Description

Technical Field

[0001] The utility model relates to the field of PCB board processing, in particular to a turnover mechanism for PCB board processing. Background Technique

[0002] The Chinese name of the PCB board is printed circuit board, also known as printed wiring board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. During the processing of the PCB board, after one side of it is processed, the PCB board needs to be flipped 180 degrees, and then the back side is processed again;

[0003] In the prior art, a turnover mechanism for PCB board processing proposed in the utility model patent with the publication number of CN 219269194 U, through the mutual cooperation of an operation board, a conveyor belt, a plate placing frame, gears, and racks, can convey the PCB board along the length direction of the operation board. When the PCB board is conveyed to the position of the housing, it drives the PCB board to flip 180 degrees. The turnover mechanism is directly arranged on the conveyor belt, and its volume is small, which can ensure that the operators on both sides of the housing can process both sides of the PCB board respectively;

[0004] However, its turnover mechanism is relatively complex. It is necessary to install a plate placing frame on the conveyor belt, which is not convenient to use and has a certain impact on the load of the conveyor belt. After the PCB board is processed by turnover, it still needs to be manually taken and placed, and the operation is too cumbersome, and the practicability is not good. Therefore, we need to upgrade and transform on the basis of the prior art to overcome the problems and deficiencies it has. Content of the Utility Model

[0005] The purpose of the utility model is to provide a turnover mechanism for PCB board processing to solve the problems put forward in the above background technique.
