Conveying device for double-sided detection of PCB board and conveying method thereof

Abstract

The invention discloses a conveying device for double-sided detection of a PCB board and a conveying method thereof. The conveying device comprises a rack, a positioning mechanism, a material taking mechanism, and a material guiding mechanism. Under the driving of a material taking and driving unit, the PCB board to be detected can be grabbed onto a positioning platform by a material taking and grabbing module, then, the material guiding and grabbing module grabs the positioned PCB board to move to a detection station to detect the first side of the PCB board, the material taking and grabbingmodule is driven to overturn by a overturning and driving unit, the material guiding and grabbing module grabs the PCB board subjected to detection of the first side to the material taking and grabbing module, then the overturning and driving unit drives the material taking and grabbing module to overturn reversely to realize side turning of the PCB board, then the PCB board is placed on the positioning platform for positioning, the material guiding and grabbing module grabs the positioned PCB board to move to the detection station to detect the second side of the PCB board, and the PCB boardis positioned before each side of the PCB board is detected so that the conveying precision of the PCB board can be guaranteed, the detection accuracy of the PCB board is improved, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of PCB board manufacturing equipment, in particular to a delivery device for double-sided detection of PCB boards and a delivery method thereof. Background technique [0002] Traditional PCB board production and testing factories are transforming into automated production lines. With the development of machine vision, its technology is becoming more and more mature, and the cost continues to decrease. At present, many PCB board inspection workshops in China have begun to introduce visual inspection equipment to replace labor, which has greatly improved the inspection efficiency. When double-sided inspection of PCB boards , now the automatic production line uses intelligent manipulators to control the action of intelligent manipulators by setting different programs. On the one hand, this requires complex and sophisticated programs, which makes the price too high and is difficult to be accepted by most users. ...

With the development of machine vision, its technology is becoming more and more mature, and the cost continues to decrease. At present, many PCB board inspection workshops in China have begun to introduce visual inspection equipment to replace labor, which has greatly improved the inspection efficiency. When double-sided inspection of PCB boards , now the automatic production line uses intelligent manipulators to control the action of intelligent manipulators by setting different programs. On the one hand, this requires complex and sophisticated programs, which makes the price too high and is difficult to be accepted by most users. On the other hand, The traditional PCB board inspection table still has a long service life, and it will cause waste if it is directly scrapped; some PCB boards are turned over by a flipping device, but the positioning accuracy is difficult to guarantee due to the huge moment of inertia of the PCB board, and the PCB board The test bench cannot detect
