[0002] At present, with the continuous advancement of social science and technology, the use of electronic products is increasing, and electronic products need to use PCB boards. PCB boards, also known as printed circuit boards, are the support body of electronic components and the carrier of electrical connections of electronic components.

[0003] In the existing PCB manufacturing process, the blank PCB boards need to be placed on a conveying device one by one manually, and then the blank PCB boards are sequentially conveyed to an automatic assembly device to assemble electronic components on the blank PCB boards, and finally a complete PCB board is obtained. Alternatively, mechanical automatic feeding is used.

[0004] With regard to the above-mentioned related technologies, the inventor believes that there is a defect that the empty PCB board needs to be placed on the conveying device manually, which leads to low loading efficiency and low efficiency in processing the PCB board. However, the existing mechanical automatic feeding design has defects, unreasonable structural layout, and is not conducive to data control of PCB board feeding; at the same time, the continuity is poor. Utility Model Content

[0010] The material transfer device is located above the first conveying device and the second conveying device and is configured to assemble the PCB board in the first loading tray into the second loading tray.

[0011] The material moving device includes a multi-axis manipulator, a mounting seat, a material grabbing mechanism, and a CCD guiding mechanism. The mounting seat is arranged at the driving end of the multi-axis manipulator, the material grabbing mechanism and the CCD guiding mechanism are both arranged on the mounting seat, and the CCD guiding mechanism is located outside the material grabbing mechanism.

[0012] The utility model provides a device for feeding and assembling PCBs, which works fully automatically. In the device, a first conveying device is provided to convey a first loading tray, and the first loading tray is filled with PCB boards. A material transfer device assembles the PCB boards on the first loading tray into a second loading tray of a second conveying device, and the PCB boards are transported to the next processing unit through the second loading tray.

[0033] By driving the second lifting drive module, the third conveyor belt module can be connected with the third tray conveying mechanism or the fourth tray conveying mechanism.

[0034] Therefore, the lifting and lowering tray conveying mechanism is composed of the above structure, the second lifting drive module drives the third conveyor belt module to lift, and the third conveyor belt module connects the third tray conveying mechanism and the fourth tray conveying mechanism.

[0035] In some embodiments, the second conveying device further includes a static electricity removal mechanism, and the third tray conveying mechanism includes a fourth conveyor belt module and a tray positioning module.

[0036] The carrier plate positioning module is arranged on the fourth conveyor belt module and is located at an end away from the lifting carrier plate conveying mechanism, and the static electricity removal mechanism is arranged above the carrier plate positioning module.

[0037] Therefore, the anti-static mechanism performs anti-static treatment on the second loading tray to ensure that the PCB board is operated without static electricity and the circuit on the PCB board is safe.

[0038] In some embodiments, a PCB board automatic feeding device further includes a CCD positioning device, which is disposed on the frame and located between the first conveying device and the second conveying device, and the CCD positioning device is located below the material moving device.
