[0051] As Figure 5 shown, the conveying mechanism 4 includes a conveyor 41, a material blocking mechanism 42, a positioning mechanism 43, and a lifting cylinder 44. The conveyor 41 slides left and right along the transverse sliding rail 13. The material blocking mechanism 42 is fixed on one side of the conveyor 41. The positioning mechanism 43 is installed in the middle of the conveyor 41. The lifting cylinder 44 is fixed at the lower part of the pedestal 1. The positioning mechanism 43 includes a guide shaft 436 and a lifting positioning plate 434. The lower end of the lifting positioning plate 434 is fixedly connected to the upper end of the guide shaft 436. The guide shaft 436 and the lifting positioning plate 434 are driven by the lifting cylinder 44 to move up and down vertically.

[0052] Preferably, the number of guide shafts 436 is four. The four guide shafts 436 are arranged in a rectangle.

[0056] The magazine 23 filled with PCB boards 6 is loaded into the feeding mechanisms 2 on the left and right sides. The lifting support block 221 of the feeding mechanism 2 on the left side drives the magazine lifting plate 233 and the PCB board 6 to rise until the opposed sensors 24 sense that the PCB board 6 is in place.

[0057] The manipulator suction mechanism 3 moves to the suction position on the left side of the pedestal 1 to suck the PCB board 6. After the PCB board 6 is sucked, the four-axis robotic arm 31 moves the suction cup jig 34 and the PCB board 6 to the placement area at the rear of the pedestal 1. The conveyor 41 moves the carrier 7 to be close to the placement area, and the material blocking assembly 42 rises.

[0058] After the carrier 7 moves to the placement position, the lifting cylinder 44 rises, and the four positioning pins 435 are inserted into the positioning holes of the carrier 7. The four-axis robotic arm 31 moves down to the placement height, the suction nozzle 36 releases, and the PCB board 6 falls into the carrier 7, completing the loading of the PCB board 6. The positioning mechanism 43 and the material blocking assembly 42 descend, and the conveyor 41 moves the carrier 7 with the PCB board 6 placed therein to the next workstation.

[0059] While the positioning mechanism 43 and the material blocking assembly 42 are descending, the four-axis robotic arm 31 moves to the suction position on the right side of the pedestal 1 to suck the PCB board 6, and repeats the above steps to execute the process of feeding the right magazine 23 and the four-axis robotic arm 31 sucking the PCB board 6 until two carriers 7 with PCB boards 6 are moved to the workstation, completing one working process.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
