Conveying device capable of lifting and aligning PCBs through air floating

Abstract

The invention discloses a conveying device capable of lifting and aligning PCBs through air floating. The conveying device comprises a first mounting plate, a first baffle, an electric actuator, a push plate, a vent hole, a first rotating shaft, a first rolling wheel, a second rotating shaft, a second rolling wheel, a second mounting plate, pressure sensors, a second baffle and a blower. Accordingto the conveying device, all parts of aligned PCBs flowing to the second mounting plate are comprehensively weighed by utilizing the matrix-shaped distributed pressure sensors on the second mountingplate, signals are transmitted to the blower in the vent hole in the first mounting plate, according to different weighing sizes, wind generated by the blower is different in size, the aligned PCBs flowing to the first mounting plate can be floated in a horizontal state, then the push plate is driven by the electric actuator to push the aligned PCB substrates to reach preset positions, then the electric actuator returns to an original position, production of an automatic production line is realized, so that the aligned PCBs do not rub with the rolling wheels in a carrying process, and lines onthe PCB substrates are prevented from being damaged and abandoned.

Description

technical field [0001] The invention relates to a conveying device, in particular to a conveying device for lifting an entire row of PCB boards by air flotation, and belongs to the technical field of PCB board applications. Background technique [0002] PCB circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves automation and production labor rates. [0003] When the current PCB boards are handled in the processing line and picked up by automatic manipulators, in order to ensure the position accuracy of the PCB boards, it is necessary to perform alignment before the equipment moves. However, during the alignment process, there will be friction between the PCB board and the rollers, resulting in scratches on the ci...
