also has a very important impact on the quality of patch components. According to its degree of automation, PCBA proofing and placement equipment is generally divided into manual placement equipment and automatic placement equipment. Among them, automatic placement equipment is the mainstream of current placement and proofing manufacturers. Talk about its composition and structure.

Mechanical body: The mechanical body of PCBA proofing and placement equipment generally adopts a beam structure. The placement head is installed on the beam, that is, the X-direction movement axis. The beam moves in the Y direction on the base. There are several stickers on the placement head of the PCBA proofing and placement equipment. Piece suction nozzle, the suction nozzle performs Z-direction movement and q-angle rotation.

PCB conveying system: The PCB conveying system of PCBA proofing and placement equipment is to transport and fix the PCB board printed with solder paste to the placement position, and then transport the PCB board to the unloading position after the placement is completed. The PCB conveyor system of PCBA proofing and placement equipment can be divided into single table single track transmission form and single table double track transmission form.

Component feeding system: In the PCBA proofing and placement equipment, the feeder provides the components in the package to the suction nozzle according to the instructions of the placement equipment, so the packaging form and quality of the feeder and the placement components are right Picking up components has an important effect. The feeder, also called the feeder, is an important component in the placement technology that affects placement accuracy and production efficiency, so that some PCBA proofing and placement equipment models directly use the number of feeders that can be accommodated as a sign.

Placement head: In PCBA proofing and placement equipment, the placement head of the traditional arch structure has a single nozzle and multiple nozzles side by side structure. The single-nozzle placement head can only place one component in one placement cycle, and the placement accuracy is high. The multi-nozzle parallel placement head has 2-12 parallel nozzle placement axes, which can pick up, correct and place multiple components in one placement cycle, which can effectively improve the placement speed of PCBA proofing and placement equipment.
